[0002] The full name of pharmaceutical intermediates is medical community, which refers to a medical system formed by integrating district and township medical and health resources with district-level hospitals as the leader. Ethyl dicyanopropionate in pharmaceutical intermediates belongs to ester compounds with molecular formula C7H8N2O2 and molecular weight 152.15. It is a colorless and transparent liquid at room temperature and is insoluble in water, but soluble in ether and ethyl acetate. It is mainly used as a pesticide intermediate, such as an intermediate for the insecticide fipronil. Ethyl dicyanopropionate needs to be purified during the production process, which requires a purification device. The purification device is a key equipment used to separate impurities from the mixture to improve the purity and quality of the mixture. In the chemical, pharmaceutical and food industries, purification devices have been widely used to meet product quality requirements.

[0003] After searching, a purification device with publication number CN219663106U is found, which specifically discloses a purification device, including a box body, a stirring barrel arranged at the upper end of the box body, and a filter box arranged at the lower end of the box body, both sides of the outside of the stirring barrel are fixedly installed with the inner walls of both sides of the box body through fixing blocks, the top of the box body is connected with a feeding pipe connected with the inside of the stirring barrel, a motor is fixedly installed with a bracket on the top of the box body, and the output end of the motor is driven and connected with a stirring rod. During the use of the utility model, the purification device can effectively purify urea, avoiding the long-term purification and filtering operation of urea by the device, which may cause the impurities on the filter plate to accumulate and easily clog the filter holes of the filter plate and affect the subsequent urea purification effect, and personnel need to disassemble the device to clean the internal filter plate, resulting in more time spent on cleaning and increasing the burden on personnel, thereby reducing the burden on personnel and improving the purification effect and practicality of the device.

[0004] In the above patent, the urea purification operation can be effectively performed only by means of a box, a stirring barrel, a filter plate, a feed pipe and a stirring rod, thereby avoiding the long-term purification and filtering operation of the device for urea. Impurities on the filter plate may accumulate and easily clog the filter holes of the filter plate, thereby affecting the effect of subsequent urea purification. However, when the purification device purifies ethyl dicyanopropionate, due to different purification requirements, some need to mix ethyl dicyanopropionate with a purification agent and water, while others need to isolate and purify ethyl dicyanopropionate from heated water. If ethyl dicyanopropionate is directly poured in, the purification work of ethyl dicyanopropionate cannot be fully completed, which will cause the purification of ethyl dicyanopropionate to fail, thereby wasting raw materials, and it is not convenient for the device to purify ethyl dicyanopropionate in batches, thereby delaying the overall work efficiency.
