The present invention relates to a fermentation system for treating organic wastes, which can make organic wastes into organic fertilizers by stirring, drying and fermenting organic wastes such as various food wastes with a fermentation agent for a predetermined time. It can prevent the heating and drying of organic waste efficiently and supply oxygen contained in fresh air to organic waste at the same time to complete fermentation in a short time. By the vanes, the organic waste in the fermentation tank is smoothly stirred and transported, so that the motor is not loaded, and the organic fertilized organic waste can be easily discharged.

As a conventional fermentation fertilizer maker is supplied with crushed food waste inside the fermentation tank as shown in Utility Model Publication No. 95-5245 (announcement date 1995. 7. 3), the burner and the motor are operated. The heat of combustion and exhaust gas are transferred to the fermentation tank through the barrier wall, and the heat of combustion and the exhaust gas flows into the inside of the fermentation tank through two indirect heat circulation tubes to raise the internal temperature of the fermentation tank. The rotating shaft inside rotates slowly at a constant speed by the rotation of the motor, and is attached to the rotating rotating shaft. The grinding knife of the shape grinds the food waste that is agglomerated into agglomerates, and the mixing knife of the I-shape with a ring is dried and fermented by the hot air inside while mixing the food waste, which is introduced into the fermentation tank. Exhaust gas and water vapor are known to be emitted by exhaust pipes.

However, in the conventional food waste fermentation fertilizer maker, the internal temperature of the fermentation tank drops more than necessary according to the discharge of steam, which lowers the fermentation efficiency extremely and eventually causes the fermentation time to take a long time and wastes energy. The organic waste and fermenting agent introduced into the fermentation tank are agitated by the stirring screw and the wing is formed in one direction on the stirring screw, so the organic waste is not driven to one side of the fermentation tank, which causes the stirring screw to be driven. Due to the overload of the motor, frequent failures occur, and the stirring efficiency is extremely low, and it is not enough to provide a high quality organic fertilizer, and when the fermented organic fertilizer is discharged, there is a problem of depending on natural dropping method and manpower.

The present invention is installed in the air inlet and air discharge hole formed on the fermentation tank to solve the above problems on one side to prevent the sudden temperature drop in the fermentation tank to efficiently carry out the heating and drying of organic waste At the same time, the organic waste is supplied with oxygen contained in the fresh air supplied from the air inlet to complete fermentation in a short time, and the stirring screw in the fermentation tank is fermented by vanes that are inclined in opposite directions to the transverse rods of the short and long ends. The organic wastes in the inside are subjected to smooth stirring and conveyance, so that an excessive load is not applied to the motor, and an organic fertilizer can be easily discharged.

The present invention for achieving the above object is described with reference to FIGS. 1 to 5 as follows.

In the drawings, reference numeral 19 is a pneumatic unit, and 20 is a control box. , 21 is a caster and 22 is a speed reducer.

Fermentation treatment for organic waste treatment according to the present invention is equipped with a fermentation tank (3) having a roughly cross-section U-shaped on the gas (2) consisting of a rectangular box body, the fermentation tank (3) The storage compartment 4 which consists of a double casing and can accommodate a heat medium in the middle of a double casing is formed.

An electric heater 5, which is a heating means for heating the heat medium, is installed in the storage chamber 4, and an inlet 7 in which an input door 6 is installed is installed at an upper portion of the fermentation tank 3, and a fermentation tank is provided. On the upper side of one side (3) to form a long inlet-type air inlet hole (8), the air inlet hole (9) is formed adjacent to the air inlet hole (8) is connected to the exhaust fan (10) Is installed.

Inside the fermentation tank 3, the stirring screw 12 that can be interlocked with the motor 11 in the transverse direction is laid out, the stirring screw 12 as shown in more detail in FIG. The vanes 14 and 14 'formed at the 13 and 13 are installed to be inclined in opposite directions to each other so that the organic waste is discharged by the vanes 14 and 14' when the horizontal bars 13 and 13 are rotated. The waste is transported to the opposite side of the outlet 15 and is disposed to be stirred, and organic waste is also discharged from the outlet 15 and the outlet 15 at the other ends of the rods 13 'and 13' installed at right angles to the horizontal rods 13 and 13. The vanes 14 " and 14 " are mounted to be inclined in opposite directions so as to be stirred and conveyed to the opposite side.

