Abstract
A device and method for conveying bulk material, said device comprising a movable conveying member and an outer wall that is stationary in relation to the conveying member, wherein the device is connected to a further processing chamber for receiving and further processing the bulk material and a dynamic seal is used which seals with respect to the differential pressure between the further processing chamber and regions lying upstream in the process. A seal element of the dynamic seal formed of a sealant in the form of a material pattern or material seal that can be regenerated during operation of the conveying device, wherein the seal element is provided from a branch flow of the bulk material to be conveyed or from a separate sealant source.
Claims12
A device for conveying bulk material, the device comprising:
- a movable conveying member;
- an outer wall that is stationary in relation to the conveying member;
- a dynamic seal that seals with respect to a differential pressure between a further processing chamber and regions lying upstream in the process, the device being connected to the further processing chamber for receiving and further processing the bulk material;
- and
- a seal element of the dynamic seal comprising a sealant in a form of a material charge or material seal that is adapted to be regenerated during operation of the conveying device, the seal element being provided from a branch flow of the bulk material to be conveyed or from a separate sealant source.
A method for conveying bulk material into a further processing chamber or a pressurized chamber, the method comprising:
- sealing a conveying device with respect to ambient pressure or a bulk material source;
- and
- providing a seal element of a dynamic seal to seal the conveying device, the seal element being formed from a branch flow of the bulk material flow to be conveyed and/or a separate seal flow.
