Description

A feeding device for rare earth polishing powder production with filtration function Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to a feeding device for the production of rare earth polishing powder with a filtration function. Background Technology

[0002] Rare earth polishing powder refers to a powder of mixed light rare earth oxides with cerium oxide as the main component, used to improve the surface finish of products or parts. It is typically made from bastnaesite concentrate or soluble rare earth salts through chemical treatment, calcination, crushing, and sieving processes. In the production of rare earth polishing powder, a ball mill is usually used to further process the crushed rare earth materials. Because the particle size of the crushed rare earth materials varies, there are significant volume differences, resulting in different processing times. Directly feeding the materials into the ball mill for uniform processing would affect the overall processing efficiency. Therefore, we propose a feeding device with a filtration function for polishing powder production. Summary of the Invention

Detailed Implementation

[0027] Referring to Figures 1-10, a feeding device for rare earth polishing powder production with filtration function includes a feeding assembly 1, a filter assembly 2 installed inside the feeding assembly 1, and an outer cylinder 11. A first holding part 111 is installed at one end of the outer cylinder 11. The filter assembly 2 includes an inner cylinder 21, a first holding member 22 is installed on the outer surface of the inner cylinder 21, and the first holding part 111 is rotatably connected inside the first holding member 22. Multiple auger-type filter screens 23 are spirally and symmetrically installed on the inner cylinder 21. Each auger-type filter screen 23 consists of a first material filter screen 231, a connecting plate 232, and a first dust filter screen 233. The connecting plate 232 and the first dust filter screen 233 are both arc-shaped. A reprocessing cylinder 24 is fixedly connected to the end of the inner cylinder 21 away from the first clamping member 22. A second dust filter screen 241 is installed on the end of the reprocessing cylinder 24 away from the inner cylinder 21. Multiple protrusions 242 are symmetrically installed on the inner surface of the reprocessing cylinder 24. A second material filter screen 243 is installed at the corner of the reprocessing cylinder 24 near the end of the second dust filter screen 241. The space between the inner surface of the outer cylinder 11 and the outer surface of the inner cylinder 21 forms a feeding channel 12. A drive component 3 for driving the filter component 2 to rotate is installed on the feeding component 1.

[0028] As shown in Figures 5 and 6, the drive assembly 3 includes two parts: a first mounting part 31 and a second mounting part 32. Two first adapter parts 14 are fixedly connected to the outer surface of the outer cylinder 11. A first adapter groove 311 is formed on the inner surface of the first mounting part 31, and a second adapter groove 321 is formed on the inner surface of the second mounting part 32. The two first adapter parts 14 are rotatably connected to the first adapter groove 311 and the second adapter groove 321, respectively. A fixing sleeve 312 is fixedly connected to the first mounting part 31, and a dual-shaft output motor 3 is installed inside the fixing sleeve 312. 13. A second gear 3131 and a third gear 3132 are fixedly connected to the two output ends of the dual-axis output motor 313, respectively. A third gear ring 25 is fixedly connected to one side surface of the first holding member 22. An adapter sleeve 314 is fixedly connected to the side surface of the first mounting part 31 near the third gear ring 25. A limit shaft is rotatably connected inside the adapter sleeve 314. A fourth gear 315 is fixedly connected to one end of the limit shaft, which meshes with both the second gear 3131 and the third gear ring 25. A lifting assembly 4 is installed below the drive assembly 3.

