S8) mixed feeding cumulant in the unit of account time, adjusts the more respective parameters of bucket wheel reclaimer: according to letter
The parameter of breath and more bucket wheel reclaimers, mixed feeding cumulant in the unit of account time, more bucket wheel reclaimers of adjustment are respectively
Parameter, unit time 10min.
Specifically, referring to Fig. 3, using two bucket wheel reclaimers, respectively R1 bucket wheel reclaimer in the embodiment
With R2 bucket wheel reclaimer, stacker, belt feeder and transferring tower have also been matched, has constituted its mixed production line, two buckets
The material point of reclaimer is taken turns at the TH2 transferring tower in the middle part of 10# belt feeder, constitutes entire mixed work flow.
It is understood that bucket wheel reclaimer control system, bucket wheel machine feeding data monitoring monitoring system, driving it is hydraulic
It stands system, optical fiber and interchanger communication system and middle control Communication processing system constitutes the control device of mixed work flow.
Referring to Fig. 4, be this method mixture operation pile shape schematic diagram, according to two bucket wheel reclaimer basic equipment information,
Such as bucket wheel diameter, walking precision, determine basic reclaiming technology.R1 bucket wheel reclaimer and R2 bucket wheel reclaimer mixture feeding behaviour
Making technique is stepping revolution layering feeding (fan-shaped stepping layering feeding), and bucket wheel is placed on material heap top layer setting, rotation is passed through
Turn control feeding, often get to rotating range, the distance of one section of walking mechanism fine motion setting starts to reversely rotate feeding, until taking
Then unbroken layer returns again to beginning setting, cantilever declines a feeding height, changes layer operation, so recycles.I.e. bucket wheel takes
Material machine steps on corresponding charge level, and operation revolution carries out feeding to material buttress by different level.Feeding section in small ladder-like, layer with
Width is 7-8 meters (a bucket wheel diameter) between layer, is highly 4 meters (half of bucket wheel diameter).It is dynamic using walking step-by-step system
Vehicle, step distance should not be too large, and prevent flow excessive or bored bucket occurs, step motion control is advisable in 0.3 to 0.6 meter of distance, wide
When degree reaches 7-8 meters, carry out changing layer.
Two bucket wheel reclaimer feeding strict control stability of flow, there can be no phenomenons fluctuated (to give target value
± 500t/h), it causes mixed uneven.Feeding flow is not below 500t/h simultaneously, and flow is not easy to control, mixed efficiency mistake
Low phenomenon.When feeding, due to mixing in the case where the factors such as layer height, bucket wheel diameter, step distance and bucket wheel revolving speed determine
The instantaneous flow of raw material is size-controlled in rotational speed, that is to say, that rotational speed is unstable or not easy to control, feeding wink
Shi Liuliang will unstable bad control, it is unstable to eventually lead to mix ratio, and mixture is uneven.So in the embodiment, bucket
Reclaimer rotational speed size is taken turns using multi-mode control (PID, HIM, handle), realizes the control of rotational speed multi-mode.Its
In, handle controls labor intensity maximum, and discharge stability control is poor, generally selects handle big in irregular material buttress feeding
Small control;In operation interface input speed size in HMI control, strength reduction, stability increases, but is not changing
In the case where inputting size, in stock ground, most inner side and outermost flow have significant change trend, need in revolution action process
In, fine tuning interface inputs size;PID control is automatically adjusted according to weighing belt flow, oil pump Main motor current whole process speed, is used
System working pressure matches rotational speed and adjusts bucket wheel revolving speed as monitoring, keeps instantaneous flow more stable.
In order to reliably control rotational speed, rotational speed size control model can be increased in station and select knob, led to
The interface modification HMI and PLC program are crossed, realizes and selects " handle control ", " interface input control ", " PID control " mould in station
Formula.When knob is at " interface input control ", rotary handle only controls gyratory directions, and handle tilt angle no longer controls revolution
Velocity magnitude, rotational speed size need to input at the interface HIM, can directly input, can also put button " increase " or " subtract
It is small " it is adjusted as unit of 1Hz;
When selection " PID control ", rotational speed is controlled according to weighing belt flow, oil pump Main motor current whole process speed
Automatic adjustment, while using system working pressure as monitoring, matching rotational speed adjusts bucket wheel revolving speed;When knob is in " handle control
When system ", rotary handle controls rotational speed size and Orientation (retaining original function).Three kinds of control models can also be in HMI circle
Switched on face, more suitable control model can choose for different pile shape feedings, in this way since may be implemented to revolution
Effective reliable control of speed, to keep instantaneous flow more stable.Realize that two bucket wheel machine data are total by middle control communication
It enjoys, then show that two equipment materials reach the time difference of TH2 tower by sequential operation, to realize synchronously control.Pass through
PLC program design realizes traveling little progress encoder and time control, improves feeding step distance precision.
Weighing belt data on flows, oil pump Main motor current, the system work of more bucket wheel machines are realized by control device interaction
Make pressure and location information intercommunication is shared, while more bucket wheel reclaimer walking position data of transmission are read by control device
It realizes that position is shared, multiple devices material is calculated and reaches the time difference of point, to realize synchronously control;Adjustment row
It walks little progress coder parameters and travel time is controlled, improve more bucket wheel machine feeding step distance precision;According to information
With the parameter of more bucket wheel reclaimers, the instantaneous flow mixture waveform graph of more bucket wheel reclaimers is made, and records mixture
Quality;According to the parameter of information and Duo Tai bucket wheel reclaimer, mixed feeding cumulant in the unit of account time adjusts more buckets
The respective parameter of reclaimer is taken turns, the unit time is 10min in the present embodiment.
In conclusion the present invention has the advantages that sharing and struggling against from data information intercommunication between more bucket wheel reclaimers
The control of turbine rotational speed multi-mode obtains the comparison of cumulative amount tendency chart, the comparison of instantaneous flow waveform diagram, row in the unit time
Many-sided information such as location information interface display is walked, feeding driver operation intensity is reduced, record feeding mixture process data, mentions
High flow capacity stability promotes mixed quality and efficiency.
As known by the technical knowledge, the present invention can pass through the implementation of other essence without departing from its spirit or essential feature
Scheme is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.
All changes within the scope of the invention or within the scope equivalent to the present invention are included in the invention.
