Dust collection device for highway construction

Abstract

The invention relates to a dust collection device for highway construction. According to the technical scheme, the device comprises a casing provided with a horizontal channel, wherein a filter cartridge, a semi-ring filtering net and rotary scraper plates are arranged in the channel, axes of the filter cartridge, the semi-ring filtering net and the rotary scraper plates are vertical and coaxiallyarranged, the semi-ring filtering net is arranged on the inner side of the filter cartridge, the rotary scraper plates are arranged on the inner side of the semi-ring filtering net and make contact with the inner side surface of the semi-ring filtering net; a planetary gear mechanism coaxial with the filter cartridge is arranged on the casing, a sun gear of the planetary gear mechanism is coaxially connected with the rotary scraper plates, a planet carrier of the planetary gear mechanism is fixed on the casing and coaxially connected with the semi-ring filtering net, a gear ring of the planetary gear mechanism is coaxially connected with the filter cartridge, and the planetary gear mechanism is driven by a driving device; an ash collecting hopper below the casing is arranged on the casing, a partition board is arranged on the inner side of the ash collecting hopper and divides the ash collecting hopper into a left chamber and a right chamber, and the left chamber and the right chamberare communicated with the channel on the left side of the filter cartridge and the inner side of the semi-ring filter net respectively. The device also comprises a water spray purification system.

Description

technical field [0001] The invention relates to a highway construction device, in particular to a highway construction dust removal device. Background technique [0002] In the process of expressway construction, especially during the excavation, cleaning and leveling of the road surface, as well as the transportation and loading and unloading of aggregates, concrete mixing and mixing, etc., a large amount of smoke and dust pollution will inevitably be generated. This kind of smoke and dust is mostly composed of dust, cement Composed of sand and gravel, etc., it has strong hydrophilicity, and this kind of pollution is usually difficult to deal with because it occurs in open areas; generally, for this kind of outdoor pollution, spraying and sedimentation devices are often used for treatment, but this kind of spraying device It consumes a lot of water resources. After the water mist settles and falls on the ground, it cannot be recycled on site. It is obviously difficult to en...
