Description

Disc gas container. With the disk gas tanks of the known types A sealing body slides like a piston on the inner wall of the container and acts as a result of the frictional forces caused by the movement, they both wear out heavily on the container jacket as well as on the sealant.

According to the invention, a disk gas container is built in which only low frictional forces occur when moving, so that neither the container wall nor is the sealant exposed to frictional wear. It will therefore it is also possible to use a less hard building material than iron for the container wall use and thus more economical to build.

According to Fig. I, the disk gas container consists of a jacket a, the apart from iron also made of stone (brick or any shaped stone), concrete or Reinforced concrete can be run.

If it is executed in stone, concrete or reinforced concrete, the necessary Gas impermeability achieved in a known manner by an inner thin sheet metal skin However, their careful installation encounters certain difficulties. It is therefore better to achieve the gas impermeability in such a way that one a melt product (asphalt putty or the like) as a special interior. Layer applies. The applied layer also serves to level out unevenness. Even the appropriate use of fluorates (in conjunction with Torkret) makes the. porous walls gas-tight. The cover plate consists of an upper part c and a lower part d; the latter is as a ring basin (filling: glycerine, water o. The like.) formed, in which the upper part c is immersed by means of several ring jackets e. Instead of a single basin, several narrow ring basins can be arranged will.

The two disc parts, which are completely "equal in weight", can move telescopically and hook according to the height of the ring jacket e in the end positions. "Equal weight" is understood here to mean that both Panes the weight per square meter of gas attack surface is approximately the same, so that both disks float at the same gas pressure.

Both disc parts c and d can stand alone against the The container wall can be sealed, and each seal can be lifted for itself will; the disc part concerned is then movable.

The procedure for filling the container with gas is assumed as follows: the lower disk part d is sealed against the wall, while the upper disk part c it is not. If gas flows in through the feed line f, the upper pane becomes part c lifted by the gas pressure as far as the telescope allows. The disc part d remains at rest because of the frictional forces due to the seal against the wall would have to be overcome, for which, however, the gas pressure is not sufficient. Has the disc part c reaches the end position, the seal switches over automatically the two disc parts, such that now the upper fixed disc part c is sealed against the wall, while the lower disk part d is freely movable will. The gas pressure therefore now lifts the disk part d. The telescopic disc climbs so to a certain extent high up on the inner container wall. Is the gas consumption in If the network is larger than the supply of fresh gas, the pane climbs down again. Within the height of the telescope, the movable disc part can respond to gas pressure fluctuations adapt directly without having to switch the seals.

In Fig. 2 is a cross-section through a suitable sealing construction shown between disk and container wall. The seal known per se consists of a rubber ring g and a pneumatic ring h. Will be in the air ring h compressed air or any gas is introduced, the ring h swells and presses the rubber ring g firmly against the inner wall b and seals the disc.

If the compressed air is blown off, the rubber ring is shortened and removed again from the inner wall. In the latter case, the disc is movable.

The compressed air is in a container i, which can be hung on the roof structure k , and is guided by means of a flexible cable L to the telescopic disc. The supply of compressed air into the container i takes place by means of a gas pipe m and is pressed up by a pump set up outside the gas container. The rings g, h are carried along by drivers x when the seal-free disk part moves. In order to switch over the supply of compressed air to the two air rings h of the disc parts c and d, a four-way valve o (Fig. 3), known per se, is installed, which - when turned by go ° the compressed air line l to the supply line hl of the air ring of the lower pane and at the same time the supply line h2 of the air ring of the upper pane to a line p leading to the outside. Another 90 ° rotation interchanges the two lines. The rotation of the cock o can be brought about automatically in the end positions of the respective movable disc part.

In order to achieve a straight guidance of the disc with no lateral Guide rollers attack the inside wall of the container and eat away damaging grooves there, chains q are arranged, which run over sprockets r (Fig. t). The sprockets are expediently coupled to one another in order to lead or lag behind on one side to prevent.

In Fig.q. is the plan of the one suspended from the roof structure Sprockets r shown with an arrangement of four chains.

The axes s of the chain wheels y are up to the common point of intersection extended and there wear bevel gears t. The movement of a sprocket causes thus a corresponding movement of all other sprockets. This becomes a precise unrolling and rolling up of the chains q and thus the horizontal guidance of the pulley c scored. The chains q run in a known manner outside the container in a special way Chain shafts u and enter the container below with a liquid seal, run over wheels v and attack the disc from below.

The straight-line guide of the lower disc member carried by d Fig. W z by means of racks which are fixed to the disc portion d and x scroll gears are located at the top disk part c. Two opposing toothed wheels x are located on a common axis y, whereby the straight guidance of the disk part d is secured with respect to c, since with this arrangement a one-sided lead or lag is excluded.
