NOVELTY - The mixing pump for catalyst containing liquid mixture substance from partly-dried sewage sludge and biomass, comprises a pump housing (4), a motor-driven drive shaft (12), which guides into the pump housing, an inlet (18) and an outlet for the mixture substance, which is delivered by a crack-mechanism, and a blade-propeller (20) with number of blades, which are connected to the drive shaft. The drive shaft is aligned vertically. The outlet of the pump housing is arranged at the base (8). The blades are manufactured from high-grade steel.    USE - Useful for mixing catalyst containing liquid mixture substance from partly dried sewage sludge and biomass.    ADVANTAGE - The cracking process ensures improved splitting up of the mixing substance into volatile and solid components, when a mixing pump is used, thus increased energy efficiency can be obtained.    DETAILED DESCRIPTION - The mixing pump for catalyst containing liquid mixture substance from partly-dried sewage sludge and biomass, comprises a pump housing (4), a motor-driven drive shaft (12), which guides into the pump housing, an inlet (18) and an outlet for the mixture substance, which is delivered by a crack-mechanism, and a blade-propeller (20) with number of blades, which are connected to the drive shaft. The drive shaft is aligned vertically. The outlet of the pump housing is arranged at the base (8). The blades are manufactured from high-grade steel. An optimal speed of the drive shaft is adjusted on the mixing substance, so that in the operation of the mixture substance a shearing force is produced and a thermal energy entry take place, and a considerable improvement of the cracking-behavior of the supplied mixing substance occurs. In the pump housing below the blades a material-folding plate is diagonally arranged, which leads the mixed substance from the blades towards the direction of the outlet. The optimal speed is variable from 500-6000 U/min. A separator is arranged below the pump housing for the separation of heavy foreign substances, which are conveyed by the propeller space. The separator is provided with a cleaning opening, which is arranged laterally. The drive shaft is pivoted in a bearing, which is cooled by a coolant. The mixture substance possesses a temperature within the range of 250-380degreesC, which lies in the range of the cracking-temperature. A variation mechanism is intended for the change of the gap between blades and pump-stator and for the twist of the blades and works based on a mechanical-hydraulic principle.
