Description

Technical Field

[0001] This invention relates to the field of polymer injection skid-mounted equipment technology, and in particular to a rapid dispersion and dissolution skid-mounted equipment for offshore oil fields. Background Technology

[0002] In the process of offshore oilfield development, crude oil usually needs to be effectively processed, including dehydration, thickening, and pour point reduction, in order to improve oil quality and transportation efficiency. Among these processes, polymer injection is of great significance in offshore oilfield development, as it can significantly improve reservoir recovery. However, in the process of applying polymers to oilfields, polymer dissolution is a critical step, which requires ensuring that polymer molecules are uniformly dispersed into water molecules to form a completely dissolved molecular dispersion system. By using the curing tank built into the dispersion and dissolution skid-mounted equipment, the polymer and water are stirred and cured under specific temperature and pressure conditions, thereby accelerating the dispersion process of polymer molecules. This method enables the polymer to be more uniformly dispersed in water, improving the polymer's dissolution efficiency and utilization rate. Therefore, it can effectively enhance the effect of polymer injection in offshore oil fields, further increasing the comprehensive recovery rate and economic benefits of the oil fields.

[0003] A single-well polymer dispersion, dissolution, mixing, and injection skid-mounted equipment with announcement number CN118855438A has solved the problems of insufficient dissolution, the generation of "fish eyes" (undissolved polymer clusters), and bubbles. This addresses the drawbacks of prolonged curing time and low efficiency in the curing tank, requiring more curing tanks and resulting in higher investment and larger footprint for surface equipment. However, similar structures still have many shortcomings in practical use. For example, traditional dispersion and dissolution skid-mounted equipment typically uses a single stirring method, mixing polymer and water only in a limited direction, making it difficult to achieve multi-dimensional and all-round stirring effects. This leads to uneven polymer dispersion in the solution and the tendency for localized displacement, failing to achieve the desired dissolution effect and seriously affecting subsequent oilfield production rates.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a skid-mounted device for rapid dispersion and dissolution in offshore oil fields. This device addresses the problem that using a single stirring method can only mix polymers and water in a limited direction, making it difficult to achieve a multi-dimensional and all-round stirring effect. This results in uneven dispersion of the polymer in the solution and the easy occurrence of local displacement, failing to achieve the ideal dissolution effect and seriously affecting the subsequent oil field production rate.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows: A skid-mounted rapid dispersion and dissolution device for offshore oil fields includes a protective housing, three rotary telescopic mechanisms and a drive mechanism, and also includes a first dispersion tank, a second dispersion tank and a third dispersion tank fixedly installed inside the protective housing. It also includes three adjusting mechanisms rotatably installed on the tops of the first dispersion tank, the second dispersion tank and the third dispersion tank respectively. The first dispersion tank, the second dispersion tank and the third dispersion tank are connected through valve pipes. A stirring tank is fixedly installed on the top wall inside each of the first dispersion tank, the second dispersion tank and the third dispersion tank. The three rotary telescopic mechanisms are respectively fixedly installed on the top of the first dispersion tank, the second dispersion tank, and the third dispersion tank, and the three rotary telescopic mechanisms extend into the mixing tank inside the first dispersion tank, the second dispersion tank, and the third dispersion tank, respectively. The extension ends of the three rotary telescopic mechanisms are fixedly installed with grinding tanks through eccentric brackets, and the grinding tanks are movably installed inside the mixing tanks; the three rotary telescopic mechanisms are connected by a drive mechanism. The drive mechanism simultaneously drives three rotary telescopic mechanisms to operate synchronously. These three synchronously operating rotary telescopic mechanisms rotate and move vertically in response to the interior of the first, second, and third dispersion tanks, and cooperate with the stirring tank to agitate the polymer in the corresponding dispersion tank in the Y-axis direction, thus ensuring sufficient dispersion of the polymer. At the same time, the three synchronously operating rotary telescopic mechanisms drive the corresponding connected grinding tanks to rotate eccentrically through eccentric supports. When the grinding tanks rotate eccentrically, they cooperate with the inner wall of the stirring tank to grind and disperse the agglomerated polymer.

