It has good refractory and heat insulation effects, improves the integrity of kiln refractory and heat insulation and overall energy saving, and promotes the technological progress of kiln engineering. However, due to material and other reasons, the product quality and performance of most existing ceramic fibers are not very stable, and the overall insulation effect needs to be strengthened.

Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

Embodiment 1

As shown in FIG1 , a ceramic fiber folding module includes:

A fiber blanket 001, wherein the middle portion of the fiber blanket 001 is folded to form a folding module, and both ends of the fiber blanket 001 are bent to form a continuous bow shape, and the continuous bow shapes at both ends can be interlocked;

Compensation blocks 002, which are arranged inside the arched protrusions at both ends of the fiber blanket 001;

It also includes a continuous arched wooden board 003 for packaging arranged outside the fiber blanket 001 and the compensation block 002. The continuous arched wooden board 003 is arranged on both sides of the fiber blanket 001 and is used to fix and compress the fiber blanket 001 while maintaining the continuous arched shape at both ends of the fiber blanket 001.

The fiber blanket 001 is prepared from raw materials with the following specific gravity: 35-49% alumina, 40-53% quartz sand, and 0-25% zircon sand.

The fiber blanket 001 is prepared from raw materials with the following specific gravity: 40-45% alumina, 45-50% quartz sand, and 5-15% zircon sand.

Preferably, the fiber blanket 001 has a volume density of 160-240 kg.m³, a thickness of 150-350 mm, and a thermal conductivity of no more than 0.15 W/m·K.

The fiber blanket 001 has a classification temperature of 1430°C and a continuous use temperature of 1360°C.

In this embodiment, continuous bows are provided at both ends of the fiber blanket 001, and compensation blocks 002 are provided at the protruding parts of the continuous bows, so that two adjacent fiber modules are more closely connected when the fiber modules are installed and used. Through the design of the continuous bows, a longitudinal force is applied to the connection between the two fiber modules, so that the edges of the fiber modules are connected more closely, thereby improving the service life of the fiber modules.

In detail, in the prior art, by folding the ceramic fiber modules, adjacent fiber modules are subjected to a lateral mutual pressure, thereby promoting a tight connection between the folding modules. However, the edge corners of the folding modules are subjected to a relatively small lateral pressure. After long-term use, oxidation is likely to occur first due to the loose connection, resulting in a decrease in the thermal insulation effect. By providing a continuous bow-shaped structure at both ends of the folding module, when the two adjacent folding modules are installed, the two ends of the folding module can be subjected to a vertical pressure. The vertical pressure is used to make the connection between the two folding modules tighter, thereby improving the life of the folding module.

It should be noted that the continuous arches provided at both ends of the same folding module can be interlocked with each other, thereby facilitating standardized production and subsequent use and installation.

It is worth mentioning that by filling the compensation block 002 inside the protruding part of the folding module, on the one hand, it is beneficial for the protruding part to maintain its shape, and on the other hand, the compensation block 002 is used to further increase the size of the vertical pressure, making the connection tighter while reducing the appearance of gaps.

Embodiment 2

Further, as shown in FIG2 , a preparation process of a ceramic fiber folding module includes a spinning process, a cotton collecting process, a needle punching process, a water cutting process and a folding and packaging process which are sequentially arranged backwards, and the folding and packaging process includes the following steps:

Step 1, folding step, first fix the fiber blanket 001, then fold the middle of the fiber blanket 001, and leave a part of the fiber blanket 001 free at both ends;

Step 2, forming and coating step, after folding, the free parts at both ends of the fiber blanket 001 are formed, the two ends of the fiber blanket 001 are pressed into a continuous arch shape, and during the forming process, the compensation block 002 is filled into the groove of the fiber blanket 001, and after forming, a protective layer is coated on the lower surface of the continuous arch part of the fiber blanket 001;

Step 3, a compression step, wherein the continuous arched portion in a horizontal state is bent into a vertical state and pressed against the middle of the fiber blanket 001, and the continuous arched protruding portion is compressed during the bending process;

Step 4, the assembly step, is to attach the continuous arched wooden board 003 to both ends of the fiber blanket 001, and compress the entire board 003, and then bundle the compressed modules to complete the production.

Furthermore, the protective layer applied in the molding and coating steps is made of polyvinyl chloride or silicone rubber.

Furthermore, the compensation block 002 is in the shape of a square bar.

