[0002] In the field of modified plastic production, the reaction kettle, as the core equipment, plays a crucial role in the efficiency of the production process and the quality of products. Traditional modified plastic reaction kettles face many problems that need to be solved urgently during long-term use. As the reaction progresses, various reactants, intermediate products, and by-products will gradually adhere to the inner wall of the reaction kettle. These attachments will not only affect the heat transfer and mass transfer efficiency of the reaction kettle, thereby reducing the effect of the modified plastic reaction and the product quality, but may also cause corrosion to the inner wall of the reaction kettle after long-term accumulation, shortening the service life of the reaction kettle.

[0003] At present, there are obvious deficiencies in the conventional methods for cleaning the inner wall of the reaction kettle. The commonly used manual cleaning method not only requires a large amount of labor and time costs, but also often requires the disassembly of the reaction kettle during the cleaning process. This not only makes the operation cumbersome, but may also lead to a decrease in the sealing performance of the reaction kettle due to frequent disassembly, increasing the risk of material leakage and even damaging the overall structure of the reaction kettle. In addition, although using chemical reagents for cleaning can remove attachments to a certain extent, the chemical reagents may corrode the inner wall material of the reaction kettle and also cause environmental pollution problems.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of 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 of 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.

[0025] The present invention provides an energy-saving and environment-friendly modified plastic reaction kettle device as Figure 1-7 shown, which includes a modified plastic kettle body 2 and a kettle body end cover 4 provided at the top of the modified plastic kettle body 2. Sealing docking flanges are provided on the outer part of the top of the modified plastic kettle body 2 and the outer part of the bottom of the kettle body end cover 4. The two sealing docking flanges are fixedly connected by a plurality of screws. This design realizes the tight seal between the kettle body and the end cover, prevents the leakage of materials and the entry of external impurities during the reaction process, and ensures that the modified plastic reaction is carried out in a relatively independent and stable environment. A plurality of placement supports 1 are equidistantly arranged on the circular outer wall at the lower side of the center of the modified plastic kettle body 2. The bottom ends of the plurality of placement supports 1 are provided with rectangular placement bottom plates, and the modified plastic kettle body 2 is placed on the ground through the plurality of placement supports 1 and their rectangular placement bottom plates at the bottom ends. Such a placement method can evenly disperse the weight of the reaction kettle to the ground, ensure the stability of the placement of the reaction kettle, and avoid equipment damage caused by unstable center of gravity or excessive local pressure, providing a stable basic support for the reaction process. A discharge port 11 is provided at the center of the bottom end of the modified plastic kettle body 2, and a discharge pipe 12 is connected to the bottom end of the discharge port 11. When the modified plastic reaction is completed, the qualified product is discharged from the reaction kettle through the discharge port 11 via the discharge pipe 12, realizing the smooth collection and subsequent treatment of the product. Feeding ports 5 are provided on both the front and rear sides of the center of the top end of the kettle body end cover 4. The outer opening of the top end of the feeding port 5 is hermetically sleeved with a sealing end cover 6. When it is necessary to add reactants or additives, the sealing end cover 6 is opened, and the materials enter the interior of the reaction kettle through the feeding port 5. The design of the sealing end cover 6 can prevent dust, sundries, etc. from entering the kettle body when not feeding, and at the same time maintain the stability of the reaction environment inside the kettle.

[0026] As Figure 1 , Figure 2 , Figure 3 ,Figure 4 and Figure 5 As shown in Figure 5 , a sealed drive seat 9 is provided at the center of the top end of the kettle body end cover 4. A speed reducer 8 is provided at the top end of the sealed drive seat 9, and a stirring motor 7 is provided at the top end of the speed reducer 8. The stirring motor 7 is electrically connected to an external power supply through an electric wire. A stirring shaft 15 is provided at the center of the inside of the modified plastic kettle body 2. The stirring shaft 15 is vertically arranged inside the modified plastic kettle body 2. The top end of the stirring shaft 15 is connected to the output shaft of the speed reducer 8 through the sealed drive seat 9. After the stirring motor 7 is powered on, it generates rotational power. After the power is speeded up and torque increased by the speed reducer 8, it is transmitted to the stirring shaft 15 through the sealed drive seat 9. When the stirring shaft 15 rotates driven by the power, the stirring rollers 13 rotate accordingly to fully stir the materials in the kettle. This design enables the materials to be evenly mixed in the reaction kettle, increases the contact probability between the reactants, accelerates the reaction process, and improves the efficiency and quality of the modified plastic reaction. A plurality of roller sleeves 14 are equidistantly arranged on the outside of the lower side of the center of the stirring shaft 15. A plurality of stirring rollers 13 are equidistantly arranged on the outer circular wall of the plurality of roller sleeves 14. A plurality of sensor fixing insertion cylinders 10 are provided on both the left and right sides of the center of the top end of the kettle body end cover 4. The sensor fixing insertion cylinders 10 are used to install various sensors, such as temperature sensors, pressure sensors, etc. Through these sensors, key parameters such as the temperature and pressure in the reaction kettle can be monitored in real time, providing accurate data information for the operator to timely adjust the reaction conditions to ensure that the reaction proceeds in a safe and efficient state, and at the same time helps to achieve precise control and optimization of the modified plastic reaction process.

