SU1508031A1 - Closure for pneumatic-discharge transport tank port - Google Patents

Abstract

The invention relates to locking bodies of transport tanks of bunker cars with pressure relief from compressed air. The purpose of the invention is to increase the reliability, safety of unloading and reduce the consumption of compressed air. The hatch of the hatch contains a cover 7 hinged on the container 4, a screw clip 8 of the cover, an internal cover 1 for engagement with the seal 9, an elastic cover 2 with openings for supplying compressed air to it. The cover 1 is moved relative to the guides 5 by means of the clips 6. The guides are fixed on the container walls at the base of the loading door and are provided with a tray 3 for placing an elastic shell thereon. Holes in the pan are aligned with holes in the shell. The holes have a different diameter to create an overpressure in the casing compared to the pressure inside the container, with larger diameter openings connected to the pipe 10 for supplying compressed air to the inside of the casing, and smaller diameter openings 11 are connected to the cavity of the container. 3 il.

Description

The invention relates to railway transport, in particular to shut-off bodies of transport tanks of bunker cars with unloading under pressure of compressed air.

The purpose of the invention is to increase the reliability, safety of unloading and reduce the consumption of compressed air.

Supplying the device with an internal lid for interacting with the gasket on the opening of the hatch increases the reliability of the shutter and, consequently, increases the safety of unloading operations during unloading by pneumatic method, since even when the lid is opened the hatch is under compressed air pressure. In addition, the seal placed inside the tank is not subject to contamination and can provide the most complete sealing of the tank hatch, and therefore will reduce the flow of compressed air used during unloading.

Supplying the device guides the pallet to interact with the inner kryppka attached to the walls of the container at the base of the hatch, placing the elastic sheath between the pallet and the inner kryinka works

Since the elastic shell is inside the tank under pressure, to close the hatch with an internal latch, it is necessary to create an overpressure inside the shell compared to the pressure in the tank. This is achieved by making holes of different diameters in the pan, with the holes of a larger diameter communicating with a source of compressed air, and the holes of a smaller diameter with the cavity of the container.

FIG. 1 shows the shutter in position when loading the container; in fig. 2 shows section A-A in FIG. one; in fig. 3 - shutter in the unloading position.

The hatch of the transport container hatch consists of an inner lid 1 of spherical shape, which with its inner surface is attached to an elastic sheath 2 supported on a pallet 3, which is supported under the hatch of the tank 4 on four cylindrical guide rods x 5, which are moved in cages 6 inner lid 1, center mounted on the side of the tank 7 and screw clamp 8, at 1} 1 and 9, installed in the new hatch, socket 10

for supplying compressed air to the shell

at unloading, calibrated hole 1

(diameter of gauge hole is smaller

the diameter of the compressed air supply opening defined by the nozzle 0, which makes it possible to maintain excess pressure in the cavity of the elastic shell 2). The shutter operation is as follows.

When the container is loaded (Fig. 1) 7 is open, the inner cover 1 is in the lower position, no compressed air is supplied to the container. The load is loaded by gravity through the throat of the tank 4, the convex (spherical) surface of the inner lid flows over. After filling the tank 4, the hatch is closed by the lid 7 fixed with a screw clip 8. When unloaded, the tank 4 is connected to a stationary source

compressed air, and the pipe 10 in the elastic sheath 2 p. enters the compressed air.

Due to the presence of a calibrated orifice 11, the diameter of which is smaller than the CONDITIONAL passage of the nozzle 10, an overpressure is created in the cavity of the shell 2. When straightened, the casing feeds the inner crink 1 to the bottom of the hatch. Kripka 1, pressing against the seal 9, seals reliably; 1yuk of the transport container. The inner door 1 locks the hatch until pressure is maintained in the vessel, i.e., until the vessel is fully loaded.