[0029] In the existing production process of rare earth polishing powder, ball mills are usually used to further process the pulverized rare earth materials. Because the pulverized rare earth materials have varying particle sizes and significant volume differences, the required processing time also varies. Directly feeding the materials into the ball mill for uniform processing affects the overall processing efficiency. To solve this problem, this invention includes a feeding assembly 1, a filtering assembly 2, a driving assembly 3, and a lifting assembly 4. During feeding, the lifting assembly 4 first tilts the feeding assembly 1 and the filtering assembly 2, with the inner cylinder 21 higher than the inner cylinder. The reprocessing cylinder 24 is then activated, followed by the dual-shaft output motor 313, which drives the filter assembly 2 to rotate via the drive component 3. Rare earth materials are then fed into the inner cylinder 21. It should be noted that, because the auger filter screen 23 is spirally arranged, its spiral direction varies depending on the rotation direction when the filter assembly 2 rotates. In this invention, when the filter assembly 2 rotates, the spiral direction of the auger filter screen 23 faces the reprocessing cylinder 24. Since the spiral direction of the auger filter screen 23 faces the reprocessing cylinder 24, for materials in… For rare earth materials sliding down the inner wall of the inclined inner cylinder 21 under the influence of gravity, the auger filter screen 23, as the filter assembly 2 rotates, will have extensive contact with the rare earth materials. During this contact, rare earth materials of suitable size will enter the feeding channel 12 through the mesh of the auger filter screen 23 and be fed through the feeding channel 12. Rare earth materials exceeding the mesh size will eventually slide down into the reprocessing cylinder 24, where they will be filtered and screened according to particle size. During this process, the rotating auger filter screen 23 will hinder the downward sliding of the rare earth materials. This prolongs the time required for rare earth materials to slide from the inner cylinder 21 into the reprocessing cylinder 24, increases the contact between the rare earth materials and the screw conveyor filter screen 23, improves the filtration and screening effect, and for rare earth materials with unsuitable particle size, they will eventually gather in the reprocessing cylinder 24. Then, as the reprocessing cylinder 24 rotates, the rare earth materials are carried to a high place and then fall down under the drive of the protruding column 242. During this process, the rare earth materials collide continuously with each other, causing them to break. After breaking, the rare earth materials with suitable particle size enter the feeding channel 12 through the second material filter screen 243.

[0030] After the feeding process is completed, any unqualified rare earth materials need to be discharged. At this time, the lifting component 4 can be used to adjust the filter component 2 so that the reprocessing cylinder 24 is tilted higher than the inner cylinder 21. Then, the dual-shaft output motor 313 is started, and the filter component 2 is driven to rotate through the drive component 3. Under the action of gravity, the rare earth materials in the reprocessing cylinder 24 slide from the reprocessing cylinder 24 toward the inner cylinder 21. During this process, the rotating auger filter screen 23 will promote the discharge of rare earth materials, saving time.

[0031] As shown in Figure 7, the lifting assembly 4 includes two parts: a first electric cylinder 41 and a second electric cylinder 42. Connecting parts 33 are installed on both the first mounting part 31 and the second mounting part 32. A first connecting shaft 411 and a second connecting shaft 421 are respectively installed on the output ends of the first electric cylinder 41 and the second electric cylinder 42. The first connecting shaft 411 and the second connecting shaft 421 are rotatably connected to the connecting parts 33 on the first mounting part 31 and the second mounting part 32, respectively. A first base plate 412 is fixedly connected to the bottom end of the first electric cylinder 41, and a second base plate 422 is fixedly connected to the bottom end of the second electric cylinder 42. A receiving assembly 5 is installed on one end of the filter assembly 2.

[0032] By controlling the lengths of the first electric cylinder 41 and the second electric cylinder 42 respectively, the feeding assembly 1 and the filtering assembly 2 can be adjusted to two different tilt states, corresponding to the filtration and feeding of rare earth materials and the discharge of unqualified rare earth materials respectively. When feeding, the first electric cylinder 41 is long and the second electric cylinder 42 is short. When discharging unqualified rare earth materials, the first electric cylinder 41 is short and the second electric cylinder 42 is long. Switching between the two tilt states is convenient and the operation is simple.

[0033] As shown in Figure 8, the receiving component 5 includes a receiving pipe 51, a receiving part 211 is installed on one end of the inner cylinder 21, a sealing ring 52 that is rotatably connected to the receiving part 211 is fixedly connected to the end of the receiving pipe 51 near the inner cylinder 21, a second adapter part 53 is fixedly connected to the sealing ring 52, a fixing frame 316 is installed on the side surface of the first mounting part 31 near the receiving pipe 51, a limiting groove 317 that is rotatably connected to the second adapter part 53 is installed on the inner surface of the fixing frame 316, and an adjustment component for adjusting the angle of the receiving pipe 51 is installed on the first mounting part 31.

[0034] With the help of the receiving pipe 51, rare earth materials can be fed into the inner cylinder 21 more conveniently, thus facilitating feeding. When discharging unqualified rare earth materials, the receiving pipe 51 can be rotated 180° with the help of the adjusting component to face downwards, thereby facilitating the guidance and collection of unqualified rare earth materials during the discharge process.

