Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuse incinerator for garbage such as garbage that can be incinerated.

[0002]

2. Description of the Related Art Small incinerators for household use can only be incinerated directly (self-incinerating). For this reason, it was difficult to incinerate water-containing materials such as kitchen waste. Therefore, kitchen waste is collected by public institutions and disposed of at large public treatment facilities. Such a treatment facility is a large external energy-dependent incinerator.

[0003]

However, since garbage is regularly collected by public institutions and the like, it is necessary to store it at home or the like for a short period of time. In addition, since kitchen waste emits a bad odor, it is desired to dispose of it quickly. On the other hand, in the large incinerator, the incineration cost is high. In addition, there is a method of refrigerating and storing the garbage etc. in order to eliminate the bad odor of the garbage etc. However, the cost is high and the amount of garbage to be processed is not reduced. Therefore, it is an object of the present invention to provide a compact incinerator capable of incinerating kitchen waste or the like to form ash.

[0004]

In order to solve the above problems, the present invention has the following constitution. That is, an incinerator that heats by an external heat source such as a heater to incinerate garbage such as kitchen waste, an input port for charging garbage such as kitchen waste into the incinerator, and a radial shape that rotates along the inner bottom surface of the incinerator. It is characterized by comprising a rotary blade having a wing and a drive device for driving the rotary blade to rotate forward and backward. Also, bend the tips of each rotary blade in the same direction so that when the rotary blade is rotated in the bending direction, the garbage etc. enters inward, and when it is rotated in the opposite direction, the garbage etc. is pushed outward. Is preferred. Further, the air supply cylinder is formed in an inverted U shape, and one end of the air supply cylinder enters from the lid of the incinerator,
The other end may be located outside the incinerator.

[0005]

[Operation] The operation will be described. Garbage such as kitchen waste is put into the incinerator from the charging port, and the garbage such as kitchen waste is agitated by the rotary blades and heated by the heat source to incinerate the garbage such as kitchen waste in the incinerator. Also, bend the tip of the rotary blade so that
When it is rotated in the right direction (forward rotation), garbage such as kitchen waste tries to enter inward, and when it is rotated in the reverse direction, garbage such as kitchen waste is pushed outward. In this way, by rotating the rotary blades in the forward and reverse directions, it is possible to efficiently stir and incinerate. Air is supplied through an air supply tube when incinerating garbage such as kitchen waste.

The lower end of the hopper 20 has a first opening 18
The upper end of the hopper 20, which is connected to a, is formed in a funnel shape and opens. Further, double lids 40 and 41 are provided on the upper part of the hopper 20 so as to be opened and closed. The lids 40 and 41 are provided separately from each other, one lid 40 covers the opening of the hopper 20, and the other lid 41 is the neck 20.
It is provided between a and the lid 41. Each lid 40,
The structure 41 is a conventionally known opening / closing structure that can be opened horizontally. The hopper 20 is provided with a double lid in order to prevent smoke from leaking and prevent heat from being transmitted.

A heater and a platinum catalyst (not shown) are built in the middle of the chimney 22 and a deodorizing portion 23 for removing a bad odor contained in the smoke is provided.

The air supply cylinder 24 has an inverted U-shape on the side surface (see FIG. 3), and one end of the air supply cylinder 24 extends from the third opening 18c to the incinerator 14.
It is the discharge side 24a that has entered inside, and the other end is the suction side 24b that is located outside the incinerator 14 and that takes in air. The tip of the suction side 24b of the air supply cylinder 24 is the discharge side 24.
It extends L downward from a. This is to prevent backflow of the air sucked from the suction side 24b of the air supply cylinder 24 and supplied into the incinerator 14.

On the side surface of the incinerator 14, there is provided an outlet 14a for taking out ash after incineration of garbage such as garbage. The outlet 14 a is covered with an opening / closing lid 42 and can be opened / closed via a hinge 43. Further, in order to scrape out the ash from the outlet 14a, an ash tray 44 is provided following the outlet 14a. The ash taken out on the ash take-out tray 44 may be appropriately stored in a container. Also, ash tray 4
The reference numeral 4 extends from the side surface opening 12 a on the side surface of the casing 12 to the outside of the casing 12.

Next, a method of using the refuse incinerator of the above embodiment will be described. (1) The double lids 40 and 41 of the hopper 20 are opened, and garbage such as kitchen waste is put into the incinerator 14 to remove the lids 40 and 41.
Close. (2) When the power is turned on, the heater device 16 is energized and the wings 36 start rotating.

