– Hwapeng HP-CPK Series Carbon Paste Kneader – Hwapeng

HP-CPK Series Carbon Paste Kneader (invention patent number: ZL20141 0430160.X,ZL201420490132.2) adopts a number of patented technologies, which guarantee excellent paste kneading quality, best sealing performance with no dust and pitch smoke leakage.
Technical Performance
1. High mixing quality
It adopts intersectant, synchronous mixing blade technology from Japan. Mixing blades radius exceeds the middle of tank which en- larges 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.
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.
2.Fast heat transmission and high temperature
Adopt efficient high temperature tank patent technology (invention patent number: ZL 2012 1 0124643.8) (this is customized configuration), overall heating patent technology (invention patent number: ZL2004 2 0018996.0), mixing blade heating patent technology (invention patent number: ZL 2006 2 0085174.3) (this is customized configuration), discharge gate heating technology, lining plate and tank seamless connection technology.
3. Guarantee dry material particle size Proportion
Use special equipment to process inner diameter of tank and bearing hole of tank end plate, machining precision is high and it guarantees gap requirement between mixing blade and tank to prevent particles from grinding during dry mixing and heating.
4. Pitch distribution is uniform
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.
5.Temperature measurement is accurate
Adopt new temperature measuring technology (patent No.:Z2014 2 0490132.2)to improve temperature measuring performance of thermo-responsive and anti-interference.
6. Perfect air tightness
Adopt combined overlapping metal ring to form multiple sealing(patent number: ZL 2014 2 0490187.3) to guarantee no carbon powder leakage from shaft end of mixing blade; Hydraulic rotary lock discharge gate has excellent air-tightness, sealing surface of which never wears out so that air-tightness is reliable and no material leaks from discharge gate.

7. Fast discharge, no material residue
Mixing blades push material spirally and material is dis- charged fast. Discharge gate is at the bottom of tank, material is discharged out completely without residue, material dis- charge time is less than 2min, and there is no material left in the tank.
8. High wear-resistance
Mixing blade is surface welded with wear-resistant layers with the rigidity up to HRC6065, 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.

9.Bearing structure of mixing blade is reliable
Mixing blade shaft adopts self-aligning roller bearing and double-direction thrust bearing design which overcomes axial force of mixing blade and prevents mixing lades 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.
10.Reliable operation of transmission system
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, guarantees 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).
11. Low noise
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.
12. PLC full automatic control
PLC control and internet communication is adopted 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.
