[0010] Considering the problems of existing multi-stage manganese sulfate solution impurity removal devices, such as the easy accumulation and clogging of filter screens by impurities, and the complex disassembly and maintenance procedures, By using a fixed box, insert rod, support spring, and filter cylinder, the manganese sulfate solution to be treated is fed into the front filter cylinder during use, and the reaction reagent is added through the inlet tube. The drive motor is then activated, causing the shaft and support frame to rotate. This causes the support frame to move the cleaning brush on the support sleeve to scrape the inside of the filter cylinder, accelerating the reaction while reducing clogging of the filter cylinder and preventing impurities from accumulating and blocking the mesh, thus significantly improving filtration efficiency. When the filter cylinder needs to be replaced, the top cover is opened, and the pull rod is pulled, causing the insert rod to slide within the fixed box. The support spring contracts under pressure, and the insert rod is simultaneously pulled out from the insertion holes on both sides of the groove on the fixed sleeve. This facilitates easy disassembly and replacement of the filter cylinder, reducing disassembly and maintenance time and achieving both efficient impurity removal and convenient maintenance.

[0025] This utility model provides, for example Figure 1-5 The multi-stage manganese sulfate solution impurity removal device shown includes a front filter cartridge 1, a fixed sleeve 2 is provided inside the front filter cartridge 1, two sets of fixed boxes 3 are snapped on the top of the fixed sleeve 2, and the two sides of the fixed box 3 are slidably connected to the insert rod 4. One end of the insert rod 4 is fixedly connected to the support spring 5, and the surface of the insert rod 4 is fixedly connected to the pull rod 6. A filter screen cylinder 7 is fixedly connected to one side of the fixed box 3. The bottom of the front filter cartridge 1 is connected through a connecting pipe 16 with a solenoid valve 18. The connecting pipe 16 is connected in series with at least two nanofiltration filter cartridges 17. The nanofiltration filter cartridge 17 is filled with a charged nanofiltration membrane with a pore size of 1-2 nm and a molecular weight cutoff of 200-1000 Da, which can achieve selective separation of manganese ions and high-valence impurities. The three-stage series structure is connected by an electric regulating valve and a pressure sensor to form a closed-loop control system. The controller (24) adjusts the valve opening according to the real-time pressure data.

[0026] The front filter cartridge 1 is provided with a top cover 8. A support shell 9 is fixedly connected to the top surface of the top cover 8. A drive motor 10 is fixedly connected inside the support shell 9. A rotating shaft 11 is fixedly connected to the output end of the drive motor 10. A support frame 12 is sleeved on the surface of the rotating shaft 11. Support sleeves 13 are sleeved on both sides of the support frame 12. A cleaning brush 14 is fixedly connected to one side of the support sleeve 13. The cleaning brush 14 contacts the inner wall of the filter cartridge 7. Several sets of support rods 15 are fixedly connected to the surface of the rotating shaft 11.

[0027] The top cover 8 provides rigid support for the support shell 9, which in turn provides a stable installation space for the drive motor 10. The drive motor 10 drives the rotating shaft 11 to rotate, which in turn drives the support frame 12 to rotate, thereby driving the cleaning brush 14 to scrape the inner wall of the filter screen cylinder 7 to prevent impurities from clogging the mesh and to accelerate the mixing of the reaction reagents. The cleaning brush 14 is made of acid-resistant polytetrafluoroethylene, and the support rod 15 enhances the structural strength of the rotating shaft 11 to prevent deformation during high-speed rotation.

[0028] The top of the top cover 8 is connected to a drug inlet pipe 19, which is used to inject the impurity removal reagent. The top of the top cover 8 is also connected to a feed pipe 20, which is used to input manganese sulfate solution.

[0029] The inlet tube 19 facilitates the injection of reaction reagents such as manganese fluoride, which react with calcium and magnesium ions in the manganese sulfate solution to form a precipitate. The feed tube 20 facilitates the input of the manganese sulfate solution to be treated, and its sealing design, combined with the top cover 8, prevents leakage.

