Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and in particular to the application of a diamond micro powder suspension mixing device in bearing manufacturing. Background Technology

[0002] Diamond micron powder refers to diamond particles with a particle size of 36-54 micrometers, and includes monocrystalline diamond micron powder and polycrystalline diamond micron powder. Due to the large production volume and wide range of applications of monocrystalline diamond micron powder, the industry generally refers specifically to monocrystalline diamond micron powder. Monocrystalline diamond micron powder is produced by hydrostatic pressing of synthetic diamond monocrystalline abrasive grains, which are then crushed, shaped, and processed using special processes for superhard materials.

[0003] A diamond micro powder suspension stirring device for bearing steel balls, application number CN202022654880.8, uses a stirring fan structure and auxiliary plate at the bottom to uniformly stir the micro powder inside the stirring chamber, preventing the micro powder from settling at the bottom of the stirring chamber. A rotating motor drives a connecting rod with a bend to rotate. When rotating, the connecting rod drives the vibrating head at the front end to rotate, so that the vibrating head repeatedly hammers the surface of the feeding cylinder, thereby creating a certain degree of vibration, which is conducive to the feeding of micro powder and avoids residue in the feeding cylinder.

[0004] However, fine powder particles are small in size, have a large specific surface area and high surface energy, and lack nearby coordinating atoms, resulting in a large number of unsaturated bonds on the particle surface. They have high surface activity and are in a thermodynamically unstable state, making them prone to spontaneous agglomeration. Existing stirring devices are not very effective at stirring micro-powder clumps floating on the liquid surface, making it impossible for diamond micro-powder to be stably dispersed in the liquid. This results in poor flocculation of the suspension formed after stirring, thus reducing the quality of the finished diamond micro-powder suspension.

[0005] Therefore, the above problems are solved by using a diamond micron powder suspension stirring device. Summary of the Invention

[0006] This invention discloses a diamond micro powder suspension stirring device, which aims to solve the technical problem in the background art that existing diamond micro powder suspension stirring devices cannot effectively handle the problem that diamond micro powder is prone to agglomeration and floating on the liquid surface during stirring.

[0016] By incorporating a downward-pressing stirring module, the diamond micro powder can be stirred conveniently and quickly using a pressure plate and stirring rod. This ensures the stirring effect while greatly shortening the stirring time, thereby improving the efficiency of preparing diamond micro powder suspensions.

[0017] Preferably, the bottom of the lower pressure plate is provided with a slide between two sets of water leakage grooves. A first wedge-shaped grinding seat is slidably assembled in each set of slides. An airbag is assembled between one side wall of the first wedge-shaped grinding seat and the inner wall of the slide.

[0022] The application of the diamond micron powder suspension stirring device described above in bearing manufacturing can improve processing quality, extend bearing life, reduce production costs, and enhance the automation and environmental protection level of the entire production process.

[0023] Beneficial effects:

[0024] 1. This invention utilizes a tapping feeding module to scrape and tap the micro-powder on the inner wall of the feeding hopper, preventing the diamond micro-powder from failing to dissolve in time due to excessive feeding. A downward-pressing stirring module then presses the clumps of diamond micro-powder into the liquid and stirs them, breaking up the clumps and mixing them into the liquid. This downward-pressing stirring module effectively stirs and breaks up the clumps of diamond micro-powder floating on the liquid surface, ensuring stable dispersion of the diamond micro-powder in the liquid. This guarantees the flocculation effect of the stirred diamond micro-powder suspension and improves the quality of the finished suspension.

[0025] 2. In the mixing operation of the downward stirring module of the present invention, the second wedge plate can generate a pushing force on the particles and clumps floating on the liquid surface, thereby pushing the particles and clumps onto the wedge surface of the first wedge plate. Then, the second wedge plate squeezes the first wedge plate. In this way, while the stirring component is used for mixing, the wedge extrusion between the second and first wedge plates can be used to grind and break up the particles and clumps. Gas can be introduced into the liquid to generate airflow, causing the powder clumps and particles that have not been incorporated into the liquid to float on the liquid surface with the airflow. This facilitates grinding and crushing by the extrusion of the first and second wedge grinding seats, and can provide effective anti-clumping measures during suspension preparation.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The diamond micro powder suspension stirring device disclosed in this embodiment is mainly used in scenarios where existing diamond micro powder suspension stirring devices cannot effectively handle the situation where diamond micro powder tends to clump together and float on the liquid surface during stirring.

