Description

[Detailed description of the invention]

[Field of Application of the Invention] The present invention is directed to reducing impurities such as glue and fiber waste attached to the surface of long fabrics such as woven and knitted fabrics by reducing the amount of water and thermal energy used, thereby saving resources and energy. This invention relates to a continuous cleaning device for fabrics that has been developed to be able to effectively remove and wash impurities under the conditions. [Background of the Invention] Immediately after pre-treatment such as burning, scouring, bleaching, etc. for long lengths of industrially produced fabric, and the printing treatment that follows the pre-treatment, the surface of the treated fabric is A cleaning process is required to remove attached impurities such as thread waste and printing paste. Conventional cleaning equipment used in this cleaning process uses cleaning water (hot water) as shown in Figure 2, for example.
20 and a large number of guide rolls 22 arranged in this washing tank 21 to repeatedly immerse the fabric in the washing liquid (hereinafter referred to as a conventional type). , since the textile fabric 23 to be washed after printing is guided by the guide rolls and is washed by a simple means of contact with washing water, which is repeatedly immersed in the liquid. The cleaning efficiency in each tank is low, so multiple cleaning tanks must be installed in advance, and large amounts of clean water must be sequentially supplied to these cleaning tanks, so a large amount of clean water is not consumed. Unavoidable, for example, the amount of fresh water used for washing after printing a kg of fabric (cotton fabric) is approximately
2.5 TON/H was consumed. In addition, as a water-saving cleaning device that is an improvement on this conventional type, for example, as shown in FIG. 25, and a guide roll 27 which is disposed within this rigid chamber 25 and transports the fabric 26 to be washed in a meandering manner from the bottom to the top.
and a guide roll 28 which is disposed in the liquid tank 24 and transports the fabric 26 in a meandering manner in the liquid.
There is also a washing device having a water supply pipe 29 for showering washing water from the ceiling of the vertical room 25 toward the fabric 26. In this water-saving type, part 1
Although the amount of fresh water for cleaning treatment per kg has been reduced to approximately 1.5 TON/H, even with these cleaning devices, the intended cleaning could not be performed unless a large amount of fresh water was consumed. However, due to the current shortage of water resources, efforts are being made to conserve washing water when washing fabrics or to reduce equipment costs for washing equipment, but current washing equipment has not been able to save washing water. In addition, the equipment cost increases due to the installation of multiple cleaning tanks, so a large amount of equipment cost and a large amount of water resources are consumed as usual. [Purpose of the Invention] The present invention has been made in view of the above, and it is possible to continuously wash the fabric by applying washing water to the fabric that is continuously run. In order to reduce consumption and perform cleaning effectively in a short period of time,
In the washing tank, the washing water is applied to the fabric while it is meandering from the bottom to the top. In addition to disposing respective nozzles for spraying cleaning water through each guide roll, a draining bar that comes into contact with the fabric drawn out from each guide roll is provided to ensure that the cleaning water applied to and impregnated with the fabric is replaced. To increase the speed and further provide a self-circulation path for jetting the water accumulated at the inner bottom of the washing tank from each of the nozzles, thereby effectively washing the transferred fabrics while conserving water resources. The purpose of this invention is to provide a continuous cleaning device for fabrics that can perform continuous washing of fabrics. [Embodiments of the Invention] The present invention will be described in detail below based on embodiments shown in the drawings. Reference numeral 1 denotes a liquid tank with an open top, and this liquid tank 1 is filled with cleaning water 2 (actually hot water heated to about 90° C.). Reference numeral 3 denotes a rigid chamber whose lower surface is open and whose opening diameter is smaller than the diameter of the liquid tank 1;
The lower opening edge of is immersed in the washing water 2 of the liquid tank 1, and the inside of the rigid chamber 3 is kept airtight. Inside the liquid tank 1, a large number of guide rolls 5 are arranged to move the fabric 4 in a meandering manner up and down. Further, inside the rigid chamber 3, a large number of guide rolls 6 for moving the fabric 4 in a meandering pattern from side to side are arranged in multiple stages up and down and in two rows on the left and right.
Furthermore, each liquid receiving tray 1 is provided below each guide roll 6.
7 are arranged. Reference numeral 7 denotes a cleaning shower nozzle for spraying cleaning water toward the fabric 4 that is brought into guide contact with each guide roll 6.
It is set up correspondingly. 8 is guide roll 6
A draining bar (draining roll) 9 for squeezing out the washing water that is impregnated into the fabric immediately after being drawn out is arranged approximately at the midpoint of both the left and right guide rolls 6,
It shows a beater that knocks off any remaining moisture from the fabric. Reference numeral 10 denotes an inlet for washing water countercurrent from the next tank, and this inlet 10 is provided on the ceiling of the vertical room 3. Reference numeral 11 designates a self-circulation circuit for spraying the cleaning water 2 in the liquid tank 1 from each of the cleaning shower nozzles 7 using the power of the pump 12;
A counter waterway is shown for supplying a part of the water to the front tank using the driving force of the pump 14. Reference numeral 15 denotes a pollution level sensor that detects the degree of pollution of the washing water 2 by introducing a part of the washing water 2 into the liquid tank 1, and detects the pollution level of the washing water 2 by detecting the pollution level of the washing water from the set value. If it is detected that the level of pollution is too high, the fresh water supply valve 16 is automatically opened to supply fresh water to a predetermined level of pollution. The above is the configuration of this embodiment. Next, the operation will be described. First, the fabric 4 to be washed is supplied into the liquid tank 1, and each guide roll 5 disposed in the liquid tank 1 is Therefore, the cleaning water 2 is transported in a meandering manner, and pre-washing is performed during this time. The fabric 4 thus prewashed in the washing tank 1 is guided by each guide roll 6 in the vertical chamber 3 and ascends while meandering from side to side within the vertical chamber. Since the impregnating action of washing water sprayed from the washing shower nozzle 7 and the squeezing action of the draining bar 8 are alternately repeated, the replacing action of the washing water impregnated into the fabric is significantly improved, making it extremely effective. Fabric cleaning effect can be obtained. Furthermore, in this embodiment, since the cleaning water jetted from each cleaning shower nozzle 7 is sprayed onto the fabric that is in guide contact with the guide roll 6, impurities on the surface of the fabric are removed by receiving the cleaning water spout. The relaxing effect of is also effective. Furthermore, since the beater 9 vibrates the fabric between the left and right guide rolls 6, it is effective in splashing off moisture contained in the fabric and impurities attached to the fabric surface. As a result, fabrics can be washed reliably and in a short time using an extremely small amount of water.
Further, in this embodiment, the cleaning water is self-circulated, and fresh water (clean water) is automatically supplied by the action of the sensor 15 and the solenoid valve 16 only when the degree of pollution becomes severe. As a result, a large amount of washable water can be brought into contact with the fabric 4 per unit time while reducing the amount of fresh water consumed. Therefore, since the amount of fresh water consumed can be reduced and the fabric can be washed effectively, water resources can be saved and the economical efficiency of fabric washing can be greatly improved. Furthermore, the action of the saucer 17 allows the washing liquid to flow down onto the fabric 4, thereby increasing the contact with the washing water. That is, the cleaning by the above-mentioned embodiment device carried out by the present inventor, and the cleaning tank by the conventional type and the water-saving type.
As a result of comparing the amount of heat and water used during cleaning,
As shown in the following comparative example, it can be seen that the cleaning device of the present invention is far superior.

