The opening position bearing that passes through the mounting groove and the inner side of the shell is connected to a gear. The telescopic end of the cylinder is connected to the active gear plate through a support frame.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-10 , the present invention provides the following technical solutions:

[0035] Example 1: To solve the problem that the filter press device for rare earth oxide production in the past was not convenient for discharging filter residue, the following technical solution is provided. Specifically, a filter press device for rare earth oxide production includes a housing 1 and supports 2 provided on both the front and rear sides of the housing 1. Both the front and rear sides of the housing 1 are connected to the corresponding supports 2 by means of bearing connections. And a cylinder 4 is installed at the inner top end of the housing 1 through a cylinder frame 3. The telescopic end of the cylinder 4 is fixedly connected to a pressure plate 11. And a filter plate 12 is correspondingly arranged below the pressure plate 11. The filter plate 12 is installed inside the housing 1. And a liquid discharge channel 14 penetrating through to the filter plate 12 is provided on the lower surface of the housing 1. The support 2 is connected to the housing 1 through a slag discharge mechanism. And the slag discharge mechanism includes a slag discharge channel 13 provided on the lower surface of the housing 1. The slag discharge channel 13 penetrates through to one side of the filter plate 12. A liquid inlet hole 6 penetrating through the inner and outer sides of the housing 1 is provided on the housing 1. The height of the liquid inlet hole 6 is higher than the height of the filter plate 12, which is convenient for injecting rare earth oxide onto the filter plate 12.

[0036] The slag discharging mechanism further includes a piston chamber 15 arranged on one side at the top end of the slag discharging passage 13. One end of a piston plate 18 is slidably and seamlessly connected within the opening of the piston chamber 15. A plurality of limiting holes 17 are evenly arranged at the end of the piston plate 18 extending into the opening of the piston chamber 15. One end of a corresponding limiting rod 16 extends into each limiting hole 17. The other end of the limiting rod 16 is fixedly connected to the bottom end within the piston chamber 15. A spring 19 is sleeved outside each limiting rod 16, with both ends respectively connected between the bottom end within the piston chamber 15 and the piston plate 18. The other end of the piston plate 18 is fixedly connected with a plug 20 for blocking the part where the slag discharging passage 13 communicates with the filter plate 12. Through holes are formed on the filter plate 12 for communicating with the slag discharging passage 13. The through holes and the plug 20 are in an isosceles trapezoid structure that fits each other. The slag discharging mechanism further includes an air chamber 10 arranged on each support 2. One end of a linkage rod 9 is slidably and seamlessly connected within the opening end of the air chamber 10. The other ends of the two linkage rods 9 are connected through a shaft rod 7, and the shaft rod 7 is fixedly connected to one side of the housing 1. A handle 5 is installed on the other side of the housing 1. The bottom end within the air chamber 10 is connected to the piston chamber 15 through a guide air pipe 8. Rare earth oxides are injected onto the filter plate 12 through the liquid inlet hole 6. Due to the action of gravity, part of the rare earth oxides will be filtered and discharged through the liquid discharging passage 14. Then, the pressing plate 11 is controlled to move downward by the air cylinder 4, so that the pressing plate 11 presses against the filter plate 12, thereby performing pressure filtration on the remaining part of the rare earth oxides. The liquid part will be discharged through the liquid discharging passage 14 under the action of pressure filtration. The substances remaining on the filter plate 12 are filter residues. When it is necessary to discharge the filter residues on the filter plate 12, the handle 5 can be grasped and the housing 1 can be driven to rotate by a certain angle. When the housing 1 rotates relative to the support 2, the linkage rod 9 will move outward within the air chamber 10, thereby generating negative pressure within the air chamber 10. After negative pressure is generated within the air chamber 10, the gas within the piston chamber 15 will be sucked through the guide air pipe 8, thereby causing the piston plate 18 to move into the piston chamber 15, and further driving the plug 20 to move synchronously. At this time, the upper part of the filter plate 12 will be communicated with the slag discharging passage 13. Since the housing 1 is inclined, the filter plate 12 arranged therein will also be inclined, which helps the filter residues on the upper surface of the filter plate 12 to fall into the slag discharging passage 13 and be discharged from the slag discharging passage 13.

[0037] Both the air chamber 10 and the linkage rod 9 are arc-shaped, and the centers of the two are located at the rotation center of the housing 1. Both the pressing plate 11 and the filter plate 12 are in a frustum of a pyramid structure.

[0038] Embodiment 2: To solve the problem that the structure for shaking rare earth oxides on the pressure filtration device used in the production of rare earth oxides in the past can only shake the rare earth oxides and does not have other functions, the following technical solution is provided. Specifically, the telescopic end of the air cylinder 4 is connected to the filter plate 12 through a vibration mechanism, and the vibration mechanism includes an installation groove 21 arranged inside the housing 1.

[0039] The vibration mechanism also includes a limit bar 22 installed in the installation groove 21, and the limit bar 22 movably penetrates the driven gear plate 23. The opening position bearing that passes through the installation groove 21 and the inner side of the shell 1 is connected to a gear 24. The telescopic end of the cylinder 4 is connected to the active gear plate 25 through the top support 26. The active gear plate 25 and the driven gear plate 23 are respectively meshed and connected to the two sides of the corresponding gear 24, so that the movement of the telescopic end of the cylinder 4 drives the driven gear plate 23 to move in the opposite direction. The vibration mechanism also includes built-in cavities 27 arranged inside the two sides of the filter plate 12, and each built-in cavity 27 is slidably connected to a vibration plate 29. An elastic sheet 28 is installed between one side of the vibration plate 29 and the inner side of the corresponding built-in cavity 27, and the other side of the vibration plate 29 is movably penetrated into the installation groove 21 through two symmetrical protrusions. The vibration plate 29 is connected to the inner side of the corresponding built-in cavity 27 through two protrusions. The cylinder 4 is connected with the corresponding toggle block 30. During the extension and retraction process, the telescopic end of the cylinder 4 drives the active tooth plate 25 to move synchronously through the support frame 26. Since the active tooth plate 25 and the driven tooth plate 23 are respectively meshed and connected to the two sides of the gear 24, the telescopic end of the cylinder 4 can drive the driven tooth plate 23 to move in the opposite direction during the movement. During the movement, the driven tooth plate 23 can continuously squeeze the toggle block 30, so that the filter plate 12 can be vibrated through the elastic sheet 28 and the vibration plate 29. During the vibration process, the filter plate 12 can shake the rare earth oxides thereon, which is helpful for the filtration of the rare earth oxides. In the process of discharging the filter residue, the filter residue adhering to the filter plate 12 can be shaken off, so that the filter residue on the filter plate 12 can be discharged more thoroughly, which is conducive to ensuring the filtration effect of the filter plate 12 and the pressure plate 11.

[0040] The toggle block 30 is provided with teeth, and the teeth on the toggle block 30 correspond to the teeth on the corresponding position of the driven tooth plate 23, so that the teeth on the driven tooth plate 23 are in constant contact with the teeth on the toggle block 30 and the elastic sheet 28 cooperates to make the filter plate 12 vibrate.

[0041] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
