Description

[Detailed description of the invention] This invention relates to an improvement of an incinerator using a drum can.

An inexpensive and high-performance incinerator using a drum can was already proposed by the present applicant in Publication of Utility Model Publication No. 50-25576.

By the way, when a drum can is used as an incinerator, a window is provided at the bottom of the drum can to take out ash dust, etc., and combustion materials are introduced from the top, and a chimney is connected to the top.

For this reason, it is necessary to provide a loading opening that can be opened and closed at the top of the drum can, but this opening must be able to be opened as wide as possible, and the structure for opening and closing must be simplified to reduce assembly costs.

As for the mounting structure of the opening provided in the upper part of the incinerator and the lid that opens and closes this opening, for example, as shown in Japanese Utility Model Application Publication No. 49-86676, a flat plate lid is attached to the furnace with a pivot or a hinge. It is known that this was done.

By the way, the structure for attaching the lid as described above requires a separate pivot and hinge, which leads to an increase in assembly cost due to an increase in the number of component parts.

This idea was made in view of the above points, and by simply modifying the hood with an opening and the lid that opens and closes this opening, the lid can be attached to the opening, and the lid can be attached with a pivot point. The purpose is to provide an incinerator that does not require the use of other parts such as hinges and hinges, and can reduce assembly costs.

The structure of this device is a cylindrical furnace body, a hood that covers the top of the furnace body and has a chimney connected to the rear of the top end, and is attached to an opening provided in the front of the hood to open and close the opening. The hood consists of a small-diameter cylindrical upper half to which a chimney is connected to the upper end, a middle part that extends forward from the lower end of the upper half, and a lower edge of the middle part. a large-diameter lower part that fits externally into the upper part of the furnace body, and a lower widening opening is provided in the first half of the intermediate part from the large-diameter lower part to the upper half of the furnace body, and The lid has a semi-cylindrical cross section that can fit into the opening shape of the hood to close the opening, and the lower part of the lid has a recessed notch on both side edges of the hood. A flange that abuts the inner surface of the hood is provided on the removed portion and the upper edge, and a flange with a large protrusion that abuts on the outer surface of the hood is provided at the lower part of both side edges of the lid, and a flange with a large protrusion is provided at the upper end of the flange with a large protrusion. The formed protruding step portion is fitted into openings provided on both sides of the opening so as to serve as a fulcrum for opening and closing movements.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the incinerator body 1 uses a drum can, the upper edge of which is opened by removing the top cover, and a large number of small holes for air intake are bored in the lower bottom wall, and ash dust etc. are taken out from the lower front of the peripheral wall. It is formed with a window 2 that can be opened and closed.

The incinerator main body 1 is set on a leg stand 4 with an open front provided on a base plate 3.

On the base plate 3, there are support frames 5 on both sides sandwiching the incinerator main body 1.
A hood 6 is installed between both support frames 5 to cover the upper half of the incinerator body 1 set on the base plate 4. A chimney 7 connected to the upper end of the hood 6 is mounted on the base plate 3 It is supported by a column 8 erected at the rear of the frame.

The hood 6 has a semi-cylindrical lower part 9 that fits over the rear half of the incinerator main body 1, and a cylindrical shape having a diameter of about one-third of the lower part 9. an upper half 10 disposed so as to be on the same line vertically as
1.

As shown in FIG. 2, the intermediate portion 11 has an opening 12 that widens downward on the front side, and a semicircular notch that is an extension of the opening 12 is formed at the lower front of the upper half 10. 22
is provided.

The lower part 9 of the hood 6 is designed to fit over the rear half of the upper part of the incinerator body 1 set on the pedestal 4, so that the incinerator body 1 can be attached to and removed from the pedestal 4 from the front. Can be performed freely from the side.

The opening 12 of the hood 6 can be opened and closed by a lid 13 that is detachably attached to the hood 6.

The lid 13 is formed of a semi-cylindrical part 14 that fits externally into the upper half of the incinerator body 1, and a tapered wall 15 that is continuous from the upper edge of the semi-cylindrical part 14 and has a semi-cylindrical cross section whose upper end gradually becomes smaller in diameter. When the semi-cylindrical part 14 is fitted into the incinerator 1, both sides fit into both side edges of the opening 12, and the upper end of the tapered wall 15 fits into the notch 22.

