Description

A dust collector for asphalt concrete mixing

technical field

The utility model belongs to the technical field of dedusting equipment, in particular to an asphalt concrete mixing dedusting machine.

Background technique

Asphalt concrete, commonly known as asphalt concrete, is artificially selected with a certain gradation composition of mineral materials, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials, mixed under strictly controlled conditions The resulting mixture and asphalt concrete are mixed through a mixing station. During the mixing of asphalt concrete, a large amount of dusty gas will be generated in the mixing station. These gases need to be dedusted by a dust collector before being discharged into the air. The bag filter will be used for dust removal, and the dust-containing gas will be introduced into the body through the fan on the bag filter. The filter bag inside the body of the bag filter is made of textile filter cloth or non-woven felt. The function is to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the action of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material , the dust is blocked and the gas is purified.

When the existing asphalt concrete mixing dust collector is in use, the air inlet of the fan will suck the dusty gas in the mixing station into the body for filtration, and the wind coming in from the air inlet will be discharged from the air outlet. In order to prevent external dust Entering the fan from the air outlet, a filter screen will be installed at the air outlet. However, when the mixer is not used for a long time, the dust collector is in a stopped state, and a lot of dust and impurities will fall on the surface of the filter screen in the fan. These dust and Impurities will adhere to the filter, which will easily cause blockage on the surface of the filter. When the dust collector is used again, the flow of air from the air outlet will decrease, which will cause the heat inside the fan to rise, causing the fan to overheat and burn out. Reduce the air intake at the air inlet on the fan, reduce the amount of dusty gas sucked into the body in the mixing station, and reduce the dust removal performance of the dust collector. For this reason, we propose an asphalt concrete mixing dust collector.
