Description

Technical Field

[0001] This application relates to the field of stirring devices, and in particular to a water-based sealant high-efficiency stirring reactor. Background Technology

[0002] In the production process of water-based sealants, the stirring reactor is the core equipment. Its stirring uniformity, viscosity compatibility, and ease of cleaning directly affect the sealant's adhesive quality, production efficiency, and the connection with subsequent processes.

[0003] Currently, most existing water-based sealant mixing reactors have fixed agitator blades, which cannot adjust the mixing posture according to the viscosity changes of the water-based sealant. This results in splashing when mixing low-viscosity materials, and high power consumption and uneven mixing when mixing high-viscosity materials. Furthermore, the agitator blades are prone to material adhesion, making cleaning difficult. Residual materials can contaminate the next batch of products, affecting product consistency. The cumbersome cleaning process also increases maintenance costs and downtime.

[0004] To address these issues, a water-based sealant-based high-efficiency stirred reactor is proposed. Summary of the Invention

[0005] The purpose of this application is to address the technical shortcomings of existing water-based sealant stirring reactors, such as severe material adhesion to the stirring blades and complex structures, making them difficult to clean. Compared to existing technologies, this application provides a water-based sealant high-efficiency stirring reactor, comprising: The vessel body is used to hold the water-based sealant; Deformable stirring blades are used for stirring water-based sealants, and the deformable stirring blades are generally in the form of a conical spiral structure. The adjustment mechanism is used to connect the upper and lower ends of the deformable stirring blade, and to change the spiral extension degree of the deformable stirring blade by adjusting the distance between the upper and lower ends of the deformable stirring blade. The deformable stirring blade adopts a mechanical adjustment and electromagnetic assisted deformation mechanism to adapt to the stirring needs of water-based sealants of different viscosities.

[0006] Furthermore, the deformable stirring blade includes a plastic coating layer, and a conical spiral inner skeleton is fixed inside the plastic coating layer. Several equally spaced positioning plates are symmetrically arranged on both radial sides of the conical spiral inner skeleton, and a conical spiral bladder is arranged between adjacent positioning plates. The conical spiral bladder is filled with magnetorheological fluid. The conical spiral inner skeleton is equipped with an electromagnetic plate that cooperates with the conical spiral bladder. The viscosity of the magnetorheological fluid is adjusted by the change in the magnetic field strength generated by the electromagnetic plate, which helps to control the deformation rigidity of the deformable stirring blade.

[0007] Furthermore, the adjustment mechanism includes an outer shaft sleeve rod, which is rotatably connected to the top inner side of the vessel body. An inner shaft rod is slidably connected to the outer shaft sleeve rod in the vertical direction through a spline groove. An upper fixed seat is fixed to the bottom of the outer shaft sleeve rod, and a lower fixed seat is fixed to the bottom of the inner shaft rod. The top of the plastic coating layer is fixed with an upper rotating seat, and an upper connecting rod is rotatably connected inside the upper rotating seat. The bottom of the plastic coating layer is fixed with a lower rotating seat, and a lower connecting rod is rotatably connected inside the lower rotating seat. A universal ball joint is fixed at one end of the upper and lower connecting rods near the outer bushing rod. A ball joint seat that mates with the universal ball joint is fixed on both the upper and lower fixed seats.

[0008] Furthermore, auxiliary blades are also fixed on the lower connecting rod to enhance the uniformity of stirring of materials at the bottom of the vessel.

[0009] Furthermore, when the deformable stirring blade is stretched to its maximum stroke, the side of the plastic coating layer near the outer shaft sleeve tends to tilt upwards; when the deformable stirring blade is compressed to its maximum stroke, the maximum outer diameter of the plastic coating layer is equal to the inner diameter of the vessel body, which is used for wall scraping and cleaning.

[0010] Furthermore, the outer top of the plastic coating layer is provided with a snap-fit ​​bevel, and the inner top of the plastic coating layer is provided with a snap-fit ​​protrusion that matches the snap-fit ​​bevel. When the deformable stirring blade is compressed to its maximum stroke, the snap-fit ​​bevel and the snap-fit ​​protrusion engage with each other to enhance the structural integrity of the deformable stirring blade under compressed state, thereby enabling self-cleaning by utilizing high-speed centrifugal force.

