    System for loading, unloading, transport and storage of powdery products
    or fibrous
    Object of the invention.
    The present invention relates to a system for loading, unloading, transporting and storing powdered or fibrous products that allows the elimination of dust by reducing the risk in ATEX areas (atmospheres with risk of explosion), working with better health conditions and optimizing transport of fibrous products that, when compressed directly, reduces costs.
    Field of application of the invention:
    This system of loading, unloading, transport and storage is applicable in machines used in areas where they are handled or work with powdery products, where compliance with ATEX regulations is required and avoid atmospheres harmful to human or animal health.
    This system is also applicable to fibrous products transport devices, since when compressing fibrous products, it allows to transport a greater quantity of product and reduce the cost of transport.
    This system can be used with products such as flours, powders, granules, animal feed, fibrous products (straw, oat hay, alfalfa, ...), sawdust, chips, among others.
    Background of the invention.
    There are systems that try to eliminate the dust generated in loading, unloading, transport and storage operations of powdery or fibrous products. In most cases, these systems use suction and cyclone procedures for loading and unloading materials. In the case of aspiration, it is circulated jointly, inside the ducts installed in the
    5 ships, air, dust and product, the dust being extracted from this mixture throughCyclones or filter sleeves.
    The previous systems are usually used in factories or facilities where large quantities of products are handled, their use being scarce in
    10 small facilities due to the required investment. This entails in these facilities, normally, the breach of the ATEX regulations, leaving the facilities and personnel exposed to a risk.
    As for transport, there are also packaging systems that facilitate it.
    15 These systems are based on the compression of said fibrous products through balers. When the product arrives at the destination, on some occasions, it is more convenient that it was not packed and its unpacking becomes mandatory. In these cases, the price of the product increases without increasing its added value.
    In document DE3138131 it refers to a system for supplying a ground solid fuel to a gasification plant. The material is delivered dosed from a chamber where it is stored to a degassing chamber. This dosage is carried out by means of two endless screws
    25 successive where the first feeds the second. This set has a fire safety gate that closes by means of a spring fired by a thermal fuse.
    In document US3735932 a transfer device of a
    30 material from a milling and which is driven to an endless screw inside a cylindrical conduit that conducts the ground product to another compartment. This device requires an extractor that collects the finest particles inside the chamber where grinding is carried out and redirects them to a cyclone where said fines are deposited and then discharged at an intermediate point of the length of the transport element constituted by the anterior worm screw inside a cylindrical conduit.
    Therefore, the object of the present invention is to solve the raised problems of dust generation and unhealthiness and reduce the unit cost of the fibrous products transported, developing a system like the one described below and whose essential characteristics and mode of application They appear in the first claim.
    Description of the invention
    The loading, unloading, transport and storage system of powdery or fibrous products object of the invention that provides a series of advantages in relation to health, providing an atmosphere in which the suspended dust is remarkably reduced, and safety by avoid the formation of potentially flammable or explosive indoor atmospheres.
    A first objective of the invention, unlike the aforementioned background, is to cause a compaction of the product to be handled, so that it is compressed without air, reducing the risk of creating areas with explosive atmospheres.
    This system provides different advantages of use among which it is worth mentioning: -the evasion of dust for compliance with the ATEX regulations and health of work areas; in the loading, unloading and storage of powdery products, -and the compression of fibrous products to optimize the loading and transport capacity (greater quantity of product in the same space) and reduction of the cost per transported unit.
    According to the invention, the system comprises: a product reception area, whose function is to receive the powdery or fibrous product to be treated; -a compactor device of the product fed directly, or through an intermediate treatment device, from the product reception area; said compactor device comprising a compression zone of the product and an outlet of the compacted product; and - product discharge area provided with a lower area where the exit of the product is arranged
    5 compactor device, so that the product supplied by said outputit is stacked on the exit itself minimizing the release of dust and guaranteeing thegeneration of a pressure or retention force of product from thecompactor device
    10 It is envisaged that the product receiving area may be an outdoor area,
    or be airtight, being for example a hopper provided with a venting system.
    The compression zone of the compactor device functions as a resistor 15 for the compression of the product and as a connection component between the compactor device and the discharge zone.
    The compactor device is provided with a pressure regulator that limits the maximum pressure exerted by said device on the product in question;
    20 being its function to press the product and extract the air.
    In the discharge zone, either in an outdoor area or in a container, it is where the product is decompressed and stacked or extended due to the pressure exerted by the compression system.
    In an embodiment of the invention, the outlet of the compactor device comprises a directional hose for directing the product to the different discharge compartments and preventing the free fall thereof from the compression zone to the discharge zone at the beginning of the process.
    The operation of the system is as described below: once
    introduced the product in the cavity or hopper of reception, this is falling by
    gravity on the compression element. This element will press said
    product, which will allow the expulsion of air, and will move it towards the compression zone.
