Description

Technical Field

[0001] This invention relates to the field of solid bubble degassing rods used for gas extraction in gas field development, and particularly to a solid bubble degassing rod manufacturing apparatus and method. Background Technology

[0002] During the extraction of natural gas, gaseous water vapor in the well liquefies into liquid water, forming a pool of liquid at the bottom of the well, which affects the production of natural gas. Therefore, a solid bubble degassing rod that can automatically release bubbles is used to contact the pool of liquid at the bottom of the well, generating a large amount of low-density foam, which is carried from the bottom of the well to the surface by the airflow, thus achieving the purpose of removing the pool of liquid at the bottom of the well.

[0003] In existing solid foam degassing rod preparation devices and methods, for example, Chinese patent publication CN113510961A discloses a self-foaming solid foam degassing ball mold and its preparation method. It utilizes an upper hemisphere mold, a lower hemisphere mold, and a stroke rod passing through the lower hemisphere mold to form a spherical solid foam degassing agent by casting. This device and method involve the fabrication of a mold, rather than the process of producing solid foam degassing agents. Furthermore, the mold involved in this patent is spherical, meaning that the produced solid foam degassing agent is spherical. During the continuous injection process into the oil pipe, blockage accidents are prone to occur, causing the spherical solid foam degassing agent to be unable to reach the liquid accumulation section, thus failing to contact the liquid and react, and failing to produce the beneficial effect of drainage and gas extraction.

[0004] Chinese patent publication CN203236737U discloses a foam bar pressing device, which includes a pressurizing device on support plates one and two for downwardly pressing the foam bar forming mold. This patent proposes a mold device for processing foam bars, but this device cannot process liquid foam bar raw materials; it can only compact and shape the finished solid foam bar.

[0005] Chinese patent publication CN208669285U discloses an on-site modification and processing device for bubble dewatering rods. The device involves a connected groove 1 and groove 2 forming a pressing cavity. During use, a conventional bubble dewatering rod, under the compression of a first and second shell, experiences an increase in density and a decrease in volume. Excess material squeezed from the rod is discharged from the pressing cavity, further reducing its size. Modifying a conventionally sized bubble dewatering rod into at least two rods reduces its volume and prevents blockage during descent, allowing it to smoothly enter the well bottom and react with the accumulated fluid. This patent primarily targets the secondary processing and cutting of finished solid bubble dewatering rods. However, solid bubble dewatering rods have poor plasticity; using extrusion deformation may cause them to crumble into fragments instead of maintaining their shape, and may only change their diameter and length.

[0006] In summary, the current equipment and methods for manufacturing solid foaming rods are imperfect, and there is a lack of equipment and methods for manufacturing solid foaming rods using liquid raw materials of solid foaming agents. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an apparatus and method for manufacturing solid foaming rods that can be formed using raw materials for making solid foaming agents.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a solid bubble bar manufacturing device, comprising a heating reaction constant temperature container, a cylindrical mold, a bullet mold, a pressurizing and pushing mechanism, and a conveying mechanism.

[0010] Furthermore, the cutter includes a saw blade, a saw blade drive motor for driving the saw blade, and a drive assembly for moving the saw blade and the saw blade drive motor along the radial direction of the formed solid bubble bar.

[0011] Furthermore, the saw blade is a chain saw blade, which is mounted on a saw blade mounting frame. The saw blade drive motor is connected to the drive wheel on the saw blade mounting frame via a transmission rod, thereby driving the chain saw blade to rotate.

[0012] Furthermore, the bottom of the saw blade mounting bracket is slidably connected to the slide rail, and the drive assembly is connected to the saw blade mounting bracket, driving the saw blade mounting bracket to slide along the slide rail.

[0013] Furthermore, the drive component is a hydraulic cylinder.

[0014] Furthermore, a waste collector is provided below the cutter.

[0015] Furthermore, the heating reaction thermostat container is equipped with a stirrer, a heating thermostat system, an infrared level gauge, and a temperature sensor.

[0016] Furthermore, the upper part of the heating reaction constant temperature container is provided with a foaming agent injection port and a curing agent injection port.

[0017] Furthermore, the lower outlet of the heating reaction thermostatic container is connected to an output pipe, the input port of the cylindrical mold is connected to an injection pipe, the output pipe and the injection pipe are connected by a universal joint, and the output pipe and / or the injection pipe are equipped with a switch valve.

