Description
Technical field
The present invention relates to a kind of sludge vacuum drying device.
Background technology
Municipal administration, prints and dyes, and the moisture percentage in sewage sludge produced after the sewage disposal of industry such as metallurgy is general all more than 80%, river course
The moisture content for the mud that desilting is produced is also all more than 80%, and at this moment the volume of sludge is big, and weight weight, transport is inconvenient, and this
The sludge of sample is utilized or landfill is all not all right, and must be cured to less than 60% by the moisture content of China's pertinent regulations sludge can just fill out
Bury.Current China is usually that moisture is extruded with filter press, the moisture content of sludge is reached less than 60%, then utilized or filled out
Bury.The advantage of filter press is technology maturation, simple to operate.But it also has many shortcomings,（1）Equipment volume is big,（2）Wet mud is needed
20% lime and 8%PAC (flocculant) are added,（3）The filter cloth of filter press is easily broken, and often to be changed,（4）The good dewatered sludge of press filtration
It need to manually remove, work under hard conditions（There is foul smell）,（5）Energy consumption is larger.
The content of the invention
The purpose of the present invention is that a kind of equipment volume is small to overcome the defect that prior art is present to provide, and energy consumption is low, holds
Easily realize the sludge vacuum drying device of automation mechanized operation.
The sludge vacuum drying device of the present invention includes sludge drying machine, wet mud warehouse, air heat exchanger, with air compressor machine
Connected air accumulator and the vacuum tank being connected with vavuum pump, described sludge drying machine include having in housing, housing several with
Countless micropores are distributed with the earthenware of housing diameter parallel, the tube wall of earthenware, have upper cover plate respectively in the above and below of housing
And lower cover, respectively there is the quantity identical hole coordinated with earthenware on upper cover plate and lower cover, in earthenware upper end and upper cover plate
There is O-ring seal on the contact surface in hole, on the contact surface of lower cover plate hole with there are sealing gasket, the dirt of wet mud warehouse in earthenware lower end
Mud outlet has pipeline to be connected with the upper end of housing, and pipeline is located at provided with the slide valve and air inlet for opening and closing pipeline, air inlet
At pipe nipple between the upper cover plate and slide valve of housing, air inlet is connected with the air outlet of air heat exchanger, there is two on housing wall
Individual hole, one of hole is connected with air accumulator, and another hole is connected with vacuum tank, has on the connecting pipe of housing and air accumulator
First ball valve, there is the second ball valve on the connecting pipe of housing and vacuum tank, and being located in the bottom of housing below lower cover has
With the rotating plate door of housing hinge, rotating plate door rotates by fulcrum of pin joint.
In the present invention, described housing can have random geometry cross section.
In the present invention, described slide valve can use oil cylinder pushing slide valve, and rotating plate door can use oil cylinder pushing rotating plate door,
First ball valve and the second ball valve can use electrical ball valve.
During work, the first ball valve and the second ball valve are first shut off, vavuum pump and air compressor machine is opened, vacuum tank is reached regulation
Negative pressure value, air accumulator also reaches defined malleation value.Sludge drying machine housing bottom, oil are closed using oil cylinder pushing rotating plate door
Cylinder promotes the connecting pipe of slide valve unlatching housing and wet mud warehouse, and wet mud enters sludge drying machine from warehouse of sludge, made
Wet mud is filled in each earthenware and pipe nipple.Now, the connection of housing and wet mud warehouse is closed by oil cylinder pushing slide valve
Pipeline, open the first electrical ball valve sludge drying machine is connected with vacuum tank, at this moment, enclosure interior and earthenware it is cylindrical between
The water for the wet mud that confined space is formed in negative pressure, earthenware is just sucked out outside earthenware, enters the storage of vacuum pot bottom
Deposit, meanwhile, the hot-air of air inlet pipe can be continuously replenished at pipe nipple, hot-air through sludge and heat sludge evaporate the water by
Siphon away, can thus accelerate the desiccation of sludge.Born through suction after a while, after sludge is cured to defined moisture content,
The first electrical ball valve is closed, while opening sludge drying machine housing bottom by oil cylinder pushing rotating plate door, the second electric ball is opened
Valve makes sludge drying machine be connected with air accumulator, and positive pressure air enters housing, close between at this moment enclosure interior and earthenware are cylindrical
Close space and be formed malleation, the micropore that positive pressure air can be through earthenware outside earthenware enters in earthenware, dewatered sludge
Earthenware bottom is extruded to siccative bucket.Meanwhile, positive pressure air can be by the superfine sludge blowback of negative pressure inspiration earthenware micropore
Storehouse in earthenware is gone back to, the blocking of earthenware micropore can be avoided.This is arrived, a workflow is just completed.The work of next flow
Work is exactly the step of repeating to chat.
The sludge vacuum drying device of the present invention makes the wet mud mud-water separation in earthenware using negative pressure, recycles malleation
Air returns the superfine sludge blowback for entering earthenware micropore and prevents from blocking in earthenware.The device designs ingenious, small volume, energy
Consumption is low, easily realizes automation mechanized operation.
