The purpose of the tank is to collect the water coming from the works yards and all the flushing points of a steel plant plus the rinsing water from the blast furnace, with a concentration of solids of up to 15% of the total volume.
The maximum specific weight is 1.2 kg/l. The tank size is 11 x 9 x 4.5 m (L x W x H), the maximum liquid level is 4.2 m. The continuous flow rate is 20,000 m3/h.
The agitator must be designed for heavy duty (24 hours a day, 7 days a week, 365 days a year), since the basin will have to act as a storage tank to feed the sludge dewatering plant in a continuous cycle.
The PRO-DO-MIX® proposal includes a single agitator, model GEL.A8290.L.425/PCX, with industrial planetary gearbox with AGMA factor > 4. All parts in contact with liquids are covered with 4 mm thick anti-abrasive rubber (EBANITE), to withstand the highly abrasive action of powders and to minimise maintenance requirements throughout the agitator’s life.
The images show the carbon steel impeller, with a diameter of 2,900 mm, completely welded to the shaft, before the rubber covering operations.
For sea freight, a special wooden crate of non-standard dimensions has been created to contain the coated shaft and the impeller during navigation.
Il gradiente di velocità interno della girante Evolution è costante dal centro fino all’esterno della pala.
Questo tipo di girante permette l’installazione di una girante con un grande diametro molto vicino al fondo del serbatoio.
Questo rende Evolution perfetta per applicazioni che richiedano un funzionamento in continuo dell’agitatore, anche durante lo svuotamento del serbatoio.
Diametri disponibili da 1650 a 3500 mm
Disponibile una versione smontabile in 3 parti
