Description

Technical Field

[0001] The invention relates to the technical field of rock sample slice preparation, and in particular to an integrated device for preparing granular rock sample slices. Background Art

[0002] In geological exploration and oil and gas drilling, researchers need to prepare rock slices from drilled rock samples for petrology, mineralogy and microscopic component analysis and testing. Due to the complex geological conditions, in many cases, the rock layers in the strata have not been consolidated into rocks. Only rock cuttings samples can be obtained during the drilling process, and it is difficult to directly prepare rock slices from them. In this case, the rock cuttings samples are usually collected and ground, and then filled into plastic tubes; the rock samples are bonded by dripping glue into the plastic tubes; and then the rock samples consolidated in the plastic tubes are cut and ground. This preparation method has the following main problems: (1) The process of glue infiltrating into the cuttings is very slow during the glue injection process, and glue needs to be added multiple times, resulting in low preparation efficiency; (2) Due to the presence of air between the cuttings particles, it is difficult for the glue to completely penetrate into the bottom of the plastic tube. The cuttings samples in the middle and lower parts of the plastic tube usually have a low degree of adhesion, resulting in poor thin-section preparation effect; (3) During the thin-section preparation process, the rock samples need to be sent to different equipment for processing, such as crushers and grinding machines, which occupy a lot of space; at the same time, this preparation method is time-consuming and labor-intensive, and it is difficult to meet the needs of rapid on-site preparation of large quantities of rock thin sections in the field and on offshore drilling platforms. Therefore, it is necessary to develop an integrated device for preparing thin sections of granular rock samples.

[0031] An integrated device for preparing thin slices of granular rock samples comprises a base 1, three groups of hydraulic cylinders 2 arranged in an annular shape and at equal intervals are fixedly installed on the top of the base 1, annular plates 3 are fixedly installed on the telescopic ends of the three groups of hydraulic cylinders 2, a crushing mechanism 4 is fixedly installed inside the annular plates 3, an equipment barrel 5 is fixedly installed on the top of the base 1, and the equipment barrel 5 is located below the crushing mechanism 4, a barrel cover 6 is threadedly connected to the outer periphery of the top of the equipment barrel 5, and seven groups of evenly arranged silo barrels 7 are threadedly connected to the top of the barrel cover 6, and the bottoms of the seven groups of silo barrels 7 are all threadedly connected to bottom covers 8, and the bottom wall of the bottom cover 8 is provided with multiple groups of evenly arranged air permeable grooves 9, and one side of the surface of the equipment barrel 5 is fixedly connected to an air outlet pipe 1 0, the tail end of the air outlet pipe 10 is fixedly connected to a vacuum pump 11, and the vacuum pump 11 is fixedly installed on the top of the base 1 by screws, the front of the equipment cylinder 5 is fixedly connected to a pressure gauge 12, and the pressure gauge 12 is electrically connected to the vacuum pump 11, the other side of the surface of the equipment cylinder 5 is fixedly connected to a conduit 13, the outer surface of the conduit 13 is fixedly connected to a control valve 14, the top of the annular plate 3 is fixedly installed with a programmable temperature-controlled heating cylinder 15, the bottom of the programmable temperature-controlled heating cylinder 15 is fixedly connected with a derivation mechanism 16, and the bottom of the derivation mechanism 16 passes through the interior of the annular plate 3, the top of the base 1 is fixedly installed with a cutting and grinding mechanism 17, and the cutting and grinding mechanism 17 is located on one side of the equipment cylinder 5.

