Definitions
- the present invention relates to a system for monitoring the condition of a screen basket of a sorter for treating a pulp suspension.
- the aim of sorting is the separation of interfering solid constituents from pulp suspensions.
- the separation is carried out by screening according to the particle characteristics of size, shape and deformability.
- the sorting is an important separation process in the processing of waste paper.
- different sorters are used. Thereby u.a. so-called basket sorter used with a screen basket arranged in a housing.
- the technical data of the screen basket are taken on an end ring of the screen basket. Since the screen basket is arranged in the housing of the respective sorter, the reading of these specifications is relatively expensive. In addition, the state of wear of the strainer basket remains uncertain, especially as there is no curriculum vitae or history for the baskets and no operating data is available.
- the invention has for its object to provide a system for monitoring the state of a screen basket of a sorter for the treatment of a pulp suspension, in which the aforementioned problems are eliminated.
- a faster error-free readout of the screen basket relating to technical data is to be ensured and a more comprehensive monitoring of the state of the screen basket from the outside is made possible.
- the system according to the invention for monitoring the condition of a screen basket of a sorter for treating a pulp suspension comprises a wireless identification unit assigned to the screen basket arranged in a sorter housing and an external, in particular mobile reading unit for non-contact reading of technical data relating to the screen basket from the identification unit and for production a connection to another external database containing the sorter data.
- the technical data relating to the screen basket can be transmitted from the outside, in a cable-free and contact-free manner. be read from outside the sorter's housing quickly and reliably.
- further data related to the sorter may be accessed in an external database, thereby enabling a more comprehensive monitoring of the state of the screen basket.
- a corresponding screen basket information can be read into the external database when installing the screen basket.
- the further data relating to the sorter can, for example, be collected via a control system of the factory in which the sorter is installed and supplied to the external database. Sales staff and customers can each be given a mobile reading unit, in particular, so that the outside of the screen basket, i. from outside the case.
- a respective reading unit comprises a display for displaying further data relating to the sorter retrieved from the external database.
- Such an RFID chip in particular represents a transponder which contains the technical data relating to the screen basket.
- the transponder is a radio communication device that receives incoming signals and automatically answers.
- the coupling can be done by magnetic field generated by the reading unit short range or by high-frequency radio waves. This not only allows data to be transferred, but also the transponder can be supplied with energy. For larger ranges, for example, an active RFID chip with its own power supply is conceivable.
- the reading device may contain software which controls the actual reading process for reading out the technical data relating to the screen basket from the identification unit or the RFID chip.
- the reading unit may comprise an RFID middleware with an interface to the external database.
- the identification unit preferably comprises at least one RFID chip assigned to the screen basket of the sorter.
- the identification unit comprises both an RFID chip assigned to the screen basket of the sorter and an RFID chip assigned to the housing of the sorter, wherein the RFID chip assigned to the screen basket is connected to the housing via a software coupling associated RFID chip coupled and the housing associated with the RFID chip can be read via the reading unit.
- the reading unit can establish a connection between the RFID chip assigned to the housing and the external database.
- the connection between the RFID chip and the external database is not affected in this case by the usually metallic case of the sorter.
- the RFID chip assigned to the screen basket of the sorter can also be read out directly via the reading unit.
- the RFID chip assigned to the screen basket of the sorter is preferably arranged in the region of the opening of the sorter which can be closed by a cover.
- the lid of the sorter can then be removed, whereupon the RFID chip associated with the screen basket of the sorter can be read out directly by means of the reading unit.
- the RFID chip associated with the screen basket of the sorter can, in particular, be arranged on or in an end ring of the screen basket.
- the RFID chip associated with the screen basket of the sorter is arranged on or in one of the openings of the screen basket which can be closed by a lid of the sorter.
- the screen basket of the sorter associated RFID chip is preferably arranged on the opening of the sorter facing the top of the end ring.
- the RFID chip assigned to the screen basket of the sorter is arranged on the radial inner side of the end ring, thus further improving the accessibility of the RFID chip for coupling the reading unit.
- the RFID chip assigned to the screen basket of the sorter is accommodated sunk in the end ring.
- the sunk in the end ring of the screen basket housed RFID chip is preferably encapsulated with plastic or preferably Teflon.
- Such a cover is convenient because the strainer basket is typically recycled, i. especially chromed and electropolished.
- the other data relating to the sorter are preferably stored together with the technical data relating to the screen basket in the external database.
- the assignment to the other data relating to the sorter can thus be established in the external database.
- further data relating to the sorter via the reading unit include production data of the screen basket, cv basket cv data, sorter operation data, wear data of the screen basket and / or the like.
- the manufacturing data of the screen basket may contain, for example, data relating to the construction, the material, the size, etc. of the screen basket.
- the cuvette's cv data may include, for example, data regarding reprocessing of the screen basket, storage times, etc.
- the operating data of the sorter include, for example, the running time, the flow / pressure at the inlet / outlet of the sorter, the rotational speed etc. This information can be obtained, for example, via the machine control of the sorter.
- the system according to the invention comprises data processing means for determining the baskets' throughput, the speed of rotation of the strainer basket, the energy balance between the input and the outputs of the sorter and / or the like on the basis of the service life of previous screen baskets To determine the degree of wear of the screen basket and thus the next change date for the screen basket.
- FIG. 1 in a purely schematic representation of an exemplary embodiment of a system 10 according to the invention for monitoring the state of a screen basket 12 of a sorter for the treatment of a pulp suspension.
- the system 10 includes according to FIG. 2 a wireless identification unit 14 associated with a screen basket 12 arranged in a housing 24 of the sorter and an external, in particular mobile reading unit 16 for non-contact reading of technical data 18 relating to the screen basket 12 from the identification unit 14 and for establishing a connection with a further data relating to the sorter containing external database 20.
- the reading unit 16 may include a display for displaying further data related to the sorter retrieved from the external database.
- the identification unit 14 may comprise at least one RFID chip. In this case, it comprises at least one RFID chip associated with the screen basket 12 of the sorter.
