Description

Technical Field

[0001] This invention relates to the field of waste incineration slag treatment technology, specifically to a comprehensive waste incineration slag treatment center and its treatment process. Background Technology

[0002] Waste incineration is a process in which waste is reduced in volume through appropriate thermal decomposition, combustion, and melting reactions at high temperatures, becoming residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities and post-incineration slag treatment facilities to prevent heavy metals, organic pollutants, etc., from being released back into the environment. The heat generated by waste incineration can be recovered to achieve the goal of waste resource utilization. The slag after waste incineration can also be reused after treatment. Existing slag treatment devices usually directly put the slag into a column magnetic separator for magnetic separation. After magnetic separation, it is then conveyed to a vibrating screen for screening. The screened particulate matter is transported to a brick factory for secondary use. However, when using existing magnetic separators to magnetically separate slag, the incinerated slag is prone to agglomeration, resulting in incomplete magnetic separation and affecting the subsequent screening quality. Therefore, we propose a comprehensive treatment center for post-incineration slag and its treatment process. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a comprehensive treatment center for slag after waste incineration and its treatment process, which can perform multi-stage separation of slag after waste incineration, so as to remove metal substances in the slag more thoroughly, and can also screen the slag to facilitate subsequent recycling and reuse of slag, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive treatment center for waste incineration slag and its treatment process, comprising an outer shell and a magnetic separation unit;

[0005] The outer shell has a hopper at its upper opening. Rollers are evenly connected to the gap at the upper end of the front and rear inner walls of the outer shell. The two vertically corresponding rollers are connected by belt drive. The front ends of the two lower rollers extend to the outside of the outer shell and have gears at their ends. The two gears mesh with each other. A drive motor is located on the rear side of the outer shell. The output shaft of the drive motor is fixedly connected to the rear end of the lower right roller. The two lower rollers are permanent magnet rollers. The inner center of the outer shell has symmetrical guide plates corresponding to the belt.

[0006] Magnetic separation unit: It is located inside the housing. The right side of the housing has a first discharge port that cooperates with the magnetic separation unit. The lower end of the housing is equipped with a third electric conveyor belt corresponding to the magnetic separation unit. The left end of the housing is equipped with a second discharge port corresponding to the third electric conveyor belt.

[0007] The outer casing is equipped with a controller on its front side. The input end of the controller is electrically connected to an external power source. The input ends of the third electric conveyor belt and the drive motor are both electrically connected to the output end of the controller. This allows for multi-stage separation of the slag after waste incineration, making the removal of metal substances from the slag more thorough. It also allows for sieving of the slag, facilitating subsequent recycling.

[0008] Furthermore, the magnetic separation unit includes a first electric conveyor belt, a second electric conveyor belt, and a strong magnetic plate. The first and second electric conveyor belts are both located at the center of the inner shell. The second electric conveyor belt is located above the first electric conveyor belt and is offset to the left and right from the first electric conveyor belt. The frame of the first electric conveyor belt is equipped with a strong magnetic plate. The second electric conveyor belt is positioned corresponding to the first discharge port. The third electric conveyor belt is located at the lower end of the first electric conveyor belt. The first electric conveyor belt is equipped with a vibration component. The input ends of the first and second electric conveyor belts are both electrically connected to the output end of the controller to facilitate the separation of magnetic metals in the slag.

[0009] Furthermore, the vibration assembly includes a vibrating plate, a first vibration motor, top columns, sliding sleeves, springs, and a mounting plate. The mounting plate is disposed inside the frame of the first electric conveyor belt. Sliding sleeves are evenly provided at the four corners of the upper surface of the mounting plate. Springs are provided on the inner bottom surface of each sliding sleeve. Top columns are slidably connected inside each sliding sleeve. The upper ends of the springs are fixedly connected to the bottom surfaces of the vertically corresponding top columns. The upper ends of the four top columns are fixedly connected to the bottom surface of the vibrating plate. The first vibration motor is provided on the bottom surface of the vibrating plate. The input end of the first vibration motor is electrically connected to the output end of the controller, so that the magnetic metals in the slag are separated more thoroughly.

