Description

Die Erfindung betrifft eine Schneidmühle zur Zerkleinerung von faserigem und nichtfaserigem Material, insbesondere Zellstoffprodukten.The The invention relates to a cutting mill for the comminution of fibrous and non-fibrous material, in particular Pulp products.

Eine derartige sogenannte Messermühle, hier zum Zerkleinern von Kunststoffmaterial, ist aus der DE 102 22 814 bekannt. Diese Messermühle besteht aus einer Rotorwalze und einem konzentrisch dazu angeordneten Lochsieb. Im gesamten Innenraum des Lochsiebes befindet sich der Mahlraum. Auf dem Rotor sind in 120° versetzten Positionen 3 Rotormesser angeordnet. Das Gehäuse nimmt 2 diametral gegenüberliegende Statormesserblöcke auf. Jeder dieser Messerblöcke verfügt über 2 Statormesser.Such a so-called knife mill, here for crushing plastic material, is from the DE 102 22 814 known. This knife mill consists of a rotor roller and a perforated screen arranged concentrically therewith. Throughout the interior of the perforated sieve is the grinding chamber. On the rotor are offset in 120 ° positions 3 rotor blades. The housing accommodates 2 diametrically opposed stator blades. Each of these knife blocks has 2 stator knives.

Zwischen der Rotorwalze und dem Lochsieb befindet sich der Schneidraum. Das zerkleinerte Material gelangt über das Lochsieb in einen Siebkorb und wird von dort durch Unterdruck ausgetragen.Between the rotor roll and the perforated screen is the cutting room. The crushed material passes over the perforated screen in a strainer basket and is from there by negative pressure discharged.

Aufgabe der Erfindung ist es, die Leistung der Schneidmühle zu erhöhen ohne dabei die Konsistenz des zu behandelnden Materials zu verändern.task The invention is to increase the performance of the granulator without sacrificing consistency of the material to be treated.

Ein Beispiel der Erfindung wird anhand der nachfolgenden beispielhaften Darstellungen angeführt:One Example of the invention will become apparent from the following example Representations listed:

Es zeigtIt shows

1 einen vertikalen Schnitt einer Schneidmühle 1 a vertical section of a cutting mill

2 einen vertikalen Schnitt einer Schneidwalze 2 a vertical section of a cutting roller

3 Schnitte eines Gehäuseteiles 3 Sections of a housing part

Die Schneidmühle besteht aus einem Gehäuse 10 mit 2 schwenkbaren Gehäuseteilen 12. Im Inneren des Gehäuses befindet sich eine mit einem Antrieb verbundene Messerwalze. Die Messerwalze weist an ihrem Umfang mindestens 14 Messerblöcke mit mindestens je einem Messer 18 auf. Das Produkt wird mit diesen Messern 18 und den Messern 20, die sich in den Messerblöcken 22 der Gehäuseteile 12 befinden, zerkleinert. Die Messerblöcke 22 nehmen, entsprechend dem Ausführungsbeispiel, jeweils 2 Messer 20 in sich auf.The granulator consists of a housing 10 with 2 swiveling housing parts 12 , Inside the housing is a knife roller connected to a drive. The knife roller has on its circumference at least 14 knife blocks with at least one knife each 18 on. The product is made with these knives 18 and the knives 20 that are in the knife blocks 22 the housing parts 12 are located, crushed. The knife blocks 22 take, according to the embodiment, each 2 knives 20 in itself.

Dadurch, daß die stehenden Messer in den Messerblöcken 22 in den schwenkbaren Gehäuseteilen 12 angeordnet sind, besteht zu diesen Messerblöcken, sofern die Gehäuseteile 12 seitlich nach außen geschwenkt werden, ein verbesserter Zugriff.The fact that the standing knife in the knife blocks 22 in the swiveling housing parts 12 are arranged to these knife blocks, provided the housing parts 12 be pivoted laterally outwards, an improved access.

