A high-efficiency catalyst fine grinding device for chemical experiments

Abstract

The invention discloses an efficient catalyst fine grinding device for a chemical experiment. The efficient catalyst fine grinding device comprises a damping plate, a damping spring A, a grinding box,a fixed abrasive disk, a rotary abrasive disk, a screening box, a movable sliding frame and impacting heads. The damping spring A is further connected between the damping plate and a base. An elasticgasbag A is further arranged between the damping plate and the base. The fixed abrasive disk is further arranged in the grinding box. An extending shaft of a first driving motor penetrates through ashaft hole in the center of the fixed abrasive disk, and the rotary abrasive disk is connected to the lower portion of the fixed abrasive disk. Jacking rods are welded to both the left side and the right side of the movable sliding frame. The impacting heads are further in threaded connection with the other ends of the jacking rods. In the efficient catalyst fine grinding device, left and right moving of the movable sliding frame is achieved, thus on the one hand, left and right moving of the screening box can be achieved, so that catalyst screening efficiency is improved greatly; and on the other hand, the impacting heads on the left side and the right side can be driven to impact on the inner wall of the grinding box, adhesion of catalyst powder on the inner wall of the grinding box is avoided effectively, and simple and effective effects are achieved.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a high-efficiency catalyst fine grinding device for chemical experiments. Background technique [0002] In a chemical reaction, a substance that can change the chemical reaction rate of the reactants (both increase and decrease) without changing the chemical balance, and whose quality and chemical properties have not changed before and after the chemical reaction is called a catalyst. The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is like the relationship between a lock and a key, with a high degree of selectivity (or specificity). [0003] The existing high-efficiency catalyst grinding device has the disadvantages of time-consuming and laborious grinding, poor grinding effect, and slow grinding speed. At the same time, it cannot screen the ground catalyst and cannot meet the r...
