Description

Technical Field

[0001] The present application relates to the technical field of polymer material mixing equipment, and in particular to a high-efficiency mixing device for synthesizing high-temperature resistant block polysulfate esters. Background Art

[0002] With the continuous development of materials science and technology, high-temperature resistant block polysulfate esters have shown great application potential in many high-end fields due to their unique properties. For example, the demand for high-temperature resistant and high-performance materials in industries such as aerospace, electronics and electrical appliances is growing, which has prompted in-depth research and development of its synthesis process and related equipment.

[0003] However, most of the existing mixing devices for synthesizing high-temperature resistant block polysulfate esters improve stirring efficiency by increasing the number of stirring rods. Although simply increasing the number of stirring rods can enhance stirring intensity to a certain extent, it is easy to cause stirring dead zones, that is, the stirring effect in some areas is poor, resulting in uneven mixing of raw materials. At the same time, it is also difficult to circulate the raw materials at the bottom and upper parts of the liquid storage barrel through the stirring rods, further reducing the mixing efficiency of the raw materials. At the same time, when adding additives, most of the existing mixing devices for synthesizing high-temperature resistant block polysulfate esters directly pour them from the upper part of the liquid storage barrel, and then in the initial stage of mixing, the additives diffuse rapidly on the surface of the raw materials, which easily leads to the occurrence of local excessive concentration or instability. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes an efficient mixing device for the synthesis of high temperature resistant block polysulfuric acid esters, which uses a single servo motor to synchronously control the overall driving element, thereby achieving efficient mixing and accurate addition of additives. The device has a high degree of automation, a reasonable and compact structure, and is convenient for use by staff. While controlling the circular sealing plate and the annular sealing plate to move up and down, the additive inside the feeding tube can also be circulated and quantitatively entered into the second pipette, effectively avoiding the one-time large-scale injection of the additive or the unstable addition amount, thereby ensuring the stability of the entire synthesis reaction process.

