Description

Technical Field

[0001] This utility model relates to the field of eddy current separators, specifically an eddy current separator for waste incinerator slag. Background Technology

[0002] Eddy current separators are environmentally friendly equipment that uses the principle of electromagnetic induction to efficiently separate non-ferrous metals from slag. The core component, a permanent magnet drum, rotates at high speed to generate an alternating magnetic field, which causes eddy currents to be generated inside conductive metals (such as copper and aluminum) and subjected to repulsive forces, thereby separating them from non-metallic slag. This technology has advantages such as dry separation, no need for chemical reagents, and large processing capacity, and is particularly suitable for processing metal particles coated with oxides.

[0003] Current eddy current separators can separate metals from slag during operation, improving the recycling rate of waste. However, there is a problem in actual operation: after the slag is transported by conveyor belt and subjected to magnetic separation, some slag adheres to the surface of the conveyor belt, causing delayed falling and making it difficult to collect the slag effectively. Therefore, the inventors urgently need to design a slag collection mechanism to improve the centralized collection of slag after separation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an eddy current separator for waste incinerator slag, so as to solve the technical problems of conveyor belt adhesion, delayed falling and non-concentrated collection in the eddy current separator during the slag processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an eddy current separator for waste incinerator slag, comprising a support frame, a conveyor belt installed on the inner side of the support frame, a support frame provided below the inner side of the support frame, a baffle mechanism installed on one side above the support frame, a first collection frame placed on the inner side of the support frame, and a cleaning mechanism installed on the upper part of the support frame. The cleaning mechanism includes a chute and a mounting plate. The mounting plate is slidably connected to a support frame via the chute. A mounting base is installed above the mounting plate. An air outlet is opened on the top surface of the mounting base. The air outlet is opposite to the bottom surface of the conveyor belt. The mounting plate and the mounting base form an inner cavity that communicates with the air outlet. A connecting pipe is installed on one side of the mounting plate. The connecting pipe is connected to an external air pump device via a solenoid valve.

[0006] By adopting the above technical solution, a uniform airflow field can be formed in the inner cavity after the air pump is connected to the connecting pipe. When the high-pressure gas is sprayed obliquely from the air outlet of the mounting base to the bottom surface of the conveyor belt, it can apply a continuous impact force to the surface of the belt in operation, directly peeling off the fine slag particles adhering to the surface of the conveyor belt, thus solving the problem of material residue caused by electrostatic adsorption or moisture adhesion in traditional equipment from the root.

[0007] Furthermore, mounting screws are fixedly installed on both sides of the mounting plate, and the two sides of the mounting plate are detachably connected to the support frame through mounting screws and mounting nuts.

[0008] By adopting the above technical solution, the locking mechanism consisting of the mounting screw and the mounting nut is symmetrically distributed on both sides of the mounting plate, so that the cleaning mechanism and the support frame form a rigid and detachable connection. This structure utilizes the precise fit characteristics of the screw thread to ensure the vibration and displacement stability of the mounting plate while achieving micron-level precision adjustment of the airflow jet height, ensuring that the air outlet always maintains the optimal blowing distance from the bottom surface of the conveyor belt.

[0009] Furthermore, the top surface of the mounting base is sloping, which is used to blow air at an angle to the bottom surface of the conveyor belt, and to blow away debris adhering to the surface of the conveyor belt.

[0010] By adopting the above technical solution, the inclined structure on the top surface of the mounting base guides the airflow to form an inclined jet through a specific tilt angle design. When this directional airflow contacts the bottom surface of the conveyor belt, it generates an outward tangential component force. At the same time, the inclined blowing path and the running direction of the conveyor belt form a synergistic force field, causing the stripped debris to be thrown off the belt surface along a parabolic trajectory.

[0011] Furthermore, a magnetic separator roller is installed on the inner side of the conveyor belt, and a drive mechanism is installed on one side of the magnetic separator roller.

[0012] By adopting the above technical solution, the magnetic separator is built into the closed-loop running path of the conveyor belt. The drive mechanism drives the permanent magnet to rotate at high speed, so that when the slag material carried by the conveyor belt enters the strong alternating magnetic field area, it generates a full eddy current effect, ensuring that the conductive metal particles obtain a strong repulsive force and are accurately ejected and separated.

