[0002] In the manufacturing of traditional Chinese medicine, health foods, functional foods, and cosmetics, mixing tanks are commonly used individual pieces of equipment for different product dosage forms. Older mixing tanks cannot operate at low temperatures and negative pressure, nor can they handle materials in a closed system. This makes it difficult to control the temperature optimally, affecting product quality and causing material loss. Manufacturers typically cool the materials before mixing, which requires a large floor space and incurs high costs. Utility Model Content

[0003] This invention aims to solve the problems of traditional mixing tanks being unable to operate at low temperatures and negative pressure and transport materials in a closed system. It provides an energy-saving and efficient vacuum water-cooled liquid mixing tank, which is a commonly used device for mixing and stirring high-temperature liquid materials under vacuum cooling conditions into low-temperature liquids and transporting them to other equipment containers.

[0004] To achieve the aforementioned objectives, this utility model provides an energy-efficient vacuum water-cooled liquid mixing tank, comprising a mixing tank body, a cooling circulation system, and a water ring vacuum pump. The mixing tank body is completely sealed internally, with a stirring paddle located in the middle. The stirring paddle is connected to a mixing and stirring motor mounted on the upper side of the vacuum water-cooled liquid mixing tank. The sidewall of the mixing tank body adopts a sandwich structure, with a cooling circulation system installed in the intermediate sandwich between the inner and outer steel plates. The cooling circulation system is a bottom-inlet, top-return circulating water pipeline, with a cooling circulating water inlet at the lower end connected to a workshop cold water tank and a cooling circulating water return outlet at the upper end. The upper end of the vacuum water-cooled liquid mixing tank has a vacuum inlet, which is connected to the water ring vacuum pump via a vacuum extraction pipeline. The water ring vacuum pump is connected to a vacuum pump water tank. The upper end of the mixing tank also has a feed inlet, which is used to connect to a batch mixing tank or other preparation tank via a pipeline.

[0005] Furthermore, the upper end of the mixing tank is also provided with an vent with a valve.

[0006] Furthermore, the lower end of the mixing tank is provided with a drain outlet equipped with a valve.

[0007] Furthermore, the cooling water return port is connected in sequence to the cooling tower, the workshop cold water tank, and the inlet water pump via pipes. The output end of the inlet water pump is connected to the cooling water inlet, forming a complete cooling circulation loop.

[0008] Furthermore, the inner steel plate of the mixing tank is 6mm thick, the outer steel plate is 4mm thick, and the gap between the intermediate layers is 45mm.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] (1) Low-temperature stirring and gas-liquid separation under vacuum prevents material loss and plays a protective role; the tank jacket is the equipment cooling system, thereby achieving cooling and low-temperature mixing; it has a small footprint, low cost, low loss, and wide application.

[0011] (2) Solution: The old-style mixing tank could not operate at low temperature and negative pressure and transport materials in a closed manner, thus improving the safety and effectiveness of the product. Attached Figure Description
