Description

Technical Field

[0001] This invention relates to the field of lithium carbonate preparation technology, and specifically to a filtration device for lithium carbonate production. Background Technology

[0002] Lithium carbonate is an inorganic compound and one of the raw materials commonly used in modern industrial production processes. For example, the battery industry needs to use lithium carbonate. With the continuous popularization of electric energy, the market demand for lithium carbonate is also increasing. Lithium carbonate is generally produced by leaching. In the leaching process, the semi-finished product often needs to be filtered. In this process, a filtration device for lithium carbonate production is required.

[0003] Existing filtration devices for lithium carbonate production typically use filter screens for filtration. Since the filter components are usually fixed within the device, frequent cleaning of the filtered impurities is required to ensure smooth subsequent filtration. This cleaning process significantly increases the workload for operators, and sometimes even necessitates stopping the machine for cleaning when there are too many impurities, thus greatly reducing the overall efficiency of the filtration process. Summary of the Invention

[0004] The purpose of this invention is to provide a filtration device for lithium carbonate production, so as to solve the problem that the existing filtration devices for lithium carbonate production are time-consuming and labor-intensive in the process of cleaning impurities during use.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A filtration device for lithium carbonate production includes a square mounting cylinder with through holes on both sides of the bottom of the square mounting cylinder. A three-way pipe is installed at one end of the square mounting cylinder and communicates with the through holes. An installation chamber is installed at the top of the square mounting cylinder, and a surrounding guide cylinder is installed on the outer wall of the installation chamber. A movable cylinder is installed inside the through holes, and a filter plate is installed at the top of the movable cylinder.

[0007] The filter plate has an installation groove on the side near the installation chamber, and a first rack is provided inside the installation groove. Both ends of the bottom of the square installation cylinder are equipped with installation plates, and a first rotating shaft is provided on the end of the installation plate near the square installation cylinder. A gear is installed on the outside of the first rotating shaft.

[0008] The square mounting cylinder is equipped with a drive mechanism for rotating the first rotating shaft.

[0009] Both sides of the installation chamber are evenly provided with trapezoidal grooves, both sides of the top of the surrounding guide cylinder are provided with guide blocks, and the bottom of the guide blocks is provided with sliding grooves. The filter plate is provided with a connecting mechanism for driving the guide blocks to move.

[0010] As a further aspect of the present invention: the surrounding guide cylinder and the square mounting cylinder are fixedly connected by welding, and the bottom of the interior of the surrounding guide cylinder is inclined.

[0011] As a further aspect of the present invention: the cross-sectional shape of the filter plate is trapezoidal, and the cross-sectional area of ​​the filter plate is the same as the cross-sectional area of ​​the movable cylinder.

[0012] As a further aspect of the present invention: the driving mechanism includes a motor, which is installed on one side inside the square mounting cylinder, and the output end of the motor is connected to a reciprocating lead screw, and a second rack is sleeved on the outer side of the reciprocating lead screw.

[0013] As a further aspect of the present invention: the second rack is threadedly connected to the reciprocating lead screw, and the second rack is meshed with the gear.

[0014] As a further aspect of the present invention: the connecting mechanism includes a connecting plate, which is installed through the bottom of the filter plate and through the movable cylinder, and extends into the interior of the slide groove, and a spring is connected between the connecting plate and the guide block.

[0015] As a further aspect of the present invention: the bottom end of the connecting plate is rounded, and the connecting plate and the filter plate are fixedly connected by welding.

[0016] As a further embodiment of the present invention: a partition plate is installed at the middle position of the top of the inner part of the surrounding guide cylinder, a second rotating shaft is passed through one side of the partition plate, and fans are installed on the outer sides of the second rotating shaft near both ends. The second rotating shaft is connected to the reciprocating lead screw through a pulley mechanism, and the pulley mechanism passes through the partition plate.

[0017] As a further aspect of the present invention: the central axis of the fan coincides with the central axis of the second rotating shaft, and the two sets of fans are symmetrically arranged with respect to the longitudinal central axes of the partition plate.

[0018] As a further aspect of the present invention: a first installation window is provided at both ends of the two sides of the installation compartment, and a first dustproof net is installed inside the first installation window; a second installation window is reserved on both sides of the top of the installation compartment, and a second dustproof net is installed inside the second installation window.

