Description

Technical Field

[0001] The invention relates to a transport device which is equipped with at least one ultrasonic generator and is designed for transporting powdery or granular material, and to an operating method for the transport device. Background Art

[0002] In production processes, in particular in the chemical industry, the building materials industry, the pharmaceutical industry and the food industry, the materials to be processed are transported and processed. Powdered or granular materials are dosed, mixed or sieved. In all these processes, materials and material components are conveyed or transported. These materials are therefore referred to below as process materials.

[0003] In screening equipment, the process material (e.g. a solid mixture) is separated into fractions with different particle sizes. The process material is fed to the screen and the fractions of different particle sizes obtained by screening are transported away. Therefore, the screening device is a transport device with a special function (i.e. screening function or separation function).

[0004] In a mixing device, the material components are mixed to form a mixed material. The components of the process material are supplied and the mixed material or the mixed process material is transported away. Therefore, a mixing device is a transport device with a special function, namely mixing.

[0005] In a dosing unit, the process material is dosed. The dosing unit is therefore also a transport unit.

[0006] The transport of process materials by means of transport devices is often accompanied by difficulties. Process materials transported along a partially open or closed transport frame may stick to the transport frame, form lumps, be unevenly distributed or transported unevenly. The transport frame is made of metal and surrounds or holds the process material so that it can be transported along or through the transport frame. The transport frame can be, for example, a channel, a pipe or a container. The transport frame can hold functional elements, such as a screen, which are used to process the process material.

[0007] This type of transport device often does not achieve the desired results in terms of efficiency and quality, for example when screening, mixing, batching or filtering. The separation or mixing of material components or the transport of process materials often does not take place with the desired quality, precision and / or output. The quality can be improved by adding consecutive processing stages. The output can be increased by larger systems or by connecting several systems in parallel. More complex systems allow for more precise batching.

[0008] It should also be noted that this type of transport unit generally requires a high level of maintenance. Process material can stick to the walls of the transport frame or clog the screen linings or filters, which must therefore be repaired or replaced at an early stage.

[0009] WO2018219840A1 describes a screening device with a screen, in which the vibration is transmitted to the screen lining via a screen frame or a transport frame to reduce the described problems. To this end, an ultrasonic generator is connected to the transport frame via a connecting rod. The ultrasonic waves reach the screen lining via the transport frame and can move the particles of the processed material so that, ideally, they do not adhere to the transport frame and the screen lining. In practice, improvements in this regard are particularly significant when sufficient ultrasonic power can be transmitted to the transport frame. It should be noted that it is generally undesirable to transmit high power because high temperatures will occur in the connection area of ​​the connecting rod to the transport frame, which can damage the connection point. Therefore, the effect of the coupled ultrasound is mainly carried out in the connection area of ​​the connecting rod to the transport frame, which is why its position should be selected accordingly.

[0010] It should also be noted that the connection of the coupling rod to the transport frame should only be achieved by properly trained personnel. If the connection is not optimal, the result will be unsatisfactory. In addition, a faulty connection will heat up and thus be destroyed when a higher power is applied. Summary of the invention

[0011] It is therefore an object of the present invention to provide an improved transport device having a sonotrode and a method for operating such an improved transport device.

[0012] According to the invention, a transport device is to be developed which is suitable for conveying and / or handling process material and, if necessary, is equipped for this purpose with one or more functional elements, such as a screen lining or a filter.

[0013] In the transport device according to the invention, the working processes for handling the process material (e.g. conveying and / or screening and / or filtering and / or mixing and / or distributing the process material) need to be improved. In particular, the quality and precision of these processes need to be improved. In the case of screening, a more precise separation is to be achieved; in the case of mixing, a better mixing is to be achieved; in the case of batching, a more precise quantitative delivery is to be achieved.

[0014] The conveying should be improved in such a way that a more uniform conveying and, if necessary, a more uniform distribution can be achieved. Preferably, the transport direction along which the process material is conveyed should be easily changeable. Preferably, it should be possible to deliver and convey the process material at selected points.

[0015] Additionally, the transport unit should increase production without expanding the system or adding more power.

[0016] The transport device should also be easy to assemble, so that already functioning systems and transport devices can also be further modified according to the invention.

[0017] Furthermore, the transport device should be easy and inexpensive to manufacture.

[0018] Furthermore, the maintenance work of the transport device according to the invention will be significantly reduced.Material adhesions, which lead to material losses, impair material quality and can interfere with the operation of the transport device, should be avoided not only at certain points but also over large areas.

[0019] A transport device for transporting powdered or granular processing materials includes an open or self-enclosed transport frame made of metal, which is configured to transport the processing materials. The transport frame is held by a supporting device and is connected to an ultrasonic device, which includes an ultrasonic generator, an ultrasonic transducer connected to the ultrasonic generator, and a connecting rod connected to the ultrasonic transducer, the connecting rod having a front end member and a rear end member.

[0020] According to the present invention, a flat distributor body made of metal is provided, which has an upper side, a lower side, a rear side and at least one connecting side of the periphery, wherein the rear end piece of the connecting rod is connected to the ultrasonic transducer, and the front end piece of the connecting rod is welded to the rear side, the upper side or the lower side of the distributor body, and at least one connecting side of the distributor body is integrally connected to at least one transport frame or at least one connecting side of the distributor body is welded to at least one transport frame.

