The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of cascade machine with the dust scavenge unit; Mainly form by air intake and exhaust system 1, dust filtering device 2, filtering trough 3, drainpipe 4, cistern 5, water circulating pump 6, flow pipe 7, air cleaning unit 8; Described dust filtering device 2 is placed in the top of filtering trough 3; Comprise roll shaft 21, lower roller shaft 22, power set 23, be enclosed within the filter screen 24 on roll shaft and the lower roller shaft, and the dust scavenge unit 25 that is arranged in filtering trough 3, described dust scavenge unit 25 is made up of the axle of the parallel band hairbrush of more than one and lower roller shaft 22; The hairbrush on described dust scavenge unit 25 surfaces closely contacts with the filter screen 24 on the lower roller shaft 22; Power set 23 further drive filter screen 24 when driving lower roller shaft 22 rotations and rotate, and filter screen 24 rotates drive dust scavenge unit 25 and rotates, and the hairbrush on dust scavenge unit 25 surfaces are cleaned the dust on filter screen 24 surfaces in the water with water.
Described dust scavenge unit 25 is made up of the axle of the parallel band hairbrush of more than one and lower roller shaft 22; Embodiment as shown in fig. 1 is made up of the axle of three band hairbrush; The axle of these three band hairbrush all closely contacts with filter screen 24 respectively; Like this, will drive dust scavenge unit 25 during the filter screen transhipment and rotate, thereby hairbrush can be cleaned the dust on the filter screen 24 in the water with water.
The output gear 231 of power set 23 and the power input gear interlock of lower roller shaft 22 drive lower roller shaft 22 and rotate.
The frictional force that 25 of described dust scavenge units produce when needing to rely on filter screen 24 transhipments just can be rotated; Travelling gear 221 can also be set on lower roller shaft 22; Through power input gear 251 interlocks of travelling gear 221, realize that lower roller shaft 22 drives dust scavenge unit 25 and rotates when rotating with dust scavenge unit 25.
Described filtering trough 3 is communicated with cistern 5 through drainpipe 4, and the water that cistern is 5 li pumps into flow pipe 7 through water circulating pump 6, sprays on roll shaft 21 and the filter screen 24.Cistern 5 is used to precipitate dust, and supplies water for water circulating pump 6.Mix dust gets into the cisterns 5 through drainpipe 4 from filtering trough 3 in water, and through after a while, dust sinks to cistern 5 bottoms in the gravity effect, regularly discharges through the water channel that is located at the bottom of the pond again.
At the rear of air intake and exhaust system 1 air purifying room 8 is set.
Be mounted with air purifier 81 in the described air purifying room 8, on wall, be provided with exhaust outlet 82.
During work, power set 23 drive goes up roll shaft 21 and lower roller shaft 22 rotations, and then drive filter screen 24 rotates; Dust is attracted on the filter screen 24 by air intake and exhaust system 1, and most dust adheres on the moist filter screen 24, is driven by filter screen 24 to move down; When filter screen 24 process dust scavenge units 25,, form bigger frictional force between the two because both closely contact; Dust scavenge unit 25 also can rotate under the drive of filter screen 24, and the hairbrush on dust scavenge unit 25 surfaces brushes the dust on the filter screen 24 in the water, passes through water logging once more through the filter screen 24 that cleaned; Under the effect of power set 23, move from a side direction near air intake and exhaust system 1, a small amount of dust that sees through the front filter screen further adheres on the filter screen 24; Filter screen continues to move up, turn over roll shaft 21 after, be moved down in the filtering trough 3 after adhering to a large amount of dusts again; Soaked by removing dust of the hairbrush on the dust scavenge unit 25 and quilt once more, under the effect of power set 23, moved up again, so moved in circles; Constantly air flowing is purified, with airborne dust adhesion and take in the water, make the air that gets into air blast only contain a spot of dust and pernicious gas.
The air that air blast will contain low amounts of dust and pernicious gas blows into air purifying room 8, and airborne pernicious gas after air purifier 81 purifications, is discharged through exhaust outlet 82 again.