[0010] Furthermore, magnets are uniformly arranged inside the transmission roller on the left side of the third electric conveyor belt, with adjacent magnets having opposite magnetic poles, which facilitates the separation of non-magnetic substances in the slag.

[0011] Furthermore, it also includes a sieve plate, the left end of which is rotatably connected to the lower end of the inner wall of the outer shell via a pin. The sieve plate is located at the lower end of the first electric conveyor belt. A second vibration motor is symmetrically arranged on the right side of the bottom surface of the sieve plate. A support assembly is symmetrically rotatably connected to the middle of the bottom surface of the sieve plate. The lower ends of the support assemblies are rotatably connected to the lower end of the inner wall of the outer shell. The input end of the second vibration motor is electrically connected to the output end of the controller to facilitate the screening of slag.

[0012] Furthermore, the support assembly includes a support rod, a support spring, and a support cylinder. The support cylinder is symmetrically and rotatably connected to the lower end of the inner wall of the outer shell. The support rod is slidably connected inside the support cylinder. The upper end of the support rod is rotatably connected to the bottom surface of the sieve plate. The upper and lower ends of the support rod are movably fitted with support springs. The support springs are located inside the support cylinder on the same side, providing elastic support for the sieve plate.

[0013] Furthermore, it also includes a material feeding unit, which is rotatably connected between the front and rear inner walls of the outer casing. The material feeding unit is located between the two belts and corresponds to the discharge port of the hopper, which can prevent slag from clumping.

[0014] Furthermore, the feeding unit includes a feeding frame, an inner feeding plate, an installation shaft, and an outer feeding plate. The feeding frame is rotatably connected between the front and rear inner walls of the outer casing. The feeding frame is located between the two belts and corresponds to the discharge port of the hopper. The outer feeding plate is symmetrically arranged in the middle of the feeding frame. The installation shaft is rotatably connected inside the feeding frame. The inner feeding plate is arranged in the middle of the installation shaft to facilitate the dispersing of slag.

[0015] Furthermore, the rear end of the mounting shaft extends to the outside of the material feeder. Both the rear end of the mounting shaft and the rear end of the material feeder are provided with end face gears. The rear side of the housing is provided with a feeding motor. The lower end of the output shaft of the feeding motor is provided with a gear. Both end face gears are meshed with the gear. The input end of the feeding motor is electrically connected to the output end of the controller to provide driving force for the rotation of the mounting shaft and the material feeder.

[0016] A treatment process for a comprehensive waste incineration slag treatment center includes the following steps:

[0017] Primary magnetic separation: After the waste is incinerated, the slag is fed into the interior of the outer shell through the hopper. At the same time, the drive motor drives the lower right roller to rotate, and the lower left roller rotates synchronously in the opposite direction through gears. Meanwhile, the two belts convey the slag in opposite directions. Since the two lower rollers are permanent magnet rollers, when the slag falls between the two lower rollers, the lighter magnetic substances in the slag can be adsorbed onto the surface of the belt. As the belt is conveyed, the magnetic substances fall to both sides of the guide plate, which facilitates the removal of the lighter magnetic metal substances in the slag.

[0018] Secondary magnetic separation: The magnetically separated slag falls onto the upper surface of the first electric conveyor belt. The first electric conveyor belt transports the slag to the right. At the same time, the vibration component inside the first electric conveyor belt causes the belt body to vibrate, which in turn causes the slag on the upper surface of the first electric conveyor belt to vibrate. At this time, the strong magnetic plate inside the second electric conveyor belt can adsorb the heavier magnetic substances in the slag. Meanwhile, the second electric conveyor belt transports the magnetic substances to the right and discharges them through the first discharge port, which can remove the heavier magnetic metal substances in the slag.

[0019] Three-stage magnetic separation: The magnetically separated slag falls onto the upper surface of the third electric conveyor belt, which transports the slag to the left. When the slag reaches the leftmost end of the third electric conveyor belt, the drive roller at the left end of the third electric conveyor belt rotates continuously, and the magnets inside the drive roller rotate synchronously. Since the magnetic poles of two adjacent magnets are opposite, eddy currents can be generated inside the non-magnetic metal material of the slag. Moreover, the alternating magnetic field generated by the eddy current is opposite to the alternating magnetic field of the magnet, thereby generating a repulsive force on the non-magnetic metal material, throwing the non-magnetic metal material in the slag to the left and discharging it through the second discharge port, which facilitates the separation of non-magnetic metal material in the slag.

