Definitions

  • the invention relates to a classifier according to the preamble of patent claim 1, with a housing which forms a classifying chamber, in which one or more ventilation floors are arranged and in which classifying gas is flowed through in order to separate fine material from coarse material, a classifying gas inlet and a Visible material inlet opens into the viewing area and a fine goods outlet and a coarse material outlet emerge from the viewing area.
  • Such classifiers which are also referred to as statically operating, serve to separate bulk materials into two fractions with different particle size distributions.
  • the fractions are separated in the classifying chamber in which the classifying gas flows through the classifying gas in the transverse direction from the classifying material inlet in the direction of the coarse material outlet. Smaller particles are entrained by the sight gas flow and transported to the fine material outlet, while larger particles are discharged through the coarse material outlet.
  • the ventilation floors of a static classifier are aligned more or less transversely to the direction of movement of the material to be viewed, with a step-like arrangement of the ventilation floors being often provided ( DE 43 37 215 A1 ).
  • an essentially flat ventilation floor is provided with a plurality of ventilation slots.
  • the ventilation floor can be composed of a large number of individually interchangeable slotted plates.
  • the visible material falling in the visual space hits the ventilation floor or floors and the visual gas flows through there.
  • the impact of the material to be sighted on the ventilation floor (s) can, on the one hand, increase the length of time of the material to be placed in the viewing space.
  • the impact of the visible material on the ventilation floors causes deagglomeration of frequently present visual material agglomerates, the so-called Schülpen. Both improve the sighting effect of a static classifier.
  • Static classifiers are often combined with dynamic classifiers, with the static classifiers regularly being upstream as a coarse classifier and serving as a fine classifier.
  • Dynamic classifiers are based on one Separation of two fractions of the material to be classified, which differ in terms of particle size distribution, by means of a rotating driven basket.
  • a combination of a static classifier as a coarse classifier and a dynamic classifier as a fine classifier in a circulation grinding plant for cement clinker is, for example, from the DE 43 37215 A1 known.
  • the static sifter is connected downstream of a roller press and is subjected to comparatively coarse and a large number of slugs.
  • the coarse material separated in the static classifier is returned to the roller press, while the fine material is fed to a tube mill by means of the classifying gas stream, in which it is further comminuted.
  • the material to be viewed is then fed from the tube mill to the dynamic classifier, in which the material to be separated is separated into medium and fine material.
  • the very fine material is then removed as finished product from the classifying gas in a separator, while the medium fine material is returned to the tube mill.
  • the circulation grinding plant according to the DE 43 37 215 A1 the static sifter and the dynamic sifter are separated both spatially and functionally by the interposition of the tube mill.
  • the static classifier thus essentially serves to avoid the supply of excessively large particles or flakes to the tube mill.
  • FIG DE 10 2011 055 762 A1 A device for classifying bulk material, in which a static classifier and a dynamic classifier are connected in series in a common housing and thus flowed through by the same classifying gas flow, is shown in FIG DE 10 2011 055 762 A1 known.
  • the upstream connection of the static classifier essentially serves to avoid exposure of the rotatingly driven and comparatively sensitive viewing basket of the dynamic classifier to large particles and flakes.
  • a dynamic classifier in the housing of which a bypass channel is integrated which bypasses the classifying chamber and via which a part of the dust-air mixture supplied via an inlet can be guided in the classifying room to avoid classifying. This should make it possible to specifically influence the particle sizes in the finished product leaving the dynamic classifier.
  • the CA 2 400 859 A1 discloses a device according to the preamble of claim 1, for separating a harvest mixture consisting of grain, chaff and grasses into its components, the device combining a sifter with a cyclone separator.
  • the US 2013/0032513 A1 describes a device by means of which a bulk material can both be dried and simultaneously separated into a coarse material fraction and a fine material fraction.
  • the object of the invention was to provide a possibility of making the sighting effect of a static classifier changeable in the simplest possible way.
  • the invention is based on the one hand on the idea that the volume flow of the sight gas guided through the static classifier represents a control variable which can be easily influenced, the change of which has a relevant effect on the Sighting effect of the sifter.
  • the particle size distributions of the material discharged from the static classifier on the one hand as fine material and on the other hand as coarse material can be adjusted by changing the volume flow of the classifying gas. This can be done, in particular, depending on the aggregates downstream of the static classifier (for example a mill or a dynamic classifier).
  • a change in the drying effect of the (possibly heated) sight gas can also be achieved by adjusting the volume flow.
  • the volume flow of the sight gas could in principle be adjusted to the intended sighting effect by correspondingly controlling a blower generating the sight gas flow.
  • the volume flow of the classifying gas for an aggregate downstream of the static classifier, in particular a dynamic classifier is also changed.
