Definitions
- the invention is based on a method or a machine (displacement engine or the like) for conveying conveyable media (gaseous, liquid, pasty or trickle-like) according to the preamble of the main claim or the secondary claim 2.
- Conveyors with an elastically deformable wall part of the work space are mostly known as a diaphragm pump, for example with a pendulum connecting rod drive (De-OS 2212322 or De-OS 19919908 and De-PS 2211096) or with a swash plate drive (De-OS 4244619) or the like.
- a peristaltic pump the drive of the elastically deformable wall parts (membrane, hose wall or the like) that delimit the working space in any case takes place by forces acting on these wall parts transversely to the direction of flow of the medium to be displaced.
- this drive is supplied with energy and is correspondingly transferred to the medium for conveyance, whereby it is is always an intermittent, not linear, promotion.
- this known the function of this known
- Displacement machines are e.g. in the case of a pendulum pump, a standing shaft with fixed intersection points on the fictitious axis, which also achieves extensive vibration compensation between the antinode and the oscillation valley.
- diaphragm pumps driven with slides in which several slides arranged one behind the other produce a delivery shaft for the medium to be delivered (there per hose pump), these are standing shafts. So or the like with peristaltic pumps. Pumps, like a rolling motion of a tire, compress the tube together to then radially expand again to generate the suction motion. It is either a smoothly reciprocating drive that generates a standing shaft or a continuous wave-like movement.
- the medium is conveyed, for example, via a screw in a space open at the top, for example, a groove, with the disadvantage that considerable losses occur due to the friction between the screw and the medium or the channel.
- Diaphragm pumps are also known in which the drive takes place via piezoelectric elements (De-OS 198934536 and De-OS 3618106) with fundamentally the same disadvantages and in particular also only suitable for small delivery quantities.
- the method according to the invention with the characterizing features of the main claim or the conveyor machine according to the invention and the characterizing features of the dependent claim 2 has the advantage that the intersections of the waves resulting from the type of drive resulting from the type of drive in the direction of flow when conveying the medium of the medium migrate, ie do not remain in one place or the intersection points with a fictitious flow axis move with the medium in the flow direction.
- Such traveling waves are known in nature during the movement of snakes, eels and the like. Accordingly, the wear on such a machine is distributed much more evenly between the driving and driven parts, and the medium is conveyed much more evenly.
- a pulsation is achieved by the drive system due to an additional, differently directed movement superimposed on the basic movement, which according to the invention is designed such that it generates the traveling wave in the medium.
- friction between the movable wall parts and the rigid wall is avoided or an output is avoided, which leads, among other things, to less wear and tear on the machine according to the invention and also to less noise and the possibility of using rigid, flexible wall materials.
- the materials, in particular the elastically deformable wall parts are less stressed than in known machines, these materials can be designed differently or in a thinner manner, but novel materials can also be used which would not be able to meet the requirements of the known machines.
- the resiliently deformable wall parts can be automatically reset in the pressure and / or suction direction - in contrast to known displacement machines of the generic type.
- the elastically deformable wall parts in Interaction with the wall parts opposite them, which delimit the working space and which are mostly rigid, achieves a seal running transversely to the direction of flow, similar to a single-walled hose pump, in which the walls opposite each other are usually pressed together in a transverse line.
- the flow rate of the medium can also be controlled up to the actual sealing, which also allows a higher pressure.
- a corresponding valve function is taken over by the interaction of the elastic deformable wall parts with the inflow and / or outflow opening of the working space.
- the seal given transversely to the direction of flow or this approaching between the elastic wall part and the rigid wall part can be designed as migrating in the flow direction, as a result of which the migrating wave of the medium can be influenced accordingly.
- the elastically deformable wall part of the work space is designed as a membrane, which is correspondingly transverse to the direction of flow for the desired drive can be acted upon.
- a membrane preferably has an elongated, for example oval, extension, the inflow opening being arranged on one of the longitudinal ends and the outflow opening on the other.
- a very favorable clamping and sealing can be achieved by such a membrane for the function of the machine, both in fast-running and in slow-running machines.
- the type of clamping can achieve a natural reset effect for certain designs.
- the drive consists of a crank mechanism and a connecting rod which transmits the lifting movement to the elastic wall parts, the connecting rod being guided along its predetermined path during its pendulum lifting movement in the lifting direction in order to generate the traveling shaft, so that the connecting rod passes through it the pendulum movement caused by the crank mechanism experiences an additional movement force (tilting movement) running transversely to the flow direction.
