Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and specifically to an efficient sewage treatment device for preventing filter screens from being blocked. Background Art

[0002] Sewage treatment: The process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it; sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people.

[0003] Existing sewage needs to be treated to prevent direct discharge and pollution of the environment. In addition to invisible pollutants, there are also various visible sundries in the sewage. The sundries need to be filtered, and then the invisible pollutants in the sewage are subjected to subsequent treatment. Filtration is generally carried out through a filter screen. During long-term filtration, the sundries remain on the filter screen, which easily causes the filter screen to be blocked. Therefore, during the entire filtration process, the filtration efficiency of the sewage gradually decreases until filtration can no longer be carried out at all. At this time, the sewage inlet pipe needs to be closed, and then the filter screen is disassembled, the filter screen is cleaned, and after completion, the filter screen is reset and then the filtration work continues. Repeating like this, when the filter screen is disassembled and cleaned, the filtration is in a stagnant state at this time, thereby reducing the filtration and treatment efficiency of the sewage. Therefore, there is an urgent need for a device to solve the above problems. Summary of the Invention

The box body 13 is fixed to the top of the first support frame 6 by bolts. The support bars 22 are welded and fixed to the inner side wall of the box body 13. There are two support bars 22, symmetrically installed on both sides inside the box body 13. The movable box 21 is slidably arranged on the top of the support bars 22. The support plate 26 is welded and fixed to the top of the box body 13. The sewage pipe 7 is embedded and fixed on one side of the support plate 26.

One side of the moving block 20 is welded and fixed to the movable box 21. The movable box 21 is composed of two boxes welded and fixed together. The rectangular hole 25 is opened at the lower end of the movable box 21. There are two rectangular holes 25, respectively opened at the bottom ends of the two boxes forming the movable box 21. The filter screen 23 is placed at the inner bottom end of the movable box 21. The mesh holes of the filter screen 23 are larger than those of the filter screen cylinder 9. The handle 24 is welded and fixed to the top of the filter screen 23. There are two handles 24, symmetrically installed on both sides at the top of the filter screen 23, facilitating the removal of the filter screen 23. When in use, sewage is injected into the inner side box of the movable box 21 through the sewage pipe 7, and the sewage is preliminarily filtered by the internal filter screen 23. The filtered sewage flows into the box body 13 through the rectangular hole 25, and then is injected into the filter screen cylinder 9 through the injection pipe 12 for subsequent filtering work. The second motor 18 is started regularly, so that the second motor 18 drives the screw rod 19 to rotate, thereby enabling the moving block 20 to move along the screw rod 19, driving the movable box 21 to move inside the box body 13 until the inner box of the adjacent movable box 21 moves to the lower end of the sewage pipe 7. Thus, the adjacent filter screens 23 are used for filtering.

After a period of time, the second motor 18 is rotated in the reverse direction to reset the filter screen 23, and then the filter screen 23 with debris is cleaned. This process is repeated.

[0030] Working principle: When in use, sewage is injected into the inner box on one side of the movable box 21 through the sewage pipe 7. The sewage is preliminarily filtered by the filter screen 23 inside. The filtered sewage flows into the inside of the box body 13 through the rectangular hole 25, and then is injected into the inside of the filter screen cylinder 9 through the injection pipe 12. The second motor 18 is started regularly, so that the second motor 18 drives the screw rod 19 to rotate, thereby making the moving block 20 move along the screw rod 19, driving the movable box 21 to move inside the box body 13 until the box inside the adjacent movable box 21 moves to the lower end of the sewage pipe 7. In this way, it is filtered by the adjacent filter screens 23. At this time, the filter screen 23 that has moved to the side far from the sewage pipe 7 can be disassembled and cleaned through the handle 24, ensuring the continuity of sewage filtration, thus ensuring the filtration efficiency. After the disassembly and cleaning are completed, the filter screen 23 is reset. After a period of time, the second motor 18 is rotated in the reverse direction to reset the filter screen 23, and then the filter screen 23 with sundries is cleaned. This is repeated;

[0031] When in use, the first motor 15 is started. The first motor 15 drives the gear 16 to rotate. In this way, the filter screen cylinder 9 is driven to rotate through the toothed ring 14. The sewage preliminarily filtered by the filtering mechanism is injected into the inside of the filter screen cylinder 9 through the injection pipe 12. Then the sewage flows into the inside of the recycling box 1 through the mesh holes of the filter screen cylinder 9, and the sundries remain inside the filter screen cylinder 9. When the filter screen cylinder 9 rotates, at this time, the sundries blocking the upper end of the filter screen cylinder 9 rotate to the upper end and fall to the lower end of the filter screen cylinder 9 under the action of gravity. This is repeated, and the mesh holes of the filter screen cylinder 9 cannot be completely blocked, so as to ensure that the filter screen cylinder 9 can always maintain the filtering effect during filtration and improve the filtration efficiency;

[0032] When in use, the electric push rod 5 is started regularly to make a reciprocating motion, driving the cleaning ring 10 to move inside the filter screen cylinder 9, scraping the sundries inside the filter screen cylinder 9, and then pushing them to the outside of the extension cylinder 11, and then falling into the storage box 3 for storage. The inside of the storage box 3 is cleaned regularly, so as to ensure the filtration efficiency of the filter screen cylinder 9 during long-term filtration.
