Rozmělňovací nůžGrinding knife

Oblast technikyTechnical field

Vynález se týká rozmělňovací ho nože pro komorové mělnění materiálů.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comminution knife for chamber grinding of materials.

Dosavadní stav technikyBACKGROUND OF THE INVENTION

V současné době známé rozmělňovací nože pro komorové mělnění materiálů, sestávají z podélné lišty, která je na jednom svém konci opatřena průchozím otvorem pro uložení v rotoru, přičemž náběhová hrana nože má, v řezu vedeném rovinou kolmou na osu průchozího otvoru, konvexní tvar, nebo konkávní tvar, nebo tvar přímky.The currently known grinding knives for chamber grinding of materials consist of a longitudinal bar which is provided at one end with a through hole for receiving in the rotor, the leading edge of the knife having a convex shape in a cross-sectional plane perpendicular to the axis of the through hole; concave or straight line shape.

Rozmělňovací nože s náběhovou hranou ve tvaru přímky jsou nevýhodné v tom, že rozmělňovaný materiál klouže po náběhové hraně nože, čímž dochází jednak ke snížení mlecího účinku, a jednak k ohřevu rozmělňovaného materiálu vlivem tření o náběhovou hranu. Účinek rozmělňování materiálů je velmi nízký a k jeho zvýšení se využívají různé kryogenní postupy, kdy zmrazením materiálu dojde k jeho zkřehnutí.Grinding knives with a leading edge in the form of a straight edge are disadvantageous in that the material to be ground slides along the leading edge of the knife, thereby reducing the grinding effect and heating the grinding material by friction against the leading edge. The grinding effect of the materials is very low and various cryogenic processes are used to increase its brittleness by freezing the material.

Uvedené nevýhody sice nevykazují rozmělňovací nože jejichž náběhová hrana má konvexní nebo konkávní tvar, ale jejich nevýhodou pro rozmělňovací proces neoptimálně vytvořený tvar jejich zakřivení.These disadvantages do not have the crushing knives whose leading edge has a convex or concave shape, but their disadvantage for the crushing process is their non-optimally shaped curvature.

Podstata vynálezuSUMMARY OF THE INVENTION

Výše uvedené nevýhody odstraňuje jednak rozmělňovací nůž pro komorové mělnění materiálů, sestávající z podélné lišty, která je na jednom svém konci opatřena průchozím otvorem pro uložení v rotoru, přičemž náběhová hrana nože má, v řezu vedeném rovinou kolmou na osu průchozího otvoru, konvexní tvar, podle tohoto vynálezu, jehož podstata spočívá v tom, že • · • ·On the one hand, the above-mentioned disadvantages are eliminated by a pulverizing knife for the chamber grinding of materials consisting of a longitudinal bar which is provided at one end with a through hole for receiving in the rotor, the leading edge of the knife has a convex shape in cross section. according to the present invention, which is based on the fact that

Výhodou vytvoření logaritmické spirály, nebo náběhových hran nožů ve tvaru Archimédovy spirály, nebo evolventy kružnice, je zajištění vyššího rozmělňovacího účinku při přímém kontaktu nože s rozmělňovaným materiálem při stejné spotřebě energie.The advantage of creating a logarithmic spiral, or leading edges of knives in the shape of an Archimedes spiral, or an involute of a circle, is to provide a higher comminution effect when the blade is in direct contact with the comminuted material with the same energy consumption.
