Abstract

A closed bin type combined vibrating screen comprises a bin box bracket, a closed bin, a conveying belt and a single-layer vibrating screen; the bin box bracket is supported with a closed bin, two or more single-layer vibrating screens are arranged in the closed bin, and each vibrating screen is provided with a conveyer belt for conveying crushed stone materials with different specifications; the upper surface of the closed bin is provided with a dust discharge port connected with the dust remover, and the side surface of the closed bin is provided with an overflow port and a discharge port which are matched with the number of the vibrating screens. The screening area of the whole vibrating screen of the vibrating screen is fully utilized, so that stone is screened more thoroughly, and the screening efficiency is greatly improved. In addition, the screen sheet of the single-layer vibrating screen is easier to maintain and replace. The dust remover connected with the dust discharging port of the closed bin can collect all dust generated in the screening process, the dust is not overflowed, the production environment is changed, the personal health is guaranteed, and the environmental pollution is avoided.

Description

Closed bin type combined vibrating screen

Technical Field

The utility model relates to a broken building stones screening processing machinery especially relates to a closed storehouse formula combination shale shaker.

Background

In a broken stone production line, crushed stones are generally screened into a plurality of grades to meet the requirement of diversified stone specifications. The screening equipment can screen different specifications of the crushed stones with different sizes and different shapes, the stones which meet the requirement of granularity can be conveyed to a finished product area by the conveyor, and the stones which can not meet the requirement can be conveyed into the crusher to be crushed again. Currently, many screening devices are applied in the stone crushing industry, and mainly comprise various push-pull screen type vibrating screens. Most of the commonly used vibrating screens are multi-layer vibrating screens formed by arranging two or more layers of screening surfaces in the height of a screen body so as to realize the grading treatment of crushed stone materials. The multi-layer vibrating screen with the structural arrangement is characterized in that after the previous layer is screened, the next layer is screened for a certain distance to be screened. In fact, the effective screening area of the multilayer vibrating screen is a part of each layer of screen sheet, and the more the layers, the smaller the effective screening area. The effective screening area is small, the screening effect is poor, and the screening efficiency is low. Experiments show that the area of the effective screening part of the upper and lower combined four-layer screen is only one half of the whole screening area (see the attached figure 1, wherein the dotted part is the effective screening part). The multilayer vibrating screen is open, has no dust removal device, and has poor production environment and environmental pollution. The installation of dust-removing equipment requires a large amount of power and even a dedicated factory.

Disclosure of Invention

In order to solve the defects of the prior art, the utility model aims to provide a closed bin type combined vibrating screen which greatly increases the effective screening area.

Realize the utility model discloses a technical scheme that the purpose adopted is: a closed bin type combined vibrating screen comprises a bin box bracket, a closed bin, a conveying belt and a single-layer vibrating screen; the bin box bracket is supported with a closed bin, two or more single-layer vibrating screens are arranged in the closed bin, and each vibrating screen is provided with a conveyer belt for conveying crushed stone materials with different specifications; the upper surface of the closed bin is provided with a dust discharge port connected with the dust remover, and the side surface of the closed bin is provided with an overflow port and a discharge port which are matched with the number of the vibrating screens.

Compared with the prior art, the utility model has the advantages of it is following:

firstly because the utility model discloses an individual layer shale shaker is the front and back order and arranges, leans on the conveyer belt to carry the head of next shale shaker with the building stones of previous shale shaker screening. Therefore, the screening area of the whole vibrating screen is fully utilized, stone is screened more thoroughly, and the screening efficiency is greatly improved. In addition, the screen sheet of the single-layer vibrating screen is easier to maintain and replace. The vibrating screen is positioned in the closed bin, the dust remover connected with the dust discharge port of the closed bin can collect all dust generated in the screening process, and the dust does not overflow when the vibrating screen works under the condition of not taking environmental protection measures, so that the production environment is changed, the personal health is guaranteed, and the environment pollution is avoided.