[0013] Furthermore, a vibrating cloth feeder is installed on one side of the upper part of the support frame, and a second collection frame is placed on the other side of the support frame. The first collection frame is used to collect non-metallic slag, and the second collection frame is used to collect slag containing metal.

[0014] By adopting the above technical solution, the setting of the vibrating cloth feeder at the feeding end of the support frame forms a pre-sorting collaborative system. Its high frequency and low amplitude characteristics enable the incoming slag to form a single-particle thin layer distribution on the conveyor belt, eliminating the metal sorting blind zone caused by material stacking.

[0015] Furthermore, the baffle mechanism includes a first baffle and a second baffle. The first baffle is hinged to the support frame through a hinge joint, and the installation angle of the first baffle is fixed by a locking mechanism.

[0016] By adopting the above technical solution, the first baffle can achieve multi-level angle adjustment through the hinge, so that its tilt angle can accurately match the free fall trajectory of slag with different particle sizes, especially to compensate for the difference in the ejection landing point of sheet-like or spherical metal.

[0017] Furthermore, both the first baffle and the second baffle have mounting grooves on their surfaces. The first baffle and the second baffle are connected by mounting grooves and bolts to form an adjustable structure, which is used to adjust and fix the relative positions of the first baffle and the second baffle.

[0018] By adopting the above technical solution, the staggered layout of the mounting slots of the first baffle and the second baffle forms a multi-degree-of-freedom adjustment system. The vertical height difference between the two baffles can be adjusted independently by bolts passing through the slots, thereby improving the environmental adaptability of the baffles.

[0019] Furthermore, an outer side plate is welded to the outside of the support frame to form a semi-open structure for the sorting machine.

[0020] By adopting the above technical solution, the semi-open structure welded along the main outline of the support frame on the outer side plate forms a passive protection system. Its side wall height is calculated to cover the material splash envelope area, and it automatically intercepts accidentally ejected metal chips or slag fragments during operation, fundamentally eliminating safety hazards in the sorting process.

[0021] In summary, the present invention has the following main advantages: 1. In this utility model, the cleaning mechanism achieves flexible positioning of the mounting plate through the sliding groove. Combined with the airflow transported by the connecting pipe, the airflow is sprayed from the inner cavity to the bottom surface of the conveyor belt at an angle to the air outlet, directly destroying the adhesion of the residue and solving the problem of belt surface retention in traditional equipment. At the same time, the airflow purging does not require contact with the parts to avoid wear, ensuring the continuous cleanliness of the conveyor belt during continuous operation and improving the collection concentration of non-metallic slag in the first collection frame. 2. In this utility model, the adjustable baffle mechanism adjusts the angle of the first baffle to match the material trajectory through the hinge part, and works with the second baffle in conjunction with the mounting groove to form a gradually narrowing guide channel, guiding the metal particles to fall accurately into the second collection frame. At the same time, the double baffle design forms an adaptive adjustment mechanism for sorting products under different working conditions, and works with the locking mechanism to maintain angle stability, ensuring the collection and positioning accuracy during the sorting process.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In this embodiment: An eddy current separator for waste incinerator slag, such as Figure 1-5 As shown, it includes a support frame 1, a conveyor belt 2 installed on the inner side of the support frame 1, a support frame 6 provided below the inner side of the support frame 1, a baffle mechanism 9 installed on one side above the support frame 6, a first collection frame 801 placed inside the support frame 6, and a cleaning mechanism 7 installed on the upper part of the support frame 1. The cleaning mechanism 7 includes a chute 701 and a mounting plate 702. The mounting plate 702 is slidably connected to the support frame 1 via the chute 701. A mounting base 705 is mounted on the top of the mounting plate 702. An air outlet 706 is provided on the top surface of the mounting base 705. The air outlet 706 is positioned opposite the bottom surface of the conveyor belt 2. The mounting plate 702 and the mounting base 705 form an inner cavity that communicates with the air outlet 706. A connecting pipe 707 is installed on one side of the mounting plate 702. The connecting pipe 707 is connected to an external air pump device via a solenoid valve. After the connecting pipe 707 is connected to an external air pump, a uniform airflow field can be formed in the inner cavity. When high-pressure gas flows from the air outlet of the mounting base 705... When the 706 is sprayed obliquely onto the bottom surface of the conveyor belt 2, it can apply a continuous impact force to the surface of the running belt, directly peeling off the fine slag particles adhering to the surface of the conveyor belt 2. This solves the problem of material residue caused by electrostatic adsorption or moisture adhesion in traditional equipment from the root. At the same time, the sliding connection structure between the chute 701 and the mounting plate 702 greatly improves the flexibility of the mechanism adjustment, allowing operators to adjust the airflow spray angle and position according to the actual working conditions, thereby adapting to the slag processing needs of different moisture contents and particle sizes. This ensures that the conveyor belt 2 returns to a clean state after each round of sorting, and significantly improves the centralized collection efficiency of non-metallic slag in the first collection frame 801.

