Fully sealed plate vane-type purification filter

Abstract

The invention relates to a filtering and collection unit of a pharmaceutical terminal for semi-finished products. The filtering and collection unit is of a fully sealed plate vane-type purification filter. The purification filter comprises a tank and an upper cover which are fixedly connected by flange bolts; a feed tube is arranged on top of the tank and a discharge tube is arranged at the bottom of the tank; the purification filter is characterized in that: a sieve plate is arranged slantwise at a distance above the bottom of the tank, and a collection tube is arranged on a side wall of the tank and on an upper surface of a lower end of the filter sieve plate; a collection and discharge tube spanning the tank is arranged above the filter sieve plate and has one end extending outside the tank and externally connected with the discharge tube; a plurality of plate-shaped filter mantles are arranged in parallel above the collection and discharge tube, and all plate-shaped filter mantles are provided with discharge openings at the bottoms for communicating with the collection and discharge tube. The purification filter helps solve problems of severe work environment, insalubrity, effect on quality of products and low production efficiency of in the existing manual filtering and collecting with cloth bags, and is especially suitable for enzymatic hydrolyzate filtration or resin collection during production of sodium heparin products.

Description

(1) Technical field: [0001] The invention relates to filtering and collecting equipment for semi-finished products of biopharmaceuticals, which is a fully sealed leaf type purification filter. (two) background technology: [0002] In the production of biopharmaceuticals, such as the terminal of heparin sodium production, the process of filtration and collection is usually carried out. The traditional method is to use artificial bag filtration and collection. Because this kind of product has a strong peculiar smell, it is usually necessary to build a certain height in the work place. Although it can reduce the peculiar smell around the working place, the exhaust gas through the chimney has an impact on the surrounding environment. At the same time, the labor intensity of the specific operators and the environmental impact cannot be improved. On the other hand, the manual operation does not meet the hygienic requirements, which affects the guarantee of product quality, and the...
