[0002] Wastewater can be defined as liquid or water carrying waste that is discharged from residential, government, commercial, or industrial areas and mixed with groundwater, surface water, snow, etc. There are many categories of wastewater, and correspondingly, many technologies and processes exist to reduce its environmental impact.

[0003] However, existing wastewater treatment purification tanks do not have easily replaceable filters. Replacing the filters in existing purification tanks is often time-consuming and laborious, reducing replacement efficiency and making them inconvenient to use. Furthermore, existing purification tanks often lack the function of mixing wastewater and chemicals, resulting in insufficient mixing of wastewater and chemicals and reducing the wastewater treatment effect. Therefore, there is an urgent need for a wastewater treatment purification tank to solve the above problems. Utility Model Content

[0022] 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 protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides an embodiment of a wastewater treatment purification tank, comprising a support 1, a stirring structure 2, a connecting pipe 3, a filtration structure 4, and an outlet pipe 5. The stirring structure 2 includes a stirring bucket 21, the stirring bucket 21 is fixedly connected to the inner wall of the top of the support 1, the stirring bucket 21 is rotatably connected to a stirring rod 25, and the bottom of the stirring bucket 21 is fixedly connected to the connecting pipe 3. The filtration structure 4 includes a filter bucket 41, the bottom of the connecting pipe 3 is fixedly connected to the filter bucket 41, the filter bucket 41 is slidably connected to two fixing frames 42, the fixing frames 42 are snapped with filter plates 46, the front side of the fixing frames 42 is fixedly connected to a baffle 44, the left and right ends of the baffle 44 are threadedly connected to two threaded rods 48, the left and right ends of the filter bucket 41 are rotatably connected to limiting plates 410, and the bottom of the filter bucket 41 is fixedly connected to the outlet pipe 5.

[0024] Furthermore, the top of the mixing tank 21 is fixedly connected to the water inlet pipe 22 and the chemical dosing pipe 23, and the top of the mixing tank 21 is fixedly connected to the motor 24. The drive shaft of the motor 24 is fixedly connected to the stirring rod 25. When the motor 24 is turned on, it drives the stirring rod 25 to stir the sewage and the chemical. The stirring rod 25 can stir the sewage and the chemical, so that the sewage and the chemical can be mixed more evenly, thereby improving the sewage treatment efficiency.

[0025] Furthermore, both the connecting pipe 3 and the outlet pipe 5 are equipped with solenoid valves. Opening the solenoid valve on the connecting pipe 3 allows the mixed wastewater to be transported into the filter bucket 41, while opening the solenoid valve on the outlet pipe 5 allows the filtered wastewater to be discharged.

[0026] Furthermore, the top of the fixed frame 42 is provided with a slot 43, which is engaged with the outer frame of the filter plate 46. The filter plate 46 filters the sewage. The filter plate 46 consists of a PP cotton layer filter screen and an activated carbon layer filter screen. The PP cotton layer can filter large particulate impurities, and the activated carbon layer can eliminate odors.

[0027] Furthermore, a handle 45 is fixedly connected to the front side of the baffle 44. The surface of the handle 45 is provided with an anti-slip coating. Pulling the handle 45 causes the fixed frame 42 to move forward, and the fixed frame 42 can be pulled out.

[0028] Furthermore, a hand-tightening handle 47 is fixedly connected to the front side of the threaded rod 48. The surface of the hand-tightening handle 47 is provided with uneven patterns. Rotating the hand-tightening handle 47 causes the threaded rod 48 to move forward, so that the threaded rod 48 is no longer fixed to the position of the baffle 44.

[0029] Furthermore, the limiting plate 410 is rotatably connected to the fixing bolt 49, which is fixedly connected to the filter barrel 41. The top of the limiting plate 410 is fixedly connected to the lever 411. By moving the lever 411, the limiting plate 410 is rotated, so that the limiting plate 410 no longer fixes the position of the filter plate 46, and the filter plate 46 can be replaced or cleaned.

[0030] Working principle:

[0031] During operation, wastewater is fed into the mixing tank 21 through the inlet pipe 22, and flocculants and other chemicals are fed into the mixing tank 21 through the dosing pipe 23. The motor 24 is turned on, causing it to drive the stirring rod 25 to mix the wastewater and chemicals. The stirring structure 2 ensures a more uniform mixture, improving wastewater treatment efficiency. After mixing, the solenoid valve on the connecting pipe 3 is opened, allowing the mixed wastewater to be transported to the filter tank 41. The wastewater is then filtered through the filter plate 46, which consists of a PP cotton layer filter and an activated carbon layer filter. The PP cotton layer filters out large particles, while the activated carbon layer filters out smaller particles. The filter plate 46 can eliminate odors. When it is necessary to replace the filter plate 46, turn the hand-tightening handle 47 to move the threaded rod 48 forward, so that the threaded rod 48 is no longer fixing the position of the baffle 44. Pull the handle 45 to move the fixing frame 42 forward, so that the fixing frame 42 can be pulled out. Move the lever 411 to rotate the limiting plate 410, so that the limiting plate 410 is no longer fixing the position of the filter plate 46. Then the filter plate 46 can be replaced or cleaned. The filter structure 4 can filter sewage, filter large particles of impurities and eliminate odors. It is easy to install and disassemble, improves replacement efficiency and is easy to use.
