Description

Technical Field

[0001] This application relates to the technical field of kilns, and more particularly to a voltage stabilizing device, kiln equipment, and control method. Background Technology

[0002] In the production process of lithium-ion cathode materials, sintering lithium-ion cathode materials in a kiln is one of the most important steps. During the sintering process, the kiln is equipped with an exhaust device to remove waste gas from the kiln in a timely manner, so as to ensure the sintering quality of the lithium-ion cathode materials.

[0003] However, seasonal / temperature changes in the external environment cause real-time changes in atmospheric pressure. If the atmospheric pressure increases, the exhaust system will be less effective at venting the furnace, affecting the sintering quality of the lithium-ion cathode material. If the atmospheric pressure decreases, the exhaust system will be more effective at venting the furnace, resulting in significant heat waste in the furnace, which may also affect the sintering quality of the lithium-ion cathode material.

[0038] Reference Figure 1 and Figure 2 This application discloses a pressure stabilizing device applied to the exhaust port of a kiln. The pressure stabilizing device includes a pressure stabilizing box 100 and an exhaust mechanism 400. The pressure stabilizing box 100 has a pressure stabilizing chamber 110, an air inlet 120 and an air outlet 130 that are connected to each other. The air inlet 120 is used to connect with the exhaust port to receive the exhaust gas discharged from the exhaust port. The exhaust mechanism 400 is disposed at the air outlet 130 to allow the gas in the pressure stabilizing chamber 110 to be discharged from the air outlet 130, so that the gas pressure in the pressure stabilizing chamber 110 is maintained within a set range.

[0039] Specifically, the pressure stabilizing device is installed at the exhaust port of the kiln, and the kiln is connected to the pressure stabilizing chamber 110 of the pressure stabilizing box 100 through the exhaust port. During operation, the kiln's exhaust device discharges the waste gas from the kiln through the exhaust port, and the discharged waste gas enters the pressure stabilizing chamber 110 of the pressure stabilizing box 100 through the inlet 120. Under the action of the exhaust mechanism 400, the waste gas in the pressure stabilizing chamber 110 is discharged from the outlet 130.

[0040] In conventional techniques, to solve the problems mentioned in the background technology, workers manually adjust the operating speed of the exhaust device. For example, when the ambient air pressure is high, workers increase the operating speed of the exhaust device to ensure that the exhaust gas in the kiln is discharged quickly, and when the ambient air pressure is low, workers decrease the operating speed of the exhaust device to ensure that the exhaust gas in the kiln is discharged excessively.

[0041] In this application, the pressure stabilizing device is installed at the kiln outlet 130. Operators maintain the air pressure in the pressure stabilizing chamber 110 within a set range using the exhaust mechanism 400. Thus, regardless of changes in the external ambient air pressure, the exhaust gas from the kiln is always discharged at a stable rate. The operating speed of the exhaust mechanism 400 can be manually controlled or automatically controlled by the control system.

[0042] In summary, conventional techniques control the kiln's exhaust speed by adjusting the exhaust device. However, with changes in the external environment, it's difficult for operators to maintain a stable exhaust rate. In this application, the exhaust efficiency is controlled by adjusting the pressure in the pressure stabilizing chamber 110. Furthermore, since the exhaust mechanism 400 can easily control the pressure in the pressure stabilizing chamber 110, this application ensures a more stable exhaust speed compared to conventional techniques, thereby guaranteeing the sintering quality of the material and reducing unnecessary heat waste.

[0043] Further verification was conducted by turning on / off the voltage regulator 100, using the same batch of lithium-ion cathode materials to eliminate input differences in key process quality characteristics. The impact of turning the voltage regulator 100 on / off on the free lithium in the solid-state sintering of the cathode material was compared. The specific data is shown below:

[0044] 1. Comparison of differences at different times of the same day:

[0045]

[0046] 2. Comparison of differences across different seasons:

[0047]

[0048] In summary, the improved voltage regulator 100 effectively controls the quality of cathode materials in different seasons and at different times of day and night, achieving the expected results.

