ジ部８に固定される。(B) Prior art The heat storage tank to which the present invention is applied will be explained with reference to FIG. The through hole 2 for insertion is inserted into the side wall 3.
In addition, the tank is a 50-capacity inner tank with a top wall 5 provided with a top opening 4 for internal cleaning or piping installation services that protrudes upward, and is blow-molded in advance as a watertight container. After that, through holes and openings are formed by secondary processing. 6 is inner tank 1
This is an exterior cover that is disposed at intervals around the outer circumference of the inner tank 1 and has a flange portion 8 provided with a groove 7 that fits the top opening 4 of the inner tank 1 on its periphery, and is made of polypropylene or the like with excellent weather resistance. It is in-die extension molded using a synthetic resin material. A bonding agent 9, such as hot melt, is injected into the groove 7 in order to watertightly bond the top opening 4 of the inner tank to the flange 8 of the outer cover 6. Reference numeral 10 denotes a foamed heat insulating material which is injected between the inner tank 1 and the outer cover 6 and which integrates the inner tank and the outer cover by foaming and solidifying, and is made of, for example, hard urethane foam. Note that 11 is a lid that closes the top opening 4, and is detachably fixed to the flange portion 8 with screws 12, 12.

ンク１の内圧を高めるようにして内側タンクを補
強するようにしている。 In the heat storage tank described above, the top opening 4 of the inner tank 1 and the flange portion 8 of the outer cover 6 are bonded with a bonding agent 9.
After the foamed heat insulating material 10 is injected into the inner tank 1, it is necessary to prevent the inner tank 1 from deforming due to the foaming pressure (usually 2000 kg/m 2 ). Therefore, as shown in FIG. 2, the inner tank 1 is reinforced by inserting a jig such as a core 15 into the inner tank 1 before it is placed in the foam molds 13 and 14, or a third As shown in the figure, a rubber stopper 18 through which an air injection pipe 17 with a valve 16 is passed is attached to the top opening 4 of the inner tank 1.
While preventing the rubber stopper 18 from coming off with the foam molds 13 and 14, pressurized air is sent into the inner tank 1 from the air injection pipe 17, the valve 16 is closed, and the inner pressure of the inner tank 1 is increased to increase the inner pressure. I'm trying to reinforce the tank.

た。 However, in the former method described above, it takes a lot of effort to put in and take out jigs such as the core 15, resulting in poor productivity and high manufacturing costs, as well as causing jigs to come off or become misaligned due to vibration. However, the inner tank sometimes became partially deformed, resulting in defective products, resulting in low reliability.

た。 In addition, in the latter method, the dimensions of the top opening 4 of the inner tank 1 will vary during blow molding and when joining with the flange portion 8 of the outer cover 6.
Air leakage may occur between the top opening 4 and the rubber stopper 18. However, air was being injected into the inner tank 1 with the rubber stopper 18 housed in the foam molds 13 and 14 to prevent it from falling out, and the foam insulation was injected from the injection port 19 without checking for air leakage. Since the undiluted solution of material 10 is injected, the completed product is deformed due to insufficient internal pressure in the inner tank 1, resulting in the disadvantage that it becomes unusable.

な金属板を使用している。(E) Embodiment of the Invention An embodiment of the present invention will be described below with reference to the drawings. FIG. 4 shows the pre-process of injecting the foamed heat insulating material 10. What is different from the conventional method is that a sealing member 20 is provided in surface contact with the upper surface of the flange portion 8 of the exterior cover 6 over its entire circumference. At the same time, the sealing jig 21 for shielding the top opening 4 of the inner tank 1 is inserted with the screws 22 and the sealing member 20 interposed.
It is firmly fixed at 22. An air injection device (not shown) and an air injection pipe 24 with a removable valve 23 are attached to the enclosure jig 21, and the valve 23 has a mounting port 25 for a pressure measurement gauge (not shown). It is provided. The seal member 20 is made of a closed-cell foam rubber material (for example, chloropylene rubber or ethylene propylene rubber) that has little permanent compression strain. Further, the sealing member 21 is made of a metal plate having a relatively large thickness and capable of compressing the sealing member 20.

合でもこれを吸収できることになる。 In this embodiment, as described above, in the pre-injection step of injecting the foamed heat insulating material 10, the sealing fitting 21 is firmly fixed to the flange portion 8 of the exterior cover 6 with the sealing member 20 interposed therebetween. 20 comes into close contact with the flange portion 8 and the inner wall surface of the sealing fitting 21 in a compressed state, and the inside of the inner tank 1 is sealed. Since the sealing member 20 is in surface contact with the flange portion 8 over the entire circumference, even if there is a dimensional variation in the top opening 4 of the inner tank 1, this can be absorbed.

The pressure of air sealed is preferably 400 to 500 mmAg, and the valve 23
Attach a pressure measuring gauge to adjust the amount of air enclosed. After filling the air, valve 23

The presence or absence of air leaks can be determined. If air leakage is confirmed, it may be due to a poor connection between the top opening 4 and the flange 8, or due to the sealing jig 21.
It was thought that the foam insulation material 1 was not fixed properly, so we removed it from the production line, took necessary measures, and removed the foam insulation material 1.

アー漏れが少なくなる。 The bonding agent 9 is generally a hot melt made of an olefin resin as a main component to which tackifiers (aliphatic resins), paraffin waxes, fillers, etc. are added. Reinforce the inner tank 1 using pressurized air,
When injecting the foamed heat insulating material 10, it is preferable to use a hot melt with a reduced amount of the main component and a corresponding amount (several percent) of special synthetic rubber such as SBR (styrene butadiene rubber). This type of hotmelt has increased stickiness, flexibility, and elasticity, which prevents it from cracking due to pressurized air.
Air leakage due to poor connection between the top opening 4 and the flange 8 is reduced.

deformation can be reliably prevented, and there is almost no possibility that the finished product will be defective. In addition, compared to the conventional method of inserting a jig such as a core, it requires significantly less manpower, promotes labor saving and automation, and is excellent in productivity. Furthermore, the screw holes created to fix the sealing jig 21 are screws 12 for fixing the lid 11,
It can be used as is as 12 holes.

ある。(F) Effects of the Invention As explained above, the present invention provides a method for sealing the top surface of the inner tank using a sealing jig and a sealing member before injecting the foam insulation material between the inner tank and the outer cover. By sealing the opening and injecting the required amount of pressurized air in advance, we have made it possible to check for air leaks from the inner tank, making it easy and reliable to prevent the inner tank from deforming due to the foaming pressure of the foam insulation material. It can be prevented, saves labor, has excellent productivity, and is economical because finished products are not wasted.
