[0040] The present invention will be further described below with reference to the accompanying drawings.
[0041] Firstly, see Figures 1-5 An embodiment of this application provides a chemical dosing device for a gas production well, comprising a chemical tank 1, a stirring mechanism 2, and a buffer mechanism 3. The stirring mechanism 2 is disposed inside the chemical tank 1 and is used to stir the chemical in the chemical tank 1. The chemical tank 1 is disposed inside the buffer mechanism 3, which includes a housing 31, a first buffer assembly 32, and a second buffer assembly 33. The first buffer assembly 32 is disposed inside the housing 31 and located at the bottom of the housing 31, with the bottom of the chemical tank 1 abutting against the first buffer assembly 32. The second buffer assembly 33 is disposed on the inner side wall of the housing 31 and can abut against the outer side wall of the chemical tank 1.
[0042] The gas well dosing device provided in this embodiment of the application sets the dosing tank 1 inside the buffer mechanism 3, with the bottom of the tank abutting against the first buffer component 32 and the outer wall of the tank abutting against the second buffer component 33. This causes the tank 1 to vibrate under the action of the stirring mechanism 2 when the stirring mechanism 2 inside the tank 1 stirs the chemicals. The first buffer component 32 and the second buffer component 33, which are abutting against the tank 1, resonate with the tank 1 when the tank 1 vibrates, thereby buffering the tank and making the stirring process more stable. The chemicals can be better and more fully stirred, which greatly improves the dosing efficiency of the gas well dosing device. In addition, it can reduce the noise generated by resonance and greatly improve the comfort of the user.
[0043] In this embodiment, the chemicals in the medicine tank 1 are flocculants, scale inhibitors, corrosion inhibitors, and demulsifiers. Of course, in other embodiments, operators may add different chemicals according to specific needs, which will not be elaborated here.
[0044] like Figure 2 As shown, in some embodiments, the first buffer assembly 32 includes a buffer frame 321 and a damping spring 322. The buffer frame 321 is disposed inside the housing 31 and located at the bottom of the housing 31. The buffer frame 321 abuts against the bottom of the medicine barrel 1. The damping spring 322 is disposed on the buffer frame 321.
[0045] By placing the medicine tank 1 into the buffer mechanism 3 and making the buffer frame 321 equipped with the damping spring 322 abut against the bottom of the medicine tank 1, the medicine tank 1 can resonate with the buffer frame 321 equipped with the damping spring 322 when the medicine tank 1 shakes, thereby buffering the medicine tank, making the stirring process more stable, the medicine can be better and more fully stirred, greatly improving the dosing efficiency, and reducing the noise generated by resonance, thus improving the comfort of the user.
[0046] In this embodiment, the damping spring 322 is arranged axially along a first direction X, which is the axial direction of the medicine barrel 1.
[0047] like Figure 3 As shown, specifically, the buffer frame 321 includes a buffer support column, which includes a top plate, a bottom plate, and a sliding rod. One end of the sliding rod is fixedly connected to the top plate, and the other end is fixedly connected to the bottom plate. The bottom plate is fixed inside the housing 31 and located at the bottom of the housing 31. The damping spring 322 is sleeved on the sliding rod, and its two ends abut against the top plate and the bottom plate respectively.
[0048] In addition, at least one buffer support is provided. When two or more buffer supports are provided, the buffer frame 321 also includes a connecting rod 511. The two ends of the connecting rod 511 are connected to different buffer supports respectively. By connecting different buffer supports through the connecting rod 511, the buffering effect between different buffer supports can be balanced, thereby further improving the buffering effect on the medicine tank, making the stirring process more stable, and the medicine can be better and more fully stirred.
[0049] like Figure 2 As shown, in some embodiments, the second buffer assembly 33 includes a damping rod 332, a buffer seat 331, and a buffer rod 333. The buffer seat 331 is fixed to the inner side wall of the housing 31. One end of the damping rod 332 is disposed inside the buffer seat 331, and the other end is fixedly connected to the buffer rod 333. The buffer rod 333 abuts against the outer side wall of the medicine barrel 1.
[0050] Specifically, in this embodiment, the damping rod 332 is arranged along the second direction Y, which is the radial direction of the medicine barrel 1, and the first direction X is perpendicular to the second direction Y.
[0051] In this embodiment, the damping rod 332 is a hydraulic damping rod, which consists of an outer cylinder, a piston, a piston rod, hydraulic oil, and a valve. The piston divides the outer cylinder into upper and lower chambers, and the valve controls the flow of hydraulic oil to generate damping force, thereby achieving buffering.
[0052] In other embodiments, the damping rod 332 may also be a pneumatic damping rod, a mechanical damping rod, an electromagnetic damping rod, or a composite damping rod, depending on the actual application. The specific structure of the damping rod will not be described in detail here.
[0053] By placing the medicine tank 1 into the buffer mechanism 3 and making the buffer rod 333 abut against the outer wall of the medicine tank 1, the medicine tank 1 can resonate with the damping rod 332, the buffer rod 333 and the buffer seat 331 when the medicine tank 1 shakes, thereby buffering the medicine tank, making the stirring process more stable, the medicine can be better and more fully stirred, greatly improving the dosing efficiency, and reducing the noise generated by resonance, thus improving the comfort of the user.
