Description

Technical Field

[0001] This invention relates to the field of diamond micro powder shaping and pulverizing, and in particular to an energy-saving integrated equipment for diamond micro powder shaping and pulverizing. Background Technology

[0002] Diamond micron powder is an ultra-fine abrasive material with extremely high hardness, high wear resistance, and high thermal conductivity. It is widely used in precision machining fields such as precision optical polishing, semiconductor wafer processing, cemented carbide grinding, and high-end mold polishing. In the industrial production process of diamond micron powder, crushing, grading, and shaping are the core key processes that determine the uniformity of micron powder particle size, particle roundness, and product quality, directly affecting the accuracy of subsequent polishing and the surface quality of the workpiece. Currently, most mainstream processing equipment in the industry adopts a separate structure for crushing and shaping equipment, independently completing the crushing and shaping operations, and is equipped with independent air supply, material conveying, and grading mechanisms. This equipment has low integration, high energy consumption, and limited processing accuracy, making it difficult to meet the production needs of high-end ultra-fine diamond micron powder.

[0003] In existing technologies, the crushing and shaping processes of diamond micron powder are typically set up independently. The crushing and shaping cylinders each have their own dedicated air supply sources, and these two air supply systems operate independently. This results in high overall power consumption, low energy efficiency, and high operating costs, failing to meet the development needs of energy-saving industrial production. Regarding micron powder grading, existing integrated crushing and shaping equipment relies solely on a grading impeller to classify the micron powder into coarse and fine particles. The grading structure is simple and lacks secondary filtration and protection. A small amount of large particles and agglomerated particles mixed in with the crushed micron powder easily pass through the grading impeller and enter the shaping cylinder along with the qualified fine powder. Once inside the shaping cylinder, these large particles collide violently with the inner wall of the cylinder and the high-speed moving micron powder particles, causing damage to the internal precision structure of the shaping cylinder, accelerating equipment wear, shortening equipment lifespan, and resulting in shaped micron powder with sharp edges and uneven particle size. This significantly reduces the accuracy of micron powder grading and product quality, making it difficult to guarantee product qualification rates.

[0004] In addition, existing diamond micron powder pulverizing equipment often uses a fixed airflow design for the duct, making it impossible to adjust the airflow angle and direction. This results in uneven airflow distribution within the pulverizing cylinder, creating dead zones. During high-speed pulverization, some fine particles easily accumulate in these dead zones, preventing them from participating in the pulverization and grading process. This not only reduces pulverization efficiency and raw material utilization but also leads to agglomeration and clumping of the accumulated particles, increasing the difficulty of cleaning. Frequent shutdowns for cleaning severely impact continuous production efficiency, hindering the large-scale, high-quality, and energy-efficient production of diamond micron powder. Therefore, this paper proposes an energy-saving integrated diamond micron powder shaping and pulverizing equipment. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes an energy-saving integrated diamond micro powder shaping and pulverizing equipment, which solves the problems of high energy consumption due to independent air source in existing pulverizing and shaping equipment, lack of secondary filtration in grading which easily leads to the mixing of large particles that damage the shaping cylinder, and fixed air supply to the pulverizing cylinder which easily creates dead corners and causes powder retention.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0007] An energy-saving integrated diamond micro powder shaping and pulverizing equipment includes a blower, a pulverizing cylinder, and a shaping cylinder coaxially mounted from bottom to top. A base frame is installed on one side of the blower, and a feed hopper is installed on the base frame. A feeding pipe is installed between the feed hopper and the pulverizing cylinder.

A disc communicating with the opening is mounted on the lower end of each flexible air sleeve. A square tube is connected to the outer side of both the shaping chamber and the guiding chamber. Two square tubes are connected to a square air chamber.

[0008] The square air chamber is fitted with a filter collar that mates with the square tube. The filter collar extends to the outside of the square air chamber and is fitted with a ratchet. A sliding frame is slidably mounted on the square air chamber, and a drive assembly is mounted on the sliding frame. The drive assembly drives the ratchet to rotate the filter collar. An adjustment assembly is mounted on the base frame. The adjustment assembly drives the disc to deflect when the sliding frame slides downward. A return assembly is mounted between the square tube in the guide chamber and the feeding pipe. The return assembly is used to send the substandard micro powder filtered inside the sliding frame to the feeding pipe when the sliding frame slides downward.

[0009] Preferably, a square air duct that penetrates the inner wall of the air duct is tangentially connected to the outer side of the air duct. An axially arranged electric spiral blade is installed inside the feeding pipe. An electric crushing disc is installed inside the crushing cylinder. A guide ring is provided at the top of the crushing cylinder between the electric crushing disc and the classifying impeller. The guide ring is connected to the top of the crushing cylinder through multiple circumferentially arranged connecting blocks. A sleeve is fitted on the upper end of the classifying impeller.

