Variable-diameter crushing type dry powder fire extinguisher and fault elimination method thereof

Abstract

The invention discloses a variable-diameter crushing type dry powder fire extinguisher and a fault elimination method thereof, and belongs to the field of fire extinguishers. The variable-diameter crushing type dry powder fire extinguisher comprises a dry powder fire extinguisher body, wherein the upper end of the dry powder fire extinguisher body is connected with a spray head and a pressure handle, and the end, away from the pressing handle, of the spray head is connected with a powder spraying opening; a spray pipe is arranged in the dry powder fire extinguisher body, the upper end of the spray pipe extends into the spray head and fixedly communicates with the powder spraying opening, and a variable-diameter powder crushing mechanism is arranged on the inner side of the powder sprayingopening; and the variable-diameter powder crushing mechanism comprises a variable-diameter crushing structure, a screen grouping piece and a driving part, and the driving part comprises a micro driving device. The variable-diameter powder crushing mechanism is additionally arranged at the powder spraying opening, the agglomerated dry powder and the non-agglomerated dry powder are automatically separately to enter a coarse powder area and a fine powder area, the initial fine powder is directly sprayed out in time to extinguish fire, and the variable-diameter powder crushing structure is used for deeply grinding the agglomerated dry powder, so that the particle size of the sprayed dry powder is optimized, the fire extinguishing effect of the dry powder fire extinguisher is improved, and thepurpose of rapidly extinguishing the fire is achieved.

Description

technical field [0001] The invention relates to the field of fire extinguishers, more specifically, to a variable-diameter crushed powder dry powder fire extinguisher and a troubleshooting method thereof. Background technique [0002] A fire extinguisher, also known as a fire extinguisher, is a portable fire extinguishing tool. Fire extinguishers contain chemicals to put out fires. Fire extinguishers are one of the common fire prevention facilities and are stored in public places or places where fires may occur. [0003] Dry powder fire extinguisher is a kind of fire extinguisher. According to the type of dry powder fire extinguisher, it can be divided into: ① ordinary dry powder fire extinguisher; ② superfine dry powder fire extinguisher. [0004] The dry powder fire extinguisher is equipped with dry powder fire extinguishing agent such as ammonium phosphate salt. This dry powder fire extinguishing agent is easy to flow and dry. It is composed of inorganic salt and crushe...

AI Technical Summary

Problems solved by technology

With the continuous improvement of people's safety awareness, safety measures are more and more in place, and the frequency of fire incidents is getting lower and lower. Generally, the pre-prepared dry powder fire extinguishers are placed for a long time, and the dry powder in the cylinder is easy to agglomerate. The single crushed powder structure of the dry powder fire extinguisher is difficult to meet the crushing requirements of the agglomerated dry powder, resulting in poor fire extinguishing effect and low efficiency
