A filtration and separation device for lithium perchlorate solution

Abstract

This utility model discloses a filtration and separation device for lithium perchlorate solution, including a first fixed plate, a filtration mechanism, and a vibration mechanism. The vibration mechanism includes four springs fixedly mounted on the upper surface of the first fixed plate. A material tank is fixedly mounted on the upper surface of the four springs. Two second fixed plates are fixedly mounted on the lower surface of the material tank, positioned on the upper surface of the first fixed plate. An eccentric wheel is rotatably mounted between the two second fixed plates. The filtration mechanism includes three filter plates extending through one side of the material tank, each with several filter holes on its surface. This structure enables highly efficient filtration and separation of lithium perchlorate solution. The four springs extend and retract with the vibration of the material tank, and the eccentric wheel rotates between the two second fixed plates, generating a continuous vibration effect. This causes the solution in the material tank to constantly agitate, preventing clogging of the filter holes and ensuring that the solution can smoothly pass through the filter holes on the filter plates for filtration and separation.

Description

Technical Field

[0001] This utility model relates to the field of lithium perchlorate purification technology, and in particular to a filtration and separation device for lithium perchlorate solution. Background Technology

[0002] Lithium perchlorate, as an important chemical raw material, is widely used in battery electrolytes, aerospace propellants, and other fields. Its purity directly affects product performance. During the preparation of lithium perchlorate, the solution often contains solid particles such as reaction byproducts and raw material impurities, which need to be purified by filtration.

[0003] Traditional filtration equipment often uses a single filter layer structure, which has limited filtration precision and is difficult to effectively remove impurities of different particle sizes. Furthermore, the filter pores are easily clogged during filtration, leading to decreased filtration efficiency, frequent shutdowns for cleaning, and disruptions to production continuity. Additionally, some equipment lacks a stable vibration-assisted structure, resulting in slow solution filtration rates, inconvenient filter plate installation and disassembly, and high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a filtration and separation device for lithium perchlorate solution, which can achieve precise filtration in stages, improve the removal of impurities, reduce filter pore clogging through vibration assistance, improve filtration efficiency, and facilitate filter plate maintenance and replacement.

[0005] To achieve the above objectives, a filtration and separation device for lithium perchlorate solution is provided, comprising a first fixed plate, a filtration mechanism, and a vibration mechanism. The vibration mechanism includes four springs fixedly disposed on the upper surface of the first fixed plate, a material bucket fixedly disposed on the upper surface of the four springs, and two second fixed plates fixedly disposed on the lower surface of the material bucket, disposed on the upper surface of the first fixed plate. An eccentric wheel is rotatably disposed between the two second fixed plates. The filtration mechanism includes three filter plates that penetrate one side of the material bucket, and each of the three filter plates has a plurality of filter holes on its surface.

[0006] According to the filtration and separation device for lithium perchlorate solution, a motor is fixedly installed on the upper surface of the first fixed plate, and a rotating shaft is fixedly connected to the output end of the motor. The rotating shaft rotates through one of the second fixed plates and is rotatably connected to the inner wall of the other second fixed plate. An eccentric wheel is fixedly installed on the surface of the rotating shaft.

[0007] According to the filtration and separation device for lithium perchlorate solution, an inclined block is fixedly provided on the lower surface of the material tank, and the eccentric part of the eccentric wheel abuts against the force-bearing surface of the inclined block.

[0008] According to the filtration and separation device for lithium perchlorate solution, three fixed blocks are fixedly distributed on the surface of the material tank, and three sliding columns are fixedly disposed on the upper surface of the first fixed plate. The three sliding columns slide through the fixed blocks respectively, and limit blocks are fixedly disposed at the other end of each of the three sliding columns.

[0009] According to the aforementioned filtration and separation device for lithium perchlorate solution, the filter plates are adapted to the material tank, sealing rings are fixedly provided on the upper and lower surfaces of the three filter plates, handles are fixedly provided on one side of the three filter plates, and the three filter plates are slidably connected to the inner wall of the material tank.

[0010] According to the filtration and separation device for lithium perchlorate solution, a guide plate is fixedly installed at the bottom of the inner wall of the material tank, and an output pipe is opened at the guide point of the material tank near the guide plate.

[0011] According to the filtration and separation device for lithium perchlorate solution, an input pipe is fixedly installed on the upper surface of the material tank, and valves are installed on the surfaces of the input pipe and the output pipe.

[0012] According to the filtration and separation device for lithium perchlorate solution, the surface of the first fixed plate is provided with four positioning holes.

[0013] This utility model has the following beneficial effects: 1. Compared with the existing technology, this lithium perchlorate solution filtration and separation device has a three-stage filter plate graded filtration structure, with the filter pore size decreasing from top to bottom. It can intercept large, medium and small particle size impurities in sequence, with higher filtration accuracy and can effectively improve the purity of lithium perchlorate solution.

