Is arranged.

As shown in Figure 2 and 3, the rotary garbage drying apparatus 100 according to the present invention, the drying furnace 130 is arranged to be rotatable inside the main body portion 110, such drying Furnace 130 is formed through the upper inlet 140 to form a receiving space in which a predetermined waste is contained therein, is installed on both sides of the lower structure is provided with electric heaters (142a, 142b) for heating and drying the waste. .

Such a rotary drying furnace 130 is connected to the first body 132 of the semi-cylindrical structure and the second body of the semi-cylindrical structure that is integrally fixed to the bolt 136 in the circumferential direction to the first body 132 ( 134, and an exhaust port 138 is formed in the upper portion of the first body 132 to exhaust the waste heated by the heaters 142a and 142b, and in the upper portion of the second body 134. The inlet 140 having a larger size than the exhaust port 138 is formed.

In addition, as illustrated in FIGS. 4A and 4B, the exhaust port 138 and the inlet 140 form jaw portions 138a and 140a protruding from the first and second bodies 132 and 134, respectively, on the edge thereof. The structure is distinguished from the first and second bodies 132 and 134.

In addition, the rotary drying furnace 130 has a structure for crushing and stirring waste more effectively by interacting with the screw 160 rotating inside the first and second bodies 132 and 134. 130, the plurality of first bar protrusions 144 having a straight bar shape are formed on the inner circumferential surfaces of the first and second bodies 132 and 134 so as to protrude upward to a height close to the screw 160 at a predetermined circumferential distance. A plurality of second and third locking protrusions 146 and 148 are formed in a plurality of stages, and the front and rear inner surfaces of the first and second bodies 132 and 134 respectively extend in a plurality of radial bars. Structure.

Therefore, when the screw 160 rotates in the rotary drying furnace 130, the first, second and third locking protrusions 144, 146, and 148 have a large resistance to rubbish in the first and second bodies 132 and 134. This results in more efficient shredding and agitation of the waste.

In addition, the rotary garbage drying apparatus 100 according to the present invention includes a screw 160 that rotates inside the drying furnace 130 to agitate and crush the garbage contained in the drying furnace 130.

As shown in FIG. 3, the screw 160 may be detached horizontally from the drive shaft 174 of the motor 172 through the shaft coupling 162 at one end of the screw shaft 161a at the center thereof. Is connected, and is supported on one side of the main body 110.

In addition, the other end of the screw shaft 161a is rotatably supported through the shaft support bushing 164 at the other side of the main body 110 so that the screw shaft ( 161a freely rotates forward and reverse with respect to the main body 110.

At the same time, such a screw shaft 161a is rotatably connected to the drying furnace 130. For this purpose, the center of the front and rear surfaces of the drying furnace 130 are penetrated through the first and second bushings 166a and 166b, respectively. It is connected.

Therefore, the forward and reverse rotation operation of the motor 172 allows the screw shaft 161a to freely forward and reverse rotation with respect to the main body 110 and the drying furnace 130.

In addition, such a screw 160 is shown in Figure 5a to 5c, a plurality of spiral grinding blades (161b) along the screw axis 161a in the center of the screw shaft 161a in the circumferentially equal intervals Equipped.

Each of the grinding blades (161b) is for stirring and crushing the waste during the rotation operation, is formed in three different positions around the screw shaft (161a) in three different positions, each of the grinding blades (161b) As shown in FIG. 5C, the width forms a circumferential angle θ of 120 degrees or less.

Accordingly, such a screw 160 has a horizontal side portion of the screw shaft 161a in which any one of the grinding blades 161b is formed to form an empty space 161c, respectively, as described later, and the drying furnace 130 ) So as not to disturb the input or discharge of garbage into the house.

In addition, the rotary garbage drying apparatus 100 according to the present invention is connected to the screw shaft 161a from the outside of the main body 110, the drive unit having a motor 172 for rotating the screw 160 forward, reverse ( 170).

The motor 172 of the driving unit 170 is horizontally separated through the shaft coupling 162 at one end of the screw shaft 161a, as the driving shaft 174 is shown in FIGS. 1 and 3. As is possible connected, the screw shaft 161a is to be rotated forward and reverse.

The rotary garbage drying apparatus 100 according to the present invention transmits the rotational force of the screw shaft 161a which is rotated forward and reverse by the motor 172 of the driving unit 170 to the drying furnace 130 as described above. The drying furnace 130 is provided with a power connection unit 180 that integrally rotates forward and reverse together with the screw shaft 161a.

As shown in FIGS. 6, 7A, and 7B, the power connection unit 180 includes a moving unit 182 that is screwed to the thread P of the screw shaft 161a, and the moving unit ( 182 is rotated between the inner surface of the body portion 110 and the outer surface of the drying furnace 130 is constrained to move forward and backward along the screw shaft (161a) during the forward and reverse rotation operation of the screw 160. .

However, such a moving unit 182 transmits the rotational force of the screw shaft 161a to the drying furnace 130 in a state of being in close contact with the drying furnace 130, thereby transferring the drying furnace 130 to the screw shaft 161a. It is a structure that rotates forward and reverse together.