The intermediate tube 310 is located at the upper part of the sealing annular plate 229, and the interior of the transfer cover 306 is slidably connected with a small negative pressure circular plate 311, and the middle part of the lower surface of the small negative pressure circular plate 311 is fixedly connected with a first transfer rod 312, and the lower end of the inside of the feeding tube 301 is slidably connected with a large negative pressure circular plate 314, and the middle part of the lower surface of the large negative pressure circular plate 314 is fixedly connected with a second transfer rod 315, and the first transfer rod 312 and the second transfer rod 315 are connected. 15 is fixedly connected with a rectangular connecting plate 313 on the lower surface, the plate body of the large negative pressure circular plate 314 is provided with a bottom-through small one-way valve 316, the upper end of the feeding cylinder 301 is fixedly connected with a feeding cover 302, and the upper end of the feeding cover 302 is hingedly connected with a sealing cover 303. Specifically, during the descending process of the reciprocating slider 204, the third connecting rod 309 is also driven to descend. When the reciprocating slider 204 is about to descend to the bottom of the reciprocating screw 203, the lower end of the third connecting rod 309 will contact the upper surface of the annular connecting plate 308 and press the annular connecting plate 308 downward. At this time, the air between the annular plate 229 and the annular connecting plate 308 is squeezed and discharged into the interior of the transfer cover 306 through the intermediate pipe 310. At this time, the air pressure inside the transfer cover 306 begins to The small negative pressure circular plate 311 is increased and squeezed so that the small negative pressure circular plate 311 drives the first transfer rod 312 and the rectangular connecting plate 313 to move downward, and the large negative pressure circular plate 314 is moved downward under the action of the second transfer rod 315, wherein, before the large negative pressure circular plate 314 moves downward, the added material inside the adding barrel 301 will flow into the bottom of the adding barrel 301 through the downward-through small one-way valve 316. At this time, when the large negative pressure circular plate 314 moves downward, the added material at the bottom of the adding barrel 301 will not be able to flow back to the upper part of the large negative pressure circular plate 314 through the downward-through small one-way valve 316. Therefore, in the process of the large negative pressure circular plate 314 moving downward, the pressure value at the bottom of the adding barrel 301 will reach the set pressure of the pressure valve 305, and the pressure valve 305 will open at this time.At this time, the added material at the bottom of the adding cylinder 301 enters the interior of the second liquid suction pipe 218 through the connecting pipe 304 under the action of pressure. At the same time, when the reciprocating slider 204 descends, the annular sealing plate 212 will also be driven to descend, and then the second liquid suction pipe 218 will also absorb liquid under the action of negative pressure, so that the added material will first enter the interior of the mixing cylinder 208, and then be sprayed out from the lower liquid collecting ring 206 and the interior of the second liquid flow nozzle 221. When the reciprocating slider 204 moves upward, the third connecting rod 309 will not be able to press down the annular connecting plate 308, and then under the action of the short reset spring 307, the small negative pressure circular plate 311 and the large negative pressure circular plate 312 can be pressed down. The plate 314 returns to its original position. At this time, the large negative pressure circular plate 314 moves upward to form a negative pressure at the bottom of the feeding tube 301, and then a part of the added material is sucked from the inside of the feeding tube 301 again through the small check valve 316, thereby realizing the intermittent feeding function, and the added material is sprayed out from the bottom of the liquid storage barrel 101, and mixed with the original raw materials in the liquid storage barrel 101 at the bottom, further promoting the overall mixing uniformity, and reducing the local concentration too high or unstable phenomenon that may be caused by the rapid diffusion of the added material on the surface at the initial stage of mixing. Among them, the servo motor 202 is controlled to make the reciprocating slider 204 move on the outer wall of the reciprocating screw 203 The first part of the invention is to make the first suction pipe 214 suck the raw material from the bottom and the second suction pipe 218 suck the raw material from the top, and then discharge the raw material to the opposite direction through the corresponding first discharge pipe 216 and the second discharge pipe 220, so that the raw material circulates in different areas, which greatly improves the mixing efficiency, can make the raw material mixed evenly in a short time, reduce the mixing time, and improve the production efficiency. Secondly, while controlling the circular sealing plate 210 and the annular sealing plate 212 to move up and down, the added material in the feeding cylinder 301 can also be circulated and quantitatively entered into the second suction pipe 218, which effectively avoids the one-time large amount of added material. The amount of injection or the amount of addition is unstable, thereby ensuring the stability of the entire synthesis reaction process. Thirdly, the additive is sprayed out from the position of the lower liquid collecting ring 206 under the extrusion of the annular sealing plate 212, and then the additive is sprayed out intermittently from the bottom and mixed with the raw materials, avoiding the local concentration being too high or unstable due to the rapid diffusion of the additive on the surface at the beginning of mixing. Fourthly, the whole driving element is synchronously controlled by a single servo motor 202, which realizes efficient mixing and accurate addition of additives. At the same time, it has a high degree of automation, a reasonable and compact structure, and is easy for staff to use.

The end of the long rotating rod 407 close to the mixing cylinder 208 is fixedly connected to the second bevel gear 408. The first bevel gear 406 and the second bevel gear 408 are meshed with each other. The outer wall of the rod body of the long rotating rod 407 is fixedly connected to a plurality of stirring blades 409, and a plurality of positioning frames 410 are fixedly connected to the edge of the inner top surface of the top cover 102. The lower end of the positioning frame 410 is slidably connected to a limited bearing sleeve 411, and the end of the long rotating rod 407 away from the mixing cylinder 208 is fixedly connected to the inner wall of the limited bearing sleeve 411.

