Definitions

  • a flow of a fluid and solid particles suspended in the fluid is generated in a fluidized bed such that the solid particles are comminuted by energy exchange.
  • Part of the flow of solid particles below a certain mass or weight is branched off in a classifier and subjected to further processing, e.g. supplied in a filter, while solid particles remain above the aforementioned limit in the residual flow and the fluidized bed grinding are fed again until their mass or their weight is below the limit.
  • fluid bed flow is promoted by fluid jets that are introduced into the fluidized bed at high energy, causing the solid particles in the fluidized bed to undergo increased energy exchange.
  • This effect is particularly well achieved, even if the high-energy fluid jets are a suspension of fluid and solid particles, optionally the fluidized bed were removed, have experienced an increase in energy and then returned with their increased energy in the fluidized bed.
  • a fluid bed jet mill that includes an agitator that repeatedly delivers particles to the jet.
  • the agitator rotates on a vertical axis and thus pushes particles from a bed of good into the jets, as in claim 16 of the published patent application DE 20 40 519 is specified.
  • This particles are indeed returned to the rays, but it is achieved by far no optimal energy exchange of the particles to be separated solid particles.
  • the invention aims to improve the energy exchange of the solid particles to be separated.
  • the core of the invention for achieving the goal is, firstly, that centrifugal forces are exerted on the solid particles in the region of the penetration of the high-energy fluid jets into the fluidized bed in such a way that the energy exchange between the solid particles, which become parts of the high-energy fluid jets, already begins immediately after the penetration of the high-energy radiation into the fluidized bed and on the other hand generally the concentration of the solid particles within the fluid jets is improved.
  • This is inventively achieved in that a housing surrounding the fluidized bed for generating centrifugal forces rotates about an axis, so that the centrifugal forces act on the fluidized bed in the region of at least one fluid jet entering the fluidized bed in the energy.
  • the present invention thus shows ways in which the high-energy fluid jets with high energy can be introduced into the fluidized bed and thereby prevents the solid particles to be separated are first displaced into the fluidized bed without significant energy exchange.
  • the Fig. 1 illustrates a hot-steam fluid bed jet mill, as known in the art.
  • a cylindrical housing 1 encloses a chamber 2, which receives the fluidized bed 3 in the lower region and is the actual grinding chamber.
  • This fluidized bed 3 consists of fluid particles in a fluid, which are suspended more or less evenly distributed in the fluid. They have different masses and should be ground evenly to the finest particles.
  • 5 high-energy fluid jets 6, 7 injected, which pass through the fluidized bed 3, and that solid particles collide and are decomposed by the energy exchange.
  • the particles remain so long in the fluidized bed and in particular in the range of energetically entering the fluidized bed fluid jets 6, 7 until their mass has become so low that they of the upwardly directed beam 8 - the sum of the colliding and thereby the energy exchange between solid particles conveying individual energy beams into the fluidized bed 3 entering individual jets 6, 7 - are entrained, while the not yet correspondingly finely ground solid particles in the field of individual jets, ie remain in the actual fluidized bed 3 and further decomposed by energy exchange.
  • a fine-material outlet chamber 9 to which in turn the fine-material outlet nozzle 10 led out of the housing 1 adjoins.
  • the fine material particles leaving the mill through the outlet nozzle and suspended in a part of the fluid are sent for further processing, for example in a filter in which particles and fluid are separated from one another.
  • the ground material passes through a Mahlguteinlassstutzen 11 in the lid of the housing in the mill.
  • 12 is a steam supply for the rinsing rinsing between the stationary arranged in the housing 1
  • Feingutaustritsshunt 9 and a rotatably mounted classifying wheel 13 is referred to.
  • the classifying wheel 13 causes only very finely ground material to reach the outlet connector 10, while the material is not quite as finely grounded and exploits gravity as the original millbase gets into the fluidized bed 3 and is further decomposed there.
  • the drive 14 of the classifying wheel 13 is mounted outside of the housing 1 on the lid and functionally connected to the classifying wheel 13 through the housing cover.
  • the invention in the fluidized bed jet mill according to the Fig. 1 be implemented by maintaining the rotation of the classifying wheel 13 with respect to the mill housing 1, the mill is brought in its entirety to rotate about its longitudinal axis.
  • the mill housing 1 is mounted at its upper and its lower end in suitable bearings 15, 16 and it is the mill housing 1 associated with a rotary drive 17, so that the mill is rotated by its drive at such a rotational speed or peripheral speed in that characterized in the fluidized bed by arrows and by the reference numeral 18, the inwardly directed jet forces counteracting centrifugal force and the transfugal and transpedalen energies are balanced against each other so that an energy exchange between solid particles of the fluidized bed and optionally the energy beams 6, 7 in the areas takes place immediately before the grinding nozzles.
  • the nozzle 4, 5 and 11 ring chambers upstream and the nozzle 10 must be followed by an annular chamber, wherein in each case a part of the chamber wall of the mill must be associated mitcardend and another part of the chamber wall must be stationary, both chamber wall parts are sealed from each other.
  • Fig. 1 While it is in the mill according to the Fig. 1 is a known, originally fixed fluidized bed jet mill, which has been redesigned according to the invention by bringing the housing 1 to rotate about its longitudinal axis 1a is the fluidized bed jet mill according to Fig. 2 designed according to the invention from the outset.

  • a second cover plate 2.9 is opposite to the first cover plate 2.7 and is interspersed by a fine material outlet 2.10, so that suspended by the Feingutauslassrohr 2.10 the suspension of carrier fluid and suspended therein, ground to the desired low mass solid particles, ie the ground to a desired degree of fineness of the product Milling chamber 2.6 discharged and can be fed to further processing.

Same parts are therefore in both Figures 2 and 3 denoted by the same numbers behind the figure hint 2 and 3, respectively. Due to the floating bearing with the two bearings 3.19 and 3.20 there is a greater degree of freedom in the utilization of the space on the other side of the mill.
