Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a boiler in which a baffle plate disposed inside a furnace cylinder can be pulled out.

Conventionally, small boilers used for bathtubs and the like have water pipes installed in a meandering manner inside the furnace cylinder.

However, installing a long water pipe in a meandering manner would complicate the structure, so it is simplified by shortening it. Therefore, heat loss is large and effective heat exchange is not performed. In addition, because the water pipe was fixed inside the furnace cylinder, it could not be pulled out through the narrow fire opening, making assembly, repair, and cleaning of soot troublesome. In addition, some large boilers are built with bricks built inside and bent bonito paths to serve as baffles, but these baffles do not provide any heat exchange surfaces, so thermal efficiency is not improved much, and as mentioned above, Similarly, because the baffle plate could not be pulled out, it was a pain to clean the soot, clean it, and remove it.

In view of this point, the present invention has been developed by removing the cover plate that removably closes the closing part of the furnace cylinder, so that the baffle plate and water tube inside the furnace cylinder can be pulled out of the furnace cylinder, allowing assembly and repair of the inside of the furnace cylinder, and soot removal. To provide a boiler which can be easily cleaned and has improved heat exchange efficiency by forming a passageway inside a hollow lid plate.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 to 3 show one embodiment of the present invention. In the figure, 1 is a water tank, and this water tank 1 is formed in a substantially cylindrical shape.

Inside this water tank 1, a furnace cylinder 2 in the shape of a truncated hollow cone is provided laterally, and one end thereof closes at the front side of the water tank 1 to form an opening 3. A lid plate 4 in the shape of a hollow disk is removably provided in the opening 3 so as to close the opening 3, and a water passage 5 is formed inside the lid plate 4.

Further, a fire opening 6 is provided at the bottom of the lid plate 4. 7
A, 7B, and 7C are baffle plates in the shape of hollow discs, which are arranged in the vertical direction at intervals within the furnace cylinder 2.
A and 7C have a cutout at the top center as shown in FIG. 3, and the middle baffle plate 7B, on the contrary, has a cutout at the bottom center to form a zigzag flue 8 up and down. .

Also, like the cover plate 4, a water passage 5 is formed inside these baffle plates 7A, 7B, and 7C. A plurality of water pipes 9 are connected perpendicularly to the cover plate 4 and the baffle plates 7A, 78, 7C to connect them together and to make each water passage 5, 5 suitable for a lotus.

A hot water rising pipe 10 extends from the upper part of the outer surface of the cover plate 4, and is fitted to the upper part of the water tank 1, and is detachably connected to the upper part of the water tank 1 with a bolt or the like.

Further, at the bottom of the baffle plate 7C, a cold water rising water pipe 11 is provided which extends through the side surface of the water tank 1 and conveys the cold water to the water tank 1 again on the outer surface of the lower part of the water tank 1. They are removably connected.

In the figure, 12 is a chimney provided at the tip of the furnace tube 2 through the side of the water tank 1, 13 is a water drain pipe, and 14
A indicates cold water, and 14B indicates hot water.

Next, to explain the operation of the above-mentioned horizontal boiler, when lime, heavy oil, etc. are burned from the firing port 6, hot smoke is generated in a zigzag shape up and down along the flue 8 formed by the baffle plates 7A, 7B, and 7C. It bends to advance inside the furnace tube 2 and is discharged from the chimney 12 at the tip.

On the other hand, the cold water 14A in the water tank 1 sinks downward, passes through the cold water rising water pipe 11, is guided to the baffle plate 7C, and is further led to the cover plate 4 through the water pipe 9 that is suitable for this, and the baffle plates 78, 7C. During this time, the hot water is heated and becomes hot water 14B, which then flows into the upper part of the water tank 1 through the hot water rising pipe 10.

Therefore, a zigzag-shaped flue is formed by the baffle plates 7A, 7B, 7C, and the baffle plates 7A, 7B, 7
Since the water passage 5 is formed inside C, heat exchange is performed effectively.

Furthermore, since the cover plate 4 also has a water passage 5 formed inside,
Heat exchange also takes place on this side of the bonito path. In addition, when performing assembly, repair, or cleaning of soot in the dust path, by removing the bolt at the connection part provided between the hot water rising water pipe 10 and the cold water rising water pipe 11, the connection to the diamond plate 4 can be made. The baffle plates 7A, 78, 7C and the water tube 9 can be easily pulled out from the closed part 3 of the furnace cylinder 2, thereby improving workability.

As explained above, according to the boiler according to the present invention, a lid plate is provided that removably closes the entrance part of the furnace cylinder, and by removing this lid plate, the baffle plate and the water pipe can be pulled out to the outside. This improves the workability of cleaning, repairing, and cleaning soot, and since a passageway is formed inside the lid plate, heat exchange efficiency can be greatly improved compared to conventional structures.
