Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Calcium carbonate powder is widely used in many industries such as chemical engineering, building materials, plastics, and papermaking, and its particle size directly affects the performance and quality of the products. Therefore, an efficient and accurate particle size detection device is crucial for precisely controlling the particle size of calcium carbonate powder.
[0028] This calcium carbonate powder particle size analyzer is ingeniously designed and complex, with several key components working in tandem to achieve accurate detection. The first part is the sample collection and delivery section, equipped with a specially designed sampler that penetrates deep into the calcium carbonate powder pile to collect samples uniformly and representatively. The sampler is connected to a sealed delivery pipe, which, through a cleverly designed spiral propulsion device, smoothly and quantitatively delivers the collected calcium carbonate powder to the detection area. This process ensures that the sample is not contaminated during delivery and enters the subsequent detection stages at a stable flow rate.
[0029] Moving into the testing phase, the most crucial part is the particle size analysis unit. This unit integrates multiple advanced testing technologies, among which the laser particle size analyzer is a key component. It operates based on the principle of light scattering. When a laser beam illuminates a calcium carbonate powder sample, powder particles of different sizes cause the laser light to scatter at different angles. The precision detector inside the laser particle size analyzer captures the angle and intensity information of this scattered light, and through complex and accurate algorithms, converts the light signal into particle size distribution data. For example, for smaller calcium carbonate powder particles, the scattered light angle is larger, while for larger powder particles, the scattered light angle is relatively smaller. The laser particle size analyzer can accurately distinguish and calculate the corresponding particle sizes.
[0030] Besides laser particle size analyzers, sieving devices also play a crucial role in particle size detection. They consist of a series of standard sieves with different mesh sizes, arranged in ascending order. Calcium carbonate powder samples are evenly distributed on the top sieve under the action of a vibrating device. As the vibration continues, powder particles that match the sieve mesh size gradually pass through and fall into the lower sieves, while larger particles remain on the current sieve. By accurately weighing the powder remaining on each sieve, the content of calcium carbonate powder in different particle size ranges can be calculated. This sieving method allows for intuitive classification and quantitative analysis of powders with different particle size ranges, providing important data for a comprehensive understanding of the particle size distribution of calcium carbonate powder.
[0031] To ensure the accuracy and stability of the test results, the device is equipped with an intelligent control system. This system monitors various parameters in real time through different sensors, such as the light source intensity of the laser particle size analyzer, the vibration frequency and amplitude of the sieving device, and the temperature and humidity of the sample. If any parameter deviates from its preset optimal value, the intelligent control system will quickly make adjustments. For example, if the system detects that the sample temperature has increased due to changes in the external environment, it will automatically activate the cooling device to adjust the sample temperature back to a suitable range, preventing temperature from affecting the powder particle size detection results.
[0032] This testing device demonstrates numerous significant advantages in practical applications. First, it boasts extremely high detection accuracy, precisely distinguishing between calcium carbonate powders of varying particle sizes, from nanometers to micrometers, providing reliable data support for the production of high-end products with stringent particle size requirements. Second, it offers rapid detection, significantly shortening the testing cycle and improving production efficiency compared to traditional methods. In enterprises that mass-produce calcium carbonate powder or use it as a raw material, rapid testing results allow for timely adjustments to production processes, ensuring product quality stability. Furthermore, the device is easy to operate and highly automated. Operators only need to perform simple sample collection and startup operations; the subsequent testing process is completed automatically, reducing human error and lowering the skill requirements for operators.
[0033] However, like any advanced technological equipment, this calcium carbonate powder particle size analyzer faces several challenges in its development. On one hand, the manufacturing cost is high. The use of advanced laser technology, precise sieving devices, and a complex intelligent control system makes the equipment relatively expensive, limiting its widespread application in some small businesses. On the other hand, for some calcium carbonate powders with special properties, such as those with strong adsorption or easy agglomeration, particle agglomeration may occur during the detection process, affecting the accuracy of the results. This necessitates further optimization of the detection method or the addition of special dispersants to address these issues.
[0034] Looking ahead, with continuous technological advancements, calcium carbonate powder particle size analysis devices are expected to achieve even greater development. In terms of technological innovation, more advanced detection principles and methods may be developed, further improving detection accuracy and speed while reducing equipment costs. For example, nanotechnology could be used to develop more sensitive sensors capable of more accurately detecting calcium carbonate powder with extremely fine particle sizes. In terms of application expansion, this device will not only find wider application in traditional industries such as chemicals and building materials, but may also play a significant role in emerging fields such as nanomaterials and biomedicine, providing strong technical support for product development and quality control in these areas and driving the rapid development of related industries.
[0035] Please see Figure 1-2 As shown, this embodiment provides a calcium carbonate powder particle size detection device, including: a base 1, an adjustment groove in the base 1, a power component in the adjustment groove, the upper part of the power component extending to the outside of the base 1, a receiving component mounted on the power component, a fine sieve component mounted on the receiving component, a coarse sieve component mounted on the fine sieve component, and a discharge component on the side of the receiving component, the fine sieve component, and the coarse sieve component.
[0036] The power assembly includes multiple lifting rods 6, the upper part of which extends to the outside of the base 1. The lifting rods 6 are installed on the lower end face of the receiving assembly. A circular plate 7 is installed on the lower end face of the lifting rods 6. A movable wheel 8 is provided at the bottom of the circular plate 7. A motor 2 and multiple support columns 5 are installed on the lower side of the adjustment groove. The motor 2 is located between the multiple support columns 5. The output shaft of the motor 2 is fixedly connected to a turntable 3. The movable wheel 8 is located on the upper end face of the turntable 3. The turntable 3 rotates and engages with the upper end face of the multiple support columns 5. Multiple fixing blocks 4 are installed on the upper end face of the turntable 3. The vertical cross-section of the fixing blocks 4 is a right-angled trapezoidal structure.
