Abstract
Description
Technical Field
[0001] This invention relates to the field of mixing equipment technology, and more specifically, to a microwave high-voltage synergistic mica paper binder mixing equipment. Background Technology
[0002] Mica paper adhesive is a special adhesive system specifically designed for bonding and encapsulating mica flakes. It is typically composed of high-temperature resistant resins (such as silicone and epoxy), inorganic fillers, curing agents, and solvents. Its core characteristics include excellent electrical insulation, high heat resistance (up to H-class or higher), good bonding strength, and stable chemical inertness. It is widely used in high-temperature insulation applications such as motors and heating elements.
[0003] When producing this binder, mixing equipment is required to efficiently and uniformly disperse and blend the components. In practice, it has been found that moderate heating can effectively reduce the viscosity of the material and promote molecular diffusion, thereby significantly improving the mixing efficiency. However, heating also exacerbates the adhesion and skinning of the material on the inner wall of the mixing tank. Although traditional scrapers can remove most of the material adhering to the wall, the viscous material that is scraped off often re-accumulates on the scraper body and its root, forming secondary retention. This not only reduces the scraping effect but may also cause the raw material to pre-cur due to local overheating, affecting the consistency and performance of the final product. Summary of the Invention
[0004] This invention provides a microwave-high pressure co-operated mica paper adhesive mixing device, which solves the problems mentioned in the background art by using a microwave heater and a reciprocating elastic scraper, namely: the material easily adheres to the inner wall of the tank and the viscous material accumulates on the scraper body.
[0005] To achieve the above objectives, a microwave-high voltage synergistic mica paper adhesive mixing device includes a support frame, a horizontally arranged mixing tank mounted on the support frame, a main motor mounted on the support frame, an output end of the main motor connected to a stirring shaft extending into the mixing tank, a booster pump mounted on the support frame, the output end of the booster pump extending into the mixing tank, a microwave heater mounted on the top of the mixing tank, the microwave output end of the microwave heater facing the interior of the mixing tank; a stirring blade is connected to the outer wall of the stirring shaft, and an elastic scraper is connected to the stirring blade. The end of the elastic scraper is inclined and abuts against the inner wall of the mixing tank, forming a wedge-shaped extrusion zone between the scraper and the inner wall of the mixing tank. The stirring shaft is provided with a top pressure drive unit, which is used to drive the elastic scraper to intermittently undergo elastic top pressure deformation towards the inner wall of the mixing tank. When the top pressure drive unit drives the scraper to press down, the volume of the wedge-shaped extrusion zone gradually decreases, generating extrusion and shearing action on the retained material. When the top pressure drive unit drives the scraper to reset, the volume of the wedge-shaped extrusion zone gradually increases, generating local negative pressure to promote the backfilling of new material into the wedge-shaped extrusion zone.
[0006] In the above technical solution, the top-pressure drive unit includes a strip plate that is slidably installed along the radial direction of the stirring paddle. The scraper is fixedly installed on the outer end of the strip plate. The stirring shaft has an axially extending cavity inside. The inner end of the strip plate extends into the cavity. Multiple circumferentially distributed top blocks are arranged in the cavity. The inner end of the strip plate is connected to a protrusion corresponding to the top block. When the stirring shaft rotates, the multiple top blocks periodically press against the protrusion. The outer wall of the mixing tank is connected to an inner rod extending into the cavity. The multiple top blocks are all connected to the outer wall of the inner rod, which is used to make the elastic scraper intermittently press against the inner wall of the mixing tank.
[0007] Based on the above, the main body of the stirring paddle is a flat plate structure. Multiple first guide grooves extending to the back are formed on the force-bearing surface facing the material. When the stirring shaft drives the stirring paddle to rotate, the material entering the first guide groove flows towards the axis of the mixing tank under the guidance of the groove wall. Multiple second guide grooves opposite to the direction of the first guide grooves are formed on the stirring paddle. When the stirring shaft drives the stirring paddle to rotate, the material entering the second guide groove flows towards the inner wall of the mixing tank under the guidance of the groove wall, so as to enable the stirring paddle to have better mixing ability.
[0008] Secondly, the strip plate has multiple equally spaced slots along its length; when the strip plate slides, the slots can be aligned with the output end of the first guide channel, the output end of the second guide channel, or both output ends simultaneously, so as to generate continuous changes in the direction and intensity of the material flow field.
[0009] Furthermore, multiple guide blocks are fixedly connected to the force-bearing surface of the stirring paddle. Each guide block has two symmetrically arranged guide ramps, which together form a wedge-shaped flow guiding structure. When the guide block rotates with the stirring paddle, the guide ramps can divert the incoming material to both sides of the stirring paddle, thereby guiding the raw material into the area between adjacent stirring paddles in the axial direction.
