Abstract

An oxaliplatin wet product drying device comprises a sealed casing; a viewing window and an opening-closing door body are arranged on the casing; the device is characterized in that a vacuum-pumping pipeline and an explosion-proof electric pipeline are arranged in the interior space of the casing; at least one dryer is arranged in the interior space of the casing; at least one pumping hole is formed in the top of the casing and is connected a negative pressure device on the outer side. According to the invention, a vacuum drying box is arranged in a sealed space, and a small amount of escaping material is pumped away, so that pollution to the working space is reduced; the explosion-proof electric pipeline is used so as to effectively prevent the arc phenomenon, and then the working process is safer; meanwhile, pumped tail gas is treated in an adsorption manner, so as not to cause environment pollution.

Description

technical field

[0001] The invention relates to the technical field of drying of oxaliplatin production, in particular to an oxaliplatin wet product drying device. Background technique

[0002] The refining method of the crude oxaliplatin is recrystallization with purified water, washing with an organic solvent such as ethanol and suction filtration to obtain a wet product, and then drying to obtain the refined oxaliplatin. At present, a vacuum drying oven is used in the drying process. The method of use is usually to place the vacuum drying oven in the workshop, and then place the wet product to be dried in the drying oven. After the power is turned on, the wet product can be dried. Drying operation, the problem in this process is that although the drying box has good sealing performance, a small amount of oxaliplatin and organic solvents will still escape during the process of picking and placing materials and drying , cause workshop pollution, oxaliplatin causes personne...
