Description

Technical Field

[0001] This utility model relates to the field of cyclone desanding and desilting equipment, and more specifically to an integrated hydraulic mechanical device for desanding and desilting. Background Technology

[0002] Existing hydrocyclones for desanding and desilting have many limitations in practical applications. For example, traditional static hydrocyclones require high inlet pressure, placing stringent demands on the head of the supply pump; they also have poor adaptability to changes in drilling fluid viscosity and properties. When the drilling fluid viscosity is high, internal friction resistance and pressure loss increase significantly, easily leading to leaks and screen clogging, resulting in low separation efficiency. Furthermore, due to the pressure characteristics of the supply pump, traditional hydrocyclones can typically only separate solid particles of a specific size, with a limited range of processing capacity, making it difficult to meet diverse needs under complex operating conditions.

[0003] To address the aforementioned issues, the Beijing Institute of Exploration Engineering applied for a utility model patent (patent number: CN216125867U) on October 25, 2021, and was granted authorization on March 25, 2022. This patent proposes a vertical composite dynamic hydrocyclone separator. By introducing a rotating mechanism, the traditional fixed connection between the cylindrical body and the conical tube is changed to a rotating connection, enabling the conical tube to rotate. This innovative design converts kinetic energy into pressure energy, reducing the impact of pressure fluctuation losses and improving separation characteristics and adaptability to variable flow conditions. This device not only significantly improves separation effect and efficiency but also operates under no-pressure or low-pressure conditions, thereby reducing the requirements for the supply pump.

[0004] However, with the continuous development of technology and the increasing complexity of application scenarios, existing patented technologies still have some shortcomings in practical applications, especially in the design of drive devices, where there is still room for further optimization. For example, the stability and adaptability of existing drive devices in dealing with variable flow conditions still need to be improved; the durability and reliability of drive devices under complex conditions also have room for improvement; in addition, existing technologies have limited capacity to handle drilling fluids of different viscosities and densities, making it difficult to meet the needs of diverse application scenarios.

[0005] Therefore, how to develop a more efficient, stable, and adaptable integrated sand and mud removal device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides an integrated hydraulic mechanical device for sand and mud removal, which aims to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An integrated hydraulic mechanical device for sand and sludge removal includes:

[0009] The frame has a hydrocyclone separator body mounted on one side. The upper part of the hydrocyclone separator body is provided with a hydraulic feed inlet. The middle part of the hydrocyclone separator body has a driven pulley. The rotation of the driven pulley can drive the lower conical tube to rotate.

[0010] An adjustable mounting plate is slidably connected to the frame and fastened by a bolt assembly. The adjustable mounting plate has an adjusting screw on the side away from the cyclone separator body, and the adjusting screw is connected to the end of the frame by an adjusting nut.

[0011] A drive motor is fixed to the bottom surface of the adjustable mounting plate, and its power output axis passes through the adjustable mounting plate axially.

[0012] An active pulley is located above the adjustable mounting plate and is securely connected to the power output shaft of the drive motor.

[0013] A drive belt is fitted onto the driving pulley and the driven pulley.

[0014] Through the above technical solution, this utility model combines hydrocyclone separation with mechanical drive via belt transmission. Utilizing the rotation of the conical tube in the hydrocyclone separator body, it further improves the separation effect and adaptability to variable flow conditions, while reducing the requirement for feed pressure, allowing for pressureless or low-pressure operation and reducing reliance on the liquid supply pump. The newly added adjustable mounting plate and adjusting screw design allow for flexible and convenient adjustment of the drive belt tension, thereby ensuring the stability and reliability of the transmission system and effectively extending the equipment's service life.

[0015] Preferably, in the aforementioned integrated hydraulic mechanical device for sand and mud removal, corresponding grooves are provided on both sides of the frame and the adjustable mounting plate, and the bolt assembly passes through the grooves. This structure facilitates the sliding adjustment and fastening of the adjustable mounting plate, allowing the device to flexibly adjust the positions of the driving pulley and driven pulley as needed to adapt to different transmission requirements and installation conditions.

