Description

Technical Field

[0001] This invention relates to the field of trace element detection technology, specifically to a rapid detection device for trace elements in calcined petroleum coke used in the production of anode materials. Background Technology

[0002] Calcined petroleum coke is a carbon material produced by calcining petroleum coke at a high temperature of around 1300℃. Petroleum coke is a black or dark gray hard solid with a metallic luster and porous structure. Its components include carbon and hydrogen, as well as nitrogen, chlorine, sulfur, and heavy metal compounds. Calcination removes volatiles, increases the degree of graphitization, and enhances conductivity and high-temperature strength. It is widely used in graphite electrodes, aluminum electrolytic anode paste, and the metallurgical industry.

[0003] Current methods for detecting trace elements in calcined petroleum coke mostly involve manual offline sampling followed by laboratory testing with a spectrometer. This method has several drawbacks: First, the testing process is cumbersome and time-consuming, with the entire process of manual sampling, sample preparation, and testing taking a long time, making it difficult to meet the real-time quality control requirements of large-scale production of anode materials. Second, the sample representativeness is poor, as the particle size distribution of the dust-like particles generated during the processing of calcined petroleum coke is uneven, and random manual sampling cannot cover particles of different sizes, easily leading to significant deviations between the test results and the actual raw material conditions. Third, the samples are easily contaminated, as the particles can easily come into contact with the external environment during manual sampling, introducing impurities that affect the accuracy of the test.

[0004] To address the aforementioned problems, this invention designs a rapid detection device for trace elements in calcined petroleum coke used in the production of anode materials, enabling the sampling and rapid detection of trace elements in calcined petroleum coke and overcoming the shortcomings of existing technologies.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This rapid detection device for trace elements in calcined petroleum coke used in the production of negative electrode materials employs a conical layered nested structure in its filtration mechanism. Combined with filter pores that gradually decrease in size from the inside out, it can intercept petroleum coke particles of different sizes in layers. Simultaneously, the grooves in the collection tank correspond one-to-one with the gaps in the conical cylinder, achieving layered collection of particles of different sizes. This allows for precise analysis of the distribution characteristics of trace elements at different particle sizes, improving the comprehensiveness of the detection.

[0040] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0041] like Figure 1-10 As shown, a rapid detection device for trace elements in calcined petroleum coke used in the production of negative electrode materials includes an exhaust assembly 1, a filtration mechanism 2, a collection mechanism 3, a collection mechanism 4, a conveying mechanism 5, a grinding assembly 6, a monitoring unit 7, and a control system 8. The various mechanisms work together to achieve stratified collection, sample processing, and rapid detection of calcined petroleum coke particles.

[0042] The exhaust assembly 1 guides gas flow. The filter mechanism 2 is located inside the exhaust assembly 1 and is arranged in layers. The collection mechanism 3 includes a drive unit 31 and a collection component 32. The drive unit 31 is located at the upper end of the filter mechanism 2, and the collection component 32 is fixedly connected to the drive unit 31 and is located in the interlayer of the filter mechanism 2. The collection mechanism 4 is located below the filter mechanism 2 and includes a collection groove 41 and a release baffle 42. The transport mechanism 5 is located below the collection mechanism 4 and is used to transport the collected sample. The grinding assembly 6 is used to grind and flatten the sample. The monitoring unit 7 includes a detection spectrometer 71 and a position sensor 72. The detection spectrometer 71 is located above the transport mechanism 5 to detect the sample, and the position sensor 72 is used to monitor the position of the sample. The control system 8 includes a display assembly 81 and a control panel 82. The display assembly 81 is used to display the detection results, and the control panel 82 is responsible for the coordinated control between the components.

[0043] In an optional embodiment, the filter mechanism 2 is generally conical in shape and is composed of several sets of conical cylinders that are nested together. There is a gap between adjacent nested conical cylinders. The surface of the conical cylinder is provided with filter holes. The diameter of the filter holes on the outer conical cylinder surface is smaller than the diameter of the filter holes on the inner conical cylinder.

[0044] In this embodiment, the conical structure design can work with the centrifugal motion of the airflow to create a swirling flow of dust-laden air inside the filter mechanism 2, making it easier for particles to come into contact with the surface of the conical cylinder for filtration. The gradually decreasing diameter of the filter holes from the inside to the outside enables the graded interception of particles. The large-diameter conical cylinder on the inside intercepts large-diameter petroleum coke particles, while the small-diameter conical cylinder on the outside intercepts small-diameter particles, achieving stratified separation of particles of different sizes and providing a basis for subsequent stratified detection. At the same time, the layered structure makes the overall structure of the filter mechanism 2 compact, occupies little space, and is suitable for the site requirements of industrial production.

