Description

Technical Field

[0001] This utility model belongs to the field of filtration devices, specifically relating to an integrated carbonized wire filtration device. Background Technology

[0002] In the production of battery-grade lithium carbonate, the purification process of industrial-grade lithium carbonate is a crucial step in ensuring product quality. This process requires precise operation through multiple steps: first, industrial-grade Li₂CO₃ is reacted with CO₂ gas in a reactor to convert it into LiHCO₃ solution under specific process conditions; then, impurities such as Ca, Mg, and B are removed by resin ion exchange adsorption; finally, battery-grade Li₂CO₃ is obtained through pyrolysis, while the recovered CO₂ gas is recycled for the generation of LiHCO₃ solution, and the saturated resin can be reused after desorption with hydrochloric acid, etc.

[0003] In this purification process, the purification and filtration of the LiHCO3 solution is a crucial step in ensuring the purity of the final product. To reduce process costs and improve purification efficiency, a filtration device must be used to remove large particulate impurities before the LiHCO3 solution enters the resin ion adsorption. However, existing filtration devices used in this process often have the following problems: when replacing the filter cartridge for different stages of the solution (such as the initial solution containing impurities, the solution after ion exchange), it is necessary to disassemble many external pipelines and fixed components, which is cumbersome and time-consuming, affecting the continuity of production; the overall structure of the device is loosely laid out, occupies a large space, and is not conducive to the construction of a compact production system; at the same time, the filtration efficiency of the filtration device is not good and needs further improvement. Utility Model Content

[0004] To overcome the problems of cumbersome filter replacement, insufficient structural compactness, and poor filtration efficiency in existing filtration devices, an integrated carbonized wire filtration device is proposed.

[0005] The technical solution of this utility model is as follows: an integrated carbonized wire filter device, including a filter box, an inlet pipe and an outlet pipe are fixedly connected through the filter box, the upper end of the filter box is open, a first sleeve and a second sleeve are fixedly connected to the bottom surface of the inner wall of the filter box, the first sleeve and the second sleeve are corresponding to each other, one end of the first purification tube is threadedly installed on the inner wall of the first sleeve near the second sleeve, one end of the second purification tube is slidably provided on the inner wall of the second sleeve near the first sleeve, and the other end of the second purification tube and the other end of the first purification tube are in contact with each other; A sealing sleeve is fixed to the outer wall of the second purification tube near the first purification tube, and the inner wall of the sealing sleeve is in contact with the outer wall of the first purification tube near the second purification tube. The sealing sleeve is equipped with a limiting mechanism, and the limiting mechanism is equipped with a locking mechanism for locking the limiting mechanism on the filter box; One end of the second connecting pipe is fixed to the liquid outlet end of the first sleeve, and the other end of the second connecting pipe is connected to one end of the adsorption pipe. The other end of the adsorption pipe is fixed to the liquid inlet end of the water outlet pipe. One end of the first connecting pipe is fixed to the liquid outlet end of the water inlet pipe, and the other end of the first connecting pipe is fixed to the liquid inlet end of the second sleeve.

[0006] Furthermore, a cover plate is placed on the upper part of the filter box, and a limit block is fixed to the lower end of the cover plate. The side wall of the limit block is in contact with the inner wall of the filter box.

[0007] Furthermore, the limiting mechanism includes a support block fixed to the side wall of the sealing sleeve, a through hole opened through the support block, and a first hinge seat fixed to the upper end of the support block. Guide rods are fixed to both sides of the inner wall of the filter box. The inner wall of the through hole and the side wall of the guide rod are in contact with each other, and the side wall of the support block is in contact with one side wall of the filter box.

[0008] Furthermore, the locking mechanism includes a first bolt threaded onto the first hinge seat, one end of the first bolt passing through the first hinge seat and the wall of the filter box and extending to the outside of the filter box, and a first nut threaded onto the outer wall of the first bolt located outside the filter box.

