[0018] Please see Figures 1-4The present invention provides the following technical solution: it includes an outer shell 1, an mounting plate 11 installed on the inner wall of one side of the outer shell 1, and a connecting plate 2 installed inside the outer shell 1. A plurality of guide plates 21 are provided on one side of the connecting plate 2, and an electromagnet 22 is provided at the bottom of each guide plate 21. A plurality of electric telescopic rods 23 are installed on one side of the mounting plate 11. Both ends of one side of the electromagnet 22 are connected to the output end of the corresponding electric telescopic rod 23 through a bracket. A blower pipe 3 is installed on one side of the connecting plate 2, and a plurality of branch pipes 31 are provided on one side of the blower pipe 3. A driver 12 is installed on the inner wall of one side of the outer shell 1, and a movable plate 13 is connected to the output end of the driver 12. A collection box 4 is provided on one side of the outer shell 1.

[0019] In this embodiment: the external main structure is formed by the outer shell 1, the mounting plate 11, and the connecting plate 2. Several guide plates 21 are arranged on one side of the connecting plate 2, arranged sequentially from top to bottom to guide the raw iron ore, causing it to move from top to bottom. Electromagnets 22 are installed at the bottom of each guide plate 21 to attract the iron ore passing through it. In this embodiment, the electromagnets 22 are connected to an external control component and a power supply via wires. It can control the power supply and de-energization of the electromagnet. Several electric telescopic rods 23 are installed on one side of the mounting plate 11 to drive the electromagnet 22, causing it to slide on the connecting plate 2. This reduces the impact of falling raw materials on the electromagnet 22 when the iron ore is being discharged. Both ends of one side of the electromagnet 22 are connected to the output ends of the corresponding electric telescopic rods 23 via brackets. A blower pipe 3 is installed on one side of the connecting plate 2, and several branch pipes 31 are provided on one side of the blower pipe 3. The blower pipe 3 is connected to the blower equipment, and the blower pipe 3 connects to the branch pipes 31. Pipe 31 blows air onto the top of guide plate 21, blowing light impurities downwards at an angle, thus removing impurities stuck between iron ore particles from guide plate 21. A driver 12 is installed on the inner wall of one side of the outer casing 1, and a movable plate 13 is connected to the output end of driver 12. The driver 12 and movable plate 13 form a component that guides the guide plate 21 located at the lowest end. When discharging impurities and fallen ore, the movable plate 13 opens and closes the channel between connecting plate 2 and outer casing 1, allowing impurities and iron ore to exit from different outlets of outer casing 1. A collection box 4 is provided on one side of outer casing 1 to collect the removed impurities. This allows the new invention to thoroughly clean all non-raw material impurities from iron ore raw materials, ensuring that impurities and iron ore raw materials are discharged from different outlets. During the impurity removal process, a large amount of dust on the surface of the iron ore is cleaned, more accurately distinguishing iron ore raw materials from impurities. It can also pick out ores that resemble iron ore raw materials, resulting in better impurity removal.

[0020] Several guide plates 21 are inclined and arranged sequentially from top to bottom. A side baffle 211 is fixedly connected to one end of the top of the guide plate 21. The inclined arrangement of the guide plates 21 allows the raw ore to move sequentially from top to bottom. During the movement, impurities are removed. The side baffle 211 blocks the raw ore passing over the top of the guide plate 21, preventing it from falling during the sliding process.

[0021] A guide platform 14 is provided at the bottom of the inner cavity of the outer shell 1, and an impurity outlet 15 and an ore outlet 16 are respectively opened on both sides of the outer shell 1. By setting the guide platform 14, the ore raw material falling to the bottom of the inner cavity of the outer shell 1 is guided so that it can be moved out of the interior of the outer shell 1 through the ore outlet 16.

[0022] The top of the collection box 4 is correspondingly set with the impurity outlet 15, and the ore outlet 16 is set at the bottom of one side of the outer shell 1, and the ore outlet 16 is connected to one end of the guide table 14; the impurity outlet 15 is used to discharge impurities, which enter the interior of the collection box 4 and are collected by the collection box 4.

[0023] The top of the outer shell 1 is set as an open structure. The mounting plate 11 is fixedly connected to the inner wall of one side of the outer shell 1, and the mounting plate 11 and the connecting plate 2 are fixedly connected by a connecting bracket. The mounting plate 11 is installed inside the outer shell 1, and the connecting plate 2 and various components are installed and connected through the mounting plate 11, so that the external frame of this new type remains stable.

[0024] Several branch pipes 31 are grouped and set on one side of the air blowing pipe 3, and the branch pipes 31 extend through one side of the connecting plate 2 to the top of the corresponding guide plate 21; each guide plate 21 is provided with several branch pipes 31 at the top to clean the dust on the surface of the iron ore raw material and the impurities stuck between the ore, and move them diagonally downward.

[0025] A number of through slots 221 are provided on one side of the connecting plate 2, and the electromagnet 22 is slidably connected to the corresponding through slot 221. By providing a number of through slots 221 on the connecting plate 2, the electromagnet 22 can be slidably connected to the connecting plate 2, and the electromagnet 22 can be moved under the drive of the electric telescopic rod 23.

[0026] The working principle and usage process of this utility model are as follows: When removing impurities from ore raw materials, the ore raw materials enter from the top of the outer shell 1 and fall to the top of the first guide plate 21. Through several guide plates 21, the ore raw materials are moved sequentially to the bottom of the inner cavity of the outer shell 1. During the movement of the ore raw materials, the electromagnet 22 is located at the bottom of the guide plate 21 and is kept energized. This causes the iron ore passing through the guide plate 21 to be attracted by the electromagnet 22 and remain on the surface of the guide plate 21 until all the surfaces of the guide plates 21 are covered with iron ore, at which point the feeding stops. During this process, non-iron ore stones and impurities continue to move downwards along the guide plates 21. Air is blown to the top of the guide plates 21 through the air pipe 3 and branch pipe 31 to assist in the movement of impurities and non-iron ore stones. The movement simultaneously cleans the dust on the surface of the iron ore. Impurities move along the guide plate 21 to the bottom layer. At this time, the movable plate 13 is located at the connection point of one end of the guide plate 21 at the bottom, so that the impurities enter the inner cavity of the collection box 4 along the movable plate 13. After the impurities are removed, the driver 12 is started to move the movable plate 13 upward, and then the electromagnet 22 is turned off so that it is no longer energized. The electric telescopic rod 23 drives the electromagnet 22 to slide to one side and align with the guide plate 21. The iron ore at the top of the guide plate 21 loses its attraction and rolls down along the guide plate 21. It falls to the top of the guide table 14 through the channel between the guide plate 21 and the inner wall of the outer shell 1. The guide table 14 allows the iron ore raw material to be discharged through the ore outlet 16. The above steps are repeated to remove impurities from the iron ore.
