[0036] The present application provides a reactor 1, please refer to Figure 1 The reactor 1 is used for preparing battery medium, including but not limited to phosphoric acid battery medium and the like.

[0037] In the process of preparing the material of the phosphoric acid battery, it may react with the metal material in the reaction environment. This will reduce the purity and electrochemical performance of the material, and even may cause safety problems. In the present embodiment, please continue to refer to Figure 1, the reactor 1 can include a concrete main body 100 and a corrosion-resistant layer 200, and the concrete main body 100 can be made of concrete.

[0038] The concrete main body 100 can be configured as a mixed structure. Further, the concrete main body 100 can include a concrete layer and a fiber structure, the concrete layer being a structure made of concrete material, and the fiber structure being arranged in the concrete layer. The fiber structure can be carbon fiber, etc., without limitation. The fiber structure in the concrete layer can enhance the structural strength or crack resistance. The limiting structure can improve the overall durability of the reactor 1 and prevent cracking caused by temperature changes. Moreover, compared with ordinary reinforced concrete structure, the fiber structure used in the present application can avoid the use of metal materials, which can avoid the reaction between the reaction solution and the metal materials, and can also avoid the mutual influence of the electromagnetic induction of the metal materials on the heating layer, thereby improving the use safety of the reactor 1.

[0039] There can be acidic substances in the reaction solution, which can corrode the concrete main body 100 and reduce the service life of the reactor 1. In the present embodiment, please refer to Figure 1 , the corrosion-resistant layer 200 is arranged on the cavity wall of the reaction cavity 110. Exemplarily, the corrosion-resistant layer 200 can be a thin layer with a thickness of 1-10 cm. The corrosion-resistant layer 200 can be a polymer layer (such as a polytetrafluoroethylene layer, etc.) or a ceramic layer, etc., which is not limited in the present embodiment. Moreover, the arrangement mode of the corrosion-resistant layer 200 includes but is not limited to spraying, sintering or smearing, etc. Exemplarily, the corrosion-resistant layer 200 can be made of ceramic, and the preparer can directly spray the ceramic material on the cavity wall of the reaction cavity 110 to form the corrosion-resistant layer 200 by high-temperature sintering or the like. The concrete main body 100 in the present embodiment provides structural support, and the corrosion-resistant layer 200 prevents corrosion of the reaction solution to ensure the service life and safety of the equipment.

In the embodiments of the present application, please refer to Figure 2 and Figure 3The reactor 1 can further include a heating layer 130 arranged between the inner wall of the concrete main body 100 and the corrosion-resistant layer 200, and the heating layer 130 can inductively heat the reaction solution. The heating layer 130 can adopt electromagnetic induction technology, and the heating layer 130 can transmit electromagnetic waves into the reaction cavity 110, so that the reaction solution in the reaction cavity 110 can be quickly heated, and the electromagnetic induction mode can accurately control the temperature in the reaction cavity 110 to avoid hot spots. In addition, because the inductive heating directly acts on the reaction solution, it can reduce heat loss.

[0041] In other cases, the heating layer 130 can adopt resistance heating and the like, that is, the heating layer 130 can directly generate heat, and the heat can be transmitted into the reaction cavity 110 to achieve heating operation, which will not be described in detail.

[0042] In a more specific embodiment, as shown in Figure 2 The reaction cavity 110 is provided with at least two reaction areas 120, and the number of reaction areas 120 can be 2, 3, or even more, without limitation. Please refer to Figure 4 The heating layer 130 includes at least two heating modules 131, and the number of heating modules 131 can be 2, 3, or even more, without limitation. At least one heating module 131 is arranged on the cavity wall of each reaction area 120, and the heating module 131 is used to heat the corresponding reaction area 120. This arrangement can enable different reaction areas 120 in the reaction cavity 110 to be independently temperature-controlled to adapt to the needs of different reaction stages. For example, one area needs a relatively higher temperature, and another area needs a relatively lower temperature, while different reaction steps are carried out at the same time to improve efficiency. The heating module 131 is independently controlled, flexibly adjusted, optimizes the reaction path, and improves the quality of the battery medium.