[0009] Furthermore, a sound insulation plate is fixed to the bottom surface of the inner wall of the filter box, and the sound insulation plate is located between the first sleeve and the adsorption tube.

[0010] Furthermore, a filter element is fixed to the inner wall of the first purification tube, and a wire mesh is fixed to the inner wall of the second purification tube.

[0011] Furthermore, the inner wall of the filter box is provided with two mutually symmetrical positioning mechanisms. The positioning mechanism includes a fixed block fixed to the side wall of the guide rod, a second hinge fixed to the upper end of the fixed block, a rotating block rotatably mounted on the second hinge, and a second bolt threaded on the rotating block. One end of the second bolt passes through the wall of the filter box and extends to the outside of the filter box. A second nut is threaded on the outer wall of the second bolt located outside the filter box.

[0012] Furthermore, the inner wall of the adsorption tube is fixed with equidistantly distributed activated carbon rings, which are annular in shape and have an inner diameter of less than ten centimeters.

[0013] The beneficial effects of this utility model are: 1. This device features a structure design where the first purification tube is threadedly connected to the first sleeve, and the second purification tube is slidably fitted to the second sleeve. Combined with a limiting mechanism and a locking mechanism, it enables quick assembly and disassembly. When the filter element needs to be replaced, first loosen the first nut and first bolt in the locking mechanism, allowing the support block of the limiting mechanism to slide on the guide rod. This causes the sealing sleeve and the second purification tube connected to it to move away from the first purification tube, releasing their contact. Then, rotate the first purification tube to unscrew it from the threaded connection of the first sleeve, allowing the first purification tube to be removed for filter element replacement. During installation, reverse the above steps. The sealing sleeve and the outer wall of the first purification tube ensure a tight seal, and the locking mechanism secures the limiting mechanism. The entire process does not require disassembling too many parts, significantly simplifying the replacement process. 2. This device integrates the first purification tube, the second purification tube, and the adsorption tube inside the filter box. The first connecting tube and the second connecting tube realize the orderly connection of each component with the inlet and outlet water pipes, reducing the exposure and space occupation of external pipelines. At the same time, the guide rod on the inner wall of the filter box provides support and guidance for the limiting mechanism, making the layout of each component more compact in the limited space. The limiting block at the lower end of the cover plate fits against the inner wall of the filter box, further improving the compactness and stability of the overall structure and avoiding space waste caused by component shaking. 3. The fluid enters the second purification pipe from the inlet pipe via the first connecting pipe. It undergoes preliminary filtration through the wire mesh inside the second purification pipe to remove larger particles of impurities. Then, it flows into the first purification pipe, where it undergoes deep filtration through the filter element inside. The filtered fluid then enters the adsorption pipe through the second connecting pipe, where it is purified by adsorption using the activated carbon rings inside the adsorption pipe. Finally, it is discharged through the outlet pipe. This step-by-step purification process improves the filtration effect. Furthermore, the close fit design of the first and second purification pipes and the sealing effect of the sealing sleeve reduce fluid leakage and short circuits, ensuring the stability of filtration efficiency. In addition, the sound insulation board inside the filter box reduces the noise generated by water flow impact, providing a stable environment for high-efficiency filtration.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1: Please refer to Figures 1-7 An integrated carbonized wire filter device includes an integrated carbonized wire filter device, including a filter box 1. An inlet pipe 2 and an outlet pipe 3 are fixedly connected through the filter box 1. The upper end of the filter box 1 is open. A first sleeve 5 and a second sleeve 8 are fixedly connected to the bottom surface of the inner wall of the filter box 1. The first sleeve 5 and the second sleeve 8 correspond to each other. One end of a first purification pipe 6 is threadedly installed on the inner wall of the first sleeve 5 near the second sleeve 8. One end of a second purification pipe 9 is slidably provided on the inner wall of the second sleeve 8 near the first sleeve 5. The other end of the second purification pipe 9 and the other end of the first purification pipe 6 are in contact with each other. A sealing sleeve 10 is fixed to the outer wall of the second purification pipe 9 near the first purification pipe 6, and the inner wall of the sealing sleeve 10 is in contact with the outer wall of the first purification pipe 6 near the second purification pipe 9. The sealing sleeve 10 is provided with a limiting mechanism, and the limiting mechanism is provided with a locking mechanism for locking the limiting mechanism on the filter box 1; One end of the second connecting pipe 11 is fixedly connected to the liquid outlet end of the first sleeve 5. The other end of the second connecting pipe 11 is connected to one end of the adsorption pipe 12. The other end of the adsorption pipe 12 is fixedly connected to the liquid inlet end of the water outlet pipe 3. One end of the first connecting pipe 7 is fixedly connected to the liquid outlet end of the water inlet pipe 2. The other end of the first connecting pipe 7 is fixedly connected to the liquid inlet end of the second sleeve 8.

