Description

TECHNICAL FIELD

[0002] Flake graphite is a natural crystalline flaky graphite, which has unique flaky morphology and excellent physical and chemical properties, and is widely used in industries such as metallurgy, energy storage, and sealing. The particle size grading of flake graphite is a key indicator that determines the performance and application scenarios of the product, and is also a key detection item in the production and quality inspection process. Currently, the particle size detection of flake graphite in the industry generally uses a method of stacking multiple standard screens and vibrating screening. The sample to be tested is placed on the top of the stacked screen, and the particles are classified by size through vibration driving. The particles smaller than the screen hole pass through the screen layer by layer, and the particles larger than the screen hole are trapped in the corresponding screen. After screening, the materials in each layer are collected manually and placed on a weighing device equipped with an intelligent sensor. The weight of each particle size material is accurately collected by the intelligent sensor, and data transmission and basic calculation are automatically completed to obtain the particle size distribution results of the sample. This method is the current conventional technical means for flake graphite particle size detection.

[0026] The positioning ring 29 is fixedly installed on one side of the fixed frame 26, the negative pressure suction machine 30 is fixedly installed on the positioning ring 29, the input end of the negative pressure suction machine 30 is fixedly communicated with the stretching conduit 31, the one end of the stretching conduit 31 away from the negative pressure suction machine 30 is fixedly communicated with the one end of the collecting head 28, the auxiliary frame 33 is fixed on one side of the bottom end of the positioning ring 29, the tray 34 is fixedly installed on one side of the auxiliary frame 33, and the suction end of the collecting head 28 faces the inside of the corresponding collecting port 13.

[0027] The positioning ring 29 is fixed with a guide ring 32 away from one end of the collecting head 28, the bottom end of the guide ring 32 is clamped with a storage vessel 36, the bottom end of the tray 34 is fixed with a gravity intelligent sensor 35.

[0028] The output end of the negative pressure suction machine 30 is fixedly communicated with a discharge pipe 37, the output end of the discharge pipe 37 extends above the top end of the storage vessel 36, and the output end of the discharge pipe 37 is fixed with a baffle 38.

[0029] The top end of the second moving block 25 is symmetrically vertically fixed with two fixed rods 39, and the outer part of the two fixed rods 39 is fixed with a plurality of insulation plates 40 at equal intervals, and one end of each insulation plate 40 faces the gap between the adjacent two stainless steel sieve discs 6.

[0030] Working principle: when the device is used, first, a plurality of storage vessels 36 are clamped and installed at the bottom end of the guide ring 32, and the appropriate storage vessels 36 are placed on the upper part of the tray 34. This setting not only ensures the accurate collection and corresponding detection of each particle size material, but also allows the storage vessels 36 to be removed after detection for separate storage, enabling the device to be reused and avoiding sample cross-contamination, thereby providing a basic guarantee for the accuracy of the detection data. After preparation is completed, the flaky graphite samples to be detected are uniformly introduced into the topmost stainless steel sieve disc 6. After the introduction is completed, the electric telescopic rod 9 is started through the control box 3, the output end of the electric telescopic rod 9 drives the sealing cover plate 10 to vertically descend until the sealing cover plate 10 is tightly attached to the top end of the topmost stainless steel sieve disc 6, so that the plurality of stacked stainless steel sieve discs 6 are pressed and tightly closed, realizing the sealing protection of the screening process and avoiding the splashing and leakage of flaky graphite samples during the vibration screening process, thereby ensuring the stability of the total amount of the detection sample and laying a foundation for the accuracy of the subsequent particle size distribution calculation.

[0031] When the stainless steel sieve discs 6 are pressed against each other, the pressing block 16 is pressed by the pressing force of the adjacent stainless steel sieve discs 6 and slides vertically downward along the through hole 15. The pressing block 16 drives the strong magnet 17 fixed at the bottom end thereof to move downward synchronously, and the tension spring 18 is stretched and in a charged state. Since the adsorption end of the strong magnet 17 faces the ferrous scraper ring 19, the strong magnet 17 synchronously adsorbs the ferrous scraper ring 19 when it moves downward, driving the ferrous scraper ring 19 to slide vertically downward along the annular groove 12 until the ferrous scraper ring 19 completely blocks and closes the collecting port 13 at the bottom end of the stainless steel sieve disc 6, effectively preventing the flaky graphite sample from leaking from the collecting port 13 during the subsequent vibration screening process, ensuring that all samples participate in the screening operation, and eliminating the detection error caused by material loss.

[0032] After the sealing and collecting port 13 is closed, the vibration test table 4 is started through the control box 3, the vibration test table 4 drives the top several stainless steel sieve trays 6 to do vertical vibration and horizontal swing compound motion, the several stainless steel sieve trays 6 are sleeved and slidably installed outside the limiting rod 5 through the slide seat 7, are synchronously vibrated under the driving of the limiting rod 5, and the slide seat 7 can ensure that the stainless steel sieve trays 6 are not deviated and inclined in the vibration process, and the screening stability is ensured. Since the particle size screening plates 11 are fixed in each of the stainless steel sieve trays 6 except the bottommost one, and the mesh number of the particle size screening plates 11 increases from top to bottom, in the vibration process, the flaky graphite sample, the flaky particles with a particle size smaller than the screen hole of the corresponding particle size screening plate 11, penetrates the particle size screening plate 11 layer by layer and falls into the lower stainless steel sieve tray 6, and the particles with a particle size greater than the screen hole are intercepted in the corresponding stainless steel sieve tray 6, so that the flaky graphite is accurately graded according to the particle size, and the core operation of particle size screening is completed.