[0043] In other embodiments, the reactor 1 can be provided with a heat circulation mechanism (not shown in the figure), and the inner wall of the concrete main body 100 is provided with a circulation pipeline, and the heat circulation mechanism is in circulation communication with the circulation pipeline. The heat circulation mechanism is used to heat the heat conduction medium, which can be heat-conducting oil, water, etc., and transmit it into the circulation pipeline. The heat circulation mechanism heats the heat conduction medium through the circulation pipeline and transmits it into the reaction cavity 110. The arrangement of the heat circulation mechanism and the circulation pipeline can form uniform temperature distribution, avoid local overheating, and improve heating efficiency, so that the reaction conditions of the reaction solution are more stable.

[0044] In addition, the application can be provided with a refrigeration device, which can be connected to the pipeline in the cavity wall, and can deliver refrigeration medium into the pipeline to refrigerate the reaction solution inside the reaction cavity 110.

[0045] In the embodiments of the application, please refer to Figure 3 The reactor 1 can also be provided with a heat preservation and insulation layer 140, which can be a vacuum ceramic fiber composite layer, a microporous calcium silicate board, a multi-layer reflective insulation board, etc., and is not limited. The heat preservation and insulation layer 140 is arranged on the surface of the heating layer 130 away from the corrosion-resistant layer 200. The heat preservation and insulation layer 140 can reduce heat loss in the reaction cavity 110, maintain stable temperature of the reaction cavity 110, reduce energy consumption, avoid heat conduction to the concrete body 100 or the outside, improve the working environment safety and the service life of the concrete body 100.

[0046] In another embodiment, please refer to Figure 5 A vacuum gap 170 is arranged between the concrete body 100 and the corrosion-resistant layer 200, which has a vacuum atmosphere and can prevent heat conduction. The vacuum gap 170 can insulate the heat conducted by the corrosion-resistant layer 200. Further, the vacuum gap 170 can be arranged between the concrete body 100 and the heating layer 130, which can reduce the heat conducted by the heating layer 130, improve energy efficiency, and possibly reduce the impact on the external structure.

[0047] In addition, in some other cases, please refer to Figure 6 The reactor 1 can simultaneously use the vacuum gap 170 and the heat preservation and insulation layer 140, which improves the heat insulation effect, and details are not described here.

[0048] In some other embodiments, the reactor 1 can be provided with a heat cycle mechanism and a heating layer 130 at the same time, which can realize uniform heating and partition heating at the same time, to improve the heating effect of the reactor 1, and details are not described here.

[0049] In the embodiments of the application, please refer to Figure 4The reaction cavity 110 is provided with a sensor 150, which can be an infrared temperature sensor 150 or the like. The sensor 150 is used to obtain the temperature of the reaction area 120. The reactor 1 comprises a control member 113 electrically connected to the sensor 150 and the plurality of heating modules 131. The control member 113 comprises a processor 1131 capable of processing or transmitting signals and a memory 1132 capable of storing information. The sensor 150 monitors the temperature of the reaction area 120, and the control member 113 adjusts the heating modules 131 according to the temperature threshold. In a more specific embodiment, when the temperature of the reaction area 120 is greater than the temperature threshold, the control member 113 is used to turn off at least one heating module 131 corresponding to the reaction area 120, and when the temperature of the reaction area 120 is less than the temperature threshold, the control member 113 is used to turn on at least one heating module 131 corresponding to the reaction area 120. Wherein, at least one refers to one or more, such as 1, 2, … or even more, without limitation; the temperature threshold can be pre-stored in the memory 1132 or manually input into the control member 113 by the operator, without limitation.

[0050] The control member 113 can realize automatic control in the reactor 1, such as accurate maintenance of reaction conditions in a specific process, prevention of overheating or overcooling, improvement of safety and reaction rate. In addition, the control member 113 can quickly transmit temperature information and the like to an external device, so that the operator can obtain the temperature information, which realizes real-time feedback and automatic dynamic adjustment.

