Description

The invention relates to a device for loading transport tanks from stationary tanks with various liquids. Closed filling can be used when filling aggressive products, when it is necessary to reduce the vapor from the product being pumped into the atmosphere.

A well-known riser containing pivotally connected pipe links, a balancing mechanism, a filler pipe with a support flange, a grip and a latch mounted on it, a pneumatic level sensor and a shut-off valve connected to it, while a support plate is parallel to the support flange (SU 1027090 A, 07/07/1983).

The disadvantage of this device is the lack of sealing of the neck of the tank due to possible distortions of the support flange with respect to the neck, as well as the complexity of the design and, as a consequence, low reliability.

The closest invention in its technical essence to the described invention is a closed filling containing a filling riser made of movable pipes with elbows connected to each other and the root flange by hermetic hinges, providing the possibility of movement in all directions of the filling pipe with a sealing lid carrying a sealing element and emergency level switch and vapor exhaust hose (SU 144193 A, 1962).

The disadvantage of this device is the inability to use a sealing cover for the necks of tanks of various sizes.

The objective of the invention is the provision of sealing the neck of tanks of various sizes.

The problem is solved due to the fact that in a closed bulk tank containing a riser made of movable pipes with elbows connected to each other and the root flange by hermetic hinges, providing the possibility of movement in all directions of the bulk pipe with a sealing lid carrying a sealing element and an emergency signaling device the level, and the vapor exhaust hose, while it is equipped with a protective cylinder for the emergency level switch mounted on the inside of the lid, parallel to the filling pipe, and a locking mechanism mounted on the outer side of the cap, wherein the sealing cap is made in the form of a disc with a fitting for attaching a vapor exhaust hose and connected to the disc with the possibility of rotation relative to the latter by means of rollers of the overlay ring with grooves made on the outer cylindrical surface of the ring and making it possible installation and fastening of the sealing cover to the necks of tanks of various sizes and fixing the lid on the neck with fasteners of the cyst neck itself us.

Figure 3 shows a section along aa of the sealing cap in figure 2.

Figure 4 shows a section along BB of the sealing cap in figure 2.

Figure 5 shows the location In the sealing cover in figure 2.

The closed bulk contains a bulk riser made of movable pipes 1 with elbows, one of which has a counterweight 2, interconnected with the root flange 3 and sealed hinges 4, providing the ability to move in all directions of the bulk pipe 5 with a sealing cap 6 carrying a sealing element 7 and an alarm (not shown) of an emergency level, and a vapor exhaust hose 8. At the same time, the closed filling is equipped with a protective cylinder 9 of the emergency level switch and its locking mechanism 10 mounted on the outside of the cover 6 mounted on the cover 6, on its inner side, parallel to the filling pipe 5, and the sealing cover 6 is made in the form of a disk 11 with a fitting 12 fastening the vapor exhaust hose 8 and connected to the disk 11 with the possibility of rotation relative to the latter using, for example, six rollers 13 of the overlay ring 14 with grooves made on the outer cylindrical surface of the ring 14 and provide ivayuschimi possibility of installing and fixing the sealing cover 6 to the necks of tanks of different sizes (not shown) and secure the cover on the neck 6 by fasteners neck of the tank itself.

Closed filling (figure 1) provides a reduction and removal of product vapor leaks from the tank. The tightness when the tank is closed is provided by the sealing cover 6. The sealing cover 6 of the riser (FIG. 2) consists of a patch ring 14 and a disk 11. The sealing cover 6 is fixed on the neck with fasteners of the tank neck itself. The number and design of the grooves on the ring 14 take into account the neck of the tanks of various types. The uniformity of the design is ensured by the rotation of the patch ring 14 relative to the disk 11 using six rollers 13. The sealing element 7 is made, for example, of rubber, the brand of which is selected for each product. The sealing element 7 is mounted on the cover 6 using, for example, screws 15. The hose 8 of the exhaust pipe is secured to the fitting 12 using clamps 16. The inner diameter of the hose 8 of the pipe 5 is 50 mm. An emergency level switch is installed on the lid 6, for which a locking mechanism 10 and a protective cylinder 9 are provided. Several protective radial holes 17 are provided in the protective cylinder 9 in order to ensure the same level of product in the tank and cylinder 9. The indicator is installed at the required height in the axial hole a protective cylinder 9 with a diameter of 21.8 mm with a gap and is clamped by the locking mechanism 10.

Closed filling for filling transport tanks works as follows.

Before starting work, the filling pipe 5 with the sealing cover 6 is under the action of the counterweight 2 in its highest position so that the end of the filling pipe 5 does not go beyond the dimensions of the rolling stock. When supplying the tank for filling, its neck is installed so that it is within the working area of the riser. The operator opens the lid of the tank and, manipulating the movable pipes 1 and the counterweight 2, lowers the filler pipe 5 with the sealing cover 6 onto the neck of the tank until the sealing element 7 comes into contact with it. Fasteners of the mouth itself are installed in the part of the grooves made on the outer cylindrical surface of the ring 14. and fix the cover 5 on it. Next is the filling of the product. Vapors of an aggressive product are discharged through a vapor exhaust hose 8. After filling, the operator disconnects the fasteners of the neck and removes the filler pipe 5 with a sealing cap 6 from the neck of the tank.
