Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. Since the present invention can be subject to various changes and have various forms, specific embodiments will be illustrated in the drawings and described in detail in the text. However, this is not intended to limit the present invention to a specific disclosed form, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Figure 1 is a drawing showing a greenhouse that collapsed due to heavy snow.

Heavy snow refers to a meteorological phenomenon in which a large amount of snow falls in a short period of time. Heavy snow sometimes goes beyond the natural phenomenon of falling a lot of snow and causes unimaginable damage to us. Depending on the amount of snow that accumulates, it can instantly paralyze urban traffic, and as shown in Figure 1, facilities such as greenhouses 50 can collapse due to the load of snowfall, causing a lot of damage. As the degree of damage increases depending on the amount of heavy snow, rapid snow removal work is required to prevent damage from heavy snow.

Figure 2 is a diagram showing the snow removal device installed in front of the vehicle in operation and the snow removal device spraying chloride solution.

In general, methods to quickly remove snow include a method of installing a snow blower on the front of the vehicle to push the accumulated snow (S) while driving on the road (A), and a method of using a snow remover or chloride solution (C) on the road while driving on the road. There is a method of spraying (B), etc. However, the method of pushing out snow while driving on the road (A) had the problem of re-freezing as snow (S) accumulated in areas that did not reach the snow removal area, and the method of spraying chloride solution (C) had the problem of re-freezing. The presence of calcium chloride, etc. could cause secondary environmental problems due to corrosion of asphalt and chloride solution (C). To solve this problem, a snow melting device (10) was used that melts the snow sucked in through the snow blower (40) with high heat and discharges it as melting water.

Figure 3 is a diagram showing a conventional snow melting device.

The snow melting device 10, which melts snow through high heat sprayed from a hot air blower according to Figure 3, does not cause secondary damage from corrosion compared to a snow removal device that sprays snow removal agents, and is more effective in snow removal than a snow removal device that pushes snow. There is an advantage in that there is no problem of re-freezing due to residual amounts in areas other than the areas where this progress has been made.

As can be seen in Figure 3, the conventional snow removal and melting device 10 is installed and used at the top of the moving means 30 for rapid melting. However, as shown in Figure 3, heavy equipment such as many blowers, motors, and hot air pipes 300 are included in a limited space, so the capacity of the melting tank 800, which is a space for substantially melting snow, is limited to melt a large amount of snow. You can see that In addition, when the weight of the snow removal and melting device 10 installed on the moving means 30 is high, there is a problem in moving the vehicle. In addition, as shown in Figure 3, the conventional snow melting device 10 is configured with a burner, etc. in a horizontal direction, so there is a loss of heat energy until the heated air is delivered to the snow stored in the melting tank, ultimately resulting in a loss of heat energy. This caused problems leading to a decrease in dissolution efficiency.

Figure 4 is a diagram showing a vertically downward hot air injection type snow melting device according to a preferred embodiment of the present invention.

The vertically downward hot air spray type snow melting device 100 of the present invention is similar to the conventional snow melting device 10 in that the air introduced from the outside is heated by the flame F generated by the burner 200 and is sprayed downward. It was designed to overcome the problems of heat energy loss during the dissolution process and the capacity of the dissolution tank.

The present inventor's vertically downward hot air injection type snow melting device 100 includes a burner 200, a hot air pipe 300 connected to the bottom of the burner 200, and a cooling air pipe 400 formed in a structure surrounding the hot air pipe 300. , may include a collection pipe 700. The present invention can operate by heating air introduced from the outside with a burner 200 and spraying it vertically. Accordingly, the vertically downward hot air injection type snow melting device 100 of the present invention can transmit heated air to the melting tank 800 with relatively reduced heat energy loss compared to the conventional snow melting device 10. . While the conventional snow melting device 10 previously introduced in Figure 3 has burners, etc. formed in a horizontal structure, the burner 200 of the vertical injection type snow melting device 100 according to a preferred embodiment of the present invention has It can be seen that there is a big difference in that it is connected to the top of the hot air pipe 300 and the cooling air pipe 400 and moves the air heated by the burner 200 directly below. In addition, the vertically downward hot air spray type snow melting device 100 may be installed inside the melting tank 800 and configured to immediately transfer the heat of the burner 200 to the melting tank 800. Therefore, the heat generated from the burner 200 can be transferred to the dissolution tank 800 as quickly as possible, and the effect of enabling efficient dissolution work can be expected.

