Description

Technical Field

[0001] The present invention relates to the technical field of chemical material production, and more specifically, to a production device and method for high-silicon-content Si-Pc materials based on the batch process. Background Art

[0002] The batch production of high-silicon-content Si-PC (silicone copolymer polycarbonate) materials is a discontinuous production method, suitable for the production of small batches and diverse product requirements. By strictly controlling the reaction parameters, multiple physical and chemical processing steps are gradually completed to prepare high-silicon-content Si-PC materials with excellent hydrolysis resistance, good flame retardancy, and good thermal stability.

[0003] The patent with the application number CN202010375137.0 discloses a glass fiber reinforced PC material that can be ultrasonically welded and its preparation method, which relates to PC materials. A styrene-acrylonitrile copolymer is added to the glass fiber reinforced PC material for polymerization modification, which reduces the melting point of the material while ensuring its toughness and strength; and a Si-PC copolymer is added to improve the ductility of the material, so that the impact toughness of the brittle glass fiber reinforced PC is improved, and it has good weldability and good chemical resistance.

[0004] However, in the mass production process of traditional high-silicon-content Si-Pc materials, the current batch reaction process is adopted. It is necessary to wait for the previous batch reaction to complete and thoroughly clean the reaction kettle before feeding the new batch. Since the reaction kettle needs to be heated to the high temperature range of 280 - 320 °C each time it operates, and the subsequent cooling and cleaning take a long time, the effective utilization rate of the equipment is low, and the production process is discontinuous. In addition, after the reaction in the existing reaction kettle is complete, an additional pressurization device needs to be configured to cooperate with the cleaning nozzle to clean the inside of the reaction kettle, and the overall automation degree of the reaction equipment is not high.

[0005] In view of this, we propose a production device and method for high-silicon-content Si-Pc materials based on the batch process. Summary of the Invention

[0006] The purpose of the present invention is to provide a production device and method for high-silicon-content Si-Pc materials based on the batch process to solve the problems raised in the above background art.

[0023] On the other hand, the present invention also provides a production method of a high-silicon-content Si-Pc material based on the intermittent method, including the following steps:

[0024] S1. First, an operator feeds the raw materials for producing the high-silicon-content Si-Pc material into the interior of the lower reaction device through the feed hopper in the fixing device.

[0025] S2. Subsequently, start the drive motor in the drive device to drive the drive shaft to rotate. The outer sleeve cam and the pulley fixed on the outer side wall of the drive shaft rotate together with the drive shaft. Through the power transmission of the transmission belt, another pulley and another drive shaft are driven to rotate simultaneously.

[0026] S3. At this time, one outer sleeve ring in the conversion part is sleeved inside the outer sleeve ring gear to drive the outer sleeve ring gear to rotate, and then drive the shaft end gear located above and the transmission shaft to rotate together.

[0027] S4. The lower shaft end gear rotates with the transmission shaft, causing the inner sleeve ring gear and the transport circular plate to rotate. After the transport circular plate rotates 90°, the reaction device with the placed raw materials is moved below the drive device, and the drive motor is turned off.

[0028] S5. Then, control the electric push rod to drive the moving flat plate to move downward, so that the inner outer sleeve ring leaves the inside of the outer sleeve cam, and the outer outer sleeve ring is inserted into the inside of the rod end sleeve shaft of the lower reaction device.

[0029] S6. After that, start the drive motor again to drive the outer sleeve ring to rotate through another drive shaft, and then drive the rod end sleeve shaft and the stirring rod to rotate together to stir the materials in the reaction tank. During this process, the next batch of materials to be reacted is fed into the reaction device below the feed hopper.

[0030] S7. Subsequently, open the spherical valve in the reaction device, add the uniformly mixed materials into the twin-screw extruder, and melt and extrude them under high temperature and high pressure. During the extrusion process, by controlling parameters such as the temperature of each zone and the screw speed, the materials are fully mixed and extruded into strips.

[0031] S8. Then, quickly cool and shape the extruded strip materials to prevent them from deforming or degrading, and cut the cooled and shaped materials into uniform granular shapes to obtain the final high-silicon-content Si-PC material product.

