Definitions
- the invention relates to a mill classifier, in particular a roller mill classifier according to the preamble of the claim 1.
- Wälzmühl classifier which in a roller mill or in a roller mill, for example in an air-flow mill, can be arranged integrated or placed on this, can be designed as static or dynamic classifier be. Also known are combinations of static and a dynamic classifier, which then too be referred to as Hocheffectsichter.
- a high-efficiency judge is in ZKG, 46th year (1993) issue 8, pages 444 to 450, Figure 7 described.
- the sifter points a cylindrical strip rotor and a concentrically arranged Leitklappenkranz on.
- a possible effective tangential flow between the static Diaphragm and the inguinal rotor are generated so that the Coarse particles can not get to the rotor.
- disadvantage are an increased pressure loss and increasing wear the guide flaps, especially at high particle concentrations.
- a mill classifier which has two superposed Leitklappenkränze.
- the baffles are adjustable around vertical axes arranged, wherein the guide flaps of the Leitklappenkränze independently have mutually supported axes.
- a stationary ring is provided and the adjusting devices are at opposite ends the guide flaps arranged.
- the cylindrical used in the aforementioned mill classifiers Last or Stabkorbrotor usually has a Number of bars, which is at least twice as high as
- the so-called standard classifiers is what with relatively high Cost of production is connected. Also the suspension and Storage of a bar coring machine differs from the Rotors of the standard classifier and contributes to the higher manufacturing and installation costs.
- a well-known standard classifier is the Loesche gyro / Basket classifier type LKS (ZKG, 46th year (1993) Heft 8, p. 446, fig. 5).
- This dynamic sifter is called cone-shaped Ingot rotor formed and has a double cone rotor with screwed visible strips on.
- the slanted rotor bars correspond to the flow from below and lead to a weak deflection of the regrind fluid flow.
- the invention has for its object to provide a mill classifier, in particular a roller mill classifier, which has exceptionally low production costs in a particularly simple construction and at the same time allows great flexibility and optimization of the visual processes.
- the guide flap s such a shape design and positioning on that no so-called Cyclone flow arises, but a regrind fluid mixture without an upstream static vision stage immediately is spotted dynamically.
- a roller mill classifier with a strip rotor of basically known design and a concentric Leitklappenkranz arranged around the strip rotor provided with flow-optimized vanes, which um a vertical axis of rotation are adjustable and one of the Mill ascending regrind fluid flow to a tangential to radial flow of the rotor bars of the inguinal rotor to force.
- rotor strips are preferably used, as they are from the LKS classifiers are known, but at least in the area the guide flaps vertically and thus parallel to the guide flaps are arranged.
- vanes with a rounded Leading edge and at least one arranged thereon Guide plate, such that approximately parallel or expanding Flow channels formed between two vanes be and the inflow and outflow is approximately equal.
- baffles In conjunction with the rounded leading edge arises a parallel flow without constriction in the outflow and by a particularly advantageous streamlined Formation of the baffles an expanding outflow with diffuser effect, with a recovery of pressure energy and thus a reduction of the flow resistance connected to the classifier.
- deflectors enter between two deflectors Flow channel formed with a nozzle effect.
- a cost-effective production, installation and easy adjustment the flow-optimized vanes can be achieved when, as a rounded leading edge, a cylindrical or tubular Anströmraj, e.g. a flow pipe, is used, on which the baffle tangential arranged, for example welded. It is also possible, the baffle indirectly, for example via a attach additional mounting plate to the flow pipe. While the mounting plate, which relatively can be kept narrow, fixed directly to the flow pipe can be, the baffle can be releasably attached to the mounting plate attached, for example, be screwed. In case of wear of the baffle is in this way a relatively quick, inexpensive replacement possible.
- the flow pipe is circular cylindrical and made of an abrasion resistant material, and the axis of rotation the guide flaps is from the longitudinal axis of the flow pipe educated.
- This has the advantage that both the holder of the guide flaps, for example via Pivot, in the area of the classifier housing, and the adjustment from outside the classifier housing extremely low can be carried out.
