Description

Technical Field

[0001] This invention relates to the field of mineral composition detection technology, and in particular to a full-element bypass mineral composition analyzer. Background Technology

[0002] In mineral processing, coal utilization, and geological exploration, the elemental composition and core indicators of minerals, such as ash content, moisture, sulfur content, and calorific value in coal mines, are crucial for determining mineral quality grading, processing technology selection, and utilization value assessment. Accurate and efficient testing data plays an irreplaceable guiding role in production process optimization, product quality control, and safe production. With the increasing level of industrial automation, traditional mineral composition testing methods are gradually becoming insufficient to meet the demands of modern production for timely, stable, and intelligent testing.

[0003] Currently, mineral composition detection largely relies on a combination of offline sampling and laboratory analysis. In this model, operators manually collect material samples from the production site and then transport them to a dedicated laboratory for compositional analysis using large-scale testing equipment. Because the time interval between sampling and testing is long, typically several hours or even longer, the test results lag behind the production process, preventing timely feedback to the production system for real-time control. In recent years, to address the lag issue of offline detection, online detection devices have been explored. However, most online detection devices operate in an open, atmospheric pressure environment, where dust, water vapor, carbon dioxide, and other components in the air easily interact with the detection signal, leading to a significant decrease in detection accuracy. Furthermore, the system integration is low; sampling, transportation, and detection are independent processes requiring manual intervention, preventing the formation of an automated detection workflow and further exacerbating detection lag and human error. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a full-element bypass mineral composition analyzer to solve the issues of detection lag, low automation, and low detection accuracy in existing mineral composition detection technologies.

[0005] This invention is implemented as follows: A full-element bypass mineral composition analyzer includes a sampling unit, a detection unit, and a control unit. The sampling unit includes a material box for real-time material collection, which is transported to a sealing unit via a transfer unit. The detection unit includes a vacuum detection chamber and a full-element mineral composition analyzer. The vacuum detection chamber has a detection inlet, and the sealing unit slides through the detection inlet. The sealing unit transports the material box into the vacuum detection chamber and seals the chamber. A negative pressure pump is connected to the outside of the vacuum detection chamber via a pipeline. The negative pressure pump is used to extract air from the chamber. The control unit is signal-connected to the negative pressure pump.

[0006] Furthermore, the sampling unit includes a sampling chamber with a hollow interior. The top of the sampling chamber has an inlet, and the bottom has an outlet. A door is rotatably mounted on one side of the sampling chamber. A leveling device is fixed inside the sampling chamber, positioned near and above the door.

[0007] Furthermore, the transfer unit includes a first guide rail, one end of which is positioned opposite to the detection inlet. A first slider is slidably mounted on the first guide rail, and a rotating platform is fixedly mounted on the top of the first slider. An electric gripper is fixedly mounted on the top of the rotating platform.

[0008] Furthermore, it also includes a fixed frame, with a long mounting plate on the top of the fixed frame, and second guide rails symmetrically arranged on both sides of the long mounting plate, with second sliders slidably mounted on the second guide rails.

[0009] Furthermore, the vacuum testing chamber is fixedly installed at one end of the top of the long strip mounting plate, and a vertical mounting plate is fixedly installed at the other end of the long strip mounting plate. A support frame is fixedly connected to the vertical mounting plate, and an electric push rod is fixedly installed on the support frame. The movable end of the electric push rod is connected to a sliding plate, and the sliding plate is fixedly connected to two second sliders.

[0010] Furthermore, the sealing unit includes a sealing top core and a dustproof plate, which are fixedly connected by a bracket. The sealing top core is fixedly connected to the slide plate and is located on the side of the slide plate away from the electric push rod.

[0011] Furthermore, the sealing core includes a first column, one end of which is provided with a stop plate, and the other end is provided with a conical structure and fixedly connected to one end of the bracket. The outer wall of the first column is provided with several grooves, and sealing rings are installed in the grooves.

[0012] Furthermore, the dustproof plate includes a second column and a third column arranged coaxially, with one end of the second column fixedly connected to the other end of the bracket.

[0013] Furthermore, the bracket has a U-shaped structure, and a magnet is fixed in the middle of the bottom wall of the bracket. A magnetic absorbing piece is correspondingly provided at the bottom of the material box, and the magnet and the magnetic absorbing piece are magnetically attracted to each other.

[0014] Furthermore, filters are also installed on the pipeline.