[0011] Furthermore, a drive motor is fixed to the top of the vessel body, and the output end of the drive motor is connected to the top of the outer shaft sleeve through a spline groove. A hydraulic telescopic rod one and a hydraulic telescopic rod two are also fixed to the top of the vessel body. The output end of the hydraulic telescopic rod one is connected to the outer shaft sleeve through a rotary joint and is used to drive the lifting and lowering of the outer shaft sleeve while avoiding synchronous rotation with the outer shaft sleeve. The hydraulic telescopic rod two is used to drive the lifting and lowering of the inner shaft.

[0012] Furthermore, after the conical spiral of the deformable stirring blade rotates one revolution, the radial distance between it and the axis of the outer shaft sleeve is equal to the cross-sectional width of the plastic coating layer in the horizontal direction.

[0013] Furthermore, the outer wall of the plastic coating is coated with a nano anti-stick coating to reduce the adhesion of water-based sealant to the surface of the plastic coating.

[0014] Compared to existing technologies, the advantages of this application are: This invention achieves mechanical adjustment of the spiral extension degree of the stirring blade through the coordinated design of the deformable stirring blade and the adjustment mechanism. Combined with the electromagnetic assisted deformation mechanism of the electromagnetic plate and magnetorheological fluid, the rigidity of the stirring blade can be precisely controlled to adapt to the stirring requirements of water-based sealants of different viscosities, thereby improving the versatility and stirring adaptability of the equipment. It also eliminates the need to replace the stirring blade and reduces the complexity of operation.

[0015] When cleaning is required, the deformable stirring blades are compressed to their maximum stroke, and the maximum outer diameter of the plastic coating layer is equal to the inner diameter of the vessel body. This achieves an integrated design of the stirring blades and the wall scraping structure, eliminating the need for an additional independent wall scraping device. At the same time, the interlocking bevel and interlocking protrusion of the plastic coating layer enhance the overall structural integrity when the stirring blades are compressed, providing a structural foundation for high-speed centrifugal self-cleaning. Self-cleaning is achieved through high-speed centrifugal force, eliminating the need for manual disassembly and cleaning, significantly reducing maintenance costs and downtime, and improving production continuity.

[0018] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0019] Example: This invention provides a high-efficiency stirred reaction vessel for water-based sealants. Please refer to [link / reference]. Figure 1 - Figure 9 , Among them, the vessel body 1 serves as the supporting foundation for the entire reactor, used to contain water-based sealant materials and provide installation support for other components. Its inner diameter is adapted to the maximum outer diameter of the deformable stirring blade 5 under compressed state, ensuring the wall scraping function is realized.

[0020] The core stirring component is the deformable stirring blade 5, which has an overall conical spiral structure. It is used to achieve the stirring, mixing and reaction of water-based sealant. It adopts mechanical adjustment and electromagnetic assisted deformation mechanism to adapt to the needs of materials with different viscosities.

[0021] The deformable stirring blade 5 includes a plastic coating layer 51, within which a conical spiral inner skeleton 54 is fixed, providing basic support for the stirring blade. A plurality of equally spaced positioning plates 541 are symmetrically arranged on both radial sides of the conical spiral inner skeleton 54 for positioning and fixing the conical spiral capsule 55. Conical spiral capsules 55 are positioned between adjacent positioning plates 541, and are filled with magnetorheological fluid. An electromagnetic plate 56, which cooperates with the conical spiral capsule 55, is located within the conical spiral inner skeleton 54. The magnetic field strength generated by the electromagnetic plate 56... The viscosity of the magnetorheological fluid is adjusted to help control the deformation rigidity of the deformable stirring blade 5. Specifically, when the deformable stirring blade 5 is stretched to a certain stroke, the included angle between adjacent positioning plates 541 changes. At this time, the magnetic field strength is adjusted by the electromagnetic plate 56 to increase the viscosity of the magnetorheological fluid in the conical spiral capsule 55 and reduce its fluidity, thereby controlling the included angle between adjacent positioning plates 541. At the same time, the magnetorheological fluid in the overall conical spiral capsule 55 also provides reinforcement to the conical spiral inner skeleton 54 under the action of the magnetic field, maintaining rigidity.

