Region is opened up with several filter openings 13, and 13 nested domain of corresponding filter opening is equipped with collection slag cylinder 3 outside desiccation cylinder 1, desiccation cylinder 1 and collection slag cylinder 3 it
Between form closed interlayer space, exhanst gas outlet 31, the bottom of collection slag cylinder 3 are offered on the top of collection slag cylinder 3 at high order end
The first slag notch 32 is offered in portion at low order end, the bottom of collection slag cylinder 3 is provided with conveyer belt along 3 axial direction of collection slag cylinder
33, conveyer belt 33 is docked with the first slag notch 32, helps deslagging.
It is just directly fallen from filter opening 13 from sieve pore 22 completely it should be noted that sludge is possible to undried, but
It is flowed directly into collection slag cylinder 3 without having to worry about the moisture of sludge, because the structure of sludge itself determines that moisture therein will not analyse
Go out, in addition the effect of high-temperature flue gas and high-temperature-hot-water, still can guarantee the drying property of 32 sludge of the first slag notch.
Hot water pipeline 4 is also equipped in interlayer space at the first slag notch 32, hot water inlet is provided on collection slag cylinder 3
41 and hot water outlet 42.In addition, in order to save dry required energy consumption, it is contemplated that the desiccation apparatus is used in combination with incinerator, will
Smoke inlet 12 is connected by the exhaust port of flue and incinerator, the heat exchange that hot water pipeline 4 passes through pipeline and incinerator
Device water tank connects, and the sludge of the first slag notch 32 discharge is sent directly into incinerator, has carried out the recycling of the energy, and prevent
Secondary pollution of the sludge in processing procedure.
It is blocked in view of the mode that existing desiccation cylinder 1 is directly fed be easy to cause feeding mouth 11, the present apparatus is by feeding mouth 11
Along the axial direction setting of desiccation cylinder 1, and pusher 5 is provided at feeding mouth 11, pusher 5 includes pusher cylinder 51 and positioned at pushing away
The screw charging ram 52 barrel 51 inside and be coaxially disposed with hollow rotating shaft 2, one end and the driving motor 53 of screw charging ram 52
Connection, the other end are extended to pusher cylinder 51 in hollow rotating shaft 2, its radial direction of 51 upper edge of pusher cylinder offers feeding port vertically
54, so that sludge can be effectively anti-blocking after screw charging ram 52 controls pan feeding.
In addition, unavoidable there are other rubbish impurity in sludge, these impurity still can not be from sieve pore after being dried
22 that are either discharged in filter opening 13 and will certainly be formed in the low order end of hollow rotating shaft 2 or desiccation cylinder 1 accumulate, therefore in desiccation cylinder 1
Low order end at offer the second slag notch 14, corresponding second slag notch 14 offers mud hole 23 on hollow rotating shaft 2, for fixed
The large volume impurity that phase discharge can not be filtered through sieve pore 22 and filter opening 13.
It remarks additionally, sieve pore 22, filter opening 13, the size of mud hole 23 and the position in the device are needed by specific actual use
It is arranged.Mud hole 23 generally may be disposed at the low order end of hollow rotating shaft 2, and a circle is opened up along the curved surface of hollow rotating shaft 2, can
To be arbitrary shape hole.What the position of sieve pore 22 and filter opening 13 considered first is at sludge and high-temperature flue gas most high efficient heat exchanging two
Person is distributed in respectively on the periphery of hollow rotating shaft 2 and desiccation cylinder 1, and 22 size of general sieve pore is more than 13 size of filter opening, can be by
The mode of size gradation is arranged, and the other manners such as interval mode or random mode can also be arranged by size.

In to sludge carry out first drying, by the high-temperature-hot-water that tail gas from incinerator heat exchange obtains be passed through hot water pipeline 4 to sludge carry out
Secondary drying, the sludge after the desiccation that the first slag notch 32 is discharged are sent into incinerator burning, realize that high efficiency of energy utilizes, save
Energy consumption.And high-temperature flue gas is exchanged heat with the sludge in desiccation cylinder 1 using convection type, drying is more efficient.
Specific workflow：
Sludge is entered by the feeding port 54 of pusher 5, is pushed into the hollow rotating shaft 2 of desiccation cylinder 1 through pushing spiral bar, dirty
The high-temperature flue gas entered at mud and the smoke inlet 12 of desiccation cylinder 1 carries out surface contact and carries out heat exchange, due to hollow rotating shaft 2
Constantly overturning drives sludge to be come into full contact with flue gas and accelerate desiccation speed, while the sludge after fine grained or desiccation
It is fallen into desiccation cylinder 1 by sieve pore 22 of the centrifugal force through 2 middle part of hollow rotating shaft, the spiral deflector 21 outside hollow rotating shaft 2 is to dirt
Mud is further ground so that sludge is fallen into through the filter opening 13 on 1 wall of desiccation cylinder on the conveyer belt 33 in collection slag cylinder 3, while sludge
Secondary heat exchange is carried out with the heat exchange hot water in hot water pipeline 4, finally, the sludge of desiccation is sent to first by conveyer belt 33 and slags tap
Mouth 32, and flue gas is discharged after exchanging heat with sludge by the exhanst gas outlet 31 through sieve pore 22, filter opening 13 to 3 top of collection slag cylinder.
In conclusion the high temperature cigarette that the mud drying device in the present embodiment is generated by device cooperation using incinerator
The high-temperature-hot-water that gas and exhaust gas heat exchange dries sludge twice, and obvious drying effect effectively reduces the moisture content of sludge,
The energy consumption for reducing dehydration, makes full use of and has saved the energy, and secondary pollution generation is avoided in drying process, can be extensive
Applied in the integrated treatment engineering of material desiccation and heat treatment.
