Description

Monitoring system for a waste secondary battery crushing and grinding device and a waste secondary battery recycling process system using the same

[0001] The present invention relates to a monitoring system and a recycling process system using the same, and more specifically, to an efficient waste secondary battery crushing and grinding device monitoring system capable of preventing accidents and ensuring worker safety, and a waste secondary battery recycling process system using the same.

[0002]

[0003] The secondary battery market, driven by carbon neutrality, has also seen rapid growth in the secondary battery cell recycling market. Secondary battery cells are composed of powdered cathode and anode materials, copper foil, aluminum foil, separators, and cases. Separating these components for recycling requires shredding, grinding, and sieving processes.

[0004] Figure 1 is a schematic diagram showing the process of a conventional recycling process system for waste secondary batteries, and Figure 2 is a drawing illustrating a main crushing and grinding device used in a conventional recycling process system for waste secondary batteries.

[0005] As shown in Fig. 1, the conventional waste secondary battery recycling process discharges battery cells through salt water discharge, performs the first crushing (shredder), second crushing (cut crusher), and third crushing (hammer mill) processes, then performs a magnetic separation process to separate magnetic materials, separators, foils, etc. from the crushed battery cells, and performs a heat treatment process to leach black mass.

[0006] Since secondary batteries have a structure in which aluminum foil coated with a positive electrode material, copper foil coated with a negative electrode material, and a separator are stacked in layers, a mechanism that cuts or tears by applying shear force rather than compression or impact is more suitable for crushing secondary batteries.

[0007] Therefore, in recycling waste secondary batteries, shear force crushers such as shredders and cut crushers are mainly used.

[0008] Here, as shown in Fig. 2, the shredder is most commonly used for primary crushing of printed circuit boards or PET bottles in urban mines, as it cuts by double interlocking teeth, and the cut crusher is a device designed with a mechanism that has a fixed blade and a rotating blade that rotates at high speed to apply shearing force, and is used as a secondary crusher after the shredder, and the cut crusher has a screen at the discharge port, so that when the material is crushed to a size smaller than the screen hole, the crushed material is discharged.

[0009] In addition, in order to recover black mass from waste secondary battery products shredded by a shear force shredder, it is advantageous to apply impact to the foil to shake off the applied powder, so a hammer mill or pin mill capable of applying impact is mainly used for the third shredding.

[0010] A hammer mill is a crusher that applies impact to the material fed in as the hammer rotates. There is a screen at the discharge port, and when the material is crushed to a size smaller than the screen hole, the crushed material is discharged.

[0011] Secondary battery crushing and pulverization is a process that consumes a lot of energy, and it is a very hazardous equipment for safety, as it can cause operators to get caught or get caught when working nearby with heavy equipment.

[0012] However, there is a problem in that it is difficult to install a camera due to the structure of the equipment, as the raw material may not be crushed to a size smaller than the screen hole size in the case of cut crushers and hammer mills, and the overload or blockage of the process must be observed in a situation where the safety of the operator is ensured.

[0013] In addition, the conventional ball mill monitoring system can only monitor ball mills that generate possible noise and vibration, and has the problem that it is difficult to apply it to shear force crushers and grinders such as shredders, cut crushers, and hammer mills used in recycling waste secondary batteries.

[0014]

[0015] The purpose of the present invention to solve the above-mentioned conventional problems is to provide an efficient waste secondary battery crushing and pulverizing device monitoring system and a waste secondary battery recycling process system using the same, which can detect malfunctions of the device in advance through the function of a system that monitors the power of the crushing device in real time, and can prevent accidents and ensure the safety of workers by setting a threshold value for power consumption.

[0071]

[0072] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

[0073] FIG. 3 is a drawing showing a block configuration of a waste secondary battery crushing and pulverizing device monitoring system (100) according to an embodiment of the present invention, and FIG. 4 is a drawing showing a process schematic diagram of a waste secondary battery crushing and pulverizing device monitoring system (100) according to an embodiment of the present invention.

