Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7 , the present invention provides a technical solution:

[0031] A suction filtration device for rare earth preparation, comprising:

[0032] The machine body 1 is provided with an observation window 2 for viewing the situation in the cavity 5 in the opening 4, a feeding pipe 3 controlled by a valve, and a vacuum pump 43 for extracting pressure in the cavity 5, and the vacuum pump 43 is connected to the pipeline 42 and installed on the machine body 1;

[0033] The filter plate 9 is connected to the connection groove 6 provided on the body 1 through the opening 4. The connection groove 6 is provided with a clamping groove 7, and the clamping groove 7 is engaged with the clamping block 13 fixed at the bottom of the sealing plate 12, and the sealing plate 12 closes the opening 4;

[0034] Filter plate 27, filter plate 27 is located in opening 4 and above filter plate 1 9, a groove 28 is provided on filter plate 27, and the groove 28 is engaged with a fixed block 30 fixed on the water absorption block 29, filter plate 27 moves in the vertical direction under the action of the adjustment member to squeeze the rare earth solution on filter plate 1 9, and the water absorption block 29 absorbs the liquid passing through filter plate 27; a receiving groove 10 is provided on filter plate 1 9, and filter plate 27 extends into the receiving groove 10 when moving in the vertical direction to squeeze the rare earth solution in the receiving groove 10. Two bottom grooves 11 are provided at the bottom of filter plate 1 9, and protrusions 8 matching the bottom grooves 11 are provided in the connecting groove 6 and the opening 4;

[0035] The crossbar 31 is symmetrically distributed in the opening 4, and the two crossbars 31 extend into the two horizontal holes 33 provided on the pressing block 32, respectively. The pressing block 32 is provided with a through hole 34, and the upper and lower surfaces of the pressing block 32 are provided with a slot 1 35 and a slot 2 36, respectively. A round rod 37 is slidably connected to the through hole 34, and an end block 1 38 is fixed to the upper end of the round rod 37, and an end block 2 40 is fixed to the lower end. The round rod 37 and the end block 1 38 are provided with a vertical hole 39 sleeved on the rotating rod 17, and a spring 41 is sleeved on the round rod 37, and one end of the spring 41 abuts against the end block 1 38, and the other end abuts against the slot 1 35. The spring 41 pushes the end block 1 38 to move upward, so the round rod 37 moves upward until the end block 2 40 fits with the slot 2 36, and at this time, the lower surface of the end block 2 40 is flush with the lower surface of the pressing block 32. Therefore, the bottom of the pressing block 32 cooperates with the second end block 40 to squeeze the water absorbing block 29 until the water absorbed in the water absorbing block 29 is squeezed out, falls into the cavity 5 through the second filter plate 27, and is sucked away by the vacuum pump 43 and the pipeline 42. The first end block 38 is pressed down until the vertical hole 39 is separated from the rotating rod 17, and the pressing block 32 can be pulled out from the body 1, which is convenient for the staff to replace or clean the pressing block 32.

[0036] Specifically, Figure 4 and Figure 5As shown, the adjusting member includes an L-shaped plate 24 fixed on the filter plate 27, a slider 25 is fixed on the side wall of the L-shaped plate 24, and a slide groove 23 slidably connected to the slider 25 is provided in the opening 4, a bent plate 15 is fixed on the machine body 1, and a motor 16 is fixed on the bent plate 15, the motor 16 drives the rotating rod 17 to rotate, the rotating rod 17 is connected to the circular hole 26 provided on the bent plate 15 by threads, and the rotating rod 17 cooperates with the stopper to position the sealing plate 12. The motor 16 drives the rotating rod 17 to move, so that the filter plate 27 moves in the vertical direction, and the filter plate 27 squeezes the rare earth solution in the containing tank 10 when it moves downward, and the filter plate 27 facilitates the moving block 19 to release the positioning of the sealing plate 12 when it moves upward, and the pressing block 32 squeezes the water absorbing block 29, so that the liquid absorbed in the water absorbing block 29 is squeezed out.

