[0001] The utility model relates to the technical field of trimethylguanidine production, in particular to an assembled scraper device which is easy to maintain. Background Art

[0002] During production, trimethylguanidine is an intermediate of the herbicide cyclohexanone. Its preparation method is to add methyl carbamate and dimethylamine hydrochloride into a reactor, react for 6 hours under stirring at 80-100°C, cool, add alkali solution, extract with chloroform, and obtain the finished product after desolventizing the chloroform extract. A scraper is then used to stir and react the materials. There is a stirring paddle in the scraper. The volume is increased with each section of the cylinder for easy disassembly and transportation. The higher it is loaded, the larger the volume. Conversely, the lower it is, the smaller the volume is, depending on the actual production needs of the enterprise.

[0003] The scraper is composed of a base cylinder and multiple groups of section cylinders stacked to adjust the volume of the scraper. However, as the volume and height of the scraper change, the sealing performance of the base cylinder and the section cylinder, as well as the joints between the upper and lower adjacent section cylinders need to be guaranteed. In addition, after multiple groups of section cylinders are stacked, the heat is easily distributed unevenly during the stirring process, and impurities are easily attached to the inner wall of the section cylinder, making it difficult to clean and maintain.

[0004] Therefore, in view of this, the existing structure is not enough to be studied and improved, and an assembled scraper device that is easy to maintain is proposed. Utility Model Content
