Description

Technical Field

[0001] This utility model relates to the field of new energy material production technology, specifically to a mother liquor recycling and rinsing system for the synthesis process of new energy materials. Background Technology

[0002] With the rapid growth of global demand for clean energy, the new energy materials industry, especially the production of ternary precursors, occupies a crucial position in the entire new energy industry chain. As a key raw material for ternary lithium batteries, the production scale of ternary precursors is continuously expanding to meet the increasing market demand. However, the current production process faces severe cost control challenges, which seriously restrict the economic benefits of enterprises and the sustainable development of the industry.

[0003] In the synthesis process, the treatment of the mother liquor becomes a major challenge. The mother liquor contains a large amount of incompletely reacted metals, such as various metal ions and fine precursor particles. Because existing filtration technologies are insufficient to effectively intercept these minute substances, the metals in the mother liquor cannot be efficiently reused when it enters the wastewater treatment process. This not only results in a significant waste of metal resources and increases raw material procurement costs, but also significantly increases the difficulty and cost of wastewater treatment. For example, traditional wastewater treatment processes require the use of large amounts of chemical agents to neutralize and precipitate metal ions in the mother liquor, and the treatment process often consumes a large amount of energy to ensure that the wastewater meets discharge standards. In the long run, this undoubtedly places a heavy economic burden on enterprises.

[0004] Meanwhile, blockages in slurry pipelines and valves have also caused numerous production problems. To effectively address this issue, existing technology necessitates flushing the slurry pipelines with large amounts of pure water after slag discharge. While this flushing method can ensure pipeline unobstructed flow to some extent, it results in persistently high pure water consumption. This high pure water consumption undoubtedly further exacerbates the company's operating costs. Moreover, the extensive use of pure water for flushing can generate substantial wastewater, requiring additional treatment costs and further squeezing the company's profit margins.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a mother liquor recycling and rinsing system for the synthesis process of new energy materials.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mother liquor recycling and rinsing system for the synthesis process of new energy materials includes: At least one slurry tank having a slurry trough; Slurry storage tank, which has a slurry storage tank; At least one first transfer pipe, wherein the slurry storage tank is connected to each of the slurry tanks through each of the first transfer pipes; The second transfer pipe connects the outer space of the slurry storage tank to the slurry storage trough; Multiple pure water rinsing pipes, wherein the first material transfer pipe and the second material transfer pipe are both connected to one of the pure water rinsing pipes; Mother liquor tank, with mother liquor trough; A mother liquor inlet pipe is used to transfer the mother liquor produced in the synthesis process into the mother liquor tank; The main mother liquor pipeline is connected to the mother liquor tank; Multiple branch mother liquor pipelines are all connected to the main mother liquor pipeline, and the first transfer pipeline and the second transfer pipeline are both connected to one of the branch mother liquor pipelines.

[0008] Taking a slurry tank as an example, it could also be a slurry bucket, slurry box, etc.

[0009] The following example uses the first material transfer pipe: The slurry generated in the synthesis process is first stored in a slurry tank as a temporary storage tank. After the slurry in the slurry tank reaches the full liquid level, the slurry in the slurry tank needs to be transferred to the slurry storage tank through the first transfer pipe. Since the slurry is a solid-liquid mixture containing solid particles, the first transfer pipe needs to be flushed after each use. This flushes the remaining solid particles in the first transfer pipe into the slurry storage tank to prevent pipe blockage. Based on the initial process design of the production line, in order to ensure that no other impurities and foreign objects are introduced during the rinsing process, the existing rinsing method is to use pure water to rinse the pipeline and input pure water into the first transfer pipeline for cleaning. The consumption of pure water is large and the cleaning cost is high. This application uses a branch mother liquor pipeline to input the mother liquor generated in the synthesis process into the first transfer pipeline to replace pure water for cleaning. The same cleaning effect can be achieved. Moreover, using the mother liquor generated in the synthesis process does not require a large investment in cleaning raw materials. By reducing or even avoiding the use of pure water, the cleaning cost can be reduced. In addition, the mother liquor produced in the synthesis process contains unreacted and unfilterable metal materials (such as metal ions, precursor fine particles, etc.). By cleaning the first transfer pipe with the mother liquor, it is reintroduced into the slurry system of the synthesis system. The aforementioned metal materials will recrystallize into filterable solid particles under alkaline slurry conditions and eventually become the product. This realizes the recycling of metal materials in the mother liquor, reduces the cost of mother liquor treatment, and improves the economic efficiency and environmental friendliness of new energy material production.

