Description

The utility model relates to railway transport, namely to tank cars for pesticides and other petrochemical cargo.

Various technical solutions are known in the area under consideration.

The tank car model 15-5181 is known (see https://vagon.by/model/15-5181), designed to transport various chemical goods, including pesticides - styrene, acetone. The tank car includes a boiler, which through the frame structure rests on two bogies with a maximum calculated static axial load of 245 kN (25 tf), equipped with automatic couplers, braking equipment. The boiler is made of low-alloy steel and is equipped with a manhole covered by a hatch cover. The sealing unit of the hatch cover uses seals resistant to the transported goods. The boiler also has a safety valve closed by a membrane, which serves to prevent the pressure inside the boiler from increasing above the working pressure, an inlet valve to eliminate the vacuum, and openings for draining and filling operations located in the lower part of the boiler. The boiler has a length of 11200 mm.

The disadvantages of this tank car include the maximum calculated static axle load of 245 kN (25 tf), which allows it to be used only in the territories of states that have agreed on the operation of cars with an axle load of 245 kN (25 tf), the presence of a membrane unit, which is not mandatory for installation on cars for the transportation of goods permitted for transportation in cars with bottom discharge, the presence of two valves - a safety valve with a membrane unit and an inlet valve. In general, the noted disadvantages reduce the versatility of the tank car and make this car more expensive.

The tank car model 15-1280-01 is known (see https://vagon.by/model/15-1280-01), designed for the transportation of pesticides - styrene, ethylene glycol, antifreeze, acetone. The tank car includes a boiler, which is supported by two bogies through a frame structure, with a maximum calculated static axial load of 230.5 kN (23.5 tf), equipped with automatic couplers, braking equipment. The boiler is made of low-alloy steel and is equipped with a manhole covered by a hatch cover. The sealing unit of the hatch cover uses seals resistant to the transported goods. The boiler also has a safety inlet valve, which serves to prevent the pressure inside the boiler from increasing above the working pressure, as well as to eliminate a vacuum, for example, during vapor condensation in winter or when draining cargo with the hatch cover closed, and openings for draining and filling operations located in the upper part of the boiler. The disadvantages of this tank car include the upper location of the openings for draining and filling operations, which does not allow for the cargo to be drained by gravity and increases the unloading time. The boiler has a length of 10,770 mm, which, with a car length along the axles of automatic couplers of 12,020 mm, leads to a relatively small boiler volume (72.3 m ³ ), which leads to underutilization of the tank car's carrying capacity and makes the transportation of cargo with a lower density ineffective compared to pesticides (styrene). In general, the noted disadvantages reduce the versatility of the tank car. The specified car is the closest technical solution and was selected as the closest analogue.

The purpose of this utility model is to create a tank car in which it is possible to transport a wide range of goods, such as pesticides, petrochemical goods. The technical result of the claimed utility model is to expand the range of goods transported by the tank car for the transportation of pesticides and other petrochemical goods.

The specified technical result is achieved by the fact that the tank car for pesticides and other petrochemical cargoes, equipped with automatic couplers, has a boiler, which is supported by two bogies through a frame structure, has an opening for draining the transported cargo, located in the lower part of the boiler and covered by a drain device, which has three successively located valves, the valves have hermetic seals made of a material resistant to the action of the transported cargo. The parts of the drain device that come into contact with the transported cargo are made of a material resistant to its action, or can be covered with a material that ensures the resistance of the said parts to the action of the transported cargo.

The boiler is made of a material that is resistant to the effects of the transported goods, or the inner surface of the boiler is covered with a material that ensures the resistance of the said surface to the effects of the transported goods.

A safety device is installed on the boiler in its upper part, which is also equipped with hermetic seals made of a material resistant to the effect of the transported goods. The parts of the safety device that come into contact with the transported goods or its vapors are also made of a material resistant to the effect of the transported goods, or are covered with a material that ensures the resistance of the said parts to the effect of the transported goods.

The essence of the utility model is explained by a figure that depicts a general view of a tank car.

The positions on the figure indicate:

1 – automatic coupling;

2 – boiler;

3 – frame structure;

4 – trolley;

5 – drain device;

6 – safety device.

The utility model can be implemented as follows.

A tank car for pesticides and other petrochemical cargoes, equipped with automatic couplers 1, can be made with a length along the coupling axes of the automatic couplers of 12020 mm, is equipped with a boiler 2, which through a frame structure 3, for example, through a frame or two half-frames, rests on two bogies, for example, with a maximum calculated static axial load of 230.5 kN (23.5 tf) 4, the boiler 2 can be made with a length of at least 11000 mm, has an opening for draining the transported cargo, located in the lower part of the boiler 2 and covered by a drain device 5, having three successively located valves (not shown), preventing unintentional spillage of the cargo located in the boiler 2, the valves have hermetic seals (not shown) made of a material, for example, fluoroplastic, resistant to the action of the transported cargo. The parts of the drain device 5 that come into contact with the transported cargo are made of a material that is resistant to its action, for example, from grade 20GL steel, or can be coated with a material that ensures the resistance of the said parts to the action of the transported cargo, for example, treated with galvanizing.

Boiler 2 is made of a material resistant to the effect of transported goods, such as pesticides and other petrochemical goods, for example, from steel grade 09G2S. Also, to ensure the resistance of the inner surface of boiler 2 to the effect of transported goods, it can be coated with a material that ensures such resistance, for example, it can be galvanized.

A safety device 6, for example, a safety inlet valve, is installed on the boiler 2 in its upper part. The safety device 6 is equipped with hermetic seals (not shown) made of a material resistant to the effect of the transported goods, for example, of fluoroplastic, the parts of the safety device 6 that come into contact with the transported goods or its vapors are also made of a material resistant to the effect of the transported goods, for example, of CF 8M steel, or can be coated with a material that ensures the resistance of said parts to the effect of the transported goods, for example, treated with galvanizing.

The technical result is achieved as follows.

Due to the fact that the tank car for pesticides and other petrochemical cargoes is equipped with a boiler, which has an opening for draining the transported cargo, located in the lower part of the boiler and covered with a drain device, which has three successively located valves, preventing unintentional spillage of the cargo located in the boiler, it is possible to transport cargoes that require bottom draining, which has a positive effect on the expansion of the range of transported cargoes.

Due to the fact that a safety device is installed on the upper part of the boiler, which serves both to prevent the pressure inside the boiler from increasing above the working pressure and to eliminate the vacuum during draining with the hatch cover closed, it is possible to transport cargo that requires the use of a safety device in the boiler of a tank car, making it possible to carry out draining operations through the lower drain device, which makes it possible to transport part of the range of cargo that requires lower draining.

Due to the fact that the valves of the drain device and the safety device have hermetic seals made of a material resistant to the effect of the transported goods, and the parts of the drain device that come into contact with the transported goods, the parts of the safety device that come into contact with the transported goods or its vapors, as well as the boiler are made of a material resistant to the effect of the transported goods, or can be coated with a material that ensures the resistance of the said parts and the inner surface of the boiler to the effect of the transported goods, it is possible to transport such media, which expands the range of chemicals and other petrochemical goods transported by a tank car.

Thus, the proposed utility model with the specified set of essential features allows to expand the range of transported goods of a tank car for pesticides and other petrochemical goods by including part of the range of goods requiring bottom discharge, as well as part of the range of goods, including goods that are considered aggressive and can cause intensive corrosion of materials that are not resistant to it.
