Description

Technical Field

[0001] This utility model relates to the field of mineral powder impurity removal devices, and in particular to an impurity removal device for mineral powder processing. Background Technology

[0002] The impurity removal device for mineral powder processing is the core pretreatment equipment in mineral powder production. It is mainly used to remove physical, chemical, and weakly magnetic impurities from mineral powder raw materials, ensuring product quality in subsequent grinding, forming, and application stages. It is applied in the fields of metal and non-metal mineral processing. In actual production, this device connects the mineral powder crushing and grinding processes. By processing coarse or semi-fine mineral powder, it can prevent impurities from damaging the equipment and affecting the purity of the mineral powder, and reduce subsequent maintenance costs. It is a key piece of equipment to ensure the quality and efficiency of mineral powder processing.

[0003] The existing impurity removal device for mineral powder processing consists of four main systems: a feeding system, a grading and impurity removal system, an impurity collection system, and a discharge system. The mineral powder raw material enters the device through the feeding hopper, and the impurity removal is completed by the screening and magnetic separation components in the impurity removal system. The discharge system is an inclined filter screen.

[0004] While existing impurity removal devices for mineral powder processing can meet basic requirements, their magnetic separation components have limited adsorption capacity for ferrous impurities, making it difficult to completely capture fine particles. Residual impurities affect the purity of the mineral powder and can easily damage the equipment. The screening system is not well-suited for larger impurities, which can easily get stuck on the screen, reducing efficiency, interrupting production, and potentially causing subsequent equipment failures.

[0005] Therefore, a purification device for mineral powder processing is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a mineral powder processing impurity removal device, which aims to improve the problems of existing magnetic separation components having difficulty in completely capturing fine iron impurities, and screening systems easily getting stuck with larger impurities, affecting the purity of mineral powder, damaging equipment, and reducing efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a mineral powder processing impurity removal device, comprising a support frame, two fixed plates fixedly connected to the outside of the support frame, a receiving box fixedly connected inside the fixed plates, a screen box fixedly connected to the top of the receiving box, a roller box fixedly connected to the top of the screen box, a funnel fixedly connected to the top of the roller box, a screening mechanism provided inside the screen box, the screening mechanism being used to screen out particulate impurities inside the mineral powder to avoid impurity residue affecting subsequent processes and product purity, and an impurity removal mechanism provided inside the funnel to remove excess impurities contained inside the mineral powder to reduce the adverse effects of impurities on subsequent mineral powder processing or product quality; The screening mechanism includes a base, which is fixedly connected to the top of the fixed plate. A power motor is fixedly connected to the top of the base, and a turntable is rotatably connected to the top of the base. A connecting block is fixedly connected to the outside of the turntable, and a rocker arm is fixedly connected to the inside of the connecting block. A push rod is rotatably connected to the side of the rocker arm away from the connecting block. A bracket is fixedly connected to the top of the base, and a filter screen is fixedly connected to the side of the push rod near the screen box.

[0008] As a further description of the above technical solution: a guide plate is fixedly connected to the side of the filter screen away from the push rod, and a waste bin is provided at the bottom of the guide plate.

[0009] As a further description of the above technical solution: the receiving box has a drawer that is slidably connected inside, and the drawer has a handle that is fixedly connected to the outside.

[0010] As a further description of the above technical solution: the push rod is slidably connected inside the bracket, and the filter screen is slidably connected to the inner bottom of the screen box.

[0011] As a further description of the above technical solution: the waste bin is fixedly connected to the outside of the screen box, the output end of the power motor is fixedly connected to the inside of the turntable, and the receiving bin is fixedly connected to the inside of the support frame.

[0012] As a further description of the above technical solution: the impurity removal mechanism includes two connecting plates, which are slidably connected inside the funnel. Several distributing plates are slidably connected between the two connecting plates. Magnets are provided on both sides of each distributing plate. A handle is fixedly connected to the top of each connecting plate.

[0013] As a further description of the above technical solution: two roller shafts are rotatably connected inside the roller box, and a drive motor is fixedly connected to the outside of the roller box.

[0014] As a further description of the above technical solution: the output end of the drive motor is fixedly connected inside the roller shaft, and the drive motor is fixedly connected to the top of the fixed plate.

[0015] This utility model has the following beneficial effects: 1. Mineral powder enters the roller box through the funnel. The two rollers inside the roller box crush and break up the lumps before entering the screen box. At the same time, the power motor on the base starts and drives the turntable to rotate. The turntable drives the rocker arm to swing through the connecting block, which in turn pulls the push rod. Under the limit guidance of the bracket, the push rod drives the filter screen to slide back and forth at the bottom of the screen box. The inclined filter screen separates the mineral powder from the mesh by vibration. The pure mineral powder falls into the receiving box and is received by the drawer. The particulate impurities are pushed to the guide plate through the filter screen and finally fall into the waste box outside the screen box, completing the screening and impurity removal. The support frame and the fixed plate ensure the overall stability of the device.

