Description

[Detailed description of the invention] B. Purpose of the invention [Industrial application field] The present invention relates to a snow melting device (snow metal).

[Conventional technology]

If snow removed from roads, around buildings, parking lots, etc. is piled up on the sides of the road, the accumulated snow will greatly reduce the width of the road and the area of the parking lot. Transportation and dumping using dump trucks, etc. will incur labor costs and
Transportation costs are high.

The above problems can be solved by actively melting the removed snow on the spot using heat and causing it to flow away as water. Therefore, various snow melting devices have been known that use heat to melt removed snow or accumulated snow. For example, there are the following.

Publication No. 23429, etc. [Problems to be Solved by the Invention] However, various conventional snow melting devices, such as vehicle-type devices, are generally quite large and have complicated device configurations.
In addition to requiring high equipment costs, the snow melting efficiency was not high and the running costs were also quite high.

Therefore, it can be easily owned by each household, inn/hotel or other business establishment, town, etc.
It is desired to develop a simple snow melting device that has a compact configuration, low equipment costs, high snow melting efficiency, and low running costs.

The present invention meets this need.

B. Structure of the Invention [Means for Solving Problems] The present invention comprises a device main body box in which the inner space is divided into two chambers, an upper snow throwing chamber and a lower heating chamber, by a middle bottom plate;
It consists of an oil burner that blows flame or hot air into the heating chamber on the lower side, and the middle bottom plate has a sawtooth cross section or a wavy shape to increase the surface area, and the middle bottom plate is The device is installed inside the main body box at an angle so that the melt water that accumulates in each bent valley will actively flow along the length of the valley, with an exhaust chimney in the heating chamber on the lower side and a snow inlet on the upper side. The main feature is a snow melting device with a melt water drainage channel connected to the room.

[Effect]

The inner sole plate is heated by flame or hot air blown into the heating chamber by a petroleum (heavy oil, light oil, kerosene, 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. The melt water actively and rapidly flows in the direction of slope of the valley along each curved valley on the upper surface side of the midsole plate, and is discharged from the drainage channel to the outside of the device.

The middle bottom has a sawtooth or wavy cross section and is greatly bent to increase the surface area, so the bottom side has a large heat receiving area from the flame or hot air blown into the heating chamber, resulting in efficient heating with little 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. The melt water actively flows away in the slope direction of the valley along each bent valley on the upper surface of the mid-sole plate and does not accumulate, so the heat of the mid-sole board is wasted away by the melt water that no longer needs to be heated. There is less heat loss.

Therefore, the snow melting process can be carried out efficiently and continuously with a simple and compact device configuration and with good thermal economy.

Reference numeral 12 designates an opening/closing lid plate that covers the opening surface of the recessed hole of the oil burner chamber, and includes a hinge portion 12a.
It is opened and closed mainly. 12b is a handle for opening and closing the lid plate. 14 is the exhaust pipe port 9b of the exhaust collection chamber 9
It is a chimney that can be attached and detached freely.

When the apparatus 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 the fifth figure. Closed lid plate 4, 4,
Since the upper surface of 12 is substantially flush with the ground G, it can be used as a road surface, a parking scene, etc.

When the apparatus is used, the cover plates 4, 4, 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 upright cover plates 4, 4, and 12 constitute a snow charging hopper section. Install chimney 14.

The burner 11 is ignited. Since the lid 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. Nozzle 1 is ignited by ignition of burner 11.
Flame is blown into the heating chamber 7 from 1a, and the inner sole plate 5 is heated and turned into a hot plate. Since the mid-sole plate 5 is greatly bent to have a sawtooth cross-sectional shape, the heat receiving area by the flame blown into the heating chamber 7 is large, and the mid-sole plate is efficiently heated with little heat loss. Combustion gas in the heating chamber 7 enters the exhaust collection chamber 9 through the triangular through holes 9a formed in the exhaust collection chamber wall portion corresponding to the inside of each bent ridge 5b of the middle bottom plate, and passes through the chimney 14 to the outside world. Exhausted.

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. As described above, the middle sole plate 5 is greatly bent to have a sawtooth cross section, so that the contact area with the thrown snow is large, and the thrown snow is efficiently melted. The melt water actively and rapidly flows along each bent valley 5a of the middle bottom plate 5 in the valley inclination direction, and each inverted triangular through hole 10a is formed in the wall surface portion of the melt water collecting chamber corresponding to each valley. Flows into the melt water collection chamber 10 from
The water flows through the drain pipe 15 to an underground drain pipe or drainage ditch (not shown). Each bent valley part 5a of the middle sole plate 5
Since the melt water quickly flows away as described above, there is less heat loss in which the heat of the inner sole plate 5 is wasted by the melt water.

In this way, by sequentially charging snow into the snow charging chamber 6, snow melting can be carried out efficiently and continuously with a simple and compact device configuration, and with good thermal economy.

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 opening surface of the snow charging chamber 6 substantially flush with the ground G as shown in the illustrated example device, it is an underground stationary type, so that the snow scraped by a snow boat or shovel can be pushed directly against the ground G as shown in the arrow in FIG. As shown, the snow can be dropped into the snow dumping chamber 6 from the part without the cover plate, and the snow can be dumped efficiently.

Even if rainwater or snowmelt water enters the burner chamber when the device is not in use or in use, the water will flow away through the drain pipe 17 to the drain pipe 15 to the underground drain pipe or drainage gutter. Furthermore, even if rainwater enters the snow charging chamber 6 when the device is not in use, the water will flow away along the same route as the snow melt water outflow route 5a→10a→10→15 described above.

The chimney 14 can be removed from the exhaust pipe port 9b of the exhaust collection chamber 9 and further disassembled into two short pipes, an upper half and a lower half. When the device is not in use, it can be disassembled and the cover plate 4 , 4, 12 together with the connecting rods 13,
It is stored in the burner room or the snow throwing room 6.
