Disc screen

Abstract

The invention discloses a disc screen. The disc screen comprises a frame of a sealed box body structure. A feed port is formed in an upper sealing plate of the frame, multiple separation openings areformed in a lower sealing plate, and connecting seats are connected below two upper end beams of the frame. Each screening roller comprises a mandrel, wherein a regular hexagonal spindle section is arranged in the middle of the mandrel, the positioning section of the mandrel is rotationally connected to the lower surfaces of the connecting seats through mounted bearings, double rows of chain wheels are fixed to the transmission section of the mandrel, and the double rows of chain wheels are in transmission through a single-row chain. Another transmission section of the mandrel on the outermostside is connected with a reduction motor through a coupler, multiple regular hexagonal discs are arranged at equal intervals and distributed on the spindle sections by periodically spirally rotatingat certain angles, and the discs of the former screening roller are located in the gap between every two adjacent discs in the later screening roller. The disc screen has the effects that the regularhexagonal discs are long in service life, the maintenance interruption time is shortened, the equipment utilization rate is high, mounting is convenient, and the screening effect is good.

Description

technical field [0001] The invention relates to a screening device, in particular to a disc screen. Background technique [0002] In garbage sorting, astrolabe screens are often used to subdivide materials. The star claws, the main components of the existing astrolabe screens, are prone to jamming and winding during the screening process, resulting in deformation, breakage, and Even if it is damaged, and the star claws are distributed in a claw shape, the bottom of the star claws is prone to stress concentration, which makes the star claws easy to damage and fall off, resulting in frequent replacement of the star claws, many stops in mechanical maintenance, low equipment utilization, and astrolabe parts. Complex, high processing and production costs. Contents of the invention [0003] To address one or more of the above problems, the present invention provides a dish screen. [0004] According to one aspect of the present invention, the disc sieve includes a frame with a...
