1 is a perspective view showing a fuel manufacturing apparatus 100 using food waste according to an embodiment of the present invention, Figure 2 is a treatment unit of the fuel manufacturing apparatus 100 using food waste according to an embodiment of the present invention It is a diagram showing the arrangement of the processing plate 121' in 102, and FIG. 3 is a perspective view showing the conveying part 104 of the fuel manufacturing apparatus 100 using food waste according to an embodiment of the present invention.

1 to 3, the fuel manufacturing apparatus 100 using food waste according to an embodiment of the present invention includes a drying unit 101, a processing unit 102, a molding unit 103, and a transfer unit 104. ), and can be used to dry food waste and produce pellets in a state where it is mixed with sawdust. Here, the food waste may mean waste generated in the process of manufacturing food, food left after ingestion, and the like, and the pellet may have a cylindrical shape having a diameter and length of 2 mm to 5 mm. In addition, sawdust is a fine by-product generated as wood is processed and may exhibit a unique scent of wood.

The drying unit 101 may receive food waste and dry it. Here, the dried food waste may be generated as dry waste.

The drying unit 101 may be provided with an inlet 101a and an outlet 101b. Here, the inlet 101a may be formed on the upper surface of the drying unit 101, and the outlet 101b may be formed on one lower surface of the drying unit 101. Food waste may be supplied to the drying unit 101 through the inlet 101a and dried inside the drying unit 101. Dry waste, which is a food waste in a dried state, may be discharged from the drying unit 101 through the discharge port 101b.

In addition, the drying unit 101 may include a drying body 111 and a drying guide 113.

The drying body 111 is formed in a rectangular parallelepiped shape, and can be dried inside by receiving food waste. Here, the inlet 101a may be formed on the upper surface of the drying body 111, and the outlet 101b may be formed on one lower surface of the drying body 111.

The drying guide 113 is adjacent to one side of the drying body 111 and may be positioned in an up-down direction along one side of the drying body 111, and the top is positioned so as to be adjacent to the upper surface of the drying body 111, The lower end is positioned so as to be adjacent to the lower surface of the drying body 111.

In addition, the drying guide 113 may move the food waste in the vertical direction. In a state in which the food waste is located under the drying guide 113, the drying guide 113 may move the food waste upward. The food waste may be moved upward along the drying guide 113 to be positioned to correspond to the upper surface of the drying body 111 and may be supplied to the inlet 101a. That is, the drying guide 113 may be located on the upper surface of the drying body 111 so that food waste can be easily supplied to the inlet 101a.

The processing unit 102 is located spaced apart from the processing unit 102, receives the dry waste discharged from the drying unit 101, and classifies and discharges them by size. Here, the dry waste may be collected and stored in a storage container 200 different for each size after being discharged from the processing unit 102.

In addition, the processing unit 102 may include a processing housing 121, a processing driving unit 123, and a processing discharge unit 125.

The processing housing 121 may have a cylindrical shape. A processing space 102a may be formed inside the processing housing 121, and the processing space 102a may be formed in a cylindrical shape corresponding to the processing housing 121.

In addition, a plurality of processing plates 121 ′ may be located in the processing space 102a. Each of the processing plates 121 ′ has a circular plate shape, and may be positioned in parallel while being spaced apart from each other along the center of the processing space 102a. That is, the processing plates 121 ′ may be positioned along the vertical direction in the processing space 102a. Here, a plurality of processing openings 121a may be formed in each of the processing plates 121 ′. In particular, as the processing plate 121 ′ is positioned at the lower side, it may have a relatively small processing opening 121a.

Meanwhile, the processing space 102a may be partitioned to correspond to the number of processing plates 121 ′. For example, when there are three processing plates 121 ′, the processing space 102a may be divided into three, and the processing plate 121 ′ positioned at the top is spaced apart from the upper surface of the processing space 102a. The treatment plate 121 ′ located at the lowermost side may be positioned so as to be adjacent to the lower surface of the treatment space 102a.

The processing driving unit 123 is located under the processing housing 121 and may be connected to the processing housing 121. Here, the processing driving unit 123 may apply vibration to the processing housing 121 and may apply vibration to the processing plate 121 ′. In addition, the processing driver 123 may be connected to the center of the processing plate 121 ′ to rotate the processing plate 121 ′. The processing plate 121 ′ may be rotated about the center of the processing plate 121 ′ by the processing driver 123.

