Conveying device for powdered and/or granulated material and mixtures of this material with liquids
View Patent ↗A conveying device for a mixture of free-flowing finely divided solid materials, in particular for powdered and/or granular (mixed) material, especially polymer granules with a liquid includes a telescopic pipe which is vertically arranged and can be flexibly fitted for conveying a mixture of preferably polymer granules with a liquid, for example for flushing a contaminated conveying device.
1. A conveying device comprising a telescopic conveying pipe and
a) arrangement of the conveying pipe ( 5 a ) on a mobile frame for transporting the conveying pipe to different cleaning points on a platform, the mobile frame comprising a pipe lifting/lowering device connected to the pipe for positioning the pipe at different docking devices on the platform;
b) a funnel ( 4 ), with a docking collar, at the inlet of the conveying pipe;
c) a ceiling centering means ( 2 ) above the funnel and having a sensor ( 3 ) adapted to detect funnel docking, the docking collar being configured to mount onto the ceiling centering means;
d) a flushing tube ( 5 b ) in flow communication with the conveying pipe and having a tube lifting/lowering device connected to the flushing tube; and
e) a lifting/moving device ( 7 , 8 ) selectively below the outlet of the flushing tube for removal of a bottom cover away from the outlet of the flushing tube.
2. The conveying device according to claim 1 , wherein sensors are attached to at least one of flanges or mating flanges of the conveying pipe.
3. The conveying device according to claim 2 , wherein the sensors are configured to detect correct docking of the flanges and transmit indicia to allow flushing.
4. The conveying device according to claim 1 , wherein the conveying pipe is arranged on the mobile frame for transporting the conveying pipe to different filling points on the platform.
5. The conveying device according to claim 4 , wherein the lifting/lowering devices are assisted by pneumatic drives.
6. The conveying device according to claim 1 , wherein the mobile frame includes a brake and, when the bottom cover is being removed, the brake is activated.
7. The conveying device according to claim 6 , wherein the brake is released when an initiator at a lifting magnet does not detect the bottom cover.
8. The conveying device according to claim 6 , characterized in that the brake is only released when the initiator at the lifting magnet does not detect a bottom cover.
9. The conveying device according to claim 1 , wherein the platform is configured to be moved by electrical drives.
10. The conveying device according to claim 1 , wherein the ceiling centering means is configured to position the conveying pipe.
11. The conveying device according to claim 1 , wherein the ceiling centering means is configured to be sealed to the funnel upon funnel docking.
12. The conveying device according to claim 1 , wherein the platform is configured to be moved by movable drives.
