Abstract
A kind of flotation cell concentrate foam scrapes the control method of output, testing agency is provided with near flotation cell liquid level, corresponding height of liquid level signal is exported according to flotation cell liquid level height is corresponding, this signal is delivered to frequency converter and is changed the frequency of scraping board motor after signal switching mechanism conversion, it is slow that final scraper plate is scraped when liquid level height, that scrapes when liquid level is low is fast, and flotation cell is remained, and a stable concentrate foam scrapes output.
Description
Art
The present invention relates to the control method that a kind of flotation cell concentrate foam scrapes output, particularly immediately accurately can control the method that flotation cell concentrate foam scrapes output.
Background technology
At present; the control that flotation cell concentrate foam scrapes output is generally indirectly control by controlling height of liquid level; the control major part of height of liquid level is all manual adjustment valve or the height being controlled liquid level by a series of very complicated control system through the aperture of pneumatic electro by-pass valve control; the change changing to liquid level due to valve has a time delay; add that the amount of flotation pulp inevitably often can change to some extent; so the liquid level of flotation cell is always unstable, the instability of flotation cell liquid level causes foam to scrape output instability naturally.Scraping the problem of output instability in order to solve flotation cell concentrate foam, the invention provides the control method that a kind of flotation cell concentrate foam scrapes output.
Summary of the invention
Scraping the control problem of output in order to solve flotation cell concentrate foam, the invention provides a kind of simple, durable, being easy to the control method of the flotation cell concentrate foam that existing flotation cell is transformed being scraped to output.
The technical solution used in the present invention is: a kind of flotation cell concentrate foam scrapes the control method of output, comprising: level detection mechanism, signal switching mechanism, frequency converter and scrape board motor.Testing agency is provided with near flotation cell liquid level, corresponding height of liquid level signal is exported according to flotation cell liquid level height is corresponding, this signal is delivered to frequency converter and is changed the frequency of scraping board motor after signal switching mechanism conversion, it is slow that final scraper plate is scraped when liquid level height, that scrapes when liquid level is low is fast, and flotation cell is remained, and a stable concentrate foam scrapes output.
Compared with prior art, the invention has the beneficial effects as follows:
One, stable concentrate foam can be kept under various regimes to scrape output, can concentrate yield be reduced, improve concentrate grade.
Two, manpower is saved.Because whole control procedure is automatic, need not often control concentrate foam and scrape output by manual adjustment liquid level.
Three, transformation is simple.Owing to just increasing level detection mechanism, signal switching mechanism and frequency converter on existing flotation cell, so it is very simple to transform existing flotation cell.
Accompanying drawing explanation
Accompanying drawing is schematic diagram of the present invention.In figure 1, level detection mechanism.2, signal switching mechanism.3, frequency converter.4, board motor is scraped.5, scraper plate.6, concentrate foam.7, flotation cell.
Concrete implementation:
Below in conjunction with accompanying drawing, the present invention is described further.
Example 1: level detection mechanism is ball float, signal switching mechanism is travel switch, and ball float is connected by flexible cord with travel switch.Flotation cell liquid level height changes ball float position, the change of ball float height drives travel switch to send respective switch signal to frequency converter in order to change the output frequency of frequency converter, the final change rotating speed of scraping board motor scrapes output to what change concentrate foam, during liquid level height, frequency is low, scraper plate motor speed is slow, when liquid level is low, frequency is high, and scraper plate motor speed is fast, the scraping output and can keep a stable state always of concentrate foam.
Example 2: level detection mechanism is stainless steel probe, signal switching mechanism is liquid level relay, probe detects flotation cell liquid level height and changes the output state of liquid level relay, liquid level relay outputs signal frequency converter in order to change the output frequency of frequency converter, the final change rotating speed of scraping board motor scrapes output to what change concentrate foam, during liquid level height, frequency is low, scraper plate motor speed is slow, when liquid level is low, frequency is high, scraper plate motor speed is fast, the scraping output and can keep a stable state always of concentrate foam.
Example 3: level detection mechanism is ultrasonic level gage, ultrasonic level gage is by launching ultrasound examination flotation cell liquid level height, signal switching mechanism in ultrasonic level gage outputs a control signal to frequency converter in order to change the output frequency of frequency converter according to flotation cell liquid level height, the final change rotating speed of scraping board motor scrapes output to what change concentrate foam, during liquid level height, frequency is low, scraper plate motor speed is slow, when liquid level is low, frequency is high, scraper plate motor speed is fast, the scraping output and can keep a stable state always of concentrate foam.
Example 4: level detection mechanism is the probe of fluid level transmitter, signal switching mechanism in fluid level transmitter outputs a control signal to frequency converter in order to change the output frequency of frequency converter according to flotation cell liquid level height, the final change rotating speed of scraping board motor scrapes output to what change concentrate foam, during liquid level height, frequency is low, scraper plate motor speed is slow, when liquid level is low, frequency is high, and scraper plate motor speed is fast, the scraping output and can keep a stable state always of concentrate foam.
