Description

Technical Field

[0001] The present invention relates to the technical field of removing bubbles from viscous fluids, and in particular to an environmental protection device for removing bubbles from viscous fluids. Background Art

[0002] There is a viscous force in viscous fluids, which is mainly caused by intermolecular forces: when two adjacent layers of fluid slide relative to each other or undergo shear deformation, due to the interaction between fluid molecules, shear stress will be generated in the opposite direction to prevent the relative sliding or shear deformation of the fluid. Simply put, viscosity refers to the ability of a fluid to resist shear deformation. The greater the viscosity, the stronger the ability to resist the action of an external shear force.

[0003] There are many common types of viscous fluids. During the production and manufacturing process of many viscous fluids, their raw materials need to be mixed and heated, etc. Bubbles may be generated inside during processing. For example, when manufacturing glue, there are bubbles in the glue, which may affect its viscosity after curing. Therefore, it is necessary to remove the bubbles inside, and thus an environmental protection device for removing bubbles from viscous fluids is required to remove the bubbles inside.

[0004] Currently, the commonly used methods for removing bubbles include the heating method, the vacuum method, etc., but they are all for fluids that conform to Newton's law. Some polymer fluids do not conform to Newton's law. For example, polymer glue. Therefore, when stirring to remove bubbles under vacuum conditions, the fluidity of polymer glue is poor, which may affect the efficiency of removing bubbles. Summary of the Invention

A first gap is arranged between the flow limiting cone platform and the rotating shaft, and a cutting ring is arranged at the lower end of the flow limiting cone platform.

[0011] To prevent the fluid body on the flow limiting cone platform from splashing, preferably, a diversion plate is fixedly connected between the conical plate and the flow limiting cone platform. The diversion plate is communicated with the second diversion groove, and baffle plates matching the diversion plate are symmetrically arranged on both sides of the diversion plate. A diversion groove matching the diversion plate is arranged on the flow limiting cone platform.

[0012] To facilitate the decrease in the thickness of the fluid body on the flow guide plate, preferably, a third converging area and a third extending area are provided on the flow guide plate. Among them, the third extending area is arranged at one end of the flow guide plate close to the second flow guide groove, and the width of the third extending area is greater than the width of the third converging area.

[0013] To facilitate the fluid body on the flow guide plate to enter the second flow guide groove, preferably, one end of the flow guide plate close to the second flow guide groove is arranged in the middle of the second flow guide groove.

[0015] To facilitate the circulation of the fluid body, preferably, the flow guide assembly includes a flow guide square pipe fixedly arranged on the conical plate in a circular shape. The flow guide square pipe is attached to the inner wall of the inner barrel. A square groove is arranged in the flow guide square pipe, and the square groove is communicated with the second flow guide groove, and the square groove is arranged on the side close to the inner barrel.

[0016] To facilitate the delivery of the fluid body with removed bubbles to the bottom of the inner barrel, preferably, the flow guide assembly wraps a flow guide spiral pipe fixedly arranged on the conical plate in a circular shape. The flow guide spiral pipe is attached to the inner wall of the inner barrel. A spiral groove is arranged in the flow guide spiral pipe. The spiral groove is arranged on the side close to the inner barrel, and the spiral direction of the flow guide spiral pipe matches the rotation direction of the rotating shaft.

[0017] Compared with the prior art, the present invention provides an environmental protection device for removing bubbles from viscous fluids, and has the following beneficial effects:

[0018] 1. For the environmental protection device for removing bubbles from viscous fluids, the contact area between the upward-climbing fluid body and the vacuum cavity becomes larger. The bubbles in the fluid body within a certain thickness in contact with the vacuum cavity move towards the vacuum cavity under the action of pressure until they burst and the bubbles are removed. Thus, the contact area between the fluid body and the vacuum cavity is effectively increased, and further, the efficiency of removing bubbles in the polymer fluid body is effectively improved.