[0020] Screening: The slag that has been magnetically separated falls onto the upper surface of the screen plate. The second vibrating motor on the bottom of the screen plate works to make the screen plate vibrate and screen the slag again, making the slag screening more thorough.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The comprehensive treatment center for waste incineration slag and its treatment process have the following advantages:

[0022] 1. After incineration, the slag is fed into the shell through a hopper. Simultaneously, the controller controls the drive motor to rotate the lower right roller, which, through gears, causes the lower left roller to rotate synchronously in the opposite direction. Two belts simultaneously convey the slag in opposite directions. Because the lower rollers are permanent magnet rollers, when the slag falls between them, the lighter magnetic materials within the slag are attracted to the surface of the belts. As the belts convey the slag, the magnetic materials fall onto both sides of the guide plates and are discharged through symmetrically arranged openings on the front side of the shell. The magnetically separated slag falls through the gaps in the guide plates onto the upper surface of the first electric conveyor belt. The controller operates the first electric conveyor belt to transport the slag to the right. Simultaneously, the controller controls the first vibration motor on the bottom of the vibrating plate to vibrate the belt body of the first electric conveyor belt, which in turn vibrates the slag at the upper end of the first electric conveyor belt. At this time, the strong magnetic plate inside the second electric conveyor belt can attract the heavier magnetic materials in the slag. At the same time, the controller controls the second electric conveyor belt to transport the magnetic materials to the right. When the magnetic materials are transported to the point of separation from the strong magnetic plate, the magnetic materials are discharged through the first discharge port. This process can perform multi-stage separation of magnetic metal materials in the slag, making the separation of magnetic metal materials in the slag more thorough.

[0023] 2. As the slag falls, the controller controls the feeding motor to work, which drives the two end face gears to rotate synchronously in opposite directions through the gears. At the same time, the mounting shaft and the feeding frame rotate synchronously in opposite directions. The inner feeding plate and the outer feeding plate cooperate to break up and separate the slag, so as to avoid the slag from clumping after combustion and affecting the subsequent screening, thus ensuring the quality of the subsequent screening.

[0024] 3. The slag after magnetic separation falls onto the upper surface of the screen plate. The second vibration motor on the bottom of the screen plate works, causing the screen plate to vibrate and screen the slag again. At the same time, the support spring inside the support cylinder can provide elastic support for the sliding of the support rod, thereby increasing the vibration force of the screen plate and making the slag screening more thorough, which is convenient for subsequent recycling.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-5 The present invention provides a technical solution: a comprehensive treatment center for waste incineration slag and its treatment process, comprising an outer shell 1 and a magnetic separation unit 2;

