The invention specifically involves a spiral within a tank that provides a controlled rotational orientation to the fluid. creating a more consistent flow pattern, reducing low circulation areas, limiting air entrainment from the surface and associated foaming, and This helps to reduce the high shear effect that may occur on the mixed product.10 It relates to a mixing nozzle of the helical turbine type with a polygonal cross-section. STATE OF THE ART Previous Technique Marine-type propellers, angled-blade turbines, and dispersion turbines are used in current technology. Discs, Rushton turbines and similar mixing elements generally mix the fluid axially. or moves in the radial direction. In these systems, the fluid is mostly pushed by the outer surfaces of the mixing element. or is being dragged. The fluid is drawn into the mixing element to a defined state. limited guidance along the channel and controlled rotational orientation of the flow can remain at this level.20 Specifically, the mixing speed, the position of the mixing nozzle, and the surface movement generated. If not selected according to the process, vortices may form on the tank surface and the ambient air may circulate. Air can be drawn into the fluid, leading to foaming. Entrainment and foaming; the formation of air bubbles within the product, volumetric this can affect measurements, damage the physical structure of some products, and impact the process. This can make it more difficult to control. The following technical problems may also arise in existing systems: - extended mixing time, - increased energy consumption, - formation of low circulation areas,30 - the occurrence of non-homogeneous flow areas, - Air entrainment and foaming due to uncontrolled surface movement, - Adverse effects on the delicate product structure due to high local velocity or shearing impact. Page 1 THE PURPOSE OF THE INVENTION The aim of this invention is to move away from conventional mixing systems that merely push or transport the fluid. In contrast, it takes the fluid into the mixing element and follows defined flow paths. directing, imparting controlled rotational orientation to the flow, and having a spiral character within the tank. a mixer tip5 aimed at contributing to the creation of a circulation system It is about developing. Another purpose of the invention is to prevent the fluid from swirling uncontrollably inside the tank and on the surface. Instead of creating a vortex, it is passed through the mixing blades in a controlled manner. This helps to reduce air entrainment from the surface and the resulting foaming. to provide.10 The invention also involves the formation of a polygonal cross-sectional geometry as a result of helical twisting. internal guide surfaces and internal structure of the mixer vane module (10) Thanks to the coordinated operation of the guiding wings (7), the following technical effects are achieved: It aims to contribute to its improvement: - controlled rotational direction of the fluid,15 - redirecting the flow into a rotational flow with axial and circumferential components, - the stream splitting into multiple sub-stream paths, - Creating a three-dimensional circulation movement inside the tank.

In preferred applications, the carrier mixing vane (3) The number can be selected between three and four.10 Each carrier mixer vane (3) is connected to the central hub (2) by a vane profile connecting arm (8) It is connected via and has an internal flow-oriented polygonal cross-section in the free end region. It carries the mixing vane module (10). The mixing vane module (10) accepts the fluid. an inlet port (4) through which the fluid is discharged, an outlet port (5) through which the fluid is discharged, the ports in question flow channels (6) extending between them and the internal router located in the internal structure of the module15 It includes wings (7). Flow channels (6) are polygonal cross-section channels that extend between the inlet (4) and the outlet (5). The polygon in question is formed by the corresponding edge and vertex arrangements of geometry. Section; from pentagonal, hexagonal, octagonal or multi-sided polygonal geometries It can be created. The inlet port (4) and the outlet port (5) have the same number of sides. It can be composed of polygonal geometries. In certain applications, the cross-sectional area of the inlet port (4) is greater than the cross-sectional area of the outlet port (5). It can be designed on a large scale. However, the flow-directing effect of the invention is only verbal. The issue is not dependent on changes in cross-sectional area. Flow channels (6) in the mixing vane module (10) from the inlet port (4) to the outlet port (5)25 It forms a geometry that is twisted in a straight helical manner. Within the scope of this specification, the helical angle of torsion is defined as a polygonal cross-section of the inlet opening (4). The angular position of the corner, edge or junction line and the corresponding outlet opening (5) angular around the longitudinal axis of the flow channel (6) of the corner, edge or junction line It expresses the difference in position. The helical torsion angle is between 30° and 90°. It can be selected. Polygonal wall surfaces that confine the flow channels (6) during helical torsion of the module (10) extends helically around its longitudinal axis; the corresponding corner of the polygonal section and its edges follow helical lines between the inlet (4) and the outlet (5). These helical wall surfaces allow the fluid to flow as it moves along the fluid flow channels (6). Page 4 a steering geometry that contributes to providing a peripheral speed component It constitutes. Two to six internal guide vanes (7) inside the mixing vane module (10) It can be found. At least two of the internal guiding wings (7) are located in the internal structure of the module (10), initial connection5 corresponding to the common intermediate region of two adjacent flow channels (6) The mixing wing extends between the inlet (4) and the outlet (5) of the regions. The modules (10) are connected diagonally at the geometric center of each other. Within the scope of this specification, the same helical torsion direction; from the inlet (4) to the outlet (5) channel walls and internal routers that limit the flow channels (6) when progressing correctly the wings (7) rotate clockwise around the longitudinal axis of the mixing wing module (10)10 or it indicates that it exhibits angular displacement in the counterclockwise direction. Internal guide vanes (7), together with flow channels (6) from inlet port (4) to outlet port (5) This contributes to the formation of multiple continuous flow paths that extend for a considerable distance. The fluid passes through the helical channel walls and inside as it moves from the inlet (4) to the outlet (5). They are directed along the flow paths formed by the guiding vanes (7) together and15 In addition to the axial component, it