[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A wastewater filtration device for water treatment, comprising:

[0024] The chamber 1 has an exhaust and pressure relief structure 3 located at the rear center of its upper surface, a wastewater filtration structure 4 located at the center of its interior, and a wastewater collection structure 5 located at the lower center of one side of the chamber 1. An inlet solenoid valve is located at the center of the upper surface of the chamber 1, and a drain solenoid valve is located at the center of the lower surface of the chamber 1. A control panel 2 is located at the lower center of the front surface of the chamber 1. When wastewater filtration is required, the inlet solenoid valve is opened, allowing wastewater to enter the chamber 1 from the top. After a period of operation, sediment and impurities will accumulate at the bottom of the chamber 1. Opening the drain solenoid valve removes these sediments, keeping the interior of the device clean and preventing any impact on treatment efficiency or blockage. The control panel 2 allows for setting the opening and closing times of the inlet solenoid valve, drain solenoid valve, self-priming pump 502, and drain solenoid valve 503, as well as the speed of the servo motor 404. These settings can be flexibly adjusted according to actual wastewater treatment needs and water quality to achieve the best wastewater filtration effect.

[0025] The wastewater filtration structure 4 includes two servo motors 404, which are respectively located on both sides of the center of the front face of the housing 1. The output ends of the two servo motors 404 pass through the front face of the housing 1 and extend into the interior of the housing 1, and each end is fixedly connected to a stirring rod 405. Inside the housing 1, there are lifting boxes 401 located near the upper and lower center. Sliding frames 402 are slidably connected inside each lifting box 401, and filter screens 403 are located at the center of each sliding frame 402. When wastewater enters the housing 1 through the inlet solenoid valve, it passes through the upper... The filter screen 403 inside the sliding frame 402 performs preliminary filtration and particulate interception. By starting two servo motors 404, the stirring rod 405 is driven to rotate. The rotation of the stirring rod 405 can make the wastewater in the tank 1 form a vortex or circulation, breaking up any dead zones in the wastewater flow and allowing the wastewater to contact the filter components more evenly. After the water flow is made uniform by stirring, impurities and particulate matter in the wastewater will be intercepted by the filter screen 403 at the bottom during the flow. As time goes by and the water continues to flow, impurities accumulate on the filter screen 403.

[0026] The exhaust pressure relief structure 3 includes an exhaust frame 301, which is located at the rear center of the upper end face of the housing 1. Exhaust ports 302 are located at the center of both side walls of the exhaust frame 301, and air inlets 303 are located at the center of the lower end face of both exhaust frames 301. A telescopic rod 304 is located at the lower center of the interior of the exhaust frame 301. Sliding plates 305 are located at the center of both the upper and lower end faces of the telescopic rod 304. A compression spring 306 is fitted onto the outer wall of the telescopic rod 304. Under normal conditions, the exhaust pressure relief structure 3 mainly functions to balance pressure and discharge gas. The function of the body is as follows: During the operation of the device, the internal pressure of the box 1 changes due to the entry of wastewater, etc. The gas inside the box 1 enters the exhaust frame 301 through the air inlet 303. When the pressure inside the box 1 is too high, the compression spring 306 is compressed, and the telescopic rod 304 drives the sliding plate 305 to move. The gas is discharged from the box 1 through the exhaust ports 302 on both sides to maintain the internal pressure balance. When the pressure returns to normal, the compression spring 306 returns to its original state, and the sliding plate 305 returns to its initial position to prevent the pressure inside the box 1 from being too high.

[0027] The wastewater collection structure 5 includes a wastewater tank 501, which is located at the lower center of one side of the tank body 1. A self-priming pump 502 is located at the upper center of one inner wall of the wastewater tank 501. The output end of the self-priming pump 502 passes through the inner wall of the wastewater tank 501 and the side wall of the tank body 1 to the interior of the tank body 1. A drain solenoid valve 503 is located at the lower center of one side wall of the wastewater tank 501. A door is rotatably connected to the center of the upper end face of the wastewater tank 501. As the wastewater in the tank body 1 is treated, the self-priming pump 502 of the wastewater tank 501 is started, drawing the wastewater that has undergone preliminary sedimentation and filtration into the wastewater tank 501 for storage. When the wastewater in the wastewater tank 501 reaches a certain level or meets the usage requirements, if it is necessary to discharge the wastewater, the drain solenoid valve 503 is opened to discharge the wastewater.

[0028] The working principle of this utility model is as follows:

[0029] When the device starts working, the inlet solenoid valve is opened, and the wastewater to be treated flows into the tank 1. It undergoes preliminary filtration and particulate interception through the filter screen 403 inside the upper sliding frame 402. Simultaneously, two servo motors 404 are activated, driving the stirring rod 405 to rotate within the tank 1. The stirring action creates a good circulation or vortex in the wastewater, breaking up any stratification or localized stagnation within the wastewater. This results in a more even distribution of impurities and pollutants, allowing the wastewater to contact the filter components more fully and evenly, improving the filtration effect and preventing localized accumulation of impurities that would accelerate clogging of the filter screen 403. Other parts cannot fully perform their filtration function. This can be effectively improved by stirring. As the water flow becomes uniform through stirring, various impurities, large suspended particles, and solid debris in the wastewater encounter the filter screen 403 at the bottom during the continuous water flow. They are intercepted in the mesh of the filter screen 403 and cannot continue to move with the water flow. In this process, such as mud, paper scraps, and plastic fragments, they are separated out, achieving a preliminary physical filtration function. Under normal operating conditions, as wastewater continuously enters the tank 1, and there may be some chemical reactions or gases carried in the raw water, the pressure inside the tank 1 will change to a certain extent.

[0030] When the pressure inside the tank 1 is too high, the compression spring 306 is compressed, and the telescopic rod 304 drives the sliding plate 305 to move. The gas is discharged from the tank 1 through the exhaust ports 302 on both sides, maintaining the internal pressure balance. When the pressure returns to normal, the compression spring 306 returns to its original state, and the sliding plate 305 returns to its initial position to prevent the pressure inside the tank 1 from being too high. As the wastewater in the tank 1 is continuously treated, the self-priming pump 502 in the wastewater tank 501 is turned on. The self-priming pump 502 draws the pre-filtered wastewater in the tank 1 into the wastewater tank 501 through the output end for storage. The wastewater tank 501 can play a role in temporary storage and buffering, accommodating wastewater after a certain degree of treatment to meet different subsequent use needs or discharge conditions. When the wastewater stored in the wastewater tank 501 reaches a certain amount, meeting the discharge conditions or the needs of production and treatment processes, the drain solenoid valve 503 is opened, and the wastewater is discharged from the wastewater tank 501, which can be guided to the next treatment process or discharged to a designated location.

[0031] In addition, after the device has been running for a long time, a lot of sediment, impurities and other solid substances will accumulate at the bottom of the tank 1 and on the filter components. If these sediments are not discharged in time, they will occupy the space of the tank 1, affect the wastewater treatment volume, breed bacteria and microorganisms, and cause secondary pollution to the water quality. At the same time, long-term accumulation may also damage the device components. At this time, opening the drain solenoid valve will discharge these sediments from the device, keep the inside of the device clean, and ensure the treatment effect and normal operation of the device.

[0032] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
