Description

Technical Field

[0001] This utility model relates to the field of waste-to-energy plants, specifically to a magnetic separation device for iron metal in the slag of waste-to-energy plants. Background Technology

[0002] In recent years, with the increasingly severe situation of "garbage besieging the city", waste incineration power generation has received more and more attention as the best way to dispose of municipal solid waste in a "reduced, harmless and resource-oriented" manner. The raw materials for waste incineration power generation are diverse, including metal iron products. In order to prevent damage to some equipment in the power plant, it is necessary to remove the metal iron products.

[0003] Existing metal removal devices in waste-to-energy plants typically involve spreading slag flat on a feeding belt and installing a magnetic suction device at the top of the belt. During the slag feeding process, metal objects inside the slag are magnetically removed. However, the magnetic suction range of the magnetic suction device is limited, resulting in a narrow gap between the magnetic suction device and the feeding belt. When dealing with large amounts of slag, it is difficult to quickly remove metal objects, reducing the overall magnetic suction efficiency. Furthermore, the narrow gap between the magnetic suction device and the feeding belt makes it easy for metal objects adsorbed on the magnetic suction device to be scraped off when waste passes through, thus affecting the overall metal removal effect.

[0004] In summary, in order to ensure the overall magnetic attraction effect, the gap between the magnetic attraction device and the feeding belt is set relatively narrow. When faced with a large amount of slag, it is difficult to remove metal products quickly. Furthermore, the metal products adsorbed on the magnetic attraction device are easily scraped off when the slag passes through, thus affecting the overall metal product removal effect. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a magnetic separation device for iron metal in the slag of waste-to-energy plants, so as to solve the technical problems that the gap between the magnetic suction device and the feeding belt is too narrow, making it difficult to quickly remove metal products when facing a large amount of slag, and that the metal products adsorbed on the magnetic suction device are easily scraped off when the slag passes through.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic separation device for iron element metal in slag from a waste-to-energy plant, comprising a frame, a support at the top of the frame, and a top plate connected to the top of the support. A drive assembly is provided on one side of the frame, and a feeding mechanism is connected to the output end of the drive assembly through the frame. A rotating component is rotatably provided on the inner side of the feeding mechanism, and the rotating component is connected to the feeding mechanism through a second transmission mechanism. The other end of the rotating component is connected to a first transmission mechanism, and the other end of the first transmission mechanism is connected to a shaped gear at the top plate. A reciprocating disk that cooperates with the shaped gear is slidably provided on one side of the top plate, and a magnetic suction assembly is connected to the reciprocating disk through the top plate.

[0007] By adopting the above technical solution, the rotating component will drive the feeding mechanism to vibrate, ensuring that the garbage on the feeding mechanism is pushed upward. During this process, the large gap between the magnetic suction component and the feeding mechanism will not affect the magnetic suction component's adsorption of metal products, ensuring that more garbage is magnetically separated each time, thus improving the overall magnetic separation efficiency of the device. Furthermore, under the action of the first transmission mechanism, the irregular gear is driven to rotate, and through the action of the toothed blocks in the reciprocating disc, the magnetic suction component is driven to reciprocate, thereby making full use of the magnetic suction component.

[0008] The present invention is further configured such that the driving component is a feeding motor, which is used to drive the feeding mechanism to rotate and feed materials.

[0009] By adopting the above technical solution, the feeding belt is conveyed at different speeds under the action of the feeding motor, which makes it easy for the staff to adjust its conveying efficiency and further improves the overall practicality of the device.

[0010] The present invention is further configured such that a tooth block that cooperates with a non-standard gear is partially provided inside the reciprocating disk, and the tooth blocks are symmetrically arranged on the inner side of the reciprocating disk.

[0011] By adopting the above technical solution, the irregular gear will mesh with the tooth block during the rotation of the irregular gear, thereby driving the reciprocating disk to move to one side. Since the tooth block is located at the upper and lower ends of the irregular gear, the reciprocating disk will be driven to slide back and forth during the rotation of the irregular gear.

