Description

[Detailed description of the invention] [Industrial application field] This invention is used in dyeing equipment, particularly winch-type dyeing equipment, to remove fine fiber waste dispersed in the dye solution during dyeing.
The present invention relates to a dyeing device equipped with a filter for removing fuzz.

[Conventional technology]

In conventional dyeing equipment, a filter for removing fine fiber waste and fuzz from the dye solution is installed near the suction or discharge port of the dye solution circulation pump attached to the dye tank. In this case, negative pressure is applied at the suction port of the circulation pump and positive pressure is applied at the discharge port, so several bolts and nuts are used to securely tighten the filter, and bolts and nuts are used for each dyeing process. It is common practice to loosen the nut, remove the filter with fiber debris, etc., and replace it.

However, a dyeing machine in which the side plate of the dyeing tank was formed into a perforated plate and a winnowing board was installed inside this part was developed in 1973.
No. 37591 and Utility Model Publication No. 1986-8632 show a dyeing device in which two porous partition plates are installed in the main dye tank, but all of these are fixed in the dye tank and are integrated. Freedom to insert and remove the cage into the staining tank.
No consideration is given to the removal of attached fiber debris, and the filter is substantially different from the filter intended by this invention.

[Problem that the invention attempts to solve]

In conventional dyeing equipment, the filter is installed in a narrow space at the bottom of the dyeing tank due to its relationship with the circulation pump, which requires considerable effort and time to replace the filter, or when the dyeing equipment is operated. It was not possible to remove and replace it.
Furthermore, the size of the filter is also limited in relation to the thickness of the piping, and as a result, there is a limit to its filtration capacity.Therefore, it has been desired to improve workability when replacing the filter and to improve efficiency by expanding the filtration capacity.

[Means for solving problems]

The dyeing tank side plate on the passage side through which the dye liquor and the object to be dyed rise and move is formed into a porous surface, and a small casing is provided with a dye liquor circulation pipe connected to a dye liquor circulation pump connected to the outside of the porous surface. In a winch-type dyeing device in which the dye solution is introduced into the dyeing tank and sent to the circulation pump, a filter is inserted into the small housing, and the porous surface of the dyeing tank side plate and the filtration surface of the filter are arranged in a parallel relationship with each other. The dye liquor that has passed through the porous surface of the side plate of the dyeing tank is removed from fiber waste by a removably inserted filter, and then sent to the circulation pump.

[Function] The porous surface of the side plate of the dyeing tank prevents the objects to be dyed from moving toward the small casing due to the flow of the dye liquid as they move and disrupting the movement, and prevents the objects from flowing into the small casing. After the dye liquor is filtered to remove fiber waste, etc., it is sent to a circulation pump and circulated within the dye tank.

The filter inside the small casing is inserted into the guide rail and can be inserted into and removed from the small casing, so if the filtration efficiency decreases due to a large amount of attached fibers, etc., the filter can be removed from the small casing at any time. It can be removed and replaced.

〔Example〕

An embodiment of this invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a dyeing tank, and inside the dyeing tank 1, a sealed chamber is formed by an inner wall 2.

The inner wall 2 is formed to maintain an appropriate distance from the side plate 1a of the dyeing tank 1, and a passage 3 is formed between the inner wall 2 and the side plate 1a. 4 is a win roll which is actively rotated above the inner wall 2 by a motor (not shown).

The object to be dyed 5 is suspended on the win roll 4 with the window or door 6 opened, and both ends are sewn to allow the object to be dyed to pass through the passage 3, which is composed of the inner wall 2 and the side plate 1a of the dyeing tank 1, and run in an endless manner. do. That is, the object to be dyed 5 sent out by the win roll 4 slides on the guide plate 7 and falls into the passage 3,
It passes through the passage 3 while being deposited in a zigzag pattern, and finally runs while being pulled up towards the win roll 4, and as this process is repeated, it is dyed with the dye solution stored in the passage 3.

