Abstract

This invention relates to a tanker cargo system. The purpose of the invention is to increase the efficiency of use of the cargo tanker system. The proposed tanker cargo system contains tanks 1, a cargo pump 2, communicating with the lower part of the cargo tanks 1 by means of a suction pipe 3 with a separation tank 4 installed on it, the upper part of which is equipped with pipeline 5, which is equipped with an ejector 6 with a branch pipe 7 and is connected to the upper part of the cargo tank 1. The separation tank 4 is equipped with a liquid level regulating mechanism in the form of a float with a cone slit with a puller on its upper part, as well as a locking device With the air containing the body, with the mouth, the latter includes a cavity located in its lower part, communicated by means of a tapered hole with a separating tank 4 and with a nozzle 7 of the ejector. Radial coaxially located branches are made in the body walls, and the float's conical protrusion is designed to close the cone holes in the bottom of the body of the locking device as the float booms, with one of the radial holes in the body wall of the locking device being in communication nozzle 7 ejector. 1 hp ff, 2 ill.

Description

This invention relates to shipbuilding, 3 in particular to tanker cargo systems.

The purpose of the invention is to increase the efficiency of using the cargo system of the tanker.

On (imr. 1 schematically shows the cargo system of the tanker, a general view; in Fig. 2 - node I in flash: -. 1.

The cargo system of the tanker contains CARGO1 tanks 1, the cargo centrifugal pump 2 connected to the cargo tank by the suction pipe 3, on which the separation tank 4 is installed. The upper part of the separation tank 4 is connected to the top of the cargo tank 1 by pipe 5 on which is installed: alen ejector 6. Compressed air nozzle 7 to ejector b has a locking device 8 containing spools in the form of locking elements 9 and 10 mounted on a rod 11 connected to the float 12. On the upper part of the float 12 has a cone 13 ,, respectively Q hole.

Cargo system works as follows.

In the initial period, cargo tanks 1 and separation tank 4 are sealed with cargo. The float 12 in the separation tank is in its upper part, the cone 13 closes the opening 01, the spool 10 closes the opening for air supply to the ejector 6.

When the level falls: in cargo tanks to a critical level, vortex funnels form above the devices and air is trapped in the cargo system. The trapped air, falling into the separation 1 |: 1 tank 4, rushes to its upper part. At the same time, the liquid level in the tank drops, followed by the level of the float 12, opening otv; q q, simultaneously with the float moves down the rod 11 and moves the elements 9 and 10 of the valve, opening the access of compressed air to the ejector 6. The ejector removes the air from separation tank 4 via line 5 to the cargo tank. Thus, a quick and reliable removal of air takes place, a vacuum is created and the separation tank is filled with liquid. About

The process of removing air from the system through a separate tank occurs in automatic mode, the cargo pump 2 operates stably at full capacity.

When the cargo is pumped out of the tanks, the separation tank is emptied, the float 12 is lowered, the slide is lowered until element 9 blocks the supply of compressed air to the ejector.

Formula of Invention

Claims (2)

1. The cargo system of the tanker, containing tanks, cargo pump, communicated with the lower part of the cargo tanks through the suction pipeline through the separation tank built into it, the upper part of which (equipped with a gas pipeline, is in order to improve of use, the gas pipeline of the separation tank is equipped with an air jack with a pipe and communicated with the upper part of the cargo tank, the separate tank is equipped with a level control mechanism in it, made in the form of melting with a conical protrusion with a rod located on its upper part, as well as a locking device containing a locking organ located on the float rod, located in the housing with a cavity filled with its lower part, which is communicated through a conical hole in the bottom of the housing with a separation tank, The holes are made in the walls of this housing, one of which is in communication with a source of compressed air, the other with an ejector nozzle, and the cone-shaped protrusion of the float is designed to block the cone hole in the bottom shte housing of the locking device. 2. The system of claim 1, distinguished in that the locking member is designed as a spool, including two locking elements, the lower one of them being installed with the possibility of blocking the said radial openings of the locking body element when filling the separation tank, and the top - when it is emptied. 12 No.
