The intake case 22 is usually housed in the burner chamber 4 together with the lid 1, but when used, The air required for combustion at the riser and the burner 18 is taken in by an airflow indicated by an arrow in FIG. 1 through the intake port 22a.

In the snow melting chamber 5, a furnace body 8 of the present invention and a pump arrangement portion 6 are provided, and an opening 25a is provided in one side plate 25b of the side of the furnace body 25 of the furnace body 8. The discharge port 18a of the burner 18 is inserted and supported in the opening 25a. The furnace body 8 is supported with its lower surface suspended by supports 16 and 17, and the bottom plate of the snow melting chamber 5 in which the supports 16 and 17 are fixed on the upper surface is a pump provided one step lower than the furnace body 8. It is inclined so as to descend toward the arrangement part 6, so that the snow-melting water easily flows into the pump arrangement part 6 side.

A discharge port 12 is provided in the frame 2 on the side of the pump disposition portion 6 so as to discharge the water in communication with a drain groove, a manhole 26 and the like. Further, an automatic submersible pump 11 is disposed in the pump disposition section 6, and the automatic submersible pump 11 is activated when water accumulates in a predetermined amount in the pump disposition section 6, and the water in the pump disposition section 6 is discharged to the water level. Is controlled to stop automatically when it falls to the set height.
The automatic submersible pump 11 sucks in from the lower part and discharges it from the upper part. The shower pipe 13 of the present invention is connected to the discharge pipe 11a. The shower pipe 13 has one main pipe 13 having one end connected to the discharge pipe 11a and the other end extending in the front-rear direction above the pump disposing portion 6.
and a plurality of branch pipes 13a extending perpendicularly from the main pipe 13c to the burner chamber 4 side. The water discharged from the 13a prevents overheating of the furnace body 8 and snow melting described later. It does the processing.

Next, the structure of the furnace body 8 of the present invention will be described with reference to FIGS. As shown in FIG.
Is composed of a furnace body 25 and a chimney 14 fixed on the upper surface thereof. As shown in FIG. 2, the furnace body 25 has a substantially triangular shape, strictly pentagonal shape in a side view, and has a hollow interior. The left side surface is formed by a side plate 25b into which a burner discharge port 18a is inserted. The surface is closed by the side plate 25c. The shape of the furnace body 25 is not limited to a polygon, but may be a cylindrical shape.

A ridge 25 at the top of the furnace body 25 at the front and rear center
is provided with a plurality of exhaust ports 25d. On the exhaust ports 25d, chimneys 14, 14,... formed by bending a short pipe into a "-" shape in side view are fixed in the front-rear direction. Has been established. A substantially center of the chimney 14 communicates with the inside of the furnace body 25 through an opening provided below the bent portion 14b, and front and rear ends of the chimney 14 are opened into the snow melting chamber 5 as discharge ports 14a, and burners 18 are provided. Hot air from the furnace body 2
5. It is configured to be fed into the snow melting chamber 5 through the chimney 14.

In such a configuration, when snow is removed from the snow melting chamber 5, a snow sensor 27 shown in FIG. 3 and disposed below the second short branch pipe 13a from the lid 1 side is provided.
However, it senses the weight of the snow and transmits a signal to the control box to ignite the burner 18 and emit a flame. The flame heats the furnace body 25 and generates hot air indicated by arrows in FIG. The hot air becomes an updraft and becomes the chimney 14.
Then, the chimney 14 is discharged into the snow melting chamber 5 from the discharge port 14a while heating. As a result, the injected snow is melted by the contact heat and the radiant heat of the furnace body 25 and the chimney 14, which have become hot, and the snow that has not melted and falls to the bottom of the snow melting chamber 5 is also heated by the hot air discharged from the chimney 14. It will melt snow.

Even if the snow-removed snow is packed in the upper part of the snow-melting chamber 5 without any gap, it is always ventilated from the chimney 14,
Since the burner 18 does not disappear due to incomplete combustion due to lack of air, and even if incomplete combustion products 20 including soot and oil are generated during the combustion, they are attached to the furnace body main body 25 and the inner wall of the chimney 14. It is not discharged to the snow melting chamber 5 and drained to the manhole 26 or the like together with the snow melting water.

