Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, specifically to a mixing device for epoxide alkane materials. Background Technology
[0002] Polyepoxides are obtained by initiating the ring-opening reaction of monoepoxides such as epoxides with an initiator. They are liquid at room temperature, and because their cured form remains flexible even at low temperatures, they can be widely used as raw materials for sealing materials, adhesives, etc. In the preparation of polyepoxides, an initiator needs to be added to ensure that the initiator and a certain amount of epoxides coexist. Subsequently, heating is used to enable the catalyst to exhibit polymerization activity. Therefore, in the preparation of polyepoxides, the initiator and epoxides need to be mixed evenly before adding the catalyst.
[0003] However, at higher temperatures, ethylene oxide is prone to significant vaporization during mixing, and the vaporized ethylene oxide is detrimental to subsequent polymerization reactions. Therefore, we propose a mixing device for ethylene oxide materials. Utility Model Content

[0031] In this invention, during use, the motor 401 drives the rotating shaft 402 and the stirring rod 403 to rotate, causing the stirring rod 403 to mix the materials. The stirring rod 403 drives the rotating ring 405, the mixing arc plate 406, and the disturbance arc plate 407 to rotate. The mixing arc plate 406 disturbs the materials inside the inner vessel 1. The arc-shaped mixing arc plate 406 pushes the materials above down, thereby promoting the full mixing of the materials above and below. This ensures that the materials in the vessel are dispersed and mixed in both the axial and radial directions, enhancing the stirring efficiency and preventing stratification. The cooling water between the outer vessel 3 and the inner vessel 1 cools the materials in the inner vessel 1. The disturbance arc plate 407 disperses the cooling water, pushing the cooling water below up, thereby promoting the full mixing of the cooling water above and below, improving the uniformity of the cooling water temperature, and reducing the probability of material vaporization.
