Definitions

  • the invention relates to a method for classifying coarse-grained material according to the preamble of claim 1 (cf. DE-OS 25 35 881).
  • the material to be sifted occurs at a speed which results from the task of filling a funnel directly above the viewing zone (cf. FIG. Of the aforementioned publication).
  • the material enters the viewing zone in a high material concentration that still does not allow any precaution.
  • the object of the invention is to improve the viewing result with these horizontal cross-flow views, in particular to achieve a high degree of selectivity with large feed quantities and a small line of sight.
  • This object is achieved with the measure according to the characterizing part of claim 1.
  • This measure has the effect that the material to be sifted is dispersed even before it enters the viewing zone, namely that larger and smaller, ie heavier and lighter, material stocks parts is avoided by achieving a comparison with the prior art, higher speed, according to claim 2 particularly effective by reaching the respective speed of the free fall, are separated from each other before reaching the viewing zone ', whereby the adverse concentration of Gut politicianser upon entry into the viewing zone.
  • the deflection of the falling movement from the vertical depends on the size of the individual good components, their density and their vertical speed. The larger this is, the shorter the dwell time in the viewing zone and the less the distraction.
  • the invention teaches that the individual good components can be separated very sharply by entering the viewing zone with the considerable differences in terms of their vertical speeds, according to claim 2, for example, with their falling speed.
  • the measure according to claim 3 shortens the distance required to speed the good components .
  • To achieve claim 1 or 2 and accelerates the good components either so that they are then delayed again in whole or in part or so that only a residual acceleration is required.
  • Claim 4 is based on the achievement of an average falling speed, with the lighter material components due to the air resistance slowed down and the heavy material components were further accelerated before they entered the field of vision.
  • the housing 1 comprises an elongated, cylindrical or cuboid housing 19, the open end faces of which are closed by flanged covers 30, 31.
  • the housing 19 has on its upper side in the area of the cover 31 a filling opening 25, which is adjoined at the top by an input shaft 20.
  • At the bottom of the housing 19 there are two openings 32a and 32b, on the edge of which a separating device 33 is flanged.
  • This comprises two dispensing funnels 34 and 36 arranged one behind the other in the longitudinal direction of the housing, the openings 26 and 28 of which are each connected to an airlock 37, which in turn has its off outlet openings 41 each in an associated collection container 9 and 11 open.
  • Airlocks can be provided as airlocks 37, as indicated in the example shown.
  • the cover 30 extends like a chimney from the right open end of the housing 19 upwards and is flanged at its upper end to a pipe 38 which is only partially shown. This leads to a cyclone 22, which applies a vacuum to the cover 30.
  • the cyclone 22 is also connected via its exhaust line 24 to the suction side of a blower 1, which is fastened centrally in the end wall of the cover 31.
  • the fan 1 sucks in air from the cyclone 22 via the exhaust air line 24 and conveys an air flow 2 into the interior 4 of the housing 19.
  • a perforated distributor plate 39 is attached to the left, open end face of the housing 19 in order to homogenize the air flow 2.
  • the connection of the covers 30 and 31 to the cyclone 22 and the attachment of the airlocks 37 to the openings 26 and 28 enable a closed air circuit for the air conveyed through the interior 4.
  • the material components falling into the interior 4 of the housing 19 via the filling opening 25 are detected in the viewing zone 3 by the air flow 2 of the blower 1 and, depending on their weight, are carried more or less far to the right through the interior 4.
  • the trajectory described by the good components is shorter the greater its weight.
  • Very fine material components pass from the interior 4 (see arrows 8) via the pipeline 38 into the cyclone 22, through whose lower opening 29, which is closed off by an air lock 40, these material components fall into a collecting container 12.
  • a cellular wheel sluice 23 is provided, which accelerates the goods placed above them and releases them into the input shaft 20 at such a speed that the lighter material components are decelerated and the heavier material components further accelerate in the viewing zone 3 in the interior 4, which in the leads to an improved classifying result.
  • Fig. 2 shows that in the system of Fig. 1, the input shaft 20 has been replaced by a drop shaft 21 also attached to the top of the housing 19, eliminating the cellular wheel sluice.
  • a feed hopper 18 is placed on top of the chute 21, into which a feed chute 17 projects. The abandoned good falls over this through the chute 21 and through the fill opening 25 into the viewing zone, not shown in FIG. 2.
  • the length of the chute 21 is dimensioned such that the material to be sifted, at least in the scope of its main components, has approximately reached the speed when it passes through the fill opening 25, which it achieves in free fall. As explained above, this leads to a good sifter result.
  • the cellular wheel lock 23 is operated according to FIG. 1, for example, in such a way that its peripheral speed is approximately 2 m / s with a length of the input shaft 20 of 0.5 to 2 m, and according to FIG 2 the height of the chute 21 is a few meters, for example by 4 m.