[0033] After the screening operation is completed, the electric telescopic rod 9 is recovered through the control box 3, the electric telescopic rod 9 drives the sealing cover plate 10 to vertically rise, the extrusion force between the plurality of stainless steel sieve trays 6 disappears, the tension spring 18 in the stretched state rebounds synchronously, drives the powerful magnet 17 and the pressing block 16 to vertically reset along the through hole 15, and the powerful magnet 17 resets synchronously to adsorb and drive the iron scraping ring 19 to reset upward along the annular groove 12. When the iron scraping ring 19 resets, the outer wall thereof is in close contact with and slides relative to the inner wall of the stainless steel sieve tray 6, can completely scrape off the flaky graphite particles adhered to the inner wall of the stainless steel sieve tray 6 in the screening process, avoids the detection error caused by the material residue, ensures that all the materials of each particle size participate in the subsequent collection and detection, guarantees that the detection data can truly reflect the particle size distribution of the sample to be tested, solves the pain points that the existing device is not completely cleaned by manual cleaning and the residual interferes with the detection, with the resetting of the iron scraping ring 19, the collecting port 13 is unblocked and completely opened, providing a channel for the collection of the materials of each particle size, at the same time, the annular groove 12 is in close contact with the iron scraping ring 19, ensuring that the outer wall of the scraping ring is in seamless contact with the inner wall of the stainless steel sieve tray 6; the outer wall surface of the iron scraping ring 19 is sprayed with a polytetrafluoroethylene wear-resistant coating, and the surface of the coating is mirror-polished, which not only improves the sealing property of the scraping ring and the inner wall of the sieve tray, completely scrapes off the small graphite particle residue, but also reduces the wear and tear caused by long-term friction, prolongs the service life of the scraping ring, and guarantees the long-term stability of the residue cleaning effect.

[0034] After the collection port 13 is opened, the stepper motor 23 is started, and the output end of the stepper motor 23 drives the double-threaded rod 21 to rotate. Since the first moving block 24 and the second moving block 25 are both threadedly sleeved and installed outside the double-threaded rod 21, and both penetrate and slide outside the auxiliary rod 22, the auxiliary rod 22 serves as a guide and limiting function, which can prevent the two moving blocks from rotating, so that when the double-threaded rod 21 rotates, the first moving block 24 and the second moving block 25 move synchronously and centrally along the double-threaded rod 21 and the auxiliary rod 22. When the first moving block 24 moves centrally, it drives the vertically fixed positioning frame 27 at the top of the first moving block 24 to move synchronously, and the positioning frame 27 drives the fixed collection head 28 outside the positioning frame 27 to move synchronously, until the suction end of each collection head 28 abuts into the corresponding collection port 13 of the stainless steel sieve disc 6, so as to ensure that all the materials in the corresponding sieve disc can be sucked in during the subsequent suction process, and to avoid material residues. At the same time, when the second moving block 25 moves centrally, it drives the two fixed rods 39 symmetrically fixed at the top of the second moving block 25 to move synchronously, and the two fixed rods 39 drive the plurality of insulating plates 40 fixed at equal intervals outside the two fixed rods 39 to move synchronously and centrally, so that one end of each insulating plate 40 is inserted into the gap between the adjacent two stainless steel sieve discs 6, realizing the isolation and sealing between the adjacent stainless steel sieve discs 6, avoiding the interference between different particle sizes of graphite particles during the subsequent suction process, preventing fine particle size particles from being sucked back to the upper level stainless steel sieve disc 6, and ensuring accurate separation of each particle size material, and further ensuring the accuracy of the detection data.

[0035] After the insulating plate 40 is in place and the collection head 28 precisely abuts against the collection port 13, the negative pressure suction machine 30 fixedly installed on the positioning ring 29 is started, the negative pressure suction machine 30 generates a negative pressure suction force when working, which is transmitted to the collection head 28 through the stretch conduit 31 fixedly communicated with the input end of the negative pressure suction machine 30, and the collection head 28 sucks all the specific particle size flaky graphite particles trapped in the corresponding stainless steel sieve disc 6 through the collection port 13, and the sucked materials enter the negative pressure suction machine 30 through the collection head 28 and the stretch conduit 31 in turn, and then are discharged through the discharge pipe 37 fixedly communicated with the output end of the negative pressure suction machine 30. The output end of the discharge pipe 37 extends above the top end of the storage vessel 36, and the baffle 38 fixedly installed at the output end of the discharge pipe 37 can prevent the materials from splashing when being discharged, so that each particle size material accurately falls into the corresponding clampingly installed storage vessel 36, realizing accurate collection of each particle size material, and the storage vessel 36 can be directly taken out for storage, which is convenient for subsequent re-inspection and traceability. At the same time, the negative pressure suction machine 30 is equipped with a frequency conversion control module, which can adjust the suction force according to the particle size of the materials in the stainless steel sieve disc 6, realizing efficient and residue-free suction of different particle size materials.

[0036] During the material collecting process, the bottom end of the tray 34 penetrates the fixed gravity intelligent sensor 35 to accurately collect the total weight of the corresponding storage vessel 36 and the internal material in real time. The gravity intelligent sensor 35 transmits the collected weight data to the control box 3 in real time. The control box 3 automatically deducts the weight of the storage vessel 36, calculates the net weight of each particle size material, and then automatically calculates, processes and feeds back the particle size distribution data according to the ratio of the net weight of each particle size material to the total weight of the sample to be tested, without manual material transfer, manual weighing and manual calculation. The integration of the scale graphite screening, cleaning, collecting, weighing and testing is completely realized, the manual intervention is greatly reduced, the detection errors caused by material spilling, cross contamination and residue during the manual splitting, brushing and transferring process of the existing device are avoided, and the detection efficiency and accuracy are significantly improved.