[0021] The transport frame is usually at least partially made of metal so that the ultrasound is optimally transmitted from the distributor body to the transport frame. The transport frame that is closed in itself is, for example, a cone or a tube, which has, for example, a circular or polygonal cross-section, through which the process material passes. For example, an open transport frame is a flat or arbitrarily shaped plate or cover, on which the process material can be distributed. The closed or open transport frame can also have openings or holes and, for example, form a screen coating so that the process material can not only move along the transport frame, but also pass through the transport frame. Therefore, the transport frame can realize various functions, such as conveying and / or screening and / or separating and / or mixing and / or atomizing the process material. In order to realize these functions, the design and / or orientation of the transport frame can be changed in the conveying direction of the process material. For example, the diameter of the filter opening can change in the conveying direction. One process material or different process materials can be supplied to the transport frame at one or more points.

[0022] The distributor body is preferably in the form of a plate. The flat distributor body may have any shape in at least one dimension. The distributor body may be aligned in one plane or have any regular or irregular curvature or shape. Thus, the distributor body may be a flat plate or a flat geometric body, such as a cylinder or a portion thereof. The distributor body may also have any corrugations on the upper side and / or lower side and / or the front side or the rear side.

[0023] The distributor body transfers the ultrasonic energy introduced into the distributor body by the connecting rod to the transport frame along the elongated connecting cross section. The connecting cross section is, for example, rectangular, its height corresponds to the panel thickness, or has a continuous or uninterrupted irregular route. Therefore, the transport device according to the present invention can advantageously act on the processing material transported on or through the transport frame, and optionally process it, such as screening, mixing, acting with substances or changing its structure. The processing material exists, for example, in the form of powder or granules or in the form of a mixture of granules. By appropriate coupling of ultrasonic energy, the particles can be separated and more advantageously transported and processed. In particular, the transport direction can also be determined by the selective coupling of ultrasonic energy, so that the processing material is transported in one direction or evenly distributed. Instead of directly connecting the connecting rod to the transport frame and coupling the ultrasonic energy directly into the transport frame, the ultrasonic energy is coupled into the transport frame via the distributor body, which has many advantages.

[0024] At least one coupling rod and the distributor body can be made of the same or different metals, such as iron, steel, copper, aluminum or titanium. The coupling rod preferably has a circular or polygonal cross section and is inclined or perpendicular to the rear side, upper side or lower side of the distributor body with the associated end piece. The coupling rod is preferably curved or bent.

[0025] The spreader body is flat or extends along a flat or curved surface so that it is connected to the transport frame at the front along a strip or a corresponding cross-sectional course, which preferably has interruptions.

[0026] The distributor body can be a metal plate with uniform cross section or made of interconnected elements such as strip elements. The distributor body can also be a grid plate with strips.

[0027] In a preferred embodiment, the distributor body has corrugations so that the intensity with which the ultrasonic energy is coupled into the transport frame along the connecting side of the distributor body varies according to the corrugations, which results in turbulence and loosening of the transported process material particles.

[0028] The connection side is preferably formed by the usually relatively narrow front side of the plate-shaped coupling body and, if necessary, by the edge, since the front side alone is usually not sufficient to form a welded connection.

[0029] The distributor body acts as a transformer, which converts the incoming ultrasonic waves via the coupling rods, distributes them and couples them into the transport frame with increased amplitude. This transformation takes place on the difference between the coupling rods with a circular or polygonal cross section and the flat distributor body.

[0030] The connecting side of the flat distributor body is connected to the transport frame, optionally with gaps or recesses, so that the ultrasonic energy is coupled into the transport frame not at one point, but along a strip or cross section, depending on the thickness of the distributor body and the width of the weld.

[0031] By avoiding punctual coupling into the transport frame, punctual heating that could lead to damage to the connection points or welds is avoided. As a result, more energy can be coupled into the transport frame without fear of damage. The connection points extend on the connection side of the distributor body, which is why the heat energy generated by the welds or welds is absorbed by the transport frame on the one hand and by the transport frame on the other. Even when high powers are coupled, there are no overheating phenomena that could damage the connection area.

[0032] If the coupling rod is directly connected to the transport frame on time, which is associated with the above-mentioned disadvantages, there is a risk of damage. Therefore, the welding must be carried out with high quality by skilled personnel. The solution of the invention avoids this problem.

[0033] In the factory of the ultrasonic device manufacturer, the coupling rod and the distributor body can already be connected to each other with a high-quality connection. On the other hand, the connection or welding of the distributor body to the transport frame can be carried out by non-professionals without any problems. Along the connection side of the distributor body, a relatively long, possibly several-interrupted weld is produced, which ensures a strong connection between the distributor body and the transport frame. Even if part of the weld is not optimally executed, the entire weld ensures the desired connection quality. Therefore, non-professionals can also retrofit the distributor body connected to the coupling rod to an already installed system or transport frame. As a result, existing systems can be retrofitted in a simple manner.

