Abstract
Description
Technical Field
[0001] This utility model relates to the field of polypropylene catalyst production technology, specifically a polypropylene catalyst production device with mixing function. Background Technology
[0002] Polypropylene is produced by the addition polymerization of propylene. To accelerate the polymerization rate of polypropylene, a certain amount of catalyst can be added during the polypropylene production process to reduce the polymerization time. Polypropylene catalyst is a type of chemical substance that can accelerate or control the polymerization reaction of propylene monomers during the polypropylene production process, converting them into polypropylene polymer compounds. Polypropylene catalyst can be generated by the reaction of various materials and needs to be carried by a sealed device during the production process.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN216260798U) discloses a polypropylene catalyst production device with a stirring function. The device includes: a motor fixed to the upper right side of a moving plate; return springs for moving the moving plate left and right are fixed through the right shaft of the motor and the left shaft of the production tank; a sector gear, bearing-connected to the front side of the production tank; and an upper connecting pipe for allowing the cleaning liquid to flow, fixed to the upper left corner of the production tank. This polypropylene catalyst production device with a stirring function is equipped with a stirring rod and a sector gear. Through the stirring of the stirring rod, the sector gear causes the production tank to move while rotating, ensuring uniform mixing of the internal materials, accelerating production speed, improving work efficiency, avoiding incomplete reactions, and improving catalyst performance.
[0004] While the aforementioned patent utilizes structures such as stirring rods and sector gears—where the stirring rod agitates the material and the sector gears move the production tank while it rotates—to ensure uniform mixing, accelerate production, improve efficiency, and prevent incomplete reactions, thereby enhancing catalyst performance, the production process of polypropylene catalysts requires the catalyst to be pulverized. This necessitates further grinding of the polypropylene catalyst after stirring, mixing, and solidification. This requires manual movement of the catalyst and grinding using an external grinder, making polypropylene catalyst production inconvenient and reducing production efficiency.
[0005] Therefore, this invention provides a polypropylene catalyst production apparatus with mixing function to solve the above problems. Summary of the Invention
[0006] (a) Technical problems to be solved
[0007] This invention provides a polypropylene catalyst production apparatus with mixing function, which aims to solve the problems mentioned in the background art.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, the present invention provides the following technical solution: a polypropylene catalyst production device with mixing function, comprising a reaction vessel, wherein a stirring mechanism is installed inside the reaction vessel, and a heating and grinding mechanism is installed in the middle of the reaction vessel;
[0010] The heating and grinding mechanism includes two heat insulation plates rotatably connected to the reaction vessel. The two heat insulation plates are rotatably connected by hinges. A rotating plate is attached to the upper surface of the heat insulation plate. A rotating rod is fixedly connected to the surface of each of the two rotating plates. A first bevel gear is fixedly connected to one end of the rotating rod. A second bevel gear is meshed with the surfaces of the two first bevel gears. A fixed rod fixedly connected to the reaction vessel is fixedly connected to one end of the second bevel gear. A drive motor is fixedly connected to one end of one of the rotating rods through the reaction vessel.
[0011] As a preferred technical solution of this application, the heating and grinding mechanism further includes an electric heating plate fixedly connected inside the reactor, the electric heating plate corresponding to the heat insulation plate, a servo motor fixedly connected inside the reactor, a drive rod fixedly connected to the output end of the servo motor, and grinding rollers rotatably sleeved on both sides of the surface of the drive rod.
[0012] As a preferred technical solution of this application, the heating and grinding mechanism further includes a linkage gear fixedly connected to one end of the grinding roller. The grinding roller is rotatably connected to the inner bottom wall of the reactor. The surfaces of the two linkage gears are meshed with a toothed ring, which is fixedly connected to the inner wall of the reactor.
[0013] As a preferred technical solution of this application, the stirring mechanism includes a DC motor fixedly connected to the upper surface of the reactor, and a stirring rod rotatably connected to the output end of the DC motor, the stirring rod being in contact with the inner wall of the reactor.
