Description

Technical Field

[0001] The invention belongs to the technical field of polymerization reaction equipment, and in particular relates to a reaction kettle based on polyphenylene sulfide particle processing. Background Art

[0002] Polyphenylene sulfide is a high-performance thermoplastic resin with many excellent properties. Its molecular structure is mainly composed of alternating benzene rings and sulfur atoms, which makes PPS have high rigidity and good flexibility. There are many methods for synthesizing PPS, including one-step method and two-step method.

[0003] In the Chinese utility model patent with publication number CN206810264U, it is mentioned that the utility model can well control the temperature in the kettle through the stirring device and the temperature regulating device, so that the temperature in the kettle can be uniform and constant, and the temperature of the reactor can be effectively controlled, so that the reaction rate of the reaction monomers is consistent and the polymerization degree is uniform;

[0004] In actual use, when polyphenylene sulfide is prepared by the sodium sulfide method, it mainly goes through a heating stage, a transition stage and a polymerization stage. In the heating stage, the reactants need to be heated by a reactor to quickly reach the reaction temperature. When the transition stage is reached, the reactants need to be cooled. In the polymerization stage, the reactants continue to release heat, and timely heat dissipation is required to avoid violent reactions. This requires timely control of the temperature of the reactants and the polymer during the reaction to ensure the controllability of the reaction. Among them, the reactants in the heating stage are in a solution state, and stirring can achieve a mixing effect. However, in the polymerization stage, due to the production of solid polymers, they are easy to become viscous. The material flow rate is reduced during stirring, and the reactants at the bottom are not fully mixed due to the aggregation of the polymers. The reactants and polymers are easily accumulated in dead corners such as the bottom outlet of the reactor, resulting in incomplete utilization of the reactants. In view of this, a reactor based on polyphenylene sulfide particle processing is provided. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] like Figure 1-Figure 10As shown, this embodiment provides a reactor based on polyphenylene sulfide particle processing, including a stainless steel tank 2 and a driving member 3. The stainless steel tank 2 is used as a container for polymerization reaction. In order to prevent corrosion, stainless steel is mostly used. The driving member 3 is used as a power source. A motor is arranged on the top for rotational drive. The motor is located on the outside of the stainless steel tank 2 to avoid occupying the internal space of the stainless steel tank 2. The stainless steel tank 2 is equipped with a stirring member. When the polymerization reaction is carried out, the driving member 3 drives the stirring member to rotate, and the reactants are turned over and mixed by the stirring member. The stainless steel tank 2 also includes an interlayer 22. Flanges are installed at both ends of the top and bottom of the interlayer 22. The flanges are connected to the external cold source and heat source through pipelines. In the initial stage of the reaction, the heat source fills the interlayer 22 with a circulating high-temperature medium through the flange to heat the inside of the stainless steel tank 2. Temperature, so that the temperature quickly reaches the reaction temperature. When the polymerization reaction starts and continuously releases heat, the cold source fills the circulating low-temperature medium into the interlayer 22 through the flange, absorbs heat and cools the inside of the stainless steel tank 2, controls the internal temperature of the stainless steel tank 2 during the polymerization reaction, and uses the inner wall of the stainless steel tank 2 for direct contact heating and cooling. In addition, the temperature control is performed in a staggered manner instead of the heating equipment and the cooling equipment to ensure a large contact area. When heating, there is no cold source. Similarly, when cooling, there is no need to cool the heat source simultaneously, and the heat exchange efficiency is higher. The outer side of the interlayer 22 is installed with an interlayer 23, and the interlayer 23 is hollowed out or filled with a heat-insulating medium to prevent the external temperature from affecting the internal temperature of the stainless steel tank 2 and to prevent the temperature fluctuation in the stainless steel tank 2 from being too large and affecting the temperature control.

[0036] Different polymerization stages have different requirements for stirring and tumbling. In the early stage of polymerization, the reactants need to absorb heat and quickly reach the reaction temperature. In the transition period, the polymerization reaction gradually begins to release heat. It is necessary to fully stir and mix the viscous polymer and dissipate heat. Therefore, the structure of the stirring element needs to be optimized. Specifically, a configuration of a stirring element is provided. Figure 2 The stirring member includes a horizontal frame 4, a vertical frame 5 and a bottom frame 6.

