Existing pilot-scale roller kilns have long cycle times, low operating frequency at each station, a small number of saggers that can be processed in one operation, and a large overall footprint, which cannot meet the automation needs of experimental personnel. The sagger loading and unloading system of the roller kiln is now being optimized and improved to reduce space occupancy and meet the requirements of automatic operation.

[0003] A patent application with publication number CN115597367A discloses an automated loading and unloading production line for roller kilns and its operating method. This automated loading and unloading production line includes: at least three parallel roller kilns; a kiln inlet system and a kiln outlet system, respectively located at the inlet and outlet of each roller kiln; an outlet conveyor line with conveying inlets corresponding to the outlets of each roller kiln; a sagger-type corner module adapted to transfer saggers sealed on the outlet conveyor line to a cooling conveyor line; and a loading and unloading conveyor line adapted to receive saggers sealed on the cooling conveyor line via a first corner module and to seal and convey the saggers to the kiln inlet conveyor line via a second corner module. The kiln inlet conveyor line has conveying outlets corresponding to the inlets of each roller kiln. This automated loading and unloading production line uses at least three roller kilns matched with the conveyor lines, resulting in a large footprint and complex layout. Utility Model Content

[0037] Preferably, it also includes a heat insulation layer 15, which is disposed on the outer wall of the furnace body 1 and arranged around the furnace body 1 to prevent heat loss.

[0038] The working process of this pilot roller kiln is as follows:

[0039] The saggers and lids are placed on conveyor line 2. The sagger loading machine 6 loads the material to be sintered into the saggers. The material homogenizer 5 shakes the material in the saggers to make them uniform. The saggers are then stacked. The lid cleaning and lid placement machine 3 cleans the lids and places them on the corresponding saggers. The first elevator 101 sends the entire sagger downwards into the inlet transfer roller table 14. The saggers enter the kiln through the inlet replacement chamber 11 for sintering. After sintering, the saggers move from the outlet replacement chamber 12 to the outlet transfer roller table 13, and then are sent back to conveyor line 2 by the second elevator 102. The lid removal machine 10 removes the lids and places them next to the saggers. The sagger separating machine 9 removes the material from the saggers and puts them into the next material conveying cycle.
