TECHNICAL FIELD

The present invention relates to at least one ejector comprising at least one flow path for transferring a high flow rate fluid, that is diffused while being carried, to a diffusor, at least one first suctioning way and at least one second suctioning way for mixing by carrying lower flow rate fluid to said flow path.

PRIOR ART

Ejector is an equipment that enables energy transfer between a high pressure fluid and a low pressure fluid and that pressurizes low pressure fluid by means of this. The fluid which exists at high pressure is named as the primary fluid, and the fluid which exists at low pressure is named as the secondary fluid. An ejector, which does not include any mechanical part, essentially consists of four main parts. These parts are bullet nozzle, suctioning chamber, mixture chamber and diffusor.

Ejectors are used in processes like vacuuming, circulation, separation in various branches of industry. Ejectors, which do not have movable parts and which have a simple geometry and which operate without noise and which have long lifetime, basically can be defined as apparatus which transform the pressure energy of the pressured primary fluid into kinetic energy and which form vacuum effect and which suction the secondary fluid and which mix the suctioned secondary fluid and primary fluid and which transform the kinetic energy of these mixed fluids into pressure energy again.

The application with no CN201820822030U known in the literature relates to a two-channel ejector with adjustable suctioning. Accordingly, the solution comprises a double suctioning channel which has output to a suctioning chamber where the first fluid forms suctioning force, and a regulation valve positioned on the suctioning channel for controlling the flow of the secondary fluid.

The application with no US201213692505 known in the literature relates to an ejector for controlling a flow or flow rate of the lateral flow gas in a correct manner. Accordingly, the invention comprises a needle valve for controlling fluid passage and placed coaxially into the nozzle where the suctioning fluid will pass, and comprises suctioning openings provided in pluralities of numbers for auxiliary fluid output.

The application with no W02002N000353 known in the literature relates to an ejector comprising pluralities of suctioning channels. Accordingly, suctioning channels are positioned symmetrically around the ejector and such that there is equal angle in between with the flow direction. The solution comprises pluralities of suction channels.

The systems known in the literature do not have high vacuuming potential. Therefore, the inner geometry and the suctioning lines known in the present art do not enable this. This leads to inefficient operation of the systems which exist in the present art.

As a result, because of the abovementioned problems, an improvement is required in the related technical field.

BRIEF DESCRIPTION OF THE INVENTION

An object of the present invention is to provide an ejector for use as air raiser.

Another object of the present invention is to provide an air raiser ejector with improved vacuum effect.

Another object of the present invention is to provide an air raiser ejector with adjustable vacuum amount.

In order to realize the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention is at least one ejector comprising at least one flow path for transferring a high flow rate fluid, that is diffused while being carried, to a diffusor, at least one first suctioning way and at least one second suctioning way for mixing by carrying lower flow rate fluid to said flow path.

In another possible embodiment of the present invention, the valve is positioned in the vicinity of both the first suctioning way and the second suctioning way and the diffusor. Thus, the desired mixture proportion is adjusted in the ejector as desired, and the fluid speed can be controlled accordingly.

In another possible embodiment of the present invention, the ejector is an air raiser. Thus, the desired mixture adjustment can be realized during carrying of air.

In another possible embodiment of the present invention, at least one narrowing form and at least one widening form are provided between the diffusor and the first suctioning way and the second suctioning way on the flow path.

BRIEF DESCRIPTION OF THE FIGURES

In Figure 1 , a representative frontal cross-sectional view of the subject matter ejector is given. DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In Figure 1 , a representative frontal cross-sectional view of the subject matter ejector (1) is given. Accordingly, the subject matter ejector (1) enables actuation of the low pressure fluid depending on energy transfer between the high pressure fluid and the low pressure fluid. Ejectors (1) are used in processes like vacuuming, circulation, separation in various branches of industry. An ejector is frequently used in the present art since there is no movable part, it has a simple geometry, it operates in a silent manner and it has long lifetime. In the invention, said ejector (1) is essentially an air raiser ejector (1 ). The pressure raiser ejector (1) provides increasing of air pressure up to the desired force values in local applications where the force is insufficient and where the air pressure is low in pneumatic systems. Pressure raisers can increase air pressure up to 2 and 4 times.

