[0003] The patent with publication number CN111298546B discloses a waste gas dust removal cleaning device for atmospheric environment pollution prevention and control, which comprises a cleaning device shell, a lower water delivery pipe, a drive gear and an exhaust fan. The left side of the cleaning device shell is connected with an air inlet, and the upper side of the cleaning device shell is bolted with an upper mounting plate. The rear upper side of the upper mounting plate is threadedly connected with an upper water delivery pipe, and the upper water delivery pipe is connected with a circulating water pump through a connecting pipe. An adjusting pipe penetrates through the inside of the upper mounting plate, and the lower side of the adjusting pipe is connected with a lower mounting plate. The waste gas dust removal cleaning device controls the rotation of the drive gear to drive the rotation of the connecting ring mounted on the outer side of the filter plate, so as to control the rotation of the filter plate, adjust the contact surface between the filter plate and the waste gas, and clean the filter plate by using the cleaning brush in the cleaning groove while the filter plate is rotating. This can facilitate the continuous cleaning and filtering of the waste gas, and can clean and maintain the filter plate, thereby improving the convenience of using the device.

[0004] However, the filter material in the above-mentioned device may not be fully utilized during operation, which may cause uneven consumption of the filter material and affect the effective service life of the filter material. Therefore, the waste gas dust removal cleaning device for atmospheric environment pollution prevention and control is proposed to solve the above-mentioned problems. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a waste gas dust removal cleaning device for atmospheric environment pollution prevention and control to solve the above-mentioned problems in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a waste gas dust removal and cleaning device for atmospheric environmental pollution prevention and control, comprising a box body, a base installed at the bottom of the box body, a sleeve fixedly connected to the inner wall of the box body, a partition fixedly connected to the inner wall of the box body, a drive motor installed at the top of the partition, an exhaust fan installed at the top of the partition, a filter mechanism installed on the inner wall of the partition, a scraping mechanism provided inside the filter mechanism, and a sludge storage mechanism installed at the bottom of the box body. The filter mechanism includes: a filter element barrel, a gear ring, a threaded rod, a gear, a grid plate, a wedge block, a push rod, a roller, and a protrusion. The filter element barrel is rotatably connected to the inner wall of the partition, and the gear ring is fixedly connected to... On the circumferential surface of the filter cartridge, the threaded rod is rotatably connected to the inner wall of the partition plate, and the threaded rod is driven by a drive motor installed on the top of the partition plate. The gear is fixedly connected to the circumferential surface of the threaded rod. The grid plate is rotatably connected to the inner wall of the sleeve opening. The wedge block is slidably connected to the top of the sleeve. The push rod is slidably connected to the inner wall of the sleeve opening. The roller is rotatably connected to the inner wall of the top of the push rod. The protrusion is fixedly connected to the circumferential surface of the filter cartridge. The gear meshes with the gear ring. The push rod is movably connected to the grid plate. The roller is located on the movement trajectory of the wedge block. The threaded rod is driven by the drive motor. An air inlet is opened on the surface of the housing, and the sleeve opening is connected to the air inlet opened on the surface of the housing. The device operates by starting the exhaust fan, which draws in surrounding air through openings on the surface of the housing. The air is then filtered through the filter cartridge, trapping fine particles and pollutants on its surface. Clean air exits through the exhaust vent at the top of the housing. Simultaneously, a drive motor rotates a threaded rod, which in turn rotates a gear, which in turn rotates a meshing gear ring. This rotation of the filter cartridge causes it to rotate continuously and slowly, ensuring that the entire surface area of ​​the filter screen alternately faces the direction of highest polluted air concentration. This rotating design ensures very even consumption of the filter media, making full use of all the media until the entire filter cartridge is almost completely used up. When the filter reaches the end of its lifespan, the effective lifespan of the filter can be greatly extended. When the filter cartridge rotates, it also drives the protrusions to rotate. During the rotation of the protrusions, they will contact and squeeze the wedge blocks, causing the wedge blocks to move. As the wedge blocks move, their surfaces will contact and push the rollers upward. The upward movement of the rollers will drive the push rod upward, and the upward movement of the push rod will cause the grille to swing. After the protrusions move away from the wedge blocks, the push rod will fall back down due to gravity and drive the protrusions to reset. As the wedge blocks are continuously pushed by the protrusions, the grille will swing up and down, optimizing the air intake efficiency, maximizing the use of the filter, and further improving the purification effect. The swinging grille can also actively guide the suction port in different directions, reducing purification dead zones.

During the rotation of the threaded rod, the threads on the surface of the threaded rod also drive the sliding block to move downward, the downward movement of the sliding block drives the annular scraper to move downward, the downward movement of the annular scraper scrapes the impurities, dust and flocculation on the surface of the filter cartridge barrel, so that they fall to the top of the baffle, avoiding premature local blockage and helping to keep the filter cartridge barrel unobstructed. By keeping the filter cartridge unobstructed, the wind resistance is always within a reasonable range, and the air suction fan can always operate under the best working condition, thereby improving the reliability and durability of the entire purification system. When the sliding block drives the annular scraper to move downward, the mounting seat also moves, the movement of the mounting seat drives the internally threaded transmission wheel to move, the internally threaded transmission wheel starts to rotate under the constraint of the threaded rod, the rotation of the internally threaded transmission wheel drives the driven wheel in contact with it to rotate, the rotation of the driven wheel drives the rolling brush to rotate and washes the filter cartridge barrel. With the rotation of the filter cartridge barrel itself and the downward movement of the sliding block, the cleaning effect and coverage area of the blockage on the surface of the filter cartridge barrel are further improved.