[0018] Furthermore, the translation mechanism includes a linear guide rail and a support slider mounted on the bottom of the cylindrical mold and slidingly engaged with the linear guide rail. The cylindrical mold is connected to a transmission assembly, which controls the reciprocating motion of the cylindrical mold along the linear guide rail.

[0019] Furthermore, the transmission assembly includes a stepper motor, a drive shaft, and a gear mounted on the drive shaft, and the bottom of the cylindrical mold is provided with a flat rack that meshes with the gear along the direction of travel.

[0020] Furthermore, the cylindrical mold has axially spaced, equally spaced cooling channels at the bottom cross-section.

[0021] Furthermore, the bullet mold includes a bullet mold body, and the lifting mechanism includes a vertical support rod, a fixed bracket, and a second hydraulic cylinder. The bullet mold body is connected to the fixed bracket, and the fixed bracket is vertically mounted on the vertical support rod via the second hydraulic cylinder.

[0022] Furthermore, the piston of the pressurizing and pushing mechanism is connected to a push rod, which is connected to a hydraulic cylinder, and the hydraulic cylinder controls the push rod to drive the piston to reciprocate within the cylindrical mold.

[0023] Furthermore, the conveying mechanism includes a semi-circular trough and a conveyor belt, which are sequentially arranged on the side of the bullet mold away from the cylindrical mold.

[0024] A method for producing solid bubble rods using the above-mentioned solid bubble rod making apparatus includes the following steps: S1: Determine the volume V of the solid bubble decanter mold based on the size of the gas well tubing, and heat the solution to a predetermined temperature T1 by heating the reaction constant temperature container and maintain the constant temperature; S2: The cylindrical mold and the bullet mold are tightly fitted at the initial position X1 and Y1; S3: Open the pipeline switch through the control system, heat the reaction thermostat container to inject liquid into the cylindrical mold and bullet mold, determine the time T1 for complete injection into the mold based on the injection flow rate and mold volume, determine the liquid level change Δh through the infrared liquid level gauge of the heating reaction thermostat container, close the switch after injection, start the hydraulic cylinder one that controls the piston in the cylindrical mold, push the piston to compact the solution to the initial position X3 of the piston and then stop, determine the time T2 for complete solidification of the solution in the cylindrical mold and bullet mold; S4: The control system starts hydraulic cylinder one, retracts the push rod and piston to the designated position X4, and then starts the motor of the transmission component to drive the gear, which drives the cylindrical mold to move to the designated position X2, separating it from the bullet mold. The translation distance is the length of the bullet mold body. Hydraulic cylinder two starts the bullet mold and pushes the bullet mold body vertically upward to the designated position Y2. The translation distance is the diameter of the solid bubble bar cylindrical hollow mold body. S5: The transmission component drives the cylindrical mold to translate to the initial position X1, and starts the cutter and the matching hydraulic cylinder to cut the rocket-shaped solid bubble bar; when the hydraulic cylinder pushes the piston in the cylindrical mold to position X5, it stops, and starts the cutter and the matching hydraulic cylinder to cut the cylindrical solid bubble bar. The cutter completes the radial cutting of the solid bubble bar in time T3. S6: When the hydraulic cylinder is activated and pushes the piston to position X1, the solid bubble bar is completely pushed out of the cylindrical mold into the semi-circular groove; S7: The cylindrical mold returns to its initial position X1, the bullet mold returns to its initial position Y1, the push rod drives the piston back to its initial position X3, repeat steps S2-S6 to produce the Nth solid bubble bar. When the N+1th solid bubble bar is produced, the N+1th solid bubble bar is pushed into the semi-circular groove, and the Nth solid bubble bar is pushed onto the conveyor belt.

[0025] In summary, the present invention has the following beneficial effects: (1) Liquid foaming agent enters the mold and is formed by hydraulic extrusion.

[0038] The present invention will be further described in detail below with reference to the embodiments.