[0049] In some embodiments, the pressure stabilizing device further includes a control module for controlling the operating speed of the exhaust mechanism 400. Specifically, the control module automatically controls the operating speed of the exhaust mechanism 400 to ensure that the pressure stabilizing chamber 110 remains within a set range. For example, if the ambient air pressure increases, the control module automatically increases the operating speed of the exhaust mechanism 400, allowing the exhaust gas in the pressure stabilizing chamber 110 to be discharged normally, thus ensuring that the air pressure in the pressure stabilizing chamber 110 remains within the set range; if the ambient air pressure decreases, the control module automatically decreases the operating speed of the exhaust mechanism 400, preventing the exhaust gas in the pressure stabilizing chamber 110 from dissipating too quickly, thus ensuring that the air pressure in the pressure stabilizing chamber 110 remains within the set range. The set range is between -16 Pa and -24 Pa.

[0050] In one possible embodiment, the pressure stabilizing device further includes a first air pressure detection module, which is disposed on the top of the pressure stabilizing chamber 100 and used to detect the air pressure in the pressure chamber. For example, the first air pressure detection module includes a first air pressure gauge 200, which is disposed on the top of the pressure stabilizing chamber 100, and the probe of the first air pressure gauge 200 extends into the pressure stabilizing chamber 110. The first air pressure detection module obtains the air pressure value in the pressure stabilizing chamber 110 through the first air pressure gauge 200. The control module is electrically connected to the first air pressure detection module, and the first air pressure detection module feeds back the acquired signal to the control module. The control module adjusts the operating speed of the exhaust mechanism 400 based on the air pressure value in the pressure stabilizing chamber 110.

[0051] In practice, when the ambient air pressure increases, the first air pressure detection module detects that the air pressure in the pressure stabilizing chamber 110 is too high. The control module then increases the operating speed of the exhaust mechanism 400, allowing the exhaust gas in the pressure stabilizing chamber 110 to be discharged to the external environment in a timely manner. This ensures that the air pressure in the pressure stabilizing chamber 110 is around -20 Pa, thereby ensuring that the exhaust gas in the kiln can be discharged into the pressure stabilizing chamber 110 at a stable rate. Conversely, when the ambient air pressure decreases, the first air pressure detection module detects that the air pressure in the pressure stabilizing chamber 110 is too low. The control module then decreases the operating speed of the exhaust mechanism 400, slowing down the discharge of the exhaust gas from the pressure stabilizing chamber 110 to the external environment. This again ensures that the air pressure in the pressure stabilizing chamber 110 is around -20 Pa, thereby ensuring that the exhaust gas in the kiln can be discharged into the pressure stabilizing chamber 110 at a stable rate.

[0052] Furthermore, the pressure stabilizing device also includes an alarm module, which is electrically connected to the control module. The control module can control the alarm module to emit an alarm sound to alert the kiln equipment to malfunctions based on the air pressure value in the pressure stabilizing chamber 110. Specifically, when the ambient air pressure changes, causing the air pressure value detected by the first pressure gauge 200 to increase or decrease, if the air pressure increases to the upper limit, it indicates that the pressure stabilizing device is malfunctioning, resulting in the waste gas in the pressure stabilizing chamber 110 not being discharged in time. In this case, the alarm module will emit an alarm sound to remind the staff that the pressure stabilizing device needs maintenance. If the air pressure decreases to the lower limit, it indicates that the pressure stabilizing device is malfunctioning, resulting in the waste gas in the pressure stabilizing chamber 110 being discharged rapidly. In this case, the alarm module will emit an alarm sound to remind the staff that the pressure stabilizing device needs maintenance.

[0053] In another possible embodiment, the pressure stabilizing device further includes a second pressure detection module, which is used to acquire a first pressure difference between the pressure stabilizing chamber 110 and the external environment. For example, the second pressure detection module includes a first pressure gauge 200 and a third pressure gauge. The first pressure gauge 200 is disposed on the top of the pressure stabilizing box 100, and its probe extends into the pressure stabilizing chamber 110. The first pressure gauge 200 is used to detect the pressure value of the exhaust gas in the pressure stabilizing chamber 110. The location of the third pressure gauge is not limited, and it is used to detect the pressure of the external environment. Based on the measured values ​​of the first and third pressure gauges, the aforementioned first pressure difference is acquired. A control module is electrically connected to the second pressure detection module. The control module acquires the value of the first pressure difference and controls the operating speed of the exhaust mechanism 400 based on the value of the first pressure difference.

