Description

Metal sorting system

Technical Field

The present invention relates to the technical field of magnetic sorting, and in particular to a metal sorting system.

Background technique

As we all know, magnetic sorting machine is a machine that uses the principle of magnetism to sort materials. The working principle of magnetic sorting machine is as follows: materials enter the sorting machine system. The materials can be magnetic materials or materials with magnetic materials. The control system sends a signal to the corresponding electromagnet according to the pre-set classification conditions. When the signal is sent to the electromagnet, the electromagnet will generate a magnetic field. If the material is magnetic, it will be attracted to the position of the electromagnet that is attracted to its magnetism for further processing or classification; magnetic sorting machines are mostly used in recycling stations, production lines and many other occasions to improve the efficiency of material sorting.

For example, a Chinese patent discloses a metal waste conveying and sorting device (publication (announcement) number CN218078371U), which includes a vibrating material guide slope, a diversion discharge slope, a magnetic plate and a diversion gate; the vibrating material guide slope is suspended, and the metal waste is placed on the vibrating material guide slope from the high end and slides down from high to low; the magnetic plate is arranged at the bottom of the vibrating material guide slope, which is used to magnetically absorb the magnetic metal waste on the vibrating material guide slope; the diversion discharge slope is connected to the low end of the vibrating material guide slope, and the diversion gate is arranged at the feeding position of the diversion discharge slope, and the feeding position of the diversion discharge slope has a magnetic metal waste inlet and a non-magnetic metal waste inlet, and the magnetic metal waste inlet and the non-magnetic metal waste inlet are alternately opened and closed through the diversion gate to divert and discharge the magnetic metal waste and the non-magnetic metal waste; it can realize the sorting of magnetic metal waste and non-magnetic metal waste in metal waste, and has the advantages of good sorting effect and high efficiency.

However, when the inventor implemented this device, he found the following defects: during the process of sorting metal objects in the material, due to the concentrated loading of the material, small particles of metal objects are buried in the material, and the material is dispersed by vibration and inclined sliding so that the metal objects are adsorbed by the electromagnet on the vibrating material guide slope, but the adsorbed metal objects will block the normal movement of the material, and the material will also flush the adsorbed part of the metal objects away from the electromagnet, resulting in incomplete sorting of metal objects and materials, and the sorting effect of metal objects needs to be further improved; in the working state, the entire vibrating material guide slope is in a vibrating state, which will produce a lot of noise, and the equipment consumes a lot of energy, and has certain usage defects.

The conveyor belt 4 is set in an inclined manner, which can make the material form a certain sliding effect in the vibration process, avoid the material from moving too fast, and make the material have sufficient dispersion time on the conveyor belt 4, so as to ensure that the material is evenly dispersed on the conveyor belt 4, so as to expose the metal objects in the material, and provide guarantee for the subsequent magnetic suction sorting mechanism to sort the metal objects.

Specifically, the frame 1 is equipped with an elastic compensation mechanism for compensating the slack of the conveyor belt 4, and the elastic compensation mechanism includes elastic tension members 13 symmetrically arranged on both sides of the frame 1, a bearing seat 14 and a tension compensation roller 15 installed on the elastic tension member 13, and the tension compensation roller 15 is rotatably installed between the two bearing seats 14, and the bearing seat 14 is elastically connected to the frame 1 through the elastic tension member 13; further, the elastic tension member 13 provides the tension compensation roller 15 with an elastic tension toward the side close to the conveyor belt 4; the elastic tension member 13 is preferably a tension spring and a telescopic guide Part, the tension spring is sleeved on the extended end of the telescopic guide part; the elastic tension member 13 can also be a tension spring or other equivalent member with elastic tension effect; the elastic tension member 13 applies elastic tension to the tension compensation roller 15, so that the conveyor belt 4 is always in an elastic relaxation state, thereby ensuring that the conveyor belt 4 is tightly fitted with the driving shaft 2 and the sleeve 6, avoiding relative sliding between the conveyor belt 4 and the driving shaft 2 or the sleeve 6, and the elastic compensation mechanism can adaptively compensate for the ups and downs of the conveyor belt 4 during the vibration process to ensure the normal transportation of materials by the conveyor belt 4.

