Abstract

Solid chlorine metering device for drinking water in general comprising, essentially, a metering device (1) constituted by a main entrainment water passage structure (2) with an inlet (3) and an outlet (4), said structure (2) including a disinfectant-holder cup (5) for the chlorine tablet (6), forming a dissolution chamber (7) which, in contact with a quantity of water from the intake valve (8), generates a concentrated disinfectant solution that, after passing through solid-residue filters (9 and 10) continues on to the dispersion chamber (11) and then, through the difference in pressure generated by the Venturi (12), to the vicinity of the mixing chamber (13), already with the correct dosage for drinking water, via the flow-control valve (14).

Description

Solid Chlorine Dispenser for Consumption Water in General

Short presentation

It deals with the present patent application of an unprecedented doser, which properly dimensioned meets different flows and human consumption needs of chlorine-treated water, which acts hydromechanically and automatically without the need for registration and electricity, but only by the action of water flow and pressure differential as it passes through the valves and venturi within its main structure.

Application field

The screened doser has as its preferred field of use low-flow residential networks, but not limited to this, for example, it can be applied in condominiums, swimming pools and other collective or individual supply systems.

Convincing

It is well known that water for human consumption must meet a drinking water standard governed by law and / or ordinances of government agencies, which delimit microbiological, physical, chemical and radioactive parameters in order to avoid risks and safeguard the health of consumers.

In this context, chlorine is the most used disinfectant in the production of drinking water for human consumption, since it is an affordable component, effective on pathogenic microorganisms, and tolerated by the majority of the population since properly dosed through systems. , devices and equipment.

State of the art The vast majority of commercially known disinfection equipment does not apply to building / residential installations as their constructivity is limited to higher flow rates. Other pool treatment devices are adapted to play the role of chlorine dispensers.

The above products are generally composed of a single dosing chamber which at the same time serves as a water passageway and dilution and dosing chamber and is applicable to different commercial disinfectants.

The current state of the art anticipates some documents on chlorine dispensers such as MU 8702427-6 "Technical Arrangement Introduced in a Water Chlorinator Device" - it is a device that uses multi-layer chlorine tablets used in situations where high levels are required. concentration of this disinfectant. Basically, the device is composed of a body and basket that acts as a prefilter, a transparent display that shows the consumption of the inserts, as well as manual adjustment ball type registers and other components.

The above apparatus has a number of drawbacks, due to the difficult control of the dosage of the product in water, both by the early fragmentation of the tablets causing excess dosages of the disinfectant and the clogging of the system. In order to avoid overdose, the device uses unsafe use of registers to regulate the flow of water in and out of the product. Complementary features such as filters are needed to retain excess disinfectant, thus avoiding users intoxication, but if saturated completely losing effectiveness. Other drawbacks is the cost of replacement of filters and excessive consumption of disinfectant that is discarded together with the retaining agent.

Another alternative for dosing is the use of chlorine dispensers adapted from existing filters, in which the filter element is removed in place of chlorine pool tablets, sodium hypochlorite or other chlorine derivative. For its operation it is necessary to make a diversion so that only part of the water comes in contact with chlorine, and in this diversion is installed a record before and after the dispenser. Thus, only a technically qualified person can adjust chlorine (manually) according to the water flow, which if changed demands new regulation.

Purpose of the invention

Propose a device of simple constructivity and installation of fully automatic and mechanical operation / adjustments, without the presence of records, ensuring the dosage of chlorine for consumption in the correct proportion in accordance with the requirements of the legislation for that demand / flow.

Of the invention

The chlorine dispenser is composed of a centrally bulging main structure that has the symmetrical water inlet on one side and opposite it. Internally in the conduit is a bottleneck which forces the pressure increase to the point where the venturi is located. Adjacent to this, a second chamber sucks the chlorinated solution making the mixture, in the correct dosage, by pressure differential from where it goes to the network not before passing through a flow control valve. In the waterway, an inlet valve, also due to pressure difference, allows a portion of the fluid to pass through a hole into the disinfectant holder where it enters in contact with chlorine by forming a dissolution chamber thereafter thereafter, after passing through the upper mechanical filter, to the dispersion chamber in concentrated form, whence thereafter, after passing through the lower mechanical filter, to the outlet valve, mixing chamber, flow control valve and hydraulic network already with adequate chlorine percentage.

Advantages of the invention

Simplicity and practicality - no adjustment is required to adjust the chlorine dosage or electricity for its operation;

> Easy installation and maintenance - The user does not need specific technical knowledge to operate the product. It has adapters and fittings suitable for any piping;

> Safety - Automatic and autonomous mixing ensures dosing within the relevant standards and specifications. A flow valve prevents the return of mains water into the dispenser when not in use, which combined with the inlet and outlet valves keep the solution concentrated in the dissolution chamber.