[0032] By putting the rock blocks / rock cuttings into the space inside the crushing mechanism 4 and starting the crushing mechanism 4, the rock blocks / rock cuttings are automatically crushed into fine particles, and then the rock particles are put downward into the space formed by the silo tube 7 and the bottom cover 8 to cover the multiple groups of air permeable grooves 9 opened on the bottom wall of the bottom cover 8. The silo tube 7 and the glue injection pipeline are made of polytetrafluoroethylene material, which can effectively prevent the glue from solidifying in these areas. At the same time, the program temperature control heating tube 15 is operated to heat the glue such as fir glue loaded in its space. At this time, by running the vacuum pump 11, it is prompted to perform a vacuum operation on the space enclosed by the equipment tube 5 and the tube cover 6, so that the gas inside the equipment tube 5 is led out to the inside of the vacuum pump 11 along the outlet pipe 10, and then discharged to the outside. At the same time, the conduit 13 is used to monitor the air pressure value inside the space of the equipment tube 5 in real time, so that the actual air pressure value monitored inside the space of the equipment tube 5 reaches the set air pressure value. Stop the operation of the vacuum pump 11, and perform vacuuming in the equipment tube 5 Before vacuuming, the control valve 14 at the conduit 13 is in a closed state. Before vacuuming, the three groups of hydraulic cylinders 2 are synchronously extended upward to generate an upward driving force for the annular plate 3, thereby driving the crushing mechanism 4 to move upward a set distance as a whole, so that the distance between the bottom of the crushing mechanism 4 and the seven groups of silo tubes 7 is gradually enlarged. At this time, the export mechanism 16 is manually adjusted so that the tail end of the export mechanism 16 is aligned with the seven groups of silo tubes 7 in sequence, and when aligned, the export mechanism 16 is in a cleared state, and then the glue such as fir glue heated in the space of the program temperature-controlled heating tube 15 is exported in a set amount along the export mechanism 16 to the space inside the seven groups of silo tubes 7 in sequence, and then the glue and rock particle assembly after cooling and solidification in the space of the silo tube 7 is removed and placed in the space of the cutting and grinding mechanism 17 for cutting and grinding operations. Based on the above operations, the integrated operation of rock sample slices can be realized, and then the efficiency and effect of the overall operation can be effectively improved.

[0033] The structure of the pulverizing mechanism 4 includes a pulverizing cylinder 18, a sealing cover 19, a serrated vertical cylinder 20, a driving motor 21, a rotating shaft 22 and a pulverizing gear cone 23. The sealing cover 19 is threadedly sleeved on the outer periphery of the top of the pulverizing cylinder 18. The serrated vertical cylinder 20 is fixedly installed on the inner wall of the pulverizing cylinder 18. The driving motor 21 is fixedly installed on the top of the sealing cover 19. The rotating shaft 22 is fixedly connected to the output end of the driving motor 21. The outer surface of the rotating shaft 22 is fixedly sleeved with a pulverizing gear cone 23, and the diameter of the pulverizing gear cone 23 gradually increases from top to bottom. The pulverizing gear cone 23 is located inside the space enclosed by the serrated vertical cylinder 20. The structure of the pulverizing mechanism 4 also includes a grinding cylinder 24, a first sieve plate 25, a second sieve plate 26, a funnel tube 27 and a quantitative valve. The grinding cylinder 24 is fixedly installed On the inner wall of the annular plate 3, the grinding cylinder 24 and the crushing cylinder 18 are connected to each other, the first sieve plate 25 is fixedly installed on the bottom of the inner wall of the crushing cylinder 18, the second sieve plate 26 is fixedly installed on the inner wall of the grinding cylinder 24, and the bottom of the rotating shaft 22 is movably fitted on the top of the second sieve plate 26, the number of funnel tubes 27 is seven groups, and the seven groups of funnel tubes 27 are evenly fixed on the bottom of the grinding cylinder 24. The structure of the crushing mechanism 4 also includes a sleeve 28, a T-shaped round rod 29 and a grinding roller 30. The sleeve 28 is fixedly sleeved on the outer surface of the rotating shaft 22 by screws, the T-shaped round rod 29 is fixedly installed on the outer surface of the sleeve 28, the grinding roller 30 is rotatably sleeved on the outer surface of the T-shaped round rod 29, and the outer surface of the grinding roller 30 is movably fitted with the top of the second sieve plate 26.

