Description

Technical Field

[0001] This invention relates to the field of petroleum geology technology, and in particular to an experimental apparatus, experimental method and detection system for X-ray diffraction of clay. Background Technology

[0002] X-ray diffraction (XRD) analysis of clay minerals is widely used in petroleum geological research. XRD clay analysis mainly involves qualitative and quantitative analysis of minerals such as illite-montmorillonite mixed layers, chlorite-montmorillonite mixed layers, kaolinite, chlorite, and illite. Among these, clay mineral pretreatment is an important step.

[0003] The pretreatment of clay minerals includes saturating clay sheets with ethylene glycol vapor by fumigation, which causes montmorillonite and kaolinite to expand and shift, thereby distinguishing the mixed-layer, illite, and other mineral components. It also includes high-temperature burning of the saturated clay sheets, which causes chlorite to burn away and kaolinite to transform into illite, thereby differentiating the various components.

[0004] In the pretreatment of clay minerals, clay sheets are usually placed using wooden or iron grid supports as auxiliary devices. However, the existing auxiliary devices cannot be adjusted, which means that the angle of the clay sheets cannot be adjusted during ethylene glycol saturation fumigation and high-temperature burning. This not only prolongs the pretreatment time but also causes uneven saturation fumigation and high-temperature burning. Summary of the Invention

[0005] This invention provides an experimental apparatus, method, and detection system for X-ray diffraction of clay, which can solve the problem that existing auxiliary devices cannot adjust the angle of clay sheets during ethylene glycol saturation fumigation and high-temperature calcination.

[0006] In a first aspect, embodiments of the present invention provide an experimental apparatus for X-ray diffraction of clay, comprising:

[0007] Support frame;

[0008] A support assembly, rotatably disposed within the support frame, and the support assembly being used to secure the clay sheet; and

[0009] A baffle assembly is disposed within the support frame and is located below the support assembly. The baffle assembly is used to catch clay fragments falling from the support assembly.

[0010] In one embodiment, the support component includes:

[0011] A support shaft passes through the support frame, and the support shaft is rotatably connected to the support frame;

[0012] An adjustment handle is located at one end of the support shaft;

[0013] A fixing seat is provided at the end of the support shaft away from the adjusting handle; and

[0014] A support frame is disposed on the support shaft.

[0015] In one embodiment, the support frame includes:

[0016] A template is provided on the supporting shaft;

[0017] A first limiting plate is disposed on one side of the support plate, and the first limiting plate extends along the width direction;

[0018] A second limiting plate is movably disposed on the support plate, and the second limiting plate extends along the width direction; and

[0019] The second limiting plate is movable along the length direction to adjust the distance between the second limiting plate and the first limiting plate in the length direction.

[0020] In one embodiment, the two ends of the sample plate are provided with through grooves, and the two ends of the second limiting plate are provided with threaded holes. The threaded holes correspond one-to-one with the through grooves, and the threaded holes are connected to the corresponding through grooves.

[0021] The experimental apparatus further includes fasteners that are connected to the threaded hole and the through groove, so as to connect the second limiting plate to the sample plate.

[0022] In one embodiment, the baffle assembly includes:

[0023] A plurality of first baffles, the plurality of first baffles being arranged at equal intervals along the length direction, and the first baffles extending along the width direction; and

[0024] A plurality of second baffles are arranged at equal intervals along the length direction, the second baffles extend along the width direction, the second baffles are located above the first baffles, and the second baffles and the first baffles are spaced apart in the height direction;

[0025] In this arrangement, a plurality of first baffles and a plurality of second baffles are staggered along the length direction, and the first baffles are connected to adjacent second baffles. On a plane perpendicular to the height direction, the projection of the first baffle overlaps with the projection of the adjacent second baffle.

[0026] In one embodiment, the cross-sections of the first baffle and the second baffle are both arc-shaped, and the inner arc surfaces of the first baffle and the second baffle both face the supporting component.

[0027] In one embodiment, the first limiting plate includes:

[0028] A fixed section, one end of which is connected to the support plate, extends along the height direction; and

[0029] The limiting segment is connected to the end of the fixed segment away from the bearing plate, and the limiting segment extends along the length direction.

[0030] Secondly, embodiments of the present invention provide an experimental method applied to the experimental apparatus described above, comprising:

[0031] The clay sheet is placed on the support assembly and fixed by the first limiting plate and the second limiting plate of the support assembly;

[0032] The experimental apparatus containing the clay sheet was placed in a desiccator containing ethylene glycol, and the clay sheet was fumigated by the desiccator.

