Pressure relieving dust preventing and filtering system for dual-sealing arch-shaped material guiding chute

Abstract

The invention discloses a pressure relieving dust preventing and filtering system for a dual-sealing arch-shaped material guiding chute, and belongs to the technical field of dust treatment environmental protection equipment. The pressure relieving dust preventing and filtering system for the dual-sealing arch-shaped material guiding chute comprises the dual-sealing arch-shaped material guiding chute arranged over a belt, the material guiding chute communicates with a coal falling pipeline and is provided with a plurality of pressure relieving dust preventing and filtering devices and a plurality of adjustable dust shielding closing devices, and the pressure relieving dust preventing and filtering devices and the adjustable dust shielding closing devices are arranged at intervals; and a dual-sealing dust shielding box is arranged at an outlet of the dual-sealing arch-shaped material guiding chute. According to the pressure relieving dust preventing and filtering system for the dual-sealing arch-shaped material guiding chute, the design concept is advanced and unique, the system is simple in structure, small in size, low in weight and suitable for installation of the low position ina plant and equipment space, and the large plant building area does not need to be occupied.

Description

technical field [0001] The invention relates to the technical field of dust treatment and environmental protection equipment, in particular to a pressure-relieving and dust-proof filtering system for a double-sealed bow-shaped material guide groove. Background technique [0002] Because there is a certain drop between the head and the tail of the coal conveyor belt conveyor, a large amount of induced wind and air shock wave are generated during the blanking process, forming a strong positive pressure air flow in the material guide groove, and the strong positive pressure air flow guides the material. Spray out of the tank area, causing dust spray and dust around the equipment. [0003] The purpose of installing the dust collector is to create a vacuum effect in the material guide tank, and convert the positive pressure air flow in the material guide tank into a negative pressure air flow by means of air extraction and vacuum, and then pass the filter bag of the dust collecto...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a pressure-relieving and dust-proof filtering system for double-sealed bow-shaped material guide grooves to solve the problem that the head or tail of the existing coal conveyor belt conveyor cannot be installed with dust collector equipment due to the low height of the building space. The dust-laden air flow inside is continuously enhanced and diffused, and the dust-laden air flow (dust) that is enhanced and diffused will be ejected, diffused and fluttered to the outside of the trough area, seriously affecting the environmental quality.
