Background of the Invention

Systems are known for transferring waste through pipeline differential pressure or suction. In these, waste is transported over long distances in the pipeline by suction. Typically, a vacuum apparatus is used to provide a differential pressure in which the vacuum in the transfer tube is achieved by vacuum generators, such as vacuum pumps or ejector apparatus. The transfer tube typically has at least one valve member that opens and closes to regulate the replacement air entering the transfer tube. The systems utilize feed points, such as waste chutes, at the material inlet end, into which material, such as waste material, is fed and from which the material to be transferred is transferred to the transfer tube by opening a drain valve member. The waste transfer is mainly effected by the pressure difference caused by the air flow. Airflow is usually achieved by suctioning air through the piping. Waste material, such as bagged waste material, is transferred from the feed point to the transfer tube and further to a separator for separating the waste from the conveying air. The separation device may be provided with a transfer device, such as a transfer member arranged in a cylinder-piston assembly, for transferring waste from the separation device to a waste container, for example a transport container. Such solutions having a separate separator device, for example a vortex separator, and a separate waste bin m, are suitable for very large systems where the space requirements of the waste station do not impose restrictions. Solutions are also known in which waste material is led directly into a waste container in a transfer tube, which at the same time acts as a separator device. These are mainly intended for smaller systems. Such a waste container / separator device 2 is often arranged similar to a conveyor. They are known in the art as your level separator containers. The problem with the known combinations of the waste container and the separator device, especially the level separator containers, is that some of the material, or certain types of materials, remain loosely packed and thus bulky in the container space.

The object of the present invention is to provide a completely new solution in connection with a pneumatic waste transport system. It is an object of the invention to provide a solution which avoids the problems of the prior art. Another object is to provide a solution that can effectively fill the container space of the waste container / separator with material.

At least one suction opening 58 is provided in the suction passage 57, 57 'along its length. In the embodiment of Figure 1-6, a plurality of suction openings 58 are provided arranged along the circumference of the suction passage 57, 57'. Further, an air-permeable wall portion 59 is provided in the tank space 68, such as a dense mesh, which allows air to pass, but prevents at least large particles of waste material from entering suction openings 58 of suction passage 57, 57 'and air tank wall 53 and one of 67 form a longitudinal chamber space of the reservoir 15 in which the suction passage 57, 57 'is provided. When the suction side of the vacuum generator 31 is coupled to the first suction passage 57 through the first fluid passage 34 and the connection 56, the suction acts through the suction openings 58 of the first suction passage and through the air-permeable wall 59 to the A, 101B, 101C. The material fed into the tank space 68 from the inlet 55 is directed to the active suction side in the tank space 68. In Figure 2, the suction acts on the tank space through the suction openings 58 of the first suction channel 57. The first valve 36 is then open. The second valve 36 'closes the fluid connection from the suction side of the vacuum generator to the second suction channel 57'. As shown in Figure 2, the material units W, such as bags containing waste material, are led from the transfer tube from the direction of the inlet 55 to the first suction passage 57 to the side of the container. According to one embodiment, the container space begins to fill from the opposite end of the container space 68 to the inlet 55.

The material is separated from the conveying air, for example by collision and gravity, so that the heavier material W is carried to the bottom of the container. A suction passage 57 is provided at the top of the waste container / separator device 50, which is connected to the suction side of the negative pressure generator 31. The conveying air exits from the mold portion 68 of the waste container / separator device 15 to the suction passage 57. The air-permeable wall 59 prevents at least larger particles of material from entering the suction passage. The smaller particles are filtered through a filter device 35 (Figure 1).

When material accumulates from the inlet 55 of the waste container / separator 50 with the conveying air 20, at least a portion of the material w initially collides with the rear wall 51 of the container and drops downwardly in the tank 68. As the filling progresses, the material W collides with the material already accumulated in the container.

Figure 6 shows an operating state in which a significant amount of material W has already accumulated in the container. As the waste container / separator 50 begins to fill, the suction effect increases in areas not yet having material W. As shown in Figure 6, the lateral suction effect increases side.