[0074] As shown in FIG. 3, a waste secondary battery crushing and pulverizing device monitoring system (100) according to an embodiment of the present invention may be configured to include a crushing device including a crushing device (110) and a crushing device (130), a power meter (112, 116, 132) for measuring the power of the crushing device, and a monitoring device (150) for receiving a signal measured by the power meter (112, 116, 132) and monitoring the operation of the crushing device through real-time power analysis.

[0075] Here, the shredding device may be configured to include a shredding device (110) for shredding waste secondary batteries, as shown in Fig. 4, and a crushing device (130) for crushing the shredded waste secondary batteries.

[0076] The crushing device (110) is configured to include a Schröder device and a cut crusher (115) device, and the crushing device (130) may be a hammer mill (131) or a pin mill device.

[0077] In this way, the shredding device is a main device used to process waste secondary batteries, and can be configured to include two main components: a shredding device (110) and a crushing device (130).

[0078] The shredding device (110) may be a device such as a shredder device and a cut crusher (115) device, which may be a shredding device that uses a mechanism that applies a shear force to cut or tear the battery in order to perform the role of breaking down the waste secondary battery into small pieces.

[0079] The crushing device (130) further processes the waste battery pieces after crushing in the crushing device, which may include a hammer mill (131) or a pin mill, and can crush the crushed material into finer particles.

[0080] And, as shown in FIGS. 3 and 4, the power meter (112, 116) may be configured to include a first power meter (112) mounted on the shredding device (110) and measuring power, and a second power meter (132) mounted on the crushing device (130) and measuring power.

[0081] Here, the power meter (112, 116, 132) is an instrument that measures the electric circuit of direct current or alternating current, and is a device that measures the power of the electric circuit that drives the shredding device (110) and the crushing device (130).

[0082] As shown in Fig. 4, power meters (112, 116, 132) are installed in each shredding device (110) and crushing device (130) to measure the power generated when the device is operated. That is, by measuring the power used to operate the device, signal data for determining the operating status or operation status can be secured.

[0083] And, as shown in FIGS. 3 and 4, the monitoring device (150) is a computing device that receives and analyzes power data from the power meter (112, 116, 132) and outputs the analyzed result information, and can analyze power in real time to monitor the operating status of the shredding and crushing device.

[0084] In addition, the monitoring device (150) may be configured to compare the operating status reference information of the shredding device, which is generated by interpreting a power graph pattern over time in advance, with the real-time power measurement information of the shredding device, to derive the current operating status result information of the shredding device.

[0085] Here, the operating status reference information may include at least one of operating on-off status information generated by classifying the operating status appearing in the power graph pattern appearing during the operation of the shredding device, information on the type of the shredding device, information on the shredding status due to the operation, information on the failure status of the device due to the operation, and warning notification information due to the operation.

[0086] That is, the monitoring device (150) can determine the current operating status of the device machine by comparing real-time power data with a preset power pattern. This may include determining whether the device is on or off, operating efficiency, and potential problems such as blockages or mechanical failures.

[0087] Additionally, the monitoring device (150) may, based on the analysis results, generate and display warning or alert information about operational abnormalities, such as excessive power consumption, which may indicate a malfunction or safety hazard.

[0088]

[0089] FIG. 5 is a drawing showing a block configuration of a waste secondary battery recycling process system (1000) using a crushing and pulverizing device monitoring system (100) as another embodiment of the present invention.

[0090] As shown in FIG. 5, a waste secondary battery recycling process system (1000) using a crushing and pulverizing device monitoring system (100) according to an embodiment of the present invention may be configured to include a discharge unit (50), a crushing unit (100), and a sorting unit (200).

[0091] Here, the discharge unit (50) may be a device configuration that performs a salt water discharge method as a process device for completely discharging a waste secondary battery cell.

[0092] The crushing unit (100) may be configured as a device for first crushing (shredder (111)), second crushing (cut crusher (115)), and third crushing (hammer mill (131)) or crushing discharged waste secondary battery cells.