[0019] The beneficial effects of this invention are:

[0020] (1) The present invention provides a driving mechanism in a square mounting cylinder and a first rotating shaft and a gear on the mounting plate. The gear and the first rack are meshed. In use, the driving mechanism can drive the movable cylinder to move up and down repeatedly. When the movable cylinder rises, it can drive the filter plate to move upward to the inside of the surrounding guide cylinder.

[0021] (2) The present invention connects the three-way pipe with two sets of through holes, and two sets of movable cylinders are provided on the square mounting cylinder. When in use, the two sets of movable cylinders always move in opposite directions, so that when one set of movable cylinders moves upward to clean the impurities on the filter plate, the other set of filter plates can be located in the corresponding through hole to perform the filtration task, thereby ensuring the filtration efficiency.

[0022] (3) The present invention connects the connecting plate and the guide block with a spring, and the installation chamber is provided with multiple sets of trapezoidal grooves, so that when the filter plate is pushed into the interior of the guide cylinder by the movable cylinder, the filter plate can continuously shake laterally, thereby further ensuring that impurities can be shaken into the interior of the guide cylinder, and ensuring the smooth progress of the filter plate cleaning task.

[0023] (4) The present invention connects the second rotating shaft and the reciprocating screw through a belt pulley mechanism, so that the second rotating shaft and the fan on it can rotate with the reciprocating screw, thereby blowing the impurities in the surrounding guide cylinder further outward, and the inclined surface at the bottom of the surrounding guide cylinder ensures that too many impurities will remain in the surrounding guide cylinder, so that there is always enough space reserved in the surrounding guide cylinder to collect the impurities falling from the filter plate.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Please see Figures 1-8 As shown, a filtration device for lithium carbonate production includes a square mounting cylinder 1. Both sides of the bottom of the square mounting cylinder 1 are provided with through holes 2. A three-way pipe 3 is installed at one end of the square mounting cylinder 1 and is connected to the through hole 2. In use, the end of the three-way pipe 3 away from the square mounting cylinder 1 is connected to the raw material supply equipment, and the raw material enters the interior of the through hole 2 through the three-way pipe 3.

[0037] The top of the square mounting cylinder 1 is equipped with a mounting chamber 4, and the outer wall of the mounting chamber 4 is equipped with a surrounding guide cylinder 5. The inside of the through hole 2 is equipped with a movable cylinder 6, and the top of the movable cylinder 6 is equipped with a filter plate 7. After the raw material enters the inside of the through hole 2, the filter plate 7 can filter the raw material. Impurities remain on the filter plate 7. The raw material flows downward through the filter holes on the filter plate 7 and the hole in the middle of the movable cylinder 6, thereby completing the filtration task.

[0038] The cross-sectional shape of the filter plate 7 is trapezoidal, and the cross-sectional area of ​​the filter plate 7 is the same as that of the movable cylinder 6. The movable cylinder 6 and the filter plate 7 form a relative sliding structure with the through hole 2. Under the action of the corresponding external force, the movable cylinder 6 and the filter plate 7 can slide inside the through hole 2. At the same time, when the filter plate 7 moves to the inside of the surrounding guide cylinder 5, the impurities on the filter plate 7 can roll down along the filter plate 7 and be collected inside the surrounding guide cylinder 5.