[0033] After a preset time, the clay sheet, which has been fumigated to saturation, and the experimental apparatus are placed in the muffle furnace, and the clay sheet is burned in the muffle furnace.

[0034] In one embodiment, fumigating the clay sheets using the dryer includes:

[0035] The fumigation temperature is 50℃-60℃.

[0036] Thirdly, embodiments of the present invention provide a detection system, including the experimental apparatus as described above.

[0037] Compared with existing technologies, the advantages of this invention are as follows: by setting a support component to fix the clay sheet, the clay sheet is prevented from falling off during pretreatment, thus avoiding the need for users to re-prepare samples and reducing clay testing efficiency. The support component rotates the clay sheet, adjusting its angle so that the angle can be adjusted as needed during saturated fumigation and high-temperature burning, ensuring that all parts of the clay sheet are fully fumigated and burned, guaranteeing uniform fumigation and burning, thereby shortening pretreatment time and improving the efficiency of clay analysis and testing. Furthermore, by setting a baffle component below the support component, clay fragments and dust are prevented from falling into the ethylene glycol solution during fumigation, which could easily contaminate the ethylene glycol.

[0047] The invention will now be further described with reference to the accompanying drawings.

[0048] The pretreatment of clay minerals includes saturating clay sheets with ethylene glycol vapor by fumigation, which causes montmorillonite and kaolinite to expand and shift, thereby distinguishing the mixed-layer, illite, and other mineral components. It also includes high-temperature burning of the saturated clay sheets, which causes chlorite to burn away and kaolinite to transform into illite, thereby differentiating the various components.

[0049] In the pretreatment of clay minerals, clay sheets are usually placed using wooden or iron grid supports as auxiliary devices. However, the existing auxiliary devices cannot be adjusted, which means that the angle of the clay sheets cannot be adjusted during ethylene glycol saturation fumigation and high-temperature burning. This not only prolongs the pretreatment time but also causes uneven saturation fumigation and high-temperature burning.

[0050] Example 1

[0051] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides an experimental apparatus for X-ray diffraction of clay, including a support frame 10, a support component 20, and a baffle assembly 30; the support component 20 is rotatably disposed within the support frame 10 and is used to fix clay sheets; the baffle assembly 30 is disposed within the support frame 10, located below the support component 20, and is used to collect clay sheet fragments falling from the support component 20.

[0052] As can be seen from the above, by setting up the support component 20 to fix the clay sheet, it is possible to prevent the clay sheet from falling off during the pretreatment process, which would require the user to re-prepare the sample and reduce the efficiency of clay testing. The support component 20 drives the clay sheet to rotate, thereby adjusting the angle of the clay sheet. This allows the clay sheet to be adjusted as needed during saturated fumigation and high-temperature burning, ensuring that all parts of the clay sheet are fully fumigated and burned, thus guaranteeing uniform fumigation and burning, shortening the pretreatment time and improving the efficiency of clay analysis and testing. By setting up the baffle component 30 below the support component 20, it is possible to prevent clay fragments and dust from falling into the ethylene glycol solution during fumigation, which could easily contaminate the ethylene glycol.

[0053] It should be noted that the support frame 10, the supporting component 20, and the baffle assembly 30 are all made of metal; the support frame 10 has a cubic structure, and a supporting cavity is provided inside the support frame 10 that runs through the support frame 10 in the height direction. The supporting component 20 and the baffle assembly 30 are both located inside the supporting cavity.

[0054] It should also be noted that, such as Figure 1 , Figure 2 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

[0055] It should also be noted that the number of support components 20 is set according to needs. The more support components 20 there are, the more clay sheets can be supported and fixed, allowing for simultaneous pretreatment of multiple clay sheets and improving clay testing efficiency. However, the number of support components 20 should not be excessive, as this would increase the manufacturing cost of the experimental apparatus. For example, ... Figure 1 As shown, the number of supporting components 20 is 7.

[0056] Example 2

[0057] like Figure 1 , Figure 2 As shown, the experimental apparatus for X-ray diffraction of clay includes a support frame 10, a support assembly 20, and a baffle assembly 30; the support assembly 20 is rotatably disposed within the support frame 10 and is used to fix the clay sheet; the baffle assembly 30 is disposed within the support frame 10, located below the support assembly 20, and is used to collect clay sheet fragments falling from the support assembly 20.