[0039] In practical implementation: such as Figure 1 As shown, a solid bubble bar manufacturing device includes a heating reaction thermostatic container 1, a cylindrical mold 2, a bullet mold 3, a pressurizing and pushing mechanism, and a conveying mechanism. The pressurizing and pushing mechanism is located at one end of the cylindrical mold 2, and the bullet mold 3 and the conveying mechanism are sequentially located at the other end of the cylindrical mold 2. An injection cavity is formed between the piston 27 of the pressurizing and pushing mechanism, the cylindrical mold 2, and the bullet mold 3. The heating reaction thermostatic container 1 is connected to the injection cavity and injects raw materials into the cylindrical mold 2 and the bullet mold 3. The pressurizing and pushing mechanism pressurizes the raw materials in the injection cavity to form solid bubble bars by the movement of the piston 27. The cylindrical mold 2 is connected to a translation mechanism, and the bullet mold 3 is connected to a lifting mechanism. After the bubble bar is formed, the translation mechanism drives the cylindrical mold 2 to separate from the bullet mold 3, the lifting mechanism drives the bullet mold 3 to move radially to avoid the solid bubble bar, and the pressurizing and pushing mechanism gradually pushes the solid bubble bar out of the cylindrical mold 2 to the conveying mechanism.

[0040] The cylindrical mold 2 reciprocates along the axial direction between X1 and X2, while the bullet mold 3 moves up and down along the radial direction between Y1 and Y2. When the cylindrical mold 2 is located at X1 and the bullet mold 3 is located at Y1, the liquid in the heated reaction constant temperature container 1 is introduced into the cylindrical mold 2 and the bullet mold 3, and pressure is applied to make the liquid fill the cylindrical mold 2 and the bullet mold 3 and solidify into a predetermined shape. When the bullet mold 3 moves to X2, the formed solid bubble bar is separated from the bullet mold 3, and when the bullet mold 3 moves to Y2, the solid bubble bar exposed in the cylindrical mold 2 at X1 is cut radially.

[0041] Among them, such as Figure 8 As shown, it also includes a cutter 11 located at the end of the cylindrical mold 2 near the bullet mold 3. The cutter 11 is configured to cut the ejected solid bubble bar from the end of the cylindrical mold 2 after the pressurized pushing mechanism pushes the formed solid bubble bar out of the cylindrical mold 2.

[0042] Solid bubble bar cutting can be performed using a wire cutter or a circular saw. The cutter 11 includes a saw blade 35, a saw blade drive motor 38 that drives the saw blade 35, and a drive assembly that moves the saw blade 35 and the saw blade drive motor 38 along the radial direction of the formed solid bubble bar. The saw blade 35 is a chain saw blade, mounted on a saw blade mounting frame. The saw blade drive motor 38 is connected to the drive wheel on the saw blade mounting frame via a transmission rod 39, driving the chain saw blade to rotate. The bottom of the saw blade mounting frame is slidably connected to a slide rail 36. The drive assembly is connected to the saw blade mounting frame, causing the saw blade mounting frame to slide along the slide rail 36. The drive assembly is a hydraulic cylinder 7.3.

[0043] In practical implementation, the cutter 11 includes a chain saw blade, a hydraulic cylinder 3.3, a slide rail 36, a pull rod 37, a drive motor 38, and a transmission rod 39. The chain saw blade is vertically mounted on the worktable 10. The slide rail 36 is horizontally placed and connected to the hydraulic cylinder 3.3. The hydraulic cylinder 3.3 is fixedly mounted on the worktable 10. The drive motor 38 transmits power to start the chain saw blade through the transmission rod 39. The hydraulic cylinder 3.3 controls the chain saw blade to move horizontally in the radial direction through the telescopic pull rod 37 to cut solid bubble bars. The sleeve 31 on the cutter 11 is nested and connected to the slide rail 36. The two slide rails 36 are horizontally placed and connected to the hydraulic cylinder 3.3. The hydraulic cylinder 3.3 is fixedly mounted on the worktable 10. The pull rod 37 and the transmission rod 39 are connected to the rotary joint 43 and fixed by a fixing pin.

[0044] In implementation, such as Figure 1 As shown, both the foaming agent and the solidifying agent are liquids, injected through the foaming agent injection port 22 and the curing agent injection port 23 at the top of the heating reaction thermostatic container 1. The heating reaction thermostatic container 1 is equipped with a stirrer 20, an infrared level gauge 17, and a temperature sensor 18. The infrared level gauge 17 determines the liquid level change to control the injection volume. The lower output port 24 of the heating reaction thermostatic container 1 is connected to the output pipe 15, and the input port of the cylindrical mold body 44 is connected to the injection pipe 29. The output pipe 15 and the injection pipe 29 are connected by a universal joint 16, and both the output pipe 15 and the injection pipe 29 are equipped with a switch valve 14, or a switch valve 14 is installed on either the output pipe 15 or the injection pipe 29, so that the liquid in the heating reaction thermostatic container 1 can enter the cylindrical mold 2.

