An embodiment of the present invention will be described. FIG. 1 is a side view of a buried snow melting apparatus of the present invention, FIG. 2 is a side cross sectional view of the buried snow melting apparatus, FIG. 3 is a side cross sectional view showing a storage configuration of a chimney, and FIG. , FIG. 5 is a front sectional view when the chimney is stored, FIG. 6 is a front sectional view when the chimney is used,
FIG. 7 is a plan view of a chimney portion.

1 and 2, the entire configuration will be described. In this embodiment, the inside of the snow melting tank 2 is separated into three burner rooms E, a snow melting room C, and a hot water melting room M by a burner mounting plate 25 and a hot water melting room shielding plate 8.
The burner B is arranged inside the. In addition, snow melting room C
A snowmelt cylinder A is arranged inside the box. Then, the combustion portion 1 protruding from the burner B is fitted into the snow melting tube A so as to penetrate the burner mounting plate 25. The snow melting cylinder A
Is supported by supports 10 and 11 from below, and is supported in a floating state.

In the hot water snow melting room M, the water melted in the snow melting room C is made to flow from the drain port 3 provided in the hot water snow melting room shielding plate 8, and hot water is discharged to the upper part of the hot water snow melting room M. A pipe 16 is provided, and the other end of the hot water discharge pipe 16 is connected to a discharge pump 17 provided at the bottom of the hot water snow melting chamber M,
High-temperature snowmelt water is pumped up by the discharge pump 17 and jetted out of the hot water discharge pipe 16, and the hot water spouted from the hot water discharge pipe 16 dissolves the snow put into the hot water snowmelt chamber M. The bottom of the hot water snowmelt chamber M is communicated with the drainage storage chamber H further below the filter 54 through the filter 54, and finally the snowmelt water reaches the drainage storage chamber H from the filter 54 and enters the drainage storage chamber H. The water is discharged by the provided drain pump 22 and discharged from the drain pipe 21 to a manhole or the like.

A burner cover 18 is disposed and covered on the upper surface of the burner chamber E, and a burner control panel 12 is mounted on the back of the burner cover 18.
A burner control box 13 is fixed to an inner surface of the burner control box 2. A snowmelt tank lid 49 is disposed on the upper surfaces of the snowmelt chamber C and the warm water snowmelt chamber M, and the snowmelt tank lid 49 pivotally supports one side,
A pressure cylinder 50 is provided between the snow melting tank lid 49 and the snow melting tank 2.
The snow melting tank lid 49 can be opened and closed by mechanical force. At the lower end of the snow melting chamber C, there is formed a mud chamber D separated by a mud separating plate 23, and the upper surface of the mud chamber D is covered with a mud chamber lid 4. Also, between the height of the drain port 3 and the lower surface of the furnace body A,
The lower surface of the snow melting tube A is configured so as to be constantly immersed in the inside of the snow melting water pool W, and the burner B does not leak hot air from below.

The snow-melting cylinder A is formed in a substantially pentagonal shape when viewed from the front, and a linear opening is provided at the ridge portion 5 from which hot air of the burner B is discharged. When the thrown snow closes on the ridgeline portion 5 at the top, only the portion is first melted by the direct hot air from this portion, so that the snow mass in the snow melting tank C is divided into two parts. This has the effect of increasing the speed of falling along the front and rear side walls of the snow melting cylinder A. A cooling water chamber F partitioned by the cooling chamber shielding plate 6 is formed at the end of the snow melting cylinder A. Even when the part is burned by the high heat flame from the combustion part 1, no deformation or perforation occurs. It is configured as follows.

The chimney 2 of the present invention is installed in the cooling water chamber F.
7 are arranged. That is, FIG. 3, FIG. 4, FIG. 5, FIG.
As shown in FIG. 7, a chimney case 26 having a U-shape in plan view is vertically arranged at the center in the left and right direction of the cooling water chamber F, and a chimney base 30 and a chimney fixed on the chimney base 30 in the chimney case 26. 2
8 and 28 and a spring 29 are housed therein, and the chimney 28 is constituted by a pipe.
It is shaped like a box that just fits in the vertical slide. However, the shapes of the chimney case 26, the chimney 28, and the chimney stand 30 are not limited. A communication hole is opened on the upper surface of the chimney base 30 to communicate with the lower ends of the chimneys 28, 28, and an opening 30a is provided on the side of the chimney base 30 on the side of the snow melting cylinder A,
An exhaust outlet window 31 is formed in the middle of the snow melting cylinder A on the side of the cooling water chamber F in the vertical direction. However, the chimney case 26 can be disposed at any position where the chimney case 26 can communicate around the snow melting cylinder A.

With such a configuration, the chimney 2
When the snowmelt tank lid 49 is closed, the upper end of the chimney 28 is pressed by the snowmelt tank lid 49 and stored in the chimney case 26 as shown in FIGS. And
When the snowmelt tank lid 49 is opened, as shown in FIGS. 4 and 6, it is raised by the force of the spring 29 provided below the chimney 27,
The opening 30a of the chimney base 30 is raised to a position that coincides with the exhaust outlet window 31, and the snow melting cylinder A and the chimney 28 communicate with each other.

When a large amount of snow is thrown into the snow melting chamber C at one time in this manner, the snow falls on the snow melting cylinder A without any gap, and the combustion exhaust gas from the burner B is not discharged from the snow melting chamber C.
Exhaust gas is released through the chimney 28 through the exhaust port window 31 and the exhaust outlet window 31, and the fire of the burner B does not go out. Since the chimney case 26 is housed in the cooling water chamber F, the chimney case 26 is cooled, and no distortion or the like occurs.

[0013]

According to the present invention, the following effects can be obtained. A chimney case 26 is vertically arranged on the side of the snow melting cylinder A and communicates therewith.
The chimney 27 is housed so as to be able to move up and down, and the chimney 27 communicates with the snow melting cylinder A, so that even if a large amount of snow is thrown in at one time, the flue gas from the burner B can be discharged from the chimney. The problem that the fire of the burner B was extinguished due to the blockage was eliminated. Then, when the lid is closed, it can be stored in the snow melting chamber C and does not get in the way. When the lid is opened, it protrudes upward and is not buried in snow.