[0018] In use, the inlet pipe 2 is connected to an external water body. The water flows through the first connecting pipe 7, the second sleeve 8, the second purification pipe 9, the sealing sleeve 10, the first purification pipe 6, the first sleeve 5, the second connecting pipe 11, and the adsorption pipe 12, and finally flows out from the outlet pipe 3. When maintenance of the first purification pipe 6 and the second purification pipe 9 is required, the locking mechanism is released from the limiting mechanism, and the integrated structure consisting of the sealing sleeve 10 and the second purification pipe 9 is moved towards the inner wall of the second sleeve 8. The sealing sleeve 10 will then move out from the side wall of the first purification pipe 6. Then, the first purification pipe 6 is manually rotated so that it is removed from the inner wall of the first sleeve 5 through the thread action. Then, the integrated structure consisting of the second purification pipe 9 and the sealing sleeve 10 is moved out from the inner wall of the second sleeve 8, thus realizing the quick replacement of the first purification pipe 6 and the second purification pipe 9.

[0019] Please see Figure 1 In this embodiment, a cover plate 4 is placed on the upper end of the filter box 1, and a limiting block is fixed to the lower end of the cover plate 4. The side wall of the limiting block is in contact with the inner wall of the filter box 1. By setting the cover plate 4 and the limiting block at the lower end, and the limiting block being in contact with the inner wall of the filter box 1, it is beneficial for the cover plate 4 to be placed quickly and stably on the upper end of the filter box 1.

[0020] Please see Figure 1 and Figure 3 In this embodiment, the limiting mechanism includes a support block 14 fixed to the side wall of the sealing sleeve 10, a through hole 15 extending through the support block 14, and a first hinge seat 16 fixed to the upper end of the support block 14. Guide rods are fixed to both sides of the inner wall of the filter box 1. The inner wall of the through hole 15 and the side wall of the guide rod are in contact with each other. The side wall of the support block 14 is in contact with one side wall of the filter box 1, which can provide support and guidance for the support block 14, and facilitate the stable movement of the support block 14 in the horizontal direction.

[0021] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the locking mechanism includes a first bolt 17 threaded onto the first hinge seat 16. One end of the first bolt 17 passes through the wall of the first hinge seat 16 and the filter box 1 and extends to the outside of the filter box 1. A first nut 18 is threaded onto the outer wall of the end of the first bolt 17 located outside the filter box 1. By setting the locking mechanism composed of the first bolt 17 and the first nut 18, the first hinge seat 16 can be quickly locked onto the filter box 1.

[0022] Please see Figure 1 and Figure 2 In this embodiment, a sound insulation plate 13 is fixed to the bottom surface of the inner wall of the filter box 1. The sound insulation plate 13 is located between the first sleeve 5 and the adsorption tube 12. By setting the sound insulation plate 13 and placing it between the first sleeve 5 and the adsorption tube 12, the noise generated by the water flow impact can be reduced.

