Description

[Detailed Description of the Invention] The present invention relates to a baffle device installed in the cavity of a hot water boiler for the purpose of providing resistance to the flow action of combustion exhaust gas and improving heat exchange efficiency.

As shown in FIGS. 16 and 17, conventionally, a horizontal baffle plate that covers the top (or bottom in some cases) of a cylindrical baffle 22 is fixed with a metal fitting 23 or the like by screws, etc. It was fixed to the baffle top 9 by a metal fitting 25.

According to such a configuration, a gap is required between the case inner body 2 and the baffle 22 for the exhaust gas to pass through, and therefore, the baffle device 24 does not vibrate in the combustion chamber 13 due to pressure during transportation or during combustion ignition. As a result, the baffle device 24, the nutty metal fittings 25, etc. may be deformed or fall by contacting the inner shell 2, resulting in an abnormal combustion condition.

Furthermore, according to this configuration, the baffle 22 has a cylindrical shape, so it takes up too much space for transportation, resulting in large losses.

Furthermore, as mentioned above, even if the baffle device 24 does not fall, the lower part of the baffle device 24 is not fixed to the combustion chamber 13 of the edge body, so it is rare for the baffle device 24 to become concentric with the combustion chamber 13, and the combustion state will not be normal. Something happened.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional art with a simple structure, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is a boiler edge body having an inner shell 2 and an outer shell 3.

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

A baffle top 9 is placed on a metal fitting 8 fixed to the inner body 3, and a baffle main body 11 is suspended from the baffle top 9 via a baffle metal fitting 10.

A burner 12 is provided on the side surface of the edge body 1, and the exhaust gas combusted in the combustion chamber 13 passes through the gap 14 between the baffle 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 draft regulator. 7 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.

FIG. 2 is a top view of an example of the baffle device of the present invention, and FIG. 3 is a side view thereof.

In FIG. 2, reference numeral 16 denotes a baffle forming a vertical portion, and two baffles are combined to form a cylindrical shape, and a baffle plate 17 is placed horizontally to form a box-shaped baffle device with one end open.

The baffle 16 and the baffle plate 17 are each fixed by various methods such as spot welding and fixing with screws,
It is fixed to the baffle top 9 by a baffle metal fitting 10.

In FIG. 2, 18 represents the inner surface of the inner shell 2 in FIG.

In Figure 1, combustion exhaust gas passes through the broken line, but the third
In the figure, the interior 1 of the baffle device is shown as a broken line.
9, and the inner shell 2 and baffle 1 from the opening 20 in the opposite direction.
It exits from the opening 15 of the buttful top 9 which passes through the space 14 between the holes 6 and 6.

Since the present invention can construct a baffle device with such a simple shape, it is advantageous in terms of cost, and is box-shaped, so it is strong.

Furthermore, since a plurality of baffles 16 are combined to form a vertical portion, it does not take up much space when transported as a single component.

Next, as shown in FIGS. 4 and 5, if each component is fixed with screws, it is possible to replace individual components instead of the entire baffle device during maintenance.

Next, FIGS. 6 to 9 show examples of application of the present invention.

A slit 26 is provided in the middle of the baffle 16, the ends of the baffle plates 17 are inserted into the slits, and a plurality of baffles are combined in a shape that sandwiches the baffle plates, and are fixed with screws or the like.

27 is a through hole of the baffle fitting.

In this example, in FIG. 7, the combustion exhaust gas passes through as shown by the broken line 28, and the positions of the baffle plates 1 to 17 determine the portions 29 and 29 that constitute the combustion chamber. The volume of each part 30 constituting the smoke chamber can be changed freely, and the position where the characteristics of the burner and hot water boiler are best can be selected.

Still other embodiments are shown in FIGS. 10 to 13, and in any of the configurations, when a plurality of baffles 16 form a vertical portion, the connection portion 31 of the vertical portion is connected to the inner wall of the inner shell. 18, the position of the baffle device is fixed within the combustion chamber 13, thereby preventing it from being deformed or falling due to vibrations during transportation or combustion ignition.

As can be seen from the above embodiments, the baffle device of the present invention connects a plurality of connecting parts between several plates forming a vertical part.
Since it is configured to be close to the inner wall of the cavity,
The position is determined by the contact between the connecting part and the inner wall of the cavity, and it can prevent deformation or damage due to vibrations during transportation or combustion ignition, and the connecting part itself is made of several plates that overlap each other. Since it is a part, it has strong strength and is not easily deformed, resulting in a stable positioning body.
