Vacuum grease smearing and sealing device for freeze dryer

Abstract

The invention relates to the field of freeze dryers, in particular to a vacuum grease smearing sealing device for a freeze dryer. The invention aims to provide the vacuum grease smearing sealing device for the freeze dryer. According to the technical scheme, the vacuum grease smearing sealing device for the freeze dryer comprises a freeze dryer body, an operation control screen, a cold trap cover, a cold trap sealing ring, a sealing ring smearing system, a glass cover smearing system and a residual grease wiping system; and the freeze dryer body is connected with the operation control screen. According to the vacuum grease smearing sealing device, automatic vacuum grease smearing of the freeze dryer sealing ring after freeze drying is completed is achieved, vacuum grease smearing operation is carried out on the whole annular bottom of the sealing ring under the condition that the sealing ring is not moved, the problem that the sealing ring is difficult to reset after being separated is avoided, vacuum grease smearing is carried out on the edge of the bottom of a glass cover, and redundant vacuum grease can be wiped.

Description

technical field [0001] The invention relates to the field of freeze dryers, in particular to a vacuum grease coating and sealing device for freeze dryers. Background technique [0002] Freeze dryers originated from the vacuum freeze-drying technology in the 1920s. In the 21st century, vacuum freeze-drying technology has been widely used in fields other than medicine, biological products, food, blood products, and active substances. [0003] At present, in the prior art, after the use of the freeze dryer, vacuum grease needs to be applied to the sealing ring of the freeze dryer, and vacuum grease needs to be applied to the edge of the glass cover at the same time. Pull it out for vacuum grease application, but the sealing ring and the freeze dryer are tightly fitted. After pulling out, it is difficult to reinstall the sealing ring to its original position, and at the same time, it will reduce the sealing performance of the sealing ring , in the process of applying vacuum gre...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the problem in the prior art that vacuum grease needs to be applied to the sealing ring of the freeze dryer after the use of the freeze dryer, and vacuum grease needs to be applied to the edge of the glass cover at the same time, but in the manual application process, the sealing ring needs to be manually Pull it out for vacuum grease application, but the sealing ring and the freeze dryer are tightly fitted. After pulling out, it is difficult to reinstall the sealing ring to its original position, and at the same time, it will reduce the sealing performance of the sealing ring , in the process of applying vacuum grease to the glass cover, the amount of vacuum grease cannot be accurately controlled, resulting in some excess vacuum grease remaining on the edge surface of the glass cover. If the glass cover is solidified, the vacuum grease cannot fill and seal the gap between the sealing ring and the glass cover when the glass cover is used again, which affects the normal operation of the freeze dryer. The purpose of the present invention is to provide a vacuum grease coating sealing device for the freeze dryer.
