Definitions
- the invention relates to a separating device with a holding device by means of which a separating element, preferably a sieve, is held, and to an operating method for this separating device.
- intermediate products are often required which are present in particle form, ie "atomized" in the form of separate particles.
- the intermediate product can be precisely dosed and used efficiently. Incorrect dosages, which could cause undesirable taste, stabilization, financial or medical errors, are avoided.
- Bulk material can be required atomized in a uniform particle size or also in different particle sizes.
- Separating devices therefore allow particles of a bulk material to be separated from one another and, if necessary, also to provide the bulk material in a largely uniform particle size.
- the bulk material is transported from a starting position to a target position in which it should be in the desired shape. This transport usually takes place under the action of gravity, mechanical movements and, in screening technology, possibly also with the supply of ultrasonic energy.
- separating devices in the form of a sieve device comprise a sieve lining which, as a separating medium, contains a large number of openings of the same size.
- the size of the openings is called the mesh size. Larger grains remain above the openings (sieve overflow), smaller grains fall down (sieve passage).
- a grain that is roughly the same size as the mesh size is called a border grain.
- a sieve can consist of one or more sieve linings lying on top of one another, the sieve lining with the largest mesh size being on top in the sieve stack. For the efficiency of a sieve is The cleanliness of the screen lining is important.
- the clogging of the sieve openings by boundary grains must be carried out by suitable measures (e.g. brushes, balls, chains, rubber cubes that "run” on or under the sieve or by increasing the diameter of the holes downwards, e.g. with conical or double-cylindrical holes) be avoided.
- suitable measures e.g. brushes, balls, chains, rubber cubes that "run” on or under the sieve or by increasing the diameter of the holes downwards, e.g. with conical or double-cylindrical holes
- screen linings are excited by a drive to make certain movements to improve screening performance.
- the movement of the screen lining serves to transport the feed material further in the longitudinal direction of the screen, to eject the boundary grain from the mesh openings and to ensure the sustainability of the separation (screen efficiency).
- Tumbler screening machines are known (see e.g. EP0943374A2) which have a screen structure that can be brought into a tumbling movement (throwing and oscillating movement), a support device that elastically supports the screen structure, and an assembly shaft driven in rotation by an electric motor, which drives a sloping pin that is adjustable in inclination and eccentricity, on which the sieve structure is mounted.
- the screen lining is thus set in a predetermined and always the same movement by the assembly shaft and the inclined pin.
- Such systems are complex and cause considerable building vibrations and noise and require a relatively high level of maintenance.
- WO2018219840A1 describes a sieve device with a support device, by which a sieve is held, which has a sieve lining which is held by a sieve frame which is connected to a drive device.
- the Drive device which is controlled by a control unit, comprises at least three actuators, which are connected on the one hand via a first swivel joint to the support device and on the other hand each via a second swivel joint to the screen frame, so that the screen is held solely by the actuators and within a Working volume is displaceable and optionally rotatable.
- the screen lining is also preferably subjected to ultrasonic energy so that the screening process is accelerated.
- This separating device which delivers very good results, is also designed in a complex manner and requires a relatively large amount of space. The supply of the bulk material through a conveying container, however, is not easy or can only be implemented with great effort.
- a sieve device which has a sieve lining which is held by an outer frame and against which a metallic diaphragm rests, via which ultrasonic energy is transmitted to the sieve lining from an ultrasonic source.
- a sieve lining which is held by an outer frame and against which a metallic diaphragm rests, via which ultrasonic energy is transmitted to the sieve lining from an ultrasonic source.
- particles of the bulk material with a diameter smaller than the mesh size of the screen lining can pass through the screen lining more quickly as a sieve passage.
- Particles of the bulk material, the diameter of which is larger than the mesh size of the sieve lining are carried away to the outside as sieve overflow via the outer frame.
- This separating device with a sieve lining and a diaphragm resting thereon is also relatively complex.
- DE4448017B4 discloses a device for sieving, classifying, sifting, filtering or sorting dry solids or solids in liquids, with a sieve surface provided in a sieve frame and an ultrasonic transducer assigned to this, through which vibrations can be fed to the sieve surface.