[0015] The beneficial effects of this invention are: The all-element bypass mineral composition analyzer of this invention integrates a sampling unit, a transfer unit, a sealing unit, and a detection unit. The control unit enables automated and coordinated operation of each component, eliminating the need for manual intervention and effectively shortening the interval between sampling and detection, thus improving detection efficiency. The outer wall of the sealing top core is equipped with multiple sets of sealing rings, which, combined with the guiding effect of the conical structure, ensure a tight fit with the detection inlet of the vacuum detection chamber, guaranteeing the vacuum level of the detection environment. Simultaneously, the dustproof plate effectively prevents external dust from entering, further optimizing the detection environment and improving detection accuracy. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1 The diagram shows the all-element bypass mineral composition analyzer of the present invention, which includes a sampling unit 1, a detection unit 2, and a control unit (not shown in the figure). The sampling unit 1 includes a material box 11 for real-time material collection. The material box 11 is transported to the sealing unit 4 through a transfer unit 3. The detection unit 2 includes a vacuum detection chamber 21 and an all-element mineral composition analyzer 22. The vacuum detection chamber 21 has a detection inlet 211. The sealing unit 4 is slidably inserted into the detection inlet 211. The sealing unit 4 transports the material box 11 into the vacuum detection chamber 21 and seals the vacuum detection chamber 21. The outside of the vacuum detection chamber 21 is connected to a negative pressure pump 5 through a pipeline. The negative pressure pump 5 is used to extract the air inside. The control unit is signal-connected to the negative pressure pump 5.

[0020] like Figure 2 As shown, the sampling unit 1 includes a sampling chamber 12, which has a hollow internal structure. The top of the sampling chamber 12 has an inlet 121, and the bottom has an outlet 122. The inlet 121 is used to receive the material to be tested. The top of the inlet 121 has a connecting flange that can connect to an on-site material chute or be combined with an on-site conveying device to guide the material into the inlet 121. The outlet 122 is located at the bottom of the sampling chamber 12 and is used to discharge excess material. The bottom of the outlet 122 can be connected to an on-site waste disposal device or a sample collector 13. The sampling chamber 12 can be combined with an on-site material receiving device or can be supplied by a material divider, facilitating the provision of material sources to the testing system. A door 14 is rotatably mounted on one side of the sampling chamber 12. After the door 14 is opened, the material box 11 can enter the sampling chamber 12 to receive the material to be tested. In this embodiment, the door 14 can be opened by a pulley, controlled by an electric push rod 66, or controlled by a servo motor. The opening and closing method of the door 14 can be any of the aforementioned prior art methods, and no limitation is imposed here. The material box 11 is a cuboid structure with an open top, used for holding materials.

[0021] like Figure 3The diagram shows only the positional relationship between the leveling device 15, the door 14, and the material box 11 within the sampling chamber 12. The leveling device 15 is fixedly installed inside the sampling chamber 12, positioned near and above the door 14, and is used to level the material inside the material box 11. The leveling device 15 includes a first fixing seat 151, one side of which is bolted to one side of the inner wall of the sampling chamber 12. A second fixing seat 152 and a third fixing seat 153 are sequentially provided on the other side of the first fixing seat 151, and these three fixing seats are fastened together with bolts. The first fixing seat 151 has a U-shaped structure, with its outer bottom wall fixedly connected to the inner wall of the sampling chamber 12. A first scraper 154 is bolted to the inner side of its bottom wall. The bottom of the first scraper 154 has a notch, the top wall of which abuts against the top of the material box 11, and the two side walls of which abut against the two side walls of the material box 11. The second fixing seat 152 and the third fixing seat 153 have the same structure, both being I-shaped. A second scraper 155 is fixedly connected to the second fixing seat 152 by bolts. The bottom wall of the second scraper 155 has a conical structure, and the bottom of the second scraper 155 abuts against the top surface of the material box 11. The width of the second scraper 155 is the same as the width of the material box 11. A third scraper 156 is fixedly connected to the third fixing seat 153 by bolts. The bottom of the third scraper 156 also has a conical structure, and the side wall of the third scraper 156 abuts against the inner wall of the material box 11. The bottom of the third scraper 156 extends downward into the material box 11, and its bottom surface is slightly lower than the top surface of the material box 11. The first scraper 154, the second scraper 155, and the third scraper 156 are spaced apart, forming a progressive leveling operation of positioning, coarse scraping, and fine scraping. Specifically, the first scraper 154 abuts against the wall of the material box 11 through a notch, accurately positioning the material box 11 and initially limiting the material height; the second scraper 155 coarsely scrapes the material surface with its conical bottom wall, quickly leveling protruding materials; the third scraper 156 penetrates deeper into the box for fine scraping, further correcting the flatness of the material and avoiding material accumulation or depressions caused by a single leveling operation, ensuring consistent sampling volume. Furthermore, the spaced arrangement of the three scrapers disperses the reaction force of the material on the scrapers, preventing a single scraper from deforming due to concentrated load; the gaps between the scrapers provide buffer space for the material, allowing excess material to be smoothly discharged during the leveling process. A material sensor 16 is also installed in the sampling chamber 12, and the material sensor 16 is signal-connected to the control unit. The material sensor 16 is located above the door 14. A bracket is fixedly installed inside the sampling chamber 12. The material sensor 16 is fixedly installed on the bracket with bolts. Its function is to detect the amount of material entering the material box 11.