[0007] Preferably, the rotary telescopic mechanism comprises a mounting frame, an adjusting shaft arm, a linkage shaft, a universal coupling, a threaded rod, a stirring rod, and a stirring paddle. A threaded guide sleeve is fixedly installed at the bottom of one side of the mounting frame. The adjusting shaft arm is rotatably installed at the top of one side of the mounting frame. The linkage shaft is movably connected to the adjusting shaft arm via an assembly bolt. One end of the linkage shaft is movably connected to the threaded rod via a universal coupling. The threaded rod's threads penetrate the threaded guide sleeve. The stirring rod is fixedly installed at the bottom end of the threaded rod, and the stirring paddle is fixedly installed at the bottom end of the stirring rod.

[0008] Preferably, the adjusting shaft arm consists of a sliding groove rod, a lead screw, and a threaded sleeve seat. One end of the sliding groove rod has a spline hole, the lead screw is rotatably installed inside the sliding groove rod, and one end of the lead screw extends to the outside of the sliding groove rod. The threaded sleeve seat is threaded onto the outside of the lead screw, and an assembly bolt is fixedly installed on the front of the threaded sleeve seat.

[0009] Preferably, two sets of eccentric supports are fixedly sleeved on the outer side of the stirring rod, and the outer sides of the two sets of eccentric supports are fixedly installed on the inner wall of the grinding barrel.

[0010] Preferably, the drive mechanism consists of a drive motor and a drive rod. The drive motor is fixedly mounted on the mounting bracket at the top of the third dispersion tank. One end of the drive rod is fixedly connected to the output end of the drive motor, and the drive rod passes through the three mounting brackets and is splinedly engaged with one end of each of the three adjusting shaft arms.

[0011] Preferably, the drive rod consists of two shafts and three splined rods, with the three splined rods fixedly connected by the two shafts, and each splined rod engaging with the corresponding splined hole of the adjusting shaft arm.

[0012] Preferably, the first dispersion tank is equipped with an adjustable overflow weir, and four baffles are rotatably mounted on the outside of the mixing tank via shafts, and the four baffles are distributed in a ring array around the outside of the mixing tank.

[0013] Preferably, the adjustment mechanism consists of a toothed ring, three bevel gears, a screw sleeve, a screw rod, a drive gear, and a servo motor. An inner tooth sleeve is fixedly installed on the inner wall of the toothed ring. The three bevel gears are arranged in a ring array around the outer side of the toothed ring and are meshed with the toothed ring. A screw sleeve is fixedly installed at the bottom of each of the three bevel gears. The screw rod is threaded through the inside of the screw sleeve, and the bottom end of the screw rod is rotatably connected to an adjustable overflow weir via a turntable. The inner side of the toothed ring is meshed with the drive gear through an inner sleeve, and the top of the drive gear is fixedly connected to the output end of the servo motor.

[0014] Preferably, a side box is fixedly installed on one side of the protective enclosure, a PLC control cabinet is fixedly installed inside the side box, and a delivery pump is fixedly installed on the side of the side box away from the PLC control cabinet. The input end of the delivery pump is connected to an interface seat through a pipe, and the output end of the delivery pump is connected to the top of the first dispersion tank through a pipe.

[0015] The beneficial effects of this invention are: The technical solution of this invention, through the coordinated control of the drive mechanism, enables three rotating and telescopic mechanisms to work synchronously. These three synchronously operating rotating and telescopic mechanisms disperse and dissolve the polymer and water inside the first, second, and third dispersion tanks, respectively. Simultaneously, the rotating and telescopic mechanisms, through an eccentric support, drive the grinding barrel to rotate eccentrically while simultaneously moving vertically back and forth, thereby grinding and dispersing the agglomerated polymer. The synergistic effect of the grinding barrel enhancing the uniform dispersion of the polymer and the telescopic movement of the rotating and telescopic mechanisms adjusting the turbulence direction and increasing shear force achieves a rapid, efficient, and uniform polymer dissolution effect, greatly shortening the dissolution time and improving production efficiency. When the stirring paddle in the rotary telescopic mechanism moves into the mixing tank, it generates agitation in the Y-axis direction inside the mixing tank. The polymer and water are lifted in the Y-axis direction by the lifting action of the stirring paddle. When they rise to the top wall of the mixing tank, they are subjected to collision shear force, which breaks down the polymer molecular aggregation, achieves initial dispersion and dissolution, and forms fluid circulation. When the agitator in the rotary telescopic mechanism extends and retracts to the lower position, it creates a disturbed polymer flow within the dispersion tank. The flowing polymer diffuses to the outside of the mixing tank, disturbing the baffle plate and driving it to rotate. The polymer flows along the X-axis through the rotating baffle plate. The alternating flow direction creates continuous convective impact, breaking up polymer molecule agglomeration, improving dispersion efficiency, reducing viscosity loss, and ensuring that the agglomerated polymer is fully dispersed. The eccentrically rotating grinding barrel comes into intermittent contact with the mixing barrel. When the grinding barrel comes into contact with the mixing barrel, it can grind and disperse the agglomerated polymer circulating inside the mixing barrel, thereby achieving efficient dispersion and grinding of the polymer and achieving a uniform and fine effect. The reciprocating flow along the Y and X axes generates continuous shearing force and convection impact, which, combined with the grinding barrel's grinding and dispersing effect on the agglomerated polymer, effectively avoids the problems of local displacement and uneven dispersion in traditional dispersion and dissolution processes, thereby improving the overall quality of polymer dissolution.

