Description

Technical Field

[0002] As a key material in lithium-ion battery manufacturing, the specific surface area of ​​ternary precursors significantly impacts the performance of battery cells. High specific surface area precursors require sufficient oxygen in the reactor process to fully oxidize the slurry. However, in actual production, the oxidizing gas is mostly provided by compressed air from air compressors, and compressed gas is needed in many places throughout the workshop, such as pneumatic valves and filter presses. This leads to unstable flow rates of compressed gas entering the reactor, resulting in insufficient oxygen concentration within the reactor. Consequently, the oxidation degree of the ternary precursor is uneven, affecting the quality of the finished ternary precursor product. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a production gas supply mechanism and production device based on ternary precursors that can fully oxidize ternary precursors to improve the quality of ternary precursor finished products.

[0035] Please see Figure 1 To better understand the production gas supply mechanism 10 based on ternary precursors disclosed herein, the following further explanation of the production gas supply mechanism 10 based on ternary precursors is provided:

[0036] One embodiment of the ternary precursor-based production air supply mechanism 10 includes a compressed air supply assembly 100, an oxygen concentration detector 300, and an oxygen compensation assembly 400. The compressed air supply assembly 100 includes an air compressor 110 and a main gas supply pipe 120. The outlet of the air compressor 110 is connected to one end of the main gas supply pipe 120, and the other end of the main gas supply pipe 120 is connected to the inlet of the reactor 200. The oxygen concentration detector 300 is mounted on the main gas supply pipe 120. The outlet of the oxygen compensation assembly 400 is connected to the main gas supply pipe 120.

[0037] In this embodiment, by connecting the outlet of the air compressor 110 to one end of the gas delivery pipe 120 and the other end of the gas delivery pipe 120 to the inlet of the reactor 200, the compressed air input by the air compressor 110 can be delivered to the reactor 200 through the gas delivery pipe 120. At the same time, the oxygen concentration of the gas delivery pipe 120 is detected by the oxygen concentration detector 300. When the oxygen concentration detector 300 shows that the oxygen concentration of the gas delivery pipe 120 is lower than the production oxygen concentration value of the ternary precursor, oxygen is delivered to the delivery pipe through the oxygen compensation component 400 so that the oxygen concentration of the compressed air in the gas delivery pipe 120 meets the production oxygen concentration requirements of the ternary precursor. This ensures that the slurry in the reactor 200 can be fully oxidized, making the oxidation degree of the ternary precursor uniform, thereby improving the quality of the ternary precursor product.

[0038] like Figure 1 As shown, in one embodiment, the production gas supply mechanism 10 further includes a buffer tank 500, which is disposed on the gas supply main pipe 120 and is connected to the oxygen compensation component 400. It is understood that compressed air is delivered to the buffer tank 500 via the air compressor 110, and the oxygen compensation component 400 also delivers oxygen to the buffer tank 500, allowing the compensated oxygen and compressed air to mix thoroughly in the buffer tank 500 to form a mixed gas. The oxygen concentration in the mixed gas matches the oxygen production concentration of the ternary precursor in the reactor 200. The mixed gas is then delivered from the buffer tank 500 to the reactor 200, ensuring that the slurry in the reactor 200 is fully oxidized, resulting in uniform oxidation of the ternary precursor and improving the quality of the finished ternary precursor product.

[0039] like Figure 1As shown, in one embodiment, the main gas supply pipe 120 includes a first gas supply pipe 1210 and a second gas supply pipe 1220. One end of the first gas supply pipe 1210 is connected to the outlet of the air compressor 110, and the other end is connected to the first inlet of the buffer tank 500. One end of the second gas supply pipe 1220 is connected to the outlet of the buffer tank 500, and the other end is connected to the inlet of the reactor 200. An oxygen concentration detector 300 is installed on the second gas supply pipe 1220, and the second inlet of the buffer tank 500 is connected to the outlet of the oxygen compensation component 400. It can be understood that the compressed air from the air compressor 110 first passes through the first gas supply pipe 1210 to the buffer tank 500. Because the second gas supply pipe 1220 is connected to the buffer tank 500 and the oxygen concentration detector 300 is installed on the second gas supply pipe 1220, the oxygen concentration of the compressed air in the buffer tank 500 can be detected. When the oxygen concentration is insufficient, oxygen is delivered to the buffer tank 500 through the oxygen compensation component 400 and mixed with compressed air to make the oxygen concentration in the mixed gas match the oxygen production concentration of the ternary precursor in the reactor 200. The mixed gas in the buffer tank 500 is delivered to the reactor 200 through the second gas delivery pipe 1220 to ensure that the slurry in the reactor 200 can be fully oxidized, so that the oxidation degree of the ternary precursor is uniform and the quality of the ternary precursor product is improved.

