Description

Technical Field

[0001] This utility model relates to the technical field of impurity separation devices, and specifically discloses an automatic metal impurity separation device in the crushing process of metal mines. Background Technology

[0002] In the process of metal mining, before the raw ore enters the crusher for crushing, it is usually mixed with unexpected metal impurities such as broken drill bits, shovel teeth, and worn liners. The hardness and strength of these impurities are much higher than that of the ore. If they enter the core crushing equipment such as jaw crushers and cone crushers along with the material, they are very likely to cause equipment jamming, overload operation, or even fracture damage to core components such as moving cones and liners. The resulting unplanned downtime not only causes huge maintenance costs, but also directly affects the continuity of mine production and economic benefits. Therefore, setting up an efficient and reliable metal impurity separation process at the front end of the crushing process is of vital importance to ensuring the stable operation of the entire crushing system and reducing maintenance costs.

[0003] Currently, most methods for addressing this issue involve manual sorting, which is not only inefficient and labor-intensive, but also poses certain safety risks when dealing with large quantities of materials of varying sizes, as the sorting effect is difficult to guarantee. Utility Model Content

[0018] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0019] Example 1 like Figure 1-10 As shown, the automatic metal impurity separation device in the metal mine crushing process includes a support 1. A feeding frame 2 and a guide frame 3 are fixedly installed on both sides of the top of the support 1. A conveyor belt 4 is rotatably installed between the side of the guide frame 3 near the feeding frame 2 and the top of the support 1. A motor 5 is fixedly installed on the top of the side wall of the support 1 in conjunction with the conveyor belt 4. The output shaft of the motor 5 and the side of the conveyor belt 4 near the support 1 are connected by a key. A trapdoor 6 is rotatably installed at the bottom of the guide frame 3, and the two ends of the trapdoor 6 pass through the side walls of both sides of the guide frame 3. Two sets of guide rods 7 are fixedly installed at the bottom of both sides of the guide frame 3 in conjunction with the two ends of the trapdoor 6. The two sets of guide rods 7 are slidably connected to the two ends of the trapdoor 6. Arc springs 8 are fixedly connected between the two ends of the trapdoor 6 and the two sets of guide rods 7. A detection mechanism is installed in the upper part of the inner cavity of the guide frame 3, and a triggering mechanism is installed on the guide frame 3.

[0020] The trapdoor 6 is rotatably connected to the guide frame 3 via a pivot, and damping is provided at the connection between the pivot and the guide frame 3.

[0021] With the above setup, the motor 5 is fixedly connected to the bracket 1 by bolts; the middle of the conveyor belt 4 protrudes slightly upwards; both sets of guide rods 7 are fixedly connected to the guide frame 3 by welding; when using this device, the motor 5 needs to be started first, the output shaft of the motor 5 starts to rotate, and drives the conveyor belt 4 to start running. At this time, the ore mixture containing metal impurities is put into the feeding frame 2, and the ore mixture falls onto the running conveyor belt 4 through the feeding frame 2. The motor 5 continuously provides power, and the conveyor belt 4 steadily transports the material into the guide frame 3.

[0022] The detection mechanism includes a support plate 9, a trigger plate 10, and several probe columns 11. The support plate 9 is fixedly installed at the middle of the top of the guide frame 3. The trigger plate 10 is slidably installed at the top of the support plate 9. The bottom end of the trigger plate 10 passes through the support plate 9 and is hinged to several probe columns 11. The probe columns 11 are made of strong permanent magnet material.

[0023] The triggering mechanism includes a counterweight 12, a locking block 13, a sliding rod 14, a wedge block 15, a pin 16, and a return spring 17. The counterweight 12 is slidably disposed on the side of the guide frame 3 away from the unloading frame 2. The locking block 13 is fixedly disposed on the top of the counterweight 12. The sliding rod 14 is slidably disposed on the top of the guide frame 3. The wedge block 15 is fixedly disposed on the side of the sliding rod 14 away from the locking block 13, and the wedge block 15 is slidably sleeved on the outer surface of the trigger plate 10. The pin 16 is fixedly disposed on the side of the sliding rod 14 close to the locking block 13, and the pin 16 is engaged in the locking block 13. A return spring 17 is fixedly connected between the pin 16 and the guide frame 3.

[0024] The triggering mechanism also includes two sets of first pulleys 18, two sets of second pulleys 19, two sets of pulley groups 20, and two sets of steel ropes 21. The two sets of first pulleys 18 are respectively fixedly installed on both sides of the top of the guide frame 3 away from the material feeding frame 2. The two sets of second pulleys 19 are fixedly installed on both sides of the middle of the guide frame 3 away from the material feeding frame 2, in conjunction with the two sets of first pulleys 18. The two sets of pulley groups 20 are respectively fixedly installed on the top of both sides of the guide frame 3. The two sets of steel ropes 21 are respectively sleeved on both sides of the top of the counterweight 12, and the two sets of steel ropes 21 are respectively wound around the outer surfaces of the two sets of first pulleys 18, the two sets of second pulleys 19, and the two sets of pulley groups 20. The ends of the two sets of steel ropes 21 away from the counterweight 12 are respectively fixedly connected to the two ends of the trapdoor 6.

[0025] The triggering mechanism also includes a collection frame 22, which is slidably disposed at the top of the bracket 1 in conjunction with the guide frame 3, and the collection frame 22 is located on the side of the guide frame 3 near the unloading frame 2.

