Description

Technical Field

[0001] This application relates to the technical field of salting out, and in particular to a salting out apparatus for chemical production. Background Technology

[0002] Salting out is a method of nitrate extraction that uses the addition of salts to reduce the solubility of nitrates in a solution, thereby achieving the separation and purification of nitrates. This method is commonly used in the chemical industry to extract nitrates from complex mixtures, such as potassium nitrate and sodium nitrate.

[0003] Based on the properties and solubility curve of nitrates, select appropriate salts and adjust the pH of the solution to a suitable range to facilitate nitrate precipitation. After adding the salts, continue stirring for a period of time to ensure complete dissolution. Then, let it stand for a period of time to allow the nitrates to precipitate. Use centrifugation or filtration to separate the precipitated nitrates from the supernatant. Wash the precipitate with an appropriate solvent to remove residual salts and other impurities.

[0004] The inventors have found the following drawbacks in the existing related technologies: it is difficult to achieve quantitative salt addition in the tank. If quantitative salt addition cannot be achieved, the purity of the final product may not meet the requirements, because the amount of salt added directly affects the selectivity and purity of the precipitation, and more monitoring and adjustment are required, which increases the difficulty of operation and the risk of error.

The other end of the connecting pipe 207 is connected to the bottom of the tank 10. By manually turning the valve 202, the salt slurry inside the tank 11 flows into the material box 203. Then, by starting the metering pump 204, the salt slurry inside the material box 203 is pumped into the tank 10, realizing automatic feeding, avoiding manual feeding and improving convenience.

[0026] Please see Figure 2A discharge pipe 208 is fixedly connected to one side of the bottom of the tank 10. A discharge valve 209 is fixedly connected to the bottom end of the discharge pipe 208. The processed material inside the tank 10 is discharged by manually turning the discharge valve 209 to avoid difficulty in discharging the material, spilling it on the ground and causing pollution.

[0027] Please see Figure 4 The quantitative component 21 includes an inlet pipe 211 connected to the outer wall of the tank 10. An inlet box 212 is fixedly connected to the top of the inlet pipe 211.
