Abstract

This invention relates to cargo tanker systems. The purpose of the invention is to simplify the design, increase the compactness and efficiency of operation of the cargo system of the bulk vessel. The proposed cargo tank loading system contains a cargo tank 1 in which a vacuum-injection tank 2 is placed, the upper part of which is equipped with a gas-jet ejector 3, and the lower part with a receiving pipe 4 with clinker 5, the drive 6 of which is brought to the deck of the ship. The upper part of the tank 2 is connected with two lines to the compressed air pipeline 7. One line passes through the suction nozzle with valve 8, the ejector 3 and the bypass valve 9, the second line through the compressed air valve 10 and the nozzle. The ejector 3 through the pipe 11 is connected to the cargo tank 1. Inside the tank 2 is placed the pipeline 12 issue of cargo, equipped with a ram 13 and connected through the valve 14 with the cargo pipe 15. The cargo tank 1 is equipped with an atmospheric pipe 16. 1 Il. W (O

3, For this, valve 9 for supplying compressed air to the gas ejector is refused. As a result, a vacuum is created and the tank 2 is filled with cargo. To transfer the liquid cargo to the vessel or to the coastal receiving tank, they close the filling system of the vessel of the type bar-IQ valve 8 suction and valve 9, and lead or lighter.

in particular to cargo tanker cargo systems.

The purpose of the invention is to simplify the design and increase the compactness and I efficiency of operation of the cargo system of the bulk vessel.

The drawing shows a diagram of a cargo-carrying system for a tanker containing a cargo tank 1, in which i is vertically placed a vacuum-pressure tank 2, the upper part of which protrudes above the cargo tank 1 and is equipped with a gas turbine ejector 3 the suction inlet 4 with the blade 5, the drive 6 of which is brought onto the deck of the vessel. The vacuum tank 2 can also be located outside the cargo i tank 1. The upper part of the vacuum pressure tank 1 is communicated to two : paths with pipeline 7 compressed air. One path passes through the suction nozzle with valve 8, gas jet, ejector 3, bypass valve 14 and 10 open. Compressed air enters the vacuum-injection tank 2 through valve 10 and is displaced

If the liquid cargo, which through the snoring 13, the pipeline 12, the cargo, the valve 14, the cargo deck 15 and the flexible hose 17 enters the receiving tank. When loading a load

The 2Q vacuum pump tank 2 operates as a pressure vessel.

After the cargo is displaced from the vacuum-injection tank 2, the valves 10, 14 overlap, and the valves 5, 8, 9

25 is opened and the vacuum tank is refilled.

To speed up the unloading process, two vacuum-pressure tanks 2 can be installed in the cargo tank.

Claims (2)

The displacement of cargo, the other, is filled with cargo from tank 1. In order to prevent environmental pollution, after the bunkering of the vessel is completed, cargo is sucked out of the flexible hose and cargo pipeline into the vacuum-compression cistern. To do this, valves 5 and 10 are closed, valves 8, 9, 14 are opened, in a vacuum-inlet-tank 40 a tank 2 is created, which is rarefied. and cargo remains are merged into it. Shadow Formula Cargo system of a bulk vessel supplied with a source of compressed air. The gas-jet ejector 3 is connected via a pipe 11 to the cargo tank 1. Inside the vacuum-discharge tank 2 there is a cargo pipeline 12, equipped with a ram 13 and connected through the valve 14 to the cargo pipeline 15. For communication with the atmosphere, the cargo tank 1 is equipped with an air pipe 16. The pipeline 15 and 7 are equipped with flexible hoses 17 and 18. I The system works as follows. Deck pipe pipeline 15 with a flexible hose 17 is connected to the tank of the vessel to be hoisted or from the shore, which is in communication with the atmospheric receiving device, and the cargo tank, the vacuum cistemporod 7 of compressed air - with the flexible hose 18 and the compressed air system bunkable vessel. With a high level of cargo in tank 1, the clinker 5 of valve 8 is opened and valves 10 and 9 are closed. As a result, the liquid cargo flows by gravity into the vacuum-pressure tank 2. The air displaced by the load escapes through the valve 8, the flow-through part of the gas-jet ejector 3 and the port 11. When the cargo level in the tank 1 is low, filling the vacuum-pressure tank takes place 14 and 10 is opened. Compressed air enters the vacuum-injection tank 2 through valve 10 and is displaced liquid cargo, which through the snoring 13, the pipeline 12 loads, the valve 14, the deck cargo pipeline 15 and the flexible sleeve 17 enters the receiving tank. When loading a load the vacuum-pressure tank 2 works like a pressure vessel. After the cargo is displaced from the vacuum-injection tank 2, the valves 10, 14 overlap, and the valves 5, 8, 9 open and fill the vacuum tank once again. To speed up the unloading process, two vacuum-pressure tanks 2 can be installed in the cargo tank. well, the lower part of which is communicated with this tank by means of a tailpipe with a blade, its upper the part is equipped with pneumatic lines with valves, as well as a cargo delivery line, characterized in that, in order to simplify the design, increase the compactness and efficiency of operation, the vacuum tank is equipped with a gas-jet ejector installed on one of its pneumatic lines and an additional valve and is placed inside the cargo 313699834 the lower part of the compressed air, and the pipeline is laid out at the bottom of the latter, the upper part of the cargo is mounted inside the vacuum a part is above its level and a stern tank; moreover, a gas-jet ejector by means of the said pneumatic guide located on the pneumatic line between the sieves and valves with the main source and additional valves.
