Description

A dedusting device for empty cement packaging bags

technical field

The utility model relates to the technical field of cement packaging bag processing, in particular to a dedusting device for empty cement packaging bags.

Background technique

Before the assembly of cement packaging bags, it is usually necessary to dedust the bagged cement. Most of the existing cement packaging bag dust removal devices use the principle of wind blowing for dust removal. The dust on the cement bag is blown up by the corresponding air blowing structure, and the raised dust is then absorbed by the preset dust suction structure. Since the cement bag is always lying flat on the conveyor belt, the dust below or on both sides of the cement bag is less affected by the wind force of the upper blowing structure, and some dust cannot be removed after sticking to the bag body in a short time, requiring a longer conveyor belt To achieve long-term blowing, the existing dust removal device has the characteristics of incomplete dust removal and low efficiency. In addition, if the dust removal effect is to be increased, the output wind force of the blower or suction fan needs to be increased, and it is necessary to increase the blower or suction fan. It consumes more energy and increases the production and operation cost of the enterprise.
