SK41296A3 - Tank with filling and emptying device arranged on the top - Google Patents

Abstract

The tank has a gastight nozzle (8) for filling and emptying it, which is arranged on its upper side. A gastight straight filling pipe (4) projects from it, into the tank. The lower end of the pipe is rigidly connected to an internal diffuser (6) and a discharge opening. The cone angle (18) of the diffuser may range from 90 to 120 degrees. The filling and emptying equipment may be arranged on a top flange of the tank, and may be central with respect to the length of tank. There may also be a depression in the base of the tank, below the filling pipe.

Description

Technical field

The invention discloses a tank with a filling and emptying device arranged above.

The invention is suitable for tanks, in particular tank cars, in which liquids are transported. Tank wagons in which liquids are filled or emptied from above can be additionally equipped with essential parts of the inventive device.

BACKGROUND OF THE INVENTION

According to the state of the art, tanks and tank cars, especially intended for light mineral products, are generally filled from above. The throat serves as a filling opening. The filling devices are armed with either swivel filling hoses, filling arms or motorized single-tube filling devices. In this way of filling the tanks, volatile organic fuel components escape into the vicinity of the tanker, which is dangerous, harmful to the environment and is unacceptable under more recent international provisions.

Another way of filling tank wagons is by filling the filler neck located on the tank wagon down. This prior art is described, for example, in the German standard DIN 26 025 of April 1984. In this way, the above-mentioned disadvantages can be overcome. However, the refurbishment of filling equipment for this type of filling requires very high investments.

2. Summary of the Invention

It is, therefore, an object of the invention to provide an option which overcomes the shortcomings of the prior art and allows the filling and emptying of tanks from above, whereby existing filling and emptying devices can be used extensively.

This object is solved by a feature of the first claim.

It is an advantage of the inventive solution that traditional tank cars in which a throat was used for filling can be rearranged by the inventive device, so that the disadvantages of the prior art are eliminated.

According to the inventive solution, a filling tube with a gas-tight filling and emptying spout extends into the tank. At the lower end of the feed tube there is a diffuser with outlet openings, which ensures that the liquid to be filled does not impact hydrodynamically inappropriately at too high a rate on the bottom of the tank. It is advantageous to arrange the diffuser openings laterally. The free cross section of the outlet openings should be identical to the cross section of the feed tube. The shapes of the filling openings are freely selectable. Longitudinal openings are preferred from a technological point of view.

It has proved to be advantageous if the diffuser has an angle between 90 and 120 degrees. The diffuser need not be cone-shaped, for example an ellipsoid.

The filling and emptying device may be located at the top of the tank at any point, but it is offered to place the device at the neck of the tank at the throat tank. If the filling and emptying device is located elsewhere in the tank, the throat is used as a control opening. This is also achieved by removing the inventive device from the neck. The inventive device is to be fitted on the neck so as to form a gas-tight closure. It has proven to be advantageous to place the straight feed tube in the center

-3nádrže. It is to be achieved by a device that empties the tank as completely as possible, and it is advantageous if there is a depression at the bottom of the tank. It is furthermore advantageous to provide a device for aerating and venting the tank.

It is also advantageous if devices for measuring and / or regulating the filling condition are provided on the tank.

Overview of the figures in the drawing

In the following, the invention will be explained by way of example and six figures. The pictures show:

FIG. 1 a tank wagon with an inventive filling and emptying device from the throat; FIG. FIG. 4 is a cross-sectional view of the detail Y of FIG. 2, the bottom part of the filling and emptying device; FIG.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a tank wagon with a tank 1 provided with an inventive filling and emptying device whose filling tube 4 is arranged in the neck 2. The details of the neck of Figure 1 are shown in Figure 3. The neck 2 has been closed with a special neck 2 of the neck tube 4, at the upper end of which the filling and emptying spout 2 is arranged · After closing the spout 2 with a special spout cap 2, four folding screws are used

13. A diffuser is provided at the lower end of the feed tube 4

The internal shutters automatically open, forming an angle 18, the angle being adapted to the liquid to be filled and its hydrodynamic behavior. For the flow of liquid from the feed tube 4, openings 14 are provided in the feed tube. In the case shown in Figure 4, these openings 14 open longitudinal holes. In order to fill or empty the tank 1, the coupling part 16 of the filling device is rigidly connected to the filling and emptying spigot 6. Figures 5 and 6 show the coupling parts of the filling station of the filling station in different views, with a lifting eye 15 arranged to facilitate handling of the coupling part and the hose.

Figure 2 shows a tank 1 with a throat serving as a hatch and with a filling tube arranged directly next to it. In order to completely empty the tank 1, there is a recess in the bottom of the tank into which the filling tube extends. In order to check whether the evacuation process is complete, a residual quantity measuring probe 10 has been provided at this point of the tank. In addition, the tank contains a normal shut-off probe H, an overfill safety device 12 and a gas equalization port 5 · Equipped with this device, the inventive tank wagon complies with international regulations and standards.

If the tanker is to be filled, the dry clutch cap is first folded with the flame extinguisher and then the gas equalization port 5 is connected to the filling station by a hose or swivel arm. When joining the two parts, the cones of the two clutch parts thereby equalize the pressures between the tank 1 and this filling station. It is important to establish this gas equalization connection of filling or emptying first.

Then the coupling part 16 of the filling or emptying device is connected to the dry coupling of the filling and emptying spigot 5 with a hose, swivel arm or

-5filling arm. When joining both parts, the inner closing cones of the two coupling parts are automatically opened so that and can start to fill or empty the tanker. This system operates completely closed, the tank 1 is not depressurised by opening the neck lid. Also, the forced aeration and gas pressure equalization used up to now are eliminated. The neck lid does not need to open for inspection purposes. It is advantageous to install the control elements XI, 12, 10, since the control performed by the personnel can be reduced. By means of these control elements, the filling or emptying unit can be automatically released or switched off after the tank has been filled or emptied.
