Description

Technical Field

[0001] This invention relates to the field of foaming agent filling technology, and in particular to an automatic quantitative filling machine for foaming agent production applied to shale gas wells. Background Technology

[0002] Currently, foaming agents for shale gas wells are chemical agents used to improve the production efficiency of shale gas wells. They are mainly composed of surfactants, additives, and other components. The working principle of foaming agents is to reduce the surface tension of gas and liquid, causing the liquid at the bottom of the well to form stable foam, which then carries the liquid smoothly to the wellhead, greatly reducing the obstruction of gas production caused by the liquid at the bottom of the well. For example, some common surfactants, such as anionic surfactants and nonionic surfactants, can effectively enhance the stability of the foam and its liquid-carrying capacity. The addition of additives can improve the temperature resistance, salt resistance, and other properties of the foaming agent to better adapt to the complex downhole environment of shale gas wells. In practical applications, depending on the different conditions of shale gas wells, it is necessary to carefully select the appropriate foaming agent formula and concentration to obtain the most ideal liquid drainage effect and effectively improve shale gas production. It can be seen that foaming agents are indeed necessary additives for improving the production efficiency of shale gas wells. Currently, shale gas well filling and processing is a crucial step in the shale gas extraction process. It encompasses the collection, processing, filling, and storage of shale gas extracted from wells. Chinese patent publication number "CN219730529U" discloses an adhesive quantitative filling machine, which includes a base with an mounting arm at one end. The mounting arm is equipped with a storage tank and a filling head. A turntable is rotatably mounted at the center of the top of the base, and multiple limiting plates are arranged on the sides of the turntable's upper surface. The positioning plates are on the same circular track, the limiting plate has a U-shaped structure and the opening of the limiting plate faces the outside of the turntable. The mounting arm is equipped with a sealing component that can seal the opening of the limiting plate. The top of the base is equipped with a conveyor rail at the end away from the mounting arm, and the end of the conveyor rail away from the turntable is equipped with a downwardly inclined sliding plate. The structure of this utility model is reasonable, which can achieve continuous filling operation of adhesives. It has a positioning function for adhesive filling barrels, has high applicability, and is convenient for loading and unloading, with low labor intensity, making it more practical. However, while the aforementioned device can assist in some automatic filling functions during practical application, it still has certain defects and shortcomings. It uses an electric push rod to assist in clamping and positioning the sealing component for the foaming agent packaging can. However, it is difficult to adapt to different sizes of foaming agent packaging cans during use. In actual packaging, different sizes of foaming agent packaging cans are often used to package products, and different sizes can meet different sales needs. These cans obviously have different diameters. The existing technical solution uses an arc-shaped groove and an arc-shaped limiting plate for clamping, but the inner slope of these grooves and the limiting plate can only clamp a single specific diameter can. Once the size of the can changes, it is obviously difficult to ensure that the inlet of the can is accurately aligned with the discharge pipe at the bottom of the tubular machine. Therefore, the existing technology has certain defects and shortcomings, and urgently needs improvement. Summary of the Invention

An actuating rod is fixedly installed through the concave frame at the output end of the third motor.

[0005] Furthermore, the positioning mechanism includes a first motor, which is fixedly installed at the bottom center of the top seat. The output end of the first motor passes through the top seat and is fixedly installed with a turntable. The turntable is rotatably connected to the top center of the top seat. Drive components are fixedly installed at equal intervals on the bottom outer side of the turntable. Clamping components are fixedly installed at both ends of the top of the drive components.

[0006] Furthermore, a foaming agent feeding pipe is fixedly installed on the middle of one side of the upper end of the foaming agent filling machine body, and a flange is fixedly installed at the input end of the foaming agent feeding pipe.

[0007] Furthermore, the drive assembly includes a bottom rail, which is fixedly installed on the bottom of the turntable in a ring arrangement with equal spacing. A second motor is fixedly installed on one side of the bottom rail, and a lead screw is fixedly installed through the bottom rail at the output end of the second motor. The two ends of the lead screw have opposite thread directions, and both ends of the lead screw are threadedly connected to sliders. The top of the sliders is fixedly connected to the bottom of the clamping assembly.

[0008] Furthermore, the side shape of the slider and the overall cross-sectional shape of the internal cavity of the bottom rail are both set to a convex shape, and wear-resistant pads are fixedly connected to the inner wall of the bottom rail and the outer surface of the slider.

[0009] Furthermore, the clamping assembly includes a support rod, which is fixedly installed on the top of the slider. A clamping plate is fixedly installed on the top of the support rod, and a clamping groove is formed on the inner side of the clamping plate.

[0010] Furthermore, the overall cross-sectional shape of the clamping groove is V-shaped, a bonding plate is fixedly connected to one side of the clamping groove, and a power unit is fixedly connected to the other side of the clamping groove.

