[0001]

[Industrial applications]

 The present invention relates to the improvement of a static mixing module used in an apparatus for contacting, mixing and dispersing two or more kinds of fluids (gas, liquid, powder, etc.) in a pipe flow path.

[0002]

[Background of device]

 The static mixing module is one or more statically placed in a tube with a predetermined length and inner diameter, and contacts, mixes, and disperses the fluid (gas, liquid, powder, etc.) flowing into this tube. It has a function of accelerating the above, and also has a function of mixing minute bubbles into the liquid in gas-liquid mixing.

Conventionally, a static mixing module as shown in FIG. 7 has been known. In the case of manufacturing the static mixing module having the structure shown in FIG. 7, conventionally, as shown in the left diagram of FIGS. 8 to 10, a piece (wing portion) having a predetermined shape is formed by pressing, and this piece is welded. After assembling it into a block as shown in the right figure, this block was further assembled into the structure shown in FIG.

In the above-mentioned independent piece forming method, since the block formation and the assembly accompanying the welding work are complicated, as shown in FIG. 11, the plate material 50 (blank) is pressed to cut the line 51 and the hole 53. To form. Reference numeral 52 is a twisted and raised portion. Then, after the press working, the block is formed by bending and twisting to form as shown in FIG. 12, or the two blades of the block shown in FIG. 12 are cut to form the blocks shown in A and B of FIG. Then, an improvement was made in which these were assembled into a static mixing module having the structure shown in FIG.

In the former case, the molding of the piece can be performed only by punching and pressing, and the pressing die can be simplified, and the accuracy as a single component can be easily secured. On the other hand, the static mixing module is used. It requires an extremely large number of parts in order to accommodate the piping dimensions that store the parts, and it is difficult to select and complement the parts, which not only causes quality control problems such as mixing of different products, but also the production cost and production efficiency. There was a big problem in terms.

In the latter method, the number of welding and assembly steps can be significantly reduced, but the press work requires a wide variety of blanks, holes, cuts, primary bending, twisting, and cut-offs, and requires many molds. Not only leads to an increase in production cost, but also not only causes deterioration in the strength of the twisted portion, but in some cases, high quality defects such as breakage, deformation, and burrs are high, making it difficult to handle. There was a drawback.

As is apparent from the above, the present invention aims to provide an improved static mixing module which is easy to mold and assemble and can be produced at low cost.

【Example】

 Next, a static mixing module according to the present invention will be described in detail according to an embodiment shown in the accompanying drawings.

In order to manufacture the static mixing module according to the present invention, first, the stainless steel plate 10 is punched by pressing according to the line shown by the solid line in FIG. At the same time or before and after, make a cut in the broken line portion 10A. The shape after punching is preferably an elliptical shape. Therefore, the predetermined punching may be performed after the stainless steel plate 10 is punched into an elliptical shape in advance, but the punching is preferably performed directly from the viewpoint of reducing the punching process.

By this punching, the intermediate strip 15 is left along the center line of the ellipse in the minor axis direction, and the intermediate strip 15 is orthogonal to the intermediate strip 15, that is, the ellipse having a constant width in the major axis direction. Wings 22, 23 and tails 24, 25 are left behind. Therefore, the wings 22 and 23 and the tails 24 and 25 are arranged on both sides of the intermediate strip 15. The wings and tail are arranged alternately from above. That is, the wings 22 and the tails 25 are alternately arranged on the right side of the intermediate strip 15. Further, the wings 23 and the tails 24 are alternately arranged on the left side of the intermediate strip 15. The length of the tails 24, 25 is not particularly limited, but it is preferably about half to 1/3 of the length of the wings 22, 23.

To manufacture the static mixing module according to the present invention, a bending process is performed next. This bending process may be performed simultaneously with the punching. Specifically, bending is performed according to the bending lines 15A and 15B indicated by the two-dot chain lines that define both sides of the intermediate strip 15 in FIG. That is, as shown in FIGS. 2 and 3, the wings 22 and 23 on both sides of the intermediate strip 15 are bent in the same direction with respect to the intermediate strip 15 at an angle of approximately 45 degrees, and the intermediate strip 15 is formed. The tail portions 25 and 24 on both sides of the intermediate strip 15 are bent at an angle of approximately 45 degrees with respect to the intermediate strip 15 in the direction opposite to the bending direction of the wings 22 and 23. Bending is performed in this manner to produce the mixing part material 20 shown in FIGS. The angle between the wings 22 and 23 and the tails 24 and 25 of the mixing part material 20 manufactured in this way is about 90 degrees (see FIG. 3 in particular).

