Description

Technical Field

[0001] This utility model relates to the field of mineral processing machine technology, and in particular to a polymetallic ore processing machine. Background Technology

[0002] Polymetallic ores typically contain a variety of valuable metallic components, such as copper, lead, zinc, gold, and silver; a mineral processing machine is a device that separates and screens magnetic metallic minerals from gravel in fine ores.

[0003] Existing technologies, such as patent CN204564312U, disclose a multi-metal ore beneficiation machine. This patent employs a frame, an outer casing and a motor mounted on the frame, and an inner casing housed within the outer casing. A feed pipe is located above the inner casing, and a backwash water pipe is located at the bottom. The bottom of the outer casing has a concentrate outlet and a tailings outlet. A pressure regulating valve is installed on the backwash water pipe. A gearbox is connected to the shaft end of the motor, and the output shaft of the gearbox is driven by the rotating shaft of the inner casing. The tailings outlet is connected to a collection trough, and a slurry pump is installed within the collection trough. The outlet of the slurry pump is connected to the feed pipe via a slurry pipe. This utility model device solves the problem that existing beneficiation equipment has a relatively simple structure, allowing only one type of ore beneficiation and preventing the beneficiation of multiple metal ores.

[0004] In daily operation, during the separation of metal ores within polymetallic ores, the existing equipment has a relatively simple metal separation technology, making it difficult to quickly distinguish and separate metal ores with different magnetic properties within polymetallic ores, resulting in low equipment efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment struggles to differentiate and separate different magnetic metal ores within polymetallic ores, and to propose a polymetallic ore beneficiation machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polymetallic ore beneficiation machine, comprising a first mounting frame, a conveyor belt, a feed hopper, and a second mounting frame. The conveyor belt is rotatably disposed inside the first mounting frame, and the feed hopper is fixedly connected inside the second mounting frame. The discharge end of the feed hopper is disposed above one end of the conveyor belt. A magnetic attraction device is installed above the conveyor belt. The magnetic attraction device includes a connecting frame and a first belt. The connecting frame is disposed above the first mounting frame, and the first belt is rotatably connected inside the connecting frame. A second belt is also rotatably connected inside the connecting frame, and the second belt is disposed on one side of the first belt. A first magnetic plate is fixedly connected inside the connecting frame, and the first magnetic plate is attached to the inner bottom surface of the first belt. A second magnetic plate is connected inside the connecting frame, and the second magnetic plate is attached to the inner bottom surface of the second belt.

[0007] Furthermore, a controller is fixedly connected to the upper surface of the first and second magnetic plates, and a rotating shaft is rotatably connected to one end of the first and second belts. By setting the controller, the magnetic attraction of the first and second magnetic plates can be adjusted, reducing the difficulty in distinguishing and separating metal ores with different magnetic strengths in polymetallic ores when the equipment is running because the magnetic attraction of the first and second magnetic plates is the same.

[0008] Furthermore, a first motor is fixedly connected to one end of the rotating shaft, and the first motor is fixedly connected to one end of the connecting frame.

[0009] Furthermore, a first collection box is provided below the first belt near the shaft end, and a second collection box is provided below the second belt near the shaft.

[0010] Furthermore, a shaking device is provided inside the discharge end of the feed hopper. The shaking device includes a shaking plate and a diverting rod. The shaking plate is fixed to the bottom of the discharge end of the feed hopper, and the diverting rod is fixedly connected to the surface of the shaking plate. An installation arm is fixedly connected to the lower surface of the feed hopper, and a cam is rotatably connected inside the installation arm. One end of the cam is fixedly connected to a first rotating wheel, and a connecting arm is rotatably connected to the surface of the first rotating wheel. By setting the shaking plate, the material inside the discharge end of the feed hopper can be shaken evenly, reducing the accumulation of material in the middle of the conveyor belt and preventing the equipment from magnetically separating the accumulated ore.

[0011] Furthermore, a second rotating wheel is rotatably connected to the end of the connecting arm away from the first rotating wheel, and a second motor is fixedly connected to the side of the second rotating wheel away from the connecting arm.

