不锈钢分选机是一种有效的不锈钢破碎料回收方法。气刀分选是一种以电磁探测为基础的分选方法。电磁探测使用基于电涡流效应的金属检测探头来实现，金属检测探头是一种用于金属检测的传感器，能够对目标破碎料进行快速识别并将电压信号传递到控制系统；使用皮带运送破碎料，在分选设备运行前，控制系统需要计算出皮带速度，根据金属检测探头信号和速度信号，经计算处理后确定分选时间，即喷气延时，并控制分选机构的电磁阀在合适时间通电，打开阀口喷气实现分选。分选机构需要配以气源系统不断供应压缩气体以维持内部气压，满足实际生产中不断喷气的要求。
Stainless steel sorting is an effective method for recovering stainless steel crushed materials. Air knife sorting is a sorting method based on electromagnetic detection. Electromagnetic detection is achieved using metal detection probes based on eddy current effects. Metal detection probes are sensors used for metal detection, which can quickly identify target crushed materials and transmit voltage signals to the control system; Before using a belt to transport crushed materials, the control system needs to calculate the belt speed before the sorting equipment runs. Based on the metal detection probe signal and speed signal, the sorting time, namely the jet delay, is determined after calculation and processing. The electromagnetic valve of the sorting mechanism is controlled to be energized at an appropriate time, and the valve port is opened for jet cleaning to achieve sorting. The sorting mechanism needs to be equipped with an air source system to continuously supply compressed gas to maintain internal pressure and meet the requirements of continuous air injection in actual production.
为保证分选动作具有足够的精度和效率，金属检测探头、控制系统和电磁阀需要满足快速响应的特性，从测速、识别、信号处理到分选动作的执行，整个过程的时间不应超过 20ms。鉴于金属检测探头的识别和气刀分选特性，皮带上的待分选破碎料需要均匀分散，避免因为破碎料重叠造成的误选现象，因此分选机需要配备相应的振动送料装置。为实现上述分选功能，分选机需要设置传动控制装置、识别及传感装置、控制系统、分选机构、气源系统。
To ensure sufficient accuracy and efficiency of the sorting action, the metal detection probe, control system, and solenoid valve need to meet the characteristics of fast response. The entire process from speed measurement, recognition, signal processing to the execution of the sorting action should not exceed 20ms. Given the recognition of metal detection probes and the characteristics of air knife sorting, the crushed materials to be sorted on the belt need to be evenly dispersed to avoid misselection caused by overlapping crushed materials. Therefore, the sorting machine needs to be equipped with corresponding vibration feeding devices. To achieve the above sorting function, the sorting machine needs to be equipped with transmission control devices, identification and sensing devices, control systems, sorting mechanisms, and air source systems.