[0027] such as Figure 1 、 Figure 6 and Figure 7As shown, an anti-destruction cleaning device 3 is connected to the outside and inside of the upper side at the center of the modified plastic kettle body 2. The anti-destruction cleaning device 3 includes a rotatable bottom ring 16, a cleaning bracket 17, a rubber cleaning blade 18, and a rotatable top ring 20. The rotatable bottom ring 16 is placed inside the bottom end of the modified plastic kettle body 2, and the rotatable bottom ring 16 can rotate clockwise and counterclockwise inside the bottom end of the modified plastic kettle body 2. A rotatable top ring 20 is arranged inside the top end of the modified plastic kettle body 2, and the rotatable top ring 20 can rotate clockwise and counterclockwise inside the top end of the modified plastic kettle body 2. A plurality of cleaning brackets 17 are equidistantly connected between the rotatable bottom ring 16 and the rotatable top ring 20. Rubber cleaning blades 18 are arranged on the outer walls of the plurality of cleaning brackets 17. A whole rotating cleaning structure is formed among the rotatable bottom ring 16, the rotatable top ring 20, and the plurality of cleaning brackets 17, providing a basic framework for subsequent cleaning operations. The anti-destruction cleaning device 3 further includes an outer clamping ring 19, a magnetic strip board 21, and a rubidium magnet 22. A magnetic strip board 21 is fixed to the bottom end of the rotatable top ring 20. Two outer clamping rings 19 are sleeved and fixed on the circular outer wall of the upper side at the center of the modified plastic kettle body 2. The two outer clamping rings 19 are symmetrically arranged up and down. A rubidium magnet 22 is arranged between the two outer clamping rings 19, and the bottom end of the rubidium magnet 22 is flush with the bottom end of the magnetic strip board 21. Anti-disengagement shafts are arranged at both the upper and lower ends of the rubidium magnet 22. Anti-disengagement chutes are arranged inside the two outer clamping rings 19, and the anti-disengagement shafts at the upper and lower ends of the rubidium magnet 22 are respectively inserted into the two anti-disengagement chutes. The rubidium magnet 22 can slide clockwise and counterclockwise around the circular outer wall of the modified plastic kettle body 2 between the two outer clamping rings 19.

[0028] As Figure 1 , Figure 6 and Figure 7As shown, the cross-sectional shape of the rubber cleaning blade 18 is triangular. One end of the triangular tip of the rubber cleaning blade 18 is closely attached to the inner wall of the modified plastic kettle body 2. The rubidium magnet 22 can magnetically adsorb the magnetic strip plate 21 through the modified plastic kettle body 2, and the magnetic strip plate 21 magnetically adsorbed by the rubidium magnet 22 can drive the rotatable bottom ring 16 and the rotatable top ring 20 to rotate clockwise and counterclockwise inside the modified plastic kettle body 2. When the operator manually or drives the rubidium magnet 22 to slide clockwise and counterclockwise around the circular outer wall of the kettle body between the two outer clamping rings 19, the rubidium magnet 22 transmits its rotational power to the rotatable top ring 20 through the magnetically adsorbed magnetic strip plate 21. Since the rotatable bottom ring 16 and the rotatable top ring 20 are connected by the cleaning bracket 17, the rotation of the rotatable top ring 20 will drive the rotatable bottom ring 16 to rotate synchronously, thereby causing the entire structure composed of the rotatable bottom ring 16, the cleaning bracket 17, and the rotatable top ring 20 to rotate clockwise and counterclockwise inside the modified plastic kettle body 2. The rubber cleaning blade 18 is arranged on the outer wall of the cleaning bracket 17, and its cross-sectional shape is triangular. One end of the triangular tip is closely attached to the inner wall of the modified plastic kettle body 2. When the structure composed of the rotatable bottom ring 16, the cleaning bracket 17, and the rotatable top ring 20 rotates inside the kettle body, the rubber cleaning blade 18 rotates with the cleaning bracket 17, and its tip part can comprehensively and carefully scrape the inner wall of the modified plastic kettle body 2. During the rotation process, it can effectively remove the residues of reactants, impurities, etc. attached to the inner wall of the kettle body, achieving the purpose of cleaning the inner wall of the kettle body, and the entire cleaning process does not require destructive operations such as disassembling the kettle body, realizing the function of non-destructive cleaning.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