Specifically, it also includes a metal detector 16 and a bulk metal separator. The metal detector 16 is installed on the frame 1 above the feeding end of the conveyor belt 4. The bulk metal separator includes a three-way shell 17, a screen plate 18 rotatably installed in the three-way shell 17, and a rotating drive member 19 for providing power for the rotation of the screen plate 18. The three-way shell 17 is provided with a vertically upward feeding channel 20, a vertically downward discharging channel 21, and a sorting channel 22 arranged downwardly. The feeding channel 20, the discharging channel 21 and the sorting channel 22 are connected to each other, and the screen plate 18 is connected to the feeding channel 2 0 and the connecting part between the discharge channel 21 and the connecting part between the feed channel 20 and the sorting channel 22 fit together; further, the metal detector 16 is connected to the rotary drive member 19 through an external PLC or other control system signal; the rotary drive member 19 can drive the screen plate 18 to reciprocate 90 degrees; the rotary drive member 19 is preferably a drive plate and a drive cylinder fixedly connected to the screen plate 18, one end of the drive cylinder is hinged to the three-way housing 17, and the other end of the drive cylinder is hinged to the drive plate; the rotary drive member 19 can also use a brake stepper motor or the like that has the effect of driving the screen plate 18 to rotate Equivalent to a rotary drive; more specifically, the detection sensitivity of the metal detector 16 can be adjusted, and the metal detector 16 only senses large pieces of metal on the conveyor belt 4; in the initial state, the sieve plate 18 is in a vertical state and blocks the connection between the sorting channel 22 and the feed channel 20. When large pieces of metal exist in the material, it is difficult for the magnetic suction sorting mechanism to absorb the large pieces of metal from the conveyor belt 4. After the metal detector 16 senses the large pieces of metal, the signal is transmitted to the rotary drive 19 via a control system such as a PLC, and the rotary drive 19 drives the sieve plate 18 to rotate The screen plate 18 is moved 90 degrees, and the screen plate 18 is in a horizontal state to block the connection between the feed channel 20 and the discharge channel 21, and the materials and large pieces of metal fall onto the screen plate 18. The screen holes on the screen plate 18 allow the materials to pass through, while the large pieces of metal are retained on the screen plate 18. Then, the rotating driving member 19 drives the screen plate 18 to reset, so that the large pieces of metal enter the sorting channel 22, thereby realizing the sorting of materials and large pieces of materials. The metal sorting system can not only adsorb and sort small particles of metal, but also screen and sort large pieces of metal that cannot be adsorbed, thereby effectively improving the sorting capacity.

Specifically, it also includes an elastic connecting member 23, the three-way shell 17 is hingedly mounted on the frame 1, and a vibration motor 24 is fixedly mounted on the three-way shell 17, one end of the elastic connecting member 23 is connected to a position on the three-way shell 17 away from the hinge between the three-way shell 17 and the frame 1, and the other end of the elastic connecting member 23 is connected to the frame 1; further, the elastic connecting member 23 is preferably a tension spring, one end of the tension spring is hinged to the three-way shell 17, and the other end of the tension spring is hinged to the frame 1; the elastic connecting member 23 can also adopt an elastic belt or other equivalent member with an elastic connection effect; when a large piece of metal falls onto the horizontally placed screen plate 18, by starting the vibration motor 24, under the action of the tension spring, the three-way shell 17 vibrates, thereby accelerating the screening of materials on the screen plate 18, so as to shorten the sorting time of large pieces of metal, reduce the excessive mixing of materials in large pieces of metal, and improve the sorting effect of large pieces of metal.

Specifically, a loading hopper 25 is installed above the loading end of the frame 1 near the conveyor belt 4, and a plurality of spreading chains 26 are installed at the discharge port of the loading hopper 25; further, the discharge port of the loading hopper 25 is rectangular, and the discharge port spans above the loading end of the conveyor belt 4; the material can be loaded to the loading end of the conveyor belt 4 through the loading hopper 25, and the discharge port of the loading hopper 25 is rectangular, and the material is dispersed and falls onto the conveyor belt 4 through the rectangular discharge port, and in the process of the conveyor belt 4 driving the material to move, the spreading chain 26 further spreads the material, so that the material is evenly spread on the conveyor belt 4, and the spreading chain 26 can move synchronously with the conveyor belt 4 during the fluctuation of the conveyor belt 4, and will not cause excessive interference to the vibration of the conveyor belt 4, so as to ensure the fluctuation effect of the conveyor belt 4.