Figure 5 is a diagram showing the vertical downward hot air injection type snow melting device of the present invention installed on a vehicle and truck.

The vertically downward hot air spray type snow melting device 100 according to the present invention forms a structure in which the air heated by the burner 200 moves vertically downward, so the size and length of the hot air pipe 300 and the cooling air pipe 400 may consist of a reduced configuration.

Accordingly, the vertical downward hot air spray type snow melting device 100 of the present invention can ensure smooth movement of the moving means 30 by reducing the required load compared to the conventional invention. Accordingly, the mobile means 30 installed with the vertically downward hot air spray type snow melting device 100 can move more smoothly than the mobile means 30 installed with the conventional snow melting device 10, thereby improving work efficiency. Possible effects can also be expected.

Figure 6 is a view showing the vertical downward hot air spray type snow melting device of the present invention as seen from the top.

For a preferred explanation of the present invention, Figure 6 shows a view (A) of a conventional snow melting device 10 viewed from the top and a view (B) of the vertically downward hot air injection type snow melting device 100 of the present invention viewed from the top. I would like to compare and explain. In addition, Figure 6 shows the space where the blower pipe and separate components are stored as (T).

As can be seen in (B) of Figure 6, the space (T) where the blower pipe and separate components are stored is smaller than the space (T) where the blowpipe and separate components are stored in Figure (A). This means that a separate space (T) is not required because components such as the burner 200, the hot air pipe 300, and the cooling air pipe 400 are provided on the upper side of the vertically downward hot air injection type snow melting device 100. Because it doesn't. Accordingly, the advantage of increasing the size of the dissolution tank 800, which is a space for substantially dissolving snow, can be expected.

Figure 7 is a diagram showing the burner, which is a component of the vertically downward hot air injection type snow melting device of the present invention.

In Figure 7, the flame F emitted from the burner 200 is attached to the drawing for a preferred explanation of the present invention. A hot air injection pipe inlet 350 is formed in the hot air pipe 300 according to Figure 7 to allow air to flow in from the outside, and the air introduced from the outside is blown by the flame F generated by the burner 200. It may heat up as it moves to the bottom. Therefore, in the present invention according to Figure 7, the movement time and movement distance of air delivered from the burner 200 to the dissolution tank 800 can be shortened, thereby reducing heat loss. Accordingly, the effect of shortening the time consumed by dissolving a large amount of snow can be expected.

In addition, the capacity of the melting tank 800 can be maximized by placing the components of the vertically downward hot air injection type snow melting device 100 at the top, thereby improving melting efficiency. In addition, the effect of improving the weight to be easily installed and loaded on a means of transportation can be expected.

Figure 8 is a diagram showing a hot air pipe and a cooling air pipe, which are components of the vertically downward hot air injection type snow melting device of the present invention.

As shown in Figure 8, the cooling air pipe 400 may be structured to surround the hot air pipe 300. The air passing through the hot air pipe 300 in Figure 8 is heated by the flame (F) after flowing in from the hot air injection pipe inlet 350, and hot air is transmitted in the downward direction, while the cooling air pipe in Figure 8 ( Air passing through 400) flows in from the cooling air pipe inlet 450, and hot air can move downward in the space (H) between the outer surface of the hot air pipe 300 and the cooling air pipe 400. Additionally, the air passing through the cooling air pipe 400 is not affected by the flame (F) and therefore may not rise to a hot temperature. Therefore, the air flowing in from the cooling air pipe inlet 450 passes through the outer surface of the hot air pipe 300 heated by the flame (F), thereby reducing the heat of the hot air pipe 300 and thereby increasing the high temperature of the hot air pipe 300. It has the effect of preventing safety problems caused by the condition.

There may be a difference in the volume of air per unit time flowing from the cooling air pipe inlet 450 and the hot air injection pipe inlet 350 in Figure 8. In the present invention, the volume of air introduced into the cooling air pipe inlet 450 may be 145 cubic meters (cm³) or more and 155 cubic meters (cm³) or less per unit time, and the volume of air introduced into the hot air pipe inlet 350 may flow in at a rate of 45 cubic meters (cm³) or more and 55 cubic meters (cm³) or less per unit time. Accordingly, the size of the cold steel air pipe inlet 450 may be configured to be larger than the size of the hot air pipe inlet 350.

