Description
The present invention relates to a kind of equipment for processing fiber to control based in part on the idle capacity of equipment
Method, wherein the equipment have shell, the first handling implement and second processing tool, institute are disposed in the shell
It states handling implement to be separately fixed on substrate, the shape with rotational symmetry is mutually coaxially arranged, opposite around common axis
The processing gap radially to be flowed by fiber is rotated and limits, the gap width in the processing gap can be by handling work
The axial movement of at least one substrate of tool is changed.
Due to fiber in processing possessed relatively high consistency, although the handling implement that can be moved relative to each other is not
It is in contact, but is mutually passed through with smaller spacing, but realize high-intensitive mechanical treatment in this equipment (refiner).
Occurs obvious action power herein.
Quality improvement of the equipment of the above-mentioned type for example applied to paper pulp, TMP pulp or the fiber by being obtained in waste paper.
For a long time it is known that paper pulp fiber namely fresh stock and/or old paper fiber should be ground, so as to
Thus desired characteristic can especially be reached in manufactured fibrous cloth width in terms of intensity, porosity, molding and surface.
In the refiner used thus, abradant surface based on it is comparatively faster abrasion and by it is replaceable, with corresponding base
The grinding accessory that plate is threadedly coupled is constituted.
In order to reach desired fiber properties, especially lapping degree, grinding accessory must as far as possible well with to handle
Fiber match, and with the excessive wear to avoid accessory.
In addition, in order to fiber treatment improved efficiency and promote the optimum utilization to available abradant surface.
By document US 3 602 833 A1 of 2,004,/01 12 997 A1 and DE 2 939 587 A1 and DE it is known that
Equipment investment disposably measures or calculates idle capacity and is subject to use as the basis for apparatus control before using.
Anyway, the efficiency of processing is all reduced in the case where gap is excessive.In the case where gap is too small again shape
The risk contacted at excessively high current drain and handling implement.
Technical problem to be solved by the present invention lies in using measure as simple as possible realize the safer of the equipment and
Efficient operation.
The technical problem so solves according to the present invention, that is, in the service life of at least one handling implement, is locating
Reason gap is opened wide and/or the down periods distinguish at least one multiple for measuring idle capacity there are fiber or water and count
The numerical value is stored into the memory of controller and individually or jointly other numerical value and is assessed by controller by value.
At this it is clear that the idle capacity of equipment changes in the operation time-continuing process of handling implement.With processing work
The ever-increasing abrasion of the shape exterior feature of tool, idle capacity is opposite to be drastically declined.
However when controlling or regulating equipment, idle capacity is extremely important, the fiber treatment of the idle capacity and unit time
Amount is related and is usually located at 40 to 250, especially 40 between 150kWh.
It therefore should be straight by the numerical value of at least one idle capacity measured when handling gap and opening wide and/or close
Connect or indirectly, for example by average value or with the control of other parameters value being associated with for general power, and also and then be used for
The control of the exclusive power of equipment.
The idle capacity of equipment should be usually determined when coming into operation so far, and is stored for controlling or using thus
Preset numerical value.
Total consumed power is made of the idle capacity and the exclusive power important to the processing intensity sought of equipment.
The runing time and handling implement previously passed through due to each handling implement increased abrasion, the especially processing therewith
The abrasion of the shape exterior feature of tool reduces the current idle capacity of the equipment.Therefore overall power consumption can correspondingly be reduced.
However it is constant due to being considered as idle capacity in control/adjusting so far, then it will lead to for required processing
The general power of intensity consumption is set excessively high, high 20% even greater numerical value.
In addition, will lead to when handling space closure power based on the idle capacity reduced due to abrasion excessively high and phase
It is calibrated after must carrying out with answering, or even results in the damage of handling implement.
If seeking accurately to determine idle capacity as far as possible, it is advantageous to real in the case where gap width is constant
Apply the measurement of idle capacity.
On the other hand it can be realized within the shorter time in the case where gap width changes more to idle capacity
Measurement.
In order to improve the accuracy of measurement, it typically is advantageous to, when handling gap and opening wide and/or close to idle capacity
Numerical value respectively repeatedly, preferably at definite intervals, such as several seconds is measured and stored in memory.
Significantly improving for measurement accuracy may be implemented herein, mode is, at least by processing gap open wide and/or
A part of the numerical value of the idle capacity measured when closing constitutes at least one first average value and as current idle running function
Rate stores in memory.
However when processing gap is only slightly open, the biggish measurement error for idle capacity still may cause.
In order to exclude the numerical value when averaging, it should the idle capacity at least by being measured when handling gap and opening wide and/or close
A part of numerical value constitute the second average value and replace the first average value to be stored in memory as current idle capacity
In, however wherein, the numerical value with corresponding first mean deviation greater than 20% is all ignored.
It being provided in view of the numerical value for current idle capacity related frequency, old numerical value should be ignored, thus according to
The numerical value of idle capacitys and/or its first average value and/or its second average value that one or more finally measures are realized to setting
Standby control.
The case where (such as 24 hours) remain turned-off in scheduled maximum runing time for processing gap, between the processing
Gap is opened wide and again by extraly in order to determine idle capacity to obtain the numerical value as instant as possible of idle capacity
It closes.
In order to the initial value for being used for controller be stored in memory after the replacement of at least one handling implement,
Advantageously, measuring by maintenance personnel and inputting idle capacity, or pass through controller itself when handling space closure
Measure idle capacity.
The flow and material of main parameter, such as pressure, fibrous suspension should usually be made when determining idle capacity
Density is in normal range of operation.