[0030] Two sets of limit bolts 21 are fixedly connected to the surface of the front filter cartridge 1, and several sets of through holes are opened on the surface of the fixed sleeve 2.

[0031] The limiting bolt 21 is used to fix the relative position of the front filter cartridge 1 and the top cover 8 to prevent displacement, and the through hole facilitates the passage of manganese sulfate solution.

[0032] Among them, a number of positioning rods 22 are fixedly connected to the surface of the front filter cartridge 1, and a fixing frame 23 is fixedly connected to one end of the positioning rod 22. A controller 24 is provided on one side of the fixing frame 23.

[0033] The positioning rod 22 facilitates the support of the front-end filter cartridge 1, and the fixing frame 23 provides an installation platform for the front-end filter cartridge 1, nanofiltration filter cartridge 17 and controller 24. It integrates electrical control circuits, and the controller 24 coordinates the drive motor 10, solenoid valve 18 and other actuators. By setting the start and stop sequence of the reverse osmosis unit, it realizes the automated impurity removal process.

[0034] Working principle: When using this multi-stage manganese sulfate solution impurity removal device, the manganese sulfate solution to be treated is input into the front filter cartridge 1, and the reaction reagent is added through the inlet pipe 19. Then, the drive motor 10 is started, which drives the rotating shaft 11 and the support frame 12 to rotate. The support frame 12 drives the cleaning brush 14 on the support sleeve 13 to scrape the inside of the filter screen 7. While stirring and accelerating the reaction, it reduces the clogging of the filter screen 7, prevents impurities from accumulating and clogging the mesh, and significantly improves the filtration efficiency. When the filter screen 7 needs to be replaced, the top cover 8 is opened, and then the pull rod 6 is pulled. The pull rod 6 pulls the insertion rod 4 to slide in the fixed box 3. The support spring 5 is compressed under force, and at the same time, the insertion rod 4 is pulled out from the insertion holes on both sides of the groove on the fixed sleeve 2. This makes it easy to disassemble and replace the filter screen 7, reduces the time for disassembly and maintenance, and achieves the functions of efficient impurity removal and convenient maintenance.

[0035] Experimental protocol Control group setup Traditional device: uses a bolt-fixed filter screen cylinder, without an automatic cleaning brush.

[0036] This patented device features a quick-release structure (fixed box + insert rod) and a motor-driven cleaning brush 14.

[0037] Test conditions Solution: Manganese sulfate solution containing fixed impurities (diatomaceous earth simulated suspended particles, Ca²⁺ / Mg²⁺ ion concentration 200 ppm). Flow rate: constant 5 m³ / h Running time: 8 consecutive hours Comparison of experimental results The traditional equipment of the project improves the efficiency of this patented equipment. Initial flux: 320 L / h·m² 315 L / h·m² -1.6% After 4 hours, the flux was 185 L / h·m² - 280 L / h·m², an increase of 51.4%. Flux decay rate: 42.2% / h 11.1% / h ↓73.7% 8h pressure difference 35 kPa 18 kPa ↓48.6% The time taken to replace the mesh cylinder was 22 min - 4 min, a decrease of 81.8%. Anti-clogging performance The cleaning brush 14 continuously scrapes, reducing the flux attenuation rate to 1 / 4 of that of conventional devices, proving its effectiveness in alleviating mesh clogging.

[0038] After 8 hours of operation, the pressure difference only increased by 12 kPa (compared to 28 kPa for conventional equipment), reducing the equipment load.

[0039] The comparative experiments described above demonstrate that after 8 hours of continuous operation, this device maintains a filtration flux retention rate of up to 89% (compared to 58% for traditional devices), and reduces single maintenance time by 81.8%. The overall filtration efficiency is improved by approximately 6.5 times, significantly outperforming existing technologies.
