Definitions

  • the invention relates to a storage and mixing silo for bulk material, containing a storage space in a common silo body and a mixing space provided in the lower area of the silo body, smaller than the storage space and designed as an annular chamber, which communicates with the feed inlet opening via the in the inner boundary wall of the annular chamber
  • the storage room is connected and has at least one material outlet opening, further comprising devices for pneumatic ventilation, in particular floor ventilation, of the storage room and the mixing room.
  • a central mixing room is provided, in the peripheral wall of which a number of material inlet openings are provided which connect this central mixing room with the floor section of the storage room surrounding it.
  • a walk-in ring channel is arranged around the peripheral wall of the mixing chamber and inside the silo body, from which silo facilities can be monitored and operated. The arrangement of the ring channel around the mixing space alone results in an undesirable structural effort, without the mixing effect being influenced solely by the arrangement of this ring channel.
  • the bottom area of the storage space is surrounded by an outer annular channel, the inner boundary wall of which forms the lower outlet slope of the storage space.
  • This ring channel is connected to the storage space in the circumferential direction via a plurality of product inlet openings.
  • the mixing space is formed by a type of annular chamber which practically represents an axial lower continuation of the storage space and is separated from this storage space only by a flat funnel-shaped bottom.
  • a vertical hollow column which on the one hand supports the center of the store room floor and on the other hand contains a central feed opening from the store room to the ring mixing room; in addition, a transverse partition is arranged within this hollow column, so that the material outlet, which is also centrally arranged at the lower end of this hollow column, is covered upwards.
  • the invention is based on the object of designing a storage and mixing silo of the type mentioned in such a way that, with structurally advantageous dimensions, a mixing and homogenizing effect which is further improved compared to the known designs mentioned can be achieved.
  • the material inlet opening and the material outlet opening to the annular chamber mixing space are offset from one another, in particular approximately diametrically opposite one another, the bulk material located in the mixing space, namely all the bulk material particles, must always cover an equally long mixing distance on which the Bulk to be mixed must pass through the different, independently ventilated floor ventilation zones.
  • the mixing intensity in the area of the individual floor ventilation zones can be influenced in an advantageous manner due to their independent ventilation option. Because of the arrangement of the material inlet opening and the material outlet opening to one another, a high mixing performance can be achieved, since part of the bulk material introduced into the mixing chamber is fed to the material outlet opening in one circumferential direction and the other part in the other circumferential direction.
  • the values mentioned with regard to the radial width and lower vertical height of the annular chamber have proven to be particularly favorable for this good mixing effect.
  • the silo storage space has a downwardly inclined, funnel-shaped bottom
  • an inner vertical boundary wall of the annular chamber is formed on the lower edge of the funnel-shaped bottom of the storage chamber, up to the central one ventilated bottom part of the pantry-reaching, cylindrical wall part connects.
  • a central deep lowering space is obtained at the lower end of the storage space, which is particularly favorable with regard to a large feed rate from the storage space into the mixing space, the feed inlet opening from the storage space to the mixing space being arranged in the inner boundary wall of the annular chamber.
  • a structural advantage also arises in that the part of the silo body located below the - preferably strongly inclined - funnel bottom design of the storage space can simultaneously be used as an annular chamber mixing space.
  • the material outlet opening in the outer boundary wall of the annular chamber is at a higher level than the material inlet opening in the inner boundary wall.
  • the material inlet opening is preferably located approximately at the bottom of the annular chamber.
  • a particularly advantageous embodiment of this construction can also be seen in the fact that the material inlet opening is assigned a radially between the inner and the outer annular chamber boundary wall, towards the outer boundary wall slightly inclined, upwardly open overflow channel, the Determine the upper overflow edges of the crop level within the ring chamber.
  • a closable residual emptying outlet opening is expediently provided in the outer annular chamber boundary wall below the material outlet opening at the level of the annular chamber base.
  • a further advantageous embodiment of the invention consists in that of the floor ventilation zones between the inlet and outlet openings of the annular chamber, the zones directly adjacent to the inlet and outlet openings are always strongly ventilated, with at least two partial ventilation zones in between in the floor circumferential direction and these partial ventilation zones in the order from Area of the product inlet opening to the product outlet opening can only be ventilated alternately periodically.