[0045] In an optional embodiment, the drive unit 31 includes a power box 311 and a drive gear set 312, the drive gear set 312 being composed of several sets of gears, the power box 311 being fixedly connected to the drive gear set 312 and providing rotational power.

[0046] In this embodiment, the power box 311 serves as a power source, providing stable and adjustable rotational power to ensure that the rotational speed of the active gear set 312 is controllable. The multiple gears of the active gear set 312 are evenly distributed and precisely mesh with the gear ring of the collection component 32. At the same time, the gear transmission method has high transmission efficiency and strong stability, which can adapt to the long-term continuous working requirements in industrial production and provide reliable power support for the rotational cleaning action of the collection component 32.

[0047] In an optional embodiment, the collection component 32 includes a push ring 321 and a collection rod 322. The lower end of the push ring 321 is an annular plate, which is in rotatable contact with the upper end face of the conical cylinder of the filter mechanism 2. A toothed ring is fixedly connected to the upper surface of the annular plate, and the toothed ring meshes with the drive gear set 312. The collection rod 322 is fixedly connected to the lower surface of the annular plate of the push ring 321. The outer surface of the collection rod 322 is in sliding contact with the surface of the conical cylinder of the filter mechanism 2. The collection rod 322 is located between the gaps of the conical cylinders that are nested in layers.

[0048] In this embodiment, the rotating design of the annular plate of the pushing ring 321 and the upper end face of the conical cylinder can promote the stability of the rotation of the ring 321. The collection rod 322 adopts a structure combining wear-resistant rubber and metal rod. Its outer surface is closely attached to the surface of the conical cylinder. When rotating with the pushing ring 321, it can effectively scrape off the particles attached to the surface of the conical cylinder and the filter holes, avoiding the filter holes from being blocked and affecting the filtration efficiency. At the same time, the collection rod 322 is located between the gaps of the conical cylinder and will not collide with the conical cylinder during rotation, ensuring the stability of the equipment operation. The scraped particles can fall directly into the collection mechanism 4 below, realizing the efficient collection of particles.

[0049] In an optional embodiment, the conveying mechanism 5 includes a conveying belt 51, a conveying ring 52, and a linkage tooth 53. The conveying belt 51 is U-shaped and has a detection box 511 and a monitoring block 512 on its upper surface. The monitoring block 512 facilitates the position sensor 72 to sense and detect the rotational position of the conveying belt 51. A toothed belt is provided at the lower end of the conveying belt 51. The surfaces on both sides of the linkage tooth 53 are engaged with the conveying ring 52. The outer surfaces of both sets of conveying rings 52 are engaged with the toothed belt of the conveying belt 51. One set of conveying rings 52 is rotatably connected to the lower outer wall of the exhaust assembly 1.

[0050] In this embodiment, the conveyor belt 51 features a continuous annular transport design, enabling it to adapt to the switching requirements of multiple workstations such as testing and grinding. Detection boxes 511 are distributed on the conveyor belt 51, and the number of detection boxes 511 matches the number of conical slits in the filter mechanism 2, allowing for the separate holding of particles of different sizes and preventing sample mixing. The monitoring block 512 is a magnetic induction block that precisely cooperates with the sensing end of the position sensor 72, enabling precise positioning of the conveyor belt 51's movement and ensuring that the detection box 511 can accurately stop directly below the grinding assembly 6 and the detection spectrometer 71. The meshing design of the linkage tooth 53 with the two sets of conveyor rings 52 enables the synchronous rotation of the two sets of conveyor rings 52, thereby driving the toothed belt of the conveyor belt 51 to move smoothly and preventing problems such as deviation or slippage of the conveyor belt 51.

[0051] In an optional embodiment, the collection tank 41 is circular in shape, and several sets of conical cylinders of the filtering mechanism 2 are fixedly installed at the upper end of the collection tank 41. The upper surface of the collection tank 41 is provided with an annular groove, which corresponds to the gap between two sets of adjacent conical cylinders. The lower surface of each set of grooves is provided with holes at different positions to facilitate the falling of samples in the groove. The collection rod 322 is slidably connected to the inner wall of the groove of the collection tank 41.

[0052] In this embodiment, the annular collection groove 41 is adapted to the conical filter mechanism 2, enabling all-round collection of particles falling from different conical gaps; the annular chute corresponds one-to-one with the conical gap, allowing particles of different sizes to fall into the corresponding chute, achieving stratified temporary storage of particles and preventing mixing of particles of different sizes; the holes on the lower surface of the chute allow particles to fall into the detection box 511 below, ensuring the sampling effect; the sliding connection design between the collection rod 322 and the inner wall of the chute allows the collection rod 322 to scrape off the particles attached to the inner wall of the chute while rotating, preventing particles from accumulating in the chute and ensuring that particles can fall smoothly, while the sliding connection does not affect the normal rotation of the collection rod 322.

