Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid flow treatment device for fabrics, and more specifically, a liquid flow treatment device for fabrics in which a squeezing means is built into a circulation treatment passage formed by a retention tank and a transfer passage. Regarding equipment.

Conventionally, in liquid flow processing equipment for endlessly connected fabrics, water washing after processing steps such as scouring and dyeing is performed by draining the residual bath, filling the equipment with clean water, and circulating it using a pump. However, this was done by replacing the treated residual bath impregnated into the fabric with clean water and discharging the contaminated liquid from an overflow pipe provided in the upper part of the apparatus.

However, the water washing process using such a processing apparatus requires a long time to completely remove the treatment residual bath impregnated into the fabric, and is extremely inefficient.

The present invention provides a liquid flow treatment device in which a squeezing means capable of increasing the water washing efficiency is built into the circulation processing passage of the device in order to shorten the time required for the water washing process in such a liquid flow treatment device. It is something.

That is, according to the present invention, a circulation treatment passage is formed by a retention tank and a transfer passage, and the endless fabric swimming in the treatment liquid in the retention tank is treated in the retention tank upstream of the transfer passage. A liquid flow treatment device for fabric is provided, in which the fabric is lifted from the liquid level, moved through the transfer passage together with the treatment liquid supplied from the nozzle, and then circulated from the retention tank population section back into the retention tank for treatment. This device is characterized in that a pair of rollers are provided upstream of the nozzle after the fabric is pulled up, and the fabric is squeezed by this.

In the apparatus of the present invention, if desired, a fabric feeding reel may be provided above the processing liquid level in the retention tank, upstream or downstream of the pair of rollers, so that the fabric is removed from the processing liquid level. It is possible to smoothly pull up the fabric and transfer it to the transfer path.

Further, it is preferable that the pair of rollers be configured to have a nip and a denip.

That is, in the apparatus of the present invention, the fabric is generally not passed through the nip formed by these rollers during normal processing steps such as scouring and dyeing, but is impregnated into the fabric during the washing process after those processing steps. In order to increase the efficiency of replacing the remaining processing liquid with clean water, it is preferable that the liquid be squeezed through this nip. It would be advantageous if it were released.

Hereinafter, preferred embodiments of the device of the present invention will be described with reference to the accompanying drawings.

In Figure 1, 1 is a retention tank installed almost horizontally, and 2
indicates a jacket section partitioned by nest plates 3, and 4 indicates a tapered entrance section.

An outlet section 5 of the retention tank 1 is provided with a header chamber 6 and a deliquid chamber I that communicate with each other in the vertical direction.

A driving cloth feeding reel 9 is installed in the header chamber 6 for vertically lifting up the cloth 8 and transporting it forward; The transferred fabric 8 is compressed, and the treatment residual bath impregnated therein is removed.

The upper roller of the pair of rollers 10 is connected with a cylinder 23 or similar driving means so as to be able to move up and down as desired, and is configured to be capable of nipping and denipping as desired.

Furthermore, a partition plate 11 is provided between the header chamber 6 and the deliquid chamber 7 in order to prevent the deliqed residual bath from mixing with the processing liquid in the retention tank 1. The drained residual bath is discharged from a pipe 13 having a drain valve 12.

A nozzle 14 serves as a main driving source for transporting the fabric 8, and impregnates the fabric 8 compressed by the pair of rollers 10 with a jet of clean water, thereby promoting the replacement of the treated residual bath with the clean water.

The fabric 8 sent out from the nozzle 14 is sent into the inlet portion 4 of the retention tank through the transfer passage 15.

On the other hand, the jacket part 2 of the above-mentioned retention tank has a suction pipe 16
are in communication with each other, and the processing liquid or clean water is sent to the nozzle 14 via a pump 17 and a heat exchanger 18.

In addition, 19 is a regulating valve, 20 is a nozzle valve, 21 is a water supply valve, and 22 is a drain valve.

According to an example of the apparatus of the present invention configured as described above, during the scouring and dyeing processes, the upper roller of the roller pair 10 is raised by the cylinder 23 to release the nip (that is, denip). The operation is performed.

Next, when this scouring or dyeing process is completed, the residual bath in the apparatus is discharged to the outside from the drain valve 22, and then clean water is supplied through the water supply valve 21.

Next, a water washing process is performed, in which case the cylinder 23 lowers the upper roller to nip the pair of rollers 10, and the fabric 8 passing through this is squeezed to remove liquid.

The squeezed fabric 8 is impregnated with clean water by the nozzle 14, and the treated residual liquid contained in the fabric 8 is efficiently replaced with the clean water.

Another example of the device of the invention is shown in FIG.

In the embodiment shown in FIG. 2, the retention tank 1 is provided above the transfer passage 15 and is slightly inclined so that the depth of the processing liquid increases at the outlet.

In the header part 6, a pair of rollers 10 is provided above the surface of the processing liquid, and then a reel 9 is provided upstream thereof.

The fabric 8 that has passed through this reel is transferred into the transfer passage by a liquid flow from a nozzle 14 provided directly below the reel 9.

In this example, three suction pipes 16, 16a and 15b are provided, and each has a regulating valve 19, 19a and 19b.
is attached.

Also in this embodiment of the apparatus, extremely efficient water washing treatment is possible as in the above-mentioned apparatus.

According to the apparatus of the present invention as described above, the treated fabric can be washed with water extremely efficiently, and therefore the washing processing time can be significantly shortened.

For example, with the apparatus exemplified above, the time for washing with water after dyeing can be reduced to about 1/2 in all cases, and the amount of water required can also be reduced to about 1/2.