[0014] As a preferred technical solution of this application, the inner bottom wall of the reactor is provided with a receiving groove, an elastic plate is fixedly connected inside the receiving groove, a sealing plate is fixedly connected to one end of the elastic plate, the sealing plate is rotatably connected inside the receiving groove, and the sealing plate seals the lower surface of the reactor.
[0015] As a preferred technical solution of this application, a push rod is fixedly connected to the lower surface of the sealing plate, support legs are fixedly connected to the surface of the reactor in a ring array, and a feed pipe corresponding to the stirring rod is fixedly connected to one side of the upper surface of the reactor.
[0016] (III) Beneficial Effects
[0017] By setting up a heating and grinding mechanism, inorganic salts dissolved in an organic solution are used as precursors. The precursors are fed into the reactor through a feed pipe, and distilled water is added to the reactor to hydrolyze the precursors, forming a sol. The sols then undergo condensation and aging to form a gel. The gel is dried and calcined by an electric heating plate. A servo motor is started, causing the grinding roller to rotate in the reactor. Simultaneously, a linkage gear rotates on the surface of the gear ring, causing the grinding roller to rotate itself. This process pulverizes the gel into powder, yielding a polypropylene catalyst. This method not only improves the dispersibility and controllability of the polypropylene catalyst, thereby enhancing its catalytic activity and stability and performance, but also allows for direct grinding of the polypropylene catalyst, reducing working steps and improving production efficiency.
[0018] By incorporating a stirring mechanism and other structural elements, after the precursor and distilled water are added to the reactor, a DC motor is started to rotate the stirring rod, which stirs the mixture of precursor and distilled water, making the mixture more uniform. Furthermore, the push rod pushes the sealing plate to rotate inside the receiving tank, thus removing the seal from the reactor and allowing the ground polypropylene catalyst to be discharged from the reactor, resulting in the final polypropylene catalyst. This makes unloading the polypropylene catalyst more convenient. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This invention provides a polypropylene catalyst production apparatus with mixing function, such as... Figures 1-5 As shown, the polypropylene catalyst production device with mixing function includes a reactor 1. A stirring mechanism is installed inside the reactor 1. Support legs are fixedly connected in a ring array on the surface of the reactor 1. Inorganic salt dissolved in an organic solution is used as a precursor. The precursor and distilled water are fed into the reactor 1 through a feed pipe. A feed pipe corresponding to the stirring rod 15 is fixedly connected to one side of the upper surface of the reactor 1. The stirring mechanism includes a DC motor 14 fixedly connected to the upper surface of the reactor 1. The output end of the DC motor 14 is fixedly connected to a stirring rod 15 rotatably connected inside the reactor 1. The stirring rod 15 is in contact with the inner wall of the reactor 1. When the DC motor 14 is started, its output end drives the stirring rod 15 to rotate, thereby stirring the mixture of precursor and distilled water, making the mixture more uniform.
[0028] A heating and grinding mechanism is installed in the middle of the reactor 1. The heating and grinding mechanism includes two heat insulation plates 2 rotatably connected in the reactor 1. By setting the heat insulation plates 2, the mixture is prevented from falling directly into the grinding roller 11, so that the mixture forms a sol in the upper part of the reactor 1.
[0029] Two heat insulation plates 2 are rotatably connected by hinges. A rotating plate 3 is attached to the upper surface of the heat insulation plate 2. The rotating plate 3 and the heat insulation plate 2 are magnetically attracted. Rotating rods 4 are fixedly connected to the surfaces of the two rotating plates 3. A first bevel gear 5 is fixedly connected to one end of the rotating rod 4. A second bevel gear 6 meshes with the surfaces of the two first bevel gears 5. A fixed rod fixedly connected to the reactor 1 is fixedly connected to one end of the second bevel gear 6. A drive motor 7 is fixedly connected to one end of one of the rotating rods 4 through the reactor 1. When the drive motor 7 is started, its output end drives the corresponding rotating rod 4 to rotate. Thus, through the cooperation of the first bevel gear 5 and the second bevel gear 6, the two rotating rods 4 rotate in opposite directions, driving the rotating plate 3 to rotate. This causes the two heat insulation plates 2 to rotate in opposite directions in the reactor 1, causing the sol to fall to the bottom of the reactor 1.
