Description

Technical Field

[0001] The invention relates to the technical field of stirring devices, and in particular to a stirring device for a reaction kettle used for treating ternary precursor waste. Background Art

[0002] In the field of lithium-ion battery technology, the ternary nickel-cobalt-manganese cathode material is a new type of cathode material that has emerged in recent years. Its cost is much lower than that of traditional lithium cobalt oxide cathode materials, while its energy density is higher than that of lithium iron phosphate cathode materials. However, due to the influence of many process conditions, small-scale tests, pilot tests and even mass production workshops will inevitably have some products with unqualified indicators, namely, ternary precursor waste.

[0003] The prior art for treating ternary precursor waste includes taking nickel-cobalt-manganese ternary precursor waste and stirring and slurrying it with pure water to obtain a slurry. For the slurry in the first step, a sulfuric acid solution is continuously added to the slurry, and a stirring state is maintained during the addition of the sulfuric acid solution, so that the solid particles of the nickel-cobalt-manganese ternary precursor waste are slowly and evenly acidified in a stirring and weakly acidic environment.

[0004] However, some shortcomings occur during actual processing: as the slurry is made, the liquid level will gradually rise, while the position of the stirring device is fixed, which affects the mixing effect of the stirring device on the slurry. For example, if the stirring device is too high, air will be drawn into the slurry material liquid, affecting the reaction stability. If the stirring device is too low, it will make it difficult for the upper slurry to be quickly and evenly stirred and mixed. In addition, solid particles are easily accumulated at the bottom of the slurry material, and the solid particles at the bottom are limited in stirring, which ultimately affects the overall mixing effect. Therefore, the present application provides a reactor stirring device for ternary precursor waste treatment to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a reactor stirring device for treating ternary precursor waste to solve the existing problems.

[0008] It further includes a floating component, and the floating component includes a fixed pipe. The fixed pipe and the stirring blades are fixed in a detachable manner. When the height of the slurry liquid level in the inner tank changes, the fixed pipe drives the stirring blades to move axially along the driving rod, so that multiple groups of stirring blades maintain appropriate positions in the slurry at different liquid levels.

[0009] As a preferred embodiment of the present invention, the floating component further includes a convex ring fixedly connected to the fixed pipe. The stirring blade is fixedly connected to the fixed pipe through the convex ring. A first branch pipe is fixedly connected to the bottom of the inner wall of the reaction kettle body.

Multiple groups of fixed pipes, convex rings, and stirring blades form a floating pipe, which is limited and slides between the driving rod and the first branch pipe. A float is provided on the driving rod and is communicated with the floating pipe. A second notch and a hollow groove are opened in the fixed pipe. A second channel is opened in the stirring blade and is communicated with the second notch and the hollow groove. A plurality of first outlets communicated with the second channel are opened on the outer wall of the stirring blade.

[0010] As a preferred embodiment of the present invention, a first channel communicated with the second channel is opened in the stirring blade. The first channel is communicated with the hollow groove, and a plurality of sub-channels are further opened in the first channel. One end of each of the plurality of sub-channels is bent to form an annular channel, and the annular channel is communicated with the first channel.

[0011] As a preferred embodiment of the present invention, a movable groove is opened between the second channel and the plurality of first outlets. A movable plate is slidably connected in the movable groove. A plurality of second outlets corresponding to the number of the first outlets are opened on the movable plate. A reset member is provided on the side wall of the movable plate.

[0012] As a preferred embodiment of the present invention, an extension pipe is fixedly connected in the float. A plurality of sliding grooves are opened on the inner wall of the extension pipe. A plurality of limiting sliders corresponding to the number of the sliding grooves are fixedly connected to the bottom end of the driving rod. The bottom end of the driving rod and the extension pipe are slidably matched through the plurality of limiting sliders and the sliding grooves. The top end of the first branch pipe and the fixed pipe are slidably matched through a shaft body.

[0013] As a preferred embodiment of the present invention, a plurality of first notches are opened on the bottom wall of the float. The fixed pipe and the float are communicated through the plurality of first notches. A plurality of mounting grooves are opened on the bottom wall of the float, and detachable counterweight blocks are installed in the plurality of mounting grooves.

