At the same time, the threaded shaft 206d is rotatably connected to the movable frame 206a through a thread. When the threaded shaft 206d is rotated, the movable frame 206a can be driven away from or close to the fabric box 102, so that the driven shaft 201c is away from or close to the driving shaft 201a, so that the two fabric rollers 201b are moved away from or close to each other, thereby changing the material discharge amount of the fabric roller 201b.

[0062] When in use, firstly, the wet barium sulfate is conveyed from the feeding mechanism 101 to the cloth box 102, and is squeezed by the two cloth rollers 201b so that the wet barium sulfate falls from between the two cloth rollers 201b onto the top of the conveyor belt 103, and is conveyed to the microwave cavity 105 by the conveyor belt 103, and is subjected to microwave drying treatment. At the same time, the generated water vapor is extracted by the dehumidifying mechanism 107, and the dried barium sulfate is conveyed to the discharge port 108 through the conveyor belt 103, thereby completing the drying treatment of the barium sulfate. This solves the problem that when the device is in use, the rotating drum needs to be continuously loaded and unloaded, which is inconvenient for continuous drying treatment of the barium sulfate and is not suitable for large-scale production of barium sulfate.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
