This is a sectional view taken along line I-1 in the figure. Figure 1~
As shown in FIG. 3, a heat pipe 7 is connected to the pipe 3, and hot air is blown into the vibro circle through the heat pipe 7t to heat the vibro 1. That is, as shown in FIG. 2, a plurality of heat pipes 7 are arranged along the circumferential direction of the vibro to form a heating element group 7At-, and this heating element group 7A is further arranged in the axial direction of the vibro. The heating section C in FIG. 1 is constructed by disposing the heating section C in FIG.

The vibro is made up of a plurality of tubes having different diameters arranged concentrically, and as shown in FIGS. 2 and 3, a first tube 33a and a tube larger than the first tube 33a A second tube 35b with a small diameter, a third tube 66C1 with an even smaller diameter than the second tube 35b, and these tubes 33a to 33.

Further, the conduit 30 communicating with the diesel generator communicates with the cavity 66 of the vibro, and the vibro is made of stainless steel. Heaters 8 are wound around the outer periphery of the heat pipe 7, and these heaters 8 are connected by wiring 41.

As mentioned above, the vibro is heated by blowing hot air from Heat Pigua and heat from the exhaust from the diesel engine generator into the six pipes.

Furthermore, since the heat pipe 7 is preheated or heated by the electric heater 8, the heating efficiency of the vibro is significantly improved.

Next, the operation of the above embodiment will be explained with reference to the flowchart shown in FIG.

First, the diesel engine generator 22 is started to establish voltage. After that, conditions 1 for the ice and snow, which is the material to be melted, the ambient temperature, water temperature, delivery device speed, etc. are set. After these settings are completed and the patient dies, the power control unit 18t is activated by the output of the microprocessor 17 to start operating the air compressor and supply compressed air to the heat pipe 7. Hot air is blown from the heat pipe 7 toward the center of the tube 3 as shown by the arrow 42 in FIG. is turned on, and the heater voltage is adjusted.Meanwhile, the exhaust from the diesel engine generator 22 is led to the pipe 3, and the engine exhaust heat is reused.

When the temperature of the pipe 3 is greater than or equal to the set value, the electric motor 5 is driven to rotate the delivery device 4. At this time,
A snowplow (not shown) starts supplying snow to the packet 2 via the guide pipe 1.

The snow put into the packet 2 is sent to the vibro by the sending device 4. Since the pipe 3 is already heated, the snow that is sent in is melted and turned into hot water. This hot water is stored in a hot water tank 12. The temperature of the hot water in the water storage tank 12 is detected by the sensor 16, and when the temperature is greater than or equal to the set value, the hot water circulation pump of the liquid discharge section F is operated, or when the hot water level is higher than the specified value. Spreader 28f: Spread hot water onto the snow to melt the snow. Also, when the hot water tank 12 is full, the overflow fitting 12b
Hot water flows out through the t-.

When the temperature of the pipe 3 is lower than the set temperature, the heater voltage is adjusted to continue heating. Further, selection control of the heat pipe 7 and the heater 8 is performed depending on the temperature of the vibro and the temperature inside the hot water tank 12. That is, the microprocessor 17 processes the detection signals of the sensors 15 and 16,
This arithmetic processing signal operates the power control unit 18 to selectively control the air compressor 11 and the heater power source, thereby controlling the temperature of the pipe 3.

In the embodiment described above, if it is necessary to further increase the temperature of the hot air blown out from the heat pipe 7,
An induction heating section may also be added. That is, as shown in FIG. 1, an induction heating section 43 is attached to the blast pipe 9 connected to each heat pipe 7, and power is supplied from the power control section 18 through the frequency converter 44. do.

In the melting device attached to the induction heating section 43't, as shown in FIG. 5, when the induction heating section 43 shown in FIG. The frequency conversion section 44 is entirely connected to the induction heating section 46.
control. After that, the power of the heat pipe 7 is turned on, and after adjusting the heater voltage, if the temperature of the vibro is lower than the set value, the power control of the induction heating section 43 and the adjustment of the heater voltage are performed again.

According to the M melting apparatus according to the above embodiment, the apparatus is small because a heat pipe is used as the heating section.

It is lightweight and has excellent temperature rise characteristics.

Also, add F if necessary! Switching of A element group 7A.

Since selective control is possible, optimal heating control is possible.

The heating and melting apparatus shown in FIG. 1 can be mounted on a vehicle 45 such as the tray 2 as shown in FIGS. In the figure, the same parts as in FIG. 1 are designated by the same reference numerals.

Bakubuto 2 is located at the left end in Figure 2 (2), and the current water tank 12 is located at the right end. The bucket 2 and the water tank 12 are communicated with each other through a snow melting pipe 3. The generator 22 and other parts 46 are arranged in the center of the vehicle 45.

When the snow season is over, the hot water tank 121c on the left end of the vehicle 45 (the right end in FIG. 5 fc) is removed and the Ascha Alto paving equipment 48 is installed, and the pipe 3 etc. can be used as is. In addition, Fig. 7 (4).

In (2), 49 is a leveling and stirring device, 50 is a stirring and uniform delivery device, and 51 is a presser plate. Furthermore, if the diesel power generation device 22 is mounted on another vehicle, only the snow melting device will be used. In this way, the overall device can be made smaller, which improves workability in narrow spaces. Furthermore, a belt conveyor is housed in a storage section 47 of the vehicle 45 shown in FIG.

This belt conveyor is used to manually transport the snow to Bakubuto 2, since using a snow plow or bulldozer to dispose of the snow may cause the snow to collapse.

Although FIG. 6 illustrates an example in which the heating and melting device is movable, the present invention is not limited to this, and may be of a fixed type, for example.

H1 Effects of the invention As described above, the invention provides the following advantages.

(1) Conventional snow removal methods remove snow by blowing it away.
This was not possible when the area was surrounded by people's houses, but since the snowplow of this invention is a means of melting snow, work can be done smoothly under overpasses, railroad crossings, crowded areas of private houses, station premises, and cemeteries.

(2) Conventional snow removal methods require the work of transporting snow piles, but the method of the present invention only requires snow melting, making the work extremely simple.

(3) After the snow melts, high-temperature water can be sprayed to melt remaining snow and ice on surrounding fences.

(4) It is safe in terms of security because no open flame is used.

(5) By mounting the power generator on a separate vehicle, the entire system can be made smaller, making it easier to work in narrow alleys.

(6) By melting snow, the work time required for snow removal can be significantly shortened.

(7) The operation of the snowplow of this invention is easy because it is mostly automated, and the number of workers can be reduced.

(8) Since a heat pipe that generates one heat source is used as the heating section, the device can be made smaller and lighter, and economically optimal heating control can be achieved.