[0051] It can be understood that the control member 113 is electrically connected to the refrigeration device and the thermal cycle mechanism. When the heating modules 131 of the reaction area 120 have all been turned off, and the temperature of the reaction area 120 is still greater than the temperature threshold, the control member 113 can turn on the refrigeration device to reduce the temperature of the reaction area 120. When the heating modules 131 of the reaction area 120 have all been turned on, and the temperature of the reaction area 120 is still less than the temperature threshold, the control member 113 can turn on the thermal cycle mechanism to increase the temperature of the reaction area 120.

[0052] In other embodiments, please continue to refer to Figure 4 The concrete body 100 is provided with a pressure relief port, and the pressure relief port is provided with a pressure relief valve 112. The pressure relief valve 112 can release pressure when the pressure is too high to ensure safety. Further, the reaction cavity 110 is also provided with a pressure sensor which can monitor the pressure change in the reaction cavity 110. The control member 113 is electrically connected to the pressure sensor and the pressure relief valve 112, which can realize early warning and feedback. In addition, according to the signal of the pressure sensor or the control signal of the operator, the control member 113 can turn on the pressure relief valve 112 to change the internal pressure and improve the safety of the reactor 1.

[0053] In the embodiments of the present application, please refer to Figure 1 , the reactor 1 further comprises a bubble stirring mechanism 160, which extends into the reaction solution and is capable of injecting bubbles into the reaction solution. The bubble stirring mechanism 160 is capable of generating bubbles, which accelerate the mixing reaction of substances in the reactor 1 and enhance the stirring effect.

[0054] In a more specific embodiment, please continue to refer to Figure 1 , the bubble stirring mechanism 160 comprises a bubble generator (not shown in the figure) capable of generating bubbles and a plurality of tubes 162. The bubble generator is connected to the plurality of tubes 162, and the bubbles can be transported into the plurality of tubes 162. The plurality of tubes 162 are arranged at intervals, which can increase the application range of the bubble stirring mechanism 160, eliminate dead angles, and improve the stirring effect of the reactor 1. The plurality of tubes 162 are connected to the top of the concrete body 100 and extend obliquely towards the bottom of the concrete body 100. Among them, oblique extension refers to the extension of the tube 162 towards the bottom of the concrete body 100 and the oblique arrangement relative to the bottom of the concrete body 100. The arrangement of the tube 162 can transport the bubbles to the bottom side of the concrete body 100, promote the uniform stirring of the bottom of the reaction chamber 110, and improve the stirring effect. Moreover, the tube 162 can be arranged obliquely, which can ensure that the bubbles can easily flow out of the tube 162, avoid the accumulation of bubbles at the end of the tube 162, and improve the stirring effect.

[0055] More specifically, please continue to refer to Figure 1 , the plurality of tubes 162 each comprise a first end 1621 and a second end 1622 away from each other, and the first end 1621 is rotatably connected to the top of the concrete body 100, in other words, the first end 1621 can be hinged to the top of the concrete body 100. The bubble stirring mechanism 160 further comprises a driving member, which is also electrically connected to the control member 113 to accept its control. The driving member can be a hydraulic drive or a pneumatic drive, etc., and is not limited. The driving member is drivingly connected to the tube 162, and is used to drive the tube 162 to control the relative position of the second end 1622 in the reaction chamber 110. The driving member can control the tube 162 to rotate or swing to a specified position, so as to change the injection position and direction of the bubbles, so as to adapt to different positions of the reaction chamber 110, i.e. different depth regions of the reaction chamber 110. This can expand the coverage of the bubbles, avoid dead angles, improve the stirring efficiency, or adjust the stirring intensity according to different reaction stages, such as enhancing the mixing uniformity, promoting heat transfer, or adapting to different reaction requirements. In addition, the driving member can drive the tube 162 to change the inclination angle of the tube 162 to adapt to different effects.

