DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for heating a large amount of snow contained in a snow melting chamber by heating a combustion hot air and exchanging heat with the combustion hot air. The present invention relates to a method and an apparatus for melting snow in a short time by spraying water to discharge hot water.

Prior to the filing of the present application, it is known and described in, for example, Japanese Patent Publication No. 52-38653, the contents of which are described with reference to FIG.

That is, the hot water storage tank 2 is provided at the center, and the hot water storage tanks 2 are provided on both sides thereof.

The other end of the water spray pipe 11 arranged above the snow melting chamber 7 is connected to a hot water pump.
It is configured to be inserted into the hot water feeder 2 via 12.

[Problems to be Solved by the Invention] In the conventional snow melting apparatus of this type, since a large amount of dust and the like is contained in the snow collected by snow removal, the molten snow is scattered during the snow melting operation. When water is sprinkled on a large amount of snow by a hot water pipe, a large number of hot water holes drilled in the hot water pipe cause clogging during long use due to the dust, and a predetermined amount of molten snow Cannot be sprinkled on the snow, and as a result, there is a problem that the snow melting ability is remarkably reduced.

According to the present invention, the snowmelt water in the water collection chamber pumped up by the rotating body is sprinkled on the snow contained in the snowmelt chamber along the running water guide, and at the same time, the flame is directed from the combustion chamber toward the snowmelt chamber from below. Even if the snow contains a lot of garbage, the clogging phenomenon and fluctuations in the amount of water spraying that occur in conventional snow melting equipment are eliminated, and the snow melts quickly, even if the snow contains a lot of dust. It is an object of the present invention to provide a snow melting method and an apparatus therefor that aim to improve the efficiency of snow melting.

[Means for Solving the Problems] To achieve the above object, a basic snow melting method according to the present invention is to melt snow melt water in a water collecting chamber pumped up by a rotating body along a running water guide. Water was sprayed on the snow housed in the snow room, and at the same time, from the bottom, the combustion hot air blazing from the combustion chamber toward the snow melting room was immersed in the snow and melted, and used to carry out the above-mentioned snow melting method. The snow melting device is divided into a pumping part and a melting part, with the upper part being opened and the bottom part having a water collecting chamber. The melting part is divided into a snow melting chamber and a combustion chamber facing a burner. In the pumping section, the lower opening part faces the water surface of the water collecting chamber, a diffuser is provided at the upper edge, and a flowing water guide body that is curved upward toward the snow melting chamber is provided. At the same time, the lower part of the running water guide is immersed in It consists of a rotating body that rotatably holds a rotating body that pumps water and discharges water toward the inner surface of the running water guide.Other snow melting devices have a top open and a bottom with a water collection chamber. Is divided into a pumping section and a melting section, a snow melting chamber and a burner are provided in the melting section, and a combustion chamber in which one side communicates with the pumping section via a hot air inflow passage is sequentially arranged in a three-dimensional manner. In the pumping part, the lower opening part faces the water surface of the water collecting chamber, a diffuser is provided at the upper end edge, and a running water guide body which is curved upward toward the snow melting chamber is provided. A hot air intake port is opened on both sides on the inside of the body, and a rotating body that rotatably stores a rotating body that lowers into the water of the water collecting chamber and pumps up the snowmelt water and discharges it to the inside of the running water guide with the burning hot air. It is configured.

[Operation] Now, a large amount of snow containing dust and the like is stored in the snow melting chamber, and the fuel and the combustion air are sent to the burner to start the combustion. To store a certain amount of snowmelt. Next, the rotating body whose lower part is immersed in the water of the collecting chamber is rotated in the direction of the arrow. Then, the snowmelt water stored in the water collection chamber is pumped up by the rotating body and released toward the inner surface of the running water guide, and the released snowmelt water vigorously flows along the inner surface of the running water guide. ,
Water is continuously sprayed on the snow while being diffused over a wide area by the diffuser provided at the upper edge. On the other hand, the combustion hot air generated by the operation of the burner blows toward the snow melting chamber from the combustion chamber and is poured on the lower surface of the snow contained in the snow melting chamber. Therefore, a large amount of snow contained in the snow-melting chamber is subjected to a melting action of a large amount of snow-melting water continuously sprinkled from the upper surface and a melting action by a heating action of the burning hot air blowing from the lower face. Even if it is a large amount of snow that contains a lot of dust, it can efficiently diffuse a large amount of snow water onto the snow without causing the clogging phenomenon of the diffused water spray seen in conventional snow melting equipment. The molten water is quickly melted, and the dissolved water is dropped into the collecting chamber through the combustion chamber. Promotion can be aimed at.

Also, during the snow melting operation, a part of the combustion hot air generated in the combustion chamber is circulated in the pumping unit via the hot air inflow path, so the combustion hot air is generated by the suction action generated by the rotation of the rotating body. After being sucked into the rotating body from the hot air intake ports on both sides, it is discharged toward the inner surface of the running water guide while being mixed with the pumped snowmelt water, so the temperature of the snowmelt water is further raised, and the snowmelt efficiency is promoted. This can be achieved even more.
