The further proposal of the utility model is that the cone angle of the inverted cone structure of the water baffle projecting ring is controlled at 20-40 degrees, and the inclination angle of the arc-shaped blade is controlled at 35-55 degrees.

The further proposal of the utility model is that the upper edge of the water-retaining projecting ring is higher than the upper plane of the wheel seat.

The utility model discloses a further scheme, be equipped with the motor shaft fixed orifices fixed with motor output shaft on the last plane of wheel seat.

The utility model discloses a further scheme, be equipped with on the last plane of wheel seat with fixed orifices or guide pillar hole of motor output.

After adopting above-mentioned structure, compare with prior art and have following advantage and effect: firstly because the surface that the manger plate throws the circle is equipped with slope setting and evenly distributed's arc blade, be connected with the back pressure inner blade between the outer wall of wheel seat and the inner wall that the manger plate throws the circle, be equipped with vortex water conservancy diversion mouth on the wheel seat lateral wall, when impeller type oxygen-increasing machine operation during operation, the vortex produces thrust upwards to the impeller, can follow vortex water conservancy diversion mouth outflow punching press back pressure inner blade and make the impeller produce thrust downwards, it is steady from top to bottom to make impeller during operation, guarantee that impeller during operation draft remains unchanged basically, thereby reach the purpose of steady operation. And different connecting structures with the inner rotor motor and the outer rotor motor are arranged on the wheel seat, so that the wheel seat has good universality and is simple and convenient to install and fix.

Detailed Description

Fig. 1 to fig. 5 show, do the utility model discloses integral type oxygen-increasing machine impeller's specific embodiment, it includes wheel seat 1, is equipped with the open interior cavity 10 in lower part on the wheel seat 1, the lower edge of wheel seat 1 is connected with the manger plate casting circle 2 of back taper structure, and manger plate casting circle 2's surface is equipped with a plurality of slopes and sets up and evenly distributed's arc blade 9, forms the V-arrangement groove between wheel seat 1's outer wall and the inner wall of manger plate casting circle 2 and is connected with in the back pressure blade 6 corresponding with arc blade 9, and the bottom of blade 6 sets up to arc transition face 7 in the back pressure, is equipped with on the wheel seat 1 lateral wall between the blade 6 in the adjacent back pressure with interior cavity 10 intercommunication and with be close to the vortex water conservancy diversion mouth 8 of arc transition face 7. When the impeller type aerator operates, the impeller is used as the center to generate vortex, the vortex can generate upward thrust to the impeller in operation, meanwhile, the vortex flows out of the punching back-pressure inner blade 6 from the vortex flow guide port 8 through the inner cavity 10 and enables the impeller to generate downward thrust, so that the impeller operates stably from top to bottom, the higher the vortex rotation speed is, the larger the upward thrust generated to the impeller is, but the larger the downward thrust generated to the impeller by the vortex punching back-pressure inner blade 6 is, and therefore through the improvement of the structure, the draft of the impeller during operation can be guaranteed to be basically kept unchanged, and the purpose of stable operation is achieved.