[0058] As can be seen from the above, by setting up the support component 20 to fix the clay sheet, it is possible to prevent the clay sheet from falling off during the pretreatment process, which would require the user to re-prepare the sample and reduce the efficiency of clay testing. The support component 20 drives the clay sheet to rotate, thereby adjusting the angle of the clay sheet. This allows the clay sheet to be adjusted as needed during saturated fumigation and high-temperature burning, ensuring that all parts of the clay sheet are fully fumigated and burned, thus guaranteeing uniform fumigation and burning, shortening the pretreatment time and improving the efficiency of clay analysis and testing. By setting up the baffle component 30 below the support component 20, it is possible to prevent clay fragments and dust from falling into the ethylene glycol solution during fumigation, which could easily contaminate the ethylene glycol.

[0059] It should be noted that the support frame 10, the supporting component 20, and the baffle assembly 30 are all made of metal; the support frame 10 has a cubic structure, and a supporting cavity is provided inside the support frame 10 that runs through the support frame 10 in the height direction. The supporting component 20 and the baffle assembly 30 are both located inside the supporting cavity.

[0060] It should also be noted that, such as Figure 1 , Figure 2 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

[0061] It should also be noted that the number of support components 20 is set according to needs. The more support components 20 there are, the more clay sheets can be supported and fixed, allowing for simultaneous pretreatment of multiple clay sheets and improving clay testing efficiency. However, the number of support components 20 should not be excessive, as this would increase the manufacturing cost of the experimental apparatus. For example, ... Figure 1 As shown, the number of supporting components 20 is 7.

[0062] like Figure 1 , Figure 2 As shown, in some embodiments, the support assembly 20 includes a support shaft 210, an adjustment handle 220, a fixing seat 230, and a support frame 240; the support shaft 210 passes through the support frame 10 and is rotatably connected to the support frame 10; the adjustment handle 220 is disposed at one end of the support shaft 210; the fixing seat 230 is disposed at the end of the support shaft 210 away from the adjustment handle 220; and the support frame 240 is disposed on the support shaft 210.

[0063] By setting up a support frame 240 to support and fix the clay sheet, rotating the adjustment handle 220 drives the support shaft 210 to rotate, and the support frame 240 rotates with the support shaft 210, thereby adjusting the angle of the clay sheet; the support shaft 210 is fixed by a fixing seat 230 that is threadedly connected to the support shaft 210. When it is necessary to adjust the angle of the clay sheet, rotate the fixing seat 230 to move the fixing seat 230 away from the support frame 10, and rotate the adjustment handle 220 to adjust the angle of the clay sheet. When it is not necessary to adjust the angle of the clay sheet, rotate the fixing seat 230 to make the fixing seat 230 abut against the support frame 10 to fix the support shaft 210, thus making the adjustment method simple and convenient.

[0064] It should be noted that the fixing seat 230 includes, but is not limited to, a nut; the support frame 10 is provided with a support hole for the support shaft 210 to pass through.

[0065] Example 3

[0066] like Figure 1 , Figure 2 As shown, the experimental apparatus for X-ray diffraction of clay includes a support frame 10, a support assembly 20, and a baffle assembly 30; the support assembly 20 is rotatably disposed within the support frame 10 and is used to fix the clay sheet; the baffle assembly 30 is disposed within the support frame 10, located below the support assembly 20, and is used to collect clay sheet fragments falling from the support assembly 20.

[0067] As can be seen from the above, by setting up the support component 20 to fix the clay sheet, it is possible to prevent the clay sheet from falling off during the pretreatment process, which would require the user to re-prepare the sample and reduce the efficiency of clay testing. The support component 20 drives the clay sheet to rotate, thereby adjusting the angle of the clay sheet. This allows the clay sheet to be adjusted as needed during saturated fumigation and high-temperature burning, ensuring that all parts of the clay sheet are fully fumigated and burned, thus guaranteeing uniform fumigation and burning, shortening the pretreatment time and improving the efficiency of clay analysis and testing. By setting up the baffle component 30 below the support component 20, it is possible to prevent clay fragments and dust from falling into the ethylene glycol solution during fumigation, which could easily contaminate the ethylene glycol.

[0068] It should be noted that the support frame 10, the supporting component 20, and the baffle assembly 30 are all made of metal; the support frame 10 has a cubic structure, and a supporting cavity is provided inside the support frame 10 that runs through the support frame 10 in the height direction. The supporting component 20 and the baffle assembly 30 are both located inside the supporting cavity.

