Grinding and drying technology for catalyst

Abstract

The invention belongs to the technical field of catalyst preparation, and particularly relates to a grinding and drying technology for a catalyst. The grinding and drying technology for the catalyst comprises the following steps that raw materials are putted into a funnel of a catalyst preparation system and then into a stirring module through the funnel to start the catalyst grinding and drying treatment; a spiral feeding plate is arranged in the funnel, springs are connected to the lower end of the spiral feeding plate, the springs extend into a box body so as to be in contact with shaking plates, and the distance between the springs is larger than the thickness of the shaking plates; the shaking plates are heating plates and the upper end and the lower end of a spiral plate rotary shaftare connected with a positive electrode and a negative electrode respectively; and a third air cylinder is arranged at the lower end of the box body, the tail part of the third air cylinder is connected with the tail parts of second air cylinders in the catalyst preparation system through air pipes, a power-on coil is arranged below a steel wire screen, and the central axis of power-on coil and the central axis of the third air cylinder are located on a same horizontal line. According to the grinding and drying technology for the catalyst, the springs are in contact with the shaking plates, the shaking amplitude and frequency of the shaking plates increase in the rotating process of the springs and the refining efficiency of the raw materials of the catalyst is improved.

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...
