Description
- The present invention belongs to the field of dispensing liquids and/or fluids. In particular, the present invention relates to the field of dispensing atomized fluids by means of one or more nozzles or dispensing devices in general.
- Even more in particular, the present invention relates to a connecting manifold element adapted to allow the easy installation of one or more compressed air atomization nozzles or devices served (supplied) by a plurality of pipes or ducts, of which in particular one intended for water supply and more than one (for example three) intended for air supply.
- In detail, the present invention relates to a connecting manifold element of the aforesaid type adapted to be applied to said plurality of main ducts or pipes so as to intercept the fluids (in particular water and air) transiting in said main pipes and to dispense a mixture of said at least two fluids. Even more in detail, the present invention relates to an element of the aforesaid type conceived so that the application thereof to said main pipes or ducts is particularly simplified and fast, as well as so that it can be assembled in simple and fast manners and therefore at low costs.
- In the field of dispensing atomized liquids, the use of one or more dispensing nozzles of the compressed air atomization type is known.
- Said devices, commonly called *compressed air atomizers*, proved to be useful and are therefore widely used in the production of atomized jets consisting of fine drops of liquid obtained by a process in which a jet of air strikes drops of water, fractionating them into much smaller drops and projecting them at high speed outside the orifice of the nozzle or dispensing device.
- In various industrial applications, in particular in which a series of atomizers are mounted in parallel along a plurality of supply ducts, it is often necessary to interrupt the flow of the liquid to be atomized at will, and to have a further compressed air line to modify the shape of the output atomized jet.
- This is achieved through special atomizers provided with two auxiliary air inlets and with independent control, one of which activates a piston which interrupts the flow of the liquid to be atomized with a needle, while the second strikes the output atomized jet with two lateral jets of air which modify the shape thereof.
- In the above cases, each atomizer must thus have four supply lines, one for liquid (usually water) and three (with independent pressure regulation) for air (or more generally gas).
- This involves a series of possible drawbacks which can be summarized as follows. A first drawback is that the installation of, for example, six atomizers involves arranging as many as twenty-four supply ducts with an apparent negative impact on assembly and/or installation times and possible sealing problems.
- A second drawback is that, in the systems used in processes involving dust, there is inevitably a dramatic accumulation of encrustations on the several pipes present which, in the systems used in food or health processes, must be eliminated regularly and with great care and therefore require frequent stops with reduction of system productivity.
- And finally, a further problem relates to the pressure drops in the fluid supply lines for the various atomizers, depending on the position thereof along said supply lines, wherein the atomizers farthest from the air supply source risk being supplied with insufficient air pressure, especially if the air supply line is not provided with an air inlet at each of the two ends.
- To overcome the drawbacks summarized above, the following solutions have essentially been adopted.
- According to a first solution, a metal support is used, such as a tube or a profile, to which atomizers and related supply lines are fastened, wherein alternatively the whole set of atomizers and related pipes is accommodated in a tube of greater diameter, and wherein in this case it is necessary to perforate said greater diameter tube at the positions provided for the spraying orifices. With considerable and intuitive costs and complications, this latter solution only overcome the problem of the rapid cleaning of the set.
- According to a second solution, use is made of a modular construction with two types of elements side by side: actual atomizers and connecting pieces with the same outer profile, which are tightened together to form the final manifold; this second solution involves exorbitant costs due to the number of holes to be included (at least four for the supply ducts plus at least two for the tightening tie rods), and does not overcome the problem of pressure drops in the air ducts, on the contrary it somehow aggravates it.
- It is thus the main purpose of the present invention to overcome or at least minimize the drawbacks outlined above and affecting the prior art.
- In particular, it is a first object of the present invention to provide a solution which allows connecting one or more atomizers and the main pipes in a simple, safe, easy, and immediate manner. Furthermore, it is one of the objects of the present invention to provide a solution of the aforesaid type which possibly also allows the simultaneous connection of several atomizers to the main pipes.
- Finally, it is a further object of the present invention to provide a solution of the aforesaid type adapted to be used in different types of systems which can be installed in different environments, i.e., both large and medium or small size, by means of simple and/or immediate operations and which, in particular, avoids drastic structural interventions on the aforesaid structures.
- The present invention is based on a very simple concept, i.e., to use the support of a manifold, in particular consisting of a set of several tubes (for example four tubes) mutually constrained (for example welded together), to channel through sections of considerable dimensions both the liquid to be sprayed and the three air supplies required.
- As explained below, the above general concept includes a very simple mode and does not require threaded connections of any kind to mount the atomizers on the manifold quickly while ensuring the seal of the connections.
