Field of the Invention

The present invention relates to a pump with a toroidal structure developed for pumping liquids and gases.

The invention particularly relates to a pump that operates by accelerating and rotating the fluid around the axis of the pipe by two blades, one rotor blade and the other stator blade inside a torus-shaped pipe. Although said pump contains a rotor and a stator, it relates to its being more than two-stage pump with the rotating shape of its housing.

State of the Art

Fans or pumps, with its general definition, are mechanical devices used to transfer gases or liquids (fluids). It moves the fluid from low pressure to high pressure. They operate by using the principle of pushing the material with the physical lifting or compression force of mechanical forces by Archimedes in 3 rd century BC.

The most common pumps that operate by accelerating the air are the axial, centrifugal and regenerative pumps. Furthermore, multistage pumps connected in series so as to increase the pressure are disclosed. Among the pumps here, there are sections called stator with fixed blades that direct the flow of the fluid.

The fluid moves perpendicular to the direction of rotation of the blade in axial pumps. The fluid accelerates in the direction of rotation of the blade or impeller in the centrifugal pumps. Regenerative pumps have a slot in the form of a toroidal slice. The blade gives the fluid a bidirectional movement perpendicular and parallel to the direction of rotation of the blade. The fluid is pumped by flows in the direction of rotation of the blade. This type of pump is sold with a silencer, since noise is created between the inlet and outlet.

In the patent application numbered TR2019/18506, which is one of the applications encountered as a result of the researches on the state of the art, a centrifugal pump comprising a pump chamber, a wear plate and a rotor blade is disclosed. The wear plate has a suction inlet. The pump chamber comprises a high pressure zone around the blade within the pump chamber. The front face of the blade has a section located adjacent to the wear plate so as to form a circulation zone in fluid communication with the high pressure zone. Another section of the blade front face forms a small operating space between it and a section of the wear plate. The relevant operating space is placed between the circulation zone and the suction inlet. The wear plate comprises a plurality of diverter blades projecting into the circulation zone. A part of the front face of the blade comprises a plurality of pumping blades within the circulation region. The diverter blades operate in conjunction with the pumping blades so as to throw abrasive particles and prevent them from accumulating in the operating space and eroding the same.

In the utility model numbered TR2013/02217, a centrifugal pump comprising a spiral casing, a fan positioned in said spiral casing, a water receiving element mounted on the fan, a water outlet element from which water is discharged so as to ensure transferring the water supplied from places such as lake, stream, water canal etc. to the irrigation area by an engine is disclosed. Said centrifugal pump comprises a shaft connected to the motor at one end and placed at the hub of the fan from the other end so as to ensure that the drive of the motor is transferred directly to the fan and at least one seal on the shaft where the shaft contacts the fan so as to prevent the centrifugal pump from leaking water.

Detailed Description of the Invention

In this detailed description, the preferred embodiments of the inventive type of toroidal pump (P) is described only for clarifying the subject matter in a manner such that no limiting effect is created.

The subject of the invention is a toroidal (torus-shaped) pump (P) that pumps liquid or gaseous fluids, characterized in that, it comprises a body (G) that contains a housing (Y) with torus-shape where the parts of the instrument are placed. There are central inlet channel (50) and side inlet opening (70), outlet opening (20) and stator blades (32) extending into the housing (Y) on the body (G). A rotating rotor (C) is positioned inside the housing (Y).

The inventive pump (P) pumps the fluid in the housing (Y) by rotating the same around the axis of the housing. Rotor and stator blades are tools for this purpose. Accordingly, blade and stator blade systems of conventional instruments can be applied for this pump. The property that makes this device different is that there is no existing pump that pumps the pressure on the surface of the housing with the centrifugal force of the loop in the torus structure and the fluid velocity on the surface of the housing.

The rotor blades (31) of the inventive pump (P) are configured so as to rotate the fluid around the axis of the tubular structure of the housing (Y) (second diameter of the torus). Thus, the rotor (C) pushes the fluid in the direction perpendicular to or close to its rotation direction. Stator blades reflect the fluid coming from the blade back to the same blades of the rotor.

The figures show examples of blades of construction and function similar to those in conventional centrifugal or axial turbines. In this direction, the rotor blades can be designed in different manners, and blades (31 , 32) in axially effective spiral structure are configured in Figure 10.

The stator blades (32) connected to the body are configured such that they direct the fluid flow in the housing perpendicular to the rotor (C) or direct the rotor blades (31) towards the incoming direction. The blades of the pump (P) are designed with various blades similar to those in conventional pumps, turbines or similar devices.

The inventive pump (P) pumps with the speed and centrifugal force of the fluid rotating in the housing (Y) with the effect of rotor blades (31) and stator blades (32). For this purpose, there are blade channels (10) extending from root to tip inside the blades (31 , 32) that will transfer the fluid to the center of the housing (Y). The blade channels (10) connect the center of the housing (Y) to the central inlet channel (50). The blade channels (10) can be made within the stator blades (32) or the rotor blades (31). If it is done on the rotor blades, then the central inlet channel is moved to the center of the rotor. Thus, the fluid comes from the external environment to the blades (31 , 32) with the central inlet channel (50), and to the center of the housing (Y) with the blade channels (10). Since the rotor blades (31) reach the center of the housing (Y), it is also possible to configure channels in them. The secondary inlet to the housing (Y) is provided by the side inlet (70) on the side wall of the housing (Y). The side inlet (70) draws the fluid in the housing (Y) with its velocity. For this process, the side inlet (70) is configured as an opening in the direction of the flow of fluid from the body (G) to the housing (Y). The side inlet (70) can be configured to be opened from any part of the body (G) to the housing (Y). The important thing is that the inlet (70) enters in the direction of flow inside the housing (Y).

