Description

[Detailed description of the invention] A. Purpose of the invention (a) Industrial application field This invention is intended to provide a snow melting device having a novel configuration.

B. Conventional technology and its problems Conventional snow melting is far from practical use, and snow removal is mainly done using shovels or bulldozers, and snow melting is almost impossible. If you stir the snow while soaking it in jab and sprinkle it with suction power, the snowpack will not dissolve easily.
Since the pot is always full of water, the temperature of the pot can hardly be maintained, making it impossible to expect any effectiveness.

B. Structure of the invention A. Means for solving the problem This application attempts to solve the above-mentioned problem with the following structure. That is, in the present invention, a burner 3 is attached to a combustion chamber 2 formed by connecting a side wall 2B to the upper surface of a bottom plate 2A. An air chamber 4A is provided on the outer periphery of the cylindrical snow melting pot 4 placed on the upper surface of the combustion chamber 2, and an outer cylinder 5 is disposed therein, and the air chamber 4A and the combustion chamber 2 have a communication port 4B. A bottom net 6 is stretched horizontally below the snow melting pot 4, and an overflow pipe 7 is provided at a position slightly above the bottom net 6 on the side wall of the snow melting pot 4. A vertical shaft 9 is rotatably provided at the center of the axis, and a suitable number of stirring plates 10 are horizontally attached to the vertical shaft 9 with vertical directions. A heat exchange pipe 13 piped inside the combustion chamber 2 is connected to the pressure pipe 12B, and a hot water supply pipe 14 reaching the upper end of the snow melting pot 4 is connected to the heat exchange pipe 13, and further, A heat exchange/hot water supply pipe 15 connected to this pipe 14 is tightly wound around the outer peripheral surface of the snow melting pot 4, and a high pressure nozzle 16 protruding into the snow melting pot is installed at a predetermined location of this pipe 15. This is the snow melting equipment installed.

B. Example 1 of the invention is the snow melting device of the invention. 2 is a combustion chamber formed by connecting a side wall 2B to the upper surface of a bottom plate 2A, and a burner 3 is attached to this combustion chamber 2 via a partition wall 2C. Reference numeral 4 denotes a cylindrical snow melting pot placed on the upper surface of the combustion chamber 2, and an air chamber 4A is provided on the outer periphery of the snow melting pot 4, and an outer cylinder 5 is disposed therein. In this case, this air chamber 4A and the combustion chamber 2 are connected to the communication port 4.
It is communicated via B. 6 is a bottom net stretched horizontally below the snow melting pot 4, and 7 is an overflow pipe attached to the side wall of the snow melting pot 4 slightly above the bottom net 6 and directed outward. Reference numeral 8 denotes a bearing and chain case which is stretched over the top surface of the snow melting pot 4 leaving a snow throwing opening 8A, and a vertical shaft 9 is provided between the bearing and chain case and the bottom net 6 so as to be freely rotatable. A suitable number of stirring plates 10 are attached to the vertical shaft 9 in a horizontal state with vertical directions. Reference numeral 11 denotes a motor for rotating the stirring plate, which is attached to the outer cylinder 5 and is connected to the vertical shaft 9.
are connected to each other by a chain 21. Reference numeral 12 denotes a pressure pump installed on the side of the outer cylinder 5, and a suction pipe 12A drawn out from this pump is pulled in to be located below the snow melting pot 4, that is, below the bottom net 6. A pressurizing pipe 12B drawn out from the pump 12 is piped into the combustion chamber 2, and at the tip of the pressurizing pipe 12B there is a heat exchanger connected to the burner 3 in the form of a conical spiral. A pipe 13 is connected to the heat exchange pipe 13, and a hot water supply pipe 14 that reaches the upper end of the snow melting pot 4 using the air chamber 4A is connected to the heat exchange pipe 13. Reference numeral 15 denotes a heat exchange/hot water supply pipe connected to this pipe 14, which is tightly wound around the outer peripheral surface of the snow melting pot 4, and its tip 15A is sealed. A high-pressure nozzle 16 is attached to a predetermined location, and furthermore, this nozzle 16 is made to protrude into the snow melting pot 4.
Reference numeral 17 denotes a muffler provided above the air chamber 4A, and the air chamber communicates with the outside air through this muffler. 18 is a drain pipe for the snow melting pot,
Reference numeral 19 indicates drain pipes for heat exchange pipes.

C operation Explain along with the effects.

C Effect of the invention In this invention, water is injected up to the overflow pipe position, that is, the water level, the water is sent to the pipe 13 in the combustion chamber by the pressurizing pump, and the water is sent to the pipe 14 while maintaining the water temperature at 90°C by the burner 3. A mist is sprayed under pressure from nozzles 16 at several locations. The snowpack thrown in at this time is moved to various positions by a rotating stirring plate. As a result, warm water is evenly sprayed onto the snowpack, turning it into snowmelt water. Snowmelt water is drained through the overflow pipe. In this case, the amount of water required for circulation is pressurized and heated by the pump, and is injected directly only onto the snowpack, so that a reliable effect can be achieved and the snow melting action can be continued. Since the melted snow does not collect water above the drain, pipes are arranged inside the pot.
Pressurized hot water is sprayed directly onto the snowpack from several nozzles installed, and the rotating blades move the snowpack, so the hot water is sprayed evenly and melts the snow, and only the water below the drain is circulated. It is used as a fuel and heats only the pipe in the combustion chamber, so
Can maintain high temperature at all times. Note that 20 is a fuel tank.
