Description

Technical Field

[0001] This utility model relates to the field of wollastonite powder production technology, specifically to a wollastonite powder impurity removal and screening device. Background Technology

[0002] Wollastonite powder is an inorganic non-metallic mineral powder produced from natural wollastonite ore through crushing, grinding, and other processes. It possesses excellent insulation, thermal stability, and mechanical strength, and is widely used in various industrial fields such as coatings, plastics, rubber, ceramics, and metallurgy. In the production and processing of wollastonite powder, impurity removal and screening are necessary to ensure product quality. Currently, the industry commonly uses screens and sieve plates to screen wollastonite powder. These devices primarily separate materials based on differences in particle size, effectively removing impurities with particle sizes different from wollastonite powder, and are practical in particle size screening.

[0003] However, in actual production, wollastonite ore is often associated with magnetic minerals such as magnetite and hematite during its formation, resulting in a certain amount of magnetic impurities in the wollastonite powder. These magnetic impurities have particle sizes similar to those of the wollastonite powder, and conventional sieves and screens, relying solely on physical size for screening, cannot identify and separate these magnetic impurities. The presence of magnetic impurities in the wollastonite powder reduces its quality, affecting its application in fields such as coatings, plastics, and rubber, where high purity is required. To remove magnetic impurities from wollastonite powder and ensure product quality, we propose a wollastonite powder impurity removal and screening device. Utility Model Content

[0027] 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.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a wollastonite powder impurity removal and screening device, including a workbench 1, two sets of mounting plates 10 fixedly connected to the top of the workbench 1, a rotating cylinder 2 rotatably installed between the two sets of mounting plates 10, a feed inlet 8 fixedly connected to the left mounting plate 10, a mounting box 3 fixedly connected to the right mounting plate 10, a discharge port connected to the mounting box 3 on the right mounting plate 10, a dirt removal component for removing magnetic impurities installed on the rotating cylinder 2, a screening component for screening wollastonite powder installed on the mounting box 3, and a drive component for driving the dirt removal component and the screening component to operate on the mounting plate 10.

[0029] The impurity removal assembly includes a magnetic roller 18, which is rotatably mounted on a mounting plate 10. Several sets of rotating plates 20 are fixedly connected to the inner wall of the rotating cylinder 2. Two sets of first guide plates 17 and a baffle 25 are fixedly connected between the two sets of mounting plates 10. The first guide plates 17 are inclined. A mounting cover 23 is fixedly connected between the two sets of mounting plates 10. Several sets of second guide plates 19 are fixedly connected to the side of the baffle 25 near the mounting cover 23. A scraping mechanism for scraping off magnetic impurities is installed on the mounting cover 23. A conveying mechanism for conveying magnetic impurities is installed on the rotating cylinder 2.

[0030] In use, wollastonite powder is poured into the rotating drum 2 through the feed port 8. Under the action of the drive component, the rotating drum 2 and the magnetic roller 18 rotate, which drives the rotating plate 20 to rotate. The wollastonite powder accumulated at the bottom of the rotating drum 2 is carried by the rotating plate 20 to fall above the first guide plate 17. Under the guidance of the first guide plate 17, the wollastonite powder falls onto the magnetic roller 18. The magnetic impurities are adsorbed on the surface of the magnetic roller 18. The wollastonite powder falls between the mounting cover 23 and the baffle 25 under the action of gravity. The wollastonite powder is guided by the second guide plate 19 to move a distance to the right when falling. The magnetic impurities adsorbed on the magnetic roller 18 are scraped off by the scraping mechanism and conveyed out of the rotating drum 2 by the conveying mechanism. As the rotating drum 2 and the magnetic roller 18 continue to rotate, the wollastonite powder moves to the right until it enters the installation box 3 from the discharge port at the far right. It is then screened by the screening component. During this process, the wollastonite powder comes into contact with the magnetic roller 18 multiple times, which can effectively remove magnetic impurities from the wollastonite powder and ensure product quality.

[0031] The scraping mechanism includes several sets of connecting frames 29, which are fixedly connected to the inner wall of the mounting cover 23. A sliding cover 28 is fixedly connected to the side of the connecting frame 29 away from the mounting cover 23. A scraping block 26 is slidably installed on the inner wall of the sliding cover 28. Several sets of first springs 27 are fixedly connected to the bottom of the scraping block 26. The bottom of the first springs 27 is fixedly connected to the bottom of the inner cavity of the sliding cover 28. The top of the scraping block 26 abuts against the bottom of the magnetic roller 18.

[0032] The conveying mechanism includes a rotating rod 22, which rotates through the mounting plate 10. An auger blade 24 is fixedly sleeved on the outside of the rotating rod 22. The auger blade 24 matches the mounting cover 23. A discharge port 7 corresponding to the mounting cover 23 is opened on the left side of the mounting plate 10.

[0033] During the rotation of the magnetic roller 18, the magnetic impurities adsorbed on the surface of the magnetic roller 18 are scraped off by the scraper block 26 and fall into the mounting cover 23. The drive assembly drives the rotating rod 22 to rotate, which in turn drives the auger blades 24 to rotate, thus discharging the magnetic impurities in the mounting cover 23 from the impurity discharge port 7.

[0034] The screening assembly includes a partition plate 38, which is fixedly connected to the inner wall of the mounting box 3. The partition plate 38 has a connecting hole. A screen plate 21 is slidably installed between the partition plate 38 and the mounting box 3. The screen plate 21 is inclined. A fixed cover 35 is fixedly connected to both the mounting box 3 and the partition plate 38. A lifting cover 37 is slidably connected to the inner wall of the fixed cover 35. The top of the lifting cover 37 is fixedly connected to the bottom of the screen plate 21. Several sets of second springs 34 are fixedly connected to the top of the inner cavity of the lifting cover 37. The bottom of the second springs 34 is fixedly connected to the bottom of the inner cavity of the fixed cover 35. A vibration mechanism that drives the screen plate 21 to vibrate is installed on the mounting box 3.

