Abstract
The present invention concerns a method and equipment for compacting a material. In particular, the present invention relates to the vibration of "green mass" in a moulding process for the creation of mould bodies for the production of electrodes for the melting industry, in particular the alumini um electrolysis industry. The equipment comprises two mould parts (m~l, m~b) th at are mutually integrated with a spring force, which may consist of one or mor e springs (k~3). At least one of the mould parts is equipped with means design ed to generate vibration. In one embodiment, the equipment consists of a lower table with mould walls and an upper plumb. In a preferred embodiment, vibration is applied via the plumb. During vibration, the plumb will move downwards towards the table as a consequence of the intermediate mass being compacted. The table may be supported by a base in which at least one spring (k1) and possibly a damper element (d1) are arranged between the table and t he base. The springs of the equipment may be designed in such a way that the plumb and the table are allowed to oscillate at one or more given frequencie s that produce maximum gain against the mass to be compacted. The damper eleme nt (d1) will have a stabilising and insulating function. The compaction may tak e place at a specific vacuum for the removal of gas.
Claims (18)
1. A method for compacting a material, in particular vibration of "green mass"
in a moulding process for the creation of mould bodies for the production of electrodes for the melting industry, in particular the aluminium electrolysis industry, comprising equipment with two mould parts, at least one of which has vibration applied to it during the compaction process, the mould parts are mutually physically integrated during vibration by means of a static compressive force that may consist of at least one spring, characterised in that the mould parts are directly connected by the spring(-s) (k3).
in a moulding process for the creation of mould bodies for the production of electrodes for the melting industry, in particular the aluminium electrolysis industry, comprising equipment with two mould parts, at least one of which has vibration applied to it during the compaction process, the mould parts are mutually physically integrated during vibration by means of a static compressive force that may consist of at least one spring, characterised in that the mould parts are directly connected by the spring(-s) (k3).
2. A method in accordance with claim 1, characterised in that the static compressive force can be regulated during the vibration process independently of the position of the mould parts.
3. A method in accordance with claim 1, characterised in that the spring (k s) has minimal damping and exhibits a progressive spring force so that the static force between the mould parts is kept constant regardless of the position of one mould part in relation to the other during compaction.
4. A method in accordance with claim 1, characterised in that the vibration is carried out mainly in the vertical direction.
5. A method in accordance with claim 4 in which the mould parts consist of a lower table equipped with mould walls and an upper plumb designed to move downwards towards the table as a consequence of the intermediate mass being compacted and in which the table is supported by a base, characterised in that the table is supported against the base by means of at least one spring (k1) and possibly a damper element (d1).
6. A method in accordance with claim 5, characterised in that the characteristics of the spring (k1) and the damper element (d1) are also chosen so that virtually all mechanical energy that is made available by the vibration applied is insulated from the base and is supplied to the material to be compacted.
7. A method in accordance with claims 1-3, characterised in that the vibration is carried out mainly in the horizontal direction.
8. A method in accordance with claims 1-7, characterised in that at least one of the mould parts has vibration applied to it at a frequency such that the mould parts contribute to maximum gain of dynamic force against the mass (m a) to be compacted, for example by the mould parts oscillating in' virtual phase opposition.
9. A method in accordance with claims 1-8, characterised in that the mass (m a) to be compacted is subjected to a vacuum.
10. Equipment for compacting a material, in particular vibration of "green mass" in a moulding process for the creation of mould bodies for the production of electrodes for the melting industry, in particular the aluminium electrolysis industry, comprising equipment with two mould parts, at least one of which has vibration applied to it, the mould parts are mutually physically integrated by means of a static compressive force, which may consist of at least one spring, characterised in that the mould parts are directly connected by the spring (-s) (k3).
11. Equipment in accordance with claim 10, characterised in that the spring (k3) has an adjustable static compressive force.
12. Equipment in accordance with claim 10, characterised in that the spring (k3) has minimal damping and also has a progressive spring force so that the compressive force is constant regardless of longitudinal changes to the spring.
13. Equipment in accordance with claims 10-12, characterised in that the spring (k3) consists of one or more elastic, gas-filled bellows in which the gas pressure can be adjusted.
14. Equipment in accordance with claims 10-13 in which the mould parts are vibrated in the vertical direction and also consist of a lower table equipped with mould walls and an upper plumb designed to move downwards towards the table as a consequence of the intermediate mass being compacted and in which the table is supported by a base, characterised in that the spring (k3) is connected between the table and the plumb via a structure that can be height-adjustable and that also extends up from the table and has a part that can be located above the plumb, which structure is permanently connected to the table.
15. Equipment in accordance with claim 14, characterised in that the table is supported against the base by means of at least one spring (k1) and possibly a damper element (d1).
16. Equipment in accordance with claim 14, characterised in that the plumb has vibration applied to it.
17. Equipment in accordance with claims 10-16, characterised in that the mass (m a) is compacted within a vacuum chamber (Vr) in which a vacuum is provided.
18. Equipment in accordance with claim 17, characterised in that the vacuum chamber (Vr) is delimited by means of mould walls (Fv1, Fv2), the table and a vacuum lid (Vk).