Figure 9 is a diagram showing the flow of air flowing in from the cooling air pipe and the hot air pipe, which are components of the vertically downward hot air injection type snow melting device of the present invention, in the form of arrows.

For a preferred explanation of the present invention, the flame (F) is shown as a dotted line, and the air flowing in from the hot air pipe inlet 350 is (W1), the air flowing in from the cooling air pipe inlet 450 is (W2), and the hot air pipe ( The space between the outer surface of 300) and the cooling air pipe 400 is indicated by (H). As can be seen in Figure 9, the air introduced from the inlet of the hot air injection pipe 350 may be moved to the bottom via the hot air pipe 300. In addition, the air introduced from the cooling air pipe 400 passes through (H), which is the space between the outer surface of the hot air pipe 300 and the outer surface of the cooling air pipe 400, so the hot air pipe 300 heated by the flame (F) It can be moved to the bottom of the cooling air pipe 400 to lower the temperature. Afterwards, the air introduced from the cooling air pipe 400 and the air introduced from the hot air pipe 300 may be fused inside the cooling air pipe nozzle 470 to form bubbles in the water. Afterwards, the air introduced into the cooling air pipe nozzle 470 may be introduced into the dissolution tank 800 through the collection pipe 700. The present invention according to Figure 9 has the advantage of quickly dissolving snow flowing into the dissolving tank 800 by diversifying the discharge ports discharged into the dissolving tank 800.

Figure 10 is a diagram showing how the air introduced from the hot air injection pipe inlet and the air introduced from the cooling air pipe inlet are fused and discharged from the cooling air pipe injection port.

Figure 10 (A) is a diagram showing the air (W1) introduced from the hot air injection pipe inlet 350 and the air (W2) introduced from the cooling air pipe inlet 450 fused at the end of the cooling air pipe, (B) in Figure 10 is a diagram showing the cooling air pipe injection port 470 formed at the end of the cooling air pipe 400.

For a better explanation of Figure 10, Figure 10 will be divided into drawings (A) and drawings (B). According to (A) of Figure 10, the cooling air pipe 400 may be formed to have a longer length than the hot air pipe 300. Accordingly, there may be a height difference (D) between the cooling air pipe 400 and the hot air pipe 300. Due to the difference in height (D) between the cooling air pipe 400 and the hot air pipe 300, the air (W1) flowing in from the hot air injection pipe inlet 350 and the air flowing in from the cooling air pipe inlet 450 (W2) A fused space (S) may be formed.

In addition, the air W1 introduced from the hot air injection pipe inlet 350 and the air W2 introduced from the cooling air pipe inlet 450 may be discharged in the form of bubbles. According to (B) in Figure 10, there is a cooling air pipe injection port ( 470) can be composed of a configuration that exists. Therefore, the air (W1) introduced from the hot air injection pipe inlet 350 and the air (W2) introduced from the cooling air pipe inlet 450 pass through the cooling air pipe injection port 470 to the collection pipe 700 and/or the dissolution tank. It may be configured to be discharged directly to (800). In addition, the cooling air pipe nozzle 470 formed at the lower part of the cooling air pipe 400 allows air to be discharged consistently and continuously into the collection pipe, thereby reducing noise and vibration of the equipment and improving stability.

Figure 11 is a diagram showing the components of the collection pipe, which is a component of the vertically downward hot air spray type snow melting device of the present invention.

The collection pipe 700 according to Figure 11 may be formed in a cylindrical shape surrounding the cooling air pipe 400. However, the shape of the collection tube 700 is not limited to a cylindrical shape. The collection pipe 700 shown in Figure 11 includes a first discharge port 720 located at the bottom of the collection pipe 700, a second discharge port 740 located at the top of the collection pipe, a first discharge port 720, and a second discharge port. It may be provided with an ejection outlet (730) formed between (740) and an eaves (760) of a plate-shaped structure located at the top of the second outlet (740). The eaves 760 of the plate-shaped structure can prevent air bubbles and dissolved water discharged from the second discharge port 740 from scattering into the air. In addition, the eaves 760, which are a component of the collection pipe 700 according to Figure 11, directly hit the snow stored inside the dissolution tank 800 when bubbles and dissolved water are discharged from the second discharge port 740, quickly dissolving the snow. The plate-like structure may be shaped to face downward. Accordingly, the effect of improving dissolution efficiency can be expected by transferring high temperature bubbles and dissolved water directly into the dissolution tank 800.

