[0022] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] refer to Figures 1 to 5 An apparatus for separating wastewater and organic phase in a nickel sulfate production system, comprising: a storage tank 1, a drainage pipe 2 fixedly installed at the bottom of one side of the storage tank 1, an emptying pipe 3 fixedly installed at the bottom of the other side of the storage tank 1, handles 4 on both sides of the storage tank 1, a water inlet pipe 5 fixedly installed at the top of the sealing cover 6, and a sealing cover 6 at the top of the storage tank 1;

[0024] An overflow pipe 8 is fixedly installed on the other side of the storage tank 1, and a cleaning component 10 is installed inside the storage tank 1.

[0025] Specifically, an overflow baffle 9 is provided inside the storage tank 1. The overflow baffle 9 is located in the upper part of the storage tank 1. The overflow baffle 9 is correspondingly provided at the connection between the overflow pipe 8 and the storage tank 1. A guide edge is provided on the top of the overflow baffle 9.

[0026] Specifically, an observation window 7 is provided on one side of the storage tank 1. The observation window 7 is located on the inner wall of the storage tank 1 and is at the same height as the storage tank 1.

[0027] Specifically, the cleaning component 10 includes a cleaning scraper ring 1001 that is attached to the inner wall of the storage tank 1, and a drive ring 1003 is provided inside the cleaning scraper ring 1001.

[0028] Specifically, an electric telescopic rod 1002 is connected to the top of the drive ring 1003, and the other end of the electric telescopic rod 1002 is fixedly connected to the top of the inner wall of the storage tank 1.

[0029] Specifically, a cleaning scraper 1004 is provided on the top of the drive ring 1003, a groove is provided on the outer side of the drive ring 1003, a protrusion is provided on the inner side of the cleaning scraper ring 1001, a drive gear 1005 is provided in the groove, and a tooth groove 1006 is provided on the inner side of the protrusion.

[0030] Specifically, the size of the drive gear 1005 is adapted to the tooth groove 1006, and the drive gear 1005 is connected to the cleaning scraper 1004 through the tooth groove 1006. There are two sets of cleaning scrapers 1004, and the cleaning scrapers 1004 are attached to the surface of the cleaning scraper ring 1001.

[0031] Example 1

[0032] In this embodiment, to ensure the cleanliness of the inner wall of the storage tank 1, a cleaning scraper ring 1001 is provided that adheres to the inner wall of the storage tank 1. The cleaning scraper ring 1001 has a drive ring 1003 inside. One end of the electric telescopic rod 1002 is fixedly connected to the drive ring 1003, and the other end is fixedly connected to the top of the inner wall of the storage tank 1. The electric telescopic rod 1002 drives the cleaning scraper ring 1001 to rise and fall. The rising and falling of the cleaning scraper ring 1001 scrapes away the stains remaining on the storage tank 1, thereby cleaning the inside of the storage tank 1.

[0033] As a further limitation of this technical solution, a cleaning scraper 1004 is provided on the top of the drive ring 1003, a groove is provided on the outer side of the drive ring 1003, a corresponding protrusion is provided on the inner side of the cleaning scraper ring 1001, a drive gear 1005 is provided in the groove, and a tooth groove 1006 is provided on the inner side of the protrusion. The size of the drive gear 1005 and the tooth groove 1006 are adapted to each other. A motor for driving is provided on the top of the drive gear 1005. By rotating the drive gear 1005, the tooth groove 1006 is driven to rotate the cleaning scraper 1004, thereby causing the cleaning scraper 1004 to move on the cleaning scraper ring 1001. Two sets of cleaning scrapers 1004 are provided. The cleaning scrapers 1004 are attached to the surface of the cleaning scraper ring 1001 and can clean the dirt scraped off the surface of the cleaning scraper ring 1001, ensuring the cleaning effect of the cleaning scraper ring 1001.

[0034] It should be noted that by setting the top of the overflow baffle 9 with a guide edge, some of the suspended organic phase in the wastewater will float to the surface of the wastewater. When the organic phase layer accumulates to a certain thickness, observed through the observation window 7, the flow rate of wastewater into the storage tank 1 is increased, causing the liquid level in the storage tank 1 to rise. At the same time, observed through the observation window 7, once the organic phase liquid level in the storage tank 1 exceeds the height of the overflow baffle 9, the wastewater inlet pipe 5 is closed, and the overflow pipe valve 8 is opened. The organic phase crosses the overflow baffle 9, passes through the guide edge, and begins to be discharged through the overflow pipe 8 under the action of gravity.

[0035] It is important to note that to prevent secondary cross-contamination between the organic phase and wastewater, during the organic phase discharge process, the observation window 7 must be checked regularly. The organic phase must not be completely emptied at once; a certain thickness of organic phase must remain in the storage tank 1. After the organic phase discharge is complete, open the drain valve 2 at the bottom of the storage tank 1 to discharge the wastewater to the next process. Again, the wastewater must not be completely emptied at once. After the solution in the storage tank 1 has been discharged once, reopen the wastewater inlet valve 5 to begin the circulation process. In case of emergency, the solution in the storage tank 1 can be discharged through the drain pipe 3.

[0036] Based on the above embodiments, in use, the wastewater is introduced into the storage tank 1 by opening the drain pipe 2. After settling, some suspended organic phase in the wastewater will float to the surface. When the organic phase layer accumulates to a certain thickness, observed through the observation window 7, the flow rate of wastewater into the storage tank 1 is increased, causing the liquid level in the storage tank 1 to rise. Simultaneously, the organic phase level in the storage tank 1 is observed through the observation window 7. Once the organic phase level exceeds the height of the overflow baffle 9, the wastewater inlet pipe 5 is closed, and the overflow pipe 8 valve is opened. The organic phase passes over the overflow baffle 9, flows through the guide edge, and begins to discharge through the overflow pipe 8 under gravity. After the organic phase is discharged, the valve at the bottom of the storage tank 1 is opened. The drain pipe 2 valve discharges wastewater to the next process. After long-term use, the cleaning scraper 1001 can be raised and lowered by the electric telescopic rod 1002. The raising and lowering of the cleaning scraper 1001 scrapes away the stains remaining on the inner wall of the storage tank 1, thereby cleaning the inner wall of the storage tank 1. The drive gear 1005 drives the tooth groove 1006 to rotate the cleaning scraper 1004, thereby moving the cleaning scraper 1004 on the cleaning scraper 1001 to scrape away the stains scraped off the surface of the cleaning scraper 1001. At the same time, the scraped stains can be discharged through the overflow pipe 8 to ensure the cleaning effect of the cleaning scraper 1001.