The dry waste may be put into the treatment space 102a and placed on the treatment plate 121 ′. As vibration is applied to the treatment plate 121 ′, a part of the dry waste passes through the treatment opening 121a and is guided to the treatment plate 121 ′ positioned at the lower side, and the remaining part of the dry waste is the treatment plate 121 ') can remain on the prize. As the treatment plate 121 ′ is rotated, the rest of the dry waste remaining on the treatment plate 121 ′ may be moved on the treatment plate 121 ′ toward the inner circumferential surface of the treatment housing 121 by centrifugal force.

The treatment discharge unit 125 may be positioned in a tangential direction on the outer circumferential surface of the treatment housing 121 corresponding to the upper side of the treatment plate 121 ′ and may be connected to the treatment space 102a. After the dry waste is moved toward the inner circumferential surface of the treatment housing 121 by the centrifugal force according to the rotation of the treatment plate 121 ′, the dry waste flows into the treatment discharge unit 125 to pass the treatment discharge unit 125. It can be discharged to the lower side through.

In addition, the treatment discharge unit 125 may be formed in a plurality, and may be positioned in the vertical direction. Each of the treatment discharge units 125 may be located on the outer circumferential surface of the treatment housing 121 while being located above a different treatment plate 121 ′. In addition, the processing plates 121 ′ may have relatively small processing openings 121a as they are positioned at the lower side. For this reason, the dry waste may have a relatively small size as it is discharged through the treatment discharge unit 125 located at a relatively lower side.

Meanwhile, a storage container 200 may be located under the treatment discharge unit 125. The dry waste may be introduced into the storage container 200 and stored after being discharged from the treatment discharge unit 125. Dry waste stored in each storage container 200 may have a uniform size.

The molding unit 103 is positioned to be spaced apart from the processing unit 102, and may be supplied in a mixed state of dry waste and sawdust to generate pellets. Here, it may be preferable that the dry waste is classified by size in the treatment unit 102, and the sawdust is stored in the storage container 200 separately from the dry waste and has a size similar to the size of the dry waste.

In particular, it may be desirable to mix the dry waste and sawdust in a ratio of 5:5 to 7:3. For example, 5 kg of dry waste and 5 kg of sawdust may be mixed, or 7 kg of dry waste and 3 kg of sawdust may be mixed. When the ratio of dry waste and sawdust is less than 5:5, that is, when the dry waste is less than sawdust, the odor caused by the dry waste may be reduced due to the sawdust, but the sawdust may be excessively introduced, resulting in an increase in cost. In addition, when the ratio of the dry waste and sawdust is less than 7:3, that is, when the dry waste is more than the set value and more than the sawdust, odor due to the dry waste may be generated.

Pellets produced from dry waste and sawdust mixed in the same ratio as described above may exhibit a high calorific value obtained by combining dry waste and sawdust while reducing odor due to dry waste based on food waste due to sawdust.

In addition, the molding part 103 may include a molding body 131, a molding drive part 133, a supply guide part 135, and a molding discharge part 137.

The supply induction part 135 may be located on the upper surface of the molding body 131. Dry waste and sawdust may be supplied to the supply guide unit 135 in a mixed state and supplied to the molding body 131. Here, the supply guide portion 135 is formed with a supply space (135a) having a hollow shape, the supply space (135a) may be connected to the inside of the molding body 131 while having a cross-sectional area that gradually decreases toward the lower side. Dry waste and sawdust can be easily supplied to the molding body 131 through the upper surface of the supply space 135a having a relatively large cross-sectional area in a mixed state.

The molding discharge part 137 is connected to the side surface of the molding body 131 and may be positioned so as to be inclined downward from the side surface of the molding body 131. The pellets may be discharged from the molding body 131 to the molding discharge part 137 after being produced in the molding body 131, and may be moved downward along the molding discharge part 137.

The transfer unit 104 may transfer the dry waste from the drying unit 101 to the processing unit 102 and supply the dry waste to the processing unit 102. Here, the transfer unit 104 may connect the discharge port 101b of the drying unit 101 and the upper surface of the processing unit 102.

