Definitions
- the present invention relates to a device for obtaining non-ferrous metals from mixtures of non-ferrous metals and oxides according to the preamble of claim 1.
- a device of this type is known from EP 0 828 858 Bl.
- This document describes a furnace wherein the furnace housing is provided with a receiving mandrel for a drum. Drums containing non-ferrous metal residues are moved into the furnace housing and pushed on to the drive mandrel, for example with a fork-lift truck. Then, a cover or lid is closed against the furnace housing and the process can take place. After sufficient separation has been achieved, with the furnace closed, an opening which communicates with an opening in the side wall of the drum (which must be in the correct rotational position) is opened up in the housing and then the metal is tapped.
- Both the step of positioning the drum on the mandrel and the step of tapping metal require care and attention and cannot be carried out by untrained staff. Moreover, the method of handling imposes limits on the dimensions of the drum.
- US-A-3.468.524 discloses a device wherein a ring-shaped furnace housing is provided which is made from two semi- cylindrical parts.
- a pot or drum is provided which can rotate.
- One side (loading side) of the pot is open whilst the other side of the drum provides the closure. If for some reason the drum has to be removed from the furnace the furnace housing is split.
- the object of the present invention is to avoid these drawbacks and provide a furnace which can be operated in a simple way and wherein the risk of errors, with all the associated consequences, is minimized.
- the drum is placed on the cover in the open position of the cover.
- the cover or lid will generally comprise a plate-like part, which will preferably be approximately horizontal in the fitting/removal position of the drum. In this position, it is relatively easy to place the drum on, for example, a drive mandrel of the drive means in the cover, certainly compared to placing the drum on a mandrel which is located in the preferably obliquely positioned housing of the furnace and is not visible during the positioning operation.
- the drive mechanism can be incorporated in the cover, more particularly on the outer side of the cover.
- the final drive means for the drum which is preferably a mandrel, extends through the wall of the cover. It is correspondingly easy to place the drum on a mandrel of this type.
- the drum can be put in place in the customary way using a fork-lift truck. It is also possible to attach a gantry track or the like. In any event, in the design according to the present invention, the drum is easy to access during the step of positioning it on the cover.
- the furnace is arranged on a frame. More particularly, the furnace housing is transferred tiltably on to a frame, so that it can be tilted between a position of use as described above and a transport position.
- This transport position is more compact, and consequently in a particular embodiment of the invention it is possible for the furnace to be transported inside a standard container. As a result, one single furnace can be used at various locations without the need for further special measures.
- the discharge opening of the drum is arranged so as to extend through the cover.
- the drum is also moved between a position in which the separation of metal and dross takes place and a position in which it is easy to remove the metal from the drum.
- An opening formed in the drum can function as a vent in the position for separating metal and dross and then, when the cover with the drum arranged on it is tilted, can function as a pouring opening.
- This pouring opening can easily be arranged above an opening in the cover in the pouring position. Beneath this, it is in turn possible to position a receptacle or the like for receiving the metal obtained.
- the furnace housing is provided with a fan.
- the remaining pure metal it is preferable (depending on the particular metal) for the remaining oxide to remain in the furnace for further rotary movement, in order for the residue as far as possible to be obtained in the form of a fine powder.
- the residue it is important for cooling of the residue to take place, and to this end it is preferable to use forced cooling. Cooling of this type can be obtained using fans. If fossil fuel is used as medium for heating the furnace, the fans used will generally be suitable for this purpose (in this case of course no fossil fuel is then being fed to the burner).
- the cover of the furnace in this operating mode in which the powder is being comminuted and cooling is taking place, is open a few degrees.
- the invention also relates to an assembly comprising the device described above together with a number of drums. These drums can be used at various locations for collecting the waste in question and can if desired be combined with the furnace in order to obtain the material in question.
- the present invention also relates to a method for separating non-ferrous metals and oxides thereof, comprising placing a mixture of non-ferrous metals and oxides thereof in a drum, placing said drum in a furnace, rotating said drum during the heating of said furnace and tapping of the non-ferrous metal which is released, wherein said drum is secured rotationally to the cover of said furnace and is moved into and out of the furnace with the cover.
- furnace described above can be used for any conceivable material, it is preferably used for non-ferrous metals, in particular lead, zinc, tin or antimony.
- Fig. 1 diagrammatically depicts a perspective view of the furnace according to the present invention in the open position
- Fig. 2 shows the furnace from Fig. 1 in the closed position
- Fig. 3 diagrammatically depicts a cross section through the furnace from Fig. 2;
- Fig. 4 diagrammatically depicts the furnace in the cooling position
- Fig. 5 shows the furnace in the transport position.
- 1 denotes a furnace according to the present invention.
- This furnace is arranged on a frame 2.
- the furnace comprises a furnace housing 3 and a cover 4.
- Furnace housing 3 can pivot about rotation point 14.
- the support 13 of the furnace housing 3 is rigidly connected to rod 15, which can be secured at connection 16.
- Cover 4 can likewise pivot about rotation point 14. The movement thereof is controlled by jack 18, which on the other hand is supported on the frame 2. The movement path of the cover is realized using a control means which is not otherwise shown.
- the cover 4 comprises a cover plate 5 or lid which includes insulating ceramic material.
- a drive mandrel 8 extends through it and can be rotated, via a transmission 9, by a motor 10 likewise arranged in the cover plate 5.
- drum 7 which is provided with an internal sleeve 11 which can mate with mandrel 8 in such a manner that when mandrel 8 rotates drum 7 likewise rotates.
- Material 17 that is to be treated can be arranged in the drum.
- the furnace housing is provided with infrared radiators 12 which provide heating.
- the opening which the cover 4 closes off is denoted by 19.
- Drum 7 is provided with an opening 21.
- This opening 21 can be closed and serves as a pouring opening. As can be seen from Fig. 1, in the pouring position this opening 21 is located above outlet 20, which is in turn located above receptacle 22, which collects the metal to be obtained.
- the outlet 20 also serves as a vent opening.
- the device described above operates as follows. Starting from the position shown in Fig. 1, there is no drum 7 on the mandrel 8. Then, a drum 7 filled with the material mixture that is to be separated is arranged on the mandrel with a fork-lift truck, crane or other equipment. This positioning is relatively easy to achieve, since in the position shown in Fig. 1 the drum is accessible from all sides when it is being placed on mandrel 8. Then, cover 4 with the drum 7 located on mandrel 8 is completely closed against housing 3 with jack 18, producing the position shown in Figs. 2 and 3. In this position, the axis of rotation of drum 7, which is denoted by 24, extends at an angle ⁇ with respect to the horizontal.
- This angle is preferably between 5 and 45°, and is more particularly approximately 10-20°.
- the furnace is heated, thereby heating the contents 17 of the drum 7 being inside the furnace. Heating takes place as a function of the desired metal.
- the purified metal is then removed from the furnace by virtue of the cover being moved back into the position shown in Fig. 1. Then, the opening 21 is opened, after which the metal passes via outlet 20 into receptacle 22. Thereafter, oxide (dross) remains in the furnace. It may be desirable for this oxide to be comminuted.
- the device described here it is possible for the device described here to be designed as a mobile device. Since in such a case the dimensions of the furnace make transport more difficult, it is possible for the furnace housing to be tilted into the position shown in Fig. 5. As a result of the securing at 16 being released, the furnace housing can be tilted, resulting in a more compact structure, which can be designed in such a manner that it can be transported in a standard container or on a lorry without exceeding the relevant height restrictions.
