Abstract
A cyclonic valve for cleaning pumps for transferring powders of any type in high density, including an inlet duct for introducing a flow of cleaning fluid, a flow dividing element adapted for dividing the flow in inlet into a plurality of flows, and a flow orienter having means for deviating and orienting in space the plurality of flows so as to give each of the flows a tangential motion component with respect to the direction of the flows, and then conveying the flows into one or more ducts towards the device to be cleaned, so as to generate a single cleaning flow in outlet having helical motion.
Claims11
1) Cyclonic valve for cleaning pumps for transferring high density powders of any type, comprising:
- an inlet duct for introducing a flow of cleaning fluid,
- a flow dividing element adapted for dividing the flow in inlet into a plurality of flows, and
- a flow orienter comprising means for deviating and orienting in space said plurality of flows so as to give each of said flows a tangential motion component with respect to the direction of said flows, and then convey said flows into one or more ducts towards the device to be cleaned, so as to generate a single cleaning flow in outlet having helical motion.
10) Method for cleaning pumps for high density powders comprising the steps of:
- conveying a cleaning flow of air or gas towards an inlet duct;
- dividing said cleaning flow into a plurality of flows;
- giving said plurality of flows a tangential motion component and joining them back together, conveying them through one or more ducts towards the pump to be cleaned, thus giving the resulting flow a helical motion.
11) Method for cleaning pumps for high density powders according to claim 11, wherein said resulting flow having helical motion is conveyed in the pumping chamber of said pump for high density powders in which a pumping tube is housed.
