Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical technology, and in particular to a high-efficiency filtration device for hydrometallurgical production. Background Technology

[0002] Industrial wastewater is inevitably generated during the hydrometallurgical processes of cobalt, nickel, and copper non-ferrous metals. This wastewater mainly includes leaching wastewater, extraction wastewater, synthesis precipitation wastewater, and other wastewater. After treatment, the metals contained in this wastewater precipitate primarily as hydroxides, forming wastewater sludge (some of this sludge also settles as sludge at the bottom of the wastewater pond). Because this wastewater sludge contains valuable metals such as cobalt, nickel, copper, and zinc, improper treatment can cause secondary pollution to the environment.

[0003] The utility model with publication number CN207062004U proposes a precision filtration device for cobalt-nickel-copper hydrometallurgical wastewater. In use, the wastewater first enters a sedimentation tank for sedimentation. The clearer solution after filtration flows into the right side of the sedimentation tank through the overflow hole. Then, the wastewater is pumped into the filter tank for filtration to remove impurities. The whole process is simple to operate and has a good treatment effect. The primary and secondary filter plates can be cleaned by passing high-pressure water through the spray pipe, making maintenance and cleaning convenient. However, even after cleaning the primary and secondary filter plates with high-pressure water, the impurities are still on the filter plates, and the impurities cannot be collected and treated, resulting in poor practicality of the device. Utility Model Content

The end faces of the lining plates are fixedly installed on the inner wall of the housing. One of the lining plates houses a motor, and the output shaft of the motor is fixedly installed at the end of a lead screw. The end of the lead screw away from the motor is rotatably installed on the surface of another lining plate, and both ends of the slide rod are fixedly installed on the surface of the lining plate.

[0012] Beneficial effects:

[0013] This utility model provides a high-efficiency filtration device for hydrometallurgical production. Waste liquid is continuously poured into the tank through the inlet, and then the waste liquid flows to the surface of the filter plate. The waste residue mixed in the waste liquid is filtered and intercepted on the surface of the filter plate. The filtered waste liquid flows into the second collection box for collection. Then, the rotation of the lead screw and the limiting of the slide rod cause the scraper to slide on the top of the filter plate, thereby scraping the waste residue accumulated on the surface of the filter plate into the first collection box for collection. This keeps the surface of the filter plate clean, prevents the filter holes from being blocked, ensures the normal use of the filter plate, and enables the device to effectively filter the waste liquid for a long time. This allows the device to operate for a long time and effectively collect and treat the waste residue, effectively enhancing the practicality of the device and making it convenient for users.

[0014] This utility model provides a high-efficiency filtration device for hydrometallurgical production. By sliding the second T-shaped block in the second T-shaped groove, the first collection box can be disassembled from the inside of the box, thereby making it easier to transfer and process the waste residue collected inside the first collection box. By sliding the first T-shaped block inside the first T-shaped groove, the second collection box can be disassembled from the inside of the box, thereby making it easier to process the filtered waste liquid collected inside the second collection box.

[0021] Please see Figures 1-5 This utility model provides a technical solution, including a box 1, with an inlet 11 fixedly installed through the top of the box 1, and a first collection box 13 and a second collection box 14 detachably installed inside the box 1. A filter plate 16 is provided above the second collection box 14, and a separation component is provided on the surface of the filter plate 16. The separation component includes a scraper 18, with a screw 22 threadedly connected to the surface of the scraper 18. The screw 22 is driven and installed inside the box 1, and a sliding rod 19 is slidably connected through the surface of the scraper 18. The sliding rod 19 is fixedly installed inside the box 1, and the bottom of the scraper 18 is attached to the surface of the filter plate 16.

[0022] Waste liquid is continuously poured into the tank 1 through the inlet 11. The waste liquid then flows to the surface of the filter plate 16, where it filters and traps the waste residue mixed in with the waste liquid. The filtered waste liquid flows into the second collection box 14 for collection. Then, the screw 22 rotates and the slide bar 19 limits the movement, causing the scraper 18 to slide on the top of the filter plate 16, thereby scraping the waste residue accumulated on the surface of the filter plate 16 into the first collection box 13 for collection. This keeps the surface of the filter plate 16 clean and prevents the filter holes from being blocked, ensuring the normal use of the filter plate 16. This allows the device to effectively filter the waste liquid for a long time, enabling the device to operate for extended periods and effectively collect and treat waste residue, thus enhancing the practicality of the device and making it convenient for users.

[0023] A mounting bracket 2 is fixedly installed inside the housing 1. Liners 21 are symmetrically fixedly installed at both ends of the mounting bracket 2. The end faces of the liners 21 are fixedly installed on the inner wall of the housing 1. A motor is built into one of the liners 21. The output shaft of the motor is fixedly installed at the end of the lead screw 22. The end of the lead screw 22 away from the motor is rotatably installed on the surface of the other liner 21. Both ends of the slide rod 19 are fixedly installed on the surface of the liner 21.

[0024] By rotating the liner 21 in both directions, the screw 22 rotates, causing the scraper 18 to slide back and forth on the surface of the filter plate 16, thereby enabling the scraper 18 to effectively clean the surface of the filter plate 16.

[0025] Mounting bracket 2 has mounting base 15 fixedly mounted on its surface. Filter plate 16 is fixedly mounted through the mounting base 15. Baffle 17 is fixedly mounted on the top of mounting base 15. Scraper 18 slides through the surface of baffle 17.

[0026] This ensures that the filter plate 16 is stably installed, making it more stable during the waste liquid filtration process. At the same time, the baffle 17 installed around the filter plate 16 prevents the waste liquid poured in through the inlet 11 from splashing around, thus improving the filtration efficiency.

[0027] The liner 21 and the mounting base 15 are both recessed with second T-shaped grooves 25. The surface of the first collection box 13 is symmetrically fixed with second T-shaped blocks 26. The two second T-shaped blocks 26 are slidably sleeved on the inner wall of the second T-shaped grooves 25. The bottom of the mounting base 15 is fixedly installed with first T-shaped blocks 23. The top of the second collection box 14 is recessed with first T-shaped grooves 24. The first T-shaped blocks 23 are slidably sleeved on the inner wall of the first T-shaped grooves 24.

[0028] The first collection box 13 can be disassembled from the inside of the box body 1 by sliding the second T-shaped block 26 in the second T-shaped groove 25, so that the waste residue collected in the first collection box 13 can be transferred and processed more conveniently. The second collection box 14 can be disassembled from the inside of the box body 1 by sliding the first T-shaped block 23 in the first T-shaped groove 24, so that the filtered waste liquid collected in the second collection box 14 can be processed more conveniently.

[0029] The top of the first collection box 13 is provided with a sloping groove 27, and the top of the sloping groove 27 is on the same horizontal line as the top of the mounting base 15.

[0030] This allows the scraper 18 to push the waste residue on the surface of the filter plate 16 to the edge of the mounting base 15, and then slide more smoothly into the first collection box 13 through the inclined groove 27, further improving the collection efficiency.

[0031] A liquid collecting cylinder 12 is fixedly installed on the inner wall of the housing 1. The liquid collecting cylinder 12 has a funnel-shaped structure, and the filter plate 16 is located below the liquid collecting cylinder 12.

[0032] When the waste liquid enters the inlet 11, it slides down into the collection cylinder 12. The waste liquid is gathered at the bottom of the collection cylinder 12 and falls onto the surface of the filter plate 16, thus preventing the waste liquid from splashing.
