Definitions
- the invention relates to a separator according to the preamble of claim 1.
- Such separators which are also suitable for industrial use, in particular also in continuous operation, are known per se from the prior art.
- the invention has the object to go a different way and to realize a compact and cost-producible separator, in which nevertheless a separation of the motor area from the storage area or -raum is feasible.
- the stator is rigidly connected to the machine frame, the motor rotor, the drive spindle, the centrifugal drum and preferably the housing form an elastically supported on the machine frame, oscillating in operation unit and the entire storage device - for the drive spindle - is between the motor and the drum arranged. Since the stator is supported directly on the machine frame and the motor rotor sits directly on the drive spindle, when using only a few components a particularly compact vertical design can be realized.
- the inventive arrangement of the bearing device between the motor and the drum allows an axially short design, in which the bearing area and the engine are structurally but so separated or separable that the lubrication of the bearing device can be separated from the engine, resulting in arrangements in which the engine is arranged between a neck bearing and a foot bearing is not the case. Nevertheless, the engine can still be supported with its stator directly in the machine frame.
- the oscillating unit is in particular designed such that the fulcrum, in particular the precession movement in the axial and radial center of the rotor or motor rotor is or not so far deviates from the center that the motor rotor can not rotate freely in the machine housing. This ensures that no contact between the motor rotor and the drum can occur, especially during operation.
- the separator drive is designed such that the relative movements between the stator and the motor rotor caused by the construction according to the invention are reduced to a minimum, so that it is possible to arrange the motor rotor in the oscillating system and the stator in the non-oscillating machine frame What a particularly compact and cost-effective design allows.
- the oscillating mass of the system is kept small because only the rotor of the engine is involved.
- the vibration tuning is preferably "supercritical" designed so that the oscillating system of drum, drive spindle and motor rotor designed with a low natural resonant frequency is stored in the ultra-jacks, the natural resonant frequency is relatively far below the usual operating speed range of the drum. that the system runs in operation relatively stable with only small deflections, since the resonance frequency is already passed through during startup at relatively low speed of the drum.
- the motor rotor is rotatably connected directly to the drive spindle or integrally formed therewith.
- the design extending elements such as a clutch can be omitted in this way. In addition, the manufacturing costs are further reduced.
- FIG. 1 is a sectional view of a first schematically illustrated separator according to the invention
- Fig. 2 is a sectional view of a second separator according to the invention schematically shown.
- Fig. 3 is a sectional view of a section of a third schematically illustrated separator according to the invention.
- a separator 1 shows a separator 1 with a centrifugal drum 2 with a vertical axis of rotation D, which is surrounded by a hood arrangement 17.
- the centrifugal drum 2 is mounted on a drive spindle 3.
- This is rotatably mounted in a housing 6 with a bearing arrangement which here comprises an (above bearing) neck bearing 4 and a (lower bearing) foot bearing 5.
- the neck bearing 4 here two rolling bearings.
- with only one bearing as a neck bearing 4 would be conceivable (not shown here).
- the drive region is shown below a bearing cover 32 in section. In the area of the drum and the hood, the spindle 3 is not shown
- a supply line - here a supply pipe 18 - allows a supply of liquid into the drum, in which preferably a disc package is used and which is preferably designed for continuous operation (not shown here).
- the housing 6 is supported by means of elastic elements, preferably by means of ultra sockets 7, on a machine frame 8.
- several of the ultra-sleeves 7 are distributed circumferentially distributed between a flange 9 of the housing 6 and an upper wall 10 of the machine frame 8, the longitudinal axes L of the ultra-jacks 7 being aligned at an angle to the drive spindle.
- the angle ⁇ between the drive spindle 3 or the axis of rotation D and the ultra-jacks 7 is preferably between 30 ° and 60 °.
- a Separatorantrieb with a (electric) motor 11 which has a motor housing with a stator 12 and a stator winding and a motor rotor 13 is used.
- the motor 11 advantageously has no own storage here, which allows a more cost-effective design.
- the bearing device is arranged between the motor 11 and the drum 1.
- the motor rotor 13 is so easily and advantageously arranged flying with respect to the drive spindle 3.
- the drive spindle 3 is directly - ie preferably without intermediate elements such as a coupling - connected to the motor rotor 13.
- the motor housing with the stator 12, however, is rigidly and unsprung arranged on the machine frame 8 and supported on this.
