Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a connected tank type heat storage tank.

Prior Art Figures 5 and 6 show an overview of conventional heat storage tanks of this type. Figure 5 shows a connected tank type heat storage tank using a sink weir system, in which cold water is connected between adjacent heat storage tanks a. In the case of , the water overflows the partition wall b as shown by the arrow x, and in the case of hot water, the water overflows the partition wall b as shown by the arrow y.

Figure 6 shows a connecting tank type heat storage tank using a communicating pipe system, with upper and lower communicating pipes c connected to each partition wall b of adjacent heat storage tanks a1 and a2.
1 and c2 are arranged.

Problems to be solved by the invention In the above-mentioned sink weir type connected tank type heat storage tank, temperature stratification is likely to occur in the tank, and the efficiency is good, but it is necessary to change the flow direction depending on whether the water is cold or hot. In addition, in a connected tank type heat storage tank using a communicating pipe system, heat storage tank A1 is used for cold water, and heat storage tank A is used for hot water.
2 becomes inefficient, and as a result, a large heat storage tank is required.

Means for Solving the Problems This invention is designed to solve the problem when primary cold water or hot water flows into each tank of a connected tank type heat storage tank using underground double pits of a building. Hot water flows into the upper part of the tank near the water surface, and conversely, cold water flows out from the upper part of the tank and hot water flows out from the lower part of the tank, which facilitates thermal stratification and improves efficiency. In view of the fact that it is good, it was proposed to solve the problems of the conventional heat storage tank described above by making it possible to change the inflow and outflow positions of cold and hot water without changing the flow direction of the cold and hot water. In a communication pipe in which an inflow pipe and an outflow pipe extend vertically from both ends of the horizontal pipe in opposite directions between the side walls of adjacent heat storage tanks, the horizontal pipe is rotatably penetrated. The invention relates to a connected tank type heat storage tank characterized in that a float is mounted near the tip of the inflow pipe, the specific gravity of which is heavier than that of hot water, and the specific gravity of which is lighter than that of cold water.

Function Since the present invention is constructed as described above,
When transferring cold water from one heat storage tank to the next adjacent heat storage tank, the float installed near the tip of the vertical inflow pipe at one end of the communication pipe is smaller than the specific gravity of the cold water. It floats in the cold water in one of the heat storage tanks, and as a result, the horizontal pipe of the communicating pipe rotates between the side walls of the adjacent heat storage tanks, and the vertical outflow pipe at the other end of the communicating pipe moves to the next one. The cold water in one of the heat storage tanks flows downward into the next heat storage tank from the bottom of the same tank through the inflow pipe, horizontal pipe, and outflow pipe in the communication pipe.

In addition, when transferring hot water between the two heat storage tanks, the float installed near the tip of the vertical inflow pipe in the communication pipe is heavier than the hot water, so the inflow pipe is transferred into the hot water of one of the heat storage tanks. The communicating pipe rotates in the opposite direction, and the hot water in the one heat storage tank flows into the next heat storage tank through the inflow pipe, horizontal pipe, and outflow pipe in the communication pipe. It flows in from the top.

Example The present invention will be described below with reference to the illustrated embodiments.

1 and 1' are adjacent heat storage tanks in a connected tank type heat storage tank, 2 is a horizontal pipe 2a, and a vertical inflow pipe 2b and a vertical outflow pipe 2c extending in opposite directions are provided at both ends of the horizontal pipe 2a; A float 3 is mounted near the tip of the inflow pipe 2b, which is heavier than the specific gravity of hot water H at 50° C. and lighter than the specific gravity of cold water L at 5° C., and the horizontal pipe 2a is connected to both the heat storage tanks 1 and 1'. It is rotatably inserted into through holes 1a and 1'a provided in the side wall of.

In the figure, reference numerals 4 and 5 indicate stoppers for the outflow pipe 2c disposed within the heat storage tank 1'.

Since the illustrated embodiment is configured as described above, when transferring the cold water L between the heat storage tanks 1 and 1', the inflow pipe 2b with the float 3 floats in the cold water of the heat storage tank 1, and the communication pipe 2 The horizontal pipe 2a is the heat storage tank 1, 1'
The outflow pipe 2c rotates until it collides with the stopper 5 in the heat storage tank 1' between the side walls of the heat storage tank 1', and the cold water L in the heat storage tank 1 flows into the heat storage tank 1 through the inflow pipe 2b, the horizontal pipe 2a, and the outflow pipe 2c. It flows out from below. (See Figures 1 and 2) Next, when hot water H is transferred between the heat storage tanks 1 and 1', the vertical inflow pipe 2b with the float 3 sinks into the hot water H in the heat storage tank 1, and the communication pipe 2 is the outflow pipe 2c
rotates in the opposite direction until it collides with the stopper 4 in the heat storage tank 1', and the hot water H in the heat storage tank 1 flows into the heat storage tank 1' through the inflow pipe 2b, the horizontal pipe 2a, and the outflow pipe 2c. It flows into the interior from the top.

Effects of the invention As described above, in the connected tank type heat storage tank according to the invention, the horizontal pipe in the communicating pipe has an inflow pipe and an outflow pipe extending vertically from both ends of the horizontal pipe in opposite directions. is rotatably inserted between the side walls of adjacent heat storage tanks, and a float is disposed near the tip of the inflow pipe that is heavier than the specific gravity of hot water and lighter than the specific gravity of cold water, and the hot water is inserted between the heat storage tanks. Alternatively, when transferring cold water, the communication pipe is automatically rotated to change the inflow and outflow positions of the cold and hot water without changing the flow direction, so that the cold water is placed at the bottom near the bottom of the heat storage tank, and the hot water is placed at the bottom near the bottom of the heat storage tank. By flowing into the upper part of the heat storage tank near the water surface, temperature stratification is likely to occur in the tank, thereby improving thermal efficiency.
