Definitions

  • the invention relates to a separator according to the features of the preamble of claim 1.
  • DE 38 23 380 C2 discloses such a separator with a spreading plate on which the material to be treated is applied centrally. Over the circumference of the spreading plate impact elements on the upper side and radially outwardly projecting impact elements are fixed rigidly or freely oscillating below the outer edge.
  • the spreading plate is driven independently of the rod basket. On the spreading plate in the center of a task cone is arranged, which has the task of redirecting the falling feed on the spreading plate. Due to the centrifugal forces, the feed material slips to the edge of the spreading plate, wherein the feed material at the same time a component of movement in the direction of rotation of the spreading plate is mediated. At the edge of the spreading plate, the feed material hits the striking elements arranged on the spreading plate, so that the aggregates are comminuted at this point.
  • the particles of the feed material meet on outwardly projecting further impact elements of the spreading plate.
  • baffles which are arranged on the inside of the classifier housing above the viewing zone between the rod basket and the vane ring, the estate should be concentrated in the beat circle of the impact elements of the staff basket are passed. Despite various measures, deagglomeration is unsatisfactory.
  • DE 43 02 857 A1 discloses a cleaning device for cleaning a grain mixture comprising a spreader on which both a hood and a truncated cone is attached, which in turn carries a cone. Impact elements are not provided.
  • WO 2014/124899 A1 describes a sifter which has internals in the viewing zone between the air guidance system and the rotor cage, which are intended to cause the agglomerated feed particles to be at least partially disagglomerated. This should make a more efficient sighting possible.
  • the internals are arranged such that they extend parallel to the axis of rotation of the rotor cage or form an angle with the rotor axis.
  • the internals which can also be formed by end portions of the guide vanes of the air duct system, form bottlenecks or constrictions in the circumferential direction of the viewing zone.
  • the DE 199 61 837 A1 are also internals in the form of projecting into the viewing zone deflectors, which extend parallel to the axis of the dynamic rotor part.
  • EP 1 529 568 B1 discloses a cyclone separator in which the flow cross-section in the flow direction of the product is constricted in front of the separation region at at least one point.
  • diaphragms such as e.g. Conical rings are used, which can be installed in the viewing zone in several places.
  • the ratio ⁇ is meant, wherein X25 and X 75 denote the particle sizes of the particles, the proportion is 25% and 75%.
  • the separator according to claim 1 is characterized in that the task cone is arranged at a distance from the dispersing plate on the housing.
  • the particles of the feed material and in particular the agglomerates of the feed material have only one vertical and one radial movement component.
  • the agglomerates slide off the task cone, the agglomerates are caught and smashed by the dispersing blades of the dispersing disk rotating beneath the task cone.
  • the dispersing blades are arranged distributed on the upper side of the dispersing disk over the circumference of the dispersing disk.
  • dispersing blades Preferably, four to twenty dispersing blades are provided.
  • the impact of the dispersing blades is significantly greater than in the prior art, because the agglomerates on impact with the dispersing blades still have no component of motion in the direction of rotation of the dispersing.
  • the selectivity of the classifier is greatly improved because not only a significantly larger amount of agglomerates is deagglomerated, but the agglomerates are almost completely decomposed into their original individual particles.
  • the task cone has an opening angle ⁇ with 45 ° ⁇ ⁇ 90 °.
  • This is a pointed cone, which has the advantage that the slope of the conical surface is large and thereby the particles of the feed material in their vertical movement are slowed down only slightly before they hit the dispersing blades.
  • the object cone at its tapered edge has a radius Ri, for the 0.5 x R holds 2 ⁇ Ri ⁇ R2, where R2 denotes the radius of the Dispergiertellers. If this relationship is maintained, it is ensured that the cone edge of the task cone extends as far as possible to the edge of the dispersing plate and thus strike the particles of the feed material on a region of the dispersing disk and the dispersing blades which has a correspondingly high web speed v.
  • the impulse p m x v acting on the agglomerates is greater, the greater the web speed v. It is therefore advantageous to choose the radius R2 of the dispersing plate as large as possible, because then the radius Ri of the cone edge can also be chosen to be large within the range of 0.5 ⁇ R2 to R2.
  • the web speed v at the radially outer end of the dispersing blades is preferably in the range from 40 m / s to 150 m / s, in particular in the range from 80 m / s to 150 m / s.
  • Ri should not be chosen too large, so that the agglomerates falling from the task cone do not shoot over the edge of the dispersing disk due to their radial velocity. It is therefore preferred to choose Ri ⁇ 0.9 ⁇ R2, in particular Ri ⁇ 0.8 ⁇ R2.
  • the radius R3 of the inner circumference of the dispersing blades R 3 ⁇ Ri.
  • the inner circumference of the dispersing blades designates the circle on which the inner surfaces of the dispersing blades point radially to the center of the dispersing disk.