[0010] Therefore, by integrating microwave bulk heating and pressurization environment, it prevents wall adhesion and bubble generation from the source. Its elastic scraper has a periodic self-cleaning function, which can powerfully remove itself and the deposits on the tank wall, reducing secondary accumulation. Combined with dynamic flow guidance design, it forms a high-intensity changing flow field to achieve efficient material dispersion.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] 1. In this microwave-high pressure co-processed mica paper binder mixing equipment, the raw materials in the mixing tank are heated by a microwave heater, resulting in better heating uniformity. The inner wall of the mixing tank is less likely to experience localized overheating, which could lead to adhesion, thus ensuring the final quality of the mica binder. The booster pump increases the pressure inside the mixing tank, and the pressurized environment makes it less likely for the raw materials to generate air bubbles, improving the penetration efficiency between the raw materials. Combined with the microwave heating environment, this results in better mixing of the mica binder.
[0013] 2. In this microwave high-pressure synergistic mica paper binder mixing equipment, the elastic scraper is driven to intermittently press against the tank wall. During the pressing stage, the volume of the wedge-shaped extrusion zone decreases, generating strong shearing and extrusion effects on the material in the zone. On the one hand, it forcibly squeezes out the raw materials that may adhere to the outer wall of the scraper, preventing them from accumulating for a long time and affecting the scraping effect. On the other hand, it also instantly increases the contact pressure between the scraper and the tank wall, enhancing the scraping force.
[0014] 3. In this microwave high-pressure synergistic mica paper binder mixing device, the first guide channel, the second guide channel and the guide block work together to construct axial and radial composite convection, while the dynamic grooving of the strip plate periodically changes the flow channel, forming a constantly changing three-dimensional strong shear flow field, which fundamentally improves the dispersion efficiency and mixing uniformity.

[0025] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0026] In practice, it has been found that moderate heating can effectively reduce the viscosity of materials and promote molecular diffusion, thereby significantly improving mixing efficiency. However, heating also exacerbates the adhesion and crusting of materials on the inner wall of the mixing tank. Although traditional scrapers can remove most of the material adhering to the wall, the viscous material that is scraped off often re-accumulates on the scraper body and its root, forming secondary retention. This not only reduces the scraping effect but may also cause the raw materials to pre-cure due to local overheating, affecting the consistency and performance of the final product.
[0027] Therefore, in view of the above-mentioned problems, the present invention discloses a microwave high-voltage synergistic mica paper binder mixing device, with reference to... Figures 1-3 As shown, the system includes a support 1, on which a horizontally arranged mixing tank 2 is mounted. The top and bottom of the mixing tank 2 are respectively provided with a feed inlet 22 and a discharge outlet 23. The mixing tank 2 is approximately cylindrical in shape. A horizontally arranged main motor 3 is mounted on the support 1. The output end of the main motor 3 is connected to a stirring shaft 6 extending into the mixing tank 2. A booster pump 5 is mounted on the support 1. The output end of the booster pump 5 extends into the mixing tank 2. A microwave heater 4 is mounted on the top of the mixing tank 2. The microwave heater 4 mainly consists of a magnetron, a power inlet, and a microwave transmission window. The microwave transmission window is used to prevent the material in the mixing tank 2 from directly contacting the power inlet. The microwave output end of the microwave heater 4 faces the inside of the mixing tank 2. A stirring paddle 7 is connected to the outer wall of the stirring shaft 6. An elastic scraper 19 is connected to the stirring paddle 7. The stirring shaft 6, the stirring paddle 7, and the elastic scraper 19 are all made of non-metallic materials.
[0028] When mixing binder raw materials is required, the raw materials are added into the mixing tank 2 through the feed port 22, and then the entire equipment is started. After starting, the main motor 3 will drive the stirring shaft 6 to rotate continuously, and the stirring shaft 6 will drive the stirring paddle 7 to stir the raw materials in the mixing tank 2. During this period, the microwave heater 4 will heat the raw materials in the mixing tank 2 with microwaves, which has better heating uniformity and makes it less likely for the inner wall of the mixing tank 2 to overheat and cause adhesion, thus ensuring the final quality of the mica binder. The booster pump 5 will increase the pressure in the mixing tank 2. The pressurized environment will make it less likely for the raw materials to generate bubbles, improve the penetration efficiency between raw materials, and, together with the microwave heating environment, make the mixing effect of the mica binder better. In addition, the elastic scraper 19 will move synchronously with the stirring paddle 7, and the scraper 19 will continuously scrape the inner wall of the mixing tank 2, so that the raw materials are less likely to accumulate and stick to the inner wall of the mixing tank 2.
