[0029] Example 2

[0030] The discharging unit includes a first discharging pipe 200, a second discharging pipe 210, a third discharging pipe 220 and a fourth discharging pipe 230. The top of the flat cover 17 is provided with a first discharging port 20, a second discharging port 21, a third discharging port 22 and a fourth discharging port 23.

Each discharge pipe is connected to a pressure transmitter, which cooperates with the cylinder pressure transmitter on the forward blowing pipe 100. By detecting the pressure difference change, it can accurately locate which filter zone's filter element 8 is blocked, close the discharge valve of the discharge pipe on the corresponding zone, and the back-flushing mechanism back-flushes the filter element 8 of the filter zone.

[0031] The feed unit includes a feed port 12, which is opened on the side wall of the lower cylinder 19. The feed port 12 is connected to a feed pipe 120, and the body of the feed pipe 120 is connected to a feed valve 25. The pressurized material enters the filter through the feed pipe 120 and the feed port 12 and is filtered by the filter element 8.

[0032] Example 3

[0033] The back-flushing mechanism includes a back-flushing valve 32, and the opposite ends of the back-flushing valve 32 are respectively connected to a back-flushing port 33 and a back-washing port 34, and the other end of the back-flushing valve 32 is connected to a back-flushing main pipe 31. The end of the back-flushing main pipe 31 away from the back-flushing valve 32 is connected to the end of the discharge main pipe 30, and the pipe body of the back-flushing main pipe 31 is connected to the regeneration pipe 150. The material is filtered through the filter element 8. Long-term filtration causes the filter element 8 to be blocked. The pressure difference changes detected by the first pressure transmitter 42, the second pressure transmitter 43, the third pressure transmitter 44, the fourth pressure transmitter 45 and the cylinder pressure transmitter 41 can accurately locate the filter partition where the filter element 8 is blocked. If the filter element 8 of the filter partition corresponding to the first discharge port 20 is blocked, the first discharge valve 26 and the right pipeline are closed together, and the backwash valve 32 is switched to the backwash port 33. The backwash port 33 is connected to the backwash main pipe 31. The backwash gas passes through the backwash port 33, the backwash valve 32, the backwash main pipe 31, the first discharge valve 26 and the first discharge port 20 to backwash the filter element 8 of the filter partition, and then the backwash valve 32 is switched to the backwash port 34 to backwash the filter element 8 to restore the filtering performance of the filter element 8.

[0034] Example 4

[0035] The side wall of the lower cylinder 19 is also provided with a forward blowing port 10, a vent port 11 and a blowing port 13. The forward blowing port 10 and the vent port 11 are arranged above the feed port 12, and the blowing port 13 is arranged close to the tee pipe 14. The forward blowing port 10 is connected to the forward blowing pipe 100, and the body of the forward blowing pipe 100 is connected to the forward blowing valve 35 and the cylinder pressure transmitter 41. The end of the forward blowing pipe 100 away from the forward blowing port 10 is connected to the body of the backwashing main pipe 31, the vent port 11 is connected to the vent pipe 110, and the body of the vent pipe 110 is connected to the vent valve 24, the blowing port 13 is connected to the blowing pipe 130, and the body of the blowing pipe 130 is connected to the blowing valve 36.

[0036] A liquid level gauge port 9 is provided on the side wall of the lower cylinder 19 , and a liquid level gauge 40 is connected to the liquid level gauge port 9 .

[0037] When the device has been running for too long, ordinary backflushing and backwashing can no longer restore the filtering capacity of the filter element 8, and circulating cleaning is required at this time. At this time, close the feed valve 25, open the regeneration pump 39, and extract the regeneration liquid in the regeneration tank 37. After passing through the regeneration pipe 150 and the backwashing main pipe 31, the regeneration liquid enters the filter through the first discharge valve 26, the second discharge valve 27, the third discharge valve 28 and the fourth discharge valve 29 respectively, and circulates and cleans the filter element 8. Then, open the drain valve 16. When the liquid level in the filter is below the vent port 11, close the drain valve 16, then open the blowing valve 36 and the vent valve 24 to aerate the regeneration liquid and enhance the circulating flushing effect of the regeneration liquid. After the filter element 8 is rinsed clean, close the regeneration valve 15, the blowing valve 36 and the vent valve 24, then open the drain valve 16 to discharge the regeneration liquid, and then backwash and backwash the filter element 8. While backwashing, open the forward blowing valve 35, and perform forward blowing and backwashing at the same time. After the filter element 8 is dried, the operation can be continued.

[0038] The working principle of the microporous filtration device for positive electrode materials of the utility model is as follows:

[0039] Material enters the filter through feed pipe 120, is filtered by filter element 8, and then discharged through the discharge port, flowing through the discharge main pipe 30 to enter the next process. The material is filtered by filter element 8 for a long time, causing the filter element 8 to become clogged. The pressure differential changes detected by the first pressure transmitter 42, the second pressure transmitter 43, the third pressure transmitter 44, the fourth pressure transmitter 45, and the cylinder pressure transmitter 41 can accurately locate the filter zone of the clogged filter element 8. Based on the filter zone corresponding to the clogged filter element 8, the corresponding discharge valve and the right pipeline are closed, and the backwash valve 32 is switched to the backwash port 33. The backwash port 33 is connected to the backwash main pipe 31. The backwash gas passes through the backwash port 33, the backwash valve 32, the backwash main pipe 31, and the corresponding discharge valve and discharge port to backwash the filter element 8 in the filter zone. The backwash valve 32 is then switched to the backwash port 34 to backwash the filter element 8, restoring the filtration performance of the filter element 8.

[0040] The utility model relates to a positive electrode material microporous filtering device. The filtered regeneration liquid is backwashed. Under the condition of ensuring the unchanged cleaning effect, the effective components in the drainage liquid can be fully utilized, and the consumption of the cleaning liquid is reduced.