  • the advantage of a small distance A1 is that the agglomerates of the feed material are detected and smashed by the dispersing blades immediately after leaving the task cone.
  • each dispersing blade has a dispersing surface, which is arranged perpendicular to the direction of rotation of the dispersing plate. This has the advantage that a maximum force on the impinging agglomerates of the feed material is ensured.
  • the dispersing blades are upstanding at the top of the dispersing disk and extending in the radial direction.
  • a baffle ring is provided on the housing, which has distributed over the circumference, in the direction of the dispersing plate projecting baffle elements.
  • the baffle ring is preferably arranged stationary on the housing.
  • 24 or more than 24 baffles are provided.
  • the particles of the feed material which are thrown by the impact ring due to the centrifugal forces to the outside, not only hit against the baffle ring, but due to their component of motion in the direction of rotation of the turntable and against the baffles.
  • the advantage of the baffle ring with the baffle elements is that agglomerates, which may not yet have been completely broken down into the individual particles by the dispersing blades of the dispersing disk, can be effectively comminuted in this second stage of the dispersion. The deagglomeration is thereby further improved.
  • the distance A 2 between the impact elements and the dispersing plate is preferably 0 ⁇ A 2 -S 30 mm, in particular 10 mm ⁇ A 2 -S 30 mm.
  • the baffles are designed and arranged such that they face at least the dispersing blades. This means that the vertical extent of the baffles is so large that it corresponds at least to the height of the dispersing blades. This ensures that as many particles of the feed material leaving the dispersing plate are captured by the impact elements.
  • the sifter has a sifter wheel having sifter blades and an air guide system having guide vanes for supplying sifting air, an annular sifting space being arranged between the sifter wheel and the air guidance system.
  • Such classifiers are also referred to as Abweiseradsichter.
  • the vanes are in the viewing space protruding, extending in the vertical direction baffles.
  • This classifier does not have the dispersing plate and task cone according to the invention, but only the air-guiding system according to the invention.
  • the dispersing plate is preferably fastened to the classifier wheel.
  • the advantage is that the dispersing plate does not require its own drive and is driven by the classifier wheel.
  • the dispersing plate thus has the same angular velocity as the reformerrad.
  • the feed material in particular also the deagglomerated feedstock, tends to form strands in front of and in the viewing area which impair the classification.
  • Strands are understood to mean an accumulation of particles in a gas flow which, due to segregation, e.g. B. forms by the action of gravity and centrifugal force. Strands have their cause in exceeding the carrying capacity of the gas for the solid particles. In the strand thus smaller particles are included, which would otherwise arrive at low solids loadings with the flow of air into the fines. By projecting into the viewing space baffles a targeted loosening of the strands, so that an improved separation, in particular the finest particles is possible without affecting the rest of the deposition.
  • baffles By projecting into the viewing space baffles not only the strands are dissolved, but it is the particles of the feed material also imparted an additional component of movement in reformersrad direction.
  • the air duct system has air windows, wherein a baffle is arranged on at least one edge of the air window.
  • the air guidance system preferably has an annular wall in which the air windows are arranged.
  • the incoming air through the air windows is deflected by the baffles, whereby the flow is influenced in the viewing space.
  • the baffles thus fulfill two tasks. Both the particles of the feed material and the inflowing classifying air are influenced in the desired manner.
  • the angle of attack ⁇ of the baffles both flows can be adjusted specifically.
  • the angle of attack ⁇ is clamped between the baffles in the flow direction of the particle-air mixture in the viewing space and the inner radius RL of the air duct system.
  • the angles ⁇ are the same for all baffles.
  • the baffles are arranged on the opposite edges of the air window.
  • Each air window thus has two baffles, whereby the incoming air flow can be initiated more targeted.
  • the baffles between each two air windows are arranged such that their ends converge.
  • the baffles preferably have different angles of incidence ⁇ in this embodiment.
  • the ends of the baffles are preferably spaced, d. H. the ends of the baffles preferably do not touch.

  • the curved embodiment of the baffles has the advantage that the particle air flow is directed more effectively to the classifier wheel.
  • the baffles have a single radius of curvature R 4 .

  • the particle air flow has not only a horizontal component of motion, but also a vertical component of motion due to gravity.
  • the flow cross section of the viewing space in the vertical direction of movement is constricted by the cone ring, whereby the particle air flow is deflected by the cone-shaped surface of the particle guide element in the direction of bombarderrad. This measure also contributes to an improvement in the selectivity of the classifier.
  • the cone-shaped surface is arranged on the upper side of the particle guide element and forms with a vertical axis L v an angle ⁇ with 10 ° ⁇ ⁇ 90 °, particularly preferably 20 ° ⁇ ⁇ 80 °.
