Description

Technical Field

[0001] This invention belongs to the field of particle size detection technology, specifically a calcium carbonate particle size detection device. Background Technology

[0002] In the calcium carbonate production and processing industry, particle size detection is a key link to ensure product quality and directly affects its downstream application performance. Under large-scale production, continuous sample conveying and batch testing by conveying mechanisms has become the mainstream mode. Existing technologies often use bottom-up vibration to level the samples in the tray to adapt to the testing.

[0003] For example, Chinese patent application CN118583735A discloses a continuous powder particle size detection device and method. This technology uses continuously rotating first, second, and third shaking discs inside the conveyor belt to slightly shake the top and bottom of the conveyor belt, causing the powder to be shaken apart during conveying. The powder passing under the crossbar is absorbed through the suction pipe and suction box, thereby changing the amount of powder during conveying. Combined with the image captured by the camera, the content of particulate matter in the powder can be detected more accurately. Because calcium carbonate particles of different sizes have different masses, during vibration, larger particles are more likely to sink to the bottom of the tray due to gravity, while smaller particles tend to float to the surface. This results in uneven particle distribution in the sample, and the images collected by the subsequent testing agency can only reflect the particle size information of the small particles on the surface, failing to fully characterize the particle size distribution of the entire sample, thus causing distorted test results.

[0004] Secondly, if the vibration intensity is too low, it cannot effectively eliminate the accumulation and grooves on the sample surface, resulting in poor leveling and causing problems such as particle occlusion and incomplete contour recognition when the detection head acquires images. If the vibration intensity is too high, it will not only cause some calcium carbonate particles to break, producing false positive fine particles that interfere with particle size analysis results, but may also cause sample splashing in the tray, affecting the continuity and stability of the detection.

[0005] Therefore, the present invention provides a calcium carbonate particle size detection device. Summary of the Invention

A connecting cover is fixedly installed on the outer wall of the mounting box. An installation shaft is rotatably installed on the end of the connecting cover away from the mounting box. A flipping plate is fixedly installed on the radial outer wall of the installation shaft. The inner cavity of the mounting box is rotatably mounted with a drive shaft. The drive shaft is connected to the mounting shaft through a transmission component, and the drive shaft is connected to the control wheel through a right-angle gear ring.

[0011] Preferably, a drive wheel is rotatably mounted on the inner wall of the mounting box, and a control wheel meshes with the drive wheel. A sector wheel is rotatably mounted in the inner cavity of the mounting cylinder. The side wall of the striking rod has a toothed groove that mates with the sector wheel.

The combing rod rotates eccentrically with the mounting tray, and in conjunction with the sliding of the mounting box, it can achieve full-area agitation of the sample without dead corners, breaking the inertial distribution of particle accumulation. The turning plate flips the sample at the bottom of the tray to the surface, completely avoiding the stratification problem of large particles sinking and small particles floating. The tapping rod elastically taps the inner wall of the tray to generate gentle vibration, which can quickly eliminate the fine grooves in the sample after combing without causing particle crushing. The synergistic effect of the three components ensures that the sample always maintains its original uniform and flat shape, guaranteeing the integrity and authenticity of the images acquired by the detection head, ensuring the accuracy and reliability of data such as particle size measurement and distribution analysis, and significantly improving the consistency and data reference value of batch continuous detection.

[0015] 2. This invention, by incorporating a suction pump, a guide plate, and an elastic sheet, not only achieves efficient dust removal from the detection area but also establishes a linkage mechanism for suction, guide adjustment, and combing actions. The suction pump draws in dust through a suction hood, preventing dust from adhering to the detection head or mixing into the sample and interfering with detection accuracy. The elastic sheet reciprocates with the adjustment of the suction pump's power, automatically deflecting the guide plate via a connecting rod and transmission bar, dynamically adjusting the suction direction and improving dust removal efficiency in key areas. Simultaneously, the suction pump can drive the control plug inside the guide cylinder to slide back and forth, linking the control wheel to drive the combing rod to rotate. This allows for adaptive adjustment of the combing action without an additional power source, significantly improving equipment integration, reducing energy consumption, and enhancing the stability and adaptability of the device under long-term continuous detection conditions.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 10 As shown, the calcium carbonate particle size detection device of the present invention includes a conveying mechanism, a detection mechanism, a suction mechanism, a combing mechanism, and a leveling mechanism.

