Description
Technical field
The present invention relates to a kind of device for solid waste being carried out anaerobic fermentation process, belonging to anaerobic fermentation technology
Field.
Background technology
Anaerobic fermentation is one of effective way processing organic solid castoff, and garbage is under anaerobic by micro-life
The metabolic activity of thing and stabilized.Anaerobic fermentation is generally carried out in anaerobic fermentation tank, and anaerobic fermentation tank is the life of microorganism
The excellent condition of long offer, meets growth and the breeding of microorganism.In anaerobic fermentation tank, these its catalysis or the oldest of biological performance
The function of metabolism.Owing to can not there be dissolved oxygen, so need not stirring at a high speed in anaerobic fermentation tank, even if stirring the most only plays mixing
Effect.Also can be passed through nitrogen etc. in anaerobic fermentation tank, but operating cost can be improved.
Anaerobic fermentation tank is not suitable for viscosity compared with big or that solids content is big occasion, because so solid material is at fermentation liquid
Interior skewness, mass transfer effect is the best.To this end, be also equipped with agitating device in some anaerobic fermentation equipments.
Chinese patent literature CN104893958A discloses one " organic waste high-temperature dry-type anaerobic ferment devices ", including
Hydrolysis acidification case and horizontal anaerobic fermentation tank, be provided with auger propeller in anaerobic fermentation tank.But this auger
Angle of rake effect is to advance material by anaerobic fermentation tank feed end to drainage conduit, it is achieved the intermittent feeding of installation for fermenting, continuously
Work and automatic discharge, complete a fermentation period, and material is simply stirred in progradation, and stirring only plays the work of mixing
With, mass transfer is had little to no effect.
A kind of " dry type anaerobic fermentation system " disclosed in CN105647793A, including the feed arrangement being sequentially connected with, anaerobism
Installation for fermenting and drawing mechanism, anaerobic ferment devices includes anaerobic fermentation tank and Monitoring and Controlling mechanism, sets inside anaerobic fermentation tank
Agitating device, agitating device is had to include the many shafts being arranged side by side from fermentation tank charging aperture to discharging opening successively and oar thereof
Leaf, agitating device realizes the stirring successively that many shafts move in circles under the control of Monitoring and Controlling mechanism.Although this system
Realize the stirring successively that many shafts move in circles, adapt to the fermentation process of high impurity material, but this system is by stirring
Mix and reach material conveying and heat transfer (seeing its description the 0027th section).
Anaerobic fermentation tank in above two anaerobic fermentation equipment is all horizontal, and its internal agitating device is mainly used in
Conveying material, does not make solid material being sufficiently mixed in fermentation liquid, and mass transfer is not violent, is not particularly suited for viscosity relatively
Big or that solids content is big fixed-end forces.
CN102952746A disclosed " a kind of anaerobic fermentation tank ", including a tank body and multiple agitator, these agitators
All include a rotary shaft and be positioned at the agitator arm of this rotary shaft one end, the other end of each rotary shaft all with the inwall of this tank body
One join domain in face fixes connection and the axis of each rotary shaft has angle with the normal of this join domain.This fermentation tank leads to
Crossing the form that the normal of join domain that this rotary shaft is arranged to be secured to connect has angle promotes fermentation liquid to form edge
The axial tumble mixed of tank body and/or form the fermentation liquid tumble mixed along tank body radial direction, therefore improve solid material
Distribution consistency degree in fermentation liquid.Agitator in this fermentation tank mainly stirs fermentation liquid, makes fermentation liquid along tank body footpath
To local tumble mixed, it is impossible to enough form overall disturbance from bottom to top in tank body, therefore, the relatively big or solid for viscosity
The solid waste that content is big is also inapplicable.Simultaneously as rotary shaft is installed on the internal face of tank body, manufacture difficulty is relatively big and keeps in repair
Inconvenience.It addition, tank base cannot obtain being sufficiently stirred for of agitator, and it is frequently present of the raw material caused because stirring is uneven
Depositional phenomenon.
Need badly at present and a kind of can efficiently process the viscosity anaerobic fermentation compared with big or that solids content is big solid waste
Equipment.
Summary of the invention
The present invention is directed to the deficiency that existing anaerobic fermentation equipment exists, it is provided that a kind of volume yield rate is high, the suitability is strong, dimension
Protect the highest solid circulation anaerobic reactor.
The solid circulation anaerobic reactor of the height of the present invention, employing following technical proposals:
This device, including tank body and at least one turn over and copy unit, each turns over copies unit and is arranged in tank body；Described turning over copies list
Unit includes drivewheel, actuating device, bearing and follower, and actuating device is arranged on the top of bearing, and actuating device is provided with
Guide cylinder, the upper and lower of guide cylinder is respectively arranged with discharging opening and charging aperture, and drivewheel connects with the outfan of actuating device
Connecing, follower is arranged on bearing bottom, and connecting between drivewheel and follower has transmission band, drivewheel, follower and transmission band
It is placed in guide cylinder, is distributed on transmission band and turns over duplicate.
Copy unit offer an installing hole corresponding to each turning on the top cover of described tank body.
The sewage outfalls setting of described tank body is at the relative side bottom of the dog-house of tank body, to prevent charging from " short-circuit " occurring
Phenomenon.
It is provided with guiding cage, to install or to propose circularly enhancing disturbance unit turning over the periphery copying unit in described tank body
Time avoid mutual scratching.
The described duplicate that turns over is plate, dustpan shaped or bucket type.
Actuating device can use reductor or other device that drivewheel can be driven to rotate.
When said apparatus runs, starting each and turn over and copy unit, reductor drives drivewheel to rotate, and transmission band turns over duplicate
Drive the material (fermentation liquid and solids) in tank body to promote from the bottom to top, formed big inside and outside guide cylinder inside and guide cylinder
The circulation of amplitude ground is stirred, strong mass transfer and strengthening circulation, makes material mixing fully, and mass-transfer efficiency greatly improves.Certain turns over and copies list
Unit breaks down when needing repairing, and is proposed by tank body.
The present invention copies unit by arranging to turn in tank body, is promoted from bottom to top by the material in tank body and falls, makes thing
Material (including solid and fermentation liquid) forms entirety rolling disturbance in tank body from bottom to top, and the room that bottom is formed is rapidly by periphery
Material low level under stress supplements, and therefore, relatively greatly or solids content greatly (can be particularly well-suited to the viscosity such as muddy, high pasty state
Reach 20%) the fermentation process of solid waste, strong adaptability, scale can be realized and process；Simultaneously as turn over copy unit can
Installed by tank body top, it is possible to overall by proposing maintenance in tank body, facilitate manufacture and maintenance.It addition, tank body wall and bottom
Material have also been obtained and is sufficiently stirred for, and does not results in deposits materials phenomenon.
