Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, specifically to a high-mixing homogenizer. Background Technology

[0002] As is well known, a high-speed homogenizing reactor is a reactor with a high-speed homogenizer installed at the top to achieve stirring and mixing of materials inside the reactor. A high-speed homogenizer is an industrial device that achieves uniform mixing of materials through mechanical action. The high-speed homogenizer generates high-frequency, strong circumferential tangential velocity, angular velocity and other comprehensive kinetic energy efficiency through the high-speed and stable rotation of the rotor. Under the action of the stator, the stator and rotor form a strong, reciprocating hydraulic shearing, friction, centrifugal extrusion and liquid flow collision combined effect in the narrow gap. The material circulates in the container and repeats the above working process, finally obtaining a highly efficient mixed and homogenized product.

[0003] High-speed homogenizers are widely used in industrial production. Due to their special applications, the mixing effect and equipment reliability of high-speed homogenizers are particularly important. The mixing and homogenization of materials is a key link to ensure product quality and reaction efficiency. Therefore, a good high-speed homogenizer is extremely important for chemical production.

[0004] For example, patent CN208389852U, published on January 18, 2019, and titled "Single-Head Homogenizer," proposes a single-head homogenizer including a reaction chamber. A sealing cover is fixed to the upper surface of the reaction chamber, and a feeding port is provided on the sealing cover. A rotatable main shaft is connected to the lower end of the sealing cover and is located inside the reaction chamber. The main shaft has a first homogenizing section, a second homogenizing section, and a third homogenizing section arranged sequentially from top to bottom. This patent designs a simple homogenizer that, through a layered guiding structure, allows for better mixing and blending of the ink, achieving a homogenizing effect.

[0005] The shortcoming of the existing technology is that the existing homogenizers all achieve the mixing of materials by the cooperation between the rotor and the stator, so that the rotor and the stator form a strong, reciprocating hydraulic shearing, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects in a narrow gap. However, during the rotation of the rotor, eddies and dead corners are generated between the stator and the rotor, thereby reducing the homogenization effect of the materials. Utility Model Content

[0006] The purpose of this invention is to provide a high-mixing homogenizing reactor to solve the above-mentioned problems in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-mixing homogenizing reactor, including a reactor, a motor body, and a flange. The top of the reactor is fitted with a flange, and the top of the flange is fitted with a motor body via a frame. The output end of the motor body is connected to a rotor, and the bottom of the flange is fitted with a stator located outside the rotor. The rotor and stator are coaxially arranged and have a gap between them. Multiple guide grooves for material inlet and outlet are evenly arranged along the circumferential direction on the inner wall of the stator.

[0008] As described above, the outer wall of the rotor is provided with blades for stirring the material, and the blades have a spiral blade structure.

[0009] As described above, the rotor and the output end of the motor body are connected by a stirring shaft.

[0010] As described above, the flange seal is installed on the reactor, the motor body is located outside the reactor, the connection position between the output end of the motor body and the stirring shaft is located at the center of the flange, and the rotor and stator are located inside the reactor to achieve the mixing operation of materials.

[0011] As mentioned above, the connection between the output end of the motor body and the stirring shaft on the flange is made by a double-end mechanical seal, which adopts the Plan53A mechanical seal system.

[0012] The Plan53A mechanical seal system described above is connected to a lubrication tank via a pipe.

[0013] As described above, the bottom of the flange and the stator are connected by a plurality of evenly arranged fixed legs.

[0014] The stator described above includes a fixed ring, an adjusting ring, and a baffle. The fixed ring is connected to the bottom of the flange by a plurality of evenly arranged fixed legs. Both the fixed ring and the adjusting ring have a plurality of evenly arranged grooves, which are arranged in a one-to-one correspondence. The corresponding grooves on the fixed ring and the adjusting ring are all connected by a baffle in a spherical manner. The two ends of the baffle are respectively spherically connected to the corresponding grooves on the fixed ring and the adjusting ring.

[0015] As described above, multiple positioning plates are evenly arranged on the outer walls of the fixed ring and the adjusting ring along their circumferential direction. The positioning plates on the fixed ring and the adjusting ring are arranged one-to-one. Each positioning plate is provided with multiple adjusting slots, and the adjusting slots on each corresponding positioning plate are arranged correspondingly.

[0016] The aforementioned adjusting slots on each positioning plate are connected by double-ended bolts.

[0017] The beneficial effects of this invention are as follows: When the rotor and stator are mixing materials, the guide channel is used to transport and discharge the materials. The guide channel on the stator changes the flow path of the fluid, thereby reducing the eddies and dead zones generated by the materials on the stator, making the materials more evenly distributed in the shearing area between the stator and rotor, thus improving the utilization rate of shearing force. In addition, the guide channel can guide the materials to form a more stable high-speed shear flow, refine the dispersed phase into smaller particles, reduce interfacial tension, reduce droplet coalescence, and improve the stability of the mixing system. By optimizing the fluid flow, the guide channel can reduce unnecessary energy consumption, while also reducing mechanical wear on the stator and rotor, and extending the service life of the equipment.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 9 As shown, the high-mixing homogenizing reactor provided in this embodiment of the present invention includes a reactor 20, a motor body 1, and a flange 2. The flange 2 is installed on the top of the reactor 20, and the motor body 1 is installed on the top of the flange 2 via a frame 6. The output end of the motor body 1 is connected to a rotor 3. The bottom of the flange 2 is located outside the rotor 3 and a stator 4 is installed. The rotor 3 and the stator 4 are coaxially arranged and have a gap between them. Multiple guide grooves 5 for material inlet and outlet are evenly arranged on the inner wall of the stator 4 along its circumferential direction.

