Description

Technical Field

[0001] This utility model relates to the field of vacuum filtration equipment technology, and specifically to an anti-detachment sealing device for vacuum filtration equipment. Background Technology

[0002] Vacuum filtration is an operation in which liquid in a suspension permeates through a filter medium under the action of a driving force or other external force, while solid particles and other substances are trapped by the filter medium, thereby separating the solids and other substances from the liquid. To accelerate the permeation of liquid through the medium, reduced pressure filtration can be used, which usually involves placing the side of the liquid permeating through the medium under negative pressure.

[0003] Current problems:

[0004] 1. The commonly used vacuum filtration pipeline is a rubber hose that is directly connected to the vacuum filtration flask and the vacuum filtration machine. It often comes loose during use, causing vacuum filtration failure.

The diameter of the inner tube of the filter tube connector is larger than that of the inner tubes of the filter bottle connector and the fixed connector. The inner tube of the filter tube connector is inserted into the inner tubes of the filter tube connector and the fixed connector to form a zero-gap fit. The inner tube of the filter tube connector is inserted onto the outer wall of the inner tube of the fixed connector and the filter bottle connector. Through the threaded fit, the two ends of the filter tube connector are rotated onto the fixed connector and the filter bottle, respectively.

[0010] As another preferred solution, the inner tube of the fixed connector is provided with a sealing ring at the joint with the bottom end of each outer tube.
