Description

Technical Field

[0001] This utility model relates to the field of electromagnetic slag separation technology, specifically to an electromagnetic separation device for waste incineration slag. Background Technology

[0002] The slag from municipal solid waste incineration power plants is mainly a heterogeneous mixture composed of stones, sand, glass, ceramics, ash, and a small amount of unburned waste. After crushing and sorting, the slag has stable chemical properties, good durability, and high strength. Slag is a non-toxic general waste that can be directly landfilled or processed for utilization. The treatment and utilization of slag is a crucial step after waste incineration. On the one hand, slag contains a large amount of iron impurities, which have high recycling value; on the other hand, if these iron impurities are not separated, the subsequent treatment of the slag may be limited, and it may even pose a potential threat to the environment.

[0003] Currently, electromagnetic separation is commonly used to separate iron impurities in slag. However, traditional magnetic separation equipment can usually only perform one separation. Some iron impurities are covered by slag and cannot be fully exposed to the magnetic field, resulting in limited separation effect and difficulty in completely removing iron impurities from slag. Utility Model Content

[0004] The purpose of this invention is to provide an electromagnetic sorting device for waste incineration slag to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic sorting device for waste incineration slag, comprising:

[0006] A material conveying assembly, the material conveying assembly including a support frame, on which a material conveying belt is provided;

[0007] An electromagnetic sorting mechanism includes a frame spanning a material conveying assembly. A first belt is provided on the right side of the frame, and a first iron remover is nested inside the first belt. A second belt is provided on the left side of the frame, and a second iron remover is nested inside the second belt. Multiple stirring assemblies are provided in the upper middle part of the frame, and a drive assembly is provided on the frame to drive the multiple stirring assemblies to rotate synchronously.

[0008] Preferably, a first guide plate is fixed to the front side wall of the support frame at the position corresponding to the first belt, and a second guide plate is fixed to the front side wall of the support frame at the position corresponding to the second belt.

[0009] Preferably, multiple stirring components are located between the first belt and the second belt. Each stirring component includes a rotating shaft that rotates through the top wall of the frame. The lower end of the rotating shaft is connected to a connecting plate, and multiple elastic stirring rods are fixed to the bottom of the connecting plate. These rods can stir and agitate the slag, which is beneficial for the subsequent adsorption of iron impurities by the second iron separator.

[0010] Preferably, the drive assembly includes a geared motor, a worm gear, and multiple worm wheels. The multiple worm wheels are respectively fixedly sleeved on the corresponding rotating shafts. The output end of the geared motor is connected to the worm gear, and the worm gear is connected to the multiple worm wheels for transmission. This ensures that the rotation speed of each stirring component is consistent, thereby ensuring that the slag is uniformly stirred during the sorting process and further improving the sorting effect.

[0011] Preferably, the distance from the bottom of the second iron separator to the top of the conveyor belt is less than the distance from the bottom of the first iron separator to the top of the conveyor belt, so that after the slag is initially separated by the first iron separator, it can be closer to the second iron separator for secondary separation, further improving the adsorption capacity for iron impurities and ensuring the thoroughness of separation.

[0012] Preferably, the width of the first and second iron separators is greater than the width of the conveyor belt, so as to avoid some iron impurities in the slag not being adsorbed due to insufficient width of the iron separators.

[0013] Preferably, multiple partitions are fixed at equal intervals on the outer sides of the first belt and the second belt, so that when the first belt and the second belt move, they can effectively move the iron impurities on them.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. Through two electromagnetic separation processes and the auxiliary stirring of the stirring component, iron impurities in the slag can be effectively separated, greatly improving the thoroughness of the separation;

[0016] 2. The distance from the bottom of the second iron separator to the top of the conveyor belt is less than that from the bottom of the first iron separator to the top of the conveyor belt. This allows the slag to be closer to the second iron separator for secondary separation after the initial separation by the first iron separator, further improving the adsorption capacity for iron impurities and ensuring thorough separation.

