Description

[Detailed description of the invention] Industrial application field　　　′ This invention relates to water temperature regulation in aquaculture tanks.

BACKGROUND OF THE INVENTION Conventionally, restaurants or fish stores have installed aquaculture tanks inside the store and have raw fish swimming around for viewing.

Problems to be Solved by the Invention However, in the aquaculture tank described above, the water in the aquaculture tank is cooled in the summer by a cooling device such as a refrigerator, and heated in the winter by a heating device such as an electric heater. and increase the water temperature to 10-25
It is maintained at a temperature of °C, and has the disadvantage that the equipment cost is relatively high because it requires a cooling device and a warming machine.

Means for Solving the Problems In order to solve these problems, the present invention focuses on the fact that well water and groundwater always maintain a temperature of 15 to 18°C, and uses well water or groundwater in a tank. This system is characterized by circulating the water in the culture tank inside the tank while pumping up groundwater, allowing a single device to perform heating in the winter and cooling in the summer at a low cost.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

The upper and lower water pipes 2a + 2b are connected to the lower and upper positions of the tank 1 having an appropriate diameter and height, and the upper and lower water pipes 2
A heat exchanger 5 is installed in the vicinity of the aquaculture tank 6, with upper and lower circulation water pipes 3a and 3b communicating with each other in the vicinity of a and 2b, and a heat exchanger 5 in which the upper and lower circulation water pipes 3a and 3b are communicated with each other through a flexible uneven tube 4 in the tank 1. , the external circulation water pipes 7a and 7b connected to the aquaculture tank 6 are connected to the upper and lower circulation water pipes 3a of the heat exchanger 5.
+ 3 b via the circulation pump 8, and the pumping pipe 9 for well water or underground water is connected to the lower water pipe 2b of the tank 1 via the pump 10, and the overflow pipe 11 is connected to the upper water pipe 2a. 0 Sho, which is made as possible as possible.
In the figure, 12 and 12' indicate a drain port, and 13 indicates a filter tank.

action, effect Next, the effects of the present invention will be explained with reference to embodiment figures.

First, in the present invention, well water or groundwater is pumped into the tank 1 of the heat exchanger 5 by the pump 10 and overflowed from the overflow pipe 11, and the well water or groundwater is stored in the tank 1. The water in the tank 6 is transferred to the aquaculture tank 6 via a circulation pump 8, an external circulation water pipe 7b, a lower circulation water pipe 3b, a flexible uneven tube 4 in the tank 1, an upper circulation water pipe 3a, and an external circulation water pipe 7a. It is possible to perform both heating in winter and cooling in summer by using well water or ground water in the tank 1 while circulating.
The water in the aquaculture tank 6 is maintained at 10°C or more, which is suitable for habitat due to groundwater.
It can be maintained at 25°C with inexpensive equipment, the surface area of the flexible uneven tube 4 in the tank 1 is expanded by the uneven surface, and heat exchange can be performed efficiently. It is effective.
