Definitions
- the present specification refers to a self-cleaning filter perfected for agricultural irrigation water, in which a series of improvements introduced in the self-cleaning filters intended for water cleaning are verified, in which the self-cleaning process is carried out by means of temporary immersion of the flow direction or the water that flows through it, reducing the consumption of water from cleaning, periodic maintenance operations, manual cleaning and high manufacturing costs.
- This invention has its application within the industry dedicated to the manufacture of filters for water, and especially for irrigated water.
- self-cleaning filters have long been known and used in those that, from a substantially cylindrical casing, two coaxial chambers, one perimeter and the other axial, are established inside it. related to each other through a plurality of filtering discs provided on their faces with grooves, which are sometimes radial and sometimes oblique, so that when these discs are superimposed on each other, the aforementioned grooves become conduits of reduced caliber, which are what give these filters the filtering effect.
- the corresponding water inlet is coupled to the surrounding or external chamber, while the axial chamber is in turn connected to the outlet for the filtered water, generally in an axial arrangement, in such a way that the suitably pressurized water reaches the perimeter chamber first, so that through the discs it reaches the axial chamber, producing its filtering, and finally leaves the filter through its axial outlet.
- Flow reversal is also known through a three-way valve coupled at the water inlet to the filter.
- the water particles are of light or floating matter, such as, for example, algae remains, they make cleaning more precarious due to the aforementioned, as they do not have a flow or cleaning speed, and as a consequence of the reduction flow throughout the cleaning phase, forcing more water to be wasted to shorten cleaning operations.
- the self-cleaning filter perfected for agricultural irrigation waters solves the aforementioned problems in a fully satisfactory way.
- the self-cleaning filter perfected for agricultural irrigation waters object of the invention is composed of a basic structure, similar to other filters of this type, consisting of an external chamber to which the water inlet is attached, inside which It locates an axial chamber that communicates with the outlet duct or mouth, both chambers being defined by a disk frame, and the inner chamber constituted by the interior of the filtering discs or rings.
- One of the characteristics of the present filter consists in the incorporation of an outlet for the water coming from the cleaning in the outer chamber independently of the one used as the inlet to the filter, making this outlet possible to pre-clean the rings at a faster flow rate. circulating for cleaning, eliminating all the particles in suspension, first opening the outlet of new incorporation, it is achieved that the water entering the filter sweeps the larger particles adhered to the rings on the outside of them , and in a short time, the water inlet to the filter is closed, this causing the flow to be reversed, cleaning the internal part of the rings by means of the water coming from the perforated tubes.
- This filter differs substantially of the filters currently used in the fact that it presents the possibility of making a 'self-closing, by reversing the flow, ensuring that the water passes only through the perforated tubes and the rings are separated at the same time, these two effects being dependent on each other according to a base on which the rings rest, forming the package that is crossed internally by four tubes that form the chassis of the rings, which are supported on these tubes and they are finished at the top in a circular piece that acts as an upper stopper for the rings, which has an external diameter measurement similar to that of the rings to which they are detachably attached to the four tubes.
- these pass through the base by means of holes larger than the diameter of the tubes, in order to achieve free movement and ending these tubes in a circular piece that leaves free the holes that They form the tubes and being fixed to them, they allow to make the closing effect of the water passage by reversing the flow and separating the rings at the same time.
- the entire invention is by default in the sense of pressing the rings by means of a spring located at the bottom or base of the rings, configuring the self-closing means.
- this filter lacks gaskets and membranes or any other means that causes periodic maintenance and a low manufacturing cost due to its minimal use of construction parts.
- Figure number 1 Corresponds to a side elevation view, partially sectioned, of the object of the invention corresponding to an improved self-cleaning filter for agricultural irrigation water in rest position.
- Figure number 2. Shows a fully sectioned view and in the same position of the object reflected in figure number 1.
- Figure number 3. Shows a view of the object reflected in figure number 1 in the filtering position.
- Figure number 4. Reflected in a fully sectioned view of the object in the same position as that reflected in figure number 3.
- Figure number 5. Represents a view of the object shown in figure number 1 in the cleaning position.
- Figure number 6. Corresponds to a sectional view and in the same position of the object reflected in figure number 5.
- the self-cleaning filter perfected for agricultural irrigation water is constituted from a cylindrical casing (1) that has an internal hollow area (2), to which a mouth (11 ) of waters to be treated radially, and a second mouth (12) coupled axially for the outlet of the filtered water, incorporating into the casing (1) a cover duly supported by a metal clamp or the like.
- a cartridge (3) formed by a set of grooved rings duly pressed axially, and said cartridge (3) is the one that defines inside the " casing (1) two chambers, an exterior for dirty water (2) and an interior for filtered water.
- the water enters through the inlet (11), passing through the rings (3) properly pressed, leaving the particles in it, and passing the clean water to the interior chamber, accessing through the outlet (12) axial.
- the flow is reversed by accessing the axial (12) or internal chamber and exiting through the dirty water inlet, and in this flow reversal the mechanisms that separate the rings and act the reduction of flow, leaving access only through perforated tubes that impinge on the rings, making them turn at the same time by their pressure jets, achieving cleaning.
- the invention incorporates an upper cover (5) located on the set of rings (3) that make up the filter cartridge and a support base (8), as well as a spring (7).
- the filter has an additional radial opening that communicates with the outer chamber (2), which will be used as the outlet for water from cleaning, so that the flow or, when reversed, will exit through it, allowing a Total independence of the inlet (11) of dirty water with the outlet (10) of cleaning water, achieving that the filter reaches a higher flow rate or cleaning at the beginning, eliminating the larger particles and not carrying out the separation of the rings (3) until the total closure of the dirty water to filter that enters through the mouth (11), achieving that when going back to the filtration state, the cleaning outlet (10) is closed first, achieving that the rings (3) are pressed, and when they are in this situation, open the inlet (11) of water to be filtered.
- the cartridge (3) is made up of four round bases (5), (6), (8) and (9) and four perforated tubes (4), as well as a spring or spring (7) and a regulating screw.
- the tubes pass the lower base (9) through four perforations, with freedom of movement, having the spring (7) located in the lower base (9) and the circular or round base (6), and exerting a pressure according to the flow direction, achieving the change in the situation of the rings (3), the pressure and the decompression.
