Description

Technical Field

[0001] The invention relates to the technical field of lithium carbonate filtration, in particular to a crude lithium carbonate filtration device. Background Art

[0002] Crude lithium carbonate is a raw product containing a relatively high level of lithium carbonate. Due to the important application value of lithium carbonate in industries such as lithium batteries, glass manufacturing, pharmaceuticals and ceramics, crude lithium carbonate usually needs to undergo further refining and processing steps to improve its purity and quality so that it meets the requirements of specific applications. During further processing, crude lithium carbonate can be purified and refined through chemical treatment, dissolution, precipitation, filtration, crystallization and other methods to ultimately obtain a high-purity lithium carbonate product.

[0003] Filtration is an important step in the purification process of lithium carbonate. Usually, multiple filters with different pore sizes are used to filter the crude lithium carbonate in sequence to finally obtain a high-purity lithium carbonate product. In existing filtration devices, the filter is usually fixedly installed inside the filter container. After the filtration is completed, it is inconvenient to clean the impurities on the filter, so the residual impurities affect the next filtration. In addition, during the cleaning process, many impurities are stuck in the filter holes. In the existing technology, the filter is usually flushed with a brush or high-pressure water, but the impurities stuck in the filter holes are difficult to clean. Summary of the Invention

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific examples.

[0026] like Figure 1 、 Figure 2 、 Figure 3As shown, a lithium carbonate crude product filtering device includes a filter tank 1, a movable mechanism 2 is provided inside the filter tank 1, and the movable mechanism 2 includes a plurality of filter screens 201.

The movable mechanism 2 includes a mounting ring 202, a block 203, a positioning rod 204 and a driving assembly. The plurality of filter screens 201 are arranged from top to bottom inside the filter tank 1.

The inner wall of the filter tank 1 is provided with multiple annular grooves 209 that cooperate with the clamping blocks 203. The inner wall of the filter tank 1 is provided with strip grooves that cooperate with the positioning rod 204. The strip grooves and the annular grooves 209 are connected. The apertures of the multiple filter screens 201 gradually decrease from top to bottom, thereby filtering impurities of different sizes.

[0027] A plurality of filter screens 201 are used to filter the crude lithium carbonate. Impurities remain on the filter screens 201 after filtration. Then the driving assembly is started to drive the positioning rod 204 to move in a direction away from the filter tank 1 until all the filter screens 201 are moved out of the filter tank 1. Then the cleaning mechanism 5 is used to clean the impurities on the surface of the filter screen 201. The annular groove 209 and the block 203 are cooperated, and the strip groove and the positioning rod 204 are cooperated, so as to realize the installation of multiple filter screens 201, the mounting ring 202 and the block 203. At the same time, it is also convenient to quickly disassemble the filter screen 201, and then clean the impurities remaining on the filter screen 201.

[0028] like Figure 3 As shown, the driving assembly includes a moving rod 205, a first motor 206, a fixed rail 207 and a screw rod 208. The fixed rail 207 is fixedly connected to the outer wall of the filter tank 1 in a left-right symmetrical manner. The moving rod 205 is slidably connected inside the fixed rail 207. The screw rod 208 is rotatably connected inside the fixed rail 207 and is threadedly connected to the moving rod 205. The first motor 206 is installed at the lower end of the fixed rail 207. The moving rod 205 is fixedly connected to the positioning rod 204.

[0029] The driving assembly is provided to drive the positioning rod 204 to move, thereby driving the mounting ring 202 fixedly connected to the positioning rod 204 and the filter 201 to move synchronously, and moving the filter 201 out of the filter tank 1 for easy cleaning. The specific steps are: first start the first motor 206 to drive the screw rod 208 to rotate, and the screw rod 208 further drives the moving rod 205 threadedly connected thereto to move in the fixed rail 207, and the moving rod 205 drives the positioning rod 204 fixedly connected thereto to move, and finally drives the filter 201 to move out of the filter tank 1.

[0030] like Figure 4 、 Figure 5 As shown, the cleaning mechanism 5 is located above the filter tank 1, and the number of cleaning mechanisms 5 corresponds to the filter screen 201, and the cleaning mechanisms 5 are arranged on the left and right sides of the filter tank 1. A reciprocating moving component 3 for driving the cleaning mechanism 5 is also provided above the filter tank 1, and the reciprocating moving component 3 includes a transmission box 301, a second motor 302, a moving frame 303, a rack 304 and an incomplete gear 305. The transmission box 301 is arranged above the filter tank 1, and the second motor 302 is installed on the upper surface of the transmission box 301. The incomplete gear 305 is rotatably connected to the inside of the transmission box 301, and the output end of the second motor 302 is fixedly connected to the incomplete gear 305. The moving frame 303 is slidably connected to the inside of the transmission box 301, and the rack 304 is fixedly connected to the opposite inner wall of the moving frame 303. The incomplete gear 305 and the rack 304 are engaged.

[0031] The reciprocating assembly 3 is used to drive the cleaning mechanism 5 to move. When the filter 201 needs to be cleaned, the second motor 302 is started to drive the incomplete gear 305 to rotate, and the incomplete gear 305 and the rack 304 are engaged, thereby driving the moving frame 303 to move. Since the incomplete gear 305 and the two racks 304 on the moving frame 303 are alternately engaged, the moving frame 303 moves back and forth, thereby moving the cleaning mechanism 5 to the top of the filter 201 or away from the filter 201. When the filter 201 rises, the cleaning mechanism 5 moves away from the filter 201. When the filter 201 reaches the specified position, the cleaning mechanism 5 moves to the top of the filter 201, thereby cleaning the filter 201.

