[0002] A large amount of slag will be produced during the waste incineration process. Incineration slag refers to the non-combustible material discharged from the tail end of the furnace bed. It is generally an inorganic substance. They are mainly metal oxides, hydroxides, carbonates and silicates. They also contain larger iron and aluminum containers and other metals that can be directly recycled. These magnetic iron slags usually need to be screened and separated from the slag through a screening device.

A magnetic roller 3 for adsorbing iron slag is fixed, and the rear end of the main rotating shaft 32 of the roller is fixedly connected to the motor shaft of the roller motor 33 fixed on the rear panel of the roller plate 34. The top surface of the roller plate 34 is vertically fixed with a scraper mounting plate 4, and the scraper mounting plate 4 is provided with a scraper opening ring 5 for scraping off the iron slag on the surface of the magnetic roller 3. The scraper mounting plate 4 is provided with a pushing mechanism for pushing the scraper opening ring 5 to move forward and backward. The scraper mounting plate 4 is provided with a guide plate opening 41, and an inclined guide plate 7 is inserted in the guide plate opening 41. The guide plate 7 is fixed to the left and right sides of the scraper opening ring 5 through a guide connecting rod 70.

[0021] The swing mechanism includes a supporting rotation mechanism and a lifting mechanism, the supporting rotation mechanism includes a shaft groove 10, a swing shaft 11 and a supporting telescopic rod 12, the shaft groove 10 is longitudinally opened on the left bottom surface of the slag screening box 1, the front and rear inner walls of the shaft groove 10 are rotatably fixed with the swing shaft 11, the front and rear ends of the rod wall of the supporting telescopic rod 12 are respectively vertically fixed with the supporting telescopic rod 12, the lifting mechanism includes a cam column 2 and a cam motor 22, the cam column 2 is longitudinally arranged directly below the right bottom surface of the slag screening box 1, the surface of the cam column 2 is slidably connected with the right bottom surface of the slag screening box 1, the front and rear surfaces of the cam column 2 are fixed with a cam shaft 20, and the cam shaft 20 is rotatably fixed between two cam brackets 21 arranged longitudinally. A cam motor 22 is installed on the panel of the cam bracket 21 on the rear side of the slag screening box 1, and the motor shaft of the cam motor 22 is fixedly connected to the rear end of the cam shaft 20. The cam column 2 is driven by the cam motor 22 to rotate. When the cam column 2 rotates to the raised end, the cam column 2 pushes the right side of the slag screening box 1 upward as a whole, and the slag screening box 1 rotates counterclockwise with the swing shaft 11 as the rotation axis, so that the slag on the right side of the slag screening box 1 rolls to the left side. When the arc end of the cam column 2 contacts the slag screening box 1, the right side of the slag screening box 1 sinks, and the slag on the left side of the slag screening box 1 rolls to the right, thereby realizing the overall left-right swinging action of the slag screening box 1, and realizing the turning action of the slag contained in the slag screening box 1.

[0022] The scraper opening ring 5 is made of insulating material, and the bottom of the scraper opening ring 5 is provided with an opening 51 for passing the drum rotating rod 31. The distance between the drum rotating rod 31 and the scraper mounting plate 4 is greater than the width of the scraper opening ring 5. The set opening 51 is convenient for the scraper opening ring 5 to push the material left and right, and the scraper opening ring 5 will not hit the drum rotating rod 31 on both sides of the magnetic roller 3. The reserved distance between the drum rotating rod 31 and the scraper mounting plate 4 is mainly convenient for the scraper opening ring 5 to be not scraped. When the scraper opening ring 5 is recovered to the side of the inner wall of the scraper mounting plate 4 when not scraping, the scraper opening ring 5 will not affect the rotating drum rotating rod 31, and the scraper opening ring 5 made of insulating material will not be magnetized by the magnetic roller 3, will not absorb iron slag, and will improve the scraping efficiency.

[0023] The front end of the guide connecting rod 70 extends out from the front side of the scraper opening ring 5, and the width of the guide plate opening 41 is greater than the vertical height of the guide plate 7. The setting of the guide connecting rod 70 extending out from the front end of the scraper opening ring 5 mainly ensures that the scraper opening ring 5 can fall into the guide connecting rod 70 when the scraper opening ring 5 is scraping from the middle of the magnetic rollers 3 on both sides. The size of the guide plate opening 41 ensures that the guide plate opening 41 will not block the movement of the guide plate 7 when the guide plate 7 moves left and right. When not scraping, the guide plate 7 can be retracted to the side of the outer wall of the scraper mounting plate 4 through the guide plate opening 41.

[0024] The pushing mechanism includes a pushing telescopic box 6 and a pushing rod 50. The pushing telescopic box 6 is provided with a motor chamber 60 and a screw chamber 62 from left to right.

The push rod telescopic box 6 is driven by the telescopic motor 61 to rotate the screw rod 63, and the slider 64 slides left and right on the screw rod 63 according to the rotation direction of the screw rod 63, so that the slider 64 drives the scraper opening ring 5 as a whole to slide left and right on the magnetic roller 3 through the push rod 50 to realize the scraping action.

[0025] The working principle of the present invention is as follows: when in use, the slag is first placed in the slag screening box 1, and then the cam motor 22 is turned on. The cam motor 22 drives the slag screening box 1 to swing left and right as a whole through the cam column 2. The drum motor 33 is turned on to drive the magnetic roller 3 to pass through the slag inside the slag screening box 1 through the drum main shaft 32. When the magnetic roller 3 rolls through the slag in the slag screening box 1, the iron slag in the slag will be adsorbed to the surface by the rolled magnetic roller 3. When the magnetic roller 3 adsorbing the iron slag rotates to the middle of the scraper opening ring 5, the drum motor 33 is turned off, and the telescopic motor 61 is driven to rotate forward. The pushing rod 50 extends out of the pushing telescopic box 6 and drives the scraper opening ring 5 to move from the two ends of the magnetic roller 3 to the middle of the magnetic roller 3. When the scraper opening ring 5 moves in contact with the surface of the magnetic roller 3, the iron slag adsorbed on the surface of the magnetic roller 3 is scraped into the guide extending together with the scraper opening ring 5. The scraper 5 is placed in the slag screening box 1 and is then sucked out of the slag screening box 1. The scraper 5 is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The scraper 5 is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The slag is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The slag is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The slag is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The slag is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The slag is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The slag is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. The slag is then sucked out of the slag screening box 1 and is then sucked out of the slag screening box 1. Example