[0034] It is particularly advantageous to use a transport frame which is integrally connected to one or more distribution bodies, which can be plate-shaped. The transport frame can, for example, be stamped out of a sheet of sheet metal together with the one or more distribution bodies and then bent. In this case, an optimal connection between the plate-shaped distribution body and the transport frame is produced. A welded connection between the transport frame and the distributor body is not necessary, which is why the transport device can be manufactured with less effort and at the same time with improved performance.

[0035] The transport frame can be connected to any support means in any manner. The transport frame can be screwed, welded or rigidly connected to the support means via mounting elements.

[0036] Preferably, the transport frame is connected to the supporting device via one or more non-metallic and / or elastic insulating elements. For example, the transport frame is connected to the supporting device via plastic screw fittings. Between the supporting device and the transport frame, insulating and / or elastic spacers or retaining elements, for example made of plastic or natural rubber, can also be arranged. The transport frame can also be suspended from the supporting device by insulating and possibly elastic ropes. The insulating elements insulate the transport frame mechanically and / or electrically from the supporting device. As a result, mechanical oscillations, vibrations or coupled ultrasonic oscillations are not absorbed by the supporting structure. As a result, the transport frame forms a vibration system that is only slightly damped and has an optimal effect at a relatively small energy input.

[0037] The ultrasonic energy can be coupled into the distributor body via one or more coupling rods. Furthermore, several distributor bodies, which can be supplied with ultrasonic energy via one or more coupling rods, can be connected to the transport frame. Thus, the ultrasonic energy can be advantageously transmitted to the transport frame as required. The ultrasonic energy can not only be advantageously distributed over the transport frame, but can also be transmitted to specific areas of the transport frame alternately or with selected intensities. The effect of the ultrasonic energy on the transport frame depends essentially on the design of the distributor body.

[0038] The transport device can have any transport frame for transporting powdery or granular processing materials. As mentioned above, an open or closed transport frame can be used.

[0039] A closed transport frame is, for example, a tube, a ring, a container, a funnel, a cylinder, through which the process material passes. An open transport frame is, for example, a channel along which the process material is conveyed or on which it is processed. The channel can be plate-shaped or, for example, have a U-shaped or V-shaped profile suitable for holding the process material. The transport frame is preferably integrated into the processing plant and adapted thereto.

[0040] By appropriate alignment, shaping, dimensioning and design of the distributor body, a corresponding coupling path of the ultrasonic energy and a corresponding action on the particles of the process material absorbing the kinetic energy are caused. Thus, by appropriate design of the distributor body and / or supply of ultrasonic energy through one or more coupling rods, various beneficial effects can be achieved.

[0041] The distributor body can be designed symmetrically so that a corresponding uniform coupling of the ultrasonic energy occurs along the connection side of the distributor body. On the other hand, the distributor body can also be designed asymmetrically so that a corresponding coupling path of the ultrasonic energy along the connection side of the distributor body is produced. The distributor body, which is preferably asymmetrical with respect to an axis extending perpendicularly to the transport frame, is preferably aligned in one or the other direction parallel to or oblique to the conveying direction of the process material.

[0042] The connection side and the rear side of the distributor body can extend parallel or obliquely to each other. The coupling along the connection side of the distributor body can be influenced by a corresponding course of the rear side of the distributor body or a corresponding asymmetric design of the distributor body.

[0043] By shaping the distributor body asymmetrically, it is possible to act on the particles of the process material in order to move them in one direction or the other.

[0044] The rear side of the distributor body may also have an undulating shape relative to the connection side of the distributor body, so that the intensity of the coupled energy undulates along the connection side of the distributor body.

[0045] A particularly good coupling into the transport frame is achieved when the spreader body is inclined or perpendicular to the transport frame.

[0046] The connection side of the distributor body is preferably parallel or inclined to the transport direction of the processed material. In a preferred embodiment, the connection side of the distributor body extends straight, so that, for example, a maximum effect is achieved in the transport direction. For example, the distributor body is aligned parallel to the longitudinal axis of the transport frame, for example a transport channel. In this case, the distributor body usually has a flat surface. It is also possible to realize a wave shape extending along a plane.

[0047] In particular for tubular or cylindrical transport frames, the connection side of the distributor body can also extend along a curve. For example, at least one distributor body is provided which completely or partially closes the transport frame in the form of a circle segment, annular segment or spiral.

[0048] In a preferred embodiment, the distributor body has coupling fingers separated from each other by gaps on the connection side. The coupling fingers can have the same or different sizes and cross-sections in terms of size or shape. Different degrees of coupling can be achieved by the design of the coupling fingers. For coupling fingers with a larger cross-section, a stronger coupling of the ultrasonic energy into the transport frame at the corresponding location is achieved. The smaller the cross-section, the lower the degree of coupling. For a circular cross-section, there is a more circular coupling with a corresponding depth effect, while for an elongated cross-section, the coupling of the ultrasonic energy occurs over a wider area along the transport frame.

[0049] A distributor body provided with coupling fingers at the periphery can also advantageously be used to distribute ultrasonic energy to several transport frames. At least one coupling finger of the distributor body is connected or welded to each transport frame.

[0050] The preferably symmetrical plate-shaped distributor body can also have a plurality of wings, each wing having at least one connecting side on the periphery. For example, the distributor body has a butterfly wing shape.

