Description

The utility model relates to the transport of goods in railway tank cars, in particular tank cars with a lower discharge.

In connection with the need to use railway tank cars with an extended service life, the issue of ensuring the safety of transportation of especially dangerous goods is urgent.

Currently, this problem is being solved by installing inserts inside the vehicle that prevent contact of the transported goods with the enclosing structures of the vehicle.

Known flexible liner for the carriage of goods in covered wagons (utility model patent No. 100039 of the Russian Federation, IPC B61D 17/00 (2006.01) Rudyuk V.A., Islomov B.B., Sivertsev A.S., Toriev B.Kh., Dudurgov R.M .; Rudyuk V.A. (RF). - No. 201007980; Stated March 5, 2010; Published on December 10, 2010, Bull. No. 34).

The insert has a shape close to a rectangular parallelepiped, corresponding in size to the internal dimensions of the car and made with the possibility of attachment to the inner surface of the car. The insert contains two side faces, two end faces, one lower face and one upper face corresponding to the shape of the car roof, made of flexible material, at least one loading sleeve located on the upper face and at least one unloading sleeve on side face. Details of the liner are interconnected by stitching.

The liner is attached to the inner surface of the car using fasteners made on the edges of the liner. In addition, the liner is additionally equipped with a ventilation valve located on one of the side faces and an unloading air bag located at the lower end edge of the liner and made equal to the width of the end face. The location of the discharge hoses and the ventilation valve corresponds to the location of the car doors.

The insert is intended for use in cars with sunroofs.

The liner works as follows.

First, the liner is installed in the car and fix it on the inner surface of the car. To do this, first attach the lower edge of the flexible liner to the inner surface of the gondola. The fastening elements sewn along the perimeter of the lower edge are fastened with mating elements at the junction of the platform and the side walls of the gondola car, or fastening fasteners on the side faces of the flexible liner to the mating elements on the inside of the side walls of the gondola car. After fixing the lower edge of the flexible liner, fix the upper edge of the flexible liner. Fasteners are attached sequentially starting from one side.

After installing the liner in the car and fixing it on the inner surface of the car, the cargo is loaded through the loading sleeve by simply filling the cargo. For a full load of the car, a ventilation valve is used, which ensures the removal of air from the inner volume of the liner. When loading the liner, the discharge cushion is deflated. After arriving at the destination, the wagon is unloaded. The wagon is unloaded through the unloading sleeve. For unloading, screw, container or pneumatic unloading systems can be additionally used. At the beginning of unloading, the discharge cushion is in a deflated state. After the bulk of the load has been unloaded from the insert, the discharge cushion is inflated through the inflation / descent means of the pillow. When inflating, the volume of the discharge cushion increases and the cargo remains, under the action of gravity, move to the discharge sleeves. In addition, through the ventilation valve, air is supplied to the inner volume of the liner and unloading is faster.

Installation of the liner in the car allows you to reliably protect the inner surface of the car from the transported cargo. After removing the liner from the car, any contamination remains inside the liner. Using the liner provides isolation of the internal volume of the car, expands the range of goods carried in the car. This allows you to transport both food and bulk cargo with a high level of dust formation, while maintaining the quality of the goods, eliminating the possibility of spilling cargo into the structural slots of the car during transportation, which excludes its interaction with the environment.

In addition, the use of the liner will allow to keep the car clean and, as a result, refuse to rinse and sanitize the cars after unloading, which leads to a reduction in the cost of empty cars for washing and to increase the turnover of the car.

The disadvantage of this utility model is the incomplete tightness of the liner, the presence of lateral, upper and lower faces, which does not allow to expand the list of transported goods, in particular liquids, and does not allow to expand the list of vehicles, in particular railway tank cars, due to the design features of the liner and features of its attachment to the design of the car.

Closest to the claimed technical solution is a flexible liner for the carriage of goods in railway tank cars (patent for utility model No. 118273 of the Russian Federation, IPC B61D 39/00, B61D 5/00 (2006.01).

A flexible liner for transporting goods in railway tank cars, contains a container made in the form of a cylinder, on the inside of which are located horizontal and vertical air channels that communicate with each other. The container is made of film material, the size corresponding to the internal dimensions of the vehicle. A loading sleeve is located in the upper part of the tank, made with cutouts in the upper part, the dimensions of which correspond to the sizes of the fastening and locking elements of the lid of the tank. The liner is also equipped with an inlet / outlet duct with a shut-off valve at the inlet, which is installed inside the boot sleeve with the possibility of communication with the horizontal air channel of the container and a drain cone located in the lower part of the container liner. All the details of the liner are interconnected hermetically by gluing, and the loading sleeve is mounted on the hatch of the tank car using a fixing device.

Installation of the flexible liner in the tank car, its loading and unloading are carried out as follows.

The insert through the hatch of the tank is placed in the tank car, the loading sleeve with the help of a fixing device is fixed on the hatch of the tank car. Then I open the shut-off valve of the inlet / outlet duct and the air entering through the duct fills the horizontal air ducts first and then the vertical air ducts. As a result, the liner capacity is inflated, filling the volume of the tank car, and then the shut-off valve closes. After installing the liner, the transported bulk cargo is poured through the loading sleeve, after filling the liner capacity by 3/4 of its volume, the shut-off valve is opened and, under the influence of the filling liquid, the air is forced out of the air channels.

After the normative filling of the volume of the tank car, the hatch is closed and the cargo is transported. After arriving at the destination, the hatch is opened and the transported bulk cargo is pumped out, then after pumping out the bulk cargo, the liner is removed, the top of the drain cone is cut off, the remaining liquid is drained and the liner is disposed of.

The advantages of the liner are its ease of installation, low labor costs in mounting and dismounting, ensuring the tightness of tanks.

The use of the liner allows you to minimize the need for steaming tanks for reuse, switch to transportation from one type of cargo to another without additional processing, extend the life of tank cars and ensure the safety of transportation of bulk cargo.

The disadvantage is that the structural features of the liner do not allow the transportation of bulk cargo in tank cars with a lower drain.

The objective of the utility model is the creation of a flexible liner for the transport of goods in rail tank cars with a lower discharge, which allows to expand the functionality of the liner and thereby increase the productivity of operations when transporting bulk cargoes.