[0035] The vibration mechanism includes a cam 31, which is fixedly sleeved on the outside of the rotating rod 22. A lifting frame 32 is fixedly connected to the top of the screen plate 21, and the top of the lifting frame 32 abuts against the bottom of the cam 31.

[0036] Wollastonite powder enters the installation box 3 and falls onto the sieve plate 21. The rotating rod 22 rotates, causing the cam 31 to rotate. With the cooperation of the second spring 34, the lifting frame 32 moves up and down, causing the sieve plate 21 to vibrate. Small particles of wollastonite powder pass directly through the sieve plate 21 and fall onto the left side of the partition plate 38, while large particles of wollastonite powder pass through the connecting hole and fall onto the right side of the partition plate 38.

[0037] The drive assembly includes a motor 11, which is fixedly mounted on the mounting plate 10. A drive gear 12 is fixedly connected to the output end of the motor 11. A gear ring 13 is fixedly sleeved on the outside of the rotating cylinder 2. The drive gear 12 meshes with the gear ring 13. A first rotating mechanism that drives the magnetic roller 18 to rotate is mounted on the mounting plate 10. A second rotating mechanism that drives the rotating rod 22 to rotate is mounted on the mounting box 3.

[0038] When the motor 11 is started, it drives the drive gear 12 to rotate, which in turn drives the gear ring 13 to rotate, which in turn drives the rotating cylinder 2 to rotate. At the same time, the magnetic roller 18 is driven to rotate through the first rotating mechanism, and the rotating rod 22 is driven to rotate through the second rotating mechanism, which in turn drives the impurity removal component and the screening component to operate.

[0039] The first rotating mechanism includes a connecting rod 16, which rotates through the mounting plate 10. The left end of the connecting rod 16 is fixedly connected to the magnetic roller 18. A driven wheel 36 is fixedly sleeved on the outside of the connecting rod 16. A drive wheel 33 is fixedly sleeved on the outside of the output end of the motor 11. A first belt is tensioned between the drive wheel 33 and the driven wheel 36.

[0040] When the motor 11 is running, it drives the drive wheel 33 to rotate, which in turn drives the driven wheel 36 to rotate, which in turn drives the connecting rod 16 to rotate, thereby causing the magnetic roller 18 to rotate.

[0041] The second rotating mechanism includes a transmission wheel 15, which is fixedly connected to the right end of the connecting rod 16. The rotating rod 22 rotates through the mounting box 3. The right end of the rotating rod 22 is fixedly connected to a rotating wheel 14. A second belt is tensioned between the rotating wheel 14 and the transmission wheel 15.

[0042] The rotation of connecting rod 16 drives the transmission wheel 15 to rotate, which in turn drives the rotating rod 22 to rotate via rotating wheel 14.

[0043] An impurity box 6 is provided on the left side of the workbench 1, and a first collection box 4 and a second collection box 5 are slidably installed on the mounting box 3.

[0044] Small particles of wollastonite powder, large particles of wollastonite powder, and magnetic impurities are collected through the first collection box 4, the second collection box 5, and the impurity box 6, respectively.

[0045] A protective cover 30 is fixedly connected to the side of the partition plate 38 near the sieve plate 21. The rotating rod 22 rotates through the protective cover 30, and the lifting frame 32 slides through the protective cover 30. The protective cover 30 serves a protective function, preventing wollastonite powder from accumulating between the cam 31 and the lifting frame 32, thus ensuring the normal operation of the vibration mechanism.

[0046] Working principle: In use, wollastonite powder is poured into the rotating drum 2 through the feed port 8. The motor 11 is started to drive the drive gear 12 to rotate, which in turn drives the gear ring 13 to rotate, thereby driving the rotating drum 2 to rotate and the rotating plate 20 to rotate. The wollastonite powder accumulated at the bottom of the rotating drum 2 is carried by the rotating plate 20 to fall above the first guide plate 17. Under the guidance of the first guide plate 17, the wollastonite powder falls onto the magnetic roller 18. The magnetic impurities are adsorbed on the surface of the magnetic roller 18. The wollastonite powder falls between the mounting cover 23 and the baffle 25 under the action of gravity. The second guide plate 19 guides the wollastonite powder to move a certain distance to the right when it falls. The motor 11 rotates, driving the drive wheel 33 to rotate, which in turn drives the driven wheel 36 to rotate, causing the connecting rod 16 to rotate. This causes the magnetic roller 18 to rotate. During the rotation of the magnetic roller 18, magnetic impurities adsorbed on its surface are scraped off by the scraper block 26 and fall into the mounting cover 23. The rotation of the connecting rod 16 drives the transmission wheel 15 to rotate, which in turn drives the rotating rod 22 to rotate, causing the auger blades 24 to rotate, thus discharging the magnetic impurities in the mounting cover 23 from the discharge port 7. As the rotating cylinder 2 and the magnetic roller 18 continue to rotate, the wollastonite powder moves to the right until it enters the mounting box 3 from the discharge port at the far right and falls onto the screen plate 21. The rotation of the rotating rod 22 drives the cam 31 to rotate, which, with the cooperation of the second spring 34, causes the lifting frame 32 to move up and down, causing the screen plate 21 to vibrate. Small particles of wollastonite powder pass directly through the screen plate 21 and fall onto the left side of the separator plate 38, while large particles of wollastonite powder pass through the connecting hole and fall onto the right side of the separator plate 38. During this process, the wollastonite powder comes into contact with the magnetic roller 18 times, which can effectively remove magnetic impurities from the wollastonite powder and ensure product quality.
