Put and method.Present invention is generally directed to sludge slurry sludge cake after mechanism filter-pressing is dehydrated, then be dried and be squeezed into granular powder
Shape.
Background technology
China walked the control paid attention to all kinds of sewage sludges then in recent years, but took up an area owing to Dredged Sludge exists to stack
Area is big, mummification speed is slow, have the problems such as pollution to environment, even if developed country nearly 2 years is also that the mud of dehydration is embedded in soil
In have no better method appearance, illustrate that the treating sludge technology of developed countries does not the most break through.And it is domestic especially it
Key scientific and technological projects as " 13 ", it is therefore desirable to find a kind of novel process technique.Through retrieval, Chinese patent
201010252412.6 disclose " a kind of sludge granulation dryer and method ", and this invention is by screw extruding bri quetting granulation machine
Mud is cut into granule by screw extruding by shaping aperture plate and rotating blade and enters spouted fluidized bed.But we are in examination
Testing middle discovery, the viscosity of dried mud is the least, is hardly formed bulk, and processes mud by shaping aperture plate, and flow is limited
System, is difficult to improve the treating capacity of mud.And the energy that consumes of mode that its hot blast processes is the highest, it is unfavorable for reducing cost.
Typical screw rod is generally divided into feeding section, compression section, metering section.Feeding section enters barrel pipe not for conveying from feed arrangement
The bulk material of polymer of fusing, press to barrel squeezed with polymer is compressed for compensating shelves polymer in bulk in compression section
The volume-diminished produced during inwall, metering section is for pushing away the front discharge end to extruder the polymer of fusing.Thermoplasticity is moulded
The extruding pelletization of material has been highly developed technique, and the sludge cake that various sewage sludge is after mechanical dehydration, due to wherein
The component of mud is complicated, and variability is big, and composition body is that in water, suspended solid forms through the cementing cohesion of different modes, structure pine
Dissipating, in irregular shape highly non-uniform, specific surface area is high with space, has fractal structure, has similar fine hair in appearance
Branch and network structure, for the colloidal dispersion of stable existence, it is high that it is mainly characterized by moisture content.
Summary of the invention
It is an object of the invention to provide a kind of mud screw convection drying apparatus and method, mainly solve at existing mud

Detailed description of the invention
The present invention is further illustrated below in conjunction with embodiment
With reference to Fig. 1, a kind of mud screw convection drying device, including feed hopper 1, feed hopper 1 exit is provided with screw rod transmission
Device 2, screw conveyor 2 discharging opening faces toward screw extrusion electrical heating material drier 3 charging aperture, described screw extrusion electrical heating thing
Material dryer 3 is wrapped with electric heater 5, and the screw rod 13 of screw extrusion electrical heating material drier is passed through belt wheel driving by motor
Dynamic, screw extrusion electrical heating material drier top is provided with exhaustor 4 and is connected with negative pressure loading head 6, screw extrusion electrical heating thing
Material dryer outlet connects negative pressure loading head 6, and the outlet of negative pressure loading head is connected with cyclone separator 7 by pipeline, cyclonic separation
Device 7 is fixed on steelframe 14, and its lower end is provided with Blowing stopper 8 junctional complex feed bin 9, and the air outlet of cyclone separator 6 is by pipeline even
Connecing pulse dust collector 10, pulse dust collector 10 air outlet connects high pressure positive blower 11 and chimney 12 by pipeline.
The screw rod 13 of described screw extrusion electrical heating material drier is in entasis, and described screw rod 13 is main from length direction
Be divided into three sections, be feed zone 131 successively, changeover portion 132 and discharging section 133, the depth of threat of screw rod from feed end to discharge end by deeply
To shallow, smooth, then gradual change from shallow to deep.0.270-0.272 times of a length of spiro rod length L of described feed zone 131, is 6 teeth
Spiro rod section, the depth of threat of thread is shallow by being deep to, and screw diameter is transitioned into 0.055L from 0.034L；Changeover portion 132 is a length of for screw rod
0.36-0.37 times of length L, it is double thread structure that transition section length is 0.09-0.092 times of spiro rod length, prolongs in former pitch
0.130-0.136 times of long L is smooth section, sets 0.130-0.136 times of L again as double thread structure, changeover portion after smooth section
Terminate；0.22-0.23 times of discharging section 133 a length of spiro rod length L, screw diameter is transitioned into 0.034L from 0.055L；Discharging
The initial air outlet section 134 being provided with waistline hole of section, 0.018-0.019 times of air outlet section a length of spiro rod length L, discharging section is initial to be set
Having sudden change section, sudden change segment length is 0.037-0.038 times of spiro rod length L, and sudden change section screw diameter 0.055L suddenlys change and arrives
0.045L。
After driving, first electric heater 5 is heated to 80-90 DEG C, then the sludge cake after dehydration is given from screw conveyor 2
Enter screw extrusion electrical heating material drier 3 charging aperture, make sludge cake mixed before injecting screw extrusion electrical heating material drier
Closing uniformly, raw material enters screw extrusion electrical heating material drier and is threadingly advanced along with screw rod 13 direction, arrives described outlet
Raw material realizes the compression of trace before, is in granular form material to exit；By negative-pressure suction, i.e. divided by 11 whirlwind of high pressure positive blower
It is evacuated from device 7 entrance, causes the pressure exit much smaller than sludge cake granule of described cyclone separator 7 entrance.Due to
Be negative pressure, the most constantly have air to be supplemented in so that sludge cake granule can cool down rapidly thus fragility increases, simultaneously by
Pressure official post granule in pipe ends produces acceleration, and mud cake granule constantly clashes into tube wall, originally with the mud of adhesion
Cake granule can be departed from cleverly by this design, and the design of negative pressure is more beneficial for the recovery of impurity dust herein,
Cyclone separator 7 departs from the graininess material of adhesion and settles downwards due to action of gravity and enter material bin 9 by Blowing stopper 8, reclaims
Recycling, dust is then drawn into pulse dust collector 10 by high pressure positive blower 11, is discharged by chimney 12 after dedusting.
