    [0002] High efficiency separating nozzle
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The purpose of the present invention application is to register a separating nozzle that incorporates significant advantages over those used up to now, particularly convenient for refrigeration and / or lubrication processes during the production of continuous longitudinally shaped metal products, such as wires, rods or bars.
    [0007] More specifically, the invention proposes a nozzle with radial channels which, due to its particular geometry, manages to slow down the circulation of the refrigerant and / or lubricant that accompanies the metal product produced, thus preventing leakage and excessive flow of said fluid.
    [0008]
    [0009] BACKGROUND OF THE INVENTION
    [0010]
    [0011] Cooling and / or lubrication systems for continuous longitudinal metal processing are known. The process requires the use of a fluid at a certain pressure to cool, wax or lubricate the metal product, providing the conditions suitable for the process.
    [0012]
    [0013] One of the main problems in current systems is the containment of the cooling / lubricating fluid. Due to the nature of the process, it is difficult to ensure that the pressurized fluid remains within the limits of the system. Any loss of fluid becomes a financial loss and an additional maintenance expense, as it can affect the operation of other components in the production line and create demand for additional repairs of other mechanical or electrical equipment. In addition, it can become a potential safety, environmental and operational hazard, or a limiting factor for measuring the efficiency of the production process.
    [0014]
    [0015] At the same time, higher speeds and higher production volumes in the facilities increase the cooling / lubrication requirements, therefore, increase the chances of loss and lack of control.
    [0016] The current devices to reduce the drag of the fluid by the metallic product and its subsequent spillage consist of nozzles located at the entrance of the nozzles where the product passes, which inject water or compressed air, or in nozzles with holes to leave water falls into a container, but given the current operating speeds in modern metal processing plants, these devices are inefficient. Therefore, there is still a need for a device capable of solving the existing problem.
    [0017]
    [0018] DESCRIPTION OF THE INVENTION
    [0019]
    [0020] The present high efficiency separating nozzle is configured as a novelty within the field of application that resolves the aforementioned setbacks. It has been developed in order to provide a way to prevent leaks and excessive flow of refrigerant and / or lubricant used during the production of continuous longitudinally shaped metal products, especially at current and future process speeds.
    [0021]
    [0022] The object nozzle consists of at least one body with a through hole, configured to link with the through hole of another nozzle, guide or nozzle, being able to be designed of different sizes to adapt to the different metal products of the process, and said hole may have a conical entry In turn, the nozzle comprises a fluidic connection from the perimeter zone to the entrance of the hole, formed by several internal sections in the form of channels that cross the nozzle radially. These channels can reach the conical wall of the entrance if available. Each of said radial channels can have a different radial inclination, or even the channel itself can have several inclination sections, which can be found at an angle between 5 ° and 90 ° with respect to the axis of the hole.
    [0023]
    [0024] For the fluidic connection of the channels with the outside, the nozzle may comprise one or several mouths or perimetral grooves located on its longitudinal surfaces or, in case the nozzle has at least one mouth, a connection channel to said mouth .
    [0025]
    [0026] Preferably, the nozzle can be divided into a series of parts that share said through hole, removable and replaceable together. The internal separation walls between the pieces can have a conical shape, at the same time that each separation can be defined by a different angle of conicity, which can be said angle between 5 ° and 90 °. The internal walls include gaps or spaces that form the aforementioned radial channels. In this way, the user can configure different sets of nozzles with channels of different volumes and exit angles.
    [0027]
    [0028] In one possible embodiment, the series of pieces can comprise a piece that houses one or more pieces of the nozzle inside it, and in another possible embodiment it can consist of series-only parts that can be joined laterally only, without a part that houses them outside . Both in one and another embodiment, the nozzle can comprise at least two pieces that are symmetrical with respect to one of the planes coinciding with the axis of the hole, so that the user can access and inspect the surface of the hole without difficulty. In the same way, there can be different sets of pieces that have different exterior geometries to adapt to the connection to other nozzles, guides or nozzles of different dimensions and shapes. To join the different types of existing nozzles, nozzle sets are also contemplated with the corresponding suitable anchoring means.
    [0029] Due to the fact that the geometry of the hole and the channels between the pieces is adjustable and can vary between piece and piece, the user can define the appropriate configuration according to the different parameters of the cooling / lubrication process, such as the type of fluid, metal product size, process speed, etc.
    [0030]
    [0031] In its condition of use, the nozzle is located in the trajectory of the metal product, either at the entrance or at the exit of the nozzle, so that the product passes through its through hole. The orientation of the nozzle depends on the direction of the flow of the coolant / lubricant, so that the inlet of the nozzle orifice is always facing said flow, regardless of the direction of advance of the metal product.
    [0032] For the use of the nozzle there are two possible methodologies. In the first methodology, the nozzle is fed through the perimeter mouth by a pressurized fluid, be it liquid or gas. Thanks to the plurality of radial channels that pass through the nozzle, the fluid reaches the hole entrance area. After the appropriate choice by the user of the number of channels and the inclination of each of them, the pressurized fluid emerges partially facing the coolant / lubricant fluid in an optimal way, generating a countercurrent flow at the inlet of the nozzle that prevents that the cooling / lubricating fluid continues its advance through the nozzle.
    [0033] In the second methodology, the nozzle is not fed by a fluid. In this case, the same refrigerant / lubricant fluid that arrives around the metal product enters through at least one of the radial sections and, depending on the geometric arrangement of the channels, emerges towards the perimeter mouth and / or towards the entrance itself of the hole through the rest of the channels. In this way, the cooling / lubricating fluid can be collected through the perimeter mouth and / or it can generate a countercurrent flow that slows it down at the entrance of the hole.
    [0034]
    [0035] Therefore, when the high efficiency separating nozzle is fed with a fluid through the perimeter groove, the operation produces a countercurrent effect against the cooling / lubricating fluid. When the high efficiency extraction nozzle is not fed with any fluid, it promotes the recirculation of the cooling / lubricating fluid itself, creating vacuum volumes and countercurrent flows that also stop the continuous flow of said fluid through the nozzle. However, in some specific cases it is acceptable to allow a reduced amount of fluid to pass through the nozzle and create a fog effect, suitable for specific cooling / lubrication processes.
    [0036]
    [0037] Finally, in any of the two previous embodiments, the fluid retained at the inlet of the nozzle can be easily collected in a container, without generating waste and whatever the parameters of the metal processing.

    [0045] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0046]
    [0047] In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    [0048]
    [0049] As can be seen in Fig. 1, a possible embodiment of the present nozzle is divided into a set of three pieces (11, 12, 13), placed in series and attached to a nozzle (2), whose through hole (20) is linked to the through hole (10) of the nozzle, in this case with a conical shaped inlet.
    [0050]
    [0051] In this embodiment, the internal contact walls (14, 15, 16, 17) between the pieces themselves (11, 12, 13) have an inclined section with respect to the axis (4) of the hole (10), with a conicity angle (a) of 15 °. The walls comprise gaps such that radial channels (18, 19) are formed between them, which appear, on the one hand, at the entrance of the through hole (10) and, on the other hand, contact a mouth (21) located in one of the longitudinal faces of the nozzle (2) by a perimeter channel (3) which, in this case, share the internal parts (12, 13) with the nozzle (2).
    [0052]
    [0053] In this embodiment, as can be seen in Fig. 1, the means for anchoring the nozzle (1) to the nozzle (2) are formed by holes (4) in the corners of the front face for threading screws (not shown in the figure).
    [0054]
    [0055] The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of this nozzle, may be conveniently replaced by others that are technically equivalent and do not depart from the essentiality of the invention or the defined scope by the claims included below.