[0012] The present invention is further configured such that the second transmission mechanism includes a driving disc, a transmission belt and a driven disc, the driving disc and the driven disc are connected by the transmission belt, one end of the feeding mechanism is connected to the driving disc, and a rotating component is connected to one end of the driven disc, wherein the diameter of the driving disc in the second transmission mechanism is larger than the diameter of the driven disc.

[0013] By adopting the above technical solution, when the feeding mechanism is driven to rotate by the feeding motor, the active disk will rotate accordingly. Due to the action of the transmission belt, the driven disk also rotates accordingly, so that the rotating part rotates inside the feeding mechanism. In the second transmission mechanism, the diameter of the active disk is larger than the diameter of its driven disk. Therefore, when the feeding mechanism drives the active disk to rotate several times, the driven disk will drive the rotating part to rotate several times. During this process, the slag on the feeding mechanism is quickly shaken, which facilitates the adsorption of metal products by the magnetic attraction component.

[0014] The present invention is further provided that a slot is provided on the top plate at the reciprocating plate.

[0015] By adopting the above technical solution, the slotting function facilitates the movement of the magnetic suction component during the sliding process of the reciprocating disc.

[0016] The present invention is further configured such that the magnetic suction assembly includes a card plate and an electromagnet, one end of the reciprocating disc extends through the top plate and is connected to the card plate, and the electromagnet is detachably installed inside the card plate.

[0017] By adopting the above technical solution, when the reciprocating disc slides, the card plate moves at the slot. Since the card plate is detachably equipped with an electromagnet, the reciprocating disc drives the electromagnet to move back and forth at the bottom of the top plate, thereby completing the adsorption of metal products.

[0018] The present invention is further configured such that the bracket itself is telescopic.

[0019] By adopting the above technical solution, staff can adjust the overall height of the support according to the actual situation, further improving the overall practicality of the device.

[0020] The present invention is further configured such that the connection between the reciprocating disc and the top plate is smooth.

[0021] By adopting the above technical solution, the smooth shape helps to reduce the sliding friction between the two, ensuring the stability of the reciprocating disc sliding on the side wall of the top plate.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention features a rotating component inside the feeding mechanism. During the feeding process, the rotating component rotates rapidly under the action of a second transmission mechanism. This rotation causes the feeding mechanism to vibrate, ensuring that the slag on the feeding mechanism is lifted upwards. The relatively large distance between the magnetic suction component and the feeding mechanism does not affect the magnetic suction component's adsorption of metal products, ensuring that a larger amount of slag is magnetically separated each time, thus improving the overall magnetic separation efficiency of the device. Furthermore, the first transmission mechanism drives the shaped gear to rotate, which, through its interaction with the toothed blocks in the reciprocating disc, drives the magnetic suction component to move back and forth, fully utilizing the magnetic suction component and ensuring that the bottom of the magnetic suction component adsorbs the metal products.

[0030] 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.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1

[0033] A magnetic separation device for iron metal in waste-to-energy plant slag, such as... Figures 1-5As shown, the device includes a frame 1, a top plate 5, a magnetic suction assembly 13, a transmission mechanism, and a sliding mechanism. A support 8 is located at the top of the frame 1, and the top plate 5 is connected to the top of the support 8. A feeding motor 2 is installed on one side of the frame 1, and a feeding mechanism 3 is connected to the output end of the feeding motor 2, extending into the frame 1. Workers place the slag to be magnetically separated on the top of the feeding mechanism 3, and then start the feeding motor 2 on one side to move the feeding mechanism 3 to one side. A rotating component 10 is rotatably installed inside the feeding mechanism 3, and the rotating component 10 is connected to the feeding mechanism 3 via a second transmission mechanism 9. During the rotation and feeding process of the feeding mechanism 3, the rotating component 10 rotates under the action of the second transmission mechanism 9, ensuring that the slag on the feeding mechanism 3 is lifted upwards. During this process, the large distance between the magnetic suction assembly 13 and the feeding mechanism 3 does not affect the magnetic suction assembly 13's adsorption of metal products, ensuring that a larger amount of slag is magnetically separated each time, thus improving the overall magnetic separation efficiency of the device.

