Definitions
- the invention relates to a sifter with a housing which forms a viewing space, in which one or more aeration trays are arranged and in the reformgut is traversed by classifying gas to separate fines from coarse material, a reformgaseinlass and reformguteinlass open into the viewing space and a Leave the fines outlet and a coarse material outlet from the viewing area.
- Such classifiers serve to separate bulk solids into two fractions having different particle size distributions.
- the separation of the fractions takes place in the viewing space, in which the sighting material falling from the prepareguteinlass in the direction of Grobgutauslasses flows through the viewing gas in the transverse direction. In doing so, smaller particles are entrained by the sight gas flow and transported to the fine material outlet, while larger particles are discharged via the coarse material outlet.
- aeration floors of a static classifier are aligned more or less transversely to the direction of movement of the goods to be seen, in many cases a step-like arrangement of the ventilation floors is provided (DE 43 37 215 AI).
- a substantially planar formed ventilation floor is provided with a plurality of ventilation slots.
- the ventilation floor can be composed of a plurality of individually exchangeable slotted plates.
- the material to be seen falling in the viewing space hits the ventilation floor (s) where it is flowed through by the classifying gas.
- Static classifiers are often combined with dynamic classifiers, whereby the static classifiers are regularly preceded as a coarse classifier by the classifier which serves as a classifier.
- Dynamic classifiers are based on one
- a combination of a static classifier as a coarse classifier and a dynamic classifier as a classifier in a circulating grinding plant for cement clinker is known for example from DE 43 37 215 A1.
- the static sifter is followed by a roll press and is acted upon by this comparatively coarse and a plurality of scabs exhibiting prepare for the static classifier.
- the coarse material separated in the static classifier is returned to the roll press, while the fine material is fed by means of the stream of sight gas to a tube mill, in which it is further comminuted.
- the tube mill the prepares the dynamic classifier, in which a separation of the prepare for the body of the body.
- the fines are then discharged as finished goods in a separator from the classifying gas, while the central fines are returned to the tube mill.
- the static classifier and the dynamic classifier are separated both spatially and functionally by the interposition of the tube mill.
- the static sifter thus essentially serves to avoid feeding too large particles or slugs to the tube mill.
- a device for sifting bulk material in which a static sifter and a dynamic sifter are integrated directly one behind the other into a common housing and thus through which the same sifting gas stream flows, is known from DE 10 201 1055 762 A1.
- the upstream of the static classifier essentially serves to avoid exposure of the rotationally driven and comparatively sensitive viewing basket of the dynamic classifier with large particles and slugs.
- DE 24 56 970 C3 discloses a dynamic classifier in whose housing a bypass channel bypassing the viewing area is integrated, via which part of the dust-air mixture supplied via an inlet can be guided in the classifying chamber to avoid sighting , As a result, targeted influencing of the particle sizes should be possible in the finished product leaving the dynamic classifier.
- the invention has the object to provide a way to provide the sighting effect of a static classifier in the simplest possible way changeable.
- the invention is based on the idea that the volume flow of the visual gas guided through the static separator is an easily controllable controlled variable whose change has a relevant effect on the sighting effect of the classifier.
- the particle size distributions of the material discharged on the one hand as fine material and on the other hand as coarse material from the static sifter can be adjusted by changing the volume flow of the classifying gas. This may be done, in particular, depending on the aggregates downstream of the static sifter (e.g., a mill or a dynamic sifter).
- a change in the drying effect of (optionally heated) the visual gas can be achieved.

- the area of the classifier is understood, in which a Materialsichtung, so a deposition of material of certain grain size takes place.
- the material of coarser grain size leaves the view space via the coarse material outlet, with the material of finer grain size entering the fines outlet.
- the fine material outlet is connected downstream of the viewing space and designed in such a way that no material separation takes place therein.
- the bypass channel opens downstream of the viewing space into the classifier, wherein the bypass channel, for example, in the fine material outlet or in a gas inlet of the first classifier downstream of the second, in particular dynamic, classifier.
- a bypass channel integrated in the housing is understood to mean that at least one (preferably all) wall surface bounding the bypass channel and preferably extending over the entire length of the bypass channel is part of the Housing is and thus in addition to the function of limiting the bypass channel structurally (as a supporting wall) or functionally (eg for guiding a medium) is used for other parts of the classifier.
- one or more advantages can be generated in comparison with an externally extending bypass channel, which may be designed, for example, in the form of a bypass tube.
- an externally extending bypass channel which may be designed, for example, in the form of a bypass tube.
- Compensators which may be required in an externally extending bypass channel to compensate for different thermal expansion, can be omitted in a built-in housing bypass channel.

- Such a separator which comprises a static coarse sifter and a fine sifter downstream therefrom, can preferably be used in combination with (at least) one blower used for both (partial) sifter to generate the sight gas flow.
- the influenceability of the guided through the static coarse sifter volume flow of the visual gas through the bypass channel has advantages especially in such a combination with a fine sifter, since in this way the Volume flow through the static coarse sifter largely independent of the volume flow through the fine sifter can be made adjustable.
- it may be provided to design the total volume flow of the visual gas supplied to the classifier via the classifying gas inlet with respect to the volumetric flow requirement of the classifier and to adapt the regularly lower volumetric flow requirement of the gross classifier by passing a more or less large part of the total volume flow to the (first) classifying room of the gross classifier.
- a control element may be provided, by means of which the free flow cross-section of the bypass channel (manually or automatically) is variable.
- the control element may for example be designed as adjustable by means of an actuator control valve or control slide.
- the bypass channel forms a plurality of (spatially separated) flow channels.
- bypass channel can then be provided to equalize the guided over the individual flow channels partial flows of the sight gas, that in each case a control element is provided for several and in particular all of the flow channels. It can also be provided that the control elements are separately adjustable.
- the flow channels terminate at a distance to the mouth of the bypass channel in 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 sight gas can be generated by means of the sighting gas flow entering from the bypass duct into the fine-material outlet, which in particular has a positive effect on the visual effect of the static coarse sifter downstream, dynamic fine sifter can affect.
- the direction of rotation of the swirl of the sighting gas flow corresponds to the direction of rotation of the classifying rotor of the dynamic fine classifier.
- the term "decentralized” is understood here to mean that the (middle) flow direction of the sighting gas flow entering from the bypass duct (and in particular the central longitudinal axis of the orifice) does not intersect the central longitudinal axis of the cross-sectional areas of the fine-material outlet in the region of the mouth of the bypass duct in that the sighting gas flow entering from the bypass duct into the fine-material outlet 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 separator according to the invention has at least two bypass channels, which can preferably be arranged on opposite sides of the first viewing space, it can be provided for an increased swirl effect of the sight gas flows entering the fine material outlet from the two bypass channels that these two bypass channels not only in each case decentralized but also diametrically opposed to each other open into the fine-material outlet with respect to a central longitudinal axis of the fine-material outlet.
- At least one intermediate wall arranged in the fine-material outlet and oriented transversely to the or the aeration bottoms can be provided.
- the intermediate wall can cause a stiffening of the housing on the one hand.
- an increase in the capacity for the main flow due to 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 visual gas into a plurality of partial flow spaces.
- the intermediate wall does not obstruct the introduction of the sight gas flow conducted via the at least one bypass duct as far as possible, it can preferably be provided that the bypass duct opens downstream of the intermediate wall into the fine material outlet.
