Embodiment

The present invention is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-11:

A kind of impeller of aerator, mainly by: bullet 1, blade 5, terminal pad 12 etc. are formed, bullet 1 and a plurality of blade 5 integrated injection moldings, bullet 1 is up big and down small conical shell, small end has filter screen 11; A plurality of windows 10 of crossing water are arranged on the bullet 1, in the window 10 grid are arranged, window 10 is arranged on the position of vacuum side of blade; Terminal pad 12 is fastenedly connected with bullet 1, and there is the installation position 13 and installing hole 14 that is connected with aerator at terminal pad 12 middle parts, on the terminal pad 12 aquaporin are arranged.

The filter screen 11 and bullet 1 injection mo(u)lding together of above-mentioned bullet small end, main muscle 7 is formed filter screen 11 with ring-like secondary muscle 8, and the runner when the main muscle 7 of filter screen 11 is injection moulding helps injection moulding and fills type.

The main muscle of the filter screen of above-mentioned bullet small end: according to the direction of rotation of impeller; The main muscle 7 upper surfaces direction that meets water is lower than the backwater direction; Upper surface becomes shaped form 39 or the linear 40 that the water lift function is arranged, and the water lift amount in the time of can increasing impeller work increases oxygenation effect.

The inboard of above-mentioned bullet 1 and terminal pad 12 connecting portions have reinforcing ring 2, make terminal pad 12 and bullet 1 combine more firm; There is back-up ring 3 reinforcing ring 2 inboards, and back-up ring 3 prevents that small fish and shrimp is stuck in the slit of bullet 1 and terminal pad 12 combinations.

The hole that above-mentioned terminal pad 12 is connected with bullet 1 is arranged on the annulus 16, and annulus 16 is connected by spoke 15 with installation position 13, or terminal pad 12 is not with annulus 16, and the hole that terminal pad 12 is connected with bullet 1 is arranged on the end of spoke 15.

Above-mentioned bullet 1 oral area limit rafter thickness is greater than bullet 1 wall thickness, around the window 10 reinforcement 9 arranged, and there is support strip at the back side of blade, makes bullet 1 and blade 5 more firm, and contraction distortion when reducing injection moulding.

The present invention has the aerator of this impeller; Connect reduction box by motor 17; The output shaft 28 of reduction box is connected through the installation position 13 of flange 26 and impeller, and impeller is rotated, described reduction box mainly by: casing 21, loam cake 20, double-reduction gear, bearing, output shaft 28 etc. are formed; Respectively there is the half slot that support bar 29 is installed the junction of casing 21 and loam cake 20, and support bar 29 1 ends are installed in the circular hole of loam cake 20 and casing 21 upper and lower half slots compositions; The other end of support bar 29 has retainer ring 31, and retainer ring 31 connects buoyancy aid, and aerator is kept afloat, and loam cake 20 can be cast into one with motor casing or make up with the motor casing split, makes aerator production realize not having cutting and few cut, the suitable production in enormous quantities in enormous quantities.

Above-mentioned buoyancy aid is spherical hollow blow molding spare, is called ball float 30, and retaining ring 33 is arranged on the ball float mouth, and retaining ring is shaped on the screw thread that cooperates with ball float lid 32 for 33 times, and the inwall that retaining ring 33 and ball float cover 32 tops has the space of backwater; Support bar 29 is mouldings with the retainer ring 31 that ball float cooperates; Retainer ring 31 is installed in backing plate 34 and the bolted of support bar 29 outer rafters with two holes; Retainer ring 31 is that the moulding cost is low; Retainer ring 31 does not have welding processing with support bar 29, prevents that effectively retainer ring 31 and support bar 29 are because of welding corrosion, fracture.The inwall that retaining ring 33 and ball float cover 32 tops has the space of backwater, can reduce seal request between the screw thread that ball float lid 32 and ball float lid 32 cooperate.Because impeller of the present invention and aluminium die casting reduction box weight reduce significantly; The less flat buoyancy aid of the other end available volume of support bar 29 is kept afloat aerator; The plane, both sides of flat buoyancy aid is parallel with support bar 29, and buoyancy aid reduces the resistance of current when making aerator work, improves oxygenation efficient.For the assembly direction of flat buoyancy aid and support bar 29 is reliably located, the end of support bar 29 and flat buoyancy aid faying face have buoyancy aid retainer ring 31, are shaped on groove in the retainer ring 31, on the flat buoyancy aid convex tendon are arranged, and convex tendon and groove fit make the directed installation of flat buoyancy aid.Flat buoyancy aid technology capability is good, transportation and packing cost reduce.

Above-mentioned reduction box is that the driver pinion 22 of secondary travelling gear is contained on the motor shaft; Drive one-level driven gear 23; 24 combinations drive secondary driven gear 25 to one-level driven gear 23 with shaft gear; The upper end bearing of shaft gear 24 is in the bearing chamber 37 of loam cake 20, and bottom end bearing is in the bearing chamber 38 of casing 21, and the bearing chamber outer end is sealed; Support bar 29 1 ends are installed in the circular hole of loam cake 20 and casing 21 upper and lower half slots compositions, and the turret head of hex bolts passes the hexagon ring 27 of loam cake 20, makes support bar 29 and casing fastening.

The foregoing description is merely one of preferred embodiment of the present invention, is not to limit protection scope of the present invention according to this, so: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.