The subject matter ejector (1) has at least one channel (10) structure. There is a flow path (20) at the inner part of said channel (10). In said flow path (20), it is enabled to pass the desired fluid. The flow path (20) is associated with at least one first suctioning way (21 ) and at least one second suctioning way (22) from one side and is associated with at least one diffusor (26) from the other side.

High flow rate and pressured fluid is carried at said flow path (20) which exists at the ejector (1 ). Said first suctioning way (21 ) and said second suctioning way (22) are flow paths (20) which enable carrying of low pressure and low amount fluid desired to be mixed into the high flow rate fluid carried through the flow path (20). In a possible embodiment of the present invention, the same type of fluid can be mixed to the high flow rate fluid through the first suctioning way (21) and the second suctioning way (22). In alternative embodiments, low flow rate fluid with different types can be mixed in the high flow rate fluid in the ejector (1).

The first suctioning way (21 ) and the second suctioning way (22) and the flow path (20) are positioned orthogonally to each other on the flow path (20) of the ejector (1). There is at least one mixing region (23) at the part where the first suctioning way (21 ) and the second suctioning way (22) are connected to the flow path (20). At said mixing region (23), the carried high and low flow rate fluids are mixed with each other. At said diffusor (26) part, the fluid mixture carried with high pressure and flow rate is enabled to be diffused. In order to enable this, there can be at least one nozzle (not shown in the figures) on the ejector (1 ). Said nozzle can enable automatic adjustment of the amount of fluid mixed to the flow path (20). The nozzle can exist in the mixing region (23).

At the flow path (20), there is at least one narrowing form (24) and at least one widening form (25) between the first suctioning way (21 ) and the second suctioning way (22) and the diffusor (26). Said narrowing form (24) provides increasing of the flow rate by narrowing the flow diameter of the fluid carried in the flow path (20). In the widening form (25), the flow diameter of the fluid carried in the flow path (20) is widened and the flow rate thereof is decreased and diffused at a wide volume. For enabling this, it is characterized in that the inner diameter of the flow path (20) narrows as the narrowing form (24) approaches the widening form (25). In a similar manner, it is characterized in that the diameter of the flow path (20) widens as the widening form (25) moves away from the narrowing form (24).

There is at least one valve (30) on the ejector (1 ). Said valve (30) enables delimiting of the amount of fluid carried through the flow path (20). The valve (30) is an apparatus which provides adjusting, stopping, starting the stopped flow or increasing the flow rate of the fluid for the flow of the fluid carried from one place to another place in the flow path (20). Thanks to the valve (30), the needed fluid carrying amount can be adjusted. For providing this, the valve (30) can essentially be a first valve (31 ). Said first valve (31) is essentially positioned on the first suctioning way (21 ). Said first valve (31 ) enables delimiting, stopping or adjusting of the amount of fluid carried through the first suctioning way (21 ). In a possible embodiment of the present invention, the valve (30) can be a second valve (32). Said second valve (32) is essentially positioned on the second suctioning way (22). Said second valve (32) enables delimiting, stopping or adjusting of the amount of fluid carried from the second suctioning way (22). In another possible embodiment of the present invention, the valve (30) can be a third valve (33). Said third valve (33) is essentially positioned on the flow path (20). Said third valve (33) enables delimiting, stopping or adjusting of the amount of pressured and high flow rate fluid carried in the flow path (20). The third valve (33) is preferably positioned in the middle of the narrowing form (24) and the widening form (25). In the invention, said valves (30) can be manually controlled, and in a possible embodiment of the invention, said valves (30) can be automatically controlled. By means of this, the desired mixture proportion can be realized.

In a possible embodiment of the present invention, both the first valve (31 ) and the second valve (32) and at the same time, the third valve (33) exist together. By means of this, the mixture proportion expected to exist in the carried fluid can be adjusted in predetermined manner. Additionally, thanks to the narrowing form (24) and the widening form (25), the ejector (1) efficiency and capacity can be adjusted.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
