Description

Technical Field

[0001] This utility model relates to the field of petroleum production technology, specifically to an inclined plate sedimentation and sand removal device. Background Technology

[0002] In oil development, gravel fracturing and fluid volume fracturing are used for reservoir stimulation. The gas and fluid produced at the wellhead of a normal production well contain a large amount of sand, which affects the normal production and safe and stable operation of surface process facilities. Research and practice have shown that sand particles can cause significant erosion to surface engineering equipment and pipelines, especially to throttling devices and elbows, which can lead to wear, perforation and failure of pipelines and equipment, resulting in safety risks.

[0003] A search revealed that patent application number CN202310936439.4 discloses an integrated device and method for removing sand by a built-in inclined plate. Although the device achieves efficient sand removal by setting up a coarse sand settling zone, a fine sand settling zone, and a settling inclined plate, it relies solely on gravity to make the coarse sand flow along the inclined plate and lacks a mechanism to actively adjust the angle of the inclined plate. When processing sand-containing gases or liquids with different flow rates and concentrations, it cannot adjust the state of the inclined plate in time to achieve the best separation effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an inclined plate sedimentation enhanced sand remover, which solves the problems mentioned in the background technology.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] An inclined plate sedimentation enhanced sand remover includes a body, and a discharge hopper is connected to the bottom of the body via a collection hopper.

[0007] The bottom of the machine body is supported by a second bracket. A first bracket is installed inside the machine body. An inclined plate is installed inside the machine body via the first bracket. A deflection mechanism is provided on the inclined plate. The inclined plate deflects inside the machine body through the deflection mechanism and the transmission mechanism. A filter box is mounted above the inclined plate. One end of the filter box is connected to an outlet pipe, and the end of the outlet pipe away from the filter box passes through the machine body. An inlet pipe is provided on the machine body at the inclined plate.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the bottom end of the inclined plate is rotatably mounted on the first bracket.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The rotatable installation of the inclined plate at its bottom provides a basis for its deflection within the machine body, allowing it to flexibly change angle under the drive of the transmission mechanism. This not only facilitates control over the sliding direction and speed of sand and gravel on the inclined plate, enabling automatic sand removal, but also allows for adjustment of the inclined plate angle at any time according to different working conditions and liquid sand content, optimizing sedimentation efficiency and enhancing the adaptability of the equipment.

[0012] Furthermore, the first bracket is provided with a support beam, and the filter box is supported on the first bracket by the support beam.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The support beam provides a stable support structure for the filter box, ensuring its stability during equipment operation and preventing displacement or shaking caused by liquid flow impact, which could affect filtration efficiency. At the same time, this installation method makes filter box disassembly and installation more convenient, facilitating regular filter element replacement by staff, maintaining equipment filtration performance, and reducing maintenance difficulty and time costs.

[0015] Furthermore, a filter element is placed inside the filter box, and a through hole is provided on the top of the filter box.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The filter cartridge design enables secondary fine filtration of the liquid after initial sedimentation by the inclined plate, effectively trapping residual fine sand particles and impurities, significantly improving the liquid's cleanliness. The through-holes on the filter box provide channels for the liquid to enter the filter cartridge; a well-designed layout ensures uniform liquid flow, maximizing the filter's filtration efficiency and quality.

[0018] Furthermore, the transmission mechanism includes a lead screw and a guide rod. A drive wheel is installed at one end of the lead screw located on the outside of the machine body, and the lead screw is connected to an external power device through the drive wheel.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The combination of the lead screw, guide rod, and drive wheel forms a stable and reliable transmission system. The lead screw converts the rotational motion of the external power equipment into linear motion, precisely controlling the deflection angle of the inclined plane. The guide rod acts as a guide, ensuring that the lead screw does not deviate during transmission, making the adjustment of the inclined plane angle more precise and stable. The connection between the drive wheel and the external power equipment facilitates power transmission and control. Operators can flexibly turn the power equipment on or off according to actual needs, realizing remote or automated adjustment of the inclined plane angle.

[0021] Furthermore, a connecting plate is rotatably mounted on the top of the inclined plate, and an upper connecting plate is mounted on the top of the connecting plate. The upper connecting plate meshes with the lead screw of the transmission mechanism for transmission, and the upper position of the inclined plate is adjusted by the cooperation between the lead screw and the upper connecting plate.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The meshing transmission design of the connecting plate, upper connecting plate, and lead screw constitutes the key transmission link for adjusting the swashplate angle. Through the meshing of the lead screw and upper connecting plate, the linear motion of the lead screw can be accurately transmitted to the swashplate, enabling fine adjustment of the swashplate angle. This transmission method not only has high transmission efficiency but also a compact structure, occupying little space. Furthermore, it can withstand various forces during the swashplate's deflection process, ensuring stable operation of the swashplate at different angles and improving the overall reliability of the equipment.