[0021] The conveying mechanism includes a conveyor 1 and a tray 9. The tray 9 is fixedly installed on the conveyor belt of the conveyor 1. The conveyor 1 consists of a frame, a conveyor belt, a tension roller and a motor. The tension roller is rotatably installed in the frame and is used to tension the conveyor belt. The motor controls the rotation of one of the tension rollers through the cooperation of the belt and pulley, thereby controlling the movement of the conveyor belt. During testing, the sample is placed inside the tray 9.

[0022] The testing mechanism includes a mounting cover 5, a mounting strip 11, and a testing head 10. The testing head 10 is fixedly mounted on the inner wall of the mounting cover 5 via the mounting strip 11. The mounting cover 5 is fixedly mounted on the upper end of the frame of the conveyor 1. When the tray 9 moves directly below the testing head 10, the testing head 10 performs full-coverage high-definition image information acquisition of the calcium carbonate sample in the tray 9. Subsequently, the acquired image data is transmitted to the matching data analysis terminal. The terminal system performs contour recognition, particle size measurement, quantity statistics, and distribution analysis on the calcium carbonate particles in the image. Finally, based on the preset particle size judgment standard, it generates the particle size test results and data report for this batch of calcium carbonate.

[0023] Multiple detection heads 10 are arranged along the conveying direction of the conveyor 1 to facilitate the collection of multiple sets of comparative data.

[0024] The suction mechanism includes a suction pump 8, a filter 4, and a suction hood 12. The suction pump 8 and the filter 4 are both fixedly installed on the outer wall of the mounting hood 5. The filter 4 is a common dust filter.

[0025] The suction hood 12 is fixedly installed on the outer wall of the mounting strip 11. The input end of the suction pump 8 is connected to the suction hood 12 through the filter 4. When the suction pump 8 is working, the negative pressure generated will suck up the dust on the surface of the conveyor belt and the dust inside the mounting hood 5. On the one hand, it can prevent dust from adhering to the surface of the detection head 10, ensuring the accuracy of high-definition image information acquisition, thereby improving the reliability of detection data such as calcium carbonate particle contour recognition and particle size measurement. On the other hand, it can prevent dust from falling into the sample in the tray 9, avoiding the interference of dust particles with the particle size detection results of calcium carbonate samples, ensuring that the detection data is consistent with the actual particle size of the sample. Finally, it can reduce the accumulation of dust on the conveyor belt, tension roller and other components of the conveyor 1, reduce the wear of dust on the operating parts of the equipment, and extend the service life of the conveyor 1 and the whole device.

[0026] The combing mechanism includes a mounting box 22, a mounting disc 27, and a combing rod 34, which are movably set inside the mounting cover 5. The mounting disc 27 is rotatably mounted on the bottom of the mounting box 22, and the combing rod 34 is fixedly mounted on the bottom surface of the mounting disc 27. When the mounting disc 27 rotates, it drives the combing rod 34 to rotate (the axis of the combing rod 34 is parallel to the axis of the mounting disc 27 and does not coincide with it).

[0027] After the previous image information acquisition, as the tray 9 moves to the bottom of the mounting box 22, the mounting box 22 is controlled to move until the combing rod 34 extends into the interior of the sample. At this time, the mounting box 22 is slidably adjusted to control the combing rod 34 to comb the calcium carbonate sample, while the mounting plate 27 is controlled to rotate to further comb the calcium carbonate sample inside the tray 9.

