Description

Technical Field

[0001] This utility model relates to the field of high-pressure surfactant technology, specifically a stirring device with temperature control and surface microstructure viscosity reduction functions. Background Technology

[0002] High-pressure surfactant reactors often require prolonged, high-concentration stirring and mixing of raw materials. High-pressure surfactants have high viscosity, poor flowability, and are prone to film formation and adhesion to the reactor walls. Therefore, the reactor interior is typically equipped with scrapers for cleaning the vessel walls. The stirring blades and scrapers are mostly made of metal or engineering plastics, with simple polishing treatments. However, after long-term use, surface scratches or residues can easily appear. During the reaction, once surfactants adhere to the surface of the stirring blades or scrapers, it not only affects the quality of subsequent batches of material but also leads to a decrease in shear force during stirring, impacting the overall reaction progress and effectiveness.

[0003] Therefore, there is an urgent need for a stirring device with temperature control and surface microstructure de-sticking functions to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a stirring device with temperature control and surface microstructure anti-sticking functions, so as to solve the problem mentioned in the background art that the stirring blades and scrapers are mostly made of metal or engineering plastics, and surfactants are easy to stick and difficult to clean.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stirring device with temperature control and surface microstructure anti-sticking functions, comprising a reaction vessel, with discharge ports on both sides of the bottom end of the reaction vessel, a rotating seat fixed at the bottom of the reaction vessel, a stirring frame rotatably connected to the rotating seat, a plug at the top of the controller, a second gear fixedly sleeved below the plug, a cylinder fixed at the top of the inside of the reaction vessel, a piston rod installed at the output end of the cylinder, a connecting seat fixed at the bottom of the piston rod, a connecting rod fixedly connected to the right side of the connecting seat, a scraper fixedly connected to the right side of the connecting rod, the stirring blades and scraper of the stirring frame being coated with a microstructure coating, the microstructure coating being a fluorine-modified polymer microstructure material, a sleeve welded to the bottom of the connecting seat, the sleeve being matched with the plug, a drive motor fixedly connected to the left side of the top of the reaction vessel, the output shaft of the drive motor being connected to a gear reducer, the output shaft of the gear reducer extending into the reaction vessel and fixedly connected to a rotating shaft, a first gear fixedly sleeved at the bottom of the rotating shaft, the first gear meshing with the second gear.

[0006] As a further technical solution of this utility model, the stirring blades on the outer wall of the stirring rack are arranged in groups of six, and the stirring blades are distributed at equal intervals from top to bottom.

[0007] As a further technical solution of this utility model, the first gear and the second gear are at the same horizontal position, and the first gear and the second gear are the same size.

[0008] As a further technical solution of this utility model, a cross key is machined on the outer wall of the plug, and a cross groove corresponding to the cross key is opened inside the socket.

[0009] As a further technical solution of this utility model, a magnetic block is welded to the top of the scraper, and a magnetic seat is welded to the right side of the top of the reaction vessel. The magnetic seat and the magnetic block are magnetically fixed together.

[0010] As a further technical solution of this utility model, a jacket is installed on the outside of the reaction vessel, and an electric heating wire is installed inside the jacket.

[0011] As a further technical solution of this utility model, a controller is installed on the left side of the outer wall of the reactor, a heater is provided at the lower left of the reactor, and a temperature controller is installed at the bottom of the reactor.

[0012] As a further technical solution of this utility model, the jacket is covered with an insulation layer, which is made of flexible foamed silicone rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a drive motor, gear reducer, rotating shaft, first gear, second gear, cylinder, piston rod, connecting seat, sleeve, scraper, and microstructure coating, the stirring blade and scraper are both covered with a microstructure coating. The coating is made of fluorine-modified polymer microstructure material, which has low surface energy and is not easy to adhere. During stirring, the material is not easy to stick to the blade or scraper, which facilitates subsequent cleaning. Even if the stirring time is long, a thick layer of residue will not accumulate, keeping the inside of the vessel clean.

[0014] The system is equipped with a cylinder, piston rod, connecting seat, sleeve, and scraper. When scraping is not required, the scraper is attracted to the magnetic seat fixedly welded to the upper right side of the reactor via the magnetic block at its top. When scraping is required, the cylinder is activated, and the scraper is brought into the stirring trajectory and begins to follow the rotation of the stirring frame to scrape the material along the reactor wall. The entire process does not require a separate motor to drive it; it can be achieved by the original rotating structure and the cylinder action. The structure is simple and the operation is reliable.

[0015] By incorporating a jacket, heating wire, insulation layer, temperature controller, heater, and controller, the jacket is lined with heating wire to achieve uniform heating. The temperature controller monitors the temperature changes of the vessel in real time, maintaining the temperature within a relatively stable range. The insulation layer is made of flexible foamed silicone rubber with a certain thickness, providing both insulation and pressure resistance while adhering to the vessel body and preventing it from falling off. Even in winter, it ensures rapid heating and stable temperature control, saving energy and making it suitable for surfactant stirring processes with strict temperature requirements.

[0021] 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.