can also acquire a circumferential flow component. The flow directing effect targeted by the invention is only possible with polygonal cross-section flow channels (6) from the use of or only the presence of internal guide vanes (7) It does not originate from this. The effect in question is caused by the helical torsion of the polygonal cross-section. guiding surfaces and inner surfaces extending in the same helical torsional direction as these surfaces20 As a result of the coordinated operation of the guide vanes (7), the fluid is controlled It contributes to its guidance. The longitudinal axis of the mixing shaft (9) is the Y-axis of a coordinate system, the mixing end (1) The plane of rotation is considered to be the XZ plane. The origin of the coordinate system is... The center of the mixer shaft (9) is at the point where it joins the hub (2). Clockwise definition means the shaft25 This is done based on a perspective from the +Y direction on the motor connection side towards the origin. In the preferred application, the mixing tip (1) is clockwise when viewed from the +Y direction towards the origin. It rotates in the direction of the inlet ports (4) of the relevant mixing vane. It will look at the instantaneous direction of motion tangent to the trajectory of motion; the exit ports (5) are the word The subject is positioned to face the opposite direction of the tangential movement.30 In the alternative application, mixing vanes (3), inlet and outlet ports (4, 5), helical channel walls and internal guide vanes (7) are formed in mirror geometry and the mixing tip (1) It can be configured to operate counterclockwise, relative to the same viewing direction. In addition to their orientation opposite to the tangential direction of movement, the outlets (5) are directed towards the fluid. an exit direction that is radial, axial, circumferential, or any combination of these directions35 It can be positioned in a way that will generate profit. Page 5 The fluid flows along defined flow paths within the mixing vane modules (10). redirection, high surface vortices and surface air drag It can contribute to its limitation. Mixer vanes (3) are attached to the central hub (2) by means of vane profile connecting arms (8). It is connected. The wing profile connecting arm (8), mixing wing (3) and central hub (2)5 It forms a seamless mechanical connection between them and wing-like structures that come into contact with the fluid. It includes orientation surfaces. Wing-like guiding surfaces of wing profile connecting arms (8), hub The surrounding fluid is directed towards the inlet openings (4) of the relevant mixing vane modules (10). It is oriented in such a way as to... This definition is based on a specific airfoil thickness ratio, curvature10 It is not limited by radius or angle of attack. Wing profile connecting arms (8), with equal angular spacing to match the number of mixer blades. It can be placed around the central hub (2) and each connecting arm with the corresponding inlet port. (4) The flow can be formed in a direction that will match the orientation. Within the scope of this specification, the outer diameter of the mixing tip (1) is 15 during the rotation of the mixing tip. The outermost points of the mixer vane modules (10) are formed around the shaft axis It represents the diameter of the sweep circle. The module length is the distance between the inlet port (4) and the outlet port. (5) represents the longitudinal length of the mixing vane module (10) extending between them. The mixing blades (3) are balanced relative to each other around the central hub (2) and circumferentially. They are positioned in a distributed manner. The hub of the mixing blades (3)20 The angular arrangement of the blades around the surrounding area depends on the number of mixing blades used. This can be determined in a way that will provide a regular environmental distribution among them. This settlement thanks to the mechanical loads and flow generated during the rotation of the mixing tip (1) This helps to distribute the guiding effect evenly around the navel. The outer diameter of the mixing tip (1), the length of the mixing blades (3) and the mixing blades25 The settlement around the central hub (2) is not limited by a fixed measure or ratio. The subject is dimensional parameters; tank inner diameter, tank and liquid filling height, tank base. geometry, presence or absence of a flow breaker element inside the tank, fluid density and rheological properties, solid content, mixing tip rotation speed and formation. This can be determined by taking into account the intended circulation pattern.30 The outer diameter of the mixing tip (1), the longitudinal length of the mixing vane modules (10) and the center The placement around the hub (2); the geometry of the tank in which it will be used, the rheological of the fluid Considering the characteristics, mixing volume and intended circulation pattern, the laboratory, It can be adapted to pilot or industrial scale.

The mixing tip can be selected in a way that will contribute to the formation of the regions. Thus, the mixing tip adapting the tank and mixing process where the effective flow area will be used and low The aim is to reduce circulation zones. These dimensional parameters are either independent of each other or related to each other.5 It can be modified, and these modifications affect the polygonal cross-section helical orientation of the invention. Basic flow based on the combined operation of the surfaces and the internal guide vanes (7) It does not change the guiding principle. In the preferred production method, each carrier mixer blade (3) has a blade profile attached to it. connecting arm (8), internal flow-directed polygonal cross-section mixer vane module (10) and10 The circumferential segment of the central hub (2) corresponding to the wing in question is cast in one piece. It is created as a sub-unit. Preferably three to four one-piece cast sub-units. When brought together circumferentially, the central segments complement each other, forming a circular shape. It forms the cross-sectional central hub (2). Passing the mixing shaft (9) through the center of the assembled hub segments15 a suitable common mounting hole is created or after the hub segments are joined The mounting hole in question is machined to the desired shaft diameter. Alternatively, The mixing end can be fixed to the mixing shaft (9) by welding. The lower units are cast. While it is preferable to create one that does not alter the fundamental flow geometry of the invention, Other suitable manufacturing methods can also be used.20 Within this segmented structure, the term 'one-piece' means that the entire mixing nozzle is a single piece. not that; each carrier mixer blade (3), the corresponding connecting arm (8), the corresponding mixer The wing module (10) and the corresponding hub segment can be connected to each other with additional or detachable connections.
