Description

Technical Field

[0001] The present application relates to the technical field of environmental protection treatment of deep-sea drilling mud, and in particular to a deep-sea drilling mud solid-liquid separation device. Background Art

[0002] In deep-sea drilling operations, mud solid-liquid separation is a crucial step in ensuring drilling safety and environmental protection. With the continuous development of offshore oil and gas resources, the requirements for mud processing equipment are becoming increasingly stringent.

[0003] Currently, the most common method for solid-liquid separation in slurries is chemical flocculation, which promotes particle aggregation and accelerates sedimentation by adding chemicals. This method is suitable for various types of slurries. To facilitate slurry input and optimize separation, the separation chamber is typically positioned vertically, allowing solids to sink under gravity. The chamber is then flipped from its vertical position to a horizontal position to facilitate the addition of untreated slurry and minimize the impact on the chamber bottom caused by the high slurry input height.

[0004] However, since the cylinder's flipping drive is completed by a single pull rod, it requires greater power support in actual applications, has poor reliability, and is prone to equipment failure, affecting normal operation.

[0005] The above-mentioned related technologies have the defect that the reliability of the cylinder flipping during the solid-liquid separation process is insufficient. Summary of the Invention

[0006] In order to improve the problem of insufficient reliability of cylinder flipping during the solid-liquid separation process, the present application provides a deep-sea drilling mud solid-liquid separation device.

[0007] The deep-sea drilling mud solid-liquid separation device provided in this application adopts the following technical solution: 4. The liquid dispensing device of claim 1, wherein the lifting mechanism comprises a lifting mechanism, wherein the lifting mechanism comprises a lifting mechanism, a lifting mechanism comprising a first port, a second port, and a second port, wherein the lifting mechanism comprises a lifting mechanism, a lifting mechanism and a lifting mechanism. The cam is connected to the support member by a sliding bearing, and the sliding bearing has a first end connected to the support member and a second end connected to the support member, and the second end of the cam is connected to the support member by a sliding bearing.

[0008] By adopting the above-mentioned technical solution, the deep-sea drilling mud solid-liquid separation device can achieve efficient solid-liquid separation of mud and has good operational flexibility and stability. A stirring mechanism and a drug-feeding mechanism are installed inside the cylinder. After the drug-feeding mechanism adds liquid medicine, the stirring mechanism can fully mix the mud, promote the rapid sedimentation of solid particles in the mud, and improve the efficiency of solid-liquid separation. Flexible operating mode: The design of the conversion mechanism allows the cylinder to freely switch between vertical and horizontal states. When mud needs to be input, the cylinder can automatically adjust to a horizontal position to facilitate mud injection; when in operation, the cylinder returns to a vertical position to ensure a smooth separation process. The provision of a support mechanism and supporting parts ensures the stability and reliability of the entire device, preventing accidental movement or tilting during use, and improving the safety performance of the equipment. The collection mechanism is located below the cylinder and can directly receive the separated solid matter, facilitating subsequent processing and cleaning, while also helping to maintain a clean and tidy on-site environment. When the cylinder needs to be converted from a vertical state to a horizontal state, the pushing block can first push the collecting mechanism to offset to the side of the cylinder away from the telescopic member, and then continue to push the second end of the cylinder. At the same time, the pulling member pulls the first end of the cylinder, causing the cylinder to rotate around the hinge point with the support mechanism. Finally, the first end of the cylinder abuts against the supporting member, while the pushing block supports the second end of the cylinder so that it is in a horizontal position. This process not only ensures that the cylinder completes the posture conversion smoothly, but also improves the safety and convenience of operation. When the cylinder needs to be restored from a horizontal state to a vertical state, since there is a certain distance between the second end of the cylinder and the pushing block, under the action of the pulling member, the second end of the cylinder can smoothly push the pushing block to move, thereby cooperating with the telescopic member to provide sufficient power for the pulling member to achieve efficient and stable flipping of the cylinder.

[0009] Optionally, the transmission assembly includes a first rack, a gear and a second rack, the first rack and the second rack are both slidably connected to the support mechanism, the gear is rotatably connected to the support mechanism, the first rack and the second rack are arranged on opposite sides of the gear, the first rack and the second rack are both engaged with the gear, the moving directions of the first rack and the second rack are opposite, the telescopic end of the telescopic member is connected to one end of the first rack away from the collecting mechanism, the other end of the first rack is connected to the pushing block, and the second rack is hinged to the first end of the pulling member.

