Hp-dmh Series Dry Material Preheater Pressure: High Pressure

About HP-DMH Series Dry Material Preheater:-


1. High preheating quality

It adopts tangent, different speed, radius dry material mixing and heating technology, mixing blade stirs materials while heating to make materials contact heat transmission surface of equipment directly to realize efficient heating.

2. Fast heat transmission and high temperature

Adopt efficient high temperature tank patent technology (invention patent number: ZL 2012 1 0124643.8), overall heating patent technology (invention patent number: ZL 2004 2 0018996.0), mixing blade heating patent technology (invention patent number: ZL 2006 2 0085174.3), discharge gate heating technology, lining plate and tank seamless connection technology.

3. Guarantee dry material particle size distribution

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

4. Temperature measurement is accurate

Adopt new type temperature measuring technology (patent number: ZL 2014 2 0490132.2), temperature and heat measuring responsiveness and anti-interference performance is improved.

5. Perfect air tightness

Adopt double metal ring sealing (patent number: ZL 2014 2 0490187.3) to form multiple sealing, and no carbon powder is leaked from shaft end of mixing blade.

Adopt hydraulic rotary lock door with excellent airtightness. Sealing surface will never worn out, airtightness is reliable, and no material is leaked from discharge gate.

6. Fast discharge, no material residue

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.

7. No powder is leaked during material discharge

Sealing hopper seals discharge door completely, no powder is leaked during material discharged. Hydraulic executive mechanism of discharge door is outside of sealing hopper for convenient observation and maintenance.

8. High wear-resistance

Overlying wear-resistant weld layers are at the surface of mixing blade, rigidity of wear-resistant layer is up to HRC60-65, and service life of mixing blade is 20 years.

Lining plates use new type wear-resistant manganese steel material with high 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. Mixing blade structure suitable to high temperature work environment

Bearing moves when mixing blade stretches longer under heat to avoid bearing blockage caused by mixing blade stretching longer. Bearing chamber has cooling structure which guarantees normal work temperature of bearing and it extends service life of bearing.

Bearing chamber has cooling water jacket to guarantee work temperature of bearing under high temperature and extend its service life.

Mixing blades run normally under high temperature.

10. Reliable operation

Transmission system is composed of master motor, P series hard teeth reduction gear, bearing capacity of which is 3 times of common teeth reduction gear, and guarantees high bearing capacity of transmission system. In case of hard things falling, the equipment will not be damaged.

11. Low noise

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