Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a retention cleaning device for fabrics developed to be able to effectively wash fabrics under the following conditions.

[Conventional technology]

There are a wide variety of devices for continuously washing industrially produced long fabrics, and the present inventor has developed various types of washing devices for cleaning effectively while conserving water resources. is being developed.

Conventional fabric cleaning equipment of this type has a large number of cleaning tanks, uses a large amount of water and hot water, and prolongs the contact time between the water and hot water to clean the fabric. However, such cleaning methods have many inconveniences, such as consuming a large amount of water, which goes against current water resource conservation efforts, and requiring a large equipment area due to the installation of many cleaning tanks. there were. In order to eliminate this inconvenience, a large number of guide rolls are installed in the washing tank for washing this type of fabric, and the fabric is repeatedly washed in eight meandering rows by being guided by these guide rolls. A method has been proposed in which the material is soaked in a liquid and subjected to a liquid-impregnating treatment.

[Problem to be solved by the invention]

Such a cleaning device has a complicated structure and also has the problem of high cost. Furthermore, in a cleaning structure in which the fabric is repeatedly immersed in a liquid while being guided by guide rolls, when the fabric is repeatedly pulled up from the liquid into the air while being guided by guide rolls, small wrinkles occur in the vertical direction due to the tension of the fabric. This was likely to occur and was a factor in deteriorating processing quality.

Also, cleaning water cannot enter the chemicals and glues that are trapped between the woven and knitted fabrics due to the tension caused by feeding the cloth unless the tension is loosened (shake the towel in water while wringing it out). The dirt will not come off).

(Means for Solving the Problems) The present invention has been made in view of the above, and its first aspect is
The purpose of this is to feed the fabric together with water into the recess of the rotating drum, which has approximately the lower half immersed in the washing tank and has a recess formed on the circumference for loading the fabric, so that the fabric can be freely transported. By increasing the amount of fabric feed relative to the width of the fabric, the fabric forms small loops and can be shaken off and piled up in layers. The purpose of the present invention is to increase the uniformity and reliability of cleaning by increasing and uniformly increasing the contact area of the fabric deposited on the cleaning water with cleaning water.

The second purpose is to self-circulate the self-cleaning water in the liquid tank and bring a portion of the self-circulating liquid into contact with the air-transferred fabric to perform effective cleaning while conserving water resources. .

〔Example〕

The present invention will be explained in detail below based on embodiments shown in the drawings.

In FIG. 1, 1 is a cylindrical drum made of a liquid-permeable plate such as wire mesh or punched metal, and the drum 1 is fixed to a horizontally positioned rotating shaft 2. The second rotation of the rotation shaft causes rotation of the second rotation axis. On the peripheral surface of the drum 1, dividing walls 3 protruding in the radial direction are provided at equal intervals in the circumferential direction, and a fabric stacking section 4 is formed between the dividing walls 3. Reference numeral 5 denotes a liquid tank receiving washing water 6, and substantially the lower half of the drum 1 is immersed in the washing water 6. 7 is a plate material such as a rope or punched metal that is curved into a substantially semicircular shape, and is fixed so that a slight gap is maintained so that the tips of the partition walls 3 that rotate together with the drum do not come into contact with each other. It is a guide plate. Reference numeral 8 denotes a fabric folding plate which is swingably supported around a support shaft 9, and this swinging plate 8 is swung in a pendulum shape via a connecting punch 11 by rotation of a crank disk 10. It is something. Reference numeral 12 denotes an overflow tank which is provided on the top of the folding plate 8, and which is placed oppositely to the front and back sides of the fabric to be transferred, and the washing water overflowing from this overflow tank 12 is It is designed to flow down onto the folding board 8. The wash water supplied to the overflow tank 12 is the wash water 6 in the liquid tank 5 that is pumped up by the pump 13.

14 is a new water supply pipe through which the appropriate amount is supplied at the appropriate time; 15 is a pump for supplying overflow water from the liquid tank 5 to the next tank; and 16 is a pump that heats the cleaning water in the liquid tank 5 to, for example, 85° C. or higher. heating pipe 17 for heating the fabric 18
19 is a spreading device, and 20 is a cloth pulling roll.