- In light of the above considerations, as well as in view of the problems and/or drawbacks encountered in the fire-fighting devices and/or systems according to the prior art, the present invention relates to a connecting manifold element according to claim 1, wherein further embodiments of the connecting manifold element according to the present invention are defined by the claims.

On the contrary, the present invention finds convenient application in all cases where it is necessary to connect at least one fluid dispensing device to a plurality of main supply pipes or ducts in a quick and reliable manner.
- According to the embodiment of the present invention depicted in
figures 1 to 4 , the self-supporting connectingmanifold 100 comprises a firsttubular element 101, a secondtubular element 102 and afluid dispensing device 103; in this regard, it should further be noted that as depicted, themanifold 100 can comprise a number of tubular elements greater than two (for example four tubular elements as depicted) and a number of dispensingdevices 103 greater than one (for example two as depicted). However, since the tubular elements and the fluid dispensing devices of the self-supportingmanifolds 100 according to the embodiments of the present invention are substantially based on the same constructive concept, for reasons of clarity and synthesis, a description will be given below of a self-supportingmanifold 100 comprising twotubular elements dispensing device 103. Thetubular elements manifold 100 is intended to be connected, in particular assuming that said two main pipes or ducts have a similar shape. It will therefore be assumed in the following, for reasons of clarity, that the self-supportingmanifold 100 is intended to be connected to two adjacent and parallel main pipes having a similar shape (in particular section) to that of the twotubular elements manifold 100 to the aforesaid two main pipes, a portion of a length corresponding to or slightly greater than that of thetubular elements tubular elements tubular elements tubular element 101 and respectively by thetubular element 102. It will further appear clear from the following description that, since both thetubular elements device 103, the connection of thetubular elements device 103 and in the dispensing of a fluid by thedevice 103 under variable forms in terms of composition, pressure, flow rate, shape of the jet or spray depending on the type ofdispensing device 103 and the fluids intercepted. - In fact, as depicted, the
device 103 comprises a dispensing terminal 104 (for example an atomizer) and aninterface element 105, mutually fastened by means ofscrews 106 extending through theinterface 105 and engage respective internally threaded blind holes (not shown) of thedispensing terminal 104. Furthermore, theinterface 105 and the dispensingterminal 104 are placed in fluid communication by achannel 108 inside theinterface 105, extending perpendicularly to the main opposite andparallel surfaces interface 105 which delimit theinterface 105 in the direction of the thickness thereof, wherein one end of thechannel 108 opens onto thesurface 1051 of theinterface 105 placed in contact with thedispensing terminal 104. Furthermore, thechannel 108 is positioned at and thus placed in communication with acavity 109 of the dispensingterminal 104, which in turn communicates with the dispensing end 110 (for example a nozzle) of the dispensingterminal 104, for example by means of a mixing and/or atomization chamber (not shown). - The
interface 105 comprises asecond channel 107 parallel to saidfirst channel 108, wherein thesecond channel 107 comprises an end which opens onto thesurface 1050 of theinterface 105 opposite thesurface 1051. Saidfirst channel 108 andsecond channel 107 are also intercepted by athird channel 111 extending perpendicularly to saidfirst channel 108 and second channel 107 (and therefore along a direction substantially parallel to thesurfaces 1050 and 1051), wherein saidthird channel 111 opens onto a transverse surface of theinterface 105 to define anopening 112 closed by aremovable screw plug 113. - Again as shown, a
tubular connection element 114 is fastened to theinterface 105 at thesecond channel 107 and partially protrudes from thesurface 1050 of theinterface 105, asealing ring 115 being positioned on thesurface 1050 of theinterface 105 to surround the protruding part of thetubular connection element 114. With the dispensingdevice 103 fastened to thetubular elements figures 2 and3 (as well as according to the methods explained below), thetubular connection element 114 is placed at and put in communication with a hole (not shown in the figures) obtained through the wall of thetubular element 101 placed in contact with theinterface 105, the dispensingterminal 104 therefore being placed in fluid communication with the interior of thetubular element 101. - What is described above is also applicable to the
tubular element 102 the interior of which is placed in fluid communication with the dispensingdevice 103 through a hole obtained in the wall thereof in contact with theinterface 105 and in turn placed in fluid communication with the dispensingterminal 104 by an annular connection element, a first, a second and a third channel as well as a cavity similar to theconnection 104, thefirst channel 108, thesecond channel 107, thethird channel 111 and thecavity 109, respectively. - Furthermore, the methods described above according to which the
