the gas after rough filtration enters a filter element cabin of the air purification device through an air outlet of the cyclone dust collector, the gas is filtered in the filter element cabin through a dust removal filter element, and the filtered gas is discharged to the outside of the vehicle body through an air outlet of the fan through an air outlet channel.
3. The system of claim 2, further comprising a blowing device disposed outside the cartridge compartment at a position corresponding to the filter cartridge, the blowing device blowing dust attached to the dust removing filter cartridge in a reverse direction.
4. The system of claim 1, wherein the suction ports comprise a first suction port and a second suction port, the suction ports respectively face the spark discharge direction of the respective polishing head, and the suction ports are deflected and laterally moved together with the respective polishing head while being independently movable up and down.
5. The system of claim 4, wherein the air intake duct comprises a first air intake duct and a second air intake duct, a lower end of the first air intake duct communicates with an outlet end of the first dust suction port, and a lower end of the second air intake duct communicates with an outlet end of the second dust suction port.
6. The system of claim 5, wherein the cyclone comprises a first inlet port and a second inlet port, the first inlet port communicating with an upper end of the first inlet pipe, the second inlet port communicating with an upper end of the second inlet pipe, each inlet port being provided with a solenoid valve capable of controlling whether the inlet pipe communicates with the cyclone.
7. The system of claim 1, wherein the cyclone comprises an outer tub and a core tub disposed inside the outer tub, and the lower portion of the outer tub is first formed in an inverted cone shape having a cross-sectional area gradually decreasing downward, and then formed in a cylindrical shape having a cross-sectional area unchanged and inserted into the total dust box.
8. The system of claim 7, wherein a cambered baffle is arranged below the hole of the main dust collecting box communicated with the cyclone dust collector at a certain distance, and the convex surface of the cambered baffle is opposite to the cyclone dust collector so as to uniformly disperse the falling dust in the drawer.
9. The system as claimed in claim 2, wherein level sensors for monitoring the dust accumulation height are arranged in the main dust collecting box and the filter element dust collecting box, the level sensors are electrically connected with the main controller, and when dust in the main dust collecting box and the filter element dust collecting box reaches a preset position, the level sensors send signals to the main controller.
10. The system of claim 1, wherein a fireproof chain and a fireproof valve are arranged in the air inlet pipe, the fireproof chain and the fireproof valve are provided with a temperature sensor, the temperature sensor is in circuit connection with the main controller, when the temperature of the air sucked in the air inlet pipe is higher than a set value, the temperature sensor sends a signal to the main controller, the main controller cuts off the power supply of the fan, pulse blowing is stopped, and the fireproof valve is closed.
