Description

Technical Field

[0001] This utility model belongs to the field of oil-based mud treatment technology, and in particular relates to an oil-based mud treatment device that prevents adhesion to the wall. Background Technology

[0002] During oilfield extraction, a large amount of oil-based mud is generated, causing serious pollution to the surrounding environment. Furthermore, oil-based mud contains a significant amount of crude oil, and leaving it unattended would result in substantial resource waste. Therefore, separating and reusing the crude oil from the oil-based mud is a crucial step in oilfield extraction. One method for separating oil-based mud is by using an extractant to extract the crude oil from the mud. However, a current problem is that after crude oil extraction, some of the separated mud adheres to the inner wall of the extraction device, preventing it from being smoothly discharged. Therefore, it is necessary to solve the problem of mud adhering to the wall after extraction to ensure smooth production.

[0003] To address these issues, we provide an oil-based mud treatment device that prevents adhesion to the wall. Utility Model Content

[0004] The purpose of this invention is to provide an oil-based mud treatment device that prevents wall adhesion. By combining the wall scraping component and the extraction component, it solves the problem in the prior art where, after crude oil extraction, some of the separated mud adheres to the inner wall of the extraction device, preventing the mud from being smoothly discharged from the extraction device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to an oil-based mud treatment device for preventing wall adhesion, comprising an extraction assembly, a wall scraping assembly fixedly connected to the top of the inner cavity of the extraction assembly, the extraction assembly including an extraction tank, a drive motor fixedly connected to the top of the extraction tank, the output shaft of the drive motor penetrating into the inner cavity of the extraction tank and fixedly connected to a stirring rod, a bevel gear fixedly connected to the top of the surface of the stirring rod, the wall scraping assembly including a linkage fixedly connected to the top of the extraction tank, the bottom of the linkage penetrating into the inner cavity of the extraction tank and fixedly connected to a wall scraping ring, the surface of the wall scraping ring having rinsing holes, and water inlet pipes connected to both the front and rear ends of the top of the wall scraping ring, the top of the water inlet pipes penetrating into the top of the extraction tank and connected to an external water source.

[0007] The present invention is further configured such that the linkage includes a dual-output shaft motor fixedly connected to the top of the extraction tank, both ends of the dual-output shaft motor being fixedly connected to lead screws, a movable plate being threaded onto the surface of the lead screws, a bearing seat being fixedly connected to one side of the movable plate, the bottom of the bearing seat being slidably connected to the top of the extraction tank, a drive shaft being fixedly connected to the inner cavity of the bearing seat, a bevel gear being fixedly connected to one end of the drive shaft, the bevel gear meshing with the bevel gear, and a hexagonal hole being provided at the other end of the drive shaft.

The sliding fit between the hexagonal hole and the hexagonal prism allows axial expansion and contraction while transmitting torque, adapting to the lifting and lowering requirements of the scraper ring.

[0008] The present invention is further configured such that the inner cavity of the movable plate is provided with a threaded hole for use with the lead screw, and the threads on the surfaces of the two symmetrically designed lead screws are designed in opposite directions.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model combines mechanical scraping and fluid flushing to efficiently solve the problem of oil-based mud sticking to the tank wall. The scraping ring moves up and down through a linkage and rotates with the stirring rod to scrape the tank wall in all directions. At the same time, the flushing holes spray high-pressure flushing water to wash away the scraped mud in time. This combination technology significantly improves extraction efficiency and reduces the frequency of manual tank cleaning.

[0016] 2. The linkage of this utility model adopts a dual-output shaft motor-driven lead screw transmission. The synchronous and opposite movement of the moving plate is achieved through the reverse thread design.

[0028] Example 2

[0029] Please see Figure 1-5Based on Embodiment 1, the linkage 21 includes a dual-output shaft motor 211 fixedly connected to the top of the extraction tank 11. Both ends of the dual-output shaft motor 211 are fixedly connected to lead screws 212. A movable plate 213 is threaded onto the surface of the lead screws 212. A bearing seat is fixedly connected to one side of the movable plate 213. The bottom of the bearing seat is slidably connected to the top of the extraction tank 11. A transmission shaft 214 is fixedly connected to the inner cavity of the bearing seat. One end of the transmission shaft 214 is fixedly connected to a tapered [device / structure]. Gear 215 meshes with bevel gear 14. A hexagonal hole 216 is provided at the other end of drive shaft 14. A hexagonal prism 217 is inserted into the inner cavity of the hexagonal hole 216. Drive shaft 218 is fixedly connected to the other end of hexagonal prism 217. A bevel gear 3 219 is fixedly connected to the other end of drive shaft 218. A bevel gear 4 2110 meshes with the surface of bevel gear 3 219. A threaded tube 2111 is fixedly connected to the shaft center of bevel gear 4 2110. The inner cavity of 2111 is threaded with a second lead screw 2112. The inner cavity of the moving plate 213 is provided with a threaded hole for use with the first lead screw 212. The threads on the surfaces of the two symmetrically designed first lead screws 212 are designed in opposite directions. The surface of the second transmission shaft 218 is fixedly connected to the top of the extraction tank 11 through a bearing seat. Both sides of the top of the extraction tank 11 are provided with sliding grooves 2113. The inner cavity of the sliding grooves 2113 is slidably connected with a slider 2114.

The bottom of the support leg 17 is fixedly connected with a mounting base. The top of the back of the extraction tank 11 is connected to a feed hopper.

[0030] Specifically: The dual-output shaft motor 211 drives the lead screw 212, which in turn causes the moving plate 213 to move synchronously through the reverse thread, ensuring the synchronization of transmission on both sides. The sliding fit between the hexagonal hole 216 and the hexagonal prism 217 allows for axial expansion and contraction while transmitting torque, adapting to the lifting and lowering requirements of the scraper ring 22. When the lead screw 212 rotates, the left and right moving plates 213 move towards and away from each other, realizing the smooth lifting and lowering of the scraper ring 22.

[0031] The working principle of this utility model is as follows: the drive motor 12 drives the stirring rod 13 to rotate, and the extraction work is carried out by adding the extractant. After the extraction work is completed, the dual output shaft motor 211 drives the lead screw 212 to rotate. The lead screw 212 drives the moving plate 213 to move. The moving plate 213 drives the transmission shaft 214 to move through the bearing seat. The transmission shaft 214 drives the bevel gear 215 to mesh with the bevel gear 14, thus realizing the transmission of power. At this time, the transmission shaft 214 can drive the transmission shaft 215 through the hexagonal hole 216 and the hexagonal prism 217. When 218 rotates, the second transmission shaft 218 drives the threaded tube 2111 to rotate through the third bevel gear 219 and the fourth bevel gear 2110. The threaded tube 2111 drives the second lead screw 2112 to move downward. The second lead screw 2112 drives the scraper ring 22 to rise and fall synchronously, realizing continuous scraping of the tank wall. At the same time, the external water source enters the scraper ring 22 through the water inlet pipe 23 and sprays high-pressure water through the flushing hole. Combined with the mechanical movement of the scraper ring 22, the residual mud on the tank wall is thoroughly removed. The scraper plate 15 at the bottom of the stirring rod 13 pushes the deposited mud to the mud discharge pipe 16. The mud can be discharged by opening the valve.
