Purification device for veterinary drug intermediate production

Abstract

The invention discloses a purification device for veterinary drug intermediate production. The purification device comprises an installation plate, a first screening unit, a moving unit, a screening barrel and a second screening unit, wherein the right end of the upper surface of the installation plate is fixed with an installation block, the left end of the upper surface of the installation plateis fixed with a storage box, an opening is formed in the upper side of the storage box, the first screening unit comprises fixing plates, screening boxes, screening holes and a connecting plate, twofixing plates are provided, the two fixing plates are correspondingly fixed in the storage box, sliding grooves are formed in the sides of the fixing plates, the screening boxes are slidingly connected in the two sliding grooves, openings are formed in the upper sides of the screening boxes, uniformly distributed screening holes are formed in the lower sides of the screening boxes, so that drug raw materials can be purified efficiently, manual screening can be avoided, and the workload of workers is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of purification devices, in particular to a purification device for the production of veterinary drug intermediates. Background technique [0002] Veterinary drug intermediates are some chemical raw materials or chemical products used in the synthetic process of veterinary drugs. Such chemical products do not require a drug production license and can be produced in ordinary chemical factories. As long as they reach a certain level, they can be used For the synthesis of veterinary drugs, in the process of synthesizing veterinary drug intermediates, it is often necessary to separate and purify the synthesized or extracted compounds to obtain a single compound or a class of compounds with the same structure as the mother nucleus. The drug has extremely high requirements on the purity of the drug during the production process. High, so it is necessary to remove the impurities in the raw materials of the drug. Th...

[0002] Veterinary drug intermediates are some chemical raw materials or chemical products used in the synthetic process of veterinary drugs. Such chemical products do not require a drug production license and can be produced in ordinary chemical factories. As long as they reach a certain level, they can be used For the synthesis of veterinary drugs, in the process of synthesizing veterinary drug intermediates, it is often necessary to separate and purify the synthesized or extracted compounds to obtain a single compound or a class of compounds with the same structure as the mother nucleus. The drug has extremely high requirements on the purity of the drug during the production process. High, so it is necessary to remove the impurities in the raw materials of the drug. The traditional separation method mostly uses artificial filter screens for separation. Using this method to filter is time-consuming and laborious, and the effect is extremely poor
