Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burner snow melting apparatus which combines a jet burner (combustion burner) with a heat-resistant blower and blows high-temperature and high-speed hot air to melt and remove snow. . 2. Description of the Related Art A conventional snow melting apparatus using a combustion burner is disclosed in Japanese Patent Application Laid-Open No. 2000-186313. In this snow melting apparatus, a heating tank by burner heating is provided on the ground, a snow melting tank and a road heating pipe are buried under the ground, and the heat exchange liquid heated in the heating tank is circulated through the load heating pipe. At the same time, the hot water for snow melting heated in the heating tank is circulated in the snow melting tank,
At the same time as increasing the heat absorption efficiency by spraying the hot water for melting snow on the outer surface of a separate chimney or furnace, or in high-temperature combustion gas,
It is designed to absorb and remove harmful substances in the combustion gas. However, since such a snow melting device indirectly melts snow by warming the circulating water with a combustion burner, it takes a long time to melt the snow. Was also low. [0003] Accordingly, the present invention provides a jet burner using kerosene or gas as a fuel and a high-temperature combustion flame burned by a heat-resistant blower. It is an object of the present invention to provide a burner snow melting apparatus for blowing, melting snow and melting snow. [0004] A burner snow melting apparatus according to the present invention uses a jet burner that blows a high-temperature combustion flame using kerosene or gas as a fuel, and is connected to an outlet of the jet burner to reduce the combustion flame. A heat-resistant blower that sucks and pressure-feeds the combustion high-temperature gas, and a heat-resistant blowpipe or a heat-resistant flexible hose that is connected to an exhaust port of the blower and that supplies hot air to a snow melting point, and is connected to the blowpipe or the flexible hose. And a blowing nozzle having a blowing port for blowing hot air directly to a snow melting point. Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the burner snow melting apparatus of the present invention is connected to a jet burner 1 that uses kerosene or gas as fuel and blows out a high-temperature combustion flame, and is connected to an outlet 2 of the jet burner 1 to suck the combustion flame, A heat-resistant centrifugal blower 3 for pressure-feeding a combustion high-temperature gas (hereinafter referred to as “hot air”), a heat-resistant blowpipe connected to an exhaust port 4 of the blower 3 and supplying hot air to a snow melting point, or a flexible pipe. It comprises a hose 5 and an outlet nozzle 7 connected to the blower pipe and the flexible hose 5 and having an outlet 6 for blowing hot air directly to a snow melting point. In addition, although an ON / OFF power switch (not shown) is provided for manual operation, a snowfall sensor 8 is provided for automatic control, and the jet burner 1 and the blower 3 can be automatically turned ON / OFF. . Further, the connecting point between the blower pipe or the flexible hose 5 and the blowing nozzle 7 may be branched to form a branching structure, and the switching electric damper 9 may alternately switch to blow hot air. [0006] Further, the ejection port 6 of the blowing nozzle 7 is
As shown in FIG. 2, a swivel having an air inlet 11 having an annular flange 10 formed at the tip of the blowing nozzle 7, and having an annular flange 10 pivotally fitted to the annular flange 10 of the air inlet 11. Form a jet port 12.
An arm 13 is attached to the revolving jet port 12, and the arm 13 is connected to a small motor 15 disposed in the vicinity via a revolving arm 14. When the arm 14 is rotated, the revolving jet port 12 is revolved around the air inlet 11 or revolved in a fan-shaped manner within a certain angle range.
As shown in FIG. 1, a long blower pipe or a flexible hose 5 is connected to a blower 3 connected to an outlet 2 of a jet burner 1, and a plurality of blower pipes or a flexible hose 5 are further attached to a tip thereof. Blowing nozzle 7 having swirl type jet port 12
Can also be connected. In addition to the above, as the structure of the blowing nozzle 7, various conventionally known structures can be applied. Next, the operation of the burner snow melting apparatus of the present invention will be described with reference to FIG. FIG. 3 shows an embodiment of a two-story house, in which a jet burner 1 using kerosene or gas as a fuel is installed near a house 17, and a heat-resistant blower 3 is connected to an outlet 2 of the jet burner 1. A branch is made via a switchable electric damper 9 connected to the exhaust port 4 of the engine 3. One of the branched blower pipes and the flexible hose 5 is connected to the blow nozzle 7 arranged along the entrance approach 18, and the other is connected to the blow nozzle 7 arranged along the ridge of the roof 19. In addition, in order to arrange the blowing nozzle 7 on each of the roofs 19 on the first and second floors of the two-story house, a switching electric damper 9 is further provided in the middle to branch off, and hot air is alternately applied to the first and second floor roofs 19 and 19. Can be supplied. Also, the blowing nozzle 7
As shown in FIG. 2, a rotary mechanism including a small motor 15 and a rotary arm 13 is provided so that a large number of jet ports 6 are rotated. In the case of automatic operation, the roof 19 and the outer wall 20
When the snowfall sensor 8 provided in the vehicle detects snowfall, the jet burner 1, the blower 3, the switching electric damper 9, and the small motor 15 are activated. The combustion flame of jet burner 1 is
It is sucked by the heat-resistant blower 3 and is sent as high-temperature combustion gas (hot air) from the exhaust port 4 to the switching electric damper 9 under pressure. By the switching electric damper 9 that is switched at a predetermined time interval,
The hot air is alternately supplied to the entrance approach 18 and the roof 19, and is blown to the entrance approach 18 and the roof 19 from the swirling outlet 6 by the small motor 15 or the like. Therefore, the falling snow is blown off by the hot air jetted from the jet port 6 and is melted by high heat while being blown off. In the case of manual driving, the snow that fell last night is piled up on the entrance approach 19 and the roof 19,
Jet burner 1, blower 3, switching electric damper 9,
Each switch (not shown) of the small motor 15 is turned on to start. Similar to the automatic operation, hot air is blown from the swirl-type outlet 12 to melt the surrounding snow while turning, but when there is a lot of snow, the small motor 15 is not started, that is, the swirl-type outlet 12 is moved. Instead, it is better to blow hot air to melt the snow near the swirl-type jet port 12, and then move it. In addition, as shown on the left side of FIG. 3, a jet burner 1 using kerosene or gas as a fuel is installed near a house 17, and a heat-resistant blower 3 is connected to an outlet 2 of the jet burner 1. Then, to the long flexible hose 5 connected to the blower 3, the blowing nozzle 7 having a single fixed type injection port 16 at the end is connected. Then, the flexible hose 5 is freely moved, and the fixed jet port 16 at the tip of the blowing nozzle 7 is moved.
The hot air directly injected from the hopper can melt the snow mountain 21 collected by a snow removing tool such as a scoop or shovel or the snow mountain 22 brought by a snow removing vehicle. As described above, the burner snow melting apparatus according to the present invention requires the initial cost of 1/5 to 1/10 of that of electricity because of using kerosene or gas as the fuel, and the direct high temperature. The use of the combustion gas (hot air) has an immediate effect, and since high-temperature, high-speed hot air is blown, it is possible to easily melt even hard snow.