[0016] 2. The mineral powder first enters the funnel. Inside the funnel, two slidingly connected plates are equipped with several distribution plates. The distribution plates divert the mineral powder to increase its contact area with the magnetic plates on both sides. The magnetic plates adsorb ferrous impurities to achieve preliminary separation. When cleaning is required, the operator pulls the connecting plate by the handle to remove the distribution plate from the funnel for maintenance. The iron-free mineral powder enters the roller box. The drive motor at the top of the fixed plate starts, and the output end drives the two rollers inside the roller box to rotate. The rollers crush the mineral powder to break up the clumps and expose the internal impurities. The drive motor is fixed to the fixed plate to prevent vibration and displacement, ensuring stable roller speed and consistent crushing effect, thus completing the separation of iron and impurities and the crushing of clumps in the mineral powder.

[0019] 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.

[0020] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a mineral powder processing impurity removal device, including a support frame 1. The support frame 1 provides a stable foundation for the entire device, preventing displacement or tipping due to vibration during operation. Two fixing plates 12 are fixedly connected to the outside of the support frame 1. The fixing plates 12 are used to fix the receiving box 4 and the drive motor 7, forming the overall installation frame of the device. The receiving box 4 is fixedly connected inside the fixing plates 12. The receiving box 4 is used to temporarily store the purified mineral powder after impurity removal, preventing the mineral powder from scattering directly. A screen box 5 is fixedly connected to the top of the receiving box 4. The screen box 5 is an important component for separating particulate impurities from the mineral powder. A roller box 3 is fixedly connected to the top of the screen box 5. Roller box 3 protects roller shaft 8 from external interference. A funnel 2 is fixedly connected to the top of roller box 3. The funnel 2 is used to guide the mineral powder to be removed into the device in an orderly manner, reducing the loss and spillage of mineral powder during feeding. The screen box 5 is equipped with a screening mechanism, which is used to screen out particulate impurities inside the mineral powder to avoid impurity residue affecting subsequent processes and product purity. The reciprocating motion of filter screen 13 removes particulate impurities and improves the purity of mineral powder. The funnel 2 is equipped with a removal mechanism, which removes excess impurities contained in the mineral powder to reduce the adverse effects of impurities on subsequent mineral powder processing or product quality. By pre-adsorbing ferrous impurities, the screening burden is reduced and the overall removal efficiency is improved. The screening mechanism includes a base 9, which is fixedly connected to the top of a fixed plate 12. The base 9 provides a stable mounting platform for the power motor 18 and the turntable 24 screening components, ensuring that the positions of each component are fixed. The power motor 18 is fixedly connected to the top of the base 9, providing continuous power for the rotation of the turntable 24. The turntable 24 is rotatably connected to the top of the base 9. The turntable 24 transmits power to the rocker arm 15 through rotation, triggering the reciprocating motion of the screening mechanism. A connecting block 17 is fixedly connected to the outside of the turntable 24, transmitting the rotational motion of the turntable 24 to the rocker arm 15. The rocker arm 15 is fixedly connected to the inside of the connecting block 17, transmitting the rotational motion of the turntable 24 to the rocker arm 15. The circular motion of disc 24 is converted into its own oscillating motion, which in turn drives push rod 16 to perform linear reciprocating motion. The push rod 16 is rotatably connected to the side of rocker arm 15 away from connecting block 17. A bracket 19 is fixedly connected to the top of base 9. The bracket 19 limits and guides push rod 16 to ensure that push rod 16 slides in a fixed direction and avoids movement deviation affecting the screening effect. A filter screen 13 is fixedly connected to the side of push rod 16 near screen box 5. Push rod 16 drives filter screen 13 to perform back-and-forth reciprocating motion in screen box 5. The vibration achieves the separation of mineral powder and impurities. Filter screen 13 is inclined and utilizes the difference in mesh size to allow pure mineral powder to fall into collection box 4, while leaving particulate impurities on the screen surface and allowing them to pass through. The filter screen 13 rolls into the waste bin 6. A guide plate 14 is fixedly connected to the side of the filter screen 13 away from the push rod 16. The guide plate 14 smoothly guides the impurities on the screen surface to the waste bin 6, preventing impurities from accumulating in the screen box 5. The waste bin 6 is set at the bottom of the guide plate 14. The waste bin 6 collects impurities in a centralized manner, realizing the classification and storage of mineral powder and impurities, which is convenient for subsequent cleaning. A drawer 10 is slidably connected inside the receiving box 4. A handle 11 is fixedly connected to the outside of the drawer 10. The drawer 10 receives the pure mineral powder in the receiving box 4. The handle 11 makes it easy for operators to pull out the drawer 10 to take out and put in mineral powder, improving the convenience of operation. The push rod 16 is slidably connected to the inside of the bracket 19. The filter screen 13 is slidably connected to the bottom of the screen box 5. The sliding cooperation between the push rod 16 and the bracket 19 ensures the stability of the reciprocating motion. The sliding of the filter screen 13 and the screen box 5 ensures that the screening range covers the entire screen surface. The waste bin 6 is fixedly connected to the outside of the screen box 5. The fixed installation of the waste bin 6 prevents displacement during impurity collection. The power motor 18 drives the turntable 24 through the output end to realize the power transmission. The output end of the power motor 18 is fixedly connected to the inside of the turntable 24. The receiving box 4 is fixedly connected to the inside of the support frame 1 to improve the installation stability of the receiving box 4 and prevent the receiving box 4 from shifting due to the increase in the weight of the mineral powder it bears or the vibration of the device, thus ensuring the reliability of the mineral powder collection process.