[0040] like Figure 1 As shown, in one embodiment, the oxygen compensation component 400 includes an oxygen tank 410 and an oxygen delivery pipe 420. The outlet of the oxygen tank 410 is connected to one end of the oxygen delivery pipe 420, and the other end of the oxygen delivery pipe 420 is connected to the second inlet of the buffer tank 500. It can be understood that the oxygen tank 410 serves as an oxygen source, allowing oxygen to be delivered to the buffer tank 500 through the oxygen delivery pipe 420 to compensate for oxygen deficiency, ensuring that the slurry in the reactor 200 can be fully oxidized, resulting in a uniform oxidation degree of the ternary precursor and improving the quality of the final ternary precursor product.

[0041] like Figure 1As shown, in one embodiment, the compressed air supply assembly 100 further includes a first manual regulating valve 130 and a second manual regulating valve 140. The first manual regulating valve 130 is disposed on the first gas supply pipeline 1210, and the second manual regulating valve 140 is disposed on the second gas supply pipeline 1220. The oxygen compensation assembly 400 includes a third manual regulating valve 430, which is disposed on the oxygen supply pipeline 420. It can be understood that the first manual regulating valve 130 is a switch controlling the connection between the air compressor 110 and the first gas supply pipeline 1210, i.e., a switch controlling the input of compressed air; the second manual regulating valve 140 is a switch controlling the connection between the buffer tank 500, the second gas supply pipeline 1220, and the reactor 200, i.e., a switch controlling the input of mixed gas; and the third manual regulating valve is a switch controlling the connection between the oxygen tank 410 and the oxygen supply pipeline 420, i.e., a switch controlling the input of oxygen.

[0042] like Figure 1 As shown, in one embodiment, the compressed air supply assembly 100 further includes a first pneumatic regulating valve 150 and a second pneumatic regulating valve 160. The first pneumatic regulating valve 150 is disposed on the first air supply pipeline 1210, and the second pneumatic regulating valve 160 is disposed on the second air supply pipeline 1220. The oxygen compensation assembly 400 further includes a third pneumatic regulating valve 440, which is disposed on the oxygen supply pipeline 420. Understandably, the flow rate of compressed air in the first gas delivery pipeline 1210 is regulated by controlling the first pneumatic regulating valve 150. However, the air compressor 110 not only supplies air to the reactor 200 but also to other equipment in the ternary precursor production line. This can lead to insufficient compressed air flow in the first gas delivery pipeline 1210. In this case, the oxygen detector will report that the oxygen concentration in the mixed gas is insufficient. Then, the oxygen flow rate in the oxygen delivery pipeline 420 is regulated by controlling the third pneumatic regulating valve 440 to compensate for the insufficient oxygen flow in the compressed air. The flow rate of the mixed gas is then controlled by controlling the second pneumatic regulating valve 160 to ensure that the oxygen flow rate of the mixed gas in the second gas delivery pipeline 1220 meets the oxygen flow rate requirements in the reactor 200. This ensures that the slurry in the reactor 200 can be fully oxidized, resulting in uniform oxidation of the ternary precursor and improving the quality of the finished ternary precursor product.

