Inside the base 1, heating wires 17 are arranged for heating and drying aerogels.

[0036] A stirring shaft 15 is rotatably arranged in the drying kettle 3. An installation seat 26 is fixedly arranged on the top of the drying kettle 3, and a first motor 4 is fixedly arranged on one side of the installation seat 26. The output end of the first motor 4 is fixedly connected with the stirring shaft 15, which is used for driving the stirring shaft 15 to rotate. Two groups of stirring spoons 16 are fixedly arranged on the outer wall of the stirring shaft 15, which are used for stirring aerogels.

[0037] In order to drive the rotating shaft 11 to rotate and overturn the drying kettle 3, a driving member is arranged. Specifically, the driving member comprises a worm gear reducer 6 fixedly arranged on one side of the support frame 2, and the output end of the worm gear reducer 6 is fixedly connected with the rotating shaft 11. A second motor 7 is also fixedly arranged on one side of the support frame 2, and the output end of the second motor 7 is fixedly connected with the input end of the worm gear reducer 6. In this way, when the second motor 7 is started, the rotating shaft 11 can be driven to rotate through the worm gear reducer 6, and then the drying kettle 3 is overturned. After overturning is completed, the worm gear reducer 6 can also lock the drying kettle 3 to ensure its stability.

[0038] In order to ensure that the inlet and outlet pipes 5 do not leak when the drying pot 3 is turned over, a sealing mechanism is provided. Specifically, the sealing mechanism includes a baffle 8 fixed on one side of the support frame 2, which is arc-shaped.
