Abstract

Device for treating swimming pool or pond water, which distributes the solution (corrosive or otherwise) for treating the water by means of a sampler (6) of calibrated and adjustable capacity filled via a main storage tank (4) in which the solution is stored. The sampler is drained by means of air at low pressure generated by a microcompressor (12) switched on automatically according to regular periods controlled by a clock (14) or manually by overriding the clock or by another system (example: pH meter).

Description

The present invention relates to a device for treating water from
pool or basin that distributes a treating product (Microbicide or
anti-algae, basic or acid) via a reservoir
calibrated and adjustable capacity sampler drain by air
compressed under low pressure.

On the distributing devices for treating products offered
currently on the market, two techniques are essentially used:
one is to use the depression created at the entrance to the body of the
filtration pump to suck up the treatment products, the other distributes
the product by means of a dosing pump.

* The first technique presents the operating disadvantages
following:
- juicy placement on already existing installations suette â
synchronization problems between the clock that controls
the solenoid valve for opening or closing the product supply
processing and the clock that controls the opening or closing cycle of the
pool filtration pump
- bad aspiration of the treating products and therefore bad
water treatment caused by the loss of suction power of the filtration pump when the sand or diatom filter is saturated
after a certain number of filtration cycles of the pond water: it is
then necessary to wash the filter so that the depression created by the
pump is powerful enough to suck up the products again
contractors.

- also poor aspiration of treatment products when the
filtration pump is arranged at a lower level than the basin.

* The use of pumps (Specialized or backpacks) or vacuum
created z3 the inlet of the body of the filtration pump to suck the
treatment products, can also lead to difficulties in
following operation:
- need to use crusty materials which must be able
operate in aggressive environments such as:
"solenoid valves or metering pumps to supply water to a basin
in products treating Hypochlorite of liquid soda (i.e. bleach, anti-algae, acid or basic solution etc ...) from a tank
containing the treating product.

- If for any reason, the electro-mechanical mechanisms
used such as "solenoid valve or pump" remain in operation,
the entire product reservoir is emptied into the water in the basin or the
swimming pool å. treat, which can make the water toxic and dangerous for
humans or animals.

- as the solenoid valves or pumps are in contact with the product
treating itself in contact with pond water, it is mandatory
to use a 25 V voltage supply for safety
higher bur.

In its simplest version of solution distribution
icrobicide or anti-algae or basic acid the proposed device
has a reservoir which empties into an intermediate reservoir or
sampler drained by compressed air under low pressure
generated by a micro-compressor launched automatically according to
Erlodicity regulated by a clock several months in advance or
cruelly by forcing the clock. This device has the advantage
to provide the following solutions to the various drawbacks
4i. dence previously on the previous techniques used:
- Sum the product is driven from the sampler by air under low
pressure, it is not necessary to use the vacuum created at the inlet
of the pump body to suck up the treating products during the
operation of the filtration pump, hence the following advantages:
simplification for adapting the device to installations
because there is no longer a problem of synchronization between
clocks of the existing installation and the clock which controls the sending of
products process. Indeed, this synchronization difficulty requires
@cuvent, in the case of current devices sold on the market, the
costly change of the entire control system of the
pool filtration, In the case of the new device proposed,
@@ micro-compressor control clock is unique and independent
of any prior device which allows adaptability to the slightest
cost to existing systems. Synchronization is performed only
approximately by placing the operating range of the micro-compressor (approximately one minute) within a larger operating range of the filtration pump (for example 2 hours).
the device allows, thanks to its independence vis à vis the pump
filtration, do not modify the water treatment, even if the filtration unit does not operate under normal conditions.

- ie device no longer requires costly use
@ solenoid valves or metering pumps operating in corrosive environments.
as no electromechanical device is in contact
directly with water treatment products, this device can
@@@ be without particular difficulties even a very microbicidal product
"'r: market whose effectiveness is no longer to be demonstrated like sodium hypochlorite, that is to say bleach of considerable aggressiveness even vis 8 viS of stainless steel or materials plastics like neoprene.

- the device authorizes by a pipe of reduced diameter (6 millimeters) the direct supply of the suction mouth (without non-return valves) or indirect by the pipe at the inlet of the filtration system (with non-return valves). This last more expensive option is to be considered only in the extreme case of impossibility of access to the mouth: in this these, only there is requires the presence of a mechanical device.

(Check valves).

- The device has the particularity of presenting maximum security of the supply of the basin with treating product and of the electrical supply of the device.

even if for any reason, the clock remains in the on position due to a mechanical anomaly or a forgetting of the device in the forcing position, the micro-compressor can only drain the volume of product contained in the sampler.
as the emptying of the sampler is carried out by means of low pressure sinus air channeled in flexible plastic tubes there is no direct contact between the water treatment liquid and the micro-compressor. This independence of the circuits does not make the use of a 25V tensioner compulsory, which allows the safe use of a micro-compressor powered by 220V and consequently lowers the cost price of the device.

- As this device makes a solution latch of a calibrated quantity, it has a "shock" effect which gives better efficacy to the solution and therefore allows a reduction in doses in the case of liquid chlorine in particular. On the other hand, these ruptures do not allow the water in the basin to get used to a given concentration, which again ensures better efficiency of the treating products: this is one of the non-negligible advantages of the device compared to the expensive pumps. dispensers which regularly send a larger quantity of products continuously for a lower result. These releases will be carried out at night to avoid any use of the swimming pool during the treatment and to increase the effectiveness of chlorine treatment in particular.