[0019] 2. The environmental protection device for removing bubbles from viscous fluid, by contacting and cooperating with the conical plate, under the action of the pressure generated by the accumulation of the fluid body and its own gravity, overcomes part of the centripetal force, and makes it flow into the diversion square pipe along the diversion groove. The fluid body flows downward along the square groove. At this time, the high-molecular fluid body presents a phenomenon of tubeless siphon, driving the fluid body in the diversion groove to flow downward continuously. When it flows to the bottom of the inner barrel, it will continue to circulate under the action of the climbing rod effect. When the fluid body flows along the diversion groove, the fluid body contacts the vacuum cavity again, thus effectively improving the contact efficiency between the fluid body and the vacuum cavity, and further effectively improving the efficiency of bubble removal.

[0020] 3. The environmental protection device for removing bubbles from viscous fluid, after the fluid body accumulates and deforms in the transfer cavity, is re-laid into the first diversion groove through the first gathering area, and it flows into the second diversion groove along the first diversion groove. Since the width of the first gathering area is smaller than the width of the second extension area, when the fluid body flows towards the second extension area, the thickness of the fluid body gradually decreases, making it spread out and laid in the first diversion groove and the second diversion groove, thus effectively improving the contact efficiency between the fluid body flowing in the first diversion groove and the second diversion groove and the vacuum cavity, and further effectively improving the efficiency of removing bubbles in the fluid body.

[0021] 4. The environmental protection device for removing bubbles from viscous fluid, the fluid body climbs upward along the rotating shaft, and its diameter gradually becomes smaller. The fluid body on the outer side of the rotating shaft after contacting the vacuum cavity is cut by the cutting ring on the flow-limiting cone platform, and is shunted to form a first sub-fluid and a second sub-fluid. At the same time, the first sub-fluid flows upward into the transfer cavity through the first gap, thus effectively preventing a large amount of fluid body from accumulating in the transfer cavity and affecting the conveying effect of the first diversion groove and the second diversion groove, and effectively preventing the fluid body with most bubbles removed from affecting the bubble removal effect of the fluid body in the first diversion groove.

[0022] The parts not involved in this device are the same as the prior art or can be implemented by the prior art. The present invention effectively increases the contact area between the fluid body and the vacuum cavity, thereby effectively improving the efficiency of removing bubbles in the high-molecular fluid body, and effectively preventing the fluid body with most bubbles removed from affecting the bubble removal effect of the fluid body in the first diversion groove.

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0040] Example 1: Refer to Figure 1 、 Figure 2 and Figure 3, An environmentally friendly device for removing air bubbles from viscous fluids, comprising: a vacuum barrel 1, a sealing cover 101 and a vacuum pump 102. The sealing cover 101 is threadedly connected to the upper end of the vacuum barrel 1, and the air extraction end of the vacuum pump 102 is communicated with the inside of the vacuum barrel 1. It further comprises: an inner barrel 106, fixed inside the vacuum barrel 1, and the upper end of the inner barrel 106 is communicated with the inside of the vacuum barrel 1; a motor 105, fixed on the sealing cover 101; a rotating shaft 2, fixed to the output end of the motor 105; a conical plate 3, fixed on the rotating shaft 2, and the conical plate 3 is coaxially arranged with the rotating shaft 2; a constant pressure groove 301, circumferentially formed on the conical plate 3; a stirring disk 201, fixed to the bottom end of the rotating shaft 2; a baffle plate 202, circumferentially fixed on the upper end of the stirring disk 201; a transfer cavity 302, arranged on the lower side of the conical plate 3 and at one end close to the rotating shaft 2, and a plurality of diversion grooves communicating with the transfer cavity 302 are circumferentially formed on the conical plate 3; a plurality of diversion components, circumferentially fixed on the conical plate 3, and the diversion components are in contact with the inner wall of the inner barrel 106. The side of the diversion component close to the inner barrel 106 is a cavity, and there is a certain gap between the bottom end of the diversion component and the bottom end of the inner barrel 106. The diversion component is communicated with the diversion groove. When the rotating shaft 2 rotates, the fluid body 7 flows upward into the transfer cavity 302 through the climbing rod effect, flows into the diversion component through the diversion groove, and finally flows to the bottom of the vacuum barrel 1 to realize the circulating flow of the fluid body 7.

