Abstract

The invention relates to a crude potassium repulping washing control system and control method, and a crude potassium repulping washing device. The crude potassium repulping washing control system includes a saline ion concentration sensor in a one-grade washing chamber, a saline ion concentration sensor in a second-grade washing chamber, and a controller, wherein the saline ion concentration sensor in the one-grade washing chamber is used for acquiring first saline ion concentration signals in the one-grade washing chamber and sending the first saline ion concentration signals to the controller; the saline ion concentration sensor in the second-grade washing chamber is used for acquiring second saline ion concentration signals in the second-grade washing chamber and sending the second saline ion concentration signals to the controller; and the controller is used for receiving the first saline ion concentration signals, comparing the first saline ion concentration signals with the preset first saline ion concentration signals, receiving the second saline ion concentration signals, comparing the second saline ion concentration signals with the preset second saline ion concentrationsignals, and sending a valve opening signal and a fine potassium mother liquor pump power adjusting signal to a fresh water inlet valve and a fine potassium mother liquor pump according to the comparison result respectively.

Description

technical field [0001] The invention relates to the field of crude potassium washing automation, in particular to a crude potassium repulp washing control system, a control method, and a crude potassium repulp washing device. Background technique [0002] At present, in the production process of potassium fertilizer and other salts, Yantian carnallite can produce qualified potassium chloride products through technological processes such as reverse flotation, decomposition and crystallization, repulping, washing and drying. Among them, crude potassium repulp washing is an important process to control product quality, and the optimization of its washing efficiency has always been a subject of continuous exploration by scientific and technological workers. [0003] CN107352561A discloses a crude potassium repulp washing device, which includes a cylinder and a stirring rod. The cylinder is provided with a double-layer annular partition, and the cylinder is divided into clarifica...
