When the filter screen 3 filters waste gas for a certain time, the driving motor 607 drives the driving shaft 602 to rotate, the driving shaft 602 drives the movable fins 605 to rotate, so that the movable fins 605 and the fixed fins 606 are completely dislocated, at the moment, the movable fins 605 and the fixed fins 606 are mutually matched to block the air duct 204, the air duct 204 is in a disconnected state, meanwhile, the driving shaft 602 drives a plurality of driven shafts 601 to synchronously rotate through the bevel gear set 608, the driven shafts 601 drive the rotating plates 604 to synchronously rotate, the rotating plates 604 are in an inclined state in the air vent grooves 603, the rotating plates 604 do not block the air vent grooves 603, the air vent grooves 603 are in an open state, and waste gas is not introduced into the filter screen 3 to carry out filtering operation.
Then, the second air pump 501 pumps air in the filter screen 3 through the air exhaust pipe 502, so that external air is pumped into the filter screen 3 from outside to inside, and in the process that the external air enters the filter screen 3 from outside to inside, the external air can impact the filter screen 3, particles in meshes on the filter screen 3 are backflushed out of the meshes, the backflushed particles and the particles originally accumulated in the ventilation groove 603 are pumped into the air exhaust pipe 502, and the particles stay in the air exhaust pipe 502 under the blocking effect of the filter plate 507.
After the backflushing cleaning of the filter screen 3 is completed and all the particles in the filter screen 3 are extracted into the exhaust pipe 502, the airflow control assembly 6 is adjusted to be in an initial state, the air duct 204 is in a communicating state again, the air duct 603 is in a closed state again, waste gas can be introduced into the filter screen 3 again at the moment and the filtering treatment can be carried out, meanwhile, the second air pump 501 is adjusted to be in an air blowing state, the second air pump 501 carries out backflushing treatment on the filter plate 507, and the particles in the exhaust pipe 502 are blown into the collecting hopper 505 through the discharge pipe 504, so that the filtering and collecting treatment on the particles in the waste gas is completed.
In the second embodiment, in the above embodiment, two groups of filter screens 3 are provided to filter the exhaust gas, and the second air pump 501 is used to collect the exhaust gas particulate matters in the filter screens 3 and clean the filter screens 3; simultaneously, through the air current control assembly 6 to the operating condition of two sets of filter screens 3 carry out the individual regulation, make two sets of filter screens 3 can freely switch between filtration and clearance state to this reaches the purpose that filters and clearance work goes on simultaneously, realizes carrying out the effect of recoil clearance to another filter screen 3 when one filter screen 3 carries out the filtration work, improves the filtration ability of filter screen 3 when guaranteeing filtration efficiency.
However, since the filter screen 3 is configured as a multi-layer tubular structure with inner and outer sleeves, in the process of filtering the exhaust gas, the exhaust gas particulate matters are filtered by the filter screen 3 of the innermost layer preferentially, that is, the filter pressure born by the filter screen 3 of the innermost layer is greater than the filter pressure born by the filter screen 3 of the outer layer, which results in that the mesh holes on the filter screen 3 of the innermost layer are easier to be blocked than the filter screen 3 of the outer layer. In the above embodiment, when the air flow generated by the second air pump 501 is used for cleaning the mesh openings of the filter screen 3 in a backflushing manner, the air flow will preferentially clean the outer filter screen 3 in a backflushing manner, and when the air flow passes through the multi-layer filter screen 3 to reach the innermost filter screen 3, the backflushing force is reduced to a smaller extent, and sufficient force cannot be provided for cleaning the mesh openings of the innermost filter screen 3; meanwhile, when the meshes are completely blocked, the airflow can pass through the unobstructed meshes preferentially, the blocked meshes cannot be dredged, and for some meshes with serious blocking degree, the dredging and cleaning can not be carried out only by the recoil of the airflow. Therefore, based on the above problems, the scheme of the invention is further improved, so that in the process of filtering and cleaning simultaneously, enough airflow impact force can be provided for all meshes, thereby ensuring the dredging and cleaning effects on the meshes with blockage, meanwhile, in the process of dredging and cleaning, the filter screen 3 is continuously vibrated to a certain extent, and the meshes with severe blockage are dredged and cleaned by matching with the impact of airflow, so that the cleaning effect on the filter screen 3 is improved.
Specifically, as shown in fig. 1 to 16, an auxiliary cleaning assembly 7 is disposed in the chassis 1, the auxiliary cleaning assembly 7 includes a swinging grille 701, an elastic plate 702 and a supporting frame 703, a louver 704 is disposed in the middle of the partition 102, the louver 704 communicates two side spaces of the partition 102, the swinging grille 701 is provided with a plurality of swinging grilles, the swinging grilles 701 are uniformly rotated and disposed in the louver 704, the swinging grilles 701 are mutually matched to change an opening and closing state of the louver 704, the number of the elastic plates 702 is plural, the elastic plates 702 are uniformly fixed on the outer sides of the two filter screens 3, the side surfaces of each elastic plate 702 are cambered surfaces, the number of the supporting frames 703 is two, and the two supporting frames 703 are symmetrically fixed on the inner wall of the chassis 1.
More specifically, a reset torsion spring is arranged between the bottom end of the swing grille 701 and the ventilation window 704, the reset torsion spring can limit the maximum angle of rotation of the swing grille 701, the side surface of the supporting frame 703 is set to be an arc surface matched with the elastic plate 702, when the elastic plate 702 passes through the supporting frame 703, the supporting frame 703 can support the elastic plate 702, and the elastic plate 702 is forced to deform to a certain extent.
It should be noted that, when the angles of the plurality of swing gratings 701 do not swing, the adjacent swing gratings 701 are mutually attached to each other, so that the ventilation window 704 is in a closed state, at this time, the spaces at two sides of the partition board 102 are mutually independent, the air in the spaces at two sides cannot flow through each other, when the angles of the plurality of swing gratings 701 swing, a gap is formed between the adjacent swing gratings 701, so that the ventilation window 704 is in an open state, at this time, the spaces at two sides of the partition board 102 are mutually communicated, the air in the spaces at two sides also flow through each other, and due to the reset torsion spring, the maximum angle that can be rotated when the swing gratings 701 swing is limited, that is, when the swing gratings 701 rotate for a certain angle, the swing gratings 701 at this time are in an inclined state, and the air guided by the swing gratings 701 is blown from one side to the other side of the partition board 102 at a certain inclination angle.
Specifically, the air duct 204 and the air inlet pipe 402 can rotate relatively, and the air duct 204 and the air inlet pipe 402 are tightly attached to each other, so as to ensure tightness between the two.
