Description

2, 4-Dichloropyrimidine condensation section device Technical Field The utility model relates to the technical field of high vacuum distillation equipment, in particular to a 2, 4-dichloropyrimidine condensing and slicing device. Background 2, 4-Dichloropyrimidine, CAS 3934-20-1, is an important organic synthesis intermediate, is often used as a building block for Suzuki coupling, alkylation and other reactions, is widely applied to the fields of preparing pesticides, dyes, photosensitive substances, medicines and other organic compounds, has a melting point of 58-61 ℃, so that slicing and packaging are sometimes carried out by a slicing machine in chemical production, the molten liquid is melted, then cooled and solidified into solid by a roller, the solid is uniformly attached to the roller, the roller continuously rotates, and the chemical attached to the roller is scraped by a blade through a blade, and then packaged by a hopper. Patent CN202323113026.0 discloses a 2, 4-dichloro-5-fluoropyrimidine slicer, 2, 4-dichloro-5-fluoropyrimidine is 2, 4-dichloropyrimidine with fluorine atoms substituted on 5-carbon of pyrimidine, the patent discharges the rest gas by arranging an air inlet pipe to prevent the material from reacting with the rest gas, improves the purity of the finished product, and is provided with a distributing plate to enable continuous production of the material and increase the production rate, but the problem still exists when the slicer is applied to the condensation slicing of 2, 4-dichloropyrimidine that the situation of incomplete melting may exist, such as partial solid material is carried by liquid molten material, uneven slicing may be caused, uneven condensation may also occur when the partial molten material is condensed, such as slicing is not solidified, condensed material is adhered on a blade, and the problems of slicing and uneven slicing are caused. Therefore, further research on the condensation slicing process of 2, 4-dichloropyrimidine is urgently needed, a brand new condensation slicing device for 2, 4-dichloropyrimidine is provided, the melting and condensation processes of materials are guaranteed to be uniform, the condensation slicing efficiency is improved, and the quality of sliced products is improved. Disclosure of utility model In order to solve the problems, the utility model provides the 2, 4-dichloropyrimidine condensing and slicing device, and the special feeding device, the condensing device and the slicing device are arranged, so that the melting process is more uniform, the slicing process is more stable and uniform, and the quality of sliced products and the slicing production efficiency are obviously improved. In one aspect, the utility model provides a 2, 4-dichloropyrimidine condensation slicing device, which comprises a feeding device, a condensation device and a slicing device, wherein the feeding device comprises a heater and a feeding hopper, the heater is arranged on the outer side of the feeding hopper, the condensation device comprises a crawler belt and an air cooler, one end of the crawler belt is arranged below the feeding hopper, an air inlet of the air cooler faces the crawler belt, and the slicing device comprises a scraper, and the scraper is arranged below the other end of the crawler belt.