- This tilting movement generated by the pendulum movement and superimposed by the cam track guide can be a cam track guide in the connecting rod section between the crank mechanism and the elastic wall part, but it can also be arranged on the side of the crank mechanism facing away from the elastic wall part.
- the only decisive factor is that the pendulum movement caused by the crank mechanism is superimposed on a quasi-disturbance variable which turns the standing wave given by a pendulum movement into a traveling wave.
- one serves to transmit the pendulum tilting movement generating the traveling wave to the elastic wall parts laterally resilient form fit serves.
- a corresponding degree of freedom is achieved between the output end of the connecting rod and the point of attack of the elastic wall parts in the transverse direction.
- a sliding block which is arranged between the connecting rod end and the elastically deformable wall part, serves as a form-fit support.
- the interlocking support has a rectangular bar-like extension, the tilting movement of the interlocking support being transferred directly to the movable wall part.
- this pendulum tilting movement is passed on directly to the medium to be conveyed, which on the one hand causes a pulsating effect and on the other hand the traveling wave.
- an elastically resilient, rigid plate is arranged between the connecting rod and the elastic wall parts, via which the pendulum tilting movement carried out during the stroke is transmitted over a large area to the elastic wall parts.
- this plate can interact with the elastic wall parts in a floating manner, or else can be connected to them and be appropriately floating towards the end of the connecting rod. It is essential that this plate can have a corresponding support effect on the elastic wall parts, so that it can consist of a soft membrane for other practical reasons.
- the plate is made of resilient material, for example steel or harder plastic.
- the features mentioned in claims 9 to 12 can also be transferred to other drive means, at least whenever a drive takes place transversely to the elastic wall or membrane and there are similar problems.
- the pulsating work is achieved by means of a plurality of drive elements arranged transversely to the flow direction and one after the other and acting in a controlled manner on the elastically deformable wall parts (see above US 4854836 or also US 5961298).
- the elastically deformable wall parts are designed as a membrane with a longitudinal extension corresponding to the drive consisting of several elements.
- This membrane can be oval or almost rectangular, which essentially depends on which additional functions, for example valve functions, the membrane has to take over or how many drive elements are provided in succession and the like. More.
- a camshaft is used as the drive with the link slides assigned to the cams, which act at least indirectly (see also claims 9 to 12) on the membrane to drive it.
- this can also be a connecting rod actuated by a crank mechanism, or transverse slides, oscillating anchors or the like acting on the elastic wall parts.
- a kind of screw conveyor is used for the drive, the axis of rotation of which runs in the direction of flow and the outer flank which is effective during the drive attacks the membrane in a helical manner.
- the fixed boundary wall of the work space opposite the membrane is then concave towards the space, with inflow and outflow openings present at the beginning and end of this tunnel-shaped work space.
- the machine housing is tubular, the tube wall serving as a rigid wall part.
- two membranes are arranged parallel to one another in the machine housing, the drive being arranged between the membranes in a double-acting manner.
- the tubular housing has a circular cross section of the working space.
- the drive is carried out by at least indirectly transmitted magnetic forces. This type of drive can be particularly advantageous for smaller pumps in the medical or micropump sector.
- the magnetic forces or piezo forces are generated and also controlled electrically.
- moving electromagnetic fields for example, can be generated and moved in a simple manner via magnetic coils, as in a linear synchronous motor, and a membrane can thereby be driven.
- this can also be done by electromagnetic fields moving linearly or in curves.
- the overall system can also be designed analogously from chips through individual layers to close to hygroscopic limit values.
- the drive can be carried out using magnetic coils similar to loudspeakers or by means of a vibrating armature with the corresponding implementation of the movement.
- a conveyor machine of the type according to the invention namely in which the drive has a pulsating effect on the medium, so that a traveling wave is generated in the medium, can not only be implemented mechanically in a variety of ways, but also the field of application of this invention is correspondingly versatile. So the invention can be used in pumps in the large and medium performance range as well as in the micro range, in which wave-pumping foils can be used as elastic wall parts. The invention can also be used particularly in the field of medical microtechnology, namely where an axle drive is no longer available would be accommodable. Another area of application for compressors is from large machines to micro-designs.
- the "traveling wave” according to the invention results in a wobbling form of movement such as fish and snakes or the pumping movement of jellyfish, the basic drive being similar to in a propeller is caused by suction on the one hand and ejection on the other.