  • This measure allows the mixing and homogenizing effect in the mixing space designed according to the invention to be further intensified and controlled with the aid of pneumatic floor ventilation, so that, for example, not only a movement of the mixed material from the inlet opening to the outlet opening (in both circumferential regions that are approximately opposite one another) Annular chamber), but also superimposition of up and down movements and possibly even back and leading movements of the mix along the mixing path from the inlet opening to the outlet opening of the mixing chamber.
  • the annular chamber can form a continuous mixing space in the circumferential direction.
  • the annular space could contain a partition wall diametrically opposite the product outlet opening.
  • the overflow channel assigned to the inlet opening is expediently designed jointly for both partial mixing spaces. so that the intensely mixed bulk material quantities brought up from the two partial mixing rooms can also be mixed with one another in the area of the material outlet opening.
  • This embodiment of the silo according to the invention is particularly well suited for continuous mixing operation, although a discontinuous mixing operation would also be possible, especially if it was carried out with two partial mixing rooms.
  • FIGS. 1 and 2 A first exemplary embodiment of the storage and mixing silo is first described with reference to FIGS. 1 and 2, which is intended in particular for fine-grained and powdery bulk material.
  • the silo contains, in a common silo body 1, a storage space 2, which by far takes up the largest volume, and in its lower area a mixing space 3, which is smaller than the storage space 2 and which is formed by an annular chamber 4.
  • the annular chamber 4 forms a mixing chamber 3 which is continuous in the circumferential direction (cf. FIG. 2).
  • the annular chamber 4 is formed by an outer boundary wall 5, which can simultaneously be the outer wall of the silo body 1, further by an inner boundary wall 6 and by a bottom 7 and an inclined top wall 8, which is the inward inclined, funnel-shaped bottom of the storage space 2 and therefore runs obliquely inwards from the upper region of the outer boundary wall 5 to the vertically oriented inner boundary wall 6.
  • the inner boundary wall 6 thus adjoins the lower edge of the funnel-shaped bottom (top wall 8) of the storage space 2.
  • This inner boundary wall 6 is therefore formed by a cylindrical wall part of this storage space reaching to the central, ventilated base part 9 of the storage space 2, this resulting in a central, deep lowering space 2a in the lower region of the storage space 2.
  • a product inlet opening 10 is provided in the area of the annular chamber base 7.
  • This material inlet opening 10 to the mixing space 3 is assigned a collecting conveyor 11 which is arranged in the central base part 9 of the storage space 2, preferably in such a way that it traverses this central base part 9 diametrically.
  • the collecting conveyor 11 can be a pneumatic conveyor trough, which is associated with conventional pneumatic loosening units 12 on both sides, which are also incorporated in the central base part 9.
  • This product outlet opening 13 can be assigned in the usual manner, for example, product outlet elements for blocking and metering. It is important, however, that this material outlet opening 13 of the outer boundary wall 5 is at a higher level than the material inlet opening 10 on the chamber floor 7 in the inner boundary wall 6. Assign boundary wall 6 or 5 extending overflow channel 14, which is slightly inclined towards the outer boundary wall 5.
  • This overflow channel 14 can be in the form of a simple inclined discharge chute or else in the form of a pneumatic conveyor channel or in the form of another suitable conveyor element be educated. In any case, the overflow channel 14 is open at the top, and the upper overflow edges of the channel are approximately horizontal and of the same height, so that the product level S within the mixing chamber 3 is determined thereby.
  • annular space mixing chamber 3 can also be completely emptied if necessary, there is also a closable residue emptying outlet opening 16 in the outer annular chamber boundary wall 5 below the material outlet opening 13 at the level of the annular chamber base 7. It is also useful if the annular chamber 4 is inclined at its bottom 7 from the material inlet opening 10 in the circumferential direction (in both circumferential halves of the annular chamber 4) to the residue discharge outlet opening 16, as indicated in FIG. 1.
