Description

[Detailed description of the invention] The present invention relates to a tank for storing liquid such as water.

In recent years, residential heat utilization systems have become popular (hot water is stored in a tank, and hot water is drawn out directly from the tank or heated via a heat exchanger installed in the tank). There is something I did.

Conventionally, the entire tank used in such systems has been formed with a rigid part that has the strength to withstand water pressure, and is quite large and heavy, making it difficult to transport and expensive to manufacture. In addition, the shape of the tank body is limited, and if it is installed on uneven ground, it will wobble and become unstable, and if a horizontal force is applied due to an earthquake, etc., there is a risk that it will receive this force and fall over. .

Furthermore, if a combustion device or the like is attached to the top of such a tank to heat the water in the tank, the vibrations of the device will be transmitted to the tank body which is a rigid body, creating a speaker structure and causing secondary vibrations, resulting in a large noise. This caused problems such as the occurrence of

The present invention has been made in view of these conventional problems, and includes a tank body made of a flexible material that can be folded freely and an auxiliary frame member made of a rigid material. The outer circumference of the tank part is at least 3
We provide a liquid storage tank that solves the above-mentioned problems by having a structure that includes more than one support leg, a heater that heats the liquid in the main body of the tank, and a heat exchanger that exchanges heat with the liquid. The purpose is to

] The present invention will be explained based on illustrated embodiments.

1 to 3 show one embodiment, which is applied to a hot water storage tank for heat exchange used in a residential heat utilization system. In the figure, the tank body l is formed into a cylindrical bag shape using a flexible, tensile-resistant thin film material made of liquid bamboo RL, and the upper edge of the tank body is formed of a rigid body such as a metal plate or plastic. It is inserted directly into the outer circumferential wall of the flange frame 2, which is a frame, and is fastened to a circumferential groove formed in the outer circumferential wall with a handle 13, and fixed in a tight state. Inside this tank body I, a heat exchanger 4 (not shown in FIG. 2) is installed along its inner peripheral wall. The heat exchanger No. 4: 1. Flexibility and rigid tension between the tank body and the tank body 1! 1. It is made of a resin material containing 1 liter of liquor, for example, by leaving a serpentine or 21-il-shaped passage through two layers of resin, or by inserting a flexible 1 liter in this passage.
(Insert 1 tube and 2) Apply heat treatment etc. to other parts U7
6. Glue everything together. A heat exchange fluid passage 4a is formed from two ends, and connected to both ends thereof: 1 connection 4 = I pipes 4b, 4c are installed by penetrating the tank body 1 in a fluid-tight manner. In addition, a train valve 5 is installed at the bottom of the peripheral wall of the tank body 1.
is installed. The flange frame 2 has an upper edge bent inward, a seal rubber 6 is attached to the inner edge, and a clasp 7 for fastening with a cover, which will be described later, is attached to the outer circumferential wall. Grackles L2a having holes that fit into the two ends of at least three support legs (to be described later) are overhang-molded at three locations at equal intervals in the circumferential direction.

A cover 8, which is an auxiliary frame, is hingedly attached to the top of the flange frame 2 to cover the opening surface of the flange frame 2 freely.

The cover 8 has a ring-shaped flange portion and a bridge portion connecting both ends of the ring-shaped flange portion in the diametrical direction. ! 11A is the same as the tank body 1 which is lined to cover the gap between the frame main body 88 integrally molded in '1, the flan 7 parts and the bridge part! The cover 8 is composed of a membrane cover F, and the center portion of the cover 8 is recessed lower than the outer circumference side portion. In addition, a hole 8a is formed in the center of the frame main body 8, and a hole 8a is formed in the hole 8a to accommodate a heat generating part of an engine, a heat exchanger such as a solar cell, a moxibustion device, etc., or a combustor, etc. A seal rubber 10 is interposed between the heater 9 and the hole 8a.Furthermore, the outer peripheral edge 6.2 of the frame main body 8 is A hinge part (1) that is connected to the flange frame 2, and a clasp 11 that can be freely attached to and detached from the clasp 7 of the flange frame 2 on the opposite side.

8c and a gap 13 fitted therein are provided.

On the other hand, the tank support part that stably supports the tank part having such a structure is constructed as follows. That is, a pin 14b having a smaller diameter than other parts is attached to the upper end of the metal pipe 14a.
is fixed, and a rubber cushion 14c is attached to the lower end. At least three support legs 14 are provided (b), and these support legs 14 are spaced at the same distance from each other at the middle part and L7.
are connected to each other by a belly band 15 made of flexible abrasive material. Since the tank body 1 has tensile strength, the tank body 1 can stand on its own by providing three or more support legs 14, and the belly band 15 has an auxiliary function. It is meant to be held.

