Description

Technical Field

[0001] This utility model belongs to the field of carbomer manufacturing technology, specifically relating to a carbomer vortex stirring dehydration device. Background Technology

[0002] Carbomer, also known as carbopol, is an acrylic crosslinked resin obtained by crosslinking pentaerythritol and other substances with acrylic acid. It is a very important rheology modifier. Neutralized carbopol is an excellent gel matrix with important uses such as thickening and suspending. It has a simple process, good stability, and is widely used in emulsions, creams, and gels. Carbopol is the signature product of Novogene Corporation (formerly Goodyear Corporation, one of the oldest companies in the United States). Its products include the Carbopol series of rheology modifiers and the Pemulen series of polymer emulsifiers. As a high molecular weight hydrophilic polymer, carbopol needs to be slowly dehydrated within a specific temperature range (usually 45-60℃) during the drying process. Traditional stirring structures are difficult to effectively disperse materials during the drying process, resulting in local accumulation and uneven heat transfer, reducing drying efficiency by 30%-40%. Especially in the dehydration stage, the viscosity of the material increases sharply, and the shear force generated by conventional stirring blades is insufficient to break up the gel aggregates. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a vortex stirring dehydration device that improves the efficiency of carbomer stirring.

[0004] This utility model is achieved through the following technical solution:

The device also includes a wall scraping device. The barrel wall has a double layer. The stirring rod has a structure with upper and lower blades, the upper blades being inclined at 45° on the rod body, and the lower blades being vertically mounted on the rod body. The wall scraping device is slidably mounted on the inner wall of the barrel for axial displacement and is controlled and driven by the hydraulic drive unit. The device further includes a co-control module installed on the barrel body, used to coordinate the rotational speed of the stirring rod with that of the wall scraping device. The telescopic frequency is coordinated; the wall scraping device includes a scraper, a connecting block, and a support block; the scraper is a thin-walled annular shape, and the outer wall of the scraper fits into the inner wall of the barrel; the support block is located in the middle of the scraper and is connected to the scraper through the connecting block; the hydraulic drive unit is connected to the connecting block; the scraper surface is provided with microgrooves, the depth of which is 0.2-0.5mm and the width is 1-3mm, distributed in a spiral pattern; the support block is a thin-walled annular shape, and its inner diameter is larger than the outer diameter of the upper blade; the upper blade and the lower blade adopt a gradient cross-section design, with the thickness at the end of the upper blade reduced by 40%-60% compared to the beginning, and the thickness at the end of the lower blade reduced by 20%-30% compared to the beginning; the hydraulic drive unit is a hydraulic telescopic rod; a screen is provided at the lower end of the barrel, and the screen is located above the lower blade.

[0018] The motor 5 is installed on the top of the barrel 1 and connected to the stirring rod 2.

[0019] The hydraulic drive unit 4 is located on the top of the barrel 1; the hydraulic drive unit 4 is a hydraulic telescopic rod.
