Description

Technical Field

[0001] The utility model relates to the technical field of unlocking fluid production, in particular to a production device for unlocking fluid for natural gas wells. Background Technique

[0002] A natural gas well is a wellhead facility for extracting underground natural gas resources. The main function of a natural gas well is to extract the underground natural gas to the ground, and then process and transport it. During the mining process, bonding occurs between the wellbore equipment and the well wall or other equipment. It is necessary to use unlocking fluid to remove the sediments, scale and other blockages in the wellbore, so as to restore the production capacity of the well.

[0003] The unlocking fluid can fully dissolve or loosen these sediments, thereby restoring the fluidity of the wellbore. The raw materials for the production and preparation of the unlocking fluid include solvents, acids, alkalis or surfactants. The selected solvent is mixed through a stirring device to ensure the uniformity of the solution mixture.

[0004] At present, most of the existing production devices for unlocking fluid for natural gas wells are equipped with a funnel above the production device. After weighing different preparation raw materials manually according to the ratio, the raw materials are poured into the funnel, and the raw materials are input into the production device through the funnel. Each batch requires manual proportioning, which has operational complexity and tediousness, and there are certain deviations in the ratio. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a production device for unlocking fluid for natural gas wells, which has the advantages of being able to maintain the unity of the raw materials for preparing each batch of unlocking fluid, effectively reducing the ratio deviation and the complexity and tediousness of manual operation, and solves the problems of deviation in the ratio of raw materials in each batch and complexity and tediousness in the current stage of using manual proportioning.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solution: A production device for unlocking fluid for natural gas wells, including a mixing component and a feeding component. The mixing component includes a mixing tank. A rotating rod is rotatably connected in the mixing tank. Stirring rods are fixed on the side of the rotating rod. And a connection interface is opened on the mixing tank. The connection interface communicates with the inside of the mixing tank. The inside of the mixing tank is in the shape of a horizontal cylindrical hollow groove. The stirring rods are attached to the inside of the groove to improve the stability of the rotation of the stirring rods. At the same time, a plurality of connection interfaces communicating with the inside are equidistantly opened on the mixing tank, so that each component raw material required for the production of the unlocking fluid can be transported into the mixing tank from the connection interfaces. And a one-way valve is installed at the connection interface, and the one-way valve is used to prevent liquid backflow.

[0009] The feeding component includes a feeding cylinder installed on the connection interface. A convex block is fixed on the side of the feeding cylinder. A lifting rod is movably sleeved in the convex block. One end of the lifting rod is fixed with a linkage plate. One end of the linkage plate is fixed with a linkage rod. One end of the linkage rod is fixed with a limiting cover plate. The limiting cover plate is movably sleeved in the feeding cylinder. Each raw material required for preparing the unlocking liquid is independently stored in different feeding cylinders. When the lifting rod moves up and down, it drives the linkage rod to move simultaneously through the linkage plate, so that the limiting cover plate moves up and down in the feeding cylinder, adjusting the capacity size in the feeding cylinder and achieving the effect of proportional feeding.

[0010] As a further improvement of the above solution, a driving motor is fixed on the side of the mixing box. The output end of the driving motor penetrates into the mixing box and is fixed at one end of a rotating rod.

[0011] Through the above technical solution, when the driving motor operates, its output end drives the rotating rod to rotate, so that the stirring rod on the side stirs the raw materials in the mixing box to make them fully mixed.

[0012] As a further improvement of the above solution, a feeding interface is provided on the side of the feeding cylinder.

[0013] Through the above technical solution, the feeding interface is located at the bottom end of the side of the feeding cylinder. After the limiting cover plate moves downward to adjust the space in the feeding cylinder, it can still convey the raw materials for preparation into the feeding cylinder.

[0014] As a further improvement of the above solution, a scale is provided on the side of the lifting rod.

