Description

Wind extractor

Object of the invention

The present invention relates to an extractor wind power intended for application in industrial buildings as well as in single-family homes, neighborhood communities, centers commercial, hotels and in general in any space you need be ventilated, and can also be used to evacuate fumes In case of fire. The extractor is based on the provision in vertical of its fins, in an established rotation bearing superiorly and in a superior aerodynamic protection cover, with the object of the latter that the bearing is not in contact direct with stale air and / or gases that it extracts, or with breezes of air, providing very advantageous features.

The object of the invention is to provide a wind extractor with the basic characteristics above referred, which is simple, effective, long lasting and minimal maintenance.

Background of the invention

Numerous types of extractors are known for the extraction of stale air from enclosed spaces, although with limitations regarding their diameter, due precisely to to use a spiral or ovoid vane design, so that from a certain size, that is, from a certain diameter of the neck of the extractor attachable to the tube in which it is applied, they have to Tempers are used to anchor the extractor assembly to the roof structure, and thus prevent it from being dragged by the force of the wind.

There are also electric extractors, although these have the disadvantage of being noisy, with a consumption Remarkable electric power, which is a high cost throughout of its useful life for the user, also polluting throughout that time the environment, both in noise pollution and in its energy consumption.

Description of the invention

The wind extractor that is recommended, and planned for its application in accordance with what is stated in the section "Object of the invention", has the peculiarity that its pallets are arranged vertically and fixed between a piece upper discoid or lid and a lower crown, counting both said top discoidal cap as the bottom crown, with holes anchor for corresponding lugs set in the upper and lower ends of the pallets themselves, so that the number of these will depend on the size of the extractor, and will be materialized in aluminum, in order to lighten the weight of set.

The vertical and central axis of rotation of the extractor It is supported by its lower part by a cross stand fixed on the inner side surface of the corresponding coupling neck of the exhaust assembly to the end of the chimney pipe to which it is applied, and whose cross support is complements with an intermediate support that being in solidarity with first it is projected upwards, constituting a means of passage and of support for the axis of rotation, avoiding vibrations in the extractor operation.

The bearing is located on a support and a base located in correspondence with the upper surface of the discoid lid referred to above, being fixed to it by screws or by any other conventional system, complementing itself superiorly with an aerodynamic cover that covers the whole set and with it the support with its bearing.

According to the referred characteristics, the extractor can reach diameters greater than 600 mm in what refers to the coupling neck to the chimney pipe to which apply, being able to reach up to 900 mm of neck, which in combination with the vertical arrangement of the pallets, allows effectively extract stale air in the place where it is mounted, resulting in a compact, functional and highly effective set.

Another important feature of the extractor referred to is the provision at the top of the system rotation, which allows to obtain a highly resistant set and robust, and better spin operation than extractors conventional where the rotation system is located in the part lower. In other words, the characteristic referred to above and provided as a novelty in the extractor of the invention, provides a longer duration to it and a longer interval between maintenance times, in which the medium support emerging from the cross support corresponding to the axis motor, which provides high rigidity without using tempering, giving the extractor the design feature cleansed.

Finally say that the extractor is put on operation with a minimum wind breeze, with a cost of zero energy and noise levels much lower than those defined by axial and / or electric extractors or fans.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a representation on an exploding overview of the different parts and components involved in the wind extractor of the invention.

Figure 2.- Shows an elevation view lateral, with a sectioned part, of the wind extractor of the invention.

Figure 3.- Shows a plan view top of the same wind extractor.

Figure 4.- Shows a detail of a palette vertical with the lugs for fixing between the corresponding discoid top cap and crown-shaped bottom cap circular.

Preferred Embodiment of the Invention

As you can see in the referred figures, the extractor of the invention is constituted from a plurality of vertical vanes (1) materialized preferably in aluminum, and whose number will be in accordance with the size of the extractor, vanes (1) that are fixed between an upper cover and discoidal (2) and a lower crown (3), whose lid (2) and crown (3) are affected by holes for anchoring a series of lugs (4) provided at the upper and lower ends of each pallet (one).

The corresponding drive shaft or steel turn stainless (5) is inferiorly held on a cross support (6) fixed by rivets, screws, or any means appropriate, on the inner lateral surface of a neck (7) as coupling means of the extractor assembly on the end top of the chimney pipe in which it is applied, with the particularity that the clamping of the drive shaft (5) on the cross support (6) is made using a lower nut (8), while above the shaft (5) emerges above the cover upper (2) and mounted on it the corresponding bearing (9) of turn, arranged on a support (10) complemented with a base (11) conveniently fixed on the upper surface of the cover (2), said axis of rotation (5) being supported at a point intermediate through a medium support (12) that emerges from the support in cross (6) and projects upwards to an intermediate height of shaft (5), providing a means that prevents vibrations in the extractor operation.

Finally say that said extractor is complements superiorly with an aerodynamic cover (13) that covers not only the rotation bearing (9) but the support (10) and its base (11), as can be clearly seen in Figure 2, thus protecting said bearing (9) against the gas or stale air that the extractor.

Claims (4)

1. Wind extractor, which being planned to be installed both in industrial buildings and in single-family homes, neighborhood communities, shopping centers and any place or space that needs to be ventilated, and even to evacuate fumes in case of fire, is characterized by it is constituted from a plurality of vertical vanes arranged between a top discoidal cap and a lower crown, with the corresponding coupling neck to the neck of the chimney to which it is applied, on which neck a cross support is internally fixed for bearing the corresponding axis of rotation of the extractor inferiorly, said axis emerging through the upper cover, on which the corresponding bearing is placed on a support and a support base fixed to the upper surface of said cover. 2. Wind extractor, according to claim 1, characterized in that each of the vanes has upper and lower lugs for fixing on corresponding holes established for this purpose both in the upper cover and in the lower crown. 3. Wind extractor, according to previous claims, characterized in that the cross support for the lower part of the shaft is complemented with a second intermediate support that is in solidarity with the lower support itself and emerges upwards to constitute a point of easy intermediate support for the axis. 4.
