[0002] With the wide application of lithium batteries in new energy vehicles, energy storage and 3C electronic products, high-performance ternary positive electrode materials play an important role in power batteries, and the research and development of ternary precursors has never stopped. At present, the ternary precursors are usually produced by the precipitation method in the industry, and therefore there is a troublesome wastewater treatment problem. The common ternary precursor wastewater treatment method on the market is grading purification treatment, which is completed by physical methods such as flocculation and filtration.

[0003] For example, the Chinese patent with the publication number CN114470901B discloses a bottle embryo mold screw port efficient cooling waterway, a horizontal plate is anchored in the middle position of the inside of the tank body through bolts, the horizontal plate divides the inside space of the tank body into two parts, and a filter screen is anchored on the top of the horizontal plate through bolts; the filter screen and the stirring blade two are matched, the top of the filter screen is a conical body, the inclined surface is arranged to avoid flocculation deposition on the top of the filter screen, grooves are arranged on the surface of the filter screen to increase the surface area of the filter screen after expansion, increase the effective filtering area of the filter screen, and block the flocculation into the filter screen through the grooves, meanwhile, the grooves are provided with inclined side walls to facilitate flocculation deposition, and the stirring blade two is arranged on the filter screen, the outer protruding curved surface of the stirring blade two guides the water flow to flow to the filter screen, so that the filter screen is washed, the flocculation is guided through the above-mentioned method, the filtering area of the filter screen is expanded, and the filter screen is prevented from being blocked by the method of stirring the water flow to wash the filter screen by the stirring blade two.

[0004] In the above technical solution, the problem of preventing the filter screen from being blocked is solved by the cooperation of the stirring blade two and the filter screen. However, the simple groove design is not enough to form a good anti-blocking effect, on the contrary, the flocculation is easy to be blocked in the groove and difficult to clean, which affects the filtering effect, and when the stirring blade two is used to stir the water flow to wash the filter screen, the water flow is washed from one side of the filter screen. This washing method can further push the flocculation to the filter screen by the hitting force of the water flow, so that the flocculation in the gap of the filter screen is more firmly adhered to the filter screen, resulting in poor cleaning effect.

[0034] As Figures 2 to 5 and Figures 7 to 10As shown, the filter separation mechanism includes a float 19 mounted at the bottom of the insertion rod 11, the bottom of the float 19 is provided with a connecting piece 20, the bottom of the connecting piece 20 is annularly and equidistantly provided with a connecting skeleton 21, the connecting skeleton 21 is provided with a filter piece 22, the bottom of the connecting skeleton 21 is fixedly connected with a rotating block 24, the bottom of the tank body 1 is provided with a partition plate 23, the top of the partition plate 23 is provided with a rotating groove matched with the shape of the rotating block 24, the outer wall of the tank body 1 is provided with a mounting rack 6, the mounting rack 6 is provided with a first motor 7, the output end of the first motor 7 is provided with a mounting block 8, the output end of the first motor 7 is sealingly connected with the tank body 1, the rotation of the first motor 7 and the mounting block 8 will not affect the sealing of the device, the mounting block 8 is provided with a connecting rope 18, the use of the connecting rope 18 will not affect the sealing of the device, the sealing treatment of the device is a mature technology, the end of the connecting rope 18 away from the mounting block 8 is fixed on the inner wall of the tank body 1, the bottom of the insertion rod 11 is provided with an insertion groove 17 matched with the shape of the connecting rope 18; the bottom of one side of the connecting skeleton 21 is fixedly connected with a first supporting skeleton 25, the top of the first supporting skeleton 25 is