[0010] By adopting the above-mentioned technical solution, the movement of the push block and the pull member can be precisely controlled. Specifically, when the position of the cylinder needs to be adjusted, the telescopic end of the telescopic member pushes the first rack toward the collection mechanism. The telescopic movement of the telescopic member is transmitted to the push block through the first rack, allowing the push block to slide smoothly on the support mechanism and, in turn, push the collection mechanism and the second end of the cylinder, causing the cylinder to tilt smoothly. Due to the meshing of the first rack and the gear, the movement of the first rack drives the gear to rotate. As the gear rotates, the second rack moves away from the collection mechanism under the action of the gear. The second rack pulls the first end of the pull member through a hinged relationship, and the second end of the pull member correspondingly pulls the first end of the cylinder, causing the cylinder to rotate about the hinge point with the support mechanism. At the same time, the meshing action of the second rack and the gear ensures the effective linkage of the pull member, causing the first end of the cylinder to be pulled and flipped, ultimately turning the cylinder from a vertical state to a horizontal state, facilitating the input and processing of mud. In this process, the design of the transmission assembly ensures coordinated action between the various components, improving the operational stability and reliability of the device.

[0011] Optionally, the pushing block includes a first pushing part and a second pushing part, the first pushing part is arranged on the side of the second pushing part close to the collecting mechanism, the top height of the first pushing part is lower than the lowest point of the cylinder in the vertical state, and the top height of the second pushing part is higher than the lowest point of the cylinder in the vertical state.

[0012] By adopting the above technical solution, the first and second pushing parts are located at different heights, allowing the pushing block to push the collection mechanism and the cylinder separately at different stages. This design ensures more precise and reliable movement during the conversion process. The top height of the first pushing part is lower than the lowest point of the cylinder, preventing collision or interference with the cylinder during the pushing process, ensuring the safety and stability of the equipment operation. The top height of the second pushing part is higher than the lowest point of the cylinder. When the cylinder needs to be pushed, it can effectively apply thrust, allowing the cylinder to rotate smoothly around the hinge point, completing the rapid conversion from vertical to horizontal state, and improving work efficiency.

[0013] Optionally, a drug dispensing port is opened on one side of the barrel, and the drug dispensing mechanism cooperates with the drug dispensing port. The drug dispensing mechanism includes a support frame, a driving member, a bidirectional screw, a guide rod, an inner sealing block and an outer sealing block. One end of the support frame is connected to the barrel, and the other end of the support frame is connected to the driving member. The output end of the driving member is connected to the bidirectional screw. The inner sealing block and the outer sealing block are both screwed to the bidirectional screw. The inner sealing block is arranged in the barrel, and the outer sealing block is arranged outside the barrel. The guide rod is mounted on the side wall, and the bidirectional screw is parallel to the guide rod and extends in a direction perpendicular to the length of the cylinder. The inner sealing block and the outer sealing block are both slidably connected to the guide rod, and the driving member drives the bidirectional screw to rotate, and can synchronously drive the inner sealing block and the outer sealing block to move toward or away from each other. The inner sealing block and the outer sealing block move toward each other to seal the medicine dispensing port, and the inner sealing block and the outer sealing block move away from each other to open the medicine dispensing port so as to dispense medicine through the medicine dispensing port.

[0014] By adopting the above technical solution, the automatic opening and closing of the drug dispensing port can be realized, thereby improving the degree of automation of the equipment. The design of the inner sealing block and the outer sealing block ensures the tight sealing of the drug dispensing port, prevents drug leakage, and ensures the safety and sanitary conditions of the working environment. At the same time, the coordinated use of the bidirectional screw and the guide rod makes the movement of the inner sealing block and the outer sealing block more stable and reliable, thereby extending the service life of the equipment. When it is necessary to dispense medicine into the cylinder, the driving member drives the bidirectional screw to rotate, causing the inner sealing block and the outer sealing block to move away from each other, thereby opening the drug dispensing port. At this time, the medicine can enter the cylinder through the drug dispensing port, mix with the mud, and promote solid-liquid separation. After the drug addition is completed, the driving member rotates in the opposite direction, driving the inner sealing block and the outer sealing block to move toward each other, closing the drug dispensing port, ensuring that the mud in the cylinder will not leak, and ensuring the normal operation and safety of the equipment.