Detailed Implementation

[0018] The following will be combined with the appendix Figure 1 To be continued Figure 13 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] A skid-mounted rapid dispersion and dissolution device for offshore oil fields includes a protective housing 1, three rotating and telescopic mechanisms 5 and a drive mechanism 6, and also includes a first dispersion tank 2, a second dispersion tank 3 and a third dispersion tank 4 fixedly installed inside the protective housing 1. It also includes three adjusting mechanisms 7 rotatably installed on the tops of the first dispersion tank 2, the second dispersion tank 3 and the third dispersion tank 4 respectively. The first dispersion tank 2, the second dispersion tank 3 and the third dispersion tank 4 are connected by valve pipes. A stirring tank 201 is fixedly installed on the top wall inside each of the first dispersion tank 2, the second dispersion tank 3 and the third dispersion tank 4. It should be noted that the protective housing 1 provides a safe and sealed working environment, ensuring that the operation of the equipment is not affected by the humid environment; the three rotating telescopic mechanisms 5, controlled by the drive mechanism 6, can rotate and move vertically synchronously inside the dispersion tank, effectively promoting the dispersion of the polymer in the mixing tank 201; the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4 are connected by valve pipes to form a whole. The dispersed polymer is transported from the first dispersion tank 2 to the second dispersion tank 3, further dispersed in the second dispersion tank 3, and then transported to the third dispersion tank 4 for complete dispersion; the three adjusting mechanisms 7 correspondingly adjust the position of the adjustable overflow weir 202, facilitating the adjustment of the overflow height. Three rotary telescopic mechanisms 5 are fixedly installed on the top of the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4, respectively. The three rotary telescopic mechanisms 5 extend into the mixing tank 201 inside the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4, respectively. The extended ends of the three rotary telescopic mechanisms 5 are fixedly installed with a grinding tank 203 through an eccentric bracket 2031, and the grinding tank 203 is movably installed inside the mixing tank 201. The three rotary telescopic mechanisms 5 are connected by a drive mechanism 6. The three rotary telescopic mechanisms 5 drive the grinding barrels 203 inside the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4 to generate eccentric rotation, which, in conjunction with the stirring barrel 201, further grinds the agglomerated polymer to achieve the ideal dispersion effect. The drive mechanism 6 simultaneously drives three rotary telescopic mechanisms 5 to operate synchronously. The three rotary telescopic mechanisms 5 rotate and move vertically inside the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4, respectively, and cooperate with the stirring tank 201 to stir the polymer in the corresponding dispersion tank in the Y-axis direction, so that the polymer is fully dispersed. At the same time, the three rotary telescopic mechanisms 5 drive the corresponding connected grinding tank 203 to rotate eccentrically through the eccentric bracket 2031. When the grinding tank 203 rotates eccentrically, it cooperates with the inner wall of the stirring tank 201 to grind and disperse the agglomerated polymer. It should be noted that the drive mechanism 6 simultaneously drives the three rotary telescopic mechanisms 5 to rotate and disperse while simultaneously telescopically moving, and the rotary telescopic mechanisms 5 drive the grinding barrel 203 to generate eccentric rotation through the eccentric bracket 2031. When the stirring paddle 507 in the rotary telescopic mechanism 5 extends and retracts into the mixing tank 201, the stirring paddle 507 generates Y-axis agitation inside the mixing tank 201. The polymer and water are lifted in the Y-axis direction by the lifting action of the stirring paddle 507. When the polymer rises to the top wall of the mixing tank 201, it undergoes collision shear force, which breaks down the polymer molecular aggregation. The collided polymer forms an internal circulation flow inside the mixing tank 201, which facilitates subsequent grinding and dispersion work. When the stirring paddle 507 in the rotary telescopic mechanism 5 telescopically moves downward, the stirring paddle 507 creates a disturbed polymer flow in the dispersion tank. The flowing polymer diffuses to the outside of the stirring tank 201 and disturbs the baffle plate 204, driving the baffle plate 204 to rotate. The polymer flows in the X-axis direction through the rotating baffle plate 204. The reciprocating flow in the Y-axis and X-axis directions generates continuous shear force and convection impact, which breaks down polymer molecule aggregation, improves dispersion efficiency, reduces viscosity loss, and allows the polymer to be fully dispersed and dissolved. The eccentrically rotating grinding barrel 203 is in intermittent contact with the stirring barrel 201. When the grinding barrel 203 is in contact with the stirring barrel 201, it can grind and disperse the agglomerated polymer circulating inside the stirring barrel 201, thereby achieving efficient dispersion and grinding of the polymer and achieving a uniform and fine effect.

