Problems solved by technology

[0004] 1. The existing ceramsite rotary kiln can only agitate the sludge by its own rotation when drying the sludge. The heating effect of the sludge is poor, the drying efficiency is low, the work cost is high, the human and material resources are wasted, and the working time is increased;
[0005] 2. When the ceramsite rotary kiln works for a long time, it is impossible to lubricate the meshing parts of the gears, which will cause the gears to be prone to overheating or cracking, which will affect the service life of the equipment and increase the working cost;
[0006] 3. The used lubricating oil cannot be recycled conveniently, resulting in high lubrication costs, and the filtered lubricating oil cannot be quickly sent to the oil storage tank for secondary use, wasting human resources