[0033] Outer shell 1: A hopper 14 is provided at the upper opening. Rollers 5 are evenly rotatably connected at the gap between the upper ends of the front and rear inner walls of the outer shell 1. Two vertically corresponding rollers 5 are connected by a belt 6. The front ends of the two lower rollers 5 extend to the outside of the outer shell 1 and are equipped with gears at their ends. The two gears are meshed together. A drive motor 17 is provided on the rear side of the outer shell 1. The output shaft of the drive motor 17 is fixedly connected to the rear end of the lower right roller 5. The two lower rollers 5 are permanent magnet rollers. Guide plates 7 corresponding to the belt 6 are symmetrically arranged on the left and right sides of the center of the inner shell 1. It also includes a material feeding mechanism. Unit 4, the feeding unit 4, is rotatably connected between the front and rear inner walls of the outer casing 1. The feeding unit 4 is located between the two belts 6 and corresponds to the discharge port of the hopper 14. The feeding unit 4 includes a feeding frame 41, an inner feeding plate 42, a mounting shaft 43, and an outer feeding plate 44. The feeding frame 41 is rotatably connected between the front and rear inner walls of the outer casing 1. The feeding frame 41 is located between the two belts 6 and corresponds to the discharge port of the hopper 14. The outer feeding plate 44 is symmetrically arranged in the middle of the feeding frame 41. The mounting shaft 43 is rotatably connected inside the feeding frame 41. The inner feeding plate 44 is arranged in the middle of the mounting shaft 43. 2. The rear end of the mounting shaft 43 extends to the outside of the feeding frame 41. Both the rear end of the mounting shaft 43 and the rear end of the feeding frame 41 are equipped with end face gears 16. The rear side of the outer casing 1 is equipped with a feeding motor 15. The lower end of the output shaft of the feeding motor 15 is equipped with a gear. Both end face gears 16 are meshed with the gear. The slag after the waste incineration is fed into the interior of the outer casing 1 through the hopper 14. At the same time, the drive motor 17 drives the lower right roller 5 to rotate. The gear causes the lower left roller 5 to rotate synchronously in the opposite direction. At the same time, the two belts 6 convey in the opposite direction. Since the two lower rollers 5 are permanent magnet rollers... The slag is drawn between the two lower rollers 5, so when the slag falls between the two rollers 5, the lighter magnetic material in the slag can be adsorbed onto the surface of the belt 6. As the belt 6 is conveyed, the magnetic material falls to both sides of the guide plate 7 and is discharged through the symmetrically arranged openings on the front side of the outer shell 1. At the same time as the slag falls, the feeding motor 15 works, which drives the two end face gears 16 to rotate synchronously in opposite directions through the gears. At the same time, the mounting shaft 43 and the feeding frame 41 rotate synchronously in opposite directions. The inner feeding plate 42 and the outer feeding plate 44 cooperate to crush and separate the slag, so as to avoid the slag after combustion from clumping and affecting the subsequent screening.

[0034] Magnetic separation unit 2: Located inside the outer casing 1. The right side of the outer casing 1 has a first discharge port 8 that cooperates with the magnetic separation unit 2. The lower end of the inner casing 1 has a third electric conveyor belt 9 corresponding to the magnetic separation unit 2. The left end of the outer casing 1 has a second discharge port 10 corresponding to the third electric conveyor belt 9. The magnetic separation unit 2 includes a first electric conveyor belt 21, a second electric conveyor belt 22, and a strong magnetic plate 23. Both the first electric conveyor belt 21 and the second electric conveyor belt 22 are located at the center of the inner casing 1. The second electric conveyor belt 22 is located above the first electric conveyor belt 21 and is offset left and right from the first electric conveyor belt 21. The frame of the first electric conveyor belt 21 has a strong magnetic plate 23. The second electric conveyor belt 22 corresponds to the position of the first discharge port 8. The third electric conveyor belt 9 is located at the lower end of the first electric conveyor belt 21. The first electric conveyor belt 21 has a vibration component 3 inside.The vibration assembly 3 includes a vibrating plate 31, a first vibration motor 311, top columns 32, sliding sleeves 33, springs 34, and a mounting plate 35. The mounting plate 35 is disposed inside the frame of the first electric conveyor belt 21. Sliding sleeves 33 are evenly provided at the four corners of the upper surface of the mounting plate 35. Springs 34 are provided on the bottom surface of each sliding sleeve 33. Top columns 32 are slidably connected inside each sliding sleeve 33. The upper ends of the springs 34 are fixedly connected to the bottom surfaces of the vertically corresponding top columns 32. The upper ends of the four top columns 32 are fixedly connected to the bottom surface of the vibrating plate 31. The bottom surface of the vibrating plate 31 is provided with the first vibration motor 311. 11. Magnets 91 are evenly distributed inside the transmission roller on the left side of the third electric conveyor belt 9. The magnetic poles of two adjacent magnets 91 are opposite. The slag after magnetic separation falls through the gap of the guide plate 7 onto the upper surface of the first electric conveyor belt 21. The controller 18 controls the first electric conveyor belt 21 to work and transport the slag to the right. At the same time, the controller 18 controls the first vibration motor 311 on the bottom surface of the vibration plate 31 to work, so that the belt body of the first electric conveyor belt 21 vibrates, thereby causing the slag at the upper end of the first electric conveyor belt 21 to vibrate. At this time, the strong magnetic plate 23 inside the second electric conveyor belt 22 can... The heavier magnetic materials in the slag are adsorbed, and the controller 18 controls the second electric conveyor belt 22 to transport the magnetic materials to the right. When the magnetic materials are transported to the point where they separate from the strong magnetic plate 23, they are discharged through the first discharge port 8, making the separation of magnetic metal materials in the slag more thorough. The spring 34 and the top column 32 inside the sliding sleeve 33 can provide elastic support for the vibrating plate 31, thereby increasing the vibration force of the vibrating plate 31. The magnetically separated slag falls onto the upper surface of the third electric conveyor belt 9, and the controller 18 controls the third electric conveyor belt 9 to move the slag towards the upper surface of the third electric conveyor belt 9. Left conveying: When the slag is conveyed to the leftmost end of the third electric conveyor belt 9, as the drive roller at the left end of the third electric conveyor belt 9 rotates continuously, the magnets 91 inside the drive roller rotate synchronously. Since the magnetic poles of two adjacent magnets 91 are opposite, eddy currents are generated inside the non-magnetic metallic material of the slag. Moreover, the alternating magnetic field generated by the eddy currents is opposite in direction to the alternating magnetic field of the magnets 91, thereby generating a repulsive force on the non-magnetic metallic material, throwing the non-magnetic metallic material in the slag to the left and discharging it through the second discharge port 10, thus separating the non-magnetic metallic material in the slag.