[0069] It should also be noted that, such as Figure 1 , Figure 2 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

[0070] It should also be noted that the number of support components 20 is set according to needs. The more support components 20 there are, the more clay sheets can be supported and fixed, allowing for simultaneous pretreatment of multiple clay sheets and improving clay testing efficiency. However, the number of support components 20 should not be excessive, as this would increase the manufacturing cost of the experimental apparatus. For example, ... Figure 1 As shown, the number of supporting components 20 is 7.

[0071] like Figure 1 , Figure 2 As shown, in some embodiments, the support assembly 20 includes a support shaft 210, an adjustment handle 220, a fixing seat 230, and a support frame 240; the support shaft 210 passes through the support frame 10 and is rotatably connected to the support frame 10; the adjustment handle 220 is disposed at one end of the support shaft 210; the fixing seat 230 is disposed at the end of the support shaft 210 away from the adjustment handle 220; and the support frame 240 is disposed on the support shaft 210.

[0072] By setting up a support frame 240 to support and fix the clay sheet, rotating the adjustment handle 220 drives the support shaft 210 to rotate, and the support frame 240 rotates with the support shaft 210, thereby adjusting the angle of the clay sheet; the support shaft 210 is fixed by a fixing seat 230 that is threadedly connected to the support shaft 210. When it is necessary to adjust the angle of the clay sheet, rotate the fixing seat 230 to move the fixing seat 230 away from the support frame 10, and rotate the adjustment handle 220 to adjust the angle of the clay sheet. When it is not necessary to adjust the angle of the clay sheet, rotate the fixing seat 230 to make the fixing seat 230 abut against the support frame 10 to fix the support shaft 210, thus making the adjustment method simple and convenient.

[0073] It should be noted that the fixing seat 230 includes, but is not limited to, a nut; the support frame 10 is provided with a support hole for the support shaft 210 to pass through.

[0074] like Figure 1 , Figure 2 As shown, in some embodiments, the support frame 240 includes a support template 2401, a first limiting plate 2402, and a second limiting plate 2403; the support template 2401 is disposed on the support shaft 210; the first limiting plate 2402 is disposed on one side of the support template 2401 and extends along the width direction; the second limiting plate 2403 is movably disposed on the support template 2401 and extends along the width direction; wherein, the second limiting plate 2403 can move along the length direction to adjust the distance between the second limiting plate 2403 and the first limiting plate 2402 in the length direction.

[0075] By setting up a support plate 2401, a first limiting plate 2402 and a second limiting plate 2403 to fix the clay sheet together, the clay sheet is prevented from falling off. The second limiting plate 2403 can move along the length direction to clamp clay sheets of different sizes, thereby greatly improving practicality and flexibility.

[0076] It should be noted that the clay sheet dimensions are 15mm x 15mm x 2mm, or 30mm x 30mm x 2.5mm.

[0077] It should also be noted that when the clay sheet is placed on the support plate 2401, the first limiting plate 2402 abuts against one end of the clay sheet, and then the second limiting plate 2403 is moved so that the second limiting plate 2403 presses down on the end of the clay sheet away from the first limiting plate 2402. The second limiting plate 2403 presses down on the clay sheet for 2mm-3mm in the length direction, thereby fixing the clay sheet.

[0078] like Figure 1 , Figure 2 As shown, in some embodiments, the two ends of the sample plate 2401 are provided with through grooves 2404, and the two ends of the second limiting plate 2403 are provided with threaded holes, the threaded holes and the through grooves 2404 are corresponding one-to-one, and the threaded holes are connected to the corresponding through grooves 2404; wherein, the experimental device also includes fasteners 2405, the fasteners 2405 are connected to the threaded holes and through grooves 2404, so that the second limiting plate 2403 is connected to the sample plate 2401.

[0079] The through groove 2404 and threaded hole provide a structural basis for the movement and fixation of the second limiting plate 2403. The fixing and loosening of the second limiting plate 2403 are achieved by rotating the fastener 2405. The method is simple and convenient. When it is necessary to change the distance between the first limiting plate 2402 and the second limiting plate 2403, rotate the fastener 2405 to loosen the second limiting plate 2403 from the support plate 2401, and drive the second limiting plate 2403 to move, so as to change the distance between the second limiting plate 2403 and the first limiting plate 2402. When the distance between the first limiting plate 2402 and the second limiting plate 2403 is adjusted, rotate the fastener 2405 to connect the second limiting plate 2403 to the support plate 2401.

