Should be appreciated that the present invention double take feed proportioning system be applicable to various occasion (such as: harbour, steel mill,
Power plant, grain distribution station and feed factory etc.) dispersion stacked or the material deposited (such as: coal, Ore, sand
Stone and grain etc.) carry out feeding, dispensing etc..Multiple (second is such as set up from taking from reclaimer by setting up
Material machine, the 3rd from reclaimer) can realize feeding and the dispensing of multiple different material, i.e. take dispensing more.
Hereinafter double the taking by harbour to the present invention double, is taken feed proportioning system as a example by coal blending transport and be described further.
In order to realize being mixed the most uniformly by two different kinds of coal, have employed Fig. 1
Shown double taking feed proportioning system, its capital equipment related to is: main reclaimer 21 and from reclaimer 22, skin
Band machine 31-36 and control device.Wherein, control device includes middle control host computer, the Your Majesty of main reclaimer
Position machine and from reclaimer from host computer.First, reclaimer by two different kinds of coal respectively from stockyard 11
Take out in 12, be delivered to transferring tower 41,42 by belt feeder 31,32 the most respectively, then by belt feeder
33-36 is transported to ship loader 51-54, finally sends into boats and ships.Main reclaimer and being believed by shared operation from reclaimer
Breath realizes collinear double take or the double coal stream being taken as industry of different line is pooled to Rendezvous Point simultaneously.
Fig. 2 is to utilize the present invention double to take feed proportioning system to carry out the Booting sequence figure of coal blending.At middle control host computer
After upper selected flow process, reclaimer host computer judges whether this reclaimer is main reclaimer, if main reclaimer,
First the most main reclaimer starts, if it is determined that this reclaimer is from reclaimer, does not then receive startup from reclaimer
Before signal, wait enabling signal.Main reclaimer enters next step after starting and judges whether heavy duty.Take if main
Material machine is not heavy duty, then be directly entered process flow operation.If main reclaimer is case of heavy load, at this moment need from
Reclaimer dispensing together, then override signal can be sent to from reclaimer after main reclaimer starts, from feeding
Machine enters trigger countdown after receiving main reclaimer override signal, and countdown brings into operation after terminating, enters
Enter process flow operation, thus realize the flow process of master and slave two reclaimer dispensings together.
Fig. 3 is to utilize the present invention couple to take feed proportioning system to carry out the operational flow diagram of coal blending.In process flow operation process
In, main reclaimer shows current accumulative feeding amount, instantaneous delivery and job scheduling percentage ratio, and according to working as
Front value carries out coal blending.And need time delay from information such as the instantaneous delivery of reclaimer, accumulative feeding amounts.Time delay
After accumulative feeding amount, instantaneous delivery and job scheduling percentage ratio, refer to master and slave take according to calculate
Material machine each coal flows to reach ship loader time difference, first main reclaimer is currently added up feeding amount, instantaneous delivery
Carry out storing rather than being transmitted directly to from reclaimer with the data of job scheduling percentage ratio, only work as the time
After difference, the data of storage are read by side by the storehouse treatment principle of first in first out, and show from reclaimer
On host computer, the speed that manipulation personnel adjust feeding in real time according to these data comes close to the chlorine adding ratio required.
Fig. 4 is to utilize the present invention couple to take feed proportioning system to carry out the stopping flow chart of coal blending.In stopping flow process,
Main reclaimer first completes feeding task, i.e. can be out of service after completing feeding task, when system judges main taking
In the case of material machine completes feeding task and has been zero load, transmission airborne signals is to from reclaimer, from feeding
Machine starts countdown, and countdown terminates, then also stop feeding from reclaimer, and i.e. all reclaimer is out of service,
Complete feeding task.
Utilize that the present invention is double to be taken feed proportioning system to carry out the concrete operations running of coal blending as follows:
First, in middle control host computer typing production information, i.e. choose corresponding pair and take dispensing flow process, including:
Coal information, deposit the target buttress position information of material, target feeding amount, target bin number, target binning amount and
Coal blending mode and chlorine adding ratio.
Then, sending the production information of above typing, corresponding two reclaimers all can receive institute's transmission information,
And show on host computer, hereafter will will be described in detail.
Middle control host computer flow monitoring include monitor coal blending relevant information, as the job information of reclaimer i.e. pile up neatly position,
Coal, target feeding amount, accumulative feeding amount, coal blending real-time scale, reclaimer job scheduling (main reclaimer
Do delay process).
