Description

Technical Field

[0001] The patent of this invention relates to a pressure filtering group injection machine. Background Art

[0002] A solution is a uniform, stable mixture of at least two substances, in which the dispersed substance (solute) is dispersed in another substance (solvent) in the form of molecules or smaller particles. At room temperature, substances exist in three states: solid, liquid, and gas. Therefore, solutions also have three states. The atmosphere itself is a solution filtering device, a gas solution, and a solid solution mixture is often called a solid solution, such as an alloy. A general solution refers specifically to a liquid solution. There are two types of liquid solutions, namely, electrolyte solutions that can conduct electricity and non-electrolyte solutions that cannot conduct electricity. The filtration of general solutions is carried out by combining a funnel and filter paper, and it is necessary to wait for the liquid to be automatically filtered, which is very time-consuming and inefficient, and very inconvenient.
