Description

Technical Field

[0001] This utility model relates to the field of chemical engineering technology, and in particular to a refining and crystallizing apparatus for fipronil. Background Technology

[0002] With the modernization of agriculture, the demand for crop pest and disease control is constantly increasing. As an excellent insecticide, fipronil has a large market demand. To meet this demand, large-scale production of high-quality fipronil products is required. This places higher demands on the refining and crystallization process of fipronil, requiring the development of efficient and stable refining and crystallization equipment to improve production efficiency and product quality. The quality standards for pesticide products are becoming increasingly stringent. Crude fipronil often contains impurities, which can affect its insecticidal effect and environmental safety. Through refining and crystallization equipment, impurities can be effectively removed, improving the purity of fipronil and ensuring it meets relevant quality standards, thus guaranteeing the product's competitiveness in the market.

[0003] A search revealed Chinese Patent Publication No. CN220918198U, which discloses a crystallization device belonging to the technical field of crystallization equipment. The device includes a processing vessel, with a feed pipe installed at the top and a discharge pipe installed at the bottom. Both the feed and discharge pipes are equipped with solenoid valves. The outer surface of the processing vessel has a heating structure for circulating heating, and a cleaning structure for cleaning and stirring. A ventilation hole is located at the top of the processing vessel. The heating structure includes a load-bearing plate fixedly connected to the outer surface of the processing vessel. This crystallization device, through the processing vessel, feed pipe, and discharge pipe...
