Abstract

PURPOSE:To improve the thermal efficiency so as to enhance the snow melting capacity by mounting, on the bottom part of a snow melting, an air-heating furnace provided with a water reservoir and many blowout holes on the upper part thereof. CONSTITUTION:An air-heating furnace 2, whose circumferential walls except the upper part are constructed with thermal insulating material and having a freely removable upper face plate 3 is mounted on the lower part of a snow melting bath 1, and many air blowout holes 5 whose circumferences are embanked with vertical water-proof dikes 6 are drilled on the upper face plate 3. Then, a water reservoir 4 is installed on the upper surface of the air-heating furnace 2, and the thaw of snow accumulated in the water reservoir 4 is discharged through a exhaust pipe 9, whereby a specified depth of the thaw is maintained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to a snow melting machine for melting snow accumulated on roads, gardens, etc.

[Conventional technology]

Conventional snow melting methods include, for example, Jikoaki! 59-38501
and 61-23064, which melts snow by spraying boiling water on the snow or placing the snow in boiling water;
There is a hot plate method that melts snow by placing snow on a heated iron plate.

[Problem to be solved by the invention]

In the conventional '@snow method described above, the combustion gas (flame or hot air, etc.) in the combustion furnace that heats the hot water and hot plates is not sufficiently exchanged with the hot water and hot plates, and the snow melting machine remains hot. The combustion gases could not be used effectively as they were emitted outside, resulting in extremely poor thermal efficiency. Therefore, unless the amount of combustion in the combustion furnace was increased considerably, the hot water and hot plate would gradually be cooled by the snow, making it difficult for the snow to melt.

An object of the present invention is to utilize combustion gas sufficiently effectively, improve thermal efficiency, and improve snow melting ability (ability per unit combustion amount) in order to solve the conventional problems.

[Means to solve the problem]

The first invention, the snow melting machine, has a hot air stove (2) installed at the bottom of the melting MFj (1), and a large number of blowholes (5...) on the top surface of the hot air stove (2). It is.

The snow melting machine which is the second invention is the snow melting machine in the above-mentioned first invention,
A water tank (4) is formed on the top surface of the hot air stove (2) along with a waterproof embankment (6) for a blowhole (5).

The snow melting machine which is the third invention is the snow melting machine according to the first invention,
The top plate (3) of the hot air stove (2) is detachably attached to the main body of the hot air stove (2).

[Effect]

When the snow to be melted is put into the snow melting tank (1), this snow layer is placed in the lower part 11 of the snow layer! In the lower part of the snow tank), the hot air stove (2
) The snow is melted by the hot air that blows out from the blowhole (5...). At this time, since the density of the snow layer is coarse, the hot air passes through the snow layer and is discharged to the upper part of the outside of the snow layer (the upper part of the outside of the snow melting tank).

To explain in more detail, the upper snow layer of the snow that is successively put into the snow melting tank (1) comes into contact with the hot air passing through the snow layer and is gently heated, resulting in a small amount of primary snow melting.

In addition, the lower snow layer that has settled from the upper layer is the blowhole (5...
・) The snow is heated strongly by the hot air emitted from the snow, and a large amount of snow melts secondary. These snowmelt water is stored in a water tank (4
), it becomes hot water and promotes the above-mentioned snow melting action.

That is, the remaining lower snow layer after the second snow melting enters the water storage tank (4) and is bathed in hot water, resulting in a complete third snow melt without remaining snow. The hot air passing through the snow layer undergoes sufficient heat exchange with the snow layer (is effectively used), and is discharged upward outside the snow layer as cold air.

The rough density (space) of the snow layer truly acts as a chimney and heat exchanger for hot air.

The snowmelt water accumulated in the water storage tank (4) cools the top surface of the hot stove (2) and prevents the soil plate (3) from being thermally deformed. When the top plate (3) is deformed, it is sufficient to remove the top plate (3) from the main body of the hot air stove (2) and replace only this top plate (3) with a new one.

〔Example〕

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

Reference numeral 1 denotes a snow melting tank consisting of a rectangular frame body, and a hot air stove 2, which is also rectangular, is installed at the bottom of the tank. The hot air stove 2 has an outer circumferential wall other than the upper surface made of a heat insulating material, and also consists of an upper plate 3 whose upper surface is shelved at an appropriate lower level than the tops 1 & 2a of the outer circumferential wall, and whose upper side is formed into a water storage tank 4. It is. This top plate 3
The outer peripheral wall (
It is removably attached to the hot air stove (2 main body).

Reference numerals 5 and 5 designate a number of blowholes formed in the upper surface plate 3 of the hot air stove 2, and a waterproof embankment 6 made of a cylindrical body having an appropriate height is erected around the periphery of the blowholes. This waterproof embankment 6 is for preventing melted snow water and snowflakes accumulated in the water tank 4 from entering the hot blast stove 2 through the blowhole 5, and has a blowhole 7 formed at the upper part of the circumferential side thereof. At the same time, an umbrella body 8 is provided over its head. The umbrella body 8 prevents snowflakes from entering the hot blast furnace 2 through the blast opening 5, and also prevents hot air blowing out from the blast opening 5 from entering the blast window 7.
This is to spread the hot air more evenly in the horizontal direction and to evenly shower the lower snow layer with the hot air for snow melting (secondary).

9 is a drain pipe attached to the outer peripheral wall of the water storage layer 4;
The snowmelt water accumulated therein is located at an appropriate height so as to come out from the drain pipe 9 without entering the hot blast stove 2 through the blast window 7 of the waterproof embankment 6 while maintaining a predetermined depth.

In addition, the code lO in the figure is a combustion machine that feeds hot air into the hot air stove 2, 11 is its kerosene tank, 12 is a trolley, ]3 is its handle, 14...+, 1 is a mounting hole on the top plate 3. , S indicates a snow layer, W indicates snowmelt water, and H indicates hot air.

[Effects of the Invention] Since the present invention has the configuration as described above, it exhibits the following excellent effects.

■ When the hot air blowing out from the hot air stove (2) passes through the snow layer, it sufficiently exchanges heat with the snow layer (becomes cold air) and is used effectively. Therefore, thermal efficiency is good and snow melting ability is increased. In particular, since the snow melting action is performed in a stepwise manner, from the first stage to the second stage, the snow can be melted easily, effectively, and quickly.

■ The snowmelt water accumulated in the water storage tank (4) turns into hot water and promotes the snowmelting action described above (tertiary snowmelting).
2) Cool the top surface of the top plate (3) to prevent thermal deformation of the top plate (3).

■ The top plate (3), which suffers the most thermal deformation and damage, can be replaced separately from the main body of the hot air stove (2).
