Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a sewage tank filter net that is convenient to replace. Background Technique

[0002] The sewage tank filter net is a key device used in the sewage treatment process. Its main function is to separate and remove suspended solids, solid particles, colloids, bacteria and other impurities in the sewage to improve the sewage treatment effect. The sewage tank filter net intercepts and removes impurities in the sewage through its specific filtering media (such as sieve meshes, microporous filter nets, membrane filter nets, etc.). These filter nets can not only effectively remove suspended solids and solid particles in the sewage, but also remove microorganisms such as bacteria and viruses to a certain extent, thereby improving the cleanliness of the sewage and the quality of the treated water.

[0003] The patent with the publication number CN218046909U discloses a cleanable filter net for a sewage sedimentation tank, including a sedimentation tank. A sedimentation area is arranged at the lower left side inside the sedimentation tank. A sewage discharge pipe is connected to the left side of the sedimentation area. Support plates are welded to the right ends of the front and rear surfaces of the sedimentation tank. A motor is fixedly installed on the upper surface of the support plate. The output shaft of the motor is coaxially connected with a transmission belt pulley. An outlet pipe is fixedly installed on the right surface outside the sedimentation tank. Fixing mechanisms are welded to both ends of the right inner surface of the sedimentation tank. A filter frame is slidably connected between the fixing mechanisms. A cleaning mechanism is slidably connected inside the fixing mechanism; the cleaning mechanism can regularly clean the filter frame in the sedimentation tank to prevent the accumulation of filter substances from affecting the normal use of the filter frame. The inserted filter frame can be replaced more conveniently when the filter frame is damaged or the aperture of the filter net inside the filter frame is inappropriate.

[0004] Although this device has many beneficial effects, there are still the following problems: The filter net is replaced by plugging. Although the convenience of replacement is improved to a certain extent, plug-in connections usually rely on the precise matching between the filter net and the slot. If the thickness of the filter net changes, it may cause the filter net to not be inserted into the slot correctly, or the seal is not tight after insertion. Summary of the Utility Model

[0030] Four groups of connection components, which are symmetrically distributed on both sides of the sewage treatment tank 1 and are used to connect the filter screen body 5 to the sewage treatment tank 1;

[0031] A mobile cleaning component, which is located on the outer surface of the filter screen body 5 and is used to clean the filter screen body 5. Sewage enters the sewage treatment tank 1 through the water inlet 3. Through the filtering action of the filter screen body 5, suspended solids, solid particles and other impurities are removed. The filtered clean water is discharged through the water outlet 2. The valves 4 of the water outlet 2 and the water inlet 3 can control the inflow and outflow of sewage as needed.

[0032] Further, the connection component includes a fixed block 7, a moving column 8 and a return spring 16. The outer surface of the sewage treatment tank 1 is fixedly connected to the fixed block 7. The inside of the fixed block 7 is movably connected to the moving column 8. The moving column 8 is inserted into the outer surface of the sewage treatment tank 1. A return spring 16 is sleeved on the outer surface of the moving column 8. The return spring 16 is located inside the fixed block 7. By applying an external force to push the moving column 8, it overcomes the elastic force of the return spring 16 and moves outwards from the fixed block 7, so that the moving column 8 disengages from the connection hole 6, and the filter screen body 5 is no longer connected to the sewage treatment tank 1.

[0033] Further, two symmetrically distributed connection holes 6 are opened on the outer surfaces of both sides of the filter screen body 5. The moving column 8 is movably connected to the connection hole 6. When installing a new filter screen body 5, align the two sides of the filter screen body 5 and approach the inner wall of the sewage treatment tank 1 to align the connection hole 6 with the moving column 8.

[0034] Further, four symmetrically distributed limiting plates 10 are fixedly connected to the inner wall of the sewage treatment tank 1. The outer surfaces of the four limiting plates 10 are movably connected to the filter screen body 5. The four limiting plates 10 provide additional support and positioning to ensure the stability of the filter screen body 5.

[0035] Furthermore, the mobile cleaning assembly includes a driving motor 9, a cleaning frame 12, a connecting frame 14, and a threaded rod 15. The inner wall of the sewage treatment tank 1 is fixedly connected with the connecting frame 14. The threaded rod 15 is rotatably connected inside the connecting frame 14. The driving motor 9 is fixedly installed at the top of the connecting frame 14. The output end of the driving motor 9 is fixedly connected with the end of the threaded rod 15. The cleaning frame 12 is sleeved on the outer surface of the threaded rod 15. A rectangular groove is formed on the outer surface of the connecting frame 14. The cleaning frame 12 is slidably connected with the rectangular groove. The rotation of the driving motor 9 drives the threaded rod 15 to rotate inside the connecting frame 14. Since the cleaning frame 12 is threadedly connected with the threaded rod 15.

[0036] Furthermore, a guide rail 11 is fixedly connected to the inner wall on the other side of the sewage treatment tank 1. The guide rail 11 is slidably connected with the cleaning frame 12. By being slidably connected with the connecting frame 14 through the rectangular groove, the rotation of the threaded rod 15 will drive the cleaning frame 12 to move inside the sewage treatment tank 1 along the guide rail 11 and inside the rectangular groove.

[0037] Furthermore, a plurality of equally spaced cleaning columns 13 are fixedly connected to the outer surface of the cleaning frame 12 close to the filter net body 5. The plurality of cleaning columns 13 are movably connected to the inside of the filter net body 5. As the cleaning frame 12 moves, the cleaning columns 13 will brush or scrape the inner surface of the filter net body 5, thereby removing the impurities attached to it.

[0038] Working principle: When the staff needs to use the sewage tank filter screen that is easy to replace, sewage enters the sewage treatment tank 1 through the water inlet 3. Through the filtering effect of the filter screen body 5, suspended solids, solid particles and other impurities are removed. The filtered clean water is discharged through the water outlet 2. The valves 4 at the water outlet 2 and the water inlet 3 can control the inflow and outflow of sewage as needed. When the filter screen body 5 needs to be replaced, the moving column 8 is pushed by an external force to overcome the elastic force of the return spring 16 and move outwards from the fixed block 7, so that the moving column 8 disengages from the connecting hole 6, and the filter screen body 5 is no longer connected to the sewage treatment tank 1. Then, a new filter screen body 5 is installed. Align the two sides of the filter screen body 5 and approach the inner wall of the sewage treatment tank 1, align the connecting hole 6 with the moving column 8, release the moving column 8, and the elastic force of the return spring 16 pushes the moving column 8 into the connecting hole 6, thereby fixing the filter screen body 5 in the sewage treatment tank 1. The outer surface of the filter screen body 5 is movably connected to the four limiting plates 10, providing additional support and positioning to ensure the stability of the filter screen body 5. When a certain amount of impurities accumulate on the filter screen body 5 and need to be cleaned, the driving motor 9 is started. The rotation of the driving motor 9 drives the threaded rod 15 to rotate inside the connecting frame 14. Since the cleaning frame 12 is threadedly connected to the threaded rod 15 and slidably connected to the connecting frame 14 through the rectangular groove, the rotation of the threaded rod 15 will drive the cleaning frame 12 to move inside the sewage treatment tank 1 along the guide rail 11 and inside the rectangular groove. As the cleaning frame 12 moves, the cleaning column 13 will brush or scrape the inner surface of the filter screen body 5 to remove the impurities attached to it. After the cleaning is completed, the driving motor 9 is turned off, and the cleaning frame 12 stays at the initial position or is adjusted to other positions as needed, so as not to interfere with the work of the filter screen body 5.
