Reference numerals "21" and "23" in the drawings denote heat insulating materials.

Referring to Figures 1 to 9 the operational relationship of the present invention configured as described above are as follows.

First, when the crusher 2 is rotated in the state in which food waste is put into the hopper 1, the food waste is finely crushed by the rotation of the crusher, and the trash is put into the dehydration apparatus 3. In this case, since the dehydration apparatus 3 is rotating at a high speed, a large amount of water (dehydration liquid) contained in finely crushed food waste is centrifuged to form a plurality of drainages formed on the entire outer circumference of the dehydration apparatus 3. It exits through the hole 7 to the outside.

At this time, the outer cylinder 12 is formed on the outer periphery of the dewatering device 3 so as to surround the dehydrating device 3 so that the dehydrating liquid discharged to the outside from the entire outer circumference of the dewatering device 3 is located inside the outer cylinder 12. While hitting down, it is supported by the tray 25 through the dehydration outlet 11.

When the dehydration liquid is applied to the tray 25, the water level detector 24 installed in the tray 25 detects that dehydration liquid has flowed into the tray 25, and operates a heater 22 such as a burner or a heater to heat the heater ( The dehydrating liquid received on the tray 25 is heated to boil by the heat source generated in 22).

At this time, the tray 25 is formed in a shallow depth and a wide shape to evaporate while bouncing in a short time, so that the dehydration liquid in the tray 25 is drowsy so that the water level sensor 24 is lost in the tray 25 Detecting the dehydration is exhausted to stop the operation of the heater 22 to prevent the tray 25 from overheating.

In addition, the tray 25 includes a temperature sensor 17 for sensing a temperature of the heater 22 and the tray 25, and an overheat detector 18 for detecting that the tray 25 and the heater 22 are overheated. It can be installed to prevent the occurrence of fire.

As the dehydration liquid is heat-treated in the tray 25 as described above, the debris from which the dehydration liquid is centrifuged in the dehydration apparatus 3 is introduced into the heating apparatus 20 from the dehydration apparatus 3 and is incinerated. Let's take a look at the process.

As the dehydration device 3 rotates at a high speed as described above, the debris from which the water is centrifugally dehydrated while the water is drained out is discharged through the outlet 6 by a spiral screw blade 8 installed at the inner circumference of the dewatering device 3. The incineration chamber 15 is introduced into the incineration chamber 15 of the heating device 20, and the residue introduced into the incineration chamber 15 is incinerated by a heat source of a heater 16 such as a heater or a burner that operates for a time set by a timer. Lose.

The residue introduced into the incineration chamber 15 is placed on at least one stage of the support mesh 19 installed at the inside of the incineration chamber 15, and in this state, high heat is applied to the residue placed on the support mesh 19 to incinerate. This is done. The residue introduced into the incineration chamber 15 is finely crushed by the crusher and the water is dehydrated in the dehydrator 3 so that incineration is performed in a short time, and the support wire mesh 19 uses the large scale to remove the residue. As it is incinerated, the debris (ash) falls down and is supported by the ash tray 14.

As described above, the exhaust fan 26 installed on the deodorizer 28 side operates in the process of incineration of the debris, and through the exhaust pipe 28a provided between the deodorizer 28 and the lower part of the incineration chamber 15. Smoke exits to the deodorizer 28, and the odor generated in the process of heating and evaporating the dehydration liquid received on the tray 25 also flows into the deodorizer 28 by the suction force of the exhaust fan 26, thereby deodorizing the machine. Only the air purified and purified at 28 is exhausted to the outside.

As described above, incineration of the residue while the heater 16 generates heat in the incineration chamber 15 is turned on and off for a set time of a timer controlled by a control device (not shown), and the heating device of the incineration chamber 15 ( 20 also detects the temperature of the incineration chamber 15 by the temperature sensor 17 and the overheat sensor 18 in the same way as the tray 25 to detect the overheating to prevent the fire in advance.

Next, a description will be given of this embodiment of the present invention shown in FIG.

The food waste introduced into the hopper 1 is finely crushed by a crusher and introduced into the dehydrating apparatus 3, and the food waste introduced into the dehydrating apparatus 3 is edible by the centrifugal force of the dehydrating apparatus 3 rotating at high speed. Moisture contained in the trash flows out of the dehydrating device (3) and flows down to the tray (25) installed in multiple stages through the dehydrating liquid outlet (11) of the outer cylinder (12). Through) is discharged to the chute (13) side.

