8. A drying device for producing polyaluminium chloride according to claim 1, characterized in that: A blocking assembly (6) is provided on the support plate (1), the blocking assembly (6) comprising a blocking plate (61) rotatably mounted between the two support plates (1), an arc-shaped through hole (62) is provided on a side of the support plate (1) close to the first motor (420), a connecting column (63) is slidably mounted in the arc-shaped through hole (62), a third motor (67) is fixedly mounted on a side of the support plate (1) close to the first motor (420), and a swing plate (65) is fixedly mounted on an output end of the third motor (67).

9. A drying device for producing polyaluminium chloride according to claim 8, characterized in that: A second waist-shaped through hole (66) is formed at one end of the swing plate (65) away from the third motor (67); one end of the connecting column (63) is fixedly mounted at a middle position of the blocking plate (61); the other end of the connecting column (63) slides through the second waist-shaped through hole (66) and is fixedly mounted with a baffle (64).

10. A drying method for a drying device for producing polyaluminium chloride, characterized in that: The steps include: First, the second motor (422) is started, so that the second motor (422) drives the gear ring (421) to rotate through the first gear (423), so that the gear ring (421) drives the steam spray rod (42) to rotate in the drying barrel (2) through the rotating plate (41), so that the steam spray rod (42) performs steam drying on the material storage plate (46), and at the same time, the first motor (420) is started, so that the first motor (420) drives the reciprocating plate (416), the toggle rod (418) and the elastic scraper (419) to reciprocate in the material storage plate (46) through the reciprocating screw (45). , so that the reciprocating plate (416) reciprocates to push the extruded curved plate (415), so that the curved plate (415) drives the knocking hammer (413) on the connecting rod (410) to knock the material storage plate (46) through the sliding rod (414), so that the residual heat of the steam in the drying barrel (2) preheats the stored material in the material storage barrel (52) through the preheating pipe (53), and after the drying is completed, the blocking plate (61) is rotated to open the unloading plate (3), and then the hanging plate (44) and the rotating plate (47) are started, so that the material storage plate (46) is rotated between the two hanging plates (44) to facilitate the unloading operation.