[0024] Furthermore, the connecting plate has sliding grooves on both sides, and the upper connecting plate has sliders at both ends. The upper connecting plate is movably connected to the sliding grooves of the connecting plate through the sliders.

[0025] The beneficial effects of adopting the above-mentioned further solutions are:

[0026] The movable connection structure between the groove and the slider provides smooth guidance and constraint for the relative movement between the upper connecting plate and the connecting plate. During the adjustment of the inclined plate angle, the upper connecting plate slides within the groove of the connecting plate via the slider, effectively avoiding jamming caused by poor movement and ensuring the flexibility and continuity of the inclined plate angle adjustment. Simultaneously, this structural design also disperses the force between the upper connecting plate and the connecting plate, reducing component wear, extending equipment lifespan, and improving equipment operational stability.

[0027] This utility model provides an inclined plate sedimentation enhanced sand remover. It has the following beneficial effects:

[0028] The inclined plate, designed based on the "shallow pool theory," greatly increases the sedimentation area and shortens the settling distance of sand and gravel particles. When sand-containing liquid enters the machine, sand and gravel impurities can quickly settle to the surface of the inclined plate under the action of gravity. Compared with the traditional single-container sedimentation method, this significantly improves the solid-liquid separation efficiency and can quickly separate a large amount of sand and gravel impurities.

[0029] The inclined plate's angle can be adjusted via a deflection mechanism and a transmission mechanism. When an external power source drives the drive wheel to rotate, causing the drive screw to rotate, the upper connecting plate meshing with it deflects the inclined plate. This allows for flexible control of the sliding speed and direction of sand and gravel on the inclined plate, promoting the automatic sliding and discharge of deposited sand and gravel. This eliminates the need for frequent manual cleaning of accumulated sand on the inclined plate, reducing labor intensity and improving the automation and continuity of equipment operation. The inclined plate angle can be adjusted according to actual working conditions. Whether processing liquids with different sand contents or adapting to different production needs, adjusting the inclined plate angle can optimize sedimentation and sand removal efficiency, giving the equipment greater adaptability and a wider range of applications.

[0038] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows: Example 1

[0039] A type of inclined plate sedimentation enhanced sand remover includes a body 3. A feeding hopper 1 is connected to the bottom of the body 3 via a collecting hopper 2. The bottom of the body 3 is supported by a second bracket 8. A first bracket 6 is installed inside the body 3. An inclined plate 9 is installed inside the body 3 via the first bracket 6. The bottom end of the inclined plate 9 is rotatably mounted on the first bracket 6. The rotatable mounting method of the bottom end of the inclined plate 9 provides a basis for the deflection of the inclined plate 9 within the body 3, allowing it to flexibly change its angle under the drive of the transmission mechanism 7. This not only facilitates the control of the sliding direction and speed of sand and gravel on the inclined plate 9, achieving automatic sand removal, but also allows for the adjustment of the angle of the inclined plate 9 at any time according to different working conditions and the sand content of the liquid, optimizing sedimentation efficiency and enhancing the adaptability of the equipment. The inclined plate 9 is equipped with a deflection mechanism 901, which deflects the inclined plate 9 within the machine body 3 via the deflection mechanism 901 and the transmission mechanism 7. The transmission mechanism 7 includes a lead screw 701 and a guide rod 702. A drive wheel 703 is installed at one end of the lead screw 701 located on the outside of the machine body 3. The lead screw 701 is connected to the external power equipment via the drive wheel 703. The combination of the lead screw 701, guide rod 702, and drive wheel 703 forms a stable and reliable transmission system. The lead screw 701 converts the rotational motion of the external power equipment into linear motion, precisely controlling the deflection angle of the inclined plate 9; the guide rod 702 acts as a guide, ensuring that the lead screw 701 does not deviate during transmission, making the angle adjustment of the inclined plate 9 more precise and stable. The connection between the drive wheel 703 and the external power equipment facilitates power transmission and control. Operators can flexibly turn the power equipment on or off as needed, enabling remote or automated adjustment of the angle of the inclined plate 9. A filter box 5 is mounted above the inclined plate 9, and a support beam 601 is provided on the first bracket 6. The filter box 5 is supported on the first bracket 6 by the support beam 601, which provides a stable support structure for the filter box 5, ensuring its stability during equipment operation and preventing displacement or shaking due to liquid flow impact, thus affecting the filtration effect. This installation method also makes the disassembly and installation of the filter box 5 more convenient, facilitating regular filter element replacement and maintenance of the equipment's filtration performance, reducing maintenance difficulty and time costs. The filter box 5 contains a filter element, and a through hole 501 is provided on its top. The filter element allows for secondary fine filtration of the liquid after initial sedimentation by the inclined plate 9, effectively trapping fine sand particles and impurities, significantly improving the liquid's cleanliness. The through holes 501 on the filter box 5 provide a channel for liquid to enter the filter element. The reasonable layout of the through holes 501 can ensure that the liquid flows into the filter element evenly, give full play to the filtration function of the filter element, and improve filtration efficiency and quality. One end of the filter box 5 is connected to the liquid outlet pipe 4, and the end of the liquid outlet pipe 4 away from the filter box 5 passes through the body 3. The body 3 is provided with a liquid inlet pipe 301 at the inclined plate 9. Example 2

