Description

The present invention relates to mechanical engineering, in particular, to devices for heating and cleaning viscous products in boilers, tanks and other containers.

The purpose of the invention is the expansion of technological capabilities, simplifying the design and operation.

These goals are achieved by the fact that the tank for transporting fluid goods contains a cylindrical body which is installed, with the possibility of movement along it, a piston. The body is made with a steam jacket and has elements connecting to the steam line from the end sides. Along the casing, guides are attached to its inner walls, which are in contact with the groove on the piston. The piston around the perimeter is equipped with an elastic seal.

New in comparison with the prototype is the following: the casing is made with a steam jacket, the casing is equipped with elements connecting to the steam pipe from the end sides, the casing is equipped with drain pipes, guides are attached along the internal walls of the casing, grooves are made in the piston, grooves in the piston are in contact with guides.

Comparison of the proposed solution with other technical solutions shows that the case with a steam jacket, connecting elements to the steam line and drain pipes are widely known.

However, when they are introduced in this connection with the other elements in the inventive device, the above differences lead to the expansion of technological capabilities and simplification of the design.

Figure 1 shows a longitudinal section of a tank for the transport of fluid cargo: figure 2 is a view aa in fig. 1.

The boiler 1, which is formed by a cylindrical body 2 and end walls 3 and 4, has a steam jacket 5, which is equipped with front 6 and rear 7 elements connecting to the steam line (not shown), as well as drain pipes 8, 9, 10. Two more are provided connecting elements 11 and 12 to the steam line (not shown) for supplying steam to the space between the piston 13 and the end walls 3 and 4. In the boiler, pores are arranged to move along it

1811502 AZ tire 13. An elastic seal 14, for example, made of oil-resistant rubber, is fixed along the perimeter of the piston 13, and stops 15 and 16 are provided in the center on two opposite sides of the piston 13. Slots 17 are made in the piston 13, which contact with three guides 18. The latter equidistant relative to each other and rigidly fixed to the inner surface of the housing 2.

The device operates as follows.

A tank, for example, a railway tank, is fed in the usual way to the place of unloading. The steam is connected to the steam jacket 5. Heat the contents, for example, bitumen, to a temperature of minimum fluidity (for example, for bitumen grade 760 ° C). After the bitumen flowing down from the drain pipes 8, 9. 10 open the drain pipe 10 and open the connecting element 11, steam is supplied to purge the space between the piston 13 and the end wall 3. When a steam stream appears from the drain pipe 10, it is closed and the steam pressure is pumped to 0 , 7 atm. This pressure in the space between the piston and the bitumen-free part of the tank is maintained at all times during unloading. Under the action of steam, the piston 13 begins to move along the guides 18 towards the opposite end wall 4 of the boiler 1, squeezing bitumen, which flows from the drain pipes 8 and 9. When the piston 13 passes through the hole, the drain pipe 9, the steam jet will break out and the pipe 9 is closed . The piston 13 continues to move and the remainder of the bitumen is drained through the drain pipe 8. Moreover, since the steam jacket 5 warms up all the time and the steam is inside the boiler, bitumen that remains on the walls after the passage of the piston 13. is completely washed off and settles on the bottom of the boiler in the form of a hot emulsion. This emulsion after unloading the boiler is poured into containers (not shown in the drawing) separately from bitumen and then, if necessary, separated from water bitumen by known methods. When the contact 15 with the inner surface of the end wall 3 of the boiler 1, the piston stops. At the same time, inside the boiler 1, the pressure will increase sharply and the blasting valve will work. The supply of steam to the boiler 1 and to the steam jacket 5 is stopped, at the same time the drain pipes 9 and 10 are opened and the hot emulsion flows separately from the bitumen into a container (not shown in the drawing). If necessary, water is separated from bitumen by known methods. The tank serves on the formation of the empty. This completes the cycle of simultaneous unloading of the tank and its cleaning.

Technical appraisal and economic benefits consist in expanding the technological capabilities of unloading, both in storage facilities and in various ones, including located on the wheels of the tank, and also combines the process of unloading and cleaning, for example, tanks, and the latter reduces labor costs.
