Relaxation screen

Abstract

The invention discloses a relaxation screen, and belongs to the field of material vibration screening. The relaxation screen structurally is composed of a support, a driving system, a shaft system, ashaft system protection cover, a guide plate, an inner box body, an outer box body, a screen cover and a cylindrical rubber seat. The driving system is fixed to the support and is directly connected with the shaft system. A shaft system protection sleeve is arranged on the outer side of the shaft system. The shaft system protection cover is externally fixedly connected with the inner box body andis connected with the outer box body through a push-pull rod in the horizontal direction. The inner box body and the outer box body are connected through a guide plate in the vertical direction. The screen cover is arranged above a screen box and is connected to the support through support legs. According to the relaxation screen, materials are ejected on a screen surface due to the downward loosening and upward tensioning movement of the screen, and the screening work of ejecting loosening and falling and screen penetrating is completed. The relaxation screen has the advantages of being highin efficiency and processing capacity, wide in application occasion, not prone to blockage, convenient to maintain and the like.

Description

technical field [0001] The invention belongs to the field of vibration screening of materials, and relates to a relaxation sieve, in particular to a flexible relaxation sieve capable of realizing the functions of particle size classification and self-cleaning screen surface. Background technique [0002] Vibrating screens are widely used in mining, smelting, chemical, material processing, food processing and other industries to separate loose industrial raw materials through specific structures. The screening of general materials can be regarded as composed of four stages: the static stage of materials, the materials just contact the screen, and stay on the screen. In this stage, the materials are relatively compact, and the screening of small particles is poor; the materials are loose. After several ejection movements, the material begins to loosen; in the stage of material stratification, the loose material passes through the projectile force and gravity of the screen, and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of the above-mentioned existing vibrating screens, such as complex structure, easy wear and tear of key components, and low working efficiency, and propose a relaxation screen. Ejection movement is carried out on the surface to complete the screening operation of bouncing loose and falling through the screen. It has high efficiency, strong processing capacity, many applications, is not easy to be blocked, and is easy to maintain. It can realize accurate and efficient separation of materials.
