Description

[0001] The present invention relates to a snow removal equipment with improved thermal efficiency,

The present invention relates to snow removal equipment, and more particularly, to a dissolution snow removal equipment for dissolving and discharging snow by using the heat of a boiler in the loading box after the snow loaded on a road is transported to a loading car of a snow removal vehicle.

Generally, as a method for removing snow accumulated on a road in the winter season, there are a method of spraying the calcium chloride or the chloride solution onto the road using a spreader while the road is running, There is a method of pushing the snowfall and the snowfall to the road side while driving the snow by attaching a snow removal device to the front of the vehicle.

Further, in a method other than the snow removal operation by the above-described spreader and snow remover, it is possible to use a snow blower (snow remover of a blowing type) to forcibly suction a relatively large amount of snow, There is also a way to dissolve the snow on the road by the hot air coming out of the vehicle, such as 'hot snow removal equipment' of Shinan No. 20-0263849.

 However, in general, the roads in the inner city are narrower than the outer roads and the general highways, and the roadside space is narrow, and the snow that is projected to the side of the road by the snow blower is stacked on the roadside as it is. Some parts are melted into the road and froze in the evening when the temperature drops, causing the road to freeze again.

In addition, when the snow on the road is loaded on the road using the snow remover, the snow is not melted after being loaded and remains as a wreck on the road, which is not good for the aesthetics and can be turned into an obstacle threatening the driver especially at night. The melted snow flows into the dry roads, resulting in pollution of roads and driving vehicles.

In addition, in the hot air system, when a small amount of snow is loaded, a good dissolving effect can be obtained. However, when a large amount of snow is piled up or frozen, there is a problem that the dissolving effect by hot air is poor.

Accordingly, there has been proposed a method in which snow accumulated directly on a road by an excavator or a wheel loader is loaded on a loading box rather than using a snow blower, a snow thrower, and a hot air blower to melt snow using the boiler of the loading box. Examples of such a dissolution type snow removal apparatus include a snow melting apparatus of Patent Application No. 2004-27529 and Utility Model No. 2004-11044.

However, the snow melting apparatus takes a long time to melt snow by melting the snow through a single single dissolving operation, and a large amount of heat is consumed by heating a large amount of the dissolved water stored in the melting tank, There is a problem that the heating temperature of the dissolving water is limited and the dissolving power is lowered due to the low temperature of the dissolving water.

In addition, the conventional snow melting apparatus is a simple structure in which the boiler exhaust gas is exhausted after heating the association, and there is a problem that the thermal efficiency of the snow removal vehicle is low by discharging the exhaust gas even though there is sufficient heat energy remaining in the exhaust gas.

Further, a separate dissolving tank may be provided in the loading box 30, and the dissolving tank may be detachably attached to the loading box 30, and may be selectively installed according to a required time and place.

The melting snow removal equipment according to the present invention is provided with a boiler (50) or a burner for generating hot combustion gas for dissolving snow loaded in the loading box (30). The combustion gas generated in the boiler (50) passes through combustion gas pipes (100, 110) provided in the loading box (30).

The boiler (50) to the burner generates a high temperature combustion gas by burning the fuel, and introduces the generated high temperature combustion gas into the combustion gas piping (100, 110).

In addition, the boiler 50 may further include a water tank capable of receiving water, and water vapor obtained by heating the water tank may be introduced into the combustion gas pipes 100 and 110 by the boiler 50.

Therefore, the snow in the loading box 30 is dissolved by the high-temperature combustion gas passing through the combustion gas pipes 100 and 110 or the heat released from the steam. In addition, the combustion gas pipes 100 and 110 may be made of a material having excellent thermal conductivity, for example, copper or aluminum, so as to efficiently transfer heat.

The combustion gas piping 100 and 110 may be installed in the loading box 30 and may be detached from the general loading box 30 and may be mounted on the loading box 30 only when the winter snow removal operation is required. Thereby performing a snow removal operation.

The boiler 50 may include a blower 53 to provide air and a fuel tank 55 to provide fuel to the boiler 50. Further, the control unit may further include a control unit (not shown) for controlling the air blowing device 53 and the fuel tank 55.

The blowing device 53 sucks the high-temperature combustion gas passing through the combustion gas piping 100 and 110 through the blowing device 53 to introduce external air into the boiler 50, . To this end, a separate pipe (not shown) may be provided to connect the gas outlet 103 of the combustion gas pipe 100, 110 to the blower 53.