[0056] Specifically, the working principle of the high-efficiency mixing device for synthesizing high-temperature resistant block polysulfate esters is as follows: in the process of mixing high-temperature block polysulfate esters, the servo motor 202 is first started to rotate the reciprocating screw 203, and the reciprocating slider 204 begins to move upward on the outer wall of the reciprocating screw 203, so that the first connecting rod 226 drives the circular sealing plate 210 to move upward inside the mixing tube 209. At this time, the bottom of the circular sealing plate 210 begins to be in a negative pressure state, and the raw materials are sucked from the lower end of the liquid storage barrel 101 through the first suction pipe 214 and the first suction nozzle 215. In the process of the circular sealing plate 210 rising, the inside of the mixing tube 209 will gradually be filled with raw materials. At this time, the reciprocating slider 204 moves to the reciprocating screw 203. When the top moves downward again, the first connecting rod 226 drives the circular sealing plate 210 to move downward inside the mixing tube 209. At this time, the raw material inside the mixing tube 209 will pass through the upper one-way valve 211 and flow from the lower part of the circular sealing plate 210 to the upper part of the circular sealing plate 210. Among them, the raw material inside the mixing tube 209 cannot flow back to the interior of the first suction tube 214 under the action of the first right inlet one-way valve 222. At this time, the raw material inside the mixing tube 209 can only flow into the upper part of the circular sealing plate 210 through the upper one-way valve 211. When the circular sealing plate 210 moves to its original position and moves upward again, the raw material on the upper part of the circular sealing plate 210 is squeezed during the upward movement of the circular sealing plate 210, and the circular sealing plate The raw materials at the top of 210 can only flow into the interior of the upper liquid collecting ring 205 through the first left inlet non-return valve 223 and the first liquid discharge pipe 216, and then be sprayed out from the edge of the upper part of the liquid storage barrel 101 to the outside by multiple first liquid flow nozzles 217. During the rising process of the circular sealing plate 210, the liquid can be sucked into the mixing liquid pipe 209 again through the first liquid suction pipe 214 and the first liquid suction nozzle 215. This cycle is repeated to achieve the purpose of flowing the raw materials at the bottom of the liquid storage barrel 101 to the upper part. At the same time, during the reciprocating movement of the outer wall of the reciprocating screw 203 by the reciprocating slider 204, the reciprocating slider 204 will also synchronously drive the second connecting rod 227 and the annular sealing plate 212 to move up and down. During the downward movement of the annular sealing plate 212, the upper end of the mixing liquid cylinder 208 will generate Negative pressure is generated, and the raw materials on the upper part of the liquid storage barrel 101 are sucked through the second suction pipe 218 and the second suction nozzle 219. When the annular sealing plate 212 moves downward to the bottom and then moves upward, the raw materials inside the mixing cylinder 208 will flow into the lower part of the annular sealing plate 212 under the action of the lower large one-way valve 213, wherein, under the action of the second right inlet one-way valve 224, the raw materials inside the mixing cylinder 208 cannot flow back to the interior of the second suction pipe 218, and under the coordinated action of the second discharge pipe 220 and the second left inlet one-way valve 225, the raw materials flow from the lower end of the mixing cylinder 208 to the lower liquid collecting ring 206, and then sprayed to the lower part of the liquid storage barrel 101 through multiple second flow nozzles 221. In this way, through the up and down reciprocating motion of the annular sealing plate 212,A circulation process of transferring the raw materials from the upper part of the liquid storage barrel 101 to the lower part is realized. In this process, the first suction pipe 214 sucks the raw materials from the lower part of the liquid storage barrel 101, and the second suction pipe 218 sucks the raw materials from the upper part of the liquid storage barrel 101, and the first discharge pipe 216 discharges the raw materials sucked by the first suction pipe 214 to the upper part of the liquid storage barrel 101, and the second discharge pipe 220 discharges the raw materials sucked by the second suction pipe 218 to the lower part of the liquid storage barrel 101, thereby achieving the effect of all-round mixing of the raw materials inside the