[0015] Optionally, a side of the inner sealing block close to the outer sealing block is provided with an arc, and the outer sealing block cooperates with the inner sealing block.

[0016] By adopting the above technical solution, the inner sealing block is provided with an arc on the side close to the outer sealing block. The outer sealing block and the inner sealing block are arranged in coordination to ensure a close fit between the two, thereby improving the sealing performance of the medicine dispensing port and preventing mud leakage. At the same time, it helps to make the medicine flow along the arc at the top of the inner sealing block, thereby improving the dispersion uniformity of the medicine and ensuring the smooth progress of the medicine dispensing process.

[0017] Optionally, a water stop strip is provided on the outer periphery of the medicine dispensing port, the water stop strip is protruded on the inner side of the side wall of the cylinder, the inner sealing block is provided with a mounting groove, and the water stop strip is aligned with the mounting groove.

[0018] By adopting the above technical solution, the water stop strip on the outer periphery of the medicine outlet is aligned with the mounting groove on the inner sealing block, which can effectively prevent mud from leaking during the separation process and ensure the safety and reliability of the equipment operation.

[0019] Optionally, the medicine dispensing mechanism includes a medicine dispensing component, and the medicine dispensing component includes a medicine dispensing box and a driving member. The medicine dispensing box is slidably connected to the side wall of the cylinder, one end of the driving member is hinged to the medicine dispensing box, and the other end of the driving member is hinged to the outer sealing block. When the outer sealing block moves in the direction away from the medicine dispensing port, the driving member drives the medicine dispensing box to move toward the medicine dispensing port to dispense medicine to the medicine dispensing port. When the outer sealing block moves in the direction close to the medicine dispensing port, the driving member drives the medicine dispensing box to move away from the medicine dispensing port.

[0020] By adopting the above technical solution, the drug dispensing mechanism can realize automated control of the drug dispensing process. Specifically, when the outer sealing block moves in the direction away from the drug dispensing port, the driving member will drive the drug dispensing box to move in the direction close to the drug dispensing port, thereby accurately dispensing the drug into the cylinder. Conversely, when the outer sealing block moves in the direction close to the drug dispensing port, the driving member will move the drug dispensing box away from the drug dispensing port, reducing the risk of interference. This design not only improves the efficiency of drug dispensing, but also reduces the need for manual operation, improving the overall performance and reliability of the equipment.

[0021] Optionally, a plurality of drug delivery components are evenly distributed along the length direction of the cylinder.

[0022] By adopting this technical solution, the drug liquid distribution is more uniform and stable, effectively improving the dispersion of the drug in the slurry, thereby enhancing the efficiency and quality of solid-liquid separation. Furthermore, the configuration of multiple drug delivery components can increase drug delivery speed, adapt to the needs of different working conditions, and improve the working efficiency and application range of the equipment.

[0023] Optionally, the stirring mechanism includes a column, a height adjustment member, a connecting plate, a motor and a stirring assembly, the column is arranged on one side of the cylinder, the fixed end of the height adjustment member is arranged at the first end of the column, the second end of the column is connected to the supporting mechanism, the telescopic end of the height adjustment member is connected to the connecting plate, the motor is connected to the connecting plate, the output end of the motor can be transmitted and connected to the stirring assembly, and the stirring assembly is rotatably connected in the cylinder.

[0024] By adopting the above technical solution, the height of the driving motor can be adjusted through the height adjusting member, so that it can be moved down and connected to the stirring assembly to achieve stirring when the cylinder is in a vertical state. When the cylinder needs to be flipped to a horizontal state, the height adjusting member can be adjusted to disconnect the motor from the stirring assembly, so that the flipping of the cylinder can be achieved.

[0025] Optionally, a baffle is provided in the cylinder, the first end of the cylinder is open, the baffle is spaced apart from the first end of the cylinder, and a accommodating chamber is formed between the baffle and the bottom of the cylinder, the stirring assembly includes a rotating shaft, a stirring blade and an auger, the rotating shaft is rotatably connected to the baffle, the rotating shaft is used to be connected to the motor transmission, the stirring blade and the auger are both connected to the rotating shaft, the stirring blade is set away from the second end of the cylinder, the auger is set close to the second end of the cylinder, and the auger is used to push the separated solids out of the second outlet.