[0043] like Figure 1As shown, in one embodiment, the compressed air supply assembly 100 further includes a first pressure transmitter 170 and a second pressure transmitter 180. The first pressure transmitter 170 is disposed on the first gas supply pipeline 1210, and the second pressure transmitter 180 is disposed on the second gas supply pipeline 1220. The oxygen compensation assembly 400 further includes a third pressure transmitter 450, which is disposed on the oxygen supply pipeline 420. It is understood that the first pressure transmitter 170 monitors the pressure value of the first gas supply pipeline 1210 in real time, the second pressure transmitter 180 monitors the pressure value of the second gas supply pipeline 1220 in real time, and the third pressure transmitter 450 monitors the pressure value of the oxygen supply pipeline 420 in real time, thus preventing safety accidents caused by excessive pressure in the pipelines and ensuring the safety of the production gas supply mechanism 10 during gas supply.

[0044] like Figure 1 As shown, in one embodiment, the compressed air supply assembly 100 further includes a first flow transmitter 190 and a second flow transmitter 1100, the first flow transmitter 190 being disposed on the first air supply pipe 1210 and the second flow transmitter 1100 being disposed on the second air supply pipe 1220. The oxygen compensation assembly 400 further includes a third flow transmitter 460, the third flow transmitter 460 being disposed on the oxygen supply pipe 420. Understandably, the compressed air flow rate of the first gas delivery pipeline 1210 is monitored in real time by the first flow transmitter 190, the mixed gas flow rate of the second gas delivery pipeline 1220 is monitored in real time by the second flow transmitter 1100, and the gas flow rate of the oxygen delivery pipeline 420 is monitored in real time by the third flow transmitter 460. The oxygen compensation mechanism is as follows: the oxygen concentration detector 300 can detect the oxygen concentration of the mixed gas in the second gas delivery pipeline 1220 in real time. The actual oxygen flow rate flowing into the reactor 200 can be calculated by the mixed gas flow rate and the oxygen concentration of the mixed gas. When the actual oxygen flow rate is less than the oxygen flow rate required for the production of the reactor 200, the oxygen flow rate of the oxygen delivery pipeline 420 is increased by controlling the third pneumatic regulating valve 440 to increase the oxygen flow rate in the mixed gas, so that the oxygen flow rate of the mixed gas in the second gas delivery pipeline 1220 meets the oxygen flow rate required for the production of the reactor 200. This ensures that the slurry in the reactor 200 can be fully oxidized, so that the oxidation degree of the ternary precursor is uniform and the quality of the ternary precursor product is improved.

[0045] like Figure 1As shown, in one embodiment, the production gas supply mechanism 10 includes a control component, which is communicatively connected to a first pneumatic regulating valve 150, a second pneumatic regulating valve 160, a third pneumatic regulating valve 440, a first pressure transmitter 170, a second pressure transmitter 180, a third pressure transmitter 450, a first flow transmitter 190, a second flow transmitter 1100, and a third flow transmitter 460. It is understandable that by establishing a communication connection between the first pneumatic regulating valve 150, the second pneumatic regulating valve 160, the third pneumatic regulating valve 440, the first pressure transmitter 170, the second pressure transmitter 180, the third pressure transmitter 450, the first flow transmitter 190, the second flow transmitter 1100, and the third flow transmitter 460 through the control component, the valve openings of the first pneumatic regulating valve 150, the second pneumatic regulating valve 160, and the third pneumatic regulating valve 440 are eliminated without manual adjustment. This achieves intelligent oxygen compensation, improves production efficiency, reduces the safety hazard of human-caused fires, and enhances the safety of the production gas supply mechanism 10. In this embodiment, the control component is a control panel.

[0046] It should be noted that this disclosure only protects the communication connection relationship between the control component and its components. The control method of the control component belongs to the prior art and is not within the scope of protection of this disclosure.

[0047] This disclosure also provides a production apparatus based on ternary precursors, including the production gas supply mechanism based on ternary precursors described in any of the above embodiments.

[0048] In this embodiment, by adopting the production gas supply mechanism based on ternary precursors disclosed herein, it is possible to ensure that the slurry in the reactor can be fully oxidized, so that the oxidation degree of the ternary precursors is uniform, thereby improving the quality of the ternary precursor finished product. At the same time, it is possible to realize the intelligent oxygen compensation mechanism, thereby improving production efficiency and reducing the safety hazards of human-caused fires, and improving the safety of the production gas supply mechanism 10.