[0045] The heating reaction constant temperature container 1 is connected and fixed to the base 21. The base 21 has a lifting function and can be adjusted to adapt to different working conditions. The heating reaction constant temperature container 1 is equipped with a heating constant temperature system 19. By injecting a liquid solvent containing defoaming agent and curing agent into the heating reaction constant temperature container 1 and stirring it evenly, the liquid solvent is heated to a certain temperature by the heating constant temperature system 19 and kept at a constant temperature. The bullet-shaped mold 3 is fitted to the discharge end of the cylindrical mold 2. The bullet-shaped mold 3 and the cylindrical mold 2 are sealed together at one end. The bullet-shaped mold 3 can be removed to remove the solid bubble bar or liquid solvent inside the cylindrical mold 2. The heating reaction constant temperature container 1 is connected to the cylindrical mold 2, and the liquid in the heating reaction constant temperature container 1 is input into the cylindrical mold 2 and the bullet-shaped mold 3. The cylindrical mold 2 is pressurized so that the liquid fills the cylindrical mold 2 and the bullet-shaped mold 3 and solidifies into a predetermined shape. The cutter 11 is used to cut the formed rocket-shaped and cylindrical solid bubble bar, producing two different shapes and specifications of solid bubble bar, cylindrical and rocket-shaped, to meet the actual needs of gas wells with different tubing string structures on site. Compared with spherical and other shaped solid bubble bar, it is less prone to jamming accidents during the bar deployment process, which greatly improves the success rate of drainage and gas production.

[0046] A linear guide rail 13 is also installed on the workbench 10. A support slider 25 that slides with the linear guide rail 13 is installed at the bottom of the cylindrical mold 2. The cylindrical mold body 44 is connected to a transmission assembly 8, which controls the reciprocating motion of the cylindrical mold 2 along the linear guide rail 13. The transmission assembly 8 includes a stepper motor 40, a transmission shaft 41, and a gear 42 mounted on the transmission shaft 41. A flat rack 26 that meshes with the gear 42 is provided at the bottom of the cylindrical mold 2 along the direction of travel.

[0047] like Figure 4 and Figure 6 As shown, the cylindrical mold body 44 has a smooth internal cylindrical surface milled by a milling cutter. Axially spaced cooling channels 30 are formed at the wall thickness of the bottom section of the cylindrical mold body 44. Multiple cooling channels 30 are arranged circumferentially. One end of each cooling channel 30 is a coolant inlet 46, which is sealed with a sealing nut 45. Injecting coolant into the cooling channels 30 is faster than natural cooling, improving the yield and adapting to different ambient temperatures, allowing the solution to completely solidify and form. Seven cooling channels 30 are spaced 45 degrees apart at the wall thickness of the cylindrical mold body 44. No cooling channels 30 are provided at the wall thickness directly above the central axis of the cylindrical mold body 44. Injection channels are provided at both ends directly above the central axis of the cylindrical mold body 44, with two holes drilled at equal intervals. A switch valve 14 is installed on the injection pipe 29. The cylindrical mold body 44 has an internal push rod 28 integrated with the hydraulic cylinder 7.1 hydraulic rod, and the push rod 28 is connected to the piston 27.

[0048] In implementation, such as Figure 1 , Figure 3and Figure 5 As shown, the cylindrical mold for solid bubble bar cutting needs to move during cutting. A linear guide rail 13 is installed on the worktable 10. A support slider 25 that slides with the linear guide rail 13 is installed at the bottom of the cylindrical mold 2, allowing the cylindrical mold 2 to slide on the worktable 10. Simultaneously, the cylindrical mold body 44 is connected to a transmission assembly 8, which controls the reciprocating motion of the cylindrical mold 2 along the linear guide rail 13. The linear guide rail 13 is laid on both sides of the worktable 10, with equidistant tapped holes directly above it. Four limiters 12 are installed at both ends along its length, and are bolted to the linear guide rail 13 to limit the horizontal displacement of the cylindrical mold 2. The transmission assembly 8 includes a stepper motor 40, a drive shaft 41, and a gear 42 mounted on the drive shaft 41. A flat rack 26 that meshes with the gear 42 is provided at the bottom of the cylindrical mold body 44 along the travel direction.

