Dust removal device and vacuum operation vehicle

Abstract

The invention relates to a dust removal device and a vacuum operation vehicle, wherein the dust removal device comprises: a box body (10) which comprises a first filtering chamber (A) and a second filtering chamber (B) communicated with the first filtering chamber (A); a settling structure (20) that is arranged in the first filtering chamber (A); a filter cylinder body (40) which is arranged in the second filter chamber (B); a combined cyclone dust removal structure (30) that is arranged in a communication channel between the first filter chamber (A) and the second filter chamber (B). The boxbody (10) is provided with an air inlet (11) and an air outlet (12), wherein the air inlet (11) is formed in the first filtering chamber (A), and the air outlet (12) is formed in the second filteringchamber (B). According to the embodiments of the invention, the requirement of filtering precision is met through integrated arrangement of multi-stage filtering, and the cleaning burden of the dust removal device is reduced.

Description

technical field [0001] The disclosure relates to a dust removal device and a vacuum operation vehicle. Background technique [0002] The vacuum suction vehicles in the related art mainly use vacuum suction and pneumatic conveying principles to suction and transport materials. After the airflow carries the material into the tank, most of the particles will settle, and the airflow carries a small part of the dusty gas along the air duct through the actuator and is discharged into the atmosphere. One of the actuators often used in vacuum suction vehicles is the Roots blower, which has higher requirements on the dust content of the gas. [0003] Considering that the dust with too high dust content or large particle size will damage the blades of the Roots blower and reduce the service life of the blower, a dust removal device is usually arranged between the tank and the Roots blower to minimize the wind resistance without significantly increasing the wind resistance. Reduce th...

AI Technical Summary

Problems solved by technology

[0004] The dust removal facilities used in workshops and construction equipment in the related art are relatively large in size and are not suitable for vehicle-mounted equipment. However, the dust removal devices of some vacuum suction vehicles in the related art use single or two single-stage cyclone centrifugal filters. The filtration accuracy of the filter is not high, generally the filtration accuracy of 20 μm or more does not exceed 80%, and because of the special requirements of the cyclone for the position of the air inlet and outlet and the wind speed, it is difficult to arrange the pipeline when the air volume is large, and the space required is large

Other dust removal devices for vacuum suction vehicles in the related art use cloth bags or filter cartridges to filter. Although this filtering method has high filtration accuracy, when the suction airflow has a high dust content and the gas humidity is high, the filter cartridges will Easy to clog, difficult to clean
