Linear multi-layer grading vibrating screen and working method thereof

Abstract

The invention discloses a linear multi-layer grading vibrating screen and a working method thereof. The linear multi-layer grading vibrating screen comprises a vibrating screen box and a screen plate,wherein the screen plate is obliquely arranged in the vibrating screen box; a feeding port is formed in the upper part of the vibrating screen box, and the feeding port is right above a high-order end of the screen plate; a discharging port is formed in the side wall of the vibrating screen box, and an upper end part of the discharging port is connected with a low-order end of the screen plate; the side of the vibrating screen box is provided with a vibrating drive device, the vibrating drive device comprises a vibrating motor, a crankshaft, a shell, a first connecting rod, a second connecting rod and a third connecting rod, and the vibrating motor is arranged on the outer wall of the vibrating screen box; the crankshaft is vertically arranged in the shell; the end of the first connectingrod is hinged with a protrusion of the crankshaft, and the other end of the first connecting rod is connected with the first connecting rod, one end of the second connecting rod is connected with thescreen plate; and the third connecting rod is arranged on the inner wall of the vibrating screen box. According to the invention, the linear multi-layer grading vibrating screen has simple structuraldesign and is easy to manufacture and use; the number of the screen plate is even number and a vibrating direction at each time is opposite, which avoids resonance and improves the service life of equipment; and the same crankshaft can drive a plurality of screen plates at the same time, so energy is saved.

Description

technical field [0001] The invention belongs to the technical field of screening equipment, and in particular relates to a linear multi-layer grading vibrating screen and a working method thereof. Background technique [0002] Vibration screening is to separate and collect materials of different sizes and specifications after sieving. It is used in many industries, such as foundry, waste classification and utilization, graphite purification, flour processing, etc. During the operation of the vibrating screening device, the equipment will resonate with the vibration of the sieve plate. Usually, a complex structure is designed to avoid or reduce the resonance, resulting in a complex structure of the vibrating device, which increases the production cost of the enterprise and is difficult to maintain. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a linear multi-layer graded vibrating screen and its working method, which...