[0020] like Figures 5 to 10 As shown, the rotary telescopic mechanism 5 consists of a mounting frame 501, an adjusting shaft arm 502, a linkage shaft rod 503, a universal coupling 504, a threaded rod 505, a stirring rod 506, and a stirring paddle 507. A threaded guide sleeve 5011 is fixedly installed on the bottom of one side of the mounting frame 501. The adjusting shaft arm 502 is rotatably installed on the top of one side of the mounting frame 501. The linkage shaft rod 503 is movably connected to the adjusting shaft arm 502 through an assembly bolt. One end of the linkage shaft rod 503 is movably connected to the threaded rod 505 through the universal coupling 504. The threaded rod 505 is threaded through the threaded guide sleeve 5011. The stirring rod 506 is fixedly installed at the bottom end of the threaded rod 505, and the stirring paddle 507 is fixedly installed at the bottom end of the stirring rod 506. It should be noted that the mounting brackets 501 of the three rotary telescopic mechanisms 5 are fixedly installed on the tops of the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4, respectively, providing installation positions for the adjusting shaft arm 502 and the threaded guide sleeve 5011; the rotating drive of the adjusting shaft arm 502 drives the linkage shaft 503 to reciprocate around the universal coupling 504 as the axis; the linkage shaft 503 converts the oscillation into the telescopic motion of the threaded rod 505 through the universal coupling 504; during the telescopic process, the threaded rod 505 achieves forward and reverse rotation and up and down telescopic movement through the threaded guide sleeve 5011; the forward and reverse rotation and up and down telescopic movement of the threaded rod 505 drive the stirring paddle 507 to rotate forward and reverse while simultaneously telescopically moving up and down through the stirring rod 506, automatically adjusting the stirring position; Specifically, the drive mechanism 6 drives the adjusting shaft arm 502 to rotate, and the rotating adjusting shaft arm 502 drives the linkage shaft rod 503 to swing back and forth. The swinging linkage shaft rod 503 moves the threaded rod 505 through the universal coupling 504 to extend and retract inside the threaded guide sleeve 5011. While the threaded rod 505 is extending and retracting, the internal thread of the threaded guide sleeve 5011 rotates in both directions, so that the threaded rod 505 drives the stirring paddle 507 to rotate in both directions while extending and retracting. The reciprocating extension and rotation cause the alternating flow direction of polymer and water to form a continuous convection impact, which breaks down polymer molecular agglomeration, improves dispersion efficiency, reduces viscosity loss, and ensures that the agglomerated polymer is fully dispersed.

