Abstract

The invention discloses a pressure control type ore pulp multi-site synchronous sampling device and method, and relates to the technical field of ore pulp sampling of mineral processing subjects. Thesampling device is composed of a plurality of sampling unit systems in parallel, and each system comprises an independent air pressure control system, an anti-suction pulp tank, a sample kettle, an ore pulp control valve, a pulp suction pipe and an accurate sampling rod control system. According to the sampling device and method, the multi-unit combination system is controlled, so that multi-sitesynchronous sampling can be accurately carried out on ore pulp in large-scale preparation equipment, and reliable test analysis samples are provided for parameter design and optimization of the preparation equipment. The sampling device has the advantages of being simple in structure, simple and convenient to operate, flexible in sampling, and meanwhile, capable of ensuring the stability, the accuracy and the representativeness of the sampling process.

Description

technical field [0001] The invention belongs to the technical field of ore pulp sampling in the discipline of mineral processing, and in particular relates to a pressure-controlling multi-point synchronous sampling device and method for ore pulp applied to large-scale mineral processing equipment. Background technique [0002] As the country advocates large-scale, centralized and efficient processing of natural mineral resources, it poses more severe challenges to the development and optimization of mineral separation equipment technology. The design and optimization of a new type of mineral processing equipment requires a large number of repeated theoretical derivation calculations and experimental analysis and verification. From small-scale experimental beneficiation equipment to industrial (semi-industrial) equipment, in order to realize its design concept and performance, it is not only necessary to follow the principle of geometric similarity of equipment, but also to m...
