Description

A drying machine of food refuse using quicklime}

The present invention relates to a device for drying food waste by using a phenomenon in which moisture and quicklime are chemically reacted with water and quicklime of the food waste by mixing moisture food waste with a certain ratio of quicklime to remove the moisture. Preferably, when a certain amount of food waste and quicklime are put into a mixer to be heated and mixed, the slaked lime becomes scattered by the chemical reaction of heat and quicklime to prevent the release of scattered slaked lime into the atmosphere and to dry the food waste with less calories. It relates to a food waste drying apparatus for.

Since food waste is 70 ~ 85% of waste, it is easy to ferment when a certain temperature is provided, and it is a general waste with high odor during fermentation process. It was difficult to have industriality due to the huge cost until it was processed, and there was a problem that the work could not be carried out due to severe odor and poor working environment in the processing process. When incineration of waste, extremely dangerous toxins such as dioxin are discharged, which makes it difficult to select an incineration site and to organize workers.

In consideration of the above problems, the present invention provides quicklime to the food waste dryer for selective use by drying the food waste and provides heat, but can dry the food waste with a small amount of heat, It is an object of the present invention to provide a device that can prevent the release of air caused by the scattering of slaked lime generated by.

It is characterized by consisting of a drain pipe 29 for discharging the water accumulated in (15).

Figure 1 is intended to be able to understand the whole of the subject innovation, Figure 2 shows the configuration of the subject innovation, Figure 4 is a detailed view of the settling tank.

The main body 11 has a mixing chamber 13 in which a stirring furnace 27 is formed, a combustion chamber 14 providing heat to the mixing chamber 13, and an upper portion of the main body 11 to operate the stirring furnace 27. A power supply, an inlet 28 through which food waste can be introduced, a gas discharge pipe 15 through which gas generated in the mixing chamber 13 is discharged, and a blower 12a for supplying gas from the gas discharge pipe 15. And the gas guide pipe 18 associated with the blower 12a are advanced to the combustion chamber 14 so that the gas in the mixing chamber 13 is combusted, as shown in FIG. Likewise, the gas discharge pipe 15 is equipped with a filter 21 that can be assembled and separated, and the gas guide pipe 18 of the combustion chamber 14 has a drain pipe 29 for discharging water generated by condensation. At the bottom of the main body 11, a food waste outlet 26 is provided which can unload the food waste of the mixing chamber 13.

The dust collecting chamber 17 is formed in association with the upper part of the exhaust pipe 19 of the combustion chamber 14, and the dust collecting guide 20 is connected to the dust collecting chamber 17, and the dust collecting guide 20 is connected to the blower 12b. The dust collection guide 20 linked from the blower 12b is connected to the sedimentation tank 22, and the sedimentation tank 22 has an inclined member so that the lower portion thereof is formed in a cone shape and the dust can be precipitated inside the cone. 25 is formed and the sedimentation container 22 receives water and the dust collecting guide 20 which has advanced into the water has a plurality of small holes 24 perforated around the end thereof.

Referring to the present invention as an embodiment,

The present invention is used to dry food waste by being provided with heat but mixing the quicklime with the trash to produce a quicklime of slaked lime by the water reaction of quicklime. When reacted with water, the resulting slaked lime is scattered into powder, so that the scattered powder is prevented from being released into the atmosphere through the combustion chamber.

When combustion starts in the combustion chamber 14, a certain amount of garbage and a certain amount of quicklime are introduced into the mixing chamber 13 of the main body 11 through the inlet 28, and the power is operated to rotate the agitator 27.

Since the food waste reaches 75 to 80% of moisture, since the food waste and quicklime are added together, the quicklime reacts with water and the reaction takes place when the stirrer 27 is operated.

In the combustion chamber 14, the calorific value is provided by combustion, so that the reacted quicklime and the remaining water is evaporated. Odor and harmful gases generated from food waste during evaporation are discharged to the gas discharge pipe (15).

The gas in the gas discharge pipe 15 is quickly discharged by the blower 12a associated with the gas discharge pipe 15 and the discharged gas moves to the combustion chamber 14.

When the slaked lime powder is scattered in the mixing chamber 13 by the above configuration, the slaked lime powder is moved to the combustion chamber 14 through the gas discharge pipe 15 like gas, and the gas moved to the combustion chamber 14 is Combustion and calcined lime is loaded into the combustion chamber 14 or part of the discharge to the exhaust pipe 19, so it is attached to the gas discharge pipe (15). Part of the slaked lime which is scattered by the filter 21 which is detachably mounted is filtered, and the unfiltered slaked lime powder is exhausted into the exhaust pipe 19 like the combustion gas and passes through the dust collecting chamber 17, and thus a part of the slaked lime powder. The sedimented lime powder which has been settled in the dust collecting chamber 17 and settled is discharged to a discharge tube (not shown).

The gas and the slaked lime powder of the dust collecting chamber 17 are forcibly exhausted by the blower 12b to which the dust collecting guide 20 is connected and are moved into the water of the cone-shaped sedimentation tank 22 through the dust collecting guide 20. .

Since the gas and the slaked lime powder moved by the dust collection guide 20 advancing into the water are discharged into the water through the small holes 24 around the end, the gas is released into the atmosphere without forming a large vortex in the water and the slaked lime is separated from the water. It mixes and precipitates, forming water and vortex.

As shown in FIG. 4, the cone portion of the sedimentation barrel 22 is formed with an inclined member 25 inclined at an upper portion and a lower portion thereof, and powder of slaked lime which is precipitated does not accumulate on the upper portion of the inclined member 25. If the bottom portion of 25, that is, accumulated in the cone portion of the sedimentation tank 22 and a predetermined amount is accumulated, it is possible to discharge the sediment with water by opening the drain pipe 29 and the sedimentation tank 22 when opening the drain pipe 29. If you replenish with fresh water), the water in the sedimentation tank 22 can always maintain the same amount of water. When the drying of the food waste is completed, the dry matter is discharged through the outlet 26. The configuration of the inclined member 25 is to prevent the vortices on the water from reaching the inclined surface below the inclined member 25 to prevent the sediment precipitated up by the vortex of the water.

The food waste drying apparatus according to the present invention is intended to prevent the release of the powder of slaked lime into the atmosphere when the slaked lime is generated, and to first precipitate the slaked lime powder of the mixing chamber by the filter, and to precipitate the secondary in the dust collecting chamber, It is effective in not causing air pollution by removing the slaked lime powder from the combustion gas exhausted from the drying device of food waste using both quicklime and heat by completely settling in the tradition.
