Abstract

PURPOSE:To improve the efficiency of incineration by a method wherein a pair of air suction pipes is inserted into a combustion chamber from a top cover plate toward the bottom, and openings at the lower end of the pipes are formed so that the air introduced whirls along the inner wall surface of the combustion chamber. CONSTITUTION:A pair of air suction pipes 4 and 4' facing each other is inserted into a combustion chamber 1 from a top cover plate 2 toward a bottom plate 3, and an adequate distance is provided between the lower ends of the air suction pipes 4 and 4' and the bottom plate 3. The lower ends of the air suction pipe 4 and 4' diagonally cut to form openings 5 and 5' which open in the opposite directions each other and face the tangential direction of the inner circumference of the combustion chamber 1. The combustion air whirls in the regular direction along the inner circumference of the combustion chamber 1 due to te direction of the openings 5 and 5', so that enough combustion air required for incineration is uniformly supplied to items to be incinerated and a good incineration can be achieved.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is used to incinerate used telephone directories, magazines, slips, and other paper materials, as well as garbage such as food scraps, to improve the incineration efficiency. It is connected to the incinerator.

[Conventional technology]

Conventional incinerators have a structure in which a rostle (grate) is placed at the bottom of the combustion chamber, and combustion air taken in from the burner installation port is passed through the rostle into the combustion chamber to achieve combustion. Therefore, when a large amount of gold to be incinerated was stored in the combustion chamber, the intake of combustion air and the flow of air into the combustion chamber were insufficient, the heating temperature did not rise sufficiently, and the incineration efficiency was poor.

[Problem to be solved by the invention]

The present invention eliminates the h point that the prior art has, ie. Even when a large amount of material to be incinerated is stored in the combustion chamber, it is possible to take in the combustion air and distribute it thoroughly within the combustion chamber, and the heating temperature can be raised sufficiently, resulting in the incineration. The purpose is to provide an incinerator with good efficiency.

[Means for solving problems]

In order to achieve the above object, the present invention has devised a means for taking in combustion air into a combustion chamber and distributing it through three channels. The lower tips of the air suction pipes are arranged facing each other with an appropriate distance between them and the bottom plate of the combustion chamber toward the bottom plate. The openings are cut obliquely so that the openings are aligned along the inner peripheral wall of the combustion chamber so that the air introduced into each air intake pipe swirls in a predetermined direction along the inner peripheral wall of the combustion chamber. It is characterized by being formed in an open state. In order to adjust the intake amount of combustion air, the top plate of the combustion chamber has at least two air adjustment plates each having an intake hole that connects to at least one pair of air intake pipes arranged inside the combustion chamber. In some cases, they are arranged so as to be rotatable and overlap each other along the upper surface plate of the combustion chamber.

[For production]

In the present invention constructed as described above, regardless of the amount of incineration material stored in the combustion chamber, the combustion air is exhausted from the chimney inside the combustion chamber due to combustion, and the combustion air flows through the top plate of the combustion chamber. is introduced into at least a pair of air intake pipes opened to the outside of the combustion chamber, and is rotated in a predetermined direction along the inner circumferential wall surface of the combustion chamber through an opening at the lower end of the air intake pipes; Combustion air is sufficiently supplied to each part within the combustion chamber. In this case, if at least one pair of air adjustment plates having suction holes connected to the air suction pipe are arranged on the top plate of the combustion chamber so as to be rotatable, this will reduce the amount of material to be incinerated directed into the combustion chamber. The intake amount of combustion air is adjusted accordingly.