[0035] Among them: the front side of the outer casing 1 is equipped with a controller 18. The input end of the controller 18 is electrically connected to an external power source. The input ends of the third electric conveyor belt 9, the drive motor 17, the first electric conveyor belt 21, the second electric conveyor belt 22, the first vibration motor 311, and the unloading motor 15 are all electrically connected to the output end of the controller 18 to ensure the normal operation of the circuit.

[0036] The system includes a sieve plate 11, the left end of which is rotatably connected to the lower end of the inner wall of the outer casing 1 via a pin. The sieve plate 11 is located at the lower end of the first electric conveyor belt 21. A second vibration motor 12 is symmetrically arranged on the right side of the bottom surface of the sieve plate 11. A support assembly 13 is symmetrically rotatably connected to the middle of the bottom surface of the sieve plate 11. The lower ends of the support assemblies 13 are rotatably connected to the lower end of the inner wall of the outer casing 1. The input end of the second vibration motor 12 is electrically connected to the output end of the controller 18. The support assembly 13 includes a support rod 131, a support spring 132, and a support cylinder 133. The support cylinder 133 is symmetrically rotatably connected to the lower end of the inner wall of the outer casing 1. The interior of the support cylinder 133 is slidably connected. A support rod 131 is attached, and the upper end of the support rod 131 is rotatably connected to the bottom surface of the screen plate 11. Support springs 132 are movably sleeved at both the upper and lower ends of the support rod 131. The support springs 132 are located inside the support cylinder 133 on the same side. The slag that has been magnetically separated falls onto the upper surface of the screen plate 11. The second vibration motor 12 on the bottom surface of the screen plate 11 works, causing the screen plate 11 to vibrate and screen the slag again. While the screen plate 11 vibrates, the support springs 132 inside the support cylinder 133 can provide elastic support for the sliding of the support rod 131, thereby increasing the vibration force of the screen plate 11 and making the slag screening more thorough, which is convenient for subsequent recycling.

[0037] A treatment process for a comprehensive waste incineration slag treatment center includes the following steps:

[0038] Primary magnetic separation: The slag from the incineration of waste is fed into the interior of the outer shell 1 through the hopper 14. At the same time, the drive motor 17 drives the lower right roller 5 to rotate. The lower left roller 5 is rotated synchronously in the opposite direction through gears. Meanwhile, the two belts 6 convey the slag in the opposite direction. Since the two lower rollers 5 are permanent magnet rollers, when the slag falls between the two lower rollers 5, the lighter magnetic materials in the slag can be adsorbed onto the surface of the belt 6. As the belt 6 is conveyed, the magnetic materials fall to both sides of the guide plate 7, which facilitates the separation and removal of magnetic metal materials in the slag.