  • the invention provides, on the one hand, for the volume flow of the sight gas supplied to the static classifier, which can preferably be air, to be regulated in such a way that at least one bypass channel is provided, via which part of the sight gas flow is applied is led past the visual space.
  • a generic static classifier which has at least one housing in which the visual space is located, in which one or more ventilation shelves are arranged and in the classifying material of classifying gas, in order to separate the classifying material into fine and coarse material, whereby (at least ) a classifying gas inlet and (at least) one classifying material inlet lead into the classifying room and (at least) one fine material outlet and (at least) one coarse material class exit from the classifying room, characterized by at least one bypass channel integrated in the housing for bypassing the classifying room, the bypass channel going out in the classifying gas inlet and flows downstream of the visual space.
  • a viewing space is understood in particular to mean the area of the sifter in which material sifting, that is to say a separation of material, is more specific Grain size is done.
  • the material of coarser grain size leaves the visible space through the coarse material outlet, the material of finer grain size entering the fine material outlet.
  • the fine material outlet is arranged downstream of the visual space and is designed in such a way that no material is viewed in it.
  • the bypass channel opens into the classifier downstream of the classifying space, the bypass channel opening, for example, into the fine material outlet or into a gas inlet of a second, in particular dynamic, classifier downstream of the first classifier.
  • a bypass duct integrated into the housing is understood to mean that at least one (preferably all) wall surface delimiting the bypass duct, preferably extending over the entire length of the bypass duct, is part of the housing and thus, in addition to the function of delimiting the bypass duct, structurally (as a supporting wall) or used functionally (e.g. to guide a medium) for other parts of the classifier.

  • the fine classifier is a dynamic fine classifier, which accordingly comprises a rotatingly driven classifying rotor arranged in the second classifying chamber, for example in the form of a conventional classifying basket.
  • Such a sifter which comprises a static coarse sifter and a fine sifter connected downstream of it, can preferably be used in combination with (at least) one blower used for both (partial) sifters to generate the sifting gas flow.
  • the ability to influence the volume flow of the sighting gas through the bypass duct through the static coarse sifter has advantages in particular in the case of such a combination with a fine sifter, since in this way the volume flow through the static coarse sifter can be largely regulated independently of the volume flow through the fine sifter.
  • a control element can preferably be provided, by means of which the free flow cross section of the bypass channel can be changed (manually or automatically).
  • the control element can be designed, for example, as a control flap or control slide adjustable by means of an actuator.
  • the bypass channel forms a plurality of (spatially separated) flow channels.
  • bypass channel it can then be provided, in order to even out the partial flows of the sight gas that are conducted via the individual flow channels, that a control element is provided for several and in particular all of the flow channels. It can also be provided that the control elements can be adjusted separately.
  • the flow channels end at a distance from the mouth of the bypass channel into the fine material outlet.
  • a combination of the partial flows of the sight gas conducted via the flow channels can be particularly advantageous if the sight gas flow conducted through the bypass channel is introduced into the fine material outlet via a relatively small mouth opening in the area of the mouth of the bypass channel compared to the cross-sectional dimensions of the fine material outlet.
  • the bypass channel opens decentrally into the fine material outlet, whereby a swirl of the re-mixed total flow of the visible gas can be generated by means of the sight gas flow entering the fine material outlet, which in particular has a positive effect on the visual effect of the static coarse sifter downstream, dynamic fine classifier.
  • the direction of rotation of the swirl corresponds to the sight gas flow of the direction of rotation of the sight rotor of the dynamic fine classifier.
  • “Decentralized” is understood here to mean that the (middle) flow direction of the sight gas flow entering the fine material outlet from the bypass duct (and in particular the central longitudinal axis of the mouth opening) is the central longitudinal axis of the Cross-sectional areas of the fine material outlet in the area of the mouth of the bypass channel do not intersect.
  • the sight gas flow entering the fine material outlet from the bypass channel is introduced as far as possible from the central longitudinal axis and thus as close as possible to a wall of the housing delimiting the fine material outlet.
  • the classifier according to the invention has at least two bypass channels, which can preferably be arranged on opposite sides of the first classifying room, for an increased swirl effect the sight gas flows entering the fine material outlet from the two bypass channels can be provided that these two bypass channels are not only decentralized but also open diametrically to each other with respect to a central longitudinal axis of the fine material outlet in the fine material outlet.
  • At least one intermediate wall arranged in the fine material outlet and oriented transversely to the ventilation floor or floors can be provided.
  • the intermediate wall can stiffen the housing.
  • an increase in the load-bearing capacity for the main flow as a result of an increase in the Froude number can be achieved by the at least one intermediate wall, which divides the flow space formed by the fine material outlet for the main flow of the sighting gas into a plurality of partial flow spaces.