[0035] As shown in Figures 9 and 10, the adjustment assembly includes an adjustment motor 318 mounted on the surface of the first mounting part 31 near the receiving pipe 51. A fifth gear 319 is fixedly connected to the output end of the adjustment motor 318. A fourth gear ring 54 that meshes with the fifth gear 319 is mounted on the receiving pipe 51. A touch switch 3181 that is electrically connected to the adjustment motor 318 for controlling the rotation of the adjustment motor 318 is mounted on the surface of the first mounting part 31 near the first electric cylinder 41. A trigger rod 413 for triggering the touch switch 3181 is mounted on the top of the output end of the first electric cylinder 41.

[0036] When switching between the two states of filtering and feeding and discharging unqualified materials in this invention, it is necessary to control and change the length of the first electric cylinder 41 and the second electric cylinder 42, thereby changing the tilt direction of the feeding assembly 1 and the filtering assembly 2. During the process of changing the tilt direction of the feeding assembly 1, the trigger rod 413 will make contact with the touch switch 3181. The trigger rod 413 squeezes and triggers the touch switch 3181, causing the regulating motor 318 to start. The output end of the regulating motor 318 drives the fourth gear ring 54 to rotate through the fifth gear 319, thereby driving the receiving pipe 51 to rotate 180°. According to the needs of the two different states of filtering and feeding and discharging unqualified materials, the orientation of the receiving pipe 51 is automatically adjusted to meet the working requirements.

[0037] As shown in Figures 3 and 4, a dust-prevention assembly is installed between the reprocessing cylinder 24 and the second mounting part 32. The dust-prevention assembly includes a fixing ring 244 mounted on the second dust filter screen 241. One end of the fixing ring 244 is rotatably connected to one side surface of the second mounting part 32. A sealing sleeve is mounted on the second mounting part 32 and rotatably connected to the inner surface of the fixing ring 244. A fixing member 245 is fixedly connected to the inner surface of the fixing ring 244. The fixing member 245 has multiple mounting holes 246, and mounting shafts 247 are rotatably connected to each of the multiple mounting holes 246. The mounting shafts 247 are positioned at the end near the second dust filter screen 241. A fan blade 248 is installed, and a first gear 249 is installed on the end of the mounting shaft 247 away from the second dust filter screen 241. A first gear ring 15 that meshes with the third gear 3132 is installed on the outer cylinder 11. Multiple feeding channels 12 are symmetrically installed on the inner surface of the outer cylinder 11. A baffle 16 is fixedly connected to the inner surface of the feeding channel 12 near the fixed ring 244. A second gear ring 17 that meshes with the first gear 249 is fixedly connected to the inner surface of the baffle 16. The second mounting part 32 is respectively provided with a discharge port facing the feeding channel 12 and a dust discharge pipe 322 facing the second dust filter screen 241.

[0038] After the dual-shaft output motor 313 starts, it drives the first gear ring 15 to rotate via the third gear 3132, thereby driving the outer cylinder 11 to rotate. The outer cylinder 11 rotates in the opposite direction to the inner cylinder 21. The rotation of the outer cylinder 11 drives the spiral feed plate 13 to rotate. The spiral direction of the spiral feed plate 13 is opposite to that of the auger filter screen 23. Therefore, when the outer cylinder 11 drives the spiral feed plate 13 to rotate, the spiral feed plate 13 promotes the downward movement of qualified material in the feeding channel 12, accelerating the downward movement of the qualified material. The qualified material slides through the feeding channel 12 to the discharge port of the second mounting part 32. The discharge port of the second mounting part 32 is connected to the ball mill inlet, completing the feeding process. During this process, because the outer cylinder 11 and the inner cylinder 21 rotate in opposite directions, the second gear ring 15 rotates under the differential speed action. 7 will drive the first gear 249 to rotate rapidly around the mounting shaft 247 through meshing, thereby driving the fan blade 248 to rotate rapidly. This will generate negative pressure on the side of the second dust filter screen 241 near the fixed ring 244, drawing the dust generated in the inner cylinder 21 during the filtration and feeding process into the dust discharge pipe 322, preventing dust from being stirred up and facilitating unified collection and treatment. In the auger filter screen 23, since both the connecting plate 232 and the first dust filter screen 233 are arc-shaped, the air velocity near the connecting plate 232 and the first dust filter screen 233 is faster than the air velocity inside the auger filter screen 23 during the rotation of the auger filter screen 23 with the inner cylinder 21, resulting in lower pressure. This allows the air inside the auger filter screen 23 to be drawn out through the first dust filter screen 233, preventing dust from being stirred up in the feeding channel 12.

