The vacuum pump generates negative pressure, thereby creating a pressure difference on both sides of the filter medium as a driving force for the filtration process.
The principle of vacuum filtration is to use the action of a vacuum pump to create a negative pressure in the filter, thereby forming a pressure difference on both sides of the filter medium as a driving force to remove the liquid in the suspension and leaving the solid particles on the filter cloth, thereby separating the liquid from the solid.
The filtration process uses a vacuum pump to generate negative pressure and generates a pressure difference on both sides of the filter medium as a driving force. It is divided into processes such as liquid suction, air blowing, dealkalization, and air suction.
answer: The principle of vacuum filtration is to use the action of a vacuum pump to create negative pressure in the filter, thereby forming a pressure difference on both sides of the filter medium as a driving force to remove the liquid in the suspension and leaving the solid particles on the filter cloth, thereby separating the liquid from the solid. 1# steinback
The principle of vacuum filtration is to use the action of a vacuum pump to create a negative pressure in the filter, forming a pressure difference on both sides of the filter medium (filter cloth), and the liquid in the suspension is pumped away, while the solid particles remain on the filter cloth, thereby separating the liquid from the solid.

Working principle: The work of the vacuum permanent magnet filter is completed by the continuous actions of feeding, blowing ore and adsorbing into cake, dehydration, unloading, cleaning and other parts. The vacuum permanent magnet filter mainly relies on the open-circuit magnetic system arranged inside the cylinder to form a filter cake. When the magnetic material enters the rich box, the solid-phase magnetic material in it is quickly adsorbed on the filter cloth of the cylinder in the form of magnetic clusters under the action of magnetic force and the gravity of the particles themselves. Due to the upper feeding, the effect of stratification of minerals in the filter cake according to particle size is more obvious, so the filter cake is thick and has good air permeability. As the cylinder rotates, it enters the dehydration area. Under the action of vacuum, the residual moisture in the filter cake penetrates the filter cloth and is extracted through the two vacuum pipes in the filter chamber and the distribution head. The dehydrated material is blown down by compressed air in the discharge area. After unloading, the filter cloth enters the cleaning area. Cleaning is carried out alternately with air blast and water. The compressed air forcibly blows the water out from the cylinder, forming a better cleaning process, preventing the pores of the filter cloth from being blocked, and preparing good conditions for the next dehydration of materials.
This post was last edited by Qingtan Xiaolong on 2010-3-22 16:21 Vacuum filter is a highly automated filtration equipment, a process that separates solid particles suspended in liquid or gas. Its basic principle: Under the action of pressure difference, the liquid (or gas) in the suspension passes through the permeable medium (filtration medium), and the solid particles are trapped by the medium, thereby achieving the separation of liquid and solid. This machine uses filter cloth or filter mesh as the medium, arranges the slurry horizontally on the filter medium, and makes full use of the gravity of the slurry and vacuum suction to achieve solid-liquid separation.