[0054] like Figure 2 As shown, in some embodiments, the second buffer assembly 33 includes at least two, and the two second buffer assemblies 33 are respectively disposed opposite to each other on the inner sidewall of the housing 31.
[0055] By providing at least two second buffer components 33 on the inner wall of the shell 31, the buffering effect on the medicine tank is better when the medicine tank 1 shakes, making the stirring process more stable, the medicine can be better and more fully stirred, and the dosing efficiency is greatly improved.
[0056] like Figure 4 As shown, in some embodiments, the stirring mechanism 2 includes a drive motor 21, a rotating shaft 22, and a stirring rod 23. The drive motor 21 is fixed to the medicine barrel 1, the rotating shaft 22 is fixed to the output end of the drive motor 21 and located inside the medicine barrel 1, and the stirring rod 23 is fixed on the rotating shaft 22. The drive motor 21 can drive the rotating shaft 22 to rotate the stirring rod 23.
[0057] By setting a rotating shaft 22 and a stirring rod 23 inside the medicine tank 1, and driving the rotating shaft 22 to rotate the stirring rod 23 by the drive motor 21, the medicine in the medicine tank 1 can be stirred, thereby making the medicine in the medicine tank 1 more uniform and thus greatly improving the dosing efficiency.
[0058] In some embodiments, the stirring mechanism 2 further includes a stirring frame 24 and a scraper 25. The stirring frame 24 is fixed on the rotating shaft 22, and the scraper 25 is fixed on the stirring frame 24. The drive motor 21 can drive the rotating shaft 22 to rotate the stirring frame 24 so that the scraper 25 can rotate along the inner wall of the medicine barrel 1.
[0059] By fixing a stirring frame 24 to the rotating shaft 22 and fixing a scraper rod 25 on the stirring frame 24, the medicine that is squeezed and stuck to the outer wall can be scraped off by the scraper rod 25 when the stirring mechanism 2 stirs the medicine in the medicine tank 1, thus preventing the medicine from not flowing out of the medicine tank 1.
[0060] like Figure 5 As shown, in some embodiments, the gas well dosing device further includes a feeding mechanism 4, which includes a storage bladder 41 and a control valve 42. The storage bladder 41 is connected to the medicine tank 1, and a control valve 42 is provided between the storage bladder 41 and the medicine tank 1. The control valve 42 is used to control the connection and disconnection between the medicine tank 1 and the storage bladder 41.
[0061] By setting a control valve 42 between the storage sac 41 and the medicine barrel 1, the medicine flowing from the medicine barrel 1 into the storage sac 41 can be controlled, thereby controlling the amount of medicine dispensed. In addition, by setting the storage sac 41, the amount of medicine dispensed can be made more stable.
[0062] Specifically, the feeding mechanism 4 also includes an inlet pipe 43, a outlet pipe 44, and a chamber 45. The inlet pipe is used to connect the outlet of the control valve 42 and the inlet of the storage bladder 41. The outlet pipe 44 is located at the outlet of the storage bladder 41. In addition, the storage bladder 41, the inlet pipe 43, and the outlet pipe 44 are all located in the chamber 45, which can better protect the storage bladder 41, the inlet pipe 43, and the outlet pipe 44 from damage, thereby greatly extending their service life.
[0063] like Figure 6As shown, in some embodiments, the gas well dosing device further includes a support mechanism 5, which includes a telescopic component 51 and a support plate 52. One end of the telescopic component 51 is fixedly connected to the buffer mechanism 3, and the other end is fixedly connected to the support plate 52. The telescopic component 51 can adjust the relative position between the support plate 52 and the buffer mechanism 3.
[0064] By setting up the support plate 52 and the telescopic component 51, support can be provided for the buffer mechanism 3 and the chemical tank 1, thereby making the stirring process more stable and the chemical agent can be better and more fully stirred, greatly improving the dosing efficiency. In addition, by adjusting the height of the buffer mechanism 3 and the chemical tank 1 through the telescopic component 51, the chemical dosing device for gas production wells can be applied to more different gas production wells, greatly expanding its applicability.
[0065] Specifically, the telescopic assembly 51 includes a connecting rod 511, a telescopic rod 512, and a fixing member 513. One end of the telescopic rod 512 is fixedly connected to the buffer mechanism 3, and the other end is slidably connected to the connecting rod 511. The support plate 52 is fixed to the end of the connecting rod 511 away from the telescopic rod 512. The fixing member 513 is used to fix the relative position between the telescopic rod 512 and the connecting rod 511.
[0066] like Figure 1 and Figure 4 As shown, in some embodiments, the medicine barrel 1 is also provided with a medicine inlet, and a barrel cover 11 is provided on the medicine inlet.
[0067] Secondly, one embodiment of this application also provides a gas production well, including the above-mentioned gas production well dosing device, and also includes a storage tank, which is connected to the drug tank 1.
[0068] The agent is supplied to the drug tank 1 through the storage tank, and after being stirred by the stirring mechanism 2 inside the drug tank 1, the agent finally flows into the gas production well, thus solving the problems of preventing hydrate formation, corrosion and scale prevention, and cleaning pipelines during the gas production process.
[0069] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention.