[0093] The sorting unit (200) may be a device for sorting components for recycling, including a process device that magnetically sorts battery cells crushed in the crushing unit (100) into magnetic materials, separators, foils, etc., and a process device that extracts black mass through heat treatment.

[0094] As described above, the waste secondary battery recycling process system (1000) according to the embodiment of the present invention has its feature in the waste secondary battery crushing and pulverizing device monitoring system (100), so the configuration of the corresponding crushing unit (100) is as described above, and therefore a detailed description thereof will be omitted.

[0095]

[0096] FIG. 6 is an example of a UI screen for monitoring a real-time power measurement signal of a shredding and crushing device in a waste secondary battery shredding and crushing device monitoring system (100) according to an embodiment of the present invention.

[0097] As shown in Fig. 6, the measured real-time power is displayed in a graph when the shredder (111) is used, the cut crusher (115) is used, and the hammer crusher is used. It can be clearly seen that the shredder can be efficiently and safely monitored by monitoring the real-time graph pattern by comparing it with the operating status reference information according to the graph pattern prepared in advance.

[0098] That is, the monitoring system (100) for a waste secondary battery crushing and pulverizing device according to an embodiment of the present invention utilizes a power meter (112, 116, 132), so that it can remotely check whether the power of the equipment is turned on, and by measuring the amount of power change over time, the operator can easily check the start and end times of battery crushing and pulverization.

[0099] The crushing energy can be quantitatively calculated by the following [Mathematical Formula 1].

[0100]

[0101]

[0102]

[0103] Here, W s represents the specific energy consumption (kW / h), t0 represents the time when shredding started (minutes), t1 represents the time when shredding ended (minutes), and P L represents the no-load power reading (kW) and m represents the mass of the shredded battery cell (g).

[0104]

[0105] FIG. 7 is a graph showing the power consumption of a Schroeder during the crushing of a battery cell measured in a waste secondary battery crushing and pulverizing device monitoring system (100) according to an embodiment of the present invention, FIG. 8 is a graph showing the power consumption of a cut crusher (115) during the crushing of a battery cell measured in a waste secondary battery crushing and pulverizing device monitoring system (100) according to an embodiment of the present invention, and FIG. 9 is a graph showing the power consumption of a hammer mill (131) during the crushing of a battery cell measured in a waste secondary battery crushing and pulverizing device monitoring system (100) according to an embodiment of the present invention.

[0106] As shown in Fig. 7, the start and end points of shredding due to battery cell input can be easily identified by measuring the power consumption or power change of the shredder (111) while shredding a single battery cell. The measured shredding energy was found to be 1.42 Wh / kg.

[0107] In addition, as shown in Fig. 8, it was observed that the cut crusher (115) measured high power at the initial stage of turning on the equipment because the rotating blade rotates at high speed.

[0108] In addition, it can be seen that the cut crusher (115) has a long processing time and is affected by the feed rate because the discharge port is blocked by a screen, unlike the shredder (111), and the crushing energy was measured to be 5.0 Wh / kg, which is higher than that of the shredder (111).

[0109] In addition, as shown in Fig. 9, it can be seen that a phenomenon in which high power is measured at the time the equipment is turned on is observed because the rotary blade of the hammer mill (131) rotates at high speed, similar to the cut crusher (115).

[0110] Hammermill (131) shows two graphs: one for a battery cell that was not heat-treated and one for a battery cell whose separator was hardened through heat treatment at approximately 200°C. In the case of the unheated battery cell, the separator (blue) blocked the sieve pores, generating high fracture energy, and no fracture end point was observed. Furthermore, when calculating fracture energy based on the point at which the device was turned off, a high energy of 16.04 Wh / kg was observed.

[0111] In battery cells with hardened separators through heat treatment, no clogging occurred, indicating a termination point. The calculated fracture energy was 9.16 Wh / kg, a lower fracture energy than that of unheated batteries.

[0112] That is, it can be seen that the phenomenon of equipment blockage is observed through the waste secondary battery crushing and pulverizing device monitoring system (100) according to the embodiment of the present invention, and through this, the operator can confirm whether the process is being operated stably.

