Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an inner tank for treating textile materials, which is used when scouring, bleaching, dyeing, washing, and other treatments are applied to textile materials.

[Conventional technology]

As shown in FIG. 8, fiber materials such as gauze are usually received in the form of strips folded to a predetermined width and formed into square shapes, and then supplied to various processing steps such as scouring and bleaching. Such processing of fibrous materials has conventionally been carried out by filling a vertical cylindrical inner tank with the fibrous material and loading the fibrous material into a vertical cylindrical processing tank. That is, first, a rectangular fiber material (see Fig. 8) is folded into a ball, and then, as shown in Fig. 9, it is placed inside a cylindrical inner tank 1 with circulation holes formed on the bottom and side surfaces. Fill it in concentric circles. 3 is the rolled fiber material. The above-mentioned filling operation is usually performed manually by an operator. The inner tank 1 filled with the fiber material 3 in this way is then transformed into a processing tank 4 as shown in FIG.
The fibrous material is processed by loading the fibrous material into a container and circulating the processing fluid in the direction of the arrow. 5 is a pump for circulating processing fluid, and 6 is a coil type heat exchanger attached to the bottom of the processing tank 4.

[Problem that the invention attempts to solve]

However, when the cylindrical inner tank 1 is used, the fiber material 3, which is originally folded into an angular shape, must be folded into a round shape as described above and filled into the inner tank 1, which causes wrinkles in the fiber material 3. It has the disadvantage that it occurs in large numbers. In addition, the filled fiber material 3
Since the fiber density in the gaps between the clumps is small and there is little resistance, the processing fluid flows through these gaps more than other parts, and the processing fluid does not flow through the fiber material 3 sufficiently, causing uneven processing. I was getting used to it. Therefore, several proposals have been made to prevent the above-mentioned uneven processing by improving the flow of processing fluid (for example, Japanese Patent Publication No. 51-23631).
Since both use the same vertical cylindrical inner tank 1 as in the past, there remains the problem of wrinkles and uneven processing of the fiber material 3 due to incompatibility between the shape of the fiber material 3 and the inner tank 1. Ta.

Furthermore, Japanese Patent Publication No. 31-1937 discloses the use of a rectangular wooden box with a drainboard attached to the bottom for simple bleaching of fibers such as threads and knitted fabrics. However, the above-mentioned processing box is not special at all, and is simply a device that is used to properly pack fibers and heat them with steam rising from below, so that the steam rising from below evenly coats the inside of the fibers. It has the disadvantage that it is difficult to pass through and tends to cause uneven processing.

This idea was devised in view of these circumstances, and eliminates wrinkles and gaps when filled with fiber material.
The object of the present invention is to provide an inner tank for processing fiber materials that does not cause unevenness due to a uniform flow of processing fluid.

[Means for solving problems]

In order to achieve the above purpose, the textile material processing inner tank of this invention is a processing inner tank used when performing scouring, bleaching, dyeing, washing, and other treatments on textile materials using circulating processing fluid. The circulating processing fluid is used to scouring, bleaching, dyeing, and
An inner tank for processing used when carrying out water washing and other treatments, which is rectangular as a whole and has partition plates that partition the inside of the inner tank in parallel, and has a plurality of rectangular spaces divided by the partition plates. In this method, blocks of fiber material formed into rectangular shapes can be stored individually in the same shape, and a flow hole is formed at the bottom of the inner tank, and the side surface is made non-porous so that the processing fluid can flow through in the vertical direction. In addition, the inner tank has a double-bottomed bottom portion and a header portion for preventing drifting.

[Effect]

In other words, the inner tank of this invention is designed to individually store lumps of fiber material formed into rectangular shapes in the same shape within a plurality of rectangular spaces divided by partition plates. The fiber material can be filled as is without folding it into a circle.
Even during processing, this state is maintained and there is no possibility of shifting from side to side. Furthermore, since the lump-like fiber materials are not forced into each other and pressed against each other, uniform density is maintained in all parts. Therefore, the fibrous material does not wrinkle during processing and the passage of the processing fluid is also uniform. In addition, a flow hole is formed only at the bottom of the inner tank so that the processing fluid flows through it in a vertical direction, and a header section is provided at the bottom to prevent uneven flow, so that the processing fluid does not flow inside the fiber material. The processing fluid flows vertically in a uniform laminar flow state, so that the flow of the processing fluid is not biased. Therefore, the rectangular fiber material stored as is can be processed uniformly, and wrinkles or uneven dyeing will not occur in the processed product. This is a major feature of this idea.

Next, a detailed explanation will be given based on an example of this invention.

〔Example〕

FIG. 1 is a longitudinal sectional view showing an embodiment of the inner tank for processing fiber materials of this invention, and FIG.
It is an A′ cross-sectional view. This inner tank 11 has a rectangular shape as a whole, and has a double bottom portion, and this portion serves as a header portion 19. A communication hole 20 is formed in the double bottom portion of the bottom portion, and the side portion is non-porous. In addition, partition plates 31 are provided at predetermined intervals in the inner tank 11, and a plurality of rectangular fiber materials 3 (see Fig. 8) are arranged in parallel in the same shape (5 pieces in the figure), individually. It is designed so that it can be stored in a partitioned state. Further, protrusions 21 and 21a extending in the horizontal direction are provided on the outside of the side surface portion. These protrusions 21, 21a are
This part is used to support the work when automatically transporting the inner tank 11, loading it into the processing tank, or taking it out. Note that 22 is a reinforcing rib plate. Furthermore, a stepped portion 11a for fitting with an inner tank holding lid, which will be described later, is provided at the upper part of the side surface of the inner tank 11.

