DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing machine for making garbage into fine powder and incinerating it.

[0002]

2. Description of the Related Art In recent years, disposal of garbage discharged from fresh markets such as fish and vegetables, food factories, catering centers and restaurants has become a problem. Most of the garbage discharged from this area is incinerated or landfilled at municipal incineration facilities.However, due to problems such as air pollution, disposal costs, and disposal sites, disposal methods such as composting are being implemented. It has become.

[0003] In this method of composting, certain types of garbage are easily composted, but some garbage discharged from a kitchen cannot be composted because various things such as bones are mixed therein. In addition, various kinds of bacteria are added to composting, and if the temperature and humidity are not controlled, they may rot and not be composted. Even if composting is used, there is no place to use the manufactured compost because there is little agricultural land in urban areas, and there is a problem that it becomes new waste.

Therefore, instead of composting, a type has been developed in which garbage is decomposed into carbon dioxide and water by using bacteria to be eliminated. However, these bacteria also rot if not properly controlled in temperature and humidity, and there are many practical problems. In addition, a household processing machine has been developed in which garbage is heated and dried by an electric heater without using bacteria to reduce the weight. However, such a processor for reducing the amount of heating requires a high electricity cost, and there is a problem that the reduced amount of garbage must be further disposed of.

The rotating drum 25 supported by the disc-shaped rings 33, 33 rotates on the “b”.

On the other hand, the burner 6 is ignited and its combustion flame 4
The combustion chamber 1 is heated by 3 and the burned exhaust gas is sent from a combustion gas exhaust port 4 to a combustion gas exhaust pipe 10.
Further, the air is discharged from the exhaust blower 11 through a chimney-shaped exhaust pipe 12 to the outside. Also, the intake blower 17 is driven,
The warm air above the cabinet 7 is supplied to the intake pipe 14.
And heated through a heat exchange pipe 15 surrounding the outside of the chimney-shaped exhaust pipe 12. The sucked air passes through the supply pipe 16 and the intake blower 17, and is further guided through the inside of the combustion gas exhaust pipe 10 into the combustion chamber 1, where it is meandered and heated to a high temperature by the combustion flame 43 of the burner 6. Is done. The hot air heated to a high temperature is injected from an air blowing pipe 18 penetrating the bottom of the combustion chamber 1 into a rotating drum 25 serving as a drying and pulverizing chamber 24, and heats the garbage 41 that is rotating and stirring here. I do.

The garbage 41 introduced into the rotary drum 25 in this state is heated by the heat from the combustion chamber 1 heated by the burner combustion flame 43 and the high-temperature dry air injected from the air blowing pipe 18. It is rapidly heated and drying proceeds. When the rotating drum 25 formed in a hexagon rotates in the direction of the arrow as shown in FIG. 4, the garbage 41 is scraped up by the crushing blade 26, rises, and then falls while contacting hot air from above. . The protective cover 22 protects the combustion chamber 1 heated to a high temperature so that the garbage 41 does not directly touch and burn.

Further, the rotary drum 25 is
The high-temperature air injected into the inside heats and dries the inside garbage 41, so that the humidity becomes high. The humid air is discharged into the combustion chamber 1 from the powder ejection holes 20 and discharged to the outside through the chimney-like exhaust pipe 12 from the combustion gas exhaust port 4 together with the burner combustion flame 43.

As described above, the rotating drum 25 rotates and the garbage 41 is scraped up and agitated by the crushing blade 26, and the garbage 41 is heated by the heat of the combustion chamber 1 and the hot air flowing from the air blowing pipe 18. 41 is uniformly dried in a short time without unevenness.

In this case, a crushing blade 26 having projections having a triangular cross-section is continuously provided on the inner wall of a rotary drum 25 which is a drying and crushing chamber 24. As shown, the mountain-shaped crushing blade 26
And is crushed while moving upward to become finer. The garbage 41 that has moved upwards falls, and this operation is repeated, so that the garbage 41 is gradually dried and crushed to become finer. In this case, at the initial stage when the garbage 41 is charged, the rotation speed of the rotary drum 25 is set to a low speed of, for example, about 20 to 30 rotations / minute, and the combustion of the burner 6 is operated in a fully open state.

While the rotating drum 25 is rotating at a low speed, the burner 6 is fully opened and burned to heat and agitate the garbage 41. This state is detected by the temperature sensor 31 and the humidity sensor 32. When the temperature and humidity reach predetermined values, the control unit (not shown) reduces the combustion state of the burner 6 to about 30%, and the motor 36
Is set to a high-speed rotation of about 60 to 80 rotations / minute.

When the rotating drum 25 is switched to the high-speed rotation in this way, as shown in FIG. 5, the garbage 41 dried and pulverized is converted into a pulverizing blade 26 having projections having a triangular cross section continuously provided in a mountain shape. At high speed and crushed into fine powder. On the other hand, since the warm air is blown into the rotary drum 25 from the air blowing pipe 18, the garbage powder 42 which has been sequentially turned into fine powder soars into the rotary drum 25.
As shown in FIG. 6, the finely powdered garbage powder 42 that has risen and floated is injected into the combustion chamber 1 from the powder injection hole 20 opened in the left side plate 2 a of the combustion chamber 1, where the combustion flame 43 of the burner 6 is emitted. It burns instantly like a sparkler and is completely incinerated.

The garbage powder 42 in the form of fine powder is thus obtained.
Is supplied to the combustion chamber 1 sequentially, and the burner 6 and the garbage powder 42
Therefore, even if the combustion state of the burner 6 is reduced to a low level, the combustion of the fine garbage powder 42 can be continued. When all of the fine garbage powder 42 in the rotary drum 25 is burned in the combustion chamber 1, the operation is stopped.

According to experiments, the garbage disposer of the present invention has a
When 0 Kg of vegetable garbage 41 was treated, it could be completely incinerated and disappeared in about 4 hours. When the head of a thick tuna was treated, it could be completely incinerated and disappeared in about 6 hours. In addition, the skipjack could be eliminated in about 8 hours. When the blades of the exhaust blower 11 were inspected, it was confirmed that soot and the like did not adhere at all and the fine garbage powder 42 was completely burned.

In the above description, the case where the rotary drum 25 is formed in a hexagonal cylindrical shape is shown. However, other cylindrical shapes such as a pentagonal cylindrical shape, an octagonal cylindrical shape, and a cylindrical shape may be used. The rotating drum 25
Is not limited to an indirect rotation structure mounted on a roller, but may be a structure for directly rotating via a gear, and a rotary drive source is not limited to an electric motor, and a hydraulic motor may be used. The crushing blade 26 provided inside the rotary drum 25 is not limited to a continuous mountain shape, but may be of any other shape as long as it can scrape up the garbage 41 and crush it into fine powder. be able to. In addition, although the structure in which the intake pipe 14 is attached to the inside of the cabinet 7 and sucks warm air is shown, a structure in which the intake pipe 14 is attached to the outside and sucks outside air may be used.
