Description
Apparatus and Method for Treating Spreadable Material
Description
The invention relates to an apparatus for treating a spreadable material with pressure and heat, having a) at least one hopper for storing the spreadable material, b) at least one spreading device for dispensing the spreadable material from the hopper, c) a conveyor belt onto which the spreadable material can be spread, and d) a device for applying pressure and heat to the spreadable material being conveyed, by the conveyor belt, in the belt’s direction of travel.
The invention also relates to a method of treating spreadable material by means of said apparatus.
The spreadable material spread onto the conveyor belt will be referred to below as a mat of spread material. These mats of spread material can have thicknesses of a few millimetres to a metre. In the invention, the device for applying pressure and heat to the spreadable material (i.e. the mat of spread material) being conveyed by the conveyor belt in the belt’s direction of travel is generally implemented in the form of a twin-belt press. Apparatuses of the kind under consideration are often used for two purposes. For one thing, they are used to make products out of compressed, spread-out, material. In this regard, the invention is focused on the production of chipboards and fibreboards, as is known in the art from EP 1 236 552 B1.
Alternatively, such apparatuses are used to dewater spreadable material.
In this respect, the invention relates to e.g. the dewatering of coal, as is known in the art from DE 100 16 944 A1.
The application of pressure compresses and compacts the mat of spread material, and the application of heat liquefies binding agents or evaporates moisture.
In both possible uses of the apparatus, it is at times desirable to achieve variations across the material’s width, at right angles to the direction of travel. Up to now, it has been, in particular, a matter of adjusting the material’s density. For example, when producing chipboard for furniture manufacture, it may be desired to create regions of higher density and therefore greater strength for hinges to be subsequently attached to, while making the rest of the board as light as possible.
Such cross-sectional adjustments have hitherto been achieved in an onerous manner, by means of the differential dispensing capabilities of the spreading devices. Valves or spreading rollers of a “spreading head” have been regulated, by adjusting their aperture size or rotational speed, in order to distribute the material — usually containing lignocellulose — either evenly or deliberately unevenly over the width of the mat. These methods have not been particularly successful, being highly dependent on the consistency of the spreadable material, namely the size, density, and moisture content of its particles, plus many other factors.
The objective of the invention is therefore to be able, in a simple manner, to give the mat of spread material different physical and/or chemical properties in its cross-section.
As regards the inventive apparatus itself, the objective of the invention is achieved by providing the hopper with a number of compartments, at right angles to the direction of travel, that can be filled with spreadable material differing in its physical or chemical properties.
This makes it possible to spread “different” material on the conveyor belt at right angles to the direction of travel. “Different” may mean, in this case, that the same material is present in all of the compartments, but in a different physical form, e.g. different in particle size. Or else, “different” may mean that chemically different spreadable material is present in the different compartments, or that at least one additive is added to one of the compartments. Spreading the material onto the conveyor belt thus results in mats of spread material with different physical properties at right angles to the belt’s direction of travel, e.g. differences in density or degree of dryness, or may result in mats that have different chemical properties across their width. What is crucial here is that the material differs from compartment to compartment. In this way, the physical and/or chemical properties of the mat of spread material will differ over the width of the mat, thus also influencing the resultant end product.
The invention provides distinct benefits for both of the applications mentioned, by way of example, in the introductory part of the description. When producing boards (or slabs), it is now much easier, for example, to adjust their strength properties, specific weight, or thickness over their width than has previously been possible.
When dewatering spreadable material such as coal, for example (but also to a limited extent when producing chipboard, in which the moisture contained also needs to be evaporated by applying heat), it is possible to prevent the mat of spread material from crumbling away at the edge during the pressing operation, by mixing stabilising additives in and thus enabling the mat to avoid the pressure applied and undergo little or no dewatering at the edge.
Therefore, it is beneficial if the hopper has, at right angles to the conveyor belt’s direction of travel, at least two edge-compartments and at least one middle compartment. In the case of dewatering coal, the edge-compartments would, like the middle compartments, be filled with coal, but with woodchips admixed, for example. The wood chips prevent the coal from breaking away at the edges in the twin-belt press, while having no adverse effect on the coal’s subsequent combustion product.
Preferably, the compartments contain spreadable material with different mean particle sizes. “Particles” here is to be understood as meaning all particles, grains, granules, pieces, and suchlike, of the spreadable material. When chipboards are being produced, the compartments may advantageously contain different chip sizes. In addition, the compartments may contain chips with different concentrations of binding agents, to produce certain regions with different strengths. In this way, significant savings can be made on material and expensive binding agents.
