Trend of Solid-liquid Separation Production Line from Filter Press to Decanter Centrifuge

Filter press and horizontal screw centrifuge are common solid-liquid separation equipment, the amount of retention is very large, rich sunshine and you solid-liquid separation production line machine from filter press to horizontal screw centrifuge technical advantages:

1. horizontal centrifuge without filter media,

Filter press pressure filtration of filter medium (filter) to separate solid and liquid, need to use high pressure water to avoid filter belt obstruction; horizontal centrifuge high speed rotation to produce Li Xin position to separate solid-liquid centrifugal settlement, It is not suitable for filter medium because of filter screen, which bypasses the common filter clogging problem in filter operation.

2. horizontal screw centrifuge is widely applicable

Filter press can also most of the solid-liquid separation, but the oil, viscosity and other strong adhesion of solid-liquid separation needs pretreatment and incomplete separation; horizontal screw centrifuge separation adaptability, can achieve solid-liquid two-phase separation and solid-liquid three-phase separation, better adaptability to solid-liquid separation.

3.Automation of production line of 3. horizontal screw centrifuge:

Filter press is intermittent operation of manual cutting slag, loading and unloading belong to intermittent operation most or need manual coordination is not conducive to the formation of automatic production line to improve production efficiency; Horizontal centrifuge can realize automatic loading and unloading continuous production automatic loading and unloading can form automatic production line production efficiency.

4. horizontal screw centrifuge parameters adaptive adjustment ability,

In the process of solid-liquid separation and dehydration, the belt filter is adjusted according to the working conditions, and the parameters such as speed, tension, dosage and flushing pressure often depend on the experience of the operator, which requires high operation technology.

5.Low consumption of pre-treatment material for 5. screw centrifuge

Because filter press filter medium (mainly filter net) mesh will not be very small, so filter particle size can not be too small, small particle size should also add a lot of flocculant complex to synthesize large groups to facilitate filtration, which results in the consumption of additional pretreatment materials. In horizontal centrifuge, fine sludge can also be separated from water, so the dosage of flocculant is less, saving material input and reducing production cost;

6. horizontal screw centrifuge production line environment is good:

In addition to the main filter press, the filter press also needs to add medicine and feed conveyor washing pump air compressor and other ancillary equipment, large area, the whole machine is difficult to seal, high pressure cleaning water mist and odor pollution environment, poor production line environment;

7. low maintenance requirements for horizontal centrifuge

The number of easily damaged parts in the fuselage accessories of filter press is many times that of centrifuge. Maintenance is not only labor intensity but also high cost.

It can be seen from the above comparison that the comparison of the same processing conditions with the filter press has great technical advantages, and the solid-liquid separation production line from the filter press to the horizontal screw centrifuge is the development trend.
