PREFERRED EMBODIMENT OF THE INVENTION

In view of the mentioned figures and according to the numbering used, a preferred embodiment of the tubular filter of the invention, comprising that indicated and described in detail below, can be observed in said figures.

Therefore, as observed in said figures, the filter (1) in question is formed in a known manner by a cylindrical tube of plastic mesh (2), closed at both ends with respective hermetic caps (3), which internally incorporates granulated materials that absorb ethylene or other gases, and it is essentially distinguished by the fact that said mesh (2) has a structural configuration which facilitates the entry of air flow into the tube, being formed by the combination of an inner crown (20) formed by filament having a circular section (201) and an outer crown (21) formed by a filament which, instead of being circular, has a wing-shaped section configuration (211), wherein the circular base thereof is wider than the distal end thereof (FIGS.1to5).

In the preferred embodiment, said tube of mesh (2), which is made of a plastic material as mentioned, being produced by a horizontal extrusion system rotating counter-clockwise and with air cooling, preferably has dimensions with an outer diameter (d) of between 40 and 55 mm and a length (l) of between 50 and 150 cm, wherein the circular filament (201) of the inner crown (20) preferably has conventional measurements, i.e., a radius (r) of 0.5 mm, whereas in the outer crown (21), the base of the wing-shaped filament (211) also has a radius (r) of 0.5 mm, the upper part has a radius (r) of 0.15 mm, and the distance (di) between the center of both is 2.30 mm, the total height (a) of said wing-shaped filament (211) being 2.95 mm, as shown inFIG.5.

The preferred material of the plastic mesh (2) is HDPE (high density polyethylene), combined or not combined with glass fibre, but there can also be another type of material. Optionally, however, it can also be manufactured from biodegradable materials biodegradable such as PLA (polylactic acid).

Optionally, the filter (1) comprises a support accessory (4) which is installed in a fixed manner on the grating of the container for which the filter (1) is intended, allowing for a successive use, since it can be readily incorporated in and removed from same, which considerably facilitates the operation of installing and changing the filter (1). In addition to serving as a support, this accessory also helps to increase air flow through the filter (1) even further due to its aerodynamic shape, and to prevent accidents due to staining the load by means of its liquid collection system.

To that end, as observed inFIGS.1and6, said support accessory (4) consists of an elongate element made of plastic material which incorporates respective anchors (40) at the ends thereof suitable for being adapted to the different diameters and lengths of the filter (1), and between which there are provided two longitudinal parts, an upper longitudinal part (41) and a lower longitudinal part (42) between which the filter (1) is arranged, having an approximately planar configuration, causing them to function like ‘wings’ forcing the air to pass through the filter (1).

In the preferred embodiment, said anchors (40) are formed by respective C-shaped parts suitable for receiving the caps (3) of the ends of the tube of mesh (2) of the filter (1), providing an adjustable closure (401) which, by way of a flange that can be inserted into an eyelet (402), serves to secure the holding of same.

Furthermore, the inner face (421) of the longitudinal part or lower wing (42) defines a passageway serving to collect the liquid which may accidentally form in the filter (1), albeit very rarely.

Likewise, at least at one end of the support accessory (4) there is provided an opening (43) which communicates with said inner face (421) of the lower wing (42) and which, by means of inserting a hose (not depicted), can be connected to a collection vessel for said liquid (FIG.6).

In the preferred embodiment, the filtration means contained inside the tube of mesh (2) of the filter (1) consist of spherical granules or pellets formed from a natural, highly pure clayey base and potassium or sodium permanganate with or without active charcoal, although it can contain any type of granules.

Likewise, the filter (1) can have any of the weights and sizes within the usual range of tubular filters that absorb ethylene or other gases; however, the preferred size is 120 cm and the preferred outer diameter is 55 mm for containing 2 kg of granules, since this format can replace a currently more widespread practice of using 2 tubular filters measuring 1 meter and 1 kg of granules in the grating of the container, thereby reducing the amount of plastic material forming same and, accordingly, the waste generated once its service life has ended.

Having sufficiently described the nature of the present invention as well as the manner of putting it into practice, it is not considered necessary to expand on the explanation so that any person skilled in the art can comprehend its scope and the advantages derived from same, whereby stating that, within its essential nature, it may be carried out to practice in other embodiments that differ in detail from the embodiment indicated by way of example, and it will likewise receive the protection that is sought provided that the fundamental principle thereof is not altered, changed, or modified.