In order to obtain the simple structure of equipment, it should it rotates a handling implement and does not rotate another handling implement,
Wherein, at least one rotary tool shaft is to movably supporting.In specific implementation, handling implement and substrate can be with
It designs one-piece.
Particularly advantageously, it applies according to the method for the present invention in refiner, especially LC (low consistency) refiner, wherein
The material density of fiber is between 2 to 6, preferably 3.5 to 4.5%.
The fiber can especially be related to TMP, high yield paper pulp (Hochausbeute-Zellstoff), MDF fiber, by wood
Clast made of material or unclassified stores.
The present invention should be illustrated in more detail by embodiment below.In the accompanying drawings:
Fig. 1: showing the schematic cross-section across refiner, and
Fig. 2: the true idle capacity P of t at any time is shownLrealVariation and general power PGAdjustment.
Paper-making fibre 1 is pressed directly into center namely the radial inner region of refiner matching piece, the essence according to Fig. 1
Machine matching piece is ground to be made up of two handling implements 3,4.
One handling implement 3 is fixed and is thus configured to stator, and another handling implement 4 rotatably supports
In the shell 2 of refiner.
Handling implement 3,4 is respectively provided with the shape of rotational symmetry, wherein two circular abradant surfaces cloth in parallel to each other
It sets, and the gap spacing between abradant surface can be arranged by the axial movement of the handling implement 3 usually rotated.
The abradant surface of rotation can be moved by the axis rotatably supported along direction of rotation herein.The axis passes through same
The driver that sample is present in shell 2 is driven.
Fibrous suspension 1 to be ground here shown in pass through entrance in embodiment and pass through middle part and reach two processing works
Milling gap 6 between the abradant surface of tool 3,4.
Fibrous suspension 1 pass through coefficient abradant surface radially flow, and by outlet leave it is adjacent
Annular chamber.
Two abradant surfaces pass through multiple abrasive sheets respectively and constitute, and the abrasive sheet is respectively in the circumferential area of corresponding abradant surface
Extend in section.
Abrasive sheet forms to arranged in succession continuous abradant surface along circumferential direction.
Abrasive sheet and in turn abradant surface are usually by multiple generally radially extending lapping sticks 9 and between lapping stick
Slot is constituted.
Device known per se has been not shown, and is axially moveable the handling implement 4 of rotation using the device and surveys
Measure the degree of the axial movement.Irrotational handling implement 3 does not change its axial position.
In addition, handling implement 3,4 is fixed on corresponding substrate 7,8.It is different from embodiment shown here, handle gap
6 can not only extend vertically and obliquely in the case where conical refiner relative to rotation axis 5.
Fig. 2 shows the true idle capacity P of refinerLrealVariation in duration of operation t, the true idle running function
Rate with ever-increasing duration of operation t and and then it is substantially continuous with the ever-increasing abrasion of handling implement 3,4
Ground reduces.
Here, the general power P of input processing equipmentGBy idle capacity PLrealWith for the processing intensity of fiber 1, Ye Jiyan
Grind the exclusive power P of powerSComposition.
In order to avoid exclusive power PSIt is apparently higher than in the operation duration of handling implement 3,4 and to be sought for fiber 1
Power needed for handling intensity, to control the stored idle capacity P of processing equipmentLIt is repeatedly updated in long t at runtime, namely
Compensation is true idle capacity PLreal。
Exclusive power P in this t long at runtime shown in Fig. 2SMean general power P in the case where constantGSimultaneously and
With the idle capacity P of storageLIn identical range and with this with true idle capacity PLrealClosely similar mode reduces.
The update of the numerical value of the idle capacity PL stored for control processing equipment is generally there are fiber 1
It is opened wide in processing gap 6 and/or the down periods is under normal operating parameter, such as normal pressure, flow and material density
It completes.
For this purpose, when handling gap and opening wide and/or close to the idle capacity P of processing equipmentLRespectively repeatedly and with about
Time interval for the determination of 2s repeatedly measures, and as idle capacity PLNumerical value storage in memory.
Then, the idle capacity P by being measured when handling gap 6 and opening wide or closeLNumerical value constitute the first average value.By
Idle capacity PLThe numerical value that measures then constitute the second average value and stored, wherein it is big with corresponding first mean deviation
Numerical value in 20% is ignored.
If calculating second for second average value of unlimited calculating in processing gap 6, and for the closing in processing gap
Average value is then made of common second average value for controller the two.
By using idle capacity PLThe second average value as the basis for controlling processing equipment, can exclude bigger
Measurement error.The case where worried is, with constantly close to the processing gap 6 closed, power consumption increases and obvious
Higher than idle capacity PL。
That important for the control of equipment is only idle capacity PLOr corresponding average value finally store as a result,
That is, it is possible to cover/delete the older numerical value in the memory of controller.
If processing gap 6 is not opened wide within such as longest long period for 24 hours, controller is exclusively for determination
Current idle capacity PLAnd it is open and close to implement opening for processing gap 6.It is so avoidable to be, true idle capacity PLreal
Excessively clearly deviate from the idle capacity P being stored in the controller of processing equipmentL。
It comes into operation or trial operation or replacement handling implement 3,4 or when its matching piece in processing equipment, idle capacity PL
It is measured when handling gap 6 and closing and is stored in memory as the initial value for controller.
To at least approximate true idle capacity PLAcquisition exclusive power is not only influenced in handling implement 3,4, but also
Have an effect on the control to gap adjustment.
Can additionally preset minimum idle running power P be lower thanLWhen be inferred in handling implement 3,4 it is corresponding higher
Abrasion, this just needs to replace handling implement.
