Abstract
The utility model discloses a kind of flotation column tank level control system, comprise potentiometric sensor, PID controller and magnetic valve three part, wherein potentiometric sensor is positioned at flotation column body, and potentiometric sensor is connected with PID controller, and PID controller is connected with magnetic valve.This system utilizes the difference of the resistivity of flotation froth and ore pulp, the height change of liquid level is converted into the signal of telecommunication, is transferred to PID controller, and PID controller is passed through the aperture of Controlling solenoid valve and then controlled mineral pulp level.The utility model utilizes the signal of telecommunication to measure the change of liquid level, reacts sensitiveer, controls more accurate, can ensure the stability of mineral pulp level.
Description
Technical field
The utility model relates to the tank level control system of ore dressing field, particularly relates to a kind of tank level control system of flotation column.
Background technology
Column flotation is a kind of beneficiation method efficiently.In column flotation process, in cylinder, the stability of mineral pulp level has vital effect for improving flotation effect and improving the quality of products.Traditional flotation column tank level control system is generally reflected by liquid level by mechanical signal, often there is certain hysteresis quality in actual use, can not be real-time by the altitude feedback of liquid level to automatic control system, thus be difficult to ensure the stability of mineral pulp level.
Summary of the invention
The purpose of this utility model is to provide a kind of flotation column tank level control system of simple and efficient, and this control system is quick on the draw, and control effects is good.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: flotation column tank level control system, comprise potentiometric sensor, PID controller and magnetic valve three part, wherein potentiometric sensor is positioned at flotation column body, potentiometric sensor is connected with PID controller, and PID controller is connected with magnetic valve.
This system utilizes the difference of the resistivity of flotation froth and ore pulp, the height change of liquid level is converted into the signal of telecommunication, is transferred to PID controller, and PID controller is passed through the aperture of Controlling solenoid valve and then controlled mineral pulp level.
The beneficial effects of the utility model are: utilize the signal of telecommunication to measure the change of liquid level, react sensitiveer, control more accurate, can ensure the stability of mineral pulp level.
Accompanying drawing explanation
Accompanying drawing 1 is scheme of installation of the present utility model;
Accompanying drawing 2 is operation principle schematic diagram of the present utility model.
Drawing illustrates: 1. potentiometric sensor 2.PID controller 3. magnetic valve 4. flotation column A. sets level parameter value B. actual liquid level parameter value.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but be not restriction the utility model.
With reference to accompanying drawing 1, the utility model comprises potentiometric sensor 1, PID controller 2 and magnetic valve 3 three part, and wherein potentiometric sensor 1 is positioned at flotation column 4 column body, and potentiometric sensor 1 is connected with PID controller 2, and PID controller 2 is connected with magnetic valve 3.
Because the resistivity of flotation froth and ore pulp there are differences, when mineral pulp level changes, the potential value that potentiometric sensor 1 measures also changes according to certain functional relation.According to test requirements document, a setting level parameter value A is set in advance in potentiometric sensor 1.With reference to accompanying drawing 2, the real-time tele-communication of mensuration number is transferred to PID controller 2 by potentiometric sensor 1, by the calculating of the computing unit of PID controller 2 inside, be corresponding actual liquid level parameter value B by transform electrical signals, and compare with setting level parameter value A, if B>A, then illustrate that ore pulp actual liquid level has exceeded setting liquid level, Controlling solenoid valve 3 is opened large aperture by PID controller 2, strengthens the underflow discharge amount of ore pulp; On the contrary, if B<A, then illustrate that ore pulp actual liquid level is lower than setting liquid level, Controlling solenoid valve 3 reduces or closes aperture by PID controller 2, reduces the underflow discharge amount of ore pulp.This process is back and forth carried out, until the actual liquid level of ore pulp is equal with setting liquid level.
