The main body 100 applied to the present invention includes a circular tank 120, an air injection hole 140 perforated in the tank, and a branch plate 160 provided below the air injection hole.

The tank 120 is basically based on a circular shape, but in some cases, may be arbitrarily produced according to the site conditions, the type of waste, the input amount of the fermentation apparatus 10 of the present invention, such as square, polygon. Of course, the material is steel or non-ferrous metals are optionally used.

The fermentation chamber 122 provided inside the tank 122 is divided into upper and lower portions by the partitioning means 300 to be described later, and is composed of a primary fermentation chamber 122a of the upper portion and a secondary fermentation chamber 122b of the lower portion to ferment the primary fermentation. After that, the fermentation is completely performed in the secondary fermentation chamber 122a.

The air inlet 140 is perforated on the wall surface of the tank 100 to inject the air required for fermentation, and the air inlet pipe connected to the compressor is inserted therein to supply air.

The branch plate 160 has a "∧" shape as shown in the figure so that the air injected from the upper portion and the waste supplied from the supply portion are evenly dispersed to prevent the waste from accumulating at any specific position and the air is dispersed. This is the configuration that allows it.

Supply unit 200

The supply unit 200 supplies the food waste, sewage sludge, and livestock waste to make compost and decomposed soil into the tank 120, and to the hopper 220, the supply screw 240, and the distribution plate 260. It is composed.

The supply screw 240 has a configuration in which both sides are different from each other with respect to the center, that is, the screw directions are opposite to each other, so that the center portion is inserted into the lower portion of the hopper 220 so that the waste supplied from the hopper 220 is transferred to both sides. To be distributedly supplied.

On the other hand, each of the lower end of both ends of the supply screw 240 is provided with an inlet 262 is supplied into the fermentation chamber 122 through this, the distribution plate 260 is provided under the inlet 262.

The distribution plate 260 is configured in the same manner as the branch plate 160 described above, and is configured to allow the waste to be supplied along the inclined both side plates.

Partition means 300

In the present invention, the partition means 300 has two functions.

First, the fermentation chamber 120 is partitioned so that it is divided into a first fermentation chamber 122a and a second fermentation chamber 122b so that the wastes supplied from the supply unit 200 are fermented for a predetermined time in the first fermentation chamber 122a. In this case, the fermentation is completely performed by putting it into a second fermentation chamber.

Of course, the second fermentation chamber 122b may be blocked from the outside by the partitioning means to improve the fermentation effect by maintaining the internal temperature at all times.

Another function of the partitioning means 300 is to regulate the amount of supply.

In other words, in order to ferment waste, it is a certain temperature and time, and a supply amount corresponding to the temperature. In the present invention, the partition means 300 is to improve the effective fermentation and efficiency by adjusting the supply.

To this end, the partition means 300 of the present invention is composed of a porous plate 320 and the opening and closing plate 340.

The perforated plate 320 located in the upper portion is provided with an outlet 322 at equal intervals, the outlet 342 is also formed in the opening and closing plate 340 at the same interval to push and pull the opening and closing plate by the cylinder 380 If these outlets and outlets coincide in the process, waste is introduced into the second fermentation chamber 122b.

In other words, when the waste flows through the supply unit 200, the partition means 300 has an upper surface in a state in which the outlet 322 and the outlet 342 cross each other to seal the second fermentation chamber as shown in FIG. 7. To accumulate waste.

In this state, when the cylinder 380 passes through the opening and closing plate 340 after the predetermined period of time, that is, after the first fermentation, the waste flows into the second fermentation chamber 122a.

At this time, the push rod 360 which is erected on both sides of the outlet 342 allows the waste to be pushed to the outlet so that it can be smoothly discharged.

Here, the sensor 500 is installed in the fermentation apparatus of the present invention.

This sensor is for controlling the inflow of the waste introduced into the first fermentation chamber (122a), if a predetermined amount is more than a predetermined amount of flow by stopping the screw 240 of the supply unit 200 so that no more inflow, This prevents the fermentation effect from dropping.

In addition, the partition means of the present invention is composed of a pair of left and right as shown in the figure, but in some cases can be further subdivided. In this case, there is an advantage that the capacity of the cylinder is reduced and there is no risk of failure.

Stirrer 400

The stirrer 400 installed in the lower portion of the second fermentation chamber has a configuration in which a blade 420 is provided in a radial direction on a main shaft connected to the motor 440, and transmits power of the motor through a chain transmission 460 to the blade. Rotate to prevent waste from clumping or sticking to walls.

Reference numeral 600 in the figure is a control unit.

Next, the operation process of the present invention having the above configuration will be described.

First, the waste is introduced into the hopper 240 of the supply unit 200 and flows into the first fermentation chamber 122a through a screw 220 installed under the hopper. At this time, the waste is dispersed along the distribution plate 260 and evenly distributed inflow into the first fermentation chamber (122a), the porous plate 320 and the opening and closing plate 340 of the partition means 300, that is, the outlet and the outlet They are interlocked with each other.

When a predetermined amount is input and the operation of the screw is stopped by the sensor 500, fermentation starts while air is injected into the first fermentation chamber 122a through the injection hole 160.

After a predetermined time, the controller 600 operates the cylinder 380 of the partitioning means 300 when the time and the temperature sensed by the sensor are in accordance with the previously input data. The first fermented waste is introduced into the fermentation chamber so that the second fermentation takes place.

Here, the cylinder 380 pushes the opening and closing plate to introduce waste into the second fermentation chamber, and when the inflow is completed, the cylinder 380 is pulled again to seal the second fermentation chamber.

At the same time the second fermentation chamber 122a is sealed, the screw 220 of the supply unit 200 provided on the tank 120 is operated to allow the waste to be reintroduced.

The waste into which the second fermentation chamber 122a flows starts fermentation with air injection, and the stirrer 400 rotates by the motor 440 to stir the waste and fermentation.

After the second fermentation, the composted waste is transferred to the discharge screw 480 and flows out through the exhaust port 482.

As described above, the fermentation apparatus of the present invention is classified into primary fermentation and secondary fermentation so that the waste can be completely composted, in particular, the second fermentation chamber is sealed so that the temperature can be maintained, and also the specification of the tank at all times. In accordance with the present invention, an appropriate amount can be introduced.
