Description

High-precision double-layer bar type vibrating screen

Technical Field

The utility model relates to the technical field of vibrating screens, in particular to a high-precision double-layer bar type vibrating screen.

Background

The vibrating screen works by utilizing reciprocating rotary vibration generated by vibrator excitation. The upper rotary weight of the vibrator makes the screen surface produce plane rotary vibration, while the lower rotary weight makes the screen surface produce conical surface rotary vibration, and the combined effect of the upper rotary weight and the lower rotary weight makes the screen surface produce compound rotary vibration. The vibration track is a complex space curve. The curve is projected as a circle on the horizontal plane and as an ellipse on the vertical plane. The vibration force of the upper and lower rotary weights is adjusted to change the amplitude. And the curve shape of the movement track of the screen surface and the movement track of the material on the screen surface can be changed by adjusting the space phase angles of the upper heavy hammer and the lower heavy hammer. Mainly comprises a screen box, a vibration exciter, a suspension (or supporting) device, a motor and the like. The motor drives the main shaft of the vibration exciter to rotate through the triangle belt, and the screen box is vibrated due to the centrifugal inertia force action of unbalanced weights on the vibration exciter. The eccentric weight of the vibration exciter is changed, and different amplitudes can be obtained. The vibrating screen is mainly divided into a linear vibrating screen, a circular vibrating screen and a high-frequency vibrating screen. The vibrating screen can be classified into a single-shaft vibrating screen and a double-shaft vibrating screen according to the type of vibrator. The single-shaft vibrating screen is characterized in that a screen box is vibrated by utilizing single-unbalanced weight excitation, the screen surface is inclined, and the movement track of the screen box is generally circular or elliptical. The double-shaft vibrating screen is excited by utilizing a double-unbalanced weight which synchronously rotates in different directions, the screen surface is horizontal or slightly inclined, and the movement track of the screen box is a straight line. The vibrating screen is of the types of an inertial vibrating screen, an eccentric vibrating screen, a self-centering vibrating screen, an electromagnetic vibrating screen and the like.

The bar type vibrating screen disclosed in the Chinese patent application publication No. CN207478971U has the following defects that the bar type vibrating screen can improve screening effect and regulate material flow when in use: 1. when screening, the material is easy to block in the gaps of the bar screen, the material is easy to block, most of the blocking removing modes are manual, time and labor are wasted, screening efficiency is affected, dust is easy to swing when screening is carried out, and therefore working environments near the vibrating screen are poor, and physical health of workers is affected.