[0037] like Figure 1-8 As shown, this embodiment provides a diamond micron powder suspension stirring device, including a tank 1. Two symmetrical supports 2 are fixedly connected to the outside of the tank 1. A top cover 3 is fixedly connected to the upper side of the tank 1, and a round hole is opened on the top cover 3. A feeding hopper 4 is fixedly connected inside the round hole. A round opening is opened at the bottom of the tank 1, and a discharge pipe 7 is fixedly connected inside the round opening. An electronic valve 8 is installed on the discharge pipe 7. A downward stirring module 5 is installed on the tank 1, and a knocking feeding module 6 is installed on the top cover 3.

[0038] During the process of conveying diamond micro powder into tank 1 through hopper 4, the tapping feeding module 6 scrapes and taps the micro powder on the inner wall of hopper 4, allowing the diamond micro powder to smoothly enter tank 1. The diamond micro powder falls onto the liquid in tank 1. Due to the liquid adhering to the surface of the micro powder, it quickly clumps together, forming a shell. This prevents the micro powder inside the shell from dissolving into the liquid. The tension between the air inside the shell and the micro powder and the liquid surface causes the clumps of micro powder to float on the liquid surface. The downward stirring module 5 presses the clumps of diamond micro powder down into the liquid and stirs them, thereby breaking up the clumps and mixing them into the liquid. The electronic valve 8 is activated, allowing the discharge pipe 7 to discharge the suspension in tank 1. The device uses the downward stirring module 5 to effectively stir and break up the clumps of diamond micro powder floating on the liquid surface, thereby allowing the diamond micro powder to be stably dispersed in the liquid, ensuring the flocculation effect of the diamond micro powder suspension after stirring, and improving the quality of the finished suspension.

[0039] Please see Figures 2-8 The downward stirring module 5 includes a downward pressing plate 508, which is located inside the tank 1. A downward pressing rod 501 is provided on the upper side of the downward pressing plate 508, and four symmetrically distributed stirring rods 520 are provided below the downward pressing plate 508. A fixing frame 502 is fixedly connected to the upper side of the top cover 3. A motor 503 is installed inside the fixing frame 502. The output end of the motor 503 is connected to a rotating rod 504 via a coupling. The outside of the rotating rod 504 contacts the upper side of the downward pressing rod 501, and a connecting plate 505 is fixedly connected to the outside of the downward pressing rod 501. The upper part of the connecting plate 505... A spring 506 is fixedly connected to the side, and the spring 506 surrounds the outside of the lower pressure rod 501. The end of the spring 506 away from the connecting plate 505 is fixedly connected to the bottom of the top cover 3. A contact frame 507 is fixedly connected to the bottom of the lower pressure rod 501. The bottom of the contact frame 507 is fixedly connected to the upper side of the lower pressure plate 508. A circular groove is opened on the lower pressure plate 508. A main shaft 510 is movably connected in the circular groove. A second motor 511 is installed in the contact frame 507. The output end of the second motor 511 is connected to the upper side of the main shaft 510 through a coupling. A stirring assembly is fixedly mounted on the main shaft 510.

[0040] Start motor 503. Motor 503 drives rotating rod 504 to rotate one revolution, causing rotating rod 504 to press down on pressing rod 501. The pressing down rod 501 drives pressing plate 508 to cover the floating and agglomerated diamond powder, pressing the powder into the liquid. Start motor 511. Motor 511 drives main shaft 510 to rotate, which in turn drives stirring assembly to rotate.

[0041] The stirring assembly includes an isolation cover 509 fixed to the outside of the main shaft 510. The isolation cover 509 is located inside the contact frame 507, and its bottom is fixedly connected to the upper side of the lower pressure plate 508. Two symmetrical main crossbars 515 are fixedly connected to the outside of the main shaft 510. Each of the two main crossbars 515 has two symmetrical openings. A secondary shaft 516 is movably connected to each of the two openings on the same side. Gears 517 are fixedly connected to the outside of each secondary shaft 516. An internal gear ring 518 is fixedly connected to the bottom of the pressure plate 508. The internal gear ring 518 meshes with two gears 517. Two circumferentially distributed winch shovels 521 are fixedly connected to the outside of the main shaft 510. The winch shovels 521 are located below the main crossbar 515. Two symmetrical secondary crossbars 519 are fixedly connected to the outside of the two secondary shafts 516. Two symmetrical small holes are opened on each of the secondary crossbars 519. The same stirring rod 520 is fixedly connected to the two small holes on the same side.

