Description

Technical Field

[0001] The utility model relates to the field of chemical intermediate synthesis reaction, in particular to a liquid flow battery electrolyte intermediate 4,4-bipyridine synthesis reaction device. Background Art

[0002] As an organic synthesis intermediate, 4,4'-bipyridine is mostly used for the synthesis and modification of pyridine ligands in organic chemical reactions. It can also be used as a ligand unit in supramolecular chemistry and assembled into supramolecular compounds with metal complexes. Since there is a lone pair of electrons on the pyridine nitrogen atom in its structure, it can be used as an organic ligand in metal catalytic reactions. In addition, in some organic chemical reactions, the compound can also be used as an acid binding agent to capture acidic substances produced in the reaction system. In the preparation process of 4,4'-bipyridine, the synthesis reaction is an indispensable link, and the synthesis reaction device is indispensable. In the synthesis reaction, a reactor is required for reaction synthesis. When the existing chemical reactor is used for mixing and stirring solid particles, it generally uses a single stirring rod controlled by a motor for stirring and mixing, and these solid particles may have agglomeration.

[0003] According to the published patent 202211151177.2, a chemical reactor with agglomeration breaking function and efficient distribution function includes a reactor body, a rotating motor is fixed at one end of the reactor body away from the warehouse door, a plurality of hemispherical extrusion blocks are fixed on the inner wall of the reactor body, and a glob breaking device is arranged inside the reactor body, and the glob breaking device includes a rotary rod, and three stirring plates are fixed outside the rotary rod. The present application breaks up the agglomerated solid particles in the reactor body by setting up a glob breaking device, and the extrusion block cooperates with the plurality of hemispherical extrusion blocks fixed on the inner wall of the reactor body to make the plurality of crushing breaking cones break up the agglomerated solid particles on the stirring plate, thereby solving the problem that a single stirring rod in the prior art does not have the function of breaking up the agglomerated solid particles. In the process of realizing the present utility model, the inventor found that at least the following problems in the prior art have not been solved: although the agglomeration breaking device is provided to break up the agglomerated solid particles in the reactor body, ... The spherical extrusion block cooperates with multiple crushing and breaking cones to break up the agglomerated solid particles on the stirring plate, solving the problem that the single stirring rod in the prior art does not have the function of breaking up the agglomerated solid particles. During use, the traditional liquid flow battery electrolyte intermediate 4,4-bipyridine synthesis reaction device squeezes the agglomerated chemical particle raw materials after the materials enter the reactor body during the reaction process. However, the extrusion distance is fixed, resulting in the agglomerated chemical raw materials near the edge of the tank or the agglomerated materials less than the extrusion distance. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content