[0022] like Figure 4As shown, the transfer unit 3 includes a first guide rail 31, with two base blocks 32 fixed to the bottom of the first guide rail 31. The two base blocks 32 are respectively positioned near both ends of the first guide rail 31. One end of the first guide rail 31 is positioned opposite to the detection inlet 211 to ensure that the material box 11 can be accurately transferred to the sealing unit 4. A first slider 33 is slidably mounted on the first guide rail 31. Both ends of the first guide rail 31 are provided with stops 34, and limit switches 35 are respectively provided near both ends. A drive motor (not shown in the figure) is fixedly mounted on one of the stops 34. In this embodiment, the structure of the first guide rail 31 and the first slider 33 can adopt commercially available electric slides, such as the FBL60 series electric slides from Fuyu Technology or the PCB60 series electronic slides from Panyan Technology. The specific model of the product is not limited here, but is only an example. Its working principle is as follows: the drive motor rotates, which drives the synchronous pulley to rotate. The synchronous pulley, through the synchronous belt, converts the rotational motion into linear motion. The first slider 33 is fixed to the synchronous belt. The linear movement of the synchronous belt will cause the first slider 33 to reciprocate linearly along the first guide rail 31. The electric slide table is existing technology, and its specific structure will not be described in detail.

[0023] A rotating platform 36 is fixedly mounted on the top of the first slider 33, and an electric gripper 37 is fixedly mounted on the top of the rotating platform 36. The electric gripper 37 can stably hold the material box 11 and drive the material box 11 to rotate. The rotating platform 36 can adjust the angle of the material box 11 to rotate 180 degrees according to the transfer requirements. In conjunction with the sliding of the first slider 33 on the first slide rail, the material box 11 can be efficiently and accurately transferred from the sampling unit 1 to the sealing unit 4. Both the rotating platform 36 and the electric gripper 37 are commercially available products, and selection can be made according to requirements; further details are omitted here. The gripper part of the electric gripper 37 integrates a rotary motor, which can drive the material box 11 to achieve a 360-degree flip to complete the material box 11 flipping and discarding action.

[0024] It is important to note that the transfer unit 3 can also use a six-axis robotic arm. The six-axis robotic arm can fully perform the actions of sampling and discarding samples from the sampling chamber 12, and can complete the placement of samples into the detection inlet 211 of the vacuum detection chamber 21.

[0025] The detection unit 2 includes a vacuum detection chamber 21 and a full-element mineral composition analyzer 22. The vacuum detection chamber 21 is located below the full-element mineral composition analyzer 22, and its function is to provide a detection space that meets the detection requirements of the full-element mineral composition analyzer 22. The full-element mineral composition analyzer 22 is fixed to the top of the vacuum detection chamber 21 by bolts, and is used to detect the indicators or elemental composition of the material in the material box 11 inside the vacuum detection chamber 21. The specific requirements are determined according to the conditions of each site. For coal mines, the general indicators to be detected are ash content, moisture, sulfur content, calorific value, and volatile matter. In this embodiment, the full-element mineral composition analyzer 22 can be used in industries such as coal mines, iron mines, manganese mines, chromium mines, copper mines, lead-zinc mines, bauxite mines, tungsten mines, tin mines, molybdenum mines, nickel mines, antimony mines, gold mines, silver mines, and phosphate mines, as well as non-coal mines. The measured indicators and elements include: ash content, moisture, sulfur content, calorific value, volatile matter, ash melting point, SiO2, Al2O3, CaO, Fe2O3 in the ash, iron grade, alkalinity, calcium (Ca), magnesium (Mg), silicon (Si), and titanium (Ti). The instrument provides data on the content of various mineral elements, including zinc (Zn), aluminum (Al), sulfur (S), phosphorus (P), gold (Au), silver (Ag), arsenic (As), sulfur (S), copper (Cu), lead (Pb), mercury (Hg), cadmium (Cd), manganese (Mn), sodium (Na), potassium (K), barium (Ba), nickel (Ni), molybdenum (Mo), cobalt (Co), chromium (Cr), tin (Sn), tungsten (W), yttrium (Y), vanadium (V), niobium (Nb), tantalum (Ta), thorium (Th), and uranium (U). The principle of the all-element bypass mineral composition analyzer can be, but is not limited to, online X-ray reflection detection technology, online X-ray transmission detection technology, X-ray fluorescence analysis, laser-induced breakdown spectroscopy, near-infrared measurement technology, neutron activation transient gamma-ray detection technology, or any combination of the above technologies.