[0022] The outer top of the plastic coating layer 51 is provided with a snap-fit ​​bevel 511, and the inner top is provided with a snap-fit ​​protrusion 512 for structural positioning under compression; the outer wall is coated with a nano anti-stick coating to reduce material adhesion.

[0023] The adjustment mechanism 4 is used to drive the deformable stirring blade 5 to deform, and connects the upper and lower ends of the deformable stirring blade 5. The degree of spiral extension of the stirring blade is changed by adjusting the distance between the upper and lower ends. The adjustment mechanism 4 specifically includes an outer shaft sleeve 41 and an inner shaft 42. The outer shaft sleeve 41 is rotatably connected to the top of the inner side of the vessel body 1, and the inner shaft 42 is slidably connected to the outer shaft sleeve 41 in the vertical direction through a spline groove to achieve synchronous rotation and relative lifting. The bottom of the outer shaft sleeve 41 is fixed with an upper fixed seat 411, and the bottom of the inner shaft 42 is fixed with a lower fixed seat 421. The top of the deformable stirring blade 5 is fixed with an upper rotating seat 52, and the upper connecting rod 412 is rotatably connected inside the upper rotating seat 52. The bottom is fixed with a lower rotating seat 53, and the lower connecting rod 422 is rotatably connected inside the lower rotating seat 53. The ends of the upper connecting rod 412 and the lower connecting rod 422 near the shaft are both fixed with universal ball joints 402. Matching ball joint seats 401 are fixed on the upper fixed seat 411 and the lower fixed seat 421. Through the cooperation of the universal ball joints 402 and the ball joint seats 401, the flexible connection between the connecting rod and the shaft is achieved, ensuring smooth deformation of the stirring blade. The lower connecting rod 422 is fixed with auxiliary blades 423, which are used to stir the material at the bottom of the vessel body 1 and eliminate the dead zone of stirring.

[0024] A drive motor 2 is fixed at the top of the vessel body 1. Its output end is connected to the top of the outer shaft sleeve 41 via a spline groove, providing power for the rotation of the outer shaft sleeve 41 and the inner shaft 42. A hydraulic telescopic rod 1 3 and a hydraulic telescopic rod 2 6 are also fixed at the top. The output end of the hydraulic telescopic rod 1 3 is connected to the outer shaft sleeve 41 via a rotary joint, driving the outer shaft sleeve 41 to rise and fall, while preventing it from rotating synchronously with the outer shaft sleeve 41. The hydraulic telescopic rod 2 6 drives the inner shaft 42 to rise and fall. The relative rise and fall of the outer shaft sleeve 41 and the inner shaft 42 adjusts the distance between the upper and lower ends of the deformable stirring blade 5.

[0025] When the deformable stirring blade 5 is compressed to its maximum stroke, the maximum outer diameter of the plastic coating layer 51 is equal to the inner diameter of the vessel body 1, thus achieving wall scraping and cleaning. At this time, the snap-fit ​​bevel 511 and the snap-fit ​​protrusion 512 are aligned to enhance the overall structure of the stirring blade. When rotating at high speed, centrifugal force is used to throw off the material adhering to the surface, thus achieving self-cleaning.

[0026] After the conical spiral of the deformable stirring blade 5 rotates one revolution, the radial distance between it and the axis of the outer shaft sleeve 41 changes to be equal to the cross-sectional width of the plastic coating layer 51 in the horizontal direction, ensuring the continuity of the spiral structure and the stirring stability during the deformation of the stirring blade.

[0027] In the initial state, the deformable stirring blade 5 is in a naturally extended state, and the plastic coating layer 51 leaves a gap with the inner wall of the vessel body 1; the auxiliary blade 423 is located at the bottom of the vessel body 1; the electromagnetic plate 56 is in a de-energized state, the magnetorheological fluid is in a low viscosity state, and the stirring blade has the lowest rigidity.

