Thickener is concentration and the clarifying equipment of a kind of continuous work, be mainly used in ore-dressing technique the concentration of tailing water and
Clarification.Thickener generally uses center to be fed when working, slurry be admitted to thickener center by barrel, then flow into sedimentation
Area.It mainly utilizes sedimentation theory by the solid particles sediment in ore pulp to bottom of pond, and sand setting is discharged from underflow opening, clarification
Water is discharged from overflow weir, to achieve the purpose that separation of solid and liquid.
Slurry usually directly feeds thickener and gives barrel top, and the rake of thickener is located at concentration motor spindle, and being used for will
The material scraper of concentration motor spindle is deposited on to the underflow opening of bottom centre, and is walked with pumping, primary water is discharged from overflow port.But
Current thickener there is a problem of very big because that cannot automatically control revolving speed, it may be assumed that when thickener rake revolving speed is high, power consumption
Height, and flow field can be upset；When rake revolving speed is low, power consumption is low, but cannot blow precipitating material off in time, and discharge is slow, causes to press
Rake accident.
Utility model content
The purpose of this utility model is the real-time monitoring in order to realize thickener rake revolving speed, avoids rake revolving speed too low
When, cannot in time discharge and cause to press rake accident, while when preventing rake revolving speed excessively high, rake stirring upsets flow field and makes particle
It can not settle.
In order to achieve the above object, the utility model provides, and a kind of thickener rake based on feeding coal and feedstock concentrations turns
The real-time monitoring system of speed, specific technical solution are as follows:
Thickener rake revolving speed real-time monitoring system based on feeding coal and feedstock concentrations characterized by comprising
Flowmeter and densimeter: being mounted on thickener feeding pipe, for measuring the flow and concentration of ore pulp, obtains ore pulp
Real-time data on flows and concentration data；
Programmable controller PLC: for acquiring mineral slurry flux data and concentration numbers that flowmeter and densimeter measure it is believed that
Number, obtained data are passed through the thickener rake revolving speed control algolithm set and are handled, thickener rake is calculated
Suitable rotational speed, and the control signal of thickener revolving speed is transferred to frequency converter；
Frequency converter: being connected with the rotary electric machine of rake in thickener, and after frequency converter receives control signal, control turns
The revolving speed of dynamic motor, and then achieve the purpose that control thickener rake revolving speed；
Host computer: for showing the real-time concentration of ore pulp and the real-time revolving speed of flow and thickener rake.
The thickener rake revolving speed real-time monitoring system based on feeding coal and feedstock concentrations, which is characterized in that institute
The flowmeter and densimeter stated can monitor the flow and solid concentration of thickener pan feeding ore pulp, to obtain thickener pan feeding
Amount of solid.
The thickener rake revolving speed real-time monitoring system based on feeding coal and feedstock concentrations, which is characterized in that institute
The PLC and frequency converter stated can be with the revolving speed of real-time control thickener target.
The utility model has the beneficial effects that:
The utility model carrys out the revolving speed of real-time control thickener rake with a kind of completely new control system, prevents pressure from harrowing
The generation of accident and particle can not settle the generation of accident.
Detailed description of the invention
Fig. 1 is the thickener rake revolving speed real-time monitoring system provided by the utility model based on feeding coal and feedstock concentrations
Schematic diagram.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing, so that the utility model is excellent
Point and feature can be easier to be readily appreciated by one skilled in the art, to make to the protection scope of the utility model apparent bright
True defines.
As shown in Figure 1, the real-time monitoring system of the thickener rake revolving speed of the utility model, comprising:
Flowmeter and densimeter: being mounted on thickener feeding pipe, can monitor the flow of thickener pan feeding ore pulp and consolidate
Bulk concentration obtains the real-time data on flows of ore pulp and concentration data, to obtain the amount of solid of thickener pan feeding.
Programmable controller PLC: for acquiring mineral slurry flux data and concentration numbers that flowmeter and densimeter measure it is believed that
Number, obtained data are passed through the thickener rake revolving speed control algolithm set and are handled, thickener rake is calculated
Suitable rotational speed, and the control signal of thickener revolving speed is transferred to frequency converter；
Frequency converter: being connected with the rotary electric machine of rake in thickener, after frequency converter receives control signal from PLC,
It can be with the revolving speed of real-time control thickener target；
Host computer: for showing the real-time concentration of ore pulp and the real-time revolving speed of flow and thickener rake.
A kind of control method of the real-time monitoring system using above-mentioned thickener rake revolving speed, specifically: according to described
The real-time data on flows of the ore pulp that densimeter and flowmeter monitor and concentration data, give PLC technology data signal transmission
Device PLC, programmable controller PLC calculate the amount of solid in ore pulp and are calculated by thickener rake revolving speed control algolithm
Suitable thickener rake revolving speed, and pass through the revolving speed of frequency converter real-time control thickener rake, it may be assumed that the solid of thickener pan feeding
Amount then accelerates greatly rake revolving speed, and amount of solid is few then to slow down rake revolving speed, and the revolving speed of thickener rake is controlled with this, prevents pressure from harrowing
Accident and particle can not settle the generation of accident.
Further, function used in thickener rake revolving speed control algolithm are as follows:Wherein,
υ is thickener rake revolving speed, and Q is the flow of ore pulp, and C is the solid concentration of ore pulp, and S is the settling area of thickener, and a is tailing
The influence coefficient of property.
The utility model has the advantage of generation and particles that pressure rake accident is prevented with a kind of completely new control system
The generation that accident can not be settled, due to current thickener there is a problem of because revolving speed cannot be automatically controlled it is very big: work as concentration
When machine rake revolving speed is high, power consumption is high, and can upset flow field；When rake revolving speed is low, power consumption is low, but cannot blow precipitating off in time
Material, discharge is slow, causes to press rake accident.The utility model calculates pan feeding by monitoring thickener feeding coal and feedstock concentrations
Amount of solid, then the suitable rotational speed of thickener rake is calculated by thickener rake revolving speed control algolithm, and then realize to concentration
The real-time control of machine rake revolving speed to prevent the generation of pressure rake accident and improves the working efficiency of thickener with this.
Not limited to this, any change or replacement expected without creative work should all be covered in the utility model
Protection scope within.Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