[0011] Furthermore, the power unit includes a concave seat, which is fixedly installed in the clamping groove on the side away from the bonding plate. The interior of the concave seat is rotatably connected to a second conveyor belt for the foaming agent tank, and the outer surface of the second conveyor belt for the foaming agent tank is provided with anti-slip stripe grooves at equal intervals.

[0012] Furthermore, the inner side of the bonding plate is rotatably connected with ball bearings at equal intervals, the outer side of the clamping plate is fixedly connected with a guide frame, and both ends of the guide frame are rotatably connected with guide rollers.

[0013] Compared with the prior art, the beneficial effects of the present invention are: Firstly, in this invention, the device is equipped with a positioning mechanism. In use, the foaming agent packaging can is placed on the upper foaming agent can first conveyor belt, and then conveyed to the top of the turntable, located inside the two clamping plates. The second motor is started to drive the lead screw to rotate. Because the threads at both ends of the lead screw rotate in opposite directions, the slider is driven to slide so that the clamping plates hold and fix the foaming agent packaging can. The clamping groove is V-shaped, which can center and position foaming agent packaging cans of different sizes by contacting them with the internal inclined surface. When feeding, the guide roller shaft rotates so that the foaming agent packaging can stably enter the top of the turntable, realizing flexible clamping and positioning and automated feeding, thereby improving processing efficiency.

[0014] Secondly, in this invention, the device uses a positioning mechanism in conjunction with a toggle mechanism. When in use, the first motor is started to drive the turntable to rotate, thereby flexibly adjusting the positioning position on the turntable to face the first conveyor belt of the foaming agent tank. After the foaming agent is filled, the foaming agent packaging tank is moved to the first conveyor belt of another foaming agent tank. The third motor is started to make the toggle plate push the foaming agent packaging tank. At the same time, the second motor drives the lead screw to separate the slider and the clamping plate. The first conveyor belts of the two foaming agent tanks and the positioning mechanism work together to realize automated quantitative packaging processing and improve production efficiency.

[0015] Thirdly, in this invention, the device is equipped with a power unit inside the clamping assembly. During filling, if the volume of the foaming agent packaging can is small, the second conveyor belt of the foaming agent can is started. Its inner side is attached to the inner side of the foaming agent packaging can, causing the foaming agent packaging can to slide upward. During this period, the foaming agent packaging can is attached to the ball bearings. The ball bearings roll to help the foaming agent packaging can approach the bottom discharge pipe of the foaming agent filling machine body, avoiding foaming agent splashing and improving the adaptability and filling efficiency of the device during foaming agent filling.

Detailed Implementation

[0018] Example Please see Figures 1-7 In this embodiment of the invention, an automatic quantitative filling machine for producing foaming agent for shale gas wells includes a base 1. Support legs 2 are fixedly installed at the four corners of the top of the base 1. A top seat 3 is fixedly installed on the top of the support legs 2. A support frame 4 is fixedly installed on the rear side of the top of the top seat 3. A foaming agent filling machine body 5 is fixedly installed on the top of the support frame 4. The bottom filling and discharging pipe of the foaming agent filling machine body 5 passes through the support frame 4. A toggle mechanism 6 is fixedly installed at the middle of the front end of the support frame 4. A top center of the top of the top seat 3 is fixedly installed... There is a positioning mechanism 7. A first motor 71 is fixedly installed in the middle of the bottom of the top seat 3. The output end of the first motor 71 passes through the bottom of the top seat 3 and is fixedly connected to the bottom of the positioning mechanism 7. A mounting bracket 9 is fixedly installed on one side of the top and one side of the bottom of the top seat 3. The two mounting brackets 9 are set vertically. The inner side of the mounting bracket 9 is rotatably connected to the first conveyor belt 10 of the foaming agent tank. One first conveyor belt 10 of the foaming agent tank is set on the upper side of the positioning mechanism 7, and the other first conveyor belt 10 of the foaming agent tank is set on the lower side of the positioning mechanism 7. The actuating mechanism 6 includes a telescopic cylinder 61, which is fixedly installed at the front center of the support frame 4. A concave frame 62 is fixedly installed at the bottom output end of the telescopic cylinder 61, and a third motor 63 is fixedly installed on the front of the concave frame 62. An actuating rod 64 is fixedly installed through the output end of the third motor 63 through the concave frame 62. By driving the concave frame 62 and the actuating rod 64 driven by the third motor 63 through the telescopic cylinder 61, precise actuation operation can be achieved. The positioning mechanism 7 at the top center of the top seat 3, together with the first motor 71 at the bottom, can ensure precise positioning. Two vertically arranged first conveyor belts 10 for foaming agent tanks are rotatably connected to the mounting brackets 9 on the top and bottom sides of the top seat 3. One is located at the upper end of the positioning mechanism 7 and the other at the lower end. This layout makes the entire filling process smoother and more efficient. The overall structure is reasonably designed, and the components work together to improve the accuracy and efficiency of foaming agent filling, reduce the complexity and error of manual operation, and help improve the production quality and output of foaming agent for shale gas wells.

