Description

Technical Field

[0001] The utility model relates to the technical field of sodium heparin production, in particular to a vacuum drying box based on sodium heparin production. Background Art

[0002] Heparin Sodium Heparin Sodium is a mucopolysaccharide sulfate anticoagulant. Heparin Sodium is the sodium salt of aminoglucan sulfate extracted from the intestinal mucosa of pigs or cattle, and belongs to the mucopolysaccharide substance. Recent studies have shown that heparin sodium also has the effect of lowering blood lipids. Heparin Sodium is a white or gray-brown amorphous powder, odorless, tasteless, and hygroscopic. It is easily soluble in water, and insoluble in organic solvents such as ethanol, ether, acetone and benzene.

[0003] When sodium heparin is dried, due to its amorphous and hygroscopic properties, vacuum equipment is mostly used to avoid reactions during drying. A stirring device is generally provided in the equipment to achieve the purpose of drying. However, due to the hygroscopicity of sodium heparin, even if the boiling point requirement of 50°C to 60°C is reached after it is accumulated in the original vacuum equipment, a lot of water vapor will remain and adsorb with sodium heparin to form lumps or large particles, resulting in incomplete and uniform drying, poor effect, and easy formation of particulate matter, which affects the refining effect. At the same time, the existing equipment disclosed does not have a drying box that can complete continuous production.

[0004] A sodium heparin low-temperature vacuum drying oven is proposed in the patent document with the publication number CN215113768U. The device includes a box body and an upper cover. The upper cover is provided with a vacuum pipe and a pressure relief pipe. The lower part of the box body is connected to a storage bin. A discharge valve is installed at the bottom of the storage bin. A plurality of conveyor belts are arranged in the box body. The conveyor belts are arranged in layers and staggered. A material spreading roller is arranged above the conveyor belt. A material guide plate is arranged at the starting end of the conveyor belt. The upper end of the material guide plate is fixed on the inner wall of the box body. A feed hopper is arranged in the box body above the starting end of the top conveyor belt. The feed hopper is funnel-shaped, and a material discharge mechanism is arranged at the bottom of the feed hopper. The sodium heparin low-temperature vacuum drying oven provided by the utility model is provided with a material discharge hopper inside the box body, and a material discharge mechanism is provided inside the hopper. The material discharge mechanism can discharge materials continuously and quantitatively by rotating, and the materials falling onto the conveyor belt can be flattened with the cooperation of the material spreading roller. The material discharge hopper is arranged in the box body, which can meet the vacuum environment in the box body during continuous production.

[0005] However, during the production of sodium heparin, it is not easy for the device to be fully heated, which can easily affect its production efficiency to a certain extent.
