Foam recovery device and foam fire fighting truck equipped with foam recovery device

Abstract

The invention provides a foam recovery device and a foam fire fighting truck equipped with the foam recovery device, and belongs to the technical field of fire fighting equipment. The foam recovery device comprises a foam driving-out plug pipe, a foam driving-out travelling plug, a foam driving-out plug pipe first joint, a foam driving-out plug pipe second joint and a pressure air introduction mechanism, wherein the foam driving-out plug pipe consists of a foam driving-out travelling plug cavity penetrating through one end of the foam driving-out plug pipe to the other end; the foam driving-out travelling plug is arranged in the foam driving-out travelling plug cavity; the foam driving-out plug pipe first joint is matched and connected with one end of the foam driving-out plug pipe, and the foam driving-out plug pipe second joint is matched and connected with the other end of the foam driving-out plug pipe; and the pressure air introduction mechanism is matched and connected with the lateral part of the foam driving-out plug pipe corresponding to the position between the end face of one end, facing the foam driving-out plug pipe first joint, of the foam driving-out travelling plugand the foam driving-out plug pipe first joint and communicates with the foam driving-out travelling plug cavity, and the pressure air introduction mechanism is further in pipeline connection with a vehicle-mounted pressure air generator of the foam fire fighting truck. The operation intensity is lowered, and foam waste is avoided; and the requirement of firefighters to collect residual foam of afoam conveying belt after work is met.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting facilities, in particular to a foam recovery device, and also relates to a foam fire truck equipped with the foam recovery device. Background technique [0002] The aforementioned foam is mainly composed of fluorocarbon surfactants, fluorine-free surfactants and additives to improve foam performance such as foam stabilizers, antifreeze agents, thickeners, auxiliary agents and water, for such as oil fields, oil refineries, oil depots, It has an ideal fire extinguishing effect in refueling stations, chemical and pharmaceutical enterprises, aircraft and their hangars, etc. [0003] The aforementioned foam fire trucks mainly include two categories: one is a foam fire truck with main combat properties, such as CN205108842U (a foam fire truck), CN206631041U (a main force foam fire truck with a piercing arm) and CN208771810A (a foam fire truck) and so on; the second is a foam fire truck with a bac...