Furthermore, in the compression steps of the compression step and the assembly step, the compression ratios are both 20%-35%.

Furthermore, in the water cutting process, the formed product is water cut at a water cutting pressure of 25 MPa.

Embodiment 3

Further, as shown in FIG3 , a production device for a ceramic fiber folding module includes:

A folding mechanism 1, wherein the folding mechanism 1 is used to fold the fiber blanket 001;

A shaping mechanism 2, which is arranged on both sides of the folding mechanism 1 and is used to shape the bows at both ends of the fiber blanket 001;

A coating mechanism 3, which is arranged below the shaping mechanism 2 and is used to coat the two ends of the fiber blanket 001 with a protective layer;

The assembling mechanism 4 is arranged below the folding mechanism 1 and is used to assemble the ceramic fiber folding module into shape.

In this embodiment, by providing a shaping mechanism 2 and an assembling mechanism 4, the setting of the continuous arched structures at both ends of the fiber blanket 001 and the assembly of the fiber folding module as a whole are achieved.

In detail, the folding mechanism 1 folds the middle part of the fiber blanket 001, and leaves one end at each end for setting the bow structure. The shaping mechanism 2 shapes the remaining parts at both ends of the fiber blanket 001 into a continuous bow shape and fills it with the compensation block 002. The coating mechanism 3 coats the formed continuous bow part with a protective film, and the assembling mechanism 4 assembles and shapes the fiber module as a whole to complete the production.

It should be noted that shaping, coating and assembly of both ends of the fiber blanket 001 are completed simultaneously, thereby reducing processing time and improving production efficiency.

It is worth mentioning that after the continuous arch structure is set by the shaping mechanism 2, a protective film is coated on the surface of the fiber blanket 001 by the coating mechanism 3, and multiple means such as extrusion are used during assembly to jointly improve the tightness of the connection of the fiber modules.

Further, as shown in FIG. 4 , FIG. 10 , and FIG. 11 , the folding mechanism 1 includes a frame for estimating various components, and also includes a first guide rail 11 arranged on both sides of the frame, two sets of sliders 111 arranged at both ends of the guide rail and driven by a linear motor to realize horizontal movement, a second guide rail 12 vertically arranged on the slider 111, and an electric clamp 121 slidably connected to the second guide rail 12 for fixing the fiber blanket 001;

An upper folding frame 13 which is respectively arranged on the upper and lower sides of the middle part of the fiber blanket 001 and is driven by a telescopic cylinder to move up and down, a lower folding frame 14 which is fixedly connected to the frame, and a plurality of telescopic rods 141 arranged on the folding frame.

In this embodiment, the fiber blanket 001 is folded by setting up an upper folding frame 13 and a lower folding frame 14. Before folding, the fiber blanket 001 is fixed by an electric clamp 121. At the same time, the setting of the first guide rail 11 and the second guide rail 12 enables the electric clamp 121 to cooperate with the components to complete the movement of the position of the fiber blanket 001.

In detail, the four corners of the fiber blanket 001 are fixed on the electric clamp 121, and the upper folding frame 13 moves downward to press the fiber blanket 001, so that the fiber blanket 001 is folded in cooperation with the lower folding frame 14. While folding, the electric clamp 121 moves with the fiber blanket 001, so that the fiber blanket 001 always remains in a straight state to avoid wrinkles. When the folding is completed, the electric clamp 121 keeps the empty parts at both ends of the fiber blanket 001 in a horizontal state.

It should be noted that the upper folding frame 13 and the lower folding frame 14 need to be arranged in coordination, and the arrangement on the upper folding frame 13 ensures that the remaining parts at both ends of the fiber blanket 001 after folding are located at the bottom, thereby facilitating the processing of the bow-shaped structure.

It is worth mentioning that the provision of the telescopic rod 141 facilitates the upper and lower folding frames 14 to be separated from the fiber blanket 001 .

Further, as shown in FIGS. 5 , 12 and 13 , the shaping mechanism 2 includes a shaping piece 21 for shaping the two ends of the fiber blanket 001 and a placing piece 22 for cooperating with the shaping piece 21 to complete the filling of the compensation block 002 , wherein the shaping piece 21 includes a lower fixed plate 211 horizontally slidably connected to the lower folding frame 14 and driven by a telescopic cylinder, and an upper fixed plate 212 vertically slidably connected to the upper folding frame 13 and driven to move up and down by a telescopic cylinder;

The lower fixing plate 211 is provided with a plurality of groups of horizontal plates 2111 , and the upper fixing plate 212 is provided with a plurality of groups of vertical plates 2121 .

