[0054] The longitudinal shaking assembly 10 includes a large synchronous wheel 101, which is fixed on the coupling of the servo motor 71 near the cam frame 84, and the large synchronous wheel 101 is transmission-connected with a directional wheel 103 that rotates with the fixed frame 3 on all sides. The large synchronous wheel 101 first cooperates with the four groups of small synchronous wheels 102 in the four groups of directional wheels 103 through four groups of small synchronous wheels, and the large synchronous wheel 101 is transmission-connected with the small synchronous wheels 102 on all sides away from the directional wheels 103 through a synchronous belt transmission.

[0056] like Fig.15 As shown, after the lepidolite concentrate powder is filtered, it is mostly necessary to manually transport the filtered lepidolite concentrate powder, and the filtered lepidolite concentrate powder cannot be quickly transported and processed in time, resulting in work waiting. A feeding assembly 12 is provided at the bottom of the filter box 6, and the feeding assembly 12 includes a lower hopper 121, and the lower hopper 121 is connected to the bottom of the filter box 6, and the bottom end of the lower hopper 121 is connected to a feeding barrel 122, and the lepidolite concentrate powder after the horizontal and vertical dynamic filtration is discharged into the feeding barrel 122, waiting for the conveying operation;

One group of long rods 104 drives the second slave bevel gear 125 to rotate through the second main bevel gear 124, and the second slave bevel gear 125 conveys the filtered lithium mica concentrate powder through the feeding auger 126 for unloading operations, which is more efficient and avoids work waiting.

[0058] Specifically, the working principle of the filtering device for lithium mica concentrate powder is as follows: first, the lithium mica concentrate powder to be filtered is poured into the guide rack 2 through the upper hopper 1, and then the servo motor 71 is controlled to start and drive the guide head 72 and the guide leaf 73 to rotate synchronously. The falling lithium mica concentrate powder first falls into the bottom of the inner cavity of the guide rack 2 under the diversion effect of the guide head 72. At this time, the four groups of first solenoid valves 74 are controlled to open synchronously, and the lithium mica concentrate powder is then rotated by the guide leaf 73 to guide the material into the four groups of first telescopic tubes 76, and after the powder flow is detected by the four groups of first powder flowmeters 75, it passes through the four groups of barrel covers 5 and falls into the four groups of filter barrels 4;

[0059] After the lithium mica concentrate powder falls into the four groups of filter cartridges 4, the servo motor 71 drives the guide head 72 and the guide leaf 73 to rotate, and also drives the cam frame 84 to rotate synchronously. The raised end of the cam frame 84 drives the four groups of push rod frames 85 to push synchronously outward in the four groups of sliding sleeves 83, and stretches the four groups of return springs 86. The four groups of limiting slide grooves 81 and the limiting slide seat 82 provide sliding support compensation for the four groups of filter cartridges 4. Then, the four groups of push rod frames 85 that are pushed outward synchronously drive the four groups of filter cartridges 4 to push outward synchronously. On the contrary, when the four groups of push rod frames 85 slide to the recessed end of the cam frame 84, the four groups of return springs 86 lose their thrust and shrink inward. Under the action of the return elastic force of the four groups of return springs 86, the four groups of filter cartridges 4 are driven to shrink and reset synchronously inward through the four groups of push rod frames 85. In this way, the four groups of push rod frames 85 drive the four groups of filter cartridges 4 to shake back and forth in the horizontal direction.

[0060] The four groups of filter cartridges 4 that shake back and forth in the horizontal direction drive the lithium mica concentrate powder inside to shake on the first filter frame 91. At the same time, the driving circular gears 93 on the four groups of filter cartridges 4 mesh back and forth on the teeth of the four groups of rack frames 92, forcing the four groups of driving circular gears 93 to drive the four groups of spoiler blades 95 and the guide blades 96 to reciprocate in the four groups of filter cartridges 4 through the four groups of rotating shafts 94 and generate wind force. The wind force generated by the four groups of spoiler blades 95 will disturb the lithium mica concentrate powder falling into the four groups of filter cartridges 4 downward to In the filtering area of ​​the first filter rack 91, the wind force generated by the guide blades 96 guides the lithium mica concentrate powder filtered by the first filter rack 91 to the second telescopic tube 20 area, and at the same time, the four sets of rotating shafts 94 also drive the four sets of cleaning strips 13, the upper scraping strips 14 and the lower scraping strips 15 to rotate in the positive and negative directions, and the four sets of cleaning strips 13 rotate to clean the lithium mica concentrate powder blocked on the first filter rack 91, and at the same time, the four sets of upper scraping strips 14 and the lower scraping strips 15 scrape the lithium mica concentrate powder adhered to the inner wall of the four sets of four filter cylinders 4;

[0061] After the lithium mica concentrate powder in the four groups of filter cartridges 4 completes the horizontal dynamic filtration operation, the four groups of second solenoid valves 18 are controlled to open synchronously, and under the action of the four groups of guide blades 96, the powder falls into the filter box 6 through the four groups of second telescopic tubes 20, and the powder flow rate is detected by the four groups of second powder flow meters 19. The servo motor 71 drives the cam frame 84 while also driving the large synchronous wheel 101 to rotate synchronously. The large synchronous wheel 101 drives the four groups of small synchronous wheels 102 to rotate synchronously through the synchronous belt under the limited transmission cooperation of the four groups of directional wheels 103. The four groups of small synchronous wheels 102 drive the four groups of first main bevel gears 105 to rotate through the four groups of long rods 104, and the four groups of first main bevel gears 105 drive the four groups of first slave bevel gears 106 to rotate synchronously;

[0062] The four groups of first bevel gears 106 rotating synchronously drive the four groups of cams 111 to rotate accordingly, and the four groups of T-shaped slide rails 112 and the T-shaped slide rail blocks 113 provide sliding support compensation for the second filter rack 114. The four groups of synchronously rotating cams 111 rotate in the sliding grooves 116 on the four groups of embedded seats 115. When the raised ends of the four groups of cams 111 rotate to the sliding grooves 116 area on the four groups of embedded seats 115, the four groups of cams 111 drive the second filter rack 114 to slide upward in the filter box 6 through the four groups of embedded seats 115. On the contrary, when the other end of the four-group cam 111 rotates to the sliding groove 116 area on the four-group embedded seat 115, under the gravity of the lithium mica concentrate powder on the second filter frame 114, the four-group embedded seat 115 on the second filter frame 114 is forced to slide downward in the filter box 6 following the four-group cam 111, and the four-group cam 111 drives the second filter frame 114 to shake longitudinally in the filter box 6 through the four-group embedded seat 115, and completes the longitudinal dynamic filtering operation of the lithium mica concentrate powder in the filter box 6;

[0063] After the lithium mica concentrate powder in the filter box 6 completes the longitudinal dynamic filtration operation, it falls into the front end space of the feeding barrel 122 through the lower hopper 121. At the same time, one group of rotating long rods 104 drives the short rod 123 to rotate accordingly, and the short rod 123 drives the second main bevel gear 124 to rotate, and the second main bevel gear 124 drives the second slave bevel gear 125 to rotate accordingly, and the second slave bevel gear 125 drives the feeding auger 126 to rotate in the feeding barrel 122. The rotating feeding auger 126 transports the lithium mica concentrate powder that has completed the filtration operation and falls into the front end space of the feeding barrel 122 forward to a predetermined position, and the horizontal dynamic filtration, longitudinal dynamic filtration and transportation of the lithium mica concentrate powder are carried out simultaneously.

[0064] It should be noted that the specific model and specifications of the servo motor 71 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