[0012] Furthermore, a connecting seat is fixedly connected to the surface of the second motor, and the connecting seat is fixedly connected to the surface of the second mounting bracket.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up a magnetic attraction device, when the equipment separates polymetallic ores from the surface of the conveyor belt, the first motor is started to drive the shaft to rotate, which in turn drives the first belt and the second belt to rotate. The first magnetic plate and the second magnetic plate are respectively connected to the inner bottom surface of the first belt and the second belt. When the polymetallic ores pass under the magnetic attraction device through the conveyor belt, the controller controls the magnetism between the first magnetic plate and the second magnetic plate. The first magnetic plate has a weaker magnetism, which performs preliminary screening of the polymetallic ores, while the second magnetic plate has a stronger magnetism, which performs secondary screening of the metals inside the polymetallic ores. Metals with different magnetic intensities in the polymetallic ores are attracted to the belt by the first magnetic plate and the second magnetic plate and transported to the corresponding first collection box and second collection box as the belt rotates. Compared with the prior art, which requires multiple separation processes to extract different magnetic metals from the polymetallic ores, this magnetic attraction device can quickly classify and screen out magnetic metals in the polymetallic ores without multiple processes, reducing the working time of the equipment in extracting magnetic metals from the polymetallic ores, while improving the separation efficiency and purity of magnetic metals.

[0015] In this invention, by setting up a shaking device, when the equipment is feeding polymetallic ore, the second motor is started to drive the second rotating wheel to rotate. Through the connecting arm and the first rotating wheel, the cam is driven to rotate. When the cam rotates, it causes the shaking plate to shake, dispersing the polymetallic ore onto the surface of the conveyor belt. Compared with the existing equipment where the ore is not evenly dispersed and affects the mineral processing effect, this shaking device can evenly disperse the ore in the feed hopper onto the surface of the conveyor belt, providing a good foundation for subsequent mineral processing steps such as magnetic separation. It also reduces the accumulation of ore in the middle of the conveyor belt during feeding, which affects the mineral processing effect of the equipment, and improves the stability and efficiency of the equipment's mineral processing.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a polymetallic ore beneficiation machine, including a first mounting frame 1, a conveyor belt 2, a feed hopper 3, and a second mounting frame 4. The conveyor belt 2 is rotatably disposed inside the first mounting frame 1, and the feed hopper 3 is fixedly connected inside the second mounting frame 4. The discharge end of the feed hopper 3 is disposed above one end of the conveyor belt 2.

[0024] The specific settings and functions of the magnetic attraction device 5 and the shaking device 6 will be explained in detail below.

[0025] In this embodiment: A magnetic suction device 5 is installed above the conveyor belt 2. The magnetic suction device 5 includes a connecting frame 51 and a first belt 52. The connecting frame 51 is located above the first mounting frame 1. The first belt 52 is rotatably connected inside the connecting frame 51. A second belt 53 is also rotatably connected inside the connecting frame 51. The second belt 53 is located on one side of the first belt 52. A first magnetic plate 54 is fixedly connected inside the connecting frame 51. The first magnetic plate 54 is attached to the inner bottom surface of the first belt 52. A second magnetic plate 510 is connected inside the connecting frame 51. The second magnetic plate 510 is attached to the inner bottom surface of the second belt 53.

[0026] Specifically, a controller 55 is fixedly connected to the upper surface of the first magnetic plate 54 and the second magnetic plate 510, and a rotating shaft 57 is rotatably connected to one end of the first belt 52 and the second belt 53.

[0027] In this embodiment: by setting the controller 55, the magnetic attraction of the first magnetic plate 54 and the second magnetic plate 510 can be adjusted, reducing the situation where it is difficult to distinguish and separate metal ores with different magnetic strengths in polymetallic ores when the equipment is running, because the magnetic attraction of the first magnetic plate 54 and the second magnetic plate 510 is the same.

[0028] Specifically, a first motor 56 is fixedly connected to one end of the rotating shaft 57. The first motor 56 is fixedly connected to one end of the connecting frame 51. The first motor 56 drives the rotating shaft 57 to rotate the first belt 52 and the second belt 53 synchronously, so as to sort different metal ores inside the polymetallic mine synchronously.

