Technical Field

[0001] The utility model relates to the field of machine-made sand production, in particular to an induced draft dust removal device for a machine-made sand production line for pavement. Background Art

[0002] Sand making refers to the process of crushing and screening natural rocks, pebbles, or mine tailings and other raw materials through mechanical equipment to produce sand particles. Compared with natural river sand, machine-made sand has a more uniform particle size distribution and higher strength, and is widely used in construction projects such as buildings, roads, and bridges.

[0003] The induced draft dust removal device of the existing machine-made sand production line for pavement is usually installed near the machine-made sand discharge port, and then the induced draft fan draws air into the dust collection barrel through the pipe, and the dust is filtered through the filter. However, since there is a lot of dust sticking to the filter, it is easy to cause blockage, and the high-speed flow of air in the pipe and the dust collection barrel will generate friction, which in turn generates heat. The high temperature will accelerate the aging of the filter bag material, resulting in a decrease in the strength of the filter bag, thereby affecting the service life of the filter bag.

[0004] Therefore, it is necessary to design an induced draft dust removal device for the road surface machine-made sand production line that can knock the filter bags during the dust removal process, cool the filter bags, reduce the blockage of the filter bags, and extend the service life of the filter bags. Utility Model Content
