when the air compressor 8 works, the contact switch 5 is in a closed state, and the controller controls the first electromagnetic valve 61 to be in a normally open state and the second electromagnetic valve 62 to be in a normally closed state.
The air is sucked from the air inlet 31 of the three-way pipe 3, the one-way air valve I311 is pushed by the air to open inwards, the one-way air valve II 321 is kept closed, then when the upward air flow passes through the filter screen 20, dust is filtered and intercepted, the air flow continues to be upward, the fan blade 41 is pushed to rotate forwards when encountering the fan blade 41, the fan blade 41 drives the rotating shaft 40 to rotate forwards, and the one-way bearing II is in an unlocked state, namely, the first triangular brush 42 and the rotating shaft 40 and the second triangular brush 43 and the driven shaft 71 are both in rotary connection, so that the first triangular brush 42 and the second triangular brush 43 cannot rotate along with the rotating shaft 40.
The driven shaft 71 is driven by the rotating shaft 40 to rotate positively, and the section of the bottom of the rotating shaft 40 is of a spline structure with a non-circular section, so that the rotating shaft can slide in the driven shaft 71 and transmit torque. At this time, the first one-way bearing 73 is in a locked state, the driven shaft 71 rotates to drive the rotating ring 74 to rotate, so that the sliding shaft 72 in the sleeve 75 generates an outward centrifugal force, the sliding shaft 72 slides outwards, the sliding block 721 compresses the second spring 76, the brush 722 contacts the friction ring 77, the brush 722 keeps a fixed direction to rub against the friction ring 77 along with the rotation of the rotating ring 74, static electricity is generated on the friction ring 77, and when air with dust passes through the inside of the friction ring 77, the dust is adsorbed onto the friction ring 77.
When more dust is accumulated on the filter screen 20, the original air can pass through the filter screen 20, but after the filter screen 20 is blocked, the filter tube 2 at this time is equivalent to a piston, and the negative pressure above the filter tube 2 can suck the filter tube 2 for a certain distance, so that the sliding column 211 contacts with the contact switch 5, and the contact switch 5 triggers to be conducted.
The controller receives the conducting signal to control the first solenoid valve 61 to be closed and simultaneously opens the second solenoid valve 62, high-pressure gas stored in the gas tank in the air compressor 8 enters from the top of the outer pipe 1 to form downward air flow, the air flow contacts with the fan blades 41 to drive the fan blades 41 to rotate reversely, the first triangular brush 42 and the second triangular brush 43 are driven to rotate, so that the filter screen 20 is cleaned, and the cleaned dust is blown to the three-way pipe 3 in cooperation with the reverse air flow.
At this time, the first one-way air valve 311 is closed, the second one-way air valve 321 is opened, the air with dust passes through the friction ring 77, and the first one-way bearing 73 is in an unlocked state, and although the driven shaft 71 rotates, the rotating ring 74 stops rotating, the brush 722 is not contacted with the friction ring 77, static electricity is gradually weakened and reduced, dust adsorbed on the friction ring 77 can fall down, and the cleaned dust is collected and treated along with the first air flow blown from the discharge port 32 to the dust collecting yarn bag 322, so that the dust is prevented from overflowing.
It will be appreciated by those skilled in the art that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