[0040] To achieve flexible and precise adjustment of the inclined plate angle to meet the high-efficiency sand removal requirements under different working conditions, for example, such as Figures 1 to 4 As shown, this utility model also includes: a connecting plate 903 rotatably mounted on the top of the inclined plate 9, and an upper connecting plate 902 mounted on the top of the connecting plate 903. The upper connecting plate 902 meshes with the lead screw 701 of the transmission mechanism 7 for transmission. The upper position of the inclined plate 9 is adjusted by the cooperation of the lead screw 701 and the upper connecting plate 902. The meshing transmission design of the connecting plate 903, the upper connecting plate 902, and the lead screw 701 constitutes the key transmission link for adjusting the angle of the inclined plate 9. Through the meshing of the lead screw 701 and the upper connecting plate 902, the linear motion of the lead screw 701 can be accurately transmitted to the inclined plate 9, realizing the fine adjustment of the angle of the inclined plate 9. This transmission method not only boasts high transmission efficiency but also a compact structure and small footprint. It can withstand various forces during the deflection of the inclined plate 9, ensuring stable operation of the inclined plate 9 at different angles and improving the overall reliability of the equipment. The connecting plate 903 has sliding grooves 904 on both sides, and the upper connecting plate 902 has sliders at both ends. The upper connecting plate 902 is movably connected to the sliding grooves 904 of the connecting plate 903 via the sliders. This movable connection structure between the sliding grooves 904 and the sliders provides smooth guidance and constraint for the relative movement between the upper connecting plate 902 and the connecting plate 903. During the angle adjustment of the inclined plate 9, the upper connecting plate 902 slides within the sliding grooves 904 of the connecting plate 903 via the sliders, effectively preventing jamming caused by poor movement and ensuring the flexibility and continuity of the inclined plate 9 angle adjustment. Simultaneously, this structural design also disperses the force between the upper connecting plate 902 and the connecting plate 903, reducing component wear, extending equipment lifespan, and improving equipment operational stability.

[0041] The working principle of the above technical solution:

[0042] Liquid containing impurities such as sand and gravel flows into the machine body 3 through the inlet pipe 301, first entering the area of ​​inclined plate 9. According to the "shallow pool theory," the presence of inclined plate 9 increases the sedimentation area and shortens the settling distance of sand and gravel particles. As the liquid flows slowly between the inclined plates 9, solid impurities such as sand and gravel settle to the surface of the inclined plate 9 under the action of gravity, completing the initial solid-liquid separation. In this process, inclined plate 9 provides more sedimentation space, accelerating the separation efficiency.

[0043] In the transmission mechanism 7, the lead screw 701 is connected to an external power device via a drive wheel 703. When the angle of the inclined plate 9 needs to be adjusted, the external power device drives the drive wheel 703 to rotate, which in turn drives the lead screw 701 to rotate. When the lead screw 701 rotates, the upper connecting plate 902, which meshes with the lead screw 701, moves axially along the lead screw 701 under the guidance of the guide rod 702. Since the upper connecting plate 902 is connected to the top of the inclined plate 9 via a connecting plate 903, the movement of the upper connecting plate 902 will cause the inclined plate 9 to deflect around its bottom end within the machine body 3. By adjusting the angle of the inclined plate 9, the sliding speed and direction of the sand and gravel on the inclined plate 9 can be controlled, causing the sand and gravel deposited on the inclined plate 9 to slide down the inclined plate 9 and fall into the collection hopper 2 below, and then be discharged from the machine body 3 through the discharge hopper 1, effectively preventing sand accumulation and blockage on the surface of the inclined plate 9, and realizing automatic sand cleaning.

[0044] After initial sedimentation by inclined plate 9, the liquid continues to flow upwards and enters filter box 5. The filter element placed inside filter box 5 performs secondary filtration, further trapping fine sand particles and impurities. The liquid enters the filter element through the through-hole 501 on filter box 5. After filtration by the filter element, the clean liquid is discharged from the machine body 3 through the outlet pipe 4 connected to filter box 5, completing the entire sand removal process. Filter box 5 is placed on the first support 6 via support beam 601, facilitating the disassembly and replacement of the filter element and ensuring continuous filtration efficiency.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
