Definitions
- the invention relates to a metering device for bulk goods according to the preamble of claim 1.
- Dosing devices are used in industrial or commercial application processes in which predetermined quantities of bulk goods are to be discharged, added or weighed per unit of time.
- the bulk goods are removed from a storage container with the aid of discharge or conveying devices and fed to the intended processes.
- the conveying devices are usually located below the storage container, so that the bulk goods usually get into the conveying device due to the gravitational effect. Problems can arise, in particular in the case of poorly flowing, adhering and bridge-forming bulk goods, with the continuous entry from the storage container into the conveying device. It is therefore often necessary for the metering devices to be equipped with agitators in the storage containers. Since the dosing devices should be cleaned or changes in the feed element are necessary in the event of servicing or when changing the bulk material, the discharge area of the dosing container must be accessible without great assembly effort.
- EP 0 486 424 discloses a metering device for dispensing bulk goods, which is made up of various structural units.
- the bulk container with horizontal agitator and output device form a structural unit that can be detached from the drives and the weighing part as a further structural unit without great assembly effort and can then be cleaned quickly and without a long interruption time. Because i -
- ACKNOWLEDGMENT QPIE he only has to remove the entire bulk container with the entire agitator and the discharge device for cleaning, this is only possible with smaller dosing devices, which for static reasons do not have to be installed in a stationary frame.
- a dosing device for bulk goods is known from DE 1S5 01 179, in which a separate intermediate container is arranged above a dispensing device, which contains a vertical agitator and can be detached from its drive and the dispensing device by a vertical plug connection.
- a dispensing device which contains a vertical agitator and can be detached from its drive and the dispensing device by a vertical plug connection.
- the agitator there is no connection between the agitator and a storage container which can be placed above it, so that the bulk material can adhere to the storage container or a separate agitator would have to be arranged there.
- a dosing device for bulk goods is known, which is part of a differential dosing scale.
- This differential dosing scale has a modular structure and is easier to access in service or Cleaning case equipped with laterally pivotable units under a permanently installed storage container, for example, a version for poorly flowing bulk goods is provided, in which a vertical agitator is arranged in the permanently installed storage container, which also extends to the bottom of an intermediate container, which can be removed
- a discharge device arranged under the intermediate container must then be released, which can then be pivoted laterally under the intermediate container
- the intermediate container can only be removed downwards, with a vertical expansion space being provided must, which corresponds approximately to the height of the intermediate container.
- Design variant is relatively labor intensive removable in service or re-narrowing case and does not require un ⁇ considerable vertical space.
- the invention is therefore based on the object of providing an easily accessible metering device which ensures a uniform flow of all bulk material through the bulk material container, and this with the simplest constructional means.
- the invention has the advantage that the use of a vertical agitator also makes it possible to reach the bottom and bottom areas of the rotationally symmetrical bulk goods container up to the discharge opening through the Ruhrwerk wing, so that no bulk material residues can become lodged or spoil. At the same time, a homogeneous bulk material flow can be achieved, since the uniform rotation of the agitator blade transversely to the direction of gravity detects all areas of the container in the same direction of force and thus influences the flow velocity evenly.
- the invention also has the advantage that the permanently installed agitator and container areas do not have to be dismantled with the aid of tools by the agitator coupling when cleaning or when servicing, so that longer downtimes of the metering device can be avoided.
- the discharge device with part of the bulk material container can be removed horizontally laterally by the agitator coupling, so that advantageously no additional vertical assembly space is necessary in the case of metering devices installed in the direction of gravity.
- the stirrer coupling enables the two stirrer parts to be operated with only one stirrer drive, so that a separate stirrer drive of the removable stirrer and container part can advantageously be dispensed with.
- the discharge device can be inserted horizontally in a fixedly installed ejector head, as a result of which the components that are susceptible to service and cleaning can be easily removed from the side of the metering device that is remote from the process without great assembly effort.
- Fig. 1 a side view of a metering device for bulk materials
- Fig. 2 a sectional view through a multi-part bulk container.
- FIG. 1 of the drawing shows a metering device with a two-part bulk container 2, a vertical agitator with a drive 1 and a discharge device 12, the lower container part with the vertical agitator part arranged therein being horizontally removable laterally.
- the two parts of the agitator are non-positively coupled and the lower part can be removed from the upper part.
- the upper part of the bulk goods container is designed as a storage container 8 which, in particular in the case of differential metering scales, must contain a predetermined supply between the refill phases.
- the storage container 8 is installed in a frame 9 of the metering device and is usually removable from it only with the aid of screw connections.
- a dosing container is attached as the lower container part, which is detachably connected to the storage container 8 via a clamp.
- a two-part vertical agitator is provided in the storage tank 8 and in the metering tank, which rotates about a vertical axis of rotation 7 inside the two tanks.
- This vertical agitator is driven by an electric motor 1 which is fastened to the storage container 8 by a screw connection.
- an angle gear 5 is arranged next to the electric motor 1, through which the agitator is driven at a relatively low speed of approximately 10 revolutions per minute [rpm].
- the vertical agitator in the storage container 8 can only be removed from this storage container 8 by dismantling the electric motor 1 and the angular gear 5 and a cover 6 of the storage container 8.
