Description

Technical Field

[0001] The present invention relates to the technical field of petroleum and natural gas, and in particular to an analysis device for shale oil and gas detection. Background Art

[0002] The exploration and development of shale oil and gas resources is a hot topic in the current energy industry. Due to its special geological conditions, traditional oil and gas resource analysis methods are not fully applicable to the detection of shale oil and gas. Therefore, the development of efficient and accurate shale oil and gas detection and analysis devices has become an urgent need in the industry. Such devices can effectively and accurately determine the oil and gas content in shale samples, providing a scientific basis for the evaluation and development of shale oil and gas resources.

[0003] The existing Chinese patent (Announcement No.: CN214200890U) proposes an analysis device for shale oil and gas detection, including a rectangular box, a rotating shaft is arranged through the middle of the bottom surface of the rectangular box, the rotating shaft is rotatably connected to the middle of the bottom surface of the rectangular box, a U-shaped shaft is fixedly arranged at the top of the rotating shaft, a driven gear is fixedly arranged at the bottom end of the rotating shaft, a plurality of blades are evenly fixedly arranged on the U-shaped shaft, a bearing ring is installed on the inner top surface of the rectangular box, a rotating drum is rotatably arranged in the bearing ring, a grid plate is fixedly arranged at the bottom surface port of the rotating drum, a plurality of through holes are evenly opened on the grid plate, and a rotating component is arranged between the rotating drum and the rectangular box.

[0004] The above technical solution improves the efficiency of shale oil and gas separation through the coordinated setting of the first motor and the second motor, thereby increasing the efficiency of shale oil and gas detection and analysis operations. However, bubbles are generated during the stirring process, and the bubbles occupy the space in the stirring barrel, reducing the contact area between oil, gas and liquid, thereby affecting the effective separation of oil and gas. Too many bubbles make the subsequent oil and gas processing process more complicated, requiring additional equipment and technology to remove the bubbles, increasing production costs. Therefore, we propose an analysis device for shale oil and gas detection. Summary of the invention

[0025] like Figure 1-3As shown, an analysis device for shale oil and gas detection includes a base 1, a mixing box 2 is arranged on the top of the base 1, a supporting leg 5 is arranged on the bottom of the base 1, an annular groove 11 is opened on the inner wall of the mixing box 2, a circular frame 6 is clamped in the annular groove 11, and an elastic string 7 is arranged in the circular frame 6, a knocking assembly 3 is arranged on the side of the top of the base 1 close to the mixing box 2, and the knocking assembly 3 includes a support plate 31, a fixed shaft 32 is rotatably connected to the support plate 31, a rotating disk 33 is connected to the fixed shaft 32, a first rotating shaft 34 is arranged on the rotating disk 33, a connecting rod 35 is connected to the first rotating shaft 34, a second rotating shaft 36 is arranged on the side of the connecting rod 35 away from the first rotating shaft 34, a knocking rod 37 is arranged on the side of the support plate 31 away from the fixed shaft 32, and the second rotating shaft 36 is fixed to the knocking rod 3 7, a support plate 38 is provided on the side of the support plate 31 away from the turntable 33, and a motor 39 is provided on the support plate 38, and the output end of the motor 39 is fixedly connected to the fixed shaft 32. Since bubbles are generated during the stirring process, the generation of bubbles will occupy the space in the stirring barrel, reduce the contact area between oil, gas and liquid, and thus affect the effective separation of oil and gas. By setting the knocking component 3, the motor 39 is turned on to drive the fixed shaft 32 to rotate, the fixed shaft 32 drives the turntable 33 to rotate, the turntable 33 drives the first rotating shaft 34 to rotate, the first rotating shaft 34 drives the connecting rod 35 to move, the connecting rod 35 drives the second rotating shaft 36 and the knocking rod 37 to knock on the outer wall of the mixing box 2, and the knocking force will be transmitted to the circular frame 6, thereby driving the elastic string 7 in the circular frame 6 to vibrate to eliminate the bubbles; Furthermore, Figure 2 As shown: a stirring assembly 4 is arranged on the top of the stirring box 2, and the stirring assembly 4 includes a rocker 41, a rotating rod 42 is fixedly connected to the bottom of the rocker 41, and a stirring rod 43 is arranged on the rotating rod 42. There are six stirring rods 43, and each three stirring rods 43 are arranged on both sides of the rotating rod 42 in a group. By arranging the stirring assembly 4, the shale oil inside is stirred, which can increase the contact area between the shale oil and the processing liquid, promote the effective separation of oil and gas, and thus improve the collection efficiency of oil and gas; The above solution also has the problem that when the knocking rod 37 is knocking, there is no limit, which may cause the knocking rod 37 to shake or deviate, such as Figure 3 As shown: a limiting assembly 8 is provided on one side of the support plate 31 close to the knocking rod 37, the limiting assembly 8 includes a first fixing plate 81, a screw 85 is threadedly connected to the first fixing plate 81, a fixing seat 82 is provided on the first fixing plate 81, a connecting member 83 is provided on the fixing seat 82, a clamping plate 84 is provided on the connecting member 83, a supporting rod 9 is provided on the top of the base 1, a second fixing plate 10 is provided on the top of the supporting rod 9, and the knocking assembly 3 is provided on the top of the second fixing plate 10.

