[0039] 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.

[0040] Please see Figures 1-4 The present invention provides the following technical solution: a three-roll mill, including a three-roll mill body 1, a feeding slide plate 11 fixed on the three-roll mill body 1 near the grinding roller, and also including: an identification sensor 2, a suction nozzle 3 and a negative pressure mechanism 4.

[0041] Furthermore, by Figure 1 As shown, in this embodiment, the identification sensor 2 is fixed on the frame of the three-roll mill body 1 and faces the upper end of the feeding slide plate 11 to identify metallic magnetic materials. The suction nozzle 3 is located above the feeding slide plate 11 and has the freedom of movement in the horizontal and vertical directions. The negative pressure mechanism 4 is fixed on the frame of the three-roll mill body 1 to create a negative pressure environment. The negative pressure mechanism 4 is connected to the suction nozzle 3 via a hose. With the above scheme, during use, the grinding rollers of the three-roll mill grind the conductive slurry. The ground conductive slurry slides out from the feeding slide plate 11. The identification sensor 2 monitors in real time. Under normal circumstances, no metallic magnetic materials overflow. If the identification sensor 2 detects that metallic magnetic materials are overflowing, the suction nozzle 3 approaches the metallic magnetic materials and uses the negative pressure mechanism 4 to create a negative pressure environment. The metallic magnetic materials are then sucked up and recycled through the suction nozzle 3.

[0042] It should be noted that in actual use, the identification sensor 2 can be a suitable sensor such as a Hall sensor or a laser sensor that can be purchased or customized for real-time monitoring.

[0043] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the negative pressure mechanism 4 includes a negative pressure box 41 and a negative pressure fan 42. The negative pressure box 41 is fixed to the top of the frame of the three-roll mill body 1, and a suction nozzle 411 is fixed on the negative pressure box 41.

The negative pressure fan 42 is fixed to the top of the negative pressure box 41, and the air intake of the negative pressure fan 42 is connected to the negative pressure box 41 by an exhaust pipe 421. With the above scheme, in actual use, when the identification sensor 2 detects the overflow of metallic magnetic material, the negative pressure fan 42 starts. The negative pressure fan 42 draws air from the negative pressure box 41 through the exhaust pipe 421, so that a negative pressure space is formed inside the negative pressure box 41, and the metallic magnetic material is drawn in through the suction nozzle 3 for recycling.

[0044] It should be noted that in actual use, the negative pressure fan 42 operates continuously to create a negative pressure environment, and uses the suction nozzle 3 to draw in metallic magnetic materials until the identification sensor 2 detects that no metallic magnetic materials are overflowing.

[0045] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes: a mesh plate 43, which is fixed inside the negative pressure box 41 and divides the internal space of the negative pressure box 41 into an extraction chamber 44 and a recovery chamber 45. The suction nozzle 411 is connected to the recovery chamber 45, and the exhaust pipe 421 is connected to the extraction chamber 44. With the above solution, the extraction chamber 44 and the recovery chamber 45 are independent of each other during use and are isolated by the mesh plate 43. The mesh plate 43 is used to allow air to pass through, while preventing metallic magnetic materials from entering the extraction chamber 44 and the negative pressure fan 42, thus improving safety.

[0046] Preferably, by Figures 1-3 As shown, this embodiment also includes: a cleaning door 46 and a manual screw 47. One end of the negative pressure box 41 has an opening.

A fixing block 412 is fixed to the outer wall of the negative pressure box 41. The manual screw 47 passes through the fixing plate 462 and is connected to the fixing block 412 by thread engagement. With the above solution, the manual screw 47 can be unscrewed later and the cleaning door 46 can be opened to facilitate the cleaning of the recovered metallic magnetic material in the recovery chamber 45.

[0047] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes a transparent observation window 461, which is embedded in the cleaning door 46. With the above design, the transparent observation window 461 allows for convenient real-time monitoring of the situation inside the recycling bin 45.

[0048] Optionally, by Figure 1 , Figure 2 and Figure 4As shown, this embodiment also includes: a mounting plate 5, an inverted L-shaped movable bracket 6, a vertical cylinder 7, an L-shaped fixed bracket 8, and a horizontal cylinder 9. The suction nozzle 3 is fixed to the bottom surface of the mounting plate 5. The horizontal part of the inverted L-shaped movable bracket 6 is located directly above the mounting plate 5. The vertical cylinder 7 is fixed to the top surface of the horizontal part of the inverted L-shaped movable bracket 6, and the piston rod of the vertical cylinder 7 passes through the horizontal part of the inverted L-shaped movable bracket 6 and is fixedly connected to the mounting plate 5. The L-shaped fixed bracket 8 is fixed to the top of the frame of the three-roll mill body 1. The horizontal cylinder 9 is fixed to the vertical part of the L-shaped fixed bracket 8, and the piston rod of the horizontal cylinder 9 passes through the vertical part of the L-shaped fixed bracket 8 and is fixedly connected to the vertical part of the inverted L-shaped movable bracket 6. With the above scheme, when in use, the horizontal cylinder 9 is activated, and the horizontal cylinder 9 drives the inverted L-shaped movable bracket 6 to move horizontally, so that the suction nozzle 3 moves directly above the metallic magnetic material. Then the vertical cylinder 7 is activated, and the vertical cylinder 7 drives the mounting plate 5 to move downward, so that the suction nozzle 3 is close to the metallic magnetic material.

[0049] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, it also includes: guide posts 51. Two guide posts 51 are symmetrically fixed to the top surface of the mounting plate 5, and the guide posts 51 penetrate the horizontal part of the inverted L-shaped movable bracket 6. After adopting the above solution, the two guide posts 51 are used to guide the mounting plate 5, thereby improving the stability of the mounting plate 5.

[0050] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, it also includes: guide rods 61. Two guide rods 61 are symmetrically fixed on the vertical part of the inverted L-shaped movable bracket 6, and the guide rods 61 pass through the vertical part of the L-shaped fixed bracket 8. After adopting the above solution, the two guide rods 61 are used to guide the inverted L-shaped movable bracket 6, thereby improving the stability of the inverted L-shaped movable bracket 6.

Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0055] Using the identification sensor 2 for real-time monitoring, under normal circumstances there is no leakage of metallic magnetic material. If the identification sensor 2 detects leakage of metallic magnetic material, the horizontal cylinder 9 is activated. The horizontal cylinder 9 drives the inverted L-shaped movable bracket 6 to move horizontally, so that the suction nozzle 3 moves directly above the metallic magnetic material. Then the vertical cylinder 7 is activated, and the vertical cylinder 7 drives the mounting plate 5 to move downward, so that the suction nozzle 3 is close to the metallic magnetic material.

[0056] When the negative pressure fan 42 is started, the negative pressure fan 42 draws air from the negative pressure box 41 through the exhaust pipe 421, so that a negative pressure space is formed inside the negative pressure box 41, and the metal magnetic material is drawn in through the suction nozzle 3 for recycling.

[0057] Later, the manual screw 47 can be unscrewed and the cleaning door 46 can be opened to facilitate the cleaning of the recovered metallic magnetic materials in the recycling bin 45.
