Arc curved surface blade and impeller

Abstract

The invention provides a 1 / 4 circular arc curved surface impeller capable of changing the fluid direction by 90 degrees. The rotating power can be converted into 90 degrees, and then fluid is thrown out to provide advancing power; and the fluid entering forwards can be thrown out laterally so as to provide rotating power. And the forward power and the rotating power are efficiently converted.

Description

Technical Field

[0001] The invention relates to circular arc curved surface blades and impellers, including circular arc curved surface impellers providing driving force and circular arc curved surface impellers collecting kinetic energy. Background Art

[0002] The existing impeller cannot change the direction of the fluid by 90 degrees.

[0003] The technical solution is: The invention of a 1 / 4 arc impeller that can change the direction of the fluid by 90 degrees. It can convert the rotating power by 90 degrees and then throw out the fluid to provide forward power; it can also turn the fluid entering forward into a sideways direction to provide rotating power.

[0004] Forward power and rotational power are now efficiently converted. Summary of the invention

[0005] After the fluid passes through the 1 / 4 arc blade, its direction changes by 90 degrees, from left and right to front and back, from rotating around the wheel to being thrown backwards, and from entering forwards to being thrown sideways.

[0006] The angle changes of two adjacent points on the 1 / 4 arc surface are all zero-degree transitions, which results in small energy loss and high efficiency after turning.

[0007] The beneficial effects of the present invention are: The rotational force and the forward force are efficiently exchanged.

[0008] Efficiently convert the power of the impeller's rotation into forward momentum; convert the forward momentum of the fluid flowing into the impeller into the power to drive the impeller to rotate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] As shown in the attached picture.

[0025] The 1 / 4 arc surface drives the impeller which can change the direction of the fluid by 90 degrees. According to the application scenario, determine the inner and outer diameters of the impeller sleeve, the height of the impeller, and the number of circles; install the blades with the inner wall being the 1 / 4 arc surface; distribute them evenly; make them opaque when viewed from the front; add circles; and complete the installation of each circle of blades in turn.

[0026] A one-time molding process or other processes may also be used.

[0027] The 1 / 4 arc surface kinetic energy collection impeller can change the direction of the fluid by 90 degrees. According to the needs of the application scenario, determine the inner and outer diameters of the impeller sleeve, the height of the impeller, and the number of circles; install the blades with the inner wall of the 1 / 4 arc surface on the left or right side; distribute them evenly; try to minimize the overlap between them; add circles; and complete the installation of each circle of blades in turn.

[0028] A one-time molding process or other processes may also be used.

[0029] The inner wall of the blade is a 1 / 4 arc curved surface. When the number of blades in a circle is the same, the overlapping area is large when installed in the center; the overlapping area is small when installed on the left or right side.

[0030] The less the back of the kinetic energy collection impeller is blocked, the higher the kinetic energy collection efficiency is. The best effect is when there is no overlap.

[0031] The blades overlap, which makes it difficult to process with a one-time molding process, especially casting. Solution: Add a fan-shaped extension to just cover the front view of the light-transmitting part of a circle of 1 / 4 arc curved blades distributed in a non-overlapping circular array.

[0032] The 1 / 4 arc curved blade with fan-shaped extension is characterized in that the fan-shaped extension just blocks the front light-transmitting portion of a circle of 1 / 4 arc curved blades uniformly distributed in a non-overlapping circular array.

[0033] The 1 / 4 arc curved impeller with fan-shaped extension is characterized in that: the impeller has one or more circles of blades; each circle of the circular array is evenly distributed with multiple 1 / 4 arc curved blades with fan-shaped extension; the blades just do not overlap each other; the fan-shaped extension just blocks the front view light-transmitting part of the 1 / 4 arc curved blade.

[0034] The 1 / 4 arc impeller with fan-shaped extension is just opaque when viewed from the front.

[0035] Those skilled in the art can understand that the modules or processes of the embodiments are not necessarily necessary to implement the present invention.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