[0032] Specifically, a high-speed homogenizing reactor is an industrial device that uses a high-speed homogenizer installed on top of a reaction vessel to stir and mix the materials inside the reaction vessel. The high-speed homogenizer is used to achieve uniform mixing of materials through mechanical action. High-speed homogenizing reactors are commonly used for mixing solutions. The reactor includes a reaction vessel 20, a motor body 1, and a flange 2. The flange 2 is installed on the reaction vessel 20 in a sealed manner. The reaction vessel 20 is a container for loading materials. The motor body 1 is mounted on the top of the flange 2 via a frame 6. The motor body 1 is the motor that provides rotational power to the rotor 3. The speed of the motor body 1 can be adjusted using electronic control technology. This is a feature of the art. As is common knowledge and will not be elaborated upon, the motor body 1 is located on top of the flange 2 and outside the reactor 20. The output end of the motor body 1 is connected to a stirring shaft 7, and the end of the stirring shaft 7 is connected to a rotor 3. The outer wall of the rotor 3 is equipped with blades 8 for stirring materials; these blades 8 have a helical blade structure. The connection between the output end of the motor body 1 and the stirring shaft 7 is located at the center of the flange 2. The rotor 3 and stator 4 are located inside the reactor 20 to achieve material mixing. The connection between the output end of the motor body 1 and the stirring shaft 7 on the flange 2 is achieved through a double-end mechanical seal 9. The double-end mechanical seal 9 uses a P... The Plan 53A mechanical seal system, connected to a lubrication tank 10 via a pipe, is a double-end mechanical seal system. The Plan 53A mechanical seal system achieves its function through the circulation of a separating fluid, primarily providing lubrication, cooling, and pressure balance to the sealing surfaces. A key feature of the Plan 53A mechanical seal system is that it uses a pressurizer, reservoir, or lubrication tank 10 to pressurize the sealing fluid, causing it to circulate within the sealing cavity. This removes heat generated by friction and lubricates the sealing surfaces. The Plan 53A mechanical seal system requires maintaining a pressure within the sealing cavity higher than the medium pressure (typically 0.5-1 liters higher).(5 bar) to prevent media leakage. The working principle and effects of the Plan 53A mechanical seal system are common knowledge in the field and will not be elaborated here. The bottom of the flange 2 and the stator 4 are connected by a plurality of evenly arranged fixed legs 11. The stator 4 is located outside the rotor 3 and is coaxially arranged. There is a certain gap between the stator 4 and the rotor 3, but the gap between the stator 4 and the rotor 3 is very small. The spiral blades 8 on the outer wall of the rotor 3 are adapted to each other with the stator 4. A plurality of guide grooves 5 for material inlet and outlet are evenly arranged along the circumferential direction on the inner wall of the stator 4. Material enters and exits in the guide grooves 5. When it is necessary to mix the material, the motor body 1 is started to drive the stirring shaft 7 to rotate. The stirring shaft 7 drives the rotor 3 and the blades 8 to rotate. The rotor 3 rotates inside the stator 4, so that a strong and reciprocating force is formed in the narrow gap between the rotor 3 and the stator 4. The combined effects of hydraulic shearing, friction, centrifugal extrusion, and fluid collision achieve material mixing, refining the materials and enabling more uniform mixing, thus making the mixture system more stable. The guide channel 5 facilitates material conveying and discharge. The guide channel 5 on the stator 4 alters the fluid flow path, reducing eddies and dead zones on the stator 4, resulting in a more uniform distribution of material in the shearing region between the stator 4 and rotor 3, thereby improving the utilization rate of shear force. Furthermore, the guide channel 5 guides the material to form a more stable high-speed shear flow, refining the dispersed phase into smaller particles, reducing interfacial tension, minimizing droplet coalescence, and improving the stability of the mixture system. By optimizing fluid flow, the guide channel 5 reduces unnecessary energy consumption and alleviates mechanical wear on the stator 4 and rotor 3, extending the equipment's service life.

[0033] The shortcoming of the existing technology is that the existing homogenizers all achieve the mixing of materials by the cooperation between the rotor 3 and the stator 4, so that the rotor 3 and the stator 4 form a strong, reciprocating hydraulic shearing, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects in the narrow gap. However, during the rotation of the rotor 3, eddies and dead corners will be generated between the stator 4, thereby reducing the homogenization effect of the materials.

