Background technology
Piston push centrifuge uses full automatic continuous working, and suspension quickly forms filter cake after entering rotary drum, in pusher
During the continuous reciprocal passage of mechanism, the filter cake of formation is continuously elapsed to discharge port successively.It is filtered during this passage
Under the influence of centrifugal force, the filtration channel that the gap across particle is formed constantly is divided liquid in cake through sieve
It separates out.Cake layer reaches the filter cake moved forward below after rotary drum mouth and squeezes out rotary drum, completes solid-liquid separation process.From work
The rotary drum mouth that principle can be seen that piston push centrifuge is open type, and without lip ring, suspension enters necessary after centrifuge
A bit of cake layer is quickly formed, this section of cake layer becomes one section of cofferdam, the suspension entered below is blocked in rotary drum, prevent
Suspension sprays rotary drum.That is, the filter cake that piston centrifuge is formed with suspension, instead of blocking for other perforated wall centrifuges
Liquid plate.
Piston push centrifuge has that automatically continuously operation, yield is high, Washing of Filter Cake is efficient, operates steadily, does not rush
The incomparable advantage of other centrifuges such as load is hit, low energy consumption for specific yield.So can be used in several class centrifuges
In the case of, piston push centrifuge can become first-selected type.
But the operation principle of piston push centrifuge, determine its be only used for high concentration, bulky grain crystal suspension,
Usually require that the concentration of suspension is not less than 30%, average diameter of particles is not less than 0.1 millimeter.Concentration is low or particle is small can not
Normal use.Which limits the application ranges of piston push centrifuge.In separation machinery, the application of piston push centrifuge
Range is most narrow, the suspension that piston push centrifuge can detach, and other type centrifuges can almost detach.
Therefore need it is a kind of it is simple in structure, stability is high, have a wide range of application and be conducive to cloth separation sedimentation-filtration dewatering
Piston push centrifuge.
