The structure of the metal object identifying and sorting device 2 is shown in fig. 2 and comprises a raw coal distributor and three conveying belts. The raw coal distributor comprises a distributor frame 4 shown in fig. 3, and the upper end of the distributor frame 4 is of an open structure and used for receiving coal materials conveyed by the conveying device 1. In order to realize coal separation, three packing augers, namely a first packing auger 5, a second packing auger 6 and a third packing auger 7 are arranged in the distributor frame body 4, each packing auger is driven by an independent packing auger driving motor 14, and correspondingly, mounting holes for mounting the packing augers are formed in the front vertical wall and the rear vertical wall of the distributor frame body 4.
The rear ends of the three augers penetrate out of the mounting holes in the vertical wall on the rear side of the distributor frame body, the augers rotate to output the coal in the distributor frame body 4 through the three mounting holes in the vertical wall on the rear side of the distributor frame body, and the three mounting holes form three outlets 17 of the raw coal distributor. Because each auger is driven by an independent auger driving motor 14, the start and stop of each auger can be independently controlled, and the coal outlet at the corresponding outlet is controlled. In this embodiment, the auger drive motor is a servo motor.
Three conveyor belts are arranged corresponding to the three outlets 17 and used for receiving and conveying the coal material output from the corresponding outlets 17, and each conveyor belt moves forwards to convey the coal material backwards to the coal crusher 3. Specifically, the three conveyer belts are a first conveyer belt 8 corresponding to the first auger 5, a second conveyer belt 9 corresponding to the second auger 6, and a third conveyer belt 10 corresponding to the third auger 7. Each conveying belt is driven by an independent conveying belt driving motor, three relatively independent coal conveying branches are formed in the metal object identification and sorting device, and the motion state of each conveying belt can be controlled by controlling the rotation direction of each conveying belt driving motor. In this embodiment, the conveyor belt driving motor is a servo motor.
In order to detect metal objects in the coal materials conveyed by the conveyor belts, metal detectors are respectively arranged above the conveyor belts, wherein a first metal sensor 11 is arranged corresponding to the first conveyor belt 8, a second metal sensor 12 is arranged corresponding to the second conveyor belt 9, and a third metal sensor 13 is arranged corresponding to the third conveyor belt 10.
Furthermore, in order to sort out the metal objects in time after the metal detector detects the metal objects, the metal object identifying and sorting device 2 is further provided with a control system, the metal detector can feed back signals to the control system after detecting the metal objects, and meanwhile, the control system is in control connection with the auger driving motors and the conveyer belt driving motors so as to control the rotating speed of the augers and the motion state of the conveyer belts. In this embodiment, the computer controls the auger driving motors 14 and the conveyor belt driving motor through a series of instructions.
Taking the first metal detector 11 as an example, when the first metal detector 11 detects metal substances mixed in the coal conveyed by the first conveyor belt 8, the first metal detector 11 feeds back a detection signal to the computer, and the computer receives the detection signal and then sends three instructions at almost the same time: firstly, a conveyor belt driving motor corresponding to the first conveyor belt 8 is controlled to rotate reversely to drive the first conveyor belt 11 to move reversely for a set distance so as to unload the coal mixed with the metal objects from the front end of the first conveyor belt, and the size of the distance for the reverse movement of the first conveyor belt 11 is determined according to the distance between the first metal detector 11 and the front end of the first conveyor belt 11, so that the coal mixed with the metal objects can be unloaded after the first conveyor belt moves reversely for the set distance; secondly, the first packing auger 5 is controlled to stop rotating so as to suspend outputting coal from the corresponding outlet 17; and thirdly, the other augers in the raw coal distributor are controlled to increase the conveying of the coal material at a properly increased rotating speed so as to ensure the coal material supply of the coal crusher 3. When the coal material mixed with the metal material is discharged, the control system controls each part to quickly recover to normal work.
In other embodiments, the second and third packing augers increase the rotating speed to increase the output of the coal, and simultaneously, the moving speeds of the second and third conveying belts can be increased, so that the conveying speed of the conveying belts is matched with the coal outlet speed of the corresponding outlet. Of course, when the first conveying belt moves reversely to discharge the coal, if the coal supply of the coal crusher can be ensured only by increasing the moving speed of one auger and the corresponding conveying belt, the moving speed of one auger and the corresponding conveying belt can be increased. Even under the premise of low requirement on the coal supply stability, the movement speed of the other augers and the conveyer belt can not be increased. For the control system, in other embodiments, each metal detector and the driving motor can also be in control connection with a single chip microcomputer or a PLC controller.
Further, in order to collect the coal removed by the reverse movement of the conveyor belt, in this embodiment, the metal object identifying and sorting device 2 further includes a temporary storage device disposed at a lower side of the front end of the conveyor belt for collecting the coal discharged by the reverse movement of the conveyor belt. As shown in fig. 2, the temporary storage device includes a receiving hopper 15 and a collecting bin 16, wherein the receiving hopper 15 is used for receiving and guiding the coal to flow to the collecting bin 16, so as to prevent the coal from scattering to the ground, and facilitate the worker to pick out the metal objects and then send the coal to the coal pulverizer 3.
It should be noted that, in combination with the amount of the metal substances mixed in the actual raw coal, the probability of the metal substances appearing on the three conveyor belts at the same time is almost zero, so that when a certain conveyor belt needs to move in the reverse direction to discharge the coal material mixed with the metal substances, other conveyor belts can still continue to convey the coal material, and the stable coal conveying efficiency of the conveying system can be ensured. In addition, the probability that metal objects appear on the two conveying belts simultaneously is very small, so that on the premise that the conveying capacity meets the requirement, only two conveying belts can be arranged for reducing the production cost, and correspondingly, the packing augers only need to be arranged in two. Of course, four or more conveyor belts may be provided to increase the safety factor and increase the conveying capacity of the coal conveying system.
The utility model discloses middlings conveying system's embodiment 2, different from embodiment 1 is that, in embodiment 1, be provided with the auger in metal thing discernment and sorting device's the raw coal distributor, whether control system controls corresponding export through opening of control auger and exports the coal charge.