[0032] S9. Again, through the conversion unit, switch the object of the power output of the drive motor, and change the fixed positions of the four reaction devices through the transportation unit. Subsequently, repeat the above operations to intermittently complete the production of the high-silicon-content Si-PC material product.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. For the production device and method of the high-silicon-content Si-Pc material based on the intermittent method, by changing the internal structural position of the conversion unit, the output direction of the power of the drive motor can be changed, enabling the positions of multiple groups of reaction devices to be alternately changed in sequence, and simultaneously performing the production processes of proportioning feeding, high-pressure reaction, rapid flushing, and static drying respectively, thereby improving the effective utilization rate of the overall equipment and ensuring the continuity of the final material production.

[0035] 2. For the production device and method of the high-silicon-content Si-Pc material based on the intermittent method, by rotating the outer sleeve cam in the driving device, the piston plate can be driven to move in the sealed housing, and pressure is applied to the liquid storage tank, thereby improving the automation of the overall equipment while reducing the investment in additional driving equipment.

[0053] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] Please refer to Figures 1 - 12 As shown, the present embodiment provides a technical solution:

[0055] Production device for Si-Pc material with high silicon content based on intermittent method, including a fixing device 100, a driving device 200 arranged at the center of the top of the fixing device 100, four reaction devices 300 distributed in a matrix inside the fixing device 100, and a pressurizing device 400 arranged on the top surface of the fixing device 100.

[0056] In this embodiment, as Figures 3 - 4 shown, the fixing device 100 includes a fixing frame 110, a spacer plate 130 arranged at a position near the top of the inner side wall of the fixing frame 110, and a transport part 150 arranged on the bottom surface inside the fixing frame 110.

[0057] Specifically, the transport part 150 includes a transmission shaft 151, shaft end gears 152 arranged at the upper and lower ends of the transmission shaft 151, and a transport circular plate 153 that rotates with the shaft end gears 152. Every time the transport circular plate 153 rotates 90°, the fixed positions of the four reaction devices 300 are alternately changed in sequence, so that different processes are carried out respectively inside the four reaction devices 300.

[0058] Furthermore, support frames 120 are welded on both sides of the bottom surface of the fixing frame 110. The spacer plate 130 is fixedly connected to the inner side wall of the fixing frame 110 by bolts. A feed hopper 140 with its bottom end extending below the spacer plate 130 is clamped at the circular hole on the top surface of the fixing frame 110. The upper and lower ends of the transmission shaft 151 are rotatably connected inside the fixing frame 110. The shaft end gears 152 are fixedly connected to the outer side wall of the transmission shaft 151 by pins. The transport circular plate 153 is rotatably connected to the bottom surface inside the fixing frame 110. An inner sleeve ring gear 154 meshing with the shaft end gears 152 is clamped on the inner ring wall of the inner circular groove of the transport circular plate 153. After the inner sleeve ring gear 154 rotates, it drives the transport circular plate 153 to rotate. Every time the transport circular plate 153 rotates 90°, the fixed positions of the four reaction devices 300 are alternately changed in sequence.

[0059] Furthermore, both the fixing frame 110 and the support frames 120 are used to ensure the overall strength of the fixing device 100. The spacer plate 130 is used to seal the top space of the reaction device 300 and provide a fixed platform for the driving device 200. The feed hopper 140 is used to facilitate the operator to feed raw materials into the reaction device 300.

[0060] Furthermore, after the upper shaft end gear 152 rotates, it drives the transmission shaft 151 to rotate. When the lower shaft end gear 152 abuts against the inner sleeve ring gear 154, it drives the whole transport circular plate 153 to rotate. Every time the transport circular plate 153 rotates 90°, the fixed positions of the four reaction devices 300 are alternated.

[0061] In this embodiment, as Figure 5As shown in the figure, the driving device 200 includes a driving motor 210, two driving shafts 220 that rotate with the output shaft of the driving motor 210, an outer sleeve cam 230 disposed above the driving motor 210, a conversion part 260 between the two driving shafts 220, and an outer sleeve ring gear 270 disposed below the outer sleeve cam 230.

[0062] Specifically, the driving motor 210 is fixedly connected to the bottom surface of the spacer plate 130 by bolts, the driving shaft 220 is rotatably connected to the top surface of the spacer plate 130, one of the driving shafts 220 is coaxially connected to the output shaft of the driving motor 210, and a number of regularly distributed limiting convex strips 221 are integrally formed on the outer side wall of the driving shaft 220. The outer sleeve cam 230 is fixedly connected to the outer side wall of the driving shaft 220 by a retaining pin.

[0063] Further, pulley wheels 240 are fixedly clamped at the tops of the two driving shafts 220, a transmission belt 250 is sleeved between the pair of pulley wheels 240. After the driving motor 210 drives one of the driving shafts 220 to rotate, the other driving shaft 220 is driven to move together through the pulley wheels 240 and the transmission belt 250.

