Multilayer high-frequency vibrating screen

Abstract

The invention relates to the screening field, in particular to a multilayer high-frequency vibrating screen of superfine material screening such as oreconcentrate, medicine and the like, which is characterized in that a plurality of multilayer screen groups are arranged on a lower part bracket and a tail bracket of a main splitter; the lower parts of the multilayer screen groups are provided withvibration motors; a spring one is hinged and arranged between a high end and a bracket of the multilayer screen group; a spring two is arranged between a low end and the tail bracket of the multilayerscreen group; shunt pipes are arranged between the main splitter and splitters; a plurality of screen bodies are arranged on the multilayer screen groups in parallel; the splitters are respectively arranged at the entrance of each screen body; oversize products and undersize products enter a trough through the tail part of the screen body; an upper screen piece of the screen body is connected with a screen frame through a screen piece platen; a buffer slot is arranged at the end part of the screen piece; an isolation hood is arranged at the upper part of the whole screen frame; and valves arearranged at the shunting pipes. The invention has the beneficial effects of simple structure, convenient operation, reduced occupied area, improved screening ratio, low energy consumption and convenient screen piece replacement and maintenance.

Description

technical field [0001] The invention relates to the field of screening, in particular to a multi-layer high-frequency vibrating screen for screening fine materials such as concentrated ore and medicine. Background technique [0002] At present, high-frequency vibrating round sieves or high-frequency vibrating flat sieves are generally used in iron ore, gold ore and other mineral powder selection occasions or pharmaceutical screening and sorting occasions, which generally occupy a large area, low screening rate, and high energy consumption. Insufficient, there are also multi-layered sieve plates in order to increase the screening area, but there are problems of replacement of sieve plates and troublesome maintenance, which cannot fully meet the requirements of production. Contents of the invention [0003] The object of the present invention is to provide a multi-layer high-frequency vibrating screen, which can reduce the occupied area, improve the screening rate and facili...
