Definitions
- the invention relates to a device for drainage and defibering of lignocellulosic material with a snail.
- the invention is now intended to be a controlled defibration and best Bring drainage results.
- a favorable further development of the invention is characterized in that that the defibration body is conical. Through the tapered Execution can build a better pressure and thus a better one Achieve drainage.
- An advantageous embodiment of the invention is characterized in that that the defibering body has ribs, the ribs one Can have angles to the screw axis.
- conical fiberizing body is surrounded by a conical housing is, wherein the conical housing have internal ribs can, which advantageously have an angle with respect to the screw axis.
- a favorable embodiment of the invention is characterized in that that the defibration body is displaceable in the axial direction, wherein alternatively, the conical housing can be axially displaceable.
- the defibration body or the housing can be a Gap setting can be realized during the operation of the machine.
- a favorable embodiment of the invention is characterized in that that another snail connects to the defibration body. As a result, the material can be further compressed and dewatered even better will.
- An advantageous development of the invention is characterized in that that the worm shaft of the further worm has holes that with a hole in the center of this shaft stand, with the hole in the center of this shaft through the fiberizing body is guided to the shaft of the first screw and with openings can be connected in this wave. This allows the last one Use some of the steam generated to preheat the material.
- An alternative embodiment of the invention is characterized in that over the other snail, the defibrillator and the end a pressure housing is attached to the first screw, the pressure housing with a line with a device for preheating the Material can be connected. So can preheat the material before entering the entire device.
- Another alternative embodiment is characterized in that the defibration body and / or the conical housing grooves for Has steam return. So the steam can be directly and without large Losses can be used for preheating in the screw section.
- FIG. 1 shows a device 1 according to the invention with a shaft 2 and an attached helical screw 3, the shaft 2 over the drive shaft 4 is driven.
- the material to be drained like e.g. Wood chips are fed to the screw 3 through the entry opening 5.
- the defibrillating part is connected to this drainage part 6 8 on.
- one connected to the worm shaft 2 ' rotates Cone 9, which is provided with conveyor-shredding ribs 10 ', in one conical jacket 11, on its side facing the cone also has crushing ribs 10 ''.
- another drainage part 12 connect in which a worm shaft 13 with a helical screw 14 presses the loosened and partially shredded material further, the water running through the openings of the screen jacket 15 can.
- the device can e.g. with a fabric silo be connected, with the resulting grafting of the material prevents any steam in this container from escaping becomes.
- the entire screw unit (shaft 2, 2 ', cone 9, shaft 13) can be designed to be displaceable in the direction of arrow 17. This allows the gap between the cone 9 and the conical jacket 11 and thereby adjust or regulate the defibration effect.
- Fig. 2 shows a section along line II-II in Fig. 1. It can be seen here clearly the crushing ribs 10 'attached to the cone 9 and the comminution ribs 10 '' attached to the conical jacket 11.
- Fig. 2a and 2b show the development of possible arrangements of the comminution ribs 10 'and 10' '. The arrangement in Fig. 2a produces one greater shear effect and thus better grinding, while the Arrangement in Fig. 2b better loosening and promotion of Material results.
- the suitable design can be selected.
- Fig. 3 shows a variant of the invention in which the pressure resulting steam through holes 18 in a in the center of the shaft 13 the further screw located bore 17 is guided through the Cone 9 to [in] in the shaft 2 'of the drainage part 6 of the first Auger extends from where the steam through corresponding holes 19 in the less pressurized material is discharged and thus preheating it.
- Fig. 4 shows an alternative to the arrangement of Fig. 3, here the resultant Steam in a region above the area of the further screw 13, 14 arranged the defibration body 9 and the end of the first screw Pressure housing 20 collected and via a line 21 to Preheating the material used in front of the entire device becomes.
- the squeeze water is removed from the pressure housing via a line 22 20 dissipated.
- the steam distribution can also be used here by means of grooves in the cone part, which leads to possible heat losses can be prevented.
- FIG. 5 An alternative to FIG. 4 is shown in FIG. 5, here the steam returned by grooves 23 which are provided in the conical housing 11 becomes.
- the invention is not limited to the examples shown, but rather rather rather includes z. B. in addition to rounded and angular cross sections Fiber ribs. It would also be a constant diameter shaft possible, which rotates in a tapered strainer basket.
