Definitions
- the invention relates to a cyclone classifier with the features of the preamble of claim 1.
- the invention also relates to a method for influencing the particle size distribution of powders using a cyclone classifier of this type.
- the grain distributions are subject to ever increasing demands. It is no longer only relevant to maintain a certain upper particle size; Compliance with a certain particle size distribution is also required, and this varies depending on the application, usually with regard to the fine fraction.
- the present invention has for its object to provide a cyclone classifier of the known type with improved classification properties, thereby expanding its working range.
- the built-in elements in the cyclone classifier according to the invention achieve a controlled flow guidance which, compared to the prior art, provides improved classification results. It is essential that the lower, conical installation forms a defined gap with the housing. This gap is decisive for the improved classification properties of the cyclone classifier according to the invention.
- the grain size of the powders to be processed can be influenced by adjusting the gap size.
- FIGS. 1 to 5 exemplary embodiments for cyclone classifiers according to the invention, which are shown schematically in FIGS. 1 to 5.
- the housing of the cyclone sifter 1 is designated by 2, its upper section by 3, its middle section which tapers conically downwards by 4 and its lower section by 5.
- the upper section 3 there is a classifier 6. Only the classifier wheel is shown schematically.
- the upper section is laterally equipped with a carrier gas / product inlet 7 (preferably arranged tangentially) and with a carrier gas / fine material discharge 8 (arranged centrally).
- the axis of the system is designated 9.
- an installation 10 which is open at the top and bottom and tapers downwards (at least in the area of its lower section), the upper diameter of which is larger than the diameter of the classifying wheel 6. It can extend into the upper, preferably cylindrical section 3 of the housing 2 and end immediately below the classifier wheel 6.
- the second installation 1 1 which is spaced below the lower opening tion of the installation 10 is arranged and has the shape of a flared cone shell.
- This conical installation 1 1 is attached to the installation 10 adjustable in height.
- a strut 12 attached to the installation 10 is provided, on which a support 13 of the cone 11 can be adjusted in height, for example by means of a thread.
- the lower housing section 5 is equipped with a coarse material outlet (not shown in detail) (indicated by the arrow 14).
- a coarse material outlet (not shown in detail) (indicated by the arrow 14).
- pipe connections 15 for the supply of secondary gases, preferably secondary air, are provided. These can open radially into the lower housing section 5 ( Figures 1, 4 and 5).
- Tangential pipe connections 15 are shown in Figures 2 and 3.
- the solutions according to these figures differ in the direction of rotation of the vortices that are generated by the incoming secondary air flows (arrows 16, 17).
- the product / carrier gas stream enters tangentially at the level of the classifying wheel 6 into the upper section 3 of the housing 2. Very fine particles follow the carrier gas through the classifying wheel 6 and leave the housing 2 through the carrier gas / fine material discharge. The remaining portion of the registered product / carrier gas flow flows downward in the annular space between the installation 10 and the outer housing 2 in spiral paths.
- the installation 10 has the known purpose of separating the carrier gas / particle flows directed downwards in the peripheral region and upwards in the central region.
- the lower installation 1 1 forms a defined gap 18 with the outer housing 2.
- the carrier gas / particle flows directed downward are further classified.
- This sighting is particularly effective sam, if with the help of secondary air, supplied via the pipe connections 15 on the lower housing section 5, a countercurrent is generated in the area of the gap 18.
- the fine material separated in the gap 18 is again led through the interior of the installation 10 to the sifter 6.
- the product that passes through the gap 18 is discharged as coarse material.
- the conical installation 1 1 has on the one hand the task of preventing the product located in the lower region of the housing 2 from rising again due to flow turbulence.
- the size of the gap 18 influences the fine fraction of the fine material. Because the size of the gap 18 can be adjusted, the fine fraction of the fine material can also be varied.
- the installation 10 has a conical shape which tapers downward over its entire height.
- the plane of its upper opening lies immediately below the classifying wheel 6.
- the plane of its lower opening lies in the region of the middle height of the conical section 4 of the outer housing 2.
- FIGS. 4 and 5 show further designs of the installation 10. Similar to the housing 2, it has different sections.
- a lower conical section 10a and an upper cylindrical section 10b are provided.
- the transition from cylindrical to conical is approximately the same height as in the outer housing 2 (transition from section 3 to section 4).
- the upper opening of the installation 10 is initially followed by a section 10c which widens conically downwards. This section can merge - as shown in FIG. 5 - into the cylindrical section 10b or directly into the conically tapering section 10a.
- the cyclone classifier according to the invention not only has improved classification properties; it also allows the size of the fine fraction of a fine-grained powder to be influenced in a targeted manner.
- Tests have shown that the fine fraction ⁇ 10 ⁇ can be varied within relatively large ranges. Simply by changing the secondary air volume flow or the peripheral speed of the classifying wheel, the fine fraction can already be set in a range between a first (smaller) value and a second value increased by up to 70%. This particle size distribution can also be influenced by changing the size of the gap 18.
- the size of the gap 18 was approximately 10 mm (with a diameter of the lower edge of the cone 11 of approximately .130 cm). By changing the height of the cone 11, the gap 18 can be adjusted over a wide range.
