PD type filter bag hoist discharge centrifuge

structures and propertie…

structures and properties:

PD centrifuges are filter equipment with hermetic closure procedure task, intermittent operation and hanging bag off-site discharge. The material is fed into the drum from the top; under the action of the centrifugal force filed, the liquid-phase passes through the filter medium and is discharged out of the machine, while the solid-phase material is retained inside the drum; after the machine is stopped, the liquid-block plate together with the filter bag is hoisted with the sling out of the machine and transferred to the designated discharge site. The centrifuge has such features as smooth start-up, adjustable separating factor, large volume, high efficiency, easy & convenient operation, quick discharge, good safety, clean environment, low labor strength, etc.
Model PD centrifuge has got rid of traditional suspending type of leg-support, instead, it adopts flat-plate counterweight and high-viscosity damping agent vibration isolator for absorbing the vibration and the installation requires no concrete foundation
Model PD centrifuge are all with fully-open large cover, quick-open-type hanging bag discharging, and have such features as motor’s over-heat, overload & over-current protection as well as other interlock protection.

It is applicable to the separation of suspension containing solid-phase granules with the diameter greater than 0.01mm. And it is especially applicable to the filtering of toxic and flammable materials. It has found wide applications in such trades as chemical, pharmacy, food, light industry, etc. For example: gypsum, thiamine, mirabilite, ferric sulfate, copper sulfate, nickel sulfate, potassium chloride, acetic acid, borax, soda, rubber additives, dye, plastic raw material, soap, grease, all kinds of resins, food salt, sodium glutamate, food additives, starch sugar-making, vitamins, antibiotics, herbicide, insecticide, the dehydration of such mineral fines as copper, zinc, aluminum, etc.
