Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the technique described in Patent Document 1 uses warm water obtained by reusing the hot water for bathing as a heat source for melting snow, but there has been a demand for a snow melting system that melts snow more effectively and efficiently. Also, unlike existing underground buried snow melting tanks, there is no need to dig and bury deep holes in the ground, aiming to reduce construction costs. Above all, eliminating the operation of moving snow to the snow disposal site by dump trucks, reducing many moving vehicles, and realizing a more livable environment in cold and snowy areas such as Hokkaido that are friendly to the environment has been demanded.

[0009] According to this invention, a snow melting system can be provided that effectively and efficiently melts snow. [Brief explanation of the drawing]

[0010] [Figure 1] This diagram shows the configuration of a snow melting system according to the first embodiment of the present invention. [Figure 2] This diagram shows the usage state of the snow melting system according to the first embodiment of the present invention. [Figure 3] This diagram shows the configuration of a snow melting system according to a second embodiment of the present invention. [Modes for carrying out the invention]

[0011] First, with reference to Figure 1, the snow melting system of the first embodiment of the present invention will be described. The snow melting system 1 is installed, for example, in the garden of a private house, on the outdoor premises of a business or convenience store, or on the outdoor premises of a large shopping mall. The snow melting system 1 can be easily assembled, disassembled, and removed, and can be installed in the required location at any time as needed, without having to choose a specific place. For example, it may be assembled and installed in November in the fall, used during the winter, and then disassembled and removed in April in the spring for collection. In this way, the premises can be used more widely and fully for their original purpose outside of winter.

[0012] The snow melting system 1 of this embodiment includes a snow melting tank 10 for accumulating and storing snow, a storage warehouse 20 for storing the snow melting tank 10, a water tank (tank) 30 for storing the melted snow water, a high-performance purification device 40 for purifying the snow melting water, a high-pressure hot water supply device 50 such as a high-temperature boiler for heating and pressurizing the snow melting water, and a storage 60.

[0013] The top surface side of the snow melting tank 10 is open so that snow can be loaded. The method of loading (putting in) snow into the snow melting tank 10 may be to load snow from a snow removal vehicle (such as a shovel car) or by manual labor using tools for snow shoveling, etc. On the inner wall surface of the snow melting tank 10, a water spraying device 11 is provided for spraying heated high-temperature water (heated by the high-pressure hot water supply device 50 described later) onto the snow loaded in the snow melting tank 10 in the form of a shower or mist to promote snow melting. The water spraying device 11 may be a sprinkler or the like, or a mechanism in which a plurality of minute holes are provided in a pipe. On the bottom surface of the snow melting tank 10, a heating device 12 such as a so-called heating mechanism is provided to promote snow melting. As the fuel, the cheapest fuel at that time may be used. If electricity can be used at a low cost and without using fire, it is ideal. The bottom surface of the snow melting tank 10 is provided with a predetermined inclination (gradient) so that the melted snow water, etc. can be guided to the lower side. Also, a groove portion 13 may be provided on the lower side of the inclination to facilitate the discharge of the snow melting water. Furthermore, the bottom or side surface, etc. of the groove portion 13 on the bottom surface side of the snow melting tank 10 may be provided with a known air pump 14, for example, one in which a plurality of minute holes are provided in a hose-shaped object. The air pump releases a large amount of air (bubbles), and the air in the snow and water rises in a bubble form and is stirred, thereby promoting the decomposition and melting of sherbet-like snow. [[ID=十三]] Preferably, the side surface and the bottom surface of the snow melting tank 10 are covered with a heat insulating material, etc. except for the insertion ports of pipes, etc. The snow melting tank 10 can be selected according to the site and usage purpose, with small-sized ones for household use, medium-sized ones for apartment buildings, etc., and large-sized snow melting tanks for stores and large parking lots.

[0014] The storage shed 20 is sized slightly larger than the snowmelt tank 10, and a high-performance heat insulation material is stretched without gaps on the "floor, walls, and ceiling", and there is a little extra space, and the snowmelt tank 10 wrapped in the heat insulation material is stored. For example, it may have dimensions such as a width of 600 mm, a depth of 1800 - 2700 mm, and a height of 900 - 1800 mm. For the storage shed 20, the materials of the outer wall and roof are preferably materials with high durability even when installed outdoors for a long time, and exchangeable materials are ideal. Regarding the roof, a folding plate with a thickness that allows the snowmelt tank 10 stored inside to be taken in and out and removed is ideal. As shown in FIG. 2, the roof (top surface) of the storage shed 20 may have a double - leaf door structure that can be opened (opened) so as to be divided into left and right from the central part and lifted upward. For the snowmelt tank 10 whose top surface side is open to allow snow to be input, various known mechanisms for inputting snow from the outside may be applied and provided. When storing the snowmelt tank 10 in the storage shed 20, either the opening mechanism of the roof (top surface) may be used, or a door, shutter, etc. provided on a separate side surface, etc. may be opened. Preferably, the storage shed 20 is covered with a heat insulation material or the like except for the insertion ports for pipes, piping, etc. Also, with an airtight seal, etc., careful production is required without allowing even a little heat to escape.

[0015] The water tank (tank) 30 is connected to the snowmelt tank 10 through a predetermined pipe or the like (heat insulation material or the like may be wound around it) that continues from the groove portion 13 of the snowmelt tank 10 and stores the snowmelt water. The water tank 30 is, for example, a resin bucket having high - performance heat insulation performance, and weight reduction and rust prevention may be achieved. In addition, a known throw - in heater or a thin heater may be provided, and some heating may be performed at this point.

