PPTD Top Discharge Centrifuge

Adopting traditional structure, shell body is separated with chassis. Shell cover is sealed cooperatively with shell body by flange and locked Firmly by a big caver that is opened with the help of balancing vat.

There are feeding pipeline, washing pipeline, sight glass, viewing light. Frictional braking device deployed in the cover and a frictional starting-up clutch.

 

Working Process Diagram

Which are in accordance with the GMP Norm and the requirement of environmental protecting. Started up stably under frequency conversion control system (a clutch is another choice), the motor drives the revolving drum through a transmission system to give the drum a fast and circularize revolve, thus a centrifugal force field is generated, The revolving speed of feeding, cleaning and solid liquid separating can all be adjusted in a certain speed range (from O to the rated revolving speed): Under the effect of centrifugal Force, the material is evenly distributed on the drum wall to take off the liquid. Drilling through the gap between the solid phase material and filter net(or a filter bag), the liquid phase is thrown into the empty chamber of the shell through the drum wall hole, and then discharged while the solid phase remains in the drum. Since liquid material is fed in the feeding pipeline and the washing Water from the washing pipeline, there are special valves to control the feeding and washing. After the dehydrating and washing. You can halt the centrifuge, open the upper cover and discharge the material by a distinguishingly designed balancing facility.

 

Performance and Usage

Since the PPTD top discharge centrifuge has a good adaptability to the materials, it can be used to separate the fine geains of micron size, to dehydrate the large articles, as well as to apart all kinds of suspension that was difficult to separate. The grains are discharged manually and will not be broken at random. For example, it suits for industrial materials such as gypsum, ammonium sulphide, bluestone, potassium chloride, borax, dyestuff, resin, pesticide, pharmaceutical materials such as salt, monosodium glutamate, food additive, starch, sugar, flavorig, antibiotic, vitamin, mining products like copper, zinc and aluminum etc, and other industries such as environmental protecting (sullage and sewage processing)etc.

 

Main Features

● The centrifuge has a novelty structure while it is convenient for operation and maintenance.

● The Centrifuge adopts whole sealing structure to improve the working condition, and meets the requirement of GMP Norm and erviranmental protection, The facility is filled with Nitrogen to meet the explosion proof demand.

● Adopted with big cover structure, it is convenient to discharge the material and thoroughly wash the space between the shell and drum.

● The lid is equipped with a mechanical, balancer, so it is less labor cost and needs no energy.

● Frequency conversion system is adopted to assure a stable start-up. Program can be predetermined to ensure a complete automatic process including feeding, filtering, washing and discharging etc. It adopts dynamic (feedback) braking without friotion powder pollution and friction heat, so it is much safer.

● Since both the inner and outer surface have been polished, no Dead angle exists and completely transited smoothly, an optimal Washing effect can he achieved when a CIP cleaning svstem (material cleaning and machine cleaning) is available.

● Grains can be well preserved.

 

Material Choices

● Frequency conversion plus dynamic breaking (feedback breaking).

● Vibration protection.

● Nitrogen protection, Oxygen content detection(including Nitrogen controlling).

● Automatical shut down with the cover opening and automatic cover locking against the its falling down.

● Liquid seal equipment in the liquid outlet[or vertex separation.

● CIP cleaning facilities.

● Explosive proof motor, static electricity proof transmission belt.

● Other demands.