[0041] A baffle 103 matching the inner barrel 106 is fixedly connected to the sealing cover 101. Communication ports 104 are symmetrically formed on the baffle 103, and the rotating shaft 2 rotates in a sealed manner on the baffle 103.

[0042] The diversion component includes a diversion square tube 5 circumferentially fixed on the conical plate 3. The diversion square tube 5 is in contact with the inner wall of the inner barrel 106. A square groove 501 is arranged inside the diversion square tube 5, and the square groove 501 is communicated with the second diversion groove 304, and the square groove 501 is arranged on the side close to the inner barrel 106.

[0043] When removing air bubbles from high molecular glue or high molecular fluid, the fluid body 7 is placed into the inner barrel 106, and then the sealing cover 101 is threadedly connected into the vacuum barrel 1. At this time, the baffle 103 enters the inner side of the upper end of the inner barrel 106 to fix the upper end of the inner barrel 106, thereby preventing the inner barrel 106 and the rotating shaft 2 from shaking when the rotating shaft 2 rotates. The vacuum pump 102 is turned on, and the vacuum pump 102 extracts vacuum from the inside of the vacuum barrel 1 and keeps it in a high vacuum state all the time.

[0044] Turn on the motor 105. The motor 105 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the stirring disk 201 and the baffle 202 to rotate along the axis of the rotating shaft 2, causing the fluid body 7 in the inner barrel 106 to rotate. The polymeric fluid body 7 is elastic and is generated due to the formation of an anisotropic structure during the flow of the fluid body 7. When rotating, the elastic macromolecular chains will be oriented along the circumferential direction and undergo tensile deformation, thereby generating a pressure towards the axis of the rotating shaft 2. The shear rate is greater closer to the axis, so the normal stress is greater. Correspondingly, the elastic restoring force of the polymeric chains is greater, causing the liquid to be squeezed upwards along the axis, resulting in the rod climbing phenomenon and thus generating the rod climbing effect. At this time, the contact area between the upward climbing fluid body 7 and the vacuum cavity becomes larger, and the bubbles in the fluid body 7 within a certain thickness in contact with the vacuum cavity move towards the vacuum cavity under the action of pressure until they burst and the bubbles are removed, effectively increasing the contact area between the fluid body 7 and the vacuum cavity, and thus effectively improving the efficiency of bubble removal in the polymeric fluid body 7.

[0045] Among them, the upward flowing fluid body 7 finally gathers in the transfer cavity 302 as it moves upwards, and then flows into the diversion groove under the action of centrifugal force. At this time, through the contact and cooperation with the conical plate 3, under the action of the pressure generated by the accumulation of the fluid body 7 and its own gravity, part of the centripetal force is overcome, and it flows along the diversion groove into the diversion square pipe 5. The fluid body 7 flows downwards along the square groove 501. At this time, the polymeric fluid body 7 exhibits the phenomenon of siphon without a pipe, driving the fluid body 7 in the diversion groove to continuously flow downwards. When it flows to the bottom of the inner barrel 106, it will continue to circulate under the action of the rod climbing effect. When the fluid body 7 flows along the diversion groove, the fluid body 7 comes into contact with the vacuum cavity again, effectively increasing the contact efficiency between the fluid body 7 and the vacuum cavity, and thus effectively improving the efficiency of bubble removal.

[0046] It should be noted that the fluid body 7 refers to a polymeric non-Newtonian viscous fluid.

[0047] Example 2: Refer to Figure 3 、 Figure 4 、 Figure 13 and Figure 14 , an environmental protection device for removing bubbles from viscous fluids, which is basically the same as Example 1. Further, the diversion groove includes a first diversion groove 303 and a second diversion groove 304. The first diversion groove 303 is communicated with the second diversion groove 304, and the first diversion groove 303 is arranged at one end of the conical plate 3 close to the transfer cavity 302. A first gathering area 305 is arranged at one end of the first diversion groove 303 close to the transfer cavity 302. A second extension area 308 is arranged at one end of the second diversion groove 304 far from the first diversion groove 303. The width of the first gathering area 305 is smaller than the width of the second extension area 308.