[0010] One end of the second transfer pipe is connected to the slurry storage tank, and the other end is connected to the material filtration and washing equipment of the washing process after the synthesis process for further processing of the slurry.

[0011] Each of the first transfer pipes can be connected to the same third transfer pipe, which in turn connects to the slurry storage tank.

[0012] The branch mother liquor pipeline connected to the second transfer pipeline can be integrated with the main mother liquor pipeline. In this case, the branch mother liquor pipeline can be regarded as part of the main mother liquor pipeline.

[0013] In a further technical solution, both the first transfer pipe and the second transfer pipe are connected to the corresponding branch mother liquor pipe through the corresponding pure water flushing pipe.

[0014] In one scenario, for example, both the branch mother liquor pipeline and the pure water flushing pipeline are directly connected to the first transfer pipeline. Compared to this method, using the pure water flushing pipeline as an intermediate pipeline between the first transfer pipeline and the branch mother liquor pipeline, i.e., the pure water flushing pipeline is still connected to the first transfer pipeline, while the branch mother liquor pipeline is actually connected to the pure water flushing pipeline, can reduce the overall pipeline length and thus reduce structural costs.

[0015] In a further technical solution, the pure water rinsing pipeline is provided with a first control valve and a second control valve, and the connection point between the branch mother liquor pipeline and the corresponding pure water rinsing pipeline is set as a first contact point, which is located between the corresponding first control valve and the corresponding second control valve. A third control valve is installed on the branch mother liquor pipeline.

[0016] How to adjust the opening degree of the control valve is a current technology. If it is used in conjunction with an existing control system (such as a PLC control system), it will not be elaborated here.

[0017] For example, the connection point between the pure water flushing pipe and the first transfer pipe is set as the second contact point. The first control valve is located between the first contact point and the second contact point, which can simultaneously control the flow of pure water in the pure water flushing pipe and the flow of mother liquor in the branch mother liquor pipe. In conjunction with the second control valve and the third control valve, dual protection control of the fluid is achieved.

[0018] In some implementations, a conductivity sensor (with simultaneous conductivity and flow rate monitoring functions) is installed on the main mother liquor pipeline to monitor the stability of the metal molten material returning to the mother liquor rinse water and its impact on product quality in real time. To ensure that the mother liquor rinse water does not negatively affect product quality after entering the slurry system, it is necessary to combine the data from previous verification, determine the amount of microporous material in the mother liquor rinse water that can enter the system daily based on the daily output, and set up a PLC interlock. Real-time data monitoring is performed through online conductivity sensors and flow rates, and the opening of the third control valve is automatically adjusted to ensure that the amount of microporous material in the mother liquor rinse water entering the unit slurry is consistent and controllable. Through valve control and real-time monitoring, the automation and stability of the mother liquor rinsing process are ensured, significantly reducing the cost of pure water consumption and wastewater (mother liquor) treatment, and improving the economic and environmental benefits of new energy material production.

[0019] In a further technical solution, the first control valve and the third control valve are automatic valves; the second control valve is a manual valve, and the second control valve is simultaneously located on the corresponding pure water flow path and the corresponding mother liquor flow path.

[0020] The pure water flushing pipeline is divided into two sections. One section (the first section) is connected to the existing pure water flushing system to supply pure water flow, and the other section (the second section) supplies pure water and mother liquor flow. The second control valve is located in the second section.

[0021] Under normal circumstances, the first control valve controls the flow of pure water in the first section, the third control valve controls the flow of mother liquor in the branch mother liquor pipeline, and the second control valve is not used. When it is necessary to control the flow of pure water and mother liquor simultaneously, the second control valve can be used, or if either the first or third control valve fails, the second control valve can be used for control.

[0022] The first and third control valves require rapid control, so they are automatic valves. The second control valve can be considered a backup valve, so it is a manual valve. This reduces costs and prevents its failure from affecting the flow of pure water and mother liquor.

[0023] A further technical solution involves configuring multiple slurry tanks, arranged side-by-side with intervals between them. This configuration improves the utilization rate of the slurry storage tanks. It should be noted that if the slurry tanks are arranged arbitrarily, it will lead to difficulties in the layout of the first transfer pipe, etc., which is not conducive to ensuring the smooth flow of related fluids.

