Summary: Structure of the Invention [Means for Solving Problems] The present invention has a main body surface that divides the inner space into two chambers, an upper snow throwing chamber and a lower heating chamber, by a middle bottom plate, and a lower heating chamber. It consists of an oil burner that blows flame or hot air into the heating chamber. The device is installed inside the main body box at an angle so that the melt water that accumulates in the valley will actively flow along the length of the valley, and the lower heating chamber has an exhaust chimney, and the upper snow injection chamber has an exhaust chimney. Connecting drainage channels. The main topic is snow melting equipment.

[For production]

The inner sole plate is heated by the flame or hot air blown into the heating chamber by a petroleum (heavy oil, light oil, additional oil, etc.) burner and becomes a hot plate. When snow is thrown into the upper snow-throwing chamber, the snow is melted by the heat of the heated inner sole.

Melt water actively and rapidly flows along each bent valley on the upper surface of the midsole plate in the direction of valley inclination, and is discharged from the drainage channel to the outside of the device.

The middle sole plate has a sawtooth cross section and is greatly curved into a waveform to increase the surface area, so the bottom side has a large area to receive heat from the flame or hot air blown into the heating chamber, allowing efficient heating with less heat loss. receive. Further, on the upper surface side, the contact area with the snow thrown into the snow throwing chamber is large, and the thrown snow is efficiently and quickly melted. As a result, the melt water actively and quickly flows away in the direction of the slope of the valley along each bent valley on the upper surface of the mid-sole board and does not accumulate, so the heat of the mid-sole board is wasted as melt water that no longer needs to be heated. There is less heat loss.

Therefore, it has a simple and compact device configuration, and also has good thermal economy.
It is capable of efficiently and continuously melting snow.

The main body surface 1 of the device is installed in a recessed hole A with its lower part supported by a concrete frame-shaped pedestal with the snow inlet 2 surface facing the ground G and the road surface. 4a, 4a are opening/closing hinge parts of the lid plates 4, 4, and 4b, 4b are handle parts for opening/closing the lid plates.

Reference numeral 5 denotes a mid-sole plate disposed within the above-mentioned device main body surface l, and this mid-sole plate is greatly bent to have a sawtooth cross section as shown in Figures 3 and 6 to increase its surface area, and will be described later. In order to cause the melted snow accumulated in each bent valley part 5a of the middle sole plate to actively flow along the length of the valley part,
It is arranged at a slight angle downward to the left in the figure. The inside of the device main body 1 is divided into a snow charging chamber 6 on the upper side and a heating chamber 7 on the lower side with the middle sole plate 5 as a boundary. Reference numeral 8 denotes a fin-shaped auxiliary plate welded substantially perpendicularly along the length to each bent ridge 5b of the mid-sole plate, and the upper part of each auxiliary plate 8 is made to substantially coincide with the opening surface of the snow inlet 2.

Reference numeral 14 denotes a chimney that can be freely attached to and detached from the exhaust pipe port 9b of the exhaust gas collection chamber 9.

When the device is not in use, the chimney 14 is removed and the snow charging chamber cover plates 4, 4 and the burner chamber cover plate 12 are closed as shown in Figure 5. Since the upper surface of 12 becomes the ground G and the road surface, it can be used as a road surface, a parking scene, etc.

When the apparatus is used, the cover plates 4, 4, and 12 are opened and raised, and they are connected to each other by a connecting rod 13 to maintain an obliquely raised position. These three raised lid plates 4-4 and 12
The snow input hopper section is configured by this. Install chimney 14.

The burner 11 is ignited. Since the cover plate 12 is held open in the burner chamber, sufficient outside air can enter the burner chamber, and air can be supplied to the burner 11 without any problem. By igniting the burner 11, flame is blown into the heating chamber 7 from the nozzle 11a, and the inner sole plate 5 is heated and turned into a hot plate.

Since the middle sole plate 5 is greatly bent to have a sawtooth cross section, the heat receiving area from the flame blown into the heating chamber 7 is large.
Efficient heating of the inner sole plate is achieved with little heat loss. Combustion gas in the heating chamber 7 enters the exhaust collection chamber 9 through triangular through holes 9a formed in the wall portion of the exhaust collection chamber corresponding to the inside of each bent ridge 5b of the middle bottom plate, and exits from the chimney 14 to the outside world.

Snow is thrown into the snow throwing chamber 6. Then, the thrown snow is melted by the heat of the middle sole plate 5, which is turned into a hot plate. Middle sole plate 5
As mentioned above, since the cross section is greatly bent into a sawtooth shape, the contact area with the thrown snow is large, and the thrown snow is efficiently melted. Melt water flows through each bent valley 5 of the middle sole plate 5.
The water flows actively and rapidly in the trough inclination direction along a, and flows into the melt water collection chamber 10 from each inverted triangular through hole 10a formed in the wall surface portion of the melt water collection chamber corresponding to each valley.

The water flows through the drain pipe 15 to an underground drain pipe or drainage ditch (not shown). There is little heat loss in which the heat of each bent valley part 5a of the plate 5 of the middle sole plate 5 is wasted away by the melted water.

In this way, by throwing snow one after another into the snow throwing/inlet chamber 6, snow melting can be carried out efficiently and continuously with a simple and compact device configuration and good thermoeconomics.

Furthermore, by adding a fin-like auxiliary plate 8 to each bent ridge 5b of the mid-sole plate as in the illustrated example device, this auxiliary plate 8 is also made into a hot plate, and can penetrate into the snow thrown into the snow throwing chamber 6, respectively. Since it comes into contact with the snow, snow melting can be performed more efficiently.

By making the snow input chamber 6 of the underground type with the opening surface between the ground G and the road surface as in the illustrated example device, the snow shoveled by a snow boat or shovel can be moved as it is by pushing the ground G as shown by the arrow in FIG. The snow can be dropped into the snow throwing chamber 6 from the part without a cover plate, as shown in the figure, and the snow can be thrown in efficiently.
