Multistage dust removal dustbin for sweeper

Abstract

The invention discloses a multistage dust removal dustbin for a sweeper. A dust collection fan works to generate negative pressure in a lower chamber; garbage conveyed by a sweeper garbage conveying hanging plate enters the lower chamber from a garbage dust inlet; dust sucked by a dust suction air pipe of a sweeping disc of the sweeper enters the lower chamber through a dust suction pipe; dust particles with increased mass in the air flow are descended and settled to the bottom of a garbage can body under the action of gravity; and the other part of dust is filtered by a filter cloth bag, andthe filtered clean air enters an upper chamber and then is discharged through an air outlet, so that secondary dust pollution is avoided, and the problems that a pure sweeping type sweeper is large indust, short in water spraying endurance, free of effective dust falling measures in winter construction, excessive in discharged atmosphere and polluting the environment are solved.

Description

technical field [0001] The invention relates to the technical field of sweepers, in particular to a multi-stage dust-removing garbage box for sweepers. Background technique [0002] The homogenization of existing domestic road sweeper products is relatively serious, and the main functions are designed for municipal road sweeping, which are mainly divided into pure sweeping and suction sweeping. The main problem of pure sweeping sweepers is that the water spraying effect is average, the water spraying volume is large, and the water tank is small, which cannot meet the long-term cleaning operation, and the construction in the cold winter season cannot be sprayed and dusted, causing secondary cleaning operations. Dust pollution will seriously affect the safe driving of vehicles behind; the main problem of suction-sweeping sweepers is that when the suction nozzle sucks the ground garbage into the garbage bin, huge wind speed and air volume are required, which wastes a lot of ene...

AI Technical Summary

Problems solved by technology

The main problem of the pure sweeping sweeper is that the effect of water spraying and dust reduction is average, the water spraying volume is large, and its own water tank is small, which cannot meet the cleaning operation for a long time. In addition, water spraying and dust reduction cannot be carried out during construction in the cold winter season, causing secondary pollution during the cleaning operation. Dust pollution will seriously affect the safe driving of the rear vehicles; the main problem of the suction-sweeping sweeper is that when the suction nozzle sucks the ground garbage into the garbage bin, it needs a huge wind speed and air volume, which wastes a lot of energy and will generate dust in the garbage bin. A large amount of dust, when the suction fan extracts the air from the dustbin, it will take out the dust in the dustbin and the garbage with relatively small quality, and discharge it into the atmosphere, resulting in secondary pollution. At the same time, the dust particles increase the loss of the fan. Reduced service life
