Title:
FOREIGN MATTER REMOVAL DEVICE
Document Type and Number:
Japanese Patent JP2023176222
Kind Code:
A
Abstract:
To inhibit linear foreign matters from staying behind on a sieve surface by successfully separating the linear foreign matters included in a processing object from the sieve surface to discharge them to a foreign matter discharge part in a foreign matter removal device provided with a sieve structure for sieving processing objects into sieved lower materials passing through the sieve surface and foreign matters that do not pass through the sieve surface.SOLUTION: A foreign matter removal device is provided with a swinging drive part 35 for switching a posture of a sieve structure 20 between a processing posture for swinging the sieve structure 20 with a swinging shaft part 30 extending horizontally along a boundary part 17 between a processing object input part 12 and a foreign matter discharge part provided adjacently to it as a center, and making the sieve surface 22 cross the processing object input part 12 to receive the processing object X on the sieve surface 22, and a foreign matter discharging posture for flipping up the sieve surface 22 horizontally on a processing posture side for a prescribed flip-up angle α to discharge foreign matters A on the sieve surface 22 to a foreign matter discharge part 15. The flip-up angle α is set to 90° and more, and 180°or less.SELECTED DRAWING: Figure 1
