Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an incinerator for incinerating waste, paper, cardboard, plastic, etc. generated in factories and homes.

[0002]

[Prior art]

 In the conventional incinerator, a chimney was attached to the smoke outlet of the incinerator, and the incineration ash was dropped onto a fixed floor below the grate or on an ash tray.

[0003]

[Problems to be solved by the device]

 In a conventional incinerator, the introduction of air into the incinerator is obstructed by the materials to be incinerated, ash, etc., and is emitted from the stack with incomplete combustion, so black smoke, soot, and unburned matter are emitted. The surrounding environment was dirty. There was also the problem that ash discharge could not be done smoothly. The problems to be solved by the present invention are to solve these problems in the past, to improve the combustion state, to discharge combustion gas in a clean state without black smoke, soot, and unburned matter, and to remove ash. It is to provide an incinerator that facilitates the collection and transportation of waste.

[0004]

[Means for Solving the Problems]

 The gist of the present invention which solved such a problem is as follows: 1) In the incinerator in which a chimney is provided in the upper part of the incinerator body and a loss is provided in the incinerator body, the lower part of the incinerator body is opened, and An ash collection box that collects ash that can be taken in and out is stored inside the lower part of the incinerator body, and an air passage is provided between the side wall surface of the ash collection box and the inner wall of the incinerator body above the lower opening of the incinerator body. The incinerator is characterized by being formed. 2) The incinerator according to 1) above, wherein the heat-resistant ash storage bag is attached along the inner wall of the ash recovery box in an open state.

[0005]

[Action]

 In this invention, air is mainly introduced through the lower opening of the incinerator and rises through the air passage between the side wall of the ash recovery box and the lower inner wall of the combustion furnace. The air passes through the roster and flows up along the inner wall of the combustion furnace as an updraft. Since the inner wall of the combustion furnace is heated by heat transfer / radiation heat and has a high temperature, air is preheated by passing through this air passage, the temperature of the air rises and the force of the ascending air flow is strengthened to increase the air suction force, A large amount of air is sent into the combustion furnace. Wastes, paper, cardboard, plastics, etc., which serve as fuels on the rustle in the main body of the combustion furnace, are often burned by the ascending air, and the combustion gas is released from the chimney to the atmosphere. On the other hand, the residue and ash burned in the main body of the incinerator fall into the ash recovery box below through the rustle, so the ash can be easily collected by pulling out the ash recovery box from the incinerator, and it can be transported as it is. You can do it. In particular, in the case where a heat-resistant ash storage bag is attached to the inner wall of the box, it is possible to move and dispose of ash cleanly and quickly by pulling out the bag after pulling out the ash collection box.

 Embodiments of the present invention will be described below. The embodiment shown in FIGS. 1 to 4 is characterized in that a smoke exhaust tube and an air introduction tube are provided in the lower portion of the chimney, and a wheel is provided to allow the ash collection box to freely move in and out and a heat-resistant ash storage bag is laid. This is an example. Further, FIG. 5 shows another example of the structure in which the chimney lower part structure of the embodiment is composed of a chimney and a smoke exhaust pipe, and no air inlet pipe is provided. 1 is a partially cutaway front view of the embodiment, FIG. 2 is a vertical side view of the embodiment, FIG. 3 is a plan view of the embodiment, FIG. 4 is an enlarged vertical sectional view of a lower portion of the chimney of the embodiment, and FIG. It is an expanded longitudinal cross-sectional view of a structural example.

