Description

Technical Field

[0001] The utility model relates to the field of inner wall cleaning of a reaction kettle, in particular to a device for cleaning particles on the inner wall of a reaction kettle. Background Technique

[0002] A reaction kettle is a comprehensive reaction vessel. According to different process condition requirements, the structural design and parameter configuration of the vessel are carried out to achieve the heating, evaporation, cooling and low-high speed mixing reaction functions required by the process. With the increase of the number of reactions, the crystal nuclei adsorbed on the inner wall of the reaction kettle grow larger and larger, forming irregular massive ternary precursors, which eventually peel off from the inner wall of the reaction kettle and mix into the finished product, resulting in a decline in the performance of the product. In the prior art, in order to remove the massive materials adsorbed on the inner wall of the reaction kettle, mostly a combination of acid soaking and pure water flushing, as well as the method of using an external cleaning device for cleaning are adopted. Such methods have problems such as long time consumption, poor effect and occupying space.

[0003] Chinese Patent Grant Publication No.: CN202221666996.6 provides a reaction kettle with a self-cleaning device. In this solution, a second stirring shaft is arranged at the bottom of the reaction kettle, the upper end of the second stirring shaft is connected to an arc-shaped rigid cross beam, both ends of the cross beam are connected to scraping plates, and one side of the scraping plate is in close contact with the inner wall of the kettle body. When the second stirring shaft at the bottom of the reaction kettle starts to rotate, the scraping plates will scrape off the massive materials on the inner wall of the reaction kettle body. This technical solution solves the problems that the product quality of the existing reaction kettle deteriorates due to the difficulty in cleaning the massive materials adsorbed on the inner wall and the external cleaning device occupying the working space.

[0004] However, in actual use, the cleaning structure of the reaction kettle with a self-cleaning device mentioned in the above patent is not convenient to assist the reaction kettle in reacting during the reaction of the reaction kettle, and the reaction materials are also likely to remain on the cleaning structure and affect the reaction. Therefore, it is necessary to provide a device for cleaning particles on the inner wall of a reaction kettle to solve the above technical problems. Content of the Utility Model

[0021] The motor 504 drives the connecting shaft 506 automatically. The connecting shaft 506 drives the driving gear 507 to rotate. The driving gear 507 drives the driven gear 508 to rotate. The driven gear 508 undergoes a rotational displacement under the influence of the internal gear ring 509. Therefore, the driven gear 508 drives the stirring and scraping blade 512 to rotate both self - rotationally and revolutionally. While the stirring and scraping blade 512 rotates both self - rotationally and revolutionally, it scrapes the inner wall of the kettle body 1, cleaning the inner wall of the kettle body 1, preventing residual particles on the inner wall of the kettle body 1, and when stirring the material, it can improve the stirring efficiency of the material and prevent the material from sticking to the wall and affecting the mixing of the material.
