[0019] Beneficial effects

[0020] This incinerator slag screening and iron removal device uses a screening assembly consisting of a first chute, a first slider, a second chute, and a second slider. This allows the screen to slide within the screening frame. Simultaneously, a reciprocating assembly on the mounting plate drives the screen in a reciprocating motion, causing the incinerator slag to continuously roll and move on the screen, accelerating the screening process. Compared to manual screening of slag piece by piece, this mechanized screening method significantly improves screening efficiency, enabling the processing of large quantities of incinerator slag in a short time, reducing screening time, and improving overall work efficiency. An adsorption assembly installed on top of the mounting plate effectively adsorbs iron filings from the incinerator slag. During the screening process on the screen, the iron filings are... Attracted by the adsorption components, the slag is separated from other slag. Compared to the potential omissions in manual iron removal, the adsorption components of this device can remove iron filings more comprehensively, improving the iron removal effect and purity. This makes the slag after screening more suitable for subsequent processing or utilization. The screen is inclined within the screening frame, allowing the incinerator slag to roll naturally downwards on the screen, which helps to better separate substances of different particle sizes in the slag. Larger particles remain above the screen, while smaller particles fall through the screen holes, achieving preliminary screening of the slag. This inclined design, combined with the reciprocating motion of the screen, further improves the screening effect and quality, making the screening process more efficient and accurate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See Figures 1-6 A device for screening and removing iron from incinerator slag includes a screening frame 1, a mounting plate 2, an adsorption component 3, and a screening component 4.

[0030] The screening frame 1 is the main structure of the entire device. It is made of sturdy metal materials, such as carbon steel or stainless steel. The internal space is used to hold the incinerator slag to be treated. The screening frame 1 has sufficient strength and stability to withstand the weight of the slag and the impact force during the processing. The mounting plate 2 is fixedly installed on the side of the screening frame 1. It is made of metal plate and is firmly connected to the screening frame 1 by welding or bolting. The main function of the mounting plate 2 is to provide a mounting base for the adsorption component 3 and the reciprocating component 10, so as to ensure that these components can work stably.

[0031] The adsorption component 3 is mainly used to adsorb ferromagnetic substances in incinerator slag.

[0032] The first chute 5 of the screening component 4 is located on both sides of the screening frame 1, providing a smooth track for the sliding of the first slider 6. The first slider 6 is slidably disposed within the first chute 5, and its material is compatible with the screening frame 1, possessing a certain strength and wear resistance. A screen 7 is fixedly disposed between the first sliders 6. By sliding the first slider 6 within the first chute 5, the position of the screen 7 can be adjusted to adapt to different screening requirements. A second chute 8 is located on the side of the screening frame 1, and a second slider 9 is slidably disposed within the second chute 8. The second slider 9 is fixedly disposed with the screen 7. The stability and adjustability of the screen 7 are enhanced by the sliding of the second slider 9 within the second chute 8. The tilt angle of the screen 7 can be controlled more precisely, thereby improving the screening effect. The screen 7 is tilted within the screening frame 1. The screen 7 is made of metal wire mesh or other suitable screening materials. Its aperture size is selected according to the particle size of the incinerator slag and the screening requirements. The position of the screen 7 can be adjusted by the first slider 6 and the second slider 9, so that the slag can flow and be screened better on the screen 7, improving the screening efficiency and accuracy.

[0033] The reciprocating component 10 fixed on the mounting plate 2 has the main function of driving the screen 7 to reciprocate, so that the slag continuously rolls and jumps on the screen 7, thereby screening more effectively and improving the quality and efficiency of screening.

[0034] First, refer to Figure 6 In this embodiment, the first mounting frame 11 of the reciprocating assembly 10 is fixedly mounted on the mounting plate 2 and is made of a sturdy metal material, such as cast iron or alloy steel. It is firmly connected to the mounting plate 2 by welding or bolting. The sliding columns 12 fixedly mounted on both sides of the first mounting frame 11 are also made of metal and are perpendicular to the first mounting frame 11, providing stable support for the second mounting frame 13 and the movable frame 14 above. The second mounting frame 13 fixedly mounted on the top of the sliding column 12 is made of the same material as the first mounting frame 11 and is fixed by welding or bolting. The movable frame 14 slidably mounted between the sliding columns 12 is made of the same material as the sliding columns 12 and has a certain strength and wear resistance. The movable frame 14 is fixedly mounted to the second slider 9. Through this connection method, the movement of the movable frame 14 can drive the screen 7 to reciprocate within the screening frame 1.