[0029] Reference Figures 5-7 As shown, the end of the elastic scraper 19 is inclined and abuts against the inner wall of the mixing tank 2, forming a wedge-shaped extrusion zone 20 between the scraper 19 and the inner wall of the mixing tank 2; the stirring shaft 6 is provided with a top pressure drive unit, which is used to drive the elastic scraper 19 to intermittently undergo elastic top pressure deformation towards the inner wall of the mixing tank 2. When the top pressure drive unit drives the scraper 19 to press down, the volume of the wedge-shaped extrusion zone 20 gradually decreases, generating extrusion and shearing action on the retained material. When the top pressure drive unit drives the scraper 19 to reset, the volume of the wedge-shaped extrusion zone 20 gradually increases, generating local negative pressure to promote the backfilling of new material into the wedge-shaped extrusion zone 20.
[0030] During microwave heating, microwaves form standing waves within the cavity, creating fixed energy "hot spots." The tank wall areas located on or periodically passing through these hot spots continuously experience higher energy densities, becoming preferred sites for adhesion and solidification initiation. Even if the overall average temperature is not high, localized adhesion phenomena can still occur on the tank wall.
[0031] Therefore, during the continuous scraping process of scraper 19, the material detached from the inner wall of mixing tank 2 at its end first enters the wedge-shaped extrusion zone 20 and then exits from this zone. At the same time, the top-pressure drive unit drives the elastic scraper 19 to intermittently press against the tank wall. During the top-pressure stage, the volume of the wedge-shaped extrusion zone 20 decreases, generating strong shearing and extrusion action on the material in the zone. On the one hand, it forcibly squeezes out the raw material that may be attached to the outer wall of scraper 19, preventing it from accumulating for a long time and affecting the scraping effect. At the same time, it can also compress or squeeze out the air bubbles attached to the inner wall. On the other hand, it also instantly increases the contact pressure between scraper 19 and the tank wall, enhancing the scraping force. During the reset stage, the volume of the wedge-shaped extrusion zone 20 increases and the local pressure decreases, which is conducive to the inflow of newly detached raw material. Through such periodic "top-pressure-reset" movement, scraper 19 achieves automatic cleaning of the material adhering to its own outer wall and dynamically adjusts the action pressure with the tank wall, thereby improving the adaptability and continuity of the scraping effect as a whole.
[0032] Reference Figures 5-7 As shown, the top-pressure drive unit includes a strip plate 13 that is radially slidably installed along the stirring paddle 7. The strip plate 13 is in close contact with the non-force-bearing surface of the stirring paddle 7. The scraper 19 is fixedly installed on the outer end of the strip plate 13. The stirring shaft 6 has an axially extending cavity 15 inside. The inner end of the strip plate 13 extends into the cavity 15. A plurality of circumferentially distributed top blocks 17 are arranged in the cavity 15. The inner end of the strip plate 13 is connected to a protrusion 18 corresponding to the top block 17. The protrusion 18 and the top block 17 are both semi-circular in shape. When the stirring shaft 6 rotates, the plurality of top blocks 17 periodically press against the protrusion 18. The outer wall of the mixing tank 2 is connected to an inner rod 16 that extends into the cavity 15. The plurality of top blocks 17 are all connected to the outer wall of the inner rod 16.
[0033] When the stirring shaft 6 drives the stirring paddle 7 to rotate, the strip plate 13 moves synchronously with it, causing the protrusions 18 on the strip plate 13 to move in a circular motion around the multiple fixedly arranged top blocks 17. When the protrusions 18 move to align with one of the top blocks 17, the top blocks 17 generate a radial pushing force on the protrusions 18, driving the strip plate 13 to slide laterally along the stirring paddle 7, thereby pressing the elastic scraper 19 towards the inner wall of the mixing tank 2. When the protrusions 18 disengage from the top blocks 17 as they rotate, the pushing force on the elastic scraper 19 disappears, and the scraper 19 resets under its own elasticity and pushes the strip plate 13 back to its initial position. The arrangement of multiple top blocks 17 causes the strip plate 13 to slide back and forth along the surface of the stirring paddle 7.
[0034] Reference Figures 1-2In another example, an auxiliary motor 21 is fixedly installed on the outer wall of the mixing tank 2. During operation, the rotation speed of the auxiliary motor 21 is greater than that of the main motor 3, or the rotation direction of the auxiliary motor 21 is opposite to that of the main motor 3. The output end of the auxiliary motor 21 is fixedly connected to the inner rod 16.
[0035] During use, starting the auxiliary motor 21 can drive the inner rod 16 to rotate, which in turn drives the multiple top blocks 17 fixed on it to rotate synchronously. By adjusting the speed of the auxiliary motor 21, the encounter frequency between the top block 17 and the protrusion 18 can be changed, thereby controlling the reciprocating speed of the elastic scraper 19 pressing against the inner wall of the mixing tank 2. This design realizes the dynamic adjustment of the scraping action frequency, enabling the equipment to adaptively optimize the scraping intensity and cleaning effect according to the adhesion characteristics of different materials.
