Description
Technical Field
[0001] This utility model relates to the field of coal mining, and in particular to drilling with mud solid-liquid separation function. Background Technology
[0002] A drilling platform is a large piece of equipment used for onshore coal resource exploration and mining. Drilling mud solid-liquid separation refers to the process of separating solid particles from liquid components in drilling mud during coal mining operations. Drilling mud is an important medium used in the drilling process to cool the drill bit, carry cuttings, and stabilize the wellbore. However, it will mix with a large amount of cuttings and other solid impurities during use. The purpose of solid-liquid separation is to recover the liquid components in the mud for reuse, while treating solid waste, reducing environmental pollution, and improving drilling efficiency.
[0003] In existing drilling operations, the mud and cuttings mixture generated during drilling are directly transported through pipelines to a centrifugal vibrating screen for solid-liquid separation. The lack of a pretreatment structure leads to a heavy workload on the centrifugal vibrating screen and a reduced service life.
[0004] Therefore, in view of the problem that existing drilling operations lack a pretreatment structure for mud and cuttings mixtures, resulting in a heavy workload and reduced service life of centrifugal vibrating screens, there is an urgent need to design a new type of drilling system with mud solid-liquid separation function. Utility Model Content
[0005] In order to overcome the problem that the lack of a pretreatment structure for mud and rock cuttings mixtures during existing drilling operations leads to a heavy workload and reduced service life of centrifugal vibrating screens.
[0006] The technical solution of this utility model is as follows: a drilling platform with mud solid-liquid separation function, including a drilling platform; and a filter box, a filter frame, a rotating shaft, a first transmission disc and a transmission assembly. The filter box is installed on the left front side of the upper surface of the drilling platform. The filter frame is set inside the filter box. The rotating shaft is installed through the upper left corner of the front surface of the filter frame. The filter frame is rotatably connected to the filter box through the rotating shaft. The front end of the rotating shaft passes through the front side wall of the filter box and is connected to the first transmission disc. The transmission assembly is installed on the left side of the front surface of the filter box.
[0007] Preferably, by setting up a filter box and a filter frame, the mud and cuttings mixture generated during drilling platform operations is discharged into the filter frame through a pipeline. The filter frame filters the cuttings in the mud and cuttings mixture. Then, the transmission component drives the first transmission disc to rotate. When the first transmission disc rotates, it drives the rotating shaft to rotate, thereby causing the left end of the filter frame to rotate, resulting in a tilting action of the filter frame. This facilitates the cleaning of the cuttings inside the filter frame by the workers, thus achieving the purpose of pre-treatment of the mud and cuttings mixture. This reduces the workload of the subsequent centrifugal vibrating screen and solves the problem that in existing drilling operations, the mud and cuttings mixture generated during drilling is directly transferred to the centrifugal vibrating screen for solid-liquid separation through pipelines. The lack of a pre-treatment structure leads to a heavy workload for the centrifugal vibrating screen and a reduced service life.
[0008] Preferably, the transmission assembly includes a mounting platform, a first drive motor, a second transmission disc, and a belt; the mounting platform is fixed to the left side of the front surface of the filter box, the first drive motor is mounted on the upper surface of the mounting platform, the output end of the first drive motor is connected to the second transmission disc, and the outer surfaces of the second transmission disc and the first transmission disc are fitted with belts.
[0009] Preferably, a fixing plate is installed on the upper left side surface of the filter box, and two symmetrical support plates are installed on the upper surface of the fixing plate. A drive shaft is rotatably connected between the two support plates. Two winding reels are installed on the outer surface of the drive shaft. Two connectors are installed on the right side of the top surface of the filter frame. One end of a steel cable is wound on the outer surface of the winding reel, and the other end of the steel cable is connected to the connector.
[0010] Preferably, the bottom surface of the fixing plate is provided with one end of the support leg on both the front and rear sides, and the other end of the support leg is welded and fixed to the filter box.
[0011] Preferably, a drain pipe is installed on the lower part of the front surface of the filter box, and a pump is installed at the front end of the drain pipe.