[0030] The heating and grinding mechanism also includes an electric heating plate 8 fixedly connected inside the reactor 1. The electric heating plate 8 corresponds to the heat insulation plate 2. When the servo motor 9 is started, the drive rod 10 rotates in the opposite direction, thereby resetting the heat insulation plate 2. The electric heating plate 8 is started to heat and dry the sol, so that the sol becomes a gel. The gel is then calcined by the electric heating plate 8, so that the gel becomes a solid.
[0031] A servo motor 9 is fixedly connected inside the reactor 1. A drive rod 10 is fixedly connected to the output end of the servo motor 9. Grinding rollers 11 are rotatably sleeved on both sides of the surface of the drive rod 10. The heating and grinding mechanism also includes a linkage gear 12 fixedly connected to one end of the grinding roller 11. The grinding roller 11 is rotatably connected to the inner bottom wall of the reactor 1. The surfaces of the two linkage gears 12 are meshed with a toothed ring 13. The toothed ring 13 is fixedly connected to the inner wall of the reactor 1. When the servo motor 9 is started, its output end drives the drive rod 10 to rotate, thereby causing the grinding roller 11 to rotate on the inner bottom wall of the reactor 1. At the same time, the linkage gear 12 rotates accordingly. Through the meshing of the toothed ring 13 and the linkage gear 12, the linkage gear 12 drives the grinding roller 11 to rotate, thus grinding the gel.
[0032] The inner bottom wall of the reactor 1 is provided with a receiving groove 16. An elastic plate 17 is fixedly connected inside the receiving groove 16. A sealing plate 18 is fixedly connected to one end of the elastic plate 17. The setting of the elastic plate 17 allows the sealing plate 18 to automatically reset, making the sealing plate 18 more convenient to use. A push rod 19 is fixedly connected to the lower surface of the sealing plate 18. The push rod 19 drives the sealing plate 18 to rotate inside the receiving groove 16, so that the sealing plate 18 no longer seals the reactor 1, allowing the polypropylene catalyst powder to be discharged from the reactor 1. The sealing plate 18 is rotatably connected to the inside of the receiving groove 16, and the sealing plate 18 seals the lower surface of the reactor 1.
[0033] Specifically, when this polypropylene catalyst production device with mixing function is in use: inorganic salt dissolved in organic solution is used as a precursor, and the precursor and distilled water are fed into the reactor 1 through the feed pipe. The DC motor 14 is started, and its output end drives the stirring rod 15 to rotate, thereby stirring the mixture of precursor and distilled water, making the mixture more uniform. The heat insulation plate 2 is set to prevent the mixture from falling directly into the grinding roller 11, so that the mixture forms a sol at the top inside the reactor 1. The drive motor 7 is started, and its output end drives the corresponding rotating rod 4 to rotate. The first bevel gear 5 and the second bevel gear 6 cooperate with each other, so that the two rotating rods 4 rotate in opposite directions, driving the rotating plate 3 to rotate. Thus, the two heat insulation plates 2 rotate in opposite directions in the reactor 1, so that the sol falls into the bottom of the reactor 1.
[0034] The servo motor 9 is started, causing the drive rod 10 to rotate in the opposite direction, thereby resetting the heat insulation plate 2. The electric heating plate 8 is then started to heat and dry the sol, turning it into a gel. The gel is then calcined by the electric heating plate 8, turning it into a solid. The servo motor 9 is started again, causing its output end to drive the drive rod 10 to rotate, thereby causing the grinding roller 11 to rotate on the inner bottom wall of the reactor 1. At the same time, the linkage gear 12 rotates accordingly. Through the meshing of the gear ring 13 and the linkage gear 12, the linkage gear 12 drives the grinding roller 11 to rotate, grinding the gel. Finally, the push rod 19 drives the sealing plate 18 to rotate inside the receiving tank 16, so that the sealing plate 18 no longer seals the reactor 1, allowing the polypropylene catalyst powder to be discharged from the reactor 1.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