[0034] The beneficial effects of this embodiment are as follows: When the rotor 3 and stator 4 are mixing materials, the materials are conveyed and discharged through the guide channel 5. The guide channel 5 on the stator 4 changes the flow path of the fluid, thereby reducing the eddies and dead zones generated by the materials on the stator 4, making the materials more evenly distributed in the shearing area between the stator 4 and the rotor 3, thereby improving the utilization rate of shearing force. In addition, the guide channel 5 can guide the materials to form a more stable high-speed shear flow, refine the dispersed phase into smaller particles, reduce interfacial tension, reduce droplet coalescence, and improve the stability of the mixing system. By optimizing the fluid flow, the guide channel 5 can reduce unnecessary energy consumption, while also reducing the mechanical wear of the stator 4 and the rotor 3, and extending the service life of the equipment.

[0035] In another embodiment of this utility model, the stator 4 includes a fixed ring 12, an adjusting ring 13, and a baffle 14. The fixed ring 12 is connected to the bottom of the flange 2 by a plurality of evenly arranged fixed supports 11. Both the fixed ring 12 and the adjusting ring 13 have a plurality of evenly arranged grooves 15, which correspond one-to-one. The corresponding grooves 15 on the fixed ring 12 and the adjusting ring 13 are all spherically connected by the baffle 14. The two ends of the baffle 14 are respectively connected to… The fixed ring 12 and the adjusting ring 13 are spherically connected to their corresponding grooves 15. Multiple positioning plates 16 are evenly arranged along the circumferential direction on the outer walls of the fixed ring 12 and the adjusting ring 13. The positioning plates 16 on the fixed ring 12 and the adjusting ring 13 are arranged in a one-to-one correspondence. Each positioning plate 16 is provided with multiple adjusting slots 17, and the adjusting slots 17 on each corresponding positioning plate 16 are arranged correspondingly. The corresponding adjusting slots 17 on each positioning plate 16 are connected by double-ended bolts 18 and nuts 19.

[0036] Specifically, because the guide groove 5 on the stator 4 is always planar (e.g. Figure 8 As shown), however, in actual use, the shape of the guide groove 5 on the stator 4 needs to be changed, that is, the side of the guide groove 5 is modified to a parallelogram structure (as shown). Figure 9As shown, when it is necessary to replace the shape of the guide groove 5 on the stator 4, the worker uses tools to remove the nuts 19 from the screws on each double-ended bolt 18, and then removes the double-ended bolt 18 from one end of the adjusting ring 13, so that the double-ended bolt 18 is removed from the adjusting groove 17 on the adjusting ring 13. Then, the adjusting ring 13 is rotated to drive the positioning plate 16 to rotate. The positioning plate 16 has multiple adjusting grooves 17 evenly arranged on it. The adjusting ring 13 drives the adjusting grooves 17 on the positioning plate 16 to be misaligned with each other, while one end of the double-ended bolt 18 in the adjusting groove 17 on the positioning plate 16 on the positioning ring does not rotate. Then, the double-ended bolt 18 is inserted into the adjusting groove 17 on the adjusting ring 13, so that the adjusting groove 17 on the positioning plate 16 on the adjusting ring 13 and the positioning plate 16 on the positioning ring 13 are aligned. The adjusting grooves 17 on stator 6 are misaligned, and then the positioning ring and adjusting ring 13 are locked and positioned by double-headed bolts 18. Simultaneously, since the corresponding grooves 15 on the fixed ring 12 and adjusting ring 13 are spherically connected by baffles 14, the two ends of the baffles 14 are spherically connected to the corresponding grooves 15 on the fixed ring 12 and adjusting ring 13 respectively (the spherical connection is a common knowledge in the field, which allows the two parts to move freely in multiple directions through a spherical connector, and will not be elaborated). The adjusting ring 13 drives the baffles 14 to rotate at a certain angle, so that the two adjacent baffles 14 are still parallel, but the included angle between the baffles 14 and the positioning ring and the adjusting ring 13 changes, thereby changing the shape of the guide groove 5 on stator 4.

[0037] When the cross-section of the guide groove 5 on the stator 4 is a rectangular structure (e.g.) Figure 8 When the rotor 3 rotates inside the stator 4, a strong, reciprocating hydraulic shearing, friction, centrifugal extrusion, and fluid collision combined effect is formed in the narrow gap between the rotor 3 and the stator 4, achieving a mixing process of materials. This refines the materials, allowing them to mix more evenly and thus making the mixture system more stable. Furthermore, the guide channel 5 transports and discharges the materials. The guide channel 5 on the stator 4 changes the fluid flow path, reducing eddies and dead zones on the stator 4, and making the material more evenly distributed in the shearing area between the stator 4 and the rotor 3, thereby improving the utilization rate of shearing force. When the cross-section of the guide channel 5 on the stator 4 is a parallelogram structure (e.g., ...), Figure 9 As shown in the diagram, in addition to general material convection, the material is subjected to both radial thrust and axial force during upward injection. Therefore, it exhibits significant effects in emulsifying, dispersing, homogenizing, mixing, and pulverizing materials that are prone to agglomeration, flocculation, suspension, or adhesion. Consequently, it can rapidly pulverize particles in materials into submicron fineness within a very short time.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