[0028] The mounting plate 27 drives the combing rod 34, whose axis is parallel to but not coincident with it, to rotate eccentrically. This enables multi-angle, dead-angle-free agitation and combing of the sample, effectively breaking up local accumulation of the sample and creating a uniform and flat foundation for subsequent image acquisition. The sliding adjustment of the mounting box 22 can drive the combing rod 34 to cover the entire area of ​​the tray 9, ensuring that samples in different positions within the tray 9 are fully combed, improving the overall coverage and consistency of sample flatness. This dynamic combing mode, which combines sliding and rotation, can avoid the squeezing damage to calcium carbonate particles caused by static combing, maintain the original shape of the particles, and prevent false positive data caused by particle breakage from interfering with subsequent particle size detection results.

[0029] The leveling mechanism includes a mounting cylinder 38 and a tapping rod 35. The mounting cylinder 38 is fixedly mounted on the outer wall of the mounting box 22, and the tapping rod 35 is elastically mounted on the outer wall of the mounting cylinder 38. When the combing rod 34 extends into the sample, the tapping rod 35 faces the two side walls of the tray 9. When the combing rod 34 combs, the tapping rod 35 taps the inner wall of the tray 9 from the inside to the outside, generating vibration, thereby reducing the grooves of the calcium carbonate sample after combing and achieving the leveling of the sample.

[0030] Eliminating local grooves and protrusions on the sample surface ensures that the calcium carbonate particles in tray 9 are evenly spread out, avoiding incomplete contour recognition caused by particle occlusion and stacking when the detection head 10 acquires images, thus improving the accuracy of particle size measurement. Vibration leveling ensures that the particle distribution density remains consistent, preventing statistical deviations caused by excessively dense or sparse particles in local areas, and ensuring that the particle size distribution report generated by the data analysis terminal is highly consistent with the actual sample conditions.

[0031] Compared to the method of directly vibrating and leveling from bottom to top without combing, this device can avoid the particle stratification problem caused by direct downward vibration. By actively combing to break up the accumulation and vibrating to level, it ensures that the particles in tray 9 are evenly distributed, improving the accuracy of image acquisition and particle size analysis by the detection head 10. At the same time, it avoids particle crushing caused by uncontrolled downward vibration. Gentle combing and elastic tapping can maintain the original shape of the particles, avoid false positive data interfering with the test results, improve the stability of continuous testing, and the combined action is highly controllable. It is adapted to the continuous conveying rhythm of conveyor 1, ensuring that the sample state in each tray 9 is consistent, and ensuring the repeatability and comparability of batch test data.

[0032] The inner wall of the mounting cover 5 is fixedly mounted with a slide rail 18, and the inner wall of the slide rail 18 is slidably mounted with a mounting block 23. The outer wall of the mounting block 23 is slidably fitted with the inner wall of the slide rail 18. The mounting box 22 is fixed to the bottom of the mounting block 23, and the mounting box 22 is controlled to slide synchronously by adjusting the mounting block 23.

[0033] A control rod 7 is fixedly installed on the outer wall of the mounting cover 5. The side wall of the slide rail 18 extends to the outer wall of the mounting cover 5 and is fixedly connected to the movable end of the control rod 7. The control rod 7 is a common electric telescopic rod. The slide rail 18 is raised and lowered by controlling the control rod 7, thereby controlling the raising and lowering of the mounting box 22, so that the combing rod 34 can be inserted into the tray 9 and away from the tray 9.

[0034] A connecting ear plate 19 is fixedly installed on the outer wall of the mounting block 23, and a transmission plate 20 is slidably installed on the outer wall of the connecting ear plate 19. The outer wall of the transmission plate 20 is slidably attached to the outer wall of the connecting ear plate 19.

