Description

Field of technology to which the utility model belongs

The utility model relates to aqua vending machines, i.e. to vending machines for drinking water obtained both from tap water that has undergone multi-stage purification using reverse osmosis and disinfection, and taken from a well, so that for both it is desirable, and in some cases a certain modification of this water is necessary in order to give water certain consumer properties (mineral composition, organoleptic properties, taste, pH). Specifically, the utility model relates to said modification carried out directly in the stream directed to the water buyer.

State of the art

The need to improve the consumer properties of water in some cases arises in relation to water from a well, and different wells require different modifying additives depending on the initial parameters of the water. At the same time, it (this need) always arises in relation to water from the water supply due to the use of reverse osmosis for its purification.

As is known, in the process of aqua vending of drinking water obtained from tap water, tap water is filtered, disinfected, separated into permeate and concentrate using a reverse osmosis membrane, the concentrate is sent to the sewer, and the permeate thus formed turns out to be low mineralized. For this reason, additional permeate mineralization, more broadly, modification is carried out by adjusting its properties (mineral composition, organoleptic properties, pH). After that, the modified permeate is disinfected with ultraviolet light and, at the request of the buyer, is fed into the buyer's container in a given amount. At the same time, the specified modification of the permeate is carried out in the permeate modification module, in which the permeate sequentially passes through three blocks: the mineral composition modification block, the organoleptic properties modification block and the pH modification block (see the description of the invention according to patent RU No. 2767311 C1, IPC C02F 9/00 , G07F 13/00, published 03/17/2022 Bull. No. 8).

The reason preventing the achievement of the claimed technical result in the known device lies in the passive nature of the modification of the permeate, which consists in the fact that the introduction of modifying additives into the water is carried out from the solid fillers of these blocks due to the natural (passive) diffusion of substances from the solid into the water.

The prototype is a device containing a pipeline for transporting the flow of water issued to the buyer, a flow meter for measuring the flow of this water, as well as a source of modifying additive hydraulically connected to the pipeline, which is a diffusion-type mineralizer cartridge (see the description of the utility model to patent RU No. 139649 U1, C02F 9/00, published on 20.04.2014 Bull. No. 11).

The features of the known device (prototype), which are common with the features of the device claimed for patenting, are that the known device contains a pipeline for supplying water to a water buyer, a flow meter for measuring the flow of this water, and a source of a modifying additive.

The reason that prevents obtaining the claimed technical result in the known device (prototype) is that it uses a mineralizer cartridge containing a fixed amount of solid granular filler as a source of modifying additive, which, due to passive diffusion, is an uncontrolled and uncontrolled source of modifying additive . For this reason, the qualitative and quantitative indicators of such water are definitely not known to either the seller or the buyer, but can only be assumed. In addition, such a source of modifying additive is subject to natural "wear", which leads to an uncontrolled change (decrease) in time, quantitative indicators of water salinity during the time of use of a particular mineralizer cartridge.

The technical problem to be solved by the technical solution claimed for patenting is the need to ensure the exact value of the qualitative and quantitative parameters of the modified water (mineral composition, organoleptic properties, taste, pH) directly issued to the buyer of water, ensuring the invariance of these parameters over time, if there is no order for the water buyer to change them, providing the possibility of changing these parameters under the order of the water buyer (within the normatively permissible limits).

Disclosure of the essence of the utility model

The technical result, mediating the solution of this technical problem, is to provide forced (active, adjustable) and accurate dosing of the liquid modifying additive introduced into the water, and the composition of this additive is known and constant (invariant in time), directly into the flow of water issued to the buyer, which guarantees to the buyer of water both the composition of the modification components in the purchased water declared by the seller, and their (components) percentage. At the same time, the high accuracy of the indicated dosing is ensured by the use of a hose (i.e. peristaltic) pump, known for high dosing accuracy due to its certain design features: it is a volumetric pump with a working body in the form of an elastic hose pinched by rollers, in which the liquid medium moves by periodically changing the volume of the chamber it occupies, which alternately communicates with the inlet and outlet of the pump - see GOST ISO 17769-1-2014 "LIQUID PUMPS AND INSTALLATIONS", Appendix B (informative), paragraphs B. 1.21 and B. 1.35).

The technical result is achieved in the device claimed for patenting by the fact that it contains a pipeline (1) for transporting the flow of water issued to the buyer, a flow meter (2) hydraulically included in the rupture of the pipeline (1), a source (3) of a modifying additive, while the pipeline (1 ) is made with a side branch (4), the source (3) of the modifying additive is made in the form of a reservoir for the liquid modifying additive, the device, in addition, additionally contains a switch (5) to start the water modification process, a peristaltic pump (6), as well as a control unit (7), the inputs of which are electrically connected to the flow meter (2) and the switch (5), and its output is connected to the peristaltic pump (6) via its power supply circuit, while the hydraulic inlet of the peristaltic pump (6) is hydraulically connected to the source (3 ) modifier, and its hydraulic outlet - with a side branch (4).