Reliability - regularity of dosage regardless of application range. For, for example, a range of 250 L / h to 2400 L / h dosages respectively 4 ppm and 0.2 ppm.

> Versatility - with the correct size of the dissolution chamber keeping the same structure and concept it is possible to meet the flow rates of 10 L / h - 300 L / h or above 2400 L / h.

The "Solid Chlorine Dispenser for Consumption Water in General", object of this patent application, consists essentially of a dispenser (1) consisting of a main drag waterway structure (2) with an inlet (3) and an outlet (4) which frame (2) contains a chlorine disinfectant holder (5) for the chlorine tablet (6), configuring a dissolution chamber (7) which in proportion to a portion of the water coming from the inlet valve (8) generates a concentrated disinfectant solution that follows, not without first passing through solid waste filters (9 and 10) to the dispersion chamber (1 1) and hence, by pressure difference generated by the Venturi (12) in the vicinity of the mixing chamber (13), already dosed for consumption by the flow control valve (14).

More particularly, the dispenser (1) is comprised of a bulging body main structure (2), with an inlet (3) for receiving the water to be translated and an outlet (4) of the properly chlorinated water itself. the correct measurement thanks to the action of a Venturi (12), which generates a pressure difference sufficient to form a vacuum that forces the concentrated solution in the dissolution chamber (7) to pass through the mechanical filters (9 and 10) and proceed to the outlet valve (15), towards the mixing chamber (13) where it joins with the water from the inlet of the doser (1), which properly dosed passes through the flow control valve (14) and finally for consumption. Concentration of the solution occurs with the small amount of water coming from the network, which passes through the inlet valve (8) and the hole (O) taking place inside the disinfectant holder (5).

Thus, the main structure (2) serves as a means of connecting to the hydraulic network by means of suitable connections (16 and 17), also integrating the necessary components for the operation of the doser (1) with emphasis on the inlet valve (8). , outlet valve (15), flow control valve (14) that prevents water from returning to the interior of the equipment, venturi (12), dissolution chamber (7), dispersion chamber (11), mixture (13), disinfectant cup (5) in which the chlorine tablet (6) held in a transparent cover (18) provided with a cradle for the sealing ring.

In turn, the disinfectant holder (5) has the serrated top edge (19) in an ellipse-shaped shape which, in contact with the inner face of the lid (18), when closed, delimits the passage area of the concentrated solution making the role of a first mechanical filter (9) for solid waste. The disinfectant holder (5) has a pin (20) for centering and fitting to the main frame body, as well as a frusto-conical projection (21) for inserting the insert (6). At the base of the disinfectant holder cup (5) a sealing ring (22) ensures that water directs directly to the chlorine tablet (6), then passes through the filter (9) to the dispersion chamber (1). 1), and for the second serrated filter (10) formed by an ellipse shaped (23) located on the surface of the main frame body, which in contact with the bottom of the disinfectant holder (5) delimits the passage area, filtering the solid waste that goes to the outlet valve (15). Radial tappings (24) on the top face of the disinfectant holder cup (5) serve to seat the insert (6), thus freeing up space (25) for the flow of water / solution without the restrictions that would occur in this case. said tablet (6) is seated directly on the bottom of the cup.

In addition, perimeter drains (26) relieve any air that may form inside the dissolution chamber (7). The presence of air happens mainly the first time you turn on the water network.

The mixing chamber (13) joins the concentrated solution with the inlet water, which is metered through a metering orifice (27) in the outlet valve (15). Dosage control is performed by varying the orifice diameter (27). As the dispenser is subject to different water flows, the higher this flow rate the greater the pressure difference generated by the equipment that keeps the disinfectant dosage uniform.

The flow control valve (14) has the operation based on the action of a spring (28) on a ball (29), which when the rest system takes place, closing the outlet to the mixing chamber (13). Thus, as already commented, it is possible to prevent the water pressure in the pipeline in front of the doser (1) from returning, avoiding accidents when the need for joking fun (6). With the system at rest it also acts as an automatic register, since it segregates the already chlorinated water to the required standards, avoiding mixing with the raw water, which would alter the potability.

The inlet and outlet valves (8 and 15) act on a ball (29), which under certain pressure opens or closes respectively the inlet port (O) and the metering port (27) directly connected to the venturi (12). With the hydraulic network at rest, the valves (8 and 15) confine the chlorinated solution in the dissolution chamber (7) and the dispersion chamber (11), preventing spreading to the network piping.

In a constructive variation, the larger disinfectant holder (5) has a smaller displaced dissolution chamber (7), making it ideal for use in artifacts and instantaneous flow devices such as hand pumps or gravity media (tanks). This model is suitable for chlorine tablets of 20g or smaller, keeping the same components as the first explained dispenser.
