Air from solarization air cap outflow after, cached and merged in this space, make to be aerated it is more uniform, improve heap body fermentation effect
Fruit；
Wire netting is laid on aeration tube side on the net, and specification guarantees more than 18 mesh, in this way can will be more than a certain size
Fermentation material is blocked in above wire netting, is prevented fermentation material from falling into aeration pipe network and is caused aeration pipe choking in pipe network, influences to be aerated
Uniformity carries out influence ferment effect.
Specifically, the both ends of two aeration tubes are respectively air inlet and pipe plug, the both ends of the first aeration tube 20 are respectively
One aeration tube pipe plug 15, the first aeration tube air inlet 16, the both ends of the second aeration tube 21 are respectively the second aeration tube pipe plug 17,
Two aeration tube air inlets 18, the first aeration tube air inlet 16 and the second aeration tube air inlet 18 and the total inlet pipe in inlet duct
Total air inlet 19 on 5 is connected, and the bottom surface that total inlet pipe 5 passes through fermentation cylinder 2 is connected with blower, and total inlet pipe 5 is located at hair
Flowmeter 6 and valve 7 are additionally provided on pipeline outside ferment cylinder 2, since the air quantity required for the different phase of fermentation is big
It is small also different, therefore, is controlled by air force of the valve 7 to the generation of blower 8, make the air quantity shown in flowmeter 6
Within the scope of the best air force in size stage locating for it, it can just guarantee that the ferment effect of the installation for fermenting is ideal.
When heap body after fermentation, carries out draw operation by discharge port 3, discharge port 3 includes first in installation for fermenting
Discharge port and the second discharge port, two discharge ports are symmetrically distributed in the side wall surface of fermentation cylinder 2, and tunning is in discharging process
In simultaneously from two discharge hole for discharge, not only accelerate discharging speed, also make tunning be discharged to as far as possible fermentation cylinder 2
Outside, the tunning residual fermented in cylinder 2 is less, is conducive to the progress fermented next time.
Entire fermentation workflow are as follows:
Two discharge ports 3 for being located at the side wall of fermentation cylinder 2 are closed, by municipal sludge or feces of livestock and poultry and rice chaff or rice
Shell etc. is tentatively mixed in proportion on ground, reaches the optimum of aerobic fermentation, the hair that then will tentatively mix
Ferment object is poured slowly into fermentation cylinder 2 from feed inlet 14 and is sufficiently mixed, and aerator and agitating device is opened, to fermentation material
It is stirred, uniformly rear closing agitating device to be mixed, then adjusts the valve 7 in aerator, air quantity is transferred to fermentation first
Within the scope of the best air quantity in stage；
At the end of the first stage of fermenting, air quantity is adjusted to required air force, agitating device is opened, since fermentation produces
Raw heat can generate vapor to internal, and under the action of stirring and aeration, the intracorporal vapor of heap will be from fermentation cylinder
The top discharge heap of body 2 is external, in addition, stirring can be such that tunning is uniformly mixed and improve heap body porosity, under being conducive to
Agitating device is closed in the fermentation in one stage, air quantity is adjusted again into the best air quantity of place fermentation stage, Mei Gejie
Section all repeats above operation；
Continuously ferment 4 step left-rights in this way, and fermentation period is 16 days or so, and entire fermentation process terminates, by air quantity tune
Required air force is saved, agitating device is opened, opens the discharge port 3 of fermentation 2 two sides of cylinder, tunning is discharged.
The present invention efficiently reduces the loss of heat in fermentation process, is conducive to the raising of heap temperature, shortens fermentation week
Phase；Agitating device with screw blade can be such that material is sufficiently mixed, and improve the porosity of heap body, guarantee next stage
The abundant progress of aerobic fermentation；Compensation piping mode makes to be aerated more uniform, reduces anaerobic fermentation region, makes organic solid
Waste aerobic fermentation is more abundant, promotes ferment effect.
It is to be appreciated that describing the skill simply to illustrate that of the invention to what specific embodiments of the present invention carried out above
Art route and feature, its object is to allow those skilled in the art to can understand the content of the present invention and implement it accordingly, but
The present invention is not limited to above-mentioned particular implementations.All various changes made within the scope of the claims are repaired