- The volume and the frequency of releases depends on the characteristics of the solution used and the amount of water in the basin
As the treatment products mixed with the pool or pond water have the particularity of gradually losing their property as a function of time, the use of a probe (pH meter, chlorination) is not always necessary: thus, the use of a clock to control the releases of products is sufficient to treat swimming pools since the drift of the pH or of the concentration of chlorination and ani-elgue $ is generally linear over time. Thus, for a 100 m3 swimming pool used on a "spring summer" period of 6 months, we see that the treatments
The following in volume and frequency are sufficient to maintain the water in perfect conditions:
1.25 liter of liquid chlorine at daily intervals
0.25 liter of anti-algae weekly
0.15 liter of acid solution if water tends to become basic
or conversely 0.15 liter of basic solution if the water tends
to become acidic (weekly frequency).

Over the six-month "autumn winter" period, the lachers will spend
@@ weekly frequency for chlorine and monthly for others
products. These volumes are indicative and must be adjusted accordingly
climatic characteristics of the region and water quality.

- Finally, all connections to the various tanks and
samplers or pipes are made by means of
plastic cable glands, which give the system a large
flexibility of installation and adjustment as well as remarkable longevity
born in a corrosive environment.

Thus, the present invention radically simplifies the systems
supply of basins or pools with products treat and
thus contributes to. make the device described more reliable and less costly
This den is detailed below.

We will first describe the detailed form of the invention by way of
indicative in no way limiting by referring to FIG 1, then some
peculiarities of the device with reference to FIGS 2 and 3
At the level of the detailed description we distinguish two cases:
- in the first case, if the tap (11) is open and the (the) closed, the device operates as a water treatment system:
The swimming pool or basin (1) has a conventional filtration circuit
consisting of suction pipes (2) connected to a system
sand or diatom filtration (fO) and a pump, as well as
return pipes (3) bringing the water in a closed circuit into the
p @@ cine (1). The invention proper comprises a reservoir (4)
fed by (8B, containing the treatment product (5) which is poured into
ur.- 'sampler tank (e) through the pipeline
your grace ô the pipe (17), the calibrated diameter hole (29) in
'aut of the filter brings back the sampler tank to the pressure
atmospheric and thus allows its filling. Every time
the sampler is full, the clock (14) powered by the electric circuit (15), can then start, thanks to the electric circuit (13), according to an automatic program defined in advance or manually by forcing, the micro-compressor (12), for emptying the sampler of a fixed ô advanced volume (21). Thus, several sequences can be launched sequentially in automatic or manual mode, to adjust the quantity of product treating to the volume of the basin (Maintenance or
forcing etc.). The compressed air created by the micro-compressor passes through a
filter (16), which prevents contact for example of chlorine vapors with the micro-compressor. After passing the filter (16), the compressed air
pressurizes the sampler (6) through the pipe (17). As the pipes (27) and (26) are then closed by a non-return valve (7), the treatment product can only pass through the pipe (which communicates directly with the basin (1) through the suction mouth (30) or with pipes (2) or (3). As soon as the micro-compressor is stopped by the clock (14) in manual or automatic mode, the sampler (6) fills again and the cycle emptying the sampler (6) can resume with a new dose of treating product.

 - in the second case, if the tap (11) is closed and the (18) open, the device operates as an inflation system for tires or other pool games.

The present invention also includes the following non-limiting features for the invention patent
- The sampler (e) or FIG 2 is of calibrated and adjustable capacity (22) according to the height (of the tube (9) which plunges into the solution: the product (20) located between the end of the tube and the bottom of the The sampler is therefore not used. You just have to adjust the height of the tube which plunges into the solution using the stuffing box (19) to fix the volume of product which will treat the basin or the swimming pool at each start-up. of the micro-compressor.

- The non-return valve (7) or FIG 3 and Fig 5 consists of a
very economically directly with the supply lines. The flexible plastic pipe, obstructed when the sampler is pressurized, is cut straight (25), while the pipe, which must remain open when the tank is emptied into
the sampler is cut into a point (2e). The two pipes are joined by a flexible tube (24) in which slides a ball (23) which
ensures the closing or opening of the pipes according to the pressure
internal of the sampler.

 - the non-return valve (7) linked to the tee (28) avoids in the case of a tank higher than the level of the swimming pool, the siphoning effect caused during a power cut before the drain cycle complete or sampler tank.

 - All connections to the various tanks and samplers or pipes are made using FIS 4 plastic cable glands.

- The device can carry out the microbicide, anti-algae and nasal or acid treatment independently or integrated:
either by making an identical device for each treating product. In this case, each solution tank is drained so: independently by its own clock.
or or by partially doubling the device by the use of the same micro-compressor to drain the treatment products each contained in their own tank. The compressed air is then brought to the water of each sampler tank thanks to a directly controlled pneumatic circuit. by solenoid valves themselves each controlled by a clock assigned to a product to process. This solution is more
economical than the previous one since the solenoid valves used in pneumatic circuits are less expensive than the micro-compressors.

 - This device can be integrated into a more elaborate system using detection probes, for example of PH threshold or of chlorine oncentration. But in this case, as the test carried out by the waves and the associated processing must be carried out during the operation of the pump, there is then no escape from a synchronization of the device with the filtration cycle. On the other hand, as it is necessary to exclude the simultaneous 18chers (Ex Chlorine + acid), the different tests must be staggered in time by a central clock.
