Abstract

The invention relates to the technical field of chemical engineering, in particular to a triazinone production line. The triazinone production line comprises a hydrolysis kettle, wherein an oxidationkettle is arranged on and communicates with the hydrolysis kettle through a first connecting pipe; a cyclization kettle is arranged on and communicates with the oxidation kettle through a second connecting pipe; a middle kettle is arranged on and communicates with the cyclization kettle through a third connecting pipe; the first connecting pipe, the second connecting pipe and the third connectingpipe are each provided with a first pump body and a first valve; the middle kettle is connected with a centrifugal machine through a fourth connecting pipe in a communicating mode; a solid material discharging port of the centrifugal machine is provided with a material guiding pipe in a communicating mode; the material guiding pipe is provided with an air pump; a shell is arranged on the materialguiding pipe in a communicating mode; the lower end of the shell is fixedly connected with a supporting base; the bottom wall of the shell is rotationally connected with a connecting cylinder througha sealing bearing; a plurality of connecting pipes are arranged on the connecting cylinder in a communicating mode; and the lower end of the connecting cylinder is rotationally connected with a connecting cover through the sealing bearing. The invention also provides a preparation method of triazinone. According to the invention, particulate matters are prevented from adhering to each other and becoming lumps, so product quality is not influenced.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a triazone production line and a preparation method thereof. Background technique [0002] Triazone compounds are a class of heterocyclic compounds with potential biological activity. Pymetrozine, which has insecticidal activity, is a typical representative of triazone compounds. It has the characteristics of high efficiency, low toxicity and environmental friendliness. Triazone production line It consists of hydrolysis, oxidation, cyclization, centrifugation, drying and other processes, and adopts the intermittent production process of each process. When drying triazone, the materials are piled up during drying, which will cause the moisture to not be completely discharged during drying, resulting in residual moisture, causing particles to adhere to each other and form agglomerates shape, affecting the quality of the product. Contents of the invention [0003] The purpose ...