[0049] In practice, the piston 27 of the pressurizing and pushing mechanism is connected to a push rod 28, which is connected to a hydraulic cylinder 7.1. The hydraulic cylinder 7.1 controls the push rod 28 to drive the piston 27 to reciprocate within the cylindrical mold body 44. The hydraulic push rod 28 drives the piston 27 to pressurize the cylindrical mold 2, squeezing the solution injected from the inlet into the bullet mold body 33 to form the mold.

[0050] In implementation, such as Figure 7 As shown, the bullet mold 3 includes a bullet mold body 33. The lifting mechanism includes a vertical support rod 32, a fixed bracket 34, and a second hydraulic cylinder 7.2. The bullet mold body 33 is connected to the fixed bracket 34 and reinforced with reinforcing ribs. The fixed bracket 34 is vertically mounted on the vertical support rod 32 via the second hydraulic cylinder 7.2. A sleeve 31 is fixed to one side of the fixed bracket 34. Two sleeves 31 are fixed and nested onto the two vertical support rods 32 respectively. The hydraulic cylinder of the second hydraulic cylinder 7.2 is fixed to the vertical support rod 32 with bolts. The hydraulic rod of the second hydraulic cylinder 7.2 is connected and fixed to both ends of the fixed bracket 34. The vertical support rod 32 is a smooth cylinder connected to a linear guide rail 13.

[0051] To achieve efficient production through automated control, the bullet mold 3 has a semi-circular groove 4 and a conveyor belt 5 arranged sequentially on the side away from the cylindrical mold 2. The heating reaction thermostatic container 1, transmission assembly 8, hydraulic cylinder 1 7.1, hydraulic cylinder 2 7.2, and hydraulic cylinder 3 7.3 are connected to the control system 9, which can be configured using a control panel. The bottom of the cutter 11 has a waste collector 6 for collecting cutting waste.

[0052] A method for producing solid bubble rods using the above-mentioned solid bubble rod making apparatus includes the following steps: S1: Determine the volume V of the solid bubble decanter mold according to the size of the gas well tubing, and heat the solution to a predetermined temperature T1 by heating the reaction constant temperature container 1 and maintain the constant temperature; S2: The cylindrical mold 2 and the bullet mold 3 are tightly fitted at the initial position X1 and Y1 respectively; S3: Open the pipeline switch through the control system 9, heat the reaction constant temperature container 1 to inject liquid into the cylindrical mold 2 and the bullet mold 3, determine the time T1 for complete injection into the mold according to the injection flow rate and the mold volume, determine the liquid level change Δh through the infrared liquid level gauge 17 of the heating reaction constant temperature container 1, close the switch after injection, start the hydraulic cylinder 7.1 that controls the piston 27 in the cylindrical mold 2, push rod 28 pushes the piston 27 to compact the solution to the initial position X3 of the piston 27 and then stop, determine the time T2 for complete solidification of the solution in the cylindrical mold 2 and the bullet mold 3; S4: The hydraulic cylinder 7.1 is activated by the control system 9. After the push rod 28 and piston 27 are retracted to the designated position X4, the motor of the transmission component 8 is activated to drive the gear 42, which drives the cylindrical mold 2 to translate to the designated position X2 and separate it from the bullet mold 3. The translation distance is the length of the bullet mold body 33. The hydraulic cylinder 7.2 of the bullet mold 3 is activated to push the bullet mold body 33 vertically upward to the designated position Y2. The translation distance is the diameter of the solid bubble bar cylindrical hollow mold body. S5: The transmission component 8 drives the cylindrical mold 2 to translate to the initial position X1, and starts the cutter 11 and the matching hydraulic cylinder 7.3 to cut the rocket-shaped solid bubble bar; when the hydraulic cylinder 7.1 pushes the piston 27 in the cylindrical mold 2 to the position X5 and stops, the cutter 11 and the matching hydraulic cylinder 7.3 start to cut the cylindrical solid bubble bar, and the radial cutting of the solid bubble bar by the cutter 11 is completed in time T3. S6: When the hydraulic cylinder 7.1 is activated and the piston 27 is pushed to position X1, the solid bubble bar is completely pushed out of the cylindrical mold 2 into the semi-circular groove 4; S7: The cylindrical mold 2 returns to its initial position X1, the bullet mold 3 returns to its initial position Y1, the push rod 28 drives the piston 27 to return to its initial position X3, repeat steps S2-S6 to make the Nth solid bubble bar. When the N+1th solid bubble bar is made, the N+1th solid bubble bar is pushed into the semi-circular groove 4, and the Nth solid bubble bar is pushed onto the conveyor belt 5.
