HP-CPK Series Carbon Paste Kneader

It adopts intersectant, synchronous mixing blade technology from Japan. Mixing blades radius exceed the middle of tank which enlarge actuating area; two mixing blades have the same spiral climbing direction but different rotating direction, one mixing blade pushes material to the middle and the other one pushes to both sides, material flows like “8” in the tank.

Introduce in the original mixing blade from Japan, the section of the blade is elliptic which pushes materials to move along with vertical direction of the elliptic section, squeezing action is intensified, material granules are fully mixed, mixing and kneading effect is strengthened. Elliptic section does not stick to material easily and the surface of mixing blades is free of materials.

Adopt efficient high temperature tank patent technology (this is customized configuration), overall heating patent technology, mixing blade heating patent technology(this is customized configuration), discharge gate heating technology, lining plate and tank seamless connection technology.

Use special equipment to process inner diameter of tank and bearing hole of tank end plate, machining precision is high and it guarantee gap requirement between mixing blade and tank to prevent particles from grinding during dry mixing and heating.

Pitch distribution device is mounted on cover to add pitch into the tank uniformly through multiple points, inclusion of dry material block in paste is avoided. The device is heated by heat transfer oil to avoid solidified pitch blocking the device.

Adopt new temperature measuring technology to improve temperature measuring performance of thermo-responsive and anti-interference.

Adopt combined overlapping metal ring to form multiple sealing to guarantee no carbon powder leakage from shaft end of mixing blade; Hydraulic rotary lock discharge gate has excellent airtightness, sealing surface of which will never worn out that airtightness is reliable with no material leakage from discharge gate.

Mixing blades push material spirally and material is discharged fast. Discharge gate is at the bottom of tank, material is discharged out completely without residue, material discharge time is less than 2min, and there is no material left in the tank.

Mixing blade is surface welded with wear-resistant layers with the rigidity up to HRC60-65, and service life of mixing blade is 20 years. Tank lining plates use new type wear-resistant manganese steel material with excellent strength after thermal treatment. Service life of lining plates to produce anode is 15 years and it is 1 year to produce cathode and carbon electrodes.

Mixing blade shaft adopts self-aligning roller bearing and double-direction thrust bearing design which overcomes axial force of mixing blade and prevents mixing blades from axial shifting and service life of bearing is longer. Bearing structure is fixed on one side and movable on the other side, which eliminates influence of thermal expansion and prevents mixing blade from seizing after it is heated by heat transfer oil.

It adopts hard teeth reduction gearbox and synchronous gearbox split structure with full lubrication and reliable operation. Hard teeth reduction gear, bearing capacity of which is 3 times of common one, together with gear coupling, guarantee high bearing capacity of transmission system. Hydraulic clutch can adjust transmitted torque according to the load to provide overload protection, and allow the machine to restart with load in case of some special conditions (such as restart after stopping during running).

It is machined by special equipment, to get good concentricity, making the operation smooth, service life long, and operation noise of the entire machine less than 80dB.

PLC control and internet communication is adopt to measure, display and transmit equipment running and status parameters at real time (optional configuration). Three kinds of operation mode—internet automatic, single machine automatic and manual—guarantee the machine itself can run automatically no matter if upstream and downstream machines are automatic.
