Description

Technical Field

[0001] This application relates to the field of battery production technology, and in particular to a slurry pipeline blockage detection system and a battery production system. Background Technology

[0002] In the manufacturing process of battery electrodes, slurry needs to be pumped from the mixer to a transfer tank via a slurry pipeline, and then from the transfer tank to the coating head for the coating process. The slurry pipeline is equipped with a ball-pushing system, which uses air pressure to push a cleaning ball to clean the pipeline of residual slurry and prevent blockage. However, slurry can accumulate and form gel, which can clog the pipeline. This can cause the cleaning ball to get stuck in the pipeline during the pushing process, requiring disassembly and cleaning of the corresponding blocked pipeline.

[0003] Currently, manual inspection is used to clear pipe blockages. Workers use handheld inspection devices to locate the blockages, which is inefficient and poses safety hazards due to the high position of the slurry pipes.

[0004] It should be noted that the above statements are only used to provide background information related to this application and do not necessarily constitute prior art. Utility Model Content

[0007] The above embodiments utilize the principle of magnetic induction to detect the position of the pigging ball, which can reflect the position of the pigging ball in real time. It has high sensitivity, strong anti-interference ability, and can realize non-contact detection, improve reliability and reduce maintenance costs. It eliminates the need for manual detection, improves pipeline blockage detection efficiency and production safety.

[0008] In some embodiments, the magnetic induction switch includes a Hall switch. This enables the detection unit to be miniaturized and have a fast response, allowing for high-density arrangement and real-time response, thereby improving detection accuracy and system compactness.

[0009] In some embodiments, the indicator module includes at least one light-emitting device, and a plurality of light-emitting devices of the indicator module form a light-emitting strip, the light-emitting strip comprising multiple segments, and adjacent segments of the light-emitting strip being detachably connected.

[0010] In this embodiment, the light-emitting strip includes multiple segments. The detachable connection between adjacent light-emitting strip segments can improve the adaptability of the slurry pipeline blockage detection system, making it applicable to pipelines of different lengths / shapes.

[0013] In some embodiments, the magnetic induction switch includes a dual-pole detection switch, which is connected to two light-emitting devices, the two light-emitting devices being configured to detect different magnetic poles.

[0014] This embodiment is compatible with pigging balls of different magnetic properties. When the shape of the pipeline changes, the detected magnetic poles may also change. Therefore, this embodiment is also compatible with different pipeline scenarios, enhancing its applicability.

[0015] In some embodiments, the light-emitting device includes at least one of a monochromatic light-emitting device and a multicolor light-emitting device.

[0016] The above embodiments can utilize the monochromatic or multicolor light emission characteristics of light-emitting devices to characterize different state information, which helps staff to intuitively determine the position of the cleaning ball and thus determine whether the pipeline is blocked.

[0017] In some embodiments, the at least one detection unit is arranged at equal intervals; in each detection unit, the distance between the magnetic induction switch and the light-emitting device of the indicating module is less than a preset distance.

[0019] It enables a visual display of the indicator module's status information, improving human-computer interaction and helping staff quickly determine the current position of the pigging jack. It can also reduce interference from historical indicator statuses with new rounds of inspections and lower power consumption.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] In the pre-production processes of batteries such as power lithium batteries and energy storage battery electrodes, the powder and solvent used to manufacture the battery electrodes need to be mixed in a mixer. After stirring and dispersing in the mixer, a uniform slurry is formed. The slurry is pumped from the mixer to a transfer tank through a slurry pipeline, and then from the transfer tank to the coating head for the coating process. The mixer, transfer tank, and buffer tank of the coating head are connected sequentially by pipelines. Each pipeline is equipped with a separate ball-pushing system, which uses positive pressure to push the balls and clean the pipeline of residual slurry to prevent blockage. However, the slurry can gel and block the pipeline, causing the cleaning ball to get stuck in the pipeline during the ball-pushing process. It is necessary to disassemble and clean the corresponding blocked pipeline.

[0034] Currently, manual inspection is used to clear pipe blockages. Workers use handheld inspection devices to locate the blockages, which is inefficient and poses safety hazards due to the high position of the slurry pipes.

[0035] Based on the above problems, this embodiment provides a slurry pipeline blockage detection system. By setting at least one detection unit at intervals on the outer wall of the pipeline, the detection unit includes an indicator module. The detection unit detects the position of the pigging ball. When the pigging ball passes the detection unit, the indicator module is controlled to be in display mode, which can reflect the position of the pigging ball in real time. No manual detection is required, which improves detection efficiency and production safety.

[0036] The slurry pipeline blockage detection system of some embodiments of this application can be applied to different industries or different types of slurry. For ease of explanation, this embodiment takes a battery production slurry system as an example.