[0049] Since different ternary precursors require different oxygen flow rates, the following examples are provided. However, it should be noted that the following examples do not exhaust all possible situations, and the materials used in the following examples are commercially available unless otherwise specified.

[0050] Example 1

[0051] This ternary precursor requires an oxygen flow rate of 12 L / min into the reactor 200, with the oxygen content in the compressed air being 20.95%.

[0052] Open the first manual regulating valve 130, the second manual regulating valve 140, and the third manual regulating valve 430 to drive the air compressor 110 and oxygen tank 410 to output. The oxygen concentration detector 300 displays a value of 23.12%, the first flow transmitter 190 displays a value of 30 L / min, and the second flow transmitter 1100 displays a value of 40 L / min. By multiplying the value displayed by the second flow transmitter 1100 and the value displayed by the oxygen concentration detector 300, the actual oxygen flow rate of the mixed gas is obtained. After keeping two decimal places, it is 9.25 L / min, which is determined to be insufficient oxygen. Increase the outlet flow rate of the oxygen tank 410, that is, adjust the valve opening of the third pneumatic switch valve so that the value displayed by the third flow transmitter 460 is 12-30*20.95%, which is 5.72 L / min after keeping two decimal places.

[0053] Example 2

[0054] This ternary precursor requires an oxygen flow rate of 18 L / min into the reactor 200, with the oxygen content in the compressed air being 20.95%.

[0055] Open the first manual regulating valve 130, the second manual regulating valve 140, and the third manual regulating valve 430 to drive the air compressor 110 and oxygen tank 410 to output. The oxygen concentration detector 300 displays a value of 25.14%, the first flow transmitter 190 displays a value of 23 L / min, and the second flow transmitter 1100 displays a value of 48 L / min. By multiplying the value displayed by the second flow transmitter 1100 and the value displayed by the oxygen concentration detector 300, the actual oxygen flow rate of the mixed gas is obtained. After keeping two decimal places, it is 12.07 L / min, which is determined to be insufficient oxygen. Increase the outlet flow rate of the oxygen tank 410, that is, adjust the valve opening of the third pneumatic switch valve so that the value displayed by the third flow transmitter 460 is 18 - 23 * 20.95%, which is 13.18 L / min after keeping two decimal places.

[0056] Example 3

[0057] This ternary precursor requires an oxygen flow rate of 13 L / min into the reactor 200, with the oxygen content in the compressed air being 20.95%.

[0058] Open the first manual regulating valve 130, the second manual regulating valve 140, and the third manual regulating valve 430 to drive the air compressor 110 to output. The oxygen concentration detector 300 displays a value of 20.91%, the first flow transmitter 190 displays a value of 70 L / min, and the second flow transmitter 1100 displays a value of 70 L / min. By multiplying the value displayed by the second flow transmitter 1100 and the value displayed by the oxygen concentration detector 300, the actual oxygen flow rate of the mixed gas is obtained. The value is rounded to two decimal places, which is 14.63 L / min. This indicates that there is an excess of oxygen. Close the third pneumatic switch valve and reduce the output flow rate of the air compressor 110, i.e., adjust the valve opening of the first pneumatic switch valve so that the value displayed by the first flow transmitter 190 is 13 / 20.95%, which is rounded to two decimal places, which is 62.05 L / min.

[0059] Compared with the prior art, this disclosure has at least the following advantages:

[0060] By connecting the outlet of the air compressor to one end of the gas delivery pipe and the other end of the gas delivery pipe to the inlet of the reactor, the compressed air input from the air compressor can be delivered to the reactor through the gas delivery pipe. At the same time, the oxygen concentration in the gas delivery pipe is detected by an oxygen concentration detector. When the oxygen concentration detector shows that the oxygen concentration in the gas delivery pipe is lower than the production oxygen concentration value of the ternary precursor, oxygen is supplied to the delivery pipe through the oxygen compensation component to make the oxygen concentration of the compressed air in the gas delivery pipe meet the production oxygen concentration requirements of the ternary precursor. This ensures that the slurry in the reactor can be fully oxidized, making the oxidation degree of the ternary precursor uniform, thereby improving the quality of the ternary precursor product.

[0061] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
