Definitions

  • the invention relates to an air vortex mill for the Mahltrocknüng a flowable product with a gas / air flowed grinding chamber with a plurality arranged in the grinding chamber grinding stages formed by a rotor with a plurality of refining plates and a stator housing, and with a device for feeding the product into the grinding chamber ,
  • impurities can not be avoided or filtered out, especially in the case of viscous products, so that even foreign bodies in the suspension can clog nozzles.
  • the use or pre-mixing of compressed air with the nozzle and possible cooling of the nozzle did not give the desired result.
  • the present invention has for its object to remedy the problems described in an air vortex mill of the type mentioned.
  • the shaft 7 of the rotor 4 are in a conventional manner (see. EP 226 900 A2 ) Grinding discs 8, the peripherally vertically arranged grinding plates 9 carry. From the cylindrical housing 2 supported, the refining plates 9 facing baffles are not shown.
  • the substantially vertically extending rotor axis is denoted by 10, the outlet of the mill 1 by 14.
  • the rotor 4 On its underside, the rotor 4 is equipped with a fan disk or an impeller 11. It ensures a sufficient supply of preferably hot carrier gas, e.g. Air which is supplied to the mill during operation via the connecting piece 12 (arrow 13).
  • a hot carrier gas e.g. Air which is supplied to the mill during operation via the connecting piece 12 (arrow 13).
  • the product supply lines 6 shown in Figures 1 to 7 are located in the lower part of the grinding chamber 3. They are each equipped with an outwardly guided connection piece 15, via which the supply of product takes place (arrow 16). Inside the grinding chamber, the supply lines 6 outlet openings 18 forming holes through which the supplied product enters the grinding chamber 3. The outlet openings 18 are distributed substantially uniformly over the circumference of the grinding chamber 3. The diameters of the bores amount to one to several mm depending on the supplied product. Suitably, they are designed such that the product is sprayed substantially vertically upwards.
  • the hot air entering through the nozzle 12 is directed radially outwards in such a way that it efficiently carries the injected or sprayed product along (arrows 20 in FIGS. 2 and 4) ).
  • the supply lines 6 are each formed as a ring lines, which include the lower portion of the grinding chamber 3.
  • the goal of the substantially uniform product supply would also be achieved by a supply line 6, which is formed as a ring section, the lower portion of the grinding chamber 3 only partially, preferably predominantly comprises.
  • the supply line 6 may consist of several sections that can be easily disassembled and cleaned externally. In addition, it may be expedient to provide an externally operable device, with the help of which the cross section of the outlet openings 18 is variable.
  • spacers 21 are provided, which are fastened to the housing wall 2 and carry the ring line 6.
  • the ring line 6 is supported on further, not visible spacers, which extend between the bottom of the mill 1 and the ring line 6.
  • FIG. 6 shows a mill 1 designed according to the invention with a supply line 6 triangular in cross-section.
  • a a pump 23, whose outlet is connected via the supply line 16 to the connecting piece 15, be conveyed from a reservoir 24 in the loop 6.
  • More viscous products can be supplied in a manner known per se via a screw 25 (variants b and c).
  • Component of variant (c) is still an upstream mixer 26, in which the crude product with already dried product or other materials, such as support materials, additives or the like, can be mixed.
  • another line 27 is shown, which opens into the product supply line 16. It can - if necessary - supply the gas with increased pressure, e.g. Compressed air, serve. Such pressurization has the effect of increased flowability of the product and a reduction in the risk of clogging of the feed apertures 18.
  • the ring line 6 of the embodiment of Figure 6 is equipped with two mutually approximately opposite connection piece 15 and 28. At the connecting piece 28, a line 29 connects, which opens into the reservoir 24. Through line 29 is product that has not entered through the outlet openings 18 in the grinding chamber 3, circulated. This solution makes it possible to regulate the pressure in the loop 6 by controlling the pressure in the return line 29 (for example by means of an adjustable bottleneck 30).
  • the outlet 14 of the mill 1 is connected via the line 31 to a filter 32.
  • the promotion of the dried product is used in a conventional manner the connected to the separator 32 fan 33.
  • the final product passes through a rotary valve 34 in a conveyor means, here a screw conveyor 35, the outlet is designated 36.
  • the screw 35 is also connected via a line 37 to the supply of hot air serving connection piece 12. about this way, a "back-powdering" can be carried out, which, since the partially recycled, already dry product is fed to the grinding chamber 3 together with the hot air, is particularly effective.
  • Figures 8 and 9 show an embodiment of a mill 1 according to the invention with a loop 6, which is located outside of the grinding chamber 3. Via a plurality of preferably bent tubes 41, the ring line 6 is connected to the grinding chamber 3. The located within the grinding chamber 3 ends of the tubes 41 form the outlet openings 18 for the product to be dried.
  • the product to be dried from the plurality of outlet openings 18 enters the grinding chamber 3.
  • the supplied via the connecting piece 12 and with the aid of the annular disc 19 and the impeller 11 in the direction of the outlet openings 18 directed hot air takes the product and promotes it in the grinding gap between the refining plates 9 and the baffles, not shown. There is an effective turbulence and drying, depending on the product and a further crushing instead.
  • the final product exits the mill at 14 and is - as shown for example in Figure 7 - fed via a filter to another conveyor 35.
  • the invention also allows a thorough cleaning and subsequent drying of the grinding chamber 3.
  • cleaning liquid via the supply line 6 in the grinding chamber. 3 sprayed.
  • the drying takes place by means of hot air, which is expediently also supplied via the feed line 6 to the grinding chamber 3 in this case.
