[0025] 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.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a wastewater treatment filtration device, comprising a housing 1, with a turntable 2 rotatably connected to both the front and rear ends of the housing 1, and filter screens 3 installed on both the upper and lower sides of the turntable 2. A rotating shaft 4 is rotatably connected to the center of the turntable 2, and a scraper 5 is fixedly connected to the outside of the rotating shaft 4. The end of the scraper 5 is in close contact with the inner wall of the filter screen 3, and the front and rear sides of the scraper 5 are in close contact with the inner side of the turntable 2. A protective cover 7 is installed on the top of the housing 1, and a drain hopper 8 is installed on the bottom of the housing 1. Support legs 9 for supporting devices are fixedly connected to the lower sides of the left and right ends of the drain hopper 8. A mounting bracket is installed on the front side of the housing 1. Mounting plate 10, with a servo motor 11 mounted on the front center. The drive end of the servo motor 11 is fixedly connected to the front end of the rotating shaft 4. Fixing grooves 12 are provided on the upper sides of both ends of the mounting plate 10. A crank handle 13 is provided inside the fixing groove 12 on the right end of the mounting plate 10, with its end fixedly connected to the front of the turntable 2. A water inlet 23 is provided on the right side of the housing 1, and a discharge outlet 25 is provided on the left side. Baffles 6 are fixedly connected to both the upper and lower sides of the water inlet 23 and the discharge outlet 25 inside the housing 1. A hopper 24 is fixedly connected to the outside of the water inlet 23 on the right side of the housing 1. (Refer to...) Figure 4The upper end of the housing 1 is provided with slots 21 on both the front and rear sides. The slots 21 are equipped with fixing ears 22, and the ends of the fixing ears 22 are fixedly connected to the lower side of the protective cover 7.

[0027] The protective cover 7 can be removed from the top of the housing 1. Using a tool, remove the bolts on the fixing ears 22 to release the protective cover 7 from the top of the housing 1, exposing the internal filter screen 3 for easy disassembly and replacement. To replace the lower filter screen 3, rotate the turntable 2 using the crank handle 13 to swap the positions of the upper and lower filter screens 3, moving the lower filter screen 3 to the upper side for replacement. The upper and lower filter screens 3 have different filter holes, achieving different filtration effects, allowing for selection based on requirements. In wastewater treatment, wastewater is injected into the device from the hopper 24 and outlet 25 on the right side of the casing 1. It is guided by the baffle 6 on the lower side onto the filter screen 3. The liquid passes through the filter screen 3 and is discharged from the drain hopper 8 below. Waste remains on the upper side of the filter screen 3. The scraper 5, which can be rotated by the shaft 4, pushes the waste on the filter screen 3 to the outlet 25 for discharge. This ensures timely treatment of the waste left after filtration, preventing waste from remaining inside the device and affecting filtration efficiency.

[0028] Reference Figure 1 , Figure 5 and Figure 6 Mounting plate 14 is fixedly connected to the front sides of both ends of mounting plate 10. U-shaped plate 15 is fixedly connected to the front side of mounting plate 10 at the opposite end of mounting plate 14. A stop bar 16 is inserted inside the U-shaped plate 15. The end of the stop bar 16 is inserted inside the mounting plate 14. A spring 20 is installed inside the mounting plate 14. A first stop block 17 is fixedly connected to the upper side of the stop bar 16 at the opposite side of U-shaped plate 15. A second stop block 18 is fixedly connected to the front side of the stop bar 16 at the opposite side of U-shaped plate 15. An opening 19 is provided on the front side of mounting plate 14 for cooperating with the second stop block 18.

[0029] The crank handle 13 is moved from the right end of the mounting plate 10 to the left end of the mounting plate 10, causing the turntable 2 to rotate 180 degrees, thus completing the exchange of positions of the filter screens 3 on the upper and lower sides. When the turntable 2 is rotated by the crank handle 13, the stop rod 16 is pushed to one side, and the stop rod 16 is inserted into the mounting plate 14, compressing the internal spring 20 and no longer blocking the crank handle 13. At this time, the crank handle 13 can drive the turntable 2 to rotate. The crank handle 13 moves to the other side of the mounting plate 12 to fix the rotated turntable 2. The servo motor 11 is started, and the servo motor 11 drives the rotating shaft 4 to rotate, thereby causing the rotating shaft 4 to drive the scraper 5 to rotate clockwise to clean the garbage inside the device.

[0030] Working principle: Wastewater is injected into hopper 24 and enters the device through inlet 23. The wastewater is filtered by filter screen 3 on the lower side of the device. The liquid passes through filter screen 3 and is discharged through drain hopper 8, while the waste remains on the upper side of filter screen 3. The servo motor 11 is started to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the scraper 5 to rotate, which moves the remaining waste and discharges it from the discharge port 25 on the left side of the housing 1. The stop lever 16 is moved to the right so that its end no longer blocks the crank handle 13. The crank handle 13 drives the turntable 2 to rotate, thereby changing the position of the filter screens 3 on the upper and lower sides of the turntable 2. Different filter screens 3 achieve different filtration effects. The protective cover 7 is opened to disassemble and replace the filter screen 3 located on the upper side, which is convenient and simple.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