[0037] For horizontal frame 4, refer to Figure 2 The cross frame 4 is provided with a collar and two fins which are mirror-symmetrically installed on the circumferential side walls of the collar, wherein the fins extend obliquely from top to bottom in the direction of rotation of the driving member 3. When the driving member 3 rotates, the cross frame 4 will push the material in the middle of the stainless steel tank 2 downward. There are two cross frames 4, which are equidistantly installed in the middle of the driving member 3. To cope with the deeper space of the stainless steel tank 2, the internal material can be pushed in sections, and the material in the middle can be pushed downward in relay. The two cross frames 4 are arranged at an angle of ninety degrees. This staggered angle design can stagger the fins of the upper and lower cross frames 4. When the upper fins push the material downward, the lower fins will not overlap with the downward path of the material, thereby avoiding the obstruction of the lower fins causing the material to go down unsmoothly, thereby improving the pushing efficiency.

[0038] For vertical frame 5, refer to Figure 3-Figure 7 The vertical frame 5 includes a relay sleeve 57, which has an annular main body with a vertical axis. The relay sleeve 57 is installed at the bottom end of the driving member 3, and is locked by bolts after being connected from bottom to top. The relay sleeve 57 has a mounting opening horizontally provided in the middle of the main body, and a horizontal vertical portion 51 is horizontally inserted and installed in the middle of the relay sleeve 57. After the horizontal vertical portion 51 is inserted into the mounting opening, a vertical portion 53 is provided at one end of the horizontal vertical portion 51 close to the vertical inner wall of the stainless steel tank 2;

[0039] At the beginning of the reaction, the driving member 3 rotates at a low speed, and the horizontal part 51 can push the materials in the lower middle layer toward the vertical inner wall of the stainless steel tank 2, and the top of the vertical part 53 is inclined away from the rotation direction of the driving member 3, and its inclined end surface can push part of the materials on the inner edge of the stainless steel tank 2 upward, and return to the middle to replenish the position of the horizontal frame 4, while the materials in the lower middle layer will be dispersed around to replenish the lower part of the vertical part 53. At this time, the materials in the middle are cyclically pushed to the vertical inner wall of the stainless steel tank 2 for efficient contact heating;

[0040] During the transition period and reaction period of polymerization, the polymerization reaction produces solids that make the solution viscous. The driving member 3 rotates at high speed to turn over the viscous material. The horizontal portion 51 is limited by a movable connection. Under the action of centrifugal force, the horizontal portion 51 can slide horizontally in the relay sleeve 57, and the vertical portion 53 will be closer to the vertical inner wall of the stainless steel tank 2. The extended vertical portion 53 rotates at the same angular velocity as the driving member 3. The larger the rotation radius of the vertical portion 53, the greater the rotation speed, which improves the stirring and mixing effect. At the same time, The vertical portion 53 is close to the vertical inner wall of the stainless steel tank 2 to stir the material, and a large flow rate is generated at the vertical inner wall of the stainless steel tank 2 for flushing, so as to flush down the solid polymer product adhering to the vertical inner wall of the stainless steel tank 2, and at the same time, it does not directly rub the vertical inner wall of the stainless steel tank 2, and prevents the vertical inner wall of the stainless steel tank 2 from being blocked by the polymer, thereby preventing poor heat conduction. Among them, a wedge block 56 is installed at one end of the horizontal portion 51 located on the inner side of the relay sleeve 57, and the wedge block 56 plays a limiting role to prevent the horizontal portion 51 from falling off from the relay sleeve 57 during high-speed rotation.

[0041] For chassis 6, refer to Figure 3-Figure 8 The base frame 6 includes a connecting rod 61, which is coaxially arranged vertically with the driving member 3, and the connecting rod 61 rotates synchronously with the driving member 3. A spring member 65 is installed between the connecting rod 61 and the driving member 3. The spring member 65 pulls the connecting rod 61 up and plugs it into the driving member 3. The connecting rod 61 is located at the outlet of the stainless steel tank 2 and a spiral plate 63 is installed;

[0042] When stirring at low speed, refer to Figure 3 and Figure 7In the polymerization reaction of preparing polyphenylene sulfide by the sodium sulfide method, at the initial stage of the reaction, the reactants are in a solution state. When the material pushed down by the horizontal frame 4 contacts the top surface of the spiral plate 63, it will be thrown around by the horizontal centrifugal force generated by the rotating spiral plate 63, so that the material in the lower layer can smoothly flow to the vertical part 53, so as to contact with the vertical inner wall of the stainless steel tank 2 to heat up, and be pushed by the inclined end surface of the vertical part 53 to circulate. Figure 4 At the initial stage of the reaction, the driving member 3 is in a low-speed state, and a convex edge 62 is installed at one end of the connecting rod 61 close to the wedge block 56. The wedge block 56 on the bottom surface of the horizontal portion 51 overlaps the inclined surface of the convex edge 62. The centrifugal force on the vertical frame 5 is small. The force of the wedge block 56 squeezing the convex edge 62 to push the connecting rod 61 downward cannot overcome the elastic potential energy of the spring member 65 pulling up. At this time, the top of the convex edge 62 will be at the top position of the wedge block 56, squeezing and gathering the two vertical portions 53 relatively away from the vertical inner wall of the stainless steel tank 2. At this time, the vertical portion 53 and the spiral plate 63 are arranged close to the horizontal frame 4 so as to contact the material pushed downward by the horizontal frame 4 and quickly stir and mix the solution;

