Description

TECHNICAL FIELD

[0001] The utility model relates to a vacuum filter technology field, specifically to a vacuum filter convenient to install. BACKGROUND

[0002] The vacuum filter, also known as a vacuum filter machine, is a device that works based on the principle of negative pressure (vacuum) and is mainly used for the separation and collection of impurities in liquids or gases in a laboratory. The working principle of the vacuum filter mainly relies on the negative pressure environment. The gas in the filter cartridge is extracted by an air extraction system (such as a mechanical pump, a root fan, etc.), so that a negative pressure (vacuum) environment is formed inside the filter cartridge. Under the action of negative pressure, the liquid or gas to be filtered is introduced into the filter cartridge, and the impurities and particles in it are effectively intercepted and left on the surface or inside of the filter medium (such as a stainless steel filter screen or filter paper) when passing through the filter medium, while the clean liquid or gas continues to flow through the filter medium.

[0003] In the current prior art, the vacuum filter needs to go through an installation process before use, and the key is to ensure the sealing between the filter cup, the filter membrane placement base, and the liquid collecting bottle. However, the existing technical method usually relies on a clamp to hold the filter membrane placement base and the filter cup to achieve their close fit and sealing effect, and a rubber is provided between the liquid collecting bottle and the filter membrane placement base for sealing. However, this way of using a clamp needs to constantly adjust the angle of the clamp to achieve the ideal sealing state in actual operation, which is relatively cumbersome and time-consuming.