[0048] Both the first diversion groove 303 and the second diversion groove 304 are arc-shaped.

[0049] When the fluid body 7 accumulates and deforms in the transfer cavity 302, it is re-laid into the first diversion groove 303 through the first converging area 305, and flows along the first diversion groove 303 into the second diversion groove 304. Since the width of the first converging area 305 is smaller than the width of the second extension area 308, when the fluid body 7 flows towards the second extension area 308, the thickness of the fluid body 7 gradually decreases, causing it to spread out and be laid in the first diversion groove 303 and the second diversion groove 304. This effectively improves the contact efficiency between the fluid body 7 flowing in the first diversion groove 303 and the second diversion groove 304 and the vacuum cavity, and thus effectively improves the efficiency of removing bubbles in the fluid body 7.

[0050] Example 3: Refer to Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 An environmental protection device for removing bubbles from a viscous fluid, which is basically the same as Example 1. Further, a flow-limiting frustum 4 is provided on the conical plate 3. A first gap 401 is provided between the flow-limiting frustum 4 and the rotating shaft 2, and a cutting ring 402 is provided at the lower end of the flow-limiting frustum 4.

[0051] Under the climbing effect, the fluid body 7 climbs upward along the rotating shaft 2, and its diameter gradually becomes smaller. The fluid body 7 in contact with the vacuum cavity outside the rotating shaft 2 is cut by the cutting ring 402 on the flow-limiting frustum 4 for diversion, forming a first sub-fluid 701 and a second sub-fluid 702. At the same time, the first sub-fluid 701 flows upward through the first gap 401 into the transfer cavity 302, effectively preventing a large amount of the fluid body 7 from accumulating in the transfer cavity 302 and affecting the conveying effect of the first diversion groove 303 and the second diversion groove 304, and effectively preventing the fluid body 7 that has removed most of the bubbles from affecting the bubble removal effect of the fluid body 7 in the first diversion groove 303.

[0052] Example 4: Refer to Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 、 Figure 11 and Figure 12, an environmental protection device for removing bubbles from a viscous fluid, is basically the same as Example 1, and further, a guide plate 404 is fixedly connected between the conical plate 3 and the flow limiting cone 4, the guide plate 404 is connected to the second guide groove 304, and baffle plates 407 matching the guide plate 404 are symmetrically arranged on both sides of the guide plate 404, and a drainage groove 403 matching the guide plate 404 is arranged on the flow limiting cone 4.

[0053] The guide plate 404 is arranged in an arc shape, and the middle part of the guide plate 404 bulges upward.

[0054] The second diverter fluid 702 gathers in the drainage groove 403, and then flows along the guide plate 404 toward the second guide groove 304, so that it is laid on the first diverter fluid 701 in the second guide groove 304, and is centrally transported to the guide square tube 5 for circulation. After the second diverter fluid 702 on the guide plate 404 is guided and transformed by the drainage groove 403, it continues to contact the vacuum cavity to remove bubbles, thereby effectively improving the efficiency of bubble removal.

[0055] In addition, the arc-shaped guide plate 404 makes the thickness of the second diverter fluid 702 in the middle section relatively thick, so that the first diverter fluid 701 in the second guide groove 304 can drive the second diverter fluid 702 to flow. The flow mode is due to centrifugal force on the one hand, and on the other hand, it drives the second diverter fluid 702 to flow through the principle of tubeless siphon.

[0056] Example 5: Reference Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , an environmental protection device for removing bubbles from a viscous fluid, is basically the same as Example 1, and further, a third gathering area 405 and a third extension area 406 are provided on the guide plate 404, wherein the third extension area 406 is provided at one end of the guide plate 404 close to the second guide groove 304, and the width of the third extension area 406 is greater than the width of the third gathering area 405.