[0017] 3. The stirring components ensure that the slag is fully agitated during the sorting process. The elastic stirring rod can adapt to the unevenness of the slag, ensuring that iron impurities are fully exposed in the magnetic field, thereby further improving the sorting effect.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1 to 5 An electromagnetic sorting device for waste incinerator slag, as shown, includes:

[0028] The material conveying assembly includes a support frame 1, on which a material conveying belt 2 is provided;

[0029] The electromagnetic sorting mechanism includes a frame 3, which spans the material conveying assembly. A first belt 4 is provided on the right side of the frame 3, and a first iron remover 5 is nested inside the first belt 4. A second belt 6 is provided on the left side of the frame 3, and a second iron remover 7 is nested inside the second belt 6. Multiple stirring components 8 are provided in the upper middle part of the frame 3. A drive assembly is provided on the frame 3 to drive the multiple stirring components 8 to rotate synchronously.

[0030] A first guide plate 9 is fixed on the front side wall of the support frame 1 at the position corresponding to the first belt 4, and a second guide plate 10 is fixed on the front side wall of the support frame 1 at the position corresponding to the second belt 6.

[0031] Multiple stirring components 8 are located between the first belt 4 and the second belt 6. The stirring component 8 includes a rotating shaft 11, which rotates through the top wall of the frame 3. The lower end of the rotating shaft 11 is connected to a connecting plate 12. Multiple elastic stirring rods 13 are fixed at the bottom of the connecting plate 12, which can stir and turn the slag, which is beneficial to the subsequent adsorption of iron impurities by the second iron remover 7.

[0032] The drive assembly includes a geared motor 14, a worm gear 15, and multiple worm wheels 16. The multiple worm wheels 16 are respectively fixedly sleeved on the corresponding rotating shafts 11. The output end of the geared motor 14 is connected to the worm gear 15. The worm gear 15 and the multiple worm wheels 16 are connected by a transmission, which can ensure that the rotation speed of each stirring component 8 is consistent, thereby ensuring that the slag is uniformly stirred during the sorting process and further improving the sorting effect.

[0033] The distance from the bottom of the second iron separator 7 to the top of the conveyor belt 2 is less than the distance from the bottom of the first iron separator 5 to the top of the conveyor belt 2. This allows the slag to be more closely separated from the first iron separator 5 and then further separated by the second iron separator 7, thereby improving the adsorption capacity for iron impurities and ensuring thorough separation.

[0034] The width of the first iron separator 5 and the second iron separator 7 is greater than the width of the conveyor belt 2, so as to avoid some iron impurities in the slag not being adsorbed due to insufficient width of the iron separator.

[0035] Multiple partitions 17 are fixed at equal intervals on the outer sides of the first belt 4 and the second belt 6, so that when the first belt 4 and the second belt 6 move, they can effectively move the iron impurities on them.

[0036] In this invention, the slag from waste incineration is evenly fed onto the right end of the conveyor belt 2. The conveyor belt 2 drives the slag to move to the left. When the slag passes the first belt 4, the first iron separator 5 performs preliminary adsorption and separation of iron impurities in the slag. The separated slag continues to be conveyed forward. Subsequently, the slag enters the working range of the stirring assembly 8. Multiple stirring assemblies 8 rotate synchronously under the drive of the drive assembly. The elastic stirring rod 13 on the stirring assembly 8 agitates the slag, further separating the iron impurities from the non-iron impurities in the slag. The stirred slag continues to be conveyed forward. When it reaches the second belt 6, the second iron separator 7 performs secondary adsorption and separation of iron impurities in the slag, further improving the sorting effect. The sorted slag falls from the corresponding positions of the first belt 4 and the second belt 6, and is guided by the first guide plate 9 and the second guide plate 10 to be output to the designated areas for subsequent processing and recycling.

[0037] This electromagnetic separation equipment effectively separates iron impurities from slag through two electromagnetic separation processes and auxiliary stirring by the stirring component 8, greatly improving the thoroughness of the separation.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