[0016] Preferably, in the aforementioned integrated hydraulic mechanical device for sand and mud removal, the power output shaft of the drive motor is connected to the drive pulley via a tapered sleeve. The tapered sleeve has a through hole in its center for insertion into the power output shaft of the drive motor. The outer wall of the tapered sleeve engages with the center hole of the drive pulley via a tapered inclined surface. Multiple adjusting grooves are evenly spaced axially on the side wall of the tapered sleeve. The tapered sleeve and the drive pulley are fastened together with bolts. This structure ensures a tight connection between the drive pulley and the power output shaft of the drive motor, resulting in efficient and stable power transmission. Furthermore, the design of the adjusting grooves and tapered inclined surface facilitates installation and adjustment.

[0017] Preferably, in the aforementioned integrated desanding and sludge removal hydraulic mechanical coordinating device, the number of adjusting grooves is three, causing the cone sleeve to form a three-lobed claw structure. The cone sleeve with the three-lobed claw structure is connected to the drive pulley, making the connection more secure and the force more even, which can effectively improve the stability and reliability of the transmission, while also facilitating disassembly and installation.

[0018] Preferably, in the aforementioned integrated desanding and sludge removal hydraulic-mechanical coordinated device, the driven pulley and the central cylinder of the cyclone separator body are rotatably connected by a pair of deep groove ball bearings. The deep groove ball bearings can withstand radial loads and a certain axial load, ensuring smooth rotation of the driven pulley and the tapered tube, reducing friction loss, and improving the operating efficiency and service life of the device.

[0019] Preferably, in the aforementioned integrated hydraulic mechanical device for sand and mud removal, the bottom of the conical tube is connected to the frame via an auxiliary support mechanism. The auxiliary support mechanism includes a base and a rotating seat. The base is fixed to the frame, and the rotating seat is rotatably connected to the inner side of the base via a bearing. The central hole of the rotating seat is fixed to the bottom of the conical tube. This auxiliary support structure effectively prevents the conical tube from shifting during rotation, provides stable support, ensures the normal operation of the conical tube, and enhances the overall stability of the device.

[0020] Preferably, in the aforementioned integrated hydraulic mechanical device for sand and mud removal, a cover is also fixed on the frame, covering the drive pulley. The cover effectively prevents external debris from entering the transmission components between the drive pulley and the transmission belt, avoiding impact on transmission efficiency and damage to parts. It also provides safety protection, preventing accidental contact with transmission components and improving equipment safety.

[0021] Preferably, in the aforementioned integrated hydraulic mechanical device for sand and mud removal, the top surface of the frame is designed as a two-stage stepped structure. The cyclone separator body is mounted on the upper step of the stepped structure, and the adjustable mounting plate is connected to the lower step of the stepped structure, so that the driving pulley and the driven pulley are located on the same horizontal plane. This design helps to ensure the correct installation and tension of the transmission belt, ensuring the smoothness and reliability of the transmission.

[0022] Preferably, in the aforementioned integrated hydraulic mechanical device for sand and mud removal, a vibrating screen mechanism is connected to the bottom of the frame, and the bottom outlet of the conical tube is connected to the inlet of the vibrating screen mechanism. This achieves an organic combination of cyclone separation and vibrating screening, allowing the solid-liquid mixture after cyclone separation to be directly introduced into the vibrating screen mechanism for further screening, improving separation efficiency and solid particle recovery rate, and enabling better control of the particle size range to meet different process requirements.

[0023] Preferably, in the aforementioned integrated hydraulic mechanical device for sand and mud removal, a buffer diversion mechanism is installed between the bottom of the frame and the vibrating screen mechanism. The solid-liquid mixture flowing out from the bottom of the conical tube enters the buffer diversion mechanism before entering the vibrating screen mechanism. The buffer diversion mechanism reduces the impact of the solid-liquid mixture on the vibrating screen mechanism, improving the stability and service life of the equipment. Through the buffering and diversion effect of the diversion buffer cone, liquids with different solid content can be classified and processed, improving the screening effect and efficiency.

[0024] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an integrated hydraulic mechanical device for sand and mud removal, which has the following beneficial effects:

[0025] 1. High-efficiency and stable transmission system: Through a carefully designed belt drive mechanism, including adjustable drive pulleys and driven pulleys, the transmission system can operate stably and reliably, and the belt tension can be flexibly adjusted according to actual needs, thereby ensuring effective power transmission and improving the overall performance and operating efficiency of the equipment.

