Description

Technical Field

[0001] The present application relates to the technical field of ammonium phosphate production equipment, and in particular to an operating device for a battery ammonium phosphate crystallizer. Background Art

[0002] Lithium-ion batteries are an important energy storage solution widely used in mobile electronic devices, electric vehicles and energy storage systems. Battery-grade monoammonium phosphate (i.e. ammonium phosphate) plays a key role in the production of positive electrode materials for lithium-ion batteries. As a provider of phosphate, it is one of the main raw materials for the preparation of positive electrode material precursors. In recent years, with the rapid growth of new energy vehicles and renewable energy markets, the demand for lithium-ion batteries has exploded.

[0003] However, there is a serious problem in the production process of battery-grade monoammonium phosphate, that is, the frequent failure of the crystallizer leads to production interruption, increased maintenance costs, and reduced production continuity. The existing technology fails to effectively solve this problem, which poses a serious challenge to the reliability and economic benefits of the device.

[0004] Traditional battery-grade monoammonium phosphate production equipment usually adopts the "neutralization, crystallization, centrifugal drying" process, in which the crystallization process is the key step in the production process. The crystallizer plays a core role in this process and determines key indicators such as product quality, output, and cost. Therefore, solving the problem of crystallizer failure is crucial to improving the start-up rate and load rate of the device, reducing energy consumption, maintenance costs, and reducing labor intensity.

[0005] To address this technical challenge, the present application provides a practical and effective device to solve the problem of crystallizer failure, ensure that the battery-grade monoammonium phosphate production device can operate stably for a long period of time, significantly reduce production costs, and improve economic benefits.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1 and Figure 2 The present application first provides an embodiment of a battery ammonium crystallizer operating device, which includes:

[0033] A crystallizer 01, B crystallizer 02, C crystallizer 03, D crystallizer 04, E crystallizer 05, F crystallizer 06, crystallizer main pipe 07, crystallizer branch pipe 08, first discharge pipe assembly 09 and second discharge pipe assembly 10. The A crystallizer 01, B crystallizer 02, C crystallizer 03, D crystallizer 04, E crystallizer 05 and F crystallizer 06 are connected to the crystallizer main pipe 07 through the corresponding crystallizer branch pipe 08 respectively, the B crystallizer 02 and the C crystallizer 03 are connected to the centrifuge through the first discharge pipe assembly 09, and the D crystallizer 04, E crystallizer 05 and F crystallizer 06 are connected to the centrifuge through the second discharge pipe assembly 10.

[0034] In the crystallizers provided in this embodiment, A crystallizer 01, B crystallizer 02, C crystallizer 03, D crystallizer 04, E crystallizer 05, F crystallizer 06 are six different crystallizer units, each of which is used for a specific crystallization task or stage.

[0035] The crystallizer main pipe 07 is a pipe or channel for connecting six crystallizers together to form an integrated crystallization system. It connects the crystallizer branch pipes 08 from the A crystallizer 01 to the F crystallizer 06 together.

[0036] The crystallizer branch pipe 08 is a branch pipeline used to connect each crystallizer to the crystallizer main pipe 07. Each crystallizer is connected to the crystallizer main pipe 07 through the corresponding crystallizer branch pipe 08 to control and adjust the operation of each crystallizer.

[0037] The first discharge pipe assembly 09 connects the B crystallizer 02 and the C crystallizer 03 to the centrifuge. The products of the B crystallizer 02 and the C crystallizer 03 will pass through the first discharge pipe assembly 09 and enter the centrifuge for the next step of processing or separation.

[0038] Second discharge pipe assembly 10: This is another assembly that connects the D crystallizer 04, E crystallizer 05 and F crystallizer 06 to the centrifuge. This means that the products of the D crystallizer 04, E crystallizer 05 and F crystallizer 06 will pass through the second discharge pipe assembly 10 into the centrifuge, and may undergo different treatments or separation steps.

