[0002] Sodium hydroxide, commonly known as caustic soda, caustic soda and caustic soda, is a strong alkali with strong corrosiveness. It is generally in the form of flakes or blocks, easily soluble in water to form an alkaline solution, and is also deliquescent. Industrial products contain a small amount of sodium chloride and sodium carbonate, and are white opaque crystals. Caustic soda is one of the essential chemicals in chemical laboratories and is also one of the common chemical products. When producing sodium hydroxide, crude salt is required as a raw material for preparation. Therefore, the dissolution of crude salt is the premise and basis for the preparation of caustic soda. However, when existing salt-making equipment dissolves crude salt, the crude salt has large particles, resulting in a slow dissolution rate of the crude salt. Secondly, since most existing salt-making equipment does not have the function of preheating the crude salt, the dissolution efficiency of the crude salt is further reduced, which is not conducive to use. Therefore, a sodium hydroxide solution feeding device is proposed. Utility Model Content
