Product Advantages

● Continuously supply liquid to the machine tool without being interrupted by backwashing.

● 20~30 μm filtering effect.

● Different filter paper can be selected to cope with various working conditions.

● Robust and reliable structure and fully automatic operation.

● Low installation and maintenance costs.

● The reeling device can peel off the filter residue and collect the filter paper.

● Compared with gravity filtration, vacuum negative pressure filtration consumes less filter paper.

Technological Process

Outline Layout

Operation Mode

● Unpurified dirty processing liquid enters the dirty liquid tank (2) of the vacuum filter through the return liquid pump station or gravity reflux (1). The system pump (5) pumps the dirty processing liquid from the dirty liquid tank into the clean liquid tank (4) through the filter paper (3) and the sieve plate (3), and pumps it to the machine tool through the liquid supply pipe (6).
● The solid particles are trapped and form a filter cake (3) on the filter paper. Due to the accumulation of filter cake, the differential pressure in the lower chamber (4) of the vacuum filter increases. When the preset differential pressure is reached (7), the filter paper regeneration is started. During regeneration, the continuous liquid supply of the machine tool is guaranteed by the regeneration tank (8) of the vacuum filter.
● During regeneration, the scraper paper feeding device (14) is started by the reducer motor (9) and outputs dirty filter paper (3). In each regeneration process, some dirty filter paper is transported outwards, and then it is reeled by the winding device (13) after being discharged from the tank. The filter residue is scraped off by the scraper (11) and falls into the slag truck (12). The new filter paper (10) enters the dirty liquid tank (2) from the rear of the filter for a new filtering cycle. The regeneration tank (8) remains full at all times.
● The whole process flow is fully automatic and controlled by various sensors and electric control cabinet with HMI.

Main Technical Parameters

LV vacuum belt filters of different sizes can be used for single machine (1 machine tool), regional (2~10 machine tools) or centralized (the whole workshop) filtration; 1.2~3m equipment width is available for selection to meet customer site requirements.