In addition, the transfer unit 104 may include a collection body 141, a first transfer guide 143, a second transfer guide 145 and a transfer body 147.

The collection body 141 may be connected to the drying unit 101 to correspond to the outlet 101b of the drying unit 101. Dry waste may be discharged from the discharge port 101b and introduced into the collection body 141.

The first transfer guide 143 is formed in a circular tubular shape, and may be connected to the collection body 141. Here, the first transfer guide 143 may extend from the collection body 141 and be positioned above the processing unit 102.

The second transfer guide 145 is formed in a circular tubular shape, and may be positioned in a vertical direction at the center of the upper surface of the processing unit 102, in particular, the processing housing 121 and connected to the first transfer guide 143.

The transfer body 147 has a screw shape, and may be positioned along the first transfer guide 143 within the first transfer guide 143. Here, the transfer body 147 may be rotated about an axis along the first transfer guide 143. In addition, the dry waste introduced into the collection body 141 may be transferred to the second transfer guide 145 along the first transfer guide 143 by rotation of the transfer body 147. The dry waste may fall along the second transfer guide 145 after reaching the second transfer guide 145 and be supplied to the treatment space 102a of the treatment unit 102.

The transfer unit 104 as described above can easily supply dry waste to the treatment unit 102.

The fuel manufacturing apparatus 100 using food waste according to the present embodiment generates dry waste by drying the food waste in the drying unit 101, and separating the dry waste by size in the treatment unit 102 to separate the sawdust and 5:5 to 7 By mixing in a ratio of :3, pellets can be produced in the molding part 103. Here, the pellets are in a state in which dry waste and sawdust are mixed according to drying of food waste, and thus may have a relatively high amount of heat. Accordingly, the fuel manufacturing apparatus 100 using food waste according to the present embodiment may generate and recycle the food waste into pellets usable as fuel. In addition, environmental pollution problems may be solved to some extent through recycling of food waste.

In addition, the fuel manufacturing apparatus 100 using food waste of this embodiment dries the food waste when it treats the food waste so that it can be used as fuel and does not have any additional additives other than relatively inexpensive sawdust. The resulting cost can be minimized.

These are drawings showing the operation of the modified storage container 200 used in the fuel manufacturing apparatus 100 using food waste.

4 and 5, the storage container 200 used in the fuel manufacturing apparatus 100 according to an embodiment of the present invention may be modified. The storage container 200 of the present embodiment may be used to store and mix dry waste and sawdust, which may each be in a powder form, and to mix with each other. Here, it may be desirable that the storage container 200 is located spaced apart from the ground.

In addition, the storage container 200 may include a container body 201, a partition 202, a cover 203 and an auxiliary cover 204.

The container body 201 is formed in a cylindrical shape, but may receive and store dry waste or sawdust. A storage space 211, a guide opening 213, and a discharge opening 215 may be formed in the container body 201.

The storage space 211 may be concavely formed on the upper surface of the container body 201, and may be formed in a cylindrical shape such as the container body 201.

The guide opening 213 is made of a plurality, each partially formed along the circumferential direction of the container body 201 on the outer circumferential surface of the container body 201, and may connect the inside and the outside of the storage space 211. In addition, the guide openings 213 may be formed to be parallel while being spaced apart from each other along the vertical direction, that is, the height direction of the container body 201.

The discharge opening 215 is partially formed on the lower surface of the container body 201 and may connect the inside and the outside of the storage space 211. Here, the discharge opening 215 may be formed in a fan shape based on the center of the lower surface of the container body 201.

The partition 202 is formed in a plate shape, and may be hingedly connected to the container body 201 so as to correspond to the guide opening 213. Here, the partition 202 may be located outside the storage space 211, rotated to be inserted into the guide opening 213, and positioned inside the storage space 211. When the partition 202 is located inside the storage space 211, the partition 202 may contact the inner peripheral surface of the storage space 211 in which the guide opening 213 is not formed along the circumferential direction, and the storage space 211 may be partitioned along the height direction of the container body 201 by the partition 202.

When the guide openings 213 are formed at regular intervals, the partition 202 is located inside the storage space 211, so that the storage space 211 can be divided into the same volume.

