Abstract

Integrated aerator for storage and drying silos installed directly over the silo's grains unloading tunnel (1), which is used for the air captation and using the same for drying and conservation of agricultural products stored in the mentioned silo, this aerator being made-up by a modular structure (2) provided of an inferior opening for air captation (3), over which is positioned a rotor (4) associated to a rotation shaft (5) with rotation bearings (6), a set that is driven by a motor (7), in a form to capture air through the opening (3), and blowing the same through a perimeter structure of shutters (8) and exits (9), which direct the blown air directly inside the silo.

Description

TECHNOLOGICAL SECTOR OF THE INVENTION

The present invention pertains, in a general way, to the technological sector of equipments for drying and storing agricultural products, such as vertical or horizontal drying silo, and refers, more specifically, to a new conception of aerator, made-up by a modular structure, preferably metallic, which integrates the blowers to the silo's aeration caves, the mentioned aerator not requiring the execution of specific and prior civil construction work for its installation, what eases and simplifies the procedures needed for its actual installation, decreases the time used for the same, as well as the associated costs.

The storage and maintenance of agricultural products comprises a multiplicity of grains of the most different cultures, implies in decreasing the humidity and the temperature of the grains mass for the storage, in order to avoid the appearance of a series of pathogenic organisms that develop in humid environments and that could contaminate and even compromise the entire load of grains.

STATE OF ART

The state of art of this technological sector is made-up by storage and drying silos with aeration systems to obtain the drying, cooling, and conservation of grains. These aeration systems involve feeding ducts positioned on the silo's floor, which execute the air transport, from external chambers of decompression up to central distribution caves.

In particular, is mentioned the PI 0403091-5, “Direct integrated aeration system applicable in vertical and/or horizontal silos”, title belonging to the same depositor of the present request, which refers to a system with feeding ducts with built-in fans, which integrate external structures of air captation, with gravitational shutters with the internal caves of aeration, besides integrating as well the mentioned captation structures with aeration grids positioned on the silo's floor through ducts containing inlaid fans. This system also foresees the integration of aeration caves with the grains unloading tunnel, in order to capture air in the same, and distributing it on the grains mass.

NOVELTY AND OBJECTIVES OF THE INVENTION

The invention presented in this descriptive report views to characterize a new conception applied to an integrated aerator for storage and drying silos, which provides greater efficiency and, principally, simplifies the installation procedures, made-up by a modular metallic structure, which integrates the blowers with the aeration caves, installed above the grains unloading tunnel, therefore, without being necessary to execute substantial civil engineering work besides the execution of the mentioned tunnel's linking opening, to enable the same to be used as air duct for the transport of air for the drying and conservation of the grains mass stored in the silo, which will be captured by the aerator and blown inside the drying silo.

DETAILED DESCRIPTION OF THE INVENTION

As it can be seen on the annexed Figures, the integrated aerator for drying silos presented in the present descriptive report is installed directly over the grains unloading tunnel of the silo (1), which is used for capturing air and using the same for drying agricultural products stored in the mentioned silo, this aerator being made-up by a modular structure (2) provided with an inferior opening for air captation (3), over which is installed a rotor (4) associated to a rotation shaft (5) with rotation bearings (6) a set that is driven by a motor (7), in order to capture air through the opening (3) and blow the same through a perimeter structure of shutters (8) and exits (9), which direct the blown air directly inside the silo.

The present descriptive report presented a new and original invention, of industrial application and inventive activity, with all requirements to receive the concession of the demanded privilege.
