[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0034] See also Figures 1-10 , the present invention provides the following technical solutions:

[0035] Embodiment 1: In order to solve the problem that it is inconvenient to discharge filter residue in the previous filter press device for rare earth oxide production, the following technical solution is provided, specifically, a filter press device for rare earth oxide production, including a shell 1 and a support 2 arranged on the front and rear sides of the shell 1, the front and rear sides of the shell 1 are connected to the corresponding support 2 by bearing connection, and the inner top end of the shell 1 is installed with a cylinder 4 through a cylinder frame 3, the telescopic end of the cylinder 4 is fixedly connected with 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 shell 1, and the lower surface of the shell 1 is provided with a drainage channel 14 that passes through the filter plate 12, the support 2 is connected to the shell 1 through a slag discharge mechanism, and the slag discharge mechanism includes a slag discharge channel 13 arranged on the lower surface of the shell 1, the slag discharge channel 13 passes through one side of the filter plate 12, and the shell 1 is provided with a liquid inlet 6 that passes through the inner and outer sides thereof, and the height of the liquid inlet 6 is higher than the height of the filter plate 12, so as to facilitate the injection of rare earth oxide into the filter plate 12.

[0036] The slag discharge mechanism also includes a piston chamber 15 arranged on one side of the top of the slag discharge channel 13, and one end of a piston plate 18 is seamlessly slidably connected to the opening of the piston chamber 15, and the end of the piston plate 18 extending into the opening of the piston chamber 15 is evenly provided with a limiting hole 17, and each limiting hole 17 is extended with one end of a corresponding limiting rod 16, the other end of the limiting rod 16 is fixedly connected to the bottom end of the piston chamber 15, and the outer side of each limiting rod 16 is sleeved with a spring 19 whose two ends are respectively connected between the bottom end of the piston chamber 15 and the piston plate 18, and the other end of the piston plate 18 is fixed. A block 20 is connected to block the part where the slag discharge channel 13 and the filter plate 12 pass through. A through hole is opened on the filter plate 12 for passing through the slag discharge channel 13, and the through hole and the block 20 are isosceles terraced structures that match each other. The slag discharge mechanism also includes an air cavity 10 provided on each support 2, and one end of the connecting rod 9 is seamlessly slidably connected to the open end of the air cavity 10. The other ends of the two connecting rods 9 are connected by a shaft rod 7, and the shaft rod 7 is fixedly connected to one side of the shell 1. A handle 5 is installed on the other side of the shell 1. The inner bottom end of the air cavity 10 is connected to the air guide pipe. 8 is connected to the piston chamber 15, and rare earth oxides are injected into the filter plate 12 through the liquid inlet hole 6. Due to the action of gravity, some rare earth oxides are filtered and discharged from the drainage channel 14. Then, the cylinder 4 controls the pressure plate 11 to move downward, so that the pressure plate 11 and the filter plate 12 are squeezed, thereby filtering the remaining rare earth oxides. The liquid part will be discharged from the drainage channel 14 under the action of the pressure filtration. The material remaining on the filter plate 12 is the filter residue. When the filter residue on the filter plate 12 needs to be discharged, the handle 5 can be grasped and the housing 1 can be driven to rotate a certain angle. When the shell 1 rotates relative to the support 2, the connecting rod 9 will move outward in the air cavity 10, thereby generating negative pressure in the air cavity 10. After the negative pressure is generated in the air cavity 10, the gas in the piston cavity 15 will be sucked through the air guide pipe 8, thereby causing the piston plate 18 to move into the piston cavity 15, thereby driving the blocking block 20 to move synchronously. At this time, the top of the filter plate 12 will be connected to the slag discharge channel 13. Since the shell 1 is tilted, the filter plate 12 arranged therein will also be tilted, which will help the filter residue on the upper surface of the filter plate 12 fall into the slag discharge channel 13 and be discharged from the slag discharge channel 13.

[0037] The air cavity 10 and the connecting rod 9 are both arc-shaped, and the centers of the circles of the two are located at the rotation center of the shell 1. The pressure plate 11 and the filter plate 12 are both quadrangular pyramid structures.

[0038] Example 2: In order to solve the problem that the structure of the filter press device for shaking rare earth oxides in the past can only shake the rare earth oxides but does not have other functions, the following technical solution is provided. Specifically, the telescopic end of the cylinder 4 is connected to the filter plate 12 through a vibration mechanism, and the vibration mechanism includes a mounting groove 21 arranged on the inner side of the shell 1.

[0039] The vibration mechanism also includes a limit bar 22 installed in the mounting groove 21, and the limit bar 22 is movably arranged through the driven gear plate 23. The mounting groove 21 is connected to the opening position bearing of the inner side of the shell 1, and the gear 24 is connected to the telescopic end of the cylinder 4 through the top frame 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 both sides of the filter plate 12, and the interior of each built-in cavity 27 is slidably connected to a vibration plate 29, and 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 mounting groove 21 through two symmetrical protrusions. The vibration plate 29 is connected to the mounting groove 21 through two protrusions. The cylinder 4 is connected to 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 top 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. The driven tooth plate 23 can continuously squeeze the toggle block 30 during the movement, so that the filter plate 12 can vibrate through the elastic sheet 28 and the vibration plate 29. In the process of generating vibration, the filter plate 12 can shake the rare earth oxides thereon, which is conducive to 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 is 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 driven tooth plate 23 at the corresponding position, so that the teeth on the driven tooth plate 23 are in continuous 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 those skilled in the art.

[0042] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
