Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid stream treatment device. In particular, the present invention relates to a liquid treatment device for a long fiber cloth, which is provided with a mechanism for preventing the cloth from being twisted during processing.

[0002]

[Prior Art]

 A so-called liquid flow treatment device for laying a long fiber cloth into an endless rope and circulating both the cloth and the treatment liquid for liquid treatment is well known. In such a liquid flow treatment apparatus, the cloth is transferred by the jet stream of the processing liquid through the cloth transfer pipe connected from one end to the other end of the processing tank in which the cloth is temporarily retained, and is returned to the processing tank again. So that it is circulated and processed. This jet of the processing liquid is usually given by the processing liquid jetting unit provided at the outlet of the processing tank, but it is extremely difficult to uniformly jet the processing liquid from the processing liquid jetting unit, and in general, The resulting jet has a spiral shape, which causes a problem that the cloth is twisted. In particular, when two cloths are processed through one transfer pipe, the cloths are entangled with each other, and it is difficult to take them out from the apparatus after the processing, resulting in a large amount of labor and time. ..

[Problems to be solved by the device]

 An object of the present invention is to solve the problems of the related art. That is, an object of the present invention is to provide a liquid stream treatment device for a fabric, which can effectively prevent twisting of the fabric during treatment.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides an apparatus having the following configuration. That is, it includes a treatment tank for temporarily retaining the long fiber cloth, a transfer pipe connected from one end to the other end of the treatment tank, and a treatment liquid injection unit provided at the outlet of the treatment tank. An annular processing passage of the cloth is formed to circulate the cloth by the jet of the processing liquid by the processing liquid spraying section so as to return from the processing tank to the processing tank via the transfer pipe, while the processing liquid suction section of the processing tank pumps the cloth. A liquid flow treatment device for a fabric, wherein a treatment liquid circulation path is provided to reach the treatment liquid injection unit via a heat exchanger, and the fabric is treated while being transferred with the treatment liquid in the annular treatment passage. A liquid flow treatment apparatus for a fabric, wherein a plurality of protrusions extending in a longitudinal direction are provided on an inner peripheral surface of the pipe in at least a part of the transfer pipe.

[0005]

[Action]

 In the apparatus of the present invention having such a configuration, since the plurality of projections extending in the longitudinal direction are provided on the inner peripheral surface of the transfer pipe connected to the processing liquid ejecting section, the jet of the processing liquid from the processing liquid ejecting section is swirled. The twisting of the fabric due to the shape is effectively prevented in the transfer pipe. In the device of the present invention, the plurality of protrusions may be provided at one place or at several places in the entire length or a part of the transfer pipe. However, since this protrusion is for preventing twisting of the fabric due to the jet flow from the treatment liquid jetting section, it is generally preferable to provide it on the side of the transfer pipe near the treatment liquid jetting section. Let's do it. Further, the size and shape of the protrusion are arbitrary as long as the desired effect of preventing twisting is obtained.

【Example】

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

FIG. 1 is a side sectional view schematically showing an example of the liquid flow treatment apparatus according to the present invention. A transfer pipe 2 is provided outside the processing tank 1 so as to connect the outlet and the inlet, and inside the processing tank 1, the cloth 5 to be treated is treated with a bath of the processing liquid at the outlet. A cloth pulling reel 5 for pulling up from 4 and a treatment liquid ejecting section 3 for giving a jet of treatment liquid are provided. The cloth to be treated 5 slowly advances from the inlet of the treatment tank 1 to the outlet side while temporarily staying in the bath of the treatment liquid formed in the treatment tank, and the fabric pulling reel 6 causes the bath of the treatment liquid to flow. Then, it is drawn into the transfer pipe 2 together with the processing liquid by the jet flow of the processing liquid generated by the processing liquid injection unit 3, and is transferred so as to be circulated to the inlet of the processing tank 1 in the transfer pipe.

On the other hand, the treatment liquid is sucked from the treatment liquid suction portion provided at the bottom of the treatment tank 1, passes through the treatment liquid circulation passage 7 through the treatment liquid circulation pump 8 and the heat exchanger 9, and is then treated. It is sent to the injection unit 3. Then, in this processing liquid jetting section, it is turned into a jet flow and is sent from the transfer pipe 2 to the processing tank 1 to form a bath of the processing liquid in the processing tank.

Therefore, in this device, the cloth passing through the transfer pipe in the longitudinal direction according to the present invention, for example, on the inner peripheral surface of the portion 10 of the transfer pipe 2 on the side close to the treatment liquid ejecting unit 3. Is provided with a plurality of protrusions for preventing the twisting. That is, as shown in FIGS. 2A and 2B, four elongated projections 11 are formed on the inner peripheral surface of the transfer tube 2. 2A is a horizontal sectional view of the projection forming portion 10 of the transfer tube, and FIG. 2B is a vertical sectional view taken along the line AA of FIG. 2A. The protrusion forming portion 10 may be directly attached to the transfer tube, or may be detachably configured.