[0035] First rocker arms 15 are rotatably mounted on both sides of the first mounting bracket 11. A first gear 16 is connected between the first rocker arms 15 via a key. Second rocker arms 17 are rotatably mounted on both sides of the movable bracket 14. A second gear 18 is connected between the second rocker arms 17 via a key, and the second gear 18 meshes with the first gear 16. A connecting plate 19 is rotatably mounted between the first gear 16 and the second gear 18. When the motor 20 starts, the output shaft of the motor 20 drives the first rocker arms 15 to rotate, and the first rocker arms 15, via the key connection, drive the first gear 16 to rotate. The first gear 16 then... The second gear 18 is driven to rotate by meshing, and the second rocker arm 17 is driven to rotate. Through the action of the connecting plate 19, the moving frame 14 reciprocates on the sliding column 12, thereby realizing the reciprocating screening action of the screen 7. This gear transmission structure can ensure the stability and accuracy of the movement. The motor 20 fixedly installed on the mounting plate 2 serves as the power source of the reciprocating component 10. The power and speed of the motor 20 are selected according to the working requirements of the device to ensure that sufficient power can be provided to drive the screen 7 to perform effective reciprocating motion, so as to improve the screening efficiency.

[0036] Then, refer to Figure 2 In this embodiment, the sleeve 21 of the adsorption component 3 is fixedly installed on both sides of the mounting plate 2. It is made of metal or engineering plastic and is firmly connected to the mounting plate 2 by welding or bolting. The sliding column 22 is slidably installed inside the sleeve 21. The material is compatible with the sleeve 21 and can slide smoothly inside the sleeve 21. The fixing block 23 is fixedly installed on the top of the sliding column 22 for connecting the electromagnet 24. The electromagnet 24, which is compatible with the screen 7, is fixedly installed between the fixing blocks 23. The electromagnet 24 is made of high-performance magnetic material and can generate a strong magnetic field to adsorb ferromagnetic substances in the incinerator slag. By sliding the sliding column 22 inside the sleeve 21, the height of the electromagnet 24 can be adjusted so that it can better contact the slag on the screen 7 and improve the iron removal effect.

[0037] Secondly, see Figure 4 In this embodiment, the folding plate 25 fixedly installed in the second slide 8 is made of metal or engineering plastic and is fixedly installed on both sides of the second slider 9. The design of the folding plate 25 increases the connection stability between the second slider 9 and the screen 7. At the same time, when the screen 7 reciprocates, the folding plate 25 can flexibly deform with the movement of the slider to adapt to the movement requirements of the screen 7 and prevent slag from sliding out of the second slide 8.

[0038] Finally, see Figure 5In this embodiment, a placement groove 26 is provided on the side of the screening frame 1. The size of the placement groove 26 is adapted to the drawer 27 for installing the drawer 27. The drawer 27 is slidably disposed in the placement groove 26 for easy installation and removal. The drawer 27 is made of metal or engineering plastic and has a certain strength and wear resistance. A magnetic plate 28 is detachably installed inside the drawer 27. The magnetic plate 28 is made of permanent magnet material and can further adsorb the ferromagnetic substances remaining in the slag. When the magnetic plate 28 inside the drawer 27 is full of ferromagnetic substances, the magnetic plate 28 can be easily removed from the drawer 27 for cleaning or replacement to ensure the iron removal effect of the device.

[0039] Working principle:

[0040] When using this incinerator slag screening and iron removal device, the incinerator slag to be processed is first poured into the screening frame 1. The motor 20 on the mounting plate 2 is started. The output shaft of the motor 20 drives the first rocker arm 15 to rotate. The first rocker arm 15 drives the first gear 16 to rotate through a key connection. The first gear 16 meshes with the second gear 18, driving the second gear 18 to rotate, which in turn causes the second rocker arm 17 to rotate. Through the action of the connecting plate 19, the moving frame 14 reciprocates on the sliding column 12. The moving frame 14 is fixed to the second slider 9, thereby driving the screen 7 to reciprocate within the screening frame 1.

[0041] The screen 7 is tilted, and during the reciprocating motion, the incinerator slag continuously rolls and moves on the screen 7. Larger slag particles remain above the screen 7, while smaller slag particles fall through the holes of the screen 7, achieving preliminary screening. At the same time, the electromagnet 24 of the adsorption component 3 is energized to generate magnetism, and the sliding column 22 can slide inside the sleeve 21. The height of the electromagnet 24 is adjusted to better adsorb iron filings in the slag, achieving separation of iron filings from other slag. In addition, the magnetic plate 28 inside the drawer 27 also adsorbs residual ferromagnetic substances in the slag.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
