Detailed implementation manners

[0023] The following further elaborates on the present application in conjunction with the attached Figures 1-5 for a more detailed description of the present application.

[0024] The embodiment of the present application discloses a drilling mud treatment device. As Figure 1As shown in the figure, it includes a base plate 1. On the upper surface of the base plate 1, a mud bucket 2 is fixedly arranged. At the top of the mud bucket 2, a support plate 3 is fixedly arranged. At the top of the support plate 3 near the left end, an inclined power groove is fixedly arranged to prevent the U-shaped frame 7 from having a movement conflict with the side support plate 3. The U-shaped frame 7 is located on the inner wall of the power groove, and the width of the U-shaped frame 7 is smaller than the width of the power groove. At the top of one side of the support plate 3, a vertical plate 18 is fixedly arranged. In the middle of the vertical plate 18, a power plate 15 is rotatably arranged. At the bottom of the left end of the power plate 15, a pressure rod 16 is fixedly arranged. At the bottom of the pressure rod 16, a baffle 17 is slidably arranged. On the side of the baffle 17 away from the pressure rod 16, a sliding rod 5 is fixedly arranged. At the end of the sliding rod 5 away from the baffle 17, a water blocking plate 9 is fixedly arranged. In the middle of the water blocking plate 9, a water discharge hole is fixedly arranged, and the diameter of the water discharge hole is the same as the inner wall diameter of the blanking pipe 19. At the end of the water blocking plate 9, a U-shaped frame 7 is fixedly arranged. The U-shaped frame 7 is slidably sleeved on the outside of the valve plate 8. After the water discharge hole on the surface of the water blocking plate 9 moves a certain distance, it coincides with the blanking pipe 19 to realize adding additives as needed. One end of the water blocking plate 9 away from the sliding rod 5 is slidably inserted into the middle of the valve plate 8. The inside of the valve plate 8 is communicated with the connection part of the blanking pipe 19. The inner wall width of the valve plate 8 is the same as the thickness of the water blocking plate 9. The water blocking plate 9 slides inside the valve plate 8 to realize the opening and closing of the blanking pipe 19. The valve plate 8 is fixedly arranged at the middle position near the bottom of the blanking pipe 19.

[0025] Please refer to Figure 2 , at the top of the blanking pipe 19, an additive bucket 12 is fixedly arranged. The bottom of the additive bucket 12 is inclined. Setting the additive bucket 12 at the top of the blanking pipe 19 facilitates the smooth falling of the additive. Near the top position of the blanking pipe 19, a fixing ring 11 is fixedly sleeved. The fixing ring 11 ensures that the blanking pipe 19 can be stably placed. One end of the fixing ring 11 away from the blanking pipe 19 is fixedly arranged on the vertical plate 18. Near the bottom position of the blanking pipe 19, it is inclined to avoid the relatively fast falling speed of the additive, save the additive, and prevent waste. The bottom of the blanking pipe 19 passes through the bottom of the support plate 3 and is communicated with the top of the mud bucket 2.

[0026] Please refer to Figure 1 , at the bottom of the right end of the power plate 15, an eccentric wheel 10 is slidably arranged. At the middle position of one end of the eccentric wheel 10, a rotating shaft 13 is fixedly inserted. On the outer surface of the rotating shaft 13 located inside the mud pipe 14, stirring blades 20 are fixedly arranged. The edge position of the stirring blades 20 is in sliding contact with the inner wall of the mud pipe 14. The stirring blades 20 rotate under the gravity of the falling mud to realize the rotation of the rotating shaft 13 following it. The connection part between the rotating shaft 13 and the eccentric wheel 10 is two-thirds away from the center and is set away from the center of the eccentric wheel 10 to ensure that the eccentric wheel 10 forms an elliptical trajectory when rotating. The other end of the rotating shaft 13 passes through the vertical plate 18 and is rotatably inserted into the middle of the mud pipe 14. The bottom of the mud pipe 14 is communicated with the top of the mud bucket 2.

[0027] Please refer toFigure 2 A spring 4 is sleeved on the outer surface of the sliding rod 5. The top end of the spring 4 is fixedly arranged on one side of the baffle 17, and the end of the spring 4 is fixedly arranged in the middle of one side of the fixing plate 6. The middle of the fixing plate 6 is slidably sleeved on the outer surface of the sliding rod 5. One side of the fixing plate 6 is fixedly arranged on one side of the vertical plate 18. The spring 4 is arranged on the outer surface of the sliding rod 5, which is convenient for providing a reset power for the sliding rod 5 after movement.

[0028] The implementation principle of a drilling mud treatment device according to an embodiment of the present application is as follows: Pour the mud treatment additive into the interior of the additive barrel 12. The mud pipeline is communicated with the mud pipe 14. When the mud falls, the stirring piece 20 drives the rotating shaft 13 to rotate. While the rotating shaft 13 rotates, the eccentric wheel 10 rotates. Affected by the shape of the eccentric wheel 10 itself, the power plate 15 slidably connected to it swings. When the power plate 15 makes an arc-shaped movement, it pushes the baffle 17 and the sliding rod 5 to slide through the pressure rod 16. The sliding rod 5 drives the water blocking plate 9 to slide inside the valve plate 8. When the water discharge hole in the middle of the water blocking plate 9 moves to the position of the blanking pipe 19, the water discharge hole coincides with the blanking pipe 19, so that the additive is poured into the interior of the bottom mud barrel 2 through the blanking pipe 19. The reciprocating water blocking plate 9 prevents excessive addition of the additive. After the mud pouring stops, the rotating shaft 13 stops rotating, and at the same time the blanking pipe 19 is closed, and the additive stops being added, avoiding excessive addition and being able to achieve addition according to needs.

[0029] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