[0034] Meanwhile, a first transmission mechanism 4 is connected to the other end of the rotating part 10, and a special-shaped gear 11 is connected to the other end of the first transmission mechanism 4 at the top plate 5. A reciprocating disk 6 that cooperates with the special-shaped gear 11 is slidably arranged on one side of the top plate 5, and a magnetic suction component 13 is connected to the top plate 5 through one side of the reciprocating disk 6. A toothed block 12 that cooperates with the special-shaped gear 11 is partially arranged in the reciprocating disk 6, and the toothed block 12 is symmetrically arranged on the inner side of the reciprocating disk 6. During the rotation of the special-shaped gear 11, it will mesh with the toothed block 12, thereby driving the reciprocating disk 6 to move to one side. Since the toothed block 12 is located at the upper and lower ends of the special-shaped gear 11, the reciprocating disk 6 will be driven to slide back and forth during the rotation of the special-shaped gear 11, thereby driving the magnetic suction component 13 to move back and forth, so as to make full use of the magnetic suction component 13 and ensure that the bottom of the magnetic suction component 13 can attract metal products.

[0035] Please see Figure 4 A slot 7 is provided on the top plate 5 at the reciprocating plate 6. The slot 7 facilitates the movement of the magnetic suction component 13 during the sliding of the reciprocating plate 6. The magnetic suction component 13 includes a card plate and an electromagnet. One end of the reciprocating plate 6 extends into the top plate 5 and is connected to the card plate. An electromagnet is detachably installed inside the card plate. When the reciprocating plate 6 slides, the card plate moves at the slot 7. Since the electromagnet is detachably installed inside the card plate, the reciprocating plate 6 drives the electromagnet to move back and forth at the bottom of the top plate 5, thereby completing the adsorption of metal products.

[0036] Example 2

[0037] like Figure 2The magnetic separation device for iron element metal in slag from a waste-to-energy plant shown is similar in overall structure to that in Embodiment 1. The second transmission mechanism 9 includes an active disc, a transmission belt, and a driven disc. One end of the feeding mechanism 3 is connected to the active disc, and the other end of the driven disc is connected to a rotating component 10. When the feeding mechanism 3 is driven to rotate by the feeding motor 2, the active disc will rotate accordingly. Due to the action of the transmission belt, the driven disc also rotates, causing the rotating component 10 to rotate inside the feeding mechanism 3. Since the diameter of the active disc in the second transmission mechanism 9 is larger than the diameter of its driven disc, when the feeding mechanism 3 drives the active disc to rotate several times, the driven disc will drive the rotating component 10 to rotate several times. During this process, the slag on the feeding mechanism 3 is rapidly shaken, which facilitates the adsorption of metal products by the magnetic attraction component 13.

[0038] The working principle of this utility model is as follows: In use, the top plate 5 is installed on the top of the frame 1 under the action of the bracket 8. Then, the feeding mechanism 3 is driven to rotate and feed material under the action of the feeding motor 2. The operator places the slag to be magnetically separated on the top of the feeding mechanism 3. During the rotation of the feeding mechanism 3, the rotating part 10 inside the feeding mechanism 3 is driven to rotate under the action of the second transmission mechanism 9. At this time, the feeding mechanism 3 is reciprocated and shaken under the action of the rotating part 10, which lifts the slag on the top upward. At this time, the metal products in the waste will be attracted by the magnetic suction component 13. At the same time, the special gear 11 is driven to rotate under the action of the first transmission mechanism 4. Through the cooperation of the special gear 11 and the tooth block 12, the magnetic suction component 13 is driven to slide back and forth at the bottom of the top plate 5. During this process, it is ensured that the bottom of the magnetic suction component 13 is attracted to the metal products, so as to make full use of the magnetic suction component 13.