[0014] Flange plates are fixedly connected to multiple groups of the fixed pipes, and the multiple groups of flange plates are fixed through bolts.

[0015] As a preferred solution described in the present invention, wherein: the bottom end of the first branch pipe is fixedly connected to multiple groups of support parts, each group of support parts includes a connecting pipe fixed to the first branch pipe, and a second branch pipe fixed to the connecting pipe, the top end of the second branch pipe extends outward through the reactor body and is provided with a collecting bottle and a valve, and a sampling hole is opened at one end of the second branch pipe located in the inner tank.

[0016] As a preferred solution described in the present invention, wherein: a first rod body is fixedly connected in the fixed tube at the bottom end of the floating tube, the first rod body is inserted into the first branch pipe, the first branch pipe is communicated with the connecting pipe, and a transmission member is fixedly connected at the connection between the two; water outlet holes are opened on the outer walls of several connecting pipes, and second rod bodies are rotatably connected in several connecting pipes, several auxiliary blades are fixedly connected to the several second rod bodies, and the first rod body and several second rod bodies are transmission connected via a transmission member.

[0017] As a preferred solution described in the present invention, a second baffle is arranged between the first rod body and the connecting pipe, a first stopper is arranged at the top end of the first rod body, and the first stopper and a plurality of the second baffles form a closed space in the first branch pipe; the first rod body and the first stopper, as well as the first rod body and a plurality of the second baffles, are connected via an axle.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting up a floating component, the stirring blade can be maintained in a position near the middle of the material liquid. First, it can avoid the stirring blade being too high, which can easily draw air in during stirring, resulting in foam and splashing caused by gas mixing, thereby ensuring the stability of the reaction; second, it can avoid the stirring blade being too low, which can not effectively stir the middle of the material liquid, thereby helping to maintain the stirring and mixing effect.

[0020] By setting the stirring blades, the speed at which the material liquid is thrown out of the stirring blades can be limited, thereby avoiding the problem of excessive outflow of acidic solution due to fast stirring speed, and preventing the stirring blades from having no time to mix, resulting in the problem of excessive local concentration of mist acid; and the acidic solution discharge position and the stirring blades always remain at the same position, so when the acidic solution flows out, the stirring blades can stir and mix it as soon as possible, thereby avoiding the problem of untimely stirring contact, resulting in excessive local concentration, which is beneficial to improving the stable mixing effect; and the float collects the acidic solution first, avoiding the acidic solution from flowing down from a high place and causing splashing, and part of the acid liquid directly contacts the upper inner wall or other components of the container before mixing with the slurry, which not only causes waste of acid liquid, but also easily causes local corrosion or accelerates scaling.

[0021] By setting up the connecting pipe, the first branch pipe and the second branch pipe, the fluidity of the material liquid can be improved. At the same time, when the material flows out, it will impact the material liquid at the bottom of the inner tank, thus reducing the problem of particle accumulation and overly concentrated acid mist at the bottom. In addition, when solid particles in some waste materials enter the connecting pipe and are discharged, they will pass through multiple auxiliary blades. The multiple auxiliary blades can break up some solid particles and reduce the volume of the solid particles. When they are discharged from the connecting pipe into the inner tank, it is beneficial to accelerate the reaction rate between the solid particles and the acidic solution. Moreover, it is also convenient to carry out work such as sampling and testing of the material liquid. Since the heights of the multiple second branch pipes are different, different height sample material liquids can be taken when sampling through the second branch pipes.

[0042] The stirring device for treating ternary precursor waste in this embodiment includes a reaction kettle body 1 and a driving part 2 which are connected. A driving rod 3 and an inner tank 4 are arranged in the reaction kettle body 1. A plurality of groups of stirring blades 7 are arranged on the circumferential side wall of the driving rod 3. When the driving part 2 is started, it drives the plurality of groups of stirring blades 7 to rotate to stir the materials in the inner tank 4. The above structure is the prior art and will not be described in detail; it further includes a floating assembly. The floating assembly includes a fixed pipe 5. The fixed pipe 5 and the stirring blades 7 are fixed in a detachable manner. When the height of the slurry liquid level in the inner tank 4 changes, the fixed pipe 5 drives the stirring blades 7 to axially move along the driving rod 3, so that the plurality of groups of stirring blades 7 maintain a proper position in the slurry at different liquid levels.

