Description
本发明涉及锂电池材料技术领域,特别涉及一种正极材料烧结车间内磁性颗粒物的处理方法及处理系统。The invention relates to the technical field of lithium battery materials, and in particular to a method and system for processing magnetic particles in a sintering workshop of positive electrode materials.
金属磁性颗粒物(下称磁性颗粒物)是锂电池正极材料的一种常见杂质,其中的单质铁往往易引起电池自放电、电池过充等问题,甚至引发电池短路。通常情况下,磁性颗粒物主要在正极材料制备过程中通过原料带入、金属设备磨损后带入,并在生产过程中泄露至生产环境,此时,悬浮在车间生产环境中的磁性颗粒物可能会进入成品正极材料内,导致成品磁性颗粒物超标,进而影响产品质量。因此,在做成电池级正极材料前,需要对车间环境进行除磁处理。Metallic magnetic particles (hereinafter referred to as magnetic particles) are a common impurity in lithium battery cathode materials. The elemental iron in them can easily cause battery self-discharge, battery overcharging and other problems, and even cause battery short circuit. Normally, magnetic particles are mainly brought in through raw materials during the preparation of cathode materials, brought in after the wear and tear of metal equipment, and leaked into the production environment during the production process. At this time, magnetic particles suspended in the workshop production environment may enter In the finished cathode material, the magnetic particles in the finished product exceed the standard, thus affecting product quality. Therefore, before making battery-grade cathode materials, the workshop environment needs to be demagnetized.
然而,普通车间一般仅需控制粉尘,其主要以滤网除尘的方式控制环境中的粉尘含量,滤网的过滤标准为G4,孔径为10微米。但对于正极材料烧结车间而言,悬浮粉尘中的磁性颗粒物粒度通常小于10微米,这使得大部分磁性颗粒物易随着循环风回到车间,而无法被滤网过滤清除。However, ordinary workshops generally only need to control dust, and they mainly use filter dust removal to control the dust content in the environment. The filtration standard of the filter is G4 and the pore size is 10 microns. However, for cathode material sintering workshops, the size of magnetic particles in suspended dust is usually less than 10 microns, which makes most of the magnetic particles easy to return to the workshop with the circulating air and cannot be filtered and removed by the filter.

本部分将详细描述本发明的具体实施例,本发明之较佳实施例在附图中示出,附图的作用在于用图形补充说明书文字部分的描述,使人能够直观地、形象地理解本发明的每个技术特征和整体技术方案,但其不能理解为对本发明保护范围的限制。This section will describe the specific embodiments of the present invention in detail. The preferred embodiments of the present invention are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand the present invention. Each technical feature and overall technical solution of the invention shall not be construed as limiting the scope of protection of the invention.
考虑现有的车间粉尘控制方法并无法应用到正极材料烧结车间内金属磁性颗粒物的处理中,本发明一个实施例提供一种正极材料烧结车间内磁性颗粒物的处理方法,包括下述步骤S1至S3。Considering that existing workshop dust control methods cannot be applied to the treatment of metal magnetic particles in the cathode material sintering workshop, one embodiment of the present invention provides a method for processing magnetic particles in the cathode material sintering workshop, including the following steps S1 to S3 .
S1:持续获取车间内的环境数据,所述环境数据包括空气湿度和磁性颗粒物浓度。S1: Continuously acquire environmental data in the workshop, including air humidity and magnetic particle concentration.
S2:若当前空气湿度大于等于预设的第一湿度阈值、且当前磁性颗粒物浓度大于等于预设的浓度上限阈值,控制车间内除磁装置启动,运行预设时间后, 控制除磁装置停止运行。S2: If the current air humidity is greater than or equal to the preset first humidity threshold, and the current magnetic particle concentration is greater than or equal to the preset concentration upper limit threshold, control the demagnetization device in the workshop to start, and after running for the preset time, control the demagnetization device to stop running. .
