Background In the development process of the phosphorus chemical industry, the safe storage and quality assurance of phosphorus raw materials are key technologies of the industry. The phosphorus raw materials (such as yellow phosphorus, red phosphorus and the like) have high chemical activity, are easy to generate oxidation reaction with oxygen in air in the storage process, even induce spontaneous combustion, and meanwhile, the chemical activity is aggravated by temperature fluctuation or the physical state change (such as melting and sublimation) is caused, so that the anti-oxidation and heat insulation control is the core of the storage safety of the phosphorus raw materials. At present, when the phosphorus raw material is stored, a phosphorus raw material storage tank is needed, the phosphorus raw material storage tank has sealing and heat insulation effects, and oxygen and temperature can be isolated by sealing the phosphorus raw material in the phosphorus raw material storage tank. In the prior art, the traditional phosphorus raw material storage tank is generally insulated by only relying on the thermal resistance of the tank body material, when the fluctuation of the external environment temperature is large, heat is easily conducted to the inside through the tank body, so that the temperature in the tank is unstable, when the heat is generated due to chemical reaction or physical change in the storage process of the phosphorus raw material, the temperature of the phosphorus raw material in the tank cannot be efficiently reduced, potential safety hazards exist, and the traditional phosphorus raw material storage tank is mostly isolated by only relying on the sealed tank body, but the time is long, when the storage environment in the tank is required to be filled with inert gas (such as argon) for anti-oxidation protection, the efficient gas replacement is lacking, the stable inert gas atmosphere is difficult to form, and the anti-oxidation effect can be greatly reduced.