[0037] Figure 1 A schematic diagram of the slurry pipeline blockage detection system of this application is shown. Figure 1 As shown in the embodiments of this application, the slurry pipeline blockage detection system includes: at least one detection unit 103, which is spaced apart along the outer wall of the pipeline 101; a cleaning ball 102 is disposed inside the pipeline 101, which is configured to move within the pipeline 101; the detection unit 103 includes an indicator module, which is configured to control the indicator module to change the indicator state when the cleaning ball 102 passes through the detection unit 103.

[0038] In this embodiment, the detection unit 103 can be a magnetic induction unit. The pigging ball 102 is magnetic, and during the movement of the pigging ball 102, the magnetic induction effect drives the indicator module to change the indicator state. In this embodiment, the indicator state can be that the indicator module is in a display state or in a non-display state. The indicator module changing the indicator state can be from a display state to a non-display state or from a non-display state to a display state.

[0039] In one example, the detection unit 103 can also be a radio frequency unit. The cleaning ball 102 has a built-in radio frequency coil. Then, during the movement of the cleaning ball 102, when the distance between the radio frequency coil of the cleaning ball 102 and the detection unit 103 is within the radio frequency range, the driving indicator module changes the indicator state, such as driving the indicator module from a non-display state to a display state.

[0040] In one example, the detection unit 103 can also be an ultrasonic unit, which detects the position of the cleaning ball 102 by detecting the sound emitted by the cleaning ball 102 moving inside the tube, and then drives the indicator module to change the indicator state.

[0041] The detection unit 103 can also be other signal conversion units that utilize signals such as pressure, flow, and capacitance to convert the position signal of the pigging ball 102 into a driving signal for the indicator module, and will not be listed here.

[0042] Figure 2 This diagram illustrates one structural schematic of the detection unit of this application. For example... Figure 2 As shown, the detection unit 103 includes an indicator module 104. In this embodiment, the indicator module 104 refers to a visual module that can change its state. The indicator module 104 is, for example, a light-emitting module that can emit light, or a display screen that can display information, etc., which can change its own state after being triggered. For example, it is off in the non-triggered state and lit up after being triggered.

[0043] In this embodiment, at least one detection unit 103 is provided at intervals on the outer wall of the pipeline 101. The detection unit 103 includes an indicator module 104. The position of the pigging ball 102 is detected by the detection unit 103. When the pigging ball 102 passes the detection unit 103, the indicator module 104 is controlled to be in display mode, which can reflect the position of the pigging ball 102 in real time. No manual detection is required, which improves detection efficiency and production safety.

[0044] In this embodiment of the application, the pigging ball 102 is magnetic, and the detection unit 103 includes a magnetic induction switch 105. The magnetic induction switch 105 of each detection unit 103 is coupled to the indicator module 104. The magnetic induction switch 105 is configured to drive the indicator module 104 to change the indicator state under the magnetic induction of the pigging ball 102.

[0045] In this embodiment, the pigging ball 102 is magnetic, and the detection unit 103 includes a magnetic induction switch 105, which can detect the position of the pigging ball 102 using the principle of magnetic induction. The magnetic signal is not affected by the material of the pipeline 101 and has high reliability.

[0046] Each detection unit 103 has a magnetic induction switch 105 coupled to an indicator module 104. Thus, when a magnetic induction switch 105 of a certain detection unit 103 detects a magnetic signal, it can drive the indicator module 104 coupled to the magnetic induction switch 105 to change the indicator state, thereby indicating the specific position of the current pig 102.

[0047] This embodiment utilizes the principle of magnetic induction to detect the position of the pigging ball 102. It has high sensitivity, strong anti-interference ability, and can achieve non-contact detection, thereby improving reliability and reducing maintenance costs.

[0048] In this embodiment, the magnetic induction switch 105 includes a Hall switch.

[0049] Hall switches can output electrical signals in response to changes in magnetic fields. In this embodiment, the magnetic induction switch 105 adopts a Hall switch, which enables the detection unit 103 to have miniaturization and fast response characteristics, and can achieve high-density arrangement and real-time response, thereby improving detection accuracy and system compactness.

[0050] In this embodiment of the application, the indicator module 104 includes at least one light-emitting device, and the light-emitting devices of multiple indicator modules 104 form a light-emitting strip. The light-emitting strip includes multiple segments, and adjacent segments of the light-emitting strip are detachably connected.

[0051] In this embodiment, one or more light-emitting strips can be provided on each section of pipe 101 according to the characteristics of pipe 101. The light-emitting strips are composed of multiple light-emitting devices, such as LED lights.

[0052] The indicator module 104 includes at least one light-emitting device and can be applied to different magnetic induction switches 105. For example, when the indicator module 104 includes one light-emitting device, it can be applied to a single-pole magnetic induction switch 105, and when the indicator module 104 includes two light-emitting devices, it can be applied to a dual-pole magnetic induction switch 105.

