The raised strips 6 are arranged in multiple groups. A collecting bin 5 is slidably connected to one side and opposite to the receiving assembly 2 , and a baffle plate with a built-in scroll spring is provided at the connection between the housing 1 and the collecting bin 5 .

Working principle: when in use, when the ventilation air sterilization treatment equipment is working, the outdoor air is sucked in. First, the outdoor air enters the inside of the housing 1. At this time, the air passes through the filter plate 44, and the filter plate 44 will The large-diameter impurities in the air are filtered, and then the air is filtered by the subsequent air treatment equipment. When the filter plate 44 continues to filter the air, some large-diameter impurities will gradually accumulate on the upper surface of the filter plate 44. As the large-diameter The accumulation of impurities reduces the efficiency of air passing through the filter plate 44. At this time, the driver 75 is started, and the collection bin 5 is pushed into the interior of the housing 1. The driver 75 pulls the filter plate 44 in the housing through the pull rope 71. 1 slides downwards, and at the same time the filter plate 44 pushes the reset telescopic plate 72 to compress the reset telescopic plate 72.

When the filter plate 44 slides downward inside the housing 1, and when the filter plate 44 is in contact with the protrusions 6 on the inner surface of the housing 1, the filter plate 44 slides horizontally inside the housing 1, shrinking the slide plate 441 A certain distance to the inside of the filter plate 44, while the slide plate 441 compresses the limit spring 442 inside the filter plate 44, when the filter plate 44 is far away from the convex strip 6, under the action of the elastic force of the limit spring 442 itself, the filter plate is pushed 44 slides on the outer surface of the slide plate 441. At this time, when the filter plate 44 slides downward inside the housing 1, the filter plate 44 itself will vibrate. The flocculent impurities shake, and when the filter plate 44 slides downward inside the housing 1, under the action of the traction member 42, the cleaning plate 41 slides inside the limiting groove 45 on the fixing plate 43, and the cleaning plate 41 is cleaned at this time. When the plate 41 slides inside the limit groove 45, the cleaning plate 41 will clean up the impurities on the upper surface of the filter plate 44, and the shaking of the filter plate 44 can prevent the flocculent impurities from being cleaned by the cleaning plate 41 during the cleaning process. 41 is squeezed on its lower surface, so that the cleaning plate 41 can clean up the impurities filtered on the filter plate 44 more thoroughly. The push rod set on the top can push the baffle plate set on the slag discharge hole in advance, so that the cleaned impurities can smoothly enter the collecting drawer 22 inside the fixed shell 21 through the connecting pipe 23, so as to facilitate the subsequent cleaning by the staff. The impurities that come out are processed in a centralized manner;

Simultaneously, when the cleaning plate 41 slides inside the limit groove 45, when the push rod 412 on the cleaning plate 41 slides along with the cleaning plate 41, under the elastic force of the return spring 413 itself, some of them will be stuck in the filter. The granular impurities in the holes on the plate 44 are cleaned out from the filter plate 44. When the cleaning plate 41 slides inside the limit groove 45, the connecting rod 411 on the cleaning plate 41 slides inside the guide groove 46, and the guide The track of the groove 46 is set with ups and downs. When the cleaning plate 41 slides away from the hole on the filter plate 44, the push rod 412 is lifted from the upper end hole of the filter plate 44 in time through the connecting rod 411. While the granular impurities in the holes on the plate 44 are being cleaned, the ejector rod 412 is prevented from engaging in the upper hole of the filter plate 44, which affects the normal sliding of the cleaning plate 41 on the upper surface of the filter plate 44, and avoids affecting the normal cleaning of the cleaning plate 41. Work.