[0043] The floating component further includes a convex ring 6 fixedly connected to the fixed pipe 5, and the stirring blade 7 is fixedly connected to the fixed pipe 5 through the convex ring 6; a first branch pipe 9 is fixedly connected to the inner bottom of the reaction kettle body 1, and the first branch pipe 9 and the driving rod 3 are on the same axis. A plurality of groups of fixed pipes 5, convex rings 6 and stirring blades 7 form a floating pipe, which is limited and slides between the driving rod 3 and the first branch pipe 9, and a float 8 communicating with the floating pipe is arranged on the driving rod 3; a second notch 16 and a hollow groove 17 are formed in the fixed pipe 5, a second channel 19 communicating with the second notch 16 and the hollow groove 17 is formed in the stirring blade 7, and a plurality of first outlets 23 communicating with the second channel 19 are formed on the outer wall of the stirring blade 7; a first channel 18 communicating with the second channel 19 is formed in the stirring blade 7, the first channel 18 communicates with the hollow groove 17, and a plurality of sub-channels 20 are further formed in the first channel 18. One end of each of the plurality of sub-channels 20 is bent to form an annular channel 21, and the annular channel 21 communicates with the first channel 18. An activity groove 22 is formed between the second channel 19 and the plurality of first outlets 23, an activity plate 24 is slidably connected in the activity groove 22, a plurality of second outlets 25 corresponding to the number of the first outlets 23 are formed on the activity plate 24, and a resetting member 26 is arranged on the side wall of the activity plate 24. The resetting member 26 is a spring or a magnetic structure.

[0044] By arranging the float assembly, when pure water and acidic solution are added into the inner tank 4, the liquid level of the mixed material liquid will gradually rise. During this process, the liquid level will drive the float 8 to rise, and the floating pipe at the bottom end of the float 8 slides on the first branch pipe 9, so that a plurality of groups of stirring blades 7 on the floating pipe move along with the float 8, and further the stirring blades 7 are maintained at a position near the middle in the material liquid. One is to avoid that the position of the stirring blade 7 is too high, which is easy to entrain air during stirring, resulting in problems such as foam and splashing caused by gas mixing, and ensuring stable reaction; the other is to avoid that the position of the stirring blade 7 is too low and it cannot effectively stir the middle part of the material liquid, which is beneficial to maintaining the stirring and mixing effect.

[0045] In use, waste materials and pure water are directly added into the inner tank 4, and the acidic solution is added into the float 8 through the pipe orifice above the inner tank 4. When the stirring blade 7 rotates, the acidic solution in the float 8 enters into a plurality of fixed pipes 5, and the material liquid located in the fixed pipes 5 enters into the hollow tank 17 through the second notch 16. Due to the action of rotational centrifugal force, the material liquid in the hollow tank 17 enters into the first channel 18 in the stirring blade 7. The advantage of such a setting is that during the rotation of the stirring blade 7, the centrifugal force causes the material liquid to flow in the first channel 18. During this process, a part of the material liquid in the first channel 18 continues to flow forward, and the other part flows back into the first channel 18 through the sub-channel 20 and the annular channel 21. Since the outflow direction in the annular channel 21 is different from the flow direction in the first channel 18, a certain resistance can be generated when the two material liquids collide, thereby restricting the speed at which the material liquid is thrown out in the stirring blade 7, and further avoiding the problem that too much acidic solution flows out due to a fast stirring speed, preventing the problem that the stirring blade 7 is too late to mix, resulting in too high a local concentration of fog acid. Moreover, the float 8 first collects the acidic solution, avoiding splashing caused by the acidic solution flowing down from a high place, and some acid liquid directly contacting the upper inner wall of the container or other components without being mixed with the slurry, which will not only cause waste of the acid liquid, but also easily cause local corrosion or accelerated scaling.

