The device applies to the transportation and storage of viscous liquids, namely, devices warmup of these liquids to expedite their discharge from tanks, cleaning tanks.

A device for cleaning tanks containing lifting and lowering the bar located in the lower part of the cylindrical chamber with a nozzle outlet for directing jets of steam and pipes for connecting the hollow rod with a cylindrical chambers [1].

As the closest analogue may be made to the device for faster draining of liquids from tank cars, containing a hollow rod, the upper end of which is connected to the steam generator, the bottom end fixed end we are the analogues provides a significant acceleration of the process of heating a viscous fluid, and accordingly, the acceleration drain while reducing steam consumption.

This effect is ensured by the two-stage heating viscous fluids and influence in the second stage by spraying steam under high pressure, which is achieved due to the fact that the lower portion of the rod is made narrow, the device has a lower steam nozzle, formed by the lower end of the narrowed section of the rod and the surface of a truncated cone at the upper end of the fairing, made in the form of a cylinder located coaxially relative to the hollow rod and placed in the mixing chamber formed by the inner surface of the cylindrical shell with the outer surface of the fairing, fastened together by edges, with the steam nozzle is formed coaxial with the casing and the outer surface of the rod, and end cap are made in the form of a slotted nozzle formed by the lower edge of the shell and the disk mounted on the lower end of the fairing, and a disk provided with apertures for the flow of hot liquid directly into a drain pipe in the tank, and on the lower surface of the disc fixed cone.

In the second embodiment, the effect is achieved due to the fact, th is claim with Radome, enshrined in its center and is made in the form of a truncated cone, is placed in the cavity of the lower end of the rod, and the lower surface of the disk fixed cone, the device is equipped with an extra disc mounted on the lower end of the rod, made in the odds of the socket, the inner surface of the socket rods and the surface of the disk to form the lower fairing steam nozzle and the gap between the disc and the additional disk forms a slit nozzle.

In Fig. 1 shows a device for accelerating discharge of viscous liquids (option 1); Fig. 2 is a device for accelerating discharge of viscous liquids (type a-a) of Fig. 3 is a device for accelerating discharge of viscous fluids (option 2).

The device according to the first embodiment (Fig.1) consists of a hollow rod 1 with a narrowed lower section, the upper end of which is connected to the steam generator (not shown), and the bar is installed inside the cleaned containers vertically above the discharge pipe of the tank so that the lower end of the device were not higher than 50-100 mm from the bottom of the tank. On the rod 1 is mounted an annular steam nozzle 2 and the lower steam nozzle 3. Top steam nozzle 2 is formed coaxial with the casing 4 and the outer surface of the rod 1, anonym in the form of a cylinder with the upper face in the form of a truncated cone. Lower steam nozzle 3 is placed in the mixing chamber 6 formed by the inner surface of the cylindrical shell 7 and the outer surface of the nacelle 5. Rod 1, the deflector 5 and the shell 7 is bonded between the ribs 8. On the lower end of the device installed end cap, made in the form of a slotted nozzle 9, formed by the lower edge of the shell 7 and the disk 10 mounted on the lower end of the deflector 5. The disk 10 provided with holes 11 for supplying hot liquid directly into a drain pipe in the bottom of the emptied container (not shown) and its lower surface is welded to the cone 12 to facilitate entry of the device into the volume of the viscous fluid.

The device according to the second variant (Fig.2) similar to the first one contains the rod 1, but without the constricted area, with mounted on it a steam nozzle 2 and the casing 4, and the lower steam nozzle 3 is formed by a socket of the lower end of the rod 1 and the upper surface of the disk 10, with a fixed fairing 5 end of the nozzle and crevice nozzle 9 is formed with an extra disc 13 mounted on the lower end of the rod 1 and the disk 10. As in the first embodiment, the disk 10 provided with holes 11, and its lower surface is welded to the cone 12, and the rod 1, dovolno second options is as follows.

Rod Assembly with head lowered vertically into the container (not shown) opposite the drain hole in the bottom of the tank at a distance of 50-100 mm from the bottom of the tank. The steam from the steam generator tubing is connected to the rod 1 is in its cavity, which partially through the steam nozzle 2 enters the tank, thereby pre-heating the surrounding viscous fluid. Heated viscous liquid is pumped into the mixing chamber 6, where it is additionally heated by steam entering the chamber through the bottom of the steam nozzle 3 of the hollow rod 1. Heated in two stages steam heater (nozzle 2, and 3) the liquid flows through the slit nozzle 9 into the vessel and through the openings 11 in the disk 10 directly into the drain pipe capacity.

The proposed device due to the intensive flow of hot liquid directly into the bottom region of the vessel through the slit nozzle and the discharge pipe through the perforated disk provides a significant acceleration of the process of heating a viscous liquid and, accordingly, the acceleration drain, while reducing the consumption of steam, because two-stage heating of the viscous fluid is almost completely eliminates the release of steam from the tank.

This Crostata design allows it to be recommended for use for heating is less viscous liquids and especially for washing and steaming containers.

Along with the reduction of weight and effort to enter the device in the volume of viscous fluid in 2-3 times is ensured in comparison with existing devices, reducing the time of warm-up and emptying, as well as steam flow rate about 1.5 times.
