Description
Technical Field
The invention relates to the technical field of gas (liquid) pumps and gas (liquid) turbines, in particular to an impeller and a vortex device with the same.
Background
A vortex device is a gas (liquid) pump or a gas (liquid) turbine with an impeller, for example, a vortex pump is used for transmitting kinetic energy to a fluid medium (such as liquid or gas) in the movement direction of the fluid medium by rotating the impeller to apply force to the fluid medium, so as to achieve the purpose of conveying.
The vortex pump is a high-pressure vane pump and mainly consists of an impeller, a pump body and a pump cover. The impeller is of a disc structure, and the circumference of the impeller is provided with radial evenly arranged sheets. An annular flow passage is formed between the pump body and the impeller, and the suction inlet and the discharge outlet are both arranged at the outer circumference of the impeller. Wherein a partition is provided between the suction port and the discharge port, thereby isolating the suction port from the discharge port. The fluid medium in the vortex pump generates a certain centrifugal force when rotating along with the impeller, and is thrown outwardly into the annular flow channel in the housing and forced to flow back under the restriction of the flow channel shape. The path of movement of the liquid between the vanes and the annular flow passage is thus a progressive spiral for a stationary housing; and for the rotating impeller, the spiral line is a backward spiral line; the vortex pump is named for this swirling motion of the fluid medium. The fluid medium can enter between the blades a plurality of times in succession to acquire energy until finally discharged from the discharge port. The operation of the scroll pump is somewhat like a multistage centrifugal pump, but the scroll pump does not act like a centrifugal pump volute energy conversion device. The vortex pump mainly transmits energy to the liquid in a mode of continuously doing work for a plurality of times, so that higher pressure can be generated.

Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1-3, one embodiment of the impeller of the present invention includes a wheel disc body 1, an annular outer wheel 2 with a thickness smaller than that of the wheel disc body 1 is disposed around the periphery of the wheel disc body 1, a plurality of blades 3 perpendicular to the annular outer wheel 2 are disposed on two sides of the annular outer wheel 2, and the blades 3 are arranged around the annular outer wheel 2 in a scattering shape.
As shown in FIG. 2, the blade 3 is of a metal sheet structure, and the ratio of the diameter of the impeller to the thickness of the blade 3 is 100-2000:1. For example, the thickness of the vane of the conventional vortex pump impeller with the diameter of 200mm is generally designed to be 5mm, and the thickness of the vane 3 can be designed to be 0.35mm (the ratio of the diameter of the impeller to the thickness of the vane is about 500:1) according to the embodiment of the invention, so that the thickness of the vane is greatly reduced compared with that of the conventional vane.
The top of the blade 3 is formed into a top surface 32 parallel to the bottom, and two sides of the blade are respectively connected with a first arc slope surface 31 and a second arc slope surface 33 which are connected with two side edges of the top surface 32, so that the thickness of the blade is reduced compared with that of the existing blade, and the existing rectangular blade is changed into a structure with arc slope surfaces on two sides. To cope with the problem of insufficient strength of the blade after reduction, in this embodiment, an annular bracket 4 is provided in the middle of the top surface of the blade 3 on the same side, the annular bracket 4 is embedded in the blade 3, and the top surface of the annular bracket 4 is flush with the top surface 32 of the blade 3. Because the thickness of the blade 3 is reduced, the resistance is smaller, the efficiency is improved, the problem that the strength of the blade is insufficient due to the reduction of the thickness is solved by the arrangement of the annular bracket 4, and the blade can be used in a larger range.
Referring to fig. 4-7, the embodiment of the present invention further provides a vortex device with the impeller, which includes a housing 5 and the impeller disposed in the housing 5, and this embodiment is illustrated by taking a vortex pump as an example. The housing 5 has a pump chamber and a spacing chamber 11 formed therein, wherein the pump chamber occupies approximately 338 degrees of a full circle and the spacing chamber 11 occupies approximately 22 degrees of a full circle, as shown in fig. 5. The center of the impeller is provided with a connecting shaft 6.
The casing 5 is formed by combining a left casing 51 and a right casing 52, wherein the structures of the left casing 51 and the right casing 52 are symmetrically arranged, as shown in fig. 6 and 7, the left casing 51 comprises a left casing body 511, a left pump cavity 512 and a left spacing cavity 513 are arranged on the left casing body 511, correspondingly, the right casing 52 comprises a right casing body 521, and a right pump cavity 522 and a right spacing cavity 523 are arranged on the right casing body 521. After the left housing 51 and the right housing 52 are mutually spliced, the left pump chamber 512 and the right pump chamber 522 are enclosed to form a pump chamber, the left compartment 513 and the right compartment 523 enclose a compartment 11, the compartment 11 serving to block the inlet and outlet of gas or liquid. The impeller, when rotated in the pump chamber defined by the left 512 and right 522 pump chambers, drives gas or liquid from the inlet to the outlet, or gas or liquid enters from the inlet, drives the impeller to rotate around the combined pump cavity of the left pump cavity 512 and the right pump cavity 522, and then flows out from the outlet.
As shown in fig. 4, the left casing 51 and the right casing 52 are buckled with each other to mount the impeller into the inner cavity thereof, wherein a "C" type vortex cavity 7 is formed between the inner wall of the casing and the vane 3 (the "C" type vortex cavity 7 is located in the pump cavity enclosed by the left pump cavity 512 and the right pump cavity 522, and is marked as 7 in fig. 4), and due to the change of the shape of the vane 3, the strongest vortex flowing along the inner wall of the casing is dislocated with the gap 10 (shown in fig. 4) between the partition tongue of the casing and the impeller, so that a C type vortex section is formed, leakage at the gap can be reduced, pressure can be increased, and efficiency can be improved. The direction of gas and liquid entering the blade 3 is nearly consistent with the centrifugal force direction by forming a C-shaped vortex cavity between the first arc slope 31 of the impeller 3 and the inner wall of the shell and approaching to the included angle area 9 of the impeller center, and the C-shaped vortex cavity between the second arc slope 32 of the impeller 3 and the inner wall of the shell is approaching to the included angle area 8 of the periphery of the impeller, so that after gas and liquid come out from the blade, the vortex motion of the gas and the liquid can be enhanced, and noise is reduced. The annular support 4 is located near the center of the C-shaped vortex section (the 'C' -shaped vortex cavity 7), and has minimal influence on vortex, so that the efficiency of the pump is improved.
The ultra-thin blade formed by processing the metal sheet is arranged on the impeller, and the blades on the same side are connected with the annular bracket, so that the strength of the blade is ensured, and the annular bracket is positioned near the center of the vortex section, so that the influence on the vortex is minimal. As the thickness of the blade decreases, the resistance is smaller, the efficiency is improved, and the blade can be used in a wider range (such as a gas turbine or a water turbine). Experiments prove that under the condition that the input voltage and the current are the same, the output flow of the air pump using the impeller with the existing thickness and rectangular shape is 14.1 cubic meters per hour, the plugging air pressure is 3.5kPa, and the output flow of the air pump adopting the impeller is 51 cubic meters per hour, and the plugging air pressure is 7.1kPa.
The foregoing is merely illustrative embodiments of the present invention, and the present invention is not limited thereto, and any changes or substitutions that may be easily contemplated by those skilled in the art within the scope of the present invention should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
