Sandblasting fire extinguishing device, sandblasting fire extinguishing vehicle and sandblasting trailer

Abstract

The invention discloses a sandblasting fire extinguishing device, a sandblasting fire extinguishing vehicle and a sandblasting trailer. The sandblasting fire extinguishing device comprises a cargo compartment assembly and a spraying system. The cargo compartment assembly comprises a compartment, a conveying belt, a guide mechanism, a rotary unloader and a mixing chamber. The spraying system comprises a fan and a pressure control component. Gas produced during rotating of the fan enters the mixing chamber after the pressure of the gas is adjusted through the pressure control component. The mixing chamber is connected with a spraying pipeline. The sandblasting fire extinguishing device can form the sandblasting fire extinguishing vehicle or the sandblasting trailer through traction of different carriers, fast travels to arrive at a scene and can work while travelling, fire extinguishing agent materials are fast and continuously sprayed to a fire area at a long distance, the requirement for fire extinguishing under various conditions can be met, the problem that currently, no mechanical fire fighting equipment using sandy soil or other solid fire extinguishing materials exists is solved, and the efficiency for suppressing special fire disasters such as hazardous chemical fire and fluid flow fire and the rescue safety are greatly improved.

Description

technical field [0001] The invention relates to the field of emergency rescue, in particular to a sandblasting fire extinguishing device, a sandblasting fire extinguishing vehicle, and a sandblasting trailer. Background technique [0002] In recent years, with the increasing number and scale of enterprises related to flammable and explosive dangerous goods in my country. The frequency and scale of fire and explosion accidents caused by hazardous chemicals during production, storage and transportation have also increased. Cause a large number of casualties, property loss and environmental pollution, bring immeasurable loss to the society. In the process of fighting a hazardous chemical fire, especially when a water-avoiding hazardous chemical fire cannot be extinguished with water, foam, or carbon dioxide, sand is usually used to cover the fire. At present, the fire is extinguished manually by using tools such as sand buckets and shovels to cover materials or by dumping and...

Problems solved by technology

[0004] Patent 201510824865.4 discloses an automatic sandblasting fire truck, which mainly uses negative pressure to suck materials into the cyclone separator. The cyclone separator is installed above the sand storage container. When the cyclone separator is actually used, it must reach a certain processing capacity and the required height Higher, so the height of the vehicle will be too high; and the three-way valve is directly connected to the sand and gas input and output ports, and the sand is easy to block the valve port

[0005] Patent 201720136104.4 discloses a sandblasting fire truck. The sand stored in the sand storage tank flows out of the tank through gas pressure. The density of the sand is relatively high and the pressure required is relatively high, which results in high power and power loss of the vehicle. Big
