For realizing above-mentioned purpose; The technical scheme of the utility model is: compound heating oar blade type desiccation machine comprises that drive unit, wheel casing, driving toothed gear, follower gear, driving chain, cylindrical shell, loam cake, two hollow rotating shafts, hollow blade, pug import, weep hole, steam inlet, gas approach, discharge port, vapour outlet, exhanst gas outlet constitute; Drive unit is as propulsion source, and through the rotation of multistage in the driving chain drive gear casing (speed change) gear, promptly wheel casing is driven by drive unit through driving chain; Gearbox output shaft is connected with chain with the outer driving toothed gear of casing, driving toothed gear and follower gear engagement; Two hollow rotating shafts (12) are fixed with main driven gear respectively through the key mode of connection; Sludge drying handler main body is made up of two hollow rotating shafts (12), hollow blade (13) and cylindrical shell (18), and cylindrical outer casing is furnished with loam cake (11), loam cake and cylindrical shell sealing;
Two hollow rotating shaft left ends are provided with steam inlet (5), in the drying machine hollow rotating shaft, pass to steam, and steam gets into the hollow blade (13) that is communicated with hollow rotating shaft wet mud is carried out the indirect heating mummification; Cover on the desiccation machine be provided with successively from left to right pug filler (6), weep hole (9); Two tubular shaft right-hand members are provided with condensation-water drain (15), vapour outlet (14); The cylindrical shell bottom righthand side is provided with discharge port (16).
On cover and also be provided with visor (8), exhanst gas outlet (7), manhole (10).
Described drive unit is a motor; It is external that drive-motor, wheel casing, driving toothed gear, follower gear, driving chain are arranged on the sludge drying handler, is convenient to maintenance, and the material that reduces cylindrical shell corrodes, and work-ing life is longer.
Adopt steam and flue tail gas compound mode simultaneously mummification to be given in wet mud heating; Promptly when the common blade dryer of reservation is with the steam heating mummification; Be the chuck cavity structure at the desiccation machine cylindrical shell in addition; Bottom one side of cylindrical shell is that to adorn a gas approach be the flue gas inlet to cylindrical shell lower end one face down bonding; Opposite side at the cylindrical shell top exhanst gas outlet that is welded is flue tail gas outlet, and the high-temperature flue tail gas that produces during with boiler combustion is incorporated in the shell chuck cavity of desiccation machine, and its inlet all adopts carbon steel material with outlet.
The mummification thermal source is flue tail gas and compound steam effect, simultaneously wet mud is carried out the indirectly drying effect.
Desiccation machine passes in hollow blade in the steam indirect heating, in desiccation machine shell chuck cavity, feeds flue tail gas wet mud is carried out indirect heating, and flue tail gas plays insulation effect to complete machine simultaneously.
In the drying machine hollow rotating shaft, pass to steam; Steam gets into hollow blade wet mud is carried out the indirect heating mummification; Meanwhile, one face down bonding is adorned a flue gas inlet in the desiccation machine bottom in addition, and the high-temperature flue tail gas that produces during with boiler combustion is incorporated in the shell chuck cavity of desiccation machine; Make it carry out indirect heating, opposite side flue tail gas outlet that is welded at the desiccation machine top to the wet mud on the dry blade.The flue tail gas of introducing simultaneously plays good insulation effect to desiccation machine integral body, reduces the heat-energy losses in the wet sludge anhydration process.
The beneficial effect of the utility model is: on the basis of common blade dryer, improve.In drying machine, pass to when steam carries out the indirect heating mummification to wet mud; One face down bonding is adorned a flue gas inlet in the desiccation machine bottom in addition; Opposite side flue tail gas outlet that is welded at the top; The high-temperature flue tail gas that produces during with boiler combustion is incorporated in the shell chuck cavity of desiccation machine, and complete machine is produced insulation effect preferably, also can play indirectly drying effect to a certain degree to wet mud.The dry structure of the utility model and the sludge drying apparatus in comparison of other conduction heating, obvious energy conservation, mummification efficient height, good to environment protection are the ideal equipment of sludge drying.The mummification device energy conservation that adopts compound heating significantly, mummification efficient is high, reduce the mummification cost.
