Description

TECHNICAL FIELD [0001] The present invention relates to a device for automatically dismantling a waste powder fire extinguisher,

More particularly, the present invention relates to an automatic disintegration device for waste powder (extinguisher powder extinguisher) which can be safely disassembled safely using universal use regardless of the size of a fire extinguisher, To a powder fire extinguisher capable of collecting powdered fire extinguishing agent.

Fire extinguishers are mainly classified as powder fire extinguishers, gas fire extinguishers, liquid and foam fire extinguishers, and clean fire extinguishers. Among them, the powder fire extinguisher is a device which presses or axially presses the fine powder for fire extinguishing as a fire extinguishing agent in the container of the main body and emits it, and it is made of iron parts (main container, lever, safety pin, gas container for pressurization), aluminum parts Discharge tube, etc.), rubber resin parts (hose, nozzle, etc.), and dry chemical powder.

These powder fire extinguishers are usually disassembled after the main container has been corroded or durably used (some years), and some parts are recycled and disposed of.

Especially, ABC powder fire extinguishers which can be used for general fire, oil, electric fire, etc. are mostly used ammonium phosphate (NH ₄ H ₂ PO ₄ ) as a main component. Phosphorus, which is a raw material of ammonium phosphate, And it is currently being recycled (recycled after re-processing) by collecting powdered fire extinguishing agents.

However, due to the nature of the pressure vessel in the absence of powdered fire extinguishing agent or gas in the powder fire extinguisher, it is ruptured in the course of manual dismantling (disassembly) by the worker such as stoneware or recycling company The risk is high.

For example, when the pressurized powder fire extinguisher does not contain any pressure in the main body container but presses the pressurizing gas container to press the lever to actuate the extinguisher, the pressurized gas container (filled with CO ₂ ) The pressure is guided into the main body container and the powdered fire extinguishing agent is discharged to the outside through the hose. The pressure of the pressurizing gas container may be ruptured when the bottom portion of the main body container is severely corroded in the process of transferring pressure to the main body container, At this time, the container of the main body protrudes by the repulsive force, and the head or neck of the firearm operator can be priced, leading to an accidental accident.

Also, if the hose leading to the outside of the main body container is clogged and the pressurized gas induced by the medicine can not be ejected, a fatal accident may occur due to separation from the main body container around the corroded portion (generally the lower portion of the main body container).

On the other hand, in the case of a pressure-type powder fire extinguisher, the main container itself may be blown out due to the structural characteristics of the pressure container, such as the disassembling process of the main container.

Furthermore, there is a problem that the powdered fire extinguishing agent is scattered in the process of manually collecting the powdered fire extinguishing agent inside the powder fire extinguisher by hand, thereby causing environmental accidents in the workplace and causing a safety accident such as causing respiratory disease of the worker.

In addition, when the powder fire extinguishing agent is agglomerated in the main container of the powder fire extinguisher or is adhered to the inner wall surface of the main container, the discharge is not smooth and the efficiency of the work is considerably decreased and an excessive time is required for the collection work .

Herein, the background art or the prior art described above is only intended to help understand the technical significance of the present invention as information acquired by the present inventor or derived from the present invention, It does not mean that it is widely known in the field.
