Description

Technical Field

[0001] This utility model relates to the technical field of stabilizer production equipment, and in particular to a multifunctional reaction device for PVC heat stabilizers. Background Technology

[0002] PVC (polyvinyl chloride) is a widely used thermoplastic, but it is prone to decomposition when heated during processing, releasing harmful substances such as hydrogen chloride, leading to deterioration of material properties. Therefore, heat stabilizers are needed in PVC processing to inhibit thermal decomposition and improve its thermal stability and processing performance. There are many types of PVC heat stabilizers, including organotin compounds, calcium-zinc composites, and rare earth compounds, and their preparation involves complex chemical reactions and high-precision control. To ensure the stability, uniformity, and product quality of the heat stabilizers, specialized multifunctional reaction equipment is required for synthesis and processing to meet the requirements of industrial production.

[0003] Existing multifunctional reaction devices for PVC heat stabilizers typically employ reactors with stirred paddles to achieve uniform mixing of raw materials. Furthermore, some devices are equipped with vacuum systems to reduce impurity formation and improve product purity. While these devices can meet the production needs of most PVC heat stabilizers, the fixed position of the stirring blades on the stirring rod prevents adjustment when the amount of raw materials changes. Therefore, a multifunctional reaction device for PVC heat stabilizers is proposed to address these issues. Utility Model Content

[0029] 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.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a multifunctional reaction device for PVC heat stabilizers, comprising a reaction tank 1, a tank cover 2 on the top of the reaction tank 1, a motor 3 on the top of the tank cover 2, a stirring assembly connected to the output end of the motor 3, and an anti-sticking assembly inside the reaction tank 1; the stirring assembly includes a stirring rod 4, which is disposed inside the reaction tank 1, one end of the stirring rod 4 is connected to the output end of the motor 3, a sliding ring 6 is provided on the side wall of the stirring rod 4, a connecting rod 7 is fixedly connected to the side wall of the sliding ring 6, a conical stirring blade 8 is fixedly connected to the side wall of the connecting rod 7, a bolt 9 is provided inside the sliding ring 6, a bolt hole 10 is opened inside the stirring rod 4, a plug 11 is provided inside the bolt hole 10, a limiting strip 5 is fixedly connected to the side wall of the stirring rod 4, and the sliding ring 6 is slidably connected to the side wall of the stirring rod 4 and the limiting strip 5;

[0031] When processing PVC heat stabilizers using this equipment, to ensure optimal mixing, the spacing between the upper and lower sets of conical mixing blades 8 can be adjusted according to the amount of raw material. During adjustment, first remove the plug 11 from the bolt hole 10 to ensure smooth operation. Then, unscrew the bolt 9 from the bolt hole 10. Next, slide the sliding ring 6 to change the position of the conical mixing blades 8. During sliding, the limiting strip 5 acts as a limit, effectively preventing the sliding ring 6 from shifting and ensuring that the bolt 9 and the bolt hole 10 are always on the same axis, thus improving operational stability. After the sliding ring 6 reaches the ideal height, precisely screw the bolt 9 into the corresponding bolt hole 10 and ensure it is securely tightened to prevent loosening during equipment operation and affecting the mixing effect. Finally, insert the plug 11 into the remaining bolt holes 10. Through this series of adjustment steps, not only can the spacing of the conical mixing blades 8 be optimized, but the uniformity of raw material mixing and processing efficiency can also be significantly improved, providing a reliable guarantee for subsequent processes.

[0032] Reference Figures 1-3 The anti-adhesion assembly includes a connecting shaft 13, which is fixedly connected to the bottom of the stirring rod 4. A scraper 14 is fixedly connected to the bottom of the stirring rod 4, and a scraper 25 is fixedly connected to the top of the scraper 14. The scraper 14 is in contact with the bottom of the inner wall of the reaction vessel 1, and the scraper 25 is in contact with the inner side wall of the reaction vessel 1. A cavity 12 is provided inside the reaction vessel 1, and a heating wire 16 is provided inside the cavity 12. Both ends of the heating wire 16 penetrate the side wall of the reaction vessel 1 and extend to the outside. A heat insulation plate 17 is fixedly connected to the side wall of the reaction vessel 1, and a heater 18 is provided outside the heat insulation plate 17. The heater 18 is connected to the heating wire 16. A plug 19 is provided inside the lid 2, and a pull ring 20 is fixedly connected to the top of the plug 19.

[0033] During the rotation of the stirring rod 4 driven by the starting motor 3, the connecting shaft 13 simultaneously drives the scraper blades 14 and 15 to rotate, efficiently scraping away the raw materials adhering to the inner wall of the reaction vessel 1. This design ensures that the inner wall of the reaction vessel 1 remains clean, preventing raw material residue from affecting subsequent processes. Simultaneously, the rotation of the stirring rod 4 promotes uniform mixing of the raw materials within the reaction vessel 1, significantly improving mixing efficiency and processing efficiency. At the same time, the heater 18 can be activated, uniformly heating the interior of the reaction vessel 1 under the action of the heating wire 16. This heating process not only helps reduce the adhesion of the raw materials, further improving the scraping effect, but also promotes the reaction rate and mixing uniformity between materials, thereby ensuring the high efficiency and quality stability of the entire process. Through the synergistic effect of stirring, scraping, and heating, the processing effect is improved.

[0034] Working principle: When using this equipment to process PVC heat stabilizer, first adjust the interval between the upper and lower sets of conical stirring blades 8 according to the amount of raw material placed to achieve the best stirring effect. When adjusting, first remove the plug 11 from the plug hole 10, then unscrew the bolt 9 from the plug hole 10, and then slide the sliding ring 6 to change the position of the conical stirring blades 8. During this process, the limiting strip 5 achieves the limiting effect, ensuring that the bolt 9 and the plug hole 10 are on the same axis during the sliding of the sliding ring 6. When the sliding ring 6 moves to the appropriate height, screw the bolt 9 into the corresponding plug hole 10. Finally, insert the plug 11 into the remaining plug holes 10 to complete the adjustment of the conical stirring blades 8.

[0035] During the process of starting the motor 3 and driving the stirring rod 4 to rotate, the connecting shaft 13 will simultaneously drive the scraper 14 and scraper 2 15 to rotate, scraping off the raw materials attached to the inner wall of the reaction vessel 1. At the same time, the heater 18 can be started, and the interior of the reaction vessel 1 can be heated in conjunction with the heating wire 16 to improve the scraping effect and improve the mixing efficiency.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
