DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] like Figure 1-5 As shown, this embodiment proposes a magnetic separation device for ore concentration, including a frame 1, a lower box 2 is arranged in the middle of the top of the frame 1, an upper box 3 is rotatably mounted on one side of the lower box 2, and the upper box 3 can be rotated toward the lower box 2 to form a cavity, a crushing mechanism 4 is arranged inside the cavity for crushing the ore, and a magnetic separation mechanism 5 is arranged on one side of the lower box 2 for magnetic separation of the ore;

[0031] like Figure 2 and Figure 4 As shown, the crushing mechanism 4 includes a reduction motor 401, a rotating shaft 402, a crushing roller 403, a crushing hammer 404, a rotating base 405, a first pulley 406, a second pulley 407 and a connecting belt 408. The reduction motor 401 is fixedly arranged at the bottom cross bar of the frame 1, and the rotating shaft 402 is cooperatively installed at the output end of the reduction motor 401. The crushing roller 403 is located in a cavity formed by the upper box body 3 and the lower box body 2, and the two ends of the crushing roller 403 are rotatably installed with the side wall of the lower box body 2. The crushing hammer 404 is fixedly installed on the crushing roller 403, and the rotating base 405 is fixedly installed on both sides of the lower box body 2. The first pulley 406 is fixedly installed on the rotating shaft 402, and the second pulley 407 is fixedly installed on one end of the crushing roller 403. The connecting belt 408 is installed on the first pulley 406 and the second pulley 407, and the first pulley 406 and the second pulley 407 are connected to each other for transmission. When in use, the reduction motor 401 works, and after the ore enters the lower box body 2, it drives the rotating shaft 402 to rotate, and transmits the movement to the crushing roller 403 through the first pulley 406, the second pulley 407 and the connecting belt 408. Through the action of the crushing roller 403 and the crushing hammer 404, the incoming ore is simply crushed so that the ore can be completely separated from the ore.

[0032] like Figure 2 and Figure 4 As shown, the magnetic separation mechanism 5 includes a discharge port 501, a magnetic separation channel 502 and a coil 503. The discharge port 501 is opened at one side of the bottom of the lower box 2. One end of the magnetic separation channel 502 is fixedly installed at the discharge port 501. The coil 503 is evenly wound around the periphery of the magnetic separation channel 502. The crushed ore is discharged from the discharge port 501 of the lower box 2 and flows inside the magnetic separation channel 502. Since the end of the coil 503 is connected to an external power supply, the magnetic field strength can be changed by changing the size of the external current, thereby adapting to the separation of ores of different volumes.

[0033] The magnetic separation channel 502 is a metal cylinder, the magnetic separation channel 502 is connected with the lower box body 2, and the lower box body 2 is connected with the upper box body 3.

[0034] like Figure 2 As shown, a feed hopper 6 is installed on the top of the upper box body 3, and the feed hopper 6 is in a shape of being wide at the top and narrow at the bottom. Mineral materials are fed from the feed hopper 6, which is convenient for use.

[0035] like Figure 1 As shown, a collecting frame 7 is provided below the magnetic separation channel 502, and the collecting frame 7 is placed on a conveyor belt mechanism 10. The conveyor belt mechanism 10 drives the conveyor belt to move back and forth to realize that different types of collecting frames 7 are aligned with the discharge port. The number of collecting frames 7 is multiple groups, and they move automatically below the magnetic separation channel 502. Different collecting frames 7 store different types of ores.

[0036] like Figure 2 As shown, a connecting rod 8 is provided at one end of the magnetic separation channel 502, and the two ends of the connecting rod 8 are respectively hung on the edge of the lower box 2 and the outer end of the magnetic separation channel 502. The end of the magnetic separation channel 502 is connected to the lower box 2 to increase the strength of the magnetic separation channel 502.

[0037] like Figure 2 As shown, the diameter of the first pulley 406 is smaller than the diameter of the second pulley 407, and the connecting belt 408 adopts a V-belt drive. The diameter of the first pulley 406 is smaller than the diameter of the second pulley 407, which can reduce the rotation speed, and the V-belt drive can increase the friction between the connecting belt 408 and the first pulley 406 and the second pulley 407.

[0038] like Figure 2 As shown, a vibration motor 9 is fixedly installed at the bottom of the magnetic separation channel 502, and the vibration motor 9 is powered by external equipment. When the ore flows inside the magnetic separation channel 502, the vibration motor 9 works, driving the magnetic separation channel 502 to vibrate continuously, shaking up the ore and ore mixture inside, which is convenient for magnetic separation.

[0039] The reduction motor 401, the vibration motor 9 and the coil 503 are all electrically connected to the control panel through the controller.

[0040] Specifically, when the magnetic separation device for ore selection is working: the reduction motor 401 is working, and the ore is fed from the feed hopper 6. After the ore enters the lower box body 2, it drives the rotating shaft 402 to rotate, and the movement is transmitted to the crushing roller 403 through the first pulley 406, the second pulley 407 and the connecting belt 408. Through the action of the crushing roller 403 and the crushing hammer 404, the incoming ore is simply crushed, and the crushed ore is discharged from the discharge port 501 of the lower box body 2 and flows inside the magnetic separation channel 502. The vibration motor 9 is working, driving the magnetic separation channel 502 to vibrate continuously, shaking up the ore and ore mixture inside. Under the action of the magnetic field, the ore is adsorbed on the inner wall of the magnetic separation channel 502, and other substances flow to the collection frame 7 below along the magnetic separation channel 502. Then the collection frame 7 moves forward, the magnetic separation channel 502 is powered off, and the ore falls off from the inner wall of the magnetic separation channel 502 and falls into the subsequent collection frame 7.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
