Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic separator technology, specifically to a mineral processing device for metal ore beneficiation. Background Technology
[0002] Magnetic separators are used to remove iron powder and other pollutants from powdery materials. They are widely used in resource recycling, timber industry, mining, kiln industry, chemical industry, food industry and other factories. They are suitable for wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore, and ilmenite with a particle size of less than 3mm. They are also used for iron removal in materials such as coal, non-metallic minerals, and building materials. They are one of the most widely used and versatile machines in the industry.
[0003] In current magnetic separators, ore is fed into the separator through the inlet. When the separator is working, the magnetic roller inside the servo motor rotates, evenly adsorbing the metal ore onto the outer wall of the magnetic roller. Since the magnetic roller is composed of multiple electromagnets, after screening, the external power supply to the magnetic roller is disconnected, and the ore on the outer wall of the magnetic roller is discharged from the outlet, completing the screening of the ore.
[0004] In traditional magnetic separators, ore is added into the separator, and after screening the metal ore, it is discharged out through the discharge port. Since the magnetic separator is not equipped with a dust removal device, a large amount of smoke and dust is generated after the ore is screened and discharged. Workers inhale the smoke and dust, which affects their health and pollutes the surrounding environment. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a metal ore beneficiation device that solves the problem of traditional magnetic separators where, during operation, ore is added into the separator, and after screening, the ore is discharged through the discharge port. However, because the magnetic separator lacks a dust removal device, a large amount of smoke and dust is generated after the ore is screened and discharged. This smoke and dust is inhaled by workers, affecting their health and polluting the surrounding environment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal ore beneficiation device, comprising a dust collection box, wherein the inner wall of the dust collection box is provided with a dust removal device, the dust removal device comprising: a vacuum pump installed on the inner wall of the dust collection box; a filter screen installed on the inner wall of the dust collection box; an air inlet pipe, one end of which is connected to the inner wall of the dust collection box; an ash storage tank movably connected to the inner wall of the dust collection box; and a collection port connected to the other end of the air inlet pipe; wherein, when the vacuum pump is working, external air along with dust is drawn into the dust collection box through the air inlet pipe and the collection port, the filter screen filters the dust in the air, and the dust falls into the ash storage tank.
[0007] Preferably, a magnetic separator is installed on the outer wall of the dust collector, and a discharge device is installed on the inner wall of the magnetic separator. The discharge device includes: two limiting rods, both installed on the outer wall of the magnetic separator; a sliding frame movably connected to the outer walls of the two limiting rods; a feeding plate installed on the inner wall of the sliding frame; and a lead screw threadedly connected to the inner wall of the sliding frame and rotatably connected to the inner wall of the magnetic separator via a bearing. The feeding plate facilitates the discharge of ore, and the position of the feeding plate is adjusted by the sliding frame when the lead screw rotates.

[0010] Preferably, the limiting part includes: a roller, which fits against the outer wall of the base plate; a side plate, which is rotatably connected to the outer wall of the roller via a pin and fixed to the top of the magnetic separator; wherein the side plate limits the position of the base plate through the roller. The beneficial effects of this utility model are as follows: This utility model provides a metal ore beneficiation device. It has the following beneficial effects: In this metal ore beneficiation device, the servo motor drives the magnetic separation roller to rotate, and the magnetic separation roller screens the ore. The dust generated during the magnetic separation process is adsorbed by the dust removal device, so the smoke and dust will not be emitted into the surrounding environment, causing no environmental pollution. At the same time, the smoke and dust will not be inhaled into the body, so it will not affect the health of the workers.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0018] In traditional magnetic separators, ore is added into the separator, and after screening the metal ore, it is discharged out through the discharge port. Since the magnetic separator is not equipped with a dust removal device, a large amount of smoke and dust is generated after the ore is screened and discharged. Workers inhale the smoke and dust, which affects their health and pollutes the surrounding environment.
[0019] In view of this, the present invention provides a metal ore beneficiation device. When the servo motor is working, it drives the magnetic separation roller to rotate. The magnetic separation roller screens the ore. The dust generated during the magnetic separation process is adsorbed by the dust removal device. The smoke and dust will not be emitted into the surrounding environment and will not cause environmental pollution. At the same time, the smoke and dust will not be inhaled into the body and will not affect the health of the workers.
[0020] Example 1: By Figures 1 to 4It is known that a metal ore beneficiation device includes a dust collection box 1, and a dust collection device 2 is provided on the inner wall of the dust collection box 1. The dust collection device 2 includes: a vacuum pump 21 installed on the inner wall of the dust collection box 1; a filter screen 22 installed on the inner wall of the dust collection box 1; an air inlet pipe 23, one end of which is connected to the inner wall of the dust collection box 1; an ash storage tank 24 movably connected to the inner wall of the dust collection box 1; and a collection port 25 connected to the other end of the air inlet pipe 23. When the vacuum pump 21 is working, it draws external air along with dust into the dust collection box 1 through the air inlet pipe 23 and the collection port 25. The filter screen 22 filters the dust in the air, and the dust falls into the interior of the ash storage tank 24.