[0051] Furthermore, several distributor bodies can be welded to the transport frame, each distributor body being connected to the ultrasonic generator via at least one coupling rod and an ultrasonic transducer. The distributor bodies can be welded to the transport frame in the same or different planes, so that the desired effect of the ultrasonic energy occurs in one plane or in a volume portion between two planes.

[0052] By applying ultrasonic energy, typically in the frequency range of 25 kHz to 45 kHz, to the transport frame and associated functional elements, such as the filter lining, the particles of the process material are set in motion so that they can be conveyed more easily. Due to the applied kinetic energy, the particles cannot adhere to the transport frame or the functional elements and do not settle there. Due to the advantageous coupling with the aid of the distributor body, the ultrasonic energy can have a widely distributed effect on the transport frame and any functional units that may be present and prevents the particles of the process material from settling not only at specific points but also over large areas.

[0053] The process material is transported through or on a transport frame, for example by gravity or by a gaseous medium. The action of ultrasonic energy increases the throughput through the transport device without enlarging the equipment or adding more power. The particles of the moving process material can flow more easily and penetrate functional elements, such as filter linings, more quickly.

[0054] In a preferred embodiment of the invention, the particles of the processed material are acted on in a targeted manner by a specific release of ultrasonic energy and, if necessary, by a correspondingly designed distributor body, to move them as desired. The particles can be moved in a specific direction, distributed or released in a controlled manner. In addition, the particles can be moved, moved in a circle and rotated.

[0055] The ultrasonic energy is preferably transferred to the transport frame in such a way that the particles of the process material are transported in a certain direction, for example, optionally in the opposite direction, forwards or backwards. Thus, the process material can be selectively delivered to different points of the transport frame or of a functional unit held therewith. The process material can also be guided along a curve and, if necessary, circulated. For example, the process material can be conveyed upward along a channel that is inclined by up to 5° against gravity. In doing so, the ultrasonic energy can be used to act on various areas of the transport frame and any functional elements integrated therein. Thus, the process material can be conveyed in an advantageous manner, so that, for example, a uniform particle flow is generated.

[0056] By targeted supply of ultrasonic energy to convey particles of process material, not only can the process material be conveyed advantageously, but also the separation, sieving or mixing of particles with different properties (e.g. different size, different composition or different weight) can be improved. In addition, the filtration of process material in the filter unit can be optimized. In addition, accurate dosing is possible, especially in very small quantities. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] Figure 1 The transport device 1 of the invention in a preferred embodiment with a filter screen 2 is shown, comprising a transport frame 6 which holds a rectangular filter screen liner 21 and is connected via joints 312, 322, 332, 342 to the piston rods of four actuators 31, 32, 33, 34, which are connected via joints 311, 321, 331, 341 to a support device 10. The support device 10 comprises four columns connected to the actuators 31, 32, 33, 34, which are connected to each other via cross struts.

[0078] The actuators 31 , 32 , 33 , 34 are part of a drive device 3 , which also comprises medium lines 313 , 323 , 333 , 343 , through which, for example, electrical energy or hydraulic or pneumatic medium can be transmitted from a source 30 to the actuators 31 , 32 , 33 , 34 .

[0079] The transport frame 6 is also connected to an ultrasonic device 8, which includes an ultrasonic generator 80, which transmits ultrasonic energy to the transport frame 6 through an ultrasonic transducer 81, a coupling rod 82 and a distributor body 83. The ultrasonic generator 80 generates an alternating voltage electrical signal in the ultrasonic range of, for example, 25 kHz to 45 kHz. The alternating voltage signal is fed in the ultrasonic transducer 81 to, for example, a piezoelectric element, which is firmly connected to the coupling rod 82, for example, by a coupling strip. The alternating voltage electrical signal piezoelectric element converts into mechanical vibration and is transmitted to the transport frame 6 through the coupling rod 82 and the distributor body 83.

[0080] The transport frame 6 is rectangular and arranged so that the process material P can pass through it. The transport frame 2 holds a functional element, namely a screen lining 21. The screen lining 21 is preferably made of metal and is mechanically connected (preferably welded) to the transport frame 6. Therefore, the ultrasonic energy transmitted to the transport frame 6 can penetrate into the screen lining 21 and act on the process material P there.

[0081] The size and function of the transport frame 6 are selected according to the function of the transport device 1, which can be, for example, a feeding device, a screening device, a mixing device or a batching device. All these devices comprise a correspondingly designed transport frame 6, through which the process material is guided or on which it is stored and / or transported. Figure 1 In the embodiment of the transport frame 6, the transport frame 6 encloses a cross section through which the processed material P is guided. However, the transport frame 6 can also limit the transport path only on one side or on multiple sides, for example Figure 2a and 2b In addition, the transport frame 6 may have a minimum length required, for example for holding functional elements, such as the filter lining 21. Alternatively, the transport frame 6 may extend for a longer distance, for example several meters, as shown. Figure 3 shown.

[0082] It is essential that the ultrasonic energy can act on the process material P via the transport frame 6 and, if appropriate, at least one functional element in order to move it and, in particular, to prevent deposits on the transport frame 6 and the optional functional element.

[0083] The processing material P is a powdery or granular material, such as a powder or granules. The particles of the powder or granules may have the same or different compositions. The processing material P may have one or more components. For example, a processing material P consisting of several components is supplied as components and / or distributed in doses. The various components of the processing material P may also be supplied separately and mixed and / or distributed in a quantitative manner. The particles of the processing material P may have any chemical or pharmaceutical composition.