In this embodiment, by providing the upper fixing plate 212 and the lower fixing plate 211 , the excess parts at both ends of the fiber blanket 001 can be shaped, so that the two ends of the fiber blanket 001 can form a continuous arch structure.

In detail, the upper fixing plate 212 moves downward to press the fiber blanket 001 downward, and the fiber blanket 001 is formed into a continuous arch shape by utilizing the shapes of the horizontal plate 2111 and the vertical plate 2121 .

It should be noted that the vertical plates 2121 on the lower fixing plate 211 and the vertical plates 2121 on the upper fixing plate 212 need to be staggered, and the shapes of the shaping pieces 21 at both ends of the fiber blanket 001 need to match each other to achieve the effect that the two ends of the fiber module in the final product can be embedded with each other.

It is worth mentioning that the edges of the horizontal plate 2111 and the vertical plate 2121 need to be rounded. On the one hand, it is convenient to shape the fiber blanket 001 to avoid damage to the surface of the fiber blanket 001 during movement. On the other hand, the bent part of the fiber blanket 001 is curved to facilitate subsequent painting.

Further, as shown in Figure 6, the placement member 22 includes a card plate 221 arranged at both ends in the middle of each group of vertical plates 2121 and horizontally slidably connected to the upper fixed plate 212, a first gear 222 arranged above the card plate 221 and driving the card plate 221 to slide through a gear rack transmission method, and a first rack 223 fixedly connected to the lower folding frame 14. When the first gear 222 and the first rack 223 move toward each other, the first gear 222 can engage with the first rack 223.

In this embodiment, the compensation block 002 is placed by providing a clamping plate 221 in coordination with the movement of the fixing plate 212, and the compensation block 002 is filled into the groove while continuous bow forming is being performed.

In detail, the compensation block 002 is placed in the middle of each group of vertical plates 2121 of the upper fixed plate 212 of the guide groove, the upper fixed plate 212 moves downward, the first gear 222 engages with the first rack 223 to rotate, and drives the clamping plate 221 to move, and the clamping plate 221 moves toward the two ends of the vertical plate 2121, and the compensation block 002 is separated from the vertical plate 2121 and placed in the groove of the fiber blanket 001.

It should be noted that the shape of the compensation block 002 needs to fill the groove portion of the fiber blanket 001 .

It is worth mentioning that the thickness of the vertical plate 2121 on the upper fixing plate 212 should not be too thick to prevent a large gap from being formed between the compensation block 002 and the fiber blanket 001 after the vertical plate 2121 is moved out.

Further, as shown in Figure 7, the coating mechanism 3 includes a first coating roller 31 and a second coating roller 32 arranged below the fiber blanket 001, a turning frame 33 for fixing the first coating roller 31 and the second coating roller 32, a collecting trough 34 rotatably connected at both ends of the turning frame 33, a ratchet 35 arranged on the outside of the collecting trough 34 and fixedly connected to the turning frame 33, a telescopic rod 141 fixedly connected below the collecting trough 34 and used for driving the collecting trough 34 to move up and down. A second electric cylinder 37 fixedly connected to the first electric cylinder 36 by the telescopic rod 141 and used for driving the first electric cylinder 36, and a second rack 38 arranged on both sides of the second electric cylinder 37 and located on the moving path of the ratchet 35.

In this embodiment, a flip frame 33 and a ratchet 35 are provided to cooperate to complete the coating work of the arched parts at both ends of the fiber blanket 001. Due to the existence of the lower fixed plate 211, the coating mechanism 3 cannot complete all the coating work at one time, and the flip frame 33 needs to cooperate with the lower fixed plate 211 to complete the overall coating.

In detail, the first electric cylinder cooperates with the second electric cylinder 37 to drive the collecting tank 34 to move. At this time, the first coating roller 31 is located at the top to coat the middle part of the fiber blanket 001. After the coating is completed, the first coating roller 31 withdraws. During the withdrawal process, the ratchet 35 engages with the second rack 38. At this time, the ratchet 35 starts to transmit, realizing the flipping of the flip frame 33, and rotating the second coating roller 32 to the top for secondary coating.

