Multilayer sealed vibrating screen with screen cloth convenient to replace

Abstract

A multilayer sealed vibrating screen with screen cloth convenient to replace comprises a screen body, a feeding port opened upwards and a discharging port opened downwards are formed in the right endand the left end of the screen body respectively, a first screening cloth bracket, a second screening cloth bracket and a third screening cloth bracket are stacked in an inner cavity of the screen body from bottom to top in sequence, screen cloth is arranged on the first screening cloth bracket, the second screening cloth bracket and the third screening cloth bracket, a material receiving assemblyinstalled in cooperation with the first screening cloth bracket, the second screening cloth bracket and the third screening cloth bracket is further arranged in the discharging port, a screen cloth pressing frame is further arranged at the upper end of the third screening cloth bracket, a screen lifting device is further arranged on the screen body, a blocking plate is movably installed at the right end of the screen body, and a dust-proof cover is further arranged at the upper end of the screen body. The multilayer sealing vibrating screen is novel in concept and ingenious in mechanism, andmaterials are screened in the sealed screen body to reduce environment pollution; and besides, the screen lifting device is arranged and used for replacing or repairing the screen cloth on the condition that not too many bolts are disassembled, the working efficiency is greatly improved, and the working intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to a multi-layer sealed vibrating screen which is convenient for replacing the screen mesh. Background technique [0002] At present, the scope of application of the vibrating screen is very wide, and it needs to be used in processing and manufacturing, and it involves almost all aspects of life. Vibrating screens are mainly used in petroleum, coal, smelting, building materials, refractory materials, light industry, chemical industry, medicine, food and other industries. When the vibrating screen is working, dust is flying. Most of the existing vibrating screens are in a semi-sealed state and cannot meet environmental protection requirements. It is to screen and distinguish ores of different sizes through vibrating screens and apply them to different occasions. However, during the screening process of the ore, multiple screenings are required to obtain ores with differe...

AI Technical Summary

Problems solved by technology

However, in the screening process of ore, multiple screenings are required to obtain ores with different particle sizes, which not only increases the difficulty of screening, but also has low efficiency.

At the same time, when the vibrating screen is working, the dust is flying, and most of the existing vibrating screens are in a semi-sealed state, which cannot meet the environmental protection requirements

[0003] In addition, when using a vibrating screen with multiple layers of screens, if one of the screens is damaged, the entire screen combination composed of multiple layers of screens must be removed, and then the screens must be replaced, which is cumbersome and inefficient to replace. Do a single disassembly of the damaged screen, affecting production efficiency
