Description

Technical Field

[0001] The utility model relates to the technical field of desanding cyclones, in particular to a drilling mud desanding cyclone. Background Art

[0002] The cyclone desander is based on the principle of centrifugal sedimentation and density difference. When water flows into the desander water inlet under a certain pressure, it generates a strong rotation motion. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water flows out from the hollow filter screen, thereby retaining the larger stones in the filter screen, thereby achieving the purpose of desandering. However, the existing drilling mud desander cyclone has some shortcomings when in use;

[0003] During drilling activities, a large amount of mud will be generated. In order to save energy and protect the environment, the mud needs to be recycled, so the sand and gravel in the mud need to be separated. However, the existing drilling mud desanding cyclone can only separate the sand and gravel from the mud by rotating and using centrifugal force. However, such operation can easily cause the sand and gravel to block the filter screen, resulting in low efficiency in separating the sand and gravel from the mud. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a drilling mud desanding cyclone to more accurately solve the problem that the filter screen is easily blocked by sand and gravel when the mud and sand and gravel are rotated and separated.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model proposes a drilling mud desanding cyclone, comprising an outer shell, a fixed plate is slidably arranged inside the outer shell, a filter screen is slidably arranged on the surface of the fixed plate, a column is fixedly arranged on the inner wall of the outer shell, a first gear is fixedly arranged on the surface of the filter screen, a rotating shaft is rotatably arranged inside the outer shell, a second gear is fixedly arranged on the surface of the rotating shaft, a first rotating member is fixedly arranged on the top of the rotating shaft, a second rotating member is fixedly arranged on the surface of the filter screen, ten groups of vertical rods are fixedly arranged at the bottom end of the second rotating member, and ten groups of rubber blocks are arranged on the surface of the first rotating member, the rubber blocks on the surface of the first rotating member correspond to the positions of the vertical rods at the bottom end of the second rotating member, and the rubber blocks will contact the vertical rods at the bottom end of the second rotating member when rotating, and can ensure that the second rotating member and the first rotating member can rotate alternately, thereby finally driving the filter screen to move up and down.

[0007] Furthermore, a support frame is fixedly provided on the outer surface of the shell, and a drive motor is fixedly provided on the surface of the support frame. The drive motor is fixedly connected to the rotating shaft, and the drive motor is used to drive the rotating shaft to rotate.

[0008] Furthermore, four groups of sliding rods are fixedly arranged on the surface of the fixed plate, and an annular sliding groove is fixedly arranged on the inner wall of the outer shell. The annular sliding groove on the inner wall of the outer shell is adapted to the sliding rod on the outer surface of the fixed plate, ensuring that the fixed plate can slide and move inside the annular sliding groove on the inner wall of the outer shell through the sliding rod.

[0009] Furthermore, a vertical rod is fixedly arranged inside the fixed plate, and a sliding block is fixedly arranged on the surface of the filter screen. The sliding block on the surface of the filter screen is slidably connected to the surface of the vertical rod inside the fixed plate, and a spring is provided to fix the sliding block on the surface of the filter screen and the fixed plate, thereby ensuring that the filter screen can drive the sliding block to move up and down inside the fixed plate, and the filter screen is pushed to reset by resetting the spring.

[0010] Furthermore, the top of the column is set to a conical structure, and the column is movably inserted into the bottom end of the filter screen. The conical structure can make it easier for the column to push the sand and gravel inside the filter screen, thereby preventing the sand and gravel from clogging the outlet of the filter screen.

[0011] Furthermore, the first gear and the second gear are meshed with each other, and the height of the second gear is greater than the height of the vertical rod inside the fixed plate, ensuring that the second gear can drive the first gear to rotate, and ensuring that the first gear can still mesh with the second gear when following the filter screen to move up and down.

[0012] Furthermore, a fixed plate is fixedly provided at the bottom end of the column, and four groups of circular notches are fixedly provided on the surface of the fixed plate. The fixed plate is fixedly provided on the inner wall of the outer shell, so that the mud filtered by the filter net can flow out from the circular notches on the surface of the fixed plate at the bottom end of the column.

[0013] Furthermore, the top of the filter screen is located outside the housing, so that the staff can directly pour the drilling mud from the top of the filter screen, which is convenient for loading.

[0014] Beneficial effects of the utility model:

[0015] The utility model drives the first gear and the second gear to mesh and rotate through the rotation of the rotating shaft, and drives the first rotating member and the second rotating member to mesh and rotate, so that the filter screen can be driven to rotate and also perform lifting movement, and the filter screen can push the sand and gravel inside the filter screen through the plugging of the columns when it is lifted and lowered, so as to avoid the sand and gravel blocking the discharge port, so that the filter screen is convenient for separating and filtering the mud and sand and gravel, and the whole operation only needs one driving motor to operate, so that the whole device has energy-saving effect and high-efficiency separation effect.