By the bending as described above, as shown in FIG. 2, a gap 26 is formed between the wing portions 22 and the wing portions 22, or between the wing portions 23 and the wing portions 23.

In FIG. 1, reference numeral 21 is a linear support portion located at the tips of the tail portions 24, 25. The support portion 21 connects the wing portion 22 and the wing portion 22 adjacent to the wing portion 22 and functions as a reinforcement, but also functions as a stopper when the parts material 20 is assembled. Further, the function as the stopper can be achieved only by forming the convex portion on the wing portion 22 without forming the supporting portion 21 into a linear shape.

In order to manufacture the static mixing module 30 of the present invention using the part materials 20 as shown in FIG. 2, one set 20A and 20B of the plurality of part materials 20 is prepared as shown in FIG. The wing portions 22 and 23 are fitted to each other in the vicinity of the center of the corresponding gap 26 shown in FIG. Further, both the wing portions 22 and 23 are fitted to each other in the vicinity of the open end 26A of the gap 26 between the wing portions 22 and 22 formed by each of the pair of part materials 20A and 20B, and the inner part material Part material sets 20C and 20D are further formed outside the sets 20A and 20B. Specifically, as shown in FIG. 4, one part material set is formed of the part materials 20A and 20B, and a part material set is formed of the part materials 20A and 20D on one of the outer sides thereof, and the other of the outer side thereof is formed. A part material group is formed from the part materials 20B and 20C.

In this way, the static mixing module 30 as shown in FIG. 5 is obtained. Note that, in FIG. 5, the parts materials 20B and 20D are simply shown.

In the above-mentioned embodiment, it is preferable to weld the parts 20 and 20 to each other at several points, but it is not always necessary to weld them depending on the dimensional accuracy of the press work. The material of the module is not limited to the stainless plate material, and may be other metal or resin, ceramic, or the like. Plates are used for the wings and tail, but punch holes may be formed in such plates to further improve the mixing efficiency.

Further, although FIG. 1 shows a mode of punching into an elliptical shape, when assembled in the state of the module 30 shown in FIG. 5, the contour line is substantially a circle when viewed from the front of the figure. Assembly is performed so that This is a natural consequence of the fact that the static mixing module is usually arranged in a pipe having a perfect circular cross section, and when the pipe has a different shape other than a perfect circle, a corresponding shape is adopted.

In order to set the static mixing module 30 in the pipe, it is preferable to set a plurality of the static mixing modules 30 continuously and in close contact with each other with the front side of FIG. 5 facing upward. In this case, it is also preferable to rotate 90 degrees with the front side of FIG. 5 facing upward. In such a case, the tail portion 24A and the tail portion 25A can be cut from the bending line of the intermediate band 15 to facilitate the setting.

After the plurality of mixing modules 30 are continuously set in the pipe, it is preferable to weld the contact portions of the mixing modules 30 in order to prevent blurring due to fluid pressure.

Further, as shown in FIG. 6, a plurality of opposed intermediate strips 15 are provided with square through holes 35 without welding, and rods (not shown) which do not rotate after being attached to the through holes 35. It is possible to set a plurality of mixing modules 30 in the pipe by skewering (No.).

In the above embodiment, the tails 24 and 25 are bent at 45 degrees as shown in FIG. 3 so that the modules 30 can be arranged in an orderly grid as shown in FIG. Therefore, when such a lattice arrangement is not used, the tail portions 24 and 25 may not be bent at all, or may be bent at a slight angle. Further, the tails 24 and 25 may be twisted.

The size of the module 30 can be freely set by changing the lengths and widths of the wings 22 and 23 and the tails 24 and 25.

Further, when the required capacity of the static mixing module 30 is small, the tail portions 24 and 25 may not be provided. In such a case, one part material set may be formed from two part materials 20, and the static mixing module 30 may be formed by only one part material set. Also, one part material set is formed on the outside of the part material set (when there is no part material set formed of the part materials 20B and 20C on the other outer side in the above-described embodiment), and only that is set static. It may be the mixing module 30.

[0028]

[Effect of device]

 According to the present invention, it is possible to form a part material by performing a simple punching process and a bending process at least once by press working technology, and to manufacture a static mixing module by simply combining these parts. Since it can be manufactured, it can be manufactured at a much lower cost than conventional products, and it is also advantageous in terms of manufacturing cost and production efficiency.

