Different filtering media can effectively filter impurities in sewage, thereby achieving the effect of purifying sewage, and the filtered impurities will adhere to the filtering media.

[0003] When traditional filters filter sewage, most of them use a single filtering medium to filter sewage, resulting in a general purity of the filtered sewage, and some cannot meet the ideal requirements. At the same time, after filtration, the impurities are on the filtering medium and are not easy to remove for treatment. Therefore, a filter with a multi-stage filtering device is proposed to solve the above-mentioned problems. Content of the Utility Model

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , a filter with a multi-stage filtering device in this embodiment includes a base 1. The top of the base 1 is threadedly connected to a filter cartridge 2. The top of the filter cartridge 2 is fixedly installed with an intake pipe 3. The bottom of the base 1 is provided with an air outlet 4. An adjustment assembly 5 is installed inside the filter cartridge 2.

[0023] Specifically, the gas enters the filter cartridge 2 through the intake pipe 3, is filtered by the multi-stage filtering assembly 6, and then discharged through the air outlet 4.

[0024] A multi-stage filtering assembly 6 is installed inside the filter cartridge 2. The multi-stage filtering assembly 6 includes brackets 601 movably installed on the left and right inner walls of the filter cartridge 2. On the opposite sides of the two brackets 601, cross plates 602 are fixedly installed. On the tops of the two cross plates 602, return springs 603 are fixedly installed. Between the tops of the two return springs 603, a primary filter screen 604 is fixedly installed. A secondary filter screen 605 and a tertiary filter screen 606 are respectively fixedly installed between the two brackets 601.

[0025] Specifically, impurities inside the gas are filtered by the primary filter screen 604, the secondary filter screen 605, and the tertiary filter screen 606 respectively, and the effect of multi-stage filtering can be achieved.

[0026] The adjustment assembly 5 includes a rotating rod 501 rotatably installed on the front and rear inner walls of the filter cylinder 2. A turntable 502 is fixedly installed on the outer surface of the rotating rod 501, and a fan blade 503 is fixedly installed on the outer surface of the rotating rod 501. A connecting rod 504 is rotatably installed on the outer surface of the turntable 502. A rotating shaft 505 is rotatably installed on the inner wall of the filter cylinder 2. A sector gear 506 is fixedly installed on the outer surface of the rotating shaft 505. A fixed cylinder 507 is fixedly installed on the right inner wall of the filter cylinder 2. A knocking hammer 508 is slidably installed inside the fixed cylinder 507. A toothed plate 509 is fixedly installed on the outer surface of the knocking hammer 508.

[0027] Specifically, due to the strong impact force of the gas, it will drive the rotating rod 501, the fan blade 503 and the turntable 502 to rotate. The rotation of the turntable 502 will drive the sector gear 506 to rotate through the connecting rod 504, thereby driving the knocking hammer 508 to reciprocate up and down, knocking on the primary filter screen 604 to prevent the primary filter screen 604 from being blocked and improving the filtration efficiency.

[0028] The top of the base 1 extends into the filter cylinder 2, and both the left and right ends of the top of the base 1 abut against the bottom of the bracket 601.

[0029] Specifically, after long-term use, the base 1 can be twisted to disassemble the base 1 from the filter cylinder 2, so that the multi-stage filtration assembly 6 is separated from the filter cylinder 2, and then the multi-stage filtration assembly 6 can be cleaned.

[0030] In summary, for the filter with a multi-stage filtration device, through the cooperation of the filter cylinder 2, the air inlet pipe 3, the multi-stage filtration assembly 6 and the air outlet 4, the gas enters the filter cylinder 2 through the air inlet pipe 3, and the impurities in the gas are filtered by the primary filter screen 604, the secondary filter screen 605 and the tertiary filter screen 606 respectively, achieving the effect of multi-stage filtration.

[0031] Moreover, by setting the adjustment assembly 5, when the gas enters the filter cylinder 2 through the air inlet pipe 3, due to the strong impact force of the gas, it will drive the rotating rod 501, the fan blade 503 and the turntable 502 to rotate. Therefore, the rotation of the turntable 502 will drive the sector gear 506 to rotate through the connecting rod 504. Due to the meshing relationship between the sector gear 506 and the toothed plate 509, the rotation of the sector gear 506 will push the toothed plate 509 to move up and down, and the toothed plate 509 drives the knocking hammer 508 to reciprocate up and down, thereby knocking on the primary filter screen 604 to prevent the primary filter screen 604 from being blocked and improving the filtration efficiency.