[0064] Further, after the driving motor 210 is started, it drives the driving shaft 220 to rotate. The outer sleeve cam 230 and the pulley wheel 240 fixed on the outer side wall of the driving shaft 220 rotate together with the driving shaft 220. Through the power transmission of the transmission belt 250, the other pulley wheel 240 and the other driving shaft 220 are driven to rotate simultaneously.

[0065] In this embodiment, as Figures 6 - 8 shown, the conversion part 260 includes an electric push rod 261, a moving flat plate 262 that moves up and down with the telescopic rod of the electric push rod 261, and a pair of outer sleeve rings 263 symmetrically arranged at both ends of the moving flat plate 262.

[0066] Specifically, the electric push rod 261 is fixedly clamped to the inner top surface of the fixed frame 110, the moving flat plate 262 is fixedly clamped to the telescopic rod of the electric push rod 261, the outer sleeve ring 263 is rotatably connected to the inside of the moving flat plate 262. An inner slot 2630 adapted to the size of the driving shaft 220 is formed inside the outer sleeve ring 263. When the driving shaft 220 rotates, the outer sleeve ring 263 will rotate inside the moving flat plate 262, and a limiting ring 264 is integrally formed on the outer side wall of the outer sleeve ring 263.

[0067] Further, a number of regularly distributed placement grooves are formed on the inner side wall of the outer sleeve ring body 263. A limiting convex block 265 is slidably connected inside the outer sleeve ring body 263 at the placement groove. A number of regularly distributed first pressure springs 266 are welded on the inner side wall of the limiting convex block 265. The other ends of the first pressure springs 266 are welded on the inner groove wall of the placement groove. The elastic force provided by the first pressure springs 266 pushes the limiting convex block 265 to move outwards. The outer sleeve ring gear 270 is rotatably connected to the inner top surface of the fixed frame body 110. The outer sleeve ring gear 270 meshes with the shaft end gear 152 located above and a number of regularly distributed docking slots 271 adapted to the limiting convex block 265 are formed on the inner ring wall.

[0068] Further, the activation of the electric push rod 261 will drive the position of the moving flat plate 262 to move up and down, and respectively change the positions of the two outer sleeve ring bodies 263. The outer sleeve ring body 263 itself is sleeved on the outside of the drive shaft 220 through the inner slot 2630 and always rotates together with the drive shaft 220. The limiting ring body 264 is used to limit the rotation range of the outer sleeve ring body 263 on the moving flat plate 262.

[0069] Further, when the inner outer sleeve ring body 263 is inserted into the inside of the outer sleeve ring gear 270, the limiting convex block 265 will first be squeezed by the ring wall of the outer sleeve ring gear 270 and retract into the placement groove of the outer sleeve ring body 263. Subsequently, under the elastic force of the first pressure spring 266, it extends into the inside of the docking slot 271, and drives the whole outer sleeve ring gear 270 to rotate together with the outer sleeve ring body 263, thereby driving the shaft end gear 152 located above to rotate.

[0070] In this embodiment, as Figures 9 - 10 shown, the reaction device 300 includes a reaction tank body 310, a stirring rod 320 arranged inside the reaction tank body 310, and a rod end sleeve shaft 330 arranged at the top end of the stirring rod 320. When the electric push rod 261 drives the moving flat plate 262 to move up and down, a pair of outer sleeve ring bodies 263 are sequentially sleeved with the outer sleeve ring gear 270 and the rod end sleeve shaft 330 respectively to transmit rotational motion, so that the change in the position of the reaction device 300 and the rotation of the internal stirring rod 320 can be alternated, and thus the four reaction tank bodies 310 can intermittently complete the reaction of materials.

[0071] Specifically, the reaction tank body 310 is fixedly connected to the top surface of the transport circular plate 153 through bolts. A tank top opening 311 that penetrates up and down is formed on the top surface of the reaction tank body 310. The stirring rod 320 is rotatably connected inside the reaction tank body 310. The rod end sleeve shaft 330 is clamped and fixed at the top end of the stirring rod 320. An axial wall slot 331 adapted to the limiting convex block 265 is formed on the inner side wall of the rod end sleeve shaft 330. A spherical valve 340 is flange-connected to the discharge pipe at the bottom end of the reaction tank body 310.