[0046] And the discharge position of the acidic solution and the stirring blade 7 always remain in the same position. Therefore, when the acidic solution flows out, the stirring blade 7 can perform stirring and mixing immediately, thus avoiding the problem of too high a local concentration caused by untimely stirring contact, which is beneficial to improving the stable mixing effect.

[0047] In addition, by providing the movable plate 24, a counterweight 12 is provided at one end of the movable plate 24. When the stirring blade 7 rotates following the floating cylinder, the centrifugal force causes the movable plate 24 in the stirring blade 7 to move to one side. During this process, the first outlet 23 and the second outlet 25 on the movable plate 24 are aligned, so that the acidic solution flows out. When the stirring blade 7 stops rotating, the centrifugal force gradually disappears, and the reset member 26 drives the movable plate 24 to reset, thereby continuously closing the first outlet 23 to prevent problems such as the acidic solution continuing to flow out after shutdown and affecting the detection accuracy; therefore, when the stirring blade 7 starts, the acidic solution can flow out, and when the stirring blade 7 stops decelerating, the acidic solution cannot flow out. In this way, it is not only beneficial to maintain the stirring state during the addition of the sulfuric acid solution, but also no additional structure control is required.

[0048] An extension tube 39 is fixedly connected inside the buoy 8, and a number of slide grooves 13 are provided on the inner wall of the extension tube 39. A limit slider 14 corresponding to the number of the slide grooves 13 is fixedly connected to the bottom end of the driving rod 3. The bottom end of the driving rod 3 and the extension tube 39 are slidably matched through a number of limit sliders 14 and the slide grooves 13, and the top of the first branch pipe 9 and the fixed tube 5 are slidably matched through the shaft body; a number of first notches 10 are provided on the bottom wall of the buoy 8, and the fixed tube 5 and the buoy 8 are connected through a number of first notches 10; a number of installation grooves 11 are provided on the bottom wall of the buoy 8, and detachable counterweights 12 are installed in the several installation grooves 11. The buoyancy of the buoy 8 can be adjusted by adding or reducing the counterweights 12, and since the several installation grooves 11 are annularly provided at the bottom of the buoy 8, the purpose of debugging dynamic balance can also be achieved by adjusting the position of the counterweight 12 to prevent problems such as displacement when the buoy 8 rotates.

[0049] Multiple groups of fixed pipes 5 are fixedly connected with flanges 15, and multiple groups of flanges 15 are fixed by bolts. The advantage of this arrangement is that the fixed pipes 5 can be increased or decreased as needed, so as to facilitate adjustment of the required length, and can be replaced separately when damaged, and it is also easier to clean the pipe wall after disassembly.

[0050] The bottom end of the first branch pipe 9 is fixedly connected to a plurality of support parts, each support part comprises a connecting pipe 34 fixed to the first branch pipe 9, and a second branch pipe 35 fixed to the connecting pipe 34. The top end of the second branch pipe 35 penetrates the reactor body 1 and extends outward, and is provided with a collecting bottle 37 and a valve 38. A sampling hole 36 is provided at one end of the second branch pipe 35 located in the inner tank 4. A first rod body 29 is fixedly connected to the fixed pipe 5 at the bottom end of the floating tube. The first rod body 29 is inserted into the first branch pipe 9. The first branch pipe 9 and the connecting pipe 34 are communicated, and a transmission member 30 is fixedly connected to the connection between the two. The transmission member 30 is a prior art, such as a gear box. Water outlet holes 33 are provided on the outer walls of the plurality of connecting pipes 34, and the second rod bodies 31 are rotatably connected in the plurality of connecting pipes 34. A plurality of auxiliary blades 32 are fixedly connected to the plurality of second rod bodies 31. The first rod body 29 and the plurality of second rod bodies 31 are transmission-connected via the transmission member 30.

