Grinding and crushing device with quick feeding and automatic discharging and blowing functions

Abstract

The invention discloses a grinding and crushing device with quick feeding and automatic discharging and blowing functions. The grinding and crushing device comprises a feeding system, a grinding system, a discharging system and an automatic blowing system. In use, solid particle samples enter the grinding system from the feeding system and are ground and crushed, then the discharging system is started, fine powder samples are collected, the automatic blowing system is started, and powder residues are blown out through airflow supplied by an air supply. The process that the solid coarse samples such as coal, ores and medicine are quickly fed, ground, crushed, discharged and collected, and the sample residues are blown out quickly and automatically is achieved, the coarse samples can be fed for grinding and the powder obtained through crushing can be taken out without repeatedly opening or closing a tank cover in the whole process, meanwhile, the problems that as for traditional methods, materials are cleaned manually with brushes, and consequently broken filaments mix in the materials to cause pollution and raising dust causes harm to operators and pollutes the environment are solved, the feeding time and the discharging time can be shortened, the labor intensity of the operators can be relieved, the working environment can be improved, and the samples can be crushed fully automatically through additional installation of a simple electronic control element.

Description

technical field [0001] The invention relates to a grinding and crushing device, in particular to a fast feeding, automatic feeding and purging grinding device. Background technique [0002] In the coal, metallurgy, and pharmaceutical industries, it is often necessary to crush solid particles into powder before sample analysis, leaching and extraction. For example, for coal sample analysis, the sample is crushed to a particle size of less than 0.2mm. At present, the sample preparation and crushing in these fields generally adopts a vibrating grinder composed of a grinding ring, a grinding rod and a grinding bowl. When using, the operator needs to open the bowl cover to feed materials. After grinding and crushing, open the bowl cover again, take out the grinding ring and grinding rod in the grinding bowl, dump the material bowl to take out most of the material samples, and then use a brush to remove the grinding ring, The residual material sample on the grinding rod and grind...

Problems solved by technology

When using, the operator needs to open the bowl cover to feed materials. After grinding and crushing, open the bowl cover again, take out the grinding ring and grinding rod in the grinding bowl, dump the material bowl to take out most of the material samples, and then use a brush to remove the grinding ring, The residual material sample on the grinding rod and grinding bowl is collected by brushing. The operation process needs to be opened and closed repeatedly. The brush filaments are often brought in to pollute the samples, and the number of samples that can be ground and prepared at a time is also small, at most only 3
