Description

TECHNICAL FIELD The present invention relates to a snow melting treatment apparatus capable of efficiently and massively removing a large amount of snow removed in front of a residential area entrance, in front of a garage, or on a roof in an urban area.

[Problems to be Solved by Conventional Techniques and Inventions] Various conventional snow melting methods, particularly road snow melting methods that spray water on the road surface, non-sprinkling snow melting methods that pass hot water under the road surface, or bury a heat panel, etc. The initial cost and / or running cost are very expensive.

For this reason, it should be applied only to important roads with frequent traffic, and when it comes to snow from small alleys or roofs, or snow in gardens such as gardens, people manually remove snow to the snow melting section of the road or use dump trucks. It was necessary to bring snow to rivers and open spaces using a shovel car, etc. to remove snow, which was very expensive and extremely uneconomical.

On the other hand, a snow drift ditch, a melting snow ditch, etc. require a large amount of water source (river water, groundwater source, etc.) because it is a method of throwing snow into a large amount of water flow and melting the snow mass. It was

The present invention proposes a snow melting treatment device which solves the above drawbacks.

[Means for Solving the Problems]

 The detailed description will be made with reference to the accompanying drawings.

The snow charging tank 1 is buried in the surface of the ground so as to be able to absorb the geothermal heat, the snow charging opening 2 with the opening / closing lid 2'is provided at the upper part of the snow charging tank 1, and the drain pipe 4 leading to the drainage groove 3 is provided at the upper part of the side wall 1 '. Is provided
A water sprinkling device 5 is provided on the upper part to sprinkle the snow in the snow throwing tank 1 to melt the snow, and the circulation pump 6 that sucks the snow melting water from the snow throwing tank 1 from the bottom of the snow throwing tank 1 and circulates the water from the water sprinkling device 5.
The present invention relates to a snow melting processing device, characterized in that the air injection pipe 7 is provided at the bottom of the snow charging tank 1.

[Examples and operations]

The embodiment shown in the accompanying drawings employs a snow throwing tank 1 having a width of 0.6 m, a height of 1 m, and a length of 7.6 m.

The opening / closing lid 2 ′ provided on the upper part of the snow throwing tank 1 is opened to open the snow throwing port 2.

In this case, the opening / closing lid 2'may be formed on the whole, or several pieces may be provided side by side.

A drainage pipe 4 leading to the drainage groove 3 is provided on the side wall 1'at a high portion of the snow throwing tank 1 which is higher than the water storage height.

Similarly, a circulation pump 6 and a water sprinkler 5 for sprinkling snow melting water by the circulation pump 6 are provided in the snow charging tank 1 so that water can be sprayed over a wide range.

A compressor 8 for ejecting air from the air ejection pipe 7 is placed in a garage or the like on the ground, and the air ejection pipe 7 is arranged at the bottom of the snow throwing tank 1.

As shown in FIG. 1, a heating device using a geothermal heat pipe 9, a far infrared radiation heating device 10 or the like may be provided to supply heat.

Fig. 2 shows an example of the actual construction.

This snow melting tank will be installed on the road or on the border of the ground, and will handle the snowfall in front of the entrance and the garage and the mechanical snow removal levee on the road.

Fig. 3 is a layout of this device for roof snow treatment, which is a system for snow treatment with almost no manual input by using it together with a natural snowfall roof.

Results of the experiment The snow treatment amount in the one-winter period in the snow input tank 1 having a size of 0.6 m × 1 m × 7.3 m in FIG. 1 is as follows.

Condition Compressor air flow 1m / min Water circulating water flow 100-200l / min Water temperature 0.1-1.5 ℃ Water tank capacity 4.4m ³ Number of snow days 54 days Snow density 0.2 Snow treatment amount 8100 hours after operation 1100-1300kg (weight) Snow treatment amount per day 2200 to 2600kg Snow treatment amount per winter 118t to 140t In addition, it may be installed so that the snow on the roof can be slid and introduced by a guide gutter, so that it can be introduced with human power assistance added. May be designed.

Reference numeral 11 in the figure is a screen plate.

〔The invention's effect〕

Unlike the conventional snow ditch system, the present invention does not require a water source, and the initial cost and running cost are significantly lower than those of a snow melting device that uses a heat source such as boiler electrothermal heating.

Since the snow throwing tank is formed under the ground, it absorbs the geothermal heat from the entire outer circumference and warms the inside of the tank, and the snow melting water in the snow throwing tank is always absorbed from the bottom side by the circulation pump and from the top. The upper and lower parts are always maintained at a constant level of 0.5 to 1.5 ° C because a circulating water sprinkling system is used to sprinkle water. In addition, air jets are used in combination to stir the snow mass by blowing air and circulating water. The fact that the actions are performed well will be integrated, and the snow melting will proceed extremely efficiently.

Since it is only necessary to repeat the work of throwing in new snow, the snowmelt time zone can be used at any time body of the user without being limited like a snow ditch, and there is concern about the groundwater source utilization type ground. There is no need to worry about groundwater damage such as subsidence and well erosion.

The running cost is about 25,000 yen per winter period (54 days) in the construction example in Fig. 2 and 1/4 to 1 of the boiler heating method.
It's / 5 cheap.

In addition, since it only needs to be cleaned once every three years, the management cost is lower than that of the conventional snow melting equipment, and the management work is extremely simple.