[0032] like Figure 6As shown, the movable frame 303 is fixedly connected to a connecting rod 6, and a flapping assembly 4 is provided on the connecting rod 6. The flapping assembly 4 is used to flap the filter 201. The flapping assembly 4 includes a third motor 401, a disc 402, a fixed rod 403, a push rod 404, a first spring 405, a mounting plate 406 and a bump 407. The third motor 401 is mounted on the side wall of the connecting rod 6 through a motor seat. The output end of the third motor 401 is fixedly connected to the disc 402. The fixing rod 403 is fixedly connected to the surface of the disc 402, the push rod 404 is rotatably connected to the fixing rod 403, the end of the push rod 404 away from the fixing rod 403 is rotatably connected to the mounting plate 406, the mounting plate 406 is slidably connected to the connecting rod 6, the first spring 405 is fixedly connected to the inside of the connecting rod 6 and fixedly connected to the mounting plate 406, and the plurality of protrusions 407 are fixedly connected to the surface of the mounting plate 406 in a square shape, and the protrusions 407 cooperate with the filter 201.

[0033] The provided beating component 4 is used to beat the filter 201 to loosen impurities stuck in the mesh of the filter 201, thereby facilitating the next cleaning of the cleaning mechanism 5. The specific steps are: first start the third motor 401 to drive the disc 402 to rotate, and the fixed rod 403 fixed on the disc 402 rotates synchronously, and the fixed rod 403 further drives the push rod 404 to rotate, and the push rod 404 finally drives the mounting plate 406 to move up and down, and the protrusion 407 fixed on the mounting plate 406 beats the bottom of the filter 201, thereby driving the filter 201 to vibrate and loosen impurities stuck in the mesh of the filter 201, thereby facilitating the next cleaning of the cleaning mechanism 5. The provided first spring 405 has the functions of buffering and rebounding.

[0034] like Figure 7 、 Figure 8 As shown, the cleaning mechanism 5 includes a square plate 501, a hydraulic cylinder 502, a sliding box 503, a brush plate 504, an arc groove 505 and a limit block 506. The square plate 501 is fixedly connected to the surface of the connecting rod 6, the hydraulic cylinder 502 is slidably connected to the upper surface of the transmission box 301, the surface of the transmission box 301 is fixedly connected to the limit rail, the hydraulic cylinder 502 is slidably connected in the limit rail, the output end of the hydraulic cylinder 502 is slidably connected to the surface of the sliding box 503, the sliding box 503 is provided with two, the two sliding boxes 503 are slidably connected back and forth, the brush plate 504 is slidably connected in the sliding box 503, the surface of the brush plate 504 is provided with bristles, the arc groove 505 is opened on the surface of the square plate 501 and cooperates with the limit block 506, the limit block 506 is slidably connected in the arc groove 505, and the limit block 506 and the sliding box 503 are slidably connected.

[0035] After the flapping component 4 finishes flapping the filter screen 201, the hydraulic cylinder 502 is started to push the sliding box 503 slidably connected thereto to move. Since the two sliding boxes 503 are slidably connected, the two sliding boxes 503 move synchronously. At the same time, due to the action of the limiting blocks 506 and the arc-shaped grooves 505, the two sliding boxes 503 move away from or close to each other. When the two limiting blocks 506 move away from each other, the two sliding boxes 503 are driven to move away from each other. When the two limiting blocks 506 move close to each other, the two sliding boxes 503 are driven to move close to each other. The two sliding boxes 503 move away from or close to each other to change the total length of the two sliding boxes 503. The total length of the brush plate 504 slidably connected in the sliding box 503 can adapt to the filter screen 201, that is, the length change from the edge of the filter screen 201 to the center of the circle and then from the center of the circle to the edge. The bristles provided on the brush plate 504 clean the impurities on the surface of the filter screen 201.

[0036] As Figure 8 shown, a square cavity is opened inside the sliding box 503. A second spring 7 is fixedly connected inside the square cavity. The second spring 7 and the brush plate 504 are fixedly connected. A square groove 8 is opened at the bottom of the sliding box 503. The limiting block 506 is slidably connected in the square groove 8.

[0037] The provided second spring 7 is used to buffer and connect the brush plate 504. Thus, when the brush plate 504 cleans the impurities on the filter screen 201, under the action of the second spring 7, the brush plate 504 can elastically contact the filter screen 201, and thus the filter screen 201 will not be damaged.

[0038] As Figure 1 shown, a plug board 9 is fixedly connected to the surface of one of the sliding boxes 503. A slot matching with the plug board 9 is opened on the surface of the other sliding box 503. Through the cooperation of the plug board 9 and the slot, the two sliding boxes 503 are connected together to form a whole. At the same time, the two sliding boxes 503 can slide relative to each other. A U-shaped plate 10 is fixedly connected between the two transmission boxes 301. A support column 11 is fixedly connected to the bottom of the U-shaped plate 10.

[0039] During the working process, after the filtration is completed, the driving component is used to take out multiple filter screens 201. The provided mounting rings 202, clamping blocks 203 and positioning rods 204 connect the multiple filter screens 201 into a whole. The annular groove 209 and the strip-shaped groove are used for installation, so as to facilitate installation and disassembly. Then, the flapping component 4 is used to loosen the impurities stuck on the filter screen 201, and then the cleaning mechanism 5 is used to wash its surface.
