Description

A kind of submersible water impeller blade

Technical field

A kind of blade, especially submersible water impeller are the utility model is related to, more particularly a kind of High-strength light-weight section Can type submersible water impeller blade.

Background technology

In engineering of water treatment (especially wastewater treatment), submersible water impeller is indispensable significant components --- to current The part of mixed flow is stirred, and impeller blade is the most important functions part of this component.Because impeller exists for a long time Underwater operation, it is desirable to which it possesses high reliability, low energy consumption, high efficiency.Quite high, submersible water impeller is required to blade in sewage disposal It is mainly used in the stirring of flocculation, stirring in biochemical filler pond etc., the speed of blade is not high, but is relatively large in diameter, and can't damage Filler in pond, therefore surface need have cladding；Blade in the market is more using the swept-back Banana Type for comparing sizing Paddle type.Blade is had by two-chip type or three-chip type, structure：Aluminium core skeleton polyurethane cladding leaf slurry and foam core fiberglass cladding leaf slurry Etc. a variety of.With larger diameter, rotary speed does not include height.

Aluminium core polyurethane blade is currently the high one kind of Reliability comparotive, but from great, shaft core and aluminum component poor bonding strength, Impact resistance overload property is poor, is not suitable for the high-revolving requirement of low-power, and cost is also high.

The deadweight of iron frame polyurethane leaf oar has decline, but is welding product, and quality stability is poor, surface irregularity, also not It is adapted to high-revolving requirement.

Foam glass steel leaf oar, it is in light weight, cheap, but the material and technical matters that use at present are immature, damage Probability is very high, poor reliability.

Utility model content

The purpose of the utility model is to overcome the shortcomings of existing various submersible water impeller blades, proposes a kind of all steel integration Elastic skeleton, the Novel leaf oar of special high-strength polyurethane sizing material is coated, the product of high cost performance is provided for client.

The technical solution of the utility model is a kind of submersible water impeller blade, it is characterized in that including blade skeleton and cladding The PU material layers on skeleton, blade skeleton is welded steel axle, steel disc in flange and blade, is coated on PU materials on skeleton The bed of material is in blade die for molding.

The utility model is based on the basis of the various leaf oar features of in the market, employs the steel construction material of weldedization Material：PU material layers are to be capable of the special material of water-fast wear-resisting scratch-resisting wiping, including steel disc is flexible in steel axle, flange and blade With the material of toughness, the big big specification leaf oar of the utility model selection stress, can be reached most using current conventional diving motor Big measurement of rotating speed, and (aluminium and steel shaft are difficult fusion to existing aluminium core, it is necessary to have sufficiently long axle to be embedded to when aluminium core is cast, aluminium Casting must have enough thickness, just can guarantee that bulk strength, so heavier in weight) polyurethane leaf oar does contrast test, ties Fruit proves that the utility model new construction leaf oar has the reliability and economy of maximum.

Beneficial effect, above measured data can be seen that Novel leaf oar weight and decline 24% and 19%, structural flexibility respectively Increase.When 1800 leaf oar rotating speeds improve 53%, electric current declines 27%；When 2500 leaf oar rotating speeds improve 44%, electric current declines 16%；In the case where equipment is constant, realize propulsive efficiency improve 53% and 44%, energy consumption decline 27% and 16% it is surprising Effect.

Brief description of the drawings

Fig. 3 is the utility model structure diagram；

Fig. 4 is Fig. 3 cross-sectional structure schematic diagram.

Embodiment

As illustrated, including blade skeleton and being coated on PU material layers on skeleton, blade skeleton is welded steel Steel disc in axle, flange and blade, PU material layers are coated on skeleton in blade die for molding.

As illustrated, PU material layers 1, flange 2, steel axle 3, connecting screw 4, aluminium core 5, steel disc 6, reinforcement 7.

The aluminium core 5 of the shaping of No.1 substantially smaller than blade section is needed in the prior art, does not otherwise adapt to intensity Need, the proportion 2.7 of aluminium, and the proportion of PU material layers 1 is 1 or so；Flange 2, steel axle 3, steel disc 6 in the utility model One, the intensity of steel disc are far above aluminium, as long as therefore thin slice, steel disc make it that the rigidity of blade is more preferable provided with reinforcement 7.Add Strengthening tendons can be that the mode of welding or stalloy are folded into reinforcement shaping.

Those of ordinary skills in the art should understand that：The foregoing is only specific embodiment of the utility model and , the utility model is not limited to, it is all within the spirit and principles of the utility model, it is any modification for being made, equivalent Replace, improve etc., it should be included within the scope of protection of the utility model.

Claims (2)