[0026] like Figure 5 and Figure 6As shown, it also includes a fixed frame 6, with a long mounting plate 61 on the top of the fixed frame 6. Second guide rails 62 are symmetrically arranged on both sides of the long mounting plate 61, and second sliders 63 are slidably mounted on the second guide rails 62. A vacuum detection chamber 21 is bolted to one end of the top of the long mounting plate 61, and a circular detection inlet 211 is opened on one side wall of the chamber. The detection probe of the full-element mineral composition analyzer 22 passes through the top of the vacuum detection chamber 21 and is sealed to the vacuum detection chamber 21. A vertical mounting plate 64 is bolted to the other end of the long mounting plate 61. A support frame 65 is fixedly connected to the vertical mounting plate 64. The support frame 65 has an L-shaped structure, and an electric push rod 66 is fixedly mounted on the support frame 65. The electric push rod 66 is located directly in front of the detection inlet 211 of the vacuum detection chamber 21, and its axis coincides with the axis of the detection inlet 211. The movable end of the electric push rod 66 is fixedly connected to a slide plate 67, and the slide plate 67 is fixedly connected to two second sliders 63 to ensure that the electric push rod 66 drives the slide plate 67 and the two second sliders 63 to slide stably along the second slide rail.

[0027] like Figure 7 As shown, the sealing unit 4 includes a sealing top core 41 and a dustproof plate 42. The sealing top core 41 and the dustproof plate 42 are fixedly connected by a bracket 43. The bracket 43 has a U-shaped structure, and a magnet 44 is fixedly installed in the middle of the bottom wall of the bracket 43. A magnetic absorbing piece (not shown in the figure) is correspondingly embedded in the bottom of the material box 11. The magnet 44 and the magnetic absorbing piece are magnetically attracted to each other, realizing the quick fixation of the material box 11. The sealing top core 41 is fixedly connected to the slide plate 67 and is located on the side of the slide plate 67 away from the electric push rod 66. The sealing top core 41 includes a first column 411. One end of the first column 411 is integrally formed with a stop plate 412, and the other end is a conical structure and is fixedly connected to one end of the bracket 43 by bolts. The outer diameter of the stop plate 412 is larger than the outer diameter of the first column 411. The outer wall of the first column 411 has several grooves along its axial direction, and sealing rings 413 are installed in the grooves. The sealing rings 413 are made of vacuum-resistant fluororubber, ensuring a reliable seal after the sealing core 41 is inserted into the detection inlet 211. The dustproof plate 42 includes a second column 421 and a third column 422 arranged coaxially, which are integrally formed. The diameter of the second column 421 is smaller than the diameter of the third column 422, and one end of the second column 421 is fixedly connected to the other end of the bracket 43 by bolts. The total length of the dustproof plate 42 is greater than the depth of the detection inlet 211. In the non-detection state, the third column 422 is inserted into the detection inlet 211 to achieve dust prevention.