The filter collar rotates and fits into contact with the openings of the two square tubes inside the square air chamber.

[0012] Preferably, the drive assembly includes a telescopic component, a limiting slide box, and a ratchet. Two telescopic components are arranged and installed on the top of the square air chambers, and the upper output ends of the two square air chambers are connected to the upper end of the slide frame. The limiting slide box is installed on the inner wall of one side of the slide frame. One end of the ratchet is slidably sleeved in the limiting slide box and is connected to the inner wall of the limiting slide box by multiple springs at equal intervals. The other end extends to the outside of the limiting slide box and engages with the ratchet.

[0013] Preferably, each end of the square air chamber is connected to a frame, and each frame is connected to a guide rod between its upper and lower inner walls. Each side of the sliding frame is connected to a sleeve, and the sleeve is slidably fitted inside the guide rod.

[0014] Preferably, the adjusting assembly includes a sleeve, a second guide rod, a first sleeve plate, and a push rod. The sleeve is fitted onto the lower end of the disc and rotatably fitted against the lower inner wall of the air duct. The second guide rod is connected to both sides of the base frame. The first sleeve plate is slidably fitted onto the outer sides of the second guide rods on both sides. A second spring fitted onto the outer side of the second guide rod is connected between the first sleeve plate and the base frame. The push rod slides through the air duct in a sealed manner. A second rotating plate is rotatably connected between the push rod and the first sleeve plate at the outer end of the air duct, and a first rotating plate is rotatably connected between the push rod and the sleeve at the inner end of the air duct. Top rods are connected to both sides of the lower end of the sliding frame, and the lower ends of the top rods are in contact with the first sleeve plate.

[0015] Preferably, the return material assembly includes a return hopper, a through-hole, a baffle seat, a guide rod three, a sleeve plate two, and a deflector plate. The return hopper is connected to the lower end of the square tube outside the guide chamber and communicates with the square tube and the feeding pipe. The through-hole is opened through both sides of the return hopper. The baffle seat is slidably sleeved in the through-hole and extends to the inner and outer sides of the return hopper respectively. The baffle seats on both sides abut against each other at the inner end of the return hopper. The guide rod three is connected to both sides of the return hopper. The baffle seat is slidably sleeved on the outer side of the guide rod three on its respective side at the outer end of the return hopper. A tension spring sleeved on the outer side of the guide rod three is connected between the baffle seat and the end of the guide rod three away from the return hopper. Two sleeve plates two are provided and slidably arranged on both sides below the return hopper. Each sleeve plate two is rotatably connected to the baffle seat on its respective side by a rotating plate three. The deflector plate is connected to the lower end of the sliding frame, and the upper end of the deflector plate abuts against the upper end of the sleeve plate two.

[0016] Preferably, the baffle seats on both sides are connected to the lower side of their adjacent ends in the return hopper, and the protrusions abut against the through opening. The lower end of the square air chamber is connected to a slide, and the second sleeve is slidably sleeved on the outside of the slide.

[0017] Preferably, the feeding pipe has a square opening, which is fitted into the lower end of the return hopper.

[0018] The beneficial effects of this invention are:

[0019] 1. The technical solution of this invention controls the telescopic component to extend and retract, causing the sliding frame to move up and down. This, in turn, causes the ratchet sliding inside the upper limit sliding box to engage with the ratchet during its downward movement, rotating the ratchet and, through the rotating shaft, causing the filter collar to rotate. Since the filter collar is fitted onto the openings of the upper and lower square tubes respectively, when the area of ​​the filter collar fitted onto the opening of the lower square tube rotates to fit onto the opening of the upper square tube, the area of ​​the filter collar previously fitted onto the opening of the upper square tube also alternately rotates to fit onto the opening of the lower square tube. This allows for the exchange of the inlet and outlet surfaces of the corresponding areas of the filter collar. This design allows the filter ring on the lower side near the guide chamber to be purged of particles that were originally clogged by coarse particles in the guide chamber when it rotates to the upper side near the shaping chamber. This improves the smoothness of the filter ring and prevents clogging. It also filters out some diamond powder that did not meet the standards after being classified by the classifying impeller and places it in the square tube of the guide chamber, improving the accuracy of the sorting and conveying of diamond powder after crushing. It also allows some of the airflow in the crushing cylinder to enter the shaping chamber, reducing the airflow conveying power in the shaping cylinder, improving energy efficiency and reducing energy consumption.

