Abstract
The invention discloses a novel pump E-typed vertical surface aerator. A stirring blade which is fixed on a transmission shaft by a nut of the stirring blade and a sleeve is arranged at the bottom of an impeller; stirring rotation is carried out on the stirring blade under the driving of the transmission shaft; the stirring blade stirs sewage and promotes the water flow and pushes the water flow to the inlet of an aeration impeller, then aeration and oxygenation are carried out by the aeration impeller, so that the aeration and oxygenation for the sewage in the depth of an aeration tank are effectively achieved.
Description
Technical field
The present invention relates to a kind of pump E type vertical surface aerating machine of biochemical treatment of sewage work.
Background technology
At present, known pump E type vertical surface aerating machine is made up of electric motor, step-down gear, transmission shaft and impeller.Be positioned at the impeller of the following certain depth in surface, aeration tank, under the drive of transmission shaft, rotate, sewage is sucked through runner by impeller inlet to be thrown away at a high speed and forms hydraulic jump from outlet, liquid level is brought in constant renewal in, make sewage fully contact with air, airborne oxygen dissolves in the sewage effectively, finishes the oxygenation of sewage.But pump E type vertical surface aerating machine can only make the sewage of aeration tank upper layer stir aeration, and can't solve the stirring aeration problem of the depths of aeration tank.
Summary of the invention
Task of the present invention provides a kind of pump E type vertical surface aerating machine with stirring, and it has solved the problem that can not stir aeration to depths, aeration tank sewage in the prior art.
The present invention solve that its technical problem adopts technical scheme be:
A kind of novel pump E type vertical surface aerating machine, in the bottom of impeller one agitating vane is installed, agitating vane is fixed on the transmission shaft by agitating vane nut and axle sleeve, this agitating vane stirs rotation under the drive of transmission shaft, the agitating vane stirring-up sewage also promotes current, current are pushed to the ingress of aeration impeller, carry out aeration aerating by aeration impeller again, realize the aeration aerating of the sewage of depths, aeration tank effectively.
A kind of pump E type vertical surface aerating machine with stirring of the present invention is particularly useful for deep aeration tank, it utilizes the agitating vane under the pump E type vertical surface aerating machine impeller that the sewage of depths, aeration tank is stirred, the sewage of depths, aeration tank is stirred, and the sewage after stirring is pushed to the ingress of aeration impeller, carry out aeration aerating by aeration impeller again.

Specific embodiment:
As shown in Figure 1, the pump E type vertical surface aerating machine that is a kind of with stirring of the present invention, at the top is electric motor 18, it below electric motor 18 step-down gear 1, step-down gear 1 is connected with support 17 by joint bolt 2, in support 17, be provided with shaft coupling 3, realize being in transmission connection of step-down gear 1 and transmission shaft 5 by shaft coupling 3, transmission shaft 5 is realized radially fixing by bearing 4 and bearing 7, at the downside of shaft housing 6 impeller 9 is installed, impeller 9 is fixed on impeller nut on the transmission shaft 5 by joint bolt 14, realize radially fixing by fastening driving member 15, at the downside of impeller 9 agitating vane 11 is installed, agitating vane 11 is by agitating vane nut 10 and realize axial restraint, is fixed on the transmission shaft 5 by fastening driving member 12.
Referring to Fig. 2 to Fig. 4, that the blade of agitating vane 10 can be designed to is linear, cylinder shape with the spatial warping type.
Working process of the present invention is as follows:
Start pump E type vertical surface aerating machine, under nominal situation, electric motor drives the transmission shaft rotation by step-down gear and shaft coupling, agitating vane and impeller on the transmission shaft rotate simultaneously, under action of centrifugal force, the sewage that drives the depths, aeration tank by agitating vane stirs and the sewage that stirred is pushed near the impeller inlet place, suck by impeller again and under action of centrifugal force, sewage is thrown away at a high speed and forms hydraulic jump from outlet, liquid level is brought in constant renewal in, cause sewage fully to contact with air, a large amount of oxygen dissolves in the sewage in the air, finishes the oxygenation of sewage.
Advantage of the present invention is: the downside of impeller increases by a stirrer paddle, under the effect of stirrer paddle centrifugal force Make the sewage of depths, aeration tank stir and be pushed to the import department of aeration impeller, carry out aeration by aeration impeller and fill Oxygen has been realized the aeration aerating of depths, aeration tank sewage effectively.
The pump E type vertical surface aerating machine that this novel band stirs has good effect through on probation, is tried User's welcome.