The configuration of this embodiment has been described above, and its operation will be described next. First, the cleaning water 6 is supplied into the liquid tank 5, and the cleaning water 6 is heated to about 80° C. or higher using the heating vibrator 16. Therefore, when feeding the fabric 18 into the liquid tank 5, the liquid! f
15 is supplied into the overflow tank 12, and the washing water is constantly allowed to flow down (overflow) from the overflow 4!12, so that the fabric 18 is dropped onto the folding plate 8 together with the flowing washing water. Ru. At this time, if the folding plate 8 is vibrated from side to side in the drawing, the fabric 18 will be transferred to the dividing wall 3 of the drum 1 along with the washing water.
It is swung upwards. By being shaken off together with the washing water, the fabric bends freely, and by feeding a large amount of fabric 18 with respect to the swing width of the folding plate 8,
As shown in the figure, they are folded and stacked many times in the shape of small sea urchins. When the amount of folding reaches a predetermined amount, the fabric is folded into the adjacent fabric stacking section 4 shifted by a -pitch due to the action of the controller. In this manner, fabrics are sequentially deposited in a folded state in the fabric depositing portion 4 formed on the peripheral surface of the drum 1, and when the accumulated fabrics pass through the washing water in the liquid tank 5, the fabrics are deposited as shown in the figure. 18 floats toward the dividing wall 3 and the drum 1 due to its buoyancy, and while maintaining a gap with the guide plate 7, the gap formed by the small loop contains enough cleaning water, and the cleaning water reaches between the woven and knitted structures. Drugs that will be filled and narrowed in the woven tissue,
Gluing agents and the like swell and are washed off and washed by the circulating flow of washing water.

FIG. 2 shows another embodiment of the invention. That is, in this embodiment, the fixed guide plate 7 in the previous embodiment is
This is replaced with an endless mesh conveyor 21 that rotates synchronously with the drum 1. Therefore, according to this embodiment, since the mesh conveyor 21 is rotated together with the drum 1, the fabrics deposited on each fabric stacking section 4 of the drum 1 are prevented from rubbing against the mesh conveyor 21. Therefore, damage to the fabric 18 and uneven processing can be effectively avoided.

The key point in each of the above embodiments is that the fabric 18 that is about to be deposited in the fabric stacking section 4 of the drum 1 is shaken onto the folding plate B together with the washing water under the downward action of the washing water overflowing from the overflow tank. The fabric may slide down and be folded into the fabric stacking section 4. That is, when the fabric 18 receives the overflow water, a pre-washing effect is produced on the fabric, thereby increasing the cleaning effect. In addition, the fabric becomes hydrated by receiving the overflow water, and the weight of the fabric increases and the fabric falls smoothly on the folding plate 8, so that the fabric is folded in an orderly manner in the fabric stacking part 4 of the drum 1. Therefore, the fabric is uniformly washed over the entire surface of the fabric in the liquid tank 5. In addition, the fabrics that are being folded in the fabric stacking section 4 are folded with sufficient overflow water, and the washing water is sufficiently interposed between the fabrics, resulting in close polymerization of the fabrics and poor cleaning. Problems such as the formation of parts can also be resolved. Furthermore, since the cleaning water supplied to the overflow tank 12 is the one that self-circulates the water in the liquid tank 5, the amount of water used can be significantly reduced.

(Effects of the Invention) As described above, according to the present invention, since self-circulating water is used, effective cleaning can be performed while saving water resources. In addition, since the fabric slides on the folding plate 8 together with the flowing water and is folded and supplied to the fabric stacking section 4 of the drum 1, the fabric sliding on the folding plate 8 smoothly descends into the fabric stacking section 4. The folding state becomes orderly,
Furthermore, when the fabric is deposited, by folding it into a large wave while producing small unibubs, the contact between the fabric and the washing water is increased, which makes the washing uniform over the entire surface of the fabric and improves the quality of the washed fabric. This has the effect of making improvements possible.
