Description

Safety tray and antivertidas

Technical sector of the invention

The invention relates to a passable safety tray, especially suitable for placing a prefabricated house or building on top for storing containers of liquid, solid or pasty waste, for example port waste.

Background of the invention

In the duly equipped port areas, prefabricated sheds are used that store deposits or containers in which the waste is introduced, which is accumulated, for example, on board the vessels for the control and proper environmental management of these wastes.

These booths usually comprise a waste collection safety tray closed superiorly by a passable grid on which the tanks are placed. In case of accidental spillage of the deposits, the spilled fluid would pass through the grid and be contained by the tray. It is usual to have a prefabricated house with side walls and a cover on the grid to restrict access to tanks containing hazardous materials and comply with the applicable regulations for special and hazardous waste. However, some containers are placed on the rack but outside the booth so that they are accessible to the general public that needs to use these containers. To protect these outer containers from rain and sun, the deck of the sheds conventionally extends over this outer area of the grid, as an eave, to water the outer containers.

This eave does not prevent the lateral rain from reaching the grid placed on the tray in the area not delimited by the walls of the house and that the accumulation of water in the tray causes its overflow. This overflow of the water causes spillage of the waste collected by the tray since they are of a density lower than that of the water and therefore accumulate on the free surface of the water contained by said tray.

It is an object of the invention a safety tray for a waste storage module that avoids this inconvenience, in order to avoid contamination of the environment of the storage module.

Explanation of the invention.

The passable and antivertido safety tray of the invention, especially suitable for placing a prefabricated house or building on top for storing containers of liquid, solid or pasty waste, comprises a collecting tray on which it is arranged, elevated with respect to the bottom of the tray, a passable grid through which accidental spills of the containers placed on the grid can pass for containment in the tray.

In essence, this bucket is characterized in that it comprises a drainage zone located in an area adjacent to its contour that is provided with at least one hole to evacuate the accumulated liquids in this drainage zone, and because below the grid it is placed in the less this drainage zone is a hydrophobic / oleophilic material that absorbs mineral and vegetable oils and similar substances based on oil, such as petroleum distilled hydrocarbons, and that repels water.

The correct installation of the bucket implies its arrangement on a floor inclined towards the drainage area of the bucket.

In order to ensure its correct installation, in one embodiment the bottom of the cuvette is inclined or converges towards the drain zone. This inclination is preferably greater than 1.5 °, and more preferably 2 °.

The hydrophobic / oleophilic material acts as a filter for the waste, so that it does not prevent the overflow of water from the tray in the drainage zone but it does prevent the residues that float on the free surface of the water. In other words, the hydrophobic / oleophilic material allows water to pass through, but not the residues that will be embedded in said material, thus minimizing the risk of contamination.

In one embodiment, the hydrophobic / oleophilic material is made of polypropylene, which attracts oils and repels water.

In a variant, the hydrophobic / oleophilic material is shaped in the form of a sheet and is applied to the underside of the grid. In other embodiments contemplated, the material is in the form of pellets, non-woven fabric or in the form of rolled sheet among other possibilities.

In a variant, a second grid is placed below the sheet, the hydrophobic / oleophilic material being placed, as a sandwich, between the passable grid and the lower grid.

According to one embodiment, a part of the grid that encompasses the environment of the drain zone is collapsible or separable from the rest of the grid in order to be able to replace the hydrophobic / oleophilic material without having to discover all the tray and be able to periodically clean the bottom of the tray

Brief description of the drawings

Fig. 1 is a perspective view of a module for waste storage comprising a bucket according to the invention; Fig. 2 is a schematic view showing the arrangement of the hydrophobic / oleophilic material according to a variant of the invention; and Fig. 3 shows a detail of the bucket especially of the drain zone.

Detailed description of the invention

Fig. 1 shows a module 2 for the storage of waste comprising a tray 1 of rectangular plant formed by a bottom 3 and four walls 4 of equal height on which a walkable grid 5 is arranged that covers or closes the above mentioned tray above. one.

The module 2 comprises a prefabricated house 6 devoid of floor with side walls 7 and a cover 8 that protrudes to one side of the house 6 to form an eave 9 that protects the part of the grid 5 that is arranged from rain and sun outside the booth limits 6.

In the example, the bottom 3 of the cuvette 1 (see Fig. 3) is inclined or converges towards a drainage zone 11 located in a corner of the cuvette 1 provided with at least one hole 12 to evacuate the liquids accumulated in this zone of drain 11 to which a valve, a pipe or similar device is connected to selectively empty the water accumulated in this drain zone. In one embodiment, the inclination of the bottom 3 of the bowl 1 is approximately 2 °.

The bowl 1 collects the mixture of water and waste accidentally poured by the tanks or containers (not shown) that are arranged on the grid 5, whether they are located outside or inside the booth 6. These residues, oily in nature, float on the free surface of the water and taking advantage of this effect the hole 12 is arranged close to the bottom 3 of the bowl 1 so that when maneuvering the valve for opening the hole, water will first flow out until the level of the contents of the bowl decreases enough for the waste to descend to the level of the hole 12, at which time the operator will close the valve or collect the waste in a special collection container.

The water that accumulates the bucket 1 can be water of external origin, for example rainwater, or water originally mixed with the waste that was dumped in the containers arranged on the grid 5.

In any case, a hydrophobic / oleophilic material 13 that absorbs animal, mineral and vegetable oils and similar oil-based substances, which repels water, is placed under the grate 11.

This hydrophobic / oleophilic material 13 covers the grid 5 below in the drain zone 11 and acts as a filter for the waste, so that it does not prevent the overflow of water from the tray in the drain zone when too much fluid accumulates in this drainage zone 11 but of the residues that float on the free surface of the water. This situation can occur for example in case of heavy rain.

Preferably, the hydrophobic / oleophilic material 13 is made of polypropylene, which attracts oils and repels water, although it can be manufactured with specific resins or other materials.

In the example, the hydrophobic / oleophilic material 13 is configured in the form of a sheet and is applied to the lower face of the grid 5, firmly attached to it for example by means of ties, clamps or the like.

The invention provides that a second grid 5 'is placed below the hydrophobic / oleophilic material sheet 13 (see Fig. 2), the hydrophobic / oleophilic material 13 being located, as a sandwich, between the transitable grid 5 and the 5 'bottom grid.

As Fig. 3 illustrates, in a variant of interest, the part of the grid 5a that encompasses the environment of the drain zone 11 is collapsible or separable from the rest or other part of the grid 5 in order to replace the hydrophobic / oleophilic material 13 without having to discover the entire bottom 3 of the cuvette 1 or a significant part thereof.

5 Naturally, the grid 5 can be formed by a network of juxtaposed grilles, which are placed in the same assembly plane to form the passable floor of the tray 1.

The invention is of special application for cuvettes 1 used in storage booths or harbor waste storage. Such cuvettes 1 are generally rectangular in shape and have, for example, dimensions 2.45 x 6 m2 or 2.45 x 3.40 m2. In these examples, it is envisaged to cover the passable grid 5 in the drainage zone 11 an area of approximately 1 m2.

In combination with the invention, the containers can be arranged on individual pails resting on the grid of the safety tray. These individual buckets comprise side walls that surround the base of the container for the purpose of configuring a container to retain debris that may overflow from the container.

20 mouth of the container. The invention provides a hydrophobic / oleophilic material that absorbs mineral oils and oil-based substances and repels water in the space between the cuvette walls and the container walls, in order to retain waste of this nature that tend to overflow from the container.
