The application method and the working principle of the device are as follows: the air filter 1 is installed on a mining automobile, a second connecting pipe 26 is installed and connected with an air compression system of the automobile, an air outlet pipe 13 is installed and connected with the automobile, air enters the fixed shell 11 from the air inlet pipe 12 in the driving process of the mining automobile, the air is filtered through the filter element body 14 and then supplied to the automobile through the air outlet pipe 13, dust is gradually attached to the surface of the filter element body 14 in the air filtering process of the filter element body 14, and through holes on the surface of the filter element body 14 are blocked;
as the surface of the filter element body 14 is blocked more and more seriously, the air inlet resistance of the filter element body 14 is increased, so that the air inlet amount is reduced, the difference between the air inlet pressure at the end of the air outlet pipe 13 and the air inlet pressure at the end of the air inlet pipe 12 is gradually increased, when the pressure difference between the first pressure sensor 24 and the second pressure sensor 25 is detected to reach a set value of a control system, the control system opens the electromagnetic valve 27, the air compression system of the automobile injects compressed air into the air storage tank 21 through the second connecting pipe 26, when the pressure of the compressed air reaches a preset value, the control system starts the electromagnetic pulse valve 22, the compressed air is rapidly released into the purge air tank 28 through the first connecting pipe 23, the pressure in the purge air tank 28 is instantaneously increased, the first sealing plate 211 is pushed out from the surface of the purge air tank 28, meanwhile, the first spring 210 and the telescopic rod 29 are stretched, the compressed air can instantaneously impact into the filter element body 14, and the dust attached to the surface of the filter element body 14 is purged;
after the purging of the filter element body 14 is completed, the first spring 210 and the telescopic rod 29 recover to deform at the moment, the first sealing plate 211 is reset, and the first sealing plate 211 seals the surface of the purging gas tank 28;
when the first connecting pipe 23 is used for flushing the filter element body 14, compressed air enters the piston housing 31 along the third connecting pipe 33, at the moment, the piston plate 310 in the piston housing 31 pushes the piston push rod 32 to move downwards, the connecting plate 36 is driven to move downwards under the pushing action of the piston push rod 32, and meanwhile, the second sealing plate 314 and the sealing ring 315 are driven to move downwards, so that the bottom of the fixed housing 11 and the first mounting plate 41 are opened;
when the piston plate 310 is pushed downward by the compressed air, the piston plate 310 blows out the air inside the piston housing 31 from the ends of the main air blowing pipe 38 and the branch air blowing pipe 39;
when the piston plate 310 moves downwards, the second spring 311 is compressed, and when one flushing is finished, the pressure release valve 34 discharges the compressed air in the piston housing 31;
the piston push rod 32 is driven to reset through the recovery deformation of the second spring 311, the fixing plate 35 and the connecting plate 36 are driven to reset, meanwhile, when the connecting plate 36 moves downwards, the connecting inner pipe 316 moves downwards along the connecting outer pipe 313, the third spring 319 is stretched, after the primary purging is finished, the third spring 319 also recovers deformation and drives the connecting inner pipe 316 to reset, so that the sealing ring 315 is driven to be in plugging sealing with the bottom of the fixed shell 11 again, dust is prevented from entering the fixed shell 11 from the bottom of the fixed shell 11, and when the connecting inner pipe 316 slides along the connecting outer pipe 313, the connecting inner pipe 316 is limited through the limiting plate 317;
when the filter element body 14 is damaged and replaced, the filter element body 14 is rotated by ninety degrees, the limiting insert 46 is located at the inserting opening position of the limiting insert plate 45, the filter element body 14 is pushed upwards under the action of the deformation recovery of the spring No. four 42, the filter element body 14 is convenient to take down, and meanwhile, when a new filter element body 14 is installed, the limiting insert 46 is inserted into the clamping opening position of the limiting insert plate 45, the mounting plate No. two 43 is pushed downwards by the bottom of the filter element body 14, the spring No. four 42 is compressed, the filter element body 14 is rotated by ninety degrees in the direction opposite to dismantling, and the limiting insert 46 is clamped inside the limiting insert plate 45, so that the filter element body 14 is convenient to install rapidly.