Principal and subordinate's reclaimer judges: takes in flow process at different line pair, according to the encoder numerical value of two reclaimers, changes
Be counted as the reclaimer transferring tower distance to place belt, concrete, distance between reclaimer and transferring tower with
Reclaimer encoder numerical value is corresponding, therefore, it can converse reclaimer according to reclaimer encoder numerical value and arrives
The transferring tower distance of place belt, further according to the distance of each transferring tower to transferring tower 41, draws two reclaimers
To the distance of transferring tower 41, further according to the encoder numerical value of ship loader, it is converted into ship loader to 41 transferring towers
Distance, concrete, the distance between ship loader with transferring tower is corresponding with ship loader encoder numerical value, therefore,
Can converse ship loader to transferring tower distance according to ship loader encoder numerical value, finally summation draws each feeding
Machine is to the distance of ship loader.
Because reclaimer is different to the distance of ship loader, if two reclaimers start simultaneously at operation, distance is relatively
The coal taken of near reclaimer would first, through ship loader, and such coal blending quality is uneven.At the end of flow process,
If two reclaimers complete feeding task simultaneously, the part of coal that distant reclaimer is taken will be last
By ship loader, such coal blending quality is uneven, the finest, it is impossible to reach the requirement of client.So in order to
Ensure becoming more meticulous must be requested that the coal stream of two reclaimers crosses to Rendezvous Point and ties simultaneously simultaneously of coal blending
Bundle.
Distance according to reclaimer to ship loader compares and determines close together being set to from reclaimer, and distance
Farther out be set to main reclaimer, by being calculated the range difference of two reclaimers and known each belt feeder
The speed of service, draw two reclaimers to shipment machine-made egg-shaped or honey-comb coal briquets stream from getting the time difference of dress, and this time difference
It is exactly reclaimer with playing the error that the coal stream caused with the stopping time can not collect and terminate.So when main reclaimer is transported
During row, collect according to time difference delayed startup, such guarantee coal stream from reclaimer simultaneously.When main feeding
When machine completes feeding, completing feeding from reclaimer according to time difference time delay, such guarantee coal stream is with for the moment
Between terminate.
Owing to reclaimer driver operation level is inconsistent, it is impossible to ensure that reclaimer brings into operation with regard to feeding, in order to
Reducing temporal error, design is when flow startup, and main reclaimer is first begin to feeding, when belt conveyer scale wink
Shi Liuliang, more than 300 ton hour lasting more than 5s, determines that main reclaimer is in heavy service, and will weight
Information carrying number is sent automatically to from reclaimer, now starts feeding from reclaimer, reduces the most further by mistake
Difference.
After flow process brings into operation, will be according to flow and the progress tightly following main reclaimer from reclaimer, it is ensured that
The main reclaimer of reclaimer progress infinite approach, when reclaimer is near completion feeding task, and main reclaimer feeding is entered
Degree reaches 100% the most out of service, now airborne signals is sent to from reclaimer, receives letter from reclaimer
After number, start to stop feeding countdown, need in count down time, complete taking of self from reclaimer driver
Material task.Thus whole flow process terminates, coal blending program completes.
Delay process: in reclaimer operation process, reclaimer only shows that the instantaneous delivery of the other side is not anticipate
Justice, because needing to follow main reclaimer from reclaimer, if according to the main reclaimer of display from reclaimer
Instantaneous delivery carries out with reference to feeding, then the material that the same time is taken from reclaimer and main reclaimer can not be
Finally pool together, so this instantaneous delivery for just becoming nonsensical from reclaimer.In order to solve
This problem, it is simply that ensure to have used with main reclaimer flows match from the instantaneous delivery of reclaimer
State the time difference mentioned, by PLC program, instantaneous delivery each second of main reclaimer stored,
So time difference is within several seconds, just to store how many data, then the data stored at first are shown from reclaimer
Host computer on, carry out the most successively, the first spilling first stored.Now, reclaimer is with reference to this time difference
Instantaneous delivery after time delay carries out feeding, the coal so taken just and display main reclaimer instantaneous delivery
After pool together, reflect coal blending quality at that time.
Same reason, if entered according to current accumulative feeding amount and the reclaimer of main reclaimer from reclaimer
Degree is followed, then two reclaimers will complete feeding task simultaneously, and the most out of service, then
Coal stream can not terminate the same time, so main reclaimer shown from reclaimer adds up feeding amount and takes
Material machine progress also operation delay process, processing method is ibid.