[0043] Reference Figure 6 and Figure 8 During the transition period and the polymerization reaction period, the reactants are in a viscous state, the driving member 3 is in a high-speed state, the vertical frame 5 is subjected to a large centrifugal force, the wedge 56 overcomes the elastic potential energy of the spring member 65 to push the convex edge 62 downward, and the vertical portion 53 smoothly approaches the vertical inner wall of the stainless steel tank 2. Figure 5 A valve body is installed at the bottom of the outlet channel at the bottom of the stainless steel tank 2 for sealing and opening, and during the reaction, a blind hole with an opening upward is formed at the bottom of the stainless steel tank 2. The polymerization reaction products will gather in this dead corner and easily stick to each other, resulting in outlet blockage. At this time, the downward movement of the convex edge 62 will cause the spiral plate 63 to move downward through the connecting rod 61, and the lower part of the spiral plate 63 can be inserted into the bottom outlet of the stainless steel tank 2. As it rotates, the material gathered in the bottom outlet of the stainless steel tank 2 can be pushed up, so that the solution here can move upward to participate in the mixing and fully react. At the same time, it prevents the solid polymers from sticking to each other here and causing outlet blockage, thereby ensuring smooth subsequent discharge.

[0044] In a further embodiment, in order to ensure that the material can still be smoothly pushed to contact the vertical inner wall of the stainless steel tank 2 after the polymerization reaction becomes viscous, refer to Figure 7 and Fig. 9A straight plate 64 is installed in the middle of the circumferential side wall of the connecting rod 61, and there are multiple straight plates 64. At the same time, the straight plates 64 are vertically fixed along the axis of the connecting rod 61, and can rotate synchronously when the connecting rod 61 rotates to generate horizontal centrifugal force. The straight plates 64 are installed in a circular array, which can generate uniform centrifugal driving force to push the material in the middle to the surrounding more quickly. In addition, the outer diameter of the upper half of the spiral plate 63 is greater than the length of the straight plate 64. The spiral plate 63 can fully block the descending material from above, preventing the material from directly entering the bottom outlet of the stainless steel tank 2, and the rotation of the spiral plate 63 and the shielding of the top surface of the spiral plate 63 can ensure that the material flows smoothly to the surroundings.

[0045] In a further embodiment, the spiral plate 63 can rotate to lift the material in the bottom outlet of the stainless steel tank 2. Figure 5 and Figure 7 The stainless steel tank 2 includes a bottom tube 24, which is installed at the bottom outlet of the stainless steel tank 2. The inner wall of the bottom tube 24 is smoothed to avoid adhesion of the polymer. The bottom end of the bottom tube 24 provides an installation space for the valve body. At the same time, the spiral direction of the spiral plate 63 from top to bottom is consistent with the rotation direction of the driving member 3. When the driving member 3 rotates at a high speed, the outer diameter of the lower half of the spiral plate 63 is equal to the inner diameter of the bottom tube 24. The lower half of the spiral plate 63 is inserted into the bottom tube 24 and slides in contact with the inner wall of the bottom tube 24, so that the material can be smoothly pushed up and out of the bottom tube 24, eliminating the reaction dead angle of the equipment. At the same time, the outer diameter of the upper half of the spiral plate 63 is larger than the inner diameter of the bottom tube 24, which can generate a larger upward thrust, so that the material raised in the bottom tube 24 can be smoothly pushed up and mixed with the material above for sufficient reaction.