[0026] By adopting the above technical solution, the baffle design creates a holding chamber inside the cylinder for holding sewage and achieving solid-liquid separation within the chamber. When the rotating shaft is connected to the motor, the stirring blades agitate the sewage, optimizing the mixing effect of the liquid medicine and sewage and improving separation efficiency. After the sewage and liquid medicine fully react to achieve flocculation and sedimentation, the auger near the second end of the cylinder, driven by the motor, pushes the flocculated and separated solids to the second outlet for discharge, ensuring the effective removal of solid matter and avoiding clogging. The combined action of the stirring blades and the auger not only enhances the stirring effect of the mud and promotes the solid-liquid separation process, but also ensures the smooth discharge of the separated solids, improving the operating stability and reliability of the entire device.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a conversion mechanism, especially the coordinated action of the telescopic member, push block, transmission assembly, pulling member and supporting member, the cylinder can smoothly switch between the vertical state and the horizontal state, effectively solving the problem of high power and poor reliability required by the single pull rod drive mode, and improving the stability and safety of equipment operation; 2. The unique design of the drug dispensing mechanism, through the cooperation of the support frame, drive member, bidirectional screw, guide rod, inner sealing block and outer sealing block, can conveniently control the opening or closing of the drug dispensing port, thereby improving the convenience of operation.

[0036] The following is combined with Figure 1 -Attached Figure 7 The present application is further described in detail. In this embodiment, unless otherwise specified, the terms "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, and can be understood based on the specific circumstances.

Moreover, in the description of this embodiment, the terms "above", "below", "left", "right", and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. Unless otherwise specified, orientation words such as "inside" and "outside" used in this application refer to the outlines of the corresponding components themselves.

[0038] like Figure 1 As shown, an embodiment of the present application discloses a deep-sea drilling mud solid-liquid separation device (hereinafter referred to as "device"), which includes a supporting mechanism 1, a cylinder 2, a stirring mechanism 3, a drug dispensing mechanism 4, a collecting mechanism 5 and a conversion mechanism 6.

[0039] like Figure 1 and Figure 2 As shown, the setting of the support mechanism 1 ensures the stability and reliability of the entire device, avoids accidental movement or tilting during use, and improves the safety performance of the equipment. The specific structure of the support mechanism 1 is not limited. The cylinder 2 is mounted on the support mechanism 1, and the cylinder 2 is hinged to the support mechanism 1 so that the cylinder 2 can rotate around the hinge point between it and the support mechanism 1 to achieve flipping. The cylinder 2 is provided with an input port 21, a first outlet 22 and a second outlet 23, all of which can be selectively opened and closed. The input port 21 is used to input mud into the cylinder 2, the first outlet 22 is used to output the separated liquid, and the second outlet 23 is used to output the separated solid. The input port 21, the first outlet 22 and the second outlet 23 can all be provided with solenoid valves to control opening and closing. The stirring mechanism 3 is arranged in the cylinder 2, and the stirring mechanism 3 is used to stir the mud. The drug dispensing mechanism 4 is connected to the cylinder 2, and the drug dispensing mechanism 4 is used to add a flocculant or other liquid medicine into the cylinder 2, so that the mud can be separated into solid and liquid through the liquid medicine. The interior of the cylinder 2 is provided with a stirring mechanism 3 and a drug dispensing mechanism 4. After the drug dispensing mechanism 4 adds liquid medicine, the stirring mechanism 3 can fully mix the slurry, promoting the rapid sedimentation of solid particles in the slurry and improving the efficiency of solid-liquid separation. The collection mechanism 5 is provided on the support mechanism 1 and below the cylinder 2. The collection mechanism 5 can cooperate with the second outlet 23 to collect the separated solids, facilitating subsequent processing and cleaning, while also helping to maintain a clean and tidy on-site environment.