It is beneficial if a number of hoppers, with several compartments each, are arranged one after another in the direction of travel. This provides for still more variations as regards different structural properties of the mat of spread material. Most preferably, the individual compartments will not be arranged in alignment from hopper to hopper, but will be offset relative to one another. This makes it possible to specifically impart different physical or chemical properties to the mat (which is to be compacted), not only over its width but also over its thickness — and irrespective of whether board (or slab) production or dewatering is being undertaken.
Preferably, when a number of hoppers are arranged one after another in series, a number of spreading devices and conveyor belts, associated with the hoppers, will also be provided. In this way, the individual layers of the resultant mat of spread material can be intentionally kept separate and only brought together just before being fed into the device for applying pressure and heat to the spreadable material being conveyed on the conveyor belts.
It is beneficial if the device for applying pressure and heat to the spreadable material being conveyed by the conveyor belt in the belt’s direction of travel is a continuous press for compressing the mats of spread material so as to form an end product. These well-proven presses are to be used in a manner known in the art. The pressures attainable for coal-dewatering should be up to 6 MPa.
The press preferably comprises a lower, heated, pressing and heating plate, an upper, heated, pressing and heating plate, and respective endlessly-circulating steel belts. Using steel for the belts gives the press a long working life with high heatability of up to 240°C.
Preferably, a suction-type extractor device is installed inside the press, to the side of the mat of spread material, to remove the steam arising. This enables the mat of spread material to be dewatered even more effectively.
It is advantageous if the conveyor belts and/or steel belts are water-permeable. This enables the mat of spread material to be dewatered over the entire operating width when being formed into a board (or slab) or merely being dried.
Preferably, a pretreatment station is provided, upstream of the device for applying pressure and heat to the spreadable material being conveyed by the conveyor belt in the belt’s direction of travel. As a beneficial further development, the invention thus proposes that a mat of spread material, and/or another such mat, be pretreated in this pre-treatment device before being brought together. This pre-treatment device may be one that serves for smoothing, edging, steaming, preheating, pre-compacting, and/or levelling. In this way, any slight irregularities occurring when physically or chemically different materials are spread can be evened out.
As regards the method of the invention, the objective of the invention is achieved, using the apparatus described above, through the following steps: - before the spreadable material is treated, at least two compartments are at least partly filled with spreadable materials having different physical or chemical properties, - then, the spreadable materials are spread, by at least one spreading device, onto at least one conveyor belt, to form at least one mat of spread material, and - finally, in a device for applying pressure and heat to the spreadable material being conveyed, the spread material is dewatered and formed into an end product.
It is advantageous if the at least one spreading device spreads different spreadable materials side by side in the conveyor belt’s direction of travel, to produce a mat of spread material. In this way, a mat of spread material is produced that has the desired different chemical or physical properties throughout its cross-section.
Preferably, to assist the treatment process, the mat of spread material is first passed through a pretreatment station, where the mat of spread material can be evened out in various respects. For example, its edge may also be additionally compacted.
The invention will now be described in more detail through examples of its embodiment, making reference to the drawings, in which:
Fig. 1 is a diagrammatic, partly sectioned, representation of an apparatus according to the invention,
Fig. 2 is a detailed representation of the spreading device of the inventive apparatus, and
Fig. 3 explains, diagrammatically, the design of the hopper of the inventive apparatus.
Fig. 1 is a simplified representation of an apparatus for producing fibreboards, e.g. MDF boards. This apparatus has a first spreading machine 2a for producing a first mat of spread material 3a on a first conveyor belt 4a and a second spreading machine 2b for producing a second mat of spread material 3b on a second conveyor belt 4b, and also has a continuous press 5 for squeezing the mats 3a, 3b of spread material together to produce an end product 1 — in the present example, an engineered wood board. Producing the mats 3a, 3b of spread material on the first and second conveyor belts 4a, 4b may mean, to start with, that the mats 3a, 3b are spread directly onto those conveyor belts. However, producing the mats 3a, 3b on the conveyor belts 4a, 4b and applying the material to the conveyor belts 4a, 4b may also mean that the mats 3a, 3b are first spread onto separate conveyor belts located upstream, and then transferred onto the first and second conveyor belts 4a, 4b respectively.
As to the apparatus 1 for treating the spreadable material 21, 22 with pressure and heat, this apparatus is a continually operating press 5 which basically consists of: a lower, heated, pressing and heating plate 6; an upper, heated, pressing and heating plate 7; and respective endlessly-circulating steel belts 8 that bear upon the pressing plates 6, 7, with winding shafts interposed, and form a press nip 10 and a feed-in mouth 11. The steel belts 8 are often porous and water-permeable.
