Intermediate decolorization core assembly used in steroid drug production process

Abstract

The invention provides an intermediate decolorization core assembly used in a steroid drug production process, and relates to the technical field of steroid drug production, the intermediate decolorization core assembly sequentially comprises an activated carbon filtration cleaning device, an activated carbon activation drying device and an activated carbon crushing device; a filtering feeding hole is formed above the activated carbon filtering and cleaning device, a filtering carbon outlet and a filtering liquid outlet pipe are arranged under the activated carbon filtering and cleaning device, and a filtering mechanism is arranged inside the device; a water inlet is formed in the upper part of the tank body, and a blow-off pipe is arranged below the tank body; a drying carbon inlet is formed above the activated carbon activating and drying device, and a drying carbon outlet is formed below the activated carbon activating and drying device and is used for preheating, introducing steamto activate, heating and drying the activated carbon discharged from the filtering carbon outlet; the upper part of the activated carbon crushing device is connected with the dry carbon outlet, and the lower crushing carbon outlet is communicated with the reaction tank feeding hole through a conveying pipeline. The assembly is used for separating activated carbon from an intermediate, and meanwhile, the activated carbon is quickly activated and dried, so that the decolorized activated carbon is conveniently recycled.

Description

technical field [0001] The invention relates to the technical field of steroid drug production, in particular to an intermediate decolorization core component used in the process of producing steroid drug. Background technique [0002] Steroid drugs are mainly corticosteroid drugs and sex hormone drugs, which occupy an important position in the chemical drug system. The discovery and successful synthesis of steroid drugs are known as one of the two major advances in the pharmaceutical industry in the 20th century. Steroidal drugs play a very important role in regulating the body, have strong anti-infection, anti-allergy, anti-virus and anti-shock pharmacological effects, can improve protein metabolism, restore and enhance physical strength, diuretic and blood pressure, and are widely used in the treatment of Rheumatoid arthritis, bronchial asthma, eczema and other skin diseases, anaphylactic shock, prostatitis, Addison's and other endocrine diseases can also be used for cont...

Problems solved by technology

The traditional decolorization process currently used is to put these intermediates, decolorizers, and activated carbon into the reactor, and after a period of reaction, filter and separate the activated carbon. However, in this production process, the manual process The operation is usually cumbersome and not suitable for the high-efficiency and high-quality production requirements of the factory. Therefore, the applicant has developed and designed a series of decolorization components and a complete non-stop production decolorization system for this decolorization problem.