Furthermore, by providing the chimney 14 with the bent portion 14b as in the present invention, the incomplete combustion which is directly attached to the inner wall of the bent portion 14b or brought from the inner wall of the furnace body 25 to the inner wall of the bent portion 14b. The object 20 can also be reliably rendered harmless due to the high-temperature and high-pressure hot air that collides with the bent portion 14b at high speed. That is, the incompletely combusted products 20 are completely burned, and can be discharged as harmless gases such as water and carbon dioxide. The harmless exhaust gas is also supplied to the inlet 5a of the snow melting chamber 5 through the chimney 14.
Therefore, it is possible to completely prevent the exhaust gas from being exhausted to the manhole 26 and harming the environment.

Next, the structure of the shower pipe 13 of the present invention will be described with reference to FIGS. 1, 3, 5, and 6. FIG. A main pipe 13c is provided horizontally above and below the automatic submersible pump 11 in the front-rear direction, supported by a pipe support frame 28 fixed to the frame 2, and a large number of pipes extend from the main pipe 13c toward the burner chamber 4 side. The branch pipes 13a are extended, and the tip of the branch pipe 13a is placed on a pipe support frame 19 having both ends fixed to the upper part of the frame 2. That is, one main pipe 13c and a number of branch pipes 13a that are firmly supported cover the inlet 5a of the snow melting chamber 5, and the branch pipe 1
3a has a structure having a function as a kind of protection net. Also, a large number of ejection holes 13b are opened on the upper surface of the branch pipe 13a, and the branch pipe 13a is pivotally supported on a side surface of the main pipe 13c so as to be fixed at a specific angle. Water can be discharged upward,
In this case, the water discharge angle can be freely changed.

In such a configuration, the snow-melted water heated in the snow-melting chamber 5 and pumped by the automatic submersible pump 11 is discharged upward from the jet holes 13b, and the snow-removed snow is injected into the branch pipe 13a. Then, the high-speed high-temperature water separates the snow into small chunks, immediately drops onto the high-temperature furnace body 8 from the gap between the branch pipes 13a without clogging, and easily melts the snow. Therefore, it is possible to save the labor of manually digging and dropping a clogged snow mass by hand, thereby improving the snow melting efficiency and greatly reducing the burden on the operator.

Further, since the snow does not block the inlet 5a for a long time, the upper part of the inlet 5a is always open, and the intake of outside air and the discharge of exhaust gas are performed very efficiently. Can be prevented, and the generation itself of the incompletely combusted products 20 can be greatly reduced.

Since the water discharge angle of each branch pipe 13a can be freely adjusted, water discharge conditions can be set in consideration of the processing environment. For example, when the wind is strong, the water discharge angle is changed so that the water discharge direction is directed toward the lid 1 so that water blown by the wind does not fall on the worker. The water discharged from the hole 13b can be concentrated on a specific location of the thrown snow, so that the snow chunk can be easily divided. The main pipe 13 of the branch pipe 13a
The method of connection to c is not particularly limited as long as it is rotatable and the water discharge angle can be fixed at a specific angle.

As described above, the present invention has the following advantages. That is, as in claim 1,
The discharge port of the burner is inserted into the snow melting chamber, the discharge port is covered with a furnace body, and a chimney communicating with the snow melting chamber is provided at the upper part of the furnace body, and hot air from the burner can collide with the chimney. Because of the bent portion, even if incomplete combustion occurs, it adheres to the inner wall of the furnace body or chimney or is completely decomposed in the chimney, so it mixes with snowmelt water and flows out from manholes etc. Since the exhaust gas is discharged to the upper part of the snow melting chamber through the chimney, it is not discharged to a manhole or the like.

The discharge port of the burner is inserted into the snow melting chamber, the discharge port is covered with a furnace body, and a plurality of shower pipes capable of discharging water upward are provided at the input port of the snow melting chamber. As a result, snow chunks are quickly separated and snow melting efficiency is greatly improved, and clogging due to snow is eliminated, so that ventilation in the snow melting room is good and incomplete combustion of the burner itself can be prevented. .

According to the third aspect of the present invention, the water discharge angle of the shower pipe can be freely changed, so that the water discharge angle can be set to an appropriate water discharge angle according to the natural environment, and the snow melting efficiency and the working environment can be improved. You can do it.
