A Modular Fully Enclosed Circular Vibrating Relaxation Screen

Abstract

The invention discloses a modularized fully-enclosed circular vibration flip-flow screen, which comprises a main screen body, an elastic screen surface, a floating screen frame, a rubber shearing spring, a cylindrical rubber spring, a spring support seat, vibration exciters, a rack and a protective cover, wherein two ends of the elastic screen surface are fixed on a fixed beam of the main screen body and a floating beam of the floating screen frame through bolts separately; the floating screen frame is connected with the main screen body through the rubber shearing spring; the upper ends between two side plates of the main screen body are connected by using a reinforcing tube beam and the bottoms are connected by using a fixed beam; two vibration exciters are arranged on the left and right side plates separately; and the protective cover covers the whole main screen body to form a fully-enclosed structure. The relaxation quantity and the working amplitude of the flip-flow screen can be adjusted through replacing the modularized rubber shearing spring and the elastic screen surface, so that the flip-flow screen can adapt to different working condition requirements, a relatively good screening effect is ensured, the modularized fully-enclosed circular vibration flip-flow screen is simple in operation, reliable and effective, dust can be effectively reduced, the materials are prevented from being thrown out of the flip-flow screen and the health and safety of a worker are ensured.

Description

technical field [0001] The invention relates to a vibrating relaxation sieve, in particular to a fully enclosed circular vibrating relaxation sieve using modularized rubber shear springs and a screen surface, which is applicable to dry deep screening of materials under different working conditions. Background technique [0002] Vibrating screen is a very important screening equipment, which is widely used in mining, metallurgy, chemical industry, construction, road construction and sanitation industries. It is mainly used for screening, grading, washing, de-intermediation and dehydration of materials. When wet materials are subjected to dry deep screening, due to the surface tension of water, fine-grained materials are easy to agglomerate and harden, adhere to the screen surface, and block the screen holes, resulting in a decrease in screening efficiency and affecting the screening effect. [0003] The vibrating relaxation screen is a new type of vibrating screen for process...

Problems solved by technology

The method of adjusting the frequency of the excitation motor has the following problems: the vibrating screen needs to be equipped with a high-power frequency converter, which increases the cost of the equipment; the operation of the frequency converter requires relevant professional knowledge, and the technical requirements for workers are too high; the frequency conversion speed will make the motor overload state, the long-term speed increase will reduce the life of the motor and affect the performance of the motor

The screen surface is fixed with the card slot by buckle, the edge of the screen surface is zigzag, the processing technology is complicated, the cost increases, and if the saw tooth is damaged, it will not be fixed with the card slot
