A device for automatically preparing foam stock solution from foam powder

Abstract

The invention discloses a device for automatically preparing foam stock solution from foam powder, which comprises a mixing barrel, a foam stock solution storage tank, a foam powder storage tank and a driving platform for driving the foam powder storage tank to lift and rotate. The top is provided with a powder adding hole, the mixing tank is provided with an agitator, and the upper part of the mixing tank is provided with a water inlet, and the lower part is provided with a foam stock solution outlet, and the foam stock solution outlet is connected with a foam stock solution storage tank; The foam powder storage tank includes a tank body, the peripheral side wall of the tank body is divided into a closed part and an open part from top to bottom, a fixed sleeve is arranged on the outer periphery of the tank located at the closed part, and a A movable sleeve is arranged on the outer periphery of the tank, and an up and down telescopic structure is formed between the fixed sleeve and the movable sleeve, and the inner diameter of the powder adding hole is between the outer diameter of the tank body and the outer diameter of the movable sleeve between sizes. The invention can realize the automatic preparation of the foam stock solution from the foam powder at the fire scene.

Description

technical field [0001] The invention relates to a device capable of automatically preparing foam stock solution from foam powder at a fire scene, and belongs to the technical field of fire-fighting equipment. Background technique [0002] Fire-fighting foam liquid, that is, aqueous film-forming foam fire extinguishing agent, also known as light water foam fire extinguishing agent, also known as foam liquid, foam stock liquid or foam concentrate, is usually composed of foam powder (composed of surfactants and additives to improve foam performance) and made with water. [0003] The use of foam fire extinguishing agent for fire extinguishing has the advantages of cleanness, environmental protection, and convenient use. For example, it is non-toxic, tasteless, and dust-free when extinguishing fires. It will not cause secondary pollution to the environment and will not damage the ozone layer of the atmosphere; it can be used to extinguish Class A fires. , such as the fire caused...

AI Technical Summary

Problems solved by technology

Due to the limited volume of the fire truck, the foam stock solution takes up a large volume, so that the amount of foam stock solution that the fire truck can carry is limited, which cannot meet the long-term fire extinguishing needs, thus affecting the timely fire extinguishing effect

Therefore, there is an urgent need in the art for a device that can automatically prepare foam stock solution from foam powder at the scene of a fire, so as to meet the needs of various fire extinguishers for the amount of foam stock solution, and can fully exert the foam fire extinguishing effect, but so far no related technology or product report