[Table] [Summary of the Invention] As described above, the present invention includes a washing tank and a large number of guide rolls arranged in two rows in the vertical direction, which are provided above the washing tank and which transport the fabric in a meandering manner from the bottom to the top. In a cleaning device having a rigid chamber, a cleaning shower nozzle attached to each guide roll and a cleaning shower nozzle separated from each guide roll are used to spray cleaning water onto the fabric that is guided in contact with the guide rolls. In order to squeeze water out of the fabric immediately after, a draining means such as a roll or a bar is installed near the fabric lead-out portion of each guide roll, and a beater that excites the fabric extending between the left and right guide rolls to drain the water. , a self-circulation circuit for injecting the water in the cleaning tank from the cleaning shower nozzle, and detecting the degree of contamination of the water in the cleaning tank, and if the degree of contamination is equal to or higher than a standard value, the This is a continuous fabric cleaning device characterized by having a pollution level sensor for adding fresh water to a self-circulating circuit and a fresh water supply control means. [Effects of the Invention] Therefore, according to the continuous fabric cleaning device of the present invention, the fabric that is guided by each guide roll and sequentially ascends while meandering from side to side is subjected to the impregnating action of washing water sprayed from the washing shower nozzle. Since the liquid squeezing action and the squeezing action by the draining means are repeated alternately, the action of replacing the washing water impregnated into the fabric is significantly improved, and an extremely effective fabric washing effect can be obtained. Furthermore, in this invention, since the cleaning water jetted from each cleaning shower nozzle is sprayed onto the fabric that is in guide contact with the guide roll, the jetting force of the cleaning water is applied to remove impurities on the surface of the fabric. is also valid. Furthermore, since the beater vibrates the fabric between the left and right guide rolls, it is effective in splashing off moisture contained in the fabric and impurities attached to the fabric surface. Therefore, the cleaning of the fabric can be achieved reliably and in a short time using an extremely small amount of water. Furthermore, in the present invention, the cleaning water is self-circulated, and the turbidity sensor and fresh water supply means automatically supply fresh water (clean water) only when the pollution level becomes severe. Because of this, a large amount of washable water can be brought into contact with the fabric per unit time while reducing the amount of fresh water consumed. Therefore, since the amount of fresh water consumed can be reduced and the fabric can be washed effectively, water resources can be saved and the economical efficiency of fabric washing can be greatly improved.
