Detailed description of the invention
First the conveyor 1 configured to carry and transport a material bed through a furnace and some embodiments and variants of the conveyor will be described in greater detail.
The conveyor 1 comprises a material carrying surface 2 configured to carry the material bed.
The conveyor 1 comprises at least two endless conveyor chains 3 and a plurality of lamella members 15 secured to said at least two endless conveyor chains 3.
Each endless conveyor chain 3 is engaged with at least two wheels 4.
At least one of said at least two wheels 4 is a chain drive sprocket wheel. A driving means such as an electric, pneumatic, or hydraulic motor may be provided to drive to the chain drive sprocket wheel.
Said plurality of lamella members 15 forming the material carrying surface 2 of the conveyor 1.
Compared to the elements forming a conveyor belt, the lamella members 15 can have a much simpler construction, partly due to the fact that the elements of a conveyor belt must have connection means for connecting the elements of the conveyor belt together to form the conveyor belt. This also makes service and maintenance of the conveyor 1 easier than service and maintenance of a conveyor belt. To keep the conveyor belt laterally in position is also easier than to keep a conveyor belt laterally in position, because it is more easy to keep a chain in position on a wheels 4 than to keep a conveyor belt in position on rollers. Another advantage is that the two endless conveyor chains 4 can be provided so that they are outside the furnace or at an outer edge of the furnace resulting in that a small thermal load will be subjected on the said at least two endless conveyor chains 4.
Said at least two endless conveyor chains 3 are preferably, but not necessarily, made of metal.
Said at least two endless conveyor chains 3 are preferably, but not necessarily, identical and arranged to run in parallel at a distance from each other.
Each lamella member 15 of said the plurality of lamella members 15 extend preferably, but not necessarily, between at least two endless conveyor chains 3 of said least two endless conveyor chains 3. Each lamella member 15 can have two parallel lateral sides 5, a front side 6 and a trailing side 7 that is parallel with the front side 6.
A chain guide 8 may be provided and configured to steer the endless conveyor chain 3 laterally.
The lamella members 15 have preferably, but not necessarily, side walls 9. Such side walls
9 raises the capacity of the conveyor 1 as more material can be loaded onto the material carrying surface 2 of the conveyor 1, because the side walls 9 prevents the material from falling off the conveyor from the sides of the conveyor. The complete width of the conveyor can be utilized for carrying material. The side walls 9 can be lateral side walls, project perpendicularly or at least partly in an angle and/or curved with respect to a lamella member 15.
The lamella members 15 are preferably, but not necessarily, releasable secured to said at least two endless conveyor chains 3. This allows faster changing of individual lamella members 15, for example when a lamella member 15 travels on the underside of the conveyor.
The lamella members 15 are preferably, but not necessarily, secured to said at least two endless conveyor chains 3 by means of a pivoting arrangement 10 allowing each lamella member 15 to pivot with respect to said at least two endless conveyor chains 3. A lamella member 15 can for example be configured to hang on the underside from the chain, when the lamella member 15 travels on an underside of the conveyor 1, and/or a lamella member 15 can be configured to rest on the upper side on the chain, when the lamella member 15 travels on an upper side of the conveyor 1, as is illustrated in figure 4. An advantage of this is that it allows better inspection of the condition of the lamella members 15.
Alternatively, the lamella members 15 can be constructed and designed so that only a part of each lamella member 15 is allowed to pivot with respect to said at least two endless conveyor chains 3.
Adjacent lamella members 15 may overlap as shown for example in figure 2. An advantage of this is that material of the material bed does not fall between two adjacent lamella members 15.
A transversal wall 11 can be formed in the conveyor 1 at the points of the conveyor 1 where two adjacent lamella members 15 overlap.
Adjacent lamella members 15 are preferably, but not necessarily, unattached to each other. An advantage of this is that it is easier to replace single lamella members 15, which are not attached to other lamella members 15.
The lamella members 15 are preferably, but not necessarily, made of metal or of other heat- resistant material. An advantage of this is that lamella members 15 of metal can withstand heat and fatigue. The lamella members can for example be made of cast iron, non-alloy steel, alloy steel such as stainless steel, acid-proof steel, or fire-proof steel. The lamella members 15 can also be made of or comprise ceramic material and heat-resistant polymer. The lamella members 15 can also be made of a combination of at last two of metal, ceramic material and heat-resistant polymer. Which material that is selected is dependent of the process conditions. The lamella members 15 are preferably, but not necessarily, perforated 12. An advantage of this is that it allows gas to flow through the lamella members 15 and the material.
The lamella members 15 are preferably, but not necessarily, identical in shape and dimensions. An advantage of this is that easier to replace single lamella members 15 if they are interchangeable. This leads also to the fact that a smaller amount of different spare parts needed.
The conveyor 1 can have sliding members 13 for supporting the lamella members 15.
The lamella members 15 can, as illustrated in figures 8 and 9, be provided with a lining 16 so that the lining 16 of the lamella members forms the material carrying surface 2 of the conveyor. The lining 16 can comprise at least one of autogenous material, insulating material, fatigue- resistant material, wear-resistant material, heat-resistant material, or fire-resistant material. The lining 16 can alternatively be a coating comprising at least one of autogenous material, insulating material, or fire-resistant material. The lining 16 or the coating can cover at least partly the lamella member 15 and at least partly the possible side walls 9, provided that the lamella member 15 is provided with such side walls 9. The material bed that is conveyed will also form a protective layer protecting the lamella member 15. The material bed that is conveyed can also form a thermal insulation for the lamella member 15.
