[0002] Air pollution is a phenomenon in which certain substances enter the atmosphere due to human activities or natural processes, present in sufficient concentrations and for a sufficient period of time, thereby endangering human comfort, health and welfare or the environment.

When the fine filter cartridge rotates 30°, the oscillation spring is in a compressed state, and the fine filter cartridge stops rotating. At this time, the electromagnet is powered off, and the oscillation spring drives the fine filter cartridge to gradually reset; Step 3: When there are a lot of impurities accumulated inside the base, start the extraction pump, which will extract the impurities inside the base through the extraction holes on the extraction ring tube, and the staff will collect them.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The air pollution filtering, adsorption and prevention equipment disclosed in the present invention is mainly applied to the existing air pollution filtering, adsorption and prevention equipment. During use, since the impurities carried in the air include large particles and small dust, when filtering and adsorbing them through the filter cartridge, the large particles of impurities are easily attached to the inner wall of the filter cartridge, thereby clogging the filter holes, resulting in poor air flow and affecting the filtering efficiency. At the same time, when a single filter cartridge is used to perform filtering operations, the cleaning and maintenance cycle required for the filter cartridge is very short, which will increase the investment in labor costs.

[0033] Reference Figure 1-Figure 11, an atmospheric pollution filtering, adsorption and prevention equipment, comprises a base 1, the top of the base 1 is fixedly connected with mounting rods 5 at equal distances, and the ends of the plurality of mounting rods 5 are provided with a same double-layer filtering mechanism 4, the double-layer filtering mechanism 4 comprises a fixed ring plate 401, and the fixed ring plate 401 is fixedly connected to the ends of the plurality of mounting rods 5, the bottom of the fixed ring plate 401 is provided with two annular grooves, the inner sliding connection of the annular groove located on the outer side is provided with an annular sliding rod 1 404, the bottom of the annular sliding rod 1 404 is fixedly connected with a fine filter cartridge 402, the inner sliding connection of the annular groove located on the inner side is provided with an annular sliding rod 2 411, the bottom of the annular sliding rod 2 411 is fixedly connected with a coarse filter cartridge 403, an auxiliary mechanism 8 is placed inside the coarse filter cartridge 403, and the top of the fixed ring plate 401 is fixedly connected with support rods 2 at equal distances, and the tops of the plurality of support rods 2 are provided with a same self-adjusting exhaust mechanism 3.

[0034] In a specific application scenario, when filtering impurities in the air, large particles of impurities are first filtered through the inner coarse filter cartridge 403. During the filtering process, the auxiliary mechanism 8 removes the large particles of impurities attached to the inner wall of the coarse filter cartridge 403 to prevent the filter holes on the coarse filter cartridge 403 from being blocked. The filter holes on the coarse filter cartridge 403 have a larger diameter, and small dust can pass through quickly, thereby improving the air filtration efficiency. At the same time, when the small dust and air flow between the coarse filter cartridge 403 and the fine filter cartridge 402, the rotation of the coarse filter cartridge 403 drives the fine filter cartridge 402 to rotate. Both the coarse filter cartridge 403 and the fine filter cartridge 402 are in an oscillating state, thereby preventing small dust from adhering to the fine filter cartridge 402 and causing poor air circulation, thereby improving the air filtration efficiency and filtering effect.

[0035] Specifically, at regular intervals, the electromagnet 414 is energized, and the electromagnet 414 adsorbs the docking iron ring 405, driving the motor 406 to drive the coarse filter cartridge 403 to rotate. During the rotation of the coarse filter cartridge 403, the pressing spring rod 419 drives the pressing block 413 to closely contact the inner wall of the fine filter cartridge 402, thereby driving the fine filter cartridge 402 to rotate accordingly. After the fine filter cartridge 402 rotates 30°, the oscillation spring 412 is in a compressed state, and the fine filter cartridge 402 stops rotating. After the motor 406 drives the coarse filter cartridge 403 to rotate for a short period of time, most of the impurities attached to the inside and outside of the coarse filter cartridge 403 fall off, and there is no need for manual maintenance of the coarse filter cartridge 403. At this time, the electromagnet 414 is powered off, and the oscillation spring 412 drives the fine filter cartridge 402 to gradually reset. During the resetting process, the fine filter cartridge 402 is in a state of reciprocating adjustment and oscillation, so that the small dust attached to the inner wall of the fine filter cartridge 402 gradually falls off, completing the maintenance of the fine filter cartridge 402 and reducing the investment in labor costs.

[0036] It should be noted that when the fine filter cartridge 402 is in the process of reciprocating adjustment and oscillation, the oscillation block 416 on the elastic connecting rod 418 is in a state of continuous contact and knocking with the outer wall of the coarse filter cartridge 403, so that the coarse filter cartridge 403 enters the oscillation state at the same time as the fine filter cartridge 402, further improving the effect of removing impurities attached to the coarse filter cartridge 403.

[0038] Specifically, during the air filtering operation of the coarse filter cartridge 403 and the fine filter cartridge 402, the driving motor 406 drives the cleaning brush 805 on the back plate 803 to always clean the inner wall of the coarse filter cartridge 403 to prevent the adhesion of impurities from affecting the subsequent air circulation. During the cleaning process, the air compressor 806 is started, and the air compressor 806 introduces the air inside the coarse filter cartridge 403 into the jet ring cover 807, and sprays it to the inner wall of the coarse filter cartridge 403 through the jet hole 814, thereby accelerating the shedding and cleaning of impurities. At the same time, the air ejected from the jet hole 814 can quickly pass through the filter holes on the coarse filter cartridge 403 to complete the preliminary filtration of large particles of impurities and improve the filtration efficiency.

[0039] It should be noted that during the use of the equipment, the hydraulic cylinder 809 is adjusted to pull up the three-layer elastic mesh plate 801 at regular intervals, so that the mesh holes on the elastic mesh plate 801 are gradually enlarged, and the impurities on the three-layer elastic mesh plate 801 gradually fall into the base 1 below as the elastic mesh plate 801 rotates. Then the hydraulic cylinder 809 drives the three-layer elastic mesh plate 801 to reset, and the mesh holes on the three-layer elastic mesh plate 801 are staggered, thereby separating the impurities below from the space above, thereby preventing the impurities below from being attached to the inner wall of the coarse filter cartridge 403 for a second time and affecting the air filtration effect.
