Detailed description of the invention
Embodiment mono-
The dry method fermentation automatic circulating system of the present embodiment as shown in Figures 1 to 6, basic structure is: comprise that feed end top has charging aperture and discharge end bottom and have the fermentation storehouse 4 of discharging opening, the below in fermentation storehouse 4 is provided with the natural pond liquid collecting pit 26 being communicated with by drain-gate plate 25 with it. The top of fermentation in storehouse 4 is provided with the shower that two rows of the shower nozzle 23 that is intervally arranged are parallel to each other, and natural pond liquid collecting pit 26 is by being communicated with shower through the pipeline 24 of natural pond liquid circulating pump 27. The auger conveyor that two rows are parallel to each other and direction of rotation is controlled 7 that is extended to discharge end by feed end is equipped with in bottom in fermentation storehouse 4. The feed hopper 2 that bottom is provided with star-like removal device 10 is housed on charging aperture, and feed hopper 2 is positioned at the below of feeding conveyor 5 outputs. Discharging opening is equipped with able to turn on or off discharging opening baffle plate 32, and discharging opening baffle plate 32 is positioned at the top of outfeed belt conveyor 8 low sides.
Variable speed drives, auger conveyor list input gear dual output structure and the natural pond liquid circulated sprinkling system concrete structure of the star-like removal device transmission in feed hopper place, auger conveyor, respectively referring to Fig. 2 to Fig. 5, owing to being understood that, therefore no longer describe in detail with word.
It should be noted that, as shown in Figure 6, discharging opening baffle plate 32 down either side are supported on the rolling guide 34 of discharging opening both sides, tooth bar is equipped with respectively in discharging opening baffle plate 32 tops, both sides, form rack and pinion drive 29 with two in-line gears that are supported on discharging opening both sides, the gear shaft of two in-line gears is connected with the rotating shaft transmission of manual turntable 28 by worm gearing 31, the rotating shaft of this manual turntable 28 is in transmission connection by pulley arrangement 30 and the output shaft of drive motors 33, therefore discharging opening baffle plate 32 gets final product manual opening-closing, also can realize automatic open close by motor controlling cabinet 36.
When use, can carry out as follows:
The first step, startup feeding conveyor, star-like removal device, auger conveyor and natural pond liquid circulating pump, input by feeding conveyor and star-like removal device fermentation raw material from feed hopper, and under the stirring action of auger conveyor, be evenly distributed in fermentation storehouse;
Second step, after fermentation raw material is filled in the storehouse of fermenting, stop star-like removal device, keep feeding conveyor operation, thereby make feed hopper be full of fermentation raw material, play and make to ferment storehouse and extraneous seal isolation effect;
The 3rd step, maintenance auger conveyor and natural pond liquid pump operating cycle, continue upset fermentation raw material and spray the natural pond liquid that is derived from natural pond liquid collecting pit, fermentation raw material fully fermented, and form the circulation of natural pond liquid;
The 4th step, wait to ferment complete, close natural pond liquid circulating pump, open manually or automatically discharging opening baffle plate, start outfeed belt conveyor simultaneously, by conveying worm, the raw material after fermentation is outputed to outfeed belt conveyor from discharging opening and shift.
For further understanding, the present embodiment can be divided into charging, stir refining, natural pond liquid circulated sprinkling, discharging four systems, and it forms and the course of work is described below.
1) feed system:
When charging, hopper is filled to raw material, be transported to charging aperture by feeding conveyor, the star-like removal device being driven by drive motors, chain and sprocket driving device, gear-box speed changer is by the size of the material quantity in rotating speed control inputs fermentation storehouse. When charging finishes, first stop drive motors work, star-like removal device stall, now feeding conveyor is still normally worked, and raw material is constantly inputted and is delivered in charging aperture, in the time that charging aperture is full of raw material and covers the star-like removal device of charging completely, stop feeding conveyor work, the raw material being full of in charging aperture will play sealing function, cut off the space between fermentation storehouse and charging aperture, prevent in the storehouse in biogas leak outside with storehouse outside oxygen enter.
2) stir refining system:
Stirring even distributor in storehouse is two augers that longitudinally run through storehouse body, horizontally disposed, reasonable distance, liftoff certain interval, drive motors, pulley arrangement, gearbox drive auger to rotate, can obtain two augers in the same way or reverse rotation motion by the handle on gearbox, also different directions rotation separately, realize raw material motion, counterclockwise motion clockwise in storehouse, and produced simultaneouslyly turn over throwing. After raw material input operation and charging aperture sealing operation finish, first utilize the rotation of auger to abolish raw material surface crust phenomenon, and by the control of auger Different Exercise Mode, raw material is arranged in storehouse uniformly, for pretreatment preparation is carried out in the fermentation of raw material; Then open natural pond liquid circulated sprinkling system, rotate and raw material and natural pond liquid are fully contacted and fermentation reaction generation biogas by auger, also play simultaneously and increase mass-and heat-transfer function, make in storehouse raw material reaction even, improve factor of created gase, and the natural pond hydrorrhea being also beneficial in raw material goes out, enter natural pond liquid collecting pit by natural pond liquid pool drain-gate plate, enter natural pond liquid circulated sprinkling system.
3) natural pond liquid circulated sprinkling system:
The natural pond liquid that enters natural pond liquid circulated sprinkling system is extracted out in the liquid collecting pit of natural pond by pump, by natural pond liquid pipeline, natural pond liquid is divided into two-way, evenly spray the raw material in storehouse by shower nozzle, from raw material, overflow and again enter natural pond liquid collecting pit with the stirring through auger after raw material reaction, recycle.
4) discharge system:
Stirring under the acting in conjunction of refining system and natural pond liquid circulated sprinkling system, raw material is after the complete reaction of one-period, start drive motors, operating handle connects auger pulley arrangement and discharge baffle pulley arrangement, by the acting in conjunction of two augers, bottom material in storehouse is moved to discharging opening, drive motors by motor controlling cabinet control passes through baffle belt transmission device and speed change gear, drive taking rolling guide and open as the discharging opening baffle plate supporting, material (natural pond slag) is constantly discharged storehouse body. When discharge system is not worked, when discharging opening baffle plate is completely closed, material covers discharging opening baffle plate completely under the effect of auger, plays sealing function. Limited location switch in discharging opening, discharging opening baffle plate triggers limit switch in the time opening with complete closure completely, and motor stops driving the motion of discharging opening baffle plate, plays the effect of protection motor and baffle plate. For preventing accident, discharging opening baffle plate has turning handle can manually control the switch of baffle plate outward. The material of discharging storehouse body is entered the outfeed belt conveyor of below docking and is transported by it by discharging opening, and unified processing, there will not be pollution problem.