(3) The wings 36 are rotated in the direction of the tip of the arc portion 37 of the wings 36 (direction of arrow A: forward rotation). Then, garbage such as kitchen waste rotates together with the wings 36 in a state of being divided into five between the wings 36. It should be noted that dust such as kitchen waste is pushed by the side surface 36a of the wing 36 and agitated. Further, since the arcuate portion 37 is oriented in the rotation direction, dust such as garbage is pushed inward by the inner side surface 37a of the arcuate portion 37 and tries to sequentially enter inside.

On the other hand, when the wings 36 ...
By b, garbage such as garbage is pushed out to the outside one by one.

While the normal rotation and the reverse rotation of the wings 36 are alternately repeated, the garbage such as garbage is incinerated. That is, by alternately repeating the normal rotation and the reverse rotation of the wings 36, it is possible to agitate the dust such as the garbage on the center side and the dust such as the garbage on the outside, and at the same time, the incinerator 14
As the dust on the bottom side moves, the dust on the top also moves by stirring. Therefore, it is possible to efficiently incinerate garbage such as garbage in the incinerator 14. Since the blades 36 ... Of the rotary blades are radial, dust such as garbage is pushed out and acts synergistically with the action of the arc portion 37.

(4) Since garbage such as kitchen waste in the incinerator 14 is heated to a high temperature while being stirred, it is incinerated while being dried. As for the supply of the outside air to the incinerator 14, the outside air naturally flows from the air supply cylinder 24 by the suction force of the chimney 22. Further, the malodorous vapor evaporated in the incinerator 14 is deodorized by the deodorizing portion 23 of the chimney 22 and discharged to the outside. The odor inside the chimney 22 may be burned by a burner (not shown) so as to be substantially odorless.

(5) When the incineration of garbage such as garbage in the incinerator 14 is completed, the power supply to the heater device 16 is cut off. Then, it waits for the temperature in the incinerator 14 to drop. (6) When the temperature inside the incinerator 14 decreases, open the opening / closing lid 42 on the side of the incinerator 14, and remove the ash tray 4 from the outlet 14a.
4. Take out the ash after incineration of garbage such as garbage on the top. At this time, by rotating the wings 36 in the reverse direction, the ash is pushed out in the outer diameter direction, and the ash can be taken out easily.

As shown in (1) to (6) above, the wing 36.
The rotation direction of, and the energization of the heater device 16 are controlled by the controller by known electric means.

In the above embodiment, the wings 36 ...
Although 5 are provided, the number is not limited. However, when the number of wings 36 ... is small and there are two, garbage such as garbage is divided into two, and garbage such as garbage always exists on the back side of the direction of rotation of the feathers 36. It will not be done, and the efficiency of processing garbage such as garbage will be low. For this reason, it is preferable that the number of wings 36 is increased as in the above-described embodiment, and that garbage such as kitchen waste is in large contact with the bottom surface of the incinerator 14. Further, when the number of wings 36 is large, dust such as kitchen waste comes into contact with the bottom surface of the incinerator 14 heated to a high temperature while being sequentially stirred, so that the incineration efficiency can be improved.

A blower 25 may be provided in the air supply cylinder 24 to forcefully feed air. That is, air may be supplied from the suction side 24b of the air supply cylinder 24 by the blower 25. By doing so, sufficient air is supplied to garbage such as kitchen waste, and rapid incineration becomes possible.

The garbage such as kitchen waste in the above-mentioned embodiment means a material which contains a large amount of water and is difficult to ignite. Further, in the above embodiment, the heater device 1 is used as the heat source of the incinerator 14.
Although 6 is used, an energy heat source such as gas or oil may be used instead of the heater device 16. Although various explanations have been given with reference to the preferred embodiments of the present invention, many modifications such as the shapes and configurations of the hopper, chimney, and air supply cylinder of the present invention can be made without departing from the spirit of the invention. Of course.

EFFECT OF THE INVENTION Since the garbage incinerator according to the present invention is constructed as described above, it is possible to quickly incinerate the garbage such as garbage that gives off a bad odor to make it odorless.
Therefore, the volume of ash is less than the volume of garbage such as garbage,
Subsequent processing is also easy. Also, bend the blades so that the tips of the rotating blades are slanted in the same direction, and rotate the rotating blades in the bending direction to allow garbage such as garbage to enter the inside, and rotate it in the opposite direction to remove garbage such as garbage. Since the dust is pushed outward, it can be efficiently stirred and can be efficiently incinerated. The air supply cylinder is formed in an inverted U shape, one end of the air supply cylinder enters from the lid of the incinerator, and the other end is located outside the incinerator, so that suction of air flows backward into the incinerator. It has a remarkable effect that it can be performed without any trouble.