[0037] Specifically, Figure 1 and Figure 3 As shown, the limiting member includes a fixing rod 18 fixed between the bent plate 15 and the body 1, the fixing rod 18 is slidably connected with a sliding hole 21 provided on the moving block 19, a screw hole 20 is provided on the fixing rod 18 and is threadedly connected with the rotating rod 17, a cylinder 14 is fixed on the sealing plate 12, and a sleeve hole 22 is provided on the moving block 19 to be sleeved on the cylinder 14. When the moving block 19 moves in the vertical direction, it can limit or release the sealing plate 12, so that the sealing plate 12 can stably exert the sealing effect on the opening 4.

[0038] Specifically, Figure 2 and Figure 4 As shown, the motor 16 drives the rotating rod 17 to rotate, and the L-shaped plate 24 and the moving block 19 both move upward until the sleeve hole 22 of the moving block 19 is separated from the cylinder 14, and the sealing plate 12 can be removed, and the water absorbing block 29 does not contact the pressing block 32. At this time, after the staff removes the sealing plate 12, the filter plate 19 at the opening 4 can be removed to facilitate the subsequent treatment of the rare earth in the containing tank 10. When the motor 16 drives the rotating rod 17 to continue to rotate, the moving block 19 moves up to abut against the bent plate 15. At this time, the water absorbing block 29 is fully squeezed by the pressing block 32, and the pressing block 32 squeezes out the liquid in the water absorbing block 29, and the liquid falls into the cavity 5 through the filter plate 27 to be collected.

[0039] In summary, the valve of the feed pipe 3 provided in this embodiment is opened, and the rare earth solution falls into the receiving tank 10 on the filter plate 9 until the receiving tank 10 is filled. The valve of the feed pipe 3 is closed, and the cavity 5 in the body 1 is in a closed state. The vacuum pump 43 cooperates with the pipeline 42 to extract the air under the filter plate 9, resulting in a pressure difference between the upper and lower parts of the filter plate 9. The filtration of the rare earth solution in the receiving tank 10 is accelerated, and the vacuum pump 43 cooperates with the pipeline 42 to extract the liquid passing through the filter plate 9.

[0040] As the liquid in the rare earth solution continues to pass through the filter plate 1 9, the liquid in the upper layer of the rare earth solution cannot sink easily, and thus falls into the cavity 5 through the filter plate 1 9 and is sucked away by the vacuum pump 43 and the pipe 42. At this time, the motor 16 can be started, and the motor 16 drives the rotating rod 17 to rotate, and the L-shaped plate 24 and the filter plate 2 27 move downward together until the filter plate 2 27 extends into the receiving tank 10. The filter plate 27 squeezes the rare earth solution in the receiving tank 10, so that the liquid in the solution moves upward and passes through the filter plate 27 to be absorbed by the water absorption block 29. In combination with the vacuum pump 43, the rare earth solution in the receiving tank 10 can be filtered more quickly.

[0041] After the rare earth solution in the receiving tank 10 is filtered through the observation window 2, the motor 16 can be controlled to rotate in the opposite direction. At this time, the moving block 19 and the filter plate 27 move upward together until the sleeve hole 22 on the moving block 19 is separated from the cylinder 14, and the sealing plate 12 can be pushed upward until the block 13 is separated from the slot 7. At this time, the sealing plate 12 can be removed from the opening 4. Then the filter plate 19 is lifted up to make the protrusion 8 separate from the bottom slot 11, and the filter plate 19 can be taken out of the body 1. The motor 16 continues to rotate, and the filter plate 27 continues to move upward until the water absorption block 29 is squeezed by the filter plate 27 and the pressing block 32, and the liquid absorbed in the water absorption block 29 is squeezed out, and the liquid falls into the cavity 5 through the filter plate 27, and the vacuum pump 43 cooperates with the pipeline 42 to extract the liquid.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
