Description

Technical Field

[0001] This utility model relates to the field of oil and gas field development equipment technology, specifically to a fracturing fluid preparation filling machine. Background Technology

[0002] In oil and gas field fracturing operations, the efficiency and quality of fracturing fluid filling directly affect the construction progress and fracturing effect. Existing fracturing fluid preparation and filling machines suffer from insufficient filling accuracy. The lifting devices mostly use single-rail guidance or rigid transmission, and the injection port is prone to misalignment with the container due to vibration or transmission deviation, resulting in fracturing fluid leakage. This not only wastes raw materials but may also affect the performance of the fracturing fluid due to impurities.

[0003] According to the published information on the filling machine (Announcement No.: CN219635529U), it includes: a machine body and a slider slidably mounted on the machine body, as well as a filling mechanism and a cap removal and tightening mechanism mounted on the machine body. The slider carries the packaging material and drives the packaging material to reciprocate between the filling mechanism and the cap removal and tightening mechanism. When the slider moves the packaging material to the working area of ​​the filling mechanism, the filling mechanism fills the packaging material. When the slider moves the packaging material to the working area of ​​the cap removal and tightening mechanism, the cap removal and tightening mechanism removes or tightens the cap of the packaging material. The filling machine designed by this utility model can automatically tighten and loosen the cap of the packaging material before and after filling, shortening the filling and cap tightening time and path, and reducing the risk of contamination of the medicine liquid in the packaging material during filling.

[0004] In the above application, the automatic screwing of the packaging cap is achieved through the filling mechanism and the cap screwing mechanism. However, the injection port is prone to misalignment with the container due to vibration or transmission deviation, resulting in fracturing fluid leakage. Therefore, we propose a filling machine for fracturing fluid preparation. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a fracturing fluid preparation filling machine, which solves the technical problems of low filling accuracy, poor equipment stability and cumbersome cleaning and maintenance in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a fracturing fluid preparation filling machine, comprising: a machine base, a vertical plate fixedly connected to the top of the machine base, a movable plate slidably connected to the side of the vertical plate, an injection port fixedly connected to one end of the movable plate, a turntable rotatably connected to the top of the machine base, a retention tank fixedly connected to the top of the machine base, a connecting pipe fixedly connected to the top of the retention tank, one end of the connecting pipe fixedly connected to the top of the injection port, and a lifting device provided on the side of the machine base;

[0007] The lifting device includes a base, the side of which is fixedly connected to the side of the machine base. A motor is mounted on the top of the base. A support plate is rotatably connected to the circumferential surface of the motor's output shaft. An eccentric wheel inner ring is fixedly connected to the output end of the motor. An eccentric wheel outer ring is fixedly connected to the side of the inner ring. A roller is rotatably connected to the circumferential surface of the inner ring. A transmission plate is fixedly connected to one end of the roller. A positioning plate is rotatably connected to the side of the transmission plate. The bottom of the positioning plate is fixedly connected to the top of the base. A transmission rod is slidably connected to the side of the transmission plate. A slide rail is fixedly connected to the top of the machine base. The side of the slide rail passes through and is slidably connected to the top of the moving plate. One end of the transmission rod passes through and is fixedly connected to the side of the moving plate.

[0008] For example, in at least one embodiment of the present invention, a fracturing fluid preparation filling machine further includes: a motor base fixedly connected to the circumferential surface of the motor, and the bottom of the motor base fixedly connected to the top of the device base. The motor base can enhance the stability of the motor installation, reduce the transmission of vibration from the motor during operation to the device base, avoid vibration affecting transmission accuracy, and extend the service life of the motor.

[0009] Three connecting plates are fixedly connected to the side of the inner ring of the eccentric wheel, and all three are arranged in a circumferential array on the side of the inner ring of the eccentric wheel. The three circumferentially arrayed connecting plates can enhance the connection rigidity between the inner and outer rings of the eccentric wheel, avoid deformation of the eccentric wheel caused by long-term high-frequency transmission, ensure synchronous movement of the inner and outer rings of the eccentric wheel, and improve the transmission stability of the lifting device.

[0010] The transmission plate has a groove on its side, and the end of the transmission rod closest to the transmission plate is slidably connected inside the groove. The groove design allows the transmission rod to slide adaptively along the groove when the transmission plate swings, reducing rigid friction and stress concentration during transmission, avoiding component jamming or wear, and improving the smoothness of lifting and lowering actions and the service life of components.

[0011] The slide rails are arranged in four symmetrical configurations along the vertical central axis of the slide rails. The inner wall of the movable plate is slidably connected to the slide rails. The four symmetrical slide rails provide all-around guidance for the movable plate, ensuring the verticality of the movable plate and injection port during lifting and lowering. This avoids misalignment between the filling port and the container due to tilting, thereby improving the accuracy and stability of fracturing fluid filling.

