Particle material sieving machine

Abstract

The invention discloses a particle material sieving machine, comprising a rack; a spindle is arranged on the rack and is rotationally connected with an electric motor-driven sieve drum by a rotary cover and a support arm, wherein openings are formed in two ends of the sieve drum; the opening in the front end of the sieve drum is a charging opening; the opening in the rear end of the sieve drum is a discharging opening; the spindle and the sieve drum are obliquely downwards arranged from front to back; sieve meshes are formed in the drum wall of the sieve drum; the sieve drum is divided into a fine sieve section, a middle sieve section and a thick sieve section from front to back; the sieve meshes in the fine sieve section are smaller than those in the middle sieve section; the sieve meshes in the thick sieve section are larger than those in the middle sieve section; three material outlets arranged by respectively corresponding to the fine sieve section, the middle sieve section and the thick sieve section are formed in the bottom of a material box; the spindle is provided with a cleaning arm extending to the inner wall of the sieve drum. The cleaning arm is provided with a cleaning head capable of cleaning the sieve meshes. The particle material sieving machine has the advantages of high sieving efficiency and good sieving effect.

Description

technical field

[0001] The invention belongs to chemical fertilizer manufacturing equipment, in particular to a granular material screening machine. Background technique

[0002] Existing compound chemical fertilizers are formulated from various materials. The production process is to stir and mix various substances containing nitrogen, phosphorus, and potassium, then granulate them through a granulator, then dry or dry them in the air, and finally use a screening machine to screen out compound fertilizer particles of appropriate size. . In the screening process of granular materials, the existing screening machine is a vibrating screening machine, which includes a frame with two sieve plates arranged horizontally from top to bottom on the top of the frame, and the two sieve plates are respectively driven by a vibration motor. The sieve hole is set on the sieve plate, and the sieve hole on the upper sieve plate is larger than the sieve hole on the lower sieve plate. When u...
