[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.
[0025] This utility model embodiment provides a device for removing iron and impurities from pyrolytic coarse carbon black containing steel wire. Figure 1 This is a schematic diagram of the iron and impurity removal equipment for pyrolytic coarse carbon black containing steel wire, according to an embodiment of the present invention. (Reference) Figure 1 , 2 As shown, the equipment for removing iron and impurities from pyrolytic coarse carbon black containing steel wire includes: a dust collector; such as... Figure 3As shown, the magnetic separator 3 includes: a first housing 301, forming a first chamber and having a feed inlet for the magnetic separator 3, the feed inlet of the magnetic separator 3 being connected to the discharge outlet of a dust collector; a first vibration assembly, disposed within the first chamber, including a first feeding plate 302, a first vibration spring 303 connected to the bottom surface of the first feeding plate 302, and a first vibration motor 304 driving the first vibration spring 303 to vibrate; the top surface of the first feeding plate 302 is positioned opposite to the discharge outlet of the dust collector; a first magnetic suction roller 305 is disposed below the discharge outlet of the first feeding plate 302; and a raw material receiving... The raw material collection bin 4 has its inlet connected to the carbon black outlet of the magnetic separator 3; the iron remover 5 includes: a second housing 501 that forms a second chamber and has an inlet for the iron remover 5, the inlet of which is connected to the outlet of the raw material collection bin 4; a second vibration assembly located in the second chamber, including a second feeding plate 502, a second vibration spring 503 connected to the bottom surface of the second feeding plate 502, and a second vibration motor 504 that drives the second vibration spring 503 to vibrate; and a second magnetic roller 505 located below the outlet of the second feeding plate 502.
[0026] The aforementioned iron and impurity removal equipment for pyrolytic coarse carbon black containing steel wire incorporates a dust collector before the magnetic separator 3. This prevents dust leakage from the pyrolytic coarse carbon black and helps avoid the impact of dust on subsequent steel wire separation. Vibration components are installed in both the magnetic separator 3 and the iron separator 5. The vibration springs and motor work together to ensure uniform material distribution on the feeding plate, guaranteeing even coverage and preventing localized over- or under-coverage. This uniform material distribution also allows the magnetic poles to better adsorb ferromagnetic substances mixed in the material, ensuring even distribution and preventing blockages, thereby improving iron removal efficiency and effectiveness. Furthermore, by simultaneously installing the magnetic separator 3 and the iron separator 5, connected by the raw material collection bin 4, with the magnetic separator 3 preceding the iron separator 5, the removal efficiency and effectiveness of steel wire and other metals from the pyrolytic coarse carbon black can be significantly improved.
[0027] like Figure 4 As shown, the first magnetic roller 305 includes a drum 3051 and a permanent magnet 3052 disposed on one side inside the drum 3051. The working principle of the iron separator 5 and the magnetic separator 3 is based on the adsorption effect of the strong magnetic field of the permanent magnet 3052 on ferromagnetic materials. The permanent magnet 3052 is stationary. When the material passes through the iron separator 5, the ferromagnetic materials in it are attracted by the strong magnetic field to the outer drum 3051 disc of the iron separator 5. As the outer drum 3051 disc rotates continuously, these materials are carried to the iron unloading area for removal.

The discharge port of the cyclone dust collector 1 is connected to the feed port of the magnetic separator 3, and the air outlet of the cyclone dust collector 1 is connected to the air inlet of the bag filter dust collector 2; the discharge port of the bag filter dust collector 2 is connected to the feed port of the raw material collection silo 4. By setting up the cyclone dust collector 1 and the bag filter dust collector 2, their connection positions and relationships are defined, ensuring a high dust removal and separation effect. The feed port of the cyclone dust collector 1 is connected to the discharge port of the carbon black conveying pipeline, and the air outlet of the cyclone dust collector 1 is connected to the air inlet of the bag filter dust collector 2 on the top of the silo.

Three sets of permanent magnet suction rollers are installed inside the first housing 301. The steel wire in the coarse carbon black is attracted by the three sets of permanent magnet suction rollers, and the separated steel wire is discharged from the steel wire outlet, while the separated coarse carbon black is discharged from the carbon black outlet. The discharged steel wire enters the steel wire conveying pipe and then into the steel wire turnover box, whose feed inlet is located on the upper right side of the box body.

The discharge port of the raw material conveying screw conveyor 6 is connected to the bucket elevator 7. The discharge port of the bucket elevator 7 is connected to the inlet of the iron separator 5.

A crude carbon black buffer silo 11 is located at the bottom of the high-temperature solid-vapor separation chamber 12. The discharge port of the crude carbon black buffer silo 11 is connected to the inlet of the self-sealing gas-blocking screw conveyor 10. The self-sealing gas-blocking screw conveyor 10 uses chain drive, and the drive unit is located on its lower right side. The discharge port of the self-sealing gas-blocking screw conveyor 10 is connected to the inlet of the primary circulating water-cooled screw conveyor 9. A screw shaft with screw blades is installed inside the cylinder of the primary circulating water-cooled screw conveyor 9. Under the action of the drive unit, the incoming material is moved towards the discharge port. The drive unit is located on the right side of the screw cylinder.
[0034] The discharge port of the primary circulating water-cooled screw conveyor 9 is connected to the feed port of the secondary circulating water-cooled screw conveyor 9.

[0036] The working process of the above-mentioned pyrolytic coarse carbon black iron and impurity removal equipment containing steel wire is as follows:
[0037] Pyrolytic coarse carbon black containing impurities such as steel wire is separated into powder and other impurities by a dust collector, and then enters a magnetic separator 3. Under the action of the first vibration component, the material is evenly distributed. Then, it passes through a three-stage magnetic suction roller to separate the steel wire. The material after separating the steel wire enters the raw material collection bin 4, is mixed, and then enters the iron separator 5. Under the action of the second vibration component, the material is evenly distributed, and then passes through a two-stage magnetic suction roller to further separate iron and other metal impurities.
