The working principle of the utility model is as follows:
1) when the vehicle is cleaned, the state of the filtering device is as shown in fig. 2, at the moment, the air inlet opening and closing push rod 20 is in a stretching state to enable the air inlet opening and closing valve 18 to be closed, the sealing plate opening and closing push rod 11 is also in a stretching state to enable the sealing plate 8 to be opened, the air inlet flange 201 is connected with the pneumatic conveying air duct, the filtering cavity 2 is communicated with the suction nozzle, and the garbage can sealing ring 1 is attached to the garbage can to form a closed space. The flowing direction of the gas is shown as the arrow in the figure, the gas mixed with the pollutants enters the filter cavity 2 through the air inlet A, the pollutants are separated and deposited from the gas in the dustbin due to the gravity sedimentation and the filtering action of the coarse filter screen 4, the turbid gas is purified by the filter element 6 and then is discharged from the air outlet B, and the dust is gathered on the inner surface of the filter screen of the filter element 6.
2) When the vehicle is used for cleaning, if the filter element 6 is blocked to influence the suction force, the vibration motor 12 can be started to carry out mechanical vibration ash removal under the condition of not closing the pneumatic conveying system, and most of dust collected on the inner surface of the filter screen of the filter element 6 is removed.
3) After the vehicle finishes cleaning operation, in order to avoid the increase of air exhaust resistance caused by dust deposition on the surface of the filter element 6, the operation effect is influenced, and the operation energy consumption is increased. At this time, the filtering device is adjusted to the state shown in fig. 3 (i.e. the air inlet opening and closing push rod 20 is contracted to open the air inlet opening and closing valve 18, the sealing plate opening and closing push rod 11 is contracted to push the guide ring rotating handle 13 to rotate, so that the sealing plate 8 is closed, a closed body is formed on the surface of the filter element 6, the suction nozzle is retracted to be away from the ground, the garbage can is separated from the garbage can sealing ring 1, then the vibration motor 12 is started, and simultaneously the centrifugal fan of the pneumatic conveying system is started to provide a back blowing air source, the flow direction of the air is shown by the arrow in fig. 3, because the clean air passes through the air inlet A and is blocked by the air inlet opening and closing valve 18, the clean air can only enter the air inlet ring 7 through the air inlet 202, because of the closed body surrounded by the closed sealing plate, the air is diffused to the surface of the filter element 6 and flows to the interior of the filter element 6 from the outer surface of the filter element 6, and the dust attached to the inner surface of the filter element is cleaned under the action of the back blowing air flow, and is discharged through the bottom of the filter cavity 2, thereby realizing deep cleaning of the filter element 6.
4) The action of the compression spring 17 mainly comprises two aspects: firstly, unnecessary damage or looseness caused by the high-frequency vibration of the vibration motor 12 transmitted to other parts due to rigid connection is avoided, and the effect of isolating a vibration source is achieved; secondly, if the dust removal of the filter element 6 is carried out under the rigid connection condition, the vibration motor 12 needs larger exciting force, and the length of the guide stud 15 is adjusted, so that the compression spring 17 generates compression deformation to obtain proper elastic potential energy, the filter element 6 obtains proper supporting rigidity, the exciting force needed by the vibration motor 12 can be effectively reduced, and the better dust removal effect of the filter element 6 is achieved.
5) And a back-blowing air source of the filtering device is provided by a centrifugal fan of the pneumatic conveying system, and the air circuit is switched by opening and closing the valve 18 through the air induction port, so that the back-blowing ash removal function of the filter element 6 is realized.
