An extrusion mechanism is arranged above the conveyor belt 2, and the extrusion mechanism is above the conveyor belt 2. In this way, when the conveyor belt 2 transports bauxite, the extrusion mechanism contacts the conveyor belt 2 to squeeze the bauxite on its surface, so that the water inside the bauxite is squeezed out. At the same time, the bauxite is attached to the surface of the conveyor belt 2 at this time, which is convenient for subsequent solid-liquid separation. A water storage device is arranged at the right end of the bottom of the base 1. Mechanism, the separated water can be collected through the water storage mechanism, a dehydration mechanism is arranged on the left side of the water storage mechanism, and the dehydration mechanism is located at the bottom left end of the base 1, the bauxite that has been squeezed to separate water can be heated by microwaves through the dehydration mechanism, so as to make it dehydrated more fully, a scraper 16 is arranged above the dehydration mechanism, the right end of the scraper 16 is arranged in contact with the lower surface of the conveyor belt 2, and the left end of the scraper 16 is connected to the base 1, by setting the scraper 16, the bauxite attached to the surface of the conveyor belt 2 can be scraped off and enter the interior of the dehydration mechanism.

[0024] Specifically, the extrusion mechanism includes an outer shell 3, a limit rod 4, a screw rod 5 and an extrusion roller 6.
