Definitions
- the invention relates to a classifying device for classifying granular Well, with a static cascade classifier as a caution chamber, the at least one rotatably arranged in the classifier housing, rod basket provided with turbo elements on the rotor circumference is connected downstream of the dynamic classifier part, with inlets for classifying air / classifying gas and classifiable material and outlets for classifying air / classifying gas, fine material, Medium and coarse goods.
- DE-A-42 23 762 describes a classifying device with an inside a common classifier housing housed a static classifier part without moving components and a dynamic classifier part with rotating Bar basket known.
- the static classifier part is used as a pre-sealing chamber to separate the coarse grain fraction contained in the granular material to be sifted trained, with two from the shaft-shaped classifier housing enclosed and between them forming a visual zone as well as from the Sight air in the cross-flow flow through view zone boundary walls diagonally down towards the discharge opening for the sighted Coarse grain fraction inclined cascade or louvered Have baffles, the two baffle walls and thus the one in between lying visual zone with a deviating from the vertical Angles are arranged obliquely.
- V-classifier Because in the static classifier part Visual air undergoes a V-shaped deflection, this is also referred to as a so-called V-classifier.
- a static V-classifier switched on e.g. B. in a circular grinding plant with a material bed crushing roller press or roller mill, has opted for energy-saving sifting and deagglomeration of the ground material in a single operation proven.
- the invention is therefore based on the object of a classifying device of the generic type with a static classifier part and immediately downstream dynamic classifier part with at least one rotatably arranged Form the rod basket so that the two separator parts are optimal can be operated economically coordinated, in particular in the case of moist visible material, namely the static V-classifier section as pre-classifier and possibly dryer and the dynamic classifier part as an instrument for Final sifting and, if necessary, residual drying.
- the classifying device has a bypass line via which a partial flow the sight air flow or sight gas flow leaving the static classifier part, deducted, for example, in an amount of about 20 to 80% is, so that only a smaller amount of sifting air / sifting gas in the downstream dynamic classifier part arrives with the rod basket which can be dimensioned smaller.
- the one contained in the bypass flow Solid material which is a mixture of middle goods and fines is separated from the bypass flow in an external solids separator and it can represent another product of the classifier. But this is particularly advantageous in the solids separator Bypasstrom separated product via a solid discharge line in the dynamic classifier part (re) introduced to this (re) introduced Product of a final sifting and, if necessary, residual drying in dynamic To undergo classifier part.
- the bypass line from the top of the classifier housing, and the solids separator for the bypass line can then be arranged above the classifying device be, the solid discharge line of the solid separator with Advantage is introduced from above into the dynamic classifier part. It exists but also the possibility of solids discharge from the external solids separator partially or entirely in the static classifier part. There is also the option of using the bypass line instead of from the top to let go of a side wall of the classifier housing and the solids separator for the bypass line possibly below the dynamic Arrange sifter part.
- the classifying device shown essentially in vertical section 1 has a V-shaped shaft-shaped housing 10 with two enclosed by the classifier housing and one between them Viewing zone 11 forming and of viewing air 12 or hot gas as Drying gas, for example in a cross-flow, through flow zone boundary walls, the diagonally down towards the discharge opening 13 for the selected coarse grain fraction 14 inclined cascade or have baffles 15a and 15b arranged in the manner of blinds, these two baffle walls and thus the one in between lying viewing zone 11 with a deviating from the vertical Angles are arranged obliquely.
- the good 16 to be sifted is placed in the good entry opening 17 on the Top of the static cascade classifier introduced.
- the visible material is viewed in cross flow and good agglomerates are deagglomerated at the same time.
- the visible material is moist 16 such as B. moist cement raw meal, this becomes effective at the same time dried if a hot gas is used as the visible medium becomes.
- perforated ones can also be used Sheets such as sieve sheets etc. are used.
- the rod basket 19 of the dynamic Sifter part in the embodiment of FIG. 1 with a horizontal Axis of rotation, can be dimensioned smaller because the rod basket 19 of the dynamic sifter then only the remaining V-sifter exhaust air reached, which is indicated by the arrow 20.
- the medium grain fraction 22 is carried out, at least one of the both ends of the rotating rod basket 19 by the arrow 23 shown sifting air / sifting gas fine material flow and for the purpose of separating the fine finished goods into a not shown Dedusting device performed.
- the bypass line 18, via which a partial flow of the classifying air Visible gas loaded with solids is withdrawn, whereby it for solids a mixture of a fine grain fraction and Medium grain fraction acts, leads to a separator 24 for separation of the solids 25 contained in the bypass gas stream, from above via line 26 into the dynamic classifier part for the purpose of final sighting and if necessary, residual drying are introduced. But there is also Possibility of solids 25 via line 27 as a separate product deduct.
- the solids 25 can also partially or entirely via line 28 into the feed opening 17 of the static classifier part be introduced.
- the solids separator 24 can be a separating cyclone, a dust filter, a classifier or be a different classifier. In any case, the solids separator 24 the sifting air / sifting gas flow largely freed from solids 29 deducted.
- the bypass line 18a does not work as in Fig. 1 from the top of the classifier housing 10, but from the left housing wall 30 approximately below the rod basket 19.
- This version can also be reintroduced of the solid withdrawn via the bypass line 18a into the dynamic and / or the static classifier part, as shown in FIG. 1 and described.
- a lock 21 for the discharge of the medium grain fraction 22 from the dynamic classifier part a snail, an air conveyor channel, a vibrating channel or a pneumatic one Suction etc. are used.
