Dust-unloading vacuum dust control device of sweeper truck

Abstract

The invention discloses a dust-unloading vacuum dust control device of a sweeper truck. The dust-unloading vacuum dust control device comprises a hydraulic power system, a draught fan and a traveling dust sucking opening facing the ground. The device further comprises a dust staying box. The traveling dust sucking opening is communicated with the lower portion of the dust staying box through a pipe. The upper portion of the dust staying box is communicated with an air outlet pipe, and the draught fan driven by the hydraulic power system is installed in the air outlet pipe. A back box cover is arranged at a tail box body of the dust staying box, a dust-unloading dust sucking pipe extends from the portion, above the back box cover, of the tail box body, and an outlet of the dust-unloading dust sucking pipe is communicated with the dust staying box. According to the dust-unloading vacuum dust control device, after a back cover box of the dust staying box is opened and internal solid particles are unloaded, dust can be brought out, dust flying is also caused when solid particles fall on the ground, the dust-unloading dust sucking pipe is arranged at the back box cover and can re-suck the flying dust back into the dust staying box through the power supplied by the hydraulic power system, secondary dust flying is effectively avoided, the operation dust unloading environment is improved, and the dust control effect is good; the structure is simple and compact, energy consumption is low, and reliability is quite high.

Description

technical field [0001] The invention relates to the technical field of road sweeping equipment, in particular to a dust unloading vacuum dust control device for a road sweeper. Background technique [0002] Road sweepers are the main means for municipal departments to clean the city and beautify the environment. The number of vehicles in our country has reached 13,000, and their number is on the rise with the process of urbanization. However, when the sweeper unloads ash, it raises a large amount of dust particles, which endangers the health of workers. At present, most road sweepers mainly adopt the method of dust suppression with fog curtains. The water stored in the vehicle body is sprayed into water mist through the water pump, and the dust is captured to make it settle naturally. However, this method has a dust control blind area, and the dust removal efficiency is not high; at the same time, the introduction of water channels leads to a complex internal structure of t...

Problems solved by technology

However, this method has a dust control blind area, and the dust removal efficiency is not high; at the same time, the introduction of water channels leads to a complex internal structure of the road sweeper, high energy consumption, and waste of water resources; and the dust settled on the ground after humidification is not easy to clean