S3:当除磁装置停止运行后,控制车间内除湿装置启动,直至当前空气湿度小于湿度标准值、且当前磁性颗粒物浓度小于浓度标准值,控制除湿装置停止运行。S3: When the demagnetization device stops running, control the dehumidification device in the workshop to start until the current air humidity is less than the humidity standard value and the current concentration of magnetic particles is less than the concentration standard value, and the dehumidification device is controlled to stop running.
其中,所述湿度标准值小于所述第一湿度阈值,所述浓度标准值小于所述浓度上限阈值。Wherein, the humidity standard value is less than the first humidity threshold, and the concentration standard value is less than the concentration upper limit threshold.
需要说明的是,由于空气湿度与悬浮颗粒物降沉运动之间存在关联关系,故相较于在当前磁性颗粒物浓度大于等于浓度上限阈值时控制除磁装置启动,并使其运行至磁性颗粒物浓度小于浓度标准值停止时所使用的独立除磁时间,本发明实施例所设置的除磁装置运行的预设时间为一个小于所述独立除磁时间的数值,以达到降低除磁设备的运行时间,节约能耗的效果。It should be noted that due to the correlation between air humidity and the settling movement of suspended particles, compared with controlling the startup of the demagnetization device when the current concentration of magnetic particles is greater than or equal to the upper concentration threshold, and operating it until the concentration of magnetic particles is less than The independent demagnetization time used when the concentration standard value is stopped. The preset time for the operation of the demagnetization device set in the embodiment of the present invention is a value smaller than the independent demagnetization time, so as to reduce the operation time of the demagnetization equipment. The effect of saving energy consumption.
在本实施例中,若当前空气湿度大于等于预设的第二湿度阈值、且当前磁性颗粒物浓度小于预设的浓度上限阈值,控制除湿设备启动,直至当前空气湿度小于湿度标准值,控制除湿设备停止运行;若当前空气湿度小于预设的第二湿度阈值、且当前磁性颗粒物浓度大于等于预设的浓度上限阈值,则控制除磁设备启动,直至当前磁性颗粒物浓度小于浓度标准值,控制所述除磁设备停止运行。其中,所述第二湿度阈值大于所述第一湿度阈值。In this embodiment, if the current air humidity is greater than or equal to the preset second humidity threshold and the current magnetic particle concentration is less than the preset concentration upper limit threshold, the dehumidification equipment is controlled to start until the current air humidity is less than the humidity standard value, the dehumidification equipment is controlled Stop running; if the current air humidity is less than the preset second humidity threshold and the current magnetic particle concentration is greater than or equal to the preset concentration upper limit threshold, then control the degaussing equipment to start until the current magnetic particle concentration is less than the concentration standard value, control the The degaussing equipment has stopped operating. Wherein, the second humidity threshold is greater than the first humidity threshold.
优选的,空气湿度的第一湿度阈值为60%,第二湿度阈值为66%,湿度标准值为58%;磁性颗粒物的浓度上限阈值被设置为40pcs/kg,浓度标准值为30pcs/kg,除磁设备运行时间为10分钟。其中,浓度标准值依据锂电池质量管理标准确定。Preferably, the first humidity threshold of air humidity is 60%, the second humidity threshold is 66%, and the humidity standard value is 58%; the concentration upper limit threshold of magnetic particles is set to 40pcs/kg, and the concentration standard value is 30pcs/kg. The running time of the degaussing equipment is 10 minutes. Among them, the concentration standard value is determined according to the lithium battery quality management standards.