[0051] Among them, the water outlet holes 33 are annularly arranged on the circumferential side wall of the connecting pipe 34, and there are multiple auxiliary vanes 32 on the first rod body 29. When the floating member rotates, it will drive the first rod body 29 to rotate, and through the transmission member 30 of the prior art, it drives several second rod bodies 31 to rotate, so that the auxiliary vanes 32 on the second rod bodies 31 rotate. The advantage of this setting is that the rotation of the multiple auxiliary vanes 32 generates attraction, so that the material liquid enters the second branch pipe 35 and the connecting pipe 34 in sequence through the sampling hole 36, and finally flows out through the annularly arranged water outlet holes 33. During this process, the fluidity of the material liquid can be improved. At the same time, when the material liquid flows out through the second branch pipe 35, it will impact the material liquid at the bottom of the inner tank 4, thereby reducing the problem of particle accumulation and too thick mist at the bottom; in addition, when solid particles in some waste materials enter the connecting pipe 34 and are discharged, they will pass through multiple auxiliary vanes 32, and the multiple auxiliary vanes 32 can break some solid particles and reduce the volume of the solid particles. When it is discharged from the connecting pipe 34 into the inner tank 4, it is beneficial to accelerate the reaction rate between the solid particles and the acidic solution.

[0052] During sampling, the valve 38 is opened. During this process, the sampling hole 36 on the second branch pipe 35 in the inner tank 4 allows the material liquid to flow into the collection bottle 37, which is convenient for sampling and detecting the material liquid. Since the heights of the multiple second branch pipes 35 are different, different heights of sample material liquid can be taken when sampling through the second branch pipe 35, which is further convenient for sampling and detecting work.

[0053] A second baffle 28 is provided between the first rod body 29 and the connecting pipe 34, and a first stop block 27 is provided at the top of the first rod body 29. The first stop block 27 and several second baffles 28 form a closed space in the first branch pipe 9 to prevent materials from entering the closed space, which can better discharge the materials in the connecting pipe 34, and at the same time to prevent the transmission member 30 from being affected.

[0054] Both between the first rod body 29 and the first stop block 27 and between the first rod body 29 and several second baffles 28 are connected by a shaft body.

[0055] The shaft bodies appearing in this article are all products of the prior art, having the functions of sliding and sealing, and each structure in the inner tank 4 has corrosion resistance, such as coatings, materials, etc. This is the prior art and will not be elaborated in detail.

[0056] Working principle: During use, waste materials and pure water are directly added into the inner tank 4, and the acidic solution is added into the float 8 through the pipe orifice above the inner tank 4. When the stirring blade 7 rotates, the acidic solution in the float 8 enters into multiple fixed pipes 5, and the material liquid located in the fixed pipes 5 enters into the hollow tank 17 through the second notch 16. Due to the action of rotational centrifugal force, the material liquid in the hollow tank 17 enters into the first channel 18 inside the stirring blade 7. During the rotation process of the stirring blade 7, the centrifugal force causes the material liquid to flow in the first channel 18. During this process, a part of the material liquid in the first channel 18 continues to flow forward, and another part flows back into the first channel 18 through the branch channel 20 and the annular channel 21. Since the outflow direction in the annular channel 21 is different from the flowing direction in the first channel 18, a certain resistance can be generated when the two material liquids collide, thereby restricting the speed at which the material liquid is thrown out in the stirring blade 7.

[0057] Moreover, when the floating member rotates, it will drive the first rod 29 to rotate, causing the secondary blades 32 on the second rod 31 to rotate. The rotation of the multiple secondary blades 32 generates attraction, causing the material liquid to sequentially enter the second branch pipe 35 and the connecting pipe 34 through the sampling holes 36, and finally flow out through the annularly arranged water outlet holes 33. At the same time, when the material liquid flows out through the second branch pipe 35, it will impact the material liquid at the bottom of the inner tank 4, thereby reducing the problems of particle accumulation and excessive fog acid concentration at the bottom; in addition, when solid particles in some waste materials enter the connecting pipe 34 and are discharged, they will pass through the multiple secondary blades 32, and the multiple secondary blades 32 can break up some solid particles, reducing the volume of the solid particles and improving the contact and mixing effect.

[0058] The present invention covers any substitutions, modifications, equivalent methods, and solutions made within the essence and scope of the present invention. To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention even without these detailed descriptions. Additionally, to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0059] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
