Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
As Fig. 1 be kaolin ore-dressing technique flow chart, to realize the automation of ore-dressing practice, in each operational outfit all
There is provided monitoring alarm sensor, its capital equipment monitoring system is the hierarchical control using management level-key-course-mechanical floor
Network structure, using " simulating display screen+programmable controller（PLC）The multilevel monitor of+industrial computer ", be divided into management level,
Key-course and mechanical floor, management level mainly include the simulating display screen and industrial computer of central control room, and key-course is mainly
PLC controller, mechanical floor mainly include meter detection equipment, element and control executing agency.Management level, key-course and equipment
It is each independent between layer in addition to communication, without connection electrically, realize various functions independence.Therefore, it is even if a certain in system
Part is broken down, and will not influence the work of system other parts, so that whole system has high reliability, is really realized
Layered distribution type optimal control.
Simultaneous display factory owner wants equipment operation condition on the simulating display screen and industrial computer of central control room, if
It statistics have shown table, indicator light, such as be green instruction when equipment is run, be red when equipment stops；It is with slurry to whole ore deposit factory
The whole parameter such as material position, flow and valve opening of system carries out whole real time monitoring.Imitation screen is divided into two parts, shows respectively
Full plant process flow capital equipment operating status and stock mixing system automatic slurry-distributing situation.Technique ginseng with slurry can be completed on key-course
The functions such as several setting, measurement, display, control, alarm, record, inquiry and printing.Mechanical floor mainly includes each operational outfit
Operating status, such as rock feeder, belt conveyor, pulp grinder, log washer, eddy flow machine etc. are smash, and concentration basin, back pool etc. are respectively matched somebody with somebody
The operating status of stock tank.
Automatic slurry-distributing system of the present invention is the process with slurry applied in concentration basin 1 to collection stock tank 2 and blending pond 3, it sets
The standby and composition of instrument is as shown in Fig. 2, be described as follows：
Electric switching valve 4 is set respectively on the discharging pipeline of each concentration basin 1, controls being turned on and off for each collection charging of stock tank 2；
Branch 8 is set respectively on the main discharging pipeline of each concentration basin 1 and connects electric switching valve 4 and is used as feeding, can be wanted by technique
Ask and be sampled under control of the computer（Sample time, sample interval, feeding amount can be set in computer）, thus
The uniformity for bothering and realizing sample time for saving manual sampling ensures that the material sample fetched is representative, can preferably control
The stabilization of product quality, there is provided production management level；
An electric control valve 5 and a flowmeter 6 be set respectively on each collection 2 outlet conduit of stock tank, the aperture of valve 0~
100% is continuously adjustable, thus can accurately control pipeline starching flow, ensure with slurry to carry out in proportion；
In each collection stock tank 2 and blend the top of pond 3 ultrasonic level gage 7 be installed respectively, operating personnel can on computer screen and
Slurry position in real time is seen on big imitation screen, in addition starch position it is higher or lower when computer screen on and big imitation screen on can bullet
Go out warning message and send alarm, prompt operating personnel note that starch position it is excessive too low when control system will automatically cut off or
Open corresponding valve and carry out coordinated signals, slurry spilling can be avoided the occurrence of and stock tank position is too low also in the operation of discharge；
Electric switching valve 4 is set on the feed pipe in blending pond 3, is entered for the slurry in control pipeline.
To prevent line clogging, press is emptied in collection 2 peripheral hardware of stock tank, is dredged with air-blowing, once there is line clogging, air compressor machine
Begin to purge, the open and close of air compressor machine can be controlled with computer.
After being configured with the equipment instrument of the above, will be carried out to it is multiple collection 2 inflow and outflow slurry amounts of stock tank be controlled with
Adjust, can achieve the purpose that with slurry in proportion.When collection 2 quantity of stock tank is excessive, multiple collection stock tanks 2 can be divided into several subsystems
System, each stock tank of subsystem internal can first interworking, then produced by the proportioning starched between subsystem.
Operating personnel can carry out formula by keyboard or mouse on man-computer interface and select, and select formulation data
It can descend into PLC, automatic slurry-distributing is completed under the control of PLC system, detailed process is as follows：PLC system, which collects, to be installed on
The signal of corresponding pipeline flow meter 6, by the processing and computing of data, adjusts and is arranged on the motorized adjustment that collection stock tank 2 exports
The aperture of valve 5, load is accurately controlled through computing adjustment repeatedly at any time.
The slurries to multiple collection stock tanks 2 are needed by production, the slurries by formulation ratio into different demands then will proportioning
Good slurries, which are stored in, to be blended in pond 3, is automatically performed formula of size process.Control of the wet end furnish automatic control system in PLC
The lower ore pulp that can be accurately controlled is conveyed into blending pond 3 in the ratio being previously set, it is ensured that the stabilization of end product quality.It is controlled
Flow is as shown in Figure 3.
The above, is only present pre-ferred embodiments, is not intended to limit the scope of the present invention, therefore
Any subtle modifications, equivalent variations and modifications that every technical spirit according to the present invention makees above example, still fall within
Protection scope of the present invention.