Particularly, according to the first aspect of the invention, it is possible to perform mixing by combining the mixing unit materials of the minimum unit, and it is suitable when high mixing performance is not required. Further, according to the invention of claim 2, there is a possibility that a mixing performance higher than that of the above aspect can be obtained by providing not only the wing portion but also the tail portion. Further, according to the invention of claim 3, the tail portion is also provided. Bending at an angle of approximately 45 degrees with respect to the intermediate strip in the direction opposite to the bending direction of the blades can provide an orderly grid-like space, and higher mixing performance than the invention of claim 1 can be obtained. According to the invention of claim 4, there is a possibility that a higher mixing performance than that of the invention of claim 1 can be obtained by combining a plurality of parts materials.

However, in order to accommodate the dimensions of the pipes that house the static mixing module, an extremely large number of parts are required, and it is difficult to select and complement the parts. There were major problems in terms of production cost and production efficiency.

In the latter method shown in FIGS. 11 to 13, the man-hours for welding and assembling can be remarkably reduced, but the press working involves a wide variety of blanks, holes, cuts, primary bending, twisting, and cutting. Since many molds etc. are required, there is a problem that the production cost rises and the strength of the twisted part deteriorates, and there is a risk that the fracture rate, defective deformation, or burrs will increase. There was a problem that it was difficult to manage.

Further, in the above-mentioned aspect, it is particularly preferable that the tip of the tail portion has a linear support portion that connects the blade portions in parallel with the intermediate strip.

[0012]

【Example】

 Next, a static mixing module according to the present invention will be described in detail according to an embodiment shown in the accompanying drawings.

In order to manufacture the static mixing module of this embodiment, first, punching is performed by pressing according to the line shown by the solid line in the stainless steel plate 10 in FIG. At the same time or before and after, a scoring is made in the broken line portion 10A. The shape after punching is preferably an elliptical shape. Therefore, the predetermined punching may be performed after the stainless steel plate 10 is punched into an elliptical shape in advance, but the punching is preferably performed directly from the viewpoint of reducing the punching process.

By the above punching, the intermediate strips 15 are left along the center line of the ellipse in the minor axis direction, and the wing portions 22 having a constant width are provided on both sides of the intermediate strips 15, that is, in the major axis direction of the ellipse. , 23 and tails 24, 25 are left.

Further, a supporting portion 21 is defined at the tips of the tail portions 24, 25 by the above-mentioned scoring.

A gap 26 is formed at the tip of the tail portions 24, 25 or the support portion 21 by the punching.

The wing portion 22 and the tail portion 25, the wing portion 23 and the tail portion 24 are arranged on both sides of the intermediate strip 15, and the wing portion and the tail portion are alternately arranged from above. That is, on the right side of the intermediate strip 15 in the drawing, the wing portions 22 and the tail portions 25 are alternately arranged from above, and on the left side thereof, the tail portions 24 and the wing portions 23 are alternately arranged from above.

The length of the tail portions 24, 25 is not particularly limited, but it is preferably about half to 1/3 of the length of the wing portions 22, 23 at positions facing each other via the intermediate strip 15. This is for forming one side of the lattice of the part material after bending, which will be described later.

Next, bending processing is performed. This bending process may be performed simultaneously with the punching. Specifically, bending is performed according to a bending line indicated by a two-dot chain line that defines both sides of the intermediate strip 15 in FIG. That is, as shown in FIGS. 2 and 3, the wings 22 and 23 on both sides of the intermediate strip 15 are bent in the same direction with respect to the intermediate strip 15 at an angle of approximately 45 degrees, and the intermediate strip 15 is formed. The tail portions 25 and 24 on both sides of the intermediate strip 15 are bent at an angle of approximately 45 degrees with respect to the intermediate strip 15 in the direction opposite to the bending direction of the wings 22 and 23.

Bending is performed in this manner to manufacture the mixing part material 20 shown in FIGS. The angle between the wings 22 and 23, the tails 24 and 25, the wings 22 and 25, and the wings 23 and 24 in the mixing part material 20 manufactured in this way is about 90 degrees (particularly (See FIG. 3).

The supporting portion 21 defined in FIG. 1 is formed by punching, scoring, and bending as described above. The supporting part 21 functions as a reinforcement for connecting the wing part 22 and the wing part 22 adjacent thereto, and also plays a role of a stopper when the parts material 20 is assembled. In addition, when only the function as a stopper is required, the wing portion 22 may be formed with a convex portion.

In order to manufacture the static mixing module 30 using the part materials 20 shown in FIGS. 2 and 3, one set 20A and 20B of the plurality of part materials 20 is bent as shown in FIG. The wings 22 and 23 are fitted into the corresponding gaps 26 (see FIG. 2) so as to face each other, and are fitted until they come into contact with the support portion 21. Further, both of the wing portions 22 and 23 are fitted into each other near the open end 26A of the gap 26 between the wing portions 22 and 22 formed by each of the pair of parts materials 20A and 20B, and as shown in FIG. Form a grid.