[0012] According to another aspect, at least one embodiment of the present invention also provides a fracturing fluid preparation filling machine, comprising: a cleaning device, the cleaning device including a water tank, the bottom of the water tank being fixedly connected to the top of the machine base, a sliding rod being slidably connected to the top of the water tank, a pressure plate being fixedly connected to one end of the sliding rod, a spring being provided on the circumferential surface of the sliding rod, one end of the spring being fixedly connected to the top of the water tank, the other end of the spring being fixedly connected to the bottom of the pressure plate, a water spray pipe being fixedly connected to the side of the water tank, a water collection shell being provided on the circumferential surface of the turntable, the bottom of the water collection shell being fixedly connected to the top of the machine base, and a drain pipe being fixedly connected to the circumferential surface of the water collection shell.

[0013] For example, in at least one embodiment of the present invention, a fracturing fluid preparation and filling machine further includes: a water level groove provided on the side of the water tank, and a filling port fixedly connected to the side of the water tank. The water level groove allows for real-time observation of the water level in the tank, facilitating timely detection of water shortage, while the filling port simplifies the water replenishment operation, allowing for quick water replenishment without disassembling parts, thus improving the convenience of equipment maintenance.

[0014] The top of the pressure plate is located on the displacement trajectory of the transmission rod, and an extended pressing plate is fixedly connected to one end of the transmission rod near the pressure plate. The extended pressing plate ensures stable contact between the transmission rod and the pressure plate during lifting and lowering, avoiding trigger failure due to displacement deviation, thereby reliably driving the cleaning device.

[0015] The bottom of the extended extrusion plate is located on the displacement trajectory of the pressure plate, and the bottom of the extended extrusion plate does not contact the top of the water tank. Contact between the extended extrusion plate and the pressure plate ensures uniform force distribution on the pressure plate and avoids localized deformation.

[0016] The slide bar and spring are provided in pairs, and are symmetrical to each other along the vertical central axis of the pressure plate. The symmetrically distributed slide bar can provide precise guidance for the pressure plate, preventing it from tilting or jamming during lifting and lowering, while the symmetrical spring provides balanced rebound force, ensuring smooth reset of the pressure plate.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] 1. In this utility model, the lifting device reduces vibration through the motor base, enhances rigidity through the eccentric wheel connecting plate, reduces transmission friction through the slide groove, and is guided by four sets of symmetrical slide rails to ensure that the moving plate and injection port are lifted smoothly and vertically accurately, avoid filling alignment deviation, improve the stability and accuracy of fracturing fluid filling, reduce leakage risk, and extend the service life of components.

[0019] 2. In this utility model, the cleaning device facilitates water replenishment through the water level tank and the filling port, achieves automatic cleaning by extending the linkage transmission rod of the extrusion plate, ensures the stable reset of the pressure plate by the symmetrical slide rod and spring, and recovers wastewater by the water collection shell and the drain pipe, thereby improving the degree of automation of cleaning, avoiding cumbersome manual operation, protecting the components from damage, and reducing maintenance costs.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-4This invention illustrates a fracturing fluid preparation filling machine according to one embodiment of the present invention, comprising: a machine base 1, a vertical plate 2 fixedly connected to the top of the machine base 1, a movable plate 3 slidably connected to the side of the vertical plate 2, an injection port 4 fixedly connected to one end of the movable plate 3, a turntable 5 rotatably connected to the top of the machine base 1, a retention tank 6 fixedly connected to the top of the machine base 1, a connecting pipe 7 fixedly connected to the top of the retention tank 6, one end of the connecting pipe 7 fixedly connected to the top of the injection port 4, and a lifting device 8 provided on the side of the machine base 1;

[0033] The lifting device 8 includes a device base 801, the side of which is fixedly connected to the side of the machine body base 1. A motor 802 is installed on the top of the device base 801. A support plate 803 is rotatably connected to the circumferential surface of the output shaft of the motor 802. An eccentric wheel inner ring 804 is fixedly connected to the output end of the motor 802. An eccentric wheel outer ring 805 is fixedly connected to the side of the eccentric wheel inner ring 804. A roller 806 is rotatably connected to the circumferential surface of the eccentric wheel inner ring 804. A transmission plate 807 is fixedly connected to one end of the roller 806. A positioning plate 808 is rotatably connected to the side of the transmission plate 807. The bottom of the positioning plate 808 is fixedly connected to the top of the device base 801. A transmission rod 809 is slidably connected to the side of the transmission plate 807. A slide rail plate 810 is fixedly connected to the top of the machine body base 1. The side of the slide rail plate 810 passes through and is slidably connected to the top of the moving plate 3. One end of the transmission rod 809 passes through and is fixedly connected to the side of the moving plate 3.

[0034] In some examples, a motor base 811 is fixedly connected to the circumferential surface of the motor 802, and the bottom of the motor base 811 is fixedly connected to the top of the device base 801. The motor base 811 can enhance the stability of the motor 802 installation, reduce the transmission of vibration from the motor 802 during operation to the device base 801, avoid vibration affecting transmission accuracy, and extend the service life of the motor 802.

