[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: Reference Figure 1-6 The dehydration device shown in the figure is used for the production of aluminum hydroxide with low oil absorption value, including a dehydrator body 1 and a track 2, a push plate trolley 3, and a filter plate 4. A track 2 for sliding the push plate trolley 3 is provided on the dehydrator body 1, and a chain is provided at the bottom of the track 2. The chain is driven by a motor, and the chain is connected to the push plate trolley 3 to control the movement of the push plate trolley 3. The filter plate 4 is slidably connected to the dehydrator body 1, and the movement of the filter plate 4 on the dehydrator body 1 is controlled by the push plate trolley 3.

[0026] As an implementation method in this embodiment, an auxiliary mechanism is provided on the filter plate 4, the auxiliary mechanism: the left and right outer walls of the filter plate 4 are provided with two sets of symmetrical fixed blocks 42, the fixed blocks 42 are T-shaped structures, the lifting frame 8 is a U-shaped structure, and its vertical section is provided with a slide 81 adapted to the fixed block 42. In order to prevent the lifting frame 8 from falling off from the fixed block 42, a top screw hole 82 communicating with the slide 81 is provided on the outer wall of the lifting frame 8. The top screw hole 82 is internally threaded with a top screw, and the top screw is located below the fixed block 42 to achieve lifting and lowering. The frame 8 is limited; two groups of front-to-back symmetrical fixing members 9 are provided on the outer outer walls of the two groups of lifting frames 8, and the end faces of the fixing members 9 are provided with grooves, which are connected to the outside through the through holes 91 provided on the inner wall. The two groups of through holes 91 are connected by a scraping rope 11, and are threaded into the groove through the fixing bolts 10 to limit the scraping rope 11 and realize the fixation of the scraping rope 11. The scraping rope 11 is located above the outer wall of the filter plate 4. Under the control of the driving mechanism, the lifting frame 8 is controlled to rise and fall, and the scraping rope 11 removes the powder cake attached to the filter plate 4.

[0027] A groove 83 is provided on the outer wall of the lifting frame 8 to protect the scraping rope 11 and prevent it from being loosened due to excessive arc during the lifting process.

[0028] As an implementation method in this embodiment, in order to facilitate the scraping rope 11 to stick close to the outer wall of the filter plate 4, the scraping rope 11 is located at the edge of the top of the filter plate 4, and a guide slope 41 is provided at the top edge of the filter plate 4. This design facilitates the lifting and lowering of the scraping rope 11.

[0029] As an implementation method in this embodiment, the driving mechanism is as follows: a rack 5 is provided above the push plate trolley 3, the lifting gear 6 is rotatably connected to the outer wall of the filter plate 4, and teeth are provided on the inner wall of one side of the lifting frame 8, and the teeth and the lifting gear 6 are engaged with each other. In order to automatically drive the lifting gear 6 to rotate, a driving gear 7 is provided in this embodiment that is coaxially arranged with the lifting gear 6. The driving gear 7 is coaxially arranged with the lifting gear 6, and the driving gear 7 and the rack 5 are engaged with each other. When the push plate trolley 3 drives the filter plate 4 to move, the driving gear 7 rotates on the rack 5, thereby transmitting its rotational power to the lifting gear 6, and driving the lifting frame 8 to perform lifting and lowering movements.

[0030] The working principle of this utility model is as follows: after completing the dehydration task, the chain is driven by the motor on the track 2 to drive the push plate trolley 3 to move. The push plate trolley 3 moves the filter plates 4 forward from front to back in turn, so that the filter plates 4 are separated. During the separation process, the driving gear 7 rotates on the rack 5, and the rotation power is transmitted to the lifting gear 6. The lifting gear 6 engages with the rack on the lifting frame 8 to control the lifting of the lifting frame 8. The lifting frame 8 cooperates with the fixed block 42 through the slide groove 81 to achieve position limiting, and the lifting frame 8 is guided to rise and fall by the fixed block 42. When lifting, the scraping rope 11 is assisted by the guiding inclined surface 41 to lift and fall along the outer wall of the filter plate 4, thereby removing and peeling the powder cake and assisting in the collection of the powder cake after dehydration.

[0031] When maintenance is required, the scraper rope 11 can be released from the fixing bolt 10 by unscrewing the fixing bolt 10, and then the end of the scraper rope 11 can be pulled out from the through-hole 91. Then, it can be decided whether to replace the scraper rope 11 based on the wear of the scraper rope 11. After the maintenance is completed, the scraper rope 11 is reinserted into the through-hole 91 and the fixing bolt 10 is screwed into the fixing part 9 to complete the installation of the scraper rope 11 (when installing the scraper rope 11, the scraper rope needs to be located in the groove 83. The design here is to provide an overload protection for the scraper rope 11).

[0032] By unscrewing the jackscrew in the jackscrew hole 82 , the position limit of the lifting frame 8 on the fixing block 42 is released.