[0054] In practical implementation, an increase in ambient air pressure causes a corresponding change in the first pressure difference. Based on this change, the control module increases the operating speed of the exhaust mechanism 400, ensuring that the exhaust gas in the pressure stabilizing chamber 110 is promptly discharged into the external environment. This maintains the pressure in the pressure stabilizing chamber 110 at approximately -20 Pa, thereby ensuring that the exhaust gas in the kiln is discharged into the pressure stabilizing chamber 110 at a stable rate. Alternatively, a decrease in ambient air pressure causes a corresponding change in the first pressure difference. Based on this change, the control module decreases the operating speed of the exhaust mechanism 400, slowing the discharge of exhaust gas from the pressure stabilizing chamber 110 into the external environment. This maintains the pressure in the pressure stabilizing chamber 110 at approximately -20 Pa, ensuring that the exhaust gas in the kiln is discharged into the pressure stabilizing chamber 110 at a stable rate.

[0055] Furthermore, the pressure stabilizing device also includes an alarm module, which is electrically connected to the control module. Based on the aforementioned first pressure difference, the control module can control the alarm module to emit an alarm sound to alert the kiln equipment to malfunctions. Specifically, when the ambient air pressure changes, the aforementioned first pressure difference increases or decreases. If the first pressure difference increases to its upper limit, it indicates a malfunction in the pressure stabilizing device, causing the exhaust gas in the pressure stabilizing chamber 110 to not be discharged in time. In this case, the alarm module will emit an alarm sound to remind the staff that the pressure stabilizing device needs maintenance. If the first pressure difference decreases to its lower limit, it indicates a malfunction in the pressure stabilizing device, causing the exhaust gas in the pressure stabilizing chamber 110 to be discharged rapidly. In this case, the alarm module will emit an alarm sound to remind the staff that the pressure stabilizing device needs maintenance.

[0056] In another possible embodiment, the pressure stabilizing device further includes a third pressure detection module, which is used to acquire a second pressure difference between the pressure stabilizing chamber 110 and the kiln environment. For example, the third pressure detection module includes a first pressure gauge 200 and a fourth pressure gauge. The first pressure gauge 200 is disposed on the top of the pressure stabilizing box 100, and its probe extends into the pressure stabilizing chamber 110. The first pressure gauge 200 is used to detect the temperature of the exhaust gas in the pressure stabilizing chamber 110. The fourth pressure gauge is disposed in the kiln and is used to detect the pressure difference with the kiln environment. Based on the measurements of the first and fourth pressure gauges, the aforementioned second pressure difference is acquired. A control module is electrically connected to the third pressure detection module. The control module acquires the value of the second pressure difference and controls the operating speed of the exhaust mechanism 400 based on the value of the second pressure difference.

[0057] In practical implementation, when the ambient air pressure increases, the exhaust effect of the exhaust mechanism 400 decreases, and the pressure in the pressure stabilizing chamber 110 increases, resulting in a corresponding change in the value of the second pressure difference. Based on the change in the second pressure difference, the control module increases the operating speed of the exhaust mechanism 400, ensuring that the waste gas in the pressure stabilizing chamber 110 can be discharged to the external environment in a timely manner, thereby maintaining the air pressure value of the pressure stabilizing chamber 110 at around -20 Pa, and thus ensuring that the waste gas in the kiln can be discharged into the pressure stabilizing chamber 110 at a stable rate. Conversely, when the ambient air pressure decreases, the exhaust effect of the exhaust mechanism 400 increases, and the pressure in the pressure stabilizing chamber 110 decreases, resulting in a corresponding change in the value of the second pressure difference. Based on the change in the first pressure difference, the control module decreases the operating speed of the exhaust mechanism 400, slowing down the discharge of waste gas from the pressure stabilizing chamber 110 to the external environment, thereby maintaining the air pressure value of the pressure stabilizing chamber 110 at around -20 Pa, and thus ensuring that the waste gas in the kiln can be discharged into the pressure stabilizing chamber 110 at a stable rate.