[0040] like Figure 1 and Figure 2As shown, the conversion mechanism 6 includes a telescopic member 61, a push block 62, a transmission assembly 63, a pull member 64, and a support member 65. The fixed end of the telescopic member 61 and the support member 65 are both fixedly mounted on the support mechanism 1, while the push block 62 is slidably connected to the support mechanism 1. The telescopic end of the telescopic member 61 is transmission-connected to one end of the transmission assembly 63, the other end of which is connected to the push block 62. The transmission assembly 63 is hinged to the first end of the pull member 64, the second end of which is hinged to the first end of the cylinder 2. When the telescopic member 61 drives the transmission assembly 63 to move, the pushing block 62 pushes the collecting mechanism 5 and the second end of the cylinder 2 in turn, so that the collecting mechanism 5 is offset to the side of the cylinder 2 away from the telescopic member 61; then, the pushing block 62 pushes the second end of the cylinder 2, and at the same time, the pulling member 64 pulls the first end of the cylinder 2, and the cylinder 2 rotates around the hinge point between it and the supporting mechanism 1, and the cylinder 2 is flipped, so that the first end of the cylinder 2 abuts the supporting member 65, and the pushing block 62 supports the second end of the cylinder 2, so that the length direction of the cylinder 2 is converted from a vertical state for separating mud to a horizontal state for inputting mud.

[0041] The device can achieve efficient solid-liquid separation of mud and has good operational flexibility and stability. The design of the conversion mechanism 6 allows the cylinder 2 to switch freely between the vertical state and the horizontal state. When mud needs to be input, the cylinder 2 can be adjusted to a horizontal position to facilitate the injection of mud; and in the working state, the cylinder 2 returns to a vertical position to ensure that the separation process proceeds smoothly. The telescopic member 61 can be a telescopic structure such as a cylinder, a hydraulic cylinder or an electric telescopic rod. The upper ends of the push block 62 and the support member 65 can be provided with a rounded transition, or even be provided with an arc-shaped upper end surface. The specific shape can be set according to actual needs, with the purpose of reducing interference with the turning of the cylinder 2.

[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, when it is necessary to convert the cylinder 2 from a vertical state to a horizontal state, the push block 62 can first push the collecting mechanism 5 to deflect to the side of the cylinder 2 away from the telescopic member 61, and then continue to push the second end of the cylinder 2, while the pulling member 64 pulls the first end of the cylinder 2, causing the cylinder 2 to rotate around the hinge point with the support mechanism 1. Ultimately, the first end of the cylinder 2 abuts against the supporting member 65, and the push block 62 supports the second end of the cylinder 2, making it in a horizontal state. This process not only ensures that the cylinder 2 completes the posture conversion smoothly, but also improves the safety and convenience of operation. When it is necessary to restore the cylinder 2 from a horizontal state to a vertical state, since there is a certain distance between the second end of the cylinder 2 and the push block 62, under the action of the pull member 64, the second end of the cylinder 2 can smoothly push the push block 62 to move, thereby cooperating with the telescopic member 61, providing sufficient power for the pull member 64, and realizing efficient and stable flipping of the cylinder 2.

[0043] like Figure 1 、 Figure 2 and Figure 4 As shown, optionally, the stirring mechanism 3 includes a column 31, a height adjustment member 32, a connecting plate 33, a motor 34, and a stirring assembly 35. The column 31 is arranged on one side of the cylinder 2, the fixed end of the height adjustment member 32 is arranged at the first end of the column 31, and the second end of the column 31 is connected to the support mechanism 1, so that the height of the stirring mechanism 3 can be adjusted. The telescopic end of the height adjustment member 32 is connected to the connecting plate 33, and the motor 34 is connected to the connecting plate 33. The output end of the motor 34 can be connected to the stirring assembly 35, and the stirring assembly 35 is rotatably connected to the cylinder 2. The height adjustment member 32 makes the height of the driving motor 34 adjustable, so that it can move downward when the cylinder 2 is in a vertical position to connect with the stirring assembly 35 to achieve stirring; when the cylinder 2 needs to be flipped to a horizontal position, the height adjustment member 32 can be adjusted to disconnect the motor 34 from the stirring assembly 35, so that the cylinder 2 can be flipped. The height adjustment member 32 can be a telescopic structure such as a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0044] like Figure 1 、 Figure 2 and Figure 4 As shown, optionally, a baffle 26 is provided within the cylinder 2. The first end of the cylinder 2 is open, and the baffle 26 is spaced apart from the first end of the cylinder 2, forming a receiving chamber between the baffle 26 and the bottom of the cylinder 2. The stirring assembly 35 includes a rotating shaft 351, a stirring blade 352, and an auger 353. The rotating shaft 351 is rotatably connected to the baffle 26, and the rotating shaft 351 is used for transmission connection with the motor 34. The stirring blade 352 and the auger 353 are both connected to the rotating shaft 351. The stirring blade 352 is located away from the second end of the cylinder 2 and is used to stir the sewage. The auger 353 is located near the second end of the cylinder 2 and is used to push the separated solids out of the second outlet 23. The design of the baffle 26 forms a receiving chamber within the cylinder 2, which is used to hold the sewage and achieve solid-liquid separation within the receiving chamber. When the rotating shaft 351 is connected to the motor 34, the stirring blade 352 stirs the sewage, optimizing the mixing effect of the liquid medicine and the sewage, and improving the separation efficiency. After the sewage and the liquid chemical have fully reacted to achieve flocculation and sedimentation, the auger 353 near the second end of the cylinder 2, driven by the motor 34, pushes the flocculated and separated solids to the second outlet 23 for discharge, ensuring effective removal of solid matter and avoiding clogging. The combined action of the stirring blades 352 and the auger 353 not only enhances the agitation of the slurry and promotes the solid-liquid separation process, but also ensures the smooth discharge of the separated solids, improving the operational stability and reliability of the entire device.