Figure 4 As shown: an exhaust pipe 13 is arranged on one side of the top of the base 1 close to the rocker 41, a square plate 14 is arranged on one side of the top of the base 1 close to the exhaust pipe 13, a screw 15 is threadedly connected to the square plate 14, a baffle 16 is connected to the side of the screw 15 away from the square plate 14, and the baffle 16 is located at the top of the exhaust pipe 13. By arranging the screw 15 and the baffle 16, the exhaust pipe 13 is blocked during the stirring process to prevent air from entering the interior of the stirring box 2 and affecting the later detection and analysis results; Furthermore, Figure 2 As shown: a sleeve 44 is sleeved on the side of the stirring rod 43 away from the rotating rod 42, and a scraper 45 is fixedly connected to the side of the sleeve 44 away from the stirring rod 43. The inclination angle of the scraper 45 is set to 45 degrees.

[0026] Working principle: Figure 1 - Figure 4As shown, first, shale oil and treatment liquid are poured into the mixing tank through the provided oil filling port 17, and then the provided stirring assembly 4 is used to shake the rocker 41 to drive the rotating rod 42 and the stirring rod 43 provided thereon to stir, thereby increasing the contact area between the shale oil and the treatment liquid and promoting the effective separation of oil and gas. Since bubbles are generated during the stirring process, the generation of bubbles will occupy the space in the mixing tank, reducing the contact area between oil, gas and liquid, thereby affecting the effective separation of oil and gas. By providing the knocking assembly 3, the motor 39 is turned on to drive the fixed shaft 32 to rotate, the fixed shaft 32 drives the turntable 33 to rotate, the turntable 33 drives the first rotating shaft 34 to rotate, and the first rotating shaft 34 drives the connecting rod 3 5 movement, the connecting rod 35 drives the second rotating shaft 36 and the knocking rod 37 to knock on the outer wall of the mixing box 2, and the knocking force will be transmitted to the circular frame 6, thereby driving the elastic string 7 in the circular frame 6 to vibrate to eliminate the bubbles. By setting the limiting component 8, the knocking rod 37 is limited to prevent shaking and deviation during the knocking process. By setting the screw 15 and the baffle 16, the exhaust pipe 13 is blocked during the mixing process to prevent air from entering the inside of the mixing box 2 and affecting the later detection and analysis results. By setting the scraper 45, the inner wall of the mixing box 2 is cleaned, saving manpower for cleaning. Finally, the gas is discharged from the exhaust pipe 13, and the separated shale oil is discharged from the oil discharge pipe 12.
