The cleaning mode can be selected automatically in three modes of automatic, manual and manual remote control; because only one strip-shaped range of the filter element is subjected to pulse back flushing during back flushing, and the area of one side of the strip-shaped nozzle 15, which is opposite to the plate-type filtering filter element 18, namely the cleaning area is smaller than 1/25 of the ventilation area of the plate-type filtering filter element 18, the normal operation of an engine is not influenced during self cleaning, and the cleaning can be performed under the normal operation condition of the engine, namely online cleaning is realized.
The specific use of the self-cleaning boxed vehicle air filter 100 of the present embodiment is as follows:
a vehicle power supply (12 or 24Vdc) is connected to the controller 2, and an air source (0.5-1.0 MP) is connected to the air inlet interface 13. When the filter element is clean or the air inlet pressure difference is smaller than the set value, the controller 2 is in a standby state and does not output signals, air containing impurities such as dust enters through the air inlet of the air inlet rain-shielding shutter cover plate 19, and after the air is filtered by the plate type filtering filter element 18, clean air enters the engine through the air outlet 4. When the differential pressure switch 5 measures that the differential pressure of the air purifying chamber reaches the set highest pressure, the dust holding capacity of the plate-type filtering filter element 18 is indicated to reach the allowable limit, the differential pressure switch 5 sends a contact signal, the controller 2 is started immediately, the driving device 3, namely a direct current motor, is started firstly, a screw rod of the reciprocating screw 8 is driven to rotate at the designed speed through a driving chain wheel 11, a chain 10 and a driven chain wheel 9, a nut, namely a sliding block of the reciprocating screw 8 drives the pulse blowing valve 7 and the strip-shaped nozzle 15 to move slowly in one direction, and it needs to be noted that a limiting element is arranged in the reciprocating screw 8 to prevent the nut, namely the sliding block of the reciprocating screw 8 from rotating along with the screw rod of the reciprocating screw 8, and the method belongs to the prior mature technology and is not described herein again; at the same time, the controller 2 sends a series of pulse signals with a certain period and a certain pulse width to the pulse blowing valve 7. Because the pulse injection valve 7 is connected with the energy accumulator 6 through the flexible hose, compressed air carries out pulse back flushing with time sequence from inside to outside to the plate-type filtering filter element 18 through the pulse injection valve 7 → the strip-shaped nozzle 15 by using compressed air, and accumulated dust washed out by the back flushing in the filter element freely falls to the dust discharge port 20 under the action of gravity and is discharged outside the box body; because the strip-shaped nozzle 15 only carries out back washing on the part of the plate-type filtering filter element 18 which is less than 1/25, the normal operation of an engine is not influenced when the filter element is washed, and the aim of back washing the filter element without stopping the engine is fulfilled. This backwash process will not stop as long as the inlet pressure difference is greater than the set minimum value. Because the strip-shaped nozzle 15 continuously moves towards one direction, all parts of the plate-type filtering filter element 18 can be continuously back-washed; when the strip-shaped nozzle 15 moves to the top end position of the plate-type filtering filter element 18, the nut, namely the sliding block, matched with the reciprocating lead screw 8 can drive the strip-shaped nozzle 15 to automatically return, so that the strip-shaped nozzle can reciprocate for a plurality of times, all parts of the plate-type filtering filter element 18 are repeatedly washed for a plurality of times, until the air inlet pressure difference reaches the minimum value of a set value, the differential pressure switch 5 sends a stop signal, the controller 2 sends a stop signal, the driving device 3, the energy accumulator 6 and the pulse blowing valve 7 are closed, and the cleaning process can be automatically stopped.
In the description of the present invention, it should be noted that the terms "top", "bottom", "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
