Description

Technical Field

[0001] This invention relates to the field of reaction vessels, and more specifically, to a production apparatus and method for cementing drag-reducing agents. Background Technology

[0002] As a chemical additive widely used in petroleum, chemical and other fields, drag-reducing agents have extremely high requirements for the mixing efficiency, reaction uniformity and production safety of reaction equipment during their production process.

[0003] Traditional reactor stirring methods mainly rely on the mechanical stirring action of agitators. The stirring efficiency is limited by the agitator's rotation speed and blade design. For high-viscosity drag-reducing agent raw materials, relying solely on the stirring action of the agitator is insufficient to achieve the desired mixing effect. Therefore, we propose a production device and method for cementing drag-reducing agents. Summary of the Invention

[0004] This invention provides a production apparatus and method for cementing drag-reducing agents, solving the technical problem in related technologies that it is difficult to achieve the ideal mixing effect for drag-reducing agent raw materials with high viscosity by simply relying on the stirring action of a stirrer.

[0005] The first aspect of the present invention provides a cementing drag-reducing agent production device, comprising: a production reactor, an inner reaction tank coaxially nested inside the production reactor, and four stirring mechanisms evenly distributed and fixed on the top of the production reactor. The four stirring mechanisms are rotationally symmetrically distributed along the axis of the production reactor, and the lifting end of each stirring mechanism is fixedly connected to the outer wall of the inner reaction tank to form a four-way dynamic lifting support structure. Each stirring mechanism includes an external equipment box, a winch motor assembly, a load cell, a stranding reel, and a hoisting cable assembly. The external equipment box is fixedly installed on the top outside of the production reactor, and the winch motor assembly and the load cell are both fixedly installed inside the external equipment box. The shaft end of the winch motor assembly is connected to the winch reel for drive. The winch reel is wound with a lifting cable. The free end of the lifting cable passes through the top of the production reactor and is fixedly connected to the top of the inner reactor, forming a four-way synchronous lifting drive unit. The detection end of the weighing sensor is connected to a weighing rope, and the free end of the weighing rope also passes through the top of the production reactor and is fixedly connected to the top of the inner reaction tank to form an independent weight detection unit. When the inner reaction tank is stirring the drag-reducing agent raw materials, the lifting cable is simultaneously loosened by the four winch motor assemblies, so that the inner reaction tank is in a taut and suspended state under its own weight. At this time, the weighing sensor detects the total weight of the inner reaction tank in real time through the weighing rope. By controlling the four winch motor assemblies to alternately tighten the lifting tank cable, the inner tank of the reaction vessel is alternately tilted in different directions during the stirring process, forming a dynamic stirring effect.

[0006] Furthermore, the stranding reel is divided into two parts, each of which is wound with a lifting cable. These two lifting cables form a group, and there are a total of four groups. The four groups of weight-measuring lifting cables are located on both sides of the weight-measuring lifting cable.

[0007] Furthermore, a 10cm gap is maintained between the inner wall of the production reactor and the outer wall of the inner reaction vessel. A rubber gasket is fixedly installed on the top outer ring of the inner reaction vessel, and the rubber gasket is elastic. The top of the rubber gasket is fixed to the top of the inner wall of the production reactor.

[0008] Furthermore, the production reactor includes an upper outer tank and a lower outer tank, which together form an assembly structure. A valve and a flexible bellows are installed between the bottom center of the inner reaction tank and the center of the lower outer tank.

[0009] Furthermore, multiple feed hoses are fixedly installed on the upper wall of the inner reaction vessel, and multiple feeding flanges are also installed on the upper wall of the production reactor. Each feeding flange corresponds to one of the multiple feed hoses and they are interconnected.

[0010] Furthermore, several lifting cables are tightly attached to the outside of one end of the inner reaction vessel to detect changes in the lifting cables under load and prevent the lifting cables from being stretched. The data receiving end of the thin-film pressure sensor is equipped with a sensor data box, which is fixedly installed in the peripheral box.

[0011] Furthermore, an outer ring box is fixedly installed on the outer ring of the lower outer tank, and an array of electromagnets is arranged inside the outer ring box. All electromagnets are controlled by the system.

