Safety tank with plastic inner cover _i

The invention relates to a safety tank with a plastic inner shell, in the form of a rectangular container or any "any shape in which a plastic shell is inserted, wherein A partial cover can be used for rectangular containers which is applied to the container by clamping rings or by a vacuum. ·· ''

The invention consists in that a rectangular container, possibly a pressure vessel without a " Stiffening system or with ^ a removable stiffening system to accommodate heating oil or other corrosive liquids with a completely coverable inner plastic cover is, wherein a cavity is provided between the container wall and the inner shell and the inner shell is airtight at the entrance dome with the help of a clamping ring and

a clamping screw is attached.

According to the invention you can also proceed so that on one side of the container, between the container and the 'inner shell, a guide tube with a Iieck display clock is provided, being at the lower end a float is installed in the guide tube or an electronic leak warning device with an oil / water probe can be used.

V

A construction according to the invention provides that are provided for 'fixing the inner shell to the container clamping pieces, consisting of a clamping body and a conical clamping sleeve, the clamping body is screwed a £ the tank wall.

Finally, you can proceed according to the invention so that A vacuum tester can be attached to the guide tube to check for leaks.

There are ordinances for the protection of the groundwater supplies during the storage of heating oil, which are for the security the inner liner of the container with control devices to write. The heating oil or another aggressive liquid stored in the tanks leads to, unprotected containers caused by corrosion to considerable damage to the tank walls, 'in particular on the tank bottoms, which * creates the risk of drinking water contamination. It is known such containers to protect the inside with a plastic coating, but the inside walls of the tank must be used for this Removed rust, rolled skins or other residues through a special pre-treatment of the material There is also no display option

with plastic-coated containers, so that unobserved Corrosion can occur and the container becomes defective.

There are also known containers in round and also angular shape, which are equipped with plastic inner shells are, with round containers special tubular or profile-like stiffening rings the inner shell press against the container wall. It is also known to cause the plastic inner shell to be of concern achieve that a yakuum is maintained between the inner shell and the container wall, which is very important is expensive. ">>

In the case of rectangular containers, the installation of inner sleeves is necessary very difficult- especially by not standardized sizes of these containers, as well as the solid stiffening material in the container. It is known to provide partial shells in such containers, but which do not cover the upper wall of the tank. If the tank is overfilled with heating oil or the like or with a pressure filling there is a considerable risk that between the container wall and the inner shell the oil flows and there is no longer any protection.

The invention addresses these disadvantages to be avoided by providing a plastic inner sleeve for a rectangular container, all of which Protects parts of the tank against contact with heating oil or other corrosive liquids and made possible by the special type of attachment easy replacement of the defective inner shell and a

Carrying out the corresponding repairs, which are not time-consuming and do not incur high costs.

Further features of the invention emerge from the following description of an exemplary embodiment in FIG Connection with the drawing and the claims.

It show, in schematic sketches,

Figure 1 shows a section through the safety tank according to the invention and

Figure 2 shows a section through a clamping piece with clamped film.

■ 'ι

In Figure 1, a rectangular 'container 2 is shown, in which an inner shell Ί is installed. The inner shell 1 is on the entry dome 10 by a clamping ring and a clamping screw 4 attached airtight so that in the event of overflow or pressure filling of the container, no liquid between the tank wall and the inner shell can get. A cavity 5 is provided between the tank wall 2 and the inner shell. On the right side of the container 2 is arranged between the inner wall of the tank and the inner shell 1. A guide tube 7, on the upper end a leak indicator 8 is attached and a float 6 is provided at its lower end. Instead of the float 6, an oil-water probe can also be used and instead of the leak indicator clock 8, an electronic leak warning device can be used. Sobal'd oil in the When cavity 5 arrives, the float 6 is pushed upwards and its change is shown on the leakage indicator 8 displayed. The leak indicator 8 including the float 6 must be exchanged for a vacuum tester, so die.Dichtheit des. Container 2 and the inner shell

to consider. If a leak detector with an oil-water probe If the inner shell is defective, the oil reaches the oil-water probe and dissolves electronically outputs a leak indicator with an acoustic and optical signal.

The inner shell 1 is suspended from clamping pieces 9 (FIG. 2) on the upper container wall and can, if necessary, be can also be attached to other tank walls. The clamping pieces 9 consist of a clamping body 12 with a hole at any point in the. .Tank wall can be screwed tight and a conical Sleeve 11, which the tank inner shell or the Üolienmaterial of the tank inner shell by sliding it over clamped over the clamping elements12.
