Description

Technical Field

[0001] This utility model relates to the field of nickel oxide preparation technology, specifically to a multi-stage filtration device for nickel oxide production. Background Technology

[0002] Nickel oxide is an important transition metal oxide with a cubic crystal structure. It is typically a green or black powder, insoluble in water but soluble in acids. It possesses excellent chemical stability, electrochemical activity, and magnetic properties, and has wide applications in various fields. Industrial production usually involves the thermal decomposition of nickel salts or electrodeposition. To improve the purity of nickel oxide solutions, a filtration device is required for purification. Traditional multi-stage filtration devices employ a single vacuum filtration method, resulting in relatively low pressure in the upper filtration stage and thus poor overall filtration efficiency.

The upper end of the discharge funnel is fixedly connected to the lower end of the limiting edge.

[0006] Preferably, the upper end of the feed section is sealed with a top plate via a flange, and the upper end of the liquid distributor is provided with a feed pipe, which passes through the top plate and is connected to the liquid distributor.

[0007] Preferably, a sealing ring is provided between the flanges of the feeding section, the filtering section, the receiving section and the discharging section.

[0017] Please see Figure 1-5This utility model provides a multi-stage filtration device for nickel oxide production, including a feeding section 1, a filtration section 2, a receiving section 3, and a discharging section 4. The feeding section 1, the filtration section 2, the receiving section 3, and the discharging section 4 are connected sequentially by flanges. The combination of the filtration section 2 and the receiving section 3 is set in corresponding quantities according to filtration requirements. A liquid distributor 5 is provided at the upper end of the inside of the feeding section 1. A filter plate 6 is provided inside the filtration section 2. A discharge funnel 7 is provided inside the filtration section 2 and at the lower end of the filter plate 6. The lower end of the discharge funnel 7 extends into the inside of the receiving section 3. A discharge hood 8 is connected to the lower end of the discharging section 4. A vacuum tube 9 is provided through the side wall of the filtration section 2.

[0018] In use, the combination of filtration section 2 and receiving section 3 is set according to the corresponding number of filtration requirements to form the overall structure of a multi-stage filtration device. The nickel oxide solution to be filtered is distributed into the interior of the feeding section 1 through the liquid distributor 5 and evenly distributed on the filter plate 6 inside the filtration section 2. A vacuum is drawn inside the filtration section 2 through an external vacuum device and a vacuum tube 9, and different pressures are generated inside the different levels of the filtration section 2 to ensure the filtration effect. The nickel oxide solution that has been filtered in the upper layer is collected through the discharge funnel 7 and then fed into the interior of the receiving section 3. The combination of filtration section 2 and receiving section 3 stores the nickel oxide solution inside the upper receiving section 3 inside the filtration section 2 and receiving section 3. The above filtration process is repeated through the lower filtration section 2. Finally, the filtered nickel oxide solution is discharged to the outside through the discharge hood 8 at the lower end of the discharge section 4.

[0019] The filter section 2 has a limiting edge 10 inside, the filter plate 6 abuts against the limiting edge 10, and a fixing ring 11 is fixedly connected to the limiting edge 10 and the upper end of the filter plate 6 by bolts. The upper end of the discharge funnel 7 is fixedly connected to the lower end of the limiting edge 10. The limiting edge 10 provides support for the installation of the filter plate 6, and the fixing ring 11 is fixed by bolts to improve the connection strength between the filter plate 6 and the limiting edge 10. The limiting edge 10 also provides support for the discharge funnel 7.

[0020] The upper end of the feed section 1 is sealed with a top plate 12 via a flange. The upper end of the liquid distributor 5 is provided with a feed pipe 13. The feed pipe 13 passes through the top plate 12 and is connected to the liquid distributor 5. By setting the top plate 12 as the upper end of the feed section 1 for sealing, the nickel oxide solution to be filtered is input into the interior of the liquid distributor 5 through the feed pipe 13 and distributed into the interior of the feed section 1.

[0021] A sealing ring 14 is provided between the flanges of the feeding section 1, the filtering section 2, the receiving section 3 and the discharging section 4 to improve the sealing performance of the overall filtration device and ensure the vacuum effect inside the filtration device.