provided with a second supporting skeleton 26, the first supporting skeleton 25 and the second supporting skeleton 26 are provided with a rotating shaft 27, the top of the first supporting skeleton 25 is provided with a partition piece 28, the top of the second supporting skeleton 26 is fixedly connected with a connecting rod 29, the mounting rack 6 and the first motor 7 are mature technologies, therefore, the working principle will not be described in detail, the mounting rack 6 is fixedly installed on the outer wall of the tank body 1 through screws, the tank body 1 is provided with a mounting hole, one end of the connecting rope 18 is wound and fixed on the mounting block 8, the length of the connecting rope 18 wound on the mounting block 8 can be changed by starting the first motor 7 to drive the mounting block 8 to rotate, so as to change the length of the connecting rope 18 in the tank body 1, the partition plate 23 is provided with a groove matched with the shape of the float 19, such as Figure 2As shown, in the initial state, the float 19 is in close contact with the partition plate 23, forming a seal therebetween, at this time, the connecting rope 18 is wound on the mounting block 8 to the maximum extent near one end of the mounting block 8, the connecting rope 18 is in a tensioned state, the plug rod 11 extrudes the float 19 to make it close to the partition plate 23, and the float 19 is subjected to the pulling force of the plug rod 11, at this time, the spring 15 in the sliding groove 14 is stretched to produce elastic deformation, the connecting skeleton 21 at the bottom of the connecting sheet 20 and the filter sheet 22 are elastically deformed and bent in the direction of the connecting sheet 20 to produce avoidance, the water inlet pipe 2 and the medicine inlet pipe 3 are opened to allow waste liquid and liquid medicine to flow in, the water outlet pipe 4 and the flocculation outlet 5 are closed, then the liquid in the tank body 1 is mixed uniformly by the stirring rod 12 and the stirring sheet 13, and after the flocculation is generated, the first motor 7 is started to reverse, so that the connecting rope 18 wound on the mounting block 8 is loosened, at this time, the spring 15 and the deformation are restored, and the filter sheet 22 on the connecting skeleton 21 is completely unfolded, at this time, under the action of gravity, the water flow will flow from the filter sheet 22 to the water outlet pipe 4, and the flocculation is intercepted by the filter sheet 22, the water outlet pipe 4 is opened to discharge and collect the liquid, the connecting skeleton 21 near the connecting sheet 20 is provided with a first weakening portion 31, so that the connecting skeleton 21 first elastically deforms from the first weakening portion 31 under the action of an external force; When the flow rate at the water outlet pipe 4 is observed to be significantly smaller, it indicates that the flocculation blocks the filter sheet 22, at this time, the water outlet pipe 4 is closed, then the first motor 7 is started to move the plug rod 11 by the connecting rope 18, then the plug rod 11 is reset when the pulling force is removed, so as to realize the up-and-down reciprocating movement of the float 19 at the bottom of the plug rod 11 and the connecting sheet 20, this movement can make the connecting skeleton 21 drive the filter sheet 22 to extrude the filtered liquid at the bottom of the filter sheet 22 to make the liquid pass through the filter sheet 22 in the opposite direction, forming a backflushing cleaning effect on the filter sheet 22, cooperating with the bending deformation of the filter sheet 22 driven by the connecting skeleton 21, and the reverse impact of the water flow, the flocculation on the filter sheet 22 can be cleaned to a great extent, after the cleaning is completed, the water outlet pipe 4 is opened again to discharge the liquid, so as to ensure the efficient use of the filter sheet 22; After the liquid is discharged, the flocculation is concentrated at the bottom of the tank 1 near the baffle 23 under the action of gravity, and at the bottom of the float 19. At this time, the first motor 7 is started again to wind the connecting rope 18, so that the float 19 is driven by the insertion rod 11 to move towards the baffle 23. At this time, the float 19 and the connecting sheet 20 extrude the connecting framework 21 and the filter sheet 22 to deform, and the space between the float 19 and the baffle 23 becomes smaller. The flocculation