On the other hand, the partition 202 of the present embodiment is shown to be made of two to correspond to the number of the guide openings 213, but is not limited thereto, and may be formed of three or more while corresponding to the number of guide openings 213.

The cover 203 may be positioned to correspond to the discharge opening 215 on the lower surface of the container body 201. Here, the cover 203 may open and close the discharge opening 215.

With the cover 203 closed the discharge opening 215, dry waste or sawdust may be supplied to and stored in the storage space 211. Meanwhile, when the cover 203 opens the discharge opening 215, dry waste or sawdust stored in the storage space 211 may be discharged from the storage space 211 through the discharge opening 215.

The auxiliary cover 204 is formed in a flexible sheet shape, but is located on a part of the inner circumferential surface of the storage space 211 and is unfolded to close the guide opening 213 at the same time. Here, the upper end of the auxiliary cover 204 may be fixed to the inner circumferential surface of the storage space 211.

In particular, when the partition 202 is located outside the storage space 211, it is unfolded on the inner circumferential surface of the storage space 211 to close the guide opening 213 at the same time, dry waste or sawdust is stored in the storage space 211 When supplied to and stored, dry waste or sawdust may not be discharged through the guide opening 213 by the auxiliary cover 204.

When the partition 202 is rotated to be located inside the storage space 211 through the guide opening 213 while the partition 202 is located outside the storage space 211, the auxiliary cover 204 is deformed to be bent and the partition 202 ) Can be located on the top surface. Dry waste or sawdust stored in the storage space 211 may be subdivided by the partition 202. Here, the subdivided amount may be subdivided by an amount considering the mixing ratio of dry waste and sawdust.

For example, in a state in which 30 kg of dry waste is supplied to the storage space 211 of one storage container 200, the partition 202 may subdivide the dry waste of the storage space 211 by 10 kg. . In addition, in a state in which sawdust of 15 kg to 30 kg is supplied to the storage space 211 of the other storage container 200, the partition 202 subdivides the sawdust of the storage space 211 by 5 kg to 10 kg can do. For this reason, the storage container 200 can easily mix dry waste and sawdust in a predetermined ratio (for example, 5:5 to 7:3) by subdivided amounts.

The storage container 200 as described above may be used to mix dry waste and sawdust as follows. Here, it may be desirable that the storage container 200 has a different size for dry waste and sawdust.

In the storage container 200, the partition 202 is located outside the storage space 211 of the container body 201, the cover 203 closes the discharge opening 215, and the auxiliary cover 204 is unfolded to guide The opening 213 is closed. Here, dry waste or sawdust may be supplied to and stored in the storage space 211 (see FIG. 5(a)).

In a state in which dry waste or sawdust is stored in the storage space 211, the partitions 202 may be rotated and positioned inside the storage space 211 through the guide opening 213. Here, it may be preferable that the partition 202 located at the lower side is preferentially rotated to be located inside the storage space 211. In addition, the auxiliary cover 204 may be moved upward by the partition 202 from the lower side. Dry waste or sawdust may be subdivided by the partition 202 in a state stored in the storage space 211 (see FIG. 5(b)).

When the cover 203 opens the discharge opening 215, the dry waste or sawdust is discharged from the storage space 211 through the discharge opening 215, so that the dry waste and the sawdust may be positioned to be mixed. Here, dry waste or sawdust stored in the storage space 211 between the partition 202 and the discharge opening 215 located inside the storage space 211 may be discharged through the discharge opening 215. That is, the amount of dry waste or sawdust subdivided in the storage space 211 partitioned by the partition 202 may be mixed and prepared to be supplied to the molding unit 103.

The storage container 200 as described above may be prepared to receive and store dry waste or sawdust, subdivided by using the partition 202, and mixed by the subdivided amount to be supplied to the molding unit 103. In addition, dry waste and sawdust may be subdivided into small amounts in a state stored in the storage container 200, discharged from the storage container 200 in a subdivided amount, and mixed to be used to produce a small amount of pellets.

Above, the technical idea of the present invention has been described in detail with reference to preferred embodiments, but the technical idea of the present invention is not limited to the above embodiments, and those skilled in the art within the scope of the technical idea of the present invention Various modifications and changes are possible by the user.
