specific Embodiment approach 1

[0010] Specific implementation mode 1. Combination figure 1 and figure 2 Illustrate this specific embodiment, the gas recoil type fast explosion-proof device of coal mine excavation working face, it comprises support frame 1, explosion-proof door 2, explosion-proof plate 3, two fan explosion-proof windows 4, crossbeam 5, vertical suspension beam 6, electromagnetic Armature 14, spring 15 and control system, support frame 1 is divided into upper and lower parts by beam 5, the left side of explosion-proof plate 3 is fixed on the left side of the lower part of support frame 1, and the explosion-proof plate The right side of 3, the crossbeam 5 and the right side of the supporting frame 1 form a door frame, and the blast door 2 is hinged with the door frame; The other end is in contact with the upper surface of the crossbeam 5; the upper part of the support frame 1 is divided into left and right parts by the vertical suspension beam 6, and the two explosion-proof windows 4 are res...

specific Embodiment approach 2

[0015] Embodiment 2. The difference between this embodiment and the gas recoil type rapid explosion arresting device for coal mine mining face described in Embodiment 1 is that the explosion arrester 2 is composed of a foam ceramic base layer 21 and a barbed wire layer 22. The barbed wire layer 22 is covered and fixed on the inner and outer surfaces of the ceramic foam base layer 21 .

[0016] In this embodiment, the material of the explosion-proof plate 3 and the explosion-proof door 2 is the same.

[0017] In this embodiment, the function of the coal mine gas and coal dust automatic barrier explosion isolation device is to eliminate the hazards and influences of high-temperature burning of the flame front, shock wave overpressure damage, and poisonous and harmful gases in shafts during gas and coal dust explosions. At the same time, it should have repeated functions. And usability, it can play a role in preventing secondary explosions or multiple explosions after underground...

specific Embodiment approach 3

[0018] Specific Embodiment Three. The difference between this specific embodiment and the gas recoil type rapid explosion arresting device for coal mining face described in specific embodiment one or two is that it also includes N anti-collision liners 7, and the N The anti-collision liner 7 is distributed and fixed on the right side of the explosion-proof plate 3, and the N is a positive integer.

[0019] The crash pad 7 in this embodiment is a copper crash pad.

Abstract

The invention provides a blowback fast explosion suppression device for a coal mining working face, and relates to a blowback fast explosion suppression device, which is used for solving the problem that shock wave and flame caused by explosion can not be effectively prevented in the existing coal mining working face. The blowback fast explosion suppression device is equipped with an explosion suppression door and two explosion suppression windows; and in case of explosion, a control system controls the explosion suppression door and the two explosion suppression windows to be closed so as to play the role of suppressing explosion. The blowback fast explosion suppression device is applicable to a roadway of a coal mine.

Description

technical field [0001] The invention relates to a gas recoil type rapid explosion arresting device. Background technique [0002] Gas and coal dust explosion is a major safety problem that needs to be solved urgently in the coal production industry, and it is necessary to carry out research work on its prevention and control. Since the "Sixth Five-Year Plan", a series of explosion-proof and explosion-suppression devices successfully developed and applied in coal mining enterprises in my country can be divided into two categories: passive explosion suppression and automatic explosion suppression according to different explosion suppression methods. [0003] The passive explosion-proof technologies adopted by coal mining enterprises mainly include explosion-proof water tanks, water bags and rock powder sheds. The principle is to use the energy of the explosion shock wave itself to act on the anti-explosion agent pre-set in the explosion propagation channel to form a certain s...