liquid storage barrel 101. At the same time, during the descending process of the reciprocating slider 204, the third connecting rod 309 will also be driven to descend. When the reciprocating slider 204 is about to descend to the bottom of the reciprocating screw 203, the lower end of the third connecting rod 309 will contact the annular connecting rod 203. The upper surface of the plate 308 contacts and presses the annular connecting plate 308 downward. At this time, the air blocking the annular plate 229 and the annular connecting plate 308 is squeezed and discharged into the interior of the transfer cover 306 through the intermediate tube 310. At this time, the air pressure inside the transfer cover 306 begins to increase and squeezes the small negative pressure circular plate 311, so that the small negative pressure circular plate 311 drives the first transfer rod 312 and the rectangular connecting plate 313 to move downward, and under the action of the second transfer rod 315, the large negative pressure circular plate 314 moves downward. Among them, when the large negative pressure circular plate 314 has not moved downward, the added material inside the adding barrel 301 will flow into the bottom of the adding barrel 301 through the downward-through small one-way valve 316. At this time, when the large negative pressure circular plate 314 moves downward, the added material at the bottom of the adding barrel 301 will The liquid cannot flow back to the upper part of the large negative pressure circular plate 314 through the small check valve 316. As a result, during the downward movement of the large negative pressure circular plate 314, the pressure value at the bottom of the feeding cylinder 301 will reach the set pressure of the pressure valve 305. At this time, the pressure valve 305 opens. At this time, the added material at the bottom of the feeding cylinder 301 enters the interior of the second liquid suction pipe 218 through the connecting pipe 304 under the action of pressure. At the same time, when the reciprocating slider 204 descends, the annular sealing plate 212 will also be driven to descend. Then, the second liquid suction pipe 218 will also absorb liquid under the action of negative pressure, so that the added material will first enter the interior of the mixing cylinder 208, and then be ejected from the lower liquid collecting ring 206 and the interior of the second liquid flow nozzle 221. When the reciprocating slider 204 moves upward, the third connecting rod 309 The annular connecting plate 308 cannot be pressed down, and then under the action of the short return spring 307, the small negative pressure circular plate 311 and the large negative pressure circular plate 314 can return to their original positions. At this time, the large negative pressure circular plate 314 moves upward and forms a negative pressure at the bottom of the feeding tube 301, and then a part of the additive is sucked from the inside of the feeding tube 301 again through the small check valve 316, thereby realizing the intermittent feeding function, and the additive is sprayed out from the bottom of the liquid storage barrel 101, and mixed with the original raw materials in the liquid storage barrel 101 at the bottom, further promoting the overall mixing uniformity, and reducing the local concentration too high or unstable phenomenon that may be caused by the rapid diffusion of the additive on the surface in the initial mixing stage. In addition, during the reciprocating motion of the reciprocating slider 204 on the outer wall of the reciprocating screw 203,The fixed frame 401 will move up and down with the movement of the reciprocating slider 204, thereby driving the special-shaped connecting frame 402 to move synchronously. When the special-shaped connecting frame 402 moves upward, the tooth plate 403 on the outer wall of the mixing cylinder 208 and the tooth cylinder 405 on the short rotating rod 404 mesh with each other, causing the short rotating rod 404 to rotate, and the first bevel gear 406 on both sides of the short rotating rod 404 and the second bevel gear 408 at one end of the long rotating rod 407 mesh with each other, thereby driving the long rotating rod 407 to rotate. The stirring blade 409 on the outer wall of the rod body of the long rotating rod 407 stirs the raw materials inside the liquid storage barrel 101 with the rotation of the long rotating rod 407 until the raw materials are fully mixed in the liquid storage barrel 101 to meet the expected requirements, and then the discharge valve pipe 106 is opened, and the mixed liquid is smoothly discharged from the bottom of the liquid storage barrel 101 under the action of gravity, thereby completing the entire workflow of the high-efficiency mixing device for the synthesis of high-temperature resistant block polysulfate esters.
