Abstract
The invention provides a kind of aerator with grinding mechanism, settle grinding mechanism in the water inlet of aerator; Described submersible machine is connected with hollow drive shaft by resilient coupling; Impeller is arranged on the other end of hollow drive shaft, and the axle head of impeller is connected with the axle of grinding mechanism by resilient coupling, and grinding mechanism is arranged on the axle head water inlet of hollow drive shaft.Under grinding mechanism turning effort, enter water-in rubbish thing, under the fast rotational of whetting a knife, rubbish thing is ground, thus the blockage problem etc. of water-in is very significantly improved, and expand the aeration efficiency of aerator.
Description
Technical field
The present invention relates to a kind of submersible aerator, especially a kind of submersible aerator with grinding mechanism.
Background technology
Aeration is a very important technical process in biochemical wastewater treatment, submersible aerator is by submersible machine impeller high speed rotating, impeller produces powerful centrifugal force, under the influence of centrifugal force, negative pressuren zone is formed around impeller, thus generation self-suction, by air suction pipe, a large amount of fresh airs in air are constantly sucked, sewage sucks again and attracts cover by impeller simultaneously, attracting the air generation gas-liquid of sewage and suction in cover to collide to form a large amount of superfine air bubbles to be sprayed to surrounding by diversion trench, the gas-liquid mixed ejected is miscarried the effect of life stirring convection current.And the blockage problem of priming device often appears in current aerator, need the cleaning of timing to attract the rubbish covered, ensure the unobstructed of priming device, but aerator is diving work, cleaning is a very loaded down with trivial details job.
Summary of the invention
The object of the invention is the blockage problem solving common submersible aerator prosopyle, a kind of submersible aerator with grinding mechanism is provided, adopt the water intake mechanism of band grinding mechanism, make the blockage problem of aerator water-in obtain improvement to a certain extent, and the aeration efficiency of aerator can be improved.
With a submersible aerator for grinding mechanism, comprise submersible machine, hollow drive shaft, resilient coupling, body, impeller, mixing section, mixing stator, spray tube, inlet pipe, it is characterized in that: settle grinding mechanism in the water inlet of aerator; Described submersible machine is connected with hollow drive shaft by resilient coupling; Impeller is arranged on the other end of hollow drive shaft, and the axle head of impeller is connected with the axle of grinding mechanism by resilient coupling, and grinding mechanism is arranged on the axle head water inlet of hollow drive shaft.
Preferably, described grinding mechanism is made up of movable knife disc and quiet cutterhead, and quiet cutterhead is fixed on water-in, and movable knife disc is placed on hollow drive shaft, the inside edge of described quiet cutterhead is provided with the identical semicircle prosopyle of multiple diameter, and movable knife disc outer ledge is provided with multiple sharpening.
Preferably, the diameter L1 of described semicircle prosopyle is less than the size L2 of sharpening.
Preferably, the diameter L1 of described semicircle prosopyle is 0.8 times of the size L2 whetted a knife.
Preferably, between described quiet cutterhead and movable knife disc, there is radius clearance.
Contrast prior art, beneficial effect of the present invention is as follows:
The water intake mechanism of the present invention to aerator improves, at the grinding mechanism that water-in is settled, the rubbish thing passed through from water-in can grind by atwirl sharpening, thus does not affect mixed indoor gas-liquid mixed, also can improve the blockage problem of prosopyle and fluidic device.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this.
Figure 1 shows that band of the present invention blends the structural representation of the aerator of grinding mechanism.Described aerator comprises submersible machine 1, hollow drive shaft 2, resilient coupling 3, body 4, impeller 5, mixing section 6, mixing stator 7, spray tube 8, inlet pipe 9.Grinding mechanism 10 has been settled at the water-in of aerator.Described submersible machine 1 is connected with hollow drive shaft 2 by resilient coupling 3; Impeller 5 is arranged on the other end of hollow drive shaft 2, and the axle head of impeller 5 is connected by the axle of resilient coupling 3 with grinding mechanism 10, and grinding mechanism 10 is arranged on the axle head water inlet of hollow drive shaft 2.Submersible machine 1 is connected to it by resilient coupling 3 and hollow drive shaft 2 and provides power; Impeller 5 rotates together with hollow drive shaft 2, and the axle head of impeller 5 is connected with the axle of grinding mechanism 10 by resilient coupling 3, and grinding mechanism 10 rotates with driving tubular shaft.
As shown in Figure 2 and Figure 3, grinding mechanism 10 is made up of movable knife disc 11 and quiet cutterhead 12, quiet cutterhead 11 is fixed on water-in, movable knife disc 12 is placed on hollow drive shaft 2, with driving tubular shaft fast rotational, the inside edge of described quiet cutterhead 12 is provided with the identical semicircle prosopyle 13 of multiple diameter, and movable knife disc 11 outer ledge is provided with multiple sharpening 14.The diameter L1 of described semicircle prosopyle 13 is less than the size L2 of sharpening 14.Preferably, the diameter L1 of described semicircle prosopyle 13 is 0.8 times of the size L2 of sharpening 14, has certain radius clearance between quiet cutterhead 11 and movable knife disc 12.
Described embodiment is preferred embodiment of the present invention; but the present invention is not limited to above-mentioned embodiment; when not deviating from flesh and blood of the present invention, any apparent improvement that those skilled in the art can make, replacement or modification all belong to protection scope of the present invention.