[0037] One application of this embodiment is as follows: In use, calcium carbonate powder is first poured into the coarse sieve assembly. Then, the motor 2 is started, driving the turntable 3 to rotate under the support of the support column 5. This causes the fixed block 4 on the turntable 3 to rotate accordingly. The rotation of the fixed block 4 uses the inclined plane to push the moving wheel 8 to roll on the surface of the turntable 3, thereby driving the circular plate 7 and the lifting rod 6 to rise and fall periodically. This, in turn, causes the receiving assembly, fine sieve assembly, and coarse sieve assembly to vibrate up and down as a whole. During the vibration, the coarse sieve assembly first separates the larger calcium carbonate powders. The unscreened powder falls into the fine sieve assembly below for secondary screening. The remaining ultrafine calcium carbonate powder finally falls into the receiving assembly at the bottom. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.
[0038] By cooperating with the motor 2 and the turntable 3, the rotation of the fixed block 4 forces the moving wheel 8 to rise and fall, causing the lifting rod 6 and the receiving assembly, fine sieve assembly and coarse sieve assembly to vibrate regularly, which facilitates multi-level particle size screening of calcium carbonate powder and improves screening efficiency. The stacked structure of the coarse sieve assembly, fine sieve assembly and receiving assembly, together with the side discharge assembly, improves the convenience of multi-stage calcium carbonate powder sorting and collection.
[0039] like Figure 2 As shown, the upper side of the base 1 in this embodiment is provided with a slot corresponding to the lifting rod 6. The slot is connected to the adjustment slot, and the lifting rod 6 passes through the slot. The slot reduces the probability of the base 1 obstructing the sliding of the lifting rod 6.
[0040] like Figure 2As shown, in this embodiment, two support plates 9 are installed on the lower end face of the circular plate 7, and an extension rod is provided between the two support plates 9. The movable wheel 8 is rotatably engaged with the periphery of the extension rod. The cooperation between the support plates 9 and the extension rod facilitates the improvement of the rotation stability of the movable wheel 8.
[0041] like Figure 2 As shown, the lower end face of the turntable 3 in this embodiment is provided with an annular groove, and the upper part of the support column 5 is located in the annular groove. The annular groove and the support column 5 cooperate to improve the stability of the turntable 3 when rotating and reduce the probability of the turntable 3 shifting when the equipment vibrates.
[0042] like Figure 2 As shown, in this embodiment, the receiving assembly, fine sieve assembly, and coarse sieve assembly are all equipped with discharge hoppers 10 on their sides. The inner walls of the discharge hoppers 10 are provided with guide grooves on both sides, which penetrate the upper side of the discharge hoppers 10. A baffle plate 11 is slidably fitted inside the discharge hoppers 10, with its two sides slidably fitted in the corresponding guide grooves. The discharge hoppers 10 and the baffle plates 11 are in contact with the sides of the corresponding receiving assembly, fine sieve assembly, or coarse sieve assembly. A lever 12 is provided on one side of the baffle plate 11. The guide grooves improve the stability of the baffle plate 11 when it slides up and down in the discharge hoppers 10, and the lever 12 improves the ease of sliding of the baffle plate 11. The baffle plate prevents the calcium carbonate powder in the corresponding coarse sieve assembly, fine sieve assembly, or receiving assembly from sliding out, so that the calcium carbonate powder can be fully screened, thereby improving the screening effect of the screening device on the calcium carbonate powder.
[0043] like Figure 2 As shown, the receiving assembly of this embodiment includes a first ring cylinder 13 and a bottom plate 14. The lifting rod 6 is installed on the lower end face of the bottom plate 14. The first ring cylinder 13 is installed on the periphery of the bottom plate 14. The side of the first ring cylinder 13 is provided with a discharge port corresponding to the discharge hopper 10. The bottom plate 14 is inclined toward the discharge port. The ultrafine calcium carbonate powder is intercepted by the bottom plate 14, so that the ultrafine calcium carbonate powder stays in the first ring cylinder 13.
[0044] like Figure 2 As shown, the fine sieve assembly of this embodiment includes a second annular cylinder 15 and a primary sieve 16. The second annular cylinder 15 is installed on the upper end face of the first annular cylinder 13 and is installed around the primary sieve 16. The side of the second annular cylinder 15 is provided with a discharge port 2 corresponding to the discharge hopper 10. The primary sieve 16 is inclined toward the discharge port 2. The calcium carbonate powder is intercepted by the primary sieve 16, so that the calcium carbonate powder stays in the second annular cylinder 15.
[0045] like Figure 2As shown, the coarse screening assembly of this embodiment includes a third ring cylinder 17 and a secondary screen 18. The third ring cylinder 17 is installed on the upper end face of the second ring cylinder 15 and is installed on the periphery of the secondary screen 18. The screen hole diameter of the secondary screen 18 is larger than that of the screen hole diameter of the primary screen 16. The side of the third ring cylinder 17 is provided with a discharge port 3 corresponding to the discharge hopper 10. The larger calcium carbonate powder is intercepted by the secondary screen 18, so that the larger calcium carbonate powder stays in the third ring cylinder 17.
[0046] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