[0012] Furthermore, a magnetic ring is fixedly installed on the outer wall of the inner reaction vessel. The height of the magnetic ring is the same as the height of the electromagnet, and the width of the magnetic ring is greater than the width of the electromagnet. The magnetic ring and the electromagnet repel each other. The operation of the electromagnet pushes the magnetic ring to control the swing of the inner reaction vessel.

[0013] Furthermore, a position sensor is installed in the gap between two adjacent electromagnets, and several position sensors are used to detect the swing amplitude of the reaction vessel in different directions.

[0014] A second aspect of the present invention provides a method for producing a drag-reducing agent for cementing, comprising the following steps: S1. The inner reaction vessel is suspended inside the production reactor by the synchronous operation of the winch motor assemblies of the four stirring mechanisms. S2. Inject materials into the reaction tank through the feeding flange and feeding hose, and monitor the injected weight in real time through a weighing sensor. S3. Start the agitator to stir, and at the same time the control system controls the four winch motor assemblies to alternately raise and lower the tank cable, so that the reaction tank tilts in multiple directions to form dynamic stirring. S4. During the mixing process, the weight change of the material is continuously monitored by a weighing sensor, and the safety status of the hoisting cable is monitored by a membrane pressure sensor. S5. After the reaction is complete, the material is discharged through the valve and flexible bellows at the bottom of the outer lower tank.

[0015] The beneficial effects of this invention are as follows: This invention sets up four stirring mechanisms that are rotationally symmetrically distributed along the axis of the production reactor to form a four-way dynamic hoisting support structure, which realizes the suspension installation of the inner reactor. The weighing sensor is connected to the inner reactor through an independent weighing rope, which can detect the total weight of the inner reactor in real time when it is suspended, thus realizing precise control of the feeding amount and solving the problem that traditional fixed reactors cannot monitor the weight of the inner reactor in real time. By controlling the four winch motor assemblies to alternately tighten the tank hoisting cable, the inner reaction tank is tilted in multiple directions during the stirring process, forming a dynamic stirring effect. This dynamic stirring method can change the flow path of the material in the inner reaction tank, break the traditional fixed flow pattern, effectively prevent the material from settling at the bottom, and improve the mixing uniformity and reaction efficiency.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1-7 As shown, a cementing drag-reducing agent production device includes: a production reactor 11, a reaction inner tank 15 coaxially nested inside the production reactor 11, and four stirring mechanisms 2 evenly distributed and fixed on the top of the production reactor 11. The four stirring mechanisms 2 are rotationally symmetrically distributed along the axis of the production reactor 11, and the lifting end of each stirring mechanism 2 is fixedly connected to the outer wall of the reaction inner tank 15 to form a four-way dynamic lifting support structure. Each stirring mechanism 2 includes an external box 21, a winch motor assembly 23, a weighing sensor 26, a strand spool 24, and a hoisting cable assembly. The external box 21 is fixedly installed on the top outside of the production reactor 11, and the winch motor assembly 23 and the weighing sensor 26 are both fixedly installed inside the external box 21. The shaft end of the winch motor assembly 23 is driven to be connected to the winch reel 24. The winch reel 24 is wound with a lifting cable 25. The free end of the lifting cable 25 passes through the top of the production reactor 11 and is fixedly connected to the top of the inner reaction tank 15, forming a four-way synchronous lifting drive unit. The detection end of the weighing sensor 26 is connected to a weighing rope 27. The free end of the weighing rope 27 also passes through the top of the production reactor 11 and is fixedly connected to the top of the inner reaction tank 15 to form an independent weight detection unit. When the inner reaction tank 15 is stirring the drag-reducing agent raw material, the four winch motor assemblies 23 simultaneously loosen the tank hoisting cable 25, so that the inner reaction tank 15 is in a taut and suspended state under its own weight. At this time, the weighing sensor 26 detects the total weight of the inner reaction tank 15 in real time through the weighing rope 27. By controlling the four winch motor assemblies 23 to alternately tighten the lifting tank cable 25, the inner reaction tank 15 is alternately tilted in different directions during the stirring process, forming a dynamic stirring effect.

[0020] The strand spool 24 is divided into two parts, each of which is wound with a lifting cable 25. The two lifting cables 25 form a group, and there are a total of four groups. The four groups of weighing lifting ropes 27 are located on both sides of the weighing lifting rope 27.

