Definitions
- the invention relates to a device for dewatering and washing fiber suspensions with two rollers rotating in opposite directions, a material feed and a material take-off.
- Such systems are known, these having a lateral feed and a downward formation zone in which a fibrous mat is formed. This is followed, if necessary, by a displacement washing zone followed by a press nip. The material is discharged over the two rollers in a repulper screw.
- Such devices have a number of disadvantages, the removal of material in particular being complicated and prone to failure, since the trough of the repulper screw has to be sealed against the rollers. Furthermore, only about half of the volume is used for drainage and washing.
- the aim of the invention is therefore to avoid the disadvantages mentioned and to provide a device for dewatering and washing fiber materials, which ensures a high dewatering performance with laundry and advantageously has a low rewetting of the fiber material mat.
- a favorable embodiment of the invention is characterized in that a guide plate connects to the headbox, the distance to the roll surface continuously decreasing. With this baffle, a continuously increasing pressure on the fiber suspension can be generated and thus a particularly favorable drainage can be carried out.
- a favorable further development of the invention is characterized in that the washing zones are separated on both sides by a separating plate, or alternatively the washing water can be carried out as a common washing pond for both sides.
- a favorable embodiment of the invention is characterized in that the rollers have channels for filtrate removal, the channels being able to have inlets arranged counter to the direction of rotation. If channels are provided for the filtrate discharge, which are arranged in the rollers, large amounts of filtrate and wash water can be removed without problems. A particularly favorable displacement wash can therefore also be realized. If the channels have inlets arranged counter to the direction of rotation, rewetting of the fiber mat is largely prevented. The efficiency of the device can thereby be increased even further.
- a favorable further development of the invention is characterized in that the channels additionally have openings which are connected to the channel preceding in the direction of rotation. This special design enables an even better removal of filtrate and washing water, as a result of which the rewetting can be reduced further.
- a favorable embodiment of the invention is characterized in that the roller surface is designed as a perforated plate with large holes, wherein the holes of the perforated plate can have a diameter in the range from 10 to 25 mm.
- the costs can be reduced since significantly fewer holes are required and the production can also be carried out simply and cheaply.
- the risk of incrustation is much lower and the holes can even be cleaned during operation.
- a favorable development of the invention is characterized in that the rollers are individually covered with sieves. A particularly favorable drainage can be achieved through these screens.
- the combination of these sieves which are supported by the perforated plates, has particular advantages over the previous variants with small holes (1 to 1.5 mm in diameter) drilled in the steel casing of a waizen surface, which, in particular, reduce the risk of incrustation and offer cheaper cleaning options represents.
- the rollers can be designed to be candle-reversible.
- a favorable development of the invention is characterized in that both rollers can be pressed against each other. To control the baling pressure and thereby increase the final dry content of the fiber The rollers can be pressed together with a fabric mat, for example with hydraulic cylinders or other suitable units.
- An advantageous embodiment of the invention is characterized in that the upper parts can be folded down. This enables the rollers to be easily removed without major disassembly work.
- FIG. 1 shows a schematic illustration of the device according to the invention
- FIG. 2 shows a detailed illustration
- FIG. 3 shows a detail X from FIG. 2
- FIG. 4 shows a view in the direction IV in FIG Fig. 2 represents.
- FIG. 1 shows a fibrous scrubber 1 according to the invention with dewatering rollers 2, 3, the respectively assigned stock feed 4, 5 and its stock discharge screw 6.
- the stock suspension is fed evenly over the length through stock feed lines 4, 5 to the rolls 2, 3 at the lowest position.
- the feed can be arranged between the 5 o'clock and 9 o'clock positions. As a result, a much larger part of the circumference of the rollers 2, 3 can be used.
- the suspension is further guided into the areas 8, 8 'formed by the guide plates 7, 8 with the surfaces of the rolls 2, 3, the distance of the guide plates 7, 8 from the surface of the rolls 2, 3 continuously decreasing. This ensures a constant increase in pressure and favorable drainage while simultaneously forming a fiber mat.
- the washing liquid is fed via lines 9, 10 to the washing zones 9 ′′, 10 ′′, which are delimited by sheets 9 ′, 10 ′.
- the distance between the sheets 9 ', 10' to the surface of the rollers 2, 3 can decrease continuously in the direction of rotation DR1, DR2, so that here too an increasingly higher pressure is achieved for the displacement washing.
- scrapers 11, 12 are then provided, through which the Fiber mat and in particular the residues still adhering to the surfaces of the rollers 2, 3 are removed and fall into the discharge screw 6.
- Hinged upper parts 13, 14 are provided for better accessibility during maintenance work, especially when replacing the rollers.
- Spray nozzles 15, 16 are arranged in the lower region of the rollers 2, 3 for further cleaning of the surfaces.
- FIG. 2 shows an illustration analogous to FIG. 1, the same parts being designated with the same reference symbols.
- the hydraulic cylinders 17, 18 for pressing the rollers 2, 3 together can be seen in particular.
- the cylinders 19, 20 for lifting off the upper parts 13, 14 and the positioning cylinders 21, 22 for the removal scrapers 11, 12 can be seen.
- Also shown in the upper area are webs 23, 24 for the operating personnel.
- Fig. 3 now shows a section X from Fig. 2, in which the drainage and washing function is shown in more detail.
- the same reference numerals have been used as in the other figures.
- Fig. 3 specifically shows the channels 25 of the rollers 2, 3 through which the filtrate and the washing water are removed.
- the inlets 26 arranged counter to the direction of rotation DR1, DR2 are clearly visible here, the flow of filtrate or wash water taking place according to the arrows 27.
- the liquid is then discharged axially from these channels 25.
- the variant with additional openings 28 is shown, through which the filtrate can flow into the channels preceding in the direction of rotation DR1, DR2. Since the filtrate has already been at least partially discharged in these channels, the volume of the channels 25 can therefore be used to receive filtrate or wash water from previous channels 25 used and thus the tendency to rewet can be further reduced.
- Fig. 4 now shows the view according to arrow IV in Fig. 2. From this it can be seen that for better distribution of the suspension supply over the length of the rollers 2, 3, a plurality of material supply lines 4, 4 'and correspondingly on the rear side 5, 5' (not shown) can be provided.
- the bearings 29, 30 for the shaft ends 31, 32 of the roller 2 and the gear 34 can also be seen.
- the filtrate is collected in a trough below the rollers.
- the invention is not limited to the variants shown, rather the washing zone can also be designed as a washing pond.
- the washing water is fed in centrally, which means that it is automatically divided into two fiber mats.
- the roller shells can also consist of drilled perforated plates and can be operated without screen covering.
