Description

[Detailed Description of the Invention] The present invention relates to a fermenter for fermenting raw livestock manure such as chicken manure, cow manure, pig manure, etc.

Livestock manure, especially chicken manure, is especially used as fermented manure for field crops. Many processing apparatuses have been proposed and put into use for producing fermented manure.
This invention takes into consideration the fermentation tank, which is particularly important among processing equipment, and allows the livestock manure on the fermentation bed to fall evenly downward from the radial line from the inner periphery to the outer periphery of the fermentation bed. The problem was solved and the result is shown here.

The feature of the livestock manure fermentation tank of the present invention is that the fermentation bed inside the closed fermentation tank has a discharge port that becomes wider from the center toward the outer periphery, and the lower surface of the discharge port is movable from the center of the fermentation bed to the outer circumference. A closing tongue piece 13 is provided, and the closing tongue piece 13 has a shape similar to the discharge ports 11 and 12, that is, it is wide from the center toward the outer periphery, and the discharge conveyor is connected to the lower part of the discharge port provided in the fermentation bed at the bottom of the fermenter. The fermented excrement that falls through the slit between the discharge port and the closing tongue is discharged by a conveyor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to illustrative drawings.

Figure 1 is a partially cutaway front view of the livestock manure fermentation tank.
FIG. 2 is a plan view of the same. This fermenter has two fermentation chambers, an upper fermentation chamber 2 and a lower fermentation chamber 3, which are obtained by dividing the fermenter main body 1, which has an insulated and sealed structure, into upper and lower halves. A heat exchanger 4 for heating at the initial stage, an exhaust port 5, and an input port 6 for inputting livestock manure are provided. In the fermentation chamber, a rotary cylinder 9 is provided penetrating through the center of two upper and lower fermentation beds 7 and 8, and a stirring blade 10 for stirring livestock manure is attached to the rotary cylinder 9.

Temperature-controlled air is supplied to the stirring blades 10 from the heat exchanger 4 via the rotating cylinder 9. Stirring blade 1
Since the air is blown out from the air outlet 18 provided at 0, the livestock manure being fermented is both temperature-adjusted and dried. The upper and lower fermentation beds 7 and 8 are provided with discharge ports 11 and 12 each having a shape that becomes wider from the center toward the outer periphery, as shown in FIG. A closing tongue piece (damper) 13 is clamped so as to be movable from the center toward the outer circumference. When this closing tongue piece 13 is pulled from outside the fermenter, a slit 14 is formed as shown by the two-dot chain line in FIG. These slits are formed almost uniformly from the side of the fermentation bed toward the rotating cylinder to the outer circumference. Therefore, livestock manure can be dropped almost evenly along the radial line from the inner periphery to the outer periphery of the fermentation bed.

Discharge port 12 of the fermentation bed 8 provided at the bottom of the fermentation tank
A U-shaped casing 15 is provided below as a discharge conveyor, and a screw conveyor 16 is installed therein.
has been set up. By disposing this screw conveyor 16, when the fermented manure falls from the discharge port 12, it is broken down by the screw conveyor into small particles, and then sent to the take-out port 17.

With the above structure, the livestock manure that has been fermented for a predetermined time in the upper fermentation chamber is passed through the closed tongue piece 13.
By pulling it open, a part of it falls evenly from the inner periphery to the outer periphery into the lower fermentation chamber, where it is re-fermented and dried for a predetermined period of time, and then dropped onto the screw conveyor, where it collects small particles. It is extracted as fertilizer.

As described in detail above, this invention uses a slit open method to allow livestock manure to fall to the bottom for fermentation and discharge, eliminating the need for tiering caused by the opening and closing of the damper as in the conventional method. complete evacuation is possible. . In addition, the product falls evenly from the fermentation bed (evenly from the inner circumferential side to the outer circumferential side). Furthermore,
A wide slit opens even with short strokes of the closing tongue. Therefore, the difficulty of movement due to clogging with excrement that occurs when the sliding portion is long, and the amount of drawing out to the outside of the tank main body are reduced, so that it does not get in the way of the operator. On top of that, there is a floor surface and a discharge port 1.
Since there is no difference in level between 1 and 12, the surface is flush with the floor, and therefore uniform fermentation can be expected.

As a result of the above effects, livestock manure can be used as high-quality fermented livestock manure that has been properly fermented and dried and has homogeneous, small particles.
