Description

Technical Field

[0001] This utility model relates to the technical field of polyester fabric dyeing equipment, and more specifically, to a water-saving device for polyester fabric dyeing. Background Technology

[0002] Polyester fabric, also known as polyester fiber, is a synthetic fiber obtained by spinning polyester, which is formed by the condensation polymerization of organic dicarboxylic acid and diol. It is also called PET fiber. It belongs to high molecular compounds. The biggest advantage of polyester fiber is its excellent wrinkle resistance and shape retention. It has high strength and elastic recovery ability. It is durable, wrinkle-resistant and does not stick to lint. It is usually dyed by immersing it in a dyeing bath.

[0003] Currently, when dyeing polyester fabric, the dyeing solution is usually discharged directly without recycling treatment. This not only leads to the waste of dyes, auxiliaries and water resources, but also increases the wastewater treatment load and the risk of environmental pollution. At the same time, since the dyeing solution cannot be recycled, companies need to continuously replenish fresh dyeing solution, which increases production costs. From the perspectives of both resource efficiency and economic benefits, the unsustainability of the existing process is highlighted. Utility Model Content

The outer surface of the filter box 11... A gear ring 5 is fixedly installed, and a gear 4 meshes with the gear ring 5. Polyester fabric is immersed in the dyeing solution in the dyeing tank 1 to dye the fabric. After dyeing, the valve on the drain pipe 10 is opened to discharge the used dyeing solution into the filter tank 11. The used dyeing solution is filtered through the primary filter 17, secondary filter 18, and tertiary filter 19 in the filter tank 11, separating impurities from the dyeing solution and facilitating its recycling. The motor 9 on the bottom surface of the dyeing tank 1 is activated, driving the gear 4 to rotate. Simultaneously, the gear 4 rotates the gear ring 5 on the outer surface of the filter tank 11, causing the filter tank 11 to rotate. This centrifugal filtration of the dyeing solution improves the filtration efficiency.

[0029] Please see Figure 1 and Figure 2 Rotating rods 15 are installed on both sides of the bottom surface of the dyeing box 1 away from the motor 9. One end of the rotating rod 15 passes through the primary filter 17, the secondary filter 18, and the tertiary filter 19. A cleaning brush 16 is fixedly connected to the rotating rod 15 above the primary filter 17, the secondary filter 18, and the tertiary filter 19. When the filter box 11 rotates, the cleaning brush 16 on the rotating rod 15 can clean the impurities on the primary filter 17, the secondary filter 18, and the tertiary filter 19, preventing impurities from accumulating on the primary filter 17, the secondary filter 18, and the tertiary filter 19 and causing blockage, thus maintaining their normal use.

[0030] Please see Figure 1 and Figure 2 The primary filter 17, secondary filter 18, tertiary filter 19, and filter box 11 are circular structures. The cleaning brush 16 is matched with the primary filter 17, secondary filter 18, and tertiary filter 19. The cleaning brush 16 can clean the impurities on the primary filter 17, secondary filter 18, and tertiary filter 19 to prevent impurities from accumulating on the filter screens and causing blockage, thereby ensuring their normal subsequent use.

[0031] Please see Figure 1 and Figure 3 A mounting plate 7 is fixedly connected to one side surface of the support plate 3, and a circulation pump 6 is fixedly installed on the top surface of the mounting plate 7.

[0036] Working principle: The polyester fabric is immersed in the dyeing solution in the dyeing tank 1 to dye it. After dyeing, the valve on the drain pipe 10 is opened to discharge the used dyeing solution into the filter tank 11. The used dyeing solution is filtered through the primary filter 17, secondary filter 18, and tertiary filter 19 in the filter tank 11, separating impurities from the dyeing solution for easy recycling. The motor 9 on the bottom surface of the dyeing tank 1 is activated, driving the gear 4 to rotate. The rotation of the gear 4 simultaneously drives the filter tank... The toothed ring 5 on the outer surface of filter box 11 rotates, causing filter box 11 to rotate, which can centrifuge and filter the dyeing solution. This improves the filtration effect of the dyeing solution, facilitates its recycling, and reduces production costs. While the filter box 11 is rotating, the cleaning brush 16 on the rotating rod 15 can clean the impurities on the primary filter screen 17, secondary filter screen 18, and tertiary filter screen 19, preventing impurities from accumulating on the primary filter screen 17, secondary filter screen 18, and tertiary filter screen 19 and causing blockage. This ensures normal operation and continuous filtration of the dyeing solution.