[0042] When the main shaft 510 rotates, it can drive the winch shovel 521 to pick up the fine powder that has sunk to the bottom of the tank 1. During the rotation of the main shaft 510 and the main crossbar 515, the gear 517 meshes with the internal gear ring 518 and rotates, causing the secondary shaft 516 connected to the gear 517 to drive the stirring rod 520 to rotate around the secondary shaft 516 as the axis, thereby continuously breaking up and stirring the clumps of fine powder. After the rotating rod 504 and the lower pressure rod 501 are no longer in contact, the spring 506 drives the lower pressure rod 501 to rise, thereby causing the lower pressure plate 508 to rise from the liquid.

[0043] It should be noted that four circumferentially distributed water leakage grooves 512 are provided on the lower pressure plate 508. Each water leakage groove 512 has a notch on the inner wall of the side closest to the motor 511. A thin rod is fixedly connected to each notch, and a torsion spring 514 is fixedly connected to the outside of each thin rod. A water baffle plate 513 is fixedly connected to the end of each torsion spring 514 away from the thin rod. The outside of each water baffle plate 513 is in contact with the inner wall of the water leakage groove 512 on the same side. Therefore, when the lower pressure plate 508 rises, the liquid above the lower pressure plate 508 overcomes the torsion of the torsion spring 514 and pushes the water baffle plate 513 out of the water leakage groove 512, so that the liquid can flow from the outside of the water leakage groove 512 and the lower pressure plate 508 to the bottom of the lower pressure plate 508.

[0044] The downward stirring module 5 is mainly used in the downward stirring stage of the downward stirring process. Specifically, the downward stirring module 5 utilizes the downward pressure plate 508 and the stirring rod 520 to conveniently and quickly complete the stirring operation of diamond micron powder. Simultaneously, when the main crossbar 515 rotates, it drives the second wedge plate 532 to rotate synchronously. During each rotation, the second wedge plate 532 can generate a pushing force on particles and agglomerates floating on the liquid surface, thereby pushing the particles and agglomerates towards the wedge-shaped surface of the first wedge plate 531. Then, the second wedge plate 532 squeezes the first wedge plate 531, thus utilizing the stirring components... While stirring and mixing, the particles and agglomerates can be ground and broken by the wedge-shaped extrusion between the second wedge plate 532 and the first wedge plate 531. After the second wedge plate 532 extrudes the first wedge plate 531, the second wedge plate 532 deforms, achieving the purpose of grinding and pulverizing. After that, the second wedge plate 532 can detach from the first wedge plate 531, which facilitates the second wedge plate 532 to fit and extrude with the next set of first wedge plates 531 to grind the particles near the center of the liquid surface. This greatly shortens the stirring time while ensuring the stirring effect, thereby improving the efficiency of preparing diamond micron powder suspension.

[0045] Four circumferentially distributed fixed platforms 522 are fixedly connected to the upper side of the lower pressure plate 508. Each fixed platform 522 is fixedly connected to the upper side of a slide rod 523. Each slide rod 523 is slidably connected to the outside of a guide rod 524. The outside of each guide rod 524 is fixedly connected to the inner wall of the tank 1. Each slide rod 523 is fixedly connected to an air bladder 525. Each air bladder 525 is fixedly connected to a connecting piece 526 on the side away from the slide rod 523.

[0046] The bottom of the lower pressure plate 508 is provided with a slide 527 between two sets of water leakage grooves 512. A first wedge-shaped grinding seat 528 is slidably assembled in each set of slides 527. An airbag 529 is assembled between one side wall of the first wedge-shaped grinding seat 528 and the inner wall of the slide 527. A return spring 530 is assembled between the other side wall of the first wedge-shaped grinding seat 528 and the other inner wall of the slide 527. A second wedge-shaped grinding seat 533 matching the first wedge-shaped grinding seat 528 is fixed on the outer side wall of the inner tooth ring 518. Airbag 1 525 and airbag 2 529 correspond one-to-one. Each set of airbag 1 525 is connected to airbag 2 529 through an air supply pipe. An air intake one-way valve is fixedly assembled on each set of airbag 1 525. An exhaust solenoid valve is fixedly assembled on each set of airbag 2 529.

[0047] The top of the upper main crossbar 515 is fixed with a first wedge plate 531, and the bottom of the lower pressure plate 508 is fixed with a second wedge plate 532 that matches the first wedge plate 531. The second wedge plate 532 is a single-sided wedge seat. The first wedge grinding seat 528 and the second wedge grinding seat 533 are both double-sided wedge seats, and the second wedge grinding seat 533 and the second wedge plate 532 are both flexible sheets.

