Abstract

PURPOSE: To collect combustion ashes with higher efficiency and without omission and enhance the operational safety during refuse disposal and dump easily piled up residues by forming a hopper-shaped ash sump area provided with a cover at the lower part of a refuse receiving screen member installed in an incinerator main body. CONSTITUTION: The refuse which is burned into ashes in an incinerator main body 10 drops from a screen member 22 and piled up one after another along a slope surface of an ash sump area 18 formed in the shape of a hopper from an opening 18a. When a definite amount of the refuse is piled up in the ash sump area 18, a cover 19 of the ash sump area 18 is opened by pedal operation and the ashes in the ash sump area 18 is automatically discharged outside by gravity. This construction makes it possible to discharge outside every bit of the incinerated ashes generated by the incineration from a small opening of the sash sump area 18. The pedal-type cover 19 enables the incinerated ashes to be discharged without causing burns even if the incinerated ashes are at a high temperature. It is also possible to remove the accumulated deposits on the screen member 22 with high efficiency.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator, and particularly to a metal incinerator which can be suitably used in general households and small factories.

[0002]

2. Description of the Related Art Conventionally, incinerators of various structures have been adopted as an incinerator for burning garbage generated in daily life.
Some are made of metal such as stainless steel, and some are made of bricks.

The basic structure of such an incinerator is provided with an incinerator main body for charging and burning dusts, and a peripheral wall of the incinerator main body is partially cut out to form an input port, and further incineration is performed. The furnace body is provided with a screen member and the like for receiving the introduced dust and improving the flow of air during combustion.

In such a conventional incinerator, since the incineration ash generated by combustion falls from the screen to the bottom of the incinerator, the incineration ash deposited on the bottom is discharged to the outside using a small scoop or the like. The work of scraping was necessary.

Therefore, for the purpose of improving the efficiency of scraping out such incinerated ash, for example, JP-A-6-323516 is used.
In the gazette, there is proposed an incinerator in which an ash receiving box for receiving incinerated ash generated by incineration is provided below the garbage receiver.

According to the incinerator disclosed in the publication, the ash after the incineration can be removed only by pulling out the ash receiving box from the ash removal port, so that the work can be performed easily and quickly, and the ash does not scatter. The surroundings are not polluted, and there is no need to provide a space or the like below the bottom portion, so that the volume of the main body can be increased, and the like.

[0007]

However, in the incinerator disclosed in the above-mentioned publication, since the ash receiving box is only arranged below the dust receiver, the incineration ash dropped from the dust receiver is completely ashed. There is a problem that it is not stored in the receiving box and easily overflows to the bottom of the incinerator body.

Further, when pulling out the ash container from the inside of the incinerator body, it is necessary to grasp the handle of the ash container with a hand, so that there is a risk of burns, especially in the case of incinerated ash that has not been burned for a while. There is.

Further, after long-term use, unburned or incombustible residue, large incinerated ash that does not pass through the dust receiver, etc. are deposited on the wire mesh-like dust receiver, and the dust receiver is clogged. May occur. In such a case,
In a conventional incinerator, it is necessary to insert a rod from the dust input port to pick up the remaining deposits, drop them from the dust receiver, and take them out to the outside, and to pick up incombustible substances such as empty cans from the top.

The present invention solves the above-mentioned problems in the conventional incinerator, and makes it possible to collect the combustion ash that has fallen from the dust receiver efficiently and without leakage, and to ensure the safety of the operation during dust discharge. It is an object of the present invention to provide a refuse incinerator which is improved and can easily discharge the residue accumulated on the refuse receiver.

[0011]

In order to achieve the above object, the waste incinerator of the present invention has a hopper-like ash provided with an opening / closing lid below a dust receiving screen member provided in the incinerator body. It is characterized in that a reservoir is formed. Here, the hopper shape means that a discharge opening is formed at the bottom of the container whose cross section decreases continuously from the top to the bottom,
The horizontal cross section may be circular or rectangular.

Here, as the opening / closing means of the opening / closing lid provided in the opening of the hopper-shaped ash reservoir, a pedal type opening / closing means that can be opened / closed by operating the legs without any manual operation is adopted. You can

Further, the front and rear ends of the screen member are rotatably supported, and a handle is provided on the rotating shaft to constitute a rotating means, whereby the screen member, which is conventionally fixed, can be turned upside down. .

[0014]

The dust that is burnt in the incinerator body and becomes ash drops downward from between the screen members, and is sequentially deposited from the opening along the inclined surface of the hopper that is formed like a hopper. When a certain amount is accumulated in the ash reservoir, the opening / closing lid of the ash reservoir is opened by pedal operation, and the ash in the ash reservoir is automatically discharged by gravity.

Further, when the incombustibles and the like remain on the screen member, they can be discharged to the outside from the ash reservoir by rotating the screen member about the horizontal axis and turning it upside down.
