Description

A concrete mixing dust removal device

technical field

The utility model relates to the field of dust removal devices, in particular to a concrete mixing dust removal device.

Background technique

Concrete is a general term for engineering composite materials that cement aggregates into a whole by cementitious materials. Its raw materials generally include cement, sand, fly ash, additives, and water. In the concrete production process, the concrete raw materials are generally added into the mixing device, and the concrete raw materials are mixed evenly to obtain the concrete. The existing concrete mixing plant, in the mixing process, dust will inevitably scatter, and the dust will cause environmental damage Certain pollution, the dust will enter the breathing pipe of the staff, and then affect the health of the staff, which is very harmful. The traditional dust removal device adopts bag dust removal, but the dust particle size of the concrete mixing plant is small, and the dust after the filter element is used for a long time Too much adsorption will lead to blockage of the filter element, which will reduce the filtering capacity of the dust removal device. Therefore, workers need to pull out the filter element of the dust removal device regularly, clean the filter element or replace the filter element, which will reduce the service life of the dust removal device and affect production. Efficiency, and the operation is also very inconvenient, so we propose a concrete mixing dust removal device.