[0035] Three connecting plates are fixedly connected to the side of the inner ring 804 of the eccentric wheel, and they are arranged in a circumferential array on the side of the inner ring 804 of the eccentric wheel. The three circumferentially arrayed connecting plates can enhance the connection rigidity between the inner ring 804 and the outer ring of the eccentric wheel, avoid deformation of the eccentric wheel caused by long-term high-frequency transmission, ensure that the inner ring 804 and the outer ring of the eccentric wheel move synchronously, and improve the transmission stability of the lifting device 8.

[0036] A groove is provided on the side of the transmission plate 807, and the end of the transmission rod 809 near the transmission plate 807 is slidably connected inside the groove. The groove design allows the transmission rod 809 to slide adaptively along the groove when the transmission plate 807 swings, reducing rigid friction and stress concentration during transmission, avoiding component jamming or wear, and improving the smoothness of lifting and lowering actions and the service life of components.

[0037] The slide rail plate 810 has four slide rails, all symmetrically arranged along its vertical central axis. The inner wall of the movable plate 3 is slidably connected to the slide rails. The four symmetrical slide rails provide all-around guidance for the movable plate 3, ensuring the verticality of the movable plate 3 and the injection port 4 during lifting and lowering. This avoids misalignment between the filling port and the container due to tilting, thus improving the accuracy and stability of fracturing fluid filling.

[0038] For example, such as Figures 1-4 After the motor 802 starts, its output drives the inner ring 804 and outer ring 805 of the eccentric wheel to rotate synchronously. The inner ring 804 of the eccentric wheel pushes the transmission plate 807 to swing around the positioning plate 808 via the roller 806. When the transmission plate 807 swings, the transmission rod 809 slides along its side groove, driving the moving plate 3 to rise and fall along the four sets of symmetrical slide rails of the slide rail plate 810. The motor base 811 reduces vibration transmission, and the connecting plates of the three circumferential arrays enhance the rigidity of the eccentric wheel, ensuring that the moving plate 3 and the injection port 4 rise and fall smoothly, achieving precise alignment with the container on the turntable 5.

[0039] like Figures 1-4 This invention illustrates a fracturing fluid preparation and filling machine according to another embodiment of the present invention, comprising: a cleaning device 8, the cleaning device 8 including a water tank 901, the bottom of the water tank 901 being fixedly connected to the top of the machine base 1, a sliding rod 902 being slidably connected to the top of the water tank 901, a pressure plate 903 being fixedly connected to one end of the sliding rod 902, a spring 904 being provided on the circumferential surface of the sliding rod 902, one end of the spring 904 being fixedly connected to the top of the water tank 901, and the other end of the spring 904 being fixedly connected to the bottom of the pressure plate 903, a water spray pipe 905 being fixedly connected to the side of the water tank 901, a water collection shell 906 being provided on the circumferential surface of the turntable 5, the bottom of the water collection shell 906 being fixedly connected to the top of the machine base 1, and a drain pipe 907 being fixedly connected to the circumferential surface of the water collection shell 906.

[0040] In some examples, a water level groove 908 is provided on the side of the water tank 901, and a filling port 909 is fixedly connected to the side of the water tank 901. The water level groove 908 allows for real-time observation of the water level in the water tank 901, making it easy to detect water shortages in a timely manner. The filling port 909 simplifies the water replenishment operation, allowing for quick water replenishment without disassembling parts, thus improving the convenience of equipment maintenance.

[0041] The top of the pressure plate 903 is located on the displacement trajectory of the transmission rod 809, and an extension pressing plate 910 is fixedly connected to one end of the transmission rod 809 near the pressure plate 903. The extension pressing plate 910 ensures that the transmission rod 809 stably contacts the pressure plate 903 when it rises and falls, avoiding trigger failure due to displacement deviation, thereby reliably driving the cleaning device 9 to operate.

[0042] The bottom of the extended extrusion plate 910 is located on the displacement trajectory of the pressure plate 903, and the bottom of the extended extrusion plate 910 does not contact the top of the water tank 901. The contact between the extended extrusion plate 910 and the pressure plate 903 can make the pressure plate 903 evenly stressed and avoid local deformation.

[0043] There are two slide rods 902 and two springs 904, both of which are symmetrical about each other along the vertical central axis of the pressure plate 903. The symmetrically distributed slide rods 902 can provide precise guidance for the pressure plate 903, preventing it from tilting or jamming during lifting and lowering, while the symmetrical springs 904 provide balanced rebound force to ensure that the pressure plate 903 returns to its original position smoothly.

[0044] For example, such as Figures 1-4 When the transmission rod 809 descends, its extended pressing plate 910 presses against the pressure plate 903, causing the slide rod 902 to slide down the top of the water tank 901 and compress the spring 904. Water in the water tank 901 is sprayed out through the sprinkler pipe 905 to clean the turntable 5 and its surrounding area. After the transmission rod 809 rises, the spring 904 returns to its original position, pushing the pressure plate 903 back up. The symmetrically distributed slide rods 902 ensure a smooth return. Cleaning wastewater flows into the water collection shell 906 and is discharged through the drain pipe 907. The water level tank 908 facilitates observation of the water level, and the filling port 909 allows for timely water replenishment.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