The pump (P) can be configured to operate at different pressures and types by opening and closing any of the side inlet (70) and central inlets (50). Alternatively, the pump (P) can be configured as only side inlet (70) or only central inlet (50) models as required. The fluid that enters the pump (P) from the side inlet (70) drags by the flow therein. In this case, the blades (31 , 32) interact only with the centrifuged clean fluid and are not damaged by the substances within the fluid. When the instrument is used so as to mix and pump two different substances, it is appropriate to direct the fluid that will damage the blades to the side inlet.

The property of the outlet opening (20) in the inventive pump (P) is that it opens from the housing (Y) in the direction of the flow of the fluid in the housing (Y). In this way, the fluid is evacuated from the outlet opening (20) with its current velocity. The direction of the outlet opening (20) supports the fluid outlet with the velocity energy of the flow inside.

In the inventive pump (P), the fluid flow is perpendicular to the rotation of the rotor (C). It differs from centrifugal pumps in terms of this loop direction and is similar to regenerative pumps. However, the housing of regenerative pumps is like a torus slice and the rotor carries the fluid from one end to the other. Noise occurs between the inlet and outlet of these pumps. In the inventive pump (P), it does not move with the rotor (C) with the stator baldes (32) therein, but pumping is carried out with the centrifugal force inside the housing (Y) and the fluid velocity on the wall of the housing (Y). Thus, noiseless operation is ensured. Moreover, while the torus diameter of the regenerative pumps has to be limited, there is no such limit in the inventive pump (P).

The inventive pump (P) is a kind of multi-stage pump with stator blades (32), it performs the multi-stage with only one rotor (C) and a stator blade (32) system.

In the inventive pump (P), the diameter of the toroidal body (G) and the rotor (C) can be adjusted at the required level so as to fulfill the needs. At the same time, the blades (31 , 32) can be configured in various shapes such as circular cross-sections or spirals to complement each other. Furthermore, the blades (31 , 32) can be positioned perpendicularly or at various angles according to the requirement. One of the preferred embodiments of the inventive toroidal pump (P) is shown in detail from different angles in figure 1 , figure 2 and figure 3. In this preferred embodiment of the invention, the pump (P) has side (70) and central inlets (50) and operates in 3 different manners. In this configuration, the rotor blades (31) have a centrifugal structure with forward inclination. A body (G) essentially consists of the following; a central inlet channel (50) for providing fluid inlet, a side inlet (70) which also provides the inlet of the fluid, at least one blade channel (10) for conveying the fluid into the pump, at least one outlet opening (20) for providing the outlet of the fluid in the body (G), rotor blades (31) and stator blades (32).

The second preferred embodiment of the inventive pump (P) is given in detail in figure 4, figure 5 and figure 6. This structure only contains a central inlet (50) by cancelling the side inlet (70) of the toroidal pump (P) that is configured in figure 1. In the pump (P), the fluid reaches the center of the housing (Y) only through the central inlet channel (50) and the blade channel (10). The fluid is dragged to the outlet opening (20) with the centrifugal force and velocity created by the loop in the housing (Y).

In Figure 7, the third preferred embodiment of the inventive pump (P) is given. In said preferred third embodiment, the pump (P) generally comprises a body (G), a rotor (C) configured engaged to the body (G), a side inlet (70), an outlet opening (20), and blades (31 , 32). In a preferred embodiment, the blades (31 , 32) are positioned at an angle to each other. The fluid inlet to the pump (P) is carried out from the side inlet (70). The outlet opening (70) can be placed on the body between the body and the rotor or on the rotor. It uses the contribution of the flow velocity to the pumping with its outward opening structure in the flow direction in that housing. The fluid outlet from the pump (P) is realized through the outlet opening (20). The outlet opening (20) can be on the body (G) between the body and the rotor (C) or on the rotor. The side inlet (70) and the outlet opening (20) provide a benefit eliminating friction when they are between rotor and the body.

According to Figures 8 and 9, the fourth preferred embodiment of the inventive pump (P) is given. It has a similar embodiment with Figure 1 , but the difference from the pump (P) provided in Figure 1 is that the blades (31 , 32) are in the form of flat centrifugal pump blades.

In the fifth preferred embodiment of the inventive pump (P) in Figures 10 and 11 , impeller blades (31) are helical like screw pitch, it works with the operating principle of axial pumps and it shows that the inventive toroidal pump (P) can be made with different blade (31 , 32) structures. The central and side inlets (50, 70) are configured in the pump (P). Furthermore, side inlet (70) and outlet opening (20) in this pump (P) are located in different parts of the body (G), showing that flexible placement is ensured. In figures 12 and 13, in the sixth preferred embodiment of the inventive pump, the blades (31 , 32) are configured as in axial fans. In this preferred embodiment, only the side inlet (20) is used. Fluid movements are indicated by hollow arrows.