[0039] Working process:

[0040] First, the liquid or solution enters each crystallizer through the feed pipe on each crystallizer, and then enters the system from the crystallizer main pipe 07. Then, through the crystallizer branch pipe 08, this fluid can be distributed to six different crystallizer units: A, B, C, D, E, and F crystallizers 06. After the products flow out of different crystallizers, the products of B and C crystallizers 03 enter the centrifuge through the first discharge pipe assembly 09, while the products of D, E, and F crystallizers 06 enter the centrifuge through the second discharge pipe assembly 10.

[0041] In a centrifuge, separation, concentration or other processing steps may be performed to isolate the desired crystals or products. The function of a centrifuge is to separate particles or liquid components based on differences in the density of the substances.

[0042] The principle of this battery ammonium crystallizer operation device is based on the concept of a multi-crystallizer system. Through the precise control of the crystallizer branch pipe 08 and the main pipe, the fluid can be directed to different crystallizers. Then, through the use of centrifuges, the product can be further processed and separated to obtain the desired final product.

[0043] The multi-crystallizer system and automated control can reduce the workload of operators and reduce the need for manual operation, thereby reducing the intensity of manual labor. Each crystallizer can operate independently, making it easier to manage and maintain. If one crystallizer needs maintenance or fails, the other crystallizers can still continue production.

[0044] In an optional embodiment, the first discharge pipe assembly 09 includes a first discharge pipe 11 and a second discharge pipe 12 , the B crystallizer 02 is connected to the centrifuge via the first discharge pipe 11 , and the C crystallizer 03 is connected to the centrifuge via the second discharge pipe 12 .

[0045] In this optional embodiment, the configurations of the first discharge pipe assembly 09 and the second discharge pipe assembly 10 are slightly changed, and the first discharge pipe 11 is a pipeline that guides the product from the B crystallizer 02 to the centrifuge. This means that the product of the B crystallizer 02 directly enters the centrifuge through the first discharge pipe 11 for processing.

[0046] The second discharge pipe 12 is another pipe that guides the product from the C crystallizer 03 to the centrifuge. This means that the product of the C crystallizer 03 directly enters the centrifuge through the second discharge pipe 12 for processing.

[0047] In this optional embodiment, the products of crystallizer B 02 and crystallizer C 03 can enter the centrifuge through independent discharge pipes. Such a configuration allows more flexible control of the flow and treatment of the products of crystallizer B 02 and crystallizer C 03.

[0048] In an optional embodiment, the second discharge pipe assembly 10 includes a third discharge pipe 13, a fourth discharge pipe 14 and a fifth discharge pipe 15, the D crystallizer 04 is connected to the centrifuge through the third discharge pipe 13, the E crystallizer 05 is connected to the centrifuge through the fourth discharge pipe 14, and the F crystallizer 06 is connected to the centrifuge through the fifth discharge pipe 15.

[0049] In this optional embodiment, the third discharge pipe 13 is a pipeline that guides the product from the D crystallizer 04 to the centrifuge. This means that the product of the D crystallizer 04 directly enters the centrifuge through the third discharge pipe 13 for processing.

[0050] The fourth discharge pipe 14 is another pipe that guides the product from the E crystallizer 05 to the centrifuge. This means that the product of the E crystallizer 05 directly enters the centrifuge through the fourth discharge pipe 14 for processing.

[0051] The fifth discharge pipe 15 is the third pipeline, which guides the product from the F crystallizer 06 to the centrifuge. This means that the product of the F crystallizer 06 directly enters the centrifuge through the fifth discharge pipe 15 for processing.

[0052] This optional embodiment further increases flexibility by allowing the flow and treatment of the products of the D, E and F crystallizers 06 to be controlled separately. The products of each crystallizer enter the centrifuge through independent discharge pipes to meet specific treatment and separation requirements. This configuration may be used for specific process requirements to ensure that the products of different crystallizers can be treated according to independent requirements.

[0053] In an optional embodiment, a valve 16 is provided on the crystallizer branch pipe 08 connected to each crystallizer, and a valve 16 is provided on each discharge branch pipe and the main pipe.

[0054] In this optional embodiment, a valve 16 is provided on each crystallizer branch pipe 08 connected to the crystallizer. This means that each crystallizer branch pipe 08 can be controlled and adjusted by the valve 16 to manage the distribution and flow direction of the fluid. This configuration increases the controllability and fine adjustment capability of the system.