[0021] like Figure 10 As shown, the adjusting shaft arm 502 consists of a sliding rod 5021, a lead screw 5022, and a threaded sleeve seat 5023. One end of the sliding rod 5021 has a spline hole 5024. The lead screw 5022 is rotatably installed inside the sliding rod 5021, and one end of the lead screw 5022 extends to the outside of the sliding rod 5021. The threaded sleeve seat 5023 is threaded onto the outside of the lead screw 5022, and an assembly bolt is fixedly installed on the front of the threaded sleeve seat 5023. It should be noted that the sliding rod 5021 serves as a support component, internally accommodating and guiding the linear movement of the threaded sleeve seat 5023; the threaded rod 5022 drives the threaded sleeve seat 5023 to move linearly along its axial direction by rotation, and one end of the threaded rod 5022 extends out of the sliding rod 5021 for easy manual operation from the outside; the threaded sleeve seat 5023 is tightly connected to the threaded rod 5022 by threads, and an assembly shaft bolt is fixedly installed on its front side for rotatably connecting the linkage shaft 503; the linkage shaft 503 swings according to the position change of the threaded sleeve seat 5023, thereby affecting the extension and retraction stroke of the stirring rod 506 and the stirring paddle 507 at the bottom of the threaded rod 505; Specifically, by holding the extension end of the lead screw 5022 and rotating the lead screw 5022, the rotating lead screw 5022 drives the thread sleeve seat 5023 to move along the axial direction of the lead screw 5022. By adjusting the position of the thread sleeve seat 5023, the swing amplitude of the linkage shaft rod 503 is adjusted, thereby adjusting the stroke of the stirring rod 506 at the bottom of the threaded rod 505 to drive the stirring paddle 507 to extend and retract.

[0022] like Figure 9 As shown, two sets of eccentric brackets 2031 are fixedly sleeved on the outer side of the stirring rod 506, and the outer sides of the two sets of eccentric brackets 2031 are fixedly installed on the inner wall of the grinding barrel 203. It should be noted that the eccentric support 2031 consists of an eccentric wheel and three supports. The three supports are arranged in a ring array around the eccentric wheel. When the stirring rod 506 rotates, the eccentric wheel generates eccentric rotation. The eccentric wheel drives the grinding barrel 203 to rotate eccentrically inside the stirring barrel 201 through the three supports. When the eccentrically rotating grinding barrel 203 contacts the inner wall of the stirring barrel 201, the agglomerated polymer can be ground and crushed.

[0023] like Figures 7 to 8 As shown, the drive mechanism 6 consists of a drive motor 601 and a drive rod 602. The drive motor 601 is fixedly mounted on the mounting bracket 501 on the top of the third dispersion tank 4. One end of the drive rod 602 is fixedly connected to the output end of the drive motor 601. The drive rod 602 passes through the three mounting brackets 501 and is splinedly engaged with one end of the three adjusting shaft arms 502. It should be noted that the drive motor 601, as the core component of the entire drive mechanism 6, is responsible for providing rotational power; the drive rod 602 transmits the rotational motion of the drive motor 601 to the three adjusting shaft arms 502; specifically, when the drive motor 601 is energized, it drives the drive rod 602 at the output end to rotate, and the rotating drive rod 602 drives the three adjusting shaft arms 502 connected by splines to rotate synchronously, thereby realizing the synchronous driving of the three rotating telescopic mechanisms 5.

[0024] like Figure 8 As shown, the drive rod 602 consists of two shafts and three splined rods. The three splined rods are fixedly connected to each other by the two shafts, and each splined rod is engaged with the corresponding splined hole 5024 of the adjusting shaft arm 502. It should be noted that the three splined rods are respectively engaged with the splined holes 5024 at one end of the three sliding rods 5021; and the three splined rods are connected in series through two shafts, so that the drive motor 601 transmits power to one of the splined rods. Since the three splined rods are connected in series through two shafts, the other two splined rods can be driven to rotate through the two shafts. The rotating three splined rods can simultaneously drive the three adjusting shaft arms 502 connected to the splined holes 5024 to rotate synchronously, ensuring the synchronicity and stability of the drive rod 602 transmission.

[0025] like Figures 4 to 6 As shown, an adjustable overflow weir 202 is movably installed inside the first dispersion tank 2, and four baffles 204 are rotatably installed on the outside of the mixing tank 201 via shafts, and the four baffles 204 are distributed in a ring array around the outside of the mixing tank 201. It should be noted that adjustable overflow weirs 202 are movably installed inside the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4. These weirs are used to control the flow of polymer liquid from the first dispersion tank 2, the second dispersion tank 3, and the third dispersion tank 4 into the next dispersion tank at different heights, ensuring uniform liquid distribution and preventing overflow to a certain extent, thereby improving dispersion efficiency and safety. Four baffles 204 are arranged in a ring array around the outer side of the mixing tank 201 and are rotated by shafts. The main function of the baffles 204 is to change the flow direction of the polymer liquid during stirring, improve the motion state of polymer liquid particles, reduce local flow of polymer liquid in the mixing tank 201, and promote the full dispersion and dissolution of polymer and water.

