Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, the dust suppression and dedusting device of the fully mechanized mining face of the present invention includes two parts: a coal mining machine control-dust removal device and a hydraulic support control-dust removal device; wherein:

[0044] The shearer control-dust removal device is based on the original internal and external spray dust removal equipment of the shearer 1 and the air curtain dust control equipment of the shearer, behind the two cutting parts 3 of the shearer, close to the shearer At the position of the control part 2, a group of air curtain nozzles 9 are respectively installed; wherein, each group of air curtain nozzles 9 includes several air flow nozzles, and the central axis of the outlet of each air flow nozzle is in the same plane as the cutting part where it is located. into the same angle;

Abstract

The invention discloses a dust suppressing and removing device for a fully mechanized coal mining face. The technical thought of performing dust prevention and control from the source is adopted; a group of air curtain nozzles for jetting air current is arranged behind two cutting parts of a coal mining machine and close to a control part of the coal mining machine respectively, thereby forming air walls wrapping fog fields formed by spray dedusting equipment inside and outside the coal mining machine respectively on two drums of the coal mining machine; a bracket spray dedusting device and a bracket dust absorbing and purifying device are arranged on each bracket respectively in order to effectively precipitate or absorb a large amount of dust falling from both sides and the front of the brackets and dust overflowing from a control-dedusting system of the coal mining machine in a precipitating or absorbing bracket-moving process. Compared with the prior art, the dust suppressing and removing device for the fully mechanized coal mining face disclosed by the invention has the advantages of good dust prevention and removal effects; the device is easy and convenient to operate, is small in investment, and has good market application prospect and popularization value.

Description

technical field [0001] The invention relates to an underground coal mine dust control and dedusting technical equipment, in particular to a fully mechanized mining face dust suppression and dedusting device. Background technique [0002] As an inevitable product in the process of coal production and processing, mine dust has become one of the five major disasters in coal mines due to its physical and chemical characteristics. [0003] The main hazards of mine dust include two aspects: one is the spontaneous combustion and explosiveness of coal dust; the other is occupational disease hazards. The coal mining face has always been the first source of dust production in coal mining enterprises, and the dust production accounts for more than 85% of the dust production in the entire mine. The dust produced by shearer cutting accounts for the vast majority, but the dust produced by moving the frame still cannot be ignored. Among them, the dust produced by the self-moving hydraulic...
