Description

The invention relates to a device for unloading bulk material from railway wagons. It consists of a rotary tipper, a bulk material hopper with a dosing device, a reflective wall and conveyor belts.

Current bulk material unloading devices consisting of a rotary tipper, a bulk material container with rebound dispensing devices and a conveyor belt have a bulk material container positioned parallel to the axis of the rotary tipper, which necessitates the simultaneous placement of the conveyor belts. In order to convey the conveyor belts from underneath the hopper above the terrain, it is necessary to transfer an hourglass between the belts located below the bulk material container and the belts by which the bulk material is exported above the ground. Therefore, according to the present solution, for example, to export the material from below the container have at least two belts in one line with a transfer point, while the belt that exports the material above the terrain is usually situated perpendicular to the belt located under the bulk material container. The building of the bulk material container is converted as an underground building reaching a depth of up to 20 m below the terrain, and the belt sand-glass station is very demanding in terms of construction. This complexity of the construction solution makes it necessary to use only one belt below the hopper of loose material, at which failure the rotary tipper must be taken out of operation.

A more complicated situation arises when, for operational reasons, it is necessary to use two conveyor belts under the bulk material container. This is particularly necessary where the number of unloaders with a rotary tipper is small, ie. one or two. It is possible to select two belts either by different side of the rotary tipper with simple single belt transfer, separate for each belt at the other end of the rotary tipper, or by parallel running of two belts by short strips under bulk material containers and transfer feed the material from the belts below the bulk material containers on the side placed two discharge belts with several transfer points. The solution requires to realize the transfer of the belts in a part of a very demanding exposed area, as the lower structure is covered with material in the bulk material container, a rotary tipper and empty wagons. So far, the solution with three belts under the bulk material container has not been implemented with a quota of complexity and a large construction cost.

The above-mentioned deficiencies are eliminated and the problem is solved by a device according to the invention for unloading railway wagons, consisting of a tipping tipper, bulk material hopper with dosing device, reflecting wall and conveyor belts. the axis of the rotary tipper angle α = 5 to 12 °, wherein between the reflecting wall and the bulk material container there is an alignment wall facing the container.

The solution allows the bulk material to be conveyed through the belts from the bulk material container above the ground without transfer. It allows two, three or more belts to be installed in parallel, so that in case of a belt failure it is not necessary to shut down the device. The lower building part is relatively simple, since there is no need to build the transfer of belts under the rotary tipper. Building an overfill above the terrain is not as demanding as under the reservoir.

2 of a tilt tip, a bulk material container with a dispensing device, a reflector and conveyor belts, the essence of which is that the axis of the bulk material container located below the rotary tipper is folded into the podium with the axis of the tiltable tip angle α = 5 to 12 °, with the wall and the bulk container, the buffer wall faces the container. The solution allows the bulk material to be discharged through the belts from below the bulk material reservoir above ground without overfilling. It allows two, three or more belts to be installed in parallel, so that in the event of a belt failure it is not necessary to set up the device. The lower building part is relatively simple, because it does not need to incorporate belts dips under the rotary cutter. Building a transfer over the terrain is not as demanding as it is under the magazine. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings show an apparatus for unloading railway wagons, comprising a rotary tipper, a bulk material container with a dispensing device and conveyor belts. Fig. 1 is a plan view, Fig. 2 is a front elevation, Fig. 3 is a side elevational view of a solution with a bulk material sub-tray, Fig. 4 is a cross-sectional view of a bulk material container with three conveyor belts as an alternative. The device consists of a rotary tipper 1, under which a hopper 2 of a loose material is placed, the axis 21 of which in a planar position with the axis of the rotary tipper 11 the angle of the object is a device for unloading loose material from railway carriages, consisting of a rotating tipper a bulk material reservoir with a dispensing device, reflective panels and conveyor belts, characterized in that the axis (21) of the bulk material reservoir (2) located below the rotary tipping α = 5 to 12 ° and which is provided with a dispensing device 23, dispensing material for conveyor belts 22, in the case of a heater tunnel 26, respectively. The dosing device can be selected according to the type of material. The material expelled from the carriage 12 by rotating the rotary tipper 1 in the indicated direction 28 impinges on the reflective wall 24, located at the side below the rotary tipper, where the material from the carriage 12 is released when tilted in the specified direction of rotation of the rotary diverter. The location of the reflector 24 is determined by calculation or modeling tests according to the type of particulate material, so that the material does not spill over the reflector 24 out of the bulk material reservoir over the entire rotation range of the rotary tipper 28. The conveyor belts 22 are located below the bulk material container 2, following the direction 21 of the container 2, and the rising material angle of the material is brought out of the container above the ground without a transfer. FIG. 4 depicts a solution of a bulk material container 2 having a triple conveyor belt 22 with dispensers 23. The solution is advantageous in the case of a permanent unloading of a high number of wagons. The proposed solution can be used for most common types of rotary tipper materials, such as coal, ore, limestone coke, and the like.