Da das Material, das in der Schneidmühle bearbeitet wird, teilweise sehr temperaturempfindlich ist, sind die Messerblöcke 22 in den Gehäuseteilen 12 mit einer Kühleinrichtung versehen. Diese Kühleinrichtung besteht in 1 aus einer Wasserkühlung deren Wasser durch die Leitung 24 in den Messerblöcken 22 geführt wird. Je nachdem wie groß der Kühlbedarf ist, können in den Messerblöcken 22 mehrere Kühlleitungen vorgesehen sein. Diese Kühlleitungen können sowohl dicht an der Oberfläche der Messerblöcke 22 angeordnet sein, die in Richtung des Schneidraums 24 gerichtet ist, oder entlang der Oberfläche der Messerblöcke/Spannschienen, die die Messer 20 begrenzt. Bei Bedarf kann die Kühlung auch über die Messerwalze 14 erfolgen, indem im Bereich der Oberfläche der Messerwalze ebenfalls Kühlleitungen verlaufen. Dies kann vergleichsweise wie im Messerbereich des Gehäuses oder an der freien Walzen- oder Rotoroberfläche vorgesehen sein. Als Kühlmedium kann sowohl Wasser oder andere Fluide wie auch Gase oder Luft zum Einsatz kommen. Sollte sich die Kühlung des Produkts im Bereich der Messer zu schwierig gestalten kann auch eine Vorkühlung zur Anwendung kommen, wobei die Kühleinrichtung der Schneidvorrichtung vorgeordnet wird. Die Vorkühlung kann sich je nach dem wie flexibel das Produkt bei Raumtemperatur ist positiv auf den Zerkleinerungsvorgang auswirken, wenn die Kühlung zu einer Stabilisierung des Produkts führt.Since the material being processed in the granulator is in part very sensitive to temperature, the knife blocks are 22 in the housing parts 12 provided with a cooling device. This cooling device consists in 1 from a water cooling their water through the pipe 24 in the knife blocks 22 to be led. Depending on how big the cooling requirement is, can in the knife blocks 22 be provided a plurality of cooling lines. These cooling lines can be both close to the surface of the knife blocks 22 be arranged in the direction of the cutting room 24 is directed, or along the surface of the knife blocks / slide rails, which are the knives 20 limited. If necessary, the cooling can also be done via the knife roller 14 done by also run cooling lines in the area of the surface of the knife roller. This can be provided comparatively as in the knife area of the housing or on the free roll or rotor surface. As a cooling medium, both water or other fluids as well as gases or air can be used. If cooling of the product in the area of the knives is too difficult, pre-cooling may also be used, the cooling device being arranged upstream of the cutting device. Pre-cooling may have a positive effect on the comminution process depending on how flexible the product is at room temperature, if the cooling leads to stabilization of the product.

Zur Erhöhung der Schnittzahl ist entsprechend 2 eine Messerwalze oder ein Messerrotor mit verkürzter Länge mit weniger Messerblöcken vorgesehen, jedoch mit verdoppelter Anzahl von Messern 18. Die Messer 18 sind mit der Messerwalze oder dem Rotor 14 verspannt. Dazu sind je zwei Messern 18 durch keilförmige Schienen 28 über Spannkeile 30 und Schrauben 32 mit der Messerwalze 14 verbunden. Den Schneidwinkel, den die Messer gegenüber der Senkrechten zur Drehachse einnehmen, kann durch die Konizität der Spannschienen 38 oder Spannkeile bestimmt werden. Die unterschiedliche Winkelstellung der beiden unmittelbar nacheinander angeordneten Messer ist abhängig vom Produkt, der Schnittleistung und er Feinheit des gewünschten Endprodukts.To increase the number of cuts is appropriate 2 a knife roll or a knife rotor of shortened length with fewer knife blocks provided, but with doubled number of knives 18 , The knife 18 are with the knife roller or the rotor 14 braced. There are two knives for each 18 through wedge-shaped rails 28 over clamping wedges 30 and screws 32 with the knife roller 14 connected. The cutting angle, which the knives assume with respect to the perpendicular to the axis of rotation, can by the taper of the clamping rails 38 or clamping wedges are determined. The different angular position of the two immediately successively arranged knife depends on the product, the cutting performance and fineness of the desired end product.

Aus 3, einer vergrößerten Darstellung der in den Gehäuseteilen 12 angeordneten Messerblöcke 22, geht die Zuleitung des Kühlmittels hervor. Beispielsweise sind hier die Spannkeile mit Schrauben 34 verbunden, die Bohrungen 36 aufweisen. Diese Bohrungen 36 stehen mit den Kühlmittelleitungen 25 in Verbindung.Out 3 , An enlarged view of the housing parts 12 arranged knife blocks 22 , the supply line of the coolant comes out. For example, here are the clamping wedges with screws 34 connected, the holes 36 exhibit. These holes 36 stand with the coolant lines 25 in connection.

Zusätzlich geht aus 3 hervor, daß die Spannschienen 38 beidseitig von je 2 Schneidmessern begrenzt sind, so daß jeder stehende Messerblock im Gehäuseteil 12 vier Messer 20 aufnimmt. Zur Erhöhung der Kühlung kann die Oberfläche der Spannschiene im Bereich des Schneidraumes 24 kann die Konstruktion in diesem Bereich auch so geändert werden, daß die Spannschiene 38 mit ihrer größeren Stirnfläche in Richtung des Schneidraums weist.In addition, goes out 3 apparent that the tension rails 38 are bounded on both sides by 2 cutting blades, so that each standing knife block in the housing part 12 four knives 20 receives. To increase the cooling, the surface of the clamping rail in the region of the cutting space 24 The design in this area can also be changed so that the clamping rail 38 has with its larger face in the direction of the cutting room.