[0029] Specifically, a first collection box 58 is provided below the end of the first belt 52 near the shaft 57, and a second collection box 59 is provided below the second belt 53 near the shaft 57. The first collection box 58 and the second collection box 59 collect different magnetic metal ores.

[0030] In this implementation scheme: a shaking device 6 is provided inside the discharge end of the feed hopper 3. The shaking device 6 includes a shaking plate 61 and a diverting rod 62. The shaking plate 61 is fixed to the bottom of the discharge end of the feed hopper 3. The diverting rod 62 is fixedly connected to the surface of the shaking plate 61. An installation arm 63 is fixedly connected to the lower surface of the feed hopper 3. A cam 64 is rotatably connected inside the installation arm 63. A first rotating wheel 65 is fixedly connected to one end of the cam 64. A connecting arm 67 is rotatably connected to the surface of the first rotating wheel 65. The material of the shaking plate 61 is a plastic material with good elasticity and a certain hardness, which can quickly deform and return to its original shape when subjected to force.

[0031] In this embodiment: by setting the shaking plate 61, the material inside the feeding end of the feed hopper 3 can be shaken evenly, reducing the accumulation of material in the middle of the conveyor belt 2, which makes it difficult for the equipment to magnetically separate the accumulated ore.

[0032] Specifically, a second rotating wheel 66 is rotatably connected to the end of the connecting arm 67 away from the first rotating wheel 65, and a second motor 68 is fixedly connected to the side of the second rotating wheel 66 away from the connecting arm 67.

[0033] Specifically, a connecting seat 69 is fixedly connected to the surface of the second motor 68. The connecting seat 69 is fixedly connected to the surface of the second mounting bracket 4. The second motor 68 drives the second rotating wheel 66 to rotate, and drives the cam 64 to rotate through the connecting arm 67 and the first rotating wheel 65. When the cam 64 rotates, it will cause the shaking plate 61 to shake.

[0034] Working principle: When the equipment separates polymetallic ore from the surface of conveyor belt 2, the first motor 56 is started to drive the rotating shaft 57 to rotate, which in turn drives the first belt 52 and the second belt 53 to rotate. The first magnetic plate 54 and the second magnetic plate 510 are respectively engaged with the inner bottom surfaces of the first belt 52 and the second belt 53. When the polymetallic ore passes under the magnetic attraction device 5 through the conveyor belt 2, the controller 55 controls the magnetism between the first magnetic plate 54 and the second magnetic plate 510. The first magnetic plate 54 has a weaker magnetism, which performs preliminary screening of the polymetallic ore, while the second magnetic plate 510 has a stronger magnetism, which attracts the gold inside the polymetallic ore. The process involves secondary screening. In polymetallic ores, metal ores with different magnetic intensities are adsorbed onto the belt by the first magnetic plate 54 and the second magnetic plate 510. As the belt rotates, they are transported to the corresponding first collection box 58 and second collection box 59. Compared with the prior art, which requires multiple separation processes to extract different magnetic metal ores from polymetallic ores, this magnetic adsorption device 5 can quickly classify and screen magnetic metal ores in polymetallic ores without multiple processing steps. This reduces the working time of the equipment in extracting magnetic metal ores from the inside of polymetallic ores, while improving the separation efficiency and purity of magnetic metal ores.

[0035] When the equipment is feeding polymetallic ore, the second motor 68 is started to drive the second rotor 66 to rotate. Through the connecting arm 67 and the first rotor 65, the cam 64 is driven to rotate. When the cam 64 rotates, the shaking plate 61 will shake to disperse the polymetallic ore onto the surface of the conveyor belt 2. Compared with the existing equipment where the ore is not evenly dispersed and affects the mineral processing effect, this shaking device 6 can evenly disperse the ore in the feed hopper 3 onto the surface of the conveyor belt, providing a good foundation for subsequent mineral processing steps such as magnetic separation. It reduces the accumulation of ore in the middle of the conveyor belt 2 during feeding, which affects the mineral processing effect of the equipment, and at the same time improves the stability and efficiency of the equipment's mineral processing.
