Description

Technical Field

[0001] This utility model relates to the field of mixing and stirring, and in particular to an automatic cleaning type continuous mixing and stirring system for polymerization inhibitors. Background Technology

[0002] In existing technologies, during industrial production, olefin monomers are highly susceptible to polymerization reactions during storage and transportation. To effectively mitigate this, polymerization inhibitors are widely used as key auxiliaries. Inhibitor molecules react with chain radicals, transforming into non-radical substances or low-reactivity radicals, thereby terminating the polymerization process. To fully utilize the effectiveness of polymerization inhibitors in olefin solutions, they must be dissolved as uniformly as possible, which relies on efficient stirring and blending operations.

[0003] However, existing polymerization inhibitor mixing reactors have several problems that urgently need to be addressed. Firstly, during operation, traditional stirring devices tend to cause the polymerization inhibitor and raw materials to adhere to the inner wall of the reactor, resulting in significant material waste, increased production costs, and, over time, potential equipment damage due to material agglomeration, shortening equipment lifespan. For example, some reactors have experienced corrosion and wear on their inner walls due to material adhesion and agglomeration. Secondly, some stirring devices have poor stirring effects, failing to ensure thorough mixing of the polymerization inhibitor and solution, thus preventing the inhibitor from achieving its maximum effectiveness and impacting product quality and production efficiency. Thirdly, the vibration generated by the stirring motor is often transmitted throughout the entire stirring device casing, causing shaking and leading to safety hazards such as equipment displacement and loose connections. In severe cases, this can even cause equipment failure and threaten the safety of operators.

[0004] Furthermore, in reactions involving polymerization inhibitor modification, traditional reaction equipment suffers from slow material reaction and uneven contact with reactants, resulting in incomplete reactions and unstable product quality. Simultaneously, the adhesion of polymerization inhibitors to the inner wall of the reactor greatly increases the difficulty of cleaning. If cleaning is incomplete, residual polymerization inhibitors will affect subsequent use and product quality, leading to adverse consequences such as decreased product purity and performance fluctuations.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] 1. Due to the coordinated operation of the agitator and cleaning component, the rotating component, through the meshing of gears and racks, drives the agitator to mix the materials inside the tank while simultaneously driving the cleaning component to rotate along the first groove on the tank's side wall. The scraper and rubber strip on the cleaning component promptly remove the polymerization inhibitor and raw materials adhering to the inner side wall of the tank, preventing material residue and reducing waste. Simultaneously, it ensures that the materials are always in a good mixing environment during the mixing process, improving the mixing efficiency and uniformity of the polymerization inhibitor and solution, effectively solving the problems of insufficient mixing and material residue in traditional devices. The buffer block between the scraper and rubber strip in the cleaning component allows the rubber strip to flexibly avoid hard impurities, preventing damage from excessive compression or collision, and significantly extending the service life of the cleaning component. This design ensures long-term stable operation of the cleaning component, reduces equipment maintenance frequency and costs, and avoids problems such as decreased cleaning effect and increased material residue caused by damage to the cleaning component. The semi-circular pressure strip on the rubber strip increases the friction with the inner side wall of the tank, allowing the rubber strip to fit more tightly against the tank surface, effectively removing stubborn adhering material impurities. Meanwhile, the nozzles on the top and sides of the scraper can spray cleaning fluid between the rubber strip and the inner wall of the tank, further softening and flushing away impurities. This dual action significantly improves the cleaning effect of the tank and reduces the risk of residual materials affecting subsequent production and product quality. Attached Figure Description

A first groove 11 is provided on the inner side wall of the tank 1. The cleaning component 3 slides along the first groove 11. The rotating component 4 is disposed on the side wall of the tank 1 and its working end engages with the stirring component 2.