[0026] See Figure 1 , Figure 2 , Figure 3 Mounting screws 703 are fixedly installed on both sides of the mounting plate 702. The two sides of the mounting plate 702 are detachably connected to the support frame 1 through the mounting screws 703 and mounting nuts 704. The locking mechanism formed by the mounting screws 703 and mounting nuts 704 is symmetrically distributed on both sides of the mounting plate 702, so that the cleaning mechanism 7 and the support frame 1 form a rigid detachable connection. This structure utilizes the precise fit characteristics of the screw threads to ensure the vibration and displacement stability of the mounting plate 702 while achieving micron-level precision adjustment of the airflow jet height. This ensures that the air outlet 706 always maintains the optimal blowing distance from the bottom surface of the conveyor belt 2. At the same time, it greatly simplifies the equipment maintenance process. When it is necessary to replace worn parts or clean the inner cavity, it is only necessary to remove the mounting nuts 704 to pull out the entire cleaning mechanism 7 along the slide 701. This avoids the disadvantage of the traditional welded structure that requires stopping the machine for cutting, and maximizes the continuous operation of the production line and reduces maintenance costs.

[0027] See Figure 1 , Figure 2 , Figure 3 The top surface of the mounting base 705 is sloping, which allows the air outlet 706 to blow obliquely to the bottom surface of the conveyor belt 2 to sweep away debris adhering to the surface of the conveyor belt 2. The sloping structure of the top surface of the mounting base 705 guides the airflow to form an oblique jet through a specific tilt angle design. When this directional airflow contacts the bottom surface of the conveyor belt 2, it generates an outward tangential force. At the same time, the oblique sweeping path and the running direction of the conveyor belt 2 form a synergistic force field, causing the stripped debris to be thrown off the belt surface along a parabolic trajectory. This effectively prevents the debris from redepositing near the sweeping area, significantly reducing airflow energy consumption while improving the residue removal rate, and achieving efficient and energy-saving continuous cleaning operations.

[0028] See Figure 1 , Figure 2 , Figure 3 A magnetic separator roller 4 is installed on the inner side of the conveyor belt 2. A drive mechanism 3 is installed on one side of the magnetic separator roller 4. The magnetic separator roller 4 is built into the closed-loop running path of the conveyor belt 2. The drive mechanism 3 drives the permanent magnet to rotate at high speed, so that when the slag material carried by the conveyor belt 2 enters the strong alternating magnetic field area, a sufficient eddy current effect is generated. This ensures that the conductive metal particles are accurately ejected and separated by strong repulsive force. At the same time, when the non-metallic slag naturally leaves the belt track under the action of gravity, it is in the magnetic weakening area, avoiding the interference of residual magnetic field and causing mis-sorting of non-metallic materials. Thus, the essential improvement of sorting purity is guaranteed at the physical level.

[0029] See Figure 1 , Figure 2A vibrating feeder 5 is installed on one side above the support frame 1, and a second collection frame 802 is placed on the other side of the support frame 6. The first collection frame 801 is used to collect non-metallic slag, and the second collection frame 802 is used to collect slag containing metal. The vibrating feeder 5 is set at the feeding end of the support frame 1 to form a pre-sorting collaborative system. Its high frequency and low amplitude characteristics make the incoming slag form a single-particle thin layer distribution on the conveyor belt 2, eliminating the blind zone of metal sorting caused by material stacking. At the same time, the first collection frame 801 and the second collection frame 802 are arranged in sections in the support frame 6 to form a dual-channel material collection system. The second collection frame 802 is positioned according to the inertial trajectory of metal ejection, and the first collection frame 801 receives the free-falling non-metallic components.

