[0007]
The hot water supply device 3 is branched at predetermined intervals from the snow melting pipes 23 arranged on both sides of the upper peripheral edge in the longitudinal direction of the snow melting tank 1, and injects hot water into the blocky snow in the snow melting tank 1. A plurality of spray nozzles 24, a hot water pipe 26 for supplying the snow melting water heated by the boiler 25 to the snow melting pipe 23, and a circulation pipe for returning the snow melting water from the lower part of the snow melting tank 1 to the circulation tank 27. 28, a pump 30 for supplying the snowmelt water returned to the circulation tank 27 to the boiler 25 via the cold water pipe 29, and a boiler for heating the snowmelt water returned to the circulation tank 27 to form hot water. 25.
Reference numeral 31 denotes a fuel tank for supplying fuel such as oil to the boiler 25.
The melted snow melted in the snowmelt tank 1 is returned to the circulation tank 27 from the circulation pipe 28 at the lower part of the snowmelt tank 1 and supplied to the boiler 25 from the cold water pipe 29 by the pump 30 to become hot water.
Then, it is supplied to the snow melting pipes 23 arranged on both sides of the upper peripheral edge in the longitudinal direction of the snow melting tank 1 through the hot water pipes 26, and hot water is injected from the injection nozzles 24 at a plurality of locations to melt the lump of blocked snow. It becomes snowmelt water and is returned to the circulation tank 27 from the circulation pipe 28 at the lower part of the snowmelt tank 1 again.
A part of the snowmelt water is overflowed and discharged from the overflow port 8 of the snowmelt tank 1 by throwing the lump snow into the snowmelt tank 1.
[0008]
Next, the operation of the snow melting machine of the present invention will be described based on the drawings.
The snow melting tank 1 and the circulation tank 27 are previously replenished with water necessary for circulation so that the operation of the pump 30 is not supported, and the boiler 25 is ignited to make the stored water in the boiler 25 warm.
Lumped snow is put into the snow melting tank 1 by appropriate means, the motor 20 is operated to rotate the stirring cylinder 11, and the pump 30 is further operated.
Then, the lump snow thrown into the snow melting tank 1 is conveyed and melted to the center while being stirred by the left inclined plate 13 and the right inclined plate 14 of the stirring cylinder 11 and from the injection nozzle 24 of the snow melting pipe 23. It is melted directly by the hot water injected.
That is, the massive snow thrown into the snow melting tank 1 is collected by snow removal or the like, and when it is thrown into the snow melting tank 1, it floats near the water surface like an iceberg, and the left inclined plate 13 and the right inclined plate 14 While being sunk or scooped up, the sheet is conveyed to the center along the inclined surfaces of the left inclined plate 13 and the right inclined plate 14, and the blocky snow is melted.
Moreover, since the rotation speeds of the parallel stirring cylinders 11 are different, the stirring and transport operations are efficiently performed, transported while accelerating the collapse of the massive snow, and the massive snow is melted. I am assisting.
A part of the melted snow, that is, the melted water is discharged to the outside from the overflow ports 8 on both sides of the upper peripheral edge in the longitudinal direction of the snowmelt tank 1, and most of the remainder passes through the circulation pipe 28 at the lower part of the snowmelt tank 1. Return to the circulation tank 27.
Then, the snowmelt water is sent from the circulation tank 27 to the boiler 25 via the cold water pipe 29 by the pump 30, is again heated to the hot water pipe 26 and sent to the snowmelt pipe 23, and the lump of snow in the snowmelt tank 1 from the spray nozzle 24. It is injected and melted.
