1 is a view showing the appearance of a plastic house collapsed by heavy snow.

Heavy snow is a weather phenomenon in which a large amount of snow falls in a short time. Snowfall sometimes goes beyond snowy natural phenomena and causes unimaginable damage to us. According to the amount of snow piled up to quickly paralyze the traffic in the city, as shown in Figure 1, due to the load of snow, facilities such as the plastic house (50) may cause a lot of damage. As the amount of damage increases with the amount of heavy snow, rapid snow removal is required to prevent the damage caused by heavy snow.

FIG. 2 is a view showing a snow removal device installed in front of a vehicle and a snow removal device spraying chloride solution.

In general, a method for quickly removing snow is to install a snow plow in front of the vehicle to push snow (S) accumulated while driving on the road and to remove snow or chloride solution (C) on the road while driving on the road. There is a method (B) to spray. However, the method of pushing snow removal (A) while driving on the road has a problem of freezing again because snow (S) is accumulated in a part that does not reach the snow removal area, and the method of spraying the chloride solution (C) is a method of remaining amount on the road. Calcium chloride and the like could cause secondary environmental problems due to asphalt corrosion and chloride solution (C). In order to solve such a problem, the snow melting apparatus 10 for dissolving the snow sucked through the snow blower at high heat and discharging it into the dissolved water was used.

3 is a view showing the state of the conventional snow melting apparatus.

The snow melting apparatus 10 that melts snow through the high heat sprayed from the hot air blower according to FIG. 3 has no secondary damage due to corrosion as compared to a snow removing device that sprays snow removing agent, and is compared to a snow removing device that pushes snow removing. There is an advantage in that there is no problem of freezing again due to the remaining amount in the area other than this area.

As shown in FIG. 3, the conventional snow removing apparatus 10 is installed and used on the upper end of the moving means 30 for rapid melting.

It can be seen that. In addition, when the weight of the snow removal apparatus 10 installed in the moving means 30 is high, there is a problem in moving the vehicle. In addition, as shown in FIG. 3, the air blower 300 and the cooling air pipe 400 of the conventional snow melting apparatus 10 are configured in a horizontal direction, and the air heated from the burner 200 is stored in the dissolution tank 800. It was accompanied by a loss of thermal energy until it was delivered to the eye, which in turn led to a problem leading to a decrease in dissolution efficiency.

Figure 4 is a view showing the appearance of the vertical downward hot air blowing type snow melting apparatus according to a preferred embodiment of the present invention.

Accordingly, the inventors of the present invention can transmit the heated air to the dissolution tank 800 in a state where the loss of thermal energy is relatively reduced as compared with the conventional snow dissolution apparatus 10. . In the conventional snow melting apparatus 10 introduced in FIG. 3, the burner 200 has a hot air pipe 300, a cooling air pipe 400, and a dissolution tank 800 formed in a horizontal structure. The burner 200 of the vertical spray snow melting apparatus 100 according to the preferred embodiment of the hot air pipe 300 and the cooling air pipe 400 is connected to the top of the air heated by the burner 200 is moved directly to the structure It can be seen that there is a big difference consisting of the configuration. In addition, the vertical downward hot air spray method snow melting apparatus 100 may be installed in the dissolution tank 800 may be configured to immediately transfer the heat of the burner 200 to the dissolution tank (800). Therefore, heat generated from the burner 200 may be transferred to the dissolution tank 800 in the fastest possible time, and an effect of enabling an efficient dissolution operation may be expected.

It can be heated while moving to the bottom. Therefore, according to the present invention according to FIG. 7, the moving time and the moving distance of the air transferred from the burner 200 to the dissolution tank 800 may be shortened, thereby reducing heat loss. Accordingly, the effect of reducing the time consumed by dissolving a large amount of snow can be expected.

In addition, since the equipment of the vertical downward hot air spray method snow melting apparatus 100 is located at the top can maximize the capacity of the dissolution tank (800) can improve the efficiency of dissolution.

In addition, since the air passing through the cooling air pipe 400 is not affected by the flame F, the air may not rise to a hot temperature. Therefore, the air introduced from the cooling air inlet 450 passes through the outer surface of the hot air pipe 300 heated by the flame F to reduce the heat of the hot air pipe 300 and thus the high heat of the hot air pipe 300. It is effective to prevent safety problems caused by conditions.

The volume of air per unit time introduced from the cooling air inlet 450 and the hot air injection pipe inlet 350 of FIG. 8 may be different.

It may be made of a process (S17-3) to be moved to the cooling air inlet 470. Since the air introduced from the cooling air pipe inlet 450 is not affected by the burner 200 and the flame F, the temperature of the hot air pipe 300 heated by the flame F may be reduced. Accordingly, the hot wind pipe 300 heated by the flame (F) is cooled by the air passing through the cooling air pipe 400 can be expected to the effect that can ensure the stability.

Thereafter, the air passing through the cooling air pipe 400 may be combined with the air passing through the hot air pipe 300 inside the cooling air pipe injection hole 470 to form bubbles together with the dissolved water.

18 is a view showing the flow of bubbles through the collecting pipe in the form of a flow chart according to a preferred embodiment of the present invention.

When bubbles are introduced into the collecting pipe from the cooling air inlet 470 (S18-1), the bubbles are discharged to the outside after being fused in the cooling air inlet 470 to the first discharge port 720 of the collecting pipe 700. After the bubbles are discharged (S18-2), the bubbles are sold (S18-3) from the spout 730, and the process of discharging the bubbles to the second discharge port 740 of the collecting pipe 700 (S18-4) is performed. Can be. In addition, bubbles discharged from the first discharge port 720, the jet port 730, and the second discharge port 740 may be moved to the dissolution tank 800 to generate convection motion (S18-4). In the flow of bubbles according to the present invention, the flow of bubbles through the collecting pipe 700 is not limited to a specific step, and the bubbles are discharged to the first discharge port 720 of the collecting pipe 700 (S18-). 2), the step of discharging the bubble into the blower 730 (S18-3), the step of discharging the bubble into the second discharge port 740 of the collecting pipe 700 (S18-4) is made of a process that is generated at the same time Can be. According to FIG. 18, since the discharge ports are separated in both directions, it is possible to prevent a phenomenon in which bubble supply is disturbed by the pressure of the blower tube.