[0046] In a further embodiment, in order to ensure that the material in the middle of the viscous state can contact the inner wall of the stainless steel tank 2 for cooling, refer to Figure 7 A bending portion 52 is provided at the connection between the horizontal portion 51 and the vertical portion 53, wherein the bending portion 52 first extends downward and then bends upward. The horizontal portion 51, the vertical portion 53 and the bending portion 52 are all designed vertically along the axis of the connecting rod 61. The bending portion 52 has a large vertical surface area. The horizontal portion 51 and the bending portion 52 can contact with more materials when rotating, and use centrifugal force to push and stir the materials in the middle more efficiently. At the same time, the horizontal portion 51, the vertical portion 53 and the bending portion 52 are formed as one piece to ensure the structural strength of the structure.

[0047] In a further embodiment, in order to ensure smooth contact between the material and the vertical inner wall of the stainless steel tank 2, refer to Figure 7, an oblique bar 55 is provided at one end of the vertical portion 53 away from the vertical inner wall of the stainless steel tank 2, and at the same time, the oblique bar 55 extends obliquely in the rotation direction of the vertical portion 53. When the vertical portion 53 rotates at a low speed, the oblique bar 55 will squeeze and push the contacted material toward the vertical inner wall of the stainless steel tank 2, so that more material can quickly flow to the vertical inner wall of the stainless steel tank 2 for high-speed contact heating; when the vertical portion 53 rotates at a high speed, the oblique bar 55 makes the flow rate of the material flushing the vertical inner wall of the stainless steel tank 2 greater, ensuring that the adhered polymer can be smoothly The vertical portion 53 is provided with a convex strip 54 at one end close to the vertical inner wall of the stainless steel tank 2, and the convex strip 54 is located on the side of the vertical portion 53 that is not facing the rotation direction. When stirring, the convex strip 54 can improve the structural strength of the vertical side wall of the vertical portion 53, and the convex strip 54 is arranged close to the vertical inner wall of the stainless steel tank 2. When the vertical portion 53 rotates at a high speed, the material passes through the narrow gap between the convex strip 54 and the vertical inner wall of the stainless steel tank 2, which can further improve the material flow rate here and perform efficient flushing and cleaning.

[0048] In a further embodiment, in order to realize the sliding and limiting of the horizontal straight portion 51, a specific configuration is provided, referring to Figure 8 and Fig.10 The bottom surface of the horizontal straight portion 51 near the wedge block 56 is provided with a notch that cooperates with the convex edge 62, and the middle part of the connecting rod 61 is provided with a slot 66 that cooperates with the wedge block 56. In the low-speed rotation state, the convex edge 62 is inserted into the notch, and the wedge block 56 is inserted into the bottom of the slot 66. At this time, the two horizontal straight portions 51 are gathered in the relay sleeve 57. In the high-speed rotation state, the middle part of the bottom end of the relay sleeve 57 is provided with a square hole that cooperates with the wedge block 56. The wedge block 56 slides horizontally at the position of the square hole. The wedge block 56 squeezes the convex edge 62 to push the connecting rod 61 downward. At the same time, the relay sleeve 57 is vertically slidably connected to the connecting rod 61 via the slot 66, and the connecting rod 61 slides on the outside of the relay sleeve 57. When the connecting rod 61 descends to the lower dead point, the top surface of the relay sleeve 57 will contact the top surface of the slot 66, so that the connecting rod 61 is vertically guided and limited by the relay sleeve 57.

[0049] In a further embodiment, a specific configuration is provided for horizontally sliding the vertical portion 51, referring to Figure 8The middle part of the relay sleeve 57 is provided with a horizontally penetrating installation opening, wherein the horizontal straight part 51 is horizontally inserted into the installation opening, and the two horizontal straight parts 51 are symmetrically arranged one on the left and the other on the right. At the same time, the relay sleeve 57 is provided with a limit pin 58 at the opening of the installation opening. The limit pin 58 penetrates the vertical side wall of the relay sleeve 57 from front to back and is fixed at the end by a nut, which can be disassembled and replaced. A horizontally extending sliding hole 59 is opened in the middle part of the horizontal straight part 51. The left and right widths of the sliding hole 59 are greater than the outer diameter of the limit pin 58. At the same time, the left and right widths of the sliding hole 59 are equal to the horizontal sliding distance of the wedge block 56. Therefore, the left and right widths of the sliding hole 59 need to ensure that the wedge block 56 will not cross the top of the convex edge 62 and separate from the base frame 6 when sliding, so as to ensure stable contact. The limit pin 58 penetrates the horizontal straight part 51 through the sliding hole 59, and the horizontal outer wall of the horizontal straight part 51 slides horizontally with the inner wall of the relay sleeve 57, and cooperates with the limit of the limit pin 58 to ensure that the horizontal straight part 51 can slide horizontally stably, thereby improving the sliding distance accuracy and stability of the horizontal straight part 51.

