impeller

Technical field

The present invention relates to the field of exhaust or drainage treatment, and in particular to an air thrust component.

Background technique

At present, there are many devices that rely on air or water to do work. For example, blowers or pumps, etc., rely on the impeller to produce a certain thrust or pressure. There are many types of impellers, and the impellers are also various. The more common impeller is a fan-shaped blade, which has a small amount of suction and a relatively large volume. At present, after a common impeller reaches a certain pressure or temperature, it is easy to produce deformation or breakage, high noise and low work efficiency.

Summary of the invention

It is an object of the present invention to provide an impeller that addresses one or more of the above prior art problems.

According to an aspect of the present invention, an impeller includes an impeller body and an air outlet passage axially disposed on the impeller body. The impeller body has a plurality of air inlet portions, and the air outlet passage communicates with the air inlet portion, and each air intake portion is disposed. The partition baffle partitions the air inlet into a plurality of intake passages, and each of the intake passages is connected to the outlet passage at one end.

The impeller provided by the invention is provided with a plurality of inlet passages, which increases the suction port compared with the existing impeller, increases the total amount of the treatment medium, has small volume, no leakage, and improves work efficiency. Multi-layer distribution, forced laminar motion of high-speed gas, reducing the occurrence of turbulence, increasing the amount of intake air, high mechanical strength, and low noise.

In some embodiments, the projection of the spacer baffle in the axial direction of the impeller body is curved. Helps balance the air pressure throughout the air passage, further reducing noise.

In some embodiments, the air inlet portion is flared, and the air inlet passage and the air outlet passage are smoothly transitioned. Reduced air flow resistance and loss, and the runner structure makes it stronger, not Variable or damaged.

In some embodiments, the inner diameter of the outlet passage gradually increases in the direction of the gas flow of the outlet passage. It helps to balance the air pressure of the air outlet passage so that each air intake passage has the same pressure.

In some embodiments, the impeller body includes a plurality of wheel bodies, a plurality of wheel bodies are stacked, and a spacer baffle is fixed between the adjacent two wheel bodies, and the partition baffle partitions the space between the adjacent two wheel bodies. In a plurality of intake passages, the diameter of the wheel body sequentially increases in the direction of the air flow of the outlet passage.

In some embodiments, the spacers on either side of the same wheel body are fixed at different positions of the wheel body. The increasing diameter of the inlet passage helps the compression ratio of the gas in each layer of the inlet passage to be consistent, maximizing efficiency.

detailed description

The invention will now be described in further detail with reference to the drawings of the specification.

As shown in FIG. 1-6, the impeller provided by the present invention comprises an impeller body 1 and an air outlet passage 2 disposed axially on the impeller body 1. The impeller body 1 is provided with a plurality of air inlet portions 5, an air outlet passage 2 and an air inlet. Part 5 is connected.

Preferably, the impeller body 1 of the present invention comprises a plurality of wheel bodies 6, a plurality of wheel bodies 6 are stacked, and a gap between two adjacent wheel bodies 6 forms an air inlet portion 5 between adjacent two wheel bodies 6. A spacer baffle 3 is fixed, and the partition baffle 3 divides the space between the adjacent two wheel bodies 6 into a plurality of independent intake passages 11.

Thus, the partition baffle 3 divides the intake portion 5 into a plurality of intake passages 11 for each intake air. Each of the passages 11 is connected to the outlet passage 2 at one end.

In order to facilitate a smooth transition of the air flow within the air outlet passage 2, the projection of the spacer baffle 3 in the axial direction of the air outlet passage 2 is curved.

Further, the air inlet portion 5 is distributed in a flared shape, and the connection between each of the air inlet passages 11 and the air outlet passage 2 is smoothly transitioned. It ensures that the airflow smoothly enters the air outlet passage 2 from the intake passage 11, which reduces the loss of gas and improves the working efficiency of air compression. As shown in FIG. 3, the flared portion of the intake portion 5 allows the intake passage 11 to have a stepwise upward curve. Further, the outlet passage 2 can be tangential to the intake passage 11 as much as possible to form a complete and smooth Air flow channel.

Further, in the air flow direction of the air outlet passage 2, the inner diameter of the air outlet passage 2 is gradually increased. It helps to balance the air pressure of the outlet passage 2 such that each intake passage 11 has the same pressure.

Further, as shown in FIG. 5, further, in the airflow direction of the air outlet passage 2, the diameter of the wheel body 6 is sequentially increased. It helps the smooth outflow of gas, and the compression ratio between the inlet passages of each layer is consistent, and the efficiency is maximized.

As shown in FIG. 6, preferably, the spacers 3 on both sides of the same wheel body 6 are fixed to different positions of the wheel body 6. The staggered layout helps to improve the deformation resistance of the top wall of the impeller.

In the present embodiment, the plurality of wheel bodies 6 constituting the impeller body 1 are integrally provided with the partitioning baffle 3, but they do not have a limiting effect on the specific mounting manner.

It should be noted that the outlet passage 2 of the present invention is intended to communicate with the intake passage 11, and the outlet passage 2 shown in Fig. 1 seems to be designed throughout the impeller body 1, but in practice, the reference numerals shown in Fig. 3 4 is a mounting hole, and the mounting hole 4 is disposed at one end of the impeller body 1. The mounting hole 4 is driven by the transmission device to drive the impeller body 1 to rotate.

The above description is only a preferred mode of the present invention, and it should be noted that various modifications and improvements can be made by those skilled in the art without departing from the inventive concept. Within the scope of protection.