[0055] In an optional embodiment, the first discharge pipe 11 is provided with a first discharge branch pipe 17 , and is connected to the C crystallizer 03 .

[0056] A valve 16 is provided on the crystallizer branch pipe 08 connected to each crystallizer, which means that the flow rate, pressure and flow direction of each crystallizer can be independently controlled to adapt to different crystallization conditions or requirements.

[0057] In addition to the valve 16 of the crystallizer branch pipe 08, each discharge branch pipe (the first discharge pipe 11, the second discharge pipe 12, the third discharge pipe 13, the fourth discharge pipe 14, and the fifth discharge pipe 15) is also provided with a valve 16. This makes it possible to precisely control the flow direction of the product, and to choose to direct it to a centrifuge or other processing equipment, or to divert it to different channels.

[0058] Main pipe valve 16: In addition, a valve 16 is also provided on the main pipe to control the flow and distribution of the entire system. This can be used for global system control to ensure that the fluid is distributed between the various crystallizers as required, while coordinating the operation of each crystallizer.

[0059] This embodiment provides a higher level of control and adjustment capabilities to accommodate different process conditions and requirements. By independently controlling the branch pipes of each crystallizer and the flow direction of the product, the crystallization process can be optimized to ensure the desired product quality and output. The valve 16 on the main pipe also allows for global fluid management throughout the system. This configuration is particularly suitable for complex crystallization processes that require fine adjustment.

[0060] In an optional embodiment, the A crystallizer 01 is provided with a second discharge branch pipe 18 for connecting to the B crystallizer 02.

[0061] In an optional embodiment, the second discharge pipe assembly 10 is provided with a third discharge branch pipe 19 for connecting the D crystallizer 04 and the F crystallizer 06 .

[0062] In an optional embodiment, a fourth discharge branch pipe 20 is provided on the D crystallization tube for connecting to the E crystallizer 05.

[0063] In an optional embodiment, the E crystallizer 05 is provided with a fifth discharge branch pipe 21 for connecting to the F crystallizer 06 .

[0064] In these optional embodiments, a second discharge branch pipe 18 is provided on the A crystallizer 01 for communicating with the B crystallizer 02. This means that the product of the A crystallizer 01 is guided to the B crystallizer 02 through the second discharge branch pipe 18, and can be further processed or reacted in the B crystallizer 02.

[0065] A third discharge branch pipe 19 is provided on the second discharge pipe assembly 10 for communicating with the E crystallizer 05 and the F crystallizer 06. A fourth discharge branch pipe 20 is provided on the D crystallizer 04 for communicating with the E crystallizer 05.

[0066] This structure further optimizes the flexibility and controllability of the system, allowing more complex fluid interactions between different crystallizers to meet specific process requirements. The connection between each crystallizer is set up with different discharge pipes, so that the product can selectively enter different crystallizers, thereby realizing a more complex crystallization process or processing flow.

[0067] The solution provided by this application has the following advantages:

[0068] The device includes multiple crystallizers (A, B, C, D, E, F crystallizers), which means that multiple batches of materials can be processed simultaneously, improving production efficiency and output.

[0069] Through the reasonable design of the branch pipes and main pipes of the crystallizer, the flow of materials can be better distributed and controlled, ensuring the uniformity and stability of the crystallization process.

[0070] The first and second discharge pipe assemblies are connected to the centrifuge, which helps to effectively separate the crystallized products and can control the destination of different crystallizer products to improve product quality and production efficiency.

[0071] Crystallizers B, C, D, E, and F can be run in parallel, which helps to reduce production time and improve production continuity.

[0072] Each crystallizer can be operated independently, making it easier to manage and maintain. If one crystallizer needs repair or fails, the other crystallizers can still continue production.

[0073] The device can reduce the energy consumption of materials because it can more effectively control the crystallization process and reduce material waste.

[0074] The multi-crystallizer system and automated control can reduce the workload of operators and reduce the need for manual operation, thereby reducing labor intensity.