- the ultrasonic transducer is assigned at least one resonator which rests on the screen surface and is tuned to the resonance of the ultrasonic transducer and can be set to oscillate by the latter. If the sieve is to be subjected to mechanical vibrations, it is built into a vibrating sieve machine, for example. Installation in a Vibrating screening machine causes correspondingly high expenses. Furthermore, the mechanical movements that can be exerted by the vibrating screening machine on the screen are limited in the forms of movement and only effective slowly.
- the present invention is therefore based on the object of creating an improved device for separating particles of a bulk material, which, using ultrasonic energy, allows particles of the bulk material to be separated from one another.
- the device according to the invention is intended to achieve better distribution of the bulk material on the separating element, such as a separating plate, more quickly using simple means.
- the particles of the bulk material should be able to be provided in different or similar particle sizes or in an at least approximately uniform particle size.
- an operating method for this improved separating device is to be specified, by means of which various processes, such as processes for loading, separating, mixing, ventilating, venting, unloading the bulk material, can advantageously be carried out. Furthermore, processes for cleaning and maintaining the separating device should be able to be carried out advantageously.
- the separating device should have a simple and compact design and can be maintained with little effort.
- the separation device should have a high efficiency and a correspondingly reduced energy requirement. Vibrations and shocks, as occur in known separating devices, should be avoided or significantly reduced without reducing the efficiency of the separating device.
- the bulk material should be able to be processed within the shortest possible path between a starting point and a destination in order to avoid bulky devices.
- the processed bulk material should be made available in high quality with a high degree of separation, so that incorrect dosages are avoided when using the processed bulk material.
- the separating device and supply channels and / or discharge channels should be designed largely independently of the type of bulk material and be able to be implemented with small dimensions. Residues of bulk material and corresponding changes in the cross-section of the transport routes, in particular dead zones, should be avoided during operation of the separating device.
- the operating method should allow optimal working parameters for the separating device to be set so that the bulk material present in each case can be optimally separated.
- the device which is used to separate particles of a bulk material, which can be supplied at an initial location and processed at a target location in different or similar particle sizes or in an at least approximately uniform particle size, comprises at least one separating element, which is a metal separating plate with openings provided therein has which can be acted upon with ultrasonic energy and is connected to an ultrasonic transducer and which is held by a holding device.
- the holding device is a mounting shaft which is fixed or movable, in particular rotatable and / or axially displaceable, at one end or at both ends, and which is connected at one end or at both ends to an ultrasonic transducer through which Ultrasonic energy can be coupled into the separating element via the assembly shaft, which is designed to be dimensionally stable.
- the mounting shaft is preferably provided with a contacting device.
- the contacting device preferably comprises slip rings and sliding contacts attached to them, via which AC voltage signals and / or DC voltage signals, possibly control signals, can be transmitted to the ultrasonic transducer or a control device provided there and / or an ultrasonic transducer connected to the assembly shaft, which in turn feeds the ultrasonic transducer.
- the ultrasonic transducer preferably has a piezoelectric transducer, which preferably comprises a plurality of piezoelectric elements.
- the piezoelectric elements are preferably clamped between two metal plates, which are positively or non-positively connected or welded to the assembly shaft, and connected jointly or individually to the ultrasonic generator by connecting contacts. Vibrations of the piezoelectric elements are transmitted via the metal plates to the mounting shaft and further to the at least one separating element.
- the metal plates can each be arranged as screw nuts on a thread of the mounting shaft. By tightening the nuts, the piezo elements are tensioned and at the same time there is an optimal connection between the nuts and the assembly shaft. It is also advantageously possible to use only one screw nut, by means of which the piezo elements can be pressed against a metal plate firmly connected to the assembly shaft.
- the mounting shaft can be made from one or more pieces.
- the mounting shaft is integral or connected to the motor shaft of the drive motor by a coupling.
- the piezoelectric elements are ring-shaped so that they can enclose the mounting shaft. This configuration results in a compact structure with maximum effect. Preferably five to twenty piezo elements provided.
- the piezo elements are preferably separated from one another by contact elements and, if appropriate, insulation plates.
- the piezo elements can be excited to vibrate by alternating voltages in the ultrasonic range, which vibrations are transmitted to the at least one separating element.
- the ultrasonic vibrations cause the particles of the bulk material to be detached from one another and to pass through the separating element if they have a correspondingly small diameter. Furthermore, it is prevented that a firm contact between the separating element and the bulk material results. The static friction and / or sliding friction and thus the frictional forces that result between the separating element and the bulk material are thus significantly reduced so that the bulk material is kept flowing and not blocked.