[0058] Furthermore, the pressure stabilizing device also includes an alarm module, which is electrically connected to the control module. Based on the aforementioned second pressure difference, the control module can control the alarm module to emit an alarm sound to alert the kiln equipment to malfunctions. Specifically, when the ambient air pressure changes, the second pressure difference increases or decreases. If the second pressure difference increases to its upper limit, it indicates a malfunction in the pressure stabilizing device, causing the exhaust gas in the pressure stabilizing chamber 110 to not be discharged in time. In this case, the alarm module will emit an alarm sound to remind the staff that the pressure stabilizing device needs maintenance. If the second pressure difference decreases to its lower limit, it indicates a malfunction in the pressure stabilizing device, causing the exhaust gas in the pressure stabilizing chamber 110 to be discharged rapidly. In this case, the alarm module will emit an alarm sound to remind the staff that the pressure stabilizing device needs maintenance.

[0059] In some embodiments, refer to Figure 1 and Figure 2The pressure stabilizing chamber 100 has an air inlet 120 on its left side wall and an air outlet 130 on its right side wall. A first pressure gauge 200 is mounted on the top of the pressure stabilizing chamber 100. The probe of the first pressure gauge 200 is located inside the pressure stabilizing chamber 110 and is offset from the line connecting the air inlet 120 and the air outlet 130, and is positioned away from both the air inlet 120 and the air outlet 130. This reduces the impact of vortices caused by gas backflow at certain locations on the accuracy of the test.

[0060] Furthermore, the projections of the air inlet 120 and the air outlet 130 onto the setting surface are staggered. The orientations of both the air inlet 120 and the air outlet 130 are perpendicular to the setting surface, meaning the setting surface is perpendicular to the left-right direction. This staggered arrangement of the air inlet 120 and the air outlet 130 reduces the rapid discharge of gas from the air inlet 120 through the air outlet 130, thus aiding the exhaust mechanism 400 in controlling the pressure in the pressure stabilizing box 100 and ensuring that the pressure in the pressure stabilizing box 100 remains within the set range.

[0061] In some embodiments, the voltage stabilizing device further includes a first temperature sensor 300, which is disposed on the top of the voltage stabilizing box 100 and is used to measure the temperature of the exhaust gas in the voltage stabilizing chamber 110.

[0062] In some embodiments, the voltage regulator 100 includes an inner shell, an insulation layer, and an outer shell (not shown in the figure). The inner shell defines the aforementioned voltage regulating chamber 110, the insulation layer wraps around the outside of the inner shell, and the outer shell is disposed outside the insulation layer. The inner shell may be made of stainless steel to ensure the durability of the voltage regulator 100; the insulation layer may be made of insulation cotton to reduce heat transfer to the outer shell, thereby preventing burns to personnel from the voltage regulator 100; the outer shell may be made of aluminum, serving as heat insulation and ensuring the corrosion resistance of the voltage regulator 100.

[0063] In some embodiments, the pressure stabilizing device further includes an inlet pipe 140 and an outlet pipe 150. One end of the inlet pipe 140 is connected to the kiln and communicates with the kiln's exhaust port, while the other end is connected to the pressure stabilizing box 100 and communicates with the inlet port 120. One end of the outlet pipe 150 is connected to the pressure stabilizing box 100 and communicates with the outlet port 130, while the other end is connected to the exhaust mechanism 400 and communicates with the exhaust gas inlet of the exhaust mechanism 400. The arrangement of the inlet pipe 140 and the outlet pipe 150 facilitates the mounting of the pressure stabilizing box 100 on one side of the kiln.

[0064] Furthermore, the pressure stabilizing device also includes a second temperature sensor 142 and a second pressure sensor 141, both of which are installed in the intake pipe 140. The second temperature sensor 142 is used to detect the temperature of the exhaust gas in the intake pipe 140, and the second pressure sensor 141 is used to detect the pressure of the exhaust gas in the intake pipe 140. The installation of the second temperature sensor 142 and the second pressure sensor 141 facilitates the monitoring of changes in exhaust gas pressure and temperature by personnel.