[0024] A further technical solution involves assembling a slurry tank group, with the slurry storage tank aligned with the central region of the slurry tank group. This arrangement minimizes the length difference between the first transfer pipes when the slurry storage tank is fluidly connected to each slurry tank via the first transfer pipes. The central region is located in the middle section between the two end slurry tanks in the arrangement direction of the slurry tanks, and the average distance from this location to each slurry tank is less than its distance to the end slurry tanks of the slurry tank group. This reduces the total material consumption of each first transfer pipe, lowering equipment manufacturing and installation costs.

[0025] A further technical solution is that one end of the first transfer pipe passes through the bottom of the corresponding slurry tank, and the other end passes through the top of the slurry storage tank; The second transfer pipe passes through the bottom of the slurry storage tank; The mother liquor inlet pipe extends through the top of the mother liquor tank; The main mother liquor pipeline runs through the bottom of the mother liquor tank.

[0026] The configuration in this section facilitates the flow of the relevant fluids. For example, one end of the first transfer pipe passes through the bottom of the corresponding slurry tank, making it convenient for the slurry in the slurry tank to flow out through the first transfer pipe, and the other end of the first transfer pipe passes through the top of the slurry storage tank, making it convenient for the slurry in the slurry tank to be transferred into the slurry storage tank.

[0027] Taking the main mother liquor pipeline as an example, the main mother liquor pipeline can also penetrate the bottom of the side wall of the mother liquor tank, ensuring smooth flow of the mother liquor and avoiding the need for openings at the bottom of the mother liquor tank. It can also utilize existing pump structures to assist in fluid transfer, which will not be elaborated upon here. When using existing pump structures, the main mother liquor pipeline can be divided into two sections: one section connects to the mother liquor tank and the pump structure, and the other section connects to the pump structure and the branch mother liquor pipelines.

[0029] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0031] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0033] The working principle and advantages of this utility model are as follows: The slurry generated in the synthesis process is first stored in a slurry tank as a temporary storage tank. Once the slurry in the tank reaches full level, it needs to be transferred entirely into a slurry storage tank via a first transfer pipe. Since the slurry is a solid-liquid mixture containing solid particles, the first transfer pipe needs to be flushed after each use to remove any remaining solid particles and transfer them into the slurry storage tank, preventing blockage. Based on the initial process design of this production line, to ensure that no impurities or foreign matter are introduced during the flushing process, the current flushing method uses pure water to clean the first transfer pipe. This consumes a large amount of pure water, resulting in high cleaning costs.

[0034] This application uses a branch mother liquor pipeline to input the mother liquor generated in the synthesis process into the first transfer pipeline to replace pure water for cleaning. The same cleaning effect can be achieved. Moreover, using the mother liquor generated in the synthesis process does not require a large investment in cleaning raw materials. By reducing or even avoiding the use of pure water, the cleaning cost can be reduced.

[0035] In addition, the mother liquor produced in the synthesis process contains unreacted and unfilterable metal materials (such as metal ions, precursor fine particles, etc.). By cleaning the first transfer pipe with the mother liquor, the mother liquor can be reintroduced into the slurry system of the synthesis system. During this process, the aforementioned metal materials will recrystallize into filterable solid particles under alkaline slurry conditions to eventually become the product. This realizes the recycling of metal materials in the mother liquor, reduces the cost of mother liquor treatment, and improves the economic efficiency and environmental friendliness of new energy material production.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0039] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0040] See Figure 1 A mother liquor recycling and rinsing system for the synthesis process of new energy materials includes: At least one slurry tank 1, having a slurry trough 11; Slurry storage tank 2, having slurry storage tank 21; At least one first transfer pipe 3, the slurry storage tank 21 is connected to each of the slurry tanks 11 through each of the first transfer pipes 3; The second transfer pipe 4 connects the outer space of the slurry storage tank 2 to the slurry storage tank 21; Multiple pure water rinsing pipes 5, the first material transfer pipe 3 and the second material transfer pipe 4 are both connected to one of the pure water rinsing pipes 5; Mother liquor tank 6, with mother liquor trough 61; Mother liquor inlet pipe 7 is used to transfer the mother liquor produced in the synthesis process into the mother liquor tank 61; The main mother liquor pipeline 8 is connected to the mother liquor tank 61; Multiple branch mother liquor pipes 9 are all connected to the main mother liquor pipe 8, and the first transfer pipe 3 and the second transfer pipe 4 are both connected to one of the branch mother liquor pipes 9.