[0015] Through the above technical solution, a scale is provided on the side of the lifting rod along its length direction. The scale values gradually decrease from the bottom end of the lifting rod upward. The maximum value at the bottom end of the lifting rod is the maximum capacity in the feeding cylinder, and the minimum value at the top end of the lifting rod is the minimum value of the space in the feeding cylinder. Therefore, when the lifting rod descends, the limiting cover plate also descends, and the remaining capacity space in the feeding cylinder can be understood by observing the scale.

[0016] As a further improvement of the above solution, a tooth profile groove is provided on the side of the lifting rod along its length direction. A control groove is provided on the side of the convex block. The control groove penetrates through the convex block. At the same time, a control gear is rotatably connected in the control groove, and the control gear meshes in the tooth profile groove.

[0017] Through the above technical solution, by moving the control gear up and down, under the acting force of meshing between the control gear and the tooth profile groove, the lifting rod moves up and down to adjust the height of the limiting cover plate in the feeding cylinder.

[0018] As a further improvement of the above solution, a threaded rod is movably sleeved inside the linkage rod. One end of the threaded rod penetrates through the limiting cover plate and is fixed with a feeding pressing plate. The limiting cover plate and the feeding pressing plate are attached to the inner wall of the feeding cylinder.

[0019] Through the above technical solution, when the threaded rod moves up and down, it drives the feeding pressing plate to press the raw materials in the cylinder downward, so that the raw materials are input into the mixing box from the connection interface.

[0020] As a further improvement of the above solution, a driving box is fixed on the top of the linkage plate. A driving gear and a rotating gear are rotatably connected inside the driving box, and a transmission toothed belt meshes with the sides of the two gears. At the same time, a threaded ring is fixed inside the rotating gear, and the threaded ring is threadedly connected to the side of the threaded rod.

[0021] Through the above technical solution, under the action of the meshing of the driving gear and the rotating gear with the transmission toothed belt, when the driving gear rotates, the transmission toothed belt is driven, so that the rotating gear rotates synchronously. When the rotating gear rotates, under the action of the threaded connection between the internal threaded ring and the side of the threaded rod, the threaded rod drives the feeding pressing plate to move up and down.

[0022] As a further improvement of the above solution, a micro motor is fixed on the top of the driving box. The output end of the micro motor penetrates into the driving box and is fixed on the driving gear.

[0023] Through the above technical solution, the output end of the micro motor has the function of bidirectional rotation. When the micro motor operates, its output end drives the driving gear to rotate. Under the action of the forward and reverse rotation of the output end, the threaded rod moves up and down.

[0024] As a further improvement of the above solution, a stable sliding groove is formed along the length direction on the side of the threaded rod. At the same time, a stable sliding block is fixed inside the linkage rod, and the stable sliding block is slidably connected in the stable sliding groove.

[0025] Through the above technical solution, when the threaded rod moves up and down, the stable sliding groove slides along the side of the stable sliding block, improving the stability of the lifting of the threaded rod. At the same time, it avoids the situation that the threaded rod rotates simultaneously when the threaded ring rotates.

[0026] Compared with the prior art, the present utility model provides a production device for unlocking liquid for natural gas wells, which has the following beneficial effects:

[0027] 1. The unlocking liquid production equipment for natural gas wells is equipped with multiple feeding cylinders on the mixing tank for storing different raw materials. By turning the regulating gear, the lifting rod moves up and down, driving the limiting cover plate to move up and down in the feeding cylinder, and adjusting and setting the capacity in the cylinder according to the proportion of each batch of unlocking liquid. When the raw materials are input into the cylinder body, as the threaded rod descends, the feeding pressing plate presses the raw materials in the cylinder body downward into the mixing tank. Thus, after each batch is completed, injecting the same volume of raw materials into the corresponding feeding cylinder can ensure the uniformity and consistency of the proportion of the unlocking liquid produced in each batch.