[0021] A 10cm gap is maintained between the inner wall of the production reactor 11 and the outer wall of the inner reaction vessel 15. A rubber gasket 29 is fixedly installed on the top outer ring of the inner reaction vessel 15. The rubber gasket 29 is elastic and the top of the rubber gasket 29 is fixed to the top of the inner wall of the production reactor 11.

[0022] The production reactor 11 includes an upper outer tank 12 and a lower outer tank 13. The upper outer tank 12 and the lower outer tank 13 together form an assembly structure. A valve and a flexible bellows are provided between the bottom center of the inner reaction tank 15 and the center of the lower outer tank 13.

[0023] Multiple feed hoses 22 are fixedly installed on the upper wall of the inner reaction vessel 15, and multiple feed flanges 14 are also installed on the upper wall of the production reactor 11. Each feed flange 14 corresponds to a feed hose 22 and they are interconnected.

[0024] Several tank lifting cables 25 are tightly attached to the outside of one end of the inner reaction vessel 15 with a thin film pressure sensor 201 to detect the change of the tank lifting cables 25 under weighing and to prevent the tank lifting cables 25 from being stretched. The data receiving end of the thin film pressure sensor 201 is provided with a sensor data box 28, and the sensor data box 28 is fixedly installed in the peripheral box 21.

[0025] The outer ring box 31 is fixedly installed on the outer ring of the lower outer tank 13. The outer ring box 31 contains an array of electromagnets 33, and all electromagnets 33 are controlled by the system.

[0026] A magnetic ring 32 is fixedly installed on the outer wall of the inner reaction vessel 15. The height of the magnetic ring 32 is the same as the height of the electromagnet 33, and the width of the magnetic ring 32 is greater than the width of the electromagnet 33. The magnetic ring 32 and the electromagnet 33 repel each other. The operation of the electromagnet 33 pushes the magnetic ring 32 to control the swing of the inner reaction vessel 15.

[0027] A position sensor 34 is installed in the gap between two adjacent electromagnets 33. Several position sensors 34 are used to detect the swing amplitude of the inner reaction vessel 15 in different directions.

[0028] The key is that a four-way dynamic hoisting support structure enables the internal reaction tank to tilt in a controllable alternating manner during the stirring process, thereby creating a dynamic stirring effect and significantly improving mixing efficiency and uniformity.

[0029] Overall structure and static suspension status: The main structure of the device includes a production reactor 11, inside which a reaction vessel 15 is coaxially nested. The reaction vessel 15 is not fixedly installed, but is suspended inside the production reactor 11 by four rotationally symmetrical stirring mechanisms 2 (spaced 90 degrees apart along the axis).

[0030] In the initial state or during normal stirring, the winch motor assemblies 23 in the four stirring mechanisms 2 operate synchronously, slackening the tank suspension cables 25 at the same rate and length. At this time, the inner reaction tank 15 relies entirely on its own weight to taut the four tank suspension cables 25, forming a stable suspension system. In this state, the vertical position of the inner reaction tank 15 is determined by the four cables, and its center of gravity is located on the axis.

[0031] When weighing is required, the weighing sensor 26 in each stirring mechanism 2 is connected to the inner reaction vessel 15 via an independent weighing rope 27. Since the lifting cables 25 are in a relaxed load-bearing state, the total weight of the inner reaction vessel 15 is almost entirely distributed across the four weighing ropes 27. The sum of the tensions monitored in real time by the four weighing sensors 26 is the total weight of the inner reaction vessel 15 and its internal materials. .

[0032] The formula is expressed as: ; in, This is the reading of the i-th weighing sensor 26. This enables online dynamic monitoring of the material weight during stirring, facilitating precise control of the reaction process.

[0033] The working principle of dynamic stirring effect: When enhanced mixing is required, the system controls the four winch motor assemblies 23 to alternately tighten or loosen the tank cable 25 according to a preset program.

[0034] Core logic: By asymmetrically changing the length of the four cables, the suspension plane of the inner reaction vessel 15 is tilted, thereby changing the flow pattern of the fluid inside the vessel.