[0016] A known purification device 40 may be used. It may have a single - line blower pipe or may be of a type that reliably filters and separates suspended substances contained in the snowmelt water in a carrier filtration tank. By purification, the efficiency when the snowmelt water is sprinkled for snowmelt is also increased. The purification device 40 may be attached to the wall surface of the storage 60. Furthermore, the purification device 40 may also be equipped with a drainage mechanism that discharges snowmelt water to road drainage ditches, etc., through a predetermined pipe that penetrates the wall of the storage shed 60. Accumulated snow and its snowmelt water contain foreign matter and debris. For example, if large amounts of snow are piled up in snow disposal sites on riverbanks as in the past, after it melts naturally in early spring, a considerable amount of foreign matter and debris will remain in the riverbank area. If this flows into the river, the water quality will deteriorate, which is not good for the environment in many ways. Therefore, it is necessary to remove foreign matter and debris from the snowmelt water using the purification device 40, protect the soil and water quality of the river, and continuously protect the Earth by protecting the river environment. The water purification device 40 is connected to the water tank 30 by predetermined pipes, etc.

[0017] The high-pressure hot water supply device 50 may be a known type, and it heats and pressurizes the melted snow water to a high temperature of, for example, 70°C to 80°C using a high-temperature boiler or the like, and supplies the high-temperature water at high pressure to the connected sprinkler device 21 (including high-temperature, high-pressure steam piping, etc.). The high-pressure hot water supply device 50 may be mounted on the wall of the storage shed 60. The heater 50 is connected to the purification device 40 by a predetermined pipe or the like. The heater 50 and the watering device 11 are also connected via a predetermined pipe or the like (which may be wrapped with insulating material, etc.), allowing the melted snow water to circulate.

[0018] The storage shed 60 is a facility that houses the water tank 30, the purification system 40, and the high-pressure hot water supply system 50. For example, it may be 900mm wide, 900mm deep, and 2000mm high. It is convenient for repairs and maintenance to consolidate the water tank 30, the purification system 40, and the high-pressure hot water supply system 50 for piping and wiring purposes. All areas except the inlet for pipes and plumbing may be covered with insulation material.

[0019] The operation and utilization flow of the snow melting system 1 of this embodiment will be described in detail below.

[0020] First, regarding the storage shed 20, in order to allow snow to be poured in from the outside, for example, as shown in Figure 2, the roof (top surface) is opened and snow is poured into the snow melting tank 10 using mechanical or manual power. Next, the hangar 20 is sealed from the outside by closing the roof (top surface), for example.

[0021] Next, a watering device 11 installed on the inner wall surface of the snow melting tank 10 sprays heated high-temperature water (heated and pressurized by the high-pressure hot water supply device 50) onto the snow loaded in the snow melting tank 10 in the form of a shower or mist. In addition, a heating device 12 installed on the bottom surface of the snow melting tank 10 promotes snow melting. Furthermore, the bottom surface of the snow melting tank 10 is given a predetermined slope (gradient), which guides the melted snow and snowmelt water to the lower side and collects in the groove 13. An air pump 14 provided at the bottom or side of the groove 13 releases a large amount of air (bubbles), causing the air to rise in the snow and water in a bubble-like form, agitating it and promoting the decomposition and melting of slushy snow.

[0022] Next, the melted snow water is guided from the groove 13 of the snow melting tank 10 to the water tank 30 stored in the storage shed 60 via predetermined piping, etc., and stored.

[0023] Next, the melted snow water is guided from the water tank 30 through designated pipes, etc., to the purification device 40 installed on the wall of the storage shed 60, where foreign matter and debris in the melted snow water are removed.

[0024] Next, the melted snow water is guided from the purification device 40 through designated pipes, etc., to the high-pressure hot water supply device 50 installed on the wall of the storage shed 60, where it is heated and pressurized by a high-temperature boiler, etc., to a high temperature of, for example, 70°C to 80°C. As described above, the high-pressure hot water supply device 50 and the sprinkler device 21 are connected via designated pipes, etc., and the melted snow water circulates. From this point onward, the melted snow water is reused and the sprinkler device 21 directly sprays water onto the loaded snow to melt it, forming a circulating cycle. This is economical and has a significant effect from an environmental perspective.

[0025] In addition, in the snow melting system 1 of this embodiment, when a predetermined amount of snow melt water has accumulated in the water tank 30, etc., the purification device 40 may discharge the excess snow melt water into a road drain or the like through a predetermined pipe that penetrates the wall of the storage shed 60. This prevents pollution of rivers and the like, and furthermore, it becomes possible to simply dispose of the water by ultimately dumping it into a drain.

[0026] According to this embodiment, an environmentally friendly ecosystem that effectively and efficiently melts snow can be realized.

[0027] Next, with reference to Figure 3, a snow melting system according to a second embodiment of the present invention will be described.

[0028] The snow melting system 1' of this embodiment includes a snow melting tank 10 for accumulating and storing snow, a storage shed 20, a water tank 30 for storing melted snow water, a high-performance purification device 40 for purifying the melted snow water, a high-pressure hot water supply device 50 such as a high-temperature boiler for heating and pressurizing the melted snow water, and a storage shed 60. The difference from the snow melting system 1 of the first embodiment described above is that there is no storage shed 60, and the water tank 30, the purification device 40, and the high-pressure hot water supply device 50 are housed in the storage shed 20. Since the other basic components are the same as those of the snow melting system 1 of the first embodiment described above, redundant explanations will be omitted.

[0029] Furthermore, although not given as examples here, this invention may be implemented with various modifications, including changes to the number, size, and shape of each component, as long as they do not deviate from its spirit. [Explanation of Symbols]
