1. Field of the Invention
The present invention relates to a separating device, and more particularly to a separating device for separating anolyte from catholyte in electrolytic cells or electrolyzers or for preventing the anolyte and the catholyte from being mixed or blended with each other.
2. Description of the Prior Art
Typical electrolytic cells or electrolyzers comprise anodes and cathodes disposed within a cell body or container that is provided for receiving electrolyte therein, for generating anolyte and catholyte by energizing or actuating or operating the anodes and the cathodes, and for utilizing the anolyte and the catholyte to electroplate work pieces, for example.
In some circumstances, the anolyte and the catholyte are required to be separated from each other, for such as manufacturing or separating chlorine and caustic from brine. Accordingly, one or more separators or separating devices are required to be disposed or engaged into the electrolytic cells or electrolyzers for separating the anolyte and the catholyte from each other in the typical electrolytic cells.
For example, U.S. Pat. No. 4,292,146 to Chang et al. discloses one of the typical electrolytic cells including a porous polyfluoroalkylene sheet disposed therein and acted as a separator for the electrolysis of brine and for separating the anolyte and the catholyte from each other.
However, the typical porous polyfluoroalkylene sheet is good enough for separating the anolyte and the catholyte from each other in a static or motionless electrolyte in the electrolytic cells or electrolyzers, but the typical electrolytic cells or electrolyzers have no devices for separating and collecting the anolyte and the catholyte from the flowing electrolyte.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional separating devices for separating the anolyte and the catholyte from each other in the electrolytic cells or electrolyzers.
The primary objective of the present invention is to provide a separating device for separating anolyte from catholyte in electrolytic cells or electrolyzers or for preventing the anolyte and the catholyte from being mixed or blended with each other.
In accordance with one aspect of the invention, there is provided an electrolyzer comprising a receptacle including a chamber formed in the receptacle, and including an inlet port for receiving an electrolytic solution, at least one cathode plate and at least one anode plate disposed in the chamber of the receptacle and separated from each other for forming a flowing passage between the cathode plate and the anode plate, the cathode plate being provided for attracting anolyte of the electrolytic solution toward the cathode plate, and the anode plate being provided for attracting catholyte of the electrolytic solution toward the anode plate, the receptacle including a first compartment and a second compartment communicating with the chamber of the receptacle respectively, the first and the second compartments being separated from each other and not communicating with each other, and a guiding device for guiding the catholyte and the anolyte to flow into the first and the second compartments of the receptacle respectively.
The receptacle includes a conduit formed in the receptacle and communicating with the first compartment of the receptacle, and an outlet port communicating with the conduit for flowing out the catholyte.
The receptacle includes a partition disposed between the first compartment and the conduit of the receptacle, and a passage formed in the partition for communicating the first compartment with the conduit of the receptacle.
The receptacle includes two housing members secured together, the housing members each includes the outlet port formed therein, and a coupler coupled to the outlet ports of the housing members respectively.
The receptacle includes a window for blocking the first compartment with the conduit of the receptacle and for allowing a flowing of the catholyte from the first compartment toward the conduit of the receptacle to be seen by people. The receptacle includes an exit communicating with the second compartment for flowing out the anolyte.
The receptacle includes at least one peg extended therefrom and engaged through the cathode plate and the anode plate for stably supporting and anchoring the cathode plate and the anode plate in the chamber of the receptacle.
One or more spacers are disposed between the cathode plate and the anode plate for separating the cathode plate and the anode plate from each other. The cathode plate includes at least one groove formed therein, and the spacer includes a portion engaged into the groove of the cathode plate.
The guiding device includes a deflector extended from the cathode plate and extended into the first compartment of the receptacle for guiding the catholyte to flow into the first compartment of the receptacle.
The guiding device includes a guiding projection extended and directed into a middle portion of the flowing passage which is formed between the cathode plate and the anode plate for separating the catholyte and the anolyte from each other, and for guiding the catholyte to flow into the first compartment of the receptacle and for guiding the anolyte to flow into the second compartment of the receptacle.
The receptacle includes a partition disposed between the first and the second compartments for separating the first and the second compartments from each other, and the guiding projection is extended from the partition.

The anolyte 70 may be generated and attracted toward the cathode plate 30 and may thus be forced or caused to flow closer to the cathode plate 30, and may then be guided to flow into the second compartment 18 of the receptacle 10 by the cathode plate 30 itself and/or by the separating or guiding projections 29 of the partitions 28, and may then be guided to flow out of the receptacle 10 via the exits 24 and/or the connector 25 of the housing members 11, 12 respectively, for then allowing the anolyte 70 to be collected for further use.
Simultaneously, the catholyte 80 may be generated and attracted toward the anode plates 40 and may thus be forced or caused to flow closer to the anode plates 40, and may then be guided to flow into the first compartment 17 of the receptacle 10 by the bent segments or deflectors 45 of the anode plates 40 and/or the separating or guiding projections 29 of the partitions 28, and may then be guided to flow into the conduits 19 of the receptacle 10 and then to flow out of the receptacle 10 via the coupler 23 or the outlet ports 22 of the housing members 11, 12 respectively, for allowing the catholyte 80 to be collected for further use.
The cathode plate 30 and the anode plates 40 may thus be used for generating the anolyte 70 and the catholyte 80 respectively, and for guiding the catholyte 80 to flow into the first compartment 17 of the receptacle 10, and then to flow into the conduits 19 of the receptacle 10, and for guiding the anolyte 70 to flow into the second compartment 18 of the receptacle 10. The bent segments or deflectors 45 of the anode plates 40 and/or the separating or guiding projections 29 of the partitions 28 may thus be acted as a separating means or device for separating the anolyte 70 and the catholyte 80 away from each other, and for effectively guiding the catholyte 80 and the anolyte 70 to flow into the first compartment 17 and the second compartment 18 of the receptacle 10 respectively.