[0028] 2. On the side of the lifting rod of the unlocking liquid production equipment for natural gas wells, there are gradually decreasing capacity scales from bottom to top. When turning the regulating gear to move the lifting rod up and down, the limiting cover plate moves up and down in the feeding cylinder. By checking the scale value at the top position of the convex block, the remaining capacity space in the corresponding feeding cylinder can be understood, thereby improving the practicality and flexibility of the use of the feeding cylinder and enhancing the proportioning efficiency.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] Please refer to Figure 1-6 As shown, the unlocking liquid production equipment for natural gas wells proposed in this embodiment includes a mixing component 1 and a feeding component 2. The mixing component 1 includes a mixing tank 101. A rotating rod 103 is rotatably connected inside the mixing tank 101. A stirring rod 104 is fixed to the side of the rotating rod 103. And a connection interface 105 is opened on the mixing tank 101. The connection interface 105 communicates with the inside of the mixing tank 101. The inside of the mixing tank 101 is in a horizontal cylindrical hollow groove shape. The stirring rod 104 fits in the groove body to improve the stability of the rotation of the stirring rod 104. At the same time, a plurality of connection interfaces 105 communicating with the inside are equidistantly opened on the mixing tank 101. Thus, each component raw material required for the production of the unlocking liquid can be conveyed into the mixing tank 101 from the connection interface 105. And a one-way valve (not shown in the figure) is installed at the connection interface 105. The one-way valve is used to prevent liquid backflow.

[0041] The feeding assembly 2 includes a feeding barrel 201 installed on the connecting interface 105, a protrusion 203 is fixed on the side of the feeding barrel 201, a lifting rod 204 is movably sleeved in the protrusion 203, a linkage plate 206 is fixed at one end of the lifting rod 204, a linkage rod 207 is fixed at one end of the linkage plate 206, a limiting cover plate 208 is fixed at one end of the linkage rod 207, and the limiting cover plate 208 is movably sleeved in the feeding barrel 201. The raw materials required for preparing the unlocking liquid are independently stored in different feeding barrels 201. When the lifting rod 204 is lifted up and down, the linkage rod 207 is driven to move at the same time through the linkage plate 206, so that the limiting cover plate 208 moves up and down in the feeding barrel 201, and the capacity in the feeding barrel 201 is adjusted to achieve the effect of proportional feeding.

[0042] The working principle of the unlocking liquid production equipment for natural gas wells proposed in this embodiment is: when in use, one end of the external liquid supply pipeline is installed on the feed interface 202, and the tail end of the liquid supply pipeline is connected to the raw material supply devices required for preparation, and the regulating gear 2032 is turned so that the lifting rod 204 moves up and down under the force of the meshing between the side of the regulating gear 2032 and the tooth profile groove 2041, and the linkage plate 206 drives the linkage rod 207 to move up and down, so that the limiting cover plate 208 moves up and down in the feeding barrel 201, and the capacity in the barrel is adjusted, and the scale on the side of the lifting rod 204 is observed until the required height is reached (the scale on the scale 205 is designed to decrease from bottom to top). After there is a remaining capacity space in the feeding cylinder 201, stop turning the regulating gear 2032, and deliver the corresponding capacity of raw materials to the corresponding feeding cylinder 201 through the liquid supply pipeline, and then control the micro motor 216 to operate, and its output end drives the driving gear 210 to rotate, and transmits it through the transmission belt 212 to rotate the rotating gear 211. At this time, under the force of the threaded connection between the threaded ring 213 and the side of the threaded rod 214, the threaded rod 214 drives the feeding pressure plate 215 to move downward, and the raw materials in the cylinder are pressed and delivered into the mixing box 101 from the connecting interface 105, and when the driving motor 102 is in operation, its output end drives the stirring rod 104 to rotate, so that the raw materials are stirred and mixed.

[0043] Furthermore, a driving motor 102 is fixed to the side of the mixing box 101 , and an output end of the driving motor 102 passes through the mixing box 101 and is fixed to one end of the rotating rod 103 .

[0044] More specifically, when the driving motor 102 is in operation, its output end drives the rotating rod 103 to rotate, so that the stirring rod 104 on the side stirs the raw materials in the mixing box 101 to fully mix them.

[0045] Furthermore, a feeding interface 202 is provided on the side of the feeding cylinder 201 .

