The utility model discloses a fly ash ceramsite sintering kiln, in which the raw ball is stacked on the platform through the conveyor, and the raw ball passes through the kiln inlet door and enters the annular sintering chamber. After the preheating, sintering, and cooling process, the fly ash ceramsite passes through the discharge port, through the scraper to the leaker, and is transported to the finished product yard by the conveyor.

The circular plate is fixedly sleeved on the outer wall of the spiral auger, and the spiral auger is connected to the non-center of the circular plate. The U-shaped rod is provided at the bottom of the filter. By connecting the spiral auger to the non-center of the circular plate, the spiral auger drives the circular plate to perform eccentric motion when it rotates, thereby continuously squeezing the U-shaped rod.

[0010] Preferably, a limiting rod is fixedly installed at the bottom of the material trough, and the limiting rod passes through the U-shaped rod and is slidably connected to the U-shaped rod. A spring is sleeved on the outer wall of the limiting rod, and the two ends of the spring are respectively fixedly connected to the bottom of the inner wall of the U-shaped rod and the bottom of the material trough.

[0014] 2. The fly ash ceramsite sintering furnace drives the circular plate to do eccentric movement through the spiral auger when conveying raw materials. When the circular plate squeezes the U-shaped rod, the U-shaped rod moves up to push the filter screen. When the circular plate does not squeeze the U-shaped rod, the filter screen moves down to reset. In this way, the filter screen vibrates up and down repeatedly, thereby improving the filtration efficiency and avoiding clogging of the raw materials. BRIEF DESCRIPTION OF THE DRAWINGS
