Description

Technical Field

[0001] This utility model relates to the field of ore processing technology, specifically to an ore raw material sorting device. Background Technology

[0002] Ore sorting is a process that, based on the physical and chemical properties of different minerals in an ore, involves crushing and grinding the ore, and then using methods such as gravity separation, flotation, and magnetic separation to separate useful minerals from gangue minerals, and to separate various associated (symbiotic) useful minerals as much as possible, removing or reducing harmful impurities in order to obtain the desired raw materials. Ore sorting requires the crushing of the raw ore.

[0003] Currently, when using magnetic separation to separate ores, the crushed ore needs to be transported into the magnetic separation equipment, and the differences in magnetic properties among various minerals are used to separate them in a magnetic field. However, some incompletely crushed ores have a certain weight, and when the magnetic attraction is insufficient to counteract the weight of the ore, they cannot be attracted, resulting in the incompletely crushed ore not being separated. This leads to a waste of useful mineral resources and a decline in the overall efficiency of the mineral processing process. Therefore, it is urgent to design an ore raw material separation device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6In this embodiment of the present invention, an ore raw material sorting device includes a first support frame 1. A first belt conveyor 4 and a second belt conveyor 2 are respectively arranged on the top two sides of the first support frame 1. Side plates 13 are installed on the top two sides of the first belt conveyor 4 and one end two sides of the second belt conveyor 2. A third belt conveyor 12 is installed on the top of the two side plates 13, and a disk 16 is installed on the inner wall of the third belt conveyor 12. A second support frame 10 is installed on one end of the top of the first belt conveyor 4, and a crusher 11 is installed on the top of the second support frame 10. The first belt conveyor 4, the second belt conveyor 2, and the third belt conveyor 12 are provided with the same transmission assembly 14. 14 includes a connecting shaft 1402 rotatably mounted on one side of the third belt conveyor 12. A transmission gear 1403 is installed on one side of the outer wall of the connecting shaft 1402 and on the transmission ends of both the first belt conveyor 4 and the second belt conveyor 2. The three transmission gears 1403 are meshed with the same transmission toothed belt 1404. A gear disc 1401 is installed on the transmission end of the third belt conveyor 12 and on the other side of the outer wall of the connecting shaft 1402, and the two gear discs 1401 mesh with each other. A first motor 9 for driving the first belt conveyor 4 is installed on one side. A guide frame 3 is installed at the bottom of the two side plates 13 and at the bottom of the first belt conveyor 4, and one end of the guide frame 3 is connected to the first belt conveyor... A screening box 5 is installed at one bottom end of the machine 4. An arc-shaped filter screen 17 is fixedly installed on the inner wall of the screening box 5, and the arc-shaped filter screen 17 is designed to be inclined. A return component 7 is provided on one side of the screening box 5. The return component 7 includes a mounting base 8 installed on one side of the screening box 5, and a feeding cylinder 701 is fixedly installed on one side of the mounting base 8. An inclined guide pipe 702 is fixedly installed on the bottom side of one side of the feeding cylinder 701 and the side of the screening box 5. A return pipe 704 is fixed on the top side of one side of the feeding cylinder 701. The tail end of the return pipe 704 is located above the feed inlet of the crusher 11. A drive shaft 705 is rotatably installed on the inner wall of the feeding cylinder 701, and a part that fits against the inner wall of the feeding cylinder 701 is installed on the drive shaft 705. The screw conveyor blades 706 and the top of the feeding cylinder 701 are fixedly installed with a second motor 703 for driving the drive shaft 705 to rotate. The bottom of the return assembly 7 is provided with a vibration assembly 6 inserted into the screening box 5. The ore raw material crushed by the crusher 11 falls onto the first belt conveyor 4 and is transported to the designated position. The magnetic disk 16 attracts the magnetic ore particles and adsorbs them. As the third belt conveyor 12 operates, the magnetic ore particles are transported to one side and separated from other non-magnetic ore particles. When the magnetic ore moves away from the disk 16, the magnetism disappears and it falls along the discharge frame 15 onto the second belt conveyor 2 for transport, thus realizing magnetic sorting.