[0046] More specifically, the feeding interface 202 is located at the bottom position on the side of the material conveying cylinder 201, so that after the limiting cover plate 208 moves downward and the space inside the material conveying cylinder 201 is adjusted, it can still convey the preparation raw materials into the material conveying cylinder 201.

[0047] Furthermore, a scale 205 is provided on the side of the lifting rod 204.

[0048] More specifically, on the side of the lifting rod 204, a scale 205 is arranged along its length direction, and the scale values gradually decrease from the bottom end of the lifting rod 204 upward. The maximum value at the bottom end of the lifting rod 204 is the maximum capacity inside the material conveying cylinder 201, while the minimum value at the top end of the lifting rod 204 is the minimum value of the space inside the material conveying cylinder 201. Thus, when the lifting rod 204 descends, the limiting cover plate 208 also descends, and the remaining capacity space inside the material conveying cylinder 201 can be understood by observing the scale 205.

[0049] Furthermore, on the side of the lifting rod 204, a tooth profile groove 2041 is opened along its length direction. A control groove 2031 is opened on the side of the convex block 203, and the control groove 2031 penetrates through the convex block 203. At the same time, a control gear 2032 is rotatably connected in the control groove 2031, and the control gear 2032 meshes in the tooth profile groove 2041.

[0050] More specifically, by moving the control gear 2032 up and down, under the acting force of the meshing between the control gear 2032 and the tooth profile groove 2041, the lifting rod 204 moves up and down to adjust the height of the limiting cover plate 208 inside the material conveying cylinder 201.

[0051] Furthermore, a threaded rod 214 is movably sleeved inside the linkage rod 207. One end of the threaded rod 214 penetrates through the limiting cover plate 208 and is fixed with a material conveying pressing plate 215. The limiting cover plate 208 and the material conveying pressing plate 215 are attached to the inner wall of the material conveying cylinder 201.

[0052] More specifically, when the threaded rod 214 moves up and down, it drives the material conveying pressing plate 215 to press the raw materials inside the cylinder downward, so as to input the raw materials into the mixing box 101 from the connection interface 105.

[0053] In addition, it should be further noted that rubber rings are fixed on the sides of the limiting cover plate 208 and the material conveying pressing plate 215. The rubber rings are attached to the inner wall of the material conveying cylinder 201 to increase the sealing performance of the connection part, thereby preventing the raw materials from leaking out through the gaps.

[0054] Further, a driving box 209 is fixed to the top of the linkage plate 206. A driving gear 210 and a rotating gear 211 are rotatably connected in the driving box 209. A transmission belt 212 is engaged with the sides of the two gears. At the same time, a threaded ring 213 is fixed inside the rotating gear 211, and the threaded ring 213 is threadedly connected to the side of the threaded rod 214.

[0055] More specifically, under the acting force of the meshing of the driving gear 210 and the rotating gear 211 with the transmission belt 212, after the driving gear 210 rotates, the transmission belt 212 is driven to make the rotating gear 211 rotate synchronously. When the rotating gear 211 rotates, under the acting force of the threaded connection between the internal threaded ring 213 and the side of the threaded rod 214, the threaded rod 214 drives the feeding pressing plate 215 to move up and down.

[0056] Further, a micro motor 216 is fixed to the top of the driving box 209. The output end of the micro motor 216 penetrates into the driving box 209 and is fixed on the driving gear 210.

[0057] More specifically, the output end of the micro motor 216 has the function of bidirectional rotation. When the micro motor 216 operates, its output end drives the driving gear 210 to rotate. Under the action of the forward and reverse rotation of the output end, the threaded rod 214 moves up and down.

[0058] Further, on the side of the threaded rod 214, a stable sliding groove 2141 is formed along its length direction. At the same time, a stable sliding block 2071 is fixed inside the linkage rod 207, and the stable sliding block 2071 is slidably connected in the stable sliding groove 2141.

[0059] More specifically, when the threaded rod 214 moves up and down, the stable sliding groove 2141 slides along the side of the stable sliding block 2071, improving the stability of the lifting of the threaded rod 214. At the same time, it avoids the effect that the threaded rod 214 rotates simultaneously when the threaded ring 213 rotates.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
