Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, specifically a wastewater filtration device with a self-cleaning function. Background Technology

[0002] The wastewater filtration device with self-cleaning function combines physical filtration with automatic cleaning to achieve integrated wastewater purification and filter element maintenance. The core principle is to use multiple layers of filter media (such as filter screens, activated carbon, ceramic filter elements, etc.) to trap suspended solids, colloids, organic matter and heavy metals in the wastewater. The automatic cleaning module (such as backwashing, ultrasonic vibration, mechanical scraping, etc.) regularly removes pollutants from the surface and inside of the filter element to prevent clogging, maintain filtration efficiency and reduce manual maintenance costs.

[0003] Existing wastewater filtration devices with self-cleaning functions rely heavily on electric power. Power outages or control system failures can cause the device to shut down completely. The lack of a backup manual cleaning mechanism may lead to the interruption of the entire wastewater treatment process. Furthermore, replacing the cleaning components is cumbersome, requiring the disassembly of multiple fasteners. Therefore, a wastewater filtration device with self-cleaning function is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater filtration device with a self-cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wastewater filtration device with a self-cleaning function includes a housing. Symmetrically arranged limiting strips are fixedly connected to the inner side of the housing. A filter layer located inside the housing is slidably connected to the outer side of the limiting strips. A connecting groove is formed on the front side of the housing, and a sealing ring is provided inside the connecting groove. A connecting ring is fixedly connected to the front side of the sealing ring, and a sealing cap is fixedly connected to the front side of the connecting ring. A bolt passing through the sealing ring, connecting ring, and sealing cap is threaded inside the housing. A bearing is rotatably connected inside the filter layer, and a retaining ring located inside the filter layer is fixedly connected to the inner side of the bearing. A motor is fixedly connected to the bottom end of the housing. The output end of the machine is fixedly connected to a rotating shaft that passes through the bottom of the outer casing. A connecting rod is threaded to the inner side of the rotating shaft. A stirring shaft that passes through the top of the outer casing is fixedly connected to the top of the connecting rod, and the stirring shaft is located inside the fixing ring. An operating wheel is fixedly connected to the top of the stirring shaft. Limiting plates located inside the fixing ring are fixedly connected to both sides of the stirring shaft. A limiting groove is opened on one side of the stirring shaft. A spring located inside the limiting groove is fixedly connected inside the stirring shaft. A fixing block is fixedly connected to the bottom of the spring. A support plate located inside the limiting groove is provided at the bottom of the fixing block. Cleaning strips located on both sides of the stirring shaft are fixedly connected to the bottom of the support plate.

[0007] Preferably, there are several cleaning strips, and the bottom end of the cleaning strip is attached to the top end of the filter layer.

[0008] Preferably, the outer shape of the retaining ring matches the inner shape of the bearing, and the height of the retaining ring matches the height of the filter layer.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A wastewater filtration device with a self-cleaning function includes a housing 1. A symmetrically arranged limiting strip 2 is fixedly connected to the inner side of the housing 1. A filter layer 3 located inside the housing 1 is slidably connected to the outer side of the limiting strip 2. A connecting groove 4 is provided on the front side of the housing 1. A sealing ring 5 is provided inside the connecting groove 4. A connecting ring 6 is fixedly connected to the front side of the sealing ring 5. A sealing cover 7 is fixedly connected to the front side of the connecting ring 6. A bolt 8, threaded through the sealing ring 5, connecting ring 6, and sealing cover 7, is threaded inside the housing 1. A bearing 9 is rotatably connected inside the filter layer 3. A retaining ring 10 located inside the filter layer 3 is fixedly connected to the inner side of the bearing 9. A motor 11 is fixedly connected to the bottom end of the housing 1. The output end of the motor 11 is fixedly connected to a device penetrating the housing. A rotating shaft 12 is located at the bottom of the housing 1. A connecting rod 13 is threadedly connected to the inner side of the rotating shaft 12. A stirring shaft 14, which passes through the top of the housing 1, is fixedly connected to the top of the connecting rod 13. The stirring shaft 14 is located inside the fixing ring 10. An operating wheel 15 is fixedly connected to the top of the stirring shaft 14. Limiting plates 16, located inside the fixing ring 10, are fixedly connected to both sides of the stirring shaft 14. A limiting groove 17 is opened on one side of the stirring shaft 14. A spring 18, located inside the limiting groove 17, is fixedly connected to the inside of the stirring shaft 14. A fixing block 19 is fixedly connected to the bottom of the spring 18. A support plate 20, located inside the limiting groove 17, is provided at the bottom of the fixing block 19. Cleaning strips 21, located on both sides of the stirring shaft 14, are fixedly connected to the bottom of the support plate 20.