- baffles are particularly advantageous for flow channels with diffuser effect.
- These can be formed for example by two baffles be, which on the Anström emotions or Anströmrohr be attached tangentially.
- both baffles substantially identically formed and with rotor-side edge regions abutting one another, i. leak.
- the second sheet can be narrower than the baffle, which the debutgutstrom facing, be formed and with a other angle of attack than the preparegutstrom facing Baffle be attached to the Anström emotions to a to cause opening flow channel with diffuser effect.
- the whole Reaching the rotor area are the heights of the baffles and the rotor bars matched.
- a strip rotor which a converted double cone rotor a Loesche gyro / basket classifier is the cylindrical rotor area above a conical rotor area to be dimensioned such that the vertical standing rotor strips of the cylindrical rotor portion approximately have the same height as the concentrically arranged Deflector flaps of the Leitklappenkranzes.
- the conical rotor area may advantageously be covered by a cover, e.g. a covering cone, which between the cylindrical and conical Rotor area is arranged, fluidically ineffective be made.
- a cover e.g. a covering cone
- the mill classifier according to the invention not just the rotor bars of the inguinal rotor like formed at LKS, but it can also be the classifier housing, at least the top of the classifier housing, the Bearing cartridge and also the drive and the drive shaft like be formed in a Loesche gyro / basket sifter. It is advantageous that the lower cone of the double cone rotor omitted and shortened the drive shaft can be.
- the classifier housing familiar from the LKS classifier can be taken in principle, but with the space for the rising regrind fluid flow over the height of the Leitklappenkranzes is narrowed, causing the Particle flow into the flow channels of the Leitklappenkranzes is accelerated into.
- the mill classifier according to the invention makes it possible to use the entire Grist particles from fines to coarse material to the inguinal rotor to supply to a purely dynamic sighting.
- This Particle flow is after passing through the grinding gap between the grinding rollers and the grinding track in the fluid stream spun, flows as regrind fluid flow on the periphery the grinding bowl upwards and is through the Leitklappenkranz without prior separation of coarse particles in transported the inguinal rotor.
- the inguinal rotor singles by centrifugal separation, the coarse particles from the total particle flow by removing the coarse particles from the inguinal rotor be thrown against the Leitklappenenden where by gravity as oversize into the semolina recirculation cone fall.
- FIG. 1 and Figure 2 mill classifier An illustrated in Figure 1 and Figure 2 mill classifier is a Wälzmühl classifier 2, which on a Wälzmühle can be put on.
- the roller mill is by grinding rollers 37 and a grinding track 39 indicated.
- the roller mill classifier 2 has a classifier housing 23 with a top 25 a dynamic separator part 6 and a static vane ring 4 for an upflowing Grist-fluid mixture 3 on.
- a dynamic separator part 6 is a known per se Strip rotor 16 with a cylindrical rotor portion 8 and a conical rotor portion 18 is used, which in relation on number and training, especially in terms of the radial width of the rotor strips 7, as well as in relation to a storage cartridge 24, one above, not shown drive and a drive shaft 26 substantially a double cone rotor of a Loesche gyroscope / Basket sifter corresponds.
- the conical rotor portion 18 is by a veneer, which by a cover cone 28th is formed in conjunction with the semolina cone 31, ineffective made.
- the classifier housing 23 and the upper part 25 of the classifier housing 23 were in principle from the Loesche gyro / KorbSichter, a standard classifier, adopted, taking However, the classifier housing 23 in the region of the cylindrical Rotor region 8 tapers or narrows and upwards a "retracted" housing shape 38 results.
- the mill classifier 2 shown in FIG. 2 corresponds in terms of of the classifier housing 23 except for the retracted Housing form 38 and in relation to the classifier housing upper part 25, the bearing cartridge 24, drive shaft 26 and in the form and radial extent of the rotor strips 7 also known
- the aforementioned LKS Standard reformer has in Contrary to the classifier of FIG. 1 no conical rotor area 18, but only a cylindrical rotor area 8 with vertical rotor strips 7 in the narrowing Housing 38 on.
