Abstract
The invention relates to a machine for micro-filtering solid particles suspended in a liquid stream comprising: a couple of coaxial filtering discs (5, 6, 20, 21, 91, 92, 93, 94) rotating around its own axis (71) arranged horizontal and normal to direction of the flow to be treated and at least a partially cylindrical wall (7) defining together with the rims of said couple of discs a hydraulic sealing coupling so as to enclose the liquid treating space comprising at least the rotation axis. Each disc of said couples of discs is provided with one or more washing ramps (14, 15) arranged outside said treating chambers and provided with nozzles throwing water against said discs at the portions emerging (51, 61) from the treating chamber. The washing water is collected by at least a liquid conveyance channel (8) feeding the liquid back to the purification plant arranged upstream said machines.
Claims (7)
1)A machine for micro-filtering solid particles suspended in a liquid stream comprising:
- a feeding chamber (2) communicating through a duct with - one or more treating chambers (4,95,96), each of said chambers being defined by a couple of coaxial filtering discs (5,6,20,21,91,92,93,94) rotating around their own axis (71) arranged horizontally and normal to the direction of the flow to be treated, and at least a partially cylindrical wall (7) defining together with the rims of said couple of discs a hydraulic sealing coupling so as to enclose the liquid treating space to comprise at least the rotation axis;
- conveyance chambers (10,11,97,98,99) for the treated liquid provided with bottom outlets (101,110) communicating with - at least a collection chamber (12, 100) for the liquid coming from said conveyance chambers, provided with liquid discharge pipes;
- means (70, 80) for transmitting the rotation motion to said filtering discs, characterized in that each disc of said couples of discs is provided with one or more washing ramps (14, 15) arranged outside said treating chambers and provided with nozzles throwing water against said discs at the portions (51, 61) of said discs emerging from said treating chambers, said washing water being collected by at least a conveyance channel (8) for the liquid and the particles collected with said washing operation, arranged between said couples of discs above the treating chamber and ending with a duct (82) feeding the liquid back to the purification plant arranged upstream said machine.
- a feeding chamber (2) communicating through a duct with - one or more treating chambers (4,95,96), each of said chambers being defined by a couple of coaxial filtering discs (5,6,20,21,91,92,93,94) rotating around their own axis (71) arranged horizontally and normal to the direction of the flow to be treated, and at least a partially cylindrical wall (7) defining together with the rims of said couple of discs a hydraulic sealing coupling so as to enclose the liquid treating space to comprise at least the rotation axis;
- conveyance chambers (10,11,97,98,99) for the treated liquid provided with bottom outlets (101,110) communicating with - at least a collection chamber (12, 100) for the liquid coming from said conveyance chambers, provided with liquid discharge pipes;
- means (70, 80) for transmitting the rotation motion to said filtering discs, characterized in that each disc of said couples of discs is provided with one or more washing ramps (14, 15) arranged outside said treating chambers and provided with nozzles throwing water against said discs at the portions (51, 61) of said discs emerging from said treating chambers, said washing water being collected by at least a conveyance channel (8) for the liquid and the particles collected with said washing operation, arranged between said couples of discs above the treating chamber and ending with a duct (82) feeding the liquid back to the purification plant arranged upstream said machine.
2)The machine according to claim 1) characterized in that said filtering discs (5, 6) have a generally flat surface.
3)The machine according to claim 1) characterized in that said filtering discs (20, 21) have a generally frustum conical surface.
4)The machine according to claim 1) characterized in that each of said discs is provided on its circumferencial rim with a gasket (52, 62, 202, 212) so as to warrant the hydraulic seal with the partially cylindrical wall defining said treating chamber.
5)The machine according to claim 1) characterized in that the partially cylindrical wall is provided with gaskets (52,62, 202, 212) so as to warrant the hydraulic seal between said wall (7) and said filtering discs sliding on said wall.
6)The machine according to claim 1) characterized in that the means for transmitting the rotation motion to the filtering discs comprise a ratio motor (70) connected to the horizontal shaft (71) supporting said couples of filtering discs.
7)The machine according to any of claim 1) characterized in that the means for transmitting the rotation motion to the filtering discs comprise a ratio motor having a slow shaft integral with a pinion (81) engaged with a wheel gear (82) arranged on the circumference of a filtering disc (83).
