BACKGROUND ART [0002] Conventional organic composting apparatuses are known in which composting proceeds in a non-condensing manner. In this facility, only the lower air supply device exists when the raw materials are accumulated, and it is highly likely that the composting proceeds in the anaerobic state. In addition, the raw material is dispersed by using an agitator of the upper propeller type when the raw material is inputted, but the efficiency of the propeller becomes a problem due to the load of the raw material to be inputted, and the replacement is frequently occurred.

Also, during aerobic fermentation, active fermentation proceeds in the intermediate space portion of the fermentation tank. In this case, the anaerobic state often occurs, and a facility for eliminating it is needed.

Screw type is generally used for discharging after completion of composting, and in some devices, the distance between the screws is adjusted to discharge. However, under the fermenter, it is subjected to a lot of load and sometimes it causes the discharge device to fail.

In another aerated composting fermenter, two cylindrical blended fermenters are provided with two-stage boreholes, which are intermittently stirred with horizontal bar blades to prevent anaerobic conditions in the middle region of the fermenter. However, although the effect of preventing aggregation at the initial operation can be shown, the effect of increasing the amount of composting material accumulated in the lower portion of the bar blade at the time of continuous use is adversely affected, which promotes anaerobicization.

The body 110 has an inlet 112 through which the dehydrated solids can be injected into the upper portion and an outlet 114 through the lower side thereof. The discharge port (114) is connected to the quantitative discharger (160).

The dehydrated solids put into the raw materials are food waste. Livestock manure or the like is pretreated so that aerobic digestion can be smoothly performed through predetermined pretreatment and fixation. The pretreatment step may include a sorting step of filtering out foreign matter, a crushing step of crushing to a predetermined size, a sterilization step of sterilization at a high temperature, a dehydration step of controlling moisture content, and the like.

The bacteria glands 120 are provided on the upper part of the body part 110 to uniformly disperse the dehydrated solid material to be injected. That is, the dehydrated solid material introduced into the inlet 112 spreads horizontally evenly on the body 110 while being uniformly distributed. And the bacteria branch 120 is rotated by the driving motor M. [

It is preferable that the bacteria branch 120 has a function of detecting the input amount and stopping the input when an excessive amount is inputted.

A specific configuration of the bacteria branch will be described later with reference to Fig.

1, the upper air supply unit 130 is formed to connect both side surfaces of the body 110 in an upper portion of the body 110, and has an air injection hole in the periphery thereof, To the upper portion of the body 110. The upper air supply unit 130 connects both side surfaces of the body 110, and thus acts as a support for reinforcing the rigidity of the body 110.

As shown in FIG. 2, the central air supply unit 140 is formed so as to cross the front and rear surfaces of the body 110 in the central part of the body 110, To the center of the unit (110). In addition, the central air supply unit 140 is formed to be movable in the front-rear direction so as to supply air and prevent the contents filled in the inner space from being bundled.

The doser 160 serves to discharge the finished contents (compost) to the outside, and is provided at the lower part of the internal space of the body part to discharge the compost to the discharge port 114 side.

Conventional quantitative ejectors generally have a screw formed on the entire circumference of a rotary shaft. However, when the rotary shaft is formed as a screw, the frictional force is greatly increased.

In the meantime, the quantitative ejector 160 according to the present invention is provided with a screw 164 at a discharge axis 162 of a portion adjacent to the discharge port 114 so that quantitative discharge can be performed according to the rotation of the discharge axis 162 And the paddle 166 is provided on the discharge shaft 162 of the remaining part.

The paddle 166 has a small frictional force with the contents and has an effect of reducing the power required to drive the discharge shaft 162. [ Further, the paddle 166 has an excellent stirring efficiency of the contents as compared with the screw, so that the fermented compost can be prevented from being clumped or compacted, and as a result, the dischargeability can be improved.

The lower air supplier 150 is disposed around the quantitative ejector and serves to supply air to the lower contents. The present invention can be applied to the case where the lower air supplier 150 is disposed at the discharge shaft 162 of the quantitative ejector 160, Is provided at a portion where the end surface The air injected by the lower air supply 150 reduces the accumulation of contents around the discharge shaft 162 and secures a space between the contents to further reduce the power required to drive the discharge shaft 162 The effect can be. The specific shape of the lower air supply 150 will be described later with reference to Fig.

The bacteria branch 120 is horizontally rotated by the frame 122 being vertically coupled to the upper surface of the body 110. Accordingly, the dehydrated solids are uniformly dispersed and supplied horizontally in the inner space of the body part 110 by the germicidal branch 120. Thus, eccentricity of the organic material loaded on the body 110 can be prevented, air can be uniformly supplied, and high-quality aerobic compost can be produced.

In the illustrated embodiment, the quantitative ejector 160 includes a first ejection shaft 162-1, a second ejection shaft 162-2, a third ejection shaft 162-3, a fourth ejection shaft 162 -4).

Due to this movement, the contents above the discharge axis are disturbed and the contents of the upper part are mixed to ensure ventilation. At this time, the lower air supply unit 150 supplies air only around the operating discharge axis, thereby ensuring smooth discharge and ventilation, and producing high-quality compost.

As shown in FIG. 6, when the second discharge shaft 162-2 and the fourth discharge shaft 162-4, which are the even-numbered discharge shafts, are operated, the contents are discharged through the second discharge shaft 162-2 4 The contents of the upper part of the discharge shaft 162-4 are gradually moved downward as indicated by an arrow in the center. By alternately operating the discharge shafts, the layer of the contents is disturbed, And improve the quality of the discharge and contents (compost).
