A catalyst grinding and drying process

Abstract

The invention belongs to the technical field of catalyst preparation, and specifically relates to a catalyst grinding and drying process. The process includes the following steps: putting raw materials into a hopper of a catalyst preparation system, and entering the agitation module through the funnel to start the grinding and drying process of the catalyst; There is a spiral feeding plate inside the funnel, the lower end of the spiral feeding plate is connected with a spring, the spring extends to the box and contacts the shaking plate, the distance between the springs is greater than the thickness of the shaking plate; the shaking plate is a heating plate, and the upper end of the spiral plate shaft The positive and negative electrodes are respectively connected to the lower end of the box; the lower end of the box is equipped with a No. 3 cylinder, and the tail of the No. 3 cylinder is connected to the tail of the No. 2 cylinder in the catalyst preparation system through a gas pipe. The central axis of the No. 1 cylinder is on the same horizontal line; the present invention contacts the jitter plate through the spring, and increases the jitter amplitude and frequency of the jitter plate during the rotation of the spring, thereby improving the refinement efficiency of the catalyst raw material.

Description

technical field [0001] The invention belongs to the technical field of catalyst preparation, in particular to a catalyst grinding and drying process. Background technique [0002] In a chemical reaction, a catalyst can change the chemical reaction rate of the reactants (increase or decrease) without changing the chemical balance, and a substance 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 compou...
