Pavement cleaning vehicle and dust and garbage separation and filtration device thereof

Abstract

The invention discloses a dust and garbage separation and filtration device and a pavement cleaning vehicle thereof. The dust and garbage separation and filtration device comprises a fan, a motor chamber, an air guide plate, a filtration grating, a settling opening and a screen, wherein the fan is mounted at the bottom of the motor chamber (402); after the fan is started, negative pressure is formed in the motor chamber; dust and garbage are sucked and then enter a garbage storage box through a corrugated pipe; the screen is arranged between the garbage storage box and the motor chamber for separating garbage; dust particles enter the motor chamber from the garbage storage box under the action of wind; the air guide plate is mounted at the outlet of the motor chamber; the air guide plate is used for reducing the air speed and the air pressure, so that dust can automatically settle down after being filtered and stacked by the filtration grating and enter a dust collection box through the settling opening. The dust and garbage separation and filtration device can automatically separate dust from garbage and collect the dust particles with the diameters greater than 1 micron into the vehicle-mounted dust collection box, so that road cleaning operation without flying dust can be realized.

Description

technical field [0001] The invention relates to a ground cleaning vehicle, in particular to a miniature electric self-priming cleaning vehicle. Background technique [0002] At present, there are many types of sanitation cleaning vehicles used for road cleaning, including large fuel-based road cleaning vehicles and small road cleaning vehicles. The common problems of large-scale fuel-based road cleaning vehicles are: poor economy, high emissions, and do not meet the increasingly stringent environmental protection requirements; excessive volume leads to dead spots in the road cleaning process, and the side and side corners of the road cannot be cleaned; There will be dust during the process of dumping and garbage, which will cause secondary pollution. Some large-scale cleaning vehicles reduce dust by spraying water while cleaning, but the effect is limited and it will cause roads to freeze in winter, which will bring hidden dangers to traffic safety.

Problems solved by technology

The common problems of large-scale fuel-based road cleaning vehicles are: poor economy, high emissions, and do not meet the increasingly stringent environmental protection requirements; excessive volume leads to dead spots in the road cleaning process, and the side and side corners of the road cannot be cleaned; There will be dust in the process of dumping and garbage, which will bring secondary pollution. Some large-scale cleaning vehicles reduce dust by sprinkling water while cleaning, but the effect is limited and the road will freeze in winter, which will bring hidden dangers to traffic safety.

[0003] The Chinese patent CN102465501 discloses a small-sized floor sweeper, which solves the problems of secondary dust raising, rapid bristle wear, The problem that the trash can is not cleaned at one time

However, its filter structure is a single-layer filter, which cannot effectively separate dust and other pollutants; at the same time, the device cannot effectively clean the corners of the road
