Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide raw material technology, specifically to a pesticide raw material pretreatment and purification device. Background Technology
[0002] Pesticide production is a complex and delicate process, and the pretreatment of raw materials is a crucial step. Pulverization pretreatment can significantly increase the surface area of pesticide raw materials, thereby increasing their contact area with solvents or other reactants. This increased surface area not only facilitates the full conduct of chemical reactions but also improves the uniformity and stability of pesticide products. Furthermore, pulverized raw materials are easier to dissolve and disperse, which helps subsequent processes proceed smoothly.
[0003] For example, a pesticide residue detection sample pretreatment device (Announcement No.: CN221260582U) includes a housing with a feed hopper at the top and a crushing device inside the feed hopper. The housing contains a first chamber and a second chamber arranged vertically and communicating with each other. A grinding cylinder is rotatably connected to the inner cavity of the housing, located between the first and second chambers. The surface of the grinding cylinder has uniformly distributed sieve holes. First extrusion rollers located on both sides of the grinding cylinder are rotatably connected to the first chamber. The grinding cylinder is connected to a first rotating shaft that rotates through the housing and is driven by a drive mechanism. A discharge port communicating with the second chamber is located at the bottom of the housing. This pesticide residue detection sample pretreatment device crushes the sample to be tested using the crushing device, and then the grinding cylinder and extrusion rollers work together to press the crushed sample, ensuring thorough sample crushing. The grinding cylinder also performs solid-liquid separation on the crushed sample.
[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the aforementioned equipment, through the cooperation of a grinding cylinder and two sets of first extrusion rollers to press and crush the sample, can ensure the crushing of the sample. However, some of the crushed sample is likely to remain between the first extrusion roller and the first cavity, affecting the crushing efficiency. Regular cleaning of the residue is required, which increases downtime and maintenance costs, and also increases the risk of contamination. The residue may contain incompletely crushed samples or impurities, which may deteriorate or cause contamination due to prolonged retention. In the next use, the residue may mix into the new sample, affecting the product quality. Therefore, we need to propose a pesticide raw material pretreatment and purification device.
