Definitions
- the present invention relates to an extruding device comprising an extruder barrel, a screw and a rotary drive for the screw. It can be used particularly advantageously in particular large single-screw extruders, but it is also possible to use them in twin- or multi-screw extruders.
- Large single-screw extruders can be used, for example, in LDPE synthesis, ie in the production of low-density polyethylene, with current production rates of up to 60 t / h. be.
- Such systems represent a very high investment volume and are designed with high target operating times in the range of 8,000 hours / year. Any longer downtime represents a major economic loss for the operator.
- Another disadvantage is that in case of failures possibly upstream equipment such as cracker must be shut down at the same time.
- Extruders generally have an extruder barrel, a screw and a rotary drive for the screw rotatably mounted in an extruder barrel, which is connected for safe and lossless power transmission directly to the rotary drive.
- the rotary drive can be designed either as a direct drive or coupled via a gear motor.
- a thrust bearing may be required that absorbs the forces resulting from the head pressure. This is understood to mean the pressure exerted on the screw by the melt produced by the extruder.
- Such thrust bearings can be integrated either in the gearbox or in the direct drive or separately from them be provided. In this case, they are usually arranged between rotary drive and extruder cylinder.
- rotary actuators are used with gear, which have a variety of bearings and gears.
- gear which have a variety of bearings and gears.
- a thrust bearing is arranged, which is basically designed for a defined operating time. This is in the range of 40,000 operating hours, taking into account a statistical failure rate of approximately 10% of the bearings that fail before the nominal operating time is reached.
- the head of the extruder must be opened.
- the entire granulator must be disassembled and moved away from the extruder.
- the head connection between extruder and granulator must be disconnected, the flanges of the transport water circuit of the underwater granulator must be opened, the electrical connection of the granulator motor must be loosened, as well as the wiring of all sensors in the terminal box of the granulator.
- the screw After opening the head connection of the extrusion device, the screw can be pushed forward through the region of the head connection. This is usually done from the side of the rotary drive through the gear and the thrust bearing, so that the drive-side screw end releases the area of the transmission and the thrust bearing, thus no longer protruding into these.
- no separate shut-off valve is provided in the extruding device in the region of the feed funnel for the material to be processed, problems may arise with material still remaining in the feed funnel and the extruder barrel. Since the material in this case comes into contact with a region of the screw, which usually has no material contact, and this contaminated, it may later interfere with operation come.
- an intermediate housing which makes the connection between the thrust bearing and extruder and is generally divided along its center axis and thus obviously executed, can be at least partially disassembled, so that in the As a consequence, the pressure bearing centered between the rotary drive and the intermediate housing can be disassembled. Only then, if appropriate, can the gearbox be opened so that its components are accessible. If it is an error in the area of the thrust bearing, then the steps mentioned are also necessary to open this and reach the defective components can.
- Object of the present invention is therefore to provide a simple and inexpensive construction that allows easy assembly and disassembly of the individual components and assemblies of an extrusion.
- an extruder device has an extruder cylinder, a screw and a rotary drive for the screw, wherein the screw end facing the rotary drive does not protrude into bearings provided between extruder cylinder and rotary drive, in particular into a thrust bearing.
- This construction has proved to be particularly advantageous, since through them a avoid strong nesting of the various assemblies, resulting in a more modular design.
- the individual modules, such as rotary actuator, extruder barrel or bearings are more accessible.
- smaller extrusion devices can be constructed entirely without interposed bearings, so that in this invention, the screw does not protrude into the region of the rotary drive, but the rotary drive side screw end terminates substantially flush with the extruder cylinder or a possibly intermediate intermediate housing.
- the extruding device has a shaft which is connected with one end with a torque transmitting element of the rotary drive and the other end with the rotary drive facing the screw end rotatably transmitting power.
- the rotational force-transmitting connecting points can be configured both between the shaft and the worm and between the shaft and the rotary drive so that they are easily detachable.
- the screw due to the intermediate shaft does not penetrate all following the extruder cylinder in the direction of the rotary drive components.
- the torque transmission is taken over in this area by the shaft.
- the shaft can be positively and detachably connected to the rotary drive and / or the rotary drive facing the screw end.
- a positive connection is particularly suitable for the rotary power transmission and suitable for easy detachable executable, so that even after long service life, a release of such a connection is possible.
- the shaft can be designed such that both the rotary drive and the worm are connectable to it via such a positive and releasable connection. In this way losses in the rotary power transmission can be avoided.
- the shaft passes through only possibly interposed assemblies, such as bearings, but does not rely on these or no connection with them.