in the space is extruded, and the volume of the flocculation is reduced, and the waste liquid inside is extruded and flows to the water outlet pipe 4 through the filter sheet 22 to be collected. This not only reduces the space occupation of the flocculation, but also further discharges the liquid, which is convenient for subsequent processing. After the extrusion operation is completed, the float 19 and the insertion rod 11 are moved upwards, so that the connecting framework 21 and the filter sheet 22 are unfolded again to release the extrusion of the flocculation. At this time, the flocculation outlet 5 is opened, the second motor 9 is started to rotate the stirring rod 12, the stirring sheet 13 hooks the connecting rod 29, the stirring rod 12 drives the connecting rod 29 to rotate, the connecting rod 29 drives the second supporting framework 26 and the separation sheet 28 below it and the first supporting framework 25 to rotate. In this way, the flocculation can be pushed towards the flocculation outlet 5 to assist the discharge and collection of the flocculation. By adjusting the position of the stirring sheet 13, the other side of the connecting rod 29 can be hooked out, so that the second supporting framework 26, the first supporting framework 25 and the separation sheet 28 are pushed in the opposite direction to push more flocculation out of the flocculation outlet 5. The cooperation between the structures facilitates the collection of the flocculation; The second supporting framework 26 and the first supporting framework 25 are both L-shaped, and are connected by rotating shafts at the nodes near the right angles. When the connecting framework 21 and the filter sheet 22 are folded by the float 19, the second supporting framework 26, the first supporting framework 25 and the separation sheet 28 installed thereon are folded together through the rotating shaft 27 and the rotating points. When the connecting framework 21 and the filter sheet 22 are unfolded, the separation sheet 28 installed on the first supporting framework 25 and the second supporting framework 26 is unfolded together. When the connecting rod 29 drives the separation sheet 28 to rotate, the connecting framework 21 fixedly connected with the separation sheet 28 drives the filter sheet 22 to rotate on the baffle 23. In this way, it is convenient to remove the flocculation adhered to the connecting framework 21 and the filter sheet 22 from the flocculation outlet 5, and it is also convenient to maintain the connecting framework 21 and the filter sheet 22.

[0035] Further, the floating block 19 and the connecting piece 20 are both upwardly protruding arc-shaped structures, the cross sections of the floating block 19 and the connecting piece 20 are circular, the water flow and the flocculation are guided, the flocculation is prevented from accumulating, the cavity 30 is formed between the connecting piece 20 and the filter piece 22, the connecting framework 21 and the filter piece 22 are bent and deformed towards the floating block 19, the connecting piece 20 and the connecting framework 21 are integrally formed, the stability of the integrally formed structure is good, the production and use are convenient, the connecting piece 20 and the connecting framework 21 are both made of rubber material, the rubber material has good deformation capacity, the filter piece 22 is made of polytetrafluoroethylene material, the polytetrafluoroethylene also has good deformation capacity, the cross section of the filter piece 22 is wave-shaped, the deformation capacity of the filter piece 22 is enhanced, meanwhile, the area of the filter piece 22 is larger, so that the filtering effect of the filter piece 22 on the flocculation is better, the filter piece 22 is inverted conical, the flocculation is prevented from accumulating on the filter piece 22, and the flocculation can more easily fall from the filter piece 22 under the action of gravity; The plug rod 11 and the spring 15 at the top of the floating block 19 limit the floating block 19, the density of the floating block 19 is far less than the density of the liquid in the tank body 1, so the floating block 19 has a tendency to move upward in the liquid in the tank body 1, when the liquid in the tank body 1 is stirred by the stirring rod 12 and the stirring piece 13, the water flow acts on the floating block 19, so that the floating block 19 can float up and down in the tank body 1, so that the water flow can be further mixed more fully.