It should be noted that the first coating roller 31 and the second coating roller 32 are located on both sides of the turning frame 33. The turning frame 33 is rotated to realize alternating operation between the first coating roller 31 and the second coating roller 32, one coating the middle of the fiber blanket 001 and the other coating the two sides of the fiber blanket 001. At the same time, in order to improve the coating effect and avoid dead corners without coating, a partial overlapping area should be set between the first coating roller 31 and the second coating roller 32.

By coating the continuous arcuate part of the fiber blanket 001 with a protective layer, the anti-oxidation ability of the fiber blanket 001 is further improved. At the same time, the protective layer can be made of polyvinyl chloride, silicone rubber and other ingredients. Because this kind of material is resistant to high temperature and corrosion and has a certain shape after solidification, it can adapt to the compression and release process faced in subsequent processing and use, avoiding cracks on the surface.

It is worth mentioning that while the second coating roller 32 is coating both sides of the fiber blanket 001 , the lower fixing plate 211 moves toward the middle of the fiber blanket 001 to prevent the lower fixing plate 211 from affecting the coating work of the second coating roller 32 .

Further, as shown in Figures 8, 14, 15, 16 and 17, the assembly mechanism 4 includes a bending piece 41 for bending the two ends of the fiber blanket 001 and an assembly 42 for assembling the folding module, the bending piece 41 includes a lifting plate 411 arranged below the fiber blanket 001 and driven by a telescopic cylinder to move up and down, a pressing plate 412 arranged on both sides below the two ends of the fiber blanket 001, an extension frame 413 fixedly connected to the lifting plate 411, a rotating shaft 414 rotatably connected to the extension frame 413, a linear slide rail 415 fixedly connected to the rotating shaft 414, a fixing groove 416 driven by a linear motor to move on the linear slide cabinet and used to fix the pressing plate 412, a second gear 417 fixedly connected to the rotating shaft 414, and a third rack 418 fixed to the frame and located on the moving path of the second gear 417.

In this embodiment, the fixing groove 416 and the rotating shaft 414 are provided to realize the 90° rotation of the pressing plate 412 , and the linear slide rail 415 is used to facilitate the movement of the pressing plate 412 , so that the pressing plate 412 can be quickly fixed and released.

In detail, after coating is completed, the lifting plate 411 rises and contacts the lower part of the fiber blanket 001. Driven by the linear motor, the fixed groove 416 moves and inserts the pressing plate 412 into the grooves of the fiber blankets 001 at both ends. Then the lower fixed plate 211 and the upper fixed plate 212 are both separated from the fiber blanket 001. At this time, the electric clamp 121 releases the fiber blanket 001, and the lifting plate 411 drives the fiber blanket 001 to move downward. During the downward movement, the second gear 417 engages the third rack 418, and the second gear 417 drives the linear slide rail 415 and the pressing plate 412 to rotate, so that the fiber blankets 001 at both ends rotate from the horizontal direction to the vertical direction, and at the same time fit in the middle of the fiber blanket 001.

It should be noted that, in the entire shaping process, both ends of the fiber blanket 001 were in a horizontal state, and the angle was flipped by rotation.

It is worth mentioning that the compensation block 002 is further fixed inside the fiber blanket 001 by rotating the pressing plate 412 to prevent gaps from appearing in the filling of the compensation block 002 .

Further, as shown in Figure 8, the bending member 41 also includes a first bevel gear 419 fixedly connected to both sides of the lifting plate 411, a threaded rod 420 rotatably connected to the inside of the fixing groove 416 and threadedly connected to the pressure plate 412, and a second bevel gear 421 fixed on the threaded rod 420 and capable of meshing with the first bevel gear 419.

In this embodiment, the threaded rod 420 , the first bevel gear 419 and the second bevel gear 421 are provided to realize the movement of the pressing plate 412 , and further the protruding portion of the fiber blanket 001 is compressed and further shaped by the movement of the pressing plate 412 .

In detail, when the pressure plate 412 moves into the fiber blanket 001, the first bevel gear 419 meshes with the second bevel gear 421. When the fixing groove 416 rotates, the second bevel gear 421 rotates relative to the first bevel gear 419, thereby causing the second bevel gear 421 to rotate, driving the threaded rod 420 to rotate, and the pressure plate 412 threadedly connected to the threaded rod 420 moves. Adjacent pressure plates 412 are grouped in pairs and approach each other to compress the protruding part of the fiber blanket 001.