[0065] In some embodiments, the pressure stabilizing device further includes an air supply valve 500, which is disposed in the pressure stabilizing box 100 and used to adjust the air pressure in the pressure stabilizing chamber 110. In practical applications, when the pressure stabilizing device cannot automatically control the air pressure in the pressure stabilizing chamber 110 through the exhaust mechanism 400, the operator can temporarily adjust the air pressure in the pressure stabilizing chamber 110 through the air supply valve 500 to ensure the normal functioning of the pressure stabilizing device.

[0066] In some embodiments, the exhaust mechanism 400 includes a housing 420 and an exhaust assembly 410. The housing 420 defines a communicating exhaust gas inlet, an exhaust passage, and an exhaust gas outlet 421. One end of the exhaust pipe 150, away from the voltage regulator 100, is connected to the housing 420 and communicates with the exhaust gas inlet. The exhaust assembly 410 is disposed on the housing 420, allowing exhaust gas to enter the exhaust passage from the exhaust gas inlet and be discharged to the external environment from the exhaust gas outlet 421. The exhaust passage includes an outlet portion with the exhaust gas outlet 421. The axial direction of the outlet portion is inclined downwards at an angle between 20 and 30 degrees relative to the horizontal direction, thus allowing exhaust gas to be discharged downwards at an angle through the exhaust gas outlet 421. It is understood that using the aforementioned downward angle of 20 to 30 degrees for exhaust gas discharge reduces the impact of external environmental factors on the exhaust of the voltage regulator, ensuring smooth exhaust.

[0067] This application also discloses a kiln equipment, characterized in that it includes a kiln, an exhaust device and the aforementioned pressure stabilizing device, wherein: the kiln has an exhaust port for discharging waste gas; the exhaust device is disposed at the exhaust port for discharging waste gas from the kiln through the exhaust port; the pressure stabilizing box 100 is connected to the kiln, and the exhaust port is connected to the air inlet 120.

[0068] Specifically, by incorporating the aforementioned pressure stabilizing device, the kiln equipment controls the exhaust efficiency by regulating the air pressure in the pressure stabilizing chamber 110 during actual operation. Therefore, regardless of changes in the external ambient air pressure, the exhaust gas from the kiln is consistently discharged at a stable rate.

[0069] This application also discloses a control method applied to a voltage stabilizing device. The voltage stabilizing device includes a voltage stabilizing box 100 and an exhaust mechanism 400. The voltage stabilizing box 100 has a voltage stabilizing chamber 110, an air inlet 120, and an air outlet 130 connected in series. The air inlet 120 is used to connect to the exhaust port of a kiln to receive the exhaust gas discharged from the exhaust port. The exhaust mechanism 400 is disposed at the air outlet 130 to allow the gas in the voltage stabilizing chamber 110 to be discharged from the air outlet 130, wherein:

[0070] The control method includes controlling the working speed of the exhaust mechanism 400 based on one of the air pressure value in the pressure stabilizing chamber 110, the first pressure difference between the pressure stabilizing chamber 110 and the external environment, and the second pressure difference between the pressure stabilizing chamber 110 and the kiln internal environment, so as to ensure that the air pressure in the pressure stabilizing chamber 110 is within the set range.

[0071] Specifically, by controlling the pressure stabilizing device using the above method, the air pressure value of the pressure stabilizing chamber 110 is always maintained within the set range, thereby ensuring a relatively stable exhaust efficiency from the kiln. In this way, the pressure stabilizing device guarantees the sintering quality of the materials in the kiln and reduces unnecessary heat waste.

[0072] By controlling the air pressure in the pressure stabilizing chamber 110, the exhaust efficiency of the kiln can be controlled. Furthermore, because operators can easily control the air pressure in the pressure stabilizing chamber 110 within the set range using the exhaust mechanism 400, compared to conventional techniques, operators can ensure a more stable exhaust efficiency for the kiln, thus guaranteeing better sintering quality of the materials and avoiding unnecessary waste of heat.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