[0041] Taking slurry tank 1 as an example, it can also be slurry bucket, slurry box, etc.

[0042] The following example uses the first material transfer pipe 3 as an illustration: The slurry generated in the synthesis process is first stored in the slurry tank 11 as a temporary storage tank. After the slurry in the slurry tank 11 reaches the full liquid level, the slurry in the slurry tank 11 needs to be transferred to the slurry storage tank 21 through the first transfer pipe 3 for storage. Since the slurry is a solid-liquid mixture containing solid particles, the first transfer pipe 3 needs to be flushed after each use. The solid particles remaining in the first transfer pipe 3 are flushed into the slurry storage tank 21 to avoid pipe blockage. Based on the initial process design of the production line, in order to ensure that no other impurities and foreign objects are introduced during the rinsing process, the existing rinsing method is to use pure water rinsing pipe 5 to input pure water into the first transfer pipe 3 for cleaning. The consumption of pure water is large and the cleaning cost is high. In this embodiment, the mother liquor produced in the synthesis process is input into the first transfer pipe 3 through the branch mother liquor pipe 9 to replace pure water for cleaning. The same cleaning effect can be achieved. Moreover, the mother liquor produced in the synthesis process does not require a large amount of cleaning raw material cost. The cleaning cost is reduced by reducing or even avoiding the use of pure water. In addition, the mother liquor produced in the synthesis process contains unreacted and unfilterable metal liquid (such as metal ions, precursor fine particles, etc.). By cleaning the first transfer pipe 3 with mother liquor, the mother liquor can be reintroduced into the slurry system of the synthesis system. During this process, the aforementioned metal liquid will recrystallize into filterable solid particles under alkaline slurry conditions to eventually become the product, realizing the recycling of metal liquid in the mother liquor, reducing the cost of mother liquor treatment, and improving the economy and environmental protection of new energy material production.

[0043] One end of the second transfer pipe 4 is connected to the slurry storage tank 21, and the other end is connected to the material filtration and washing equipment of the washing process after the synthesis process for further processing of the slurry.

[0044] Each of the first transfer pipes 3 can be connected to the same third transfer pipe, and the third transfer pipe is connected to the slurry storage tank 21.

[0045] The branch mother liquor pipeline 9, which is connected to the second transfer pipeline 4, can be integrated with the main mother liquor pipeline 8. In this case, the branch mother liquor pipeline 9 can be regarded as part of the main mother liquor pipeline 8.

[0046] In this embodiment, both the first transfer pipe 3 and the second transfer pipe 4 are connected to the corresponding branch mother liquor pipe 9 through the corresponding pure water flushing pipe 5.

[0047] In one scenario, for example, both the branch mother liquor pipe 9 and the pure water flushing pipe 5 are directly connected to the first transfer pipe 3. Compared to this method, the pure water flushing pipe 5 serves as an intermediate pipe between the first transfer pipe 3 and the branch mother liquor pipe 9. That is, the pure water flushing pipe 5 is still connected to the first transfer pipe 3, while the branch mother liquor pipe 9 is actually connected to the pure water flushing pipe 5. This can reduce the overall length of the pipes and thus reduce structural costs.

[0048] In this embodiment, the pure water flushing pipe 5 is provided with a first control valve 100 and a second control valve 200, and the connection point between the branch mother liquor pipe 9 and the corresponding pure water flushing pipe 5 is set as a first contact point 300, which is located between the corresponding first control valve 100 and the corresponding second control valve 200. The branch mother liquor pipeline 9 is equipped with a third control valve 400.

[0049] How to adjust the opening degree of the control valve is a current technology. If it is used in conjunction with an existing control system (such as a PLC control system), it will not be elaborated here.

[0050] For example, the connection point between the pure water flushing pipe 5 and the first transfer pipe 3 is set as the second contact point. The first control valve 100 is located between the first contact point 300 and the second contact point, which can simultaneously control the flow of pure water in the pure water flushing pipe 5 and the flow of mother liquor in the branch mother liquor pipe 9. In conjunction with the second control valve 200 and the third control valve 400, dual protection control of the fluid is achieved.