[0012] Preferably, limit blocks are installed on the upper part of both the front and rear surfaces of the filter frame, and limit grooves are opened on both the front and rear sides of the top surface of the filter box.
[0013] Preferably, the front end of the drive shaft passes through the front support plate and is connected to a driven gear. The front surface of the front support plate is located below the driven gear and a second drive motor is provided. The output end of the second drive motor is connected to a driving gear, and the driving gear meshes with the driven gear.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting up a filter box and filter frame, the mud and rock cuttings mixture generated during drilling platform operations will be discharged through pipelines into the filter frame for preliminary filtration. Then, the transmission component drives the first transmission disc to rotate. When the first transmission disc rotates, it drives the rotating shaft to rotate, thereby causing the left end of the filter frame to rotate, resulting in a tilting action of the filter frame. This facilitates the cleaning of rock cuttings inside the filter frame by the operators, thus achieving the purpose of pre-treatment of the mud and rock cuttings mixture. This reduces the workload of the subsequent centrifugal vibrating screen and solves the problem that in existing drilling operations, the mud and rock cuttings mixture generated during drilling is directly transferred to the centrifugal vibrating screen for solid-liquid separation through pipelines. The lack of a pre-treatment structure leads to a heavy workload for the centrifugal vibrating screen and a reduced service life. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1-4This utility model provides an embodiment of a drilling platform with mud solid-liquid separation function, including a drilling platform 1; it also includes a filter box 2, a filter frame 3, a rotating shaft 4, a first transmission disc 5, and a transmission assembly. The filter box 2 is installed on the upper left front side of the upper surface of the drilling platform 1. A filter frame 3 is disposed inside the filter box 2. A rotating shaft 4 is inserted through the upper left corner of the front surface of the filter frame 3. The filter frame 3 is rotatably connected to the filter box 2 via the rotating shaft 4. The front end of the rotating shaft 4 penetrates the front wall of the filter box 2 and is connected to the first transmission disc 5. A transmission assembly is installed on the left side of the front surface of the filter box 2. During drilling platform 1 operations, the mud and rock cuttings mixture generated is discharged into the filter frame 3 through a pipe. The filter frame 3 filters the rock cuttings in the mud and rock cuttings mixture. Then, the transmission assembly drives the first transmission disc 5 to rotate. When the first transmission disc 5 rotates, it drives the rotating shaft 4 to rotate, thereby causing the left end of the filter frame 3 to rotate, resulting in a tilting action of the filter frame 3. This makes it easier for the staff to clean the rock cuttings inside the filter frame 3, thus achieving the purpose of pre-treatment of the mud and rock cuttings mixture and reducing the workload of the subsequent centrifugal vibrating screen.
[0023] Please see Figures 1-4 In this embodiment, the transmission assembly includes a mounting platform 61, a first drive motor 62, a second transmission disc 63, and a belt 64. The mounting platform 61 is fixed to the left side of the front surface of the filter box 2. The first drive motor 62 is mounted on the upper surface of the mounting platform 61. The output end of the first drive motor 62 is connected to the second transmission disc 63. A belt 64 is fitted onto the outer surface of the second transmission disc 63 and the first transmission disc 5. By setting the first drive motor 62, its output end will drive the second transmission disc 63 to rotate during operation, thereby driving the first transmission disc 5 to rotate in cooperation with the belt 64, thus achieving automatic tilting of the filter frame 3. A fixing plate 7 is installed on the upper left side surface of the filter box 2. Two symmetrical supports are installed on the upper surface of the fixing plate 7. The support plate 8 is rotatably connected to the two support plates 8 by a drive shaft 9. Two winding discs 10 are installed on the outer surface of the drive shaft 9. Two connectors 12 are installed on the right side of the top surface of the filter frame 3. One end of a steel cable 11 is wound around the outer surface of the winding disc 10. The other end of the steel cable 11 is connected to the connector 12. By setting the drive shaft 9, the winding disc 10 can wind the steel cable 11 when the drive shaft 9 rotates. When the steel cable 11 is wound, it will drag the connector 12, thereby assisting the filter frame 3 to tilt and improving the stability during operation. The bottom surface of the fixed plate 7 is provided with one end of the support leg 13 on both the front and rear sides. The other end of the support leg 13 is welded and fixed to the filter box 2. By setting the support leg 13, the installation strength of the fixed plate 7 can be increased and its installation stability can be improved.
