Properties and Uses

GKH Series automatic siphon centrifuge is a solid-liquid separtion equipment which adopts continuous operation and intermittent discharging .Its production capacity and separation effect is better than GK(F) Centrifuge.

This machine is controlled by PLV and regulates speed by frequency convertor ,braking system applies dynamic braking and regenerative braking ,the whole separation process is automatic circulative process and manual operation model is applicable to be changed over from automatic operation mode.

GKH Series automaci siphon centrifug eis more suitable for separating such produc as small solid phase granularity and which is hard to be separated.It is widely used in pharamaceutical Chemical and foodstuff industry(E.g.starch ,calcium  phosphate,sodum bicarbonate.

GKH Woring principle:

Except centrifuge forece like the other common centrifuge,siphon centrifuge also has a kind of siphon draught force similar to vacuum pipe.

When the centrifuge is of no load,the counter-pulse pipe feeds the liquid to siphon chamber and the liquid is forced to the clearance through the via hole on the drum of the siphon chamber,.The air of siphon pipe is eliminated and a layer of liquid forms on the filtering media,so as to make the feeding more even.Then feeding starts,the siphon pip rotates to a certain position and it turns to a lower position required after a certain period ,When the feeding is finished ,the siphon pipe turns to the lowest position(Max ,diameter place of siphon chamber)After the suspension liquid comes into the drum,solid produducts are left on the filter cloth while the liquid is forced to go through the filter cloth and internal drum and collected in the clearance between internal and external drum,then it flows into the siphon chamber through drum and via hole,Next ,the liquid will be draught and scraped by scraper which is driven by oil cylinder,And then the solid falls out through hopper,When discharging is finished ,centrifuge begins to clean the mesh,The siphon centrifuge not only washes to siphon chamber,By controlling the upper and lower roataion of siphon pipe,liquid can counter-pulse wash the filter mesh from the internal drum,the washing duration and times are decided by product characteristic and when the washing is finised ,carry out the next circulative processing cycle.

GKH Main Characteristics:

1.Comparing with common horiaontal centrifuges with the ssme specification,the production capacity can be raised by 40% to 60% and the moisture content of filter cake is lower.

2.Changing the postion of siphon pipe port can regulat the filter speed,thus ,different filter speed can be realized during different process as feeding separation ,filtering ,washing and dehydration,The centrifuge will be alwasys under best working condition and the equipment operates stablly and the vibration and noise are rather low.

3.When the scaper is finishedm,the regenearte liquid will be fed from the siphon feeding pipe to regenerate and resuspension the filter cake ,bake flush and remove the left filter cake

4.The automatic residual cakes removing device is optional (have owend the national patent)
