Description

[Detailed description of the invention] This invention is installed in a heat exchange cavity such as a hot water boiler,
The present invention relates to a buckle device that provides resistance to the flow action of combustion exhaust gas and improves heat exchange efficiency.

FIG. 1 shows a conventional hot water boiler, FIG. 2 shows its buckle device, and FIG. 3 shows a part thereof.

A is the boiler out of service, B is the burner fixed in the out of service, C is the exterior that covers the out of service, D is the top that covers the top of the out of service at the top of the exterior, E is the buckle device, F is the insulation material, and G is attached to the top. It is an exhaust port.

The circular buckle top H shown in FIG. 2 has four holes through which the connecting rod I is passed.

Below the buckle top H, a plurality of buckle plates J with one circular end cut out are provided through the connecting rod I, and a baffle spacer K for positioning is interposed between each buckle plate 110. .

A part of the baffle spacer has a cutout L, through which the connecting rod I passes.

Connecting rod to support the bottom baffle plate J■
The lowest end of the connecting rod I should be bent to prevent it from being pulled out.
The top end of the baffle is also bent to prevent it from coming off the baffle top.

According to this configuration, the end of the buckle plate J sag due to thermal deformation, and the suspension A in Figure 1 and the clearance M of the baffle play) J change, which changes the combustion state and lowers the efficiency. .

Also, the combustion exhaust gas meanderes in a wide direction as shown by arrow N.
Exhaust resistance is large, leading to loud ignition noise.

Furthermore, each part is configured to move freely, and the overall height dimension restrictions change depending on the state of the upper bend O of the connecting rod I, which tends to create gaps between each part, which are caused by the flow of combustion exhaust gas. There were drawbacks such as vibration and deformation of various parts.

The present invention is intended to eliminate such drawbacks of the conventional art, and one embodiment thereof will be described below with reference to the drawings.

FIG. 4 shows a hot water boiler according to an embodiment of the present invention, and FIGS. 4 to 9 show its buckle device.

In the figure, the boiler 1 is out of service and is composed of an inner shell 2 and an outer shell 3. Water enters the space between the inner and outer shells 2 and 3, and the space inside the inner shell 2 is used for combustion and heat. It becomes an exchange space.

4 is an exterior, 5 is a top, which has an exhaust port 6, and a draft regulator 7 is attached to the upper part of the top 5.

A buckle top 9 having the shape shown in FIG. 8 is placed on the metal fitting 8 fixed to the inner body 3, and the panful main body 11 is suspended from the baffle top 9 via the hanging metal fitting 10 having the shape shown in FIG. ing.

A burner 12 is installed on the side of the suspension 1, and the exhaust gas combusted in the combustion chamber 13 passes through the gap 14 between the buckle body 11 and the inner shell 3, as shown by the broken line, from the opening 15 of the baffle top 9 to the exhaust port 6 and the tract regulator I. It passes through and is discharged to the outside.

In order to improve heat exchange efficiency, it is necessary to pass as much exhaust gas as possible as close to the inner shell 3 as possible and in as turbulent a state as possible.

On the one hand, it is required to construct such a mechanism as cheaply as possible.

In FIGS. 4 to 5 showing the baffle body of the present invention,
Reference numeral 16 denotes a baffle forming a vertical portion, which is constructed by combining two L-shaped plates into a rectangular frame shape.

1T is a multi-stage cut-and-raised portion cut and raised from each side of the panful 16.

Reference numeral 18 denotes a baffle plate which has protrusions on each side to be placed on the raised portions 17 and is arranged in multiple stages within the baffle 16.

The baffle plate 18 is placed on the cut-out portion 17 and arranged in the horizontal direction A, and the internal cavity 1 in the baffle 16
Block 9.

This prevents the combustion exhaust gas from flowing through the cavity 19 and the openings 20 formed by the cut and raised parts 17 of the baffle 16, and also allows each cut and raised part 17 to have a gap with the inner shell 2. 14 and disturb the combustion exhaust gas, the heat exchange efficiency can be increased.

The baffle and buckle plate may be fixed in spots, but as shown in Figure 2, if a slit 21 is provided in the vertical plane of the panfle 16 so that it is flush with the cut-out part 17, and the baffle and buckle plate are fixed in this way, distortion due to thermal expansion can be prevented. can.

It should be noted that the buckle plates 18 do not necessarily need to be provided 1 to 1 with respect to the cut-out portion 1T, and may be provided every other buckle plate, or may be provided only at the top, middle, and bottom stages, and the buckle plates 18 may Determined according to characteristics.

Furthermore, if the cutting mold is designed to cut only one piece, the number of cuts can be changed as needed.

As described above, according to the configuration of the baffle device of the present invention, the exhaust resistance can be changed freely, which is very effective in terms of sharing parts or molds.

As mentioned above, the baffle device of the present invention has a high heat exchange efficiency, and since the exhaust gas passes in a substantially upward direction as shown by the broken line in FIG. 1, the exhaust resistance is not large and does not adversely affect combustion.

In addition, by making the baffle box-shaped, it has greater strength, and since the baffle plate installed horizontally has protrusions that rest on the cut-out parts, it is less likely to be deformed by heat, and therefore the performance will not change. do not have.
