Abstract

The invention provides a control system and method for a thickening machine. The control system for the thickening machine comprises the thickening machine, a flocculant delivery pump connected with the thickening machine, a first controller, an underflow pump and a second controller, wherein the controller is connected with the flocculant delivery pump, and the first controller is used to dynamically adjust current operating frequency of the flocculant delivery pump according to a flow rate and density of feeding ore slurry of the thickening machine; and the second controller is connected with the underflow pump, and the second controller is used to dynamically adjust current operating frequency of the underflow pump according to a flow rate and density of the feeding ore slurry of the thickening machine, a density of ore slurry at an outlet of the underflow pump and a bottom pressure value of the thickening machine. According to the control system and method provided by the invention, automatic control of the operating frequency of the flocculant delivery pump and the underflow pump during operation of the thickening machine can be realized, so that the thickening machine runs stably, and the automatic control effect of the thickening machine is improved.

Description

technical field [0001] The invention relates to the technical field of thickeners, in particular to a thickener control system and method. Background technique [0002] In related technologies, the thickener is generally controlled, and the thickener is manually controlled on site, or the flocculant delivery pump and the underflow pump are operated at a set frequency. When the operating conditions change greatly, the operating frequency parameters cannot be adjusted in time, which may cause the thickener to run unstable and the control effect is not ideal. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the object of the present invention is to propose a thickener control system, which can automatically control the operating frequency of the flocculant delivery pump and the underflow pump during the operation of the thickener, so that the thickener can...