- any types of bulk material, homogeneous bulk material or non-homogeneous bulk material, as well as bulk material with any particle sizes can be processed.
- the bulk material can be subjected to processes in which it is thermally treated and / or ventilated and / or cleaned and / or its composition is changed.
- the separating plate can have a lattice structure or wire mesh structure, which is connected to the mounting shaft by at least one mounting element, such as a connecting sleeve or by at least two connecting rods that have the same or different diameters.
- the separating plate can be enclosed, for example, by a ring that is connected to the mounting shaft by the connecting rods or to a mounting sleeve that surrounds the mounting shaft.
- the separating element is held by a preferably centrally arranged assembly shaft and is designed to be dimensionally stable, larger assembly devices, in particular separating elements with a mounting frame, can be dispensed with. At the same time, there is the possibility of acting more directly and flexibly on the bulk material.
- the bulk material can optionally be exposed to any mechanical and acoustic effects in order to optimize the separation process.
- the separation process can also be carried out more efficiently with reduced energy consumption.
- At least one separating element or at least one separating plate can be subjected to any axial movements and rotary movements and any ultrasonic waves via the mounting shaft. If the bearing devices by means of which the assembly shaft is held are also rotatably mounted, further rotary movements can be carried out.
- the separating device Since the at least one separating element is not held peripherally, but rather centrally by the assembly shaft, the separating device is made more flexible.
- the connecting elements By avoiding connecting elements by means of which the separating element is connected peripherally, e.g. to a housing, with brackets or other assembly elements, the parts that are now independent of the separating element can be realized with higher degrees of freedom.
- the properties of the separating device can essentially be determined by the operating parameters of the control device, which is why the construction of the separating device requires less attention and effort.
- the partition plate can protrude, for example, peripherally between flanges, which form a seal with respect to a housing, for example, and ensure that bulk material can only pass through the partition element.
- the mounting of the mounting shaft can also be supported or replaced by mounting the separating element.
- the separating device 1 can be adapted to a bulk material and the objectives specified by the user with simple measures or the selection of operating parameters.
- the separating device according to the invention can thus optimally process different types of bulk material. For example, chemical powders, food particles, crystals, mechanical small parts and the like can be processed with the same separating device. If, on the other hand, the same bulk material is always processed, it is advisable to provide separating devices with appropriately adapted dimensions.
- the dimensions of the separating device and the separating elements can therefore differ from one another by orders of magnitude.
- the operating parameters, in particular the rotational speeds of rotatably mounted separating elements and switching frequencies, can differ from one another by orders of magnitude.
- the separating device including the supply channels and / or discharge channels can be designed largely independently of the type of bulk material with regard to the possibility of setting significantly different operating parameters.
- the cost of producing the separating devices is advantageously shifted from the structural level to the software level.
- the separating device has a simple but very flexible structure, which allows the implementation of new processes for treating the bulk material.
- the bulk material can be processed within a short distance between the starting point and the destination, so that separating devices according to the invention, which are provided for processing bulk material in the industrial areas mentioned, can generally be implemented with reduced dimensions.
- the separation of the particles can be carried out more efficiently not only in the area of the separating element or the separating elements, but over the entire transport path of the bulk material. Due to the flexibility of the separation device and the With a more advantageous effect on the bulk material, residues with changes in the cross section of the transport routes, in particular dead zones, are advantageously avoided.
- the optimal operation of the separating device can therefore be maintained over a longer period of time and the effort for maintaining the separating device is significantly reduced.
- the flexibilization of the separating device also enables at least partial self-cleaning of the device.
- the separating elements can be moved at the required speeds, for example to remove a sieve overflow.
- cleaning agents can be injected or sprayed in (see FIG. 4a), for example via the same channels via which work processes are influenced.
- the flexibilization of the separating device thus enables not only the optimal realization of the separating process, but also the realization of further processes, in particular mixing processes and cleaning processes.
- additional materials e.g. additional materials, substances and media can easily be fed in at any point or at any separation elements and / or intermediate processed bulk material can be removed.
- the bulk material can also be processed in a closed chamber under any gas pressure, possibly vacuum.