Figure 12 is a diagram showing the flow of air bubbles moving from the cooling air pipe injection port to the collection pipe in the form of a schematic diagram.

For a preferred description of the collection pipe 700 according to Figure 12, some components included in the present invention are excluded from Figure 12. According to Figure 12, the hot air moved to the cooling air pipe nozzle 470 is combined with the dissolved water inside the dissolution tank 800 to form bubbles, and is configured to be discharged via the collection pipe 700. . The air bubbles discharged from the cooling air pipe injection port 470 may be moved upward and sprayed in the direction of the second discharge port 740, and at the same time, they may also be discharged in the direction of the first discharge port 720 and the vent 730. there is. Here, when air bubbles and dissolved water are sprayed in the direction of the second discharge port 740, the eaves 760 provided at the top of the second discharge port 740 allow hot air and water to flow into the air through the second discharge port 740. It can serve to prevent heat loss by allowing the emitted bubbles and dissolved water to be discharged in the direction of the dissolution tank 800. In summary, the eaves 760 according to the present invention may be formed in a plate-like shape extending in the lower direction, that is, in the direction of the dissolution tank 800, and the bubbles discharged from the second discharge port 740 through this may be formed. Since it can directly hit the eyes stored in the dissolution tank 800, the effect of improving dissolution efficiency can be expected.

Figure 13 is a diagram showing the flow of bubbles moving from the collection pipe to the dissolution tank in the form of a schematic diagram.

For a better description of the components of the collection tube 700, some components included in the present invention are excluded from Figure 13. The collection pipe 700, which is a component of the present invention, can be installed and driven inside the dissolution tank 800.

According to Figure 13, it can be seen that the collection pipe 700 is configured to include a first discharge port 720, a second discharge port 740, and a discharge port 730. As shown in Figure 13, it can be seen that the directions in which bubbles are discharged from the first outlet 720, the second outlet 740, and the outlet 730 are different. Therefore, when snow and dissolved water accumulate inside the dissolution tank 800, hot bubbles can be delivered evenly to the snow and dissolved water, and the effect of improving dissolution efficiency is to induce hot air and flow throughout the entire area inside the dissolution tank 800. can be expected.

Figure 14 is a view showing a dissolution tank according to a preferred embodiment of the present invention.

The dissolution tank 800 according to Figure 14 may be configured to include a control device 830 and/or an opening and closing device 860. The control device 830 according to a preferred embodiment of the present invention may be configured to discharge the dissolved water inside the dissolution tank 800 out of the dissolution tank when it reaches a certain height or higher. Therefore, it is possible to prevent overflow inside the dissolution tank, and there is an effect of preventing inhibition of work speed due to overflow. Additionally, dissolution water used for dissolving snow may be discharged through the opening and closing device 860. The opening and closing device 860 may be configured to be opened and closed not only during the dissolution operation but also during the cleaning operation at the end of the dissolution operation. The dissolution tank 800 according to Figure 14 may be further equipped with a fuel tank and/or a lubricant tank in addition to the control device 830 and the opening and closing device 860. The form of the dissolution tank 800 according to Figure 14 is the form expressed on the drawing for a preferred explanation of the present invention, and in the present invention, if it can satisfy the original function of the dissolution tank 800, it is limited to any one form. You may not.

Figure 15 is a diagram showing in the form of a schematic diagram the path through which air flows into a vertically downward hot air injection type snow melting device according to a preferred embodiment of the present invention.

For a preferred explanation of the present invention, the air flowing in from the outside will be divided into (W1), which is the air flowing in from the hot air injection pipe inlet 350, and (W2), the air flowing in from the cooling air pipe inlet 450.

