Replaceable chlorinator electrode assembly
View Patent ↗The invention relates to an apparatus for electrolytic purification, comprising: (a) a pressure vessel having at least one access opening, at least one fluid flow inlet, and at least one fluid flow outlet, wherein the fluid flow inlet and fluid flow outlet are in fluid communication with a chamber inside the pressure vessel; (b) an removable electrode assembly, at least a portion of which is disposed within the chamber inside the pressure vessel, comprising: a plurality of substantially parallel spaced planar electrodes, an electrical coupling between the electrode plates and a voltage source, and a radially extending circumferential sealing plate substantially normal to the planes of the electrodes, disposed near the electrical coupling, adapted to prevent fluid flow from the chamber to the electrical coupling; (c) a removable locking ring, comprising: a proximal portion adapted to removably attach to the access opening of the pressure vessel and retain the radially extending circumferential sealing plate of the electrode assembly against the pressure vessel access opening.
1. An apparatus for electrolytic purification, comprising:
(a) a pressure vessel having at least one access opening, at least one fluid flow inlet, and at least one fluid flow outlet, wherein the fluid flow inlet and fluid flow outlet are in fluid communication with a chamber inside the pressure vessel;
(b) an removable electrode assembly, at least a portion of which is disposed within the chamber inside the pressure vessel, comprising:
a plurality of substantially parallel spaced planar electrodes,
an electrical coupling between the electrode plates and a voltage source, and
a radially extending circumferential sealing plate substantially normal to the planes of the electrodes, disposed near the electrical coupling, adapted to prevent fluid flow from the chamber to the electrical coupling;
(c) a removable locking ring, comprising:
a proximal portion adapted to removably attach to the access opening of the pressure vessel and retain the radially extending circumferential sealing plate of the electrode assembly against the pressure vessel access opening, thereby providing a seal thereto.
2. The apparatus of claim 1 , wherein the pressure vessel comprises a transparent material.
3. The apparatus of claim 1 , wherein the pressure vessel is substantially cylindrical.
4. The apparatus of claim 1 , further comprising an electrode retention ring disposed between the electrode assembly and the access opening, and adapted to orient the electrode assembly within the chamber and to provide a sealing surface for the radially extending circumferential sealing plate of the electrode assembly.
5. The apparatus of claim 1 , wherein the fluid flow inlet is proximal to the access opening and the fluid flow outlet is distal to the access opening.
6. The apparatus of claim 5 , wherein the pressure vessel further comprises a chamber extension located distally of the fluid flow outlet from the access opening.
7. The apparatus of claim 6 , wherein the chamber extension is transparent.
8. The apparatus of claim 1 , wherein the pressure vessel is threaded near the access opening, and wherein the proximal portion of the locking ring is correspondingly threaded, so as to removably attach to the pressure vessel at the access opening.
9. The apparatus of claim 1 , wherein the locking ring further comprises:
a distal portion adapted to extend away from the pressure vessel.
10. The apparatus of claim 9 , wherein the distal portion of the locking ring comprises an opening adapted to receive a cable connected to the electrode assembly.
11. The apparatus of claim 10 , further comprising:
(d) a removable end cap adapted to cover the distal portion of the locking ring. comprising an opening adapted to receive a cable connected to the electrode assembly and to cooperate with the opening in the distal portion of the locking ring to retain the cable and provide a seal thereto.
12. The apparatus of claim 9 , further comprising:
(d) a removable end cap adapted to cover the distal portion of the locking ring.
13. The apparatus of claim 12 , wherein the locking ring and cap are integrated into a single piece.
14. The apparatus of claim 12 , wherein the locking ring and cap are separate pieces that mechanically lock together.
15. The apparatus of claim 14 , wherein the locking ring further comprises at least one radially extending lug or at least one radially extending indent, or both.
16. The apparatus of claim 12 , wherein the cap further comprises at least one radially extending indent or at least one radially extending lug, or both, adapted to respectively receive the radially extending lug or radially extending indent of the locking ring.