[0039] Secondary magnetic separation: The magnetically separated slag falls onto the upper surface of the first electric conveyor belt 21. The first electric conveyor belt 21 transports the slag to the right. The controller 18 controls the first vibration motor 311 on the bottom of the vibration plate 31 to work, causing the belt of the first electric conveyor belt 21 to vibrate, which in turn drives the slag on the upper surface of the first electric conveyor belt 21 to vibrate. At this time, the strong magnetic plate 23 inside the second electric conveyor belt 22 can adsorb the heavier magnetic materials in the slag. At the same time, the controller 18 controls the second electric conveyor belt 22 to work and transport the magnetic materials to the right. When the magnetic materials are transported to the point of separation from the strong magnetic plate 23, the magnetic materials are discharged through the first discharge port 8, making the separation of magnetic metal materials in the slag more thorough.

[0040] Three-stage magnetic separation: The magnetically separated slag falls onto the upper surface of the third electric conveyor belt 9. The third electric conveyor belt 9 transports the slag to the left. When the slag is transported to the leftmost end of the third electric conveyor belt 9, as the drive roller at the left end of the third electric conveyor belt 9 rotates continuously, the magnet 91 inside the drive roller rotates synchronously. Since the magnetic poles of the two adjacent magnets 91 are opposite, eddy currents can be generated inside the non-magnetic metal material of the slag. Moreover, the alternating magnetic field generated by the eddy current is opposite to the alternating magnetic field of the magnet 91, thereby generating a repulsive force on the non-magnetic metal material, throwing the non-magnetic metal material in the slag to the left and discharging it through the second discharge port 10.

[0041] Screening: The slag that has been magnetically separated falls onto the upper surface of the screen plate 11. The second vibration motor 12 on the bottom surface of the screen plate 11 works to make the screen plate 11 vibrate and screen the slag again. At the same time as the screen plate 11 vibrates, the support spring 132 inside the support cylinder 133 can provide elastic support for the sliding of the support rod 131, thereby increasing the vibration force of the screen plate 11, making the slag screening more thorough and facilitating subsequent recycling.

[0042] In operation: After incineration, slag is fed into the outer casing 1 through hopper 14. Simultaneously, controller 18 controls drive motor 17 to rotate the lower right roller 5. Gears cause the lower left roller 5 to rotate synchronously in the opposite direction. Two belts 6 convey the slag in the opposite direction. Since the lower rollers 5 are permanent magnet rollers, when the slag falls between them, the lighter magnetic material within the slag adheres to the surface of belts 6. As belts 6 convey the slag, the magnetic material falls onto both sides of guide plates 7 and is discharged through symmetrically arranged openings on the front side of the outer casing 1. Simultaneously, controller 18 controls the feeding motor 15 to operate, driving two end-face gears 16 to rotate synchronously in the opposite direction. Simultaneously, the mounting shaft 43 and the material feeding frame 41 rotate in opposite directions. The inner material feeding plate 42 and the outer material feeding plate 44 cooperate to crush and separate the slag, preventing the slag from agglomerating after combustion and affecting subsequent screening. The magnetically separated slag falls through the gap of the guide plate 7 onto the upper surface of the first electric conveyor belt 21. The controller 18 controls the first electric conveyor belt 21 to work and transport the slag to the right. At the same time, the controller 18 controls the first vibration motor 311 on the bottom surface of the vibrating plate 31 to work, causing the belt of the first electric conveyor belt 21 to vibrate, which in turn causes the slag at the upper end of the first electric conveyor belt 21 to vibrate. At this time, the strong magnetic plate 23 inside the second electric conveyor belt 22 can attract the heavier magnetic substances in the slag, and at the same time control... The controller 18 controls the second electric conveyor belt 22 to transport the magnetic material to the right. When the magnetic material is transported to the point where it separates from the strong magnetic plate 23, it is discharged through the first discharge port 8. The spring 34 and the top column 32 inside the sliding sleeve 33 provide elastic support for the vibrating plate 31, thereby increasing the vibration force of the vibrating plate 31. The magnetically separated slag falls onto the upper surface of the third electric conveyor belt 9. The controller 18 controls the third electric conveyor belt 9 to transport the slag to the left. When the slag is transported to the leftmost end of the third electric conveyor belt 9, as the drive roller at the left end of the third electric conveyor belt 9 rotates continuously, the magnet 91 inside the drive roller rotates synchronously. Since the magnetic poles of two adjacent magnets 91 are opposite, the slag can be... Eddy currents are generated inside the non-magnetic metallic material, and the alternating magnetic field generated by the eddy currents is opposite to the alternating magnetic field of the magnet 91, thus generating a repulsive force on the non-magnetic metallic material. This throws the non-magnetic metallic material in the slag to the left and discharges it through the second discharge port 10. The slag that has been magnetically separated falls onto the upper surface of the screen plate 11. The controller 18 controls the second vibration motor 12 on the bottom surface of the screen plate 11 to work, so that the screen plate 11 vibrates to screen the slag again. At the same time as the screen plate 11 vibrates, the support spring 132 inside the support cylinder 133 can provide elastic support for the sliding of the support rod 131, thereby increasing the vibration force of the screen plate 11, making the slag screening more thorough, and facilitating subsequent recycling.

