[0002] Both strong and weak magnetic minerals can be separated by dry magnetic separators. However, the quality of concentrates and tailings obtained by dry magnetic separators during separation is difficult to guarantee. The main reason is that the equipment operating parameters are not adjusted in time to cope with the fluctuations in the properties of the feed ore. In production, the operating parameters of the dry magnetic separator are often adjusted according to production needs after manual sampling and analysis of concentrates and tailings. The time is very delayed, and the adjustment of equipment parameters cannot keep up with the impact of fluctuations in the properties of the feed ore, resulting in low production efficiency and waste of resources. In addition, with the continuous advancement of large-scale dry magnetic separator equipment, the operating status monitoring system of large-scale equipment is also imperfect, and the equipment reliability is not high. Based on the above background, it is urgent to develop an intelligent sorting dry magnetic separator with intelligent control of sorting indicators and automatic monitoring of equipment operating status.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components.

[0024] like Figure 1 and Figure 2 As shown, the dry magnetic separator generally includes a transmission component 8, a magnetic cylinder 3, a separation box, a separation plate 7, a frame 4 and a magnetic system adjustment device 9.

[0025] The basic working principle of the dry magnetic separator is: the transmission component 8 drives the magnetic drum 3 to rotate, and the material is directly fed into the upper magnetic field area of ​​the magnetic drum 3 through the feed port 1. The magnetic particles and non-magnetic particles are subjected to different magnetic forces. Under the rotation of the magnetic drum 3, the magnetic particles and non-magnetic particles (or extremely weak magnetic particles) produce different movement trajectories. The magnetic particles are adsorbed on the magnetic drum 3 or deviated toward the direction of the magnetic drum 3, and finally enter the magnetic mineral receiving bucket; and the extremely weak magnetic or non-magnetic particles are thrown into the non-magnetic product collection box under the action of centrifugal force, gravity, etc. due to the weak magnetic field force, thereby completing the material sorting process.

[0026] like Figure 3 As shown, the utility model provides an intelligent sorting dry magnetic separator, including: a main control module, an index monitoring module, a state monitoring module, a feedback adjustment module and a human-computer interaction module, wherein the index monitoring module, the state monitoring module, the feedback adjustment module and the human-computer interaction module are electrically connected to the main control module respectively. The intelligent sorting dry magnetic separator also includes a power supply for supplying power to the main control module.

[0027] The indicator monitoring module includes an automatic grade analyzer and a production monitor. The automatic grade analyzer is used to detect the grade of the ore on the conveyor belt of the dry magnetic separator, the concentrate and the tailings, and feed back the ore grade information to the main control module. The production monitor is used to monitor the production of the ore on the conveyor belt of the dry magnetic separator, the concentrate and the tailings, and feed back the information to the main control module.

[0028] The automatic grade analyzer adopts the LIBS automatic grade analyzer. Through the LIBS automatic grade analyzer, the grade of the ore on the conveyor belt of the dry magnetic separator, the concentrate and the tailings is detected, and the ore grade information is fed back to the main control module.

[0029] The production monitor uses a belt scale to monitor the production of ore on the conveyor belts of the dry magnetic separator's raw ore, concentrate, and tailings, and feeds back to the main control module.

[0030] The condition monitoring module includes a temperature-vibration integrated measuring instrument, which is used to detect the temperature and vibration of the dry magnetic separator bearing seat and the main shaft near the bearing, and feed back to the main control module.

[0031] The main control module is mainly for data storage and data processing. It is the core part of the whole system and can upload data to the cloud. It adjusts the equipment parameters through the optimization algorithm so that the sorting index is within the target range, effectively improving the working efficiency of the dry magnetic separator. The main control module receives the detection data of each sensor by PLC, and compares it with the threshold parameters such as grade and output set in advance. According to a certain control strategy (such as if the tailings grade is higher than the set threshold upper limit, the speed of the magnetic drum 3 is reduced so that the tailings grade detected again is within the set threshold range, and the actual tailings yield is also within the set threshold range.) The speed of the magnetic drum 3 is controlled to achieve the purpose of real-time monitoring and control of production indicators and equipment operation status.

[0032] The human-computer interaction module includes a sorting index target data input module and a display module. The display module includes a real-time sorting index display module and a bearing temperature data display module.

[0033] The feedback regulation module is used to adjust the magnetic drum speed, the ore separation plate position and the automatic lubrication parameters.

[0034] The control strategy is:

[0035] 1) When the tailings grade is greater than the set upper threshold, reduce the rotation speed of the magnetic drum 3 or increase the gap between the separation plate 7 and the magnetic drum 3, or combine the two, so that the tailings grade is less than the set upper threshold and the tailings yield is greater than the set lower threshold.

[0036] 2) When the tailings yield is less than the set lower threshold (and the tailings grade is less than the set upper threshold), increase the rotation speed of the magnetic drum 3 or reduce the gap between the separation plate 7 and the magnetic drum 3, or combine the two, so that the tailings yield is greater than the set lower threshold, and the tailings grade is maintained below the set upper threshold.

[0037] 3) When the bearing temperature of the dry magnetic separator is too high or the vibration of the bearing increases, increase the lubrication frequency and lubrication time of the automatic lubrication pump to ensure that the bearing temperature and vibration are within the allowable range. If the excessive bearing temperature or vibration cannot be eliminated, remind the control system to alarm and repair the equipment.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
