Description

A three-layer adjustable composite vibrating screen

technical field

The utility model belongs to the field of vibrating screening machinery, in particular to a three-layer adjustable composite vibrating screen.

Background technique

The vibrating screen works through the reciprocating rotary vibration generated by the vibration of the vibrator in the vibrating motor. The movement of the upper rotating weight and the lower rotating weight of the vibrator causes the screen surface to produce conical surface rotary vibration, and the combined effect makes the screen surface produce reciprocating spiral vibration. At present, vibrating screens are often used in agriculture, aquaculture and other fields to screen out raw materials with different volumes. Existing vibrating screens can usually only screen out two kinds of mixed raw materials. The Chinese patent with the publication number CN203944546U discloses an ultrasonic vibrating screen with an application number of CN201420382597.6. The process separates the mixed raw materials through a single-layer screen, and only two kinds of raw materials can be separated; the Chinese patent with the publication number CN206215505U discloses a multi-layer vibrating screen, and its application number is CN201620985922.7. The device uses a motor to drive the conveyor belt and Centrifugal discs work, due to the simple vibration mode during the working process, the efficiency is not high and it is easy for the raw materials to block the screen.
