[0002] Polymer abrasives, as advanced abrasives carefully crafted from thermoplastic acrylic plastics or polymeric thermosetting amine resins, exhibit unparalleled application advantages and broad prospects in the industrial field due to their precisely regulated hardness and density characteristics, as well as their unique polygonal angular structure design. With the increasing complexity of industrial applications, the demand for refined performance of polymer abrasives continues to rise, making modification technology a key element in improving their overall performance.

[0022] Reference Figure 1-2 A polymer abrasive modification reaction device is designed to provide a stable and efficient environment for the modification reaction of polymer abrasives, effectively improving the modification effect. Specifically:

[0023] The device includes a support frame 1 and a reaction vessel 2 vertically fixed on the support frame 1. The support frame 1 serves as the supporting foundation for the entire device and adopts a stable structural design to ensure the stability of the device during operation. The reaction vessel 2 is vertically fixed on the support frame 1, providing a closed and controllable space for the modification reaction. A jacket 3 for temperature regulation is also fitted on the outside of the reaction vessel 2. An output pipe is installed on the upper part of the jacket 3, and an input pipe is installed on the lower part of the jacket 3, which facilitates heating or cooling of the reaction vessel 2 by introducing hot or cold water into the jacket 3. An insulation layer 4 is fitted on the outside of the jacket 3. The insulation layer 4 can effectively reduce heat loss, improve the efficiency of temperature regulation, and reduce energy consumption.

[0024] A vertically extending upper support shaft 5 is rotatably installed at the top of the reactor 2, and a vertically extending lower support shaft 6 is rotatably installed at the bottom of the reactor 2. A horizontally arranged upper support pipe 7 is installed on the upper support shaft 5 inside the reactor 2, and a horizontally arranged lower support plate 8 is installed on the lower support shaft 6 inside the reactor 2. Vertically arranged side support pipes 9 are fixedly connected between the upper support pipe 7 and the lower support plate 8 on both sides. The upper support shaft 5, lower support shaft 6, upper support pipe 7, and lower support plate 8 form a three-dimensional stirring frame, which facilitates rotation inside the reactor 2, allowing the materials inside the reactor 2 to be fully stirred and improving the uniformity of the reaction. Preferably, a driving device 15 for driving the rotation of the lower support shaft 6 is installed at the bottom of the reactor 2. More preferably, the driving device 15 is a geared motor, and the motor shaft of the geared motor is connected to the lower support shaft 6. Rotary dynamic seals are installed at the junctions of the upper support shaft 5, the lower support shaft 6, and the reactor 2.

[0025] Ultrasonic auxiliary function: Several ultrasonic transducers 12 are installed between the side support tubes 9. The ultrasonic transducers 12 can generate high-frequency vibrations. This vibration can break the agglomeration of polymer abrasive and modifier molecules, promote the mixing and reaction between polymer abrasive and modifier, and further improve the modification effect. In order to protect the ultrasonic transducers 12, a protective shell can be put on the ultrasonic transducers 12. A wiring channel 13 that cooperates with the ultrasonic transducers 12 is set in the lower support shaft 6. The wires of the ultrasonic transducers 12 can be led out through the wiring channel 13, avoiding the problem of wires being tangled in the reactor 2, and ensuring the safety and reliability of the device.

[0026] Cleaning function: A water inlet channel 11 connected to the upper support pipe 7 is provided in the upper support shaft 5. The side support pipe 9 is connected to the upper support pipe 7. Several water outlet holes are also provided on the side of the side support pipe 9 to facilitate the delivery of cleaning water into the side support pipe 9 through the water inlet channel 11, so as to facilitate water spray cleaning of the side wall of the reactor 2 using the water outlet holes. Preferably, a one-way nozzle 10 is installed on the side support pipe 9 at the water outlet holes.

[0027] To enable water and electricity supply operations, a rotary joint 14 is installed at the top of the upper support shaft 5 to facilitate the connection of the water inlet channel 11 to an external water supply pipe, and a conductive slip ring 18 is installed at the bottom of the lower support shaft 6 to facilitate the connection of the ultrasonic transducer 12 to an external power source.

