A robust pneumatic vibrating screen

Abstract

A steady pneumatic vibrating screen comprises a rack and a trough arranged above the rack. One end of the trough is fixedly connected with the rack, and an included angle of 15-30 degrees is formed between the trough and the rack. The trough is provided with a screen mesh for screening materials. The rack is formed by connecting four borders end to end, wherein the border b connected with the trough is arranged obliquely downwards, two vibrating springs are vertically arranged at the two ends of the border a corresponding to the border b, and the top ends of the vibrating springs are fixedly connected with the surface of the lower portion of the trough. According to the steady pneumatic vibrating screen, the problems that existing vibrating screens are small in yield, low in screening precision and the like are solved; by the adoption of the design that a pneumatic vibrating pump drives the screen to vibrate, the screen mesh is inclined and the vibrating springs are adopted, the working efficiency of the vibrating screen is doubled, the screening area is increased, and the purpose of improving screening efficiency is realized; and meanwhile the whole steady pneumatic vibrating screen has the advantages of being compact in structure, safe, steady, low in power consumption, convenient to install and the like.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a stable pneumatic vibrating screen. Background technique [0002] Vibrating screens are widely used in sand and gravel production lines, metallurgy, coal mines, mineral processing, building materials and other industries, and play an extremely important role in the process of bulk material bins. In recent years, with the rapid development of dry-mixed mortar products in China, dry powder equipment is also developing in the direction of intelligence and large-scale. If the existing vibrating screen is used in the field of construction machinery such as dry-mixed mortar, due to the limited driving capacity of the vibrating motor, the screen mesh of the vibrating screen is relatively small, the screening efficiency is low, and the screening accuracy is low, which affects the screen quality. Insufficient work efficiency also affects the effect, and cannot meet the needs of cus...

Problems solved by technology

If the existing vibrating screen is used in the field of construction machinery such as dry-mixed mortar, due to the limited driving capacity of the vibrating motor, the screen mesh of the vibrating screen is relatively small, the screening efficiency is low, and the screening accuracy is low, which affects the screen quality. Partial work efficiency also affects the effect, and cannot meet the needs of customers

[0003] With the continuous improvement of vibrating screen screening technology requirements, in order to improve the technical level of my country's equipment manufacturing industry and catch up with the advanced, the reform of vibrating screens is also imperative. At present, some domestic manufacturers have insufficient product structure when manufacturing vibrating screens. Stable, small rigidity, low strength, uneven force and easy slipping during use, unreasonable structural layout and other problems
