Method and device for controlling liquid level of ore pulp pump pool in ore grinding classification

Abstract

The invention discloses a method and device for controlling the liquid level of an ore pulp pump pool in ore grinding classification. The method comprises the following steps of acquiring a first practical liquid level of the pump pool when the latest adjusting period starts and acquiring a second practical liquid level of the pump pool when the latest adjusting period finishes; calculating change values of the ore pulp volume in the latest adjusting period according to the ore pulp sizes formed by the first practical liquid level and the second liquid level in the pump pool respectively; calculating a first adjusting value of output flow based on the change values of the ore pulp volume and adjusting the current output flow according to the first adjusting value. By means of the technical scheme, the ore pulp flow output by the pump pool can be adjusted to meet the requirement for balancing the input and output of the ore pulp of the pump pool according to the first adjusting value obtained by calculating the change values of the ore pulp volume, so that stability of the height of the inner liquid face in the pump pool is more accurately maintained, and the effect of ore grinding classification is more stable.

Description

technical field [0001] The present application relates to the field of mineral processing process control, in particular to a method and device for controlling the liquid level of a pump pool during the grinding and grading process. Background technique [0002] In the production process of ore smelting, since the raw ore obtained from mining cannot meet the smelting requirements, it is necessary to process the raw ore first to obtain concentrates that meet the smelting requirements, and then use them in the smelting process. The beneficiation operation mainly includes crushing and screening of raw ore, grinding and grading, sorting, concentrate dehydration and other links. Among them, the grinding process is to crush the crushed ore to a suitable particle size, and provide the crushed minerals to the sorting process. During the grinding process, since the ore is crushed, the effective mineral components can be dissociated from the gangue, and different effective mineral co...

Problems solved by technology

[0005] The technical problem to be solved by this application is to provide a method and device for controlling the liquid level of the pump pool during the grinding and grading process, so as to solve the problem of real-time based on the actual liquid level of the pump pool at the current moment and the preset benchmark in the prior art. The difference between the liquid levels is used to adjust the output flow of the pump pool linearly related to the technical problem of inaccurate adjustment of the output flow of the pump pool
