Dust explosion suppression device

Abstract

The invention discloses a dust explosion suppression device, belonging to the technical field of mine safety facilities. The dust explosion suppression device comprises a tank body, a tail cover, an adaptive seat, a nozzle, a seal disc, a gas generation mechanism and an ignition mechanism, wherein the tank body is provided with a powder extinguishing agent storage cavity; the tail cover is configured on the port part of one end of the tank body; the adaptive seat is arranged in the center of the tail cover and faces to one side of the powder extinguishing agent storage cavity; the nozzle is configured on the port part of the other end of the tank body and is gradually expanded from the tank body to the direction far away from the tank body to form a trumpet shape; the seal disc is arranged in a film disc cavity on the tank body; the gas generation mechanism is positioned in the powder extinguishing agent storage cavity and is fixed with the adaptive seat; and the ignition mechanism is also adaptive with the gas generation mechanism. The dust explosion suppression device is characterized by also comprising a moving rack; one end facing to the nozzle, of the moving rack is provided with a lifting regulation mechanism; the lifting regulation mechanism is connected with the tank body or the nozzle; and the tail cover is connected with the pivot of the moving rack. The dust explosion suppression device has the advantages that in-field setting requirements can be satisfied, the dust explosion suppression device has ideal maneuverability, idle and waste device resources can be prevented, an injection area can be enlarged, and gas and / or dust explosion flame can be quickly put out.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety facilities, and in particular relates to a dust explosion suppressing device, which is mainly used for suppressing coal mine dust explosion, and can also be used for suppressing dust explosion in industries such as flour, wood powder and fine chemical industry. Background technique [0002] According to the fire protection requirements, such as portable dry powder fire extinguishers and handcart dry powder fire extinguishers and corresponding sprinkler fire extinguishing equipment must be equipped in the occasions not limited to the above examples, but because these facilities need to be operated manually, the timing is often delayed, and Slow movement is not enough to fully guarantee the safety of life and property. [0003] The technical information about the dust explosion suppression device has been found in the published Chinese patent documents, such as the utility model patent auth...

Problems solved by technology

[0002]According to the fire protection requirements, the occasions not limited to the above examples must be equipped with portable dry powder fire extinguishers, handcart dry powder fire extinguishers and corresponding sprinkler fire extinguishing equipment, but Because these facilities need to be operated manually, the timing is often delayed and the action is slow, which is not enough to fully guarantee the safety of life and property.

[0003]The technical information about the dust explosion suppression device has been found in the published Chinese patent documents, such as the utility model patent authorization announcement number CN201277056Y (storage pressure type Gas and dust explosion suppression device), this patent scheme has at least the following deficiencies: First, the structure of the nozzle is unreasonable, resulting in the sprayed fire extinguishing agent tending to be columnar, that is, the spray coverage area is limited; second, the lack of mobility, when using The site installation is more troublesome; the third is that the angle of the tank and the nozzle cannot be adjusted as needed

[0004] Compared with CN201277056Y, the gas-generating explosion suppressor recommended by CN201578778U has a more reasonable nozzle structure, forming a trumpet shape, which has contributed to expanding the spray surface, but does not have Mobility and angular adjustability of the tank are its drawbacks

[0005] CN201211404Y provides the nozzle of the gas dust explosion suppression device which is opposite to CN201578778U, which can make the coverage of spraying fire extinguishing agent expand extremely, however, the angle of the tank and the nozzle cannot be changed It is a pity that the poor adaptability of the use site

In addition, due to the lack of mobility, for example, it is often confused when it is to be installed on the ground, that is, the installation is more troublesome