[0043] It is worth noting that the third electric conveyor belt 9, drive motor 17, first electric conveyor belt 21, second electric conveyor belt 22, first vibrating motor 311, second vibrating motor 12, and unloading motor 15 disclosed in this embodiment can be freely configured according to the actual application scenario. It is recommended that the first electric conveyor belt 21, second electric conveyor belt 22, and third electric conveyor belt 9 be PVC rubber conveyors. It is recommended that the unloading motor 15 and drive motor 17 be motors of model 5IK150RGU-CF.

4. The treatment process of a comprehensive waste incineration slag treatment center according to any one of claims 1-3, characterized in that: Includes the following steps: Primary magnetic separation: The slag after the waste incineration is fed into the interior of the outer shell (1) through the hopper (14). At the same time, the drive motor (17) drives the lower right roller (5) to rotate. The lower left roller (5) is rotated synchronously in the opposite direction through the gear. At the same time, the two belts (6) transport in the opposite direction. Since the two lower rollers (5) are permanent magnet rollers, when the slag falls between the two lower rollers (5), the lighter magnetic material in the slag can be adsorbed on the surface of the belt (6). As the belt (6) is transported, the magnetic material falls on both sides of the guide plate (7). Secondary magnetic separation: The magnetically separated slag falls onto the upper surface of the first electric conveyor belt (21). The first electric conveyor belt (21) transports the slag to the right. At the same time, the vibration component (3) inside the first electric conveyor belt (21) causes the belt body of the first electric conveyor belt (21) to vibrate, thereby causing the slag on the upper surface of the first electric conveyor belt (21) to vibrate. At this time, the strong magnetic plate (23) inside the second electric conveyor belt (22) can adsorb the heavier magnetic materials in the slag. At the same time, the second electric conveyor belt (22) works to transport the magnetic materials to the right and discharge them through the first discharge port (8). Three-stage magnetic separation: The magnetically separated slag falls onto the upper surface of the third electric conveyor belt (9). The third electric conveyor belt (9) transports the slag to the left. When the slag is transported to the leftmost end of the third electric conveyor belt (9), as the transmission roller at the left end of the third electric conveyor belt (9) rotates continuously, the magnet (91) inside the transmission roller rotates synchronously. Since the magnetic poles of the two adjacent magnets (91) are opposite, eddy currents can be generated inside the non-magnetic metal material of the slag. Moreover, the alternating magnetic field generated by the eddy current is opposite to the alternating magnetic field of the magnet (91), thereby generating a repulsive force on the non-magnetic metal material, throwing the non-magnetic metal material in the slag to the left and discharging it through the second discharge port (10). Screening: The slag that has been magnetically separated falls onto the upper surface of the screen plate (11). The second vibration motor (12) on the bottom surface of the screen plate (11) works to make the screen plate (11) vibrate and screen the slag again.