According to Figure 15, (W1) is heated by the burner 200 after flowing into the hot air injection pipe inlet 350, and (W1) heated by the burner 200 is heated along the hot air pipe 300. It may descend vertically and flow into the cooling air pipe nozzle 470.

On the other hand, after (W2) flows into the cooling air pipe inlet 450, it may descend vertically along the cooling air pipe 400 and flow into the cooling air pipe nozzle 470. At this time, (W2) can be expected to have the effect of reducing the temperature of the hot air pipe 300 heated by the burner 200 in the process of descending vertically along the cooling air pipe 400. Afterwards, (W1) and (W2) may meet and fuse inside the cooling air pipe nozzle 470, and after being fused inside the cooling air pipe nozzle 470, they may be transferred to the collection pipe 700 and/or the dissolution tank 800. may be discharged. The bubbles and dissolved water discharged from the collection pipe 700 and/or the dissolution tank 800 can smoothly proceed with the dissolution process in the dissolution tank 800.

For smooth operation of the vertically downward hot air injection type snow melting device 100 according to Figure 15, the operation may be performed with melting water introduced into the melting tank 800. The dissolved water introduced in advance can be heated by the vertically downward hot air spray type snow melting device 100 of the present invention to facilitate the melting operation.

Figure 16 is a diagram showing the flow of air introduced into the hot air pipe in the form of a flow chart according to a preferred embodiment of the present invention.

The air passing through the hot air pipe 300 is introduced into the hot air injection pipe inlet 350 by the blower and external configuration (S16-1), and is heated by the flame F generated by the burner 200. (S16-2), the air heated by the flame pipe moves vertically downward within the hot air pipe 300 (S16-3), then moves to the cooling air pipe injection port 470 (S16-4) and can be injected. . In addition, the step of introducing dissolved water into the dissolution tank 800 and/or loading snow into the dissolution tank 800 before the step of introducing air into the hot air injection pipe inlet 350 (S16-1). More may be included. For reference, the volume of air injected into the hot air injection pipe inlet 350 per unit time may be between 45 cubic meters (cm³) and less than 55 cubic meters (cm³) per unit time.

Between 45 cubic meters (cm³) and 55 cubic meters (cm³) per unit time is used for combustion in the burner, and may be the optimal value to ensure that the air is properly heated by the flame (F) to improve dissolution efficiency.

Figure 17 is a diagram showing the flow of air introduced into the cooling air pipe in the form of a flow chart according to a preferred embodiment of the present invention.

The flow of air introduced into the cooling air pipe 400 is after the air flows into the cooling air pipe inlet (17-1), and the temperature of the hot air pipe is reduced while moving inside the cooling air pipe 400 (S17-2). This may be accomplished by moving to the cooling air pipe nozzle 470 (S17-3). 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) can be reduced. Accordingly, the hot air pipe 300 heated by the flame F can be expected to be cooled by air passing through the cooling air pipe 400, thereby ensuring 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 nozzle 470 to form bubbles together with dissolved water.

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

When air bubbles are introduced into the collection pipe from the cooling air pipe nozzle 470 (S18-1), they are fused inside the cooling air pipe nozzle 470 and then discharged to the outside to the first discharge port 720 of the collection pipe 700. After the air bubbles are discharged (S18-2), the process of discharging the air bubbles from the outlet 730 (S18-3) and discharging the air bubbles through the second outlet 740 of the collection pipe 700 (S18-4) is performed. It can be. Additionally, air 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 convective motion (S18-4). The flow of air bubbles according to the present invention is not limited to a specific stage in which the air bubbles flow through the collection tube 700, and the stage in which the bubbles are discharged through the first discharge port 720 of the collection tube 700 (S18- 2), the step of discharging air bubbles through the outlet 730 (S18-3), and the step of discharging air bubbles through the second outlet 740 of the collection pipe 700 (S18-4) are processes that occur simultaneously. You can. According to Figure 18, the discharge ports are separated in two directions, so it is possible to prevent the supply of air bubbles from being interrupted by the pressure of the blowing pipe.

As described above, the present invention has been described with reference to the first and second embodiments, but those skilled in the art will understand without departing from the spirit and scope of the present invention as set forth in the claims below. It will be understood that the present invention can be modified and changed in various ways.