[0045] Optionally, the stirring mechanism 3 includes a limit block, which is arranged at the output end of the motor 34. The end of the rotating shaft 351 is provided with a limit groove. The limit block can be engaged with the limit groove so that the motor 34 can drive the rotating shaft 351 to rotate, thereby realizing effective stirring of the mud in the cylinder 2.

[0046] like Figure 1 、 Figure 2 and Figure 4 As shown, optionally, the transmission assembly 63 includes a first rack 631, a gear 632, and a second rack 633. The first rack 631 and the second rack 633 are both slidably connected to the support mechanism 1, and the gear 632 is rotationally connected to the support mechanism 1. The first rack 631 and the second rack 633 are respectively arranged on opposite sides of the gear 632. The first rack 631 and the second rack 633 are both engaged with the gear 632, and the movement directions of the first rack 631 and the second rack 633 are opposite. The telescopic end of the telescopic member 61 is connected to the end of the first rack 631 away from the collecting mechanism 5, and the other end of the first rack 631 is connected to the pushing block 62. The second rack 633 is hinged to the first end of the pulling member 64, which can achieve precise control of the movement of the pushing block 62 and the pulling member 64.

[0047] When the position of the cylinder 2 needs to be adjusted to a horizontal state, the telescopic end of the telescopic member 61 pushes the first rack 631 toward the collection mechanism 5. The telescopic action of the telescopic member 61 is transmitted to the push block 62 through the first rack 631, allowing the push block 62 to slide smoothly on the support mechanism 1 and push the collection mechanism 5 and the second end of the cylinder 2 in turn, causing the cylinder 2 to tilt smoothly. Since the first rack 631 is engaged with the gear 632, the movement of the first rack 631 will drive the gear 632 to rotate. As the gear 632 rotates, the second rack 633 will move away from the collection mechanism 5 under the action of the gear 632. The second rack 633 pulls the first end of the pulling member 64 through a hinged relationship, and the second end of the pulling member 64 correspondingly pulls the first end of the cylinder 2, causing the cylinder 2 to rotate about its hinge point with the support mechanism 1. The meshing action of the second rack 633 and the gear 632 ensures the effective linkage of the pulling member 64, thereby pulling and flipping the first end of the cylinder 2, and ultimately turning the cylinder 2 from a vertical position to a horizontal position, facilitating the input and processing of mud. During this process, the design of the transmission assembly 63 ensures the coordinated operation of various components, improving the operational stability and reliability of the device.

[0048] like Figure 1 、 Figure 2 and Figure 4As shown, the push block 62 optionally includes a first push portion 621 and a second push portion 622. The first push portion 621 is located on the side of the second push portion 622 near the collection mechanism 5. The top of the first push portion 621 is lower than the lowest point of the cylinder 2 in its vertical position, while the top of the second push portion 622 is higher than the lowest point of the cylinder 2 in its vertical position. The first push portion 621 and the second push portion 622 are located at different heights, allowing the push block 62 to push the collection mechanism 5 and the cylinder 2 at different stages. This design ensures more precise and reliable operation during the transition process. The top of the first push portion 621 is lower than the lowest point of the cylinder 2, preventing collision or interference with the cylinder 2 during the pushing process, ensuring the safety and stability of the device. The top of the second push portion 622 is higher than the lowest point of the cylinder 2. When the cylinder 2 needs to be pushed, it can effectively apply thrust, allowing the cylinder 2 to smoothly rotate around the hinge point, completing a rapid transition from vertical to horizontal, and improving work efficiency.