[0019] Please see Figures 1-3 and Figures 5-7 The positioning mechanism 7 includes a first motor 71, which is fixedly installed in the middle of the bottom of the top seat 3. The output end of the first motor 71 passes through the top seat 3 and is fixedly installed on a turntable 72. The turntable 72 is rotatably connected to the middle of the top of the top seat 3. Drive components 73 are fixedly installed at equal intervals on the outer bottom of the turntable 72. Clamping components 74 are fixedly installed at both ends of the top of the drive components 73. The first motor 71 is fixedly installed in the middle of the bottom of the top seat 3, and its output end passes through the top seat 3 and is connected to the turntable 72, thereby driving the turntable 72 to rotate in the middle of the top of the top seat 3. The drive components 73 are fixedly installed at equal intervals on the outer bottom of the turntable 72, and clamping components 74 are fixedly installed at both ends of the top of the drive components 73. These components work together to achieve precise positioning and stable clamping of the filling object, providing an important guarantee for efficient and accurate filling operations.

[0020] Please see Figures 1-2 A foaming agent feeding pipe 11 is fixedly installed on the middle of one side of the upper end of the foaming agent filling machine body 5. A flange 8 is fixedly installed at the input end of the foaming agent feeding pipe 11. The flange 8 facilitates the connection with external feeding equipment and ensures that the foaming agent can be stably and smoothly fed into the foaming agent filling machine body 5 through the foaming agent feeding pipe 11, providing a sufficient supply of foaming agent for subsequent filling work.

[0021] Please see Figures 1-3 and Figures 5-7The drive assembly 73 includes a base rail 731, which is fixedly installed on the bottom of the turntable 72 in a ring-shaped arrangement at equal intervals. A second motor 732 is fixedly installed on one side of the base rail 731. A lead screw 733 is fixedly installed through the base rail 731 at the output end of the second motor 732. The two ends of the lead screw 733 have opposite threads, and both ends of the lead screw 733 are threadedly connected to sliders 734. The top of the sliders 734 is fixedly connected to the bottom of the clamping assembly 74. The side shape of the sliders 734 and the overall cross-sectional shape of the internal cavity of the base rail 731 are both set as convex. Wear-resistant pads are fixedly connected to the inner wall of the base rail 731 and the outer surface of the sliders 734. The base rails 731 are fixedly installed on the bottom of the top plate in a ring-shaped arrangement at equal intervals, providing a stable foundation support for the entire assembly. The second motor 732 on one side drives the drive through the base rail. The lead screw 733 of the 731 features a clever design with opposite thread directions at both ends, allowing the sliders 734 at both ends to move synchronously in opposite directions when the lead screw 733 rotates. This enables precise and efficient clamping or releasing of the clamping assembly 74. The top of the slider 734 is fixedly connected to the bottom of the clamping assembly 74, ensuring reliable motion transmission. The overall cross-sectional shape of the slider 734's side and the internal cavity of the bottom rail 731 is convex, enhancing the stability and guidance of the slider 734 as it slides within the bottom rail 731 and preventing it from deviating. The wear-resistant pads fixedly connected to the inner wall of the bottom rail 731 and the outer surface of the slider 734 effectively reduce friction and wear, extending the service life of the assembly, reducing maintenance costs, and ensuring the stable performance and reliable precision of the drive assembly 73 during long-term use.

[0022] Please see Figures 5-7 The clamping assembly 74 includes a support rod 741, which is fixedly installed on the top of the slider 734. A clamping plate 742 is fixedly installed on the top of the support rod 741. A clamping groove 743 is formed on the inner side of the clamping plate 742. The overall cross-sectional shape of the clamping groove 743 is V-shaped. A bonding plate 744 is fixedly connected to one side of the clamping groove 743, and a power unit 745 is fixedly connected to the other side of the clamping groove 743. The support rod 741 is fixedly installed on the top of the slider 734, and the clamping plate 742 on its top is used to directly perform the clamping operation. The overall cross-sectional shape of the clamping groove 743 formed by the clamping plate 742 is V-shaped. This design can better adapt to objects of different sizes and shapes. The bonding plate 744 fixedly connected to one side of the clamping groove 743 helps to enhance the tightness of contact with the clamped object and improve the stability of the clamping. The power unit 745 fixedly connected to the other side of the clamping groove 743 provides power for the clamping action, ensuring efficient and reliable clamping.

