Device for automatically preparing foam stock solution through foam powder

Abstract

The invention discloses a device for automatically preparing a foam stock solution through foam powder. The device comprises a mixing barrel, a foam stock solution storage tank, a foam powder storage tank and a driving platform used for driving the foam powder storage tank to rise, fall and rotate, wherein a powder adding hole is formed in the top of the mixing barrel; a stirrer is arranged in the mixing barrel; a water inlet hole is formed in the upper part of the mixing barrel; a foam stock solution outlet is formed in the lower part of the mixing barrel; the foam stock solution outlet communicates with the foam stock solution storage tank; the foam powder storage tank comprises a tank body; the peripheral wall of the tank body is divided into an airtight part and an open part from top to bottom; a fixed sleeve is arranged in the position, on the periphery of the airtight part, of the tank body; a movable sleeve is arranged in the position, on the periphery of the open part, of the tank body; the fixed sleeve and the movable sleeve form an up-down telescopic structure; and the size of the inner diameter of the powder adding hole is between the size of the outer diameter of the tank body and the size of the outer diameter of the movable sleeve. According to the device, the foam stock solution can be automatically prepared through foam powder at a 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