To this end, the moving unit 182 of the power connection unit 180 has a thread P at a position between the shaft coupling 162 of the screw shaft 161a and the first bushing 166a, as shown in FIG. 7A. And a spiral portion 184a screwed to the blade) and a plurality of wing portions 184b extending horizontally in parallel to both sides of the spiral portion 184a.

In addition, the plurality of wing portions 184b are respectively supported by the first support jaw 186 protruding horizontally from the inside of the front surface of the main body portion 110 toward the drying furnace 130, and the plurality of wings. The portion 184b is supported by a second support jaw 188 whose upper surface protrudes horizontally from the front outer side of the drying furnace 130 to the main body portion 110 side from the top of the first support jaw 186. In the forward and reverse rotation operation of the screw shaft 161a, the blade 184b is constrained to rotate by the first and second support jaws 186 and 188, respectively.

Accordingly, in the moving unit 182, the spiral portion 184a is linearly moved forward and backward along the thread P of the screw shaft 161a.

In addition, when the moving unit 182 moves toward the drying furnace 130, the power connection unit 180 may have a pressing force acting therebetween to move the moving unit 182 to the second supporting jaw of the drying furnace 130. 188), the spiral portion 184a of the moving unit 182 forms a polygonal outer circumferential surface 190a, as shown in Figure 7a, and the drying furnace As shown in FIG. 7B, the second support jaw 188 protruding from the outside of the front surface of the 130 is formed with a polygonal support surface 190b that coincides with the polygonal outer circumferential surface 190a of the spiral portion 184a. do.

Therefore, when the moving unit 182 advances toward the drying furnace 130, a pressing force acts on the drying furnace while the polygonal outer circumferential surface 190a of the spiral portion 184a is coupled to the polygonal support surface 190b of the second support jaw 188. Thus, the moving unit 182 is locked in a state in which it is engaged with the second supporting jaw 188 of the drying furnace 130.

In this state, when the screw shaft 161a is rotated, the moving unit 182 rotates simultaneously with the drying furnace 130 in conjunction with the rotation operation of the screw shaft 161a.

And the rotary garbage drying apparatus 100 according to the present invention when the moving unit 182 and the drying furnace 130 is rotated with the rotation of the screw shaft 161a, the rotation is limited to 180 degrees the drying The inlet 140 of the furnace 130 is arranged in a state located at the bottom from the state located at the top.

In this case, as shown in FIG. 8, the main body 110 has a first stopper 210 of a predetermined height protruding from one side of an inner side thereof, and an inner side of the main body 110 than the first stopper 210. The second stopper 212 protrudes from a low position, and the drying furnace 130 located inside the main body 110 forms a locking jaw 214 protruding from one side of the outer side of the first stopper. And to selectively contact 210 or the second stopper 212.

As shown in FIG. 9A, when the locking step 214 is in contact with and supported by the first stopper 210 of the main body 110, the inlet 140 of the drying furnace 130 is positioned at an upper portion thereof. The waste is introduced into the inside, and stirring and crushing are performed.

However, when the drying furnace 130 is rotated such that the inlet 140 faces the lower side discharge hopper 112 of the main body 110, as shown in FIG. 9B, the locking jaw 214 is formed in a first manner. The second stopper 212 limits the rotation of the drying furnace 130 by 180 degrees by being rotated and supported from the stopper 210 to the second stopper 212, and the inlet 140 of the drying furnace 130 is discharged. It acts as to discharge the waste processed in the interior of the drying furnace 130 to the outside through the discharge hopper (112).

The rotary garbage drying apparatus 100 according to the present invention configured as described above is an input port 140 of the upper side of the drying furnace 130, for example, when food waste is input, such waste is pulverized by the screw 160. It is easily introduced into the drying furnace 130 through the empty space 161c formed between the wings 161b.

Conventional screws (not shown) are formed without the same empty space around the axis, so that the grinding blades grind the food while the forward and reverse rotation, this general screw is finished, the grinding blade of the screw is located directly under the inlet In this case, there was a problem that food waste is not put well due to the crushed wing.

However, in the screw 160 of the present invention, each of the grinding blades 161b is formed at different positions in three directions about the screw shaft 161a, and the grinding blades 161b each have a width of 120 degrees or less. Since the circumferential angle θ is formed and the horizontal side portions of the screw shaft 161a each have a hollow space 161c, they do not interfere with the input and discharge of waste into the drying furnace 130 at all. Easy to do (see Figs. 9A and 9B).

Then, in the state in which the waste is put, the motor 172 rotates forward and reverse. Accordingly, the screw 160 rotates forward and backward together through the screw shaft 161a, and the waste contained in the drying furnace 130. The stirring and crushing is made while moving back and forth, and at the same time, the heaters 142a and 142b operate to perform heating.

In this process, as the grinding blades 161b of the screw 160 rotate, the first, second and third locking protrusions 144, 146, and 148 formed on the first and second bodies 132 and 134 of the drying furnace 130. The wastes are then subjected to great resistance to the waste, which in turn causes the waste to be broken and stirred more effectively.