- the centrifugal drum 1 with the drive spindle 3, the motor rotor 13 and the housing 6, a vibrating unit which is elastically supported on the machine frame 8, but to which the stator 12 does not belong, so that between the motor rotor 13 and the stator 12 relative movements occur.
- the separator drive is designed in such a way that the center of rotation M of the oscillating system (the centrifugal drum 2 inter alia precesses during operation) lies in the axial and radial center of the motor rotor 13.
- the pivot point M and the center - as shown in Fig. 1 - exactly match.
- they differ slightly from one another, as long as it is ensured that the motor rotor 13, which carries out the oscillation of the drive spindle 3, can still rotate freely in the stator 12 without touching it.
- the position of the pivot point M of the oscillating system or the oscillating unit is defined by the Ultra Bushes 7 and their arrangement.
- each perpendicular S intersect through the middle of the longitudinal axes L of the Ultra Bushes 7 each exactly in the fulcrum M.
- the separator drive is designed such that the relative movements occurring between the stator 12 and the motor rotor 13 during operation are reduced to a minimum.
- a fan 14 is arranged, which sucks air from below through a frame opening 15 in the machine frame, this promotes through the engine 11 and blows off at a further opening 16 of the machine frame 8.
- the stator 12 is sealed to the machine frame 8 down and the supply or frame opening 15 is positioned directly under the drive spindle 3.
- Such a pump-like construction is realized in a simple manner with the help of the fan 14.
- the fan wheel could also be driven with its own (small) drive, so that a "separate fan", ie an independent, decoupled from the drive spindle ventilation would be realized.
- the advantage of this embodiment is a ventilation regardless of the speed of the motor rotor, so that a uniform cooling would be ensured.
- a cooling device can be installed with water, as it is known from water-cooled engines.
- the machine frame can then be carried out correspondingly tight.
- Fig. 2 shows a construction in which a partition wall 19 in the machine frame 8 separates the axial section in which the motor 11 is received from the axial section which receives the bearing device with the neck bearing 4 and the bottom bracket 5.
- the partition wall 19 is brought close to the drive spindle, but does not rotate with this.
- the rack opening 15 for sucking air through the motor 11 and the rack opening 16 for discharging this air are both disposed in the lower axial portion of the machine frame below the partition wall.
- the machine frame 8 may be formed closed except for the frame openings 15 and 16 in this lower portion.
- FIG. 3 A further construction is shown in FIG. 3, the nature of which corresponds to the illustration of FIGS. 1 and 2 and which may be configured with respect to the elements not shown here, such as the separators shown in these figures.
- the bearing device for the drive spindle 3 is arranged completely above the motor 11 according to FIG.
- a pot-shaped sleeve 21 is applied to the drive spindle 3, which is rotatably connected to the drive spindle 3.
- the sleeve 21 has an upper ren, inside hollow sleeve portion 22 and a lower disc portion 23 which is connected to the drive spindle and the drive spindle 3 passes through downwards.
- the bearing housing 6 has an upper flange 24 and a lower sleeve-like housing portion 25, which passes through an upper opening in the machine frame 8 and engages with its lower end in the upwardly open sleeve 21.
- the motor is located below the sleeve 21 (not visible here).
- an inwardly projecting, circumferential collar 26 is formed at its upper end.
- the inner peripheral edge of the sleeve portion 22, the lower disc portion 23 and the drive spindle 3 forms a ring-like lubricant chamber 28 for receiving a film of lubricant.
- this lubricant space 28 extends a radially from the lower sleeve-like portion of the bearing housing 6 outwardly into the lubricant annulus 28 extending, tubular projection 29 in the manner of a pump or similar to a non-co-rotating peeling disc in a discharge channel 30th for the lubricant passes, which initially extends radially inwardly and then in the bearing housing 6 upwards and exits outwardly therefrom.
- skiving plate-like projection 29 By means of the skiving plate-like projection 29 with the downstream discharge channel 30, it is possible during rotations of the drum or spindle 3 to pump off lubricant under pressure from the lubricant space 28 and to return it to the storage facility, for example via a line 31 connected downstream of the non-rotating bearing housing. without the mist or splashes arise.
- line 31 units of various types can be turned on, such as a filter 20 and / or a cooler. Due to the pump-like effect can be beneficial to a separate or external pump can be omitted as an aggregate.
- such may be provided, for example in order to demand the oil for lubrication in rolling bearings of the bearing device (not shown here).
- Fig. 3 can also be dispensed with the intermediate wall 19, since the sleeve 21 itself completes the lubricant area for storage.
