Abstract

Inventia se refera la un dispozitiv de transport, de taiat, de omogenizat respectiv de amestecat, precum si la un dispozitiv pentru introducerea oscilatiilor respectiv vibratiilor în lichide si paste vîscoase care urmeaza sa fie transportate. Scopul inventiei consta în aceea de a transporta în mod sigur substante vîscoase cu un continut deosebit de ridicat substanta deosebit de ridicat de substanta uscata precum si proportii mari de gaze sau aer. Inventia consta în aceea de a crea un agregat de pompa centrifuga cu utilizare universala printr-un rotor executat în mod deosebit de adecvat din punctul de vedere al tehnicii curgerii si prin diferite dispozitive variabile din pompa centrifuga. Conform inventiei, la un rotor semideschis cu iesire crescînda a sectiunii de iesire axiala maxima la un diametru care paletele prezinta o îngustare axiala maxima la un diametru care este aproximativ 2/3 din diametrul exterior al rotorului ca rotorul este prevazut cu sau fara dispozitv de taiat si ca înaintea rotorului ca rotorul este prevazut cu sau fara dispozitivul de taiat si ca înaintea rotorului este montat un melc de alimentare în sine cunoscut cu sau fara dispozitiv de taiat iar înaintea melcului de alimentare este montat un vibrator.The invention relates to a device for transporting, cutting, homogenizing or mixing, as well as to a device for introducing oscillations or vibrations in the viscous liquids and pastes to be transported. The purpose of the invention is to safely transport viscous substances with a particularly high content of high dry substance substance as well as large proportions of gas or air. The invention consists in the creation of a centrifugal pump unit with universal use by a rotor which is particularly well suited from the point of view of the flow technique and by various variable devices in the centrifugal pump. According to the invention, in a semi-open rotor with an increasing output of the maximum axial output section at a diameter that the blades exhibit a maximum axial narrowing at a diameter that is about 2/3 of the outer diameter of the rotor, the rotor is provided with or without cutting device and that before the rotor the rotor is provided with or without the cutting device and that a feed auger itself is known prior to the rotor known with or without a cutter and a vibrator is mounted in front of the feed auger.
