[0002] In recent years, the textile industry has shown a rapid development trend. At the same time, the discharge of textile wastewater has also continued to rise. This type of wastewater is rich in a large number of pollutants such as organic matter, dyes, grease, and fiber scraps. If it is discharged directly without treatment, it will cause serious harm to the ecological environment and may even destroy the balance of the ecosystem. Therefore, how to efficiently treat and purify textile wastewater has become a key problem that needs to be overcome in the process of promoting the sustainable development of the textile industry.

[0003] Although the new textile wastewater treatment device has achieved certain results in technology research and development, some problems are still exposed in the actual application process. Due to the unscientific and unreasonable structural design of some devices, the wastewater treatment efficiency is difficult to achieve the expected. For example, the fluff generated in the textile production process often floats on the surface of the wastewater and is difficult to settle, resulting in poor treatment effect. Summary of the invention

[0006] Optionally, a sediment conveying motor is fixedly installed at one end of the sediment separation box away from the purified water return pipe, a sediment conveying shaft is installed in the sediment separation box for horizontal rotation, a spiral conveying paddle is spirally provided on the sediment conveying shaft, the bottom of the other end of the sediment separation box is fixedly docked with a sediment collection box vertically downward, the lower end of the sediment collection box is fixedly docked with a sediment discharge pipe, and a filter screen is fixedly installed at the junction of the upper end of the inner cavity of the sediment collection box and the inner cavity of the sediment separation box. A shuttle-shaped purified water slow-flow separation pipe with narrow upper and lower ends and wide in the middle is fixedly installed on the vertical pipe section of the purified water return pipe.

[0007] The textile wastewater treatment device provided by the present invention has the following significant beneficial effects:

[0008] When the device is running, the stirring shaft starts to rotate. With the cooperation of the breaking claws, the flow-pushing paddles and the mixing paddles, the pollutants in the sewage can be quickly and fully mixed with the treatment agents, thereby accelerating the reaction process and significantly improving the efficiency of sewage treatment.

[0009] The breaking claws in the present invention can stir the textile wool floating on the surface of the sewage to form a ball-like structure. This structural change makes it easier for light pollutants that are difficult to settle to settle, effectively solving the problem of unsatisfactory treatment effects caused by the difficulty of light pollutants to settle in traditional treatment methods.

[0010] With the ingenious design of the sediment separation box, combined with the combined action of the sediment conveying motor and the screw conveyor, the device can completely separate the suspended matter and particulate matter in the sewage, thereby improving the purity of the treated water.

[0011] In the present invention, the clean water after sedimentation separation will flow back to the clean water tank through the purified water return pipe. Subsequently, the clean water will be treated twice by the purified water slow flow separation pipe to ensure that the water quality can meet the relevant standards, realize the recycling of purified water, and save water resources to a great extent.

[0012] The device adjusts the water flow rate of the clean water output pipe by controlling the ball valve. This design allows users to flexibly operate according to actual needs. At the same time, users can also adjust the speed of the power motor and the sediment transport motor according to the actual concentration of sewage, so as to better adapt to the treatment needs of sewage of different concentrations, significantly improving the flexibility and adaptability of the treatment process.

[0013] This device adopts a treatment method that combines physics and chemistry. There is no need to use a large amount of chemical agents during the treatment process. This not only reduces the possible pollution to the environment caused by chemical agents, but also realizes the reuse of purified water through an efficient treatment process, reduces the waste of water resources, and fully embodies the concept of environmental protection and energy saving.

[0014] To sum up, the textile wastewater treatment device of the present invention integrates many advantages such as efficient treatment, optimized sedimentation effect, thorough separation, purified water reuse, simple and flexible operation, environmental protection and energy saving, etc., and has important practical significance for improving the wastewater treatment efficiency and water resource utilization rate in the textile industry.

[0030] Example 1: Please refer to Figures 1 to 8 :

[0031] The present invention proposes a textile wastewater treatment device, comprising: a supporting frame 1, a wastewater purification box 2, a driving frame 3, a stirring shaft 4, a sediment separation box 5 and a purified water return pipe 6; the sediment separation box 5 is fixedly installed horizontally on the upper end of the supporting frame 1, the sewage purification box 2 is located above the sediment separation box 5, and the side wall of the sewage purification box 2 is fixedly connected to the supporting frame 1 through a supporting rod; the driving frame 3 is fixedly installed on one end of the top of the sewage purification box 2; the stirring shaft 4 is vertically rotatably provided at the lower end of the driving frame 3, and the end of the sewage purification box 2 away from the driving frame 3 is a clean water tank 203; an inverted L-shaped purified water return pipe 6 is provided between one side of the lower end of the clean water tank 203 and the upper end of the sediment separation box 5; the lower end of the inner cavity of the sewage purification box 2 is communicated with the inner cavity of the sediment separation box 5.

[0032] The sewage purification box 2 is a box structure that is wide at the top and narrow at the bottom. A sewage input pipe 201 is fixedly arranged at the upper middle of the outer end of the sewage purification box 2. The textile sewage is introduced into the sewage purification box 2 through the sewage input pipe 201. Since the sewage purification box 2 adopts a box structure that is wide at the top and narrow at the bottom, the sewage will quickly flow toward the bottom and the partition plate 202 after entering.