The invention relates also to a sintering, hardening, or drying equipment comprising a furnace, which is divided into number of sequential process zones, wherein different and/or temperature conditions prevail, and a conveyor 1 according to any embodiment described and configured to convey a material bed through the process zones of the furnace.
Next the sintering, hardening, or drying equipment and some embodiments and variants of the equipment will be described in greater detail.
The sintering, hardening, or drying equipment comprises a furnace, which is divided into number of sequential process zones 14, wherein different and/or temperature conditions prevail.
The sintering, hardening, or drying equipment comprises a conveyor 1 configured to convey a material bed through the process zones of the furnace.
The conveyor 1 comprises a material carrying surface 2 configured to carry the material bed.
The conveyor 1 comprises at least two endless conveyor chains 3 and a plurality of lamella members 15 secured to said at least two endless conveyor chains 3.
Each endless conveyor chain 3 is engaged with at least two wheels 4.
At least one of said at least two wheels 4 is a chain drive sprocket wheel. A driving means such as an electric, pneumatic, or hydraulic motor may be provided to drive to the chain drive sprocket wheel.
Said plurality of lamella members 15 forming the material carrying surface 2 of the conveyor 1.
Compared to the elements forming a conveyor belt, the lamella members 15 can have a much simpler construction, partly due to the fact that the elements of a conveyor belt must have connection means for connecting the elements of the conveyor belt together to form the conveyor belt. This also makes service and maintenance of the conveyor 1 easier than service and maintenance of a conveyor belt. To keep the conveyor laterally in position is also easier than to keep a conveyor belt laterally in position, because it is more easy to keep a chain in position on a wheels 4 than to keep a conveyor belt in position on rollers. Another advantage is that the two endless conveyor chains 4 can be provided so that they are outside the furnace or at an outer edge of the furnace resulting in that a small thermal load will be subjected on the said at least two endless conveyor chains 4.
Said at least two endless conveyor chains 3 are preferably, but not necessarily, made of metal.
Said at least two endless conveyor chains 3 are preferably, but not necessarily, identical and arranged to run in parallel at a distance from each other.
Each lamella member 15 of said the plurality of lamella members 15 extend preferably, but not necessarily, between at least two endless conveyor chains 3 of said least two endless conveyor chains 3.
Each lamella can have two parallel lateral sides 5, a front side 6 and a trailing side 7 that is parallel with the front side 6.
A chain guide 8 may be provided and configured to steer the endless conveyor chain 3 laterally.
The lamella members 15 have preferably, but not necessarily, side walls 9. Such side walls 9 raises the capacity of the conveyor 1 as more material can be loaded onto the material carrying surface 2 of the conveyor 1, because the side walls 9 prevents the material from falling off the conveyor 1 from the sides of the conveyor 1. The complete width of the conveyor 1 can be utilized for carrying material. The side walls 9 can be lateral side walls, project perpendicularly or at least partly in an angle and/or curved with respect to a lamella member 15.

A lamella member 15 can for example be configured to hang on the underside from the chain, when the lamella member 15 travels on an underside of the conveyor 1, and/or a lamella member 15 can be configured to rest on the upper side on the chain, when the lamella member 15 travels on an upper side of the conveyor 1. An advantage of this is that it allows better inspection of the condition of the lamella members 15.
Alternatively, the lamella members 15 can be constructed and designed so that only a part of each lamella member 15 is allowed to pivot with respect to said at least two endless conveyor chains 3.
Adjacent lamella members 15 may overlap as shown for example in figure 2. An advantage of this is that material of the material bed does not fall between two adjacent lamella members 15.
A transversal wall 11 can be formed in the conveyor 1 at the points of the conveyor 1 where two adjacent lamella members 15 overlap.
Adjacent lamella members 15 are preferably, but not necessarily, unattached to each other. An advantage of this is that it is easier to replace single lamella members 15, which are not attached to other lamella members 15.
The lamella members 15 are preferably, but not necessarily, made of metal, or of other heat-resistant material. An advantage of this is that lamella members 15 of metal can withstand heat and fatigue. The lamella members 15 can also be made of or comprise ceramic material and heat-resistant polymer.
The lamella members 15 are preferably, but not necessarily, perforated 12. An advantage of this is that it allows gas to flow through the lamella members 15 and the material.
The lamella members 15 are preferably, but not necessarily, identical in shape and dimensions. An advantage of this is that easier to replace single lamella members 15 if they are interchangeable. This leads also to the fact that a smaller amount of different spare parts needed.
The conveyor 1 can have sliding members 13 for supporting the lamella members 15. The lamella members 15 can, as illustrated in figures 8 and 9, be provided with a lining 16 so that the lining 16 of the lamella members forms the material carrying surface 2 of the conveyor. The lining 16 can comprise at least one of autogenous material, insulating material, or fire-resistant material. The lining 16 can alternatively be a coating comprising at least one of autogenous material, insulating material, fatigue-resistant material, wear-resistant material, heat-resistant material, or fire-resistant material. The lining 16 or the coating can cover at least partly the lamella member 15 and at least partly the possible side walls 9, provided that the lamella member 15 is provided with such side walls 9. The material bed that is conveyed will also form a protective layer protecting the lamella member 15. The material bed that is conveyed can also form a thermal insulation for the lamella member 15.
It is apparent to a person skilled in the art that as technology advanced, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are therefore not restricted to the above examples, but they may vary within the scope of the claims.
