Abstract

The invention relates to a catalyst reaction device, comprising a reaction tank and a support seat fixedly supported under the reaction tank, a fixed frame is fixedly connected above the reaction tank, a first driving motor is fixedly installed on the upper end of the reaction tank, and the output of the first driving motor is The shaft is connected to the spline shaft extending to the inside of the reaction tank through the transmission mechanism. The bottom end of the spline shaft is fixed with a paddle agitator. The spline shaft is provided with a spline groove from top to bottom, and the transmission mechanism is provided with a spline groove Matching splines, one side of the spline shaft is also connected with an up and down drive mechanism that can realize the up and down movement of the spline shaft, so that the spline shaft can not only rotate with the transmission mechanism, but also move up and down at the same time, the spline shaft and the upper end of the reaction tank The connecting ports are rotationally connected by ball spline bearings. The present invention: the stirring effect of the existing organic catalyst preparation reaction device is not good, and at the same time, the stirring form cannot be switched in real time according to the viscosity change of the reaction liquid.

Description

technical field [0001] The invention belongs to the technical field of catalyst reaction, and in particular relates to a catalyst reaction device. Background technique [0002] In a chemical reaction, a substance that can change the chemical reaction rate (increase or decrease) of the reactants without changing the chemical balance, and whose quality and chemical properties have not changed before and after the chemical reaction is called a catalyst (a solid catalyst is also called a catalyst). According to statistics, more than 90% of industrial processes use catalysts, such as chemical, petrochemical, biochemical, and environmental protection. There are many kinds of catalysts, which can be divided into liquid catalysts and solid catalysts according to the state; according to the phase state of the reaction system, they can be divided into homogeneous catalysts and heterogeneous catalysts. Homogeneous catalysts include acid, alkali, soluble transition metal compounds and p...
