[0001] The present invention relates to the field of mineral processing equipment, in particular to a mineral processing device for mineral deposit mining. Background Art

[0002] The ore obtained after mining is mixed ore, which contains a variety of ore materials with different properties. Therefore, it needs to be processed by mineral processing. Mineral processing is the process of screening the mixed ore materials by using the physical and chemical properties of different minerals in the ore. For example, the screening of metal ore and non-metallic ore is to use a magnetic separator to screen the mixed ore materials and separate the metal ore and non-metallic ore.

[0003] Among them, when the existing mineral deposit mining and mineral processing equipment is in use, it is impossible to disperse the miscellaneous minerals in the discharge hopper during the discharge process, which easily leads to the accumulation of miscellaneous minerals, the metal minerals on the surface are adsorbed, and the metal minerals in the center are directly discharged without separation, resulting in poor screening effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a mineral processing device for mining and beneficiation of a mineral deposit.

[0016] The beneficial effects of the present invention are as follows: the feed hopper in the present invention introduces the material between any two adjacent sets of orifice plates, and the rotating cylinder drives the material to rotate in the screening chamber through the orifice plates, wherein the exhaust fan introduces a strong airflow into the air inlet chamber and injects it into the gap between the cylinder and the side wall of the screening chamber through the connecting hole, thereby blowing the material driven by the orifice plate upward, causing the material to tumble under the influence of the strong airflow, so that the working electromagnet can fully adsorb the metal ore in the material on the outer wall of the cylinder between the two adjacent sets of orifice plates. When the metal ore in the material is magnetically fixed on the outer wall of the cylinder, and the cylinder drives the non-metallic ore to move to the discharge port through the orifice plate When the metal ore is adsorbed at the outlet, it will be discharged into the collection box. When the cylinder with metal ore adsorbed between the two adjacent sets of orifice plates rotates to the downstream of the discharge port, the electromagnet is powered off, and the metal ore adsorbed by it will be separated from the cylinder and continued to be pushed by the rotating orifice plates. When the metal ore is pushed to the guide hopper by the two sets of orifice plates, a large amount of material will flow out of the guide hopper to the conveying line. At this time, the electric push rod drives the rubber plate to slide between the two adjacent sets of orifice plates and contact the outer wall of the cylinder. Then, when the cylinder is rotating, the rubber plate can scrape and clean the metal ore that may be adhered to the outer wall of the cylinder to prevent the material from adhering to its surface and not being cleaned well.

DETAILED DESCRIPTION

[0020] Below by embodiment, and in conjunction with the accompanying Figure 1-2 , the technical solution of the present invention is further specifically described.

[0021] A mineral deposit mining and beneficiation device includes a box body 1, and a feed hopper 2 is provided on the top of the box body 1:

[0022] A cylindrical screening chamber 3 is longitudinally provided in the box body 1, wherein the feed hopper 2 is connected to the top of the screening chamber 3, and a cylinder 4 driven by a motor 15 is provided in the screening chamber 3, wherein a plurality of groups of strip-shaped orifice plates 6 are radially provided on the outer wall of the cylinder 4 and abut against the side wall of the screening chamber 3, and a group of arc-shaped electromagnets 7 are provided in the side wall of the cylinder 4 between any two adjacent groups of orifice plates 6;

[0023] The bottom of the box body 1 is provided with a discharge port 8 connected to the screening chamber 3, wherein a guide hopper 9 extending to the outside of the box body 1 is provided on the side wall of the screening chamber 3 downstream of the discharge port 8, and an electric push rod 10 is provided on the top of the opening of the guide hopper 9. The output shaft of the electric push rod 10 is provided with a rubber plate 11 extending between two adjacent groups of orifice plates 6 and abutting against the outer wall of the cylinder 4. The rubber plate 11 is an L-shaped structure, wherein the side wall of the rubber plate 11 is provided with reinforcing ribs;

[0024] An air inlet cavity 12 and an air outlet cavity 13 are provided in the box body 1 upstream of the discharge port 8, and the air outlet cavity 13 is located above the air inlet cavity 12, wherein connecting holes 14 communicating with the air inlet cavity 12 and the air outlet cavity 13 are evenly provided on the side wall of the screening cavity 3, and an air pipe 15 communicating with the air inlet cavity 12 and the air outlet cavity 13 is also provided on the outside of the box body 1, and the outlet end of the air pipe 15 on the air outlet cavity 13 is covered with a dust bag 16.

[0025] like Figure 2 As shown, the cross section of the guide hopper 9 is a trumpet-shaped structure, wherein the smallest opening end of the guide hopper 9 is connected to the screening chamber 3, and a conveying line is provided at the bottom of the guide hopper 9.

[0026] In this embodiment, a receiving cavity for receiving a battery pack is provided in the side wall of the cylinder 4 , wherein the battery pack is connected to the electromagnet 7 via a wire.

[0027] In this embodiment, a collection box is provided at the bottom of the discharge port 8 .

[0028] like Figure 2 As shown, two groups of grinding rollers 17 driven by a motor II are arranged in the feed hopper 2, wherein a guide plate 18 is obliquely arranged on the side wall of the feed hopper 2 above the grinding rollers 17.

[0029] When in use, the material is introduced into the feed hopper 2 and guided by the guide plate 18 to between the two sets of grinding rollers 17 for grinding and crushing for subsequent screening. At this time, the motor I5 drives the cylinder 4 to drive the orifice plate 6 to rotate in the screening chamber 3. The feed hopper 2 introduces the material between any two adjacent sets of orifice plates 6, and the rotating cylinder 4 drives the material to rotate in the screening chamber 3 through the orifice plate 6;

[0030] The exhaust fan introduces a strong airflow into the air inlet chamber 12 and injects it into the gap between the cylinder 4 and the side wall of the screening chamber 3 through the connecting hole 14, thereby blowing the material driven by the orifice plate 6 upward, causing the material to tumble under the influence of the strong airflow, so that the working electromagnet 7 can fully adsorb the metal ore in the material on the outer wall of the cylinder 4 between the two adjacent groups of orifice plates 6. At the same time, the gas flows upward in the screening chamber 3 through the aperture of the side wall of the orifice plate 6, and most of the gas flows to the air outlet chamber 13 and enters its interior through the connecting hole 14, and finally flows into the dust bag 16 to filter the dust that may be contained in the gas;

[0031] When the metal ore in the material is fixed on the outer wall of the cylinder 4 by magnetic attraction, and the cylinder 4 drives the non-metallic ore to move to the discharge port 8 through the orifice plate 6, it will be discharged into the collection box. When the cylinder with metal ore adsorbed between the two adjacent sets of orifice plates 6 rotates to the downstream of the discharge port 8, the electromagnet 7 is powered off, and the metal ore adsorbed by it will separate from the cylinder 4 and continue to be pushed by the rotating orifice plate 6. When the metal ore is pushed to the guide hopper 9 by the two sets of orifice plates 6, a large amount of material will flow out of the guide hopper 9 to the conveying line, such as Figure 2 As shown, at this time, the electric push rod 10 drives the rubber plate 11 to slide between the two adjacent groups of orifice plates 6 and contact the outer wall of the cylinder 4. Then, when the cylinder 4 is rotating, the rubber plate 11 can scrape and clean the metal ore that may adhere to the outer wall of the cylinder 4, preventing the material from adhering to its surface and not being properly cleaned. When the downstream orifice plate 6 rotates to the rubber plate 11, the electric push rod 10 drives the rubber plate 11 to reset to prevent it from affecting the normal rotation of the cylinder 4 and the orifice plate 6.

[0032] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