[0036] The working principle of the technical scheme provided by the application is as follows: In use, the device is initially in a state in which the recesses on the partition 23 are in sealing contact with the float 19, the connecting rope 18 is wound to the maximum extent on the mounting block 8 and is in a state of tension, the insertion rod 11 is pressing the float 19 so that it is in close contact with the partition 23, the spring 15 is stretched and is in a state of elastic deformation, the connecting skeleton 21 and the filter sheet 22 are bent in the direction of the connecting piece 20 to avoid the insertion rod 11 and the float 19, and the top of the float 19 is limited by the insertion rod 11 and the spring 15. When the liquid is mixed, the inlet pipe 2 and the medicine inlet pipe 3 are opened to introduce the waste liquid and the liquid medicine, the outlet pipe 4 and the flocculation outlet 5 are closed, the second motor 9 is started, the rotating rod 10 drives the stirring rod 12 and the stirring sheet 13 to rotate together, and the liquid in the tank 1 and the liquid medicine are rapidly mixed. Since the density of the float 19 is much smaller than the density of the liquid, the float 19 has a tendency to move upward in the liquid, and the water flow will cause the float 19 to float up and down, further promoting the liquid to fully contact and react, and accelerating the generation of flocculation. In the filtration and separation stage, the first motor 7 is started to reverse, and the connecting rope 18 is loosened. At this time, the spring 15 and the connecting skeleton 21 and the filter sheet 22 are reset and are opened, and the filter sheet 22 is fully expanded. Under the action of gravity, the water flows through the filter sheet 22 to the outlet pipe 4, the flocculation is intercepted by the filter sheet 22, and the filtered liquid can be collected by opening the outlet pipe 4. If the flow rate at the outlet pipe 4 is observed to decrease significantly, it indicates that the filter sheet 22 is blocked by the flocculation and needs to be cleaned. After the outlet pipe 4 is closed, the first motor 7 is started to drive the connecting rope 18 to move the insertion rod 11, and then the insertion rod 11 is reset to form the up-and-down reciprocating motion of the float 19 and the connecting piece 20.The movement drives the connection framework 21 and the filter 22 to extrude the liquid at the bottom, so that the liquid reversely passes through the filter 22 to form a back flush, and the bending deformation of the filter 22 driven by the connection framework 21 and the water flow impact can greatly clean the flocculation on the filter 22, and after the cleaning is completed, the water outlet pipe 4 is opened again to discharge the liquid, so that the filter 22 can operate efficiently; after the liquid is discharged, the flocculation is concentrated at the bottom of the tank 1 close to the partition plate 23 and below the float 19 under the action of gravity; the first motor 7 is started to wind the connecting rope 18, so that the plug rod 11 drives the float 19 to move towards the partition plate 23, the float 19 and the connecting plate 20 extrude the connection framework 21 and the filter 22 to deform, at the same time, the space between the float 19 and the partition plate 23 is reduced, the flocculation is extruded, the volume is reduced, and the internal waste liquid is extruded out, flows to the water outlet pipe 4 through the filter 22 and is collected, which not only reduces the space occupation but also facilitates subsequent processing; after the extrusion is completed, the float 19 and the plug rod 11 are moved upwards to expand the connection framework 21 and the filter 22, so that the extrusion of the flocculation is released; the flocculation outlet 5 is opened and the second motor 9 is started, so that the stirring rod 12 drives the stirring plate 13 to hook the connecting rod 29 to rotate, and then drives the second supporting framework 26, the partition plate 28 and the first supporting framework 25 to rotate, so as to push the flocculation to the direction of the flocculation outlet 5 to assist in collection; the stirring plate 13 hooks the other side of the connecting rod 29, which can be reversely pushed to discharge more flocculation and improve the collection convenience; in addition, the second supporting framework 26 and the first supporting framework 25 are both L-shaped and connected through rotating shafts, when the float 19 is folded to the connection framework 21 and the filter 22, the second supporting framework 26, the first supporting framework 25 and the partition plate 28 are folded and collected; when the connection framework 21 and the filter 22 are expanded, the partition plate 28 is also expanded synchronously; when the connecting rod 29 drives the partition plate 28 to rotate, the connection framework 21 drives the filter 22 to rotate on the partition plate 23, which facilitates manual removal of the flocculation on the connection framework 21 and the filter 22 and facilitates maintenance operation.
