Separation device

Claim 1

A device for separating from a liquid components suspended therein, comprising an assembly of substantially parallel corrugated plates arranged in a basin at an angle with the horizontal plane, between which plates separation passages are defined, which plates are provided with mutually parallel corrugations having generatrices which include an angle of less than 90° with the line of maximum inclination of the plates, two opposite transverse walls of the basin, joining the oblique lateral edges of the plates, forming a connection with a liquid supply and discharge chamber respectively, the shape and dimensions thereof substantially corresponding to the cross-section of the plate assembly parallel to these walls, which chambers are connected to a liquid supply and discharge duct respectively, in such a manner that the liquid flow between these chambers is directed substantially transversely to the corrugations of these plates, the lowest or highest terminal edges respectively of these plates joining collecting ducts for heavy or light components respectively, which are collected in the lowest or highest parts respectively of the plate corrugations and slide along these parts towards the extremity in question, at which extremity of the corrugated plates guiding baffles are provided which are directed towards a collecting chamber for the component in question, which baffles are adapted to prevent a liquid flow past the plate assembly, said corrugated plates extending up to the lateral walls in question of the basin, and contacting the lateral walls of the basin compartment in which the plates are arranged, at their lower edges with their corrugation tops and at their higher edges with their corrugation valleys, there being a distance between the corrugation valleys and tops respectively and the lateral wall in question, and, thus, forming a discharge passage for the separated component flowing off at that extremity, and in that the guiding baffles are mounted against the lateral wall in question, and are aligned with a series of superposed corrugation valleys or tops respectively.

Claim 2

A device for separating from a liquid components suspended therein, comprising an assembly of substantially parallel corrugated plates arranged in a basin at an angle with the horizontal plane, between which plates separation passages are defined, which plates are provided with mutually parallel corrugations having generatrices which include an angle of less than 90° with the line of maximum inclination of the plates, two opposite transverse walls of the basin, joining the oblique lateral edges of the plates, forming a connection with a liquid supply and discharge chamber respectively, the shape and dimensions thereof substantially corresponding to the cross-section of the plate assembly parallel to these walls, which chambers are connected to a liquid supply and discharge duct respectively, in such a manner that the liquid flow between these chambers is directed substantially transversely to the corrugations of these plates, the lowest or highest terminal edges respectively of these plates joining collecting ducts for heavy or light components respectively, which are collected in the lowest or highest parts respectively of the plate corrugations and slide along these parts towards the extremity in question, at which extremity of the corrugated plates guiding baffles are provided which are directed towards a collecting chamber for the component in question, which baffles are adapted to prevent a liquid flow past the plate assembly, said corrugated plates extending up to the lateral walls in question of the basin, and contacting the lateral walls of the basin compartment in which the plates are arranged, at their lower edges with their corrugation tops and at their higher edges with their corrugation valleys, there being a distance between the corrugation valleys and tops respectively and the lateral wall in question, and, thus, forming a discharge passage for the separated component flowing off at that extremity, and in that the guiding baffles are mounted against the lateral wall in question, and are aligned with a series of superposed corrugation valleys or tops respectively.

Claim 9

The device according to any one of claims 1, 2, and 4, further in which the basin is subdivided by means of at least one longitudinal partition into a corresponding number of partial spaces, in each of which partial spaces a plate assembly is arranged.
