Description

one

The invention relates to the technique of loading and discharging liquids into transport tanks and can be used at the points of loading and unloading of railway and automobile tanks.

The purpose of the invention is to increase reliability and ease of operation.

FIG. 1 schematically shows a device for top filling or draining liquids from transport tanks} in FIG. 2 is a section A-A in FIG. 1i in FIG. 3 shows the node I in FIG. one; in fig. 4 shows a variant of the device with a stripping pipe in fig. 5 is a section BB in FIG. 4. A device for the top loading or draining of transport tanks consists of a body 1, a drain and filling pipe 2, made in the upper part with a U-shaped bend 3, inside which is placed a cross 4 with a spherical stop 5. At the end of the U-shaped bend 3 a sylph 6 is installed, to the end of which is attached a shell 7 with an end seal 8 and a crosspiece 9 having a support point 10. A movable compensating sleeve tic mounted on it 12o is mounted along the bottom end of the drain-filling pipe 2 along the outside s The camshaft rail 13 and the support bar 14 supported on the roller 15 are fixed. On the casing 1 the stops 16 and the drive mechanism 17 are fastened. The casing 1 is attached to the receiving pipe 18, equipped with the connecting flange 19 facing up. Under the flange 19 on the distribution pipe 18 A hydraulic control valve 20 is installed to communicate the internal cavity of the discharge pipe 18 with the atmosphere through a pipe 21 extended above the upper level of the П-o different bend 3 "

The device can be equipped with an additional cleaning line consisting of a cleaning pipe 22, located inside the drain-filling pipe 2, equipped at the bottom with a compensating tip 23 and having a U-shaped bend 24, ending with elements identical to 4, 6, 7, 8 about |

of different elbows. In this case, the outlet pipe 25 is fixed to the I flange 19 from the bottom.

The device works as follows 5 times.

By means of a gear 17, using the toothed rack 13, the drain-and-bulk pipe 2 is lowered into the transport container, while the roller 15 ensures that the transmission teeth are sticking. The pipe 2 is lowered to touch the shell 7 with the flange 19, while compressing the bellows 6 and the effect of the spherical stop 5 through the pin 10

15 on the shell 7, the latter is installed without distortions, which ensures the sealing of the loading line; the discharge of the product. With this, the end of the compensating sleeve 11 bottom

20 and in the process of changing its draft, it tracks the change in the position of the bottom.

When filling, the liquid passes through the pipeline 18 and the drain 25 but the filling pipe 2 enters the transport tank. At the end of the filling, the pressure in the discharge and filling pipe 2 is equalized to atmospheric using valve 20 and then the product is pumped out of the receiving distribution pipe 18. After releasing the U-shaped elbow 3 from the product, turn on the mechanisms of iodine 17 for lifting drain-bulk

j of the pipe 2. When the disk 12 comes into contact with the stops 16, the sleeve 11 moves to its extreme position. To protect the open cavities of the discharge distribution pipe 18 and the drain pipe 2 during lifting from the ingress of dust and moisture, an elastic cover (not shown) is provided.

When the liquid from the transport tank is drained (the preparatory operations of the device are the same as when filling. After the level of the pumped liquid is lowered to such an extent that air begins to flow into the drain pipe 2, the drain stops.

The stripping of the bottom of the liquid can be done through a scrubber. The tightness of the U-shaped joint of the elbow 24 and the outlet pipe 25 is ensured similarly to the connection of the transfer-dispensing pipeline 18 and the U-shaped elbow 3,

Thus, the optimal conditions for the sealing elements, the possibility of automated cleaning of residues, simplicity of design

 Operation without complicated and bulky telescopic systems increases reliability and ease of operation. The device is fire and explosion safe, 5 ensures operation without spills, does not pollute the environment, is fully automated.
