[0037] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0038] like Figure 1-5 As shown, a raw material impurity removal device proposed in this embodiment includes a housing 1, and also includes:

[0039] The screen 2 is fixed inside the casing 1;

[0040] The knocking structure 9 is arranged inside the housing 1 and is used to clean the screen 2;

[0041] A discharge port 3 is fixed on one side of the casing 1;

[0042] A chip discharge port 10 is fixed at the bottom end of the casing 1, and an electromagnetic vibrator 12 is fixed to one side of the bottom end of the casing 1;

[0043] The support spring 4 is fixed on both sides of the housing 1, and a support seat 5 is fixed at the bottom end of the support spring 4;

[0044] The hopper 7 is fixed to one side of the top of the support base 5, and an electric telescopic rod 11 is fixed inside the top of the hopper 7, and a partition 8 is installed at the movable end of the electric telescopic rod 11;

[0045] The separation structure 6 is arranged on one side of the bottom end of the hopper 7, wherein the separation structure 6 includes a guide shell 601 fixed at the bottom end of the hopper 7, a rotating frame 606 rotatably connected to the inside of the guide shell 601, a strong magnetic block 607 fixed to the outside of the rotating frame 606, a motor 602 installed on one side of the guide shell 601 and the rotating end is connected to the rotating frame 606, and a collecting component arranged at the bottom end of the guide shell 601.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the collecting assembly includes a guide plate 605 fixed at the bottom end of the guide shell 601, a fixing frame 604 fixed at the top of one side of the casing 1, and a collecting tank 603 installed inside the fixing frame 604, a snap-fit ​​structure is formed between the collecting tank 603 and the fixing frame 604, and the fixing frame 604 and the casing 1 are welded into an integrated structure, three groups of strong magnetic blocks 607 are arranged on the outside of the rotating frame 606, and the strong magnetic blocks 607 are distributed in a ring shape with equal spacing on the outside of the collecting tank 603, The magnetic force of the strong magnetic block 607 attracts the metal debris, making it close to the surface of the guide shell 601. At the same time, the motor 602 drives the rotating frame 606 to rotate, so that the strong magnetic block 607 moves downward along with the rotation of the rotating frame 606, and the metal debris is moved to the bottom of the guide shell 601. At the same time, the raw materials are thrown into the interior of the casing 1 along the curved surface of the guide shell 601. The guide plate 605 blocks the metal debris from moving along with the magnetic force of the strong magnetic block 607, so that the metal debris is affected by inertia and falls into the interior of the collecting tank 603 along the curved surface of the guide plate 605.

[0047] like Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the knocking structure 9 includes a support plate 902 fixed inside the casing 1, a connecting spring 903 fixed at the top of the support plate 902, a rubber ball 904 fixed at the top of the connecting spring 903, and a limiting groove 901 fixed at the bottom of the screen 2. Several groups of rubber balls 904 are arranged at the bottom of the screen 2, and several groups of rubber balls 904 are evenly spaced and distributed at the bottom of the screen 2. The casing 1 is driven to vibrate by the electromagnetic vibrator 12, so that the casing 1 drives the connecting spring 903 and the rubber ball 904 to shake through the support plate 902. At the same time, the rubber ball 904 continuously knocks the screen 2 through the limiting groove 901, so that the material stuck or stuck between the screen holes of the screen 2 is thrown up and falls.

[0048] Specifically, when the raw material impurity removal device is in use: the raw material is poured into the interior of the hopper 7, so that the raw material slides downward along the inclined surface of the hopper 7 and enters the interior of the casing 1, the partition 8 is driven to move by the electric telescopic rod 11, and the falling speed of the raw material is adjusted. At the same time, the separation structure 6 cleans the metal materials in the raw material, and the electromagnetic vibrator 12 is started to drive the casing 1 to vibrate, so that the raw material moves on the surface of the screen 2 for screening, and the raw material and impurities are discharged through the discharge port 3 and the chip discharge port 10 respectively, and the raw material blocking the holes of the screen 2 is cleaned by the knocking structure 9.

[0049] When the raw material moves to the top of the guide shell 601, the magnetic force of the strong magnetic block 607 absorbs the metal debris, so that the metal debris is closely attached to the surface of the guide shell 601. At the same time, the motor 602 drives the rotating frame 606 to rotate, so that the strong magnetic block 607 moves downward with the rotation of the rotating frame 606, and the metal debris is moved to the bottom of the guide shell 601. At the same time, the raw material is thrown into the interior of the casing 1 along the curved surface of the guide shell 601, and the guide plate 605 blocks the metal debris from moving with the magnetic force of the strong magnetic block 607, so that the metal debris falls into the interior of the collecting tank 603 along the curved surface of the guide plate 605 under the influence of inertia.

[0050] The casing 1 is driven to vibrate by the electromagnetic vibrator 12, so that the casing 1 drives the connecting spring 903 and the rubber ball 904 to shake through the support plate 902. At the same time, the rubber ball 904 continuously knocks the screen 2 through the limiting groove 901, so that the materials stuck or stuck between the screen holes of the screen 2 are thrown up and dropped, and the screen 2 is cleaned.

[0051] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