[0033] A partition plate 202 is provided between the sewage purification tank 2 and the clean water tank 203. The partition plate 202 is inclined toward the clean water tank 203 along the inner side wall of the sewage purification tank 2. The cavity formed between the lower end of the partition plate 202 and the lower end of the inner cavity of the clean water tank 203 is connected to the inner cavity of the sediment separation tank 5. A clean water output pipe 204 is fixedly installed on the outer side wall of the clean water tank 203 above the purified water reflux pipe 6, and a control ball valve is installed on the clean water output pipe 204.

[0034] The power motor 301 is vertically fixedly installed on the upper end of the driving frame 3, and the lower end of the rotating shaft of the power motor 301 is fixedly connected to the upper end of the stirring shaft 4 through a coupling.

[0035] Among them, a hemispherical breaking claw 401 is fixedly installed on the upper end of the stirring shaft 4, and the uppermost end of the breaking claw 401 extends out of the sewage liquid surface, and a spiral flow-pushing paddle 402 which is wide at the top and narrow at the bottom is fixedly installed on the stirring shaft 4 below the breaking claw 401; a fan-shaped mixing paddle 403 is fixedly installed on the lower end of the stirring shaft 4. After the power motor 301 on the driving frame 3 is started, it drives the stirring shaft 4 to rotate, and the breaking claw 401 on the stirring shaft 4 rotates above the sewage liquid surface, stirring the floating textile wool into a ball-like structure, making it easier to be settled and processed. At the same time, the rotation of the flow-pushing paddle 402 and the mixing paddle 403 enables the sewage to be fully stirred and mixed in the sewage purification tank 2, ensuring that the pollutants in the sewage and the added chemical agents can be evenly contacted and reacted.

[0036] Among them, a sediment conveying motor 501 is fixedly installed at one end of the sediment separation box 5 away from the purified water return pipe 6, a sediment conveying shaft 502 is installed in the sediment separation box 5 for horizontal rotation, and a spiral conveying paddle 505 is spirally provided on the sediment conveying shaft 502. The bottom of the other end of the sediment separation box 5 is fixedly connected to the sediment collection box 503 vertically downward, and the lower end of the sediment collection box 503 is fixedly connected to the sediment discharge pipe 504. A filter screen 506 is fixedly installed at the junction of the upper end of the inner cavity of the sediment collection box 503 and the inner cavity of the sediment separation box 5. The mixed sewage flows into the sediment separation box 5 through the cavity formed between the lower end of the partition plate 202 and the lower end of the inner cavity of the clean water tank 203. In the sediment separation box 5, due to the reduction in flow rate and the action of the agent, the suspended matter and particulate matter in the sewage begin to settle. The sediment conveying motor 501 drives the spiral conveying paddle 505 on the sediment conveying shaft 502 to rotate, pushing the sediment to the sediment collection box 503. After being filtered by the filter screen 506, the sediment is collected in the sediment collection box 503 and finally discharged through the sediment discharge pipe 504.

[0037] Embodiment 2, on the basis of embodiment 1, a shuttle-shaped purified water slow-flow separation tube 601 which is narrow at the upper and lower ends and wide in the middle is fixedly installed on the vertical pipe section of the purified water return pipe 6, and the purified water after sedimentation separation flows back to the clean water tank 203 through the purified water return pipe 6. The purified water slow-flow separation tube 601 on the purified water return pipe 6 can reduce the speed of purified water return and further separate the tiny suspended matter that may remain. After accumulating to a certain amount in the clean water tank 203, the purified water can be discharged through the purified water output pipe 204 for reuse or further treatment.

[0038] A method for treating textile wastewater:

[0039] First, textile wastewater is introduced into the wastewater purification box 2 through the wastewater inlet pipe 201. Since the wastewater purification box 2 adopts a box structure that is wide at the top and narrow at the bottom, the wastewater will quickly flow toward the bottom and the partition plate 202 after entering;

[0040] After the power motor 301 on the driving frame 3 is started, it drives the stirring shaft 4 to rotate, and the breaking claws 401 on the stirring shaft 4 rotate above the sewage surface, stirring the floating textile wool into a ball-like structure, making it easier to be settled and processed. At the same time, the rotation of the push flow paddle 402 and the mixing paddle 403 makes the sewage fully stirred and mixed in the sewage purification tank 2, ensuring that the pollutants in the sewage and the added chemical agents can evenly contact and react;

[0041] The stirred and mixed sewage flows into the sediment separation box 5 through the cavity formed between the lower end of the partition plate 202 and the lower end of the inner cavity of the clean water tank 203. In the sediment separation box 5, due to the reduced flow rate and the action of the agent, the suspended matter and particulate matter in the sewage begin to settle. The sediment conveying motor 501 drives the spiral conveying paddle 505 on the sediment conveying shaft 502 to rotate, pushing the sediment to the sediment collection box 503. After being filtered by the filter screen 506, the sediment is collected in the sediment collection box 503 and finally discharged through the sediment discharge pipe 504.

[0042] The purified water after sedimentation separation flows back to the purified water tank 203 through the purified water return pipe 6. The purified water slow-flow separation pipe 601 on the purified water return pipe 6 can reduce the speed of purified water return and further separate the possible residual micro suspended matter. After a certain amount of purified water accumulates in the purified water tank 203, the purified water can be discharged through the purified water output pipe 204 for reuse or further treatment.

[0043] During the entire treatment process, the flow rate of the clean water output pipe 204 can be adjusted by controlling the ball valve to meet different usage requirements. At the same time, the speed of the power motor 301 and the sediment transport motor 501 can be adjusted according to actual conditions to optimize the treatment effect and efficiency.