[0026] With the above configuration, several probe columns 11 are evenly and spacedly hinged to the bottom end of the trigger plate 10 along the length of the support plate 9; the locking block 13 is fixedly connected to the counterweight 12 by welding; the wedge block 15 and the pin 16 are fixedly connected to the slide rod 14 by welding; the top of the wedge block 15 is provided with an inclined surface in conjunction with the trigger plate 10; the bottom end of the pin 16 is provided with an inclined surface, and the side of the locking block 13 near the pin 16 is provided with a slot in conjunction with the inclined surface of the pin 16, and the pin 16 is locked in the slot of the locking block 13; the top of the locking block 13 is provided with an inclined surface in conjunction with the inclined surface of the pin 16; the two sets of first pulleys 18, the two sets of second pulleys 19, and the two sets of pulley groups 20 are all fixedly connected to the guide frame 3 by welding.

[0027] After the ore mixture enters the guide frame 3, the material first comes into contact with the detection mechanism. When non-magnetic ordinary ore slides past the detection column 11, it will only cause a slight sway, which is not enough to trigger subsequent actions. However, when ferromagnetic metal impurities pass by, the detection column 11 made of strong permanent magnet material will generate a strong adsorption force to attract the metal impurities. When the metal impurities fall downwards, they will drive the detection column 11 to move downwards in sync, thereby causing the trigger plate 10 to make a significant downward displacement at the top of the support plate 9. The trigger plate 10 will push the wedge block 15, forcing the slide rod 14 to move away from the locking block 13, driving the pin 16 to move in sync, thereby causing the pin 16 to disengage from the locking block 13 and release the locking block 13 from its constraint. The reset spring 17 is compressed in this process, and at this time the counterweight 12 moves downwards rapidly due to its own weight.

[0028] A support rod 23 is fixedly installed at the top of the guide frame 3 near the material feeding frame 2. A bidirectional threaded rod 24 is rotatably installed on the side of the material feeding frame 2 near the guide frame 3 in coordination with the support rod 23. A turbine 25 is fixedly installed at one end of the bidirectional threaded rod 24. A worm gear 26 is rotatably installed on the side of the material feeding frame 2 near the guide frame 3 in coordination with the turbine 25. The worm gear 26 and the turbine 25 mesh with each other.

[0029] Both sides of the support rod 23 are slidably provided with baffles 27. The bottom ends of the two sets of baffles 27 are evenly and intermittently provided with several discharge holes. The two sets of baffles 27 are respectively threaded to both ends of the bidirectional threaded rod 24.

[0030] A guide frame 28 is fixedly installed between the guide frame 3 and the top of the support 1, near the side of the feeding frame 2 and the top of the support 1, in conjunction with the conveyor belt 4. The guide frame 28 is located below the conveyor belt 4, and the inner wall of the guide frame 28 is coated with a smooth coating. A sliding frame 29 is slidably installed in the middle of the bottom end of the guide frame 28.

[0031] With the above configuration, the support rod 23 is fixedly connected to the guide frame 3 by welding; the turbine 25 is fixedly connected to the bidirectional threaded rod 24 by welding; the diversion frame 28 is fixedly connected to the bracket 1 and the guide frame 3 by welding; during the conveying of ore, a small amount of fine material or dust will fall from the conveyor belt 4 into the diversion frame 28 and eventually collect in the sliding frame 29; when the user needs to adjust the size of the separated material, the operator rotates the worm gear 26, which drives the turbine 25 meshing with it to rotate, and the turbine 25 drives the bidirectional threaded rod 24 to rotate, and the baffle 27 moves in opposite directions, thereby adjusting the gap between the baffle 27 and the conveyor belt 4.

[0032] Both sides of the lower part of the guide frame 3 are fixedly equipped with buffer pads 30 to cooperate with the trapdoor 6.

[0033] With the above setup, the buffer pad 30 is fixedly connected to the guide frame 3 by welding. When the counterweight 12 moves rapidly downward due to its own weight, the steel rope 21 applies a strong lifting force to the trapdoor 6. Under the traction of the steel rope 21, the trapdoor 6 rotates rapidly clockwise around the pivot, tilting to the side of the material frame 2, and compresses the arc spring 8. At this time, the metal impurities fall downward due to their own weight and gravity, and break away from the adsorption of the detection column 11, and then fall onto the trapdoor 6. Due to the tilt of the trapdoor 6, the metal impurities fall into the collection frame 22. The buffer pad 30 can effectively absorb the impact when the trapdoor 6 is opened to the maximum angle, reduce noise and protect the structure.

[0034] After the metal impurities are separated, the hammer 12 falls to the bottom, and its tension on the steel rope 21 disappears. At this time, the compressed arc spring 8 begins to release its elastic potential energy, driving the trapdoor 6 to reset. During the reset process of the trapdoor 6, the damping will slow down the reset speed of the trapdoor 6, ensuring that the metal impurities have enough time to pass through the trapdoor 6. Then, through the reverse transmission of the steel rope 21 and the pulley block 20, the hammer 12 is slowly raised back to the initial height. When the locking block 13 at the top of the hammer 12 moves upward past the pin 16, it can push the pin 16 to move to the side of the lower material frame 2, while compressing the reset spring 17. When the hammer 12 continues to move upward a certain distance, the reset spring 17 releases its elastic potential energy, pushing the pin 16 into the slot of the locking block 13, re-locking the locking block 13, and resetting the entire triggering mechanism to the initial state. At the same time, the normal ore that has not been separated continues to enter the subsequent process along the channel of the guide frame 3 after the trapdoor 6 is reset.
