The course of work of multilayer aerobic fermentation system:
The present invention carries out working principle by taking the aerobic fermentation system that 4 layers of excrement sludge aerobic fermentation unit 19 form as an example
Illustrate, while be illustrated for air feed and air draft using blower B1501 and air-introduced machine B1502, while above two layers
Rabbling mechanism 20 is fitted in excrement sludge aerobic fermentation unit 19, upper two layers of installation bottom filter mechanism, lower two layers uneasy
Bottom filter mechanism is filled, two layers rabbling mechanism 20 is not installed down.
When work, excrement sludge is transported to the top of fermentation system by feed mechanism 17 first, excrement sludge (contains
Water is usually 85%-90%) enter in receiving hopper 1703, enter in auger conveyor 1702 through receiving hopper 1703, spiral transferring
Device 1702 is sent to deliver into excrement sludge in fermenting cellar 1, then rake material driving motor 1807 drives harrow frame by chain conveyer
1801 reciprocating movements uniformly import excrement sludge in fermenting cellar 1, it is noted herein that the bottom of harrow frame 1801 is high
Degree is above (being usually higher by 5 centimeters or so) of middle part filter 4 and edge filter 2, excrement sludge after upper complete material
Height is approximately the 2/3 of 1 height of fermenting cellar, while exhaust outlet 6 is arranged on 1 side wall of fermenting cellar above excrement sludge；Excrement is dirty
After mud enters fermenting cellar 1, since the surrounding of fermenting cellar 1, middle part and bottom are respectively equipped with the filter of filtering moisture, and then moisture
It can be flowed out by filter from discharge outlet, enter cesspool through drainpipe and be collected, while blender 2001 is in driving motor
Rotation is driven under the action of 2006, excrement sludge is sufficiently stirred, and avoids agglomerating because moisture is discharged, while blower B1501
Work, heated device 1510 heat, and will have certain temperature and air to enter air duct 5 through top layer's intake stack 9, from air feed
The gas outlet 502 of pipe 5 is discharged, and a large amount of air enters fermenting cellar 1 and excrement sludge carries out coming into full contact with carry out aerobic fermentation, mentions
High fermentation efficiency and effect, after the effect of first layer excrement sludge aerobic fermentation unit 19, the water content of excrement sludge is usual
60% or so；After fermentation after a period of time (usual 24 hours), drive rod 705 is driven by overturning driver 706
It is mobile, while driving hinge bar A704 that turnover panel 701 is pulled to be rotated by 90 °, and then form gap between two adjacent turnover panels 701,
Excrement sludge falls on next layer of excrement sludge aerobic fermentation unit 19 under gap and is further fermented, and rotates in turnover panel 1701
While turnover panel side wall push deflector 804, and then tilt down deflector 804, excrement sludge avoided to flow through deflector 804
Out, after the completion of blanking, turnover panel 701 resets, while under the action of reset spring 713, and deflector 804 tilts upwards, in turn
It can continue to export in water.Excrement sludge passes through aerobic fermentation layer by layer from top to bottom, in the last layer that the excrement fermented is dirty
Mud export, the water content of the last layer excrement sludge is generally 30% or so.The aerobic fermentation system advantage of the application is energy
It is enough that moisture is discharged layer by layer in time, (crushing) is stirred to excrement sludge, and quickly supply oxygen, and then improve aerobic hair
Ferment efficiency and effect.Fans B1501 as needed can carry out air feed to one layer of excrement sludge aerobic fermentation unit 19,
Can with a Fans B1501 simultaneously give multilayer excrement sludge aerobic fermentation unit 19 carry out air feed (by control switch 1509 by
One carries out air feed to every layer of excrement sludge aerobic fermentation unit 19), according to air-supply demand and blower B1501 when specifically used
Power carries out Rational choice；Similarly, an air-introduced machine B1502 can give one layer of 19 air draft of excrement sludge aerobic fermentation unit,
Can air draft be carried out to multilayer excrement sludge aerobic fermentation unit 19 simultaneously.