Since the food waste is finely crushed in the crusher, it turns out that the dehydration effect is great.

As described above, when the dehydration liquid flowing through the dehydration liquid outlet 11 is larger than the amount supported by the tray 25, the dehydration liquid flows down to the tray 25 positioned below it and is supported. When all are supported, it flows down to the storage tank 30 installed at the bottom end and is supported.

When the dehydration liquid is applied to the tray 25 and the storage tank 30 installed in this way, the water level sensor 24 installed in each tray 25 detects that the dehydration liquid is applied to the tray 25. A heater 22 such as a heater or burner is operated to heat each tray 25 so that the dehydrating liquid inside the tray 25 is simmered.

As described above, when the dehydration liquid in the tray 25 is simmered and removed, the water level sensor 24 detects this and stops the operation of the heater 22. When the dehydration liquid remains in the water storage tank 30, the water storage tank The water level detector 29 installed in the 30 detects this and heats the dehydrating liquid contained in the water storage tank 30 to the uppermost tray 25 through the bypass pipe 31.

Debris from which the dehydrating liquid is dehydrated inside the dewatering device 3 is discharged to the chute 13 along the screw blades 8 spirally installed on the inner circumference of the dewatering device 3 as in one embodiment. On the outlet 6 side of the dewatering device 3, as shown in FIGS. 2 and 4, the secondary crusher 32 is installed to rotate in the opposite direction to the dewatering device 3, and the chute 13 is formed to be wider toward the lower side. The debris leaving the outlet 6 of the dewatering device 3 is crushed by the secondary crusher 32 to be secondarily displaced and placed on the top conveyor 33 in a widely spread state.

The dregs spread and spread on the uppermost conveyor 33 as described above are moved by the rotational movement of the conveyor 33. The heater 34 such as a burner or a heater is disposed at a predetermined position of the conveyor 33. Residue carried on the conveyor 33 by the heat generated from the combustion starts to burn. At this time, the residue placed on the conveyor 33 is crushed finely in the shredder 2, as described above, the water is dehydrated in the dehydrator 3 and is shredded while being shredded in the secondary shredder 32, the conveyor 33 Because it is placed on a thin layer, these residues are easily burned.

In addition, in FIG. 5, the residue placed on the uppermost level shows that the residue is moved to a thin thickness by narrowing the gap between the opening of the chute 13 and the upper surface of the conveyor 33.

The conveyor 33 is installed in a multi-stage zigzag form as shown in Figure 2 so that the residue that was burned in the upper conveyor (33) is carried on the conveyor 33 of the lower side and is burned secondly, 2 The residue that was burned by the car falls back to the conveyor 33 at the lower end and is burned at the conveyor 33 at the lower end thereof.

The dehydrated wastes are completely incinerated while passing through the multi-stage conveyor 33, and the incineration of the dregs is completed by falling to the ash tray 35 installed below the lowermost conveyor 33.

As described above, the smoke and odor generated during incineration of the debris are purged by the deodorizer 28 while being exhausted to the deodorizer 28 through the exhaust pipe 28a installed under the heater case 33a. The air is exhausted to the outside, and the operation of the heater 34 installed in each of the conveyors 33 is controlled by the set signal of the timer.

Next, a description of the third embodiment of the heating device shown in Figure 6, when the dehydration device (3) is dehydrated when the residue flows into the inside of the heating tube 39 through the chute 13 screw conveyor (40) ) Rotates forward and backward at regular time intervals, and once again moves the residue backwards so as not to be discharged through the rear discharge port 38, and once again moves to the front side. Since the heater 36 is mounted on the outer circumference and generates heat, the waste is incinerated by the high heat generated by the heater 36. The waste incinerated for a predetermined time is received by the ash tray 35 through the discharge port 38. You lose.

In this type of incineration type food waste treatment apparatus installed with the heating apparatus of the third embodiment, the dehydration apparatus 3 is operated for a predetermined time to supply a predetermined amount of debris to the heating tube 39, and a predetermined amount of the waste to the heating tube 39. When the dregs are introduced, when the screw conveyor 40 is rotated forward and backward, the operation of the dehydrator 3 stops, indicating that the dregs should no longer be supplied to the heating tube 39.

