Rubber powder vibrating screen

Abstract

The invention discloses a rubber powder vibrating screen which is mainly composed of a rack, a screen box, a screen net and a vibration motor, wherein the screen box is arranged on the rack; the vibration motor is connected with the screen box, and the screen box is driven by the vibration motor to make horizontal straight reciprocating motions; the screen box comprises a vibration cavity and a discharging cavity; the screen net is fixed in the vibration cavity and divides the vibration cavity into at least two layers, namely a feeding layer which is located above the screen net and a discharging layer which is located below the screen net; the upper part of the discharging cavity is connected with the lower part of one side wall in the movement direction of the vibration cavity, and the upper part of the discharging cavity is communicated with the discharging layer of the vibration cavity; and a screen box feeding opening is formed at the upper part of the vibration cavity, and a screen box discharging opening is formed at the lower part of the discharging cavity. The rubber powder vibrating screen can effectively prevent materials from being stacked and plugged in the screen box, and has the characteristics of high screening efficiency and good screening effect.

Description

technical field [0001] The invention relates to the field of rubber powder production, in particular to a rubber powder vibration sieve. Background technique [0002] Rubber powder is the abbreviation of rubber powder, which is widely used in sports plastic sports fields, playgrounds, rubber floor tiles, waterproof membranes, waterproof coatings, road rubber modified asphalt, high-speed railway composite sleepers, rubber and plastic products and other fields. Rubber powder is mainly processed by crushing and sieving waste rubber such as waste tires into rubber particles of different meshes, and then adding corresponding doses of active agents according to different functions. [0003] At present, rubber particles are generally screened by vibrating screens. As shown in the Chinese invention patent with the notification number CN202061799U, traditional vibrating screens are mainly composed of a frame, a screening motor, a screen box and a screen. The screen box is fixed abov...

AI Technical Summary

Problems solved by technology

[0004] The vibrating screen with the above structure has the following disadvantages in the actual use process: since the discharge direction and the material movement direction are not in the same plane, the rubber particles falling from the screen will first hit the inclined side wall of the collection chamber After deceleration, slide down to the discharge port along the inclined side wall of the collection chamber, which will easily lead to the accumulation of materials in the collection chamber, resulting in the occurrence of material blocking