[0014] 2. Compared with the existing technology, this lithium perchlorate solution filtration and separation equipment uses a motor-driven eccentric wheel in conjunction with springs and sliding columns to achieve stable vibration of the material tank, accelerate solution penetration, and reduce filter pore clogging. At the same time, the filter plate adopts a pull-out design, with handles and sealing rings, making installation and disassembly convenient and maintenance more efficient.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4 This utility model provides a filtration and separation device for lithium perchlorate solution, which includes a first fixed plate 4, a filtration mechanism 2, and a vibration mechanism 3. The vibration mechanism 3 includes four springs 11 fixedly mounted on the upper surface of the first fixed plate 4. A material tank 1 is fixedly mounted on the upper surface of the four springs 11. Two second fixed plates 13 are fixedly mounted on the lower surface of the material tank 1 and mounted on the upper surface of the first fixed plate 4. An eccentric wheel 15 is rotatably mounted between the two second fixed plates 13. The filtration mechanism 2 includes three filter plates 21 that penetrate one side of the material tank 1. Each of the three filter plates 21 has a plurality of filter holes 20 on its surface.

[0019] The filter holes 20 are distributed in a progressively smaller size distribution from top to bottom. The filter holes 20 of the upper filter plate 21 have the largest diameter and are used to intercept impurities with larger particle sizes in the solution. The filter holes 20 of the middle filter plate 21 have the next smaller diameter and are used to intercept impurities with medium particle sizes. The filter holes 20 of the lower filter plate 21 have the smallest diameter and are used to intercept impurities with fine particle sizes, thus achieving graded progressive filtration.

[0020] A motor 16 is fixedly mounted on the upper surface of the first fixed plate 4. A rotating shaft 14 is fixedly connected to the output end of the motor 16. The rotating shaft 14 rotates through one of the second fixed plates 13 and is rotatably connected to the inner wall of the other second fixed plate 13. An eccentric wheel 15 is fixedly mounted on the surface of the rotating shaft 14.

[0021] The motor 16 drives the rotating shaft 14 and the eccentric wheel 15 to rotate. The eccentric wheel 15 abuts against the inclined block 17, causing the material bucket 1 to vibrate under the guidance of the spring 11 and the sliding column 10, which accelerates the solution through the filter plate 21 and reduces clogging.

[0022] An inclined block 17 is fixedly installed on the lower surface of the material bucket 1, and the eccentric part of the eccentric wheel 15 abuts against the force-bearing surface of the inclined block 17. Damping is provided at the connection between the three filter plates 21 and the material bucket 1.

[0023] Three fixed blocks 9 are fixedly distributed on the surface of the material bucket 1, and three sliding pillars 10 are fixedly disposed on the upper surface of the first fixed plate 4. The three sliding pillars 10 slide through the fixed blocks 9 respectively, and limit blocks 18 are fixedly disposed at the other end of each of the three sliding pillars 10.

[0024] The filter plates 21 are adapted to the material bucket 1. Sealing rings 19 are fixedly installed on the upper and lower surfaces of the three filter plates 21. Handles 22 are fixedly installed on one side of the three filter plates 21. The three filter plates 21 are slidably connected to the inner wall of the material bucket 1.

[0025] A guide plate 7 is fixedly installed at the bottom of the inner wall of the material barrel 1, and an output pipe 8 is opened at the guide point of the material barrel 1 near the guide plate 7.

[0026] An input pipe 5 is fixedly installed on the upper surface of the material barrel 1. Valves 6 are installed on the surfaces of the input pipe 5 and the output pipe 8. Four positioning holes 12 are opened on the surface of the first fixed plate 4.

[0027] Working Principle: The equipment is fixed at the designated position through the positioning hole 12. Valve 6 of the input pipe 5 is opened, and lithium perchlorate solution is injected into the material tank 1 through the input pipe 5. The motor 16 is started, driving the rotating shaft 14 to rotate the eccentric wheel 15. The eccentric part of the eccentric wheel 15 continuously presses against the inclined block 17, and with the elastic restoring action of the four springs 11, the material tank 1 vibrates up and down along the sliding column 10. Under the action of vibration, the solution passes through three layers of filter plates 21 in sequence. The upper filter plate 21 intercepts large-diameter impurities, the middle layer intercepts medium-diameter impurities, and the lower layer intercepts fine impurities, achieving graded filtration. The filtered pure solution is guided to the output pipe 8 through the guide plate 7, and valve 6 of the output pipe 8 is opened for collection. When the filter plate 21 needs cleaning or replacement, valve 6 is closed to stop feeding. The filter plate 21 is pulled out of the material tank 1 through the handle 22, cleaned, and then reinserted. The sealing ring 19 ensures the sealing performance of the connection, preventing solution leakage.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