- the disassembly is further simplified.
- the screw drive facing the screw end may have a recess with internal teeth for positive connection with the shaft.
- Such internal toothing represents a particularly simple, releasable and form-fitting rotational force-transmitting connection with a tuned shaft with corresponding external toothing.
- the extrusion device is designed such that the rotational force-transmitting element of the rotary drive in operation does not protrude into the extruder barrel or possibly provided between this and the rotary drive bearing, in particular in a thrust bearing.
- the torque transmitting element should end substantially flush with the rotary drive or a housing thereof.
- a disadvantageous interleaving of the individual modules is further reduced, the connection between the screw and rotating force-transmitting element via the shaft, which is preferably supported or mounted on any other element.
- the storage then takes place via the rotary drive on one side and the screw on the other side.
- the rotary drive can preferably have a hollow shaft as a torque transmitting element. This can be open on the extruder side.
- the shaft may be designed such that it can be positively and detachably connected to the hollow shaft of the rotary drive, wherein a positive connection via an internal toothing of the hollow shaft with an external toothing of the shaft is preferred.
- the rotational power transmission between the rotary drive and shaft takes place here in the region of the rotary drive, so that a clear functional and local assignment is given and the assemblies, apart from the shaft as a link, do not protrude into each other.
- the rotary drive can be designed such that the shaft can be pulled out of the rotary drive in a released state on the extruder counterpart side.
- Extruderussiseite here is the side facing away from the extruder cylinder understood.
- the connection between the rotary drive and screw can be easily solved and the shaft removed without further adjustment or disassembly steps.
- correspondingly suitable tools may be provided which allow, for example, a gripping of the shaft with a correspondingly opened rotary drive housing, so that it can be pulled after a possibly still required unlocking.
- a groove or the like could be provided in the rotary drive side shaft end, can engage in the corresponding claws of the tool.
- the screw facing the end of the shaft must have the same or a slightly smaller diameter than the hollow shaft of the rotary drive. If the screw end facing the rotary drive has a recess with internal toothing and the shaft has corresponding external toothing, it is particularly easy to ensure that the shaft is pulled out through a hollow shaft of the rotary drive.
- either both the hollow shaft and the recess of the screw end could have an identical internal toothing, so that the external toothing can be carried out over the entire wavelength.
- the external teeth could also be interrupted between the shaft ends such that the diameter of the shaft in this area is less than the minimum diameter of the internal toothing of the hollow shaft.
- a thrust bearing for receiving the axial pressure acting on the screw between the extruder cylinder and the rotary drive can be provided.
- a thrust bearing must intercept the very high axial forces acting on the worm, in particular in the case of large extruders, so that the rotary drive does not suffer any damage from them.
- Such thrust bearings are designed for long operating times, but can lead to long downtime in case of failure, if they are not easily accessible.
- Such a thrust bearing can be connected via an apparent intermediate housing with the extruder cylinder, which allows, inter alia, a centered connection of thrust bearing and extruder barrel.
- a pressure piece can be rotatably mounted, which transmits the pressure of the navanthebs districten screw end to the thrust bearing.
- the wave may be loose, i. without a fixed connection, be pushed through the pressure piece, which simplifies the disassembly.
- the thrust bearing can be easily decoupled from the rotary drive. If thrust bearing and rotary drive be connected centering, for example via corresponding projections and recesses, still a slight axial relative movement between the thrust bearing and rotary drive must be done before the thrust bearing removed, especially laterally or can be pulled up. For this purpose, an optionally provided intermediate housing can be removed. Since according to the invention but the torque transmitting element does not protrude further into the region of the thrust bearing, only slight axial relative movements must be performed, which further simplifies disassembly.
- a flange which is designed to be divisible and designed such that a centering connection between the thrust bearing and rotary drive can be effected by this.
- a flange is preferably divisible along its center axis, which is advantageously arranged horizontally. This results in a good accessibility of the area between the rotary drive and thrust bearing from above, assembly and disassembly are further simplified and individual modules are easy and directly accessible.
- a particularly preferred embodiment of the invention provides for a design of the rotary drive as a motor with gear or as a direct drive. This can be provided as a motor hydraulic, electrical or otherwise conventional drives.
- Figure 1 is a schematically illustrated extrusion device for LDPE according to the prior art
- FIG. 2 schematically shows a section of a design according to the invention
- FIG. 1 shows a prior art single screw extruding apparatus used for the synthesis of LDPE.
- the extruding device 1 has an extruder cylinder 2, in which a screw 4 is rotatably mounted.