[0053] In this embodiment, the two adjacent light-emitting strips are detachably connected. For example, a snap-fit ​​device is provided between the two adjacent light-emitting strips, which can realize quick snap-fit ​​and quick disassembly between the two adjacent light-emitting strips. Thus, when the pipe 101 is blocked, the blocked pipe 101 can be disassembled and repaired, reducing maintenance costs.

[0054] In this embodiment, the light-emitting strip includes multiple segments. The detachable connection between adjacent light-emitting strip segments can improve the adaptability of the slurry pipe 101 blockage detection system, making it applicable to pipes 101 of different lengths / shapes. Furthermore, the detachable connection between adjacent light-emitting strip segments can achieve quick disassembly in segments, simplifying the installation and disassembly process.

[0055] In this embodiment, the magnetic induction switch 105 includes a single magnetic pole detection switch, and each single magnetic pole detection switch is connected to a light-emitting device.

[0056] The pigging ball 102 is magnetic. Different types of magnets have different magnetic poles. For a single-pole magnet, it can be either an N pole or a S pole. For a dual-pole magnet, it has both an N pole and a S pole.

[0057] like Figure 2 As shown, a single magnetic pole detection switch is connected to a light-emitting device, that is, the detection unit 103 can detect a single magnetic pole of the magnet. For example, the single magnetic pole detection switch can detect the N pole. When the N pole in the cleaning ball is close to the magnetic induction switch 105, the magnetic induction switch 105 detects a high magnetic field strength of the N pole, which generates an electrical signal and drives the light-emitting device to emit light.

[0058] This embodiment can detect pigging balls with a single magnetic field, and has a simple structure.

[0059] In this embodiment of the application, the magnetic induction switch includes a dual magnetic pole detection switch, which is connected to two light-emitting devices respectively, and the two light-emitting devices are configured to detect different magnetic poles.

[0060] Figure 3 This diagram illustrates another structural schematic of the detection unit of this application. (As shown...) Figure 3 As shown, the dual-pole detection switch is connected to two light-emitting devices, which are used to detect different magnetic poles. That is, the detection unit 103 can simultaneously detect the N pole and S pole of the magnet. In one example, the two light-emitting devices are a first light-emitting device 1041 and a second light-emitting device 1042. Both the first light-emitting device 1041 and the second light-emitting device 1042 are connected to the dual-pole detection switch. When the dual-pole detection switch detects the N pole magnetic field, it generates a first electrical signal, which drives the first light-emitting device 1041 to emit light, while the second light-emitting device 1042 does not emit light. When the dual-pole detection switch detects the S pole magnetic field, it generates a second electrical signal, which drives the second light-emitting device 1042 to emit light, while the first light-emitting device 1041 does not emit light.

[0061] In this embodiment, the single-pole detection switch can detect either the N pole or the S pole, while the dual-pole detection switch can detect either the N pole or the S pole. That is, for a single-pole pigging pneumatic tube, either a single-pole or dual-pole detection switch can be used; for a dual-pole pigging pneumatic tube, a dual-pole detection switch can be used.

[0062] This embodiment can be compatible with pigging balls of different magnetic properties. When the shape of the pipeline 101 changes, the detected magnetic poles may also change. Therefore, this embodiment can also be compatible with different pipeline scenarios, enhancing the applicability of this embodiment.

[0063] In the embodiments of this application, the light-emitting device includes at least one of a monochromatic light-emitting device and a multicolor light-emitting device.

[0064] In this case, a monochromatic light-emitting device is, for example, a lamp of a single color. When no pig passes by, the light-emitting device does not emit light. When the pig passes by, the light-emitting device can light up with the same color to indicate that the pig has passed this point.

[0065] Multi-color light-emitting devices, such as RGB multi-color LEDs, can assign different colors to represent different states. For example, red indicates the current position of the pig, green indicates the normal direction of movement, and blue indicates a potential risk of jamming.

[0066] In one example, the different colors of a multi-color light-emitting device can distinguish the type of magnetic pole; for example, red represents N-pole triggering and green represents S-pole triggering.

[0067] In this embodiment, the light-emitting device includes at least one of a monochromatic light-emitting device and a multicolor light-emitting device. The monochromatic or multicolor light-emitting characteristics of the light-emitting device can be used to characterize different state information, which helps the staff to intuitively judge the position of the cleaning ball and thus determine whether the pipeline is blocked.

[0068] In this embodiment, at least one detection unit 103 is arranged at equal distances; in each detection unit 103, the distance between the magnetic induction switch 105 and the light-emitting device is less than a preset distance.

[0069] At least one detection unit 103 is set at equal intervals to facilitate the calculation of the distance between the current position and the starting position of the cleaning ball. For example, the distance between each detection unit 103 is L. If the indicator module 104 of the Nth detection unit 103 is lit up, the distance between the cleaning ball and the starting position is the product of L and N, thereby determining the location of the currently blocked pipeline.