[0057] The second flow divider 702 flowing on the guide plate 404 flows from the third gathering area 405 to the third extension area 406 , so that the second flow divider 702 is flattened to contact the vacuum chamber, thereby effectively improving the effect of removing residual bubbles in the second flow divider 702 .

[0058] When the second split fluid 702 with a thicker accumulation in the middle of the arc-shaped guide plate 404 moves toward the third extension area 406 , it flows to both sides, thereby effectively improving the flattening efficiency of the second split fluid 702 and further effectively improving the bubble removal efficiency in the second split fluid 702 .

[0059] Example 6: Refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 . The environmental protection device for removing bubbles from viscous fluids is basically the same as that in Example 1. Further, one end of the flow guide plate 404 close to the second flow guide groove 304 is arranged in the middle of the second flow guide groove 304.

[0060] The upper side of the flow guide plate 404 limits the first sub-fluid 701 in the first flow guide groove 303, effectively improving the uniformity of the first sub-fluid 701 entering the second flow guide groove 304 from the first flow guide groove 303. At this time, the second sub-fluid 702 on the flow guide plate 404 is laid on the first sub-fluid 701 in the second flow guide groove 304, and the second sub-fluid 702 is located in the second flow guide groove 304, thereby effectively preventing the second sub-fluid 702 from splashing.

[0061] Example 7: Refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , Figure 11 and Figure 12 . The environmental protection device for removing bubbles from viscous fluids is basically the same as that in Example 1. Further,

[0062] A first extension area 306 is arranged at one end of the first flow guide groove 303 away from the first converging area 305, a second converging area 307 is arranged at one end of the second flow guide groove 304 away from the second extension area 308, the first extension area 306 is communicated with the second converging area 307, and a flow guide fillet 309 is arranged at the connection between the first flow guide groove 303 and the second flow guide groove 304.

[0063] The first sub-fluid 701 in the transfer cavity 302 flows into the diversion square pipe 5 successively through the first converging area 305, the first extending area 306, the second converging area 307, and the second extending area 308. When the first sub-fluid 701 flows from the first converging area 305 to the first extending area 306, the first sub-fluid 701 undergoes the first flat spreading and extension to improve the bubble removal efficiency of the first sub-fluid 701. When the first sub-fluid 701 flows from the first extending area 306 to the second converging area 307, the first sub-fluid 701 converges and flows in cooperation with the flow guide plate 404, so that the converged first sub-fluid 701 adheres to the second sub-fluid 702 on the flow guide plate 404, and drives the second sub-fluid 702 to flow under the action of siphon without a pipe. The converged first sub-fluid 701 effectively improves the flow efficiency of the second sub-fluid 702. When the first sub-fluid 701 with the second sub-fluid 702 laid on its surface flows from the second converging area 307 to the second extending area 308, the first sub-fluid 701 begins to spread and flatten. At this time, it pulls the second sub-fluid 702 at the upper end to spread to both sides, reducing its thickness, effectively improving the contact efficiency between the second sub-fluid 702 and the vacuum cavity, and further effectively improving the bubble removal efficiency of the fluid body 7.

[0064] Embodiment 8: As another implementation manner of the diversion device, refer to Figure 15 , the diversion assembly wraps and fixedly holds the diversion spiral pipe 6 circumferentially fixed on the conical plate 3, and the diversion spiral pipe 6 is in contact with the inner wall of the inner barrel 106. A spiral groove 601 is provided in the diversion spiral pipe 6, and the spiral groove 601 is arranged on the side close to the inner barrel 106, and the spiral direction of the diversion spiral pipe 6 matches the rotation direction of the rotating shaft 2.

[0065] Using the diversion spiral pipe 6 as the diversion assembly, when the rotating shaft 2 drives the diversion spiral pipe 6 to rotate, the fluid body 7 in the second diversion groove 304 enters the spiral groove 601, so that the fluid body 7 in the spiral groove 601 can flow downward, effectively improving the circulation efficiency of the fluid body 7, and further effectively improving the bubble removal efficiency of the fluid body 7. Moreover, the spiral diversion spiral pipe 6 effectively reduces the resistance between it and the fluid body 7.

[0066] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