[0035] A control screw 17 is rotatably mounted on the inner wall of the mounting cover 5. The control screw 17 passes through the transmission plate 20 and is connected to the transmission plate 20 through internal and external thread engagement. Rotating the control screw 17 causes the transmission plate 20 to slide, thereby controlling the sliding of the connecting ear plate 19 and the mounting block 23, so that the combing rod 34 can comb the sample. When the slide rail 18 is raised and lowered, the connecting ear plate 19 slides along the outer wall of the transmission plate 20.

[0036] A control motor 2 is fixedly installed on the outer wall of the mounting cover 5. The output shaft of the control motor 2 is fixedly connected to the axial end of the control screw 17. The control motor 2 drives the control screw 17 to rotate, thereby controlling the sliding of the mounting block 23.

[0037] In a preferred embodiment of the present invention, a control wheel 29 is rotatably mounted on the inner wall of the mounting box 22. The axial end of the control wheel 29 is fixedly connected to the outer wall of the mounting plate 27. The control wheel 29 is a gear. Rotating the control wheel 29 drives the mounting plate 27 to rotate, thereby controlling the rotation of the combing rod 34.

[0038] Multiple mounting discs 27 are evenly arranged along the bottom surface of the mounting box 22. Multiple mounting discs 27 rotate synchronously. The upper end of the mounting disc 27 is provided with a gear that meshes with the control wheel 29, so that rotating one mounting disc 27 drives the other mounting discs 27 to rotate synchronously.

[0039] The rotating mounting plate 27 drives the eccentric agitation of the combing rod 34 to create irregular grooves. Compared with straight grooves, these are easier to level during vibration leveling. The irregular intersecting grooves have no fixed direction of extension. When vibrating, the vibration waves generated by the elastic tapping of the tapping rod 35 against the inner wall of the tray 9 can act on the grooves from multiple directions, which can quickly push the particles to spread and fill the surrounding area. At the same time, the intersecting groove structure can disperse the vibration energy, avoid the energy being concentrated in a single direction and making it difficult to break the groove shape, and improve the leveling efficiency.

[0040] A connecting cover 25 is fixedly installed on the outer wall of the mounting box 22. A mounting shaft 26 is rotatably installed on the end of the connecting cover 25 away from the mounting box 22, and the connecting cover 25 provides installation and support for the mounting shaft 26.

[0041] A flipping plate 30 is fixedly installed on the radial outer wall of the mounting shaft 26. When the combing rod 34 slides in the sample, the mounting shaft 26 is rotated synchronously, which drives the flipping plate 30 to flip, thereby flipping the sample at the bottom of the tray 9 to the top, and then combing it by the combing rod 34. This avoids the defect of incomplete leveling caused by combing only the surface sample, and achieves uniform flatness of the entire sample layer. At the same time, it can effectively prevent the stratification phenomenon of large calcium carbonate particles settling at the bottom of the tray 9 and small particles concentrating on the surface, ensuring that the detection head 10 can cover particles of different sizes when acquiring images, and improving the comprehensiveness of particle size distribution analysis results. The inner cavity of the mounting box 22 is rotatably mounted with a drive shaft 28. The drive shaft 28 is connected to the mounting shaft 26 through a transmission component. The drive shaft 28 and the mounting shaft 26 are connected by a rubber ring. Rotating the drive shaft 28 drives the mounting shaft 26 to rotate. The drive shaft 28 is connected to the control wheel 29 through a right-angle gear ring. When the control wheel 29 rotates, it drives the drive shaft 28 and the mounting shaft 26 to rotate, thereby realizing the sorting of the sample while turning the material.

[0042] A transmission wheel 37 is rotatably mounted on the inner wall of the mounting box 22. A control wheel 29 meshes with the transmission wheel 37, and rotating the control wheel 29 drives the transmission wheel 37 to rotate synchronously.

[0043] The inner cavity of the mounting cylinder 38 is rotatably mounted with a sector wheel 36, which is a sector gear. The side wall of the striking rod 35 is provided with a tooth groove that mates with the sector wheel 36. The axial end of the transmission wheel 37 is connected to the axial end of the sector wheel 36 through a one-way bearing.

