Five Points in Which Rotary Dryer Is Upgraded

Rotary dryer usually cast iron of the head of the hot end of the sealing structure sealing the outer ring fixed to the frame of the fluidized bed furnace, the built-in 'T' shaped fixed gasket and the fixed in simplified dynamic sealing flange forming labyrinth seals. And after long-term use of the of rotary dryer ends Simplified multiple crack and deformation, Simplified whole cast iron back gauge circle fragmentation, dynamic sealing flange come off the 'T'-shaped constant seals killed, external cast iron the sealed outer ring pushed bad, thus resulting in the device head seal failure.

Of Hongsen the experts through research found this years due to the operation of the dryer, the head cylinder and sealing devices caused by long-term high-temperature and off on temperature change, whether in production or in peacetime, should pay attention to drying Equipment maintenance and repair work. Below you explain the transformation of key points of the new rotary dryer.

1. The ordinary steel plate with a thickness of 12mm to produce a 600mm head simplified and its head socket weld thick 16mm length 90mm head retaining ring of heat-resistant steels, heat resistant steel plate with a thickness of 12mm to produce a sealing of the outer diameter of 2700mm stopper The snare welding appropriate position of the cylinder in the finished head;

2. The sealing outer ring of the inner diameter of 2800mm, produced with a thickness of 12mm of the heat resistant steel plate welded to the seal on the flange ring of the ordinary steel production;

3. With a thick 16mm heat-resistant steel plate view original size produced a split backgauge ring (8) consisting of;

4.Prepare the briquetting 3 and 1 mm thick spring steel, spring leaf borrow 3.2 × 52m the rotary kiln head the seal spring leaf;

5. The machine cylinder head cylinder and bake corrected good weld and split backgauge ring bolted to the head Simplified; After sealing flange at suitable location with the framework...
