Multi-layer closed vibrating screen

Abstract

The invention discloses a multi-layer closed vibrating screen. The multi-layer closed vibrating screen comprises a machine shell. A cover plate is arranged on the top of the machine shell. A feeding cylinder fixedly mounted on the cover plate penetrates the cover plate and is connected with a screening bin arranged in the machine shell. Fans fixed to the cover plate are arranged in the screening bin. A first filter screen, a second filter screen, a third filter screen and an inclined plate are sequentially arranged in the screening bin from top to bottom. The right side of the first filter screen, the right side of the second filter screen and the right side of the third filter screen are all rotationally connected with the inner wall of the machine shell through pin shafts. A rotary disc is fixedly mounted at the top end of a transmission shaft of a motor. A first discharging opening, a second discharging opening, a third discharging opening and a fourth discharging opening which are sequentially arranged from top to bottom are fixedly mounted at the right side end of the machine shell. According to the multi-layer closed vibrating screen, the reasonable structural design is adopted, the operation is simple, materials can be well vibrated and screened, dust can be reduced effectively, and the body health of working staff is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vibrating screen equipment, in particular to a multi-layer closed vibrating screen. Background technique [0002] At present, with the rapid development of my country's economy and the improvement of industrial production levels, vibrating screens, as a new type of high-efficiency screening and separation equipment, are widely used in coal, ore and other industries, especially in ore screening. The use of vibrating screens The production efficiency has been greatly improved, but the existing ore vibrating screens are often open, not only there is huge mechanical noise, but also it is easy to generate dust during the working process to pollute the environment, and at the same time, it has a negative impact on the health of the staff. Great harm. Contents of the invention [0003] The purpose of the present invention is to provide a multi-layer closed vibrating screen to solve the problems raised in the ab...
