Wherein, the first telescopic cylinder 25 is connected with the dust removing unit 3, the second telescopic cylinder 46 is connected with the rigid plate 411, and the third telescopic cylinder 44 is connected with the hose 43 through springs.
The specific working process is as follows:
when the dust removal device works, the exhaust fan 15 extracts gas in the dust removal box 1 through the gas outlet pipe 12 to enable negative pressure to be generated in the dust removal box 1, the gas inlet pipe 11 extracts gas with dust in the external environment under the action of the negative pressure in the dust removal box 1, the gas with the dust enters the gas inlet pipe 11, the end part of the gas inlet pipe 11 is over against the dust removal plate 2, the gas entering the gas inlet pipe 11 directly impacts the dust removal plate 2 to cause the dust removal plate 2 to swing, the first filtering cloth 22 on the dust removal plate 2 filters the gas with the dust rushed out from the gas inlet pipe 11 for the first time, and the dust attached to the first filtering cloth 22 falls into the flexible conical funnel 41 under the swinging of the dust removal plate 2; meanwhile, the dust removing plate 2 swings to extrude the first air bag 23, and the gas in the first air bag 23 is compressed into the first telescopic cylinder 25 to enable the first telescopic cylinder 25 to intermittently extend and retract; the first telescopic cylinder 25 intermittently extends and retracts to push the dust removal unit 3 to shake back and forth, the adjacent dust removal units 3 swing along with the action of the first spring 31, so that the whole dust removal unit 3 is intermittently extruded by the first telescopic cylinder 25, the second air bag 32 is compressed, the surface of the second filter cloth 34 outside the second air bag 32 is extruded and deformed, dust on the second filter cloth 34 falls off, gas is discharged sequentially through the second filter cloth 34, the air outlet pipe 12 and the exhaust fan 15, gas with pressure higher than that in the dust removal unit 3 is introduced into the blowing main pipe 13, and the dust removal unit 3 is intermittently blown from inside to outside under the action of the pulse valve 14, so that dust on the surface of the dust removal unit 3 is easy to fall; the falling dust falls into the dust collecting unit 4, at the moment, the air bag II 32 is intermittently compressed by the telescopic cylinder I25, the air in the air bag II 32 is compressed into the telescopic cylinder II 46, the telescopic cylinder II 46 intermittently pushes the flexible conical funnel 41 to make the flexible conical funnel 41 vibrate intermittently, and the dust on the flexible conical funnel 41 naturally falls into the collecting tank 51 through the hose 43; because water exists in the collecting tank 51, dust is not easy to raise, meanwhile, the spray nozzle 53 sprays water into the flexible conical funnel 41, dust attached to the flexible conical funnel 41 flows into the collecting tank 51 along with the water, the water in the collecting tank 51 is increased, the increased water in the collecting tank 51 enters the water tank 52 along the first water pipe, the gas in the air bag III 54 is compressed into the water tank 52, the water in the water tank 52 is extruded to the spray nozzle 53, so that the water circulates back and forth in the spray nozzle 53, the flexible conical funnel 41, the collecting tank 51 and the water tank 52, after more dust is accumulated in the collecting tank 51, the water in the collecting tank 51 is replaced once, and the dust in the collecting tank 51 is poured; meanwhile, water sprayed from the spray head 53 falls into the collecting groove 51, the water surface in the collecting groove 51 ripples, the floating plate 451 moves up and down along with the ripples on the water surface, the floating plate 451 moving up and down enables the four 45 telescopic cylinders to generate compressed gas, the gas in the four 45 telescopic cylinders is delivered to the three 44 telescopic cylinders, and the three 44 telescopic cylinders intermittently extend and retract to enable the hose 43 to shake, so that dust is not easy to condense on the inner wall of the hose 43.
(A) In the above embodiment, the suction fan generates negative pressure in the dust removing box, so that the air inlet pipe extracts air with dust in the environment, but the invention is not limited thereto, and a negative pressure machine can be directly added at the air inlet pipe to make the suction pipe extract air with dust in the environment.
Industrial applicability
According to the invention, negative pressure is generated in the dust removal box through the exhaust fan, dust is filtered twice through the dust removal plate and the dust removal unit, the dust removal and filtration effects are good, the dust is collected and integrated into the water circulation unit through the dust collection unit, the dust removal plate and the dust collection unit continuously vibrate in the whole collection process, the dust blockage is avoided, and the improvement of the dust removal efficiency of the cloth bag industrial dust collector is realized; therefore, the cloth bag industrial dust collector is useful in the technical field of industrial dust collection.