[0024] There are several cleaning strips 21, and the bottom end of the cleaning strip 21 fits into the top end of the filter layer 3, which can significantly improve the cleaning effect on the surface of the filter layer 3. The outer shape of the fixing ring 10 matches the inner shape of the bearing 9, and the height of the fixing ring 10 matches the height of the filter layer 3, which can effectively wrap the stirring shaft 14, prevent the stirring shaft 14 from directly contacting the filter layer 3, and reduce friction. The width of the fixing block 19 matches the width of the limiting groove 17, and a spring 18 is fixedly connected to the top of the fixing block 19 relative to the center position, which can improve the stability of the fixing block 19 and prevent the fixing block 19 from wobbling left and right. The diameter of the stirring shaft 14 matches the diameter of the rotating shaft 12, and the shape of the stirring shaft 14 matches the shape of the rotating shaft 12, both of which are cylindrical.

[0025] Workflow: When a wastewater filtration device with a built-in cleaning function is required, the entire system is powered externally. Wastewater is first injected through a pipe on the outer casing 1. The wastewater undergoes multi-stage filtration through the existing filter layer 3. The filtered wastewater is discharged through a pipe at the bottom of the outer casing 1. The output of the motor 11 drives the rotating shaft 12, connecting rod 13, and stirring shaft 14 to rotate. The connecting rod 13 is connected to the rotating shaft 12 in the opposite direction, so the rotating shaft 12 driving the connecting rod 13 to rotate in the forward direction will not cause any loosening. The stirring shaft 14 drives the support plate 20 and cleaning strip 21 to rotate under the guidance of the bearing 9 and the fixing ring 10. The cleaning strip 21 cleans the surface of the filter layer 3. The spring 18 and fixing block 19 can compress the support plate 20 and cleaning strip 21 to fix them in place. When there is no power, the operating wheel 15 can directly drive the stirring shaft 14 and cleaning strip 21 to rotate, achieving the same cleaning effect. The bearing 9 and fixing ring 10 effectively reduce the friction between the stirring shaft 14 and the filter layer 3 when the stirring shaft 14 rotates, reducing wear and power consumption. At the same time, they reduce gaps and improve rotational stability. The bearing 9 and fixing ring 10 are driven by the limiting plates 16 on both sides of the stirring shaft 14. When the cleaning strip 21 needs to be replaced, the support plate 20 is lifted upwards, and the support plate 20 presses the fixing block 19 upwards. At this time, the fixing block 19 will compress the spring 18. When the cleaning strip 21 is fully inserted into the limiting groove 17, the support plate 20 and the cleaning strip 21 can be pulled out directly to complete the replacement. When the filter layer 3 needs to be replaced, the bolt 8 is removed, and the sealing cover 7 is separated from the outer shell 1. The sealing cover 7 drives the connecting ring 6 and the sealing ring 5 to be taken out from the connecting groove 4. Then, the stirring shaft 14 is rotated in the opposite direction to separate the connecting rod 13 from the rotating shaft 12. Then, the stirring shaft 14 can be pulled out upwards. After removing the stirring shaft 14, the filter layer 3 can be pulled out directly for replacement.