[0027] Some heavier ore raw materials and non-magnetic ores that are not adsorbed by the disk 16 fall into the feed box 3 and then enter the screening box 5. Under the action of gravity, the ore raw materials slide down the arc-shaped filter screen 17. During the slide, particles smaller than the filter screen aperture fall to the bottom of the screening box 5, while particles larger than the filter screen aperture continue to slide down, thus achieving particle size screening. The second motor 703 in the return assembly 7 drives the drive shaft 705 and the auger blades 706 to rotate, which can send the screened heavier ore back to the feed port of the crusher 11, thus achieving ore recycling.

[0028] Furthermore, when the reflux assembly 7 is working, it will drive the turntable 601 inside the vibration assembly 6 to rotate, and in conjunction with the traction rod 602, drive the movable frame 604 and the impact rod 610 to reciprocate. Thus, the impact of the impact rod 610 and the protective pad 609 on the force seat 603 will create vibration on the arc-shaped filter screen 17, preventing ore particles from clogging the filter screen and enhancing the screening effect.

[0029] Specifically, a material leakage frame 15 is installed on one side of the two side plates 13 and one side of the bottom of the third belt conveyor 12, and one side of the material leakage frame 15 and one side of the side plate 13 are both designed to be inclined to prevent material leakage.

[0030] Specifically, the vibration assembly 6 includes a guide opening at the bottom of one side of the screening box 5, and a movable frame 604 is inserted into the inner wall of the guide opening. A turntable 601 is mounted on the bottom of the drive shaft 705. A traction rod 602 is rotatably connected to the bottom side of the turntable 601 and the top side of the movable frame 604. A fixed cylinder 606 is fixed to the top of the movable frame 604, and an impact rod 610 is inserted into the inner wall of the fixed cylinder 606. A spring 608 is installed at one end of the impact rod 610 and the inner wall of the fixed cylinder 606, and a protective pad 609 is installed at the other end of the impact rod 610. The bottom of the arc-shaped filter screen 17... A force-bearing seat 603 is installed on one side, and the position of the force-bearing seat 603 corresponds to the position of the impact rod 610. A guide hole 607 is opened on one side of the movable frame 604, and a guide rod 605 passing through the guide hole 607 is installed on the inner wall of the screening box 5, so that the vibration component 6 works synchronously when the return component 7 is working, driving the turntable 601 to rotate. In conjunction with the traction rod 602, the movable frame 604 and the impact rod 610 reciprocate, thereby impacting the protective pad 609 through the impact rod 610, forming vibration on the arc-shaped filter screen 17, preventing ore particles from clogging the filter screen and enhancing the screening effect.

[0031] The working principle of this utility model is as follows: the first motor 9 drives the first belt conveyor 4 to run, and with the transmission action of the transmission component 14, the second belt conveyor 2 and the third belt conveyor 12 rotate synchronously, and the disk 16 is powered on.

[0032] Next, the ore raw material crushed by the crusher 11 falls onto the first belt conveyor 4, which transports the ore raw material to the designated position. The magnetic disk 16 attracts the magnetic ore particles and adsorbs them. As the third belt conveyor 12 operates, the magnetic ore particles are transported to one side and separated from other non-magnetic ore particles. When the magnetic ore moves away from the disk 16, the magnetism disappears, and it falls along the discharge frame 15 onto the second belt conveyor 2 for transport, thus achieving magnetic sorting.

[0033] Some heavier ore raw materials and non-magnetic ores that are not adsorbed by the disk 16 fall into the feed box 3 and then enter the screening box 5. Under the action of gravity, the ore raw materials slide down the arc-shaped filter screen 17. During the slide, particles smaller than the filter screen aperture fall to the bottom of the screening box 5, while particles larger than the filter screen aperture continue to slide down, thus achieving particle size screening. The second motor 703 in the return assembly 7 drives the drive shaft 705 and the auger blades 706 to rotate, which can send the screened heavier ore back to the feed port of the crusher 11, thus achieving ore recycling.

[0034] Furthermore, when the reflux assembly 7 is working, it will drive the turntable 601 inside the vibration assembly 6 to rotate, and in conjunction with the traction rod 602, drive the movable frame 604 and the impact rod 610 to reciprocate. Thus, the impact of the impact rod 610 and the protective pad 609 on the force seat 603 will create vibration on the arc-shaped filter screen 17, preventing ore particles from clogging the filter screen and enhancing the screening effect.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
