Technical Field
[0001] The utility model relates to the technical field of dry powder fire extinguishers, in particular to a tank body closing structure of a dry powder fire extinguishing device. Background Technique
[0002] The inside of a dry powder fire extinguisher is filled with dry powder extinguishing agents such as ammonium phosphate. This kind of dry powder extinguishing agent has fluidity and dryness, and is composed of inorganic salts and crushed and dried additives, which can effectively extinguish incipient fires. There is an existing patent on the nozzle structure of a dry powder fire extinguisher. The patent publication number CN219355171U includes a tank body. The bottom of the tank body is equipped with a tank bottom, and the top of the tank body is equipped with a connection component. The top of the connection component is equipped with a nozzle structure. For this dry powder fire extinguisher nozzle structure, a fixed pressure cover is used to stabilize the centrifugal tube and the collar to achieve a certain degree of stability. The structure of opening the nozzle by a regulating valve is used, and the length of the nozzle is extended through a stretching tube to increase the fire extinguishing range and act on the through tube. Among them, the nozzle of the nozzle adopts a choke plate type nozzle, which plays an atomizing role during spraying operations. The high-speed air flow blows the dry powder in the dry powder bin transported to the nozzle into fine droplets, and the high-speed air flow flowing out from the outlet of the small centrifugal fan in the centrifugal tube passes through the spray tube to the nozzle. At this time, the cross-sectional area at the nozzle becomes smaller, so that the flowing air flow speed increases, and a negative pressure is formed around the nozzle, thereby realizing fine powder output of the dry powder and being able to quickly extinguish the fire.
[0003] Regarding the above related technologies, the applicant believes that there are the following defects: when it is in use, although centrifugation can be carried out through the centrifugal tube, when it is in use, due to the fixed orientation of the closing structure, after the dry powder fire extinguisher is assembled, it cannot quickly adjust the spraying direction according to actual needs, which has limitations.