[0023] Please see Figure 1 and Figure 7 In this embodiment, a filter element 19 is fixedly connected to the inner wall of the first purification pipe 6, and a wire mesh 25 is fixedly connected to the inner wall of the second purification pipe 9. By setting the filter element 19 in the first purification pipe 6 and the wire mesh 25 in the second purification pipe 9, the wire mesh 25 can be used to initially filter and remove larger particulate impurities. The filter element 19 can perform secondary filtration of the water quality, thus improving the filtration effect.

[0024] Please see Figure 1 and Figure 6 In this embodiment, the inner wall of the adsorption tube 12 is fixed with equidistantly distributed activated carbon rings 20. The activated carbon rings 20 are annular and have an inner diameter of less than ten centimeters. By setting the equidistantly distributed activated carbon rings 20 inside the adsorption tube 12, the filtered fluid can be adsorbed and purified, further improving the filtration effect.

[0025] Example 2: Please refer to Figure 6 Based on Embodiment 1, this application provides a technical solution: the inner wall of the filter box 1 is provided with two mutually symmetrical positioning mechanisms. The positioning mechanism includes a fixed block 21 fixed to the side wall of the guide rod, a second hinge seat 22 fixed to the upper end of the fixed block 21, a rotating block 23 rotatably mounted on the second hinge seat 22, and a second bolt 24 threadedly mounted on the rotating block 23. One end of the second bolt 24 passes through the wall of the filter box 1 and extends to the outside of the filter box 1. A second nut is threadedly installed on the outer wall of the end of the second bolt 24 located outside the filter box 1. In use, after releasing the support block 14 from the filter box 1, the support block 14 is moved to the position of the positioning mechanism. Then, the rotating block 23 is manually rotated to the inner wall of the first hinge seat 16. Then, the second bolt 24 passes through the rotating block 23, the first hinge seat 16 and the wall of the filter box 1 in sequence to fix the support block 14 on the positioning mechanism.

[0026] Working principle: First, the water inlet pipe 2 is connected to the external water body. The water flows into the second sleeve 8 through the first connecting pipe 7, then into the second purification pipe 9, passes through the sealing sleeve 10 and enters the first purification pipe 6. Then it flows through the first sleeve 5, the second connecting pipe 11 and the adsorption pipe 12 in sequence, and finally flows out from the water outlet pipe 3. During this process, the wire mesh 25 in the second purification pipe 9 performs preliminary filtration of the water to remove larger particulate impurities, the filter element 19 in the first purification pipe 6 performs secondary filtration, and the activated carbon ring 20 in the adsorption pipe 12 further adsorbs and purifies the filtered water. At the same time, the sound insulation plate 13 on the bottom of the inner wall of the filter box 1 reduces the noise generated by the water flow impact, and the cover plate 4 at the top of the filter box 1 is stably closed by the limiting block at the bottom to ensure stable operation of the device. When maintenance is required on the first purification tube 6 and the second purification tube 9, first unscrew the first nut 18 on the first bolt 17 in the locking mechanism and pull out the first bolt 17 to release the lock on the limiting mechanism. Push the integrated structure consisting of the sealing sleeve 10 and the second purification tube 9 to move away from the first purification tube 6 along the inner wall of the second sleeve 8, so that the sealing sleeve 10 is separated from the outer wall of the first purification tube 6. Next, manually rotate the first purification tube 6 so that it can be screwed out from the inner wall of the first sleeve 5 through the threaded engagement. Then, pull out the integrated structure consisting of the second purification tube 9 and the sealing sleeve 10 from the inner wall of the second sleeve 8 to complete the quick replacement of the first purification tube 6 and the second purification tube 9. If the support block 14 needs to be positioned, after unlocking it, move it to the positioning mechanism, rotate the rotating block 23 around the second hinge seat 22 until it fits against the first hinge seat 16, then use the second bolt 24 to pass through the rotating block 23 and the first hinge seat 16 and extend to the outside of the filter box 1, and tighten the second nut to fix it. The whole process can efficiently complete water filtration and component maintenance operations through the coordinated action of each component.
