6. The device for preparing a foamed ceramic thermal insulation board according to claim 5, characterized in that: The top end of the dredging rod (37) extends to the top of the flow guide pipe (18), and the dredging rod (37) is arranged in a rectangular shape.

7. A foamed ceramic thermal insulation board and its preparation method, characterized in that: The device for preparing a foamed ceramic thermal insulation board according to claim 6 comprises the following steps: S1. Connecting the feed pipe (7) with an external raw material discharge pipe so that the external raw material enters the feed pipe (8) through the feed pipe (7) and is then sprayed into the material bin (4) through the spray head (19). During this process, the first drive motor (10) is started, and the output end of the first drive motor (10) drives the connecting shaft (11) to drive the rotary disk (12) to rotate in a circle, thereby driving the rotary push column (27) to move the rotary push frame (17) up and down, thereby pulling the feed pipe (8) up and down through the pulling rod (28), thereby improving the flow of raw materials inside the feed pipe (8), thereby avoiding the accumulation of raw materials inside the feed pipe (8) to cause blockage, and thus facilitating the discharge of raw materials inside the feed pipe (8); S2, starting the fan (13), wherein the fan (13) guides the waste heat inside the sintering furnace (2) into the second corrugated pipe (20) through the return air pipe (6), and then sprays it into the feed pipe (8) through the nozzle (22), thereby preheating the raw materials inside the feed pipe (8), thereby improving the utilization rate of the waste heat inside the sintering furnace (2), and at the same time allowing the preheated raw materials to enter the sintering furnace (2) to accelerate the efficiency of raw material sintering; S3, starting the two second drive motors (31), wherein the output end of one second drive motor (31) drives one of the winding rollers (30) to release one of the pulling ropes (32), and the output end of the other second drive motor (31) drives another of the winding rollers (30) to reel in another of the pulling ropes (32), thereby pulling the sliding sleeve (25) to drive the semi-arc stirring block (26) to move laterally, thereby stirring the material accumulated inside the conveying pipe (8), thereby preventing the material from adhering to the inside of the conveying pipe (8), and further improving the fluidity of the raw materials inside the conveying pipe (8); S4. When the semi-arc stirring block (26) contacts the dredging rod (37) during the process of lateral movement, the dredging rod (37) is pushed to pull the second arc spring (42) through the swing shaft (38) and the second connecting plate (40); when the semi-arc stirring block (26) is separated from the dredging rod (37), the second arc spring (42) pushes the swing shaft (38) to drive the dredging rod (37) to reset, so that the dredging rod (37) can stir the inside of the guide tube (18), thereby dredging the inside of the guide tube (18), thereby avoiding blockage inside the guide tube (18), thereby improving the patency of the guide tube (18).