[0030] See Figure 4 , Figure 5 The baffle mechanism 9 includes a first baffle 901 and a second baffle 902. The first baffle 901 is hinged to the support frame 6 through a hinge part 905, and the installation angle of the first baffle 901 is fixed by a locking mechanism. The first baffle 901 can achieve multi-level angle adjustment through the hinge part 905, so that its tilt angle can accurately match the free fall trajectory of slag with different particle sizes. In particular, it can compensate for the difference in the ejection landing point of sheet-like or spherical metal. At the same time, the locking mechanism provides rigid positioning guarantee, so that the baffle maintains the stability of the preset tilt angle under continuous material impact, avoiding the problem of metal particle scattering caused by impact vibration displacement of traditional fixed baffles.

[0031] See Figure 4 , Figure 5 The surfaces of the first baffle 901 and the second baffle 902 are both provided with mounting grooves 903. The first baffle 901 and the second baffle 902 are adjusted by mounting grooves 903 and bolts to adjust and fix the relative positions of the first baffle 901 and the second baffle 902. The staggered arrangement of the mounting grooves 903 of the first baffle 901 and the second baffle 902 forms a multi-degree-of-freedom adjustment system. The vertical height difference between the two baffles can be adjusted independently by bolts passing through the grooves, thereby improving the environmental adaptability of the baffles. At the same time, the double baffle structure forms a physical energy dissipation mechanism, and the metal particles fall smoothly into the collection area after the kinetic energy is attenuated by multiple collisions.

[0032] See Figure 1 An outer side plate 10 is welded to the outside of the support frame 1 to form a semi-open structure for the sorting machine. The semi-open structure of the outer side plate 10 welded along the main outline of the support frame 1 forms a passive protection system. Its side wall height is calculated to cover the material splash envelope area. During operation, it automatically intercepts accidentally ejected metal chips or slag fragments, fundamentally eliminating safety hazards in the sorting process. At the same time, it solves the risk of magnet demagnetization caused by internal dust heat accumulation in traditional fully enclosed equipment, achieving a unified balance between safety protection and long-term equipment operation.

[0033] The implementation principle of this embodiment is as follows: the material is evenly spread on the surface of the conveyor belt 2 by the vibrating cloth spreader 5, and the conveyor belt 2 is driven by the drive mechanism 3 to run to the area of ​​the magnetic separation roller 4. When the slag containing metal passes through the high-speed rotating magnetic separation roller 4, the conductive metal is ejected and separated by the repulsive force due to the eddy current effect, while the non-metallic slag continues to move towards the end with the conveyor belt 2.

[0034] When the conveyor belt 2 reaches the terminal turning position, the residual slag adhering to its surface should fall off naturally under the action of gravity. At this time, the cleaning mechanism 7 plays a key role: the mounting plate 702 is slidably connected and fixed to the support frame 1 through the slide groove 701, and the external air pump delivers high-pressure airflow to the inner cavity of the mounting base 705 through the connecting pipe 707. The airflow is sprayed obliquely from the air outlet 706 to the bottom surface of the conveyor belt 2, forcibly removing the adhering debris.

[0035] After sorting, the material is precisely guided by the adjustable baffle mechanism 9: the first baffle 901 is tilted by the hinge 905, and the second baffle 902 is adjusted to be in relative position with the first baffle 901 by the mounting groove 903 and bolts, together forming a guide channel. The ejected metal particles fall into the second collection frame 802, while the non-metallic slag is guided by the baffle to fall into the first collection frame 801 inside the support frame 6. The outer plate 10 wraps the support frame 1 to form a semi-enclosed structure, ensuring operational safety and dust control. Through the synergistic effect of airflow cleaning and the angle-adjustable baffle, the integrity and positioning accuracy of the slag collection after sorting are significantly improved.
