The present invention relates to an apparatus for removing snow through liquefaction, and more particularly, to an apparatus for removing snow through liquefaction, which melts the snow suctioned by a snow suction means into water, thereby enhancing energy efficiency.
Generally, a method of removing snow deposited on a road in winter season includes a method in which calcium chloride, a chloride solution or the like is loaded in a cargo box of a vehicle and then sprayed using a sprayer while the vehicle travels along the road, a method in which a snowplow is installed at a front side of a vehicle and pushes the snow deposited on the road out of the road while the vehicle travels along the road, a method in which a relatively large amount of snow is forcibly suctioned using a snow blower (a blower-type snow removing machine) and then thrown to a side of the road, a method in which the snow on the road is melted by hot wind blowing from the vehicle and so on.
Among the methods, the method in which the calcium chloride or the chloride solution is sprayed has a problem that it takes a long time to have a chemical action with the snow, and the method in which the deposited snow is pushed out of the road or the method using the snow blower is just moving of a deposition location of the snow by scattering the snow to an adjacent area and corresponds to a snow removing purpose for emergency traffic but has a problem that the deposited snow is not completely removed, and the method in which the snow on the road is melted by the hot wind may have an excellent melting effect when a small amount of snow is deposited but has a problem that the melting effect due to the hot wind is degraded when a large amount of snow is deposited or frozen.
As an example of a conventional snow removing apparatus to solve the problems, there is an “apparatus for removing snow through liquefaction” disclosed in Korean Patent Publication No.10-2006-0108297.
Referring to
Also, the suction part 4a includes a suction duct 4a-1 which is in communication with the snow introduction port la of the snow removing chamber 1, an impeller 4a-2 which forcibly suctions the external snow into the suction duct 4a-1 and a driving motor 4a-3 which drives the impeller 4a-2.
In the apparatus for removing snow through liquefaction according to the prior art as described above, when the stirring part is axially rotated while being located adjacent to the ground at a predetermined distance, the deposited snow is crushed and scattered toward the impeller 4a-2. At this point, the impeller 4a-2 forcibly suctions and supplies the snow into the suction duct 4a-1.
The snow passed through the suction duct 4a-1 is injected into the snow removing chamber 1 through the snow introduction port 1a. The snow injected into the snow removing chamber 1 is melted and dropped by the hot air discharged from the hot air means 5.
Water drops dropped by the hot air is collected in the immersion part 2, and the water overflowing the immersion part 2 is discharged to an outside through the drain hole 1b and melts the snow remaining at a rear of the snow removing chamber 1.
Also, the snow in the snow removing chamber 1 which is not still melted by the hot air is dropped into the immersion part 2 and then melted by contact with a water surface in the immersion part 2. At this point, the hot wire 3 may be heated and thus may increase metability of the snow by heating the water in the immersion part 2.
However, in the apparatus for removing snow through liquefaction according to the prior art, there is a problem that the snow is dropped into the snow removing chamber 1 and liquefied by the hot wire 3 in the immersion part 2, and a high calorific value is required to liquefy the snow and thus a lot of energy is consumed by driving the hot air means 5.
That is, it takes a considerably time to melt the snow introduced into the snow removing chamber 1, and the high calorific value is also consumed by heating a large amount of melted water stored in the immersion part 2, and thus there is a problem that there is a limit to a heating temperature of the melted water and the metability is degraded due to a low temperature of the melted water.
The present invention is directed to providing an apparatus for removing snow through liquefaction, which melts the snow suctioned by a snow suction means into water, thereby enhancing energy efficiency.

The moving means 50 is movable in a state in which the snow suction means 10, the water spray means 20, the storage part 30 and the heating means 40 are loaded therein. The moving means 50 may be a vehicle and may also be formed in a separate cart shape or a shape in which a wheel or the like is installed at a small engine to be conveniently used in a road or the like that it is difficult for the vehicle to enter.
On the other hand, the apparatus 100 for removing snow through liquefaction according to the present invention may be installed in a fixed method without the moving means 50 to remove the snow moved and accumulated by a dump truck or the like.
