Slurry Automatic Filtration Sampling Device

Abstract

The invention discloses an automatic filtering and sampling device of ore pulp and belongs to the field of solid-liquid separation devices. The device is characterized in that an ore pulp outlet of a sampling pump is communicated with the inner part of a filtering tank; one end of a liquid collection pipeline is arranged in the filtering tank and is communicated with a filter liquid outlet of the filtering tank, and the other end of the liquid collection pipeline stretches out of the filtering tank; a primary discharging pipeline with a first automatic control valve and a primary filter liquid discharging pipeline with a second automatic control valve are arranged on the liquid collection pipeline stretching out of the filtering tank, and the primary filter liquid discharging pipeline is connected with a sample trough; the sample trough is provided with a liquid level meter, a turbidity meter, a secondary discharging pipeline and a secondary filter liquid discharging pipeline, the secondary discharging pipeline is provided with a third automatic control valve, and the secondary filter liquid discharging pipeline is provided with a fourth automatic control valve and is connected with a conveying bucket; the conveying bucket is provided with a filter liquid conveying device and a filter liquid outlet end; a controller is electrically connected with each automatic control valve to open and close each automatic control valve. The automatic filtering and sampling device can be used for automatically sampling and filtering the ore pulp and is suitable for the sampling of on-line ore pulp ion concentration analysis instruments applied to wet metallurgy and ore separation processes.

Description

technical field [0001] The invention belongs to the field of solid-liquid separation equipment, in particular to a device for automatically filtering ore pulp into filtrate that can be directly used for chemical analysis. Background technique [0002] In the field of hydrometallurgy and mineral processing, due to the needs of process production, it is usually necessary to measure and analyze the ionic components in the pulp; the determination and analysis of the ionic components need to separate the solid and liquid of the pulp to obtain a clarified solution, and then analyze the clarified solution. Currently, the commonly used method for obtaining the clarified solution is: laboratory personnel take a sample of the ore pulp, filter it with filter paper in the laboratory, and analyze it after obtaining the clarified solution. The method of laboratory analysis has a large lag and cannot guide the production process in time, so it is necessary to realize the online analysis of...
