Reaction kettle device for production of water-soluble phenolic resin glue

Abstract

The invention discloses a reaction kettle device for the production of water-soluble phenolic resin glue. The reaction kettle device comprises a kettle body, a stirring shaft, stirrers, a motor, material dropping pipes and a material inlet pipe, wherein the stirring shaft is arranged in the kettle body, and is rotationally connected on a kettle cover of the reaction kettle; the driving motor is arranged at the top end of the stirring shaft; two layers of stirrers are arranged on the stirring shaft in the kettle body; the upper layer is a framework type stirrer, and the lower layer is a propeller type stirrer; the material inlet pipe and the two material dropping pipes are arranged on the kettle cover of the reaction kettle, and the two material dropping pipes are respectively positioned at both sides of the stirring shaft; a material outlet pipe is arranged at the bottom part of the kettle body; an annular jacket is arranged at the exterior of the kettle body; a water inlet is arranged at the bottom part of the annular jacket, and a water outlet is arranged at one side of the upper end of the annular jacket. The reaction kettle device has the advantages that by arranging the two layers of stirrers on the stirring shaft, the vertical circulation of the material in the kettle is effectively improved; by additionally arranging a spraying head at an opening of each material dropping pipe, the material dispersion speed is effectively accelerated, the reaction time is shortened, the energy source is saved, and the production efficiency of a product is improved.

Description

technical field [0001] The invention belongs to chemical equipment, in particular to a reactor device for producing water-soluble phenolic resin glue. Background technique [0002] As a polymer crosslinking agent, water-soluble phenolic resin glue is characterized by replacing a large amount of organic solvents with water, which can reduce or eliminate the pollution and waste of solvents, is beneficial to environmental protection, and can reduce production costs. It has been widely used Applications, mainly used in anti-corrosion engineering, adhesives, flame retardant material manufacturing and other industries. However, in the reactors used in the production of water-soluble phenolic resin glue in the prior art, because the reactants have a certain viscosity, there is a problem that they are not easy to be stirred evenly, and the reaction materials cannot be mixed in time and fully uniformly, resulting in a decrease in the reaction speed, resulting in a reaction. The defe...