[0034] After the rock blocks / rock cuttings are put into the space inside the crushing cylinder 18, the driving motor 21 is operated to drive the rotating shaft 22 to rotate in the set direction at a set speed, and then drive the crushing gear cone 23 to rotate accordingly, so as to crush the rock blocks / rock cuttings between the crushing gear cone 23 and the sawtooth vertical cylinder 20. Since the distance between the two gradually decreases from top to bottom, the rock blocks / rock cuttings between the two are broken down into smaller and smaller pieces during the process of falling down, and then the crushed rock blocks / rock cuttings fall onto the first screening plate 25. When the particle diameter is smaller than the diameter of the circular groove opened on the surface of the first screening plate 25, such rock particles directly fall down to the second screening plate 26. On the contrary, the rock with a larger particle diameter will be reserved on the first screening plate 25, waiting to be further crushed by the crushing gear cone 23 and the sawtooth vertical cylinder 20. As the rotating shaft 22 rotates, it can pass through the sleeve 2 8 drives the T-shaped round rod 29 and the grinding roller 30 to rotate together with the center of the second screening plate 26 as a fixed point, so as to crush the rock particles on the second screening plate 26, thereby further improving the effect of rock block / rock cuttings decomposition, and because the grinding roller 30 and the T-shaped round rod 29 are in a movable sleeve combination state, when the grinding roller 30 follows the rotation of the rotating shaft 22 to crush the rock particles on the second screening plate 26, the grinding roller 30 is subjected to the reaction force of the rock particles, and can rotate along the T-shaped round rod 29. When the diameter of the rock particles on the second screening plate 26 is small enough, it can fall down into the space of the seven groups of funnel tubes 27. Afterwards, when it is necessary to introduce the rock particles in the space of the seven groups of funnel tubes 27 into the space of the seven groups of silo tubes 7, the quantitative valve is opened to make the interior of the funnel tube 27 unblocked, so that the rock particles in its space are conveniently transferred to the silo tube 7 by a set amount.

[0035] The structure of the export mechanism 16 includes an upright tube 31, a locking sleeve 32, a telescopic tube 33, a bending tube 34, a solenoid valve 35 and a telescopic double tube 36.

The structure of the export mechanism 16 also includes a connecting ring 37 and a stirring rod 38. The connecting ring 37 is fixedly installed at the tail end of the telescopic double tube 36. The inner wall of the connecting ring 37 is fixedly connected with a rubber sheet. The stirring rod 38 is fixedly inserted in the inside of the rubber sheet. The telescopic double tube 36 gradually tilts downward from front to back.

[0036] By applying a rotational force in a set direction to the engaging sleeve 32, the telescopic tube 33, the bending tube 34 and the telescopic double tube 36 are driven to rotate, so as to adjust the angular position corresponding to the rear end of the telescopic double tube 36, and cooperate with applying a pulling force to the telescopic double tube 36 to extend or shorten its comprehensive length, thereby adjusting the position corresponding to the rear end of the telescopic double tube 36 on the top surface of the cylinder cover 6. At the same time, when the telescopic tube 33 is subjected to a pulling force or an extruding force, it can adjust the overall height of the outlet mechanism 16. The adjustment of its angle, length and height can make the rear end of the telescopic double tube 36 correspond to the seven groups of silo tubes 7 in sequence. Then, by opening the solenoid valve 35, the glue inside the space of the program temperature controlled heating tube 15 can be guided along the outlet mechanism 16 to the interior of the space of the seven groups of silo tubes 7 in sequence. After the glue is injected into the interior of a single silo tube 7, the stirring rod 38 is manually driven to shake, so that its bottom is stirred inside the space of the silo tube 7, thereby effectively improving the uniformity of mixing between the glue and the rock particles.

[0037] The structure of the cutting and grinding mechanism 17 includes an N-shaped frame 39, an electric telescopic rod 40, a cutting assembly 41, a grinding assembly 42 and a grinding pad 43.