- the processed bulk material can be provided in high quality with a high degree of separation, so that incorrect dosing when using the processed bulk material is avoided.
- qualitative changes in the bulk material can occur in the work processes be made advantageous.
- a mixed material is optimally distributed and integrated into the bulk material.
- the separating element or the separating plate preferably forms a body of revolution.
- the partition plate has a basic structure and is, for example, flat, cone-shaped, helical, spiral-shaped, wave-shaped, helical, sawtooth-shaped or provided with steps or bevels.
- the partition plate is designed in the shape of a spherical wave.
- the ultrasonic waves can propagate particularly advantageously over the surface of the partition plate.
- At least one of the separating plates can also be provided with an additional three-dimensional surface structure which overlays the basic structure and which engages in the bulk material and can move it.
- a surface structure in the form of radially or inclined indentations or formations is preferably used, which are arranged at regular or irregular intervals.
- the partition plate can therefore have a first basic shape or basic structure which favors the uniform propagation of the ultrasonic waves and which is optionally overlaid by a surface structure which serves for mechanical interaction with the bulk material.
- the partition plate can have a uniform thickness or taper gradually or continuously from the center to the periphery, for example in the manner of a blade. In the thinned periphery, vibrations with a greater amplitude can develop. Otherwise, the dimensions of the partition plate are selected depending on the required strength with regard to the bulk material and the diameter of the partition plate.
- a material thickness in the range from 1 mm to 50 mm can be. If the separating plate tapers outwards, the material thickness can be reduced by 10-100 times exist.
- the diameters of the partition plates can range from 10 mm to 1000 mm or more. Again, the properties, in particular the specific weight of the bulk material, are decisive.
- Separation plates made of metal which conducts ultrasound, such as aluminum, steel, in particular stainless steel, copper, brass, titanium or an alloy, for example with such metals, are preferably used. Separating plates that are provided with a resistant protective layer, such as a noble metal layer, can also advantageously be used.
- the partition plate is made, for example, by primary molding from granular, powdery or liquefied material; by forming, such as rolling, forging, bending, pressing or deep drawing; by thermal ablation, such as spark erosion, die sinking, laser cutting; or by machining e.g. by turning, drilling, milling, grinding.
- the passage openings in the partition plates can also be realized by the processes mentioned.
- the diameter of the passage openings is e.g. in the range of 1 micron - 1000 micron for powdery bulk material.
- the diameter of the passage openings can be in the range of e.g. 1mm-15mm.
- the diameter of the passage openings of all separating elements can be the same size or also change gradually, so that the partition plate passing through first has the largest passage openings and the partition plate passing through last has the smallest passage openings.
- the separating element has a central axis and is designed to be rotationally symmetrical with respect to this central axis.
- the mounting shaft is preferably aligned coaxially or preferably only slightly eccentrically to the central axis of the separating element. If the assembly shaft is arranged eccentrically to the central axis, oscillations and vibrations result that facilitate the separation process.
- the partition plates are rotatably or displaceably arranged so that they are of a coaxial position can be rotated or shifted and fixed in an eccentric position. It is particularly advantageous that in this arrangement the at least one separating element can optionally be rotated in one direction or the other at a desired switching frequency and preferably optionally accelerated.
- the separating element can be connected to the mounting shaft in various ways.
- the partition plate comprises a mounting element in the form of a connecting sleeve or at least two connecting rods, which preferably have different diameters.
- four connecting rods with different diameters are provided crosswise.
- the coupling can advantageously take place, in particular in a circularly rotating manner. Standing waves are avoided or reduced. Instead, different waves are superimposed, which activates the entire surface of the partition plate.
- the one-piece or multi-part assembly shaft made of metal is elongated and preferably rod-shaped or cylindrical.
- the assembly shaft preferably has several shaft elements that can be connected to one another, each of which is connected fixedly or rotatably and optionally releasably to an associated separating element.
- the individual shaft elements can preferably be connected to one another in a form-fitting manner, screwed to one another or welded to one another.

- a cleaning liquid is then preferably introduced into the separating device, for example sprayed, in order to clean the separating elements.
- a gaseous medium such as air, can be admitted to dry the separating device.
- the separating device can therefore be transferred to a cleaning phase by the operating software, in which the separating device is returned to its initial state.