[0084] In order to control each actuator 31, 32, 33, 34 individually, the drive device 3 is connected to the control unit 100 via a communication line, in particular a control line 101, in which a control computer with an operating program is provided. The ultrasonic generator 80 can also be controlled via a control line 108. Preferably, the ultrasonic generator 80 is designed and controlled in such a way that an ultrasonic signal having a selected frequency within the ultrasonic spectrum of, for example, 25 kHz to 45 kHz can be selectively emitted. Optionally, the frequency can be scanned or continuously changed to avoid standing waves. In addition, the ultrasonic energy should be able to be selectively emitted at intervals.

[0085] The control unit 100 can also be supplied with measuring signals 511, 521 from sensors 51, 52, from which the process material P reaches the screen lining 21, and with the aid of status signals 109 from a feed device 9 (schematically indicated by an arrow pointing downward). The sensors 51 and 52 are optical sensors, for example imaging sensors, with the aid of which the distribution of the process material P that has reached the screen lining 21 is monitored.

[0086] The filter screen 2 can be subjected to almost any movement within the working volume by means of actuators 31, 32, 33, 34, for example linear drives with piston rods, controlled by the control unit 100. The screen 2 can be moved at least along its transport axis x and / or its transverse axis y, and / or rotated around an axis of rotation z which is preferably perpendicular to these axes x, y.

[0087] The actuators 31, 32, 33, 34 are preferably connected to the transport frame 6 and the support device 10 by ball joints 312, 322, 332, 342; 311, 321, 331, 341, which allow the actuators 31, 32, 33, 34 to rotate to a desired degree without restriction in any direction. When the piston rod of one of the actuators 31, 32, 33, 34 is extended, the other actuators 31, 32, 33, 34 can therefore rotate as required.

[0088] The actuators 31, 32, 33, 34 perform a coarse distribution. By providing ultrasonic energy, this coarse distribution is supported and a fine distribution also occurs. By the action of the ultrasonic energy, an air cushion is formed, through which the process material P can be distributed without resistance. The process material P is separated from the transport frame 6 and the functional elements or the filter lining 21 and cannot adhere to them. Therefore, there are no deposits that would lead to additional maintenance. On the other hand, under the influence of the ultrasonic energy, particles of corresponding size can quickly pass through the filter lining 21.

[0089] Therefore, if Figure 1As shown, the transport device 1 of the present invention may optionally include any mechanical drive and is not limited to supplying ultrasonic energy alone. However, in many cases, the ultrasonic energy provided by the present invention is sufficient to achieve the advantages of the present invention.

[0090] By coupling the ultrasonic energy via the coupling rod 82 and the distributor body 83 welded to the transport frame 6, the ultrasonic energy is coupled into the transport frame 6 along the connection side of the distributor body 83 rather than at a specific point. The problems caused by the conventional punctual coupling of ultrasonic energy are avoided. Even if high power is coupled, no damage is caused to the connection point. As described above, the distributor body 83 can be welded to the transport frame 6 in a simple manner, and the distributor body 83 is provided with the coupling rod 82 already welded thereto. The distributor body 83 acts as a transformer and couples the ultrasonic wave with increased amplitude into the transport frame.

[0091] The distributor body 83 can be welded to the transport frame 6 by non-professionals, such as pipes, conduits, containers, etc., even if the device is already installed and running. High temperatures at certain points are avoided. Instead, heat energy is preferably absorbed over the entire length of the transport frame 6 and the distributor body 83.

[0092] Figure 2a The transport device 1 of the invention is shown in a main embodiment with an ultrasonic device 8, which comprises an ultrasonic generator 80, which is connected to the transport frame 6 or a part thereof via an ultrasonic transducer 81, a coupling rod 82 and a distributor body 83. The coupling rod 82 is bent and its front end piece 821 stands vertically in the distributor body 83, preferably a metal sheet, and is welded thereto. In this case, the upper side 83U of the distributor body 83 forms a coupling side or transition piece 838, to which the coupling rod 82 is welded. However, if it is wide enough, the coupling rod 82 can also be connected to the lower side 83L or the rear side 83L of the distributor body 83.

[0093] The rear end piece 822 of the coupling rod 82 is connected to the ultrasonic converter 81, which has, for example, a coupling strip coupled to a piezoelectric element. Electrodes are arranged between the piezoelectric elements, and an AC voltage signal is applied to the piezoelectric element.

[0094] The distributor body 83 is symmetrical and has a connecting side 836, an upper side 83U and a lower side 83L. The connecting side 836 includes seven coupling fingers separated from each other by U-shaped recesses 830. The coupling fingers 831 are welded to the transport frame 6. The transport frame 6 is symbolically shown as a plate and can be configured in any way to receive and convey the process material P. The transport frame 6 can be, for example, a plate. The transport frame 6 can be, for example, a plate aligned at least approximately horizontally, on which the process material P is placed so as to mix, separate and / or distribute the process material P in a quantitative manner.

