Movable foam abrasive jet fire-fighting cutting machine

Abstract

The invention discloses a movable foam abrasive jet fire-fighting cutting machine. The cutting machine comprises a fire-fighting cutting tool bit assembly, a high-pressure pipe, an abrasive mixing tank assembly, a supply pipeline, a mixing valve, a liquid A supply assembly, a liquid B supply assembly, a cutting machine power distribution cabinet, a booster pump, an explosion-proof motor, an unloading overflow valve, a safety valve, a pressure gauge, an energy accumulator, a coupling, a filter, a foam liquid assembly base frame, a liquid A pipeline, a liquid B pipeline, a heat exchanger, a pressure equalizer, a heat-sensitive controller, a hot-oil filter, a liquid inlet filter, a heat-sensitive circuit, a circulating pump, a frequency modulation motor, a three-way gate valve, an oil tank and a waterproof electric wire. The liquid A supply assembly and the liquid B supply assembly are used for pumping liquid A and liquid B into the mixing valve to form foam liquid, then the foam liquid is mixed with abrasive in the abrasive mixing tank assembly after passing through the booster pump, foam abrasive jet is formed, and then the foam abrasive jet is accelerated to a supersonic speed through a nozzle of the fire-fighting cutting tool assembly to impact a to-be-cut object, and fire-fighting foam is generated in the cutting process so as to realize fire-fighting cutting.

Description

technical field [0001] The invention relates to a mobile foam-abrasive jet fire-fighting cutting machine for emergency relief and fire-fighting rescue. Specifically, when cutting dangerous chemicals that are flammable and explosive in the air, or when cutting obstacles in fire rescue, the liquid that can produce fire-fighting foam will be pressurized through the supercharger and mixed with the mixing valve. Abrasives are mixed in proportion and accelerated through the nozzle to form a foamy abrasive jet; this kind of foamy abrasive jet produces fire-fighting foam while cutting dangerous chemicals, covering the cutting edge, thus a device for emergency rescue and fire rescue. This device that integrates fire rescue and emergency rescue is called a mobile foam abrasive jet fire cutting machine. It belongs to the field of fire rescue. Background technique [0002] In the process of production, storage, transportation, use of flammable, explosive and hazardous chemicals, and f...
