Description

DISPENSING APPARATUS FOR PACKAGING A MATERIAL

FIELD OF THE INVENTION

The invention relates to a dispensing appa- ratus for packaging a material as defined in claim 1, and to the use defined in claim 14.

BACKGROUND OF THE INVENTION

Various sacking devices for packaging differ- ent types of materials by sacking are known in the prior art. In some materials, their internal friction changes under pressure due to the moisture contained in the material, causing compaction, sticking and bridging of the material in the sacking device. This renders packaging of the materials difficult.

OBJECT OF THE INVENTION

The object of the invention is to disclose a new apparatus for packaging a material. A further ob- ject of the invention is to disclose an apparatus to facilitate handling and packaging of unwieldy materials, such as sticky materials and precipitate.

SUMMARY OF THE INVENTION

The dispensing apparatus according to the invention is characterized by the features set forth in the claims.

The dispensing apparatus comprises at least a vertical and downwardly tapering hopper element in which the material being dispensed is arranged, com^¬ prising more than two side walls with corners there^¬ between, at least two elongated plate-shaped parts at^¬ tached substantially horizontally in connection with at least two side walls of the hopper element, e.g. to the outer surface or alternatively to the inner sur- face of the side wall, so as to extend substantially from one corner of the hopper element to another, and a dispensing element arranged, such as connected, to the tapering end of the hopper element, through which dispensing element the material is dispensed, prefera^¬ bly from the hopper element into a package, and at least one vibrator arranged in connection with the hopper element to provide vibration of the hopper ele^¬ ment via the elongated plate-shaped part to the side walls of the hopper element. The apparatus may be used for handling unwieldy materials, e.g. sticky materials and precipitate. The apparatus may be used as a mate^¬ rial packaging apparatus, e.g. as a sacking apparatus.

In this connection, the material being dis- pensed refers to any material being dispensed, such as material being sacked, containing one or more material components. The material may comprise unwieldy and sticky materials, such as concentrates, or precipitate, such as precipitate produced when processing nickel, zinc, copper, vanadium or the like. Further, the material may also comprise other material components.

In one embodi^¬ ment the hopper element comprises four side walls and corners therebetween, and two elongated plate-shaped parts are arranged at opposite side walls of the hop- per element substantially horizontally from one corner to another. In one embodiment the hopper element com^¬ prises six side walls and corners therebetween, and three elongated plate-shaped parts are arranged at every other side wall of the hopper element substan- tially horizontally from one corner to another. When the elongated plate-shaped parts connected with the vibrator or vibrators are arranged at opposite side walls or every other side wall of the hopper element, the force provided by the vibrator or vibrators may be distributed via the corners evenly to the whole area of the side walls of the hopper element. In one pre^¬ ferred embodiment the elongated plate-shaped parts are arranged at the outer surface of the side walls of the hopper element. In one alternative embodiment the elongated plate-shaped parts are arranged at the inner surface of the side walls of the hopper element. The elongated plate-shaped parts may be attached to the side walls of the hopper element by any appropriate manner, e.g. by welding, bolting, screwing or other suitable way.

In one embodiment the elongated plate-shaped part is formed from metal, e.g. steel, composite mate^¬ rial or other suitable material that withstands me^¬ chanical movement. In one embodiment the elongated plate-shaped part may be an element of any shape or width and any thickness, preferably extending substantially horizontally over one side wall from one corner of the hopper element to the next. In one embodiment the height of the elongated plate-shaped part is 5 - 30 %, in one embodiment 10 - 25 % and in one embodi- ment 15 - 23 %, of the height of the side wall of the hopper element. In one embodiment the thickness of the elongated plate-shaped part is 3 - 5 mm.

In one embodiment the outer surface of at least one, preferably more than one of the side walls of the hopper element is provided with at least one support, e.g. a substantially horizontal angle iron, to which a protective element, such as a plate, e.g. a rubber plate, is arrangeable or connectable to prevent the material being dispensed from being scattered out- side the hopper element during filling of the hopper element .

In one embodiment the outer surface of at least one, preferably more than one of the side walls of the hopper element is provided with at least one bracket, projection or fastener on which the hopper element rests or by which it is attachable to the dis^¬ pensing apparatus or to an assembly including the dis^¬ pensing apparatus, or by which the hopper element is liftable .

In one embodiment the dispensing element com^¬ prises at least a reducer element. In one embodiment the dispensing element comprises a reducer element and a dispensing mouth element.

