Detailed Description

Embodiments of the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the snow melting vehicle of the first embodiment of the snow melting vehicle of the present invention includes a box body 1, a boiler 4 is installed in the box body 1, and the box body 1 can be opened or closed. The boiler 4 is provided with an independent air inlet and exhaust device, and the independent air inlet and exhaust device is composed of a fan 2, an air inlet duct 3, an air outlet duct 5 and a flap valve 6. The box 1 is composed of a frame and a covering plate (not shown) provided on the frame. Meanwhile, in order to satisfy the maintenance of the devices in the box body 1 by related personnel, a working access door (not shown in the figure) is arranged on the box body 1. When the working access door is closed, a closed space can be formed inside the cabinet 1, and the boiler 4 is installed in the closed space. In this embodiment, a hole, i.e., an air outlet, is formed on the top surface of the box body 1 above the boiler 4, and a hole, i.e., an air inlet, is formed on the bottom surface of the box body 1 below the boiler 4. One end of the air inlet duct 3 is provided with a flange, the circumference of the air inlet is provided with studs corresponding to the hole patterns of the flange, and after a sealing element is additionally arranged, the air inlet duct 3 is fixed through nuts, so that the center of the section of the air inlet duct 3 is coincided with the center of the air inlet. The fan 2 is arranged at the middle section of the air inlet channel 3, and the barrier is arranged in front of the air inlet of the fan 2. The exhaust port of the boiler 4 is connected with the air outlet channel 5 by a connecting flange, and the air outlet channel 5 is connected with the air outlet on the box body 1. A flap valve 6 is arranged on the air outlet channel 5 or the air outlet of the box body 1. It should be noted here that the sealing member used in the air outlet duct 5 should be a high temperature resistant sealing member, which may be a ceramic sinter seal, a graphite seal.

Specifically, in the embodiment, a heating core which generates heat by combustion during operation is arranged in the boiler 4, and air which supports the combustion of the heating core is sucked by the fan 2 arranged at the middle section of the air inlet duct 3 through the air inlet arranged at the bottom of the box body 1, and is sent into the boiler 4 after the flow rate and the flow rate are increased. In the process, the fan 2 directly sucks air from the external atmosphere, so that the combustion oxygen demand of the boiler 4 under any state can be met. The air suction mode does not affect the atmospheric state in the box body 1, so the temperature in the box body 1 is higher than the external environment under the action of heat radiation of the boiler 4 and other equipment, and the box body 1 is closed, so the boiler 4 and other parts can be far away from low temperature damage for a long time. The boiler 4 discharges waste gas through an air outlet channel 5, and a flap valve 6 is arranged at the top of the air outlet channel 5. The flap valve 6 can prevent precipitation, impurities and the like from entering the boiler body when the boiler is not used, and meanwhile, the flap valve also has the function of heat preservation.

The second embodiment of the present invention: the difference with the first embodiment is that the air inlet is arranged on the side surface of the box body. Therefore, the maintenance of personnel is more convenient without climbing the bottom of the vehicle.

The third embodiment of the present invention: the difference from the first embodiment is that the tail end of the air outlet channel is not provided with a flap valve. Therefore, the boiler can exhaust gas more smoothly, the combustion efficiency is improved, and the fuel consumption is reduced.

the structure of the specific embodiment of the snow-melting and heat-supplying device of the present invention is the same as that in the above-described embodiment, and the details thereof are not repeated.