[0049] Optionally, two supporting members 65 are provided, and the two supporting members 65 are spaced apart. When the cylinder 2 is in a vertical state, the push block 62 is clamped between the two supporting members 65. The provision of the two supporting members 65 can effectively ensure the stability and reliability of the cylinder 2 in a vertical state, and avoid the cylinder 2 from tilting or being damaged due to uneven force on a single supporting member 65. At the same time, when the cylinder 2 is in a vertical state, the push block 62 is clamped between the two supporting members 65, which can ensure that the push block 62 is accurately positioned during the conversion process, thereby improving the overall operating accuracy and safety of the device. The specific structure of the supporting member 65 is set as needed, and can achieve a supporting effect without interfering with the cylinder 2.

[0050] like Figure 1 、 Figure 2 and Figure 4 As shown, optionally, two pulling members 64 are provided, and the two pulling members 64 are symmetrically arranged on both sides of the cylinder 2. The conversion mechanism 6 includes a support member, one end of the support member is hinged to the second rack 633, and the other end of the support member is hinged to the first ends of the two pulling members 64. By providing two symmetrically arranged pulling members 64 and support members, the cylinder 2 is made more stable and reliable during the conversion process, the pulling force is evenly distributed, and the tilting or instability caused by unilateral force is avoided. The design of the support member further enhances the stability of the structure. By hingedly connecting the second rack 633 and the pulling member 64 at both ends, it can effectively transmit and distribute power, ensuring that the entire conversion process is smooth and unobstructed. This design not only improves the working efficiency of the equipment, but also extends its service life and reduces the risk of wear and failure caused by imbalance.

[0051] like Figure 1 、 Figure 4 and Figure 5As shown, optionally, a drug dispensing port 24 is provided on one side of the barrel 2, and the drug dispensing mechanism 4 cooperates with the drug dispensing port 24. The drug dispensing mechanism 4 includes a support frame 41, a driving member 42, a bidirectional screw 43, a guide rod 44, an inner sealing block 45 and an outer sealing block 46. One end of the support frame 41 is connected to the barrel 2, and the other end of the support frame 41 is connected to the driving member 42. The output end of the driving member 42 is transmission-connected to the bidirectional screw 43, and the inner sealing block 45 and the outer sealing block 46 are both screwed to the bidirectional screw 43. The inner sealing block 45 is arranged inside the barrel 2, and the outer sealing block 46 is arranged outside the barrel 2. A guide rod 44 is provided on the side wall of the barrel 2. The bidirectional screw 43 is parallel to the guide rod 44 and extends in a direction perpendicular to the length of the barrel 2. The inner sealing block 45 and the outer sealing block 46 are both slidably connected to the guide rod 44. The driving member 42 drives the bidirectional screw 43 to rotate, and can synchronously drive the inner sealing block 45 and the outer sealing block 46 to move toward or away from each other. The inner and outer sealing blocks 45, 46 move toward each other to seal the drug delivery port 24. When the inner and outer sealing blocks 45, 46 move away from each other, the drug delivery port 24 is opened, allowing drug delivery through the drug delivery port 24. This automatically opens and closes the drug delivery port 24, improving the automation level of the device. In this embodiment, the bidirectional lead screw 43 is a left-hand and right-hand lead screw with oppositely rotating threads at both ends, allowing the inner and outer sealing blocks 45, 46 to move toward or away from each other when the bidirectional lead screw 43 rotates. The drive member 42 may be a motor structure.

[0052] like Figure 5 、 Figure 6 and Figure 7 As shown, the design of the inner sealing block 45 and the outer sealing block 46 ensures a tight seal of the drug dispensing port 24, prevents drug leakage, and ensures the safety and sanitation of the working environment. At the same time, the coordinated use of the bidirectional screw 43 and the guide rod 44 makes the movement of the inner sealing block 45 and the outer sealing block 46 more stable and reliable, extending the service life of the equipment. When it is necessary to dispense drugs into the barrel 2, the driving member 42 drives the bidirectional screw 43 to rotate, causing the inner sealing block 45 and the outer sealing block 46 to move away from each other, thereby opening the drug dispensing port 24. At this time, the drug can enter the barrel 2 through the drug dispensing port 24, mix with the mud, and promote solid-liquid separation. After the drug is added, the driving member 42 rotates in the opposite direction, driving the inner sealing block 45 and the outer sealing block 46 to move toward each other, closing the drug dispensing port 24, ensuring that the mud in the barrel 2 will not leak, and ensuring the normal operation and safety of the equipment. The drug dispensing mechanism 4 includes necessary sealing structures to ensure that when the barrel 2 is in a vertical state, the internal sewage will not leak.