[0048] When the lowering rod 501 moves the lowering plate 508 downward, it can simultaneously move downward through the guide rod 524 and the connecting piece 526, thereby generating a squeezing force on the first airbag 525. This causes the first airbag 525 to be squeezed, and the gas inside the first airbag 525 will be introduced into the second airbag 529 through the air supply pipe. As a result, the second airbag 529 will inflate and expand, and after overcoming the rebound force of the return spring 530, it will push the first wedge-shaped grinding seat 528 to slide in the slide rail 527. During the sliding process, the first wedge-shaped grinding seat 528 and the second wedge-shaped grinding seat 533 will squeeze each other. The wedge-shaped squeezing force of the two can be used to crush the clumps floating on the liquid surface. During the squeezing process, when the first wedge-shaped grinding seat 528 squeezes the second wedge-shaped grinding seat 533, it can cause the second wedge-shaped grinding seat 533 to deform, so that the first wedge-shaped grinding seat 528 can pass over the second wedge-shaped grinding seat 533. This can collect and grind the particles and clumps at the outer edge of the liquid surface.

[0049] When the rotating rod 504 and the pressing rod 501 disengage, the guide rod 524 moves upward with the pressing plate 508. At this time, external air is supplied to the first airbag 525 through the one-way air inlet valve. The second wedge-shaped grinding seat 533 moves in the opposite direction in the slide 527 under the push of the return spring 530, which will squeeze the first wedge-shaped grinding seat 528 again, which can complete the secondary grinding process of liquid surface agglomeration. At the same time, the material remaining on the inclined surface of the grinding seat after grinding can be scraped off, which is convenient for the material to be mixed into the liquid. Moreover, when the second wedge-shaped grinding seat 533 moves back, it squeezes the second airbag 529, which causes the gas inside the second airbag 529 to be introduced into the liquid through the exhaust solenoid valve, thereby generating airflow in the liquid. This causes the powder clumps and particles that have not been incorporated into the liquid to float on the liquid surface with the airflow, which is convenient for grinding and crushing by the squeezing of the first wedge-shaped grinding seat 528 and the second wedge-shaped grinding seat 533. This can effectively prevent agglomeration during the preparation of suspension.

[0050] Please see Figures 6-7The tapping feeding module 6 includes four circumferentially distributed scraper bars 602, and a tapping rod 606 is provided on the outside of the scraper bars 602. A gear 601 is movably connected to the outside of the feeding hopper 4. The upper side of the gear 601 is fixedly connected to the bottom of the four scraper bars 602. The inner wall of the feeding hopper 4 is slidably connected to the outside of the four scraper bars 602. A motor 603 is fixedly connected to the upper side of the top cover 3. The output end of the motor 603 is connected to a gear 604 through a coupling. Gear 3 604 meshes with gear 2 601. A vertical shaft 605 is fixedly connected to the upper side of the top cover 3. A slot is opened on the striking rod 606. A coil spring 607 is fixedly connected to the inner wall of the slot. The end of the coil spring 607 away from the striking rod 606 is fixedly connected to the inner wall of the vertical shaft 605. The striking rod 606 is located outside the feeding hopper 4. An inclined block 608 is fixedly connected to the side of the striking rod 606 near the feeding hopper 4. The outside of the inclined block 608 contacts the outside of one of the scrapers 602.

[0051] During the process of pouring diamond powder into the feeding hopper 4, motor 3 603 is started. Motor 3 603 drives gear 2 601, which meshes with gear 3 604, to rotate. This allows scraper 602 to continuously scrape the powder off the inner wall of the feeding hopper 4. As gear 2 601 rotates, scraper 602 contacts inclined block 608. Scraper 602 pushes inclined block 608, causing striking rod 606 to overcome the torque of coil spring 607 and rotate away from the feeding hopper 4. After detachment, the energy-storing coil spring 607 quickly pulls back the striking rod 606, causing the striking rod 606 to strike the feeding hopper 4, thereby shaking off the micro powder attached to the feeding hopper 4. The striking feeding module 6 is mainly used in the striking feeding process. That is, the striking feeding module 6 uses the scraper 602 and the striking rod 606 to ensure the smoothness of the feeding hopper 4 when conveying diamond micro powder into the tank 1, avoiding micro powder residue or even blockage on the feeding hopper 4, and improving the feeding efficiency of the device.

[0052] As described above, the diamond micro powder suspension stirring device is used in bearing manufacturing. Using the diamond micro powder suspension stirring device can ensure the uniform distribution of diamond micro powder in the liquid, thereby improving the accuracy and efficiency of bearing processing. At the same time, it can provide uniform grinding force, making the bearing surface smoother, reducing surface unevenness, improving the bearing's operating performance, improving processing quality, extending bearing life, and reducing production costs.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
