Specific embodiment
The present invention is described in further detail below with reference to embodiment, embodiments of the present invention are not limited thereto.
Fig. 1~3 are preferred embodiments of the invention, if Fig. 1 is the flow chart of kaolin ore-dressing technique, to realize ore-dressing practice
Automation, in each running equipment all be provided with monitoring alarm sensor, capital equipment monitoring system be using management
The hierarchical control network structure of layer-control layer-mechanical floor, using " simulating display screen+programmable controller (PLC)+industry is counted
The multilevel monitor of calculation machine ", is divided into management level, control layer and mechanical floor, and management level mainly include the simulative display of central control room
Screen and industrial computer, control layer are mainly PLC controller, and mechanical floor mainly includes that meter detection equipment, element and control are held
Row mechanism.It is respectively independent between management level, control layer and mechanical floor in addition to communication, without connection electrically, realize various function
It can be independent.Therefore, even if certain a part in system breaks down, the work of system other parts will not be influenced, to make
Whole system has high reliability, really realizes 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 entire mine 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.The achievable technique ginseng with slurry on control layer
The functions such as several setting, measurement, display, control, alarm, record, inquiry and printing.Mechanical floor mainly includes each running equipment
Operating status, such as rock feeder, belt conveyor, smash pulp grinder, log washer, eddy flow machine etc. and concentration basin, back pool etc. are respectively matched
The operating status of stock tank.
Monitoring system is connected by the present invention with stock mixing system, realizes automatic slurry-distributing, automatic slurry-distributing system is to apply be concentrated
Pond 1 is to collection stock tank 2 and blends the process with slurry in pond 3, and the composition of equipment and instrument is as shown in Fig. 2, be described as follows:
Be respectively set electric switching valve 4 on the discharge nozzle road of each concentration basin 1, control unlatching that each collection stock tank 2 is fed or
It closes;Branch 8 is respectively set on the main discharge nozzle road of each concentration basin 1 and connects electric switching valve 4 and is used as feeding, it can be by work
Skill requires to be sampled (sample time, sample interval, feeding amount can be arranged in computer) under control of the computer, this
Sample just saves the trouble of manual sampling and realizes that the consistency of sample time guarantees that the material sample fetched is representative, can be preferably
The stabilization for controlling product quality, provides production management level;
An electric control valve 5 and a flowmeter 6, the aperture of valve is respectively set on each 2 outlet conduit of collection stock tank
It is continuously adjustable 0~100%, the flow of pipeline starching can accurately be thus controlled, guarantee is with slurry to be carried out in proportion;
In each collection stock tank 2 and 3 top of pond installation ultrasonic level gage 7 respectively is blended, operator can be in computer screen
Slurry position in real time is seen on upper and big imitation screen, in addition when slurry position is higher or lower on computer screen and on big imitation screen
It will pop up warning message and issue alarm, prompt operator note that control system will be cut automatically when slurry position is excessively high too low
Break or open corresponding valve and carry out linkage control, can avoid slurry spilling occur 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 controlling the slurry in 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
It begins to purge, the open and close of air compressor machine can be controlled with computer.
After equipment instrument more than being configured with, it can be realized by monitoring system and multiple 2 inflow and outflows of collection stock tank are starched
Amount is controlled and is adjusted, and can be achieved 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, each stock tank of subsystem internal can first interworking, then produced by the proportion starched between subsystem.
Operator can carry out formula by keyboard or mouse on man-computer interface and select, and select formulation data
Can descend into PLC, complete automatic slurry-distributing under the control of PLC system, detailed process is as follows: PLC system, which collects, to be mounted on
The signal of corresponding pipeline flow meter 6 adjusts and the motorized adjustment that collection stock tank 2 exports is arranged in by the processing and operation of data
The aperture of valve 5 accurately controls load through operation adjustment repeatedly at any time.
The slurries to multiple collection stock tanks 2 are needed by production, it, then will proportion by formulation ratio at the slurries of different demands
Good slurries, which are stored in, to be blended in pond 3, and formula of size process is automatically performed.Control of the wet end furnish automatic control system in PLC
It is lower can be accurately controlled ore pulp in the ratio being previously set be conveyed into blend pond 3, it is ensured that the stabilization of end product quality.It is controlled
Process 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 to the above embodiments according to the technical essence of the invention, still fall within