[0020] 2. The technical solution of the present invention can also drive the top rod to move down during the downward movement of the sliding frame, and push the sleeve plate to move down, thereby driving the second rotating plate to rotate, pushing the push rod to extend into the air duct, and driving the first rotating plate to push the sleeve and the disc to deflect, so that the flexible air sleeve deforms and tilts, thereby changing the direction of the airflow from the flexible air sleeve to the crushing cylinder through the opening, so that the air direction can be blown into the crushing cylinder as thoroughly as possible, realizing the conveying of the crushed fine powder in the crushing cylinder, while also preventing the fine powder or diamond powder coarse material from falling into the dead corner of the crushing cylinder, improving the stability and efficiency of the crushing cylinder itself;

[0021] 3. The technical solution of this invention, during the downward movement of the sliding frame, also drives the deflector plate downward. Then, after the deflector plate is no longer resisting, the tension of the tension spring pulls the two side baffles on the guide rods three on both sides of the return hopper, causing them to slide away from each other. The rotating plate three pushes the two side baffles to slide downward on the slide frame, allowing the coarse material collected in the return hopper that was filtered out by the filter ring to fall back into the feeding pipe through the open baffles on both sides. It is then re-transported into the crushing cylinder by the electric spiral blades for crushing, achieving multiple rounds of thorough crushing and improving the overall automation and efficiency of the crushing process.

Detailed Implementation

[0033] The following will be combined with the appendix Figure 1 To be continued Figure 9The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: As Figures 1-9 As shown, this invention discloses an energy-saving integrated diamond micro powder shaping and crushing equipment, including a blower 1, a crushing cylinder 2, and a shaping cylinder 3 coaxially mounted from bottom to top. A base frame 34 is installed on one side of the blower 1, and a feed hopper 5 is installed on the base frame 34. A feeding pipe 6 is installed between the feed hopper 5 and the crushing cylinder 2. The shaping cylinder 3 is divided into an upper shaping chamber 11 and a lower guiding chamber 12. A classifying impeller 9 is mounted in a rotating manner between the crushing cylinder 2 and the guiding chamber 12. Multiple circumferentially arranged openings 17 are opened through the blower 1 and the crushing cylinder 2. A flexible air sleeve 18 is connected to the lower end of the opening 17. A disc 19 that communicates with the opening 17 is mounted on the lower end of each flexible air sleeve 18. A square tube 21 is connected to the outside of both the shaping chamber 11 and the guiding chamber 12. Two square tubes 21 are connected to a square air chamber 22.

[0035] A filter collar 24 is rotatably fitted inside the square air chamber 22 to mate with the square tube 21. The filter collar 24 extends to the outside of the square air chamber 22 and is fitted with a ratchet 25. A sliding frame 28 is slidably mounted on the square air chamber 22. A drive assembly is mounted on the sliding frame 28 to drive the ratchet 25 to rotate the filter collar 24. An adjustment assembly is mounted on the base frame 34 to drive the disc 19 to deflect when the sliding frame 28 slides downward. A return assembly is mounted between the square tube 21 on the guide chamber 12 and the feeding pipe 6. The return assembly is used to send the substandard micro powder filtered inside the sliding frame 28 into the feeding pipe 6 when the sliding frame 28 slides downward.

[0036] A square air duct 4, which runs through the inner wall of the air duct 1, is tangentially connected to the outer side of the air duct 1. An electric spiral blade 7, arranged axially, is installed inside the feeding pipe 6. An electric crushing disc 8 is installed inside the crushing cylinder 2. A guide ring 10 is set at the top of the crushing cylinder 2 between the electric crushing disc 8 and the classifying impeller 9. The guide ring 10 is connected to the top of the crushing cylinder 2 through multiple connecting blocks arranged in a circumferential array. A sleeve 13 is fitted on the upper end of the classifying impeller 9. The sleeve 13 is sealed and rotated with the guide chamber 12, so that the guide ring 10 can guide the crushed diamond powder mixture from the side wall of the crushing cylinder 2 to the outside of the classifying impeller 9 by guiding the airflow. The classifying impeller 9 then classifies the diamond powder. The unsuitable diamond powder will be thrown back to the inner outer edge of the crushing cylinder 2 through the gap between the bottom of the guide ring 10 and the electric crushing disc 8 for further crushing.

