Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water treatment equipment, specifically relates to a self-priming vacuum tank capable of improving vacuum degree. BACKGROUND

[0002] The self-priming vacuum tank is a device that can automatically extract air and create a vacuum environment. It uses internal mechanical devices (such as pumps or compressors) to extract air, achieving low pressure or vacuum state, commonly used for storage and transportation of liquids, gases or particles. Compared with traditional vacuum pump systems, the self-priming vacuum tank has high self-priming capacity and can automatically complete the air extraction process without external assistance, commonly used for material storage and processing in food, chemical, pharmaceutical and other fields.

[0003] The vacuum degree refers to the difference between the pressure inside the container and the external atmospheric pressure, usually expressed in absolute pressure, the higher the vacuum degree, the lower the air pressure. The self-priming vacuum tank achieves the required vacuum degree by extracting air, thereby creating a low pressure environment. In the self-priming vacuum tank, the increase of vacuum degree means that the air in the tank is extracted more effectively, creating a lower pressure, and a higher vacuum degree can prolong the shelf life of food, reduce chemical reactions, avoid gas or liquid evaporation, and optimize the performance of the equipment, ensuring stability and safety during storage and processing.

[0004] Patent CN213298303U discloses a vacuum self-priming tank, which is arranged before a centrifugal pump and includes a tank body and a liquid guide pipe in the tank body.

[0005] However, the vacuum self-priming tank in the above technical solution will slowly scale the inner wall of the vacuum self-priming tank after long-term use. With the passage of time, the accumulated scale material inside the vacuum tank will gradually accumulate on the inner wall, forming a layer of scale that hinders gas flow. These deposits will increase the resistance to gas flow, reducing the air extraction efficiency and affecting the performance of the vacuum system; due to scaling, the air extraction effect of the pump is weakened, the vacuum degree is difficult to reach the design requirement, and finally the pressure in the tank is difficult to reduce to the required low level, and the maximum vacuum degree value is reduced.