  • the radial width B of the annular chamber 4 should be between 0.25 times and 0.37 times the value, preferably between 0.3 and 0.35 times the value of the inner diameter of the silo D, while the inner and outer boundary wall 5 and 6 of the annular chamber 4, at least in their lower region, run vertically over a height H which is between 0.7 times and 1.4 times, preferably between 1.0 and 1.2 times Value of the radial width B of the annular chamber 4 is. If the annulus 1 as inclined in the example of FIG. 1 in the direction of the residual discharge outlet opening 16, the vertical height H is then approximately the average height in the peripheral area between the product inlet opening 10 and the residual discharge outlet opening 16.
  • the annular chamber floor 7 between the material inlet opening 10 and the material outlet opening 13 or the residue emptying outlet opening 16 is divided into several partial ventilation zones 17, 18, 19, 20, 21, 18 ', 19', 20 ', 21' in a sensible manner, as is is illustrated in Fig. 2.
  • Each of these partial ventilation zones 17 to 21 or 18 'to 21' can be pneumatically ventilated independently of one another, for which purpose a number of porous ventilation units are arranged in the chamber floor 7 and are acted upon by a ventilation device which can be controlled separately with respect to the ventilation floor of the storage room 2.
  • the partial ventilation zone 17 assigned to the material inlet opening 10 and the partial ventilation zone 21 directly assigned to the product outlet opening 13 are always heavily ventilated during operation, preferably with the same amount of pressure being applied.
  • the upper part of the annular chamber 4 forms a kind of relaxation space and that in a peripheral region of the annular chamber 4 a vent pipe 22 opens out into this upper relaxation space, for example with a filter device or only with can communicate with the upper part of the pantry.
  • FIGS. 3 and 4 A second exemplary embodiment of the storage and mixing silo is illustrated in FIGS. 3 and 4, FIG. 3 in comparison to FIG. 1 of the first example only showing the left half of the silo body 31, while the right half, not shown, in exactly the same way can be carried out, as has been explained with reference to FIG. 1.
  • the silo body 31 contains a storage space 32 and one opposite that Storage space 32 smaller mixing space 33, which is formed by an annular chamber 34.
  • the outer structure of the annular chamber 34 is initially designed in the same way as the annular chamber 4 in the example of FIGS. 1 and 2, that is to say it contains an outer boundary wall 35, an inner boundary wall 36, a chamber floor 37 and one from the upper region of the outer boundary wall 35 obliquely downward inward to the inner boundary wall 36 cover wall 38. Also in this second embodiment, the radial width B and the height H of the at least in their lower region vertically extending boundary walls 35, 36 are defined in exactly the same way as for Part has been explained with reference to the silo inner diameter D with reference to Figures 1 and 2.
  • annular chamber 34 is divided into two partial mixing spaces 33a, 33b, each of which has its own feed inlet opening 40a, 40b in the inner boundary wall 36.
  • the inlet opening 40a, 40b to each partial mixing space 33a or 33b is in turn connected to a collecting conveyor 41a, 41b arranged in the central base part 39 of the storage space 32, which - as shown in FIG. 4 - is a branch of a main collecting conveyor 41 can.
  • annular chamber 34 of this embodiment In its ring section which lies diametrically square above the outlet opening 43, it has an accessible operating space 45 which is accessible from the outside via a correspondingly large opening 46 in the outer boundary wall 35.
  • This control room 45 can still be used for fittings and blowers; in addition, closable access openings 48a and 48b to the partial mixing spaces 33a, 33b and to fittings in their areas are provided in the partition walls 47a, 47b.
  • the feed inlet opening 40a, 40b of each mixing space 33a or 33b is expediently arranged, as shown in FIG. 4, directly next to the associated partition wall 47a or 47b of the operating space 45.
  • the overflow channel 44 which is also designed and arranged in this case in the same way as in the first exemplary embodiment, is expediently designed for jointly receiving mixed material from the two partial mixing spaces 33a, 33b, so that the material outlet through the material outlet opening 43 can take place together.
  • the feed inlet opening 40a, 40b of each partial mixing space 33a or 33b lies in the region of the chamber floor 37, while the feed outlet opening 43 is at a correspondingly elevated level and with its overflow channel 44 the feed level, i.e. the Height of the filling in the partial mixing rooms 33a, 33b determined.