It should be noted that the compression of the continuous arched protruding parts at both ends of the fiber blanket 001 is beneficial to the subsequent installation process. After the two fiber modules are installed, the wooden board 003 is pulled out. At this time, the fiber blanket 001 loses the compression and is released outward, and the two are engaged with each other, thereby realizing the effect of vertical force.

Further, as shown in FIG. 9 , the assembly 42 includes a mechanical gripper 422 for grabbing the bow-shaped wooden board 003 , a third electric cylinder 423 for pushing the fiber blanket 001 for compression, and a baler 424 for baling the compressed fiber blanket 001 .

In this embodiment, by providing the mechanical clamp 422 and the third electric cylinder 423, the steps of assembling, compressing and bundling the last wooden board 003 of the fiber blanket 001 are realized to form a finished ceramic fiber folding module.

In detail, the mechanical gripper 422 grabs the continuous bow-shaped wooden board 003 and places it at both ends of the fiber blanket 001. The third electric cylinder 423 is used to compress the fiber blanket 001 as a whole, and the fiber blanket 001 is bundled after the compression is completed.

It should be noted that, after the wooden board 003 is attached to the surface of the fiber blanket 001 , the pressing plate 412 is separated from the fiber blanket 001 to both sides, so as to avoid interference of the pressing plate 412 with the compression stroke of the fiber blanket 001 .

It is worth mentioning that the thickness of the pressing plate 412 is relatively small. Through the setting of the pressing plate 412, the wooden board 003 can be easily attached to the surface of the fiber blanket 001, and at the same time, it is avoided that after the pressing plate 412 is pulled away, a large space is left for the fiber blanket 001 to release the pressure.

Further, as shown in FIGS. 10-17 , the working process of the ceramic fiber folding module production device includes the following steps:

Step 1, folding step, fixing the two ends of the fiber blanket 001 on the electric clamps 121, the upper folding frame 13 and the lower folding frame 14 move towards each other, and folding the fiber blanket 001. During folding, the first guide rail 11 and the second guide rail 12 drive the two ends of the fiber blanket 001 to move in the horizontal direction and the vertical direction;

Step 2, forming and coating steps, one folding is completed, at this time, the middle part of the fiber blanket 001 is folded, the two ends of the fiber blanket 001 remain horizontal, and a compensation block 002 is set in the middle of each group of vertical plates 2121 in the upper fixed plate. The upper fixed plate 212 moves down, and the two ends of the fiber blanket 001 present a continuous arch shape when cooperating with the lower fixed plate 211. During the downward movement of the upper fixed plate 212, the gear rack drives the card plate 221 to move, so that the compensation block 002 is separated from the vertical plate 2121, and the compensation block 002 is filled into the space where the upper fixed plate 212 moves down. In the formed groove, the first electric cylinder 36 and the second electric cylinder 37 drive the first coating roller 31 to move at the same time, and the first coating roller 31 applies a protective layer to the middle of the compensation block 002. After the coating is completed, the first coating roller 31 withdraws, and under the action of the gear rack, the flip frame 33 rotates, the second coating roller 32 moves up, and the first coating roller 31 moves down, waiting for the coating in the middle of the fiber blanket 001 to solidify, and the lower fixed plate 211 moves toward the middle of the fiber blanket 001. At this time, the first electric cylinder 36 and the second electric cylinder 37 drive the second coating roller 32 again to apply a protective layer to both sides of the fiber blanket 001;

Step 3, compression step, after coating is completed, the lifting plate 411 moves up, the pressing plate 412 is stuck in the protrusions at both ends of the fiber blanket 001, the lower fixed plate 211 moves outward and separates from the fiber blanket 001, and the lifting plate 411 moves down. During the downward movement, driven by the gear rack, the linear guide rail 415 and the fixed groove 416 rotate to rotate the horizontal continuous arc to the vertical direction, and at the same time drive each group of pressing plates 412 to approach each other to compress the protrusions of the fiber blanket 001;

Step 4, assembly step, after the fiber blanket 001 is formed, the mechanical clamp 422 clamps the continuous bow-shaped wooden board 003, and inserts the wooden board 003 into the two ends of the fiber blanket 001. The fixing groove 416 moves on the linear slide rail 415 to move the pressing plate 412 out of the fiber blanket 001. The third electric cylinder 423 pushes the fiber blanket 001 for overall compression, and the fiber blanket 001 is bundled and fixed by the baler 424, and the production is completed.
