AI Technical Summary
In existing dual-shaft disc dryers, the simultaneous rotation of the two hot shafts causes material to adhere to the sides of the discs, creating cleaning dead zones and reducing heat transfer and drying efficiency.
The differential self-cleaning design is adopted. By setting scrapers and scrapers on the hollow disc and setting baffles and guide plates inside the hollow main shaft, the edge and surface of the hollow disc can be cleaned in all directions. At the same time, the jacket layer is used to improve the uniformity of heat source distribution.
It effectively avoids dead corners in disc cleaning, improves heat transfer and drying efficiency, and ensures the uniformity and efficiency of material drying.

Abstract
Claims
1. A differential self-cleaning twin-shaft disc dryer comprising a casing (1), characterized in that: Two hollow spindles (2) are inserted through the housing (1) and rotatably connected to it. Hollow discs (3) are equidistantly arranged on each of the two hollow spindles (2). The hollow discs (3) on the two hollow spindles (2) are staggered. Air boxes (4) are fixedly connected to the front and back of the housing (1). The two ends of the two hollow spindles (2) are respectively connected to the two air boxes (4). The two air boxes (4) are connected to the conduits (5). A fixing block (6) is fixedly connected to the bottom of the front air box (4). A drive gear (7) is fixedly connected to the back of the block (6). A large gear (8) and a small gear (9) are fixedly connected to one end of the front of the two hollow spindles (2), respectively. The large gear (8) and the small gear (9) mesh with each other. A motor (17) is fixedly connected to the front of the fixed block (6). The output shaft of the motor (17) passes through the fixed block (6) and is fixedly connected to the drive gear (7). The outer side of the drive gear (7) meshes with the large gear (8). A ring-shaped scraper (10) is fixedly connected to the bottom of the hollow disc (3).
2. A differential self-cleaning dual shaft disc dryer as claimed in claim 1, wherein: The top of the hollow disc (3) is fixedly connected to a ring of scrapers (11), which are square in shape.
3. A differential self-cleaning dual shaft disc dryer as claimed in claim 1, wherein: The box body (1) has a jacket layer (12) and the inner wall of the jacket layer (12) is connected to two horizontal pipes (13).
4. A differential self-cleaning dual shaft disc dryer as claimed in claim 1, wherein: The inner wall of the hollow spindle (2) is fixedly connected with partitions (14) arranged at equal intervals. The partitions (14) are located inside the hollow disk (3). The inner wall of the hollow spindle (2) has multiple sets of annularly distributed air inlets and outlets (15). The air inlets and outlets (15) are distributed on both sides of the partitions (14) and are connected to the hollow disk (3).
5. A differential self-cleaning dual shaft disc dryer as claimed in claim 1, wherein: The hollow spindle (2) is fitted with guide disks (16) arranged at equal intervals, and the guide disks (16) are located inside the hollow disc (3).