[0028] According to the viscosity of the water-based sealant to be stirred, the state of the stirring blade is adjusted by adjusting mechanism 4 and electromagnetic plate 56. Hydraulic telescopic rod 1 3 and hydraulic telescopic rod 2 6 are activated to drive the outer shaft sleeve rod 41 and inner shaft rod 42 to rise and fall relative to each other, changing the distance between the upper and lower ends of the deformable stirring blade 5. When the material viscosity is high, the distance between the upper and lower ends is increased, so that the spiral extension degree of the stirring blade is increased, the stirring radius is increased, and the stirring torque is increased. When the material viscosity is low, reduce the distance between the upper and lower ends to reduce the spiral extension of the stirring blades and avoid material splashing.

[0029] During this process, based on the flow resistance of the material during stirring, the electromagnetic plate 56 is energized. By adjusting the current intensity, the magnetic field strength is changed, thereby adjusting the viscosity of the magnetorheological fluid: when the resistance is high, the magnetic field strength is increased, the viscosity of the magnetorheological fluid increases, the rigidity of the stirring blades is enhanced, and excessive deformation of the stirring blades is avoided; when the resistance is low, the magnetic field strength is decreased, the viscosity of the magnetorheological fluid decreases, the flexibility of the stirring blades is enhanced, and the uniformity of stirring is improved. The cooperation between the universal ball joint 402 and the ball joint seat 401 ensures that the upper connecting rod 412 and the lower connecting rod 422 can rotate flexibly with the deformation of the stirring blades, avoiding mechanical interference.

[0030] During the high-efficiency stirring stage, the drive motor 2 is started, and the power is transmitted to the outer shaft sleeve 41 and the inner shaft 42 through the spline groove, which drives the deformable stirring blade 5 to rotate synchronously and stir the water-based sealant in the vessel body 1. During the stirring process, the auxiliary blade 423 rotates synchronously with the lower connecting rod 422 to stir the material at the bottom of the vessel body 1, eliminate the stirring dead corners, and ensure that the material is fully mixed and reacted. The nano anti-stick coating on the outer wall of the plastic coating layer 51 reduces the adhesion of material to the surface of the stirring blade.

[0031] After mixing, when cleaning the vessel wall is required, the outer shaft sleeve 41 and inner shaft 42 are moved relative to each other by hydraulic telescopic rod 3 and hydraulic telescopic rod 6, so that the deformable stirring blade 5 is compressed to its maximum stroke. At this time, the maximum outer diameter of the plastic coating layer 51 is equal to the inner diameter of the vessel body 1. The drive motor 2 is started to drive the stirring blade to rotate at low speed. The outer side of the plastic coating layer 51 is tightly attached to the inner wall of the vessel body 1 to achieve wall scraping and cleaning, scraping off the material adhering to the vessel wall. At the same time, the snap-fit ​​bevel 511 and snap-fit ​​protrusion 512 of the plastic coating layer 51 are aligned to enhance the structural integrity of the stirring blade. The speed of the drive motor 2 is increased, and the centrifugal force generated by the high-speed rotation is used to throw off the material adhering to the surface of the stirring blade and the snap-fit ​​structure, achieving self-cleaning. After cleaning, the stirring blade is adjusted to return to its natural extended state, waiting for the next batch of material to be mixed.

[0032] This invention achieves mechanical adjustment of the spiral extension degree of the stirring blade through the coordinated design of the deformable stirring blade 5 and the adjustment mechanism 4. Combined with the electromagnetic plate 56 and the electromagnetic assisted deformation mechanism of magnetorheological fluid, the rigidity of the stirring blade can be precisely controlled to adapt to the stirring requirements of water-based sealants of different viscosities, thereby improving the versatility and stirring adaptability of the equipment. There is no need to replace the stirring blade, which reduces the complexity of operation.

[0033] When cleaning is required, the deformable stirring blade 5 is compressed to its maximum stroke, and the maximum outer diameter of the plastic coating layer 51 is equal to the inner diameter of the vessel body 1. This achieves an integrated design of the stirring blade and the wall scraping structure, eliminating the need for an additional independent wall scraping device. At the same time, the engagement of the snap-fit ​​bevel 511 and snap-fit ​​protrusion 512 of the plastic coating layer 51 enhances the overall structural integrity under the compressed state of the stirring blade, providing a structural foundation for high-speed centrifugal self-cleaning. Self-cleaning is achieved through high-speed centrifugal force, eliminating the need for manual disassembly and cleaning, significantly reducing maintenance costs and downtime, and improving production continuity.

[0034] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
