And the heat transfer medium in the axocoel body of described hollow rotating shaft is conduction oil.
Advantage of the present invention and beneficial effect are:
1, originally be exclusively used in the spiral dryer of rubbish mud, comprise rotating shaft and helical blade, helical blade is uniform to be packed in rotating shaft, the hollow rotating shaft of axocoel body is established in its rotating shaft in being, helical blade is established the hollow screw blade of blade cavity in being, in the axocoel body of hollow rotating shaft, one end is blind end, in other end axocoel body, a baffle plate is set, on the hollow rotating shaft in baffle plate outside, offer the import of heat transfer medium blade cavity, this heat transfer medium blade cavity import is communicated with the blade cavity of the hollow screw blade of this side, on the hollow rotating shaft of blind end one side, be shaped with heat transfer medium blade cavity outlet, this heat transfer medium blade cavity outlet is communicated with the blade cavity of this side hollow screw blade, the hollow rotating shaft end in baffle plate outside connects a main shaft swivel joint by an axle sleeve, on this main shaft swivel joint, be provided with the import of heat transfer medium joint, on baffle plate, be provided with a heat transfer medium delivery line, this heat transfer medium delivery line one end connecting axle cavity, this heat transfer medium delivery line other end is communicated with by a delivery line swivel joint heat transfer medium joint of offering on main shaft swivel joint and exports, the present invention is simple in structure, separated realization by thermal medium and the rubbish mud that is dried is dried the indirect of rubbish mud, avoid polluting, processing speed is fast, safety energy-conserving environment protection.
2, the present invention adopts hollow rotating shaft and hollow screw blade to realize rubbish mud is rapidly and efficiently dried, and rubbish mud is by directly contacting and heat with hollow rotating shaft and hollow screw blade, and axially by rotation screw thread, is realizing transportation continuously.
3, the present invention by temperature and the hollow screw blade speed of gyration of Heat Transfer Control medium, realizes the accurate control of drying process, and processed rubbish mud do not contact with heat transfer medium, so can polluted product.
4, hollow rotating shaft rotating speed of the present invention is per minute five to six to turn, and the wearing and tearing that the driving force of generation causes hollow helical blade are very little, make rubbish mud gently dried, greatly reduce the generation of dust.
5, the heat transfer medium that the present invention uses is conduction oil, and conduction oil recycles, and has guaranteed to the full extent making full use of of heat energy, has effectively saved the energy and has reduced the cost moving.By using the operating temperature range of stainless steel material equipment of high-quality wide, allow to move under the high temperature of 1000 ℃, effectively raise drying efficiency, save drying time.