The outlet 15 is connected to the piston rod 17 of the air cylinder 16 is configured to be connected to the discharge shutter 18 that can open and close the outlet 15 while the slide operation.

Referring to the working relationship of the present invention configured as described above with reference to Figures 1 to 5 as follows.

After turning on the power of the motor 11 and the electric heater 5, which is a heating means, through the power switch attached to the control box 20, the organic waste and fermentation agent consisting of various food wastes are put into the inlet 7 As the stirring screw 12 inside the fermentation tank 3 rotates by the rotation of the motor 11, the electric heater 5 built in the storage chamber 4 of the fermentation tank 3 operates to heat the heat medium. Then, the organic waste such as food waste, which is put into the fermentation tank 3, is heated and dried while being stirred. And the organic waste and fermentation agent such as food waste put into the fermentation tank (3) and the horizontal bars (13, 13) of the long and short end attached to the stirring screw 12, rather than transporting the food residues in one direction as usual Food waste, etc. are caused by vanes 14 and 14 and vanes 14 " and 14 " attached obliquely to the longitudinal rods 13 ' The organic waste and fermentation agent of the mixture are mixed while being agitated and transported toward the outlet 15, and at the same time, the rods 13 'and 13' are installed at right angles to the horizontal rods 13 and 13 and the horizontal rods 13 and 13, respectively. The vanes 14 'and 14' and the vanes 14 '' 'and 14' '' installed to be inclined with each other are mixed with organic waste such as food waste and fermenter while being stirred and transported to the opposite side of the outlet 15. do.

That is, the mixed organic waste and the fermentation agent are agitated, heated and dried while having a circulation cycle transferred from the center side toward the outlet 15 at the center side and toward the outlet 15 at the outer edge, so that uniform fermentation is performed.

As described above, the water evaporated while the organic waste such as food waste is heated and dried is discharged out through the discharge hole 9 by the discharge fan 10 which is operated when the organic waste is raised to the upper portion of the fermentation tank 3, and at the same time, the air inlet hole. In (8), the fresh air from the outside is supplied in small amounts, and oxygen contained in the fresh air supplied in small amounts is mixed with organic waste such as food waste and fermentation agent to further promote fermentation.

The organic waste, which has been fermented through the above process, is transferred to the outlet 15 by vanes 14, 14, 14 " and 14 ", at which time the outlet 15 on the control box 20 is opened. When the switch is turned on, the pneumatic unit 19 is operated to operate the piston rod 17 of the air cylinder 16 connected to the left and right while the discharge shutter 18 slides open to the discharge port 15 to form an organic fertilizer. Waste is discharged through the outlet 15. In addition, the internal temperature of the fermentation tank 3 is checked by a thermistor or the like so that the discharge fan 10 is operated only when the temperature exceeds a predetermined temperature (temperature favorable for fermentation), and the fermentation tank is operated by operating the discharge fan 10 for a long time. (3) Prevent internal temperature from falling below a certain temperature and lowering fermentation efficiency.

The air inlet hole 8 and the air outlet hole 9 are formed at one side of the fermentation tank 3 so that the outside air introduced into the air inlet hole 8 is introduced into the lower side of the fermentation tank 3 to be sufficiently warmed. The fermentation tank (3) due to rapid inflow and discharge of air is discharged through the air discharge hole (9) by rising to the upper side with sufficient time with moisture generated when heating organic waste such as food waste. It is possible to prevent the rapid temperature decrease inside, and organic waste is heated and dried while contacting the fresh air supplied to the air inlet (8), such as food waste put into the fermentation process (1) in about 6-8 hours. The organic waste is completely fermented together with the fermentation agent, and the organic waste converted into organic fertilizer by fermentation is opened from the fermentation tank 3 by opening the discharge shutter 18 by the air cylinder 16. The organic waste, which has become an organic fertilizer, is easily withdrawn through the outlet 15.
