Existing impurity removal devices suffer from low efficiency. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please refer to Figures 1-2 A device for removing impurities from silicon-aluminum low-carbon composite cement raw materials includes an impurity removal support 1, on which a screening device and a magnetic separation device are arranged sequentially from top to bottom;

[0025] The magnetic separation device includes a magnetic separation hopper 2, a first magnetic separation roller 3 is rotatably provided on the left side of the magnetic separation hopper 2, and a second magnetic separation roller 4 is rotatably provided on its right side;

[0026] A material distribution guide block 5 is provided on the support of the first magnetic separation roller 3 and the second magnetic separation roller 4. The material distribution guide block 5 is fixed inside the magnetic separation hopper 2. The bottom of the first magnetic separation roller 3 is attached to the left edge of the magnetic separation hopper 2, and the bottom of the second magnetic separation roller 4 is attached to the right edge of the magnetic separation hopper 2.

[0027] In this embodiment, the raw materials of silicon-aluminum low-carbon composite cement can be screened first to remove large particles in the raw materials, which also facilitates magnetic separation. When the screened raw materials fall into the first magnetic separation roller 3 and the second magnetic separation roller 4 through the discharge funnel 12, the metal impurities in them are adsorbed under the action of the first magnetic separation roller 3 and the second magnetic separation roller 4, achieving rapid separation.

[0028] The material distribution guide block 5 can guide the raw materials discharged from the discharge funnel 12 to the first magnetic separation roller 3 and the second magnetic separation roller 4 respectively, so as to achieve full contact between the raw materials and the magnetic separation rollers, thereby improving the magnetic separation effect.

[0029] A first impurity receiving hopper 6 is provided on the left side of the first magnetic separation roller 3, and a second impurity receiving hopper 7 is provided on the right side of the second magnetic separation roller 4. The left side of the first magnetic separation roller 3 is attached to the feed inlet of the first impurity receiving hopper 6, the bottom of the first impurity receiving hopper 6 is inclined, and a first discharge port 8 is opened on the left side of the first impurity receiving hopper 6. The right side of the second magnetic separation roller 4 is attached to the feed inlet of the second impurity receiving hopper 7, the bottom of the second impurity receiving hopper 7 is inclined, and a second discharge port 9 is opened on the right side of the second impurity receiving hopper 7.

[0030] The screening device includes a screening box 10, with an inlet pipe 11 at the top and a discharge funnel 12 at the bottom, the discharge funnel 12 being located directly above the material distribution guide block 5; a screening screen frame 13 is slidably mounted inside the screening box 10, and a discharge inclined pipe 17 is provided on the left side of the screening screen frame 13, the discharge inclined pipe 17 extending to the outside of the screening box 10 through a discharge opening 18, the discharge opening 18 being opened on the left side of the screening box 10; a screening cylinder 14 is horizontally mounted on the rear side of the screening box 10, and the piston rod of the screening cylinder 14 is fixedly connected to the screening screen frame 13. The screening cylinder 14 is existing technology, and its stroke can be controlled as needed, such as by using a limit switch and a sensor. Therefore, this application provides a specific structure of the screening cylinder 14. During the process of the screening cylinder 14 driving the screening screen frame 13 to move, the screening screen frame 13 is always located below the feed pipe 11 so that the raw material discharged through the feed pipe 11 can fall into the screening screen frame 13 to achieve screening.

[0031] In this embodiment, the screening box 10 can screen the raw materials to remove large particles inside. The large particles after screening can be directly discharged to the outside of the screening box 10 through the discharge inclined pipe 17, and the qualified particles fall into the discharge funnel 12.

[0032] A discharge device is provided at the bottom of the discharge funnel 12.

Two material receiving grooves 16 are symmetrically opened on the discharge block 15. A discharge motor is provided on the front side of the discharge funnel 12 at a position opposite to the discharge block 15. The rotor of the discharge motor is fixedly connected to the discharge block 15.

[0033] In this embodiment, the discharge block 15 is rotated by the discharge motor, which can evenly discharge the screened raw material between the two magnetic separation rollers.

[0034] Working principle: The raw materials to be separated are injected into the screening frame 13 through the feed pipe 11. Under the action of the screening cylinder 14, the screening frame 13 moves back and forth in the screening box 10 to achieve screening. The qualified particles after screening fall into the discharge funnel 12.

[0035] The discharge motor drives the discharge block 15 to rotate, and the receiving trough 16 receives the material in the discharge funnel 12 and discharges it to the material distribution guide block 5. Under the action of the material distribution guide block 5, the material is guided and conveyed to the first magnetic separation roller 3 and the second magnetic separation roller 4 respectively.

[0036] The first magnetic separation roller 3 rotates counterclockwise under the action of the corresponding drive motor, and the second magnetic separation roller 4 rotates clockwise under the action of the corresponding drive motor. Metal impurities in the raw material are adsorbed and fall into the first impurity receiving hopper 6 and the second impurity receiving hopper 7 respectively.

[0037] The sorted raw materials are discharged through magnetic separation hopper 2.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
