Abstract

The invention discloses an impeller for a stirrer, which is a hyperboloid impeller body, wherein the middle part of the hyperboloid impeller body is provided with a shaft hole connected with a rotating shaft of the stirrer, the hyperboloid impeller body is provided with a plurality of arc-shaped aeration channels from top to bottom, each arc-shaped aeration channel comprises a front aeration channel and a rear aeration channel, the front aeration channel is an inner channel in the hyperboloid impeller body, the rear aeration channel is a groove formed in the surface of the hyperboloid impeller body, and a stirring blade with a hollow inner part is covered on the groove. The advantages are that: can make liquid make tangential motion along the impeller circumferencial direction through the hyperboloid structure transition under acceleration of gravity's effect, under the reflex action of pool wall, form top-down ground circulation rivers, through the arc aeration passageway from top to bottom, carry out the aeration of natural aspiration formula simultaneously, need not to add aeration equipment in addition, improved stirring aeration effect, have the cost that relatively reduces simultaneously.

Description

Impeller for stirrer

Technical Field

The invention relates to an impeller for a stirrer, and belongs to the technical field of sewage treatment.

Background

In municipal, chemical and paper-making and other various water treatment processes, water stirring and mixing are one of the key processes. The traditional stirring machinery is divided into two common modes of a vertical shaft folding paddle type and a horizontal (diving) type, and the stirring form is determined by the installation mode and the paddle form, so that the stirring form is not ideal in energy consumption or stirring effect, unnecessary increase is brought to the operation cost of a sewage plant, the final process treatment effect can be directly influenced, and the problem that how to improve the stirring effect and the aeration efficiency under the condition of reducing the cost as much as possible needs to be solved at present is solved.

Disclosure of Invention

The technical problem to be solved by the invention is to overcome the defects of the prior art and provide an impeller for a stirrer.

In order to solve the technical problems, the invention provides an impeller for a stirrer, wherein the impeller is a hyperboloid impeller body, the middle part of the hyperboloid impeller body is provided with a shaft hole connected with a rotating shaft of the stirrer, the hyperboloid impeller body is provided with a plurality of arc-shaped aeration channels from top to bottom, each arc-shaped aeration channel comprises a front aeration channel and a rear aeration channel, each front aeration channel is an inner channel in the hyperboloid impeller body, each rear aeration channel is a groove formed in the surface of the hyperboloid impeller body, and each groove is covered with a stirring blade with a hollow inner part.

Further, at least the cross section of the stirring blade from the lower part is a triangle which is gradually reduced.

Furthermore, the top surface of the hyperboloid impeller body is provided with a plurality of air holes communicated with the arc-shaped aeration channel.

Furthermore, the lower end surface of the stirring blade is provided with an isolation net.

Further, a plurality of arc-shaped aeration channels are uniformly arranged in the hyperboloid impeller body.

Further, the lower end of the stirring blade is arranged at the lower edge of the hyperboloid impeller body.

Further, an air pipe is arranged on the air hole.

The invention achieves the following beneficial effects:

the impeller for the stirrer can ensure that liquid does tangential motion along the circumferential direction of the impeller through hyperboloid structure transition under the action of gravity acceleration, forms circulating water flow from top to bottom under the reflection action of the tank wall, and performs natural air suction type aeration through the arc-shaped aeration channel from top to bottom without adding additional aeration equipment, thereby improving the stirring aeration effect and relatively reducing the cost.

Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 (for convenience of explanation, a perspective view of one of the arc-shaped aeration channels is drawn in the figure), an impeller for a blender is provided, the impeller is a hyperboloid impeller body 1, a shaft hole 7 for connecting a rotating shaft 2 of the blender is arranged in the middle of the hyperboloid impeller body 1, the hyperboloid impeller body 1 is provided with a plurality of arc-shaped aeration channels 4 from top to bottom, the arc-shaped aeration channels 4 comprise a front aeration channel and a rear aeration channel, the front aeration channel is an inner channel inside the hyperboloid impeller body 1, the rear aeration channel is a groove formed in the surface of the hyperboloid impeller body 1, and the groove is covered with a hollow stirring blade 3.

In this embodiment, at least the cross section of the stirring blade 3 from the bottom is a triangle which is gradually reduced.

In this embodiment, the top surface of the hyperboloid impeller body 1 is provided with a plurality of air holes 6 communicated with the arc-shaped aeration channel 4, and the air holes 6 are provided with air pipes 8 for inputting air.

In this embodiment, the lower end surface of the stirring blade 3 is provided with an isolation net 5. Is used for preventing impurities such as underwater sludge or weeds and the like from entering the arc-shaped aeration channel and blocking the channel.

In this embodiment, a plurality of arc-shaped aeration channels 4 are uniformly arranged in the hyperboloid impeller body 1.

In this embodiment, the lower end of the stirring blade 3 is arranged at the lower edge of the hyperboloid impeller body 1.

The surface of the hyperboloid impeller body 1 is a gradually-opened double-cambered surface, through six or eight stirring blades 3 uniformly arranged on the surface, potential energy obtained by supplementing water by virtue of the self-weight pressure of liquid and centrifugal force generated when the impeller rotates form kinetic energy, the liquid makes tangential motion along the circumferential direction of the impeller through hyperboloid structure transition under the action of gravity acceleration, circulating water flow from top to bottom is formed under the reflection action of the pool wall, meanwhile, natural suction type aeration is carried out through the arc-shaped aeration channel 4 from top to bottom, additional aeration equipment is not needed, the stirring aeration effect is improved, and meanwhile, the cost is relatively reduced.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
