Screening device used for compound fertilizer production

Abstract

The invention provides a screening device used for compound fertilizer production. A fine material collecting tank and a coarse material collecting tank are arranged at the top end of a bracket in parallel. The top end of the fine material collecting tank is provided with a screening cover. An obliquely-arranged screening net is arranged at the top end of the fine material collecting tank, and the screening cover covers the screening net. The bottom end of the screening net extends into the coarse material collecting tank. The top end of the screening cover is provided with a material inlet. The material inlet is in sealing connection with an outlet of a feeding auger. One side of the fine material collecting tank is provided with a fine material discharging pipeline. The end of the fine material discharging pipeline is provided with a thread dustproof cover. The bottom end of the coarse material collecting tank is provided with a coarse material outlet. An air inlet of a spiral dust remover is connected to the top end of the coarse material collecting tank through a pipeline. An air outlet of the spiral dust remover is connected with an air exhaust mechanism. The bottom end of the spiral dust remover is provided with a dust collecting box. The screening device used for compound fertilizer production has the beneficial effects of being good in screening effect, dustproof and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production equipment, and in particular relates to a screening device for compound fertilizer production. Background technique [0002] Most of the existing screening equipment for compound fertilizer materials lack a certain dust-proof system, and a large amount of dust overflows during the screening process, which not only pollutes the working environment, but also seriously affects the health of the staff. There is also a small amount of fine material mixed in the material, which is easy to cause waste of resources. A screening device for compound fertilizer production that can solve these problems needs further research and development. Contents of the invention [0003] The purpose of the present invention is to provide a screening device for compound fertilizer production with simple structure, simple operation and good dust-proof effect. [0004] The technical solution of the...