Meanwhile, due to from reclaimer starting more late than main reclaimer, therefore, from the point of view of energy-conservation,
The time after the belt feeder delayed startup from reclaimer place, the time of time delay and time delay it is provided with in program
Unanimously.Thus avoid the long-time zero load from reclaimer place belt feeder.
By above method, four flow monitoring pages at middle control host computer add relevant information, convenient
Middle control dispatcher's overall management and monitoring coal blending performance, it is ensured that coal blending quality.
The job information of reclaimer includes: coal blending real-time scale, refers to double take in flow process, the coal of two reclaimers
The real-time scale of two kinds of coals at stream Rendezvous Point, as it is shown in figure 1, Rendezvous Point i.e. belt feeder 32 and belt feeder
35 (any one in belt feeder 33-36 can be selected as required, the most only as a example by belt feeder 35)
Joint；Accumulative feeding amount, the accumulative feeding amount of the most main reclaimer has done delay process, from reclaimer
The feeding amount of display current time.Reclaimer job scheduling shows and includes: add taking of reclaimer 21,22
Material progress, computational methods are that the cumulant of reclaimer is done divided by target feeding amount, the most main reclaimer progress
Delay process, when progress is more than 100%, can flash warning.When two reclaimer progresses of operation differ by more than
10%, also can point out warning.
The computational methods of real-time scale are: when reclaimer 21 is main reclaimer, and real-time scale is reclaimer
Instantaneous delivery after 21 time delays is than the instantaneous delivery of upper reclaimer 22, or real-time scale is that reclaimer 21 prolongs
Accumulative feeding amount time after is than the accumulative feeding amount of upper reclaimer 22；When reclaimer 21 is from reclaimer,
Real-time scale be the current instantaneous delivery of reclaimer 21 than the instantaneous delivery after the time delay of upper reclaimer 22, or
Real-time scale is that the current accumulative feeding amount of reclaimer 21 is than the accumulative feeding amount after the time delay of upper reclaimer 22.
Although instantaneous delivery has certain undulatory property, but from general trend body, can passing ratio size obtain
Go out and control the fine degree of coal blending.
Middle control dispatcher just can check real-time coal blending process according to the data shown by the upper page, when
During the feeding progress infinite approach of the reclaimer of two reclaimers, illustrate that coal blending quality is the highest.
Reclaimer is as the tool-type equipment of feeding, and its duty is to determine the important composition of coal blending quality
Part.Reclaimer become more meticulous now coal blending aspect urgent problem have following some:
(1) duty of the other side's reclaimer cannot be known during reclaimer coal blending operation, between big machine driver more
Real-time communication cannot be accomplished, it is difficult to ensure coal blending effect.
The big machine driver of (2) two coal blending operations cannot judge two by the positional information of two reclaimers
The relative feeding time difference of big machine, this has resulted in all can there is coal in two stages of flow startup and stopping
The situation that stream cannot mix so that coal blending quality declines.
(3) double when taking batch operation, owing to the maximum stream flow sum of two reclaimers is far longer than ground belt
Bearing capacity, this damage being possible to cause ground belt.
(4) during reclaimer operation, data that belt claims that what driver paid close attention to most is exactly, and these data are by many
The conversion of individual link and transmission, real-time is not enough, has certain time delay.
For with above Railway Project, start with in terms of upper display of reclaimer etc., it transformed.
1. according in control the job instruction provided, carry out logical operations with PLC program, it is judged that whether flow process is
Coal blending flow process；Judge the reclaimer numbering of two coal blendings；What so both sides driver just can be real-time
Solve handling situations and the progress of the other side's reclaimer, from the beginning of operation until the end of operation, be achieved that
Fine-grained management to whole coal blending process.
2., after being extracted data, double ship loader " leading " rank reclaimer farther out of adjusting the distance in blending process is taken
Requiring relatively low, he has only to ensure data according to the numerical value of upper " the target instantaneous delivery " calculated as far as possible
Feeding amount uniformly.And for distance ship loader close together " from " for rank reclaimer,
To be controlled is the most.Because the reclaiming process " leading " rank reclaimer has occurred and that, it is can not
Change, this just require " from " rank reclaimer to follow " leading " rank reclaimer always and carry out operation,
Coal blending quality is ensured with this.In order to greatest extent convenient " from " operation of rank reclaimer, carry for it
Data are the most intuitively supplied.
To " from " for reclaimer, the target instantaneous delivery of oneself reclaimer includes: the mesh of oneself reclaimer
Mark instantaneous delivery, draws according to the chlorine adding ratio of two reclaimers.No matter " lead " or " from " reclaimer
The workload needing to reach in oneself this flow process will be understood, to reach the highest work by these data
Industry efficiency.
