Technical Field
The utility model belongs to the technical field of impellers, and particularly relates to an impeller for a gas-water mixing oxygenation pump.
Background
In the fields of aquaculture, sewage treatment and the like, in order to increase the oxygen content in water, oxygenation needs to be performed by an oxygenation pump. The impeller of the oxygenation pump currently used comprises a spiral outer sleeve, an inner sleeve, an outer blade positioned at the outer side of the outer sleeve and an inner blade positioned between the outer sleeve and the inner sleeve, wherein a stirring blade is arranged at the front end of the outer sleeve, oxygen or air enters from a channel between the inner sleeve and the outer sleeve, and the front end of the outer sleeve is mixed with water through the stirring blade. The impeller has the following defects: firstly, gas enters from a channel between the inner sleeve and the outer sleeve, is mixed with water at the front end of the outer sleeve through a stirring sheet, the contact area of the gas and the liquid is small, the gas and the liquid are unevenly mixed, the gas content in the liquid is low, and the oxygenation effect is poor; secondly, the gas contacts with the liquid at the front end of the outer sleeve, the volume of the bubbles is large, and the bubbles with large volume easily rise to the liquid surface and break under the action of buoyancy, so that the gas content in the liquid is low.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the impeller for the gas-water mixing oxygenation pump, which has high gas content in liquid and good oxygenation effect.
In order to solve the problems, the impeller for the gas-water mixing oxygenation pump adopts the following technical scheme: the stirring device comprises a spiral outer sleeve, an inner sleeve, an outer blade positioned at the outer side of the outer sleeve and an inner blade positioned between the outer sleeve and the inner sleeve, wherein a stirring piece is arranged at the front end of the outer sleeve, and a liquid side inlet is arranged on the outer sleeve close to the front end of the outer blade.
The additional technical characteristics are as follows:
a pointed bulge is arranged on the inner side surface of the outer sleeve at the front end of the liquid side inlet;
the pointed bulge is a triangular prism or a triangular pyramid;
the cross section of the stirring sheet is wedge-shaped, wherein one side of the stirring sheet is thick and the other side of the stirring sheet is thin in the rotating travelling direction.
Compared with the prior art, the impeller for the air-water mixing oxygenation pump provided by the utility model has the following advantages: firstly, because the impeller comprises a spiral outer sleeve, an inner sleeve, an outer blade positioned at the outer side of the outer sleeve and an inner blade positioned between the outer sleeve and the inner sleeve, a stirring blade is arranged at the front end of the outer sleeve, a liquid side inlet is arranged on the outer sleeve close to the front end of the outer blade, in the rotating process of the impeller, liquid positioned at the outer side of the outer sleeve enters a channel between the outer sleeve and the inner sleeve through the liquid side inlet and is primarily fused with gas in the channel to form a plurality of bubbles, and when the bubbles reach the front end of the outer sleeve, the stirring blade further breaks up the bubbles to form smaller bubbles, the gas and the liquid are more uniformly mixed, the gas content in the liquid is increased, and the oxygenation effect is further improved; secondly, as the pointed bulge is arranged on the inner side surface of the outer sleeve at the front end of the liquid side inlet, when the impeller rotates, the pointed bulge on the inner side surface of the outer sleeve breaks large bubbles and is combined with liquid in a channel between the outer sleeve and the inner sleeve to form bubbles with smaller volume, so that the contact area of the liquid and the gas is greatly increased, and the oxygenation effect is better; thirdly, as the pointed bulge is a triangular prism or a triangular pyramid, bubbles are easier to puncture; fourth, because the cross section of stirring piece is the wedge that rotates advancing direction one side thick, the opposite side is thin, has increased the beating area of stirring piece, forms certain space in beating the face rear moreover, is more convenient for the mixture of gas and liquid.

FIG. 2 is a cross-sectional view A-A of FIG. 1;
fig. 3 is a bottom view of fig. 1.
Description of the embodiments
The structure and the use principle of the impeller for the gas-water mixing oxygen-increasing pump of the utility model are further described in detail below with reference to the accompanying drawings and the specific embodiments.
As shown in fig. 1, 2 and 3, the impeller for the gas-water mixing and oxygenation pump of the present utility model comprises a spiral casing 1, an inner casing 2, an outer blade 3 positioned outside the casing 1, and an inner blade 4 positioned between the casing 1 and the inner casing 2, wherein a stirring blade 5 is arranged at the front end of the casing 1, and a liquid side inlet 6 is arranged on the casing 1 near the front end of the outer blade 3.
In the impeller rotation process, liquid positioned on the outer side of the outer sleeve 1 enters a channel 7 between the outer sleeve 1 and the inner sleeve 2 through a liquid side inlet 6 and is primarily fused with gas in the channel 7 to form a plurality of bubbles, when the bubbles reach the front end of the outer sleeve 1, the stirring sheet 5 further breaks the bubbles to form smaller bubbles, the gas and the liquid are more uniformly mixed, the gas content in the liquid is increased, and the oxygenation effect is further improved.
The inner side surface of the outer sleeve 1 at the front end of the liquid side inlet 6 is provided with the pointed bulge 8, when the impeller rotates, the pointed bulge 8 positioned on the inner side surface of the outer sleeve 1 breaks large bubbles, and the gas in the broken bubbles is combined with the liquid in the channel between the outer sleeve and the inner sleeve to form bubbles with smaller volume, so that the contact area between the liquid and the gas is greatly increased, and the oxygenation effect is better.
The pointed bulge 8 is a triangular prism or a triangular pyramid, so that bubbles are more easily punctured.
The cross section of the stirring sheet 5 is wedge-shaped, wherein one side of the stirring sheet in the rotating travelling direction is thick, and the other side of the stirring sheet is thin, so that the beating area of the stirring sheet is increased, a certain space is formed behind the beating surface, and the mixing of gas and liquid is facilitated.
The protection scope of the present utility model is not limited to the above embodiments, and falls within the protection scope of the present utility model as long as the structure is the same as or similar to the structure of the impeller for the air-water mixing and oxygenation pump of the present utility model.
