Description

The invention relates to a device for loading light petroleum products into road and rail tank cars and can be used when shipping fuel and lubricants at stationary and field bases and warehouses, as well as at enterprises for the production of petroleum products.

When reviewing the technical literature, a number of constructive solutions related to the indicated problems were identified.

Known is a bulkhead riser containing a vertical stand, movable links articulated with each other, one of which has a counterweight, a "swivel" in the form of an knee equipped with two mutually perpendicular hinges, an air valve, an induction level sensor and a position sensor (utility model patent RU 38748 , class B67D 5/00, publ. 10.07.2004, bul. No. 19).

There is also known a system for filling petroleum products containing a vertical stand, a swivel pipe, a filling pipe on which a limit level sensor and a drip tray, a counterweight, a hydraulic cylinder with an arm and a control unit, a swivel pipe arm, a swivel pipe tilt sensor, a ground circuit control unit, a spark gap are installed electrostatic charge, remote control, liquid meter, limit level sensor (patent for invention RU 2258668, class B67D 5/00, publ. 20.08.2005, bull. No. 23).

The main disadvantages of these devices are:

- the complexity of the mechanism for stopping the supply of oil to the transport tank after reaching the maximum permissible level of its filling, which consists in the need to use a sensor for this, which generates a signal to stop filling when the column of oil in the tank reaches the maximum level, a signal transmission line to stop filling and an actuator to stop filling the transport tank;

- the inability to exclude an excessive amount of oil product from entering the transport tank after reaching the maximum filling level of the tank, due to the delay from the moment of actuation of the actuator to stop filling the transport tank until the end of the expiration of the oil product from the filling tip.

The closest to the claimed invention is a device for filling petroleum products into a transport tank, containing a filling nozzle, a pipeline system, a counterweight, a flexible steam outlet, a sealing cap of the filling nozzle, a device ready for filling sensor, a level sensor, a check valve installed in the filling nozzle (patent for invention RU 2532151, class B67D 7/04, publ. 27.10.2014, bull. No. 10).

The main disadvantage of this device is the complexity of the mechanism for stopping the supply of oil to the transport tank after reaching the maximum permissible level of its filling, which consists in the need to use a sensor for this, which generates a signal to stop filling when the column of oil in the tank reaches the maximum level, a signal transmission line to stop filling and an actuator for stopping the filling of the transport tank.

The problem to be solved in the invention is to eliminate these disadvantages by developing the design of the filling tip of the riser for the top loading of oil products into the transport tank, which ensures the rapid termination of the supply of oil to the transport tank when the column of oil in the tank reaches the maximum permissible level.

The technical result of the invention consists in increasing the efficiency and reliability of stopping the flow of oil into the transport tank after reaching the maximum level of its filling and eliminating the loss of oil.

The problem is solved, and the technical result is achieved as a result of the fact that, according to the invention, the filling tip of the riser for the upper filling of oil products into the transport tank contains a pipe with a plug installed at its lower end and outlet openings made in the lower part of the pipe along its circumference on equal distances from each other, a ring-shaped float installed in the upper part of the pipe and connected by rods with a locking ring to overlap the cross-sections of the outlet openings when the float reaches the lifting height corresponding to the maximum level of filling the transport tank with oil product, and a locking ring that limits the lifting height of the float and fixing its position when reaching the maximum lift height.

The invention is illustrated in FIG. 1 and 2.

FIG. 1 schematically shows a riser filling tip for top loading of oil products into a transport tank in the filling phase.

FIG. 2 schematically shows a riser filling tip for top loading of oil products into a transport tank at the end of its filling phase.

FIG. fig. 1 and 2, the following designations are used:

1 - pipe;

2 - plug;

3 - outlet;

4 - locking ring;

5 - float;

6 - thrust;

7 - retaining ring.

The filling tip of the riser for the top loading of oil products into the transport tank works as follows.

In the lower part of the pipe 1, along its circumference at equal distances from each other, outlet openings 3 are made at a distance from the lower end of the pipe 1, approximately equal to 1.5 of the diameter of the outlet 3. At the lower end of the pipe 1, a plug 2 with a radius exceeding pipe radius 1 to the thickness of the locking ring 4.

In the lower part of the pipe 1, a locking ring 4 with a width approximately equal to 1.4 of the diameter of the outlet 3 is installed with the ability to move along its outer surface in the axial direction.

In the upper part of the pipe 1, a float 5 is installed, made in the form of a ring, which is connected by rods 6 located at an equal distance from each other with a locking ring 4. On the upper part of the pipe 1, above the float 5, a locking ring 7 is fixed, made with the possibility of fixing the float 5, ensuring the distance from the float 5 at the lower extreme position of the locking ring 4, approximately equal to 1.4 of the diameter of the outlet 3. The upper part of the pipe 1 is connected to the supply pipe of the riser for the upper loading of oil products (not shown).

The pipe 1 in a vertical position is fixed on the hatch of the transport tank neck so that the lower part of the retaining ring 7 is at the level of the maximum permissible height of the column of oil for this transport tank, and a pump (not shown) is turned on for loading the oil product. The internal cavity of the pipe 1, bounded in its lower part by the plug 2, is filled with the oil product, and then through the outlet openings 3 it is provided to enter the internal cavity of the transport tank.

The float 5, upon reaching the level of the liquid column in the transport tank, at which there is contact between them, rising along the pipe 1, by means of the rods 6 moves the locking ring 4, which, as it rises, gradually overlaps the cross-sections of the outlet openings 3. The oil product pressure, which gradually increases in the internal the cavity of the pipe 1, bounded by the plug 2, acts on the sensor installed on the supply pipeline of the riser for the upper loading of oil products (not shown), from which a signal is sent to reduce the speed of the pump impeller (not shown). After raising the float 5 to a level at which it comes into contact with the retaining ring 7, which fixes the float 5 in this position, the pressure of the oil product in the pipe 1 reaches its maximum value, acts on the sensor installed on the supply pipe of the riser for the top loading of oil products, from which the signal is sent to turn off (stop) the pump.

The pipe 1 is removed from the hatch of the transport tank neck, placed in a special container for draining the residual oil product (not shown) and the float 5 is disconnected from the locking ring 7. The locking ring 4, dropping under the influence of its own gravity and the gravity forces of the float 5 and rods 6, opens the cross-section of the outlet openings 3 through which the residual oil product is drained.

Thus, as a result of the implementation of the proposed technical solution due to the development of the design of the filling tip of the riser for the top loading of oil products into the transport tank, an increase in the efficiency and reliability of stopping the supply of oil to the transport tank is provided when the column of oil in the tank reaches the maximum permissible level and the elimination of losses of oil product.
