Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1 is refer to, Fig. 1 is the flow chart in a kind of embodiment provided by the present invention.
In a kind of embodiment provided by the present invention, feeding control method mainly includes two steps, wherein step
S1 is：The current material amount in crusher chamber is detected, and step S2 is：If the easy accounting of current material amount and crusher chamber is less than pre-
If value, then improve delivery rate；If the volume accounting of current material amount and crusher chamber is more than preset value, delivery rate is reduced.
Wherein, in step sl, main contents thing is the current material amount of detection crusher chamber, that is, is detected in disintegrating machine 2
Crusher chamber, the inventory in operation, volume or weight that typically can be by detecting material etc..The inventory is to change at any time
, one side batcher 1 is constantly toward supplementing material in crusher chamber, while crusher chamber again constantly crushes material.
In step s 2, main contents are judge the volume accounting of current material amount and crusher chamber, if current material amount and
The volume accounting of crusher chamber is less than preset value, then improves delivery rate；If the volume accounting of current material amount and crusher chamber is more than
Preset value, then reduce delivery rate.The preset value can artificially be set according to actual conditions, may generally be 1:1, i.e. current material amount
When equal with the volume of crusher chamber (or when being completely fed), volume accounting is 100%, and now operating mode is optimal, and volume accounting is more than
During the preset value, delivery rate is improved, when volume accounting is less than the preset value, delivery rate is reduced, finally causes volume accounting
The convergence preset value.
In this way, when detecting that the inventory in crusher chamber is less, delivery rate is improved so that entered in the unit interval
Inventory increase in crusher chamber, so that the inventory in crusher chamber gradually increases, is finally reached full feed working condition,
Take full advantage of the power of crusher chamber；And when detecting that the inventory in crusher chamber is more, reduce delivery rate so that unit
The inventory entered in time in crusher chamber is reduced, so that the inventory in crusher chamber gradually decreases, is finally reached work(
In rate allowed band, overload damage phenomenon is avoided the occurrence of.
When detecting the current material amount in crusher chamber, especially by the height of materials in detection crusher chamber in the present embodiment
And complete detection.The relatively regular shapes such as crusher chamber is generally pylindrical, spheroid or rectangle in view of disintegrating machine 2, and directly examine
The weight or volume of survey current material amount is more difficult, therefore to simplify the detection method of current material amount, only need to detect crusher chamber
Interior height of materials, so as to replace being worth the height of materials value in crusher chamber as its inventory (weight or volume).
Further, when the height of materials value in by crusher chamber replaces its inventory, judge current material amount with
During the volume accounting of crusher chamber, you can the height ratio by calculating height of materials in crusher chamber and crusher chamber is completed volume and accounted for
Than calculating.Because the shape of crusher chamber is relatively regular, therefore pass through height of materials and the ratio calculation volume accounting of crusher chamber height
It is more accurate.Such as if the height of materials in crusher chamber is 1m, and the height of crusher chamber is 2m, then current material amount
Volume accounting with crusher chamber is 50%.Certainly, though crusher chamber it is in irregular shape, can similarly pass through height of materials
With the ratio calculation volume accounting of crusher chamber height, preset value corresponding to test of many times determination is only needed simultaneously.
And in a kind of preferred embodiment of the height of materials on detection crusher chamber, specifically can be by detecting material
Surface is the distance between to preset height, then the difference calculated between preset height value and testing result is completed.In view of material
When being contained in crusher chamber, and the height of direct measurement material is not easy to, therefore can determine that it is high by way of measuring indirectly
Degree.Wherein, preset height is a standard value, its height value, it is known that and surface of material to the distance between preset height detection
After going out, you can preset height value is subtracted into testing result, the difference drawn is height of materials.Such as preset height 3m, break
Broken chamber is highly 2m, and now the surface of current material to the distance between preset height is 1.2m, then between 3m and 1.2m
Difference be 1.8m, i.e., now height of materials is 1.8m.It should be noted that preset height, crusher chamber height with ground or
Some reference plane is defined.
Further, it is contemplated that volume, the size of lump are different, therefore the surface of material in crusher chamber and non-flat
Face, but rough irregular face.In this way, after the distance between surface of material and preset height is detected, can obtain more
Individual testing result (quantity number depend on the precision of detection), the value of these testing results is also different, but generally with certain value
Centered on fluctuate.In this way, each detection data can be averaging processing first, and tied the average value of acquisition as detection
Fruit, that is, the equivalent plane height value of surface of material carries out mathematic interpolation as testing result and preset height value.So calculate
Height of materials value in the crusher chamber obtained afterwards is more accurate and reliable.
In addition, the current material amount in crusher chamber no matter is detected in which way, can be according to current after the completion of detection
The volume accounting of inventory and crusher chamber controls the broken speed of crusher chamber, so that both match each other.It is it has been mentioned hereinbefore that broken
The current material amount of broken intracavitary, in dynamic equilibrium, material, another aspect disintegrating machine 2 is continuously replenished in one side batcher 1
Body is constantly broken, spent material.In this way, in order that disintegrating machine 2 can adapt to current material amount, avoided simultaneously using power as far as possible
Energy dissipation, realize and save emission reduction, the broken speed of crusher chamber is controlled according to the volume accounting of current material amount and crusher chamber, is made
It must crush that speed is suitable with the delivery rate of batcher 1, so as to ensure the inventory in crusher chamber and the power phase of disintegrating machine 2
When.
The present invention also provides a kind of feed control system, mainly includes detection module and control module, wherein, detection module
Mainly for detection of the current material amount in crusher chamber, and control module is mainly used in the volume in current material amount and crusher chamber
Accounting improves delivery rate when being less than preset value, and is dropped when the volume accounting of current material amount and crusher chamber is more than preset value
Low delivery rate.Specifically, detection module is connected with control module signal, detection module feeds back the current material amount detected
To control module, control module is contrasted the volume accounting of current material amount and crusher chamber with preset value, when the former is less than
During the latter, control frequency converter to carry out speed governing to the motor of batcher 1 by pid algorithm using PLC degree etc., accelerate motor and turn
Speed accelerates the purpose of the delivery rate of batcher 1 so as to reach, and vice versa.In this way, the control to delivery rate forms closed loop control
System, and pid algorithm is used, its precision is higher, and control is gentler.
In a kind of preferred embodiment on detection module, the detection module can be for detecting in crusher chamber
The distance measuring sensor 4 of height of materials, so as to replace the volume or weight of material by detecting the height of material.Specifically, the survey
It can be arranged on away from sensor 4 on the inwall of crusher chamber, pass through the height of the mode direct measurement material such as opto-electronic conversion.Or such as
Foregoing teachings, the distance measuring sensor 4 can be arranged on to the higher position of disintegrating machine 2, then using oneself height as preset height, passed through
Measure itself and arrive the distance of surface of material, then preset height value is subtracted into measurement distance value, the height of material is used as using difference.
Specifically, the distance measuring sensor 4 can be ultrasonic sensor, it is higher apart from accuracy of detection and reliability.Certainly,
Distance measuring sensor 4 can also be laser range sensor, proximity switch or travel switch etc..