[0039] In this invention, when filtration and feeding are required, the first electric cylinder 41 is extended and the second electric cylinder 42 is shortened, adjusting the outer cylinder 11 and inner cylinder 21 so that the first mounting part 31 is higher than the second mounting part 32. Then, the rare earth material is poured into the receiving pipe 51. Under the action of gravity, the material slides down along the receiving pipe 51 and the inner cylinder 21 towards the reprocessing cylinder 24. The dual-shaft output motor 313 is started, and the two output ends of the dual-shaft output motor 313 drive the second gear 3131 and the third gear 3132 to rotate synchronously. The second gear 3131 drives the third gear ring 25 to rotate through the fourth gear 315 and the limiting shaft. The third gear ring 25 then drives the inner cylinder 21 to rotate, and the auger filter screen 23 moves along with the inner cylinder 21. The rotating part makes extensive contact with the rare earth material. During the contact process, rare earth material of suitable size enters the feeding channel 12 through the mesh of the auger filter screen 23. Rare earth material exceeding the mesh size eventually slides down into the reprocessing cylinder 24. Rare earth material of unsuitable particle size slides down and gathers in the reprocessing cylinder 24. Then, as the reprocessing cylinder 24 rotates, the rare earth material is carried to a high place and then falls down under the drive of the protrusion 242. During this process, the rare earth material collides continuously with each other, causing it to break. After breaking, rare earth material of suitable particle size enters the feeding channel 12 through the second material filter screen 243 and finally enters the ball mill through the discharge port on the second mounting part 32 to complete the filtration feeding.

[0040] After the dual-shaft output motor 313 starts, it drives the first gear ring 15 to rotate via the third gear 3132, thereby driving the outer cylinder 11 to rotate. The rotation of the outer cylinder 11 drives the spiral feed plate 13 to rotate. The spiral direction of the spiral feed plate 13 is opposite to that of the auger filter screen 23. Therefore, when the outer cylinder 11 drives the spiral feed plate 13 to rotate, the spiral feed plate 13 promotes the downward movement of qualified material in the feeding channel 12, accelerating the downward movement of the qualified material. The qualified material slides through the feeding channel 12 into the second mounting part 32. At the discharge port, the discharge port of the second mounting part 32 is connected to the feed port of the ball mill to complete the feeding. During this process, since the outer cylinder 11 and the inner cylinder 21 rotate in opposite directions, under the differential speed action of the two, the second gear ring 17 will drive the first gear 249 to rotate rapidly around the mounting shaft 247 through meshing, thereby driving the fan blade 248 to rotate rapidly. A negative pressure is generated on the side of the second dust filter screen 241 near the fixed ring 244, which draws the dust generated in the inner cylinder 21 during the filtration feeding process into the dust discharge pipe 322 to avoid dust emission and facilitate unified collection and treatment.

[0041] When it is necessary to discharge unqualified rare earth materials, the first electric cylinder 41 is shortened and the second electric cylinder 42 is extended, adjusting the outer cylinder 11 and the inner cylinder 21 so that the first mounting part 31 is lower than the second mounting part 32. During the process of changing the tilt direction of the feeding assembly 1, the trigger rod 413 will make contact with the touch switch 3181. The trigger rod 413 squeezes and triggers the touch switch 3181, causing the regulating motor 318 to start. The output end of the regulating motor 318 drives the fourth gear ring 54 to rotate through the fifth gear 319, thereby driving the receiving pipe 51 to rotate 180° and adjust it to a downward position. Then, the dual-shaft output motor 313 is started, driving the auger filter screen 23 to rotate. Under the action of gravity, the rare earth materials in the reprocessing cylinder 24 slide from the reprocessing cylinder 24 towards the inner cylinder 21 and are finally discharged through the receiving pipe 51. During this process, the rotating auger filter screen 23 will promote the discharge of rare earth materials and save time.