Specifically, a mesh cage 27 is detachably installed at the discharge port of the sorting channel 22 on the three-way shell 17; further, the mesh cage 27 is detachably connected to the discharge port of the sorting channel 22 by bolts or quick-release locking parts; the large pieces of metal separated by the sorting channel 22 enter the mesh cage 27, and the doped materials leak out at the mesh cage 27. When the large pieces of metal are sorted to a certain amount, the large pieces of metal in the mesh cage 27 can be processed collectively.

Specifically, a blocking frame 28 located above the conveyor belt 4 is installed on the frame 1, and a flexible blocking member 29 in close contact with the conveyor belt 4 is provided at the bottom of the blocking frame 28; the blocking frame 28 can reduce the material from falling from the edge of the conveyor belt 4, and the flexible blocking member 29 can achieve flexible contact between the blocking frame 28 and the conveyor belt 4. While the flexible blocking member 29 plays a blocking and limiting role on the material, it can avoid excessive interference with the fluctuation of the conveyor belt 4. The flexible blocking member 29 can adopt a soft brush or a rubber strip, etc.

Specifically, the metal detector 16 is equipped with an audible and visual alarm 30; further, the audible and visual alarm 30 is connected to the metal detector 16 via external PLC and other control system signals; when the metal detector 16 detects a large piece of metal, the signal can be transmitted to the audible and visual alarm 30 via the external PLC and other control systems. After the audible and visual alarm 30 is activated, it can remind the operator that a large piece of metal has passed by the conveyor belt 4, and the operator can discover and deal with it in time.

When in use, the material is put into the upper hopper 25, and the material is dispersed and falls onto the conveyor belt 4 through the rectangular discharge port on the upper hopper 25. When the conveyor belt 4 drives the material to move, the spreading chain 26 further spreads the material so that the material is evenly spread on the conveyor belt 4. The driving motor 3 drives the driving shaft 2 to rotate, thereby moving the conveyor belt 4. During the movement of the conveyor belt 4, the sleeve 6 on the fixed shaft 5 is driven to rotate. During the rotation of the sleeve 6, the ball 9 enters the sleeve 6, and the spring 8 is in a compressed state. When the conical hole 10 on the sleeve 6 is aligned with the ball 9, the spring 8 is reset, and the ball 9 leaks out from the conical hole 10. The ball 9 forms an instantaneous shaking impact force on the conveyor belt 4 in a direction perpendicular to the traveling direction of the conveyor belt 4, and a vibration shock wave is formed on the conveyor belt 4. The shock wave is transmitted along the conveying direction of the conveyor belt 4, and the material on the conveyor belt 4 is gradually vibrated and separated under the action of the vibration shock wave. The material is evenly dispersed during transportation, so that the metal objects in the material are exposed. When the metal objects reach the belt When the metal material is below the conveyor belt 11, the metal material is attracted to the bottom of the belt conveyor 11 under the suction of the magnetic suction component 12, and the belt conveyor 11 is started. The belt conveyor 11 moves the attracted metal material to the side away from the conveyor belt 4, so as to realize the sorting of small metal objects in the material. When there are large metal objects in the material, it is difficult for the magnetic suction sorting mechanism to absorb the large metal objects from the conveyor belt 4. The metal detector 16 senses the large metal and transmits the signal to the rotating control system through the PLC and other control systems. At the driving member 19, the rotating driving member 19 drives the sieve plate 18 to rotate 90 degrees. The sieve plate 18 is in a horizontal state to block the connection between the feed channel 20 and the discharge channel 21, and the material and large pieces of metal fall onto the sieve plate 18. The sieve holes on the sieve plate 18 allow the material to pass through, while the large pieces of metal are retained on the sieve plate 18. Then, the rotating driving member 19 drives the sieve plate 18 to reset, so that the large pieces of metal enter the sorting channel 22 and fall into the mesh cage 27, thereby realizing the sorting and processing of large pieces of metal in the material.