8 is a dye liquid circulation pump driven by a motor 9, and on the discharge side of the pump 8 there are pipes 10,
Dye liquid discharge pipe 1 via dye liquid heating heater 11
2 and 13 are connected, and the dye liquid sent out by the dye liquid circulation pump 8 is jetted into the passage 3 from nozzles provided in the dye liquid discharge pipes 12 and 13.
The side plate 14 of the dyeing tank 1 on the side where the object to be dyed 5 moves upward toward the win roll 4 has a porous surface with a large number of holes 15 at its lower part, and a dye liquid circulation pump is installed outside this part. A small casing 17 is connected to a dye liquid supply pipe 16 connected to a suction port of 8.

Guide rails 20 and 21, which extend from the top to the bottom of the small housing 17, are provided inside the front and rear surfaces 18 and 19 of the small housing 17, facing each other. The perforated surface of the side plate 14 of the dyeing tank 1 and the filtration surface 23 of the filter are positioned parallel to each other.

24 is a filter frame of the filter 22, 25 is a handle of the filter 22, and 26 is a lid that covers the opening of the small housing 17.

Therefore, the dye solution containing fiber waste separated from the object to be dyed 5 while flowing through the passage 3 flows into the small casing 17 from the porous surface of the side plate 14 of the dyeing tank 1, and is removed by the filter 22. After being removed, the dye is returned to the passage 3 of the dye tank 1 via the feed pipe 16 and the dye liquid circulation pump 8. When fiber debris etc. adhere to the filtration surface 23 of the filter 22 and the filtration efficiency decreases, open the lid 26 of the small casing 17, grasp the handle 25, pull up the filter 22, and insert a newly prepared filter. Just do it.

However, it is preferable that the size of the holes 15 provided in the side plate of the dyeing tank and constituting the porous surface is large enough to prevent fiber waste etc. in the dye solution from adhering, and the shape thereof is also arbitrary. It is also possible to change the filtration efficiency by increasing or decreasing the depth of the dye solution in the dyeing tank by changing the formation position of the porous surface, or by increasing or decreasing the area of the porous surface. .

Filter 2 used in the dyeing device of this invention
The filtering surface 23 of the filter 2 may be made of a fine mesh as shown in Figures 2 and 3, or may be a panel-like material made of a metal or plastic plate with many small holes. The frame of the filter 22 may be made of metal, hardened plastic, wood, etc., but in order to fit the filter 22 in a curved manner along the guide rails 20 and 21 as shown in Figure 1, it is appropriate that the frame 24 of the filter 22 be made of flexible rubber, plastic, thin metal material, etc.

In addition, as shown in FIG. 3, if a pin 27 is attached to the upper edge of the frame 24 and a sample piece 28 of the same type as the object to be dyed 5 is fixed to the pin 27, the dyeing apparatus can be stopped during staining. It is convenient to be able to inspect the progress of staining by pulling up the filter from within the small housing at any time. Alternatively, the pin 27 may be provided on the inner surface of the lid 26 of the small housing 17, and the progress of staining may be inspected by suspending the sample piece 28.

[Effect of idea]

In the dyeing apparatus of this invention, the dyeing tank side plate on the passage side through which the dye liquor and the object to be dyed rise and move is formed into a porous surface, and a dye liquor circulation pipe connected to a dye liquor circulation pump is provided on the outside of the porous surface. In a winch-type dyeing device that consists of connected small casings into which the dye solution flows and is sent to a circulation pump, a filter is inserted into the small casing and the porous surface of the dyeing tank side plate and the filtration surface of the filter are connected to each other. The filters are positioned parallel to each other, so even if the dyeing equipment is in operation, the filter can be easily pulled out from the small housing according to the adhesion state of fiber waste, etc., without stopping the operation. Moreover, it can be replaced quickly.

In addition, the porous surface of the side plate of the dyeing tank prevents the movement of the dyed object from being disturbed by the flow of the dye liquid flowing into the small housing from the dyeing tank, and allows for a smooth guide of the dyed object. However, by changing the formation position of the porous surface, the depth of the dye solution in the dyeing tank can be increased or decreased, or by increasing or decreasing the area of the porous surface, the filtration efficiency can be changed. has.

Furthermore, the opening of the small casing can be used as an inlet for dyeing aids or the like, or can be used to inspect the progress of staining using sample pieces.
