The invention relates to railway transport, in particular to self-unloading cars.

The aim of the invention is to reduce the discharge time and improve its quality.

FIG. 1 shows a tank with a discharge device and a cargo discharge, general view; in fig. 2 - the same, at the time of termination of cargo discharge or non-loading; in fig. 4 - element of the centering of the shield at the time of its transfer, side view; in fig. 3 and 5 - the same, view from the side of the loading door.

The railway tank contains a boiler 1, a loading hatch 2, an unloading hatch 3 with an outlet rail 4, an air duct 5, a cargo duct 6 with valves 7 and 8, disk-shaped shields in the form of toroids 9 and 10 with openings 11 and 12, a flexible shell 13, air-conducting chambers 14 with brackets 15, a pressure regulator 16 with couplings 17 and 18, a shield centering element 19 made in the form of a two-arm lever, the central part of which is pivotally connected to the bracket 15, the upper lever of the lever has unnor 20, and the lower arm the shoulder contains a float 21 and is connected by a flexible Zyu 22 with a shield.

The boiler contains an inlet and a socket 23 of the air duct 5 and an outlet fitting for the cargo duct 6.

The device works as follows.

When loading cargo onto tanks, the loading hatch 2 is hermetically closed and the unloading hatch 3 is opened. At the same time, through the inlet port 23 through the air duct 5 through the through hole of the coupling 17, the pressure regulator 16 and the air guide chambers 14, the compressed air is supplied press volume, rigidity and density against the walls of the boiler. In this case, the excess air is discharged by the pressure regulator 16 into the compartment between the end wall of the boiler and the shield, creating in this zone a force for longitudinal movement of the shield, which in its path in the area of the discharge hatch contacts the valve 8, allowing access of the remaining cargo in the compartment and the air mixture through the cargo line 6 and the outlet fitting into the receiving tank.

The cleaning of the boiler in the compartments from the rest of the cargo is performed automatically by the sealing toroid 10 at the moment of its longitudinal movement in the process of unloading and loading, i.e. in two stages.

When the shield moves to the discharge hatch 3, it can be tilted in the direction of motion.

When loading cargo into the compartment between the shields, it is possible to ei o tilt in the direction of the unloading hatch. To prevent this, the stop 20 of the shield centering element 19 loses contact with the surface of the boiler 1 and under the action of the buoyancy force of the float 21

the lever unfolds and transmits the angular force through the bracket 15 to the shield until its vertical orientation.

The loading is carried out with the closed discharge hatch 3 through the loading hatch 2 into the compartment between the disc-shaped shields.

Under the action of the load, the shields are dispensed by cleaning the boiler walls with toroids 10 again. As the shield moves away from the loading hatch, the valve 8 of the load line 6 closes and then the valve 7 of the cargo line 6 opens under the effect of increased pressure.

along with the air, the rest of the cargo cleared through the output pipeline shtutser. The use of the proposed tank for transporting light and dark petroleum products will reduce at least 2 times the time just under the discharge of cargo

and significantly reduce energy consumption associated with stripping the boiler of residual cargo.

Claims (1)

Invention Formula five A railway tank containing a cylindrical boiler with loading and unloading hatches, inlet and outlet fittings, with an air line and a pneumatic unloading device located inside the boiler pipelines, having a disk-shaped shield, an inflatable toroidal seal made according to the perimeter of the cross section of the boiler and the element of the centering of the shield, characterized in that, in order to reduce the time 5 unloading and improving its quality, the tank is equipped with an additional similar pneumatic unloading device located in the opposite end part of the boiler; the disc-shaped shield of each unloading device is made in the form 0 two toroids of different diameters, hermetically interconnected by a flexible shell and upper and lower air duct chambers, the upper air duct chamber is equipped with a bracket, the smaller with a toroid equipped with a pressure regulator located in its cavity on the side facing the end wall of the boiler, having connecting sleeves oriented upwards and downwards, with the coupling oriented upwards having a through hole, a toroid Large diameter 0 has two diametrically located holes, through the upper one of which passes the air duct connected to the outlet plug and upward-oriented coupling, and through the lower one - to the cargo duct connected to the lower coupling. 5 moreover, in the cargo pipeline there are holes with valves, and its end is connected to the outlet nipple, the centering element of the pin is located on the side of the loading hatch and is made in the form of a two-arm lever fixed on the bracket of the air guide chamber, while the upper arm of the lever it is in contact with the surface of the boiler, and the bottom is provided with a float and is connected to the shield with a flexible connection.