- a double cone 35, as in the mill classifier 2 according to FIG. 1 is no longer present.
- Matching Features of the mill classifier 2 according to FIGS. 1 and 2 are provided with identical reference numerals.
- the guide flap ring 4 of the mill classifier 2 in the figures 1 and 2 is provided with flow-optimized baffles 5, which can be adjusted about a vertical axis of rotation 9 (see Figs. 3 to 5).
- the baffles 5 are so trained and arranged that in a viewing room 20 between the strip rotor 16 and the Leitklappenkranz. 4 no centrifugal flow, but a tangential flow until radial flow of the inguinal rotor 16 takes place (see Figs. 3 and 5).
- Flow-optimized baffles 5 of the Leitklappenkranzes. 4 are shown by way of example in FIGS. 3 to 5.
- a first training variant are in Fig. 3 in comparison to the rotor strips 7 shown enlarged guide flaps 5 with a rounded leading edge 10 and a baffle 11 provided, which directly and tangentially to the rounded Leading edge 10 is attached.
- Such baffles 5 are shown in FIG. 3 as lower deflectors, while the two upper baffles 5 streamlined are formed and next to the baffle 11, which the Ground material-fluid mixture 3 or facing the reformgutstrom is still have a sheet 12.
- the sheet 12, which the Is away tangent stream, is also tangential to the rounded leading edge 10, which advantageously a circular inflow pipe is attached.
- baffle 11 and Sheet 12 of the two upper streamlined baffles. 5 of Fig. 3 are formed largely identical and are with rotor-side edge portions 21, 22 to each other and thus run "pointed”. Streamlined baffles 5 but are not limited to this training variant.
- FIG. 4 shows alternatively trained vanes 5 with a Anströmrohr 10, a vertical axis of rotation 9 on the Longitudinal axis of the flow pipe 10, with a guide plate 11 and a sheet 12.
- the baffle 11 is not directly on the Flow tube 10, but via an additional mounting plate 17 and releasably attached to this. In this way can the exposed to wear baffle 11 replaced and be renewed.
- both the Guide plate 11 and the flow pipe 10 made of an abrasion resistant Material made or at least partially an abrasion resistant coating and / or surface structure on.
- the plate 12 and / or the additional mounting plate 17 may be formed abrasion resistant.
- FIG. 4 clarifies that the angle of attack of indirectly fastened Guide plate 11 and / or the plate 12 the same or different can be chosen, which makes either parallel or expanding flow channels 13 formed and a sighting according to the respective requirements can be achieved.
- FIG. 5 shows by way of example two rotor strips 7 of a strip rotor 16 shown.
- the rotor strips 7 are basically Z-shaped, but have at their the Leitklappenkranz 4 facing the end of a rounded Leg 27, which leads to a lower resistance and leads to a higher bending stiffness.
- the shown in Fig. 5 Guide vanes 5 have a rounded leading edge 10 also a flow pipe, whose vertical axis the axis of rotation 9 of the baffles 5 forms.
- the baffles 5 are provided with a baffle 11, which indirectly, namely on fastening devices, such as mounting plates 17, is held on the flow pipe 10. While the mounting plates shown in Fig. 4 17 angled are formed are for the baffles 5 according to Fig. 5 uses flat mounting plates 17, which attached tangentially to the flow pipe 10, for example welded, are.
- FIGS. 3 and 5 The for a purely dynamic sighting of the mill classifier 2 intended employment of the Leitklappenkranzes 4 with respect to the rotor strips 7 is apparent from FIGS. 3 and 5.
- FIGS. 3 and 5 the guide flaps 5 are at an angle set at about 60 °, allowing a flow the radially oriented rotor strips 7 and a rejection Grobgutpelle 32 takes place while the fines get into the inguinal rotor 16.
- Figure 5 is at the bottom Guide flap 5 shown that the coarse particles 32 of the Z-shaped rotor strips 7 thrown towards the guide flap 5 and in this flow-minimized area fall down into the semolina cone 31 (see FIGS. 1 and 2).
