Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hot water storage type snow melting apparatus for melting snow collected by snowfall or the like.

[Conventional technology]

In snowy countries, especially in densely populated areas, there is no place for dumping snow collected due to snowfall, etc., so it is unavoidable that they are often piled up high on roadsides, etc. In addition, the visibility of roads deteriorates, which may lead to traffic accidents, which is a serious problem in the living environment.

In order to deal with such a problem, various types of snow melting devices have been proposed in the past. For example, by throwing snow on an iron plate to melt it, sucking melted warm water (30 to 35 degrees) into a pump and injecting it from the top, or by setting up a combustion chamber in the water of a water storage tank, kerosene in the combustion chamber Is completely burned, the temperature of the water in the tank is raised, and the water is injected from above.

[Problems to be solved by the device]

However, in the case of the above-mentioned conventional snow melting devices, the thermal efficiency is poor, the temperature of the hot water sprayed on the snow is low, and it takes time to melt the snow, which is uneconomical.

Therefore, the present invention aims to provide a hot water storage type snow melting apparatus which has high thermal efficiency and can perform snow melting processing within an extremely short time.

[Means for Solving the Problems]

The present invention provides a water storage tank in which a combustion chamber is arranged so as to be slightly floated from the inner bottom, and a combustion device that completely burns fuel in the combustion chamber is installed in the water storage tank. A water collecting chamber is provided for arranging the water pipes, and the vertical water pipes are communicated with each other at the upper end, and an exhaust duct connected to the combustion chamber is provided on the rear wall of the water storage tank, and a flow space is maintained around the exhaust duct. A water bottle is installed inside the water storage tank, and a circulation pump for taking out high-temperature water in the water collection chamber and sending it into the flow-through space is attached to the water storage tank, and hot water is taken out from the flow-through space to store water. The above-mentioned problems were solved by using a hot water storage type snow melting device in which a shower nozzle for injecting into the tank is installed.

[Action]

When water is filled to a predetermined position in the water storage tank and the combustion device and the circulation pump are operated, the water temperature in the water storage tank gradually rises, and in particular, the hot water that passes through the vertical water pipe and collects in the water collection chamber becomes high temperature. . This high temperature water is sent into the flow space of the water bottle by the circulation pump. As a result, high temperature water is jetted from the shower nozzle.

〔Example〕

 A preferred embodiment of the present invention will be described with reference to the drawings.

The device shown in the drawing has wheels attached thereto so as to be movable. In the figure, 1 is a box-shaped water storage tank equipped with wheels 2, the upper surface of which is open, and a handle 3 is provided at one end of the upper portion.
Is attached. An oil tank 4 is installed in the portion of the handle 3 so as to be surrounded by a pipe material of the handle, and a combustion device 5 which receives oil supply from the oil tank 4 is installed on an outer wall of the water storage tank 1. Combustion device 5
Is equipped with an oil pump and a burner, and the burner is directed to the combustion chamber 6 installed in the lower part of the water storage tank 1. The lower side of the combustion chamber 6 is slightly floated above the bottom of the water storage tank 1 to hold a space. In addition, a plurality of vertical water pipes 7 that vertically penetrate the combustion chamber 6 are installed in the latter stage of the combustion chamber 6 (right half of FIG. 1), and the upper ends of the respective vertical water pipes 7 are opened in the upper part of the latter stage. A water collecting chamber 8 is provided. A strainer is provided in the water collection chamber 8 in order to prevent foreign matter from entering the circulation pump described later. Reference numeral 9 denotes a hot water outlet provided in the water collection chamber 8, to which a suction pipe 11 extending from a circulation pump 10 installed outside the water storage tank 1 is connected. Reference numeral 12 is an L-shaped water cylinder provided on the outer wall of the water storage tank 1, and an exhaust duct 13 communicating with the combustion chamber 6 is provided therein. In that case, a hot water flow space 14 is held between the inner wall of the water bottle 12 and the exhaust duct 13. An exhaust port 15 is provided at the upper end of the exhaust duct 13,
The hood of the exhaust port 15 is directed into the water storage tank 1.
A water pipe 16 is connected to the flow space 14 at the upper end of the water bottle 12, and a shower nozzle 17 for injecting hot water into the water storage tank 1 is installed at the tip of the water pipe 16. 18 is an overflow port installed on the upper side wall of the water storage tank 1, and 19 is the water storage tank 1.
It is a support stand attached to the bottom of the.

In order to explain the operation of the above configuration, first, water is put into the water storage tank 1 to such an extent that the combustion chamber 6 is submerged, and then the combustion device 5
The burner is ignited and the oil supplied from the oil tank 4 is completely burned in the combustion chamber 6. After heating the combustion chamber 6 and the vertical water pipe 7, the combustion gas is exhausted from the exhaust port 15 into the water storage tank 1 through the exhaust duct 13.
The water in the water storage tank 1 is heated. As a result, the water storage tank 1
The water inside is warmed, and in particular, the water stored in the water collection chamber 8 has a high temperature because it has passed through the vertical water pipe 7 having a large area in contact with the high temperature combustion gas. This hot water is a circulation pump
By the action of 10, it passes through the hot water outlet 9 and the suction pipe 11, is fed from the discharge side of the pump into the flow space 14 from its lower part, and is further heated in contact with the exhaust duct 13. Thus, the water in the flow space 14 having a high temperature is taken out from the upper end thereof, passes through the water supply pipe 16, and is sprayed from the shower nozzle 17 into the water storage tank 1. The temperature can reach 50 to 60 degrees.

Then, when snow is poured into the water storage tank 1, the snow will be immersed in the hot water, and the high temperature water and the exhaust gas will be jetted to immediately melt the snow. Thus, the water level in the water storage tank 1 increases, but the excess water is discharged from the overflow port 18, so that snow can be continuously added.

In addition, a temperature sensor is installed in the water of the water storage tank 1,
For example, when the water temperature reaches 50 degrees, combustion in the combustion device 5 is automatically stopped, and when the water temperature falls below 45 degrees, the automatic temperature control device is automatically re-ignited.

[Effect of device]

The present invention is as described above, has a compact configuration,
The combustion heat can be effectively used without waste, the thermal efficiency is good, and the snow melting treatment can be carried out quickly and economically, which is very useful.
