Anti-freezing and heat-insulating fire-fighting liquid tank

Abstract

The invention relates to an anti-freezing and heat-insulating fire-fighting liquid tank. A layer of framework is jointed with the outer wall of a tank body of the fire-fighting liquid tank; a rigid foam polyurethane thermal-insulation coating is filled in the framework; an aluminum plate or steel plate protective layer is adhered to the outer wall of the framework; a plurality of groups of snakelike metal radiating pipes are paved in series or in parallel on the inner wall of the tank body of the liquid tank; both ends of the metal radiating pipes are communicated with a water outlet and a water return opening of a fuel heater arranged outside the tank body of the liquid tank respectively; a water pump is arranged in the fuel heater; and a set of stirrer is arranged in the tank body of the liquid tank. The anti-freezing and heat-insulating fire-fighting liquid tank has the advantages that a heat-insulating layer is in complete fit with the tank body so as to insolate heat exchange between the fire-fighting liquid tank and the outside world to a maximum degree and keep the temperature of the fire-fighting liquid in the tank; the water pump on the fuel heater drives hot water in theradiating pipes to flow circularly, so the fire-fighting liquid in the tank is heated quickly; and the operation of the stirrer enables the water in the tank to keeps a flowing state, so that the possibility of icing of the water in the tank is reduced greatly.

Description

technical field [0001] The invention relates to an antifreeze heat preservation fire fighting liquid tank. Background technique [0002] In cold areas, the outdoor temperature in winter is often -10°C to -20°C below zero, sometimes even -30°C to -40°C below zero. Such a climate environment gives local firefighting vehicles, especially water tank foam fire trucks, a long-term Long-term field duty missions or long-duration field firefighting missions pose considerable difficulties. It often happens that the fire-fighting liquid in the fire-fighting liquid tank freezes, or the fire-fighting water pump freezes and cracks during fire extinguishing, the valve of the water pump system freezes and cannot be opened and closed, and the water hose interface freezes and cannot be connected to the water hose, etc., causing firefighters to fail to work normally. , causing insurmountable difficulties to the smooth completion of firefighting tasks, and causing huge losses to the safety of l...