In the figure, 1 is an incinerator, 2 is a chimney, 3 is an incinerator body, 4 is a smoke outlet, 5 is a smoke exhaust pipe, 6 is formed between the inner surface of the lower part of the chimney and the outer wall of the smoke exhaust pipe. A circular air passage, 7 is a rustle provided at a slight downward slope toward the input door 17, 8 is an ash recovery box, and 9 is formed between the side wall of the ash recovery box and the lower inner peripheral wall of the incinerator body 3. Air passage, 10 is an air hole perforated in the smoke exhaust pipe 5, 11 is an air introduction pipe, 12 is an air hole perforated in the air introduction pipe, and 13 is a heat-resistant ash storage laid inside the ash collection box 8. A bag, 14 is a lower end opening provided at the lower end of the chimney 2 and communicating with the air passage 6, and 15 is an opening provided at the lower end of the incinerator body 3, which communicates with the air passage 10. Reference numeral 16 is a baffle plate provided below the smoke exhaust port 4 inside the incinerator body 3, 17 is a loading door for loading the burned material into the incinerator body 3, and 18 is a front portion projecting from the support frame of the loss 7 Further, a rostrul swing rod, 19 are wheels of the ash collection box 8, and 20 is a handle of the ash collection box 8. In the embodiment shown in FIGS. 1 to 4, waste such as paper, cardboard, plastic, etc. is thrown into the incinerator body 3 by opening the throw door 17. When the waste is ignited and burned, an ascending air current is generated by the heat of combustion, and the wall temperature of the incinerator body 3, the stack 2, the smoke exhaust pipe 5, the air inlet pipe 11 and the like also rise, The air is introduced so as to be sucked from the opening 15 at the lower end of the incinerator main body 3, passes through while being heated in the air passage 9 between the inner surface of the lower part of the incinerator and the side wall surface of the ash recovery box 8, and passes through the incinerator main body 3 It is sent to the inner upper part. The flow of air along the inner peripheral wall of the incinerator body 3 becomes a strong upward flow, and sufficient air necessary for combustion is supplied into the incinerator body 3.

After being burned in the incinerator main body 3, the combustion gas and smoke are sent by the baffle plate 16 to the inside of the smoke exhaust pipe 5 through the smoke exhaust port 4 while being circumvented and burned well. . Here again, the ascending airflow in the chimney 2 sends the air to the air passage 6 so as to be sucked from the lower end opening 14, is heated, and is sent from the air hole 10 of the smoke exhaust pipe 5 to the center of the chimney. This replenished air causes unburned and incompletely burned materials to burn again inside the smoke stack 5 and the upper portion of the stack 2, and is discharged from the stack 2 to the atmosphere without any unburned and incompletely burned materials. It The emission of soot and black smoke was eliminated by this.

Further, in the first embodiment, the upright portion of the air introduction pipe 11 is inside the smoke exhaust pipe 5 inside the chimney 2, is exposed to high temperature combustion gas, and the pipe wall is heated to high temperature. Since there is a strong upward airflow in the center of the chimney 2, the air inside the air introducing pipe 11 flows out so that it is sucked out of the pipe, and the outside air is strongly sucked through the opening at the end of the air introducing pipe 11. Then, a large amount of air is supplied to the center of the chimney 2. Therefore, strong secondary combustion is performed on the outer periphery of the air introduction pipe 11 to bring it into a complete combustion state.

The ash / residue after combustion is stored in the ash storage bag 13 of the ash recovery box 8 below the rust 7 or after falling. Since the rustle 7 has a downward slope toward the closing door 17, it is easy to take out cans. For the ash recovery, the ash / residue on the rustle 7 can be well dropped into the ash storage bag 13 below by rocking the rocker swing rod 18 up and down. After that, the ash recovery box 8 is pulled out from below the incinerator main body 3, and the wheels 19 move it to a required place for disposal. At this time, since the ash storage bag 13 can be bound and packed in the ash storage bag 13 for disposal, the ash can be easily discarded and transported.

The chimney lower structure shown in FIG. 5 is an example in which the air introduction pipe 11 is not provided inside the smoke exhaust pipe 5. In this example, the air is introduced and burned in the same manner as in the embodiment except that the air supply pipe 11 does not supply air at the center of the smoke exhaust tube 5. The above-described embodiment can burn more completely than this embodiment.