[0023] Please see Figure 7The power unit 745 includes a concave seat 7451, which is fixedly installed in the clamping groove 743 on the side away from the bonding plate 744. A second conveyor belt 7452 for the foaming agent tank is rotatably connected inside the concave seat 7451. Anti-slip grooves 7453 are evenly spaced on the outer surface of the second conveyor belt 7452. Ball bearings 746 are rotatably connected at equal intervals to the inner side of the bonding plate 744. A guide frame 747 is fixedly connected to the outer side of the clamping plate 742. Guide rollers 748 are rotatably connected to both ends of the guide frame 747. The concave seat 7451 is fixedly installed in the clamping groove 743 on the side away from the bonding plate 744, and the second conveyor belt 7452 rotatably connected inside provides power for the clamping action. The anti-slip grooves 7453 evenly spaced on the outer surface of the second conveyor belt 7452 of the foaming agent tank increase friction and prevent slippage. The ball bearings 746 rotatably connected at equal intervals on the inner side of the bonding plate 744 reduce friction and make clamping smoother. The guide rollers 748 rotatably connected at both ends of the guide frame 747 on the outer side of the clamping plate 742 play a guiding role, ensuring that the object moves in the correct direction during clamping. In summary, the guide frame 747 and the guide rollers can assist in guiding the foaming agent packaging tank to enter the inner side of the clamping plate 742. The operation of the second conveyor belt 7452 of the foaming agent tank, in conjunction with the guidance of the ball bearings 746, can lift the foaming agent packaging tank, which can improve the overall adaptability of the device and avoid the foaming agent from splashing.

[0024] The working principle of this invention is as follows: By setting the positioning mechanism 7, during use, the foaming agent packaging can is placed on the first conveyor belt 10 of the foaming agent packaging can located at the upper end. At this time, the operation of the first conveyor belt 10 of the foaming agent packaging can assist in conveying the foaming agent packaging can to the top of the turntable 72. When the foaming agent packaging can enters the top of the turntable 72, it is located between the inner sides of the two clamping plates 742. By starting the second motor 732, the second motor 732 drives the lead screw 733 to rotate. The two ends of the lead screw 733 have opposite threads, which in turn assists in driving the sliders 734 to slide against each other. The two sliders 734 slide synchronously, that is... The clamping plate 742 can clamp and fix the foaming agent packaging can. During the clamping of the foaming agent packaging can, the V-shaped clamping groove 743 can abut against the foaming agent packaging can through the internal inclined guide, which can adapt to foaming agent packaging cans of different sizes for centered clamping and positioning. This allows the device to flexibly adapt to different sizes of packaging cans for clamping and positioning during the overall application. At the same time, during the feeding process, the guide roller shaft 748 on the guide frame 747 can rotate to make the foaming agent packaging can enter the top of the turntable 72 relatively stably. This allows the equipment to have strong clamping and adaptation capabilities and can perform automated feeding, improving processing efficiency.

[0025] By setting up a positioning mechanism 7 in conjunction with a toggle mechanism 6, the device can be operated by starting the first motor 71, which drives the turntable 72 to rotate. The rotation of the turntable 72 can synchronously drive the foaming agent packaging cans clamped and positioned on the turntable 72 to rotate, thereby flexibly adjusting the orientation of each positioning station on the turntable 72 towards the first conveyor belt 10 of the foaming agent cans. This allows the device to move the foaming agent packaging cans to another first conveyor belt 10 of the foaming agent cans after filling. At this time, starting the third motor 63 drives the toggle plate to push the foaming agent packaging cans inside the clamping plate 742. At this time, starting the second motor 732 drives the lead screw 733 to drive the slider 734 to separate in the opposite direction, thereby causing the clamping plates 742 to separate from each other. This facilitates the automatic transfer of the foaming agent packaging cans to the top of the first conveyor belt 10 of the other foaming agent cans. The two sets of first conveyor belts 10 of the foaming agent cans, together with the positioning mechanism 7, can perform automated quantitative packaging processing, which can improve the overall production efficiency of the equipment.

[0026] By incorporating a power unit 745 within the clamping assembly 74, during the filling process, if the foaming agent packaging can is small, the second conveyor belt 7452 can be activated when the can is moved to the bottom of the foaming agent filling machine body 5. Since the inner side of the second conveyor belt 7452 is in close contact with the inner side of the foaming agent packaging can, the second conveyor belt 7452 can drive the foaming agent packaging can to slide upwards. During this process, the can is in close contact with the ball bearings 746, which help to move the can upwards towards the bottom discharge pipe of the foaming agent filling machine body 5. By ensuring contact between the can and the bottom discharge pipe, splashing of the foaming agent is avoided, improving the overall adaptability of the device and preventing splashing, thus increasing the filling efficiency of the equipment.
