It is the first step in ore processing and smelting, and one of the most important steps. Mineral powder is the raw material of industrial production, through which high added value can be further generated. Among them, the common mineral powder impurity removal is to separate the magnetic substances in the mineral powder or mineral powder mixture through the impurity removal device.

[0039] The filter assembly 6 is suitable for screening and filtering the mineral powder entering the separation box 1;

[0040] The impurity removal component 7 is suitable for separating magnetic metal impurities in the ore powder after screening and filtration;

[0041] The collecting assembly 8 is suitable for classifying and collecting the ore powder and impurities after screening and separation. When in use, the ore powder to be processed is sent into the separation box 1 through the feeding funnel 2. The ore powder can be vibrated and screened by the set filter assembly 6, so that large particles of impurities can be effectively screened out and collected by the collecting assembly 8, effectively separating the large particles of impurities in the ore powder, and the ore powder after screening can continue to fall; the impurity removal assembly 7 can continuously adsorb the magnetic metal impurities in the ore powder, and due to the The plurality of electromagnetic plates 15 in the impurity removal component 7 for adsorbing magnetic metal impurities perform adsorption work alternately, and can make the magnetic metal impurities adsorbed on the plurality of electromagnetic plates 15 be processed and collected alternately after reaching a certain amount, thereby ensuring the separation and processing quality and efficiency of the magnetic metal impurities in the ore powder, and the impurity removal effect of the electromagnetic plate 15 on the ore powder will not be affected by the adsorption of too many magnetic metal impurities on the electromagnetic plate 15; and the set collection component 8 can classify and collect impurities and processed ore powder, so as to facilitate the subsequent centralized processing of ore powder and impurities by subsequent staff.

[0042] Optionally, the impurity removal component 7 includes a separation baffle 9 fixed between the first baffle 3 and the second baffle 4, two discharge troughs 10 opened on the first baffle 3, a first rotating shaft 11 rotatably connected to the separation box 1, a second rotating shaft 12 rotatably connected to the two discharge troughs 10, two material-delay baffles 13 fixedly sleeved on the first rotating shaft 11, two guide baffles 14 fixedly sleeved on the second rotating shaft 12, a plurality of electromagnetic plates 15 respectively fixed on the two guide baffles 14, and a diversion component 16 arranged on the guide plate 5 and the first baffle 3;

[0044] The two guide baffles 14 are respectively arranged in the two discharge troughs 10;

[0045] The two material retention baffles 13 and the two guide baffles 14 are arranged perpendicular to each other. After the mineral powder is screened through the filter assembly 6, it falls to the impurity removal assembly 7. At this time, the first rotating shaft 11 rotates, so that the material retention baffle 13 on the rear side of the separation baffle 9 is in a horizontal state, thereby preventing the mineral powder from continuing to fall through the material retention baffle 13. The material retention baffle 13 on the front side of the separation baffle 9 is in a vertical state at this time, and the screened mineral powder can fall to the collection assembly 8 and fall on the electromagnetic plate 15 on one of the guide baffles 14.

At this time, the magnetic metal impurities on the electromagnetic plate 15 can fall along the electromagnetic plate 15 and be collected by the collecting assembly 8, while the electromagnetic plate 15 on the other guide baffle 14 can be powered on to separate the ore powder falling to the rear side of the separation baffle 9. The electromagnetic plates 15 on the two separation baffles 9 are used to alternately collect the magnetic metal impurities in the ore powder and alternately process the magnetic metal impurities on the electromagnetic plates 15, which can be continuously processed. The impurities in the ore powder are separated and processed to ensure the separation effect of the impurities in the ore powder; and the electromagnetic plate 15 is in a clean state before collecting the magnetic metal impurities to avoid the single electromagnetic plate 15 adsorbing too much magnetic metal impurities and affecting the adsorption effect, thereby ensuring the separation quality of the magnetic metal impurities in the ore powder; and through the setting of the diversion component 16, when one of the material retention baffles 13 is in a horizontal state and the other material retention baffle 13 is in a vertical state, it can be avoided that a large amount of ore powder falls on the horizontal material retention baffle 13, which affects the subsequent impurity removal effect of the ore powder.

[0048] The filter plate 17 and the guide plate 5 are arranged parallel to each other. When the mineral powder falls into the separation box 1 through the dropping funnel 2 and falls on the obliquely upward end of the filter plate 17, the vibration motor 21 drives the filter plate 17 to vibrate, so that the plurality of sliders 19 slide in the plurality of slide grooves 18 respectively to guide the filter plate 17, and under the elastic force of the plurality of return springs 20, the filter plate 17 can reciprocate and move up and down to vibrate, so that the mineral powder falling on the filter plate 17 can be vibrated and screened, so that larger particles of mineral powder impurities can slide along the inclined direction of the filter plate 17 and be collected by the collecting component 8, and the screened mineral powder can fall to the bottom of the filter plate 17 and be further processed by the impurity removal component 7, and the vibration screening process of the filter plate 17 can ensure the filtering effect of the mineral powder, and prevent the mineral powder from clogging the filter plate 17.

At the same time, the first motor 24 is started to drive the diverter rod 23 to rotate, so that the diverter rod 23 adjusts its position on the guide plate 5. When the other end of the diverter rod 23 is against the rear end inner wall of the separation box 1, the mineral powder can pass through the guide plate 5 falls on the material retention baffle 13 on the front side of the guide baffle 14 to separate the magnetic metal impurities, and prevents the mineral powder from falling on the material retention baffle 13 on the rear side of the guide baffle 14, thereby preventing a large amount of mineral powder from accumulating on the material retention baffle 13 on the rear side of the guide baffle 14 during the collection of the magnetic metal impurities on the rear side of the guide baffle 14, affecting the subsequent rotation of the material retention baffle 13, and at the same time preventing a large amount of mineral powder from being processed by the electromagnetic plate 15 in a short period of time, affecting the collection effect of the electromagnetic plate 15 on the magnetic metal impurities, and when the other end of the diverter rod 23 abuts against the front end inner wall of the separation box 1, it can prevent a large amount of mineral powder from accumulating on the material retention baffle 13 on the front side of the guide baffle 14.

The transmission of the first rotating shaft 11 and the second rotating shaft 12 can be completed by only a single motor, thereby reducing costs.
