Description

Technical Field

[0001] The utility model belongs to the technical field of equipment for phosphite antioxidants, and particularly relates to a production device for phosphite antioxidants. Background Technique

[0002] Phosphite antioxidants, also known as auxiliary antioxidants, mainly function to decompose hydroperoxides. The generation and accumulation of hydroperoxides are the most critical steps in the degradation of organic polymer materials. When a certain concentration of hydroperoxides is generated, the free radical oxidation reaction will proceed rapidly. Therefore, phosphite antioxidants are crucial for inhibiting aging.

[0003] In the production process of phosphite antioxidants using existing stirring equipment, the phosphite antioxidants will remain on the inner wall of the stirring barrel, resulting in insufficient stirring, which leads to problems such as reduced antioxidant effect, decreased product quality, reduced processing efficiency, increased costs, increased environmental and safety risks, and decreased product application performance. These problems not only affect the market competitiveness of the product but may also have a negative impact on the enterprise's brand image and long-term development. Content of the Utility Model

[0004] Purpose of the utility model: To provide a production device for phosphite antioxidants, which solves the above problems existing in the prior art.

[0005] Technical solution: A production device for phosphite antioxidants includes a mounting frame, on which a stirring barrel is installed. It also includes a driving source, which is installed on the top of the stirring barrel. The output end of the driving source is connected to a transmission component, and the output end of the transmission component is connected to a double-shaft component. One output end of the double-shaft component is connected to a stirring component, which is located inside the stirring barrel. The other output end of the double-shaft component is connected to a scraping component, and part of the scraping component is in contact with the inner wall surface of the stirring barrel. Driven by the driving source, the stirring component and the scraping component rotate in opposite directions. The raw materials in the stirring barrel are stirred by the stirring component, and the raw materials remaining on the inner wall of the stirring barrel are scraped by the scraping component.

[0006] Preferably, the transmission component includes an output bevel gear, which is connected to the output end of the driving source. The output bevel gear meshes with a receiving bevel gear, and the receiving bevel gear is connected to a transmission shaft. With the mutual cooperation of the output bevel gear and the receiving bevel gear, the output end of the driving source and the transmission shaft form a cross-perpendicular state, and the output end of the transmission shaft is connected to the double-shaft component.

[0007] Preferably, the biaxial assembly includes a driving bevel gear, which is connected to the output end of the transmission assembly. The driving bevel gear meshes with two driven bevel gears, which are oppositely arranged at the edge of the driving bevel gear. One of the driven bevel gears is connected to a driven shaft, which vertically extends into the stirring barrel. The driven shaft is connected to the stirring assembly. The other driven bevel gear is connected to a driven pipe, which sleeves the driven shaft. The driven pipe is connected to the scraping wall assembly.

[0008] Preferably, the stirring assembly includes a rotating shaft, which is connected to the output end of the driven shaft. At least two mounting blocks are linearly and arrayedly installed on the rotating shaft, and stirring blades are circumferentially arrayedly installed on the outer wall of the mounting blocks.

[0009] Preferably, the scraping wall assembly includes a transverse plate, which is connected to the output end of the driven pipe. Scrapers are installed at both ends of the transverse plate. The central axis of the scraper is parallel to the central axis of the stirring barrel, and the scraper contacts the inner wall surface of the stirring barrel.

[0010] Preferably, the scraping wall assembly further includes an elastic layer, which is installed on the side of the scraper close to the inner wall of the stirring barrel.

[0011] Beneficial effects: The utility model relates to a production device for phosphite antioxidants. Driven by a driving source, the transmission assembly rotates, driving the biaxial assembly to move. One output end of the biaxial assembly is connected to the stirring assembly, which stirs the raw materials in the stirring barrel by driving the stirring assembly. The other output end of the biaxial assembly is connected to the scraping wall assembly, which scrapes the raw materials remaining on the inner wall of the stirring barrel under the action of the scraping wall assembly, effectively scraping the residues on the wall, preventing waste of raw materials and uneven mixing, not only improving the stirring efficiency and uniformity of the raw materials, but also minimizing the accumulation of materials on the wall of the stirring barrel, ensuring the cleanliness of the production process and the consistency of product quality.
