Visual experimental equipment and visual experimental method for researching dispersing action mechanism of grinding sheet

Abstract

The invention provides visual experimental equipment and a visual experimental method for researching the dispersing action mechanism of a grinding sheet. The visual experimental equipment comprises adisc grinding mechanism and a data collection mechanism, wherein the disc grinding mechanism comprises a base, a static sheet assembly and a dynamic sheet assembly, the static sheet assembly and thedynamic sheet assembly are arranged on the base, and the tail end of a main shaft positioned at one side of the dynamic sheet assembly is connected with a motor through a coupler; the data acquisitionmechanism comprises a current detection device, a rotating speed control device and a shooting machine which are sequentially connected with the motor, and the shooting machine is arranged above thedisc grinding mechanism; and the data acquisition mechanism is externally connected with an experimental data processing system. The visual experimental method comprises the following steps: adjustingthe distance between a dynamic grinding sheet and a static grinding sheet according to the concentration of pulp; then respectively acquiring image data of a pulp grinding condition, current data ofthe motor and rotating speed data by the data collection mechanism in the pulp grinding process, and transmitting the image data of the pulp grinding condition, the current data of the motor and the rotating speed data to the experimental data processing system for processing and analyzing. The visual experimental equipment has simple structure, convenient use and simple operation method and can be well used for researching the dispersing mechanism of a heat disperser in a laboratory.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a visualization experimental equipment and method for research on the mechanism of dispersion of abrasive discs. Background technique [0002] The dispersion of pulp is an important process in the papermaking process. At present, the heat dispersing machines used at home and abroad include roller heat dispersing machines and disc heat dispersing machines. The machine is low, the operating temperature of the disc heat disperser is between 90°C and 130°C, and the operating temperature of the roller heat disperser is lower than 100°C. According to the experience and data at home and abroad, in the waste paper processing system, the disc heat disperser has a certain advantage in the treatment effect of stickies than the roller heat disperser. When using waste paper as raw material to produce medium and high-grade paper, Commonly used is a disc heat disperser. However, there are...