[0022] Please see Figure 1-4This utility model provides an embodiment of a stirring device with temperature control and surface microstructure anti-sticking functions, including a reaction vessel 1. Both sides of the bottom of the reaction vessel 1 have discharge ports 23. A rotating seat 25 is fixed to the bottom of the reaction vessel 1, and a stirring frame 12 is rotatably connected to the rotating seat 25. A plug 11 is located at the top of a controller 21, and a second gear 13 is fixedly sleeved below the plug 11. A cylinder 2 (model SMC MGPM16-25Z) with a solenoid valve is fixed to the top of the inside of the reaction vessel 1. A piston rod 3 is installed at the output end of the cylinder 2, and a connecting seat 4 is fixed to the bottom of the piston rod 3. A connecting rod 8 is fixedly connected to the right side of the connecting seat 4, and a scraper 9 is fixedly connected to the right side of the connecting rod 8. The stirring blades of the stirring frame 12 and the scraper 9 are coated with a microstructure coating 10, which is a fluorine-modified polymer microstructure material. A sleeve 5 is welded to the bottom of the connecting seat 4, and the sleeve 5 is plugged into and matched with the plug 11. A drive motor 17 (model MH) is fixedly connected to the left side of the top of the reaction vessel 1. MD042G1U, the output shaft of the drive motor 17 is connected to the gear reducer 16, which is model PG64-10. The output shaft of the gear reducer 16 extends into the reactor 1 and is fixedly connected to the rotating shaft 15. The bottom end of the rotating shaft 15 is fixedly sleeved with the first gear 14. The first gear 14 is meshed with the second gear 13. The stirring blades on the outer wall of the stirring frame 12 are grouped into six. The stirring blades are evenly distributed from top to bottom. The first gear 14 and the second gear 13 are at the same horizontal position. The first gear 14 and the second gear 13 are the same size.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive motor 17 drives the gear reducer 16 to output torque, and the rotating shaft 15 drives the second gear 13 to rotate through the first gear 14. The second gear 13 drives the stirring frame 12 to rotate, and stirring is carried out in the reaction vessel 1. Six stirring blades are installed at equal intervals on the stirring frame 12, which can disperse and mix the surfactant under high pressure. The stirring blades and scraper 9 are covered with a microstructure coating 10. The coating is made of fluorine-modified polymer microstructure material, which has low surface energy and is not easy to adhere. During stirring, the material is not easy to stick to the blades or scraper 9.

[0024] A cross key is machined on the outer wall of the plug 11, and a cross groove corresponding to the cross key is opened inside the socket 5. A magnetic block 7 is welded to the top of the scraper 9, and a magnetic seat 6 is welded to the right side of the top of the reactor 1. The magnetic seat 6 and the magnetic block 7 are magnetically fixed together.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when scraping is not required, the scraper 9 is attracted to the magnetic seat 6 fixedly welded to the upper right of the reactor 1 by the magnetic block 7 at its top. The entire scraper 9 is attached to the inner wall and does not move, which does not affect normal stirring. When scraping is required, the drive motor 17 stops. At this time, the stirring frame 12 decelerates until it slowly rotates. The cylinder 2 starts and pushes the piston rod 3 down, which drives the connecting seat 4 and the connecting rod 8 to move downward as a whole. When the plug 5 fits with the plug 11 at the top of the stirring frame 12, the scraper 9 is brought into the stirring trajectory and begins to follow the rotation of the stirring frame 12 to scrape the material along the reactor wall.

[0026] The reactor 1 is equipped with a jacket 18, and a heating wire 19 is installed inside the jacket 18. A controller 21 is installed on the left side of the outer wall of the reactor 1. A heater 22 is installed on the lower left side of the reactor 1. A temperature controller 24, model E5CC-RX2ASM-800, is installed at the bottom of the reactor 1. The jacket 18 is covered with a heat insulation layer 20, which is made of flexible foamed silicone rubber.

[0027] Specifically, such as Figure 1 As shown, the reactor 1 is covered with a jacket 18, and heating wires 19 are laid inside the jacket 18 to achieve uniform heating. The temperature controller 24 detects the temperature change of the reactor body in real time and transmits the signal to the controller 21. The controller 21 adjusts the on / off state of the heater 22 according to the set value to keep the temperature in a relatively stable range. The reactor body is then covered with an insulation layer 20. This insulation layer 20 is made of flexible foamed silicone rubber, has a certain thickness, is both heat-insulating and pressure-resistant, and can adhere to the reactor body and is not easy to fall off.

[0028] Working principle: After the drive motor 17 starts, it outputs power to the gear reducer 16. The gear reducer 16 converts high-speed rotation into low-speed, high-torque output, driving the rotating shaft 15 to rotate. The bottom end of the rotating shaft 15 is fixed with a first gear 14, which meshes with the second gear 13 on the top of the stirring frame 12. Through gear transmission, the stirring frame 12 rotates at a constant speed around the central axis. Multiple sets of stirring blades installed on the stirring frame 12 rotate simultaneously, realizing continuous stirring of the material inside the reactor 1. When a wall scraping action is required, the PLC controller 21 outputs a control signal to control the solenoid valve to switch, the cylinder 2 starts and pushes the piston rod 3 downward, driving the connecting seat 4 and the connecting rod 8 to move downward as a whole. The drive motor 17 stops rotating. At this time, the stirring frame 12 decelerates until it reaches its maximum speed. When the plug 11 on the top of the stirring rack 12 is inserted and matched with the plug 5 slowly, the scraper 9 is brought into the stirring trajectory and begins to follow the rotation of the stirring rack 12 to scrape the material along the reactor wall. When the scraping action is completed, the cylinder 2 retracts and the piston rod 3 drives the scraper 9 to rise back to its original position. The magnetic block 7 is re-adsorbed on the magnetic seat 6, the scraper 9 stops rotating, and the normal stirring state is restored. The temperature control part collects the temperature data of the outer wall of the reactor 1 in real time through the temperature controller 24 and transmits the signal to the controller 21. The controller 21 outputs a control signal to the heater 22 according to the set temperature value, which controls the on and off of the electric heating wire 19 inside the jacket 18, thereby heating the inner wall of the jacket 18. The temperature of the reactor 1 gradually increases, and the insulation layer 20 covers the outside of the jacket 18 to form a closed insulation structure.