[0035] Workflow Analysis: Initial equilibrium state: All four winch motors are in the relaxed state, and the inner reaction tank 15 is horizontally suspended.

[0036] Directional tilt (e.g., tilting in the positive X-axis direction): The winch motor assembly 23 (e.g., A stirring mechanism 2) located in the positive X-axis direction begins to tighten its corresponding tank cable 25, shortening the effective length ΔL of the cable.

[0037] At the same time, the winch motor assembly 23 (e.g., C-stirring mechanism 2) located in the negative X-axis direction simultaneously loosens its corresponding hoisting cable 25, increasing the effective length ΔL of the cable.

[0038] The two winch motor assemblies 23 (B and D) located in the Y-axis direction remain stationary or are finely adjusted to maintain stability.

[0039] Result: The positive X-axis side of the reaction tank 15 was raised, while the negative X-axis side was lowered, resulting in a tilt angle θ around the Y-axis. The relationship between the tilt angle θ and the change in cable length ΔL and the tank radius R can be approximated as follows: ; Where D is the distance between the two suspension points in the X direction. Typically, to ensure stability and avoid damage to the flexible connector, the tilt angle θ is controlled within a small range (e.g., 3 to 8).

[0040] Direction switching: After maintaining the tilted state for a period of time, the system begins to switch directions.

[0041] For example, to switch to tilting in the positive Y-axis direction, tighten the cable of stirring mechanism 2 (B), loosen the cable of stirring mechanism 2 (D), and simultaneously restore A and C to their balanced lengths.

[0042] By continuously or incrementally switching the tilt direction (such as X positive → Y positive → X negative → Y negative, or more complex combinations of trajectories), the bottom of the inner reaction vessel 15 will trace an approximately circular or square trajectory on the horizontal plane. This movement will generate strong radial and tangential convection in the material inside the vessel, effectively disrupting any "cylindrical rotation" dead zones that the material may form, and enhancing the mixing, heat transfer, and mass transfer processes.

[0043] Auxiliary and security modules: Thin-film pressure sensor 201: Attached to one end of the lifting cable 25 near the inner reaction vessel 15. During weighing, it detects minute deformations in the cable caused by stress. If the cable creeps due to prolonged use or is accidentally stretched, its pressure value will drift, and the system can issue an early warning to prevent safety accidents caused by cable failure.

[0044] Electromagnetic oscillation auxiliary system: When more precise or higher frequency oscillations are required, electromagnet 33 can be activated. The array of electromagnets 33 inside the outer ring box 31 is energized and de-energized in a controlled manner.

[0045] By controlling the electromagnet 33 to generate a magnetic field in a specific direction, a repulsive force is produced between the electromagnet 33 and the magnetic ring 32 on the outer wall of the reaction vessel 15, thereby causing the vessel to oscillate slightly. This can serve as a powerful supplement to cable-driven systems, and is particularly suitable for applications requiring high-frequency, low-amplitude vibrations, helping to break up bubbles or prevent powder agglomeration.

[0046] Position sensor 34 monitors the sway amplitude of the inner reaction vessel 15 in different directions in real time, forming a closed-loop feedback control. For example, the sensor detects that the current sway amplitude is... , with target swing By comparison, the system adjusts the current intensity I of electromagnet 33 using a PID (proportional-integral-derivative) algorithm, thereby precisely controlling the magnetic force. This makes the swing amplitude approach the target value.

[0047] The four-way dynamic hoisting structure allows the inner reaction vessel 15 to tilt alternately, breaking the traditional single flow field mode in a fixed stirred tank where the fluid is driven solely by the agitator. This dynamic stirring effect effectively eliminates dead zones and enhances both macroscopic and microscopic mixing of materials. This is particularly important for the production of high-viscosity drag-reducing agents, significantly shortening the production cycle and ensuring high consistency in product quality between batches. Using an independent weighing sensor 26 and a weighing rope 27, the total weight of the materials inside the reaction vessel 15 can be measured in real time and accurately without interference from stirring vibrations and cable drives when the inner reaction vessel 15 is suspended. This provides key data for precise control of the reaction process (such as automatic feeding according to the formula and monitoring the reaction conversion rate), improving the level of automation and process stability of production.