[0072] Furthermore, the reaction tank body 310 is used to increase the reaction range of the material, and the tank top opening 311 is used to facilitate the input of the material. When the outer sleeve ring body 263 is inserted into the rod end sleeve shaft 330, and the limiting protrusion 265 extends to the shaft wall groove 331 under the elastic force of the first pressure spring 266, it will drive the rod end sleeve shaft 330 together with the stirring rod 320 to rotate, thereby stirring the raw materials inside.

[0073] In this embodiment, Figures 11 - 12 As shown, the pressurizing device 400 includes a sealing cover body 410, a piston plate 430 that reciprocates inside the sealing cover body 410 as the outer sleeve cam 230 rotates, and a liquid storage tank 460 for storing cleaning liquid. The movement of the piston plate 430 will introduce airflow into the interior of the liquid storage tank 460, thereby automatically pressurizing the interior of the liquid storage tank 460.

[0074] Specifically, the sealing cover body 410 is clamped and fixed on the top surface of the fixed frame body 110, and a plurality of ventilation holes are opened at one end of the sealing cover body 410 close to the outer sleeve cam 230. A sliding rod body 420 that is slidably connected to the outer sleeve wall of the sealing cover body 410 is clamped on the outer wall of the piston plate 430, and a docking strip body 440 that contacts the outer sleeve cam 230 is clamped on the end of the sliding rod body 420. A second pressure spring 450 is sleeved on the outer side of the sliding rod body 420, and the elastic force provided by the second pressure spring 450 is used to push the docking strip body 440 to move in the direction of the outer sleeve cam 230.

[0075] Furthermore, the liquid storage tank 460 is placed on the top surface of the fixed frame 110, and the outer walls of the liquid storage tank 460 are respectively clamped with a ventilation pipe and a liquid outlet pipe 470 connected to the sealing cover body 410, and the end of the liquid outlet pipe 470 is threadedly connected with an electric-controlled nozzle 480, which is clamped and fixed on the bottom surface of the partition plate 130.

[0076] Furthermore, as the drive shaft 220 rotates, the position of the outer cam 230 in contact with the docking strip body 440 is constantly changing, and the elastic force of the second pressure spring 450 always pushes the docking strip body 440 to move in the direction of the outer cam 230, and then drives the piston plate 430 to move continuously inside the sealing cover body 410 through the sliding rod body 420, allowing the air flow to flow into the sealing cover body 410 from the air inlet valve on the sealing cover body 410, and then be sent into the interior of the liquid storage tank 460 through the ventilation pipe. When the reaction device 300, after the reaction is completed and the discharge is completed, moves to the bottom of the electric control nozzle 480, the electric control nozzle 480 is opened to flush the inner wall of the reaction tank body 310.

[0077] The production method of the high silicon content Si-Pc material based on the intermittent process of the present invention comprises the following steps:

[0078] S1. First, the operator feeds the raw materials for producing the Si-Pc material with a high silicon content into the interior of the lower reaction device 300 from the feed hopper 140 in the fixing device 100;

[0079] S2. Subsequently, start the drive motor 210 in the drive device 200, which drives the drive shaft 220 to rotate. The outer sleeve cam 230 and the pulley 240 fixed on the outer side wall of the drive shaft 220 rotate together with the drive shaft 220. Through the power transmission of the transmission belt 250, another pulley 240 and another drive shaft 220 are driven to rotate simultaneously;

[0080] S3. At this time, an outer sleeve ring body 263 in the conversion part 260 is sleeved inside the outer sleeve ring gear 270, driving the outer sleeve ring gear 270 to rotate, and further driving the shaft end gear 152 located above and the transmission shaft 151 to rotate;

[0081] S4. The lower shaft end gear 152 rotates with the transmission shaft 151, causing the inner sleeve ring gear 154 and the transport circular plate 153 to rotate. After the transport circular plate 153 rotates 90°, the reaction device 300 with the raw materials placed is moved below the drive device 200, and the drive motor 210 is turned off;

[0082] S5. Then, control the electric push rod 261 to drive the moving flat plate 262 to move downward, causing the inner outer sleeve ring body 263 to leave the interior of the outer sleeve cam 230, and the outer outer sleeve ring body 263 to insert into the interior of the rod end sleeve shaft 330 in the lower reaction device 300;

[0083] S6. After that, start the drive motor 210 again, driving the outer sleeve ring body 263 to rotate through another drive shaft 220, and further driving the rod end sleeve shaft 330 and the stirring rod 320 to rotate, thereby stirring the materials in the reaction tank body 310.