- a granulating device 6 in the form of an underwater granulator is connected via a perforated plate.
- the melt is extruded through a perforated plate into a water-filled area.
- knives circle and cut the extrudate into granules, which are cooled by the water and simultaneously transported away.
- Such underwater granulators belong to the state of the art and will not be described in detail here.
- the extrusion device 1 is supplied by a low-pressure separator 8 with material to be processed, wherein this is shut off at the inlet into the extruder cylinder 2 via a shut-off valve.
- the so fed to the extruder cylinder 2 Material is degassed via a degassing device 10.
- an intermediate housing 12 connects to the left hand, which is designed to be divisible and by means of which a thrust bearing 14 and a gear 16 are connected to the extruder cylinder 2.
- Both the housing of the thrust bearing 14 and the intermediate housing 12 and the housing of the transmission 16 are designed such that they are centering connectable. Here this is represented by corresponding, interlocking projections and depressions of the individual housings.
- the intermediate housing 12 is designed to be divisible, so that it can be opened first.
- the transmission is rotationally driven by a motor, not shown, and transmits the torque to the screw 4, which is connected to the transmission 16 via a hollow shaft 18 which projects into the region of the thrust bearing 14.
- the connection takes place here via a toothing.
- FIG. 2 shows a section of the extruding device according to the invention in section.
- the screw 4 is designed such that it does not project into the area of the thrust bearing 14.
- Its rotary lifting end 4 "terminates substantially flush with the intermediate housing 12.
- the rotary drive-side screw end 4" is supported on a pressure piece 24 rotatably mounted in the thrust bearing 14, which transfers the pressure to the bearings.
- the shaft 20 passes through the pressure piece 24 without connection with the same, so that it can be pulled out of this as from a sleeve.
- the transmission 16 is inventively designed such that the hollow shaft 18, by means of which the rotational force is transmitted to the screw, does not protrude beyond the region of the transmission housing and in particular does not protrude into the region of the thrust bearing 14.
- the connection between the hollow shaft 18 and the worm 4 is produced by a shaft 20 which has external serrations at its two ends, which cooperate substantially positively with corresponding internal serrations of the hollow shaft 18 and a recess 4 'in the rotary drive-side worm end 4 " 16, the hollow shaft 18 thereof and the shaft 20 are formed such that the shaft 20 can be withdrawn through the gear 16 on the opposite side of the extruder, to the left in Figure 2.
- the shaft 20 are simply pulled out to the left through the gear 16, without causing a relative displacement of the screw 4.
- a flange 22 is provided, which is preferably divisible along its central axis, by means of which a connection between the housing of the transmission 16 and the housing of the thrust bearing 14 can be produced, wherein the flange 22 and the housing are formed such that they cooperate centering. This can be achieved by corresponding projections and undercuts in both the housings and the flange 22.
- the shaft 20 can be pulled out through the gear 16 due to the inventive design, in Figure 2 to the left, then the intermediate housing 12 at least one side of the extruder cylinder 2 and the thrust bearing 14 are separated and opened, so that already a part of the pressure bearing is accessible. If further measures are necessary, it can be opened by loosening the connection between thrust bearing 14 and gear 16 via the flange 22 and thereby, for example, the thrust bearing 14 are removed upwards. Alternatively, only in case of faults in the area of the transmission 16, the connection between the thrust bearing 14 and gear 16 could be solved via the flange 22, the flange can be opened and the gear 16 can be opened and taken apart or possibly lifted away to the top.
- a shaft 20 is provided as a torque transmitting element, it can be ensured that the interleaving of the various components is relatively low. As a result, the assembly and disassembly of the individual components is simplified. This is especially the case if neither rotary drive nor screw 4 elements that protrude into another component.
- the present invention can thus significantly reduce assembly times in the event of failure of bearings or gear parts.
- downtime reduction can range from 4 to 6 layers, which currently equates to a lost production loss of EUR 2 to 3 million.
- unplanned installation work carries an increased risk of unforeseen delays. Since the required working steps are also reduced in the case of unplanned disassembly and assembly work by the inventive design of the extrusion, the risk of unforeseen failures is reduced.
- extruding device Another advantage of the extruding device according to the invention is the fact that so far in disassembly work on extrusion plants where the rotary drive and possibly the thrust bearing were affected, both an extruder and a gear specialist were needed because the work on the rotary drive and / or on Pressure bearings also required strong modifications of the extrusion side. Due to the embodiment of the invention, only a specialist for the thrust bearing and the transmission or the drive is necessary. As a result, further savings can be achieved and increased availability of the system for the customer are possible.
