Description

Complete pneumatic dry-type dust-proof vehicle

Technical field: the utility model relates to a kind of whole employing air-flow and finishes cleaning work, without brush, and the complete pneumatic dry-type dust-proof vehicle of not spraying water.This vacuum sweeper especially can effectively solve the reentrainment of dust in the clear operation, and can effectively save the resource that expends in the cleaning work.

Background technology: well-known, present sweeper both domestic and external all be unable to do without " a sweeping " word, all is to adopt brush to roll to clean.Dish brush with circle is swept to the centre with ground rubbish, with blower fan rubbish is sucked ash bin then.Spray water in ash bin, by gravitational settling, water smoke presses the way of dirt that the bulky grain thing is precipitated.Trickle dust enters atmosphere by blower fan, and some trickle dust waft along with the discharge of gas again to aerial, have brought the reentrainment of dust pollution.In the process that brush is swept the floor,, continually again spray water earthward with on the brush in order to have prevented ash, the result is not a dust and become mud, has adhered to exactly on the ground, waits water one to do, dust is again to wave everywhere in the same old way, and on the ground dust in the ditch seam be sweep forever sordid.Therefore existing sweeper can't be removed ground fine dust effectively.Owing to will spray water, not only wasted water resource, north of china in winter freezes and is difficult for cleaning work, but also has brush heavy wear, often change defectives such as brush, maintaining difficulty, usage charges height.

Summary of the invention: in cleaning work, adopt brush and water spray and waste resource in order to solve existing sweeper; the water spray north of china in winter freezes and is difficult for cleaning work; in the cleaning work process; the rubbish thing deposits ash bin in; fine solid particle produces the deficiency that reentrainment of dust pollutes along with gas enters atmosphere; the utility model provides a kind of complete pneumatic dry-type dust-proof vehicle; this vacuum sweeper not only in the cleaning work process without brush; do not spray water; saved resource; the air-flow that all adopts the blower fan running to produce; pressure-vaccum is in conjunction with the ground refuse thing is collected; and in the closed-loop path of an air, produce separating of gas and rubbish thing; rubbish thing after the separation exists in the ash bin, and the gas after the separation blows the ground refuse thing again and enters ash bin by air intake duct, moves back and forth like this; gas is not excessive; pollute thereby solved the reentrainment of dust in the cleaning work, reduced the content of pellet in the atmosphere, protected atmospheric environment effectively.

The technical scheme that its technical problem that solves the utility model adopts is: complete pneumatic dry-type dust-proof vehicle comprises a walking car body, loads a dust exhaust apparatus on the car body, and its structure is to drive draught fan impeller by engine to rotate at a high speed.Certain vacuum is pumped into by ash bin lower floor, air intake duct picks up dust rubbish and enters ash bin lower floor, at this point unexpected diffusion, air velocity is slack-off, and the material that most of quality is bigger all gets off by gravitational settling, and the realization air first time separates with dust, and some fine solid particles are sucked by draught fan impeller, under the rotation of impeller high speed, in impeller, obtain energy and got rid of air intake machine casing with certain speed and pressure, dust is done the high speed circular motion in fan casing.According to the centrifugal force formula: F=m ω v (centrifugal force=quality * angular speed * linear velocity) shows: under identical speed, quality is big more, the centrifugal force that obtains is big more, because the quality of dust is far longer than the quality of air, so more close fan casing border movement of dust, thereby dust has produced with gas and has separated, and the realization air second time separates with dust.Gas after the separation is subjected to the effect of inertia force to be got rid of into the position, upper strata of ash bin and precipitate, and the gas after separated is in guide ring after the supercharging, enter the dust suction dish along wireway, in the dust suction dish, enter each air nozzle, air-flow blows to central authorities from air nozzle ejection with the floor-dust foreign material and concentrates, and then is picked up by air intake duct and to enter ash bin.Because without brush, do not spray water, all adopt air-flow to carry out cleaning work; gas moves in a closed-loop path; gas is not excessive; thereby having solved the reentrainment of dust in the cleaning work pollutes; reduced the content of pellet in the atmosphere; protect atmospheric environment effectively, reached environmental protection, purpose of energy saving.