Turning now to Fig. 2, it can be seen that the spreading machines 2a, 2b associated with the two conveyor belts 4a, 4b each have a hopper 12 (not shown in detail) with a spreading device 13. The hoppers 12 are dealt with in greater detail in the description of Fig. 3. The spreading device 13 consists essentially of a dispensing belt 14 and a number of dispensing and/or break-up rollers 15. The spreadable material is conveyed by a hopper belt (i.e. a distributor belt 12a) to the dispensing and/or break-up rollers 15, which essentially break up agglomerations of the material to be spread. Inside the spreading device 13, the spreadable material 21, 22 is distributed onto a spreading head 16 mounted above the respective conveyor belt 4a or 4b and with its end next to the end of the dispensing system. The spreading head 16 is a screen-type spreading head 16 with a screen floor 17 and a plurality of stirring elements 18 — with a given stirring width — that are mounted at a given distance above the screen floor 17. For further details of the screen-type spreading head 16, see WO 03/053642 A1.
By means of the two spreading machines 2a, 2b shown, a mat of spread material 3a, 3b is produced on each respective conveyor belt 4a, 4b. In the drawings, the two spreading machines 2a, 2b each spread the spreadable material directly onto the respective conveyor belts 4a, 4b, which project into the feed-in mouth 11. It is also possible, however, for the spreading machines 2a, 2b to each distribute onto a conveyor belt (not shown) located upstream of the conveyor belts 4a, 4b shown, from which the mats of spread material are then transferred onto the conveyor belts 4a, 4b projecting into the feed-in mouth 11.
The same Fig. 1 may also serve, however, to illustrate an apparatus for treating a spreadable material 21,22 with pressure and heat, in the form of a dewatering apparatus. The design is almost identical. However, the spreading device 13 need not be as complex in design as is required for producing fibreboard. In such an apparatus, coal for instance is spread onto one or more conveyor belts 4a, 4b, and is then compacted and dried in the press 5. It should be pointed out that, when compressing coal — unlike when producing chipboards — pressures of up to 6 MPa are required. The end product 1 in this case is a compressed solid fuel.
It is also indicated, in Figs. 1 and 2, that the two spreading machines 2a, 2b are each followed by a pretreatment station 27, 28. These stations may each have e.g. a scalping unit 29 and a pre-compacting unit, e.g. a prepress 30. In many cases, it is also beneficial to have a suction device for steam extraction, to assist the dewatering process.
Fig. 3 now concentrates on the actual invention. The hopper 12 was only indicated sketchily in Figs. 1 and 2, but is now shown clearly in crosssection, with the section taken at right angles to the direction of travel 19. The hopper 12 runs essentially the entire width of the mat of spread material 3 being formed. In this example of an embodiment of the invention, the hopper 12 is divided into three compartments 20.1, 20.2, 20.3, but this number is not obligatory for the invention, as more compartments than that can certainly be provided. In the example shown in Fig. 3, there are two edge compartments 20.1 and 20.3, which contain a first spreadable material 21. The middle compartment is filled with a second spreadable material 22. These first and second spreadable materials 21 and 22 may indeed consist at least partly of the same material, but they do differ from each other in their physical or chemical properties.
For example, when chipboards are being produced, compartments 20.1 and 20.3 may contain smaller-sized wood chips than compartment 20.2 does. This means that their density when spread is greater at the edge. In another example, all of the compartments 20.1, 20.2, 20.3 may be filled with lignite (or “brown coal”) that is to be dewatered. The edge compartments 20.1 and 20.3, however, contain wood chips in addition, to strengthen the mat passing through the press and prevent it from crumbling away at the side.
The compartments each have a separate feeder 23.1,23.2, 23.3 for supplying them with spreadable material 21,22. These feeders are merely indicated symbolically in Fig. 3. Also shown diagrammatically is the spreading device 13, which has already been described in more detail in the description of Figs. 1 and 2. The spreading device 13 can also be divided into a number of separate spreading devices 13.1, 13.2, 13.3, based on the number of compartments.
The spreadable material 21, 22 is spread onto the conveyor belt 4 by the spreading devices 13.1, 13.2, 13.3, and thus forms a mat of the chemically or physically different spreadable materials 21, 22. Although these products lie side by side — possibly overlapping slightly — in the conveyor belt’s 4 direction of travel 19, they do however form a single mat of spread material 3.
The forms of embodiment described can be varied in many respects without departing from the basics of the invention. In particular, apparatuses for treating other board-like or slab-like end products 1 such as wood fibre boards or carbon plates made of compressed spreadable material 21,22 are also possible.