- the invention is used as a turbomachine. Just as sea elephants can be propelled on muddy or muddy ground, so it can also be used as a quasi amphibious vehicle in swamp areas, but possibly also on sand.
- the reverse application of the invention would be the floor of a trough in which the bulk material could be transported by the traveling wave-shaped drive of the floor - similar to vibratory transport on treadmills.
- an inflow opening in the bow and corresponding output opening in the stern and an output space located in between are provided in a ship's hull below the water level, the membrane facing the deck being able to be driven in a wide variety of ways.
- Two drive systems of this type can also be arranged next to one another, so that the ship can also be maneuvered depending on the different conveying capacity, or it can be a tube pump with a box arrangement as the boat drive laid out.
- the elastically movable wall part is designed as a membrane and clamped in the edge area, with the cross section of the membrane seen always a wavy contour remains, similar to the membrane of speakers.
- This prevents jamming when driving through the membrane of the clamping level since of course the cross section in the clamping area is smaller than in the extended area of the membrane, this clamping area must be covered by the same membrane as the extended area of the membrane where it is for example, against the fixed wall.
- the corrugated contour similar to the loudspeaker, enables high frequencies without disadvantage in terms of walking.
- hydraulically or pneumatically actuated profiles are incorporated into the membrane surfaces, as a result of which the membrane itself is able to continue to move in an undulating manner.
- elongated-flat and / or fibrous piezo elements are incorporated into the membrane as flexible profiles in order to deform them, for example for an inventive drive thereof.
- the deformation of flat parts by piezo elements is known in aircraft wings and helicopter rotors.
- Fig. 1 shows a cross section through a pump along the line I-I in
- Figure 3 is a partial longitudinal section along the line III-III in Figure 2.
- FIG. 5 greatly simplified a second embodiment in cross and longitudinal section and in different working positions; Fig. 6 shows a variant of the second embodiment; 7 an optimized membrane contour and FIG. 8 an application as a ship propulsion system.
- FIGS. 1 to 4 the invention is explained using a pump.
- a crank mechanism 2 is arranged in a pump housing 1 with an eccentric 4 arranged on a drive shaft 3 and a connecting rod 5 actuated by the latter.
- the connecting rod has in its upper region a cam 6 which is guided in a track 7 of the pump housing 1, so that the connecting rod 5 performs a tilting movement caused by the track 7 and the cams 6 when it is lifted and oscillated by the crank mechanism.
- the connecting rod 5 acts on a sliding block 8, which transmits the lifting pendulum tilting movement to a resilient plate 10 via a form-fitting support 9.
- the spring plate 10 thus follows not only the lifting movement of the connecting rod, but also its tilting pendulum movement in the area of the form-fitting support. This movement is transmitted from the spring plate 10 to a membrane 11, which is clamped in its edge region by beads 12 between the housing 1 and a housing cover 13. Between the membrane 11 and the housing cover 13, the pump working space 14 is enclosed, which is supplied with a medium to be conveyed via an inflow opening 15, which is then displaced from the pump working space 14 via an outflow opening 16.
- the pumping action is shown in FIG. 4 using six working positions:
- Inflow opening 15 are closed as outflow opening 16.
- the positive locking plate 9 is tilted to the left, as a result of which the membrane 11, transmitted from the spring plate 10, opens the inflow opening 15 to the pump work chamber 14, so that the medium to be conveyed flows in can.
- two mutually opposite delivery membranes 19 are arranged in a pump housing 20 which extends almost in the shape of a tube and are separated by a Conveying membranes 19 arranged camshaft 21 driven to generate a traveling shaft.
- the delivery of the medium which is indicated by arrows IV, takes place here in the longitudinal direction of the camshaft 21.
- the eccentrics 22 of the camshaft 21 each grip over a link 23, in the central opening 24 of which the eccentric 22 runs, as well as via a spring plate 25 on the conveyor membranes 19.
- the backdrop 23 is guided on tracks 26 of the housing 20.
- the traveling wave is not achieved by this guide, but rather by the assignment of the four cams in their successive effects on the membrane. Accordingly, the function is not linear. In any case, however, the use of two membranes achieves a quasi double-acting delivery, the two pumping spaces delivering slightly offset from one another due to the development of the cams.
- FIG. 5 the individual representations 5.
- Ibis 5.6 show different funding phases, which are described in more detail below. In each case there is an inflow opening at 27 and 28 and an outflow opening at 29 and 30, respectively.
