DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting apparatus capable of effectively disposing a large amount of snow removed from snow.

[0002]

2. Description of the Related Art In northern countries, since the amount of snowfall is large, traffic functions etc. are paralyzed if the snow falling on the city or road is left as it is, so snow removal has conventionally been carried out using a large rotary snowplow. In general, snow was dumped on a large dump truck or the like and dumped into rivers flowing in the suburbs.

[0003] However, since such work is usually performed at night, there is a problem of noise from a large dump truck or the like, and harmful substances in abandoned snow have flown into the river together with the melting of snow, causing environmental problems. Also, the dumping place is limited, and there is a problem that the working conditions are deteriorated due to long-distance transportation and the like. Therefore, expectations have been placed on the development of a device that can treat a large amount of snow that has been removed from snow melting.

[0004] As a snow melting apparatus or a snow melting apparatus disclosed hitherto, a fountain device is provided in a tank so that a hot water of a boiler or a water heater can be fountained to perform a snow melting process in the tank, There has been disclosed, for example, an improved sewage treatment tank of a trickling filter type, in which a heat transfer wire is provided on the bottom thereof, and sewage treatment water is passed to the trickling filter bed to enable snow melting treatment.

[0005]

However, as described above, the snow melting apparatus or the snow melting apparatus does not have a processing capacity and a processing efficiency sufficient to meet the above demand.
Further, even if a large amount of snow melting apparatus or snow melting apparatus is capable of snow melting processing, if the pollution of rivers or the like occurs, the problem cannot be solved essentially.

Accordingly, the present invention is to provide a snow melting apparatus which can perform a large amount of efficient snow melting processing while responding to the above demand and taking the above environmental problems into consideration, and which is less likely to cause pollution of rivers and the like. Is what you do.

The first snow melting device and the second snow melting device can be installed independently and used independently.

In the above-mentioned first snow melting apparatus, if a secondary combustion chamber is provided at an intermediate portion or an end portion of the combustion gas conduit so as to reburn the exhaust gas generated from the combustion chamber, the exhaust gas is exhausted as complete combustion gas. This is preferable. Further, one end penetrates the side surface of the water tank chamber, and a combustion device is attached to this end, and the other end is opened in the combustion chamber, or merges with the combustion gas conduit, or is opened in the secondary combustion chamber. By disposing the burner gas conduit provided in the tank chamber separately from the combustion gas conduit, the processing capacity can be further enhanced.

It moves to the room where it is completely burned and released to the outside air. Further, if a combustion device is attached to one end and a combustion gas conduit having the other end opened to the combustion chamber is disposed in the water tank so as to guide hot air generated from the combustion device, the water in the water tank can be removed. Heating and holding can be performed more reliably and in a shorter time.

If snow is thrown into the water tank kept heated in this way from the snow throwing port, the snow is agitated by the rotary feed mechanism to be melted or made into sherbet and sent to the drainage side.
Spills from drain. In the drainage section, the paper is forcibly fed by a feed mechanism so as not to be clogged even in a sherbet shape.
And it flows into the water storage part of a 2nd snow melting device through a drainage part. In the water storage section, the snow is completely melted by being heated by the heating plate member on the bottom surface.

If snow falls on the crushing and scattering portion of the second snow melting apparatus, the snow is crushed by the rotary blade mechanism and scattered on the water storage portion. Some of the scattered snow falls and adheres to the heated and held heat generating portion, and is melted. Further, the scattered other portion is prevented from being frozen by the fountain of the surrounding water pipe, falls onto the water storage portion heated and held by the heating plate member, and melts snow.

[0016] The water in the water storage section that has been melted flows out of the drainage port, flows into the wastewater sedimentation treatment part, where it is subjected to sedimentation treatment and then drained.
