Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling technology, and in particular to an iron removal device for processing recycled aggregates. Background Technology

[0002] With the development of urbanization in my country, the amount of construction waste generated is increasing year by year. In order to reduce the pollution of construction waste to the environment, construction waste is crushed and screened to make recycled aggregate for reuse. Recycled aggregate contains a lot of iron metal impurities. In the processing of recycled aggregate, magnets are used to remove iron metal impurities from the recycled aggregate. Magnets are mostly installed at the discharge port of recycled aggregate production equipment. When recycled aggregate is output, the magnet can adsorb the iron impurities contained in the recycled aggregate and remove them from the recycled aggregate. However, after the amount of iron impurities adsorbed by the magnet reaches a certain amount, the magnet's adsorption force on the iron impurities on the outside weakens. Moreover, under the impact of the output recycled aggregate, the iron impurities are easy to break through the magnet's attraction and fall back into the recycled aggregate, resulting in poor iron removal effect. Therefore, this application proposes an iron removal device for recycled aggregate processing. Utility Model Content

[0020] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0021] Example

[0022] See Figures 1 to 6 This utility model provides a recycled aggregate processing and iron removal device, including a conveyor plate 1, a screen 2, a hopper 3, a collection trough 4, a vibrating frame 5, a material leveling component 6, an iron removal component 9, and a power mechanism 14. The conveyor plate 1 and the screen 2 are fixed on the vibrating frame 5. A conveyor belt can be installed below the screen 2 to transport and collect the screened recycled aggregate. A vibrator can be fixed below the conveyor plate 1 to vibrate the conveyor plate 1 and the screen 2. The hopper 3 is set above the input end of the conveyor plate 1 by a bracket 17. The output port of the hopper 3 is elongated, and its length is slightly less than the length of the conveyor plate 1 to facilitate the dispersion of material. The output end of the conveyor plate 1 is connected to the screen 2. Material is discharged from the hopper 3 onto the conveyor plate 1. Through vibration, the recycled aggregate is transported through the conveyor plate 1 to the screen 2, where the screen 2 can screen the recycled aggregate. The collection trough 4 spans the conveyor plate 1 and is placed on both sides 18 of the vibrating frame 5. Lifting rails 19 are respectively provided on both sides 18 of the vibrating frame 5. The two ends of the iron removal component 9 are slidably connected to the lifting rails 19 on the two sides 18 of the vibrating frame 5. The iron removal component 9 is located on both sides of the collection tank 4. The power mechanism 14 is installed on the vibrating frame 5. The output end of the power mechanism 14 is threadedly connected to the telescopic component 20. The telescopic component 20 is connected to the iron removal component 9 and is also slidably connected to the vibrating frame 5. The iron removal component 9 can adsorb iron impurities contained in the recycled aggregate on the conveying plate 1. The power mechanism 14 pushes the iron removal component 9 to slide along the lifting rails 19 through the telescopic component 20. After the iron removal component 9 slides above the collection tank 4, it releases the adsorbed iron impurities into the collection tank 4. The collection tank 4 is used to collect iron impurities. The telescopic component 20 facilitates the iron removal component 9 to slide along the lifting rails 19 and be positioned above the collection tank 4. The two ends of the material leveling component 6 are rotatably connected to the two sides 18 of the vibrating frame 5 through torsion springs 24. The material leveling component 6 can evenly disperse the recycled aggregate conveyed on the conveying plate 1, effectively avoiding the accumulation of recycled aggregate and affecting iron removal.