- the pump work rooms are labeled 31 and 32.
- Inflow opening 28 of the pump work chamber 32 is largely open due to the relocation of the camshaft 21.
- the outflow opening 29 and the outflow opening 30, on the other hand, are open so that the medium to be conveyed can escape.
- the camshaft is rotated through 90 °, as a result of which the membrane 19 forces the medium to be pumped out of the pump work chamber 31 through the outflow opening 29 and, on the other hand, sucks it in via the inflow opening 27.
- suction is still sucked in through the inflow opening 28 during the conveying process in the middle Outflow opening 30 is ended because the membrane 19 abuts the pump housing 20 in this area.
- phase 5.6 in which the camshaft 21 had again turned through 90 °, the outflow opening 29 is closed and the inflow opening 27 is still open, so that the medium can flow into the pump work chamber 31 in accordance with the arrow V.
- the pump work chamber 32 conveys the medium to the outflow opening 30, while medium flows into this space via the inflow opening 28.
- Such a conveying device can also work with only one membrane with a correspondingly limited conveying capacity. It is thus also possible according to the invention to achieve a cascade-like delivery in which electromechanical drive systems are used instead of a camshaft.
- a cascade of several electromechanical transducers can be excited by a frequency generator, the generator having as many outputs as the transducers to be switched in the cascade.
- the outputs of the frequency generator are then 90 ° out of phase with each other.
- the cascade is operated in ascending order with an ascending phase.
- a propagating wave is generated with such an arrangement and the cascade of lifting systems supplied with it by means of an elongated membrane connected to it.
- FIG. 6 shows a variant of this second exemplary embodiment, in which only the pump housing 33 has a circular cross section, although the drive with camshaft 21 and the diaphragms 19 are designed as in the exemplary embodiment shown in FIG.
- the membrane 19 no longer reaches the wall of the pump housing 33, so that instead of being conveyed around with corresponding interruptions in conveyance, continuous conveyance takes place, as is typical in turbomachines.
- FIG. 7 uses functional lines to explain the design of membranes or rigid wall parts interacting with the membrane, which results in a minimum of flexing losses. This makes it possible to clamp the edge areas of the membrane in a non-displaceable manner.
- FIG. 7 the classic example of a work space is shown in FIG. 7, with an inner wall 34 which is slightly upwardly corrugated and a correspondingly outwardly curved membrane 35 which jointly delimit the work space 36 and asymptotically at its edge regions 37, on which the membrane is clamped approach.
- a kind of compression of the membrane takes place in its plane, which reaches its peak approximately on the line XII.
- the compression is related to the fact that the housing with the fixed wall 34 and the clamping points 37 are rigid, while the membrane 35 in its extended position requires a much larger clamping surface than in the position according to line IX.
- FIG. 7 shows the design according to the invention, in which the fixed wall 38 has a lip-shaped design, whereas the membrane 39 assumes a slightly curved shape in its extended, that is to say the lower, position. When it is pushed upwards, it passes through the center line X, whereby, as can clearly be seen, due to the undulating design, it no longer represents a forest problem.
- a constructive example is shown with a pump housing 40 and the membrane 39, which enclose the pump working space 36.
- the membrane 41 can be firmly clamped over beads 2 without a higher flexing work being expected or a separate load being created at the clamping points of the membrane 41.
- FIG. 8 shows an additional possible application of the invention, namely as a drive means for a ship.
- the representation is greatly simplified.
- a drive space 45 delimited by a membrane 44 is arranged.
- This drive space has an inflow opening 46 and an output opening 47.
- ambient water of the ship is sucked in via the inflow opening and repelled via the output opening after flowing through the drive space.
- Ship drives based on the displacement principle are of course known.
- the seal effect is advantageous here, so that propulsion would also be conceivable in the case of mud or mud, possibly also on non-sticky, flowing types of sand.
- Such a ship would have amphibian character under certain conditions, which would be advantageous in swampy areas.
- the membrane 44 can of course not be driven in the most varied of ways up to wind turbines above the ship, which could drive the membrane via a corresponding transmission.
- the membrane can be used to drive a ship, the membrane for conveying liquids, but also sludge, debris such as sand or the like, can take place according to the invention in reverse of the function, the membrane being able to form the bottom of an open channel and being driven accordingly is. All the features shown in the description, the following claims and the drawing can be essential to the invention both individually and in any combination with one another.
