Abstract

PURPOSE:To promote thermal efficiency and, at the same time, to facilitate cleaning of a device or repairing work by bearing a snow melting cylinder and a burner in a floating state, and making it possible to perform melting of snow and thermal transfer on the whole circumference of the snow melting cylinder. CONSTITUTION:A main body frame is buried in the ground except an upper opening, and the inside of the main body frame is divided into a burner chamber 30 and snow melting chambers 1 and 2 with partition boards 3, 19 and 29. A hot wind from a burner 26 provided to the burner chamber 30 is blown to the inside of a snow melting cylinder D in the snow melting chambers 1 and 2, and snow is melted around it. In such a buried snow melting device, the snow melting cylinder D is borne inside the snow melting chambers 1 and 2 in a floating state through a machine frame 6, and the burner 26 is also provided to the inside of the burner chamber 30 in a floating state. So, a passage for snow melted water is formed downward of the snow melting cylinder D, and melting of snow and thermal transfer are performed on the whole circumference of the snow melting cylinder D.

DISCLOSURE OF THE INVENTION The present invention relates to a buried snow melting apparatus which is buried in the ground and can start the snow melting work immediately by opening the lid only when snow falls in winter. By preventing the snowmelt tube from being immersed in the snowmelt water during non-snowmelt storage other than winter, and by constructing a passage for the snowmelt water under the snowmelt tube, snowmelt and heat are all around the snowmelt tube. Is configured to be moved to improve the thermal efficiency of the buried snow melting device. Also,
By separately supporting the snow melting cylinder or burner and the main body frame, during non-snow melting work, the snow melting cylinder or burner can be easily attached and detached, and the difficulty of cleaning or repairing because it is an embedded snow melting device is improved, The structure is designed to facilitate cleaning of mud accumulated inside the body frame below the snow melting tube, and to facilitate inspection and repair during the summer.

[0004]

The present invention has the following configuration in view of such a point. The main body frame is buried in the ground leaving the upper opening, the inside of the main body frame is divided into a burner chamber and a snow melting chamber by a partition plate, a snow melting cylinder is arranged in the snow melting chamber, and a burner is arranged in the burner chamber. Then, blowing hot air from the burner into the snow melting cylinder, in an embedded snow melting device that melts snow around the snow melting cylinder in the snow melting chamber, the snow melting cylinder is supported in a state of being floated inside the snow melting chamber via a machine frame, A burner attached to the snow melting tube is also floated inside the burner chamber, and a passage for the snow melting water is formed in the lower part of the snow melting tube.

[0005]

[Operation] Next, the operation will be described. In the snow melting chamber of the main body frame 4, the snow melting cylinder D is supported in a floating state via the machine frame 6, and the burner 26 is supported in a floating state in the burner chamber 30. When cleaning and repairing the buried snow melting device, the burner 26 and the snow melting cylinder D can be easily attached and detached, and the mud accumulated on the lower surface of the snow melting cylinder D can be easily removed. I can. Further, when the lid body 5 is closed in the snow melting end state, even if the snow melting water is still accumulated under the snow melting cylinder D, a gap is formed between the bottom surface of the main body frame 4 and the lower surface of the snow melting cylinder D. Since the snow melting cylinder D is less likely to be directly immersed in the snow melting cylinder D, rusting of the snow melting cylinder D due to rotten water hastened, and mud adhered to the surface of the snow melting cylinder D did not solidify. Further, since a gap is formed on the lower surface of the snow melting cylinder D, heat can be transferred from the periphery of the lower surface of the snow melting cylinder D to snow and snow melting water.
Since the heat from No. 6 can be efficiently transferred to the snow and the snowmelt water, the snowmelt efficiency can be improved.