[0056] In the embodiments of the present application, please continue to refer toFigure 1 The reactor 1 further comprises a first pipeline 161, one end of the first pipeline 161 extends to the bottom of the reaction cavity 110, and the other end is connected to the bubble generator of the bubble stirring mechanism 160. The first pipeline 161 can inject bubbles from the bottom, and the bottom injection of bubbles can more effectively stir the sediment or form an up-down circulating flow to enhance the overall mixing.

[0057] Preferably, the bubble generator is provided with a bubble disperser, which can divide the bubbles into small bubbles. The small bubbles promote the mixing of the reaction solution, and the relatively smaller and more dispersed bubbles are less likely to affect the stability of the reaction solution, thereby promoting more uniform reaction.

[0058] During the reaction process, the reaction medium in the reaction cavity 110 can be precipitated or crystallized, forming reaction slag, which can reduce the purity of the battery medium or affect the stability of the reaction medium. In the embodiment of the present application, please continue to refer to Figure 7 The reactor 1 further comprises a solid-liquid separation mechanism 300, and the concrete body 100 further has a treatment cavity 111, the solid-liquid separation mechanism 300 is arranged in the treatment cavity 111, and the solid-liquid separation mechanism 300 and the reaction cavity 110 are in communication with each other. The reaction solution, reaction slag and the like in the reaction cavity 110 can flow into the solid-liquid separation mechanism 300. Illustratively, the solid-liquid separation mechanism 300 comprises a shell 310, a driving motor 320 and a spiral rotating rod 330. The shell 310 is arranged in the treatment cavity 111, and the shell 310 is provided with a feeding port 311 and a discharging port 312, both of which are connected to the reaction cavity 110. The reaction solution and the reaction slag and the like mixed medium can enter the shell 310 through the feeding port 311. When the driving motor 320 is powered, the driving motor 320 is drivingly connected to the spiral rotating rod 330, the spiral rotating rod 330 is arranged in the shell 310 and can extrude the mixed medium in the shell 310 to separate the reaction slag and the reaction solution, the reaction slag can be discharged and collected, and the reaction solution can be discharged back to the reaction cavity 110 through the discharging port 312. The reaction slag is discharged to the reactor 1 to avoid affecting the reaction rate and the substance, and the reaction solution can be discharged back to the reaction cavity 110 to reduce the waste of the reaction solution and improve the use efficiency.

[0059] Further, please continue to refer to Figure 7The number of reactors 1 is not limited, and is for example two, three or more. The plurality of reactors 1 are in communication with each other, and the solid-liquid separation mechanism 300 of one of the two adjacent reactors 1 is in communication with the reaction cavity 110 of the other reactor 1. For example, each reactor 1 can be responsible for a different processing stage, such as the first reactor 1 performing a reaction, and then the solid-liquid separation mechanism 300 separating the reaction residue and the reaction medium, and the reaction medium entering the next reactor 1 for further processing. Specifically, the discharge port 312 of the first reactor 1 can be in communication with the reaction cavity 110 of the second reactor 1, so as to realize the series connection of the plurality of reactors 1. In this way, the material transfer is smoother, the intermediate storage link is reduced, pollution or material loss is avoided, and the process can be automated, reducing manual intervention, and continuous processing can improve efficiency, as there is no need to stop for cleaning or material transfer.

[0060] The technical scheme adopted by the utility model can achieve the following beneficial effects: the concrete main body 100 can provide the reaction cavity 110, the reaction cavity 110 can accommodate the reaction solution, the reaction solution can react in the reaction cavity 110 to prepare the required battery medium, such as lithium iron phosphate battery medium, etc. The concrete main body 100 has low cost, fast forming and strong plasticity, which can solve the problem of high cost of non-metal materials. In addition, the inner wall of the concrete main body 100 is also provided with a corrosion-resistant layer 200, which effectively prevents the corrosion of the reaction solution on the concrete main body 100 and improves the service life of the concrete main body 100.