[0021] In the specific implementation process, it is worth noting that the mesh size of the filter screen 22 is not specifically limited, as long as it meets the usage requirements. The model of the vacuum pump 21 is 2X-4G. When the vacuum pump 21 is working, it draws in external air along with dust into the dust collection box 1 through the air inlet pipe 23 and the collection port 25. The filter screen 22 filters the dust in the air, and the dust falls into the dust storage tank 24.
[0022] Specifically, when using this metal ore beneficiation device, the vacuum pump 21 temporarily evacuates the dust collection box 1 to a vacuum state. External air, along with dust, enters the dust collection box 1 through the collection port 25 and the air inlet pipe 23. The filter screen 22 filters out the dust in the air, and the dust falls into the ash storage tank 24. After the ash storage tank 24 is removed, it is convenient to centrally process the dust inside.
[0023] Example 2: From Figure 1 and Figure 2 It is known that a magnetic separator 3 is installed on the outer wall of the dust collector 1, and a discharge device 4 is installed on the inner wall of the magnetic separator 3. The discharge device 4 includes: two limiting rods 41, both installed on the outer wall of the magnetic separator 3; a sliding frame 42, movably connected to the outer wall of the two limiting rods 41; a feeding plate 43, installed on the inner wall of the sliding frame 42; and a lead screw 44, threadedly connected to the inner wall of the sliding frame 42, and rotatably connected to the inner wall of the magnetic separator 3 through a bearing. The feeding plate 43 facilitates the discharge of ore, and the position of the feeding plate 43 is adjusted by the sliding frame 42 when the lead screw 44 rotates.
[0024] In the specific implementation process, it is worth noting that when the lead screw 44 rotates, the position of the feed plate 43 is adjusted through the slide frame 42.
[0025] Furthermore, a storage box 5 is installed on the top of the magnetic separator 3, a feeding pipe 7 is installed on the inner wall of the magnetic separator 3, a magnetic separator roller 8 is rotatably connected to the inner wall of the magnetic separator 3 via a pin, a servo motor 9 is detachably connected to one side of the magnetic separator roller 8, the outer wall of the servo motor 9 is detachably connected to the outer wall of the magnetic separator 3, and a discharge pipe 10 is connected to the bottom of the magnetic separator 3.
[0026] In the specific implementation process, it is worth noting that the ore inside the storage box 5 enters the magnetic separator 3 through the feed pipe 7. When the servo motor 9 is working, it drives the magnetic separator roller 8 to rotate. The screened ore is discharged outward from the discharge pipe 10. The model of the servo motor 9 is SM80-D601930.
[0027] Specifically, based on the above embodiment one, the operator twists the screw 44 to move the feeding plate 43 inside the slide frame 42. The feeding plate 43 presses against the outer wall of the magnetic separation roller 8, which facilitates the discharge of ore from the feeding plate 43. After the feeding plate 43 is worn, its position can be adjusted by the screw 44. The ore inside the storage box 5 enters the magnetic separation box 3 from the feeding pipe 7. When the servo motor 9 is working, it drives the magnetic separation roller 8 to rotate, and the screened ore is discharged from the discharge pipe 10.
[0028] Example 3: From Figure 1 , 2 As shown in section 4, the bottom of the storage box 5 is equipped with a material control device 6: a cylinder 61 installed at the bottom of the storage box 5; a cylinder 62 installed on the outer wall of the cylinder 61; a top plate 63 installed on the top of the cylinder 62 and connected to the bottom of the storage box 5; a bottom plate 64 rotatably connected to the outer wall of the cylinder 62 via a pin; and a limiting part 65 installed on the top of the magnetic separator 3. When the cylinder 61 is working, it drives the cylinder 62 to move, and the bottom plate 64 at the bottom of the cylinder 62 rotates to discharge the ore inside.
[0029] In the specific implementation process, it is worth noting that the cylinder 61 is model SCA2-CB-100B-300-T0H3-DY. The cylinder 61 drives the cylinder 62 to move, and the cylinder 62 drives the ore inside to move. The bottom plate 64 rotates downward under the influence of gravity, and the bottom plate 64 no longer blocks the cylinder 62. The ore inside the cylinder 62 falls into the feed pipe 7.
[0030] Specifically, based on the above embodiment one, when the cylinder 61 is working, it drives the ore inside the cylinder 62 to move. At the same time, the cylinder 62 drives the top plate 63 to block the bottom of the storage box 5. After the cylinder 62 drives the bottom plate 64 to move, the bottom plate 64 rotates under the influence of gravity.
[0031] Example 4: by Figure 1 , 2 As can be seen from section 4, the limiting part 65 includes: a roller 651, which is attached to the outer wall of the base plate 64; a side plate 652, which is rotatably connected to the outer wall of the roller 651 by a pin and is fixed to the top of the magnetic separator 3; wherein, the side plate 652 limits the base plate 64 by the roller 651.
[0032] In the specific implementation process, it is worth noting that the side plate 652 limits the roller 651, and the roller 651 restricts whether the base plate 64 rotates.
[0033] Specifically, the roller 651 no longer restricts the base plate 64. After the base plate 64 rotates, the ore inside the cylinder 62 falls into the feed pipe 7.