The length of the entire circumference of these belly bands 15 connected together is formed to be slightly larger than the length of the entire circumference of the tank body 1.

In addition, for the middle and lower parts of the adjacent support legs 14) L is the abdominal band 1.
6 to connect in a tazuki river shape.

When using a tank with such a configuration, first set up the three support legs 14 on the floor (on the ground in the figure), and when not using the belly straps, place the tank in the loops of the belly straps 15 and 16. Main body 1
through the holes of the three brackets 2a of the flange frame 2 through the pins 14b of the support leg 14, and fix the cap 17 to prevent it from being pulled out. In this state, the water supply port 8c of the Tekahā 8 is opened, and water is supplied from there into the ζ tank via a bow or the like. Then, the water supply is stopped when the water level in the tank reaches a level where it comes into contact with the bottom surface of the cover 8. In this case, the peripheral wall of the tank body I tends to expand outward due to water pressure, but its deformation can be restricted due to its tensile strength and support by the three support legs 14.

In addition, the vibrators 4b and 4c with the :1 connector of the heat exchanger 4 protruding from the tank body 1 are connected in series with the water supply pipe 18 leading indoors. In this state, the heater 9 is activated to heat the water to be rinsed in the tank to a predetermined temperature.

When water is supplied from the water supply pipe 18 to the heat exchanger 4 in the tank storing the hot water in this way, the raw water exchanges heat with the hot water in the tank while flowing through the heat exchange fluid passage 4a of the heat exchanger 4. The water is then heated to 1 liter and then supplied to indoor hot water demand areas. In addition, in order to improve the heat retention of this tank, the outer circumference of the tank should be, for example, 1 x 4! It is a good idea to cover the white with quilted insulation + A.

By using a tank with such a configuration, various advantages as listed in Section F can be obtained.

(1) The tank body 1 is made of flexible raw material ζ
Therefore, when not in use, it can be folded in the vertical direction as shown in Figure 1 by the chain line A t: 2 to form a convex shape, and the support legs 14 can also be bundled into three pieces, making it extremely convenient. Excellent.

(2) As the material of the tank body 1, it is possible to use a material that is excellent in corrosion resistance and tension resistance, and is low in weight and U7.

(3) Since the bottom surface of the tank body 1 is also deformable, it can be installed on uneven floors, etc., and the bottom surface directly contacts the floor surface to support the main river inside the tank on the floor surface. This eliminates the need for reinforcing plates such as Entopsy = 1.

(4) The tensile strength of the tank body and the support legs 14 suppress expansion and deformation of the tank body 1 in the outward direction, and by using at least three support legs 14 at 7.9jC, a large f of 1゛ can be achieved. Therefore, the degree of freedom of deformation of the tank body l is restricted, and the tank body l can be kept stable even if the water level fluctuates during draining.

(5) Even if a horizontal force is applied due to an earthquake, etc., the force is absorbed because the tank body 1 is not a rigid body] 1. It is difficult to overturn.

(6) As in this embodiment, when a heater serving as a vibration source (sound source) such as a combustor is attached to the frame main body 8^, the vibrations are effectively absorbed by the water immersing it, and the cover 8 The spring constant in the top direction of the frame 8 is low and the spring constant of the cover 8B and the tank body 1 are close to 0. Secondary vibration of these tank parts Effective 6. The effect of reducing noise and movement is great. In addition, a carrot is placed in the tank as a heater 9, and the water is heated by its heat.
This is particularly effective when a large vibration generating source is attached, such as when driving a vibration damper or generator connected to a second engine.

(7) When heating the water in the tank, the thermal expansion is absorbed by the water in the annular space formed below the outer rim.
The water level at the part where the heater (N) is turned off can be raised to near the bottom surface of the cover 8 from the beginning of heating, and the efficiency of heat exchange with water can be increased.

Also, since the cross-sectional shape of the tank shown in Fig. 4 is 111, it can be installed at the corner of the wall if the flange frame and the auxiliary frame are fan-shaped. You can also do it.

As explained below, according to the present invention, it is possible to obtain a tank structure that is inexpensive, has excellent corrosion resistance, light weight, and transportability, and has a large degree of freedom in installation locations and is also excellent in stability. In addition, even when a heater or the like is attached to the auxiliary valve L, -J^ section, the secondary vibration of the tank section can be suppressed by one level, resulting in a significant noise reduction.1. It is something to prepare for.