[0080] It should be noted that the fastener 2405 can be a bolt or a nut. By tightening or loosening the nut, the second limiting plate 2403 can be fixed or loosened, respectively.

[0081] It should also be noted that the through groove 2404 penetrates through the bearing plate 2401 in the height direction, and the distance between the two ends of the through groove 2404 and the edge of the second limiting plate 2403 is equal, both being 3mm-5mm.

The plurality of first baffles 310 and the plurality of second baffles 320 are staggered in the length direction. The first baffles 310 are connected to adjacent second baffles 320. On a plane perpendicular to the height direction, the projection of the first baffle 310 overlaps with the projection of the adjacent second baffle 320.

[0100] By setting overlapping first baffles 310 and second baffles 320, fragments or dust of clay sheets are effectively prevented from falling downwards. At the same time, the first baffles 310 and second baffles 320 have a gap in the height direction, which can ensure that ethylene glycol vapor passes upwards during fumigation and avoid affecting the saturation efficiency of ethylene glycol fumigation.

[0101] It should be noted that the length of the overlapping area between the first baffle 310 and the adjacent second baffle 320 is 5mm; the height of the first baffle 310 and the second baffle 320 is specifically set according to the height of the support frame 10 and the supporting component 20, for example, the height of the first baffle 310 and the second baffle 320 is 1.5mm.

[0102] It should also be noted that the distance between the first baffle 310 and the second baffle 320 in the height direction is 5mm.

[0103] Example 5

[0104] like Figure 1 , Figure 2 As shown, the experimental apparatus for X-ray diffraction of clay includes a support frame 10, a support assembly 20, and a baffle assembly 30; the support assembly 20 is rotatably disposed within the support frame 10 and is used to fix the clay sheet; the baffle assembly 30 is disposed within the support frame 10, located below the support assembly 20, and is used to collect clay sheet fragments falling from the support assembly 20.

[0105] As can be seen from the above, by setting up the support component 20 to fix the clay sheet, it is possible to prevent the clay sheet from falling off during the pretreatment process, which would require the user to re-prepare the sample and reduce the efficiency of clay testing. The support component 20 drives the clay sheet to rotate, thereby adjusting the angle of the clay sheet. This allows the clay sheet to be adjusted as needed during saturated fumigation and high-temperature burning, ensuring that all parts of the clay sheet are fully fumigated and burned, thus guaranteeing uniform fumigation and burning, shortening the pretreatment time and improving the efficiency of clay analysis and testing. By setting up the baffle component 30 below the support component 20, it is possible to prevent clay fragments and dust from falling into the ethylene glycol solution during fumigation, which could easily contaminate the ethylene glycol.

[0106] It should be noted that the support frame 10, the supporting component 20, and the baffle assembly 30 are all made of metal; the support frame 10 has a cubic structure, and a supporting cavity is provided inside the support frame 10 that runs through the support frame 10 in the height direction. The supporting component 20 and the baffle assembly 30 are both located inside the supporting cavity.

[0107] It should also be noted that, such as Figure 1 , Figure 2 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

[0108] It should also be noted that the number of support components 20 is set according to needs. The more support components 20 there are, the more clay sheets can be supported and fixed, allowing for simultaneous pretreatment of multiple clay sheets and improving clay testing efficiency. However, the number of support components 20 should not be excessive, as this would increase the manufacturing cost of the experimental apparatus. For example, ... Figure 1 As shown, the number of supporting components 20 is 7.

[0109] like Figure 1 , Figure 2 As shown, in some embodiments, the support assembly 20 includes a support shaft 210, an adjustment handle 220, a fixing seat 230, and a support frame 240; the support shaft 210 passes through the support frame 10 and is rotatably connected to the support frame 10; the adjustment handle 220 is disposed at one end of the support shaft 210; the fixing seat 230 is disposed at the end of the support shaft 210 away from the adjustment handle 220; and the support frame 240 is disposed on the support shaft 210.

[0110] By setting up a support frame 240 to support and fix the clay sheet, rotating the adjustment handle 220 drives the support shaft 210 to rotate, and the support frame 240 rotates with the support shaft 210, thereby adjusting the angle of the clay sheet; the support shaft 210 is fixed by a fixing seat 230 that is threadedly connected to the support shaft 210. When it is necessary to adjust the angle of the clay sheet, rotate the fixing seat 230 to move the fixing seat 230 away from the support frame 10, and rotate the adjustment handle 220 to adjust the angle of the clay sheet. When it is not necessary to adjust the angle of the clay sheet, rotate the fixing seat 230 to make the fixing seat 230 abut against the support frame 10 to fix the support shaft 210, thus making the adjustment method simple and convenient.