[0051] In some embodiments, a conductivity sensor 500 (with simultaneous conductivity and flow rate monitoring functions) is installed on the main mother liquor pipeline 8 to monitor in real time the stability of the metal molten metal returning to the mother liquor rinse water and its impact on product quality. To ensure that the mother liquor rinse water does not negatively affect product quality after entering the slurry system, it is necessary to combine the data from previous verification, determine the amount of microporous material in the mother liquor rinse water that can enter the system daily based on the daily output, and set up a PLC interlock. Real-time data monitoring is performed through the online conductivity sensor 500 and flow rate, and the opening of the third control valve 400 is automatically adjusted to ensure that the amount of microporous material in the mother liquor rinse water entering the unit slurry is consistent and controllable. Through valve control and real-time monitoring, the automation and stability of the mother liquor rinsing process are ensured, significantly reducing the cost of pure water consumption and wastewater (mother liquor) treatment, and improving the economic and environmental benefits of new energy material production.

[0052] In this embodiment, the first control valve 100 and the third control valve 400 are automatic valves; the second control valve 200 is a manual valve, and the second control valve 200 is simultaneously located on the corresponding pure water flow path and the corresponding mother liquor flow path.

[0053] The pure water flushing pipeline 5 is divided into two sections. One section (the first section) is connected to the existing pure water flushing system to supply pure water flow, and the other section (the second section) supplies pure water and mother liquor flow. The second control valve 200 is located in the second section.

[0054] Under normal circumstances, the first control valve 100 controls the flow of pure water in the first section, the third control valve 400 controls the flow of mother liquor in the branch mother liquor pipeline 9, and the second control valve 200 is not used. When it is necessary to control the flow of pure water and mother liquor simultaneously, the second control valve 200 can be used, or if either the first control valve 100 or the third control valve 400 fails, the second control valve 200 can also be used for control.

[0055] The first control valve 100 and the third control valve 400 require rapid control, therefore automatic valves are used. The second control valve 200 can be considered a backup valve, therefore a manual valve is used. This reduces costs and prevents disruption of the flow of pure water and mother liquor in case of malfunction. The specific type of automatic or manual valve is not limited, as long as it meets the above objectives.

[0056] In this embodiment, multiple slurry tanks 1 are configured, arranged side-by-side with intervals between them. This arrangement improves the utilization rate of the slurry storage tank 2. It should be noted that if the slurry tanks 1 are arranged arbitrarily, it will lead to difficulties in the arrangement of the first transfer pipe 3, etc., which is not conducive to ensuring the smooth flow of related fluids.

[0057] In this embodiment, the slurry tanks form a slurry tank group, and the slurry storage tank 2 is aligned with the central region of the slurry tank group. This arrangement minimizes the length difference between the first transfer pipes 3 when the slurry storage tank 2 is in fluid communication with each slurry tank 1 via the first transfer pipes 3. The central region is the middle section located between the two end slurry tanks 1 in the arrangement direction of the slurry tanks 1, and the average distance from this position to each slurry tank 1 is less than its distance to the two end slurry tanks 1 of the slurry tank group. This reduces the total material consumption of each first transfer pipe 3, lowering equipment manufacturing and installation costs.

[0058] In this embodiment, one end of the first transfer pipe 3 passes through the bottom of the corresponding slurry tank 1, and the other end passes through the top of the slurry storage tank 2; The second transfer pipe 4 passes through the bottom end of the slurry storage tank 2; The mother liquor inlet pipe 7 passes through the top of the mother liquor tank 6; The main mother liquor pipeline 8 passes through the bottom end of the mother liquor tank 6.

[0059] The arrangement in this section facilitates the flow of the relevant fluids. For example, one end of the first transfer pipe 3 passes through the bottom of the corresponding slurry tank 1, which makes it convenient for the slurry in the slurry tank 11 to flow out through the first transfer pipe 3. The other end of the first transfer pipe 3 passes through the top of the slurry storage tank 2, which makes it convenient for the slurry in the slurry tank 11 to be transferred into the slurry storage tank 21.

[0060] Taking the main mother liquor pipeline 8 as an example, the main mother liquor pipeline 8 can also penetrate the bottom of the side wall of the mother liquor tank 6, which can also ensure the smooth flow of mother liquor and avoid opening holes at the bottom of the mother liquor tank 6. It can also be assisted by the existing pump structure 600 (not limited) for fluid transfer, which will not be elaborated here. When using the existing pump structure 600, the main mother liquor pipeline 8 can be divided into two sections: one section is connected to the mother liquor tank 6 and the pump structure 600, and the other section is connected to the pump structure 600 and the branch mother liquor pipeline 9.

[0061] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