需要说明的是,基于上述优选值,参考实验数据和经验信息可得,当当前空气湿度大于等于60%、且当前磁性颗粒物浓度大于等于40pcs/kg时,若同时启动除湿装置和除磁装置,所述除磁装置至少需运行35分钟才可使得磁性颗粒物浓度降至30pcs/kg;若仅运行除磁装置,则至少需运行50分钟才可使得磁性颗粒物浓度降至30pcs/kg;而若仅运行除湿装置,由于除湿所需时间较短,当湿度达到标准值时,磁性颗粒物浓度往往还无法下降至标准值,因此,本发明实施例通过对湿度和磁性颗粒物进行协同控制,可有效降低除磁装置的运行时间,提升除磁效率。It should be noted that based on the above preferred values and with reference to experimental data and empirical information, when the current air humidity is greater than or equal to 60% and the current magnetic particle concentration is greater than or equal to 40pcs/kg, if the dehumidification device and the demagnetization device are started at the same time, The demagnetization device needs to run for at least 35 minutes to reduce the concentration of magnetic particles to 30pcs/kg; if only the demagnetization device is run, it needs to run for at least 50 minutes to reduce the concentration of magnetic particles to 30pcs/kg; and if only the demagnetization device is run, the concentration of magnetic particles can be reduced to 30pcs/kg. When the dehumidification device is operated, due to the short time required for dehumidification, when the humidity reaches the standard value, the concentration of magnetic particles often cannot be reduced to the standard value. Therefore, the embodiment of the present invention can effectively reduce the dehumidification by cooperatively controlling the humidity and magnetic particles. The running time of the magnetic device is improved to improve the demagnetization efficiency.
进一步地,对于磁性颗粒物浓度的获取,可利用收集装置定期收集车间内空气中的磁性物质,再通过清洁度分析仪识别所收集的磁性物质中的目标磁性颗粒物,并检测目标磁性颗粒物的颗粒数,最后根据目标磁性颗粒物的颗粒数确定车间内的磁性颗粒物浓度。Furthermore, to obtain the concentration of magnetic particles, a collection device can be used to regularly collect magnetic materials in the air in the workshop, and then the cleanliness analyzer can be used to identify the target magnetic particles in the collected magnetic materials and detect the number of particles of the target magnetic particles. , and finally determine the concentration of magnetic particles in the workshop based on the number of target magnetic particles.
具体地,所述收集装置被设置于正极材料烧结车间内窑炉的窑头和/或窑尾 处,具体包括风机、风管和电磁吸附设备。其中,风机用于在设定的监测周期内抽取车间内环境空气,风管和电磁吸附设备用于吸附所抽取空气中的磁性物质,并将吸附的磁性物质落入清洁度分析仪托盘内,以使清洁度分析仪对其进行检测,从而得到准确磁性颗粒物浓度信息。其中,磁性颗粒物浓度的监测周期可设定为4小时。Specifically, the collection device is arranged at the kiln head and/or kiln end of the kiln in the cathode material sintering workshop, and specifically includes a fan, air duct and electromagnetic adsorption equipment. Among them, the fan is used to extract the ambient air in the workshop within the set monitoring period, and the air duct and electromagnetic adsorption equipment are used to absorb the magnetic substances in the extracted air, and drop the adsorbed magnetic substances into the cleanliness analyzer tray. So that the cleanliness analyzer can detect it and obtain accurate magnetic particle concentration information. Among them, the monitoring period of magnetic particle concentration can be set to 4 hours.
对于空气湿度的获取则可通过设置于车间内的湿度传感器采集得到。The air humidity can be obtained through the humidity sensor installed in the workshop.
在本实施例中,当空气湿度大于等于第一湿度阈值,或磁性颗粒物浓度大于等于浓度上限阈值时,还可控制车间的报警硬件发出预警信号,以便车间工作人员及时发现湿度超标或磁性颗粒物浓度超标情况。所述报警硬件可为声报警装置或关报警装置。In this embodiment, when the air humidity is greater than or equal to the first humidity threshold, or the concentration of magnetic particles is greater than or equal to the upper concentration threshold, the alarm hardware in the workshop can also be controlled to issue an early warning signal so that workshop staff can promptly detect excessive humidity or magnetic particle concentration. Excessive conditions. The alarm hardware may be an audible alarm device or a shut-off alarm device.
