Abstract

Provided is an oxygen increasing pump for the aeration in the biological oxygen increasing and sewage treatment processes, in particular a double impeller push flow type efficient aeration, oxygen increasing pump. The utility model includes a pump driven by the motor driving the coupling, an air duct, a float, a diversion joint at the export end of the pump, the utility model is characterized in that the main shaft lower end of the pump is installed with a secondary impeller and a main impeller in turn from upper to lower with intervals, the surrounding of the two impellers is provided with a conical ring shape cover, the cover wall is provided with a group of pylomes connecting the space inside the cover above the secondary impeller with the wind inlet space outside the cover. The utility model is characterized by efficient aeration and oxygen increasing, and reasonable and simple in structure, energy saving and etc.

Description

Bilobed wheel pulling flow type high efficient aeration, aeration pump

The utility model relates to a kind of aeration pump, especially bilobed wheel pulling flow type high efficient aeration, aeration pump that can be used for the aeration etc. in biological enhancementoxygen, the sewage treatment.

The efficient waterfall gas of the compound leaf pulling flow type that Chinese patent 99226192.9 provides, aeration pump, its deficiency is: its composite impeller assembly comprises the plug-flow impeller, and place plug-flow impeller front preceding centrifugal impeller, place the back centrifugal impeller of plug-flow impeller back; The structure more complicated of this composite impeller assembly, and increase because of the fluid resistance by it strengthens the power consumption make it.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of bilobed wheel pulling flow type high efficient aeration, aeration pump are provided, so that it has is simple in structure, economize on electricity, and working stability is reliable, the characteristics such as efficient height of aeration or oxygenation.

The utility model bilobed wheel pulling flow type high efficient aeration, aeration pump, it includes pump, airduct, the float that is driven by coupling by motor, the flow guiding head that is positioned at the pump discharge end, be characterized in: the main shaft lower end of pump has been installed sub-propeller and main impeller from top to bottom successively at interval, all sides of this two impeller are equipped with the circular cone circular cowling, and are provided with one group of through hole that can make the interior space of cover of sub-propeller top with the connection of the air intake space on the cover on the cover wall of this cover.

Use the utility model bilobed wheel pulling flow type high efficient aeration, during aeration pump, elder generation's actuating motor, and by the running of coupling drive pump, the sub-propeller and the main impeller that are positioned on the pump shaft are made high speed rotating thereupon, at this moment ambient air enters the air intake space on circular cone circular cowling top from airduct, not only the through hole on circular cone circular cowling cover wall enter the sub-propeller top negative pressure space and but also constantly downwards, be subjected to sub-propeller and the strong stirring of main impeller in its downward process, thereby bubble is pulverized, oxygen is dissolved in the current to the utmost in it, and this air-water mixture exhales to its all side by the opening end of the annulus column of flow guiding head bottom at last.

The utility model has the advantages that: 1) after making into composite impeller assembly of the prior art into bilobed wheel, the more reasonable structure of the utility model bilobed wheel pulling flow type aeration, aeration pump is more simplified, so its working stability is reliable, and, two impellers make it still have the characteristics of efficiently expose to the sun oxygen, oxygenation because of continuing keeping the rational structure shape; 2) bilobed wheel in the utility model not only makes designs simplification, and make by its fluid resistance significantly reduce, power consumption subtracts greatly, thereby it is a kind of energy-saving product, is convenient to people's being extensive use of its.

To and contrast accompanying drawing by embodiment below the utility model will be done narration further.Accompanying drawing thes contents are as follows:

Fig. 1 is the plan view (half sectional view is adopted in its bottom) of the utility model bilobed wheel pulling flow type high efficient aeration, aeration pump.

From Fig. 1, can see the utility model bilobed wheel pulling flow type high efficient aeration, oxygenation pump structure, it includes the pump 4 that driven by coupling 2 by motor 1, be positioned at airduct 5 on the pump week side, be positioned at the flow guiding head 9 of pump discharge end, the float 3 that pump is bubbled through the water column, and the circular cone circular cowling 7 that is positioned at the sub-propeller 6 of main shaft lower end of pump and main impeller 8, installs in all sides of major-minor two impellers.

Sub-propeller 6 and main impeller 8 go to upper and lower on the pump main shaft at interval and install, and sub-propeller 6 is on main impeller 8; Be provided with one group of through hole 10 that can make the interior negative pressure space I of cover of sub-propeller 6 tops on the cover wall of circular cone circular cowling 7 with the connection of the air intake space II on the cover.

The utility model bilobed wheel pulling flow type high efficient aeration, aeration pump are when work, elder generation's actuating motor 1, drive pump 4 runnings by coupling 2, the sub-propeller 6 and the main impeller 8 that are positioned on the pump shaft are made high speed rotating thereupon, at this moment ambient air from airduct 5 to air intake space II, through hole 10 on circular cone circular cowling 7 cover walls enters negative pressure space I in the cover of sub-propeller top again, and constantly advances downwards; Be subjected to the strong stirring of the sub-propeller 6 and the main impeller Final 8 in its downward process, thereby make bubble be pulverized and can be dissolved in to the utmost in the current, this air-water mixture exhales to its all side by the opening end of the annulus column of flow guiding head 9 bottoms at last; Therefore dissolved in a large amount of oxygen in the gas flow this moment, had and be biological enhancementoxygen or the effect of aeration in sewage.

Claims
