Description

Technical Field

[0001] The invention relates to the technical field of air purification, in particular to a filtering device for air dust. Background Art

[0002] Air filter devices are widely used in indoor air purification, industrial emission control, clean rooms and other fields. Air filter devices can remove particulate matter, bacteria, viruses and harmful gases in the air, improve air quality and protect human health. The Chinese patent application with application number 202410056951.4 discloses "an air filter device and an air conditioner, wherein the air filter device includes a frame body, a through hole is opened in the middle of the frame body, and a plurality of filter elements are arranged in the through hole, and the plurality of filter elements are spherical. By setting the filter element to be spherical, the contact area between the filter element and the air is increased, and the filtering effect of the air filter device can be improved in a limited space, thereby improving the user experience";

[0047] Working principle: When the present invention is in use, the main control device 7 controls the start of the dual-axis motor 509, and the dual-axis motor 509 drives the second transmission gear 510 to rotate. When the second transmission gear 510 rotates, the gear ring 209 is driven to rotate, so that the rotating plate 208 follows the gear ring 209 to rotate on the fixed plate 207. When the fixed plate 207 rotates, the reciprocating plate 210 drives the suction plate 206 to reciprocate between the first mounting plate 411 and the air cylinder 203;

[0048] When the suction plate 206 moves away from the air cylinder 203, the suction rod 205 drives the piston 204 to move away from the suction box 202 in the air cylinder 203 through the movement of the suction plate 206. At the same time, the clamping plate 404 is in a vertical state. After the clamping plate 404 contacts the rear end of the translation plate 306, the translation plate 306 is driven to move away from the suction bucket 201, and then the rack 305 is driven to move by the translation plate 306. , the rack 305 drives the first transmission gear 304 to rotate, so that the door shaft 302 rotates with the first transmission gear 304, and drives the two door panels 303 to rotate respectively toward the upper air outlet pipe 307 and the lower air outlet pipe 308. At this time, the piston 204 draws the outside air into the air cylinder 203 through the air suction hopper 201 and the air suction box 202, so that the outside air passes through the air inlet mesh plate 501 and then passes through the dust-proof and breathable belt 507 in the air suction hopper 201 and then enters the air cylinder 203 after dust-proof filtration;

[0049] When the air extraction plate 206 moves to the first mounting plate 411, the top plate 413 is inserted into the plate slot 402, driving the launch plate 405 to rotate, so that the connecting shaft 403 rotates with the launch plate 405, and the engaging plate 404 rotates with the connecting shaft 403. At this time, the engaging plate 404 changes from a vertical state to a horizontal state. At this time, the rear end of the translation plate 306 is not engaged with the engaging plate 404, and the translation plate 306 is reset under the elastic force of the second reset spring 409. 6 drives the rack 305 to reset, and drives the first transmission gear 304 to reverse through the rack 305, so that the two door panels 303 rotate toward the middle partition plate 301 at the same time. At this time, the air inlet of the air suction box 202 is closed, and the upper air outlet pipe 307 and the lower air outlet pipe 308 are connected with the air suction box 202. Thereafter, the air extraction plate 206 moves toward the air cylinder 203, and the air extraction plate 206 drives the piston 204 to push the air in the air cylinder 203 into the upper air outlet pipe 307 and the lower air outlet pipe 308;

[0050] When the dual-axis motor 509 is started, the upper driving roller 505 is driven to rotate through the belt 512, and the lower driving roller 506 is driven to rotate through the third transmission gear 511. The upper driving roller 505 and the lower driving roller 506 rotate simultaneously to drive the dust-proof breathable belt 507 to slowly move outside the upper tensioning roller 503, the lower tensioning roller 504 and the guide roller 604, and the dust-proof breathable belt 507 located in the suction hopper 201 filters the air, so that the dust in the air is blocked on the surface of the dust-proof breathable belt 507, and then the dust-proof breathable belt 507 carrying dust rotates into the cleaning box 601;

[0051] A non-toxic cleaning liquid is placed in the water tank 605, and then the liquid is pumped out by the water pump 606 using the water suction pipe 607, and then discharged into the annular water pipe 612 through the drain pipe 608. The liquid entering the annular water pipe 612 is sprayed through the water spray pipe 613 to the dust-proof and breathable belt 507 located on a section of the air inlet mesh plate 501, with the dust-carrying side facing downward. The dust-proof and breathable belt 507 is flushed with the liquid sprayed from the water spray pipe 613, so that the dust on the dust-proof and breathable belt 507 falls into the cleaning box 601 with the liquid, and the liquid mixed with dust is filtered through the filter layer 602, and the water pump 606 makes the water Negative pressure is generated in the box 605, and the negative pressure is used to draw the filtered liquid below the filter layer 602 into the water tank 605 again through the water pipe 609 for recycling. While the water spray pipe 613 sprays water to clean the dust-proof and breathable belt 507, the gas guided out of the lower air outlet pipe 308 enters the jet bucket 610, and then sprays toward the dust-proof and breathable belt 507 through the jet hole 611. The dust on the dust-proof and breathable belt 507 is blown away from the dust-proof and breathable belt 507 by the jet, further improving the cleaning ability of the dust-proof and breathable belt 507, so that the dust-proof and breathable belt 507 can effectively maintain the air dust filtering effect for a long time.

[0052] The gas entering the upper air outlet pipe 307 is guided to the air inlet groove 412, and the filtered air guided out of the upper air outlet pipe 307 is discharged through the fan 515. The fan 515 blows the air through the air outlet groove 514 on the second mounting plate 513 to the dust-proof and breathable belt 507. The dust-proof and breathable belt 507 here is in a moist state after cleaning. The air is blown to the dust-proof and breathable belt 507 so that the moisture on the dust-proof and breathable belt 507 is discharged together with the air, so that the air drawn into the outer shell 1 is converted into moist clean air after dust filtering and is discharged from the outer shell 1 through the air outlet mesh plate 502. Not only the air is purified, but also the environmental humidity is increased, dust in the environmental air is prevented from being raised, and the indoor air purification effect is improved.