[0113]

[0114] FIG. 10 is a graph showing an example of an operating state power pattern of a waste secondary battery shredding and crushing device monitoring system (100) according to an embodiment of the present invention, and FIG. 11 is a graph showing an example of power data during Schroeder shredding according to battery type in a waste secondary battery shredding and crushing device monitoring system (100) according to an embodiment of the present invention.

[0115] In case of constriction or jamming in the crusher, the power consumption of the motor increases due to overload compared to the normal operating power.

[0116] Therefore, as shown in Fig. 10, when the waste secondary battery crushing and pulverizing device monitoring system (100) according to the embodiment of the present invention is applied, a warning notification is given to the operator when the daily operating maximum power exceeds 10%, thereby ensuring the safety of the operator.

[0117] Additionally, safety accidents can be prevented through upgrades such as applying an algorithm that automatically stops the machine when the excess exceeds 30% compared to the existing one.

[0118] Furthermore, as illustrated in FIG. 11, the waste secondary battery crushing and grinding device monitoring system (100) according to an embodiment of the present invention can distinguish the types of battery cells in waste secondary batteries, thereby standardizing data on power by battery type by storing the collected power data in a database. From this data, it can recommend a suitable battery type for recycling and inform the manufacturer, thereby also being applied to improving the efficiency of the recycling system.

[0119]

[0120] In this way, the waste secondary battery crushing and grinding device monitoring system (100) according to the embodiment of the present invention and the waste secondary battery recycling process system (1000) using the same have the following advantages.

[0121] 1) Improved safety: The system's function of monitoring the power of the crusher in real time enables early detection of device malfunctions such as jamming or entrapment, and setting thresholds for power consumption (e.g., warning when exceeding 10% of normal operation, automatic shutdown when exceeding 30%) can prevent accidents and ensure worker safety.

[0122] 2) Operational Efficiency: Real-time monitoring of power can help maintain the efficiency of the shredding and crushing process, and by understanding power usage patterns, operators can optimize equipment operation, reducing downtime and improving throughput.

[0123] 3) Predictive maintenance: The waste secondary battery crushing and grinding device monitoring system (100) according to the present invention can identify patterns that may indicate impending equipment failure, thereby enabling predictive maintenance to replace or repair parts before failure occurs, thereby reducing unexpected downtime and extending the life of the equipment.

[0124] 4) Energy Management: The system according to the present invention can track the energy consumption of the shredding and crushing device to identify areas where energy usage can be reduced, which can lead to cost savings and environmentally friendly operation.

[0125] 5) Data Collection and Analysis: The data collection and analysis capabilities of the system according to the present invention not only provide long-term benefits, but this data can be used to standardize power consumption metrics for various battery types, leading to a more efficient recycling process. It can also provide valuable insights for battery manufacturers to design batteries more suitable for recycling.

[0126] 6) Customization and Scalability: The system according to the present invention can be adapted to various types of shredding and crushing equipment, making it versatile and expandable for various recycling operations.

[0127] 7) Quality Control: The system according to the present invention can help maintain the quality of the recycled material by ensuring that the shredding and crushing process operates within optimal parameters, which can be very important for its subsequent use in manufacturing.

[0128] 8) Environmental Impact: The system according to the present invention can not only make the recycling process more efficient, but also contribute to reducing hazardous waste and preserving valuable resources, as efficient recycling of waste secondary batteries is very important for environmental protection.

[0129]

[0130] Above, although some examples have been given and various preferred embodiments of the present invention have been described, the description of the various embodiments described in the “Specific Details for Carrying Out the Invention” section is merely exemplary, and those skilled in the art to which the present invention pertains will readily understand that they can carry out various modifications of the present invention or carry out equivalent implementations of the present invention based on the above description.

[0131] In addition, since the present invention can be implemented in various other forms, the present invention is not limited by the above description, and the above description is provided only to make the disclosure of the present invention complete and to fully inform a person having ordinary skill in the art to which the present invention belongs of the scope of the present invention, and it should be understood that the present invention is defined only by each claim of the claims.