〔Example〕

An example of implementing the present invention will be described with reference to the attached drawings. Reference numeral 1 designates a combustion chamber of an incinerator, and within this combustion chamber 1, a pair of air suction vibrators 4 and 4' are disposed facing each other from a top plate 2 to a bottom plate 3. An appropriate space is provided between the lower end portions of the pipes 4, 4' and the bottom plate 3. t'fc, the lower ends of the air suction pipes 4, 4' form openings 5, 5' cut downward obliquely, respectively. (The air suction pipes 4 and 4' each have openings on the peripheral wall surface opposite to the lower tips thereof, and the opening surfaces thereof are oriented in a direction along the inner peripheral wall surface of the combustion chamber 1. 6 is combustion chamber 1
A chimney protrudes upward from the top plate 2, and the lower part of the chimney 6 is housed in an appropriate length above the combustion chamber 1. Reference numerals 7 and 7 designate a pair of air adjustment plates, each having a pair of intake holes 8 connected to the upper openings of the pair of air intake pipes 4 and 4', respectively;
8 and a chimney outlet 9, which are arranged overlappingly so that they can rotate along the upper surface plate 2 of the combustion chamber 1. By adjusting the position of each intake hole 8, 8 by rotating the button, a pair of air intakes can be created. Adjust the amount of air intake to Noyobu 4 and 4'. In the figure, reference numeral 10 indicates an incineration inlet for a garbage can provided at the upper side of the combustion chamber 1, and reference numeral 11 indicates an attachment port for a combustion device such as a burner provided at the lower side of the combustion chamber 1.

However, when using the incinerator according to the above embodiment,
After charging and storing materials to be incinerated such as garbage into the combustion chamber 1 through the input port and adjusting the opening area of the suction holes 8, 8 by rotating the air adjustment plates 7, 7 according to the amount accommodated, The material to be incinerated is heated and burned using a burner or the like. When the air is heated and combusted, the air inside the combustion chamber 1 is heated and raised along with the smoke and exhausted from the chimney, and the combustion air is drawn into the combustion chamber 1 from the outside through a pair of air intake pipes 4 and 4'. This combustion air is introduced into the combustion chamber 1 and swirls in a fixed direction along the inner circumferential wall surface of the combustion chamber 1 depending on the orientation of the openings 5 and 5' provided at the lower side of the air intake pipes 4 and 4'. Therefore, the combustion air necessary for incinerating the incinerated material is uniformly and sufficiently supplied to all parts of the combustion chamber 1, resulting in good combustion, and the combustion temperature reaches an extremely high temperature. Cabinet, chimney 6
Since it does not protrude upward from the top plate 2 of the Fi combustion chamber 1 and its lower part is located in the upper part of the combustion chamber 1 for an appropriate length, the incinerated materials are not fully combusted together with the smoke. 11
It is not immediately discharged to the outside from the chimney 6, but is sufficiently and completely combusted before being discharged to the outside.

〔Effect of the invention〕

Since the present invention is configured as described above, the drawbacks of the prior art described above are solved and the present invention has the following effects.

That is, in the combustion chamber, at least one pair of air intake pipes connected to the atmosphere through the top plate of the combustion chamber are installed from the top plate toward the bottom plate, with an appropriate distance between the lower tip and the bottom plate. Since they are arranged facing each other, even when a large amount of material to be incinerated is stored in the combustion chamber, unlike in the case of a conventional incinerator's rostre (grate), the air can be passed through the at least one pair of air suction pipes. This ensures that sufficient combustion air can be taken in. The lower end portions of at least a pair of air intake pipes are each opened downward in a diagonal manner, and the opening surface of each of the air intake pipes is opened in a predetermined rotation direction with respect to the inner circumferential wall surface of the combustion chamber. Since the air is directed along the inner circumferential wall surface, the air introduced from each air intake pipe is guided into the combustion chamber through the opening at the lower end, and circulates in a predetermined direction along the inner circumference of the combustion chamber. In this way, sufficient combustion air is uniformly and evenly supplied to the materials to be incinerated housed in the combustion chamber. Therefore, regardless of the amount of material to be incinerated that is stored in the combustion chamber, it burns well, and the combustion temperature reaches an extremely high temperature, resulting in good combustion efficiency. Therefore, in addition to documents such as slips, garbage, plants, etc., we also have to incinerate thick telephone directories that have traditionally been difficult to incinerate. It is also suitable for incinerating a large amount of magazines, books, etc. even if the button is pressed.

1. In the case where at least two or more air adjustment plates having suction holes connected to the air intake pipe are arranged on one top plate of the combustion chamber so as to be rotatable along the top plate of the combustion chamber, By adjusting the opening area of the air suction pipe to the atmosphere by rotating the air adjustment plate, the necessary and sufficient intake amount of combustion air can be adjusted according to the amount of material to be incinerated stored in the combustion chamber. It is possible to further increase the combustion efficiency.