[0111] It should be noted that the fixing seat 230 includes, but is not limited to, a nut; the support frame 10 is provided with a support hole for the support shaft 210 to pass through.

[0112] like Figure 1 , Figure 2 As shown, in some embodiments, the support frame 240 includes a support template 2401, a first limiting plate 2402, and a second limiting plate 2403; the support template 2401 is disposed on the support shaft 210; the first limiting plate 2402 is disposed on one side of the support template 2401 and extends along the width direction; the second limiting plate 2403 is movably disposed on the support template 2401 and extends along the width direction; wherein, the second limiting plate 2403 can move along the length direction to adjust the distance between the second limiting plate 2403 and the first limiting plate 2402 in the length direction.

[0113] By setting up a support plate 2401, a first limiting plate 2402 and a second limiting plate 2403 to fix the clay sheet together, the clay sheet is prevented from falling off. The second limiting plate 2403 can move along the length direction to clamp clay sheets of different sizes, thereby greatly improving practicality and flexibility.

[0114] It should be noted that the clay sheet dimensions are 15mm x 15mm x 2mm, or 30mm x 30mm x 2.5mm.

[0115] It should also be noted that when the clay sheet is placed on the support plate 2401, the first limiting plate 2402 abuts against one end of the clay sheet, and then the second limiting plate 2403 is moved so that the second limiting plate 2403 presses down on the end of the clay sheet away from the first limiting plate 2402. The second limiting plate 2403 presses down on the clay sheet for 2mm-3mm in the length direction, thereby fixing the clay sheet.

[0116] like Figure 1 , Figure 2As shown, in some embodiments, the two ends of the sample plate 2401 are provided with through grooves 2404, and the two ends of the second limiting plate 2403 are provided with threaded holes, the threaded holes and the through grooves 2404 are corresponding one-to-one, and the threaded holes are connected to the corresponding through grooves 2404; wherein, the experimental device also includes fasteners 2405, the fasteners 2405 are connected to the threaded holes and through grooves 2404, so that the second limiting plate 2403 is connected to the sample plate 2401.

[0117] The through groove 2404 and threaded hole provide a structural basis for the movement and fixation of the second limiting plate 2403. The fixing and loosening of the second limiting plate 2403 are achieved by rotating the fastener 2405. The method is simple and convenient. When it is necessary to change the distance between the first limiting plate 2402 and the second limiting plate 2403, rotate the fastener 2405 to loosen the second limiting plate 2403 from the support plate 2401, and drive the second limiting plate 2403 to move, so as to change the distance between the second limiting plate 2403 and the first limiting plate 2402. When the distance between the first limiting plate 2402 and the second limiting plate 2403 is adjusted, rotate the fastener 2405 to connect the second limiting plate 2403 to the support plate 2401.

[0118] It should be noted that the fastener 2405 can be a bolt or a nut. By tightening or loosening the nut, the second limiting plate 2403 can be fixed or loosened, respectively.

[0119] It should also be noted that the through groove 2404 penetrates through the support plate 2401 in the height direction, and the distance between the two ends of the through groove 2404 and the edge of the second limiting plate 2403 is equal, both being 3mm-5mm.

[0120] like Figure 1 , Figure 2 As shown, in some embodiments, the baffle assembly 30 includes a plurality of first baffles 310 and a plurality of second baffles 320. The plurality of first baffles 310 are arranged at equal intervals along the length direction and extend along the width direction. The plurality of second baffles 320 are arranged at equal intervals along the length direction and extend along the width direction. The second baffles 320 are located above the first baffles 310 and have a distance between them and the first baffles 310 in the height direction. The plurality of first baffles 310 and the plurality of second baffles 320 are staggered in the length direction. The first baffles 310 are connected to adjacent second baffles 320. On a plane perpendicular to the height direction, the projection of the first baffle 310 overlaps with the projection of the adjacent second baffle 320.

[0121] By setting overlapping first baffles 310 and second baffles 320, fragments or dust of clay sheets are effectively prevented from falling downwards. At the same time, the first baffles 310 and second baffles 320 have a gap in the height direction, which can ensure that ethylene glycol vapor passes upwards during fumigation and avoid affecting the saturation efficiency of ethylene glycol fumigation.

