Definitions
- the invention relates to a method for controlling a refiner for treating fibrous material based at least in part on its idle power, the refiner having a housing in which a first treatment tool and a second treatment tool are arranged, the treatment tools are each attached to a base plate, a rotationally symmetrical one Have shape, are arranged coaxially to each other, rotate relative to each other about a common axis and delimit a treatment gap radially flowed through by the fibrous material, the gap width of which can be changed via an axial displacement of at least one base plate of a treatment tool.
- Devices of the above Kind z. B. used to improve the quality of pulp, TMP or fiber, which was obtained from waste paper.
- pulp fibers i.e. Grinding fresh cellulose and / or waste paper fibers in order to be able to achieve the desired properties, in particular with regard to strength, porosity, formation and surface, in the fibrous web produced therefrom.
- the grinding surfaces are formed by exchangeable grinding sets screwed to the corresponding base plate due to the relatively fast wear.
- the grinding sets must be adapted as best as possible to the fiber material to be treated, also in order to prevent excessive wear of the sets.
- an optimal use of the available grinding surface is sought.
- the object of the invention is to enable safe and efficient operation of these refiners with the simplest possible means.
- the object was achieved by repeatedly measuring at least one value of the idle power in the presence of fibrous material or water during the opening and / or closing of the treatment gap over the service life of at least one treatment tool, storing it in a memory of the controller and alone or in connection with other values are evaluated by the control.
- the idle power which relates to the throughput quantity of fiber per unit time and is usually between 40 and 250, in particular between 40 and 150 kWh, is very important.
- At least one value of the idle power measured when opening and / or closing the treatment gap should be used directly or indirectly, for example by means of average values or by linking to other parameter values, to control the overall performance and thus also the specific performance of the refiner.
- the total power consumed is made up of the idle power and the specific power of the refiner relevant for the desired treatment intensity.
- the aim is to determine the idle power as accurately as possible, it may be advantageous to measure the idle power with a constant gap width.
- the value of the idle power is measured several times, preferably at certain time intervals, for example a few seconds, and stored in the memory.
- a substantial increase in the measurement accuracy can be achieved by at least a first average value being formed from at least some of the idle power values measured when the treatment gap is opened and / or closed and stored in the memory as the current idle power.
- a second average value should be formed from at least some of the idle power values measured when opening and / or closing the treatment gap and stored in the memory as the current idle power instead of the first average value, although values are not taken into account that deviate more than 20% from the corresponding first average.
- the treatment gap In the event that the treatment gap remains closed for a predetermined maximum operating time of, for example, 24 hours, it should be opened and closed again in the interest of a value for the idle power that is as up to date as possible to determine the idle power.
- the essential parameters such as pressure, flow rate and consistency of the fiber suspension should be in the normal operating range when determining the idle power.
- one treatment tool should rotate and the other should not, with at least one treatment tool being axially displaceable.
- the treatment tool and base plate can also be made in one piece.
- the consistency of the fibrous material being between 2 and 6, preferably between 3.5 and 4.5%.
- the fibrous material can in particular also be TMP, high-yield pulp, MDF fibrous material, wood chips or the like. Trade substances.
- the paper pulp 1 is according to Figure 1 pressed directly into the central, ie radially inner area of the refiner set, which is formed by the two treatment tools 3, 4.
- While one treatment tool 3 is stationary and thus designed as a stator, the other treatment tool 4 is rotatably mounted in the housing 2 of the refiner.
- the treatment tools 3, 4 each have a rotationally symmetrical shape, whereby the two annular grinding surfaces are arranged parallel to one another and the gap distance between them can be adjusted via an axial displacement, usually of the rotating treatment tool 3.
- the rotating grinding surface is moved in the direction of rotation by a shaft rotatably mounted in the housing 2.
- This shaft is driven by a drive also present in the housing 2.
- the fiber suspension 1 to be ground passes through an inlet through the center into the grinding gap 6 between the grinding surfaces of the two treatment tools 3, 4.
- the fiber suspension 1 passes the interacting grinding surfaces radially outward and leaves the adjoining annular space through a drain.
- Both grinding surfaces are each formed by a plurality of grinding plates, each of which extends over a peripheral segment of the corresponding grinding surface.
- the grinding plates result in a continuous grinding surface.
- the grinding plates and thus also the grinding surfaces are generally formed by a multiplicity of essentially radially running grinding strips 9 and grooves in between.
- the treatment tools 3, 4 are fastened on corresponding base plates 7, 8.
- the treatment gap 6 can run not only perpendicularly but, as in the case of cone refiners, also inclined to the axis of rotation 5.
- Figure 2 illustrates the change in the real idle power P Lreal of the refiner over the operating time t, which changes with increasing operating time t and thus also increasing wear of the treatment tools 3, 4 is largely continuously reduced.
- the total power P G which is fed to the refiner is composed of the idle power P Lreal and the specific power Ps responsible for the treatment intensity of the fibrous material 1, ie the grinding power.
- the idle power P L stored for the control of the refiner becomes over the operating time t updated many times, ie adjusted to the real idle power P Lreal .
- the value of the idle power P L stored for the control of the refiner is generally updated in the presence of fiber 1 during the opening and / or closing of the treatment gap 6 under normal operating parameters such as pressure, flow and material density.
- the idle power P L of the refiner is measured several times and at certain time intervals of approximately 2 s and stored in the memory as values of the idle power P L.
- a first average value is then formed from the values of the idle power P L measured when the treatment gap 6 is opened or closed.
- a second average value is then formed and stored from these measured values of the idle power P L , whereby values which deviate more than 20% from the corresponding first average value are not taken into account.
- a common, second average value for the control is formed from the two.
- the control system opens and closes the treatment gap 6 specifically to determine the current idle power P L. It can thus be prevented that the real idle power P Lreal deviates too much from the idle power P L stored in the control of the refiner.
- the idle power P L is measured when the treatment gap 6 is closed and stored in the memory as the starting value for the control.
- the knowledge of the at least approximately real idle power P L has an influence not only on the specific power but also on the control of the gap adjustment in the treatment tools 3, 4.
