When the air filter is particularly used, ventilation air flow enters the ventilation pipe 3, the filter screen 9 intercepts dust particles in the entering air, the ventilation resistance is increased along with the increase of the blocking degree of the filter screen 9, the flow of the air passing through the filter screen 9 is reduced, according to the Bernoulli principle, under the condition of a certain flow, the pressure is increased due to the increase of the resistance, the front side pressure and the rear side pressure of the filter screen 9 generate pressure difference, the front side pressure and the rear side pressure of the filter screen 9 are increased, the filter screen 9 is pushed to slide in the sliding chute 7 to the rear side by the pressure difference, the filter screen 9 slides and drives the blocking plate 10 to move, the collection groove 5 is opened by the through groove 4 to be communicated with the ventilation pipe 3, the problem of instantaneous pressure relief is also avoided because the water solution 6 is filled in the collection groove 5, the air flow conveyed in the ventilation pipe 3 drives the blades 133 on the shaft sleeve 132 to rotate, the rotating blades 133 flap the filter screen 9 which moves backwards continuously, so that dust particles intercepted on the filter screen 9 are beaten, and when the filter screen 9 moves towards the frame 11 due to pressure difference, a reaction force is given to the filter screen 9 when the filter screen 9 contacts with the action rod 14 on the frame 11, the reaction force can also vibrate the filter screen 9, so that the dust particles on the filter screen 9 can shake off better, and meanwhile, the pressing rod 123 and the wedge block 124 are driven to move towards the high-pressure spray head 121 while the filter screen 9 is driven to move under the action of pressure, so that the contact valve 122 at the bottom side of the high-pressure spray head 121 is contacted, and the high-pressure spray head 121 is opened to spray high-pressure spray the filter screen 9 at the moment to reduce dust until the pressing rod 123 contacts with the contact valve 122;
The waste liquid after dust fall is sprayed back into the collecting tank 5, a small flow control pump is also arranged on the conveying pipe 17, when dust fall is sprayed next time, the pump on the conveying pipe 17 can pump the liquid collected in the collecting tank 5 into the centrifugal machine 16, the inside of the centrifugal machine 16 is subjected to high-speed rotation treatment, the components are separated due to different densities under the centrifugal force, solid impurities in the liquid are thrown to the wall of the centrifugal machine 16, water is reserved in the central area of the rotary drum, separated clean water is pumped by the pump body 20 and conveyed to the high-pressure spray head 121 through the drain pipe 18 for dust fall, the waste liquid after dust fall is collected into the collecting tank 5 again, and the recycling is realized, so that the water solution 6 in the collecting tank 5 is always kept in a full state;
According to the ventilation requirement, the air quantity of the air outlet of the ventilation pipe 3 is regulated, the driving motor 226 is started, the driving motor 226 drives the rotating shaft 227 to rotate, the rotating shaft 227 drives the worm 228 to rotate, the worm 228 drives the worm wheel 229 to rotate, the worm wheel 229 drives the wind shield 224 on the mounting shaft 223 to rotate, and the wind shield 224 is regulated to a proper angle so as to meet the ventilation requirement.
The invention and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the invention as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present invention.
