Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of paclobutrazol production, in particular to a pretreatment device for paclobutrazol production convenient to clean and maintain. BACKGROUND

[0002] In the production process of paclobutrazol, the pretreatment link plays a crucial role. The quality of pretreatment directly determines the purity, stability and production efficiency of the final product. Specifically, the pretreatment link includes a series of steps such as selection, cleaning and crushing of raw materials. Fine operation of these steps can ensure the purity and uniformity of the raw materials, thereby providing a good foundation for subsequent chemical reactions. If the pretreatment link is not handled properly, it may cause impurities to remain, affecting the purity of the product and thus affecting its stability and use effect. In addition, the efficiency of the pretreatment link directly affects the rhythm of the entire production process. Efficient pretreatment can shorten the production cycle and improve production efficiency. Therefore, optimizing the pretreatment link and ensuring its quality are of great significance to the production of paclobutrazol.

[0003] Traditional paclobutrazol production pretreatment devices often have many inconveniences. On the one hand, the stirring equipment and the cleaning equipment are usually independent and fixedly installed. When the pretreatment container needs to be cleaned, a lot of manpower and time are needed for complex disassembly and installation work. This not only causes the interruption of the production process, reducing the overall production efficiency, but also increases the risk of damage to the equipment parts due to frequent manual operation, increasing the equipment maintenance cost. On the other hand, in the stirring process of the traditional pretreatment device, the material is easy to adhere to the inner wall of the container, which is difficult to completely remove. The residual material not only affects the quality of the next batch of products, but also may cause deterioration in the container, corrosion of the container wall and other problems, shortening the service life of the equipment. At the same time, due to the lack of effective cleaning mechanism and convenient switching mode, the cleaning of the pretreatment container is often not thorough enough to meet the strict production hygiene standards and quality requirements.