[0050] In a further embodiment, a specific configuration of the driving member 3 is disclosed, referring to Figure 7 The driving member 3 includes a central axis 31, which extends downward to the middle of the stainless steel tank 2. A slide groove 32 is provided at the bottom end of the central axis 31. The slide groove 32 opens downward. The vertical outer wall of the connecting rod 61 is slidably plugged with the vertical inner wall of the slide groove 32. The outer wall of the connecting rod 61 is provided with a vertical convex rib, and the inner wall contour of the slide groove 32 is consistent with the vertical convex rib. The connecting rod 61 is slidably plugged with the bottom end of the central axis 31 through the slide groove 32, which can ensure that the connecting rod 61 is axially slidably connected with the central axis 31 through the slide groove 32. Even if the connecting rod 61 slides up and down, when the central axis 31 rotates, the connecting rod 61 can also be driven to rotate synchronously. Among them, the top end of the spring member 65 is fixedly connected to the inner wall of the top end of the slide groove 32. The spring member 65 is installed in the slide groove 32, and the connecting rod 61 is lifted up by elastic force, and is sealed in the slide groove 32 by the connecting rod 61 to prevent the solid polymer generated during the reaction from adhering to the outer wall of the spring member 65 and affecting the normal expansion and contraction deformation of the spring member 65.

[0051] In a further embodiment, referring to Figure 1 and Figure 2 The stainless steel tank 2 includes a tank body 21, which opens upward. A cylindrical cavity is formed inside the tank body 21 for accommodating reactants and providing polymerization space, wherein a sealing cover is installed on the top of the tank body 21, and the sealing cover is installed at the top opening position of the tank body 21 by bolts. The sealing cover has multiple joints for inputting materials and installing monitoring instruments. A sealing bearing is installed between the middle of the sealing cover and the driving member 3, and is rotationally sealed with the central axis 31. At the same time, a base 1 is installed on the outer wall of the tank body 21, and the tank body 21 can be supported overhead, so as to facilitate the connection of the discharge pipe and the discharge pump at the bottom.

[0052] The working principle of this embodiment is as follows:

[0053] In the early stage of polymerization, the reactants need to absorb heat and quickly reach the reaction temperature. The outer wall of the stainless steel tank 2 is provided with an interlayer 22. The heat source is used to fill the interlayer 22 with a circulating high-temperature medium through the flange to heat the vertical inner wall of the stainless steel tank 2. The reactants enter the stainless steel tank 2, and the horizontal frame 4 of the stirring member pushes the reactants in the middle downward. The downward reactants contact the horizontal part 51 of the vertical frame 5 and the spiral plate 63 of the bottom frame 6, and are pushed and dispersed to the surroundings by the centrifugal force of the horizontal part 51 and the spiral plate 63. They contact and absorb heat from the circumferential inner wall of the stainless steel tank 2. The horizontally scattered reactants impact the circumferential inner wall of the stainless steel tank 2 and turn upward. The vertical frame 5 rotates to assist the reactants in pushing upward through the vertical part 53, so that the reactants in the middle are circulated and pushed to the vertical inner wall of the stainless steel tank 2 to absorb heat, so that the temperature of the reactants quickly reaches the reaction temperature.

[0054] During the polymerization reaction stage, the reactants produce solid polymers and continuously release heat. The cold source is a circulating low-temperature medium filled into the interlayer 22 through the flange to cool the inside of the stainless steel tank 2 and control the internal temperature of the stainless steel tank 2 during the polymerization reaction. The driving member 3 rotates at a high speed, and the vertical frame 5 extends horizontally through the centrifugal force to overcome the pressure of the spring member 65, and a higher speed of stirring and mixing will be performed. The vertical portion 53 will be closer to the vertical inner wall of the stainless steel tank 2. The vertical portion 53 has an inclined bar 55 to allow the material to flow toward the vertical inner wall of the stainless steel tank 2 for flushing, and the solid polymer product adhered to the vertical inner wall of the stainless steel tank 2 will be flushed down. Because the horizontal lateral movement of the vertical frame 5 will push the bottom frame 6 to move down, at this time, the lower part of the spiral plate 63 is inserted into the bottom outlet of the stainless steel tank 2, and the material gathered in the blind hole at the bottom of the stainless steel tank 2 can be pushed up with the rotation, so that the solution here can go up to participate in the mixing and fully react. At the same time, it prevents the solid polymers from sticking to each other here and causing the outlet to be blocked, thereby ensuring smooth subsequent discharge.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
