Abstract

The utility model discloses an impeller of the oxygen supplier with multiple water sprays, belonging to the technical field of the waters aerator. The impeller of the oxygen supplier with the multiple water sprays comprises a hollow reverse truncated cone impeller body, and the side surface of the periphery of the impeller body is distributed uniformly with a lower blade and an upper blade at space. The impeller body provided with a suction hole is covered with a flat plate, and a side surface along the upper blade of the impeller body is provided with a minor subsidiary blade which is formed into the certain included angle with the surface of the upper blade. Because of the fact that the utility model adds the subsidiary blade on the upper blade of the impeller, a triplet blade is formed on the impeller. In operation, the triplet blade generates three-layer water sprays, which increases the quantity of the supplying water further, improves the density of the water spray, and enlarges the aeration area and the dissolved oxygen area; consequently, the aeration efficiency is improved substantially the under the condition without increasing the size of the impeller.

Description

Many hydraulic jumps oxygen increasing machine impeller

Technical field

The utility model belongs to waters aerator technical field, relates to a kind of blade wheel structure of paddle aerator.

Background technology

At present, the paddle aerator that the oxygenation effect of culture fishery extensive use is preferable, its impeller is the inverse-umbrella type impeller, mistake is evenly equipped with two layers of blade of height between on the umbrella cover outer peripheral face, just produce two layers of hydraulic jump during the impeller rotation, being about to the waters superficial water breaks into fine and closely woven spray and rises in the air, make pernicious gas effusion in the water, inhale in the molten air new fresh oxygen simultaneously and return drowning territory, the impeller center forms certain negative pressure again in the rotation, air promptly enters the waters from the hole that impeller umbrella mouth plane cover plate is offered, and makes oxygen directly miscible in water body, thereby improves the dissolved oxygen amount and the water quality in waters effectively.

Summary of the invention

The purpose of this utility model is that the impeller that has paddle aerator now is carried out technological improvement, with the water lift amount and the fine and closely woven degree of spray of further raising impeller, thus the degassing and the dissolved oxygen oxygenation efficient of raising water.

The technical scheme that realizes above-mentioned purpose is: it comprises the hollow wheel body of falling the truncated cone shape, uniform following paddle and the last paddle of mistake between on the wheel body circumferential lateral surface, be provided with the wheel body loam cake flat board of suction hole, and along one lateral longitudinal of paddle on the wheel body to the less sub-paddle of blade that forms an angle with last paddle blade face is installed.

The utility model is owing to derive sub-paddle on paddle on the impeller, thereby just form triple paddles on the impeller, produce three layers of hydraulic jump during running, further increased the water lift amount, improved the fine and closely woven degree of spray, enlarge aeration area and dissolved oxygen area, do not increased under the condition of impeller size, increased substantially oxygenation efficient.

Embodiment

Wheel body 1 of the present utility model falls truncated cone shape for hollow, the uniform suction hole 6 that offers on the wheel body loam cake flat board 5, the wheel body center is equipped with turning cylinder 7, mistake is evenly equipped with some paddle 2 and last paddles 3 down between on the wheel body circumferential lateral surface, and a lateral longitudinal of last paddle 3 is to sub-paddle 4 is installed, have angle between the plane of sub-paddle 4 and last paddle 3, this angle is preferable with 45 °.

Claims

1, a kind of many hydraulic jumps oxygen increasing machine impeller, comprise the hollow wheel body of falling the truncated cone shape (1), uniform following paddle (2) and the last paddle (3) of mistake between on the wheel body circumferential lateral surface, be provided with the wheel body loam cake flat board (5) of suction hole (6), a lateral longitudinal that it is characterized in that paddle (3) is to the less sub-paddle (4) of blade that forms an angle with last paddle (3) blade face is installed.

2,, it is characterized in that the preferable angle between the plane of sub-paddle (4) and last paddle (3) is 45 ° by the described many hydraulic jumps oxygen increasing machine impeller of claim 1.