[0028] A negative pressure pump 5 is connected to the outside of the vacuum testing chamber 21 via a pipeline. The negative pressure pump 5 is fixed to the fixed frame 6 with bolts, and its control end is connected to the control unit via a wire signal connection. A filter (not shown in the figure) is also installed on the pipeline, which is located next to the air inlet of the negative pressure pump 5. Its inlet end is directly connected to the air extraction port of the vacuum testing chamber 21 via a pipeline. A pressure regulating valve (not shown in the figure) is installed on the side of the pipeline between the filter and the negative pressure pump 5. A solenoid valve (not shown in the figure) is installed in series in the air outlet pipeline of the negative pressure pump 5. A pressure sensor (not shown in the figure) is installed in the pipeline between the pressure regulating valve and the negative pressure pump 5 using a clamp. The negative pressure pump 5, filter, pressure regulating valve, solenoid valve, and pressure sensor are all installed on the fixed frame 6. The pressure regulating valve can adjust the extracted pressure value, the pressure sensor detects the pressure value extracted by the pump, the solenoid valve controls the flow path of the fluid and can switch between the working port and the exhaust port, and the filter filters out dust and particles in the air extracted from the testing chamber.

[0029] It also includes a host computer (not shown in the figure), which is electrically connected to the full-element mineral composition analyzer 22. The data from the full-element mineral composition analyzer 22 during the detection process can be displayed and output on the host computer in real time. The PLC controllers used in the host computer and control unit are existing technologies and are not the object of protection of this invention. The connection structure between the various electrical components is also a conventional setting for those skilled in the art, and will not be described in detail here.

[0030] The working process of the all-element bypass mineral composition analyzer of the present invention is as follows: The control unit drives the door 14 of the sampling chamber 12 to open outward to the maximum angle through the electric push rod 66, servo motor or pulley mechanism according to the preset program, to ensure that the material box 11 can enter and exit smoothly; the drive motor of the transfer unit 3 starts, and drives the first slider 33 to move along the first guide rail 31 towards the sampling chamber 12 through the synchronous pulley and synchronous belt transmission, which drives the electric gripper 37 to clamp the empty material box 11 close to the door 14 and enter the sampling chamber 12 directly below the feed inlet 121. The material to be tested falls into the material box 11 in the sampling chamber 12 through the feed inlet 121. During sampling, some spilled material is discharged into the sample collector 13 through the discharge port 122. The material detection sensor detects the thickness of the material in the material box 11 in real time. When the set value is reached, a signal is sent to the control unit. After receiving the full material signal, the control unit uses the electric gripper 37 to hold the material box 11 and move it backward along the first slide rail. When the material box 11 passes the scraper device, the three scrapers scrape and shape the material inside. After the material box 11 is removed from the sampling chamber 12, the rotating platform 36 drives the electric gripper 37 to rotate 180 degrees to complete the direction adjustment. Then, the electric gripper 37 holds the material box 11 and continues to move it along the first slide rail. When the material box 11 reaches the vacuum detection... When the material box 11 is directly above the bracket 43 at the detection inlet 211 of chamber 21, the process stops. The electric gripper 37 releases the material box 11, which is then placed on the bracket 43. The magnet 44 on the bracket 43 magnetically attracts the magnetic plate at the bottom of the material box 11, and the electric gripper 37 releases the material box 11. The control unit then starts the electric push rod 66, driving the slide plate 67 and the second slider 63 to slide along the second slide rail toward the vacuum detection chamber 21. This causes the sealing top core 41 and the bracket 43 containing the material box 11 to move synchronously. The sealing top core 41 is inserted into the detection inlet 211, and the sealing ring 413 is flush with the inner wall of the detection inlet 211. The baffle 412 fits tightly against the outer wall of the vacuum detection chamber 21, achieving a seal. Subsequently, the control unit controls the negative pressure pump 5 to start, drawing air from the vacuum detection chamber 21. As the air passes through the pipeline, the filter removes impurities and dust. The pressure sensor detects the pressure value inside the vacuum detection chamber 21 in real time. When the pressure reaches the preset value, the pressure sensor sends a signal to the control unit, which then controls the negative pressure pump 5 to stop working. The detection probe of the all-element mineral composition analyzer 22 detects the mineral composition in the material box 11. The detection data is transmitted to the control unit in real time, processed, stored, and displayed on the host computer.After the test is completed, the control unit stops the negative pressure pump 5, and the electric push rod 66 drives the slide plate 67 to slide in the opposite direction, causing the sealing unit 4 and the material box 11 to exit the vacuum testing chamber 21. The dustproof plate 42 is reset and inserted into the testing inlet 211. The electric gripper 37 of the transfer unit 3 clamps the material box 11 and transfers it to the sampling chamber 12. The electric gripper 37 clamps the material box 11 and begins to rotate. During the rotation, the material is discharged through the discharge port 122. The electric gripper 37 rotates the material box 11 360 degrees and continues to wait to receive the next material to be tested, completing one testing cycle.