[0070] In each detection unit 103, the distance between the magnetic induction switch 105 and the light-emitting device is less than a preset distance, which can realize the synchronization of the pig position and the display position, reduce signal delay, reduce position deviation, and improve detection accuracy.

[0071] In this embodiment of the application, the system further includes a controller (not shown in the figure), which is electrically connected to the detection unit 103. The controller is configured to determine the position information of the pigging ball based on the position and indication status of each indication module 104 in the detection unit 103, and to display the status information of each indication module 104. The controller is also configured to control the indication modules 104 of all detection units 103 to reset when the pigging ball is located at both ends of the pipeline.

[0072] In this embodiment, the controller can acquire the electrical signal from the magnetic induction switch 105 in the detection unit 103, such as the electrical signal triggered by a Hall switch, and determine the current position of the pig based on the electrical signal and the position of the indicator module 104 (that is, the position of the detection unit 103). For example, the controller assigns a unique position code (such as coordinate value or pipeline segment number) to each detection unit 103. Each detection unit 103 is set at equal intervals with a spacing of 1 meter. If the 5th detection unit 103 lights up, the controller determines that the pig is located 5 meters from the starting point. In this embodiment, the controller can be a microcontroller or MCU, or other device with signal processing and control functions.

[0073] Meanwhile, the controller can visualize the status information (off or on) of the indicator module 104 through the display, which improves the human-computer interaction and helps staff quickly determine the current position of the pig.

[0074] When the pigging ball is located at both ends of the pipeline, the controller can reset the indicator modules of all detection units 103. This reduces interference from historical indicator states with the new round of detection and also lowers power consumption.

[0075] The slurry pipeline blockage detection system provided in this embodiment has at least one detection unit 103 set at intervals on the outer wall of the pipeline. The detection unit includes an indicator module. The position of the pig is detected by the detection unit. When the pig passes the detection unit, the indicator module is controlled to change the indicator state. The position of the pig can be reflected in real time without manual detection, which improves detection efficiency and production safety.

[0076] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0077] The slurry pipeline blockage detection method and the slurry pipeline blockage detection system provided in the above embodiments of this application are based on the same application concept and have the same beneficial effects as their operation or implementation methods.

[0078] This embodiment provides a battery production system, including a pipeline, a pigging ball, and the aforementioned slurry pipeline blockage detection system; the pigging ball is disposed inside the pipeline and configured to move within the pipeline; the pipeline is used to convey slurry for manufacturing battery electrodes; the slurry pipeline blockage detection system is used to detect the position of the pigging ball and, based on the position of the pigging ball, determine the pipeline where a blockage has occurred.

[0079] The battery production system provided in this embodiment has at least one detection unit set at intervals on the outer wall of the pipeline for conveying the battery electrode manufacturing slurry. The detection unit includes an indicator module. The position of the pigging ball is detected by the detection unit. When the pigging ball passes the detection unit, the indicator module is controlled to change the indicator state, which can reflect the position of the pigging ball in real time. No manual detection is required, which improves detection efficiency and production safety.

[0080] The battery production system provided in the above embodiments of this application and the slurry pipeline blockage detection system provided in the embodiments of this application are based on the same application concept and have the same beneficial effects as their operation or implementation methods.

[0081] The following is a specific example to illustrate the slurry pipeline blockage detection system, method, and battery production system of this application.

[0082] like Figure 1 As shown, the pigging ball, under the action of the ball pushing system, moves along... Figure 1 Moving in the direction of the arrow, when the pig passes the detection unit, the magnetic induction switch in the corresponding detection unit senses the magnetic field. The magnetic induction switch can be a Hall element. When the magnetic field is perpendicular to the surface of the Hall element, the Lorentz force causes electrons to deflect inside the Hall element. The deflection of the electrons creates a potential difference on both sides of the Hall element, i.e., the Hall voltage. The Hall voltage is amplified and processed by the built-in circuit, and finally outputs an electrical signal proportional to the magnetic field strength. This electrical signal drives the light-emitting device (such as an LED) in the indicator module to light up, thus allowing the position of the pig to be detected in real time.

[0083] At the same time, the display status of the light-emitting device corresponding to each indicator module is displayed on the screen, so that staff can monitor in real time whether there is a blockage in the pipeline.

[0084] When a blockage occurs in the pipeline, the location of the blockage can be quickly determined by the position of the detection unit. In this embodiment, the light-emitting devices of the indicator modules on different pipelines form a light-emitting strip, which consists of multiple segments and is detachably connected to adjacent segments. Therefore, when a blockage occurs in a part of the pipeline, the light strip at the corresponding blockage location can be directly disconnected from the adjacent light strip, enabling rapid blockage removal.