[0122] It should be noted that the length of the overlapping area between the first baffle 310 and the adjacent second baffle 320 is 5mm; the height of the first baffle 310 and the second baffle 320 is specifically set according to the height of the support frame 10 and the supporting component 20, for example, the height of the first baffle 310 and the second baffle 320 is 1.5mm.

[0123] It should also be noted that the distance between the first baffle 310 and the second baffle 320 in the height direction is 5mm.

[0124] like Figure 1 , Figure 2 As shown, in one embodiment, the cross-sections of the first baffle 310 and the second baffle 320 are both arc-shaped, and the inner arc surfaces of the first baffle 310 and the second baffle 320 both face the supporting component 20.

[0125] By setting the first baffle 310 and the second baffle 320 in an arc shape, it is possible to further prevent clay fragments or dust from falling downwards.

[0126] It should be noted that the cross-section is a plane perpendicular to the width direction, and the radii of the arc surfaces of the first baffle 310 and the second baffle 320 are equal and the corresponding central angles are equal.

[0127] Example 6

[0128] like Figure 1 , Figure 2 As shown, the experimental apparatus for X-ray diffraction of clay includes a support frame 10, a support assembly 20, and a baffle assembly 30; the support assembly 20 is rotatably disposed within the support frame 10 and is used to fix the clay sheet; the baffle assembly 30 is disposed within the support frame 10, located below the support assembly 20, and is used to collect clay sheet fragments falling from the support assembly 20.

[0132] It should also be noted that the number of support components 20 is set according to needs. The more support components 20 there are, the more clay sheets can be supported and fixed, allowing for simultaneous pretreatment of multiple clay sheets and improving clay testing efficiency.

[0175] The through groove 2404 and threaded hole provide a structural basis for the movement and fixation of the second limiting plate 2403. The fixing and loosening of the second limiting plate 2403 are achieved by rotating the fastener 2405. The method is simple and convenient. When it is necessary to change the distance between the first limiting plate 2402 and the second limiting plate 2403, rotate the fastener 2405 to loosen the second limiting plate 2403 from the support plate 2401, and drive the second limiting plate 2403 to move, so as to change the distance between the second limiting plate 2403 and the first limiting plate 2402. When the distance between the first limiting plate 2402 and the second limiting plate 2403 is adjusted, rotate the fastener 2405 to connect the second limiting plate 2403 to the support plate 2401.

[0176] It should be noted that the fastener 2405 can be a bolt or a nut. By tightening or loosening the nut, the second limiting plate 2403 can be fixed or loosened, respectively.

[0177] It should also be noted that the through groove 2404 penetrates through the support plate 2401 in the height direction, and the distance between the two ends of the through groove 2404 and the edge of the second limiting plate 2403 is equal, both being 3mm-5mm.

[0178] like Figure 1 , Figure 2 As shown, in some embodiments, the baffle assembly 30 includes a plurality of first baffles 310 and a plurality of second baffles 320. The plurality of first baffles 310 are arranged at equal intervals along the length direction and extend along the width direction. The plurality of second baffles 320 are arranged at equal intervals along the length direction and extend along the width direction. The second baffles 320 are located above the first baffles 310 and have a distance between them and the first baffles 310 in the height direction. The plurality of first baffles 310 and the plurality of second baffles 320 are staggered in the length direction. The first baffles 310 are connected to adjacent second baffles 320. On a plane perpendicular to the height direction, the projection of the first baffle 310 overlaps with the projection of the adjacent second baffle 320.

[0179] By setting overlapping first baffles 310 and second baffles 320, fragments or dust of clay sheets are effectively prevented from falling downwards. At the same time, the first baffles 310 and second baffles 320 have a gap in the height direction, which can ensure that ethylene glycol vapor passes upwards during fumigation and avoid affecting the saturation efficiency of ethylene glycol fumigation.

[0180] It should be noted that the length of the overlapping area between the first baffle 310 and the adjacent second baffle 320 is 5mm; the height of the first baffle 310 and the second baffle 320 is specifically set according to the height of the support frame 10 and the supporting component 20, for example, the height of the first baffle 310 and the second baffle 320 is 1.5mm.

[0181] It should also be noted that the distance between the first baffle 310 and the second baffle 320 in the height direction is 5mm.