Brief description of the drawings

In FIG. 1 shows a functional diagram of the inventive water modification system in the process of issuing water to a water buyer, in which the outlet of the modifying additive supply pipeline (4) is directly hydraulically connected to the water supply pipeline (1); in fig. 2 shows a functional diagram of the claimed water modification system in the process of issuing water to the water buyer, in which the modifying additive supply pipeline (4) does not have a direct hydraulic connection with the water supply pipeline (1).

Implementation of the utility model

A device for modifying water in the process of issuing water to a water buyer (Fig. 1) contains a pipeline 1 for supplying water to a water buyer, a flow meter 2 for measuring the flow of this water, a source 3 of a liquid modifying additive (i.e. a tank containing a liquid modifying additive, which is liquid mixture of components: sources of minerals, components that improve the organoleptic and taste properties of water, as well as components that change the pH of water in the right direction, if necessary), pipeline 4 for supplying a liquid modifying additive, directly hydraulically connected to pipeline 1 at the entry point 8, switch 5 to start the water modification process, a hose (peristaltic) pump 6 designed to supply a liquid modifying additive to the water supplied to the buyer from a source 3, a control unit 7 (controller) to control the specified supply of a modifying additive, the inputs of which are connected to a flow meter 2 and a switch 5, and the outlet is with pump 6.

Switch 5 is usually a button on the front panel of the aqua vending machine.

The peristaltic pump 6 is characterized, as is known, by a significant accuracy in dosing the liquid, and in this case, the liquid modifying additive through the pipeline 4.

Pipeline 1 in the embodiment of FIG. 1 is a pipe with said entry point 8, through which the modifying additive enters pipeline 1 and which can be located at the beginning (closer to the inlet), in the middle or at the end (closer to the outlet up to the outlet) of this pipe, regardless of whether where the flow meter 2 is installed in pipeline 1.

Pipeline 1 in the embodiment of FIG. 2 does not have an entry point 8, so that the modifying additive through pipeline 4 enters directly into the container of the water buyer, where it mixes with water supplied through pipeline 1. At the same time, the outlet pipes of these two pipelines, from which water and the modifying additive directly enter the container the buyer of water, can be located parallel to each other, or axially (pipe in a nozzle).

The operation of the device for modifying water in the flow of water issued to the buyer is as follows.

The source water for modification (purified water) can be taken from a well or obtained from tap water using reverse osmosis. In any case, this is already purified water, which by definition is relatively low mineralized, and as such, being suitable for consumption by its composition, it can be directly and directly supplied through the pipeline 1 to the water buyer, if the water buyer is satisfied with this low mineralized water. In this case, the peristaltic pump 6 (and hence the whole device) does not work, since the water buyer in this case does not activate the switch 5 and, therefore, does not start the water modification process.

If the buyer of water needs water enriched with appropriate additives (modified) that costs more, then, having paid for the purchase of this enriched water, using switch 5, he launches the corresponding control program in the control unit 7. This program, when launched, carries out operational management of the modification process water directly in the flow of water supplied to the buyer, moving through the pipeline 1.

This process proceeds as follows.

Measured by volume, the flow of water supplied to the buyer moves through the pipeline 1 and passes through the flow meter 2, due to which at each moment the control unit 7 "knows" the current value of the water actually passed through the flow meter 2. At the same time, the control unit 7 has such a control program that generates a control pulse (or a series of pulses), which includes for a certain time, namely, for the duration of the control pulse (pulses) the peristaltic pump 6, which in the process of its operation through the pipeline 4 and the point input 8 (Fig. 1) delivers directly into the flow of water flowing through the pipeline 1, the dose (or a number of doses) of the modifying additive (the entire dose or parts with distribution in time), taken from the source 3. In this case, the quantitatively indicated dose of the modifying additive is regulated both by the duration of the control pulse and the performance of the peristaltic pump 6 by changing the voltage of its power supply. At the same time, the modifying additive, introduced in this way into the flow of water moving through pipeline 1, is captured by this flow, and this water, together with this modifying additive, enters the container (container, bottle) of the water buyer, where, due to its high turbulence, the modifying additive is evenly distributed in volume of this water.

In the variant in FIG. 2, the modifying additive through pipeline 4 enters directly into the container of the water buyer, where it mixes with water supplied through pipeline 1.
