Abstract

The plug for pressure emptying of drums solves the emptying of drums with liquids using compressed gas. The drum plug is equipped with two pipes passing through the plug, with the emptying pipe being inserted all the way to the bottom of the drum. The gas pipe passes through the emptying pipe, where it is provided with an opening for the gas outlet. Shut-off valves are installed on both pipes. By connecting the compressed gas pipe and the transport pipe, after opening the valves, the liquid is expelled from the drum, which can be interrupted at will. The liquid transport height is partially increased by the opening for the gas outlet. The plugs can be used for emptying drums with liquids in operations where compressed air, inert gas or a vacuum distribution system is available.

Description

The invention solves a plug for pressure emptying of drums filled with liquids by gas pressure with the possibility of liquid dosing, while avoiding vapor dispersion and staining of the drum.

The emptying of the drums is carried out in the following ways: pouring directly from the opening by turning the drum, draining using the emptying drum closure according to the author's certificate 211 453, pumping by hand or electric pump, vacuuming by vacuum. The disadvantages of these emptying methods are as follows. Pouring liquid directly from the drum opening causes uncontrolled staining of the drum and funnel. When discharging according to author's certificate 211 453, the barrel must be turned over and placed on the barrel pallet after screwing on the cap. In all of the above-mentioned emptying processes, liquid vapors are dispersed in the vicinity of the drum, which is undesirable especially in the case of hygienically defective and flammable liquids.

The aforementioned drawbacks are overcome by the pressure emptying plug of the drums of the invention. It is an object of the present invention to provide a raw plug for connecting the drum to the conveying line and connecting the pressurized gas to thereby empty the drum without contact of the liquid and its vapors with the environment. The drum stopper is equipped with two penetrating pipes, which are equipped with shut-off valves. The discharge pipe obliquely intersects the gas pipe provided with a gas outlet opening.

By using the pressure emptying of the drum according to the invention, it is ensured that the vapor dispersion of the liquid into the environment is prevented, or the spillage of the poured drum or the environment is contaminated. The barrel remains standing on the floor with the opening facing upwards, so the possibility of dripping is eliminated. The liquid can be dosed and transported to the higher locations, according to the permissible pressure load of the drum.

The attached drawing shows a vertical section of a plug for pressure emptying of a drum.

The stopper for pressure emptying of the drum consists of the drum stopper 1, through which a tightly connected emptying pipe 2 of length L, which corresponds to the diameter of the drum and ends above the bottom. The gas pipe 3, which terminates below the barrel stopper 1, is closely connected to the barrel stopper. terminated with B, 7 terminals for connecting the fitting. When the external fluid and pressure gas lines are connected to the plug according to the invention screwed into the barrel opening and after the valves are subsequently opened, the fluid is forced out of the barrel. After emptying the drum, which can also be dosed, the valves are closed and the external piping is disconnected so that the vapors of liquid remain in the drum until controlled discharge at the selected location.

The drum emptying plugs can be used to transport liquids from drums wherever compressed air, inert gas is available, or inert gas cylinders are available and lower head heights are required. These are limited by the permissible barrel hooking and the specific gravity of the liquid. By providing a gas outlet opening X of a suitable cross-section into the gas tube, the delivery head of the medium increases in proportion to the specific gravity. The plugs according to the invention can also be used for suction of liquid from a drum by means of vacuum, the gas pipe serving as an aeration.
