Description

Technical Field

[0001] The utility model relates to the technical field of grid sewage treatment, in particular to an assembled sewage treatment grid. Background Technique

[0002] An assembled sewage treatment grid is a device used for sewage treatment, usually used to remove solid particles in sewage. It consists of multiple components and can be assembled and installed as needed. This kind of grid is usually used in sewage treatment plants, sewage treatment in industrial production processes, and other applications that require the removal of solid waste.

[0003] After retrieval, a sewage treatment filter grid with the publication number CN220939322U, which relates to the technical field of sewage treatment, includes a frame. A plurality of grid mesh sheets are arranged inside the frame, and the plurality of grid mesh sheets are connected to the frame through a connecting mechanism. Cleaning mechanisms are arranged on both sides of the frame. The plurality of grid mesh sheets can be detachably arranged in the frame separately. Compared with the traditional integral grid, this setting can replace only the grid mesh sheets in a certain area when damage occurs in that area, thereby reducing the maintenance cost, and can also reduce the volume during transportation, facilitating transportation. During assembly, the grid mesh sheets are spliced together, the corresponding threaded sleeves are inserted into the corresponding connection holes, and then the screws are tightened to fix the grid mesh sheets.

[0004] Based on the above patent, by starting the motor to drive the ball screw to rotate, the ball screw drives the screw sleeve to slide along the inner wall of the first fixed column, and the screw sleeve drives the scraper to move synchronously. During the movement of the scraper, the debris on the grid mesh sheets is scraped off, realizing the regular cleaning of the grid mesh sheets, avoiding the blockage of the grid mesh sheets, reducing the manual labor intensity. The plurality of grid mesh sheets can be detachably arranged in the frame separately. Compared with the traditional integral grid, this setting can replace only the grid mesh sheets in a certain area when damage occurs in that area, thereby reducing the maintenance cost, and can also reduce the volume during transportation, facilitating transportation. During assembly, the grid mesh sheets are spliced together, the corresponding threaded sleeves are inserted into the corresponding connection holes, and then the screws are tightened to fix the grid mesh sheets. However, during the use of this patent, the scraping effect of the scraper on the grid is not good, affecting the cleaning effect of the grid plate. If the cleaning is not timely or thorough, dirt will accumulate on the grid plate, resulting in reduced efficiency and increased maintenance and operation costs. Content of the Utility Model

The waterproof motor 6 can be used in water and has a waterproof effect. The top of the filter screen 5 is in close contact with the outer wall of the cleaning wheel 13.

[0027] Specifically:

[0028] Referring to Figure 2 , Figure 3 and Figure 4 , a one-way screw rod 11 is fixedly connected to the driving end of the waterproof motor 6. A transfer block 12 is threadedly connected to the outer wall of the one-way screw rod 11. The left end outer wall of the transfer block 12 is rotatably connected to a cleaning wheel 13. A transmission gear 14 is fixedly connected to the left end of the cleaning wheel 13. A toothed groove plate 15 is meshed and connected to the outer wall of the transmission gear 14. When the waterproof motor 6 is started, the waterproof motor 6 drives the one-way screw rod 11 to drive the transfer block 12 to rotate, so that the cleaning wheel 13 connected to the transfer block 12 moves. And the transmission gear 14 at one end of the cleaning wheel 13 rotates along the toothed groove plate 15, so that the cleaning wheel 13 cleans the filter screen 5 when rotating, thereby improving the cleaning effect on the filter screen 5. And the improvement of the cleaning effect can effectively remove solid particles on the filter screen 5. The front end of the one-way screw rod 11 is rotatably connected to the front end of the inner wall of the second chute plate 3. The outer wall of the transfer block 12 is slidably connected to the inner wall of the second chute plate 3. The bottom end of the toothed groove plate 15 is fixedly connected to the left side of the top of the connecting frame 1, reducing the load on downstream treatment equipment, thereby improving the efficiency of the entire sewage treatment system, reducing the frequency and cost of maintenance and cleaning. And by driving the adjusting bolt 8 to rotate through the hexagonal groove 9, reducing the load on downstream treatment equipment, thereby improving the efficiency of the entire sewage treatment system, reducing the frequency and cost of maintenance and cleaning.

[0031] Working principle: The filter screen 5 at the grid frame 4 can filter impurities in the sewage. The waterproof motor 6 can be used in water and has a waterproof effect. When the waterproof motor 6 is started, the waterproof motor 6 drives the one-way screw rod 11 to drive the adapter block 12 to rotate, and the cleaning wheel 13 connected to the adapter block 12 moves. The transmission gear 14 at the cleaning wheel 13 rotates along the tooth groove plate 15, and the cleaning wheel 13 cleans the filter screen 5 when rotating, thereby improving the cleaning effect on the filter screen 5. The improvement of the cleaning effect can effectively remove solid particles on the filter screen 5. By rotating the adjusting bolt 8 through the hexagonal groove 9, the adapter ring 10 drives the first connecting plate 16 to make the support plate 17 contract inward, reducing the fixing effect of the support plate 17 on the grid frame 4, so that the grid frame 4 can fall off. By rotating the adjusting bolt 8 in the reverse direction, the support plates 17 connected to the first connecting plates 16 fix the grid frame 4 on the second connecting plates 18, and the grid frame 4 is installed. Regularly replacing the severely worn filter screen 5 can keep the equipment running normally, avoid performance degradation or failures caused by aging or wear, and ensure the treatment efficiency and effluent quality of the sewage treatment system.
