Description
Technical field
The present invention relates to sludge pre-treatment techniques field, more particularly to a kind of bipacking-auger with preheating dehydrating function
Sludge conveyer.
Background technology
Sludge is the solid sediment matter as caused by water and sewage disposal process.The yield of present municipal sewage is drastically
Increase, while being increased to sanitary sewage disposal amount, the thing followed is the pressure increase of the processing for sludge；It is and dirty
The time of mud natural degradation is longer, and the sludge of early stage is not degraded, and new sludge has been stacked again, and sludge is for soil
Pollution can be produced with surrounding environment, if things go on like this, it will the ecological environment to city causes to have a strong impact on, and then limits city
Development.
Existing sludge treatment technique can be divided into following a few classes：（1）Sludge → concentration → pre-treatment（Add inorganic medicine
Agent, add organic medicament, freezing）→ dehydration（It is vacuum type, adding pressure type, centrifugal）→ aerobic sigestion → land decontaminating；（2）It is dirty
Mud → concentration → pre-treatment → dehydration → drying → land decontaminating；（3）Sludge → concentration → pre-treatment → dehydration → burning（Or
Thermal decomposition）→ ash content fills；（4）Building materials are done in sludge → concentration → pre-treatment → dehydration → drying → molten sintering →；（5）It is dirty
Fuel is done in mud → concentration → pre-treatment → dehydration → drying →；（6）Sludge → concentration → anaerobic digestion → pre-treatment → dehydration →
Land decontaminating；（7）Sludge → concentration → evaporation drying → does fuel；（8）Sludge → concentration → wet oxidation → is dehydrated → filled out
Bury；（9）Sludge → concentration → temporary → high temperature dehydration → landfill, such as Patent No. 201310464982.5, it is entitled：It is a kind of

It is fixedly connected；3rd telescopic cylinder 43 drives the guide plate 46 to be moved forward and backward in the cavity of pressing plate 4.In order to keep away
When exempting from pressing plate the sludge in transfer pot is compressed, sludge can be flowed into the cavity of pressing plate, and the present invention is provided with and led
To track 45 and guide plate 46, pressing plate 4 is directed to plate 46 and moved forward so that be oriented to when sludge operation is compressed
The second hole 47 on plate and the first hole 41 on pressing plate carry out misclassification and come arrangement（Refer to Fig. 3）, such guide plate is just
The first hole 41, which can be blocked, prevents sludge to be flowed into the cavity in pressing plate；In pressing plate without compression, but heating component is entered
When row decline is stretched into transfer pot, it is directed to plate and is moved rearwards so that the second hole 47 on guide plate and first on pressing plate
On hole 41 is co-located（Refer to Fig. 2）, the U-shaped airway tube 72 in such heating component can pass through the first hole 41
It is extend into the second hole 47 in transfer pot and processing is evaporated to the moisture of sludge, it is worth mentioning at this point that, the present invention is led in U-shaped
When tracheae 72 is inserted in the sludge of transfer pot, the motor is controlled to open the globe valve and air exhauster, the steaming so distributed
Vapour can is discharged from discharge pipe 55, improves the efficiency of pre- thermal evaporation, and when pressing plate is extruded downwards, to close spherical
Valve, sludge is avoided to be overflowed from the opening of globe valve.
In the present invention, the left side of the transfer pot 1 is provided with a sewage sludge feed pipe 16, and sewage sludge feed pipe 16 and conveying
Tank connects.The sludge is flowed into transfer pot 1 from sewage sludge feed pipe 16, is carried out after dewater treatment is carried out by transfer pot
Conveying.The telescopic cylinder 62 of first telescopic cylinder 5 and second is erected at a support frame（It is not shown）On be fixed.Such
One telescopic cylinder 5 and the second telescopic cylinder 62 can carry out aerial fixation.The U-shaped airway tube and protective case use metal material system
Into the protective case is welded on the U-shaped airway tube.
In the present invention, the lower section of described two screw conveyors has a Storage water tank 58, it is described be filled with water on be provided with steel
Plate 59, water seepage hole is offered on the steel plate（Do not illustrate in figure）；Discharge outlet 60 is offered on the lateral wall of the Storage water tank.
In a word, transfer pot of the invention is provided with hollow cavity, toward hollow cavity in be passed through hot gas, to improve in transfer pot
Temperature, so as to can be also evaporated to the moisture in sludge；By being provided with a pressing plate and a heating component in transfer pot,
So when sludge is circulated into transfer pot, each heating component in framework is driven to carry out decline behaviour by the second telescopic cylinder
Make, heating component is contacted with sludge, so can be to dirt because the U-shaped airway tube in heating component is all to be passed through hot gas
Moisture in mud is evaporated, after heating component is detained a period of time, by the second telescopic cylinder by each in framework plus
Hot component carries out lifting operations, then is extruded the sludge in transfer pot pressing plate by the first telescopic cylinder, after extruding again
Start two screw conveyors, heating component is then subjected to step-down operation again, it is defeated due to the sludge after extruding, then by auger
Sending the upset of machine, now sludge water content can also infiltrate, then carry out secondary evaporation operation to sludge by heating component,
So operate, the moisture in sludge can be sufficiently dehydrated repeatedly, so as to reduce the moisture in sludge, after improving sludge
The treatment effeciency of sequence process.
The foregoing is only presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, it should all belong to the covering scope of the present invention.