[0037] An air supply ring 15 is installed at the bottom of the shaping chamber 11. A round pipe 14 is connected to the air supply ring 15, which extends through the shaping chamber 11 to the outside of the shaping cylinder 3. An exhaust pipe 16 is connected to the upper end of the shaping chamber 11, which extends through the shaping chamber 11 to the outside of the shaping cylinder 3. A collection chamber 52 is also installed at the bottom of the shaping chamber 11. The collection chamber 52 can collect some impurities in the shaping chamber 11 of the shaping cylinder 3, so as to avoid impurities from staying in the shaping chamber 11 for a long time and affecting the shaping efficiency and quality.

[0038] The inner wall of the air supply ring 15 is equipped with multiple airflow nozzles arranged in a tangential circumferential array to deliver high-speed airflow into the shaping chamber 11.

[0039] A rotating shaft 23 is fitted through a sealed sleeve inside a square air chamber 22. A filter collar 24 and a ratchet 25 are respectively fitted on the inner and outer ends of the rotating shaft 23 in the square air chamber 22. The filter collar 24 rotates and fits into the openings of the two square tubes 21 inside the square air chamber 22, ensuring the stability of the ratchet 25 and the filter collar 24 rotating synchronously.

[0040] By adding coarse diamond powder into the feed hopper 5 and activating the electric spiral blades 7, the coarse diamond powder is conveyed to the crushing cylinder 2 through the feed pipe 6. The powder is then finely crushed by the electric crushing disc 8 in the crushing cylinder 2. Simultaneously, air is supplied to the air duct 1 through the square air duct 4. The airflow enters the crushing cylinder 2 through the flexible air sleeve 18 and the opening 17, and is guided by the flow guide ring 10 to blow the crushed diamond powder around the classifying impeller 9. By controlling the rotation of the classifying impeller 9, the diamond powder is sent into the guide chamber 12. The powder then passes through the square pipe 21 outside the guide chamber 12, the filter ring 24, the square air chamber 22, and the square pipe 21 outside the shaping chamber 11, until it enters the shaping chamber 11 for impact shaping. Finally, the qualified powder is discharged through the exhaust pipe 16 and enters the subsequent cyclone collector and bag filter for further processing.

[0041] Example 2: Figures 1-9 As shown, this invention discloses an energy-saving integrated diamond micro powder shaping and pulverizing equipment. Compared with Embodiment 1, this embodiment discloses the structure of the drive component.

[0042] The drive assembly includes a telescopic component 30, a limiting slide box 31, and a ratchet 32. Two telescopic components 30 are arranged and installed on the top of the square air chamber 22. The upper output ends of the two square air chambers 22 are connected to the upper end of the slide frame 28. The limiting slide box 31 is installed on the inner wall of one side of the slide frame 28. One end of the ratchet 32 ​​is slidably sleeved in the limiting slide box 31 and is connected to the inner wall of the limiting slide box 31 by multiple springs 33 at equal intervals. The other end extends to the outside of the limiting slide box 31 and engages with the ratchet 25.

[0043] The square air chamber 22 has a frame 26 connected to both ends of its side. Each frame 26 has a guide rod 27 connected between its upper and lower inner walls. The sliding frame 28 has a sleeve 29 connected to both sides of its side, and the sleeve 29 is slidably fitted inside the guide rod 27.

[0044] By controlling the telescopic component 30 to extend and retract, the sliding frame 28 moves up and down, thereby causing the ratchet 32 ​​sliding inside its upper limit sliding box 31 to engage with the ratchet 25 during its downward movement, causing the ratchet 25 to rotate. This, in turn, drives the filter collar 24 to rotate via the rotating shaft 23. When the ratchet 32 ​​is driven upward, it will abut against the ratchet 25 and be compressed back into the limit sliding box 31, achieving unidirectional rotation of the ratchet 25. Since the filter collar 24 is fitted onto the openings of the upper and lower square tubes 21 respectively, when the area of ​​the filter collar 24 fitted onto the opening of the lower square tube 21 rotates to fit onto the opening of the upper square tube 21, the area of ​​the filter collar 24 previously fitted onto the opening of the upper square tube 21 also alternately rotates to fit onto the opening of the lower square tube 21. The combined design allows for the exchange of air intake and exhaust surfaces in the corresponding area of ​​the filter ring 24. This ensures that when the filter ring 24 on the lower side near the guide chamber 12 rotates to the upper side near the shaping chamber 11, particles that were originally clogged by coarse particles in the guide chamber 12 can be blown away, improving the smoothness of the filter ring 24 and preventing blockage. At the same time, it can also filter out some substandard diamond powder that has been classified by the classifying impeller 9 and filter it into the square tube 21 of the guide chamber 12, improving the accuracy of sorting and conveying the micro powder after diamond crushing. It also allows some of the airflow in the crushing cylinder 2 to enter the shaping chamber 11, reducing the airflow conveying power in the shaping cylinder 3, improving energy efficiency and reducing energy consumption.