[0026] 2. Flexible and adjustable installation structure: The design of the adjustable mounting plate and adjusting screw allows the device to flexibly adapt to different installation and usage scenarios, facilitating on-site debugging and maintenance, and enhancing the versatility and practicality of the equipment.

[0027] 3. Reliable and durable connection method: The connection structure between the tapered sleeve and the drive pulley adopts a tapered inclined surface fit and bolt fastening method to form a three-lobed claw structure, which not only ensures the firmness and reliability of the connection, but also facilitates installation and disassembly, thereby improving the service life and maintenance convenience of the equipment.

[0028] 4. Smooth and stable rotation support: The deep groove ball bearing connection between the driven pulley and the hydrocyclone separator body, as well as the auxiliary support mechanism at the bottom of the tapered tube, together provide stable support for the rotating parts of the hydrocyclone separator, reducing vibration and wear during rotation, enabling the equipment to operate smoothly and stably, and improving the separation effect and work efficiency.

[0029] 5. Safety and aesthetics: The design of the enclosure not only effectively prevents external debris from interfering with the transmission components and improves the safety of the equipment, but also makes the entire device neater and more aesthetically pleasing, facilitating on-site management and operation.

[0030] 6. Optimized and reasonable structural layout: The double-step structure design of the frame allows the driving pulley and the driven pulley to be located on the same horizontal plane, ensuring the correct installation and tension of the transmission belt. It also contributes to the structural stability and compactness of the entire device, improving space utilization and equipment integration.

[0031] 7. Excellent screening effect and high processing capacity: By connecting a vibrating screen mechanism to the bottom of the frame and setting a buffer diversion mechanism between the frame and the vibrating screen mechanism, an effective combination of cyclone separation and vibrating screening is achieved. This design not only improves separation efficiency and solid particle recovery rate, but also allows for the classification and processing of liquids with different solid content, meeting the process requirements of different particle size ranges. This significantly enhances the screening effect and processing capacity of the entire device, giving it broader application prospects and higher production efficiency in the field of solid-liquid separation.

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0061] Example 1:

[0062] See appendix Figure 1 To be continued Figure 5 This utility model discloses an integrated hydraulic mechanical device for sand and mud removal, comprising:

[0063] The frame 1 has a hydrocyclone separator body 6 installed on one side. The upper part of the hydrocyclone separator body 6 is provided with a hydraulic feed inlet 61. The middle part of the hydrocyclone separator body 6 has a driven pulley 62. The rotation of the driven pulley 62 can drive the lower conical tube 63 to rotate.

[0064] Adjustable mounting plate 2 is slidably connected to frame 1 and fastened by bolt assembly 21. Adjustable mounting plate 2 has an adjusting screw 22 on the side away from the hydrocyclone separator body 6. The adjusting screw 22 is connected to the end of frame 1 by adjusting nut 23.

[0065] Drive motor 3 is fixed to the bottom surface of adjustable mounting plate 2, and its power output axis passes through adjustable mounting plate 2 axially.

[0066] The active pulley 4 is located above the adjustable mounting plate 2 and is securely connected to the power output shaft of the drive motor 3.

[0067] The transmission belt 5 is mounted on the driving pulley 4 and the driven pulley 62.

[0068] See appendix Figure 3 The frame 1 and the adjustable mounting plate 2 are provided with corresponding grooves 11 on both sides, and bolt assemblies 21 are inserted in the grooves 11.

[0069] See appendix Figure 4and attached Figure 5 The power output shaft of the drive motor 3 is connected to the drive pulley 4 through the tapered sleeve 41. The tapered sleeve 41 has a through hole 411 in the middle for insertion into the power output shaft of the drive motor 3. The outer wall of the tapered sleeve 41 and the center hole of the drive pulley 4 are fitted by a tapered inclined surface 412. Multiple adjusting grooves 413 are evenly provided axially on the side wall of the tapered sleeve 41. The tapered sleeve 41 and the drive pulley 4 are fastened together by bolts 42.

[0070] To further optimize the above technical solution, the number of adjustment grooves 413 is three, so that the cone sleeve 41 forms a three-lobed claw structure.

[0071] See appendix Figure 6 and attached Figure 7 The driven pulley 62 is rotatably connected to the middle cylinder of the cyclone separator body 6 by a pair of deep groove ball bearings 64.

