AI Technical Summary
Traditional stirred tank drying methods cause barium sulfate crystals to accumulate inside the stirred tank, occupying space, hindering heat transfer, resulting in low drying efficiency and uneven crystal drying, which affects product quality and consistency.
The design employs a combination of annular filter, hollow ring, stirring assembly, heating assembly, and reflux assembly. By filtering with the annular filter, heating and leveling with the hollow ring, separating with the stirring assembly, and reheating with the reflux assembly, barium sulfate solution can be rapidly dried and uniformly heated.

TECHNICAL FIELD
[0001] The utility model relates to barium sulfate processing technical field, concretely relates to a barium sulfate solution drying treatment equipment. BACKGROUND
[0002] Barium sulfate is an important chemical raw material, and is widely used in paint, plastic, rubber, papermaking, pharmaceutical and other industries. In the production process of barium sulfate, the drying of barium sulfate solution is a key step, and the purpose is to evaporate the water in the solution by heating and stirring, so as to form barium sulfate crystals. The traditional barium sulfate solution drying process usually adopts the stirring tank, and the specific process is as follows: first, the staff puts the barium sulfate solution to be dried into the stirring tank, and then starts the stirring motor in the stirring tank, and the stirring motor is used for stirring the barium sulfate solution, and the solution is heated in the stirring process, so that the water in the solution is gradually evaporated, and finally the barium sulfate crystals are formed. After drying, the discharge valve of the stirring tank is opened, and the barium sulfate crystals are discharged.
[0003] However, the traditional stirring tank drying method has the following technical defects in practical application. First, due to the design characteristics of the stirring tank, the barium sulfate solution needs to be completely formed into crystals before the discharge valve is opened for discharge in the drying process. This operation mode causes the barium sulfate crystals formed first to be retained in the stirring tank, and with the progress of the drying process, more and more barium sulfate crystals are accumulated in the stirring tank. This accumulation not only occupies the effective space of the stirring tank, but also hinders the heating and drying process of the barium sulfate solution in the lower part of the stirring tank. Specifically, the accumulated barium sulfate crystals block the heat transfer, making it difficult for the solution in the lower part of the stirring tank to be heated sufficiently, thereby reducing the overall drying efficiency. In addition, due to the differences in temperature and stirring effect in different regions of the stirring tank, the drying degree of barium sulfate crystals is uneven, part of the crystals may be over-dried, and another part of the crystals may not be completely dried, affecting the quality and consistency of the product.
