Dust catcher for belt conveyor with large inclined angle

Abstract

The invention relates to a dust catcher for a belt conveyor with a large inclined angle, and belongs to the technical field of environmental-friendly dry de-dusting. In the dust catcher, a belt blanking point is of a seal housing structure; an efficient settling chamber, a dust filter, a cycling separation chamber and a sealed chamber are sequentially arranged along the belt running direction from the blanking point; the position between the bottom parts of the efficient settling chamber, the dust filter, the cycling separation chamber and the sealed chamber and a mesh-type conveying belt is closed by protection plates at two sides; oblique flow deflectors are arranged on the inner walls of the protection plates, and lower ends of the flow deflectors are positioned within the range of corrugated baffle plates; and an air-flow balancing pipe is arranged on the lower end of a blanking pipe and is communicated with the efficient settling chamber. The dust catcher has the capability of preventing materials and dust from being deposited on a belt bottom plate, thereby avoiding secondary pollution and has high dust capture rate over 95%; the dust catcher has the advantages of low treatment cost, less investment, less occupied space, long service life and short construction period; in addition, gas discharged from an outlet of the dust catcher is lower than the national discharge standard.

Description

technical field [0001] The invention relates to a dust collector for a belt conveyor with a large inclination angle, and belongs to the technical field of environmental protection dry dust removal. Background technique [0002] The large inclination belt has the characteristics of large inclination angle conveying, compact structure, and less land occupation. It is an ideal equipment for large inclination angle conveying and vertical lifting of materials. use. The biggest feature of the large-inclination belt conveyor is that it uses a corrugated sidewall conveyor belt to replace the ordinary conveyor belt. Its working principle and structure are the same as those of the general belt conveyor. The conveyor belt is composed of a base belt, a diaphragm and a corrugated sidewall. formula structure. [0003] Most of the dust removal methods for large-inclination belts in my country adopt the bag dust removal process of centralized negative pressure suction. In the bag dust re...

AI Technical Summary

Problems solved by technology

Both factors require strong power. Once the dust is deposited inside the pipeline, the ventilation efficiency will be greatly reduced, the negative pressure state in the collection hood will be destroyed, the dust will overflow the collection hood, and the collection efficiency will be greatly reduced.

After one or two years of operation of the large-angle belt that adopts the bag dust removal process, the dust removal pipe is blocked, the dust removal system is paralyzed, and dust is flying at the dust point.

On the other hand, a certain amount of material and dust is deposited between the guide groove and the corrugated sidewall. When the belt enters the inclined part, the accumulated material and dust will slide off the base belt bottom plate of the belt, causing secondary dust pollution.
