A method in a pneumatic material conveying system, such as in a waste conveying system, said conveying system comprising at least one feed point (61) of material, particularly waste material; a material conveyor pipe (100) that is connectable to the feed point (61); and a separator device (20), wher
A method in a pneumatic material conveying system, such as in a waste conveying system, said conveying system comprising at least one feed point (61) of material, particularly waste material; a material conveyor pipe (100) that is connectable to the feed point (61); and a separator device (20), where the material to be conveyed is separated from the conveyor air; as well as means (3) for creating a pressure difference in the conveyor pipe (100), at least for the duration of the process of conveying the material. In the method, material is conveyed further from the separator device (20) to the transport container (51), particularly a waste container, by employing in the conveying of material from the separator device to the transport container means (3) of the material conveying system for creating a pressure difference.

1. A method for conveying material in a pneumatic material conveying system, said conveying system comprising; at least one feed point of the material;a separator device having an input port and an output port;a transport container with an input port and an output port;a vacuum pump device having a pressure side and a suction side;a material conveyor pipe having one end connected to the input port of the separator device and extending to the at least one feed point;at least one first conveyor channel having one end connected to the output port of the separator device and an opposite end connected to the input port of the transport container;at least one second conveyor channel having one end connected to the output port of the transport container, and an opposite end connected to the suction side of the vacuum pump device;wherein the method for conveying the material using the conveying system comprises:activating the vacuum pump device to create a pressure difference in the material conveyor pipe in order to convey the material through the material conveyor pipe and into the separator device; conveying the material from the separator device and into the transport container by a suction created by the vacuum pump device; andat least part of conveyor air on the pressure side of the vacuum pump device is conducted to an upper part of the separator device. 2. The method according to claim 1, wherein the conveying system further comprises: at least one separator element which is arranged on the suction side of the vacuum pump device in a position between the transport container and/or the separator device and the vacuum pump device, andthe method further comprising:activating the at least one separator element in order to separate solid particles from the conveyor air. 3. The method according to claim 1, wherein the conveying system further comprises: an actuator located adjacent to the separator device,a material stirring and conveying device provided with a screw located in a lower portion of the separator device,the method further comprising:activating the screw of the material stirring and conveying device in order to stir and convey the material contained in the separator device towards the at least one first conveyor channel connected to the separator device. 4. The method according to claim 1, the method further comprising: activating the vacuum pump device to create an underpressure in the at least one second conveyor channel. 5. The method according to claim 1, wherein the method further comprises: feeding the material to the material conveyor pipe through the at least one feed point. 6. The method according to claim 1, wherein the conveying system further comprises: at least one valve element located between the at least one feed point and the material conveyor pipe,the method further comprising:adjusting an amount of the material and an amount of makeup air fed into the material conveying pipe by opening and closing said at least one valve element. 7. The method according to claim 1, wherein the conveying system further comprises: a transport vehicle, and the transport container is provided in the transport vehicle,wherein the at least one first conveyor channel connects a first portion of the transport container to the separator device, andthe at least one second conveyor channel connects a second portion of the transport container to the suction side of the vacuum pump device. 8. The method according to claim 1, wherein the conveying system further comprises: at least one second separator element which is arranged on the suction side of the vacuum pump device in a position between the transport container and/or the separator device and the vacuum pump device, andthe method further comprising:activating the at least one second separator element in order to separate solid particles from the conveyor air. 9. The method according to claim 1, the method further comprising:activating the vacuum pump device to create an underpressure in the at least one second conveyor channel. 10. The method according to claim 1, wherein the conveying system further comprises: a dust filter located between the separator element and the suction side of the vacuum pump device. 11. A method for conveying material in a pneumatic material conveying system, said conveying system comprising: at least one feed point of the material; a separator device having an upper part and a lower part;a transport container with a first portion and a second portion;a vacuum pump device having a pressure side and a suction side;a material conveyor pipe having one end connected to an input port of the separator device and extending to the at least one feed point;at least one first conveyor channel having one end connected to the lower part of the separator device and an opposite end connected to the first portion of the transport container;at least one second conveyor channel having one end connected to the second portion of the transport container, and an opposite end connected to the suction side of the vacuum pump device;wherein the method for conveying the material using the conveying system comprises:activating the vacuum pump device to create a pressure difference in the material conveyor pipe in order to convey the material through the material conveyor pipe and into the separator device; andconveying the material from the separator device and into the transport container by a suction created by the vacuum pump device. 12. The method according to claim 11, wherein at least part of conveyor air on the pressure side of the vacuum pump device is conducted to an upper part of the separator device. 13. The method according to claim 11, wherein the conveying system further comprises: at least one second separator element which is arranged on the suction side of the vacuum pump device in a position between the transport container and/or the separator device and the vacuum pump device, andthe method further comprising:activating the at least one second separator element in order to separate solid particles from the conveyor air. 14. The method according to claim 11, wherein the conveying system further comprises: an actuator located adjacent to the separator device,a material stirring and conveying device provided with a screw located in a lower portion of the separator device,the method further comprising:activating the screw of the material stirring and conveying device in order to stir and convey the material contained in the separator device towards the at least one first conveyor channel connected to the separator device. 15. The method according to claim 11, further comprising: a dust filter located between the separator element and the suction side of the vacuum pump device.
