Abstract

Technical Field
[0001] The utility model belongs to the technical field of sodium nitrate, and more specifically, particularly relates to a precise proportioning device for the production and processing of sodium nitrate. Background Art
[0002] Sodium nitrate has a wide range of uses. It can be used as a flux, oxidant and raw material for preparing enamel powder in the enamel industry. It can be used as a decolorant, defoamer, clarifier and oxidizing flux for various glasses and products in the glass industry. It can be used as a decolorant for molten caustic soda and used to make other nitrates in the inorganic industry. It can be used as a coloring agent in meat processing in the food industry to prevent meat from spoiling and can also serve as a seasoning. It can be used as a quick-acting fertilizer suitable for acidic soils in the fertilizer industry.
[0003] Based on the above, the inventors found that there are the following problems: in the existing sodium nitrate production process, pure alkali solution and conversion solution need to be added until the pH value reaches the requirement, but most of them cannot be added quantitatively according to the proportion, and the staff need to add it manually, which may cause a large mixing error, and nitric oxide gas will be generated during the mixing of raw materials. Nitric oxide gas reacts with alkali solution to generate sodium nitrite, and the content of sodium nitrite directly affects the quality of sodium nitrate solution. This will cause harm to the physical and mental health of the staff.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a precise proportioning device for sodium nitrate production and processing is provided, in order to achieve a purpose with greater practical value. Utility Model Content

The operation steps are very simple, which effectively reduces the error rate and indirectly brings convenience to the staff. There is no need for the staff to add manually, and this design greatly increases the practicality.
[0016] Through the design of the SV mixer, the conversion liquid and the pure alkali solution can be fully mixed, making the mixing more uniform, which indirectly improves the mixing efficiency.