That is, as shown in FIG. 4, part material sets 20C and 20D are further formed on the outer sides of the inner part material sets 20A and 20B. In other words, the part materials 20A and 20B form one part material set, the part materials 20A and 20D form the part material set on one of the outer sides, and the part material groups 20B and 20C form the part material set on the other outer side. Is forming.

In this way, the module 30 as shown in FIG. 5 is obtained. Note that, in FIG. 5, the part materials 20B and 20D are simply shown.

In the above embodiment, it is preferable to weld each part material at several points, but it is not always necessary to weld it depending on the dimensional accuracy of the press work. In either case, the number of welds is reduced compared to the conventional method in which all contact parts are welded.

The material of the module 30 is not limited to the stainless plate material, and may be other metal, resin, ceramic or the like.

Although plate members are used for the wings and tails, punch holes may be formed in the plate members in order to further improve mixing efficiency.

Further, FIG. 1 shows a mode of punching into an elliptical shape for the purpose of making the outer circumference of the part material 20 substantially circular. That is, since the parts material 20 has a substantially perfect circle, the assembled module (see FIG. 5) can be assembled so that the outline becomes a substantially perfect circle when viewed from the front of the figure, and the cross section has a perfect circle. Can be properly deployed in the pipe.

In order to set a plurality of the modules in the pipe, it is preferable that the front side of FIG. 5 is set in the pipe and each module is rotated 90 degrees and continuously set in a close contact state. .

In such a case, the tail portions 24A and 25A shown in FIG. 5 among the tail portions are cut off from the bending line of the intermediate strip 15 to facilitate setting of the adjacent modules.

Further, it is preferable to weld a plurality of adjacent modules at at least one contact portion after continuously setting a plurality of modules in a pipe, because the blur due to fluid pressure can be prevented.

Further, without welding, as shown in FIG. 6, a plurality of opposing intermediate strips 15 are provided with rectangular through holes 35, respectively, and non-rotating rods (not shown) are provided in the through holes 35. A plurality of the modules 30 can be set in the pipe by skewering. In this case, it is preferable that the modules 30 located at both ends are fixed by pressing.

The size of the module 30 can be freely set by changing the lengths and widths of the wings 22 and 23 and the tails 24 and 25.

In the above embodiment, the tails 24, 25 can be bent 45 degrees as shown in FIG. 3 to form the module 30 in an orderly grid arrangement as shown in FIG. Therefore, when such a lattice arrangement is not used, the tail portions 24 and 25 may not be bent at all, or may be bent at a slight angle. Further, the tails 24 and 25 may be twisted.

The above embodiment is an example of a static mixing module arranged in a pipe having a relatively large diameter. However, the static mixing module arranged in a pipe having a relatively small diameter is, for example, a tail portion in the above embodiment. It can be manufactured by adopting a mode in which 24 and 25 are not provided at all and a mode in which the number of wings 22 and 23 is reduced.

Although the embodiment of the present invention has been described above, the present invention can also be applied to a static mixing module for arrangement in a pipe having a large diameter other than the above embodiments.

[0037]

[Effect of device]

 According to the present invention, a lattice space having the intermediate strip and the wing portion or the intermediate strip, the wing portion and the tail portion as the sides is formed by the combination of the relatively short length of mixing part materials, and the adjacent wing portions are formed. Since a gap is formed between the blade and the blade, a complicated fluid flow path is formed, and as with the conventional module or packet, the mixing and stirring effect is high despite the relatively short length, and pressure loss is high. We can provide a small static mixing module.

Further, according to the present invention, it is possible to form a part material by performing a simple punching process and a bending process at least once by the press working technique, and the static mixing module can be formed only by combining the parts. Since it can be manufactured, it can be manufactured at a much lower cost than conventional products, and it is also advantageous in terms of manufacturing cost and production efficiency.

According to the first aspect of the invention, it is possible to perform mixing by combining a minimum unit of mixing part materials, which is suitable when high mixing performance is not required. Further, according to the invention of claim 2, there is a possibility that the mixing performance higher than that of the above aspect can be obtained by providing not only the wing portion but also the tail portion. Further, according to the invention of claim 3, The tail portion is also bent in the direction opposite to the bending direction of the wing portion at an angle of about 45 degrees with respect to the intermediate band, so that an orderly lattice-shaped space is obtained, and higher mixing performance than that of the invention of claim 1 is obtained. According to the invention of claim 4, there is a possibility that a higher mixing performance than that of the invention of claim 1 can be obtained by a plurality of combinations of parts materials.