[0182] like Figure 1 , Figure 2 As shown, in one embodiment, the cross-sections of the first baffle 310 and the second baffle 320 are both arc-shaped, and the inner arc surfaces of the first baffle 310 and the second baffle 320 both face the supporting component 20.

[0183] By setting the first baffle 310 and the second baffle 320 in an arc shape, it is possible to further prevent clay fragments or dust from falling downwards.

[0184] It should be noted that the cross-section is a plane perpendicular to the width direction, and the radii of the arc surfaces of the first baffle 310 and the second baffle 320 are equal and the corresponding central angles are equal.

[0185] like Figure 1 , Figure 2 As shown, in some embodiments, the first limiting plate 2402 includes a fixing segment 2406 and a limiting segment 2407; one end of the fixing segment 2406 is connected to the support plate 2401, and the fixing segment 2406 extends along the height direction; the limiting segment 2407 is connected to the end of the fixing segment 2406 away from the support plate 2401, and the limiting segment 2407 extends along the length direction.

[0186] By setting the fixed section 2406 and the limiting section 2407, the clay sheet is limited in multiple directions, effectively preventing the clay sheet from slipping.

[0187] Example 8

[0188] In this embodiment, the clay sheet size is 15mm×15mm×2mm, and the clay film covers the 15mm×15mm plane. During the test, it is necessary to ensure that the clay film in the central 5mm×5mm area is intact.

[0189] After the clay sheets were prepared, the first test was performed using X-ray scanning. Subsequently, ethylene glycol sheets were prepared, such as... Figure 1 As shown, loosen the fastener 2405 to ensure that the second limiting plate 2403 can move freely. Place the clay sheet with the clay film covering it facing upwards on the support plate 2401, with the first limiting plate 2402 abutting against one end of the clay sheet. Then move the second limiting plate 2403 so that it presses down on the end of the clay sheet away from the first limiting plate 2402. The second limiting plate 2403 presses down on the clay sheet for 2mm-3mm along its length, thus fixing the clay sheet. This process requires ensuring that the clay film in the central 5mm × 5mm area is not obstructed and remains intact. Figure 2As shown, loosen the fastener 2405 and adjust the angle of the sample plate 2401 with the adjusting handle 220. For samples that are difficult to be saturated by ethylene glycol vapor, the adjusting handle 220 can be rotated to make the clay film in the fixed clay sheet face slightly downward so that it can be directly fumigated by the ethylene glycol vapor evaporating below, thereby improving the saturation effect.

[0190] After the above adjustments were completed, the entire experimental setup was placed in a desiccator containing ethylene glycol, sealed, and fumigated at 50℃-60℃ for 8 hours. Subsequently, ethylene glycol slide testing and X-ray diffraction analysis were performed. Compared with the first test results, the peak positions of montmorillonite, illite / montmorillonite interlayer minerals, and chlorophyllite / montmorillonite interlayer minerals changed.

[0191] After testing the clay slices saturated with ethylene glycol, the clay slices were subjected to high-temperature calcination. The clay slices were placed in the experimental apparatus using the same method as before ethylene glycol saturation, except that the angle of the clay slices could not be adjusted to a tilted position; instead, they should be adjusted to a horizontal position with the clay film facing upwards to prevent the clay film from slipping off during high-temperature calcination. The experimental apparatus, along with the clay slices, was placed in a muffle furnace and calcined at 450℃-550℃ for 3 hours. After cooling, the third test was conducted for X-ray diffraction analysis. Compared with the results of the first two tests, for kaolinite, the corresponding peak disappeared in the third test results; for chlorite, the 1.420nm peak shifted to 1.380nm, and the intensity of other peaks decreased significantly or even disappeared; for montmorillonite, the 1.700nm peak shifted to 1.000nm; a new peak appeared between 1.420nm and 1.000nm for the chlorite / montmorillonite interlayer minerals; and the peak of the illite / montmorillonite interlayer minerals shifted to 1.0nm. Of course, different clay tablets will yield different test results due to their different mineral compositions. For example, Figure 4 As shown, from top to bottom, these are the X-ray diffraction patterns of a clay slice after the first, second, and third tests. The peak with a visible angle of 8.84° remained unchanged in the three tests, which is characteristic of illite mineral diffraction peaks. The mineral peak at 12.29° remained unchanged in the first and second tests, but its intensity decreased significantly after the third test due to high-temperature burning, which is characteristic of kaolinite mineral diffraction peaks.

[0192] After determining the types of minerals, the content of each mineral is calculated and analyzed according to the corresponding calculation methods.
