In the present embodiment, the driving mechanism is a motor 200, and the motor 200 drives one of the rollers to rotate, for example, drives the lower roller to rotate.
When dust removal is needed, the motor 200 is started, the motor 200 drives the drum at the rear side to rotate clockwise, the drum drives the drum at the upper side to rotate clockwise through the inner-layer filter belt 240, and the inner-layer filter belt 240 drives the outer-layer filter belt 230 to rotate synchronously under the action of friction force. As shown in fig. 2, the dust-laden air is blown from right to left, when the inner filter belt 240 rotates, the first support column 310 of the second adjusting mechanism is driven to rotate by friction, the first support column 310 drives the first gear 340 to rotate clockwise, the first gear 340 drives the second gear 350 to rotate counterclockwise, and the second gear 350 drives the axial fan 360 to rotate counterclockwise. Because the limiting column 440 is clamped into the limiting sliding groove of the limiting connecting block 410 in the initial state, the sliding block 400 on the front side is fixed, the first supporting column 310 of the first adjusting mechanism cannot rotate and slips with the inner-layer filter belt 240, the two layers of filter belts are always kept aligned with the filter holes on the windward side under the effect of the adjusting mechanism and the filter hole spacing, and the filter holes of the two layers of filter belts are staggered on the leeward side. So that when the dust-carrying gas is discharged, the dust-carrying gas is subjected to two-stage filtration, the filtration precision of dust in the air is gradually increased, and the filtration effect is better.
The dust particles after primary filtration are carried to the direction of the filter cartridge 210 at the rear side under the action of the filter belt, and then are brushed off from the filter belt by the cleaning brush 250, and the axial flow fan 360 rotates counterclockwise, so that the dust particles which cannot be brushed off by the cleaning brush 250 in the filter holes on the filter belt are blown off and then fall into the dust collector 260. Dust particles attached to the filter belt after the second stage filtration are transferred to the filter cartridge 210 at the front side, and then enter the interior of the filter cartridge 210 at the front side through the leak holes on the filter cartridge 210 at the front side for collection, and part of the dust which does not follow the filter belt and enter the filter cartridge 210 freely falls into the collection chamber of the collection box 500.
When dust on the filter belt is cleaned after dust removal, the limiting column 440 is detached, the limiting column 440 is enabled not to limit the sliding block 400 on the front side any more, the inner-layer filter belt 240 can drive the first supporting column 310 of the first adjusting mechanism to rotate through friction force when rotating, the first supporting column 310 drives the cam 460 to rotate, the cam 460 drives the sliding block 400 on the front side to slide left and right, the sliding block 400 on the front side drives the sliding block 400 on the lower side to slide synchronously through the connecting rod 420 when sliding in left and right directions, each sliding block 400 drives the winding column 320 on the sliding block 400 to move synchronously, the inner-layer filter belt and the outer-layer filter belt are staggered, non-coincident parts of filter holes in the two layers of filter belts are scraped, and the device is convenient to clean.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.

after the dust removal work is finished, when dust on the filter belt is cleaned, the limiting columns are detached, the limiting columns are enabled not to limit sliding blocks on the front side any more, the inner layer filter belt can drive the first supporting columns of the first adjusting mechanism to rotate through friction force when rotating, the first supporting columns drive the cam to rotate, the cam drives the sliding blocks on the front side to slide in the left-right direction, the sliding blocks on the front side drive sliding blocks on the lower side to slide in the left-right direction through the connecting rods when sliding in the left-right direction, each sliding block drives the winding columns on the sliding blocks to synchronously move, the inner layer filter belt and the outer layer filter belt are enabled to be staggered, and non-coincident parts of filter holes in the two layers of filter belts are scraped.
2. A filter belt air cleaning apparatus according to claim 1, wherein: the roller is a filter cartridge, a plurality of leak holes are uniformly distributed on the peripheral wall of the filter cartridge, the filter belt type air dust removal device further comprises a dust removal mechanism, and the dust removal mechanism comprises a cleaning fan, a transmission assembly and a collection box; the cleaning fan is an axial flow fan, and a central shaft of the axial flow fan is rotatably arranged on the shell and is coaxial with one filter cartridge; the transmission assembly is configured to transmit the rotation of the first support column of the second adjusting mechanism to a central shaft of the axial flow fan; the collecting box is arranged on the shell and is positioned below the double-layer filter belt.
3. A filter belt air cleaning apparatus according to claim 2, wherein: the transmission assembly comprises a first gear and a second gear, the first gear is fixedly installed on a central shaft of the axial flow fan, and the second gear is fixedly sleeved on the first supporting column of the second adjusting mechanism and meshed with the first gear.
4. A filter belt air cleaning apparatus according to claim 1, wherein: the cleaning mechanism further comprises at least one cleaning brush which is fixedly arranged on the shell and used for cleaning the outer surface of the filter cylinder.
5. A filter belt type air dust removing device according to claim 1, wherein: still install a spacing connecting block on the sliding block that is provided with spacing hole, spacing connecting block sets up along the first direction, be provided with the spacing spout that extends along its length direction on the spacing connecting block, the cam is in on the second direction under the initial condition, and the cam is kept away from first support column one end and is inserted spacing spout through the inserted bar.
6. A filter belt air cleaning apparatus according to claim 1, wherein: the driving mechanism is a motor, and the motor drives a roller to rotate.
