Automatic impurity determinator and impurity determination method

Abstract

The invention discloses an automatic impurity determinator, which comprises a supporting cylinder and a cover plate arranged at an opening in the top part of the supporting cylinder, wherein a speed adjusting motor is arranged at the top part of the cover plate, a brush is arranged in the cover plate, an output shaft of the speed adjusting motor is vertically arranged, and the output shaft of thespeed adjusting motor extends into the cover plate and is connected with the top part of the brush; a mesh screen is arranged at an opening in the top part of the supporting cylinder, bristles of thebrush are attached to the screen surface of the mesh screen, a material receiving hopper and a material receiving cup are sequentially arranged in the supporting cylinder and located below the mesh screen, and a material taking door is arranged on the side wall of the supporting cylinder. The invention further discloses an impurity determination method using the automatic impurity determinator, and the impurity determination method realizes liberation of analysts from heavy physical work through automatic improvement of the sieving process, improves the analysis work efficiency, reduces environmental pollution, and reduces damage to the health of the analysts.

Description

technical field [0001] The invention relates to the field of powder impurity measurement, in particular to an automatic impurity tester and an impurity test method. Background technique [0002] The impurity item of carbon black is an important index to measure the quality of carbon black products, which has a significant impact on the quality of downstream products such as tires. At present, GB / T3778-2011 "Carbon Black for Rubber", GB / T7044-2013 "Pigment Carbon Black", GB / T3782-2016 "Acetylene Carbon Black", HG / T2880-2007 "Silicon Aluminum Carbon Black" and other product standards It is stipulated that impurity is an important assessment item, and the result is "none" to be regarded as a qualified product; the standard GB / T3780.12-2007 "Carbon Black Part 12: Inspection of Impurities" stipulates the equipment for the inspection of carbon black impurities, The process of sampling, analysis steps, presentation of results, etc. The brief process is: pour about 500 grams of ca...

AI Technical Summary

Problems solved by technology

[0004] 1. During the sieving process, a large amount of carbon black dust flies up, causing adverse harm to the environment and human health;

[0005] 2. It is time-consuming and labor-intensive for analysts to sieve with a brush. It is difficult to sieve some carbon black particles. After completing a few samples, the arm will feel sore, and the efficiency is low.
