Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a snow melting device, and more specifically to a device for melting snow removed from roofs, snow removed from roads and gardens, etc.

(Prior technology) A device for melting snow by putting the removed snow into a container containing hot water was developed in the 47th year of the Special Publication.
There are publications such as Publication No. 30331 and Japanese Utility Model Application Publication No. 1962-1962.

(Problem to be solved by the invention) In the former of the above-mentioned conventional techniques, the main body is connected to the hot water tank provided at the upper part of the main body, and the front and back of the lower part,
Heating chambers are installed vertically and horizontally, and the space divided by these heating chambers is used as a combustion chamber, but the communication hole connecting each heating chamber or hot water tank allows snow to mix with snow and be thrown into the hot water tank. Blocked by sediments such as soil, sand, mud, and pebbles, it becomes impossible for water to flow between the heating chambers, and if the heat source is burning, it will become dry and steam will be generated, creating a dangerous situation. Additionally, there is a problem in that the heating chamber may be destroyed.

In addition, in the latter method, the exhaust port of the snow melting heat source is arranged toward the inner edge of the snow melting tank, so that the exhaust heat directly hits the snow in the snow melting tank and melts the snow. , the bottom of the snow melting tank and an external water storage tank are connected by a passageway, and the water storage tank has one meltwater outlet.
Therefore, if the melting capacity is higher than the drainage capacity, there is a problem in that the melt water enters the heating chamber filled with exhaust heat from the exhaust port.

The present invention was developed in view of the above-mentioned problems of the conventional technology, and its purpose is to reduce the snow melting efficiency even if the container is made smaller, and to improve the heat exchange of the snow melting heat source. The present invention aims to provide a snow melting device that can improve efficiency and reduce manufacturing costs.

(Means for Solving the Problems) In order to achieve the above object, the snow melting device of the present invention has a heat source for snow melting disposed inside a movable container body, and an operating source for the heat source located around the container body. In the snow melting device, the heat source for snow melting is formed in the shape of a flat box, and the water pipe penetrates the box in the vertical direction. The heat source for snow melting is installed floating above the bottom plate of the vessel, the exhaust port of the heat source is formed from the periphery of the vessel toward the inside of the vessel, and the heat source for snow melting is installed on the peripheral wall of the vessel. An overflow drain port is provided below the heat source exhaust port, and an auxiliary exhaust/drain port is provided between the overflow drain port and the snow melting heat source exhaust port.

(Function) According to the above means, the snow thrown into the container from the snow input port on the top surface of the container is melted by the heat of the snow melting heat source, and the snow melting water is heated by the heat of the snow melting heat source and turned into hot water. becomes. The snow that is thrown into the vessel from the inlet is melted by the warm water. Moreover, the heat source of the snowmelt water is installed floating above the bottom plate, and the water pipes penetrate the top and bottom, so the hot water undergoes convection and becomes uniform with almost no temperature difference between the top and bottom. Increased water content due to melting snow is drained from the drainage holes on the peripheral wall of the vessel.

Furthermore, since the exhaust port of the heat source for snow melting is directed toward the inside of the vessel, the snow thrown in from the snow input port is not only melted by the hot water, but also by the exhaust heat before that. In addition, if a large amount of snow is put into the snow inlet and it melts all at once, the amount of melted snow water increases all at once, and the water cannot be treated by draining only from the overflow outlet. Drain water from the auxiliary exhaust/drainage port located lower to prevent melted snow water from flowing into the exhaust port.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. 1 is a container body, 2 is a heat source for snow melting, 3 is a snow input port, 4 is an exhaust port, 5 is an overflow drain port,
6 is a water pipe, and 7 is an auxiliary exhaust/drain port.

The container body 1 is formed into a box shape by a flat metal plate, and the front part is curved in an arc to improve sliding on the snow like a sled. Further, a hand lever 8 is attached to the rear of the vessel 1, and wheels 9 for running are provided at the bottom of the vessel 1, so that it can be moved by running even in areas without snow. Further, on the rear side of the vessel body 1, there is a housing section 1 that houses a burner 10 that serves as an operating source for the snow melting heat source 2, a fuel tank 11, a supply pipe 12 that supplies fuel to the burner 10, and the like.
A gauge 14 is provided on the upper surface of the storage portion 13 to visually check the remaining amount in the fuel tank from the outside.

It is more effective to cover the outer surface of the vessel 1 with a heat insulating material to prevent the hot water inside from being degraded by the outside air.

The snow melting heat source 2 installed in the container body 1 is formed into a flat box shape using a flat metal plate, and its interior is separated from the center to the left and right by a flat gate-shaped partition plate 15 and a linear partition plate 15'. A passage meandering in the direction is formed into sections, join together at the tip, and reach the exhaust port 4 formed by raising the tip upward, and the central portion on the opposite side from the exhaust port 4 has the above-mentioned passage. burner 10
The front end of the flat box body is fitted so that the flame and combustion heat generated by the operation of the burner 10 reach the exhaust port 4 of the front end through a divided passage, and heat is radiated from the entire surface of the flat box body. be.

Further, the snow melting heat source 2 has partition plates 15 and 15'.
A water pipe 6 is fixedly positioned in the passage defined by the passageway and penetrates in the vertical direction, so that snowmelt water can be heated efficiently.

Further, the exhaust port 4 of the snow melting heat source 2 is bent toward the center of the snow input port 3, so that the snow thrown into the container body 1 can be melted by the exhaust heat.

Furthermore, an auxiliary exhaust/drainage port 7 is opened on the front surface of the peripheral wall of the container body 1, located between the overflow drain port 5 and the exhaust port 4, and the input port 3 of the container body 1 is blocked by snow. When the condition is reached, a large amount of snow is thrown in and melted all at once, and due to the increase in snowmelt water, drainage from only the overflow drain port 5 is not enough, and the snowmelt water (warm water) increases in the exhaust port 4.
It is designed to prevent the inflow of

Furthermore, the snow melting heat source 2 described above is mounted inside the vessel 1 so as to float above the bottom of the vessel 1, so that the entire circumferential surface of the heat source 2 works efficiently for heat exchange.

In the figure, 16 is a drain valve, 17 is a cover for the drain port 5, and the connection part 17' for a hose etc. is connected to the cover 17.
is provided.

(Effect of the invention) Since the snow melting device of the invention is configured as described above,
The entire circumferential surface of the snow melting heat source effectively acts as a heat exchanger, allowing efficient snow melting. Moreover, as the snowmelt water is heated and rises, the heated hot water is convected through the water pipe, and there is no temperature difference between the top and bottom, making it possible to efficiently melt the snowpack that is thrown in one after another. .

In addition, the water increases due to melting snow, and heated water is drained from the overflow drain, but since the water is heated and heated, rather than the low-temperature water near the bottom of the vessel, as in the conventional case, the water is heated. The hot water generated can also melt snow, ice, etc. on the road. Furthermore, an auxiliary exhaust/drainage port is provided in the body between the exhaust port and the drain port, which is effective against the increase in snowmelt water that cannot be treated by draining only from the overflow drain port. This prevents snowmelt water from flowing into the exhaust port, and even if the snow input port becomes blocked by snow and there is no exhaust outlet, the exhaust from the exhaust port will be auxiliary. It is discharged from the exhaust port, ensuring safety.
