Using a kind of drying means of sludge heat drying system as described above, comprise the following steps：
1) water process is gone at the beginning of sludge：
Sludge is transported in dewatering cavity 1 first and carries out dewater treatment, sludge is entered in dehydration tube 3 from feed hopper 36,
Pressurizing unit is started working, and it is crowded that extruding cylinder 16 drives stripper plate 17 to be compressed the sludge in dehydration tube 3 by piston rod
Pressure processing so that the sewage in sludge is drained into the bottom of dewatering cavity 1 from the leaking hole 15 in the lower wall of dehydration tube 3, then the bottom of from
The discharge outlet discharge in portion carries out focusing on for sewage, the sewage discharged from the leaking hole 15 of dehydration tube 3, successively by the first mistake
The double filtration of the screen pack 14 of filter screen 13 and second, the granule foreign of sewage is filtered, consequently facilitating the processing of later stage sewage is again
Utilize, while while stripper plate 17 is compressed extrusion process to sludge, the crushing tooth 18 of the bottom surface of stripper plate 17 is by sludge
Hard particles crush, can not only improve the dewatering efficiency of sludge, and stripper plate 17 can be protected again；
2) sludge decentralized processing：
(1) right-hand member of sludge from the dehydration tube 3 after the dewater treatment of dehydration tube 3 enters the tilting table 4 of scattered chamber 2
On, while dispersal device is started working, decentralized processing, electric rotating are carried out to the sludge on tilting table 4 by multiple dispersal devices
Machine 20 drives the rotation of scattered axle 21, so as to drive the rotation of dispersion impeller 22 to carry out decentralized processing to extruding blocking sludge, no
Only so that the blocking sludge after extrusion process is ground into graininess, it is easy to the drying and processing of follow-up sludge, and can improve again
The dispersion rate of sludge, accelerates the processing speed of sludge so that the sludge quality of subsequent treatment more preferably, slows down drying box 7
Operating pressure；
(2) while periodically carrying out washing and cleaning operation to dispersal device, moved down, shortened by disk 24 is cleaned by expansion link 23
The distance between disk 24 and dispersal device are cleaned, then the water in water tank 26 is transported to from elastic delivery pipe 25 by back suction pump stretched
In contracting bar 23, enter finally into cleaning disk 24 and sprayed away from cleaning disk 24 bottom surface, 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 7 by the transmission of conveyer belt；
(2) before sludge enters drying box 7, the heater inside drying box 7 is preheated, heating plate 33
Internal heater strip 34 is heated, then is distributed by the thermal hole 35 on the surface of heating plate 33 so that the temperature in drying box 7
Reach the drying temperature of sludge；
(3) after sludge is entered in drying box 7, heater continuous heating carries out drying operation to sludge, stirred simultaneously
Mix device and operation is stirred to sludge, increase the surface area of sludge so that heat is fully contacted with sludge, so as to improve sludge
Drying effect and quality；
(4) dried sludge passes through the cushioning effect of elastic buffer plate 8, and further the drying time of extension sludge, makes
The drying effect for obtaining sludge more preferably, enters back into mud-output trough 12, discharged from mud-output trough 12.
4) cleaning is repaired with checking：
Periodically the inside of the inside of dehydration tube 3, screen pack and drying box 7 is cleared up and repaired, by it is viscous stick it is residual
Remaining sludge and impurity are removed, consequently facilitating the processing of follow-up sludge.
The specific embodiment of the present invention is these are only, but the technical characteristic of the present invention is not limited thereto.It is any with this hair
Based on bright, to realize essentially identical technique effect, made ground simple change, equivalent substitution or modification etc., all cover
Among protection scope of the present invention.