[0072] See appendix Figure 8 and attached Figure 9 The bottom of the tapered tube 63 is connected to the frame 1 through an auxiliary support mechanism 7. The auxiliary support mechanism 7 includes a base 71 and a rotating seat 72. The base 71 is fixed on the frame 1, and the rotating seat 72 is rotatably connected to the inside of the base 71 through a bearing 73. The center hole of the rotating seat 72 is fixed to the bottom of the tapered tube 63.

[0073] To further optimize the above technical solution, a cover 12 is also fixed on the frame 1, which covers the drive pulley 4.

[0074] See appendix Figure 2 The top surface of the frame 1 is configured as a double-stage stepped structure 13. The cyclone separator body 6 is installed on the upper step 131 of the stepped structure 13, and the adjustable mounting plate 2 is connected to the lower step 132 of the stepped structure 13, so that the driving pulley 4 and the driven pulley 62 are located on the same horizontal plane.

[0075] Example 2:

[0076] See appendix Figure 10 The bottom of the frame 1 is connected to the vibrating screen mechanism 8, and the bottom outlet of the tapered tube 63 is connected to the inlet of the vibrating screen mechanism 8.

[0077] This design allows the solid-liquid mixture, after initial separation by the hydrocyclone separator, to directly enter the vibrating screen mechanism 8 for further screening. The vibrating screen mechanism 8 effectively separates solid particles from the liquid, improving separation efficiency and solid particle recovery rate. Through the screening action of the vibrating screen mechanism 8, the particle size range of solid particles can be better controlled to meet different process requirements.

[0078] Example 3:

[0079] See appendix Figure 10 A buffer diversion mechanism 9 is installed between the bottom of the frame 1 and the vibrating screen mechanism 8. The solid-liquid mixture flowing out from the bottom of the conical tube 63 enters the buffer diversion mechanism 9 and then enters the vibrating screen mechanism 8.

[0080] In this embodiment, the buffer diversion mechanism 9 includes a buffer housing 91, which is fixedly connected to the bottom of the frame 1. The top opening of the buffer housing 91 is connected to the bottom outlet of the tapered tube 63. The side wall of the buffer housing 91 is a tapered structure 911 that is wider at the top and narrower at the bottom. The middle of the inner bottom surface of the buffer housing 91 has an upwardly protruding diversion buffer cone 92. The top of the diversion buffer cone 92 corresponds to the bottom outlet of the tapered tube 63. The bottom surface of the buffer housing 91 has multiple downwardly extending multi-solid phase diversion tubes 93 around the diversion buffer cone 92. The multi-solid phase diversion tubes 93 are connected to the inlet of the vibrating screen mechanism 8 after being gathered together. The upper part of the side wall of the buffer housing 91 has multiple small solid phase diversion tubes 94. The small solid phase diversion tubes 94 extend downward and are connected to the inlet of the vibrating screen mechanism 8.

[0081] To further optimize the above technical solution, the downward extension of the less solid phase diversion pipe 94 forms a spiral pipe 941.

[0082] To further optimize the above technical solution, the diversion buffer cone 92 includes a frustum base 921 and a cone head 922 that is elastically connected to the top surface of the frustum base 921.

[0083] The material entering the buffer housing 91 is buffered by the diversion buffer cone 92. Then, the liquid with multiple solid phases flows into the vibrating screen mechanism 8 through the multi-solid phase diversion pipe 93, and the liquid with fewer solid phases flows into the vibrating screen mechanism 8 through the fewer solid phase diversion pipe 94. The diversion method makes the screening effect better.

[0084] In this embodiment, the buffer diversion mechanism 9 can effectively reduce the impact of the solid-liquid mixture on the vibrating screen mechanism 8, thereby improving the stability and service life of the equipment.

[0085] The buffering and diversion function of the diversion buffer cone 92 enables the classification and processing of liquids with different solid phase contents, improving screening effect and efficiency. The design of the multi-solid phase diversion pipe 93 and the low-solid phase diversion pipe 94 allows liquids with different solid phase contents to enter different areas of the vibrating screen mechanism, improving screening accuracy and processing efficiency. The spiral pipe 941 formed by the downward extension of the low-solid phase diversion pipe 94 further promotes the sedimentation and separation of solid particles, improving the separation effect.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