    The compression zone causes the product to be pressed, by the resistance of the conduit or zone itself and the resistance exerted by the stored product. This pressure is increasing depending on the product stored, the greater the amount of material, the greater the retention and the greater the pressure.
    The product passes from the compression zone to the discharge zone (through a directional hose that prevents free fall).
    In this last zone, the material is decompressed, without generating dust, and it moves through the entire prepared discharge zone due to the pressure exerted by the unloaded material.
    There are two possible unloading areas: outdoors or in a container. The difference between the two will be the degree of final compression of the material.
    In the case of an outdoor discharge zone, the product decompresses and moves until it occupies the prepared surface, leaving the material less compacted than in the case of the container discharge area, where the product is pressed against the walls of the container , to greater compression.
    Thanks to the system described, the evasion of dust and the healthiness of work areas are achieved on the one hand; in the loading, unloading and storage of products; and on the other hand, when the unloading is carried out in containers and thanks to the compression capacity of the system it is possible to transport larger quantities, thus reducing the unit cost of the product transported.

    Preferred Embodiment of the Invention
    In figure 1 the system for loading, unloading, transporting and storing powdered or fibrous products comprises a reception area (1) of the product constituted in this case by a cavity or hopper that has an endless (11) mobilizer of the product a try; and a compaction device (2), which presses the product at the same time that it extracts the air and moves it towards a compression zone (22).
    The compactor device (2) is driven by a stress transmission with a pressure regulator (21) that limits the maximum pressure exerted on the product.
    The compactor device (2) is fed from the reception area (1), through an intermediate device (3) for treating the product, which in this case is represented by a chopper device (3) for the product.
    This chopper device is provided with two screens (31), input and output, to allow the product to pass from the hopper (1) to the chopper device (3) and from the inside of it (3) to a collector of drop (32), which connects it with the compactor device (2), that this case is an endless screw with the appropriate characteristics for the product to be compressed.
    The screens (31) serve as a venting zone, where the deflagration (inflammation of the product) would dissipate if it occurs.
    This compactor device (2) also functions as a retainer in case of a deflagration in the drop manifold (32).
    Finally, the product is discharged outside through an outlet (23) constituted by a directional hose that directs said product to the discharge zone (4) and will prevent its free fall from the compression zone (22) to the download zone (4) at the beginning of the process.
    As can be seen, in this figure 1, the discharge zone (4) is exterior.
    Figure 2 shows an alternative for loading and unloading the product, in this case hay or fibrous products. In this case, the product is incorporated into the cavity or hopper that forms the reception area (1) by means of a load elevator (5) directly from the ground or the surface of the field to the hopper (1).
    In this embodiment, the unloading zone (4) is a container trailer so that the unloaded product is filling the container until it is compressed inside, due to the pressure exerted by the compression element (2). Said compression facilitates the transport of a greater quantity of product, thus reducing the unit cost of said product.
    Once the unloading in the container trailer is finished, it is separated from the compression zone (22) for transport.
    In this case, the driving element is a tractor, although in no case is it intended to be a limiting component.
    In Figure 3 an embodiment similar to that of Figure 2 is observed, where the product is loaded directly by a load elevator (5) from the field surface. This alternative of operation will be used when it is not necessary to chop the product, therefore, in Figure 3, the products are collected directly from the ground by the load elevator (5) and incorporated into the compression element (2), which moves them towards the compression zone (22). Finally, the product falls into the unloading zone (4) or container trailer, in the same way as in Figure 2.
    Figure 4 shows an embodiment similar to that of Figure 1, without the intermediate device (3) and in which the receiving area (1) is constituted by a delivery trailer that directly feeds the compactor device (2), which compresses the product and circulates it through the directional hose (23) towards the discharge zone, without producing dust.
    Figure 5 shows a piston cycle device as a possible embodiment of the compactor device (2) when higher pressures are required.
    The compactor device (2) has in this case a compression piston
    (24) actuated by a hydraulic cylinder (25).
    5 Its operation is similar to that of the auger, the product is pressed to thesame time that it draws the air and moving it towards the compression zone (2).
    The piston cycle compactor is operated by a distributor (26) with pressure switches (27) to adjust the pressure of both compression and return. Finally, the product is injected into the discharge zone (4) which in this figure is a container.
    Figure 6 shows a variant of the compactor device (2) consisting of an auger with the characteristics appropriate to the product to be compressed. This
    15 endless, it presses the product at the same time that it extracts the air and moving it towards the zone of compression (22). The auger, which acts as a compacting device (2), operates driven by a pressure transmission with pressure regulator (21) that limits the maximum pressure exerted by the product.
    20 The auger also functions as a retainer in case of a deflagration in the fall manifold (32).
    Once the nature of the invention has been sufficiently described, as well as a
    For example, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration of the essential features of the invention claimed below. .
