Specification
1. The core internal element is micron porous tubes which is under hung in the filter body, and the bottom is equipped with an auxiliary filter zone for making sure the filtration effect.
2. The filter internal structure is not only having less spacerequirement, but also have more filtration area, main solution is to solve the medium quick filtration on the top, and the middle or the bottom have auxiliary filtration, then the trapped filter cake could be washed and dry pressed.
3. INOCO-DS-A6 could finish the processing of filtering, static washing, dry pressing in one machine, it shortens the process, avoids the outside pollution to the cake, closed filtering, clean production; and the pneumatic quick open cover has simple operation.
4. Discharging the dry cake and reducing the follow-up process energy consumption.

INOCO-DS-A7 Series tube type automatic filter / thickener
Equipment description
INOCO-DS-A7 series tube type automatic filtration system can automatically regenerate filter elements without stopping the system. It is a fully automatic self-cleaning filter that effectively reduces the need for manual cleaning and does not require replacement of filter elements. It is widely used in continuous production, high-risk operating environments, and situations where metal filter elements are not suitable.
Working principle
The feed liquid with the catalyst enters from the outside of the filter and passes through the filter material from the outside to the inside.
Solids collect on its surface and form a uniform cake. The cake remains on the lter elements due to their concave-convex pro le and a continually maintained pressure di erential across them.
When the pressure drop to the set value, inlet and outlet valve turn o ff, compressed air flow into the filter and dry the filter cake, in the backwashing processing, the particles will be removed, and the filter element could be regenerate.
After the pre-filtration step comes a filtration step of varying length, which terminates as the feed stops. Unloading is achieved through reverse blowing, but there is no need to empty the liquid inside the machine. This step causes the filter cake to fall off and sink to the cone of the filter within seconds after backblowing, and then the filtration cycle returns to normal.
The thickened thick slurry is discharged from the machine by opening the discharge valve in the next filtration cycle, which has no impact on the filtration steps.

Character
Dry and wet material discharge;
Filtered solids are dehydrated and discharged via gas backflushing;
Can also be used for filter cake re-reaction;
Continuous thickening;
Permits uninterrupted filtration, with solids flushed back into the liquid for slurry discharge;
Suitable for processes requiring continuous filtration;
Sanitary filters;
Designed to meet the high production standards of pharmaceuticals and fine chemicals. All product contact surfaces and components can be effectively cleaned.
Back-blown
Whether using dry or wet discharge, discharge is achieved by applying reverse pressure to the filter rod.
The unique structure facilitates backflushing:
During backflushing, the filter cloth rapidly expands outward, particularly in the area where the filter cake adheres, causing vertical cracks in the filter cloth. The instantaneous backflushing of gas (such as air or nitrogen) within the filter cloth rapidly ejects the cracked filter cake from the cloth.