Also,
Also, a water spray line 60 is installed at the drain hole 33 formed at the storage part 30, and a suction line 61 which may suction the water, the snow or the like is installed at the venturi tube 23 to suction the snow deposited on an area in which it is difficult for the moving means 50 to be moved or to suction the melted water after the snow is melted by the water sprayed from the water spray line 60, and thus the snow may be removed.
And the water spray line may be installed by branching a pipe from the pipe line 21.
Also, a second water spray line 24 which is branched from the pipe line 21 to spray the water may be installed at an inside of the hopper 23a of the venturi tube 23 to allow the snow to be removed.

In the embodiment, when the water flows through the venturi tube 23, the snow may be melted by the water while introduction of the snow provided from the hopper 23a is rapidly performed. The snow may be effectively removed through the water spray line 60 and the suction line 61 even at the area in which it is difficult for the moving means 50 to be moved, and a snow removing operation may be more effectively performed by installing the second water spray line 24 and the second heating part 25 inside and outside the hopper 23a of the venturi tube 23, respectively.
Also,
Meanwhile, in the embodiment, one embodiment is added to
In the embodiment, the water is sprayed into the snow suction means 10 through the pipe line 21 by an operation of the pump 22 to melt the snow, and when the melted water is introduced again into the venturi tube 23 through the hopper 23a, a vacuum state is formed while the water is sprayed from the inlet port 23b of the venturi tube 23 and discharged to the outlet port 23c through the reduced cross section, and thus the snow may be more rapidly melted into the water.
The apparatus 100 for removing snow through liquefaction according to the present invention may be installed at the moving means 50 such as the vehicle to be movable. The snow suction means 10 is operated on the road on which the snow is deposited, and the external snow is forcibly crushed and stirred by operating the stirring blade 11a with the stirring blade driving part, and when the impeller 12b is driven by the driving motor 12c, the snow is suctioned by the impeller 12b and then introduced into the storage part 30 through the suction path 12d.
At this point, the water is sprayed to the introduced snow through the water spray means 20, and the water in the storage part 30 is sprayed into the suction path 12d by the pump 22 installed at the pipe line 21, or the snow dropped from the suction path 12d is injected into the hopper 23a, and when the water is sprayed into the inlet port 23b of the venturi tube 23, the snow injected into the hopper 23a is changed into the water while passing through the reduced cross section and being rapidly discharged to the outlet port 23c and then stored in the storage part 30, and the water spray means 20 may be simultaneously operated.
Meanwhile, the water stored in the storage part 30 is dropped into the inner storage part 31. When the water is increased to a predetermined level, the water is discharged to the outer storage part 32 through the discharge holes 31a. The water stored in the outer storage part 32 is heated by the heating means 40 and sprayed to the snow by the water spray means 20.
Also, the heating plate 34 for evaporating the water may be installed at the inner storage part 31, and thus the water therein may be evaporated by the heated heating plate.
In the heating means 40, the fuel is burned in the burner 41, and the combustion heat is introduced into the first header 42, and the combustion heat in the first header 42 exchanges heat with the water while moving through the exhaust pipes 43.
In addition, the combustion heat which exchanges heat through the exhaust pipes 43 is discharged to an outside. At this point, the combustion heat is discharged to the flue through the heating part 45 formed at the suction path 12d of the snow suction means 10, and a part of the exhaust heat exchanges heat while being discharged from the second heating part 25 outside the hopper 23a of the venturi tube 23, and thus the snow removing operation is effectively performed.
Also, the second water spray line 24 is installed inside the hopper 23a of the venturi tube 23 so that the snow or the water injected into the hopper is easily introduced into the venturi tube.
At the area in which it is difficult for the moving means 50 to be moved, the water is sprayed from the water spray line 60 branched from the pipe line 21 to melt the snow, and the water or the snow is suctioned through the suction line 61 connected to the reduced cross section of the venturi tube 23, and thus the snow removing operation is performed.
Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