[0024] The cleaning component 3 includes a rotating bar 31, a scraper 32 disposed on the rotating bar 31, and a rubber strip 33 for scraping impurities from the inner wall of the tank 1; the rotating bar 31 rotates within the first groove 11; the scraper 32 is arranged in a circumferential array on the rotating bar 31; the scraper 32 is L-shaped; and the rubber strip 33 corresponds to the outer wall of the scraper 32.

[0025] A buffer block 34 is provided between the scraper 32 and the rubber strip 33; when the rubber strip 33 encounters hard impurities, the rubber strip 33 avoids the hard impurities through the buffer block 34, thereby preventing the rubber strip 33 from being damaged.

[0026] The rubber strip 33 is provided with pressure strips 35 to increase friction; several pressure strips 35 are arranged in an array and the pressure strips 35 are parallel to the rotation axis; the pressure strips 35 are semi-circular.

[0027] A rack 36 is provided on the side wall of the rotating bar 31; the rack 36 covers the rotating bar 31; a gear 41 is provided on the working end of the rotating component 4; a second groove 12 is opened on the side wall of the first groove 11; the gear 41 is embedded in the second groove 12; the gear 41 meshes with the rack 36; the rotating component 4 drives the gear 41 to rotate, thereby driving the rubber strip 33 to fit against the inner side wall of the tank 1 and cleaning the inner side wall of the tank 1.

[0028] Each set of scraper blades 32 is equipped with a nozzle 37 at the top; nozzles 37 are also provided on both sides of the scraper blades 32; the nozzles 37 face the space between the rubber strip 33 and the inner wall of the tank 1.

[0029] The agitator 2 and the cleaning component 3 work together. The rotating component 4, through the meshing of gear 41 and rack 36, drives the agitator 2 to mix the material in the tank 1 while simultaneously driving the cleaning component 3 to rotate along the first groove 11 on the side wall of the tank 1. The scraper 32 and rubber strip 33 on the cleaning component 3 can promptly scrape off the polymerization inhibitor and raw materials adhering to the inner side wall of the tank 1, avoiding material residue and reducing waste. At the same time, it ensures that the material is always in a good mixing environment during the mixing process, improving the mixing efficiency and uniformity of the polymerization inhibitor and the solution, and effectively solving the problems of insufficient mixing and material residue in traditional devices.

[0030] Because the agitator 2 and the cleaning component 3 work together, the rotating component 4, through the meshing of gear 41 and rack 36, drives the agitator 2 to mix the material inside the tank 1 while simultaneously driving the cleaning component 3 to rotate along the first groove 11 on the side wall of the tank 1. The scraper 32 and rubber strip 33 on the cleaning component 3 can promptly scrape off the polymerization inhibitor and raw materials adhering to the inner side wall of the tank 1, avoiding material residue and reducing waste; at the same time, it ensures that the material is always in a good mixing environment during the mixing process, improving the mixing efficiency and uniformity of the polymerization inhibitor and the solution, effectively solving the problems of insufficient mixing and material residue in traditional devices; the buffer block 34 set between the scraper 32 and the rubber strip 33 in the cleaning component 3 allows the rubber strip 33 to flexibly avoid hard impurities, preventing the rubber strip 33 from being damaged due to excessive compression and collision, and significantly extending the service life of the cleaning component. This design ensures the long-term stable operation of the cleaning component 3, reduces equipment maintenance frequency and costs, and avoids problems such as decreased cleaning effect and increased material residue caused by damage to the cleaning component. The semi-circular pressure strip 35 set on the rubber strip 33 increases the friction with the inner wall of the tank 1, allowing the rubber strip 33 to fit more tightly against the surface of the tank 1, effectively removing stubborn material impurities. At the same time, the nozzles 37 set on the top and sides of the scraper 32 can spray cleaning fluid between the rubber strip 33 and the inner wall of the tank 1, further softening and flushing impurities. The dual action greatly improves the cleaning effect of the tank 1 and reduces the risk of residual material affecting subsequent production and product quality.
