Description

Technical Field

[0001] The utility model relates to the technical field of crushing and dust removal devices, in particular to an inorganic non-metallic ore crushing and dust removal device. Background Art

[0002] Non-metallic minerals (calcite, talc, barite, hydromagnesite, wollastonite, etc.) are subjected to physical and mechanical grinding. Before entering the grinding equipment, they will undergo primary and secondary rough grinding (i.e., crushing process), and crush a weight of more than ten kilograms into small particles of about tens of grams. A large amount of dust is often generated during the crushing process. Although the surface dirt of the ore will be cleaned before crushing, and the remaining water will dilute some of the dust, a large amount of dust will still be generated due to the strong crushing force. Due to environmental protection issues, crushing cannot be done outdoors now. It is necessary to build a factory building and operate indoors, which makes it more difficult for dust to disperse and the workers will suffer physical harm. In order to reduce the dispersion of dust and reduce harm to the human body, an inorganic non-metallic mineral crushing dust removal device is specially developed. The crushing dust removal device consists of a dust inlet pipe, a box, an ash hopper, a clean air chamber, a high-pressure air pump, a blow pipe, a flower plate, a cloth bag, an air outlet pipe, a fan and an exhaust pipe. When the non-metallic ore is crushed, the dust generated by the crusher is connected to the dust inlet pipe through an external pipe, so that the dust generated by the crusher enters the box through the dust inlet pipe, the larger particles of dust fall into the ash hopper, and the smaller particles are filtered through the cloth bags on the flower plate and enter the clean air chamber. The fan is started, so that the gas in the clean air chamber is transported from the air outlet pipe to the exhaust pipe and finally discharged into the atmosphere. When cleaning the cloth bag, start the high-pressure air pump so that the generated gas is blown out from the holes on the blow pipe, thereby cleaning the cloth bag.

[0003] The inventor discovered in his daily work that when the crushing dust removal device is in use, the gas generated by the high-pressure air pump is blown out from the holes on the blow pipe, so that the blown gas is only in the vertical downward direction, resulting in poor dust cleaning effect on the side walls of the bag, thereby affecting the efficiency of the bag in filtering dust. Summary of the invention