[0024] Please see Figures 1-4In this embodiment, a drain pipe 14 is installed on the lower front surface of the filter box 2, and a pump 15 is installed at the front end of the drain pipe 14. By setting the drain pipe 14 and the pump 15, the separated slurry can be pumped to the centrifugal vibrating screen operating position by the operation of the pump 15 for secondary treatment. Limiting blocks 16 are installed on the upper front and rear surfaces of the filter frame 3, and limiting grooves 17 are opened on the front and rear sides of the top surface of the filter box 2. By setting the limiting blocks 16 and the limiting grooves 17, when the filter frame 3 is reset, the limiting blocks 16 will contact the limiting grooves 17, thereby preventing the filter frame 3 from continuing to rotate and ensuring that it can be processed. In a stable working position, the front end of the drive shaft 9 passes through the front support plate 8 and is connected to the driven gear 20. The front surface of the front support plate 8 is located below the driven gear 20 and a second drive motor 18 is set there. The output end of the second drive motor 18 is connected to the drive gear 19. The drive gear 19 meshes with the driven gear 20. By setting the second drive motor 18, its output end will drive the drive gear 19 to rotate during operation. When the drive gear 19 rotates, it will drive the driven gear 20 that it meshes with to rotate synchronously, thereby driving the drive shaft 9 to rotate, so as to realize the automatic winding and unwinding of the steel cable 11.
[0025] During operation, the first drive motor 62 drives the second transmission disc 63 to rotate, which, in conjunction with the belt 64, drives the first transmission disc 5 to rotate, thus automatically tilting the filter frame 3. The drive shaft 9, when rotating, allows the winding disc 10 to wind the steel cable 11. As the cable 11 is wound, it drags the connector 12, assisting in tilting the filter frame 3 and improving stability during operation. The support legs 13 increase the installation strength of the fixing plate 7, improving its installation stability. The drain pipe 14 and pump 15 are also connected. The separated slurry can be pumped to the centrifugal vibrating screen operating position by the operation of pump 15 for secondary treatment. By setting limit block 16 and limit groove 17, when the filter frame 3 is reset, the limit block 16 will contact the limit groove 17, thereby preventing the filter frame 3 from continuing to rotate and ensuring that it can be in a stable operating position. By setting the second drive motor 18, its output end will drive the drive gear 19 to rotate during operation. When the drive gear 19 rotates, it will drive the driven gear 20 meshing with it to rotate synchronously, thereby driving the transmission shaft 9 to rotate, so as to realize the automatic winding and unwinding of the steel cable 11.
[0026] Through the above steps, by setting up filter box 2 and filter frame 3, the mud and rock cuttings mixture generated during drilling platform 1 operation will be discharged through pipeline into the filter frame 3 for preliminary filtration. Then, the transmission component drives the first transmission disc 5 to rotate. When the first transmission disc 5 rotates, it can drive the rotating shaft 4 to rotate, thereby causing the left end of the filter frame 3 to rotate, making the filter frame 3 tilt. This makes it easier for the staff to clean the rock cuttings inside the filter frame 3, thus achieving the purpose of pre-treatment of the mud and rock cuttings mixture, reducing the workload of the subsequent centrifugal vibrating screen. This solves the problem that in existing drilling operations, the mud and rock cuttings mixture generated during drilling is directly transmitted to the centrifugal vibrating screen through pipeline for solid-liquid separation, lacking a pre-treatment structure, resulting in a heavy workload and reduced service life of the centrifugal vibrating screen.