In one embodiment the reducer element is a downwardly tapering, conical element comprising at least four walls with corners therebetween. Preferably the reducer element is arrange- able in the dispensing apparatus between the hopper ele- ment and the dispensing mouth element. The reducer ele^¬ ment of the dispensing element may be any appropriate device component that is tapering and that is preferably connectable with the dispensing mouth element.

Preferably the reducer element is shaped such that the cross-sectional profile of the upper part of the reducer element corresponds to the cross-sectional profile of the tapering end of the hopper element, e.g. a rectangle or a quadrangle, and the cross-sectional profile of the lower part of the reducer element corre- sponds to the cross-sectional profile of the dispensing mouth element, e.g. a circle. In one embodiment the dispensing mouth element is shaped to be, in cross- section, substantially circular, or alternatively of a selected polygonal, e.g. tetragonal, pentagonal or hex- agonal, shape. In one embodiment the reducer element is shaped so as to taper such that the inner surface of the reducer element has no projections or other such uneven- ness of the inner surface to provide obstructions of flow of the material stream, and so as to provide a good and smooth flow of the material being dispensed without the material sticking at the inner surface of the reduc^¬ er element and without bridging. In one embodiment the reducer element is shaped so as to taper such that the angle of its longer walls is 38 degrees and the angle of its shorter walls is 19 degrees, wherein the angles are measured from the vertical line. Further, preferably the connection between the hopper element and the reducer element of the dispensing element is shaped such that the connection is free of corners or notches that would cause bridging of the material. This way, the material being dispensed may be dispensed smoothly from the hop^¬ per element into packages through the dispensing ele^¬ ment, and bridging may be prevented.

In one embodiment, at least one wall of the re^¬ ducer element comprises an opening for a sampling device or another monitoring device. The opening may be closa- ble, in case the sampling device or another monitoring device is not used. In one embodiment the lower part of the reducer element is provided with a connecting means, e.g. a collar or a flange, to facilitate connecting the reducer element to the dispensing mouth element.

In one embodiment the material being dis^¬ pensed is arranged into the hopper element of the dis^¬ pensing apparatus by feeding it with a feed device. The feed device may have been selected from feed de^¬ vices known per se, such as a feed screw, a pipe, a scoop, another feed device and their combinations.

The hopper element and the dispensing element may be any suitable elements. The hopper element and the dispensing element may have been formed from any suitable material. In one embodiment the hopper ele- ment and the dispensing element are formed from the same material. In one embodiment the hopper element and the dispensing element are formed from different materials. In one embodiment the hopper element and/or the dispensing element are formed from metal, such as steel, or a composite material or their combinations.

In one embodiment the dispensing apparatus com^¬ prises one vibrator. In one embodiment the apparatus comprises more than one vibrator. In one embodiment, one vibrator is connected with more than one of the elongated plate-shaped parts. In one embodiment the apparatus comprises an equal number of vibrators and elongated plate-shaped parts for providing the vibra^¬ tion such that one vibrator and one elongated plate- shaped part constitute their own assembly for provid^¬ ing the vibration. The vibrator may be any appropriate vibrator known per se for providing the vibration and for facilitating the flow of the material being dispensed in the dispensing apparatus. In one embodiment the vibrator is a mechanically or electrically adjust^¬ able vibrator.

In one embodiment the vibrator is connected with the elongated plate-shaped part. In one embodi^¬ ment the elongated plate-shaped part comprises at least one connecting piece for connecting the vibrator with the elongated plate-shaped part. In one embodi- ment the vibrator is attached onto the elongated plate-shaped part by means of the connecting piece. In one embodiment, connecting the vibrator with the elongated plate-shaped part is done by a bolted joint.

In one embodiment the dispensing apparatus comprises at least one sampling element for taking a sample from the material flow. In one embodiment the sampling element is arranged to take samples continu^¬ ously. In one embodiment the sampling element is a sampling screw. In one embodiment the sampling element is a sampling screw in which the size of the sample is adjustable. In the sampling screw, the size of the sample is adjusted by the rotational speed of the screw, and the sample is conveyed through a tube into a sampling container. Taking the sample from the material flow with the screw ensures that the sample is representative, and the size of the sample is easily adjustable. In one embodiment the sampling screw is arranged substantially centrally in the hopper ele^¬ ment. In one embodiment the outlet of the tube of the sampling screw is arranged at the wall of the reducer element.

In one embodiment the dispensing apparatus comprises a holder for supporting the package being filled. The holder may be any holder, hook, hook system or other such means for supporting the package, such as a sack, preferably during filling.