The structure of the grinding mechanism 17 also includes a limiting baffle 44, a movable baffle 45, a square plate 46, a threaded column 47, a combined disc, a combined plate 48 and an electric push rod 49. The limiting baffle 44 and the square plate 46 are both fixedly mounted on the bottom wall of the N-type frame 39, and the square plate 46 is located on one side of the limiting baffle 44. The threaded column 47 threads through the interior of the square plate 46. The combined disc is rotatably engaged with the tail end of the threaded column 47. The movable baffle 45 is fixedly mounted on one side of the combined disc. The combined plate 48 is fixedly mounted on the bottom wall of the N-type frame 39, and the combined plate 48 is located in front of the limiting baffle 44. The electric push rod 49 is fixedly mounted on the back of the combined plate 48.

[0038] After the glue and rock particle combination cooled and solidified inside the space of the silo tube 7 is removed, it is placed between the limiting baffle 44 and the movable baffle 45 inside the space of the N-shaped frame 39, and the back of this combination is in the same position as the back of the limiting baffle 44. Then, the threaded column 47 is manually rotated to move it along the square plate 46 toward the direction of the limiting baffle 44, and a pushing force toward one side is applied to the movable baffle 45 through the combined disc, so that the movable baffle 45 can clamp the glue and rock particle combination between the two with the limiting baffle 44. Then, the electric push rod 49 is operated to cause the electric push rod 49 to extend outward a set distance at a time, and then the cutting assembly 41 and one of the electric telescopic rods 40 are operated to cut the combination beyond the back of the limiting baffle 44, and then the cut rock sample slice is placed on the grinding pad 43, and the grinding assembly 42 and another group of electric telescopic rods 40 are started to grind and polish the rock sample slice.

[0039] Working principle: by putting the rock blocks / rock cuttings into the space inside the crushing mechanism 4, and running the driving motor 21, the crushing gear cone 23 is driven to rotate through the rotating shaft 22, so as to crush the rock blocks / rock cuttings between the crushing gear cone 23 and the sawtooth vertical cylinder 20, and then the rock particles that meet the first standard fall down along the first screening plate 25 to the second screening plate 26, and as the rotating shaft 22 rotates, the sleeve 28 can drive the T-shaped round rod 29 and the grinding roller 30 to the second screening plate 26. 6 is rotated with the center of the circle as a fixed point to crush the rock particles on the second sieve plate 26, which can further decompose the rock particles, and then open the quantitative valve to make the interior of the funnel tube 27 unblocked, so that the rock particles are dropped downward into the space formed by the silo body tube 7 and the bottom cover 8 to cover the multiple groups of air-permeable grooves 9 opened on the bottom wall of the bottom cover 8, and then the hydraulic cylinder 2 is extended upward to drive the annular plate 3 and the crushing mechanism 4 to move upward by a set distance as a whole, and then the vacuum pump 11 is operated to cause it to be directed to the The space enclosed by the equipment cylinder 5 and the cylinder cover 6 is evacuated, so that the gas inside the equipment cylinder 5 is discharged into the vacuum pump 11 along the outlet pipe 10 and then discharged outwardly. At the same time, the air pressure value inside the space of the equipment cylinder 5 is monitored in real time in cooperation with the conduit 13, so that the vacuum pump 11 is stopped when the actual air pressure value monitored inside the space of the equipment cylinder 5 reaches the set air pressure value. When evacuating, the outlet mechanism 16 is manually adjusted so that the tail end of the outlet mechanism 16 is aligned with the seven groups of bin body cylinders 7 in sequence, and when aligned, the outlet mechanism 16 is in a cleared state, and then the heated fir glue and other glues in the space of the program temperature-controlled heating cylinder 15 are discharged into the space of the seven groups of bin body cylinders 7 in sequence along the outlet mechanism 16. Then, after the glue and rock particle assembly in the space of the bin body cylinder 7 is cooled and solidified, it is removed and placed in the space of the cutting and grinding mechanism 17 for cutting and grinding operations. Based on the above operations, the integrated operation of rock sample slices can be realized, and then the efficiency and effect of the overall operation can be effectively improved.
