Abstract
The utility model discloses a pressure accumulating type gas and dust explosion suppressor, which comprises a tank body, wherein the external of the tank body is equipped with a jet nozzle, and the internal of the tank body is equipped with a dry powder fire-extinguishing agent and a high-pressure air bottle. The mouth of the high-pressure air bottle is equipped with an explosive cutting valve, the explosive cutting valve is connected with an electrical connector for connecting an control mechanism via wires, the high-pressure air bottle is connected with a bottle valve and a pressure gauge via pipes, and the electrical connector, the bottle valve and the pressure gauze are mounted on an cover of the tank body. The pressure accumulating type gas and dust explosion suppressor has reasonable design and simple structure. By utilizing technique of the explosive cutting valve and the sector jet nozzle, speed of dusting action becomes fast, effective covering area is enlarged, thereby the pressure accumulating type gas and dust explosion suppressor is an ideal explosion suppressing device in tunnel and pipeline systems.
Description
Technical field
The utility model relates to a kind of antiknock device, particularly a kind of elastic energy storing style gas, dust explosion explosion suppression device.
Background technology
At present, underground mine use has only the datonation-inhibition tank of passive type, water bag in the equipment that prevents gas, coal-dust explosion, its operating principle is to rely on the blast pressure of gas, coal dust smash, throw tank or water bag is broken off relations, before transmitting, explosive flame forms water smoke, put out explosive flame subsequently, reach datonation-inhibition purpose.The prerequisite of above-mentioned passive type explosion suppression device action is, gas, coal dust pressure must reach more than the 12kPa, otherwise tank or water bag is broken off relations is difficult to smash, throws, can't form desirable water smoke state, because the randomness that gas, coal-dust explosion take place, trigger datonation-inhibition tank, water bag blast pressure size can't guarantee, therefore, the datonation-inhibition effect of passive type explosion suppression device also just is difficult to guarantee.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of quick action that dusts, elastic energy storing style gas, dust explosion explosion suppression device that area of effective coverage is big are provided.
The technical solution of the utility model is: a kind of elastic energy storing style gas, dust explosion explosion suppression device, comprise tank body, it is characterized in that: the outer setting of described tank body has nozzle, and powder extinguishing agent and gas cylinder are equipped with in the inside of tank body, and blast cutting valve is installed on the port of gas cylinder; Described blast cutting valve is by lead and the power point connection that is used to be connected controlling organization, and gas cylinder is connected with pressure meter with bottle valve by pipeline, and described power point, bottle valve and pressure meter are installed on the end cap of tank body.
The utility model compared with prior art has the following advantages:
The utility model is reasonable in design, and is simple in structure, owing to adopt blast cutting valve technology and fan nozzle, so response speed is fast, and the area coverage of dusting is big, is the desirable explosion suppression device of mine laneway and pipe-line system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of elastic energy storing style gas as shown in Figure 1, dust explosion explosion suppression device comprise tank body 4, and the outer setting of described tank body 4 has nozzle 9, and powder extinguishing agent 6 and gas cylinder 5 are equipped with in the inside of tank body 4, and blast cutting valve 7 is installed on the port of gas cylinder 5; Described blast cutting valve 7 is by lead and power point 3 connections that are used to be connected controlling organization, and gas cylinder 5 is connected with pressure meter 1 with bottle valve 2 by pipeline, and described power point 3, bottle valve 2 and pressure meter 1 are installed on the end cap 11 of tank body 4.
Described nozzle 9 is communicated with tank body 4 by the flange 10 that is installed in tank body 4 bottoms.
Junction at flange 10 and tank body 4 is provided with moistureproof barrier film 8.
Be the area coverage that increasing is dusted, described nozzle 9 is a fan nozzle.
The utility model is installed on the both sides, tunnel of easy generation gas or coal-dust explosion, or is installed on other damp, the dust conveyance conduit, and the blast information probe is installed on the place ahead of the present utility model.When gas, coal-dust explosion take place when, the blast information probe receives detonator signal, and transmits signals to controller, and controller produces trigger current, electric current causes 7 actions of blast cutting valve by power point 3, thereby gas cylinder 5 is opened rapidly, discharged gases at high pressure, the powder extinguishing agent 6 that drives in the tank body 4 sprays from nozzle 9, form the extinguishing chemical dust cloud body of enough concentration, fully contact with flame, stamp out the flames, prevent generation, the development of gas, coal-dust explosion.Pressure meter 1 and switch valve 2 are used to check the pressure of gas cylinder 5 and are its inflation.
