9. using a kind of drying means of sludge heat drying system as claimed in claim 1, it is characterised in that including as follows Step:
1) water process is gone at the beginning of sludge:
Sludge is transported in dewatering cavity first and carries out dewater treatment, sludge is entered in dehydration tube from feed hopper, pressurizing unit Start working, extruding cylinder drives stripper plate to be compressed extrusion process to the sludge in dehydration tube by piston rod so that dirty Sewage in mud is drained into the bottom of dewatering cavity from the leaking hole in dehydration tube lower wall, then discharges progress from the discharge outlet of bottom Sewage is focused on, while while stripper plate is compressed extrusion process to sludge, and the crushing tooth of stripper plate bottom surface is by dirt Hard particles in mud are crushed, and not only improve the dewatering efficiency of sludge, and stripper plate is protected again;
2) sludge decentralized processing:
(1) sludge after dehydration tube dewater treatment is entered on the tilting table of scattered chamber from the right-hand member of dehydration tube, the same to time-division It is in bulk to put start-up operation, decentralized processing is carried out to the sludge on tilting table by multiple dispersal devices, electric rotating machine drives scattered The rotation of axle, so as to drive the rotation of dispersion impeller to carry out decentralized processing to extruding blocking sludge, not only causes after extrusion process Blocking sludge be ground into graininess, be easy to the drying and processing of follow-up sludge, and improve the dispersion rate of sludge again, accelerate dirty The processing speed of mud so that the sludge quality of subsequent treatment more preferably, slows down the operating pressure of drying box;
(2) at the same periodically to dispersal device carry out washing and cleaning operation, by expansion link by clean disk move down, shorten cleaning disk with The distance between dispersal device, then be transported to the water in water tank in expansion link from elastic delivery pipe by back suction pump, it is most laggard Enter to cleaning disk and sprayed away from the cleaning face of trying to get to the heart of a matter, so as to carry out washing and cleaning operation to dispersal device.
3) drying process of sludge:
(1) processing is dried in the inside that the sludge after disperseing is transported to drying box by the transmission of conveyer belt;
(2) before sludge enters drying box, the heater inside drying box is preheated, adding inside heating plate Heated filament is heated, then is distributed by the thermal hole of heater plate surface so that the temperature in drying box reaches the drying of sludge Temperature;
(3) after sludge is entered in drying box, heater continuous heating carries out drying operation to sludge, while stirring dress Put and operation is stirred to sludge, increase the surface area of sludge so that heat is fully contacted with sludge, so as to improve the baking of sludge Dry effect and quality;
(4) dried sludge passes through the cushioning effect of elastic buffer plate, further the drying time of extension sludge so that sludge Drying effect more preferably, enter back into mud-output trough, from mud-output trough discharge.
4) cleaning is repaired with checking:
Periodically the inside of the inside of dehydration tube, screen pack and drying box is cleared up and repaired, glutinous residual sludge will be glued Removed with impurity, consequently facilitating the processing of follow-up sludge.
10. a kind of drying means of sludge heat drying system according to claim 7, it is characterised in that:In the step It is rapid 1) in, the sewage discharged from the leaking hole of dehydration tube, will successively by the double filtration of the first screen pack and the second screen pack The granule foreign filtering of sewage, consequently facilitating the processing of later stage sewage is recycled.
