Description

Technical Field

[0001] The utility model relates to the technical field of degassing of liquid materials, in particular to a device for removing bubbles. Background Art

[0002] In production, the degassing process is usually carried out at room temperature. By forming a sufficient vacuum degree in a confined space, the residual bubbles or small molecules in the liquid material are removed to obtain a uniform liquid material with little odor. The process operation is simple and convenient, and it is widely used in the industry. However, for some liquid materials with low viscosity, it is easy to obtain a large vacuum degree in an instant during the degassing process, so that the residual air or volatile additives in the material will swell instantly due to the imbalance of atmospheric pressure, causing the liquid material in the container to overflow, which will not only affect the degassing efficiency of the material and cause material loss, but also pollute the box and take a lot of time to clean.

[0003] There are also some vacuum boxes for degassing on the market. For example, the patent document with patent application number 202221232130.4 and patent name "A bubble removal device for cream production" discloses a bubble removal device that can adjust the vacuum degree. The device extends into the mixing barrel through the motor output shaft to drive the stirring rod for stirring. This structure has some disadvantages. For example, a sealing ring needs to be installed between the output shaft and the mixing barrel for sealing, which is cumbersome and inefficient to install. After a period of use, the sealing ring is prone to aging, resulting in poor sealing effect, which can easily cause the vacuum box to leak air or liquid.

[0004] The utility model is made based on the above situation. Utility Model Content