[0039] A mounting groove 8 is provided on the side of the filter plate 7 near the mounting chamber 4, and a first rack 9 is provided inside the mounting groove 8. Mounting plates 10 are installed at both ends of the bottom of the square mounting cylinder 1, and a first rotating shaft 11 is provided at the end of the mounting plate 10 near the square mounting cylinder 1. A gear 12 is installed on the outside of the first rotating shaft 11. The first rotating shaft 11 and the mounting plate 10 are connected by bearings. The gear 12 meshes with both sets of first racks 9 simultaneously, so that when the gear 12 rotates, the two sets of movable cylinders 6 can move in opposite directions. When one set of movable cylinders 6 moves upward and pushes the filter plate 7 into the interior surrounding the guide cylinder 5, at this time, the set of movable cylinders... The side of the moving cylinder 6 simultaneously blocks and seals the connection between the corresponding through hole 2 and the three-way pipe 3. The raw material in the three-way pipe 3 flows into another set of through holes 2. At this time, the moving cylinder 6 in the other set of through holes 2 is in the downward movement stroke, so that the connection between the set of through holes 2 and the three-way pipe 3 is not blocked and sealed by the side wall of the moving cylinder 6. The raw material in the three-way pipe 3 can flow into the set of through holes 2 and complete the filtration task through the filter plate 7 in the set of through holes 2 and the moving cylinder 6. When the gear 12 rotates back and forth continuously, the above process can be carried out alternately, thereby continuously completing the filtration task and continuously completing the cleaning task on the filter plate 7.

[0040] It should be noted that the minimum stroke of the movable cylinder 6 will not leave the interior of the through hole 2, and the maximum stroke of the movable cylinder 6 can still maintain the task of sealing the connection between the corresponding through hole 2 and the tee pipe 3.

[0041] The square mounting cylinder 1 is equipped with a drive mechanism for rotating the first rotating shaft 11. The drive mechanism includes a motor 13, which is installed on one side inside the square mounting cylinder 1. The output end of the motor 13 is connected to a reciprocating lead screw 14, and a second rack 15 is sleeved on the outside of the reciprocating lead screw 14. The second rack 15 is threadedly connected to the reciprocating lead screw 14, and the second rack 15 is meshed with a gear 12. The reciprocating lead screw 14 and the square mounting cylinder 1 are connected by a bearing, so that when the motor 13 drives the reciprocating lead screw 14 to rotate, the rotation of the second rack 15 is restricted. The second rack 15 can move laterally back and forth continuously, so that the gear 12 can complete the task of continuous reciprocating rotation, thereby completing the continuous up and down movement of the two sets of movable cylinders 6.

[0042] Example 2

[0043] Based on the above embodiment 1, please refer to Figures 1-8 As shown, trapezoidal grooves 16 are evenly provided on both sides of the installation chamber 4, and guide blocks 17 are provided through both sides surrounding the top of the guide cylinder 5. The bottom of the guide block 17 is provided with a sliding groove 18. The guide block 17 is slidably connected to the guide cylinder 5, and the maximum stroke of the guide block 17 will not be higher than the top of the inside of the guide cylinder 5.

[0044] The filter plate 7 is provided with a connecting mechanism for driving the guide block 17 to move. The connecting mechanism includes a connecting plate 19, which is installed through the bottom of the filter plate 7 and through the movable cylinder 6. The connecting plate 19 extends into the interior of the slide groove 18. A spring 20 is connected between the connecting plate 19 and the guide block 17, so that when the movable cylinder 6 moves up and down, the guide block 17 can move up and down at the same time and perform the guiding task.

[0045] The bottom end of the connecting plate 19 is rounded, and the connecting plate 19 and the filter plate 7 are fixedly connected by welding. The connecting plate 19 is slidably connected to the movable cylinder 6 and the sliding groove 18. In the initial state, the spring 20 is in a stretched state. Therefore, when the filter plate 7 is inside the surrounding guide cylinder 5, during the process of the movable cylinder 6 completing the remaining upward stroke, the connecting plate 19 can be intermittently inserted into the trapezoidal groove 16, so that the filter plate 7 can continuously shake laterally under the elastic action of the spring 20, thereby ensuring that the impurities on the filter plate 7 are shaken off into the surrounding guide cylinder 5.

[0046] It should be noted that the overall shaking amplitude of the filter plate 7 is small, ensuring that the filter plate 7 will not expose the top of the hole in the middle of the movable cylinder 6 during the lateral shaking process. In practical applications, the bottom edge of the filter plate 7 can be set as an arc angle, so that the filter plate 7 can be better reinserted into the through hole 2.

[0047] Example 3

[0048] Based on the above embodiments 1 and 2, please refer to Figures 1-8 As shown, the surrounding guide cylinder 5 and the square mounting cylinder 1 are fixedly connected by welding, and the bottom of the inside of the surrounding guide cylinder 5 is inclined, so that after impurities enter the surrounding guide cylinder 5, they can roll outward along the surrounding guide cylinder 5. In the application process, the surrounding guide cylinder 5 can be further connected to the impurity collection device, so that the impurities rolling down inside the surrounding guide cylinder 5 can be collected by the impurity collection device.