[0095] These processes are supported by a targeted supply of ultrasonic energy. For this purpose, a control unit 100 with a control program tp is provided, by means of which a control signal 108 is emitted to the ultrasonic generator 80 in order to emit an ultrasonic signal with a desired frequency and amplitude, possibly a sequence of ultrasonic signals, or a mixture of ultrasonic signals. As described above, the ultrasonic signal introduced into the distributor body 83 is amplified and transmitted to the transport frame 6 via the connection side of the distributor body 83 with an increased amplitude. The arrangement of the coupling fingers 831 and the intermediate recesses 830 makes it possible to act unevenly on the processed material P and to move and rotate it along almost the entire length of the transport frame 6.

[0096] Figure 2b Shows Figure 2a A transport device 1 having a transport frame 6 serving as a channel in the form of an upwardly open V-shaped profile. The transport frame 6 is preferably aligned horizontally or slightly inclined. Under the influence of large-scale ultrasound, the processed material P can move along the transport frame 6 as if on an air cushion. The transport frame 6 can thus form a transport channel that can extend in any direction.

[0097] Figure 2c A multi-bend distributor body 83 is shown. Figure 2b The distributor body 83 having four curved edges is connected at both ends to the transport frame 6 and one side 61, 62 of the channel formed by the transport frame 6 through the connecting side 836. The distributor body 83 is welded with two connecting rods 82 on both sides, through which high-power ultrasonic energy can be coupled into the transport frame 6.

[0098] Figure 2d The channel form Figure 2b The transport frame 6 is welded to distributor bodies 83A, 83B on both sides, and the distributor bodies 83A, 83B are anti-parallel and asymmetrical to each other. Via the two distributor bodies 83A, 83B, each of which is connected to the ultrasonic generator 80 via a coupling rod 82 and an ultrasonic converter 81, ultrasonic energy of any frequency and amplitude can be coupled into the transport frame 6 by the control unit 100 via one distributor body 83A or the other distributor body 83B or via both distributor bodies 83A, 83B.

[0099] Due to the asymmetric design and antiparallel alignment of the distributor bodies 83A, 83B, ultrasonic energy can be coupled into the transport frame 6 with a corresponding gradient. Therefore, depending on the type of coupling, the particles of the processing material P move in different ways and begin to move in one or another direction. If the coupling occurs antiparallel through the two distributor bodies 83A, 83B, the processing material P is rotated and conveyed depending on the inclination of the transport frame 6. However, if ultrasonic energy with different powers is coupled in through the distributor bodies 83A, 83B, movement in one or another direction is also possible. In this case, movement and turbulence can occur simultaneously. For example, the transport device 1 is used as a mixing device.

[0100] For example, the process material P can be dispensed first in direction A and then in direction b. Due to the type and variation of the ultrasonic energy coupling, a quantitative transport of the process material P in one or the other direction is possible. The material flow can be started and also stopped again. The intensity of the material flow can be controlled via the strength of the coupling.

[0101] Figure 2e Shows Figure 2d The transport frame 6 is integrally connected on both sides with symmetrically formed plate-shaped distributor bodies 83A, 83B. The transport frame 6 has been cut or punched out of a single sheet of metal and bent into the current shape. The distributor bodies 83A, 83B allow for optimal coupling of ultrasonic energy via several coupling fingers. The distributor bodies 83A, 83B can also have an asymmetrical shape with any orientation, so that all the functions described for the other embodiments of the present invention can also be realized. Conversely, the transport frame 6 of all other embodiments of the present invention can also be integrally connected to an optional plate-shaped distributor body 83.

[0102] The coupling of ultrasonic energy into the transport frame 6 is preferably carried out for example with reference to Figure 2d Proceed as described.

[0103] By way of example, it is shown that the transport frame 6 optionally comprises a first and a second filter layer S1, S2, which is achieved by having openings or boreholes of different diameters. Between the two filter layers S1, S2, a mixing zone is optionally provided, in which further process material Px can be fed. Thus, the process material P can be conveyed, screened or divided into a plurality of portions, mixed or loaded with further process material Px, screened or separated again and discharged. The fed process material P thus results in separated process material portions P1 and P2 and process material portion P3, which are discharged at the end of the transport frame 6. With the aid of a suitably designed transport frame 6, a variety of functions can be realized individually or in combination with each other.

[0104] The transport frame 6 is connected via mounting elements 691 to four rope-shaped insulating elements 69 , via which the transport frame 6 can be connected to the supporting device 10 . Figure 2d The transport frame 6 can be connected, for example, to Fig.11 The transport device 1 is used together with the transport device 1.

[0105] Figure 2f A distributor body 83 connected to a coupling rod 82 is shown, which has coupling fingers 831A, 831B, which are designed differently, separated from each other by a gap 830. In this way, any ultrasonic energy coupling mode can be generated, which is suitable for the process at hand, such as a mixing process, a separation process or a conveying process.

[0106] Figure 2f It is further shown that the coupling rod 82 may also be welded to the rear side 83R of the distributor body 83 .

[0107] Furthermore, it can be seen that the connection side 800 of the distributor body 83 is several times larger than the diameter of the coupling rod 82. This ratio may be within any range, such as 5-50 or more, in particular 10-25.