The controller may adjust the amount of combustion of the boiler 50, the combustion time and the combustion temperature, and adjust the operation amount of the blower 53 and the fuel tank 55. The controller may be a microprocessor computer.

The boiler 50, the air blowing device 53, the fuel tank 55 and the control unit may be provided in the combustion gas chamber 500 which is partitioned from the loading box 30. Accordingly, when the loading box 30 is mounted on the vehicle, the combustion gas chamber 500 may be provided between the cabin and the loading box 30. [

2 to 3, the combustion gas piping 100 and 110 according to the present invention includes a main piping 100 connected to the gas inlet 101 and a combustion gas passing through the main piping 100 And a branch piping 110 provided to be bypassed by two or more paths.

The main pipe 100 is a combustion gas pipe 100 through which the high temperature combustion gas supplied from the boiler 50 flows through the gas inlet 101. The main pipe 100 is connected to two or more branch pipes 110).

The diameter of the branch pipe 110 may be about 2/4 to 3/4 of the diameter of the main pipe 100. In some cases, the diameter of the branch pipe 110 may be the same as the diameter of the main pipe 100 have.

The branch piping 110 increases a path through which the high-temperature combustion gas travels, thereby increasing an area in contact with the snow in the loading box 30. [ Therefore, the snow removal efficiency is increased by increasing the contact area with the snow as compared with the conventional combustion gas pipe.

3, the loading box 30 is connected to the combustion gas chamber 500, and a drain device 200 for discharging the contents in the loading box 30 to the outside is provided on a side surface or a bottom surface of the loading box 30, May be provided.

The drain device 200 may be provided only on a bottom surface or a lower surface of the loading box 30 to discharge water generated in the loading box 30 to the outside.

4 shows a boiler 50 according to the present invention, combustion gas lines 100 and 110 and a blower 53 or a fuel tank 55 mounted together in the boiler 50. As described above, the melting snow removal equipment according to the present invention can be installed and operated in the loading bay 30 of the vehicle. In some cases, the components such as the combustion gas pipes 100, 110 and the boiler 50 may be separated or combined It can be installed and used as needed.

The high-temperature combustion gas supplied from the boiler (50) passes through the combustion gas piping (100, 110) in the loading box (30). The combustion gas pipes 100 and 110 have a gas inlet 101 at one end and a gas outlet 103 at the other end. The gas inlet 101 is connected to the boiler 50.

 The high-temperature combustion gas entering the gas inlet 101 passes through the combustion gas pipes 100 and 110 and is discharged to the gas outlet 103. The gas inlet 101 and the gas outlet 103 are provided with one or more A bent portion or a curved portion may be provided.

The provision of the bent portions in the combustion gas pipes 100 and 110 increases the contact area between the eyes in the loading box 30 and the combustion gas pipes 100 and 110 to facilitate the melting of snow.

In addition, the combustion gas piping 100 and 110 may be provided with a portion having a diameter different from that of the bent portion. For example, the diameter of the combustion gas pipes 100 and 110 may be varied to control the passage speed of the high-temperature combustion gas passing through the combustion gas pipes 100 and 110.

3, by providing the branch piping 110, the back pressure in the combustion gas pipes 100 and 110 is increased to delay the time for the high-temperature combustion gas to move have.

The combustion gas pipes 100 and 110 may be connected by connecting pipes having different diameters. The reason for changing the diameter is to delay the moving time of the high-temperature combustion gas passing through the combustion gas pipes 100 and 110.

That is, the combustion gas piping (100, 110) is formed as a thick tube to supply the high-temperature combustion gas introduced from the boiler (50) to the eyes with high heat at an early stage. So that the back pressure in the combustion gas pipes 100 and 110 is increased.

Therefore, in the initial stage of the discharge, the thick combustion gas pipes 100 and 110 are installed, and thereafter, a relatively small-diameter pipe is provided to form a back pressure on the connection portion between the large-diameter pipe and the small pipe, It is possible to delay the discharge of the combustion gas to the atmosphere.

As such, the portion of the two pipes of different diameters can be connected to each other by a member called a reducer.

In order to increase the back pressure of the combustion gas pipes 100 and 110, a bent pipe called an elbow may be installed. The elbow is used as a connection pipe for increasing the combustion gas discharge path, but an additional back pressure can be formed by changing the combustion gas flow path in the combustion gas pipes 100 and 110.

Preferably, the reducer and the elbow are formed from the gas inlet 101 of the combustion gas pipe 100, 110 in the order of a reducer and an elbow.