[0049] A partition plate 21 is installed in the middle of the top of the inside of the guide cylinder 5. A second rotating shaft 22 passes through one side of the partition plate 21. Fans 23 are installed on the outer sides of the second rotating shaft 22 near both ends. The second rotating shaft 22 is connected to the reciprocating screw 14 through a pulley mechanism 24, which passes through the partition plate 21. The second rotating shaft 22 is connected to the mounting chamber 4 through a bearing, so that when the reciprocating screw 14 rotates, the second rotating shaft 22 can drive the two sets of fans 23 on it to rotate. A gap is left between the pulley mechanism 24 and the partition plate 21 to ensure that the pulley mechanism 24 can be used normally.

[0050] The central axis of the fan 23 coincides with the central axis of the second rotating shaft 22, and the two sets of fans 23 are symmetrically arranged relative to the longitudinal central axis of the partition plate 21. The two ends of both sides of the installation chamber 4 are provided with a first installation window 25, and a first dustproof net 26 is installed inside the first installation window 25. The two sides of the top of the installation chamber 4 are reserved with a second installation window 27, and a second dustproof net 28 is installed inside the second installation window 27. When the fan 23 rotates, it can take in air through the corresponding second installation window 27 and blow air out through the corresponding first installation window 25. This can be combined with the inclined edge of the bottom of the surrounding guide cylinder 5 to ensure that impurities inside the surrounding guide cylinder 5 roll off. The two sets of fans 23 can ensure that the fans 23 blow air out through the existing fan blade design.

[0051] The working principle of the present invention is as follows: The device is powered by an external power source or a storage battery. The motor 13 is controlled by a controller to start and stop the operation. When in use, the end of the three-way pipe 3 away from the square mounting cylinder 1 is connected to the raw material supply equipment that needs to be filtered, the surrounding guide cylinder 5 is connected to the impurity collection equipment, and the filtered raw material collection equipment is placed below the square mounting cylinder 1.

[0052] Initially, one set of movable cylinders 6 is in the upward stroke, blocking the connection between the corresponding through hole 2 and the three-way pipe 3. The other set of movable cylinders 6 is in the downward stroke, not blocking the connection between the corresponding through hole 2 and the three-way pipe 3. The raw material enters the through hole 2 through the three-way pipe 3, is filtered by the filter plate 7, and falls along the movable cylinder 6. The control motor 13 drives the reciprocating screw 14 to rotate continuously, causing the second rack 15 to move laterally and reciprocating, and the gear 12 to rotate continuously. The two sets of movable cylinders 6 can move in opposite directions simultaneously, allowing them to continuously alternate between the two states, thus continuously completing the filtration task. Meanwhile, when a set of movable cylinders 6 begins its upward stroke after the downward stroke, the set of movable cylinders 6 first blocks the connection between the corresponding through hole 2 and the three-way pipe 3 after moving a certain distance. Then, the filter plate 7 is pushed into the interior of the surrounding guide cylinder 5. Then, the filter plate 7 continues to move upward a certain distance. During this process, the connecting plate 19 will intermittently insert into the corresponding trapezoidal groove 16 under the elastic action of the spring 20, so that the filter plate 7 completes a small-amplitude lateral shaking task. Combined with the shape of the filter plate 7, the impurities on the filter plate 7 can fall fully into the interior of the surrounding guide cylinder 5. Then, the set of movable cylinders 6 begins to descend, and another set of movable cylinders 6 begins to ascend, and the above operation is repeated continuously.

[0053] During the above process, the second rotating shaft 22 will rotate continuously with the rotation of the reciprocating screw 14, so that the fan 23 can rotate continuously. The fan 23 can drive the external air to enter through the corresponding second mounting window 27 and be discharged through the corresponding first mounting window 25, thereby ensuring that impurities can roll into the impurity collection device in conjunction with the inclined edge surrounding the bottom of the guide cylinder 5.

[0054] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