The other side's reclaimer is that the work data of " leading " reclaimer includes: the work data of the other side's reclaimer, bag
(delay process by being taken now coal stream with oneself to include the other side's instantaneous delivery after the other side's reclaimer numbering, time delay
The instantaneous delivery of " leading " reclaimer converged), (delay process is for for the other side's actual feeding amount after time delay
" leading " reclaimer integrated flow through converging with oneself taken coal stream) and the target feeding amount etc. of the other side.
By these data, " from " reclaimer can be real-time the working condition grasping the other side's reclaimer, the most whole
Individual work flow, and by with the other side's time delay after instantaneous delivery ensure that ground belt occurs without overload condition,
Ensure that the safety of equipment.
The instantaneous delivery of this reclaimer includes with cumulative amount: the instantaneous delivery of this reclaimer and cumulative amount, helps
Driver understands the handling situations of oneself.
The job schedule of both sides' reclaimer includes with real-time chlorine adding ratio: the job schedule of both sides' reclaimer and reality
Time chlorine adding ratio, this has also been the major part of coal blending of becoming more meticulous, and " leads " rank feeding in this part
Machine can only see the job schedule of oneself, is only its offer and shows intuitively.And " from " rank takes
Material machine is necessary for paying close attention in real time the progress of both sides, in operation process, he to ensure as far as possible the progress on both sides without
Limiting close, the chlorine adding ratio of display is identical with the chlorine adding ratio of actual requirement in real time, if " from " rank feeding
Machine has ensured this state, finally can be realized as optimal coal blending effect.
3. in order to avoid the situation that coal stream cannot mix occurring the two of flow startup and stopping stages, at stream
Two stages of Cheng Qidong and stopping show for having carried out animation from rank reclaimer, and driver can pass through this
Display starts feeding and stops feeding, ensures that coal stream is in flow startup and two stages of stopping with this
Also can guarantee that good mixing." from " rank reclaimer can be according to the animation effect of coal stream flowing with during feeding
Between countdown control the time that feeding starts, at the end of feeding countdown, reclaimer just should be
Feeding starts, and what upper interface there is also " can be with feeding " flashes prompting.When system detects feeding
After machine feeding, flashing prompting will disappear.
When flow process stops taking, upper also having shuts down prompting accordingly.
In conjunction with Fig. 1-4, main reclaimer 21 with carry out coal blending operation, the most main reclaimer 21 from reclaimer 22
The material taken (can be selected in belt feeder 33-36 to belt feeder 35 as required by belt feeder 31 transport
Any one, the most only as a example by belt feeder 35), and the material taken from reclaimer 22 passes through belt feeder
32 transports are to belt feeder 35, then arrive ship loader 54 by belt feeder 35 transport.
After middle control chooses this flow process, PLC program calculates main reclaimer 21 automatically, from reclaimer 22, time
Between difference for 60s, start to input production information, production information includes: main reclaimer taken coal information, deposit
Put the buttress position information of material, target feeding amount, such as 3000 tons；From reclaimer 22 taken coal information,
Buttress position information, target feeding amount, such as 3000 tons；The storehouse number of boats and ships corresponding to ship loader 54；Coal blending side
Formula, such as " double take ".Target binning amount automatically generates, for example, according to the target feeding amount of principal and subordinate's reclaimer
6000 tons, if the target feeding amount of principal and subordinate's reclaimer is all 3000 tons, then chlorine adding ratio automatically generates,
For example, 1:1, selects the berth at boats and ships place, finally sends these production informations above-mentioned.
The data of middle control institute typing have been sent on two reclaimers of operation at once, and middle control starts Booting sequence,
First belt feeder 31 brings into operation, and main reclaimer 21 starts feeding, and middle control host computer display belt feeder 5 is opened
The countdown of beginning 60s, when main reclaimer 21 reach heavy duty require time, send self from trend from reclaimer 22
Override signal, starts feeding countdown 60s, from reclaimer 22 after 60s from the display of reclaimer 22 host computer
Starting feeding, stream acquired by the most main reclaimer 21 should be on belt feeder 31, but along with the fortune of belt feeder
OK, the material that main reclaimer 21 is taken by with the material taken from reclaimer 22 at belt feeder 35 and belt feeder 32
Intersection collect the same time.
In operation process, main reclaimer 21 can check the job scheduling percentage ratio from reclaimer 22 at any time,
The job scheduling before main reclaimer 60s can be viewed, when from reclaimer 22 feeding progress from reclaimer 22