- the dosing container below the storage container 8 is conical like this and closed at the bottom by a horizontal cover plate.
- a slot-shaped outlet opening is provided in the base plate, below which the discharge device 12 is arranged.
- This discharge device is designed as a screw conveyor 12 which is fastened horizontally to the bottom of the metering container.
- the screw conveyor 12 consists of one or more metering screws, which are surrounded by one or two tubular walls and are driven by a separate electric motor 4.
- the discharge opening of the screw conveyor 12 mounts in a discharge head 11 to the side of the metering container.
- the discharge head 11 is designed as a T-shaped piece of pipe and is attached to the frame 9 of the metering device via a fastening strut 10.
- the horizontal opening of the discharge head 11 has emgescnoben the discharge tube of the screw conveyor 12 and sealed airtight and dustproof by means of an elastic seal.
- the drive motor 4 of the screw conveyor 12 is connected via a vertical swivel arm 3 to the frame 9 of the metering device.
- the drive motor 4 can be uncoupled from the metering screw by a special coupling by pivoting.
- the dosing container can then be removed laterally under the storage container 8.
- only the tension lock of the tensioning clamp has to be loosened and the dosing container with the dosing cutter can be pulled out of the discharge head 11 laterally. Since the discharge head 11 m is usually connected to a pipe system, not shown, through which the process-carrying debris is transported, the cleaning and service work can advantageously be carried out from the side facing away from the process, without the process supply connections being expensive to disassemble.
- the storage container 8 and the dosing container 30 with the two parts of the vertical agitator 19, 22 are shown in section.
- the storage container 8 arranged above the metering container 30 and tapering conically downwards contains a mechanically separate agitator part 22 which is driven via a vertical central axis 23.
- the vertical central axis 23 is arranged vertically, but can also be oriented inclined in the case of inclined conveyors or other designs.
- the Ruhrwerk part 22 of the reservoir 8 consists essentially of two Ruhrwerk flights, which are firmly connected to the vertical central axis 23.
- the wings are formed from two horizontal arms 13, 24, which are connected to two cross struts 14 arranged parallel and close to the inner surface of the container.
- a horizontal arm 13 is arranged in the area of the upper container cover 6 and a further horizontal arm 24 is located close to the lower end of the storage container 8.
- the vertical central axis 23 extends through the reservoir 8 from the angular gear 5 to the lower end of the reservoir 8.
- the central axis 23 is mounted on the top of the angular gear 5.
- the intermediate ring 26 consists of a central part with a bore and an outer ring of the size of the container diameter and arranged in between
- the intermediate ring 26 is arranged between the two containers 8, 30 and is fixed in position by a clamp 17 m.
- the intermediate ring 26 is used for centering and mounting the two coupled parts of the Ruhrtechnik 19, 22nd
- the dosing container 30 arranged below the storage container 8 is also conical and tapering downwards, the upper diameter of the dosing container 30 corresponding to the lower diameter of the storage container 8.
- the do- sier container 30 is open at the top and closed at the bottom by a base plate 29, although an outlet opening is provided in the base plate 29. Through the outlet opening the flowing bulk material passes into the dosing container 30 arranged underneath the screw conveyor 12, which discharges the bulk material metered by ei ⁇ ne controlled speed in the dropping head. 11
- a separate vertical agitator part 19 is also provided in the reservoir 30, which represents the continuation of the agitator part 22 in the reservoir 8 and is of comparable design.
- the lower Rhaktechniksteil 19 also consists of a second central center axis 28 of the Vorratsbehalters is ordered to 8 ⁇ in the extension of the center axis of the 23rd
- a further horizontal arm 18 is provided at the top and a horizontal arm 20 in the area of the base plate 29.
- These two horizontal arms 18, 20 are also connected to one another by two cross struts 27 in the region of the container walls.
- the second central axis 28 is supported at the bottom on a bearing element which is connected to the base plate and at the top in the intermediate ring 26.
- a coupling arm 25 is arranged above the intermediate ring 26 and is non-positively connected to the second central axis 28 of the lower agitator part 19. For this purpose, a square fit is provided on the central axis 28 above the intermediate ring 26, onto which the coupling arm 25 can be plugged with a corresponding opening.
- the coupling arm 25 extends over a length that is not greater than the horizontal arms 24, 18 of the agitators 19, 22 at the junction of the two containers 8, 30, but as large as possible than half the diameter of the dosing container 30 in this plane.
- the coupling arm 25 is angled vertically upwards at both ends, as a result of which two driving pins 16 are formed, which engage the rotation range of the horizontal arm 24 of the upper rotating flywheel in the installed state m.
- the horizontal arms 24 strike these driver pins 16 and thereby take the lower part of the wing of the Ruhrwerk with them and thus form a positive coupling between the two parts of the Ruhrwerk.
- the driving pins 16, which rotate in the bulk material flow cannot become clogged and cannot be specifically aligned when the dosing container 30 is inserted under the storage container 8, and the dosing device can therefore also be easily put together again without special fits for it Direction of rotation not correct.
- the coupling arm 25 has an additional agitation effect, so that the homogeneous flow of the
- the coupling arm 25 could, however, also be attached to the upper rotary wing and, with its driving pin m, engage the rotary region of the lower part of the Ruhrwerk 19.