[0028] In actual use, a feed port for inputting polymer abrasive and modifier is set at the top of the reactor 2. The feed port is sealed by a feed cover, which makes it convenient to accurately add polymer abrasive and modifier into the reactor 2 before the reaction. At the same time, the sealed feed cover can prevent material leakage and external impurities from entering during the reaction. A discharge port with a discharge control valve 17 is set at the bottom of the reactor 2, which allows the modified polymer abrasive to be discharged from the discharge port for easy collection and treatment.

[0029] The upper support shaft 5, upper support tube 7, side support tube 9, lower support plate 8, and lower support shaft 6 are all made of stainless steel; the reactor 2 is a cylindrical stainless steel reactor 2. Stainless steel has good corrosion resistance and can adapt to the reaction environment of various chemical substances, ensuring the service life of the reactor 2 and the safety of the reaction.

[0030] The actual working process of this application is as follows:

[0031] 1. Preliminary preparations

[0032] Before using the polymer abrasive modification reaction device, the operator must conduct a comprehensive inspection of the device. Check whether the connections of each component are secure, such as the fixation of the support 1 to the reactor 2, and the connections of each pipe; check whether the rotary dynamic seal, conductive slip ring 18 and other sealing and conductive components are normal; confirm the operating status of the geared motor, ultrasonic transducer 12 and other equipment.

[0033] Prepare the polymer abrasive and modifier according to the modification process requirements, and ensure that their quality meets the requirements;

[0034] The water supply pipe is connected to the water inlet channel 11 via the rotary joint 14 at the top of the upper support shaft 5 so that hot water can be introduced into the reactor 2; the power supply of the ultrasonic transducer 12 is connected via the conductive slip ring 18 at the bottom of the lower support shaft 6 so as to provide power to the ultrasonic transducer 12.

[0035] 2. Feeding stage

[0036] The operator opens the feed cover on top of reactor 2 and adds the prepared polymer abrasive and modifier into reactor 2 through the feed inlet in a certain proportion;

[0037] After feeding is completed, close the feed cover in time to ensure that the reactor 2 is in a sealed state to prevent material leakage and external impurities from entering.

[0038] 3. Stirring and heating stage

[0039] When the geared motor is started, the motor shaft drives the lower support shaft 6 to rotate. Since the upper support shaft 5 and the lower support shaft 6 are connected to the stirring structure inside the reactor 2, the rotation of the lower support shaft 6 will drive the upper support shaft 5, the upper support pipe 7, the lower support plate 8 and the side support pipe 9 to rotate together, forming a three-dimensional stirring effect, so that the polymer abrasive and modifier are fully mixed in the reactor 2. At the same time, by introducing hot water or steam into the jacket 3, the reactor 2 is heated.

[0040] 4. Ultrasonic-assisted modification stage

[0041] While stirring and heating, the ultrasonic transducer 12 is activated. The ultrasonic transducer 12 generates high-frequency vibration, which can break the agglomeration of polymer abrasive and modifier molecules, increase the contact area between materials, promote the mixing and reaction between materials, and improve the modification effect.

[0042] 5. Reaction Stage

[0043] Under the assistance of stirring, heating and ultrasonic waves, the polymer abrasive and modifier undergo a chemical reaction in reactor 2 to achieve the modification process. The reaction time is controlled according to the specific modification process requirements.

[0044] 6. Discharge stage

[0045] After the reaction reaches the predetermined time, turn off the geared motor and stop stirring; turn off the water supply pipe and stop heating; turn off the power to the ultrasonic transducer 12 and stop ultrasonic assistance; and cool down the reactor 2 by introducing cooling water into the jacket 3.

[0046] Open the discharge control valve 17 at the bottom of reactor 2, and the modified polymer abrasive will be discharged from the discharge port under gravity. The operator can use a suitable container to collect the discharged material.

[0047] 7. Post-cleaning

[0048] Cleaning water is introduced into the water inlet channel 11 through the water supply pipe. The cleaning water enters the side support pipe 9 along the upper support pipe 7 and is sprayed out from the one-way nozzle 10 on the side of the side support pipe 9. It is evenly sprayed onto the inner wall of the reactor 2 to clean the inside of the reactor 2 and remove residual materials and impurities.

[0049] After cleaning, a comprehensive inspection and maintenance of the device is carried out to ensure that all components are operating normally and to prepare for the next use.

[0050] This polymer abrasive modification reaction device achieves efficient modification of polymer abrasives through various means such as stirring, heating, and ultrasonic assistance, and has the advantages of good modification effect and convenient operation.
