[0002] The drum type magnetic separator is the main equipment for removing iron-containing impurities from carbon black in the tire recycling production system, and the quality of its recycling effect directly affects the quality of carbon black. Carbon black enters through the upper inlet of the magnetic separator, passes through the high-strength magnetic drum, and is discharged from the carbon black outlet.

Detailed Embodiments

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0039] Embodiment: As Figures 1 to 4 shown, this embodiment provides a drum-type magnetic separator, which includes a box body 1, a fan 2, a magnetic separation drum 3 and a first driver 31; the upper part of the box body 1 has a feed inlet 11, the lower part of the box body 1 has a discharge outlet, a guide plate 12 is arranged below the feed inlet 11, and the guide plate 12 is used to guide the materials falling at the feed inlet 11 to one side inside the box body 1. A impurity hopper 4 and a finished product hopper 5 are arranged below the discharge outlet. The bottom of the impurity hopper 4 has an impurity outlet 41, and the bottom of the finished product hopper 5 has a finished product outlet 51; an air inlet is opened on the side of the box body 1 away from the material falling position; the inlet of the fan 2 is connected to the finished product outlet 51, and the fan 2 is used to form a negative pressure state inside the box body 1; the magnetic separation drum 3 is rotatably installed inside the box body 1, and the magnetic separation drum 3 is used to adsorb iron-containing impurities; the feed inlet 11 is located above the cylindrical side wall of the magnetic separation drum 3, and the discharge outlet is located below the cylindrical side wall of the magnetic separation drum 3; the finished product hopper 5 and the impurity hopper 4 are horizontally distributed in sequence along the rotation direction of the magnetic separation drum 3 below the magnetic separation drum 3; the first driver 31 is installed on the box body 1, the first driver 31 is connected to the magnetic separation drum 3, and the first driver 31 is used to drive the magnetic separation drum 3 to rotate.

[0040] Through the above settings, the drum-type magnetic separator in this embodiment is the main equipment for removing iron-containing impurities from carbon black in the tire recycling and reuse production system, and the quality of its recycling effect directly affects the quality of carbon black. By arranging an air inlet on the side of the box body 1 and connecting the fan 2 to the finished product outlet 51, a negative pressure environment is formed inside the box body 1, reducing the flying of carbon black, not affecting the discharge of iron-containing impurities, and reducing environmental pollution.

[0041] Specifically, the magnetic separation drum 3 has a permanent magnet assembly 32 for adsorbing iron-containing impurities in the material. During operation, the magnetic separation drum 3 rotates and the permanent magnet assembly 32 remains stationary. When the material enters through the feed inlet 11 and falls onto the surface of the magnetic separation drum 3 through the guide plate 12, the material rotates clockwise with the magnetic separation drum 3. When it reaches the surface of the permanent magnet assembly 32, the iron-containing impurities are adsorbed on the surface of the magnetic separation drum 3 and are discharged to the impurity hopper 4 together with the magnetic separation drum 3. The finished product material makes a free fall and enters the finished product hopper 5. Since the material is powder, its fluidity is uneven and it is easy to fly. By setting the air inlet and the fan 2 in cooperation, the material inside the box body 1 does not fly, and the fluidity of the material and the uniformity of the material on the surface of the magnetic separation drum 3 are increased.

[0042] Optionally, the first driver 31 includes a reduction motor 311 and a chain drive mechanism 312. The reduction motor 311 is driven through the chain drive mechanism 312 to drive the magnetic separation drum 3 to rotate.

[0043] In a drum-type magnetic separator according to this embodiment, the air inlet is located at a position close to the feed port 11 or at a position below the middle of the magnetic separation drum 3. Additionally, optionally, the air inlet includes an upper air inlet 13 and a lower air inlet 14. The upper air inlet 13 is located at a position close to the feed port 11, and the lower air inlet 14 is located at a position below the middle of the magnetic separation drum 3. The setting of the upper air inlet 13 prevents the materials in the box body 1 from flying, increases the fluidity of the materials and the uniformity of the materials on the surface of the magnetic separation drum 3, enables the carbon black to move as close as possible to the magnetic separation drum 3, and ensures the magnetic separation effect. The setting of the lower air inlet 14 ensures that the carbon black does not fly into the impurity hopper 4, solves the problem of powder flying during discharging, reduces the loss of carbon black, and does not affect the discharge of iron-containing impurities.