[0021] Reference Figure 2 , Figure 5The impurity removal mechanism includes two connecting plates 23, which are slidably connected inside the funnel 2. The connecting plates 23 are used to install the distribution plates 20. The slidable connection facilitates the removal of the distribution plates 20 as a whole to clean the adsorbed iron impurities. Several distribution plates 20 are slidably connected between the two connecting plates 23. The distribution plates 20 divert the mineral powder in the funnel 2, increasing the contact area between the mineral powder and the magnetic plates 21, thus improving the iron impurity adsorption efficiency. Magnetic plates 21 are provided on both sides of the distribution plates 20. The magnetic plates 21 adsorb the iron impurities in the mineral powder through magnetism, achieving preliminary separation of iron impurities from the mineral powder. A handle 22 is fixedly connected to the top of the connecting plates 23, providing a handle for the operator. The connecting plate 23 is conveniently pulled to remove the material distribution plate 20 for cleaning or maintenance. The roller box 3 has two rotating rollers 8 inside. The rollers 8 crush the mineral powder entering from the funnel 2 by rotating, breaking up the mineral powder clumps and exposing the impurities wrapped in the clumps. The roller box 3 is fixedly connected to the outside of the roller box 3. The drive motor 7 provides rotational power to the rollers 8, driving the rollers 8 to rotate stably. The output end of the drive motor 7 is fixedly connected to the inside of the rollers 8. The drive motor 7 is fixedly connected to the top of the fixed plate 12. The drive motor 7 is fixed on the fixed plate 12 to prevent displacement due to vibration during operation, ensuring the stable rotation speed of the rollers 8 and ensuring consistent crushing effect.

[0022] Working principle: Mineral powder enters the roller box 3 through the funnel 2. The two rollers 8 inside the roller box 3 crush and break up the lumps before entering the screen box 5. At the same time, the power motor 18 on the base 9 starts and drives the turntable 24 to rotate. The turntable 24 drives the rocker arm 15 to swing through the connecting block 17, which in turn pulls the push rod 16. Under the limit and guidance of the bracket 19, the push rod 16 drives the filter screen 13 to slide back and forth at the bottom of the screen box 5. The inclined filter screen 13 separates the mineral powder from the mesh by vibration. The pure mineral powder falls into the receiving box 4 and is received by the drawer 10. The particulate impurities are pushed to the guide plate 14 through the filter screen 13 and finally fall into the waste box 6 outside the screen box 5, completing the screening and impurity removal. The support frame 1 and the fixing plate 12 ensure the overall stability of the device.

[0023] The mineral powder first enters the funnel 2. Inside the funnel 2, two slidingly connected connecting plates 23 are equipped with several distribution plates 20. The distribution plates 20 divert the mineral powder to increase its contact area with the magnetic plates 21 on both sides of the distribution plate 20. The magnetic plates 21 adsorb ferrous impurities to achieve preliminary separation. When cleaning is required, the operator pulls the connecting plate 23 through the handle 22 to remove the distribution plate 20 from the funnel 2 for maintenance. The iron-free mineral powder enters the roller box 3. The drive motor 7 on the top of the fixed plate 12 starts, and the output end drives the two roller shafts 8 inside the roller box 3 to rotate. The roller shafts 8 crush the mineral powder to break up the clumps and expose the internal impurities. The drive motor 7 is fixed to the fixed plate 12 to prevent vibration and displacement, ensuring that the speed of the roller shafts 8 is stable and the crushing effect is consistent, thus completing the separation of iron and impurities and the crushing of clumps in the mineral powder.
