Description

Technical Field

[0001] This utility model relates to the field of cleaning, specifically a non-reduction cleaning device based on a one-bath dyeing process. Background Technology

[0002] One-bath dyeing typically refers to a method where dyeing and subsequent treatments are completed in the same bath, with the entire dyeing process taking place within the same dye bath. This process is mainly used for dyeing blended fabrics, where each selected dye is used to dye the fabric in the same bath, but frequent rinsing with clean water is necessary.

[0003] In existing technologies, during the cleaning process, the cleaning efficiency is too slow due to the low water temperature and the long waiting time for the water source to heat up. Furthermore, the presence of internal silk fibers affects the cleaning quality when the wastewater is discharged. Therefore, a non-reduction cleaning device based on a one-bath dyeing process is proposed to address the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1-4 As shown, a non-reduction cleaning device based on a one-bath dyeing process includes a dyeing tank 1; a support plate 2 is set on one edge of the top of the dyeing tank 1, and a circulating water pump 3 is installed on the surface of the support plate 2. The water pump 3's pumping end is connected to a barrel pipe 5 through a multi-segment pipe 4. A cavity is opened in the inner wall of the barrel pipe 5 and a spiral coil 6 is installed inside. One end of the spiral coil 6 is connected to the multi-segment pipe 4 and the other end is connected to one side of the bottom of the dyeing tank 1; the water pump 3's delivery end is connected to one side of the top of the dyeing tank 1 through an L-pipe 7; a filter box 8 is set on one side of the cavity of the barrel pipe 5, and the spiral coil 6 is connected to the filter box 8 through a spiral connection. A square frame 9 is slidably connected inside the filter box 8, and a filter screen 10 is installed inside the square frame 9; one end of the barrel pipe 5 is connected to the surface of the dyeing tank 1 and the other end is connected to an inlet pipe 11. A shut-off valve 12 is set on the surface of both the L-pipe 7 and the multi-segment pipe 4.

[0022] During operation, the circulating water pump 3 starts and draws high-temperature wastewater from the dyeing tank 1, which is then transported to the spiral coil 6 through the multi-section pipe 4. At the same time, clean water enters the annular clean water flow channel in the cavity of the barrel pipe 5 from the inlet pipe 11. The waste heat of the wastewater is conducted to the clean water preheating through the pipe wall of the spiral coil 6. After preheating, the clean water is reinjected into the dyeing tank 1 through the L pipe 7. The filter screen 10 in the filter box 8 intercepts fibrous impurities in the wastewater. The shut-off valve 12 controls the opening and closing of the pipeline. The waste heat recovery of the spiral coil 6 and the impurity interception of the filter screen 10 work together to solve the problems of low washing water temperature and water pollution, and improve the washing efficiency.

[0023] Furthermore, a guide rail groove is provided on the inner wall of the filter box 8 to slide with the square frame 9, and a handle is provided on the outer wall of the square frame 9 and the handle extends to the outside of the filter box 8.

[0024] During operation, the guide rail groove on the inner wall of the filter box 8 slides in conjunction with the square frame 9, and the handle is exposed on the surface of the filter box 8. The filter screen 10 can be replaced or cleaned by pulling out the square frame 9. The guide rail groove restricts the frame from shifting.

[0025] Furthermore, the spiral coil 6 is evenly distributed in the cavity of the barrel tube 5 in a multi-layer spiral structure, and an annular clean water flow channel is formed between its tube wall and the inner wall of the barrel tube 5.

[0026] During operation, the multi-layer spiral structure of the spiral coil 6 is evenly distributed in the cavity of the barrel tube 5. Its tube wall and the inner wall of the barrel tube 5 form an annular flow channel. When the clean water flows along the annular flow channel, it exchanges heat with the high-temperature wastewater in the spiral coil 6 in a countercurrent flow.

[0027] Furthermore, the gate valve 12 is a manual butterfly valve, with its valve plate rotation axis perpendicular to the pipeline centerline, and a sealing rubber ring is provided on the edge of the valve plate;

[0028] When in operation, the valve plate of the manual butterfly valve rotates around the vertical axis. When closed, the sealing rubber ring presses against the inner wall of the pipe to block the water flow. When opened, the valve plate is parallel to the pipe to reduce flow resistance.

[0029] Furthermore, a flange connector is provided at the inlet end of the water inlet pipe 11, the inner diameter of which is consistent with the inner diameter of the through end of the barrel pipe 5 and the axis coincides with it.

[0030] During operation, the inlet flange connector of the water inlet pipe 11 is coaxially connected to the through end of the barrel pipe 5. After the flange bolts are fixed, the water flows smoothly into the barrel pipe 5 along the axis, avoiding turbulent energy loss.

[0031] Furthermore, the filter screen 10 is a stainless steel woven mesh, and its mesh size decreases sequentially from the water inlet side to the water outlet side to form a gradient filtration structure.

[0032] During operation, the larger mesh on the inlet side of filter 10 intercepts coarse fibers, while the smaller mesh on the outlet side filters out fine impurities. The stainless steel material is corrosion-resistant and can be repeatedly washed and reused.

[0033] Working principle: The circulating water pump 3 draws high-temperature wastewater from the dyeing tank 1 and enters the spiral coil 6 through the multi-section pipe 4. The purified water flows into the annular purified water channel of the tank pipe 5 through the inlet pipe 11 and exchanges heat with the wastewater in the spiral coil 6 in a countercurrent flow to raise its temperature. The preheated purified water is reinjected into the dyeing tank 1 through the L pipe 7 for cleaning. At the same time, the wastewater carries impurities into the filter box 8. The gradient filter screen 10 intercepts the silk floss particles step by step. The square frame 9 can be pulled out and the filter screen can be replaced through the guide rail groove. The shut-off valve 12 controls the pipeline opening and closing. The flange connection ensures that the water flow is stable in the axial direction, realizing the synergistic effect of waste heat recovery, impurity filtration and cleaning water temperature increase.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