Using the inner tank 11, the fiber material 3 can be treated, for example, in the following manner. That is, first, the square-shaped fiber materials 3 shown in FIG. 8 are filled in the inner tank 11 in parallel without further folding. FIG. 1 shows the state in which the fiber material 3 is filled. This inner tank 11 is loaded into a processing tank of a processing device separately developed by the present inventors. This state is shown in FIG. In addition, the figure shows a state in which four inner tanks 11 are stacked in two layers and arranged in two rows. In the figure, 10 is a horizontal cylindrical processing tank, with an opening/closing lid 10a provided at one end.
and an inner tank holder 12 on which the inner tank 11 can be placed. In addition, on the ceiling of the processing tank 10,
Two hydraulic cylinders 14 are disposed, and the rods 14a thereof move up and down toward the inner tank 11 within the processing tank 10. The above rod 14a
An inner tank holding lid 15 that can fit into the stepped part 11a of the inner tank 11 is attached to the tip of the inner tank 11, and a groove part (Fig. ) is provided so that the inner tank 1 and the inner tank holding lid 15 can be sufficiently fitted. In addition, the inner tank holding lid 15
A communication hole 15a is opened in the. On the other hand, on the bottom side of the processing tank 10, there is a first processing fluid inlet/outlet opening 16 that communicates with the bottom flow hole 20 of the inner tank 11.
A heat exchanger 18a provided outside the processing tank 10 and a processing fluid circulation via piping are provided. It is connected to 18.

The treatment of the fiber material 3 in the treatment tank 10 is performed, for example, as follows. That is, first, the hydraulic cylinder 14 is actuated to push the rod 14a downward, and the inner tank holding lid 15 is lowered to fit into the stepped portion 11a of the inner tank 11 to press the fiber material 3 and equalize its density. . This state is shown in FIG. The figure is a cross-sectional view taken along line B-B' in FIG. Indicates a pressed state. In this way, the fiber material 3 is
The fibrous material 3 can be processed by circulating the processing fluid in the direction of the arrow in a state in which the fiber material 3 is pressed.

The fiber material 3 treated in this manner is uniformly treated by the treatment fluid flowing through it in the vertical direction, and there is no uneven treatment. In addition, during processing, the bulk fiber material 3 is guided from the top, bottom, left and right directions while maintaining its square shape in the inner tank 11, so that it does not lose its shape and wrinkles due to the flow of the processing fluid. do not have. Therefore, there are no uneven processing or creases, which have been problems in the past. We can provide processed products of extremely high quality.

Note that the size of the inner tank 11 is appropriately set depending on how many fiber materials 3 can be stored therein. Therefore, when processing a large amount of fiber material 3 at once, the inner tanks 11 themselves may be stacked in two or three stages, or arranged in two or more rows, as shown in the above embodiment. Process it according to the state. When stacking in multiple stages, it is particularly important to provide a header portion 19 at the bottom of the inner tank 11 as in the above embodiment. That is, as the height of the fibrous material 3 increases, the flow rate of the processing fluid is more likely to be uneven, but due to the presence of the header portion 19, the processing fluid evenly flows to the upper fibrous material 3.

In this way, when stacking the inner tanks 11 in multiple stages, as shown in FIG. A rib 30a is provided on the side surface of the tank 11b.
It is preferable to provide a lip 30 thereto and attach the lip 30 thereto. In this way, even if the processing fluid flows as shown by the arrow, the tip of the lip 30 will be connected to the lower inner tank 11c.
Since the sealing rib 30b is pressed to maintain the sealed state, the processing fluid does not leak between the upper and lower inner tanks 11b and 11c, and a uniform flow of the processing fluid is maintained. Note that when the lip 30 is attached to the inner tank holding lid 5 as well, as shown in FIG. 6, the fitting portion between the inner tank 11 and the inner tank holding lid 15 becomes sealed.
The processing fluid does not leak and is effective.

Furthermore, as shown in FIG. 7, the flow holes 20 in the bottom of the inner tank 11 are non-porous in the portion that contacts the peripheral edge of the lump of fiber material 3, and the portion that contacts the inner side of the lump of fiber material 3. It is preferable that the arrangement is such that the communication holes 20 are formed in the. That is, since there is a tendency for a large amount of the processing fluid to flow at the peripheral edge of the mass of the fiber material 3, by doing so, the flow of the processing fluid in the vertical direction becomes more uniform.

[Effect of idea]

As described above, blocks of fiber material formed into rectangular shapes can be individually stored in the same shape within the plurality of rectangular spaces divided by the inner tank partition plates for fiber material processing of this invention. Because of the curved shape, the fiber material can be filled as is without having to be folded into a circle, and the shape is maintained during processing so that it does not shift from side to side. Furthermore, since the lump-like fiber materials are not forced into each other and pressed against each other, uniform density is maintained in all parts. Therefore, the fibrous material does not wrinkle during the treatment and the passage of the treatment fluid is also uniform. In addition, a flow hole is formed only at the bottom of the inner tank so that the processing fluid flows through it in a vertical direction, and a header section is provided at the bottom to prevent uneven flow, so that the processing fluid does not flow inside the fiber material. The processing fluid flows vertically in a uniform laminar flow, so that the flow of the processing fluid is not biased. Therefore, the rectangular fiber material stored as is can be processed efficiently and uniformly, and wrinkles and uneven dyeing do not occur in the processed product.