In one embodiment the dispensing apparatus comprises a weighing device for weighing the package during dispensing, such as filling. In one embodiment the weighing device is arranged to weigh the package in real time. In one embodiment the weighing device is an electronic weighing scale.

In one embodiment the dispensing apparatus comprises a signalling means, e.g. a light beacon, for outputting a signal based on which the material dis- pensing process may be started or stopped. In one em^¬ bodiment the signalling means is arranged to co^¬ operate with the weighing device.

In one embodiment the dispensing apparatus is arranged to be batch-operated. In one embodiment the apparatus is arranged to be continuously operated. In one embodiment the dispensing apparatus is a movable apparatus. In one embodiment the apparatus further comprises a container inside which an assembly formed by the hopper element and the dispensing ele- ment is arrangeable. The container may be any contain^¬ er, e.g. a sea container, or a container-type struc^¬ ture that is easily movable. Thus, an easily movable dispensing apparatus may be formed, and it may be brought to the material being packaged.

The dispensing apparatus according to the invention may be used in various applications where it is necessary to handle materials being dispensed, preferably unwieldy and/or sticky materials or precip^¬ itates. The apparatus according to the invention may be used for handling and dispensing industrially pro^¬ duced materials, such as bulk materials. In one embod^¬ iment the apparatus according to the invention may be used for handling bulk materials produced in extrac^¬ tive industry, e.g. nickel, zinc, copper and pyrite concentrates and precipitates. Especially the materi^¬ als produced in concentration processes are often sticky due to moisture and chemical residues.

By means of the invention it is possible to handle and dispense, such as sack, various materials that may also include unwieldy components in terms of dispensing and sacking. With the invention, the force of vibration can be evenly distributed in the hopper element. When the elongated plate-shaped part is ar^¬ ranged to extend, at least in some of the side walls of the hopper element, from one corner to another, the force from the vibrator can be directed to the cor^¬ ners, and thereby distributed evenly in the hopper el^¬ ement, so that the hopper element as a whole will move. Consequently, vibration may be achieved with less force. This way the hopper element is subject to less pulling movement, and for example the interior coatings of the hopper element experience less stress. By means of the invention it is possible to handle and dispense various materials efficiently and economical^¬ ly.

The dispensing apparatus according to the invention may be produced cost-effectively. The device components needed for the apparatus of the invention are simple, and their manufacture and servicing is easy.

DETAILED DESCRIPTION OF THE INVENTION

The invention will now be described by way of detailed examples of its embodiments, with reference to the accompanying figures.

Example 1

Fig. 1 - 3 illustrate a sacking apparatus for packaging unwieldy materials, such as sticky materials and precipitate, into sacks.

The apparatus comprises a vertical and down^¬ wardly tapering and conical hopper element (1) in which the material being dispensed is arranged, com^¬ prising four side walls with corners therebetween. The cross-section of the hopper element, as seen from the top, is rectangular. Further, the apparatus comprises two elongated plate-shaped parts (4) attached by weld- ing substantially horizontally to the outer surface of two opposite side walls so as to extend on the side wall from one corner of the hopper element to another. Further, the apparatus comprises a dispensing element that comprises a reducer element (2) and a dispensing mouth element (3) and that is connected with the taper- ing end of the hopper element (1) by means of the re^¬ ducer element, through which dispensing element the material is dispensed from the hopper element into a sack. Further, the apparatus comprises at least one vibrator connected with the elongated plate-shaped part to provide vibration of the hopper element via the elongated plate-shaped part (4) to the side walls of the hopper element. The vibrator may be any appro^¬ priate vibrator known per se, which is not shown in the figure.

Each elongated plate-shaped part (4) compris^¬ es at least one connecting piece (5) for connecting the vibrator with the elongated plate-shaped part. In this case, the vibrator is connectable and attachable onto the elongated plate-shaped part (4) by a bolted joint.

Coating panels, e.g. polyethylene or polypro^¬ pylene based panels, are attached to the inner surface of the side walls of the hopper element (1) to form an interior coating (7).

Because the hopper element (1) comprises four side walls and corners therebetween, as well as two elongated plate-shaped parts (4) arranged at opposite side walls of the hopper element substantially hori^¬ zontally from one corner to another and connected with the vibrators, the force provided by the vibrators may be distributed via the corners evenly to the whole ar^¬ ea of the side walls of the hopper element.

The reducer element (2) is shaped such that the cross-sectional profile of the upper part of the reducer element corresponds to the cross-sectional profile of the tapering end of the hopper element (1), in this case a quadrangle, and the cross-sectional profile of the lower part of the reducer element corresponds to the cross-sectional profile of the dispensing mouth element (3), in this case a circle. The cross-section of the dispensing mouth element (3) is circular.