[0053] In an optional embodiment, a release baffle 42 is disposed on the surface of the hole at the lower end of the collection tank 41. The release baffle 42 rotates around the connecting shaft. A motor is disposed on the end face of the connecting shaft of the release baffle 42, and the motor is controlled by the control panel 82.

[0054] In this embodiment, the release baffle 42 can completely block and open the hole by rotating, thereby controlling the timing of the sample fall.

[0055] In an optional embodiment, the grinding assembly 6 includes a rotating tooth 61, a telescopic rod 62, and a grinding rod 63. The rotating tooth 61 is driven by a motor to rotate the grinding assembly 6. The telescopic rod 62 is fixedly connected to the end face of the rotating tooth 61 and is used to drive the grinding rod 63 to move up and down. The grinding rod 63 corresponds to the size and position of the detection box 511.

[0056] In this embodiment, the rotating tooth 61 is a gear structure that meshes with the output gear of the drive motor. The motor can provide adjustable speed rotational power to realize the rotation of the grinding rod 63. The telescopic rod 62 is an electro-hydraulic telescopic rod, which can adjust the descent height of the grinding rod 63 according to the depth of the detection box 511 to avoid hard collision between the grinding rod 63 and the detection box 511. When rotating, the grinding rod 63 can perform all-round grinding and flattening of the particles in the detection box 511, so that the particles form a uniform and flat detection surface, eliminating the deviation of the detection results of the detection spectrometer 71 caused by particle accumulation and unevenness, and improving the detection accuracy.

[0057] In an optional embodiment, the exhaust assembly 1 includes a guide shell 11 and an exhaust fan blade 12. The guide shell 11 is a frustoconical hollow shell with a vent hole at the upper end. A housing is connected to the outside of the guide shell 11, and the housing wraps around the outside of the conveying mechanism 5 and the monitoring unit 7. A gap is left between the inner wall of the guide shell 11 and the filter mechanism 2. The lower end of the guide shell 11 is fixedly connected to the collection tank 41. The exhaust fan blade 12 is located at the upper end of the inner side of the guide shell 11 and is connected to the output end above the power box 311.

[0058] In this embodiment, the frustum-shaped air guide shell 11 can guide the airflow, so that the airflow passing through the filter mechanism 2 flows upward along the inner wall of the air guide shell 11, reducing the resistance during the airflow process, improving the airflow efficiency, and thus ensuring the filtration effect of the filter mechanism 2; the exhaust fan blade 12 can control the airflow speed and adapt to the filtration requirements of different concentrations of dust-laden airflow.

[0059] When in use, first connect the exhaust pipe of the calcined petroleum coke in the production process of negative electrode material to the lower end of the guide shell 11 of the exhaust component 1 of this device. By operating the control panel 82, the power box 311 drives the exhaust fan blade 12 to rotate, which accelerates the flow of gas, so that the airflow enters the inner side of the guide shell 11 from the inside of the filter mechanism 2 through the filter hole and is discharged from the top.

[0060] The filter mechanism 2 gradually narrows its filter holes, allowing particulate matter trapped in the airflow to be intercepted and filtered. The power box 311 drives the drive gear set 312 to rotate, which in turn drives the push ring 321 to rotate. This causes the collection rod 322 to rotate inside the filter mechanism 2, clearing dust particles blocked by the filter holes. The dust particles fall into the collection tank 41. The control system 8 controls the motor to drive the release baffle 42 to rotate, causing the dust particles to fall into the detection box 511 above the conveyor belt 51 for sample collection. Different detection boxes 511 hold particles filtered by filter holes of different diameters, and multiple sets of different samples are collected for testing.

[0061] Then, the control system 8 controls the motor to drive the linkage gear 53 to rotate, which in turn drives the two sets of transport rings 52 to rotate. The transport rings 52 rotate simultaneously, which in turn drives the transport belt 51 to rotate. The rotation of the transport belt 51 moves the detection box 511. The position sensor 72 and the monitoring block 512 work together to control the movement of the detection box 511, so that the detection box 511 is moved directly below the grinding assembly 6. The telescopic rod 62 is activated to extend the grinding rod 63 into the inside of the detection box 511. The motor drives the rotating gear 61 to rotate, so that the grinding rod 63 rotates and flattens the sample inside the detection box 511. After the grinding assembly 6 is retracted, the transport belt 51 moves, so that the detection boxes 511 are moved one by one directly below the detection spectrometer 71. The trace elements inside the detection box 511 are detected one by one. The side of the shell is provided with an openable side door. After detection, the detection box 511 is removed and replaced to facilitate the next sample collection and detection.
