ADAPTATION AND IMPROVEMENT OF AN EXISTING DOMESTIC WATER FILTRACTION DEVICE FOR EXTRACTION BY DISSOLUTION IN THE WATER OF SOLUBLE PRODUCTS CONTAINED IN WATERPROOF WATERPROOF.

. \ GENERAL DESCRIPTION OF THE INVENTION

Adaptation and improvement of an existing household water filtration device for the extraction by dissolution in water of soluble products contained in

water soluble wrap.

10 Technical sector

The invention is part of the technical sector of water filtration processes for domestic use, as well as by garden professionals. 15 State of the art

There are currently different water fertilization devices. In all God the excessive complexity for the domestic user is evidenced, as well as a solubility

20 excessively fast. US2004 / 0232163 discloses a device that allows to precisely control the weight of a powdery fertilizer incorporated into a liquid flow through the use of a gravimetric sensor. This device is complex and expensive, not being suitable for the small non-professional user. Moreover, the use of

25 pre-dosed and pre-packaged portions of fertilizer for the subscriber of all types of crops and gardens through irrigation water have the advantage of facilitating maintenance and fertilizer operations, saving labor and problems with the application of organic matter (method traditionally used), which causes bad odors and the appearance of weeds, while ensuring quality constancy

30 of l fertilizer. Document US4333493 poses as a problem the excessive complexity of the devices that incorporate the fertilizer into the irrigation water stream precisely, and based on the idea that this high formulation precision is unnecessary for most applications, proposes the use of a disposable cartridge

35 truncated conical shape that contains the fertilizer in granular form. The base of the cartridge has a calibrated hole for water inlet and a plurality of perimeter outlet holes. Both the inlet and outlet holes remain covered until the moment the cartridge is used by a self-adhesive sheet, which must be removed manually.

40 Document US4901890 raises the problem of early release of fertilizer by the aforementioned devices in automatic irrigation systems. The proposed solution consists in the use of a closed cartridge by means of a membrane that is perforated by a hollow needle driven by the irrigation water when pressurizing the circuit. In this way, the sealed cartridge does not let its contents escape until the moment of

45 watering. Once the membrane is perforated, the irrigation water is injected inside it through the center of the needle, the fertilizer solution being extracted perimetrically. This system requires the use of special plastic containers that a

Description of the invention

The objective of the invention is to propose the adaptation and improvement of a device

Conventional water filtration for domestic use that allows the extraction of a soluble fertilizer contained in a water-soluble envelope without generating a residue from the empty container, avoiding contact with the product that is produced in the mechanism, guarantees the total extraction of the fertilizer thanks to the complete dissolution of the wrapper and an effective water circulation through it, in addition,

30 incorporates a pre-injection filtration system to the irrigation system, and facilitates the filling and cleaning of the device by means of a threaded opening and closing system. The total extraction is produced by means of dilution in the irrigation water, and for any irrigation system, of water-soluble containers and the nutritive substance it contains. Water-soluble containers must contain at least one nutritive substance (e.g.

35 nitrogen, phosphorus, potassium, calcium, magnesium, iron, etc.) for any type of ornamental plant, lawn or crop. The water-soluble container is a cold water soluble film that forms a bag containing the fertilizer. Those that are degraded or solubilized due to the action of moisture or water are considered hydrobiodegradable or water-soluble containers. He

The water-soluble container would be a cold water soluble film that meets at least the biodegradation rate according to the requirements of the UNE · EN ISO 14851 standard. The recommended water-soluble package is based on the patent 4544693 ("Water soluble film") composed mainly of polyvinyl alcohol (PVOH) that is recommended for agricultural products.

45 The nutritive substance or fertilizer is solid, soluble in water and of mineral composition (eg calcium nitrate, potassium nitrate, monoamonic sulfate, etc.) can be powdery, crystalline, micro granulated, granulated or appropriately compacted in One or several pieces. The device is composed of two transparent glasses (3) with plastic head and threaded connections (2), one with an inner container (4) that will contain the product (water-soluble container and nutrients) with openings in the base (S ) for water inlet, and in the upper part (6) for the output of the product or water; and the second glass with a filter (9) where the product + water will pass. The procedure is to drag the

product contained in the container of the first vessel by entering water through the bottom of the container (4), which dissolves the fertilizer wrap, and drags the dissolved fertilizer (6), proceeding to its evacuation (8) to the next vessel , and finally product + water passes through a filter (9) before joining the irrigation (10). The device incorporates as novelty a thread system (7) in the upper part of the container of the ferlilizer (4) that allows to incorporate the product with ease; a filtering system (9) prior to the final injection avoiding obstructions of the system, and allowing the use of a water-soluble envelope that does not generate waste at the end of its life and protects from its contact.

Detailed description of the invention

An embodiment of the invention will now be described, as an illustrative and non-limiting example thereof. For the best understanding of what is described herein, some drawings are attached in which, by way of example only, figure 1 and figure 2 are included. The device is comprised of two semi-transparent vessels (3) of variable size with gaskets each with plastic head and threaded connections (2), one that contains a container (4) for fertilizers with openings as a grid at the base (5) for water entry, and at the top ( 6) for the output of the product + water; and another glass (3) with a filter (9) inside. The container that contains the container with the nutritive substance (4) incorporates a thread system at the top (7) that allows it to be opened and closed easily. The procedure consists in dragging the soluble product contained in the first vessel (4), for this purpose water procedent.e is introduced into the device of the main irrigation pipe (1), the water is forced to enter through the base of the container

(5) what produces a dissolution of the envelope and of the product (fertilizer), and the subsequent dragging of the same by the top (6), proceeding to the evacuation of the liquid (water + dissolved product) (8) towards the next body of the device (3), then the product dissolved in the water passes through a filter (9) before being incorporated into the irrigation system (10), preventing obstructions of the system due to bad dissolution and / or bad product quality. The procedure does not require any particular requirement regarding the flow of water in the main irrigation pipe, or any type of energy source, when the fertilizer dissolves due to the pressure generated inside the container and the mechanical action of the passage of water. The system facilitates the total solubility of the fertilizer due to the pressure generated inside the vessels of the device. The use of water-soluble containers that completely envelop the product prints greater security in its application since it avoids direct contact with the chemical substances that make up the fertilizer; and does not generate waste (plastic containers, Maya, etc.) since the packages dissolve

Totally in the water. Those that are degraded or solubilized due to the action of moisture or water are considered hydrobiodegradable or water-soluble containers. the incorporation of a filter prior to the exit of the dissolved product prevents the clogging of filters and irrigation systems. The vessels are semi-transparent to control

5 the status of the remaining product and the filter.
