Description

Technical Field

[0001] The utility model relates to the technical field of phosphoric acid production, in particular to a phosphoric acid production device. Background Art

[0002] Phosphoric acid, also known as orthophosphoric acid, is a common inorganic acid. It is a medium-strong acid that is not volatile, not easy to decompose, and has almost no oxidizing properties. It is mainly used in the pharmaceutical, food, fertilizer and other industries. It can also be used as a chemical reagent. Phosphoric acid is usually prepared by a wet process or a thermal process. The former has a simpler process difficulty, but the purity of the phosphoric acid produced is lower and it is widely used in industry. The latter has a more complicated process difficulty, but the purity of the phosphoric acid produced is higher and it is suitable for use in occasions with higher purity requirements.

The utility model immerses the storage tank with inorganic acid and starts the motor inside the sealing box. At this time, the motor can drive the extension shaft to rotate, and at the same time drive the storage tank below to rotate. At this time, the inorganic acid enters the interior of the storage tank through the filter holes on the surface of the storage tank and fully contacts the phosphate ore inside the storage tank. The two react with each other to generate phosphoric acid inside the reaction tank, and the generated by-products remain in the storage tank. After the reaction is completed, the phosphoric acid can be released by opening the discharge valve to wait for subsequent purification, thereby improving the reaction sufficiency and the reaction efficiency. The above-mentioned storage tank is fixedly arranged and inconvenient to disassemble. It is inconvenient to take out the by-products inside the storage tank, which is labor-consuming and time-consuming. Therefore, a phosphoric acid production device is proposed to solve the above problems. Utility Model Content