[0053] Optionally, the drug dispensing mechanism 4 includes a drug dispensing assembly 47. The drug dispensing assembly 47 includes a drug dispensing box 471 and a driving member 472. The drug dispensing box 471 is slidably connected to the side wall of the cylinder 2, one end of the driving member 472 is hinged to the drug dispensing box 471, and the other end of the driving member 472 is hinged to the outer sealing block 46. When the outer sealing block 46 moves in the direction away from the drug dispensing port 24, the driving member 472 drives the drug dispensing box 471 to move in the direction close to the drug dispensing port 24, so as to dispense drugs to the drug dispensing port 24. When the outer sealing block 46 moves in the direction close to the drug dispensing port 24, the driving member 472 drives the drug dispensing box 471 to move in the direction away from the drug dispensing port 24, thereby reducing the risk of interference. This design not only improves the efficiency of drug dispensing, but also reduces the need for manual operation, thereby improving the overall performance and reliability of the equipment. It is understandable that the drug dispensing operation can also be completed manually.

[0054] like Figure 5 、 Figure 6 and Figure 7 As shown, several drug delivery assemblies 47 are optionally evenly distributed along the length of the barrel 2, ensuring uniform and stable distribution of the drug solution, effectively improving the dispersion of the drug in the slurry, and thereby enhancing the efficiency and quality of solid-liquid separation. Furthermore, the provision of multiple drug delivery assemblies 47 can increase drug delivery speed, adapt to the needs of different working conditions, and improve the operating efficiency and applicability of the equipment.

[0055] Optionally, the inner sealing block 45 has a curved edge on one side near the outer sealing block 46 to protrude from the drug dispensing port 24. The outer sealing block 46 and the inner sealing block 45 cooperate to form a tight fit, thereby improving the sealing performance of the drug dispensing port 24 and preventing slurry leakage. This also helps the drug solution flow along the curved edge of the inner sealing block 45 during drug dispensing, improving the uniformity of drug dispensing and ensuring a smooth drug dispensing process.

[0056] like Figure 5 、 Figure 6 and Figure 7 As shown, optionally, a water stop strip 25 is provided on the outer periphery of the medicine outlet 24, and the water stop strip 25 is protruded on the inner side of the side wall of the cylinder 2. The inner sealing block 45 is provided with a mounting groove 451. The water stop strip 25 is aligned with the mounting groove 451, which can effectively prevent the mud from leaking during the separation process and ensure the safety and reliability of the equipment operation.

[0057] like Figure 1 As shown, the collection mechanism 5 optionally includes a collection box and universal wheels. The bottom of the collection box is provided with a plurality of universal wheels, which can be easily moved and adjusted, thereby improving the flexibility and ease of operation of the device. At the same time, the design of the universal wheels makes it easier to push the collection box after carrying the separated solids.

[0058] It can be understood that the device also includes necessary structures for connection, support, driving, positioning, limiting, sealing and control functions so that the device can operate normally; the parameters such as the shape, size, material and setting quantity of each part of the device can be determined as needed as long as the corresponding functions can be achieved.

[0059] The implementation principle of a deep-sea drilling mud solid-liquid separation device in an embodiment of the present application is as follows: a stirring mechanism 3 and a drug-feeding mechanism 4 are provided inside the cylinder 2. After the drug-feeding mechanism 4 adds drugs, the stirring mechanism 3 can fully mix the mud, promote the rapid precipitation of solid particles in the mud, and improve the solid-liquid separation efficiency; the design of the conversion mechanism 6 enables the cylinder 2 to reliably switch between the vertical state and the horizontal state. When mud needs to be input, the cylinder 2 can be adjusted to a horizontal position to facilitate the injection of mud; and in the working state, the cylinder 2 returns to the vertical position to ensure that the separation process proceeds smoothly.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