 5A shows a flue gas piping 100, 110 according to a first embodiment of the present invention. That is, the combustion gas pipes 100 and 110 include a main pipe 100 connected to the gas inlet 101, a branch pipe 110 branched from the main pipe 100 and adapted to bypass a high temperature combustion gas, And a gas outlet 103 through which a high temperature combustion gas is discharged.

The combustion gas pipes 100 and 110 according to the first embodiment of the present invention are provided with two branch pipes 110 having a diameter smaller than that of the main pipe 100. The combustion gas passing through the main pipe 100 passes through a reducer And the first elbow to the two branch pipes 110, respectively.

The combustion gas introduced into each of the two branch pipes 110 joins at the outlet of the two branch pipes 110, passes through the second elbow, and then moves to the gas outlet 103.

Here, the two branch pipes 110 may have the same diameter, and in some cases, the diameters of the two branch pipes 110 may be different from each other. At this time, the speed and amount of the high temperature combustion gas can be selectively controlled by the difference in pressure in the branch pipe 110.

FIG. 5B shows the combustion gas lines 100 and 110 according to the second embodiment of the present invention. As shown in FIG. 5B, the branch pipe 110 may be provided at a position adjacent to the gas outlet 103.

The branch piping 110 is provided with a gas discharge port 103. The branch piping 110 is branched from the gas discharge port 103 and bent in a downward direction so that the combustion gas piping 110, A part of the gas is discharged through the gas discharge port 103 and the rest is discharged in the direction of the inside of the loading box again through the branch pipe 110.

At least one branch piping 110 may be provided between the main piping 100 and the gas discharge port 103, as the case may be.

5C shows the flue gas piping 100, 110 according to the third embodiment of the present invention. 5c, two branch pipes 110 branched from the main pipe 100 are provided, and one of the branch pipes 110 is connected to the gas outlet 103 and the gas outlet 103 so as to discharge the high- And the other end is closed.

The combustion gas introduced into the other branch piping 110 forms a back pressure at the inlet of the branch piping 110 to delay the progress of the combustion gas from the main piping 100 toward the gas exhaust port 103.

Accordingly, it is possible to increase the time for the high temperature combustion gas to pass through the branch pipe 110, thereby increasing the efficiency of the snow removal.

An agitator (not shown) for agitating the dissolved snow may be additionally provided in the loading box 30 or the dissolving tank of the melting snow removal equipment. That is, the snow dissolved by the heat emitted from the combustion gas pipe (100) can be circulated in the loading box (30). In addition, the water in the relatively high temperature portion can be mixed with the water or the water in the relatively low temperature portion by the stirrer.

Further, the dissolution snow removal equipment according to the present invention may further include a stirring pump (not shown) or a water injection device (not shown). The water injector may increase the dissolution rate by spraying the water generated by dissolving snow into the undissolved eye.

The stirring pump is a device for forcibly generating a flow of water at the bottom of the loading box 30, and various types of axial flow and centrifugal pumps can be used. The flow generated by the stirring pump is preferably formed such that the upper surface of the snow-melted water is directed to the front side of the loading box 30. [

This is because the gas inlet 101 in which the high-temperature combustion gas discharged from the boiler 50 is first guided is disposed at the front, and the device for delaying the discharge of the combustion gas into the atmosphere at the gas outlet 103 is disposed forward As shown in FIG. That is, there may be more heat energy to be supplied from the front of the loading box 30 than from the rear.

In order to smoothly perform the flow of the water, a screen (not shown) for filtering the float may be installed on the rear side of the loading box 30 downstream of the stirring pump along with the flow of water. Accordingly, the float contained in the flowing water is accumulated on the downstream side of the stirring pump, so that even when the floating water is accumulated on the screen and the flow of the water through the screen is impossible, the flow of water can be normally performed in the remaining portion.

Impurities accumulated in the lower portion of the screen or the loading box 30 can be discharged through the drain device 200 or the sludge discharge door formed on the side of the loading box 30.

The water jetting device is installed on the front side of the loading box 30 to form a negative pressure to help flow the water and spray the relatively high temperature water to the loading box 30 to dissolve the snow in the loading box 30 Help. The water jetting device includes a circulation pump (not shown) and a strainer (not shown) for sucking water on the front side of the loading box 30 and water injected by the circulation pump onto the loading box 30 And may include separate piping and injection nozzles.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and simple substitution, modification and alteration within the technical spirit of the present invention will be apparent to those skilled in the art.

The melting snow removal equipment according to the present invention can be used in a dissolution snow removal equipment having a high thermal efficiency by increasing a contact area between a combustion gas pipe and a snow where a high temperature combustion gas moves.