[0023] The iron removal assembly 9 includes two electromagnets 10 and two fixing plates 11. An electromagnet 10 is respectively installed on each side of the collection tank 4. When one electromagnet 10 slides above the collection tank 4, the other electromagnet 10 is positioned above the recycled aggregate conveyed by the conveying plate 1, alternately collecting iron impurities adsorbed on the electromagnets 10, thus continuously adsorbing iron impurities contained in the recycled aggregate. The electromagnets 10 are fixed to the fixing plates 11. When the electromagnets 10 are energized, they adsorb iron impurities contained in the recycled aggregate. L-shaped connecting rods 12 are respectively connected to both ends of the fixing plates 11, and the L-shaped connecting rods 12 are connected to a first sliding rod 13. The first sliding rod 13 is slidably connected to the lifting rail 19. The first sliding rod slides on the lifting rail 19, which allows the electromagnet 10 to move along the lifting rail 19 and be lifted upward, so that the electromagnet 10 is above the collection tank 4. When the electromagnet 10 is above the collection tank 4, the electromagnet 10 is de-energized, and the iron impurities adsorbed on the electromagnet 10 fall into the collection tank 4 for collection. The L-shaped connecting rod 12 is connected to the telescopic member 20. When the L-shaped connecting rod 12 is lifted upward along the lifting rail 19 with the first sliding rod 13, the telescopic member 20 extends and maintains the connection with the power mechanism 14, so that the power mechanism 14 continuously pushes the iron removal component 9 to move.

[0024] The telescopic component 20 includes a telescopic rod 21, a connecting plate 22, and a second sliding rod 23. One end of the second sliding rod 23 is slidably connected to the vibration frame 5, and the free end of the second sliding rod 23 is connected to the connecting plate 22. Both ends of the telescopic rod 21 are connected to the connecting plate 22 and the L-shaped connecting rod 12, respectively. The power mechanism 14 includes a motor 15 and a screw 16. The motor 15 is mounted on the vibration frame 5, and the output end of the motor 15 is connected to the screw 16. The screw 16 is threadedly connected to the connecting plate 22. The motor 15 drives the screw 16 to rotate, and the screw 16 is threadedly connected to the connecting plate 22. The connecting plate 22 is connected to the telescopic rod 21, and then the connecting plate 22 pushes the first sliding rod 13 to move along the lifting rail 19, thereby moving the fixed plate 11 and the electromagnet 10. When the first sliding rod 13 slides, it lifts the L-shaped connecting rod 12, the fixed plate 11, and the electromagnet 10. The telescopic rod 21 extends in sync with the L-shaped connecting rod 12.

[0025] The material leveling assembly 6 includes a material leveling plate 7 and several material leveling rods 8. The several material leveling rods 8 are fixed to the bottom of the material leveling plate 7. The two ends of the material leveling plate 7 are respectively connected to the vibrating frame 5 via torsion springs 24. The material leveling rods 8 disperse the recycled aggregate conveyed on the conveying plate 1 and cooperate with the material leveling plate 7 to limit the thickness of the recycled aggregate on the conveying plate 1, thereby avoiding excessive thickness of the conveyed recycled aggregate and maintaining the iron removal effect of the iron removal assembly 9.

[0026] The bottom of the collection tank 4 is provided with two limiting plates 25, which can limit the position of the collection tank 4 and facilitate the removal of the collection tank 4 when a certain amount of iron impurities are collected.

[0027] In use, the hopper 3 discharges recycled aggregate onto the conveyor plate 1 through the output port. Since the conveyor plate 1 and screen 2 are inclined, the recycled aggregate is conveyed from the conveyor plate 1 to one end of the screen 2 as the conveyor plate 1 and screen 2 vibrate. When the recycled aggregate passes through the leveling component 6, the leveling plate 7 and several leveling rods 8 work together to disperse the recycled aggregate and limit its thickness on the conveyor plate 1. When the electromagnet 10 is energized, iron impurities in the recycled aggregate passing below the electromagnet 10 are attracted to it. When iron impurities are attracted to the electromagnet 10 near the screen 2 or near the hopper 3, the iron... When the impurities reach a certain amount, the motor 15 drives the screw 16 to rotate. The screw 16 is threadedly connected to the connecting plate 22. The connecting plate 22 is connected to the telescopic rod 21. The telescopic rod 21 is connected to the L-shaped connecting rod 12. The first sliding rod 13 slides on the lifting rail 19. The L-shaped connecting rod 12 pushes the first sliding rod 13 to slide along the lifting rail 19, lifting the L-shaped connecting rod 12, the fixing plate 11, and the electromagnet 10. The telescopic rod 21 extends to match the lifting of the L-shaped connecting rod 12. The electromagnet 10, which is close to the screen 2 or close to the hopper 3, is located above the collection tank 4. When the electromagnet 10 is de-energized, the iron impurities fall into the collection tank 4.
