Technical Field
[0001] This utility model relates to the field of cellulose ether technology, specifically a cellulose ether reaction apparatus. Background Technology
[0002] Cellulose ethers are high molecular weight compounds obtained by chemical modification based on cellulose. Their main characteristics include good water solubility, thickening properties, adhesiveness, and biocompatibility. They are widely used in many fields, such as thickeners and water-retaining agents in building materials, drug gelling and sustained-release agents in the pharmaceutical industry, thickeners and texture improvers in the food industry, and thickeners and emulsifiers in personal care products. The cellulose ether reaction apparatus is the key equipment for the synthesis of cellulose ethers. It involves chemically reacting cellulose with etherifying reagents under specific reaction conditions. The apparatus typically consists of a reaction vessel, a stirring system, a temperature control system, a feeding system, and an exhaust and condensation device to ensure uniform mixing of reactants and appropriate temperature and pressure control.
[0003] However, in actual operation, the equipment cannot fully mix the cellulose ether, which can easily lead to uneven mixing and affect the quality of the final product. At the same time, the equipment has limited mixing power, resulting in low mixing efficiency and affecting the overall production rate.
[0004] Therefore, this invention provides a cellulose ether reaction apparatus to solve the above-mentioned problems. Utility Model Content

[0016] (III) Beneficial Effects
[0017] 1. The mixing drum is driven to rotate by the first motor and the stirring assembly to centrifuge the cellulose ether inside. Then, the rotating blades rotate in the opposite direction to mix the cellulose ether, thereby strengthening the mixing force and improving the stirring efficiency, thus increasing the overall production rate. At the same time, the rotating blades drive the cellulose ether to move and mix from the bottom, and the first motor can drive the entire cellulose ether to mix, thus effectively ensuring the uniformity of mixing and avoiding the existence of mixing dead zones, which would lead to uneven mixing and affect the quality of the final product.
[0018] 2. Through the set segmentation component, the scraper is in close contact with the inner wall of the mixing cylinder, which can prevent cellulose ether from adhering to the inner wall and making it difficult to mix effectively. Furthermore, the vertical plate is driven by the rotating rod to segment the cellulose ether, preventing it from adhering and clumping together, further ensuring the uniformity of mixing and ensuring product quality.

When an external power source starts the first motor 2, it drives the mixing drum 3 to rotate, thereby centrifugally mixing the cellulose ether inside. Then, when an external power source starts the second motor 4, it drives the rotating blade 6 to rotate via the rotating rod 5. The rotating blade 6 then rotates in the opposite direction to mix the cellulose ether, thereby strengthening the mixing force and improving the mixing efficiency, thus increasing the overall production rate. At the same time, the rotating blade 6 drives the cellulose ether to move and mix from the bottom end, and the first motor 2 can drive the entire cellulose ether to mix, thereby effectively ensuring the uniformity of the mixture and avoiding the existence of mixing dead zones, which would lead to uneven mixing and affect the quality of the final product.

The fixing ring 12 supports and protects the outer surface of the mixing cylinder 3 to prevent it from tilting. The rotating cylinder 11 fits against the outer surface of the mixing cylinder 3 to avoid restricting the rotation of the mixing cylinder 3 and to ensure the stability of the mixing cylinder 3 when it rotates.
[0031] Support legs 14 are fixedly connected to the four corners of the lower surface of the mounting platform 1. Fixing plates 15 are fixedly connected to the lower surface of the support legs 14. The support legs 14 support the mounting platform 1 and reserve space for the installation of the first motor 2. The upper surface of the fixing plate 15 has a mounting groove. Bolts are provided to pass through the mounting groove to fix the fixing plate 15, so that the mounting platform 1 can be set stably and avoid the first motor 2 from tilting when it rotates.

Next, start the first motor 2 with an external power supply to drive the mixing cylinder 3 to rotate. At the same time, start the second motor 4 with an external power supply to drive the rotating blade 6 to rotate via the rotating rod 5. The rotating blade 6 mixes the raw materials by rotating in the opposite direction. The rotating rod 5 can also drive the extension rod 8, scraper 9 and vertical plate 10 to rotate synchronously. The scraper 9 is in contact with the inner wall of the mixing cylinder 3 to prevent cellulose ether from adhering to the inner wall. The vertical plate 10 can divide the cellulose ether.