[0036] Reference Figure 6 As shown, the main body of the stirring paddle 7 is a flat plate structure, and multiple first guide grooves 9 extending to the back are formed on its force-bearing surface facing the material. When the stirring shaft 6 drives the stirring paddle 7 to rotate, the material entering the first guide groove 9 flows towards the axial direction of the mixing tank 2 under the guidance of the groove wall; see reference. Figure 7 As shown, the stirring paddle 7 has multiple second guide channels 8 that are opposite in direction to the first guide channel 9. When the stirring shaft 6 drives the stirring paddle 7 to rotate, the material entering the second guide channel 8 flows towards the inner wall of the mixing tank 2 under the guidance of the channel wall. The included angle between the first guide channel 9 and the second guide channel 8 is greater than or equal to 90°.
[0037] When the agitator 7 continuously stirs in the mixing tank 2, some of the raw materials enter the first guide channel 9 and flow towards the axial region of the mixing tank 2 along its inclined direction. At the same time, another part of the raw materials enters the second guide channel 8 and flows towards the inner wall region of the mixing tank 2 in the opposite direction. The material flows with opposite directions generated by the first guide channel 9 and the second guide channel 8 converge and shear each other in the mixing tank 2, forming a strong axial and radial composite convection, thereby significantly enhancing the mixing effect of the raw materials.
[0038] Reference Figures 5-7 As shown, multiple first guide channels 9 and second guide channels 8 are arranged alternately on the surface of the stirring paddle 7, and the first guide channels 9 and the adjacent second guide channels 8 together form a guide unit.
[0039] During the mixing process, the raw materials flowing out from the first guide channel 9 will directly converge with the raw materials flowing out from the adjacent second guide channel 8 in the area near the stirring paddle 7. This continuous collision and shearing of adjacent opposite flow streams forms a high-intensity mixing zone, thereby effectively ensuring and improving the overall mixing effect.
[0040] Reference Figures 5-7As shown, the strip plate 13 has multiple equally spaced slots 14 along its length. The opening area of the slots 14 is greater than or equal to the sum of the opening areas of the first guide channel 9 and the second guide channel 8. When the strip plate 13 slides, the slots 14 can be aligned with the output end of the first guide channel 9, the output end of the second guide channel 8, or both output ends simultaneously, thereby dynamically switching the guiding and confluence paths of the material.
[0041] During the stirring process, the reciprocating sliding strip plate 13 dynamically changes the alignment state between the slot 14 and the guide channel: when the slot 14 is connected to the first guide channel 9 alone (e.g.) Figure 6 As shown), the raw materials are mainly guided towards the axis of the mixing tank 2; when it is connected separately to the second guide channel 8 (as shown), the raw materials are mainly guided towards the axis of the mixing tank 2. Figure 7 As shown), the raw materials are mainly guided towards the inner wall of the mixing tank 2. When the slot 14 is connected to the first guide slot 9 and the second guide slot 8 at the same time, the two opposite raw material flows directly converge and mix at the slot 14. Thus, through the continuous reciprocating motion of the strip plate 13, the guiding direction and convergence state of the slot 14 are periodically switched, causing the material flow field to produce continuous changes in direction and intensity, thereby breaking the mixing settling and further improving the uniformity and efficiency of mixing.
[0042] Reference Figure 8 As shown, multiple guide blocks 10 are fixedly connected to the force-bearing surface of the stirring paddle 7. Each guide block 10 has two symmetrically arranged guide slopes 11. The two guide slopes 11 together form a wedge-shaped flow guiding structure. The shape of the guide block 10 is similar to a triangle. When the guide block 10 rotates with the stirring paddle 7, the guide slopes 11 can divert the incoming material to both sides of the stirring paddle 7.
[0043] During the mixing process, the guide block 10 fixed on the stirring paddle 7 diverts the incoming raw material to both sides of the axis of the stirring shaft 6 through its symmetrically arranged guide slope 11. This design guides the raw material into the area between the axially adjacent stirring paddles 7, forming an axial circulation. This axial flow is coupled with the radial flow generated by the first guide groove 9 and the second guide groove 8, creating a complex three-dimensional convection field in the mixing tank 2, thereby significantly improving the mixing intensity and uniformity of the raw material.
[0044] Reference Figure 6 and Figure 7 As shown, a feeding channel 12 is formed between two adjacent guide blocks 10. The inlet ends of the first guide groove 9 and the second guide groove 8 are both located in the feeding channel 12. During the stirring process of the guide block 10 following the stirring paddle 7, the raw material will enter the first guide groove 9 and the second guide groove 8 through the feeding channel 12.
