Abstract

The invention relates to a packaging dust removal method for a feed inlet. The packaging dust removal method mainly solves the problems of easy dust generation and poor dust gathering effect of the feed inlet in the prior art. The packaging dust removal method provided by the invention adopts a packaging dust removal device for dust removal work, wherein the packaging dust removal device comprisesa feed cabin feeding pipe, a dust removal cover, a dust removal air pipe, a cloth bag dust remover, an air blower, a bag clamping device, an automatic lift-drop device and a baffle plate. Thus, the above-mentioned problems are well solved, and the packaging dust removal method can be used for packaging dust removal for the feed inlet.

Description

technical field [0001] The invention relates to a packaging dust removal method at a feeding port. Background technique [0002] The bottom of the silo of many industrial production devices is provided with a discharge port, and the product is packaged manually. In the packaging process of powder materials, due to the large material drop and fast falling speed, a large induced wind will be generated. If the particle size of the packaging material is small, it is very easy to generate dust [Ye Hong, Men Xiaotang, Guan Jingping, etc. A large chemical fertilizer company Analysis of Occupational Hazards and Critical Control Points in Urea Packaging, Storage and Transportation System [J]. Chinese Journal of Industrial Medicine, 2014, 27(2), 138-140.]. In order to control the dust hazard during the blanking packaging process, the existing packaging dust removal device usually uses a packaging bag to be fixed on the feeding pipe through a clamping device, and a dust collection hoo...