The hopper element (1), the reducer element (2), the dispensing mouth element (3) and the elongated plate-shaped parts (4) are in this example formed from steel .

The dispensing apparatus comprises a sampling screw in which the size of the sample is adjustable. The sampling screw is arranged substantially centrally in the hopper element (1), and the outlet of the tube of the sampling screw is arranged in an opening (6) at the wall of the reducer element (2) .

Further, the outer surface of more than one of the side walls of the hopper element (1) may be provided with a substantially horizontal angle iron (11) to which a protective element, e.g. a rubber plate, is arrangeable and connectable to prevent the material being dispensed from being scattered outside the hopper element during filling of the hopper element .

Further, the outer surface of more than one of the side walls of the hopper element (1) may be provided with projections (8,9) by which the hopper element is liftable and on which the hopper element rests in the dispensing apparatus or in a container housing the dispensing apparatus.

Example 2

Fig. 4a and 4b illustrate a reducer element of the dispensing apparatus for preventing sticking and bridging of the material being dispensed.

The reducer element (2) is a downwardly taper^¬ ing, conical element comprising four walls with corners therebetween. The reducer element (2) is arrangeable in the dispensing apparatus between the hopper element and the dispensing mouth element. The purpose of the reducer element (2) is to be an adapter between two elements with different shapes and to enable the material to con^¬ tinue flowing undisturbed in this intermediate space. The reducer element (2) is shaped such that the cross- sectional profile of the upper part of the reducer ele^¬ ment preferably corresponds to the cross-sectional pro- file of the tapering end of the hopper element, e.g. a rectangle or a quadrangle, and the cross-sectional pro^¬ file of the lower part of the reducer element corre^¬ sponds to the cross-sectional profile of the dispensing mouth element, e.g. a circle. In this example the reduc- er element (2) is at the upper part, in cross-section, quadrangular, and at the lower part circular. Preferably, the reducer element (2) is shaped so as to taper such that the inner surface of the reducer element has no projections or suchlike unevenness on the inner sur- face to provide obstructions of flow of the material stream, and so as to provide a good and smooth flow of the material being dispensed without the material stick^¬ ing at the inner surface of the reducer element and without bridging.

At least one wall of the reducer element (2) comprises an opening (6) for a sampling device. The opening (6) may be closable, in case the sampling device is not used.

The lower part of the reducer element is pro- vided with a collar (10) that serves as a connecting means to facilitate connecting the reducer element to the dispensing mouth element. Example 3

In this example, unwieldy and sticky material produced in extractive industry was sacked with the sacking apparatus described in Example 1.

The wall thickness of the hopper element was

4 mm, and its material was S355 steel. The thickness of a plastic throughout-slippery coating panel was 10 mm. The thickness of the elongated plate-shaped part attached by welding to the side wall on the outer side of the hopper element was 10 mm, and its height was 1/5 of the height of the hopper element.

The thickness of the point of attachment of the vibrator was 10 mm + 20 mm on the elongated plate- shaped part, and it was fastened by bolts. The tech- nical specifications of the vibrator were: static force 30 kg/mm, 50 Hz, 2.98 kN, 3000 rpm and 1.04/0.6 amplitudes .

The dimensions of the sampling screw were: screw diameter 68 mm, tube inner diameter 72 mm and outer diameter 76,1 mm, screw wave length 68 mm and shaft thickness 30 mm. The measures for the sampling tube hole were: length 0 - 200 mm and width 72 mm. The screw is powered by an electric motor, and the rota^¬ tional speed of the screw was 10 - 100 rpm.

It was noted that sticky material could be handled and sacked easily with the apparatus according to the invention without sticking of the material. It was noted that when using the elongated plate-shaped part according to the invention arranged at the outer wall of the hopper element to extend horizontally from one corner to another, the force of vibration could be distributed in a satisfactory way in the hopper ele^¬ ment, and no pulling movement was exerted on the hopper element. As a reference, a shorter plate-shaped part was tested at the wall of the hopper element, whereby it was noted that it does not distribute the force of vibration in the hopper element, and the vi^¬ bration causes a pulling movement.

The dispensing apparatus according to the in- vention is suited, through different embodiments, for use in a wide variety of applications for handling a wide variety of materials. Further, the dispensing ap^¬ paratus according to the invention is suited, through different embodiments, for use in a wide variety of industrial environments.

The invention is not limited only to the ex^¬ amples described above; instead many modifications are possible within the scope of the inventive idea de^¬ fined by the claims.