[0108] The coupling rod 82 and the transport frame 83 may be solid and have a closed cross section. Optionally, the coupling rod 82 and / or the distributor body 83 may also be provided with at least one through-channel or distribution channel 800. Several distribution channels 800 may be provided, which are connected to each other or extend separately from each other. Figure 2f , an optional through-channel or distributor channel 800 is shown, which passes through a portion of the coupling rod 82 and through a portion of the distributor body 83 to the coupling finger 831B. A metal connecting pipe 8200 is connected to the connecting opening 820, through which the liquid or gaseous medium M is introduced. Thus, the coupling rod 82 and / or the distributor body 83 and / or the transport frame 6 according to the invention can be provided with a separate channel or channel system, through which the transport frame 6 itself or the transported process material P acts. Figure 2f An example of a transport frame 6 with a distribution channel 600 of any shape is shown, to which the medium M is fed from a distributor body 83 which extends inside the transport frame 6 to an outlet opening and, if necessary, is fed to the process material P. The distribution channel 600 extending inside the transport frame 6 can also have a plurality of outlet openings, for example in order to mix or swirl the process material P with liquids or solids. Thus, the gaseous medium can carry powdered substances mixed into the process material P.

[0109] Figure 2g Shows Figure 2fThe distributor body 83 is connected to the ultrasonic transducer 18 via a coupling rod 82 and is used to convey a medium M, preferably a liquid or a gas, and is therefore completely or partially tubular or provided with a distribution channel 800. In the embodiment shown, the medium M, such as air, gas or liquid, can optionally be introduced through the ultrasonic transducer 18, if provided, and / or, if provided, can optionally be introduced into the coupling rod 82 through an opening 820 in the coupling rod 82 and guided through the distribution channel 800 of the distributor body 83 to an outlet on one or more coupling fingers 831B.

[0110] Therefore, in a preferred embodiment, the distributor body 83 of the present invention comprises one or more distribution channels 800, through which at least one medium M can be transferred to and / or into the transport frame 6. For example, a liquid medium can be supplied to the transport frame 6 through the first distribution channel 800 in order to cool it. A second medium M, such as a gas or a liquid, can be introduced into the transport frame 6 in order to mechanically or chemically influence the conveyed process material P. For example, the process material P can be rotated, impacted or mixed by the supplied medium M.

[0111] Figure 2g It is shown that the medium M is introduced into the coupling rod 82 through the opening 820 in the coupling rod 82 or through the ultrasonic transducer 81 and is conveyed via the coupling finger 831 B. A distribution channel 800 is shown by dashed lines.

[0112] The ultrasonic transducer 81 comprises an annular piezoelectric element 811, which is placed on a mounting shaft 812 and is clamped between flange elements 813, 814. The flange element 813 is, for example, a nut screwed onto the mounting shaft 812. A contact disc 8111 and / or an insulating disc 8112 are arranged between the piezoelectric elements 811. By applying an alternating voltage to the piezoelectric elements 811, preferably in the ultrasonic range, they are excited to mechanical vibrations. Thus, the ultrasonic vibrations are transmitted from the ultrasonic transducer 81 to the transport frame 6 via the coupling rod 82 and the distributor body 83. The mounting shaft 812 is provided with a transmission channel 8120, which axially passes through the mounting shaft 812 and thus through the ultrasonic transducer 81. Thus, the medium M can be applied to the inlet of the transmission channel 8120 and fed to the inlet of the tubular coupling rod 82.

[0113] In a preferred embodiment, the first medium M can therefore reach the first coupling finger 831B through the ultrasonic transducer 81 and the second medium M can reach the second coupling finger 831B through the opening 820 in the coupling rod 82 .

[0114] The distribution channel 800 can also advantageously be realized in a plate-shaped distribution body 83. For example, two complementary metal plates with a channel structure are connected to each other in such a way that the distribution channel 800 is enclosed between them and is connected to, for example, an access channel which is connected to a through-channel of the coupling rod 82.

[0115] Figure 3 A straight distributor body 83G welded to a first tubular transport frame 6A, a circular segment distributor body 83K welded to a second tubular transport frame 6B at different heights, and a spiral distributor body 83S welded to a third tubular transport frame 6C are shown. The spiral distributor body 83S is connected to a plurality of coupling rods 82 and allows ultrasonic energy to be coupled into the third tubular transport frame 6C along its entire length and circumference. The tubular transport frame 6 can be connected in any manner, for example, to the straight distributor body 83G and / or the circular segment distributor body 83K and / or the spiral distributor body 83S.

[0116] Figure 4 A transport device 1 is shown having a funnel-shaped transport frame 6 to which a distributor body 83 is welded.

[0117] Figure 5 The transport device 1 of the invention is shown with a tubular transport frame 6, to which a slightly upwardly inclined nozzle 69 is connected. Under the influence of ultrasonic energy, the process material P can be dosed through the nozzle 69. Kinetic energy is imparted to the process material P so that it can move slightly upwards and emerge from the nozzle 69. The dashed lines show that the distributor body 83 can be symmetrical or asymmetrical.

