Description

Technical Field

[0001] The utility model belongs to the technical field of printing and dyeing equipment, and particularly relates to a drum-type water washing box with an overflow sewage discharge device for flat-width water washing of low-tension fabrics. Background Art

[0002] During the actual production process of the drum water washing unit used in the traditional flat-width printing and dyeing production line, especially when processing fabrics that generate a large amount of floating substances during certain processes, the drum water tank will become turbid in a short time. Moreover, due to the layout of the front and rear water separation plates, the floating substances are likely to stay on the water surface of the drum water tank and are difficult to be discharged in time, which reduces the water washing efficiency and makes the cleaning operation of the machine difficult. At the same time, the three drums of this traditional water washing unit are driven by the same driving power source, and the linear speed between adjacent drums is fixed. If the fabric elongates or shrinks during the fabric dipping and water washing process, the tension on the path will be失调, and even exceed the appropriate tension range. Summary of the Invention

[0003] The purpose of the utility model is to provide a drum-type water washing box with an overflow sewage discharge device that can timely discharge the floating substances in the water tank and maintain stable tension operation in view of the defects of the existing technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A drum-type water washing box with an overflow sewage discharge device includes an upper drum and two lower drums arranged in a "pin" shape in the box body. The characteristics are as follows: the two lower drums are respectively arranged in the drum water tank, and an overflow sewage discharge tank is arranged at the height position of the upper liquid surface of the drum water tank. The floating substances falling off after the fabric water washing float on the liquid surface and are discharged in time through the overflow sewage discharge tank, thereby ensuring the cleanliness of the water washing liquid and improving the water washing efficiency.

[0006] It is further characterized in that: the upper drum and the lower drums are both provided with independent transmission devices for adjusting the speed ratio between adjacent drums. When the fabric elongates or shrinks during the fabric dipping and water washing process, the speed ratio between adjacent drums is adjusted through the independent transmission device to keep the fabric tension stable and prevent the tension from being失调.

[0007] Furthermore: the overflow sewage discharge tank is connected to a filter, and the overflow water is filtered by the filter and recycled, thereby saving the water consumption of water washing.

[0008] Furthermore: the bottom of the drum water tank is connected to the filter through a drain pipe.

[0009] Furthermore: a plurality of spray pipes are arranged on both sides above the upper drum, and the water washing liquid filtered by the filter is sprayed out from the spray pipes and recycled.

[0010] Preferably, a cloth feeding and filament separating roller is arranged at the cloth feeding end of the water washing box, and the fabric is flattened before water washing.

[0011] Preferably, the shape of the drum water tank matches the shape of the fabric traveling track, reducing the consumption of water washing liquid and saving costs.

[0012] Preferably, a glass window is arranged on the water washing box for observing and monitoring the water washing process.

[0013] The utility model quickly clears the water washing shedding substances floating on the surface layer through the arrangement of the overflow sewage discharge tank, prevents the turbid water washing liquid from affecting the surface quality of the fabric, and improves the water washing efficiency. Through an independent drum driving device, the speed ratio between adjacent drums is adjusted to keep the fabric tension stable and prevent tension imbalance. Description of the Drawings

[0014] Figure 1 is a schematic structural diagram of the utility model. Detailed Embodiments

[0015] As Figure 1 shown, a drum type water washing box with an overflow sewage discharge device includes an upper drum 11 and two lower drums 4 arranged in a "pin" shape in a box body 1. The two lower drums 4 are respectively arranged in drum water tanks 6. Three spray pipes 10 are respectively arranged on both sides above the upper drum 11. A glass window 9 is arranged on the water washing box for observing and monitoring the water washing process. The upper drum 11 and the lower drums 4 are both driven to rotate by independent drum motors 2, and each drum motor 2 is independently controlled by a drum driving power supply 14. The shape of the drum water tank 6 matches the shape of the fabric 13 traveling track, reducing the consumption of water washing liquid and saving costs. An overflow sewage discharge tank 7 is arranged at the liquid level height position of the upper part of the drum water tank 6. The overflow sewage discharge tank 7 is connected to a filter 15, and the overflow water is filtered by the filter 15 and then recycled, thereby saving the water consumption of the water washing liquid. The bottom of the drum water tank 6 is connected to the filter 15 through a drain pipe 3. The water washing liquid filtered by the filter 15 is sprayed out from the spray pipes 10 through a circulation pump and recycled. A cloth feeding and filament separating roller 8 is arranged at the cloth feeding end of the water washing box, and the fabric 13 is flattened before water washing.

[0016] In operation, the fabric 13 is flattened by the feed roller 8 and then travels sequentially between the lower drum 4, the upper drum 11, and the lower drum 4. Spray pipes 10 on both sides of the upper drum 11 spray washing liquid onto the fabric 13, washing it. The washing liquid flowing down from the fabric 13 collects in the drum water tank 6. Floating debris that detaches after washing floats on the surface and is promptly discharged through the overflow drain 7, ensuring the cleanliness of the washing liquid and improving washing efficiency. Both the washing liquid in the drum water tank 6 and the washing liquid discharged from the overflow drain 7 are filtered by the filter 15 and then sprayed out from the spray pipes 10 by a circulation pump for reuse. When the fabric 13 stretches or shrinks during the immersion washing process, an independent transmission device adjusts the speed ratio between adjacent drums to maintain stable fabric tension and prevent tension imbalance.