Flanges 16 and 17 projecting outward are provided at the upper end and both side edges of the tapered wall 15 of the lid 13, respectively, and flanges 17 are provided at the lower end sides of the both side edges near the semi-cylindrical portion 14.
The protruding step portion 1 is formed by the flange 18 having a larger protrusion amount than the
9 is formed.

Furthermore, recessed notches 20 into which the protruding step portions 19 fit are provided at positions corresponding to the protruding step portions 19 on both side edges of the hood 6.

When the lid 13 is attached to the hood 6 and the opening 12 is closed,
As shown in FIG. 3, the flanges 16 and 17 are in contact with the inner surface of the hood 6, and due to the engagement of the protruding step part 19 and the recessed part 20, the flange 18 is brought into contact with the upper surface of the hood 6 as shown in FIG. ing.

When the lid 13 is in the closed position as described above, its center of gravity is located on the lower end side than the protruding step portion 19, and therefore the lid 13 tends to slide down along the slope of the hood 6 due to the seven langes 18. shall be.

However, since the flanges 16 and 17 are located on the inner surface of the hood 6, this is prevented, and the state in which the lid 13 covers the upper half of the incinerator body 1 and closes the opening 12 is maintained.

The lid 13 has a protruding step part 1 supported by a recessed part 20.
9 as a fulcrum, it can be freely rotated in the direction of opening the opening 12.

That is, when the handle 21 provided on the front surface of the semi-cylindrical part 14 is pulled up, the lid 13 rotates around the protruding step part 19, and the upper part and opening of the incinerator body 1 are opened.

At this time, since the end of the flange 17 fits into the recessed notch 20, the lid 13 does not move below the hood 6, and the lid 13 is formed in a semi-cylindrical shape. Since this is inverted within the opening 12, the dust charging space leading from the opening 12 to the incinerator main body 1 is wide open, and the dust charging operation can be performed easily.

Further, when the lid 13 is erected so that its center of gravity is positioned rearward with respect to a vertical line passing through the protruding step portion 19, the inverted state is automatically maintained.

Although the flange 18 provided on the lid 13 has been shown as having a wide width as a whole, as shown by the dashed line in FIG.
The incinerator of this invention, which may be formed thinly with the protruding step part 19 left, has the above-mentioned structure. Attach the lid 13 to 6.

To introduce dust into the incinerator body 1, it is sufficient to turn the lid 13 upside down and open the opening 12 as shown in FIGS. 6 and 7.
During combustion, the opening 12 may be closed by laying down the lid 13 as shown in FIGS. 1 to 3.

Moreover, the operation of removing the incinerator main body 1 from the top of the pedestal 4 can be performed by removing the lid 13 from the hood 6.

As described above, according to this invention, the hood, which covers the upper part of the cylindrical furnace body and has a chimney connected to the upper end, has a semicircular arc shape extending from the large diameter lower part to the first half of the middle part, with the upper end being the upper half. An opening in the lower floor is provided, recessed parts are formed on both sides of the middle part of this opening, and a lid having a semi-cylindrical cross section that fits into and closes the opening is provided with a lower part on both sides of the lid. A flange that abuts the inner surface of the hood is provided on the removed portion and the upper edge, and a flange with a large protrusion that abuts on the outer surface of the hood is provided at the lower part of both side edges of the lid, and the upper end of the flange with a large protrusion is provided. Since the formed protruding step portions are fitted into the openings on both sides of the opening and serve as fulcrums for opening and closing, the lid can be freely opened and closed with respect to the opening of the hood by fitting into the openings on both sides of the opening of the cord. This can be done by the flange of the lid, and there is no need for a separate pivot or hinge for attaching the lid, reducing the number of components and lowering assembly costs.

In addition, the lid is formed in a semi-cylindrical shape and opens around the protruding step part of the flange, keeping the opening open when it is inverted, so the opening can be left wide open when dust is being introduced, and the lid can be closed during the loading operation. A side effect is that there is no need for any action to hold the holder in the open position.
