FR2709430A1 - Apparatus for electrophysical purification of liquids such as water in swimming pools - Google Patents

Abstract

An electrode-carrier device or ionisation pot made up of two removable portions, employed in the electrophysical treatment of liquids. The electrical connections are produced by a printed circuit (105) inside a plate moulded in the electrically insulating substance formed by the lid (101) or upper part. The copper-silver electrodes (104) are screwed onto metal terminals (102) which are also moulded and connected in parallel to the terminals (103) of a current supply plug, itself also moulded on the external face of the said lid (101). The lower part (100) made of transparent substance is connected into the pipework between the pump and the filter. The assembly of the two portions is produced by manual clamping of two articulated lugs, the leakproofing is ensured by a ring seal (109). No tool is needed for the maintenance operations.

Description

 The present invention relates to a liquid purification device such as swimming pool water.

 The filtration of a swimming pool consists of: a pump which conveys the water, and a filter which retains the impurities.

It is a closed circuit, the water thus filtered returns to the basin where it must be permanently treated to preserve it, sanitize it and rid it of impurities as well as bacteria or micro-organisms which could not be retained in the filtered.

 Generally, chemicals are used which are not without inconvenience; odors, taste, irritation of the eyes, mucous membranes, discoloration etc ... not to mention the cost which remains still high.

 There are methods which can replace these chemicals and thus facilitate maintenance and free users from these unpleasant and repetitive constraints, in particular the method using copper-silver electrodes.

 The process using copper-silver electrodes is called electrophysical treatment of liquids. said electrodes, immersed in said liquid, brought to different electrical potentials release copper-silver metal ions.

The combined action of these ions at a certain concentration has the effect of eliminating various bacteria, fungi and algae. This process has been known for a very long time.

 The electrophysical treatment system must be positioned to be effective, between the pump and the filter, on the piping, before the water enters the filter in order to cause flocculation of the impurities suspended in the water and the destruction of microorganisms, algae etc ...

 It is therefore at this precise location that the ionization vessel containing the electrodes must be located.

 The electrical insulation of the vase is very important. Indeed, the vase is located in a humid environment, maintenance is essential: maintenance of the electrodes (cleaning) replacement of these. Although the current is low voltage, this still requires some essential precautions.

Currently, the ionization vessels are in one piece, each electrode enters the vessel through an orifice, an electrode holder cap keeps the electrode screwed in and ensures electrical contact. Each electrode holder plug is connected to the control box by an insulated plug and an electrical wire. If the vase has for example four electrodes, there will also be four wires that will be connected on top of the vase. All these connections risk presenting a danger to the user during maintenance operations, without forgetting the various manipulations requiring operating tools such as the special key to unscrew the electrodes.

This key enters the electrode holder cap, into a housing provided for this purpose to allow unscrewing.

According to the present invention, the ionization vessel consists of two parts. FIG 1
The upper part (101) consists of a plate of electrically insulating material forming a removable cover, it has on its internal face projecting metal ends (102), molded in the material and electrically connected in parallel to terminals (103). an electrical outlet socket also molded, integral with the external face of the cover (101) and accessible from the outside. Each tip (102) receiving an electrode (104) removably attached to said tip (102) for example by screwing. FIG 2
The particularity of the invention is that the electrical connection between the end pieces (102) and the above-mentioned terminals (103) is carried out by means of a printed circuit (105) embedded in the insulating material of the cover (101).

 There will be no more wires coming out of the vase on each electrode-holder plug, no more plugs to be connected to the said plugs since they are deleted.

All connections are now invisible, resulting in increased security. Only an insulated electrical cable connects the control box to the ionization vessel and is connected on the periphery of the cover (101) to the terminals (103) of an electrical outlet. A single operation is enough to open the vase and therefore access all the electrodes (104) since they are fixed under the cover (101) itself.

 The lower part (100) of the transparent material vessel in which the electrodes (104) are immersed has an inlet and an outlet through which the liquid will circulate. FIG 2 the said lower part (100) is fixed to the piping by gluing.

The assembly of the two parts is done by hand tightening of
Two articulated ears. FIG 1 An annual thoric seal (109) seals between the upper flange (107) and the lower flange (106)
No tools are necessary to dismantle the cover (101) of the vessel.