[0045] Example 3: Figures 1-9 As shown, this invention discloses an energy-saving integrated equipment for shaping and pulverizing diamond micro powder. Compared with Embodiment 2, this embodiment discloses the structure of the adjustment component.

[0046] The adjustment assembly includes a sleeve 20, a second guide rod 35, a first sleeve plate 36, and a push rod 38. The sleeve 20 is fitted onto the lower end of the disc 19 and rotates with the lower inner wall of the air duct 1. The second guide rod 35 is connected to both sides of the base frame 34. The first sleeve plate 36 is slidably fitted onto the outer side of the second guide rod 35 on both sides. A second spring 37 fitted onto the outer side of the second guide rod 35 is connected between the first sleeve plate 36 and the base frame 34. The push rod 38 slides through the air duct 1 in a sealed manner. A second rotating plate 40 is rotatably connected between the push rod 38 and the first sleeve plate 36 on the outer side of the air duct 1, and a first rotating plate 39 is rotatably connected between the push rod 38 and the sleeve 20 at one end inside the air duct 1. Top rods 41 are connected to both sides of the lower end of the sliding frame 28, and the lower end of the top rods 41 is in contact with the first sleeve plate 36.

[0047] As the sliding frame 28 moves downward, it can also drive the top rod 41 downward and push the sleeve plate 36 downward, thereby driving the rotating plate 40 to rotate, pushing the push rod 38 to extend into the air duct 1, and driving the rotating plate 39 to push the sleeve 20 and the disc 19 to deflect, causing the flexible air sleeve 18 to deform and tilt, thereby changing the direction of the airflow from the flexible air sleeve 18 to the crushing cylinder 2 through the opening 17, so that the airflow can be blown into the crushing cylinder 2 as thoroughly as possible. This achieves the conveying of the crushed fine powder in the crushing cylinder 2, while also preventing the fine powder or diamond powder coarse material from falling into the dead corner of the crushing cylinder 2, thus improving the stability and efficiency of the crushing cylinder 2's operation.

[0048] Example 4: Figures 1-9 As shown, this invention discloses an energy-saving integrated equipment for shaping and pulverizing diamond micro powder. Compared with Embodiment 3, this embodiment discloses the structure of the material return component.

[0049] The return assembly includes a return hopper 42, an inlet 44, a baffle seat 45, a guide rod 46, a sleeve plate 49, and a deflector plate 51. The return hopper 42 is connected to the lower end of the square tube 21 outside the guide chamber 12 and communicates with the square tube 21 and the feeding pipe 6. The inlet 44 is opened through both sides of the return hopper 42. The baffle seat 45 is slidably fitted inside the inlet 44 and extends to the inner and outer sides of the return hopper 42 respectively. The baffle seats 45 on both sides abut against each other at the inner end of the return hopper 42. The guide rod 46 is connected to both sides of the return hopper 42. The seat 45 is slidably sleeved on the outside of the guide rod 46 on one side of the outer end of the return hopper 42. A tension spring 47 sleeved on the outside of the guide rod 46 is connected between the baffle seat 45 and the end of the guide rod 46 away from the return hopper 42. There are two sleeve plates 49, which are slidably set on both sides below the return hopper 42. Each sleeve plate 49 is rotatably connected to the baffle seat 45 on one side by a rotating plate 50. The lever 51 is connected to the lower end of the slide frame 28, and the upper end of the lever 51 is in contact with the upper end of the sleeve plate 49.

[0050] Both sides of the baffle seat 45 are connected to the lower side of the close end of the return hopper 42 with protrusions. The protrusions abut against the through hole 44. The lower end of the square air chamber 22 is connected to the slide 48. The second sleeve 49 is slidably sleeved on the outside of the slide 48. The feeding pipe 6 has a square opening 43, which is fitted with the lower end of the return hopper 42.

[0051] As the sliding frame 28 moves downward, it can also drive the deflector plate 51 downward. Then, after the deflector plate 51 is no longer resisting, the sleeve plate 49, through the tension of the tension spring 47, pulls the two side baffle seats 45 to slide away from each other on the guide rods 46 on both sides of the return hopper 42. The rotating plate 50 pushes the sleeve plate 49 to slide downward on the slide frame 48, so that the coarse material collected in the return hopper 42 that does not meet the filter requirements due to the filter ring 24 falls back into the feeding pipe 6 through the baffle seats 45 that are opened on both sides, and is then transported back to the crushing cylinder 2 for crushing by the electric spiral blades 7. This achieves multiple repeated crushing and improves the overall automation and efficiency of crushing.

[0052] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