[0044] When the drive wheel 37 rotates, it will synchronously drive the sector wheel 36 to rotate. When the teeth of the sector wheel 36 are engaged with the groove of the striking rod 35, the thrust of the teeth will overcome the elastic force of the striking rod 35, pushing the striking rod 35 towards the inner wall of the tray 9 and completing the striking action. When the teeth of the sector wheel 36 rotate to the stage of disengaging from the groove of the striking rod 35, the striking rod 35 loses its thrust and then resets under the action of the elastic force. Through the continuous rotation of the sector wheel 36, combined with the reset action of the elastic force, the reciprocating continuous striking of the inner wall of the tray 9 by the striking rod 35 can be achieved.

[0045] In a preferred embodiment of the present invention, a control cylinder 32 is slidably mounted on the inner wall of the mounting block 23, and a transmission rod 33 is fixedly mounted on the axial end of the control wheel 29. One end of the transmission rod 33 extends to the inner wall of the control cylinder 32, and the outer wall of the transmission rod 33 slides against the inner wall of the control cylinder 32.

[0046] The radial outer wall of the transmission rod 33 is provided with a spiral groove, and the inner wall of the control cylinder 32 is fixedly installed with a ball 31 that slides with the spiral groove. Thus, when the control cylinder 32 slides back and forth, the transmission rod 33 and the control wheel 29 are controlled to rotate through the cooperation of the ball 31 and the spiral groove.

[0047] A guide cylinder 21 is fixedly installed on the outer wall of the mounting block 23. An adapter cylinder 6 is fixedly installed on the upper end face of the guide cylinder 21. A control plug 24 is elastically installed on the inner wall of the guide cylinder 21. The bottom surface of the control plug 24 is fixedly connected to the outer wall of the control cylinder 32. The reciprocating sliding control plug 24 drives the control cylinder 32 to slide synchronously.

[0048] The input end of the suction pump 8 is connected to the inner cavity of the adapter cylinder 6 through a conduit. The inner cavity of the filter 4 is connected to the adapter cylinder 6 through a conduit. The inner cavity of the adapter cylinder 6 is connected to the inner cavity of the guide cylinder 21. The output power of the suction pump 8 is adjusted back and forth, which in turn causes the air pressure of the guide cylinder 21 to be adjusted synchronously, which in turn causes the control plug 24 to slide back and forth, thereby realizing the rotation adjustment of the control wheel 29. A connecting pipe 3 is fixedly installed on the outer wall of the suction hood 12. One end of the connecting pipe 3 is connected to the inner cavity of the filter 4 through a conduit, thereby connecting the suction hood 12 and the filter 4.

[0049] The inner wall of the mounting strip 11 is rotatably mounted with a guide plate 16. Rotating and adjusting the guide plate 16 adjusts the suction direction and precisely controls the suction range and angle of the suction hood 12. It can be dynamically adjusted to target key dust areas around the detection head 10 and above the tray 9, avoiding ineffective suction and improving dust removal efficiency.

[0050] An elastic sheet 13 is fixedly installed on the outer wall of the suction shroud 12. When the output power of the suction pump 8 is adjusted, the elastic sheet 13 reciprocates.

[0051] A connecting rod 14 is fixedly installed on the side wall of the elastic plate 13, and a transmission bar 15 is fixedly installed on the other end of the outer wall of the connecting rod 14. A waist-shaped groove is opened on the side wall of the transmission bar 15, and a pin is installed at the upper end of the guide plate 16 that slides with the waist-shaped groove, wherein the pin passes through the waist-shaped groove.

[0052] When the elastic plate 13 reciprocates, it drives the transmission bar 15 to slide through the connecting rod 14, thereby controlling the guide plate 16 to deflect synchronously.
