Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a mixing structure for reaction kettles. Background Art

[0002] At present, when manufacturing companies prepare formaldehyde-free glue, they need to use a reactor to stir the raw materials of the formaldehyde-free glue. However, when the existing reactor is stirred, due to the stickiness of the raw materials of the formaldehyde-free glue, a large amount of formaldehyde-free glue raw materials will adhere to the inner wall of the reactor. These raw materials are not only difficult to remove, but also increase the difficulty of cleaning the reactor, causing great trouble to the operators of the manufacturing companies.

[0003] According to the description of a formaldehyde-free glue reactor for automobile interior decoration disclosed on the patent website (authorization announcement number: CN209476274U), "The utility model discloses a formaldehyde-free glue reactor for automobile interior decoration, which belongs to the technical field of reactors. The formaldehyde-free glue reactor for automobile interior decoration includes a body, a sleeve box is fixedly sleeved on the outer surface of the top of the body, a top box is fixedly installed on the top of the sleeve box, and a top opening is opened on the top of the body. The number of the top openings is two, and the two top openings are symmetrical about the center of the body. A driving motor is fixedly installed on the top of the inner cavity of the sleeve box. The formaldehyde-free glue reactor for automobile interior decoration is provided with a first scraper block and a second scraper block. Due to the cooperation of the first scraper block and the second scraper block, when the driving motor rotates, the first scraper block and the second scraper block will rotate simultaneously, thereby realizing the scraping of the inner wall of the body, so that the formaldehyde-free glue raw material attached to the inner wall of the body can flow out through the discharge pipe. Not only is the structure simple and convenient for material collection, but also the formaldehyde-free glue is prevented from adhering to the inner wall of the body, thereby increasing the practicality of the reactor."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the operation of the driving motor will respectively drive the first scraper block, the second scraper block, the stirring rod and the stirring blade to rotate through the rotating shaft, so that the stirring rod and the stirring blade can evenly stir the formaldehyde-free glue raw material. However, since the formaldehyde-free glue is relatively viscous, the stirring rod and the stirring blade will cause the glue to produce a fixed flow field according to a fixed rotation direction, which is not conducive to the mixing of the viscous glue. Therefore, it is necessary to improve a mixing structure for the reactor to solve the above problem. Utility Model Content
