Definitions

• This invention is concerned with a transport container for the transport of bulk Material provided with a filling-hole in the upper part and an emptying device in the rear.
• All known transport containers of this kind are pressure vessels, in which positive pressure is produced for the unloading of the bulk material.
• This kind of transport containers have the disadvantage that they are suitable for the transport of bulk material only. And since they are pressure vessels, they are also very costly to build.
• a transport container based on the invention is characterized by that for the loading and unloading of also parcelled goods the container is provided with a side section that can be opened, and that the emptying device comprises a pneumatic pressure discharger with a pressure vessel into which the bulk material can freely flow from the container through a check valve and in which, with the check valve closed, pressure can be produced for discharging the bulk material through a discharge pipe.
• the transport container can be used to transport bulk material in one direction and parcelled goods on the return journey. Since the container is emptied by means of a pneumatic pressure discharger, the transport container need not be a pressure vessel and is therefore much simpler and much more economical to build than the known transport containers in question.
• An advantageous application of the invention is characterized by that the container is provided with two pressure dischargers and they are connected to a common discharge pipe, and that, by means of known technology, the pressure dischargers are arranged to work alternately. Thereby is achieved a continuous flow in the discharge pipe, which considerably speeds up the unloading of the transport container.
• Another application of the invention is characterized by that the discharge pipes of the pressure dischargers are provided with check valves between the pressure dischargers and the common discharge pipe.
• the pressure dischargers are made to operate smoothly by alternately opening and closing the check valves and thus made to work alternately in unloading the bulk material.
• a third application of the invention is characterized by that in the container, in the space between the removable side section and the pressure dischargers there is a removable partition wall. It is thereby possible to transport bulk material and parcelled goods at the same time.
• Figure 1 shows a transport container from the side.
• Figure 2 shows a transport container from behind.
• Figure 3 shows a pneumatic pressure discharger in section.
• the emptying device 3 comprises a pneumatic pressure discharger 5 with a pressure vessel 6 into which the bulk material can freely flow from the container 1 through a check valve 7. With the check valve 7 closed, it is possible to produce pressure in the pressure vessel 6 for discharging the bulk material through a discharge pipe 8.
• the container 1 is being tilted as the process of emptying goes on, and so the bulk material can freely flow into the emptying device 3.
• the container is provided with two pressure dischargers 5 and they are connected to a common discharge pipe 9 and, by means of known technology, the pressure dischargers 5 are arranged to work alternately, a continuous discharge flow is achieved for the bulk material.
• the discharge pipes 8 of the pressure dischargers 5 are provided with check valves 10 between the pressure dischargers and the common discharge pipe.
• a removable partition wall 12 with which the container 1 can be divided into separate rooms for bulk-material and parcelled goods.
• the operations of the pressure dischargers 5 and those of the valves can be simply arranged by means of known technology, such as pneumatic arrangements.
• a transport container based on the invention can be used both on lorries and on railway waggons.
• the emptying device 3 need not necessarily be in the rear of the container, as in the example, but it can as well be under the container, especially with those containers that are used on railway waggons.
• the emptying device can also be a detachable unit, in which case it is suitable for the emptying of various other containers.
