Abstract

A találmány tárgya aprítószivattyú szilárd anyagokat tartalmazószennyvíz továbbítására mint forgó térfogat-kiszorításos szivattyú,egy villamos motorral, egy szivattyúházzal, egy helyhez kötöttszivattyúállórésszel és egy excentrikusan ágyazottszivattyúforgórésszel, valamint egy aprítószerkezettel, amely legalábbegy állókésből és legalább egy forgókésből áll, ahol azaprítószerkezet a szivattyúforgórésznek a villamos motorhajtótengelyétől távolabb eső végén keresztül van meghajtva, és ahol akések egymás felett fekvő, vágónyílásokkal ellátott tárcsákként vannakkialakítva, amely vágónyílások körív alakú vagy sarló alakú vágóéleketképeznek, és legalább két vágónyílás a forgókés legalább egyszöghelyzetében legalább részben átfedi egymást. A találmány lényegeaz, hogy a vágónyílásoknak a forgókés (6) forgásirányában előresietőperemszakaszai az állókés (5) és a forgókés között egy-egy szabadteret képező módon hátrametszéssel vannak ellátva. ÓThe subject of the invention is a shredder pump for conveying waste water containing solids as a rotating positive displacement pump, with an electric motor, a pump housing, a stationary pump stand and an eccentrically embedded pump rotor, and a shredder consisting of at least one fixed blade and at least one rotary blade, where the shredder is connected to the pump rotor from the electric motor drive shaft is driven through the farther end, and where the blades are designed as superimposed discs with cutting openings, which cutting openings form circular arc-shaped or sickle-shaped cutting edges, and at least two cutting openings at least partially overlap each other in at least an angular position of the rotary knife. The essence of the invention is that the forward edge sections of the cutting openings in the direction of rotation of the rotary knife (6) are provided with a back cut in such a way as to form a free space between the stationary knife (5) and the rotary knife.