对于除磁装置和除湿装置的配置,本实施例优选的除湿装置包括加热模块和除湿风机,所述除湿风机的送风管道与车间内窑炉抽风设备接驳,当湿度检测超标时,启动除湿风机,使其向车间地面及各区域输送热风,快速干燥车间环境。Regarding the configuration of the demagnetization device and the dehumidification device, the preferred dehumidification device in this embodiment includes a heating module and a dehumidification fan. The air supply duct of the dehumidification fan is connected to the kiln exhaust equipment in the workshop. When the humidity detection exceeds the standard, dehumidification is started. The fan can deliver hot air to the workshop floor and various areas to quickly dry the workshop environment.
除磁装置则包括抽风除尘设备、便携式除磁设备、固定式除磁设备和移动除磁设备。其中,固定式除磁设备被设置于车间的各角落处,移动除磁设备可配置为自动除磁清扫车,以对车间地面进行清洁除磁。Degaussing equipment includes exhaust dust removal equipment, portable degaussing equipment, fixed degaussing equipment and mobile degaussing equipment.

The demagnetizing cavity 200 is provided with an electromagnetic plate 100 . The demagnetization part is usually arranged on the air duct of the demagnetization device, so that the flow chamber 300 of the demagnetization part is connected with the air duct. After the demagnetization gas enters the flow chamber 300 from the inlet of the demagnetization part in direction A, it changes the flow direction at the position of the demagnetization chamber 200 and flows out of the demagnetization chamber 200 in direction B, thereby quickly reducing the concentration of large magnetic particles in the workshop environment. The particles in the gas to be demagnetized collide with the electromagnetic plate 100 due to inertia, thereby enhancing the removal effect.
进一步地,除磁腔200的深度H通常为12-16cm,优选为15cm,其除磁效果佳。Furthermore, the depth H of the demagnetization cavity 200 is usually 12-16 cm, preferably 15 cm, which has a good demagnetization effect.
在一些实施例中,A方向、B方向和C方向平行,且B方向与A方向相反,B方向与出口位置的气流方向C方向同向。但可以理解的是,A方向、B方向、C方向可以为互相不平行的方向指向,且进口气流方向和出口气流方向可以不为同向的方向指向。In some embodiments, the A direction, the B direction and the C direction are parallel, and the B direction is opposite to the A direction, and the B direction is in the same direction as the airflow direction C at the outlet position.

具体地,车间内辊道窑处可每隔1米设置一个温度检测探头;对于需要分区采集温度的区域(如34M窑炉),则可划分为升温区、保温区和降温区三个分区,并在每个分区内设置温度检测探头,对于各分区的温度检测探头所采集的温度数据,可采用平均值作为该区域的最终温度数据。Specifically, a temperature detection probe can be set up every 1 meter at the roller kiln in the workshop; for areas where temperature needs to be collected in zones (such as a 34M kiln), it can be divided into three zones: heating area, heat preservation area and cooling area. And set up a temperature detection probe in each partition. For the temperature data collected by the temperature detection probe in each partition, the average value can be used as the final temperature data of the area.

具体地,当所获取的温度高于温度阈值时,通过制冷机组将冷风持续输入至车间以及各个设备,同时通过第二抽风设备抽出窑炉外溢余热,以达到降低车间温度的目的。Specifically, when the obtained temperature is higher than the temperature threshold, cold air is continuously input to the workshop and various equipment through the refrigeration unit, and at the same time, the kiln overflow waste heat is extracted through the second exhaust device to achieve the purpose of reducing the workshop temperature.
粉尘含量则可通过粉尘监测器实时检测得到,粉尘监测器被设置在车间内所有设备的软连接以及非固定封闭处,当实时检测得到的粉尘含量大于等于粉尘标准值时,控制车间的报警硬件发出预警信号,同时控制除尘装置启动,以确保车间内当前粉尘含量在粉尘标准值以下。The dust content can be detected in real time through the dust monitor. The dust monitor is set at the soft connections and non-fixed closures of all equipment in the workshop. When the dust content detected in real time is greater than or equal to the dust standard value, the alarm hardware of the workshop is controlled.