[0118] Figure 6 The transport device 1 of the invention is shown with an annular or cylindrical transport frame 6, into which a functional element, namely a screen lining 21, is inserted. The transport frame 6 is surrounded by an annular distributor body 83, into which ultrasonic energy can be coupled by six evenly spaced coupling rods 82A ... 82F, into the transport frame 6 and the screen lining 21. The control unit 100 outputs corresponding control signals 108A, 108B, 108C, 108D, 108E, 108F to the ultrasonic generator 80, so that ultrasonic energy can be applied to the transport frame 6 and the screen lining 21 with any gradient. Via the coupling rods 82A ... 82F, any constant or arbitrarily changing and moving energy pattern can be applied to the screen lining 21.

[0119] According to these energy gradients and energy patterns, the process material P moves and circulates in any direction on the screen lining 21. The movement of the process material P can be monitored by the optical sensors 51, 52 and reported back to the control unit 100 so that the control unit 100 can move and shift the process material P according to its program tp.

[0120] Thus, injection of ultrasonic energy extending along the gradient is possible not only by the asymmetric design of the distributor body 83, but also by the corresponding coupling of ultrasonic energy via the coupling rods 82A...82F.

[0121] Figure 7 A rectangular transport frame 6 is shown, into which the functional element or screen liner 21 is inserted and which is welded to the distributor bodies 83A, 83B, 83C, 83D at different heights on each side. The longer distributor bodies 83A and 83C are each welded to two coupling rods 82. The two shorter distributor bodies 83B and 83D are each welded to only one coupling rod 82.

[0122] Figure 8 The transport device 1 of the invention is shown with a distributor body 83, which is connected to a tubular transport frame 6 by means of a coupling device 84. The distributor body 83 couples ultrasonic energy into a coupling bar 841, from which the ultrasonic energy can be distributed to several transport frames 6. A tubular transport frame 6 is shown, which is connected to a connecting bar 843, to which ultrasonic energy can be supplied from the connecting bar 841 via a transmission bar 842.

[0123] By means of one or more transmission strips 842, the ultrasonic energy can thus be directed from the coupling strip 841 to several connecting strips 843 or directly to several transport frames 6. The dimensions and cross-section of the transmission strips 842 allow the energy flow of the ultrasonic energy to be adjusted as required.

[0124] Figure 9a A distributor body 83 is shown, which is connected to four cylindrical transport frames 6a, 6B, 6C, 6D via coupling fingers 831, into which cylindrical filter units 7 are inserted. Ultrasonic energy can thus be transmitted to different transport frames 6 via coupling fingers 831 forming connection sides 836 of the distributor body 83. One of the filters 7 is partially pulled out. In two of the transport frames 6a, 6B, the filter 7 has not yet been inserted. The device is arranged inside a container 60, for example.

[0125] This embodiment of the invention also demonstrates the advantages of the distributor body 83, which allows ultrasonic energy to be converted and distributed advantageously.

[0126] Figure 9bA transport frame 6B is shown. Figure 9a Distributor body 83.

[0127] Fig.10a A distributor body 83 is shown with two connection sides 836, each of which is connected to two cylindrical transport frames 6a, 6B; 6C, 6D, each of which is made from a single sheet of metal. The metal sheet can be pre-processed, for example provided with openings, and then bent to obtain the desired cross-section, for example circular, rectangular, triangular or polygonal. Between the two transport frames 6a, 6B; 6C, 6D, a connection piece remains, to which the distributor body 83 can be welded.

[0128] Fig.10b Shows Fig.10a The distributor body 83 has the shape of a butterfly with two wings, on each wing a connection side 836 is provided on the periphery. The distributor body 83 may also have additional wings, which preferably enclose equal angles with each other.

[0129] The connecting rod 82 is welded to the transition piece 838 between the two wings, and its end piece extends perpendicularly to the front or rear side of the plate-like distributor body 83. The end piece of the connecting rod 82 connected to the ultrasonic transducer 81 extends parallel to the axis in the middle between the cylindrical transport frames 6a, 6B; 6C, 6D. In this arrangement, the transport device 1 can be axially inserted into the tube or container 60 (see Figure 9a ). Therefore, the connection device 1 can be applied to any socket.

[0130] Fig.11 Shows that according to Figure 2e The transport device 1 of the invention comprises a transport frame 6 which is suspended from the support device 10 by means of four rope-shaped insulating elements 69. The transport frame 6 is suspended from the support device 10 and is insulated from the support device 10, thereby forming a virtually undamped vibration system, by which the processed material supplied from the supply device 9 can be optimally transported or conveyed.

[0131] By controlling the ultrasonic transducer 81 individually, preferably by means of the signal 188, the conveying process on the transport frame 6 can be controlled and the process material P can be distributed precisely. Due to the integral connection of the possibly plate-shaped distributor body 83 to the transport frame 6 and the floating mounting of the transport frame 6, which forms an oscillating system, the desired treatment of the process material P can already be achieved with low energy input. By means of appropriate control, the process material P can be acted on in a targeted manner in order to convey the process material P in a quantitative manner and, if necessary, to mix the process material P.

[0132] The feeder 9 located above the transport frame 6 includes an input channel 91 and an output channel 93, both of which are cut open and enclose the filter screen 2 between them. The filter screen 2 consists of a porous plate connected to the ultrasonic transducer 81 by a bent connecting rod 82. A rotor 95 driven by a motor 96 is rotatably held in the input channel 91, which pre-treats the process material P and / or feeds the process material P to the filter screen or screen 2.