On the other hand, during the forward and reverse rotation operation of the screw 160, the moving unit 182 of the power connection unit 180 is moved forward and backward in the thread (P) portion of the screw shaft (161a).

That is, a screw thread (P) is formed at a portion immediately next to the portion where the screw shaft (161a) is coupled to the motor (172), and the central spiral portion (184a) of the moving unit (182) is screwed to the screw thread (P). It is.

Therefore, when the screw 160 rotates, the moving unit 182 fastened to the thread P also moves along the thread P. At this time, both wing portions 184b of the moving unit 182 are the main body portion ( The lower surface is supported by the first supporting jaw 186 protruding horizontally from the inner side of the front surface toward the drying furnace 130, and the upper surface of the plurality of wing portions 184b is the drying furnace 130. It is supported by the second support jaw 188 protruding horizontally from the front outer side of the upper portion of the first support jaw 186 toward the main body 110, the wing portion during the forward and reverse rotation operation of the screw shaft (161a) 184b is freely constrained by the first and second support jaws 186 and 188, respectively.

Accordingly, the moving unit 182 moves forward along the thread P of the screw 160 when the motor 172 rotates left, and moves along the thread P when the motor 172 rotates right. It moves back and moves straight forward and backward along the thread P of the screw shaft 161a.

As the motor 172 rotates left and right through this operation, the grinding blades 161b of the screw 160 repeat the stirring (mixing) and crushing the food waste, and such stirring and crushing drying are performed. When the ground, the motor 172 starts to rotate continuously in one direction (for example, left turn).

Then, the moving unit 182 moves forward along the thread P, and is closely attached to the second supporting jaw 188 of the drying furnace 130 to be strongly coupled to the drying furnace 130.

In this case, as shown in FIG. 7A, the spiral part 184a of the moving unit 182 forms a polygonal outer circumferential surface 190a and protrudes from the front outer side of the drying furnace 130. As shown in Figure 7b, by forming a polygonal support surface (190b) to match the polygonal outer peripheral surface (190a) of the spiral portion (184a) is securely coupled and the pressing action to the outer wall end surface by drying the The moving unit 182 is locked while being engaged with the second supporting jaw 188 of the drying furnace 130, and the plurality of wings formed in the moving unit does not move beyond the first supporting jaw of the main body 110 before being transferred to the drying furnace. Rotation is free

When the moving unit 182 is engaged with the drying furnace 130 as described above, the screw shaft 161a is rotated by the continuous rotation of the motor 172, and the moving unit 182 coupled to the drying furnace 130 is The drying furnace 130 is rotated.

Such a rotating state of the drying furnace 130 is shown in Figs. 9a and 9b.

That is, when the drying furnace 130 is rotated, the locking jaw 214 is rotated and supported from the first stopper 210 to the second stopper 212, thereby limiting the rotation of the drying furnace 130 by 180 degrees, and the motor. The rotation of 172 is stopped.

In the rotated state, since the waste inlet 140 faces downward from the top, the inlet 140 acts as an outlet so that the waste in the dried state exits from the interior of the drying furnace 130.

At this time, the waste in the drying furnace 130 is the lower discharge hopper of the main body 110 through the inlet 140 acting as an outlet due to the empty space (161c) between the grinding blades (161b) formed in the screw 160 ( 112) The waste is smoothly discharged to the side.

After the waste is discharged as described above, the drying furnace 130 again rotates in reverse. In this case, the motor 172 reversely rotates (for example, rotates right), and reversely rotates the screw shaft 161a. At the same time, the moving unit 182 and the drying furnace 130 are reversed from the discharge position shown in Figure 9b to the input position shown in Figure 9a.

At this time, since the drying furnace 130 and the moving unit 182 are engaged with each other, the moving unit 182 and the drying furnace 130 are reversely rotated at the same time as the screw shaft 161a is reversely rotated. The locking jaw 214 of the 130 is supported by rotating from the second stopper 212 to the first stopper 210 to limit the reverse rotation of the drying furnace 130 to 180 degrees, and to input the drying furnace 130. Return to the state.

As such, when the locking step 214 of the drying furnace 130 is supported by the first stopper 210 and the reverse rotation of the drying furnace 130 is blocked, the reverse rotation of the screw shaft 161a is the drying furnace 130. A polygonal outer circumferential surface 190a of the spiral portion 184a of the moving unit 182 is forced out of the polygonal support surface 190b formed at the second support jaw 188 of FIG.

Therefore, the moving unit 182 retreats along the thread P of the screw shaft 161a from the second supporting jaw 188 of the drying furnace 130, and the first supporting jaw 186 of the main body 110. When coupled to the main body 110, the driving of the motor 172 is stopped.

In such a state, new waste is newly introduced into the inlet 140 side of the drying furnace 130, and when the input is completed, the motor 172 is started again and repeats the forward and reverse rotations. Stirring, crushing and drying operation is to be made repeatedly in the interior of the drying furnace (130).