[0026] like Figure 11 As shown, the adjustment mechanism 7 consists of a toothed ring 701, three bevel gears 702, a screw sleeve 703, a screw 704, a drive gear 705, and a servo motor 706. An inner toothed sleeve is fixedly installed on the inner wall of the toothed ring 701. The three bevel gears 702 are arranged in a ring array around the outer side of the toothed ring 701 and are meshed with the toothed ring 701. A screw sleeve 703 is fixedly installed on the bottom of each of the three bevel gears 702. The screw 704 is threaded through the inside of the screw sleeve 703, and the bottom end of the screw 704 is rotatably connected to the adjustable overflow weir 202 through a turntable. The inner side of the toothed ring 701 is meshed with the drive gear 705 through an inner sleeve. The top of the drive gear 705 is fixedly connected to the output end of the servo motor 706. It should be noted that the toothed ring 701, as a rotating component, meshes with the drive gear 705 through the inner toothed sleeve on its inner wall, receiving the power transmitted by the servo motor 706 through the drive gear 705, thereby realizing its own rotation; three bevel gears 702 are fixed in a ring array on the outside of the toothed ring 701, meshing with the toothed ring 701, and their bottoms are fixedly installed with the threaded sleeve 703, ensuring that the rotation of the bevel gears 702 can drive the threaded sleeve 703 to rotate synchronously; the screw 704 is threaded through the threaded sleeve 703, and its bottom end is rotatably connected to the adjustable overflow weir 202 through a turntable, so that the extension and retraction of the screw 704 can drive the vertical movement of the adjustable overflow weir 202; The servo motor 706 drives the drive gear 705 to rotate. The rotating drive gear 705 drives the toothed ring 701 to rotate through the inner tooth sleeve. The rotating toothed ring 701 drives the three threaded sleeves 703 to rotate synchronously through the three meshing bevel gears 702. The three synchronously rotating threaded sleeves 703 drive the three threaded screws 704 to move synchronously. The three synchronously moving screws 704 drive the adjustable overflow weir 202 to move vertically inside the first dispersion tank 2. Adjusting the position of the adjustable overflow weir 202 inside the first dispersion tank 2 allows for precise control of the overflow position.

[0027] like Figures 1 to 2As shown, a side box 101 is fixedly installed on one side of the protective box 1. A PLC control cabinet 102 is fixedly installed inside the side box 101. A delivery pump 103 is fixedly installed on the side of the side box 101 away from the PLC control cabinet 102. An interface seat 104 is installed at the input end of the delivery pump 103 through a pipe. The output end of the delivery pump 103 is connected to the top of the first dispersion tank 2 through a pipe. It should be noted that the protective enclosure 1 is used to protect the internal structure as a whole, while the side enclosure 101, as part of the protective enclosure 1, is fixedly installed on one side and mainly serves to support and fix the PLC control cabinet 102. The PLC control cabinet 102 is responsible for the control logic of the entire system. It controls the operating status of the entire equipment through its built-in program to ensure that the equipment can work automatically according to the preset process. The PLC control cabinet 102 is electrically connected to the conveying pump 103, the servo motor 706, and the drive motor 601 through wires. The conveying pump 103, as a key component, is mainly responsible for sucking the specified material from the input end to the output end. It is connected to the first dispersion tank 2 through a pipeline and can send the material into the first dispersion tank 2 for further processing. The interface socket 104 serves as a pipeline connection point to fix the input pipeline and ensure the stability and reliability of the material input. Specifically, after receiving the start command through the PLC control cabinet 102, the PLC control cabinet 102 controls the conveying pump 103 to start running. The conveying pump 103 draws material from the outside through the pipeline, enters the conveying pump 103 through the interface seat 104, and then the conveying pump 103 conveys the material to the top of the first dispersion tank 2 through the built-in pipeline, so as to achieve precise material conveying.
