Self-turnover vibrating sieve bend

Abstract

The invention discloses a self-turnover vibrating sieve bend. The self-turnover vibrating sieve bend comprises a sieve box, a supporting frame and power assemblies, wherein the sieve box is arranged on the supporting frame, and the power assemblies are connected with the sieve box; the self-turnover vibrating sieve bend is characterized in that in the sieve box, each of the two ends of a sieve bend plate is respectively connected with a spring vibrating assembly; each of the spring vibrating assemblies comprises a spring and a vibrating motor connected with the spring, wherein the other surface of the spring is connected with the corresponding sieve bend plate; the middle part of the sieve box is connected with the supporting frame and connected by adopting a movable shaft; a double-lug connecting plate is arranged in the middle of the sieve box; the double-lug connecting plate is symmetrical by taking the supporting frame as the center; the two groups of power assemblies are respectively connected with one end of the double-lug connecting plate. The self-turnover vibrating sieve bend disclosed by the invention can complete the turnover automatically, the applied classifying efficiency is ensured by virtue of vibration of a sieve mesh and a fan-shaped structure of a sieve wire, and the service life is prolonged; the sieve bend does not need manual intervention, is long in service life, and high in classifying efficiency, so that the quality of the sieve bend is improved.

Description

technical field [0001] The invention relates to a curved screen, in particular to a self-turning vibrating curved screen. Background technique [0002] Curved sieve is an effective equipment for fine-grained slurry sieve classification, and is widely used in the classification and dehydration of fine-grained slurry in various departments such as mineral processing, coal preparation, cement, papermaking, grain processing and chemical industry. For example, for the de-intermediation, dehydration and desliming of fine-grained coal slime in the coal preparation system, the curved screen currently used is to fix the curved screen plate on the screen box, and the screen box is supported by columns. The bottom surface of the box and the horizontal plane have an inclination angle of 45°~60°. In order to increase the service life of the screen as much as possible, after the screen has been washed for a period of time, it is necessary to rotate the screen 180° in the plane where the s...

Problems solved by technology

At present, there are two kinds of this rotation process. One is to use manpower. About 8 to 15 people will turn the screen box and the curved sieve plate from the inclined state of 45° to 60° to the horizontal position, and then the screen box and the curved sieve plate can be rotated. The plate rotates 180°. After the rotation is completed, the screen box and the arc-shaped sieve plate are reversed by manpower to restore it to the use state with an inclination angle of 45°-60°. The entire operation process is neither safe nor time-consuming. The other is to use electro-hydraulic power to achieve flipping, such as the "Electric Flipping Arc Sieve" disclosed in the application number: 201020584282.1. Although this method solves the disadvantages of the first manual method, it still has structural instability and flipping cumbersome, short lifespan, etc.

Moreover, the classification efficiency of the curved screen directly determines the size and efficiency of the follow-up equipment and the quality of the final product. During use, it was found that the blockage of the screen surface has become an unsolved problem.