The operation of the actual example of the heating apparatus shown in FIG. 7 shows that when the dehydration debris from the dehydration apparatus 3 flows into the inside of the heating tube 42, the rotating shaft 44 rotates in the forward and reverse directions while the rotating shaft ( Agitating wings 43 radially installed on 44) stir the residue introduced into the heating tube 42. At this time, since the heater 36 is mounted on the outer circumferential edge of the heating tube 42 to generate heat, the waste is incinerated by the high heat generated by the heater 36, and when incineration is performed for a time set by the timer. Rotation of the rotating shaft 44 is stopped.

When the rotation of the rotary shaft 44 is stopped as described above, incinerated debris accumulates to the inner lower part of the heating tube 42, and then the pinion 46 rotates to rotate the rack 45 to go straight. At the distal end portion of the 45, a pusher 47 for pushing the incinerated debris toward the opening / closing opening 41 is installed, while the incinerated debris is pushed out to the straight pusher 47 while opening and closing the opening 41 in a hinged manner. It falls to the outer bottom of the heating tube 42 and is supported by the ash tray 35.

It is noted that the movement of the pusher 47 moves between a predetermined distance c formed between the free end of the stirring blade 43 and the inner circumference of the heating tube 42.

The following describes the operation of another embodiment of the shredder shown in FIG.

Rotating a pair of shredders (2) (2a) in the opposite direction to each other while the food waste is introduced into the hopper (1), each food shredder (2) while the food waste passes between the pair of shredders (2) (2a) Crushing is performed by crushing blades protruding on the outer circumference of the circumference (2a). When two foreign crushers (2) (2a) are stuck with foreign matter, the crusher 2 on one side has its shaft fixed in its position. The crusher 2a on the other side is installed so that the shaft 2b is variable in position in a state in which the spring 49 is installed in the long groove 48 formed with the shaft 2b inclined downwardly in the hopper 1, so that each crusher ( 2) (2a) rotates in the opposite direction to each other, each biting the foreign object between the two crushers (2) (2a) hard to break.

At this time, one of the crusher 2 is to rotate in place and the other crusher (2a) is to be lowered along the downwardly inclined long groove 48, two crushers (2) than the elasticity of the spring (49) Since the driving force of the motor driving the 2a is stronger, the crusher 2 on one side rotates in place and the crusher 2a on the other side is pushed by the hard foreign matter caught by the two crushers 2, 2a. Between the two shredders (2) (2a) is to pass a hard foreign matter.

Even when the two crushers 2 and 2a are opened as described above, the two crushers 2 and 2a are rotated in opposite directions to each other. As shown in FIG. When the press roller 51 for elasticity of the chain 50 is elastically installed on the outer side of the chain 50 which rotates 2) in the reverse direction, the gap between the two shredders 2 and 2a is opened. Edo chain 50 is to be rotated without receiving the driving force of the motor as it is not relaxed.

Finally, the operation of another embodiment of the dehydration device 3 shown in FIG.

The dewatering device 3 according to another embodiment is a compression type dewatering device 3, wherein when the food waste flows from the hopper 1 into the taper body 52, the taper screw rotates at a low speed by the rotational force of the motor. The food waste is compressed between the inner surface of the taper body 52 and 55, and the water contained in the food waste is dehydrated and discharged into the dehydration hole 53. In this embodiment, the tapered body 52 and the inside thereof are dehydrated. Inserted and rotated taper screw 55 is formed in a tapered shape, the space between the inner surface of the tapered body 52 and the tapered screw 55 becomes narrower toward the rear, so the food waste is compressed in the narrowing space of the food waste It will dehydrate the water contained in.

In the description of the present invention, it has been described that incineration of dehydrated debris, but it can also be dried by adjusting the time to incinerate the debris, this dried residue is found to be used as feed for livestock .

As described above, the food waste of the present invention is processed by heating the vegetable waste from the agricultural product market, food waste from a general home or a restaurant by heating with a heat source such as an electric heater or a burner flame, and treating the food waste efficiently.
