The utility model relates to a kind of stirring apparatus on pollution discharge pump, comprise stirring shaft, the excircle of described stirring shaft is evenly distributed with several paddles, paddle is triangular in shape on the cross section vertical with radius, namely the thickness to front side on rear side of paddle reduces gradually, and a cutting edge towards paddle sense of rotation is formed in front side, the end of described stirring shaft is provided with the first baffle plate, second baffle is provided with at the certain position place away from the first baffle plate, the stirring rod that many are positioned at distance baffle center different distance is installed between the first baffle plate and second baffle.The stirring apparatus that the utility model provides, can prevent Filament-wound Machine in fibre body medium, surface trimming Filament-wound Machine body, reduces running resistance, improves stirring efficiency; By arranging stirring rod, make to stir more even, stirring wheel more easy cleaning.
Description
Technical field
The utility model relates to blowdown field, water power plant, particularly relates to a kind of stirring apparatus on pollution discharge pump.
Background technique
Water power plant is the integration engineering facility that water can be converted to electric energy, generally comprises the reservoir and Diversion system of hydropower station, power plant building, electromechanical equipment etc. that are formed by dash, outlet structure escape works.The high water level water of reservoir flows into factory building promotion turbine-generator units through diversion system and sends electric energy, then through boosting transformer, switchyard and electric transmission line input electrical network.In many rivers, due to the destruction of upstream, river basins vegetation, and in ascendant trend year by year, unit flow passage components wearing and tearing aggravation, rotating wheel upper leak-proof ring gap expands rapidly, and top cover upper cavity pressure significantly rises, and causes water seal wearing and tearing and water leakage significantly to increase.
In pollution discharge pump working procedure, because in medium, solid matter is more, fluid is uneven, large to the impeller running resistance of pump, and forms shock, and the operational shock of pump is large, serious wear; And fibrous media is easily wound around impeller and forms obstruction, makes pump mechanical property decline, decrease in efficiency.For improving above-mentioned defect, common liquid sewage pump can install one from stirring wheel, to improve uniformity and the mobility of medium on the pump shaft of inlet.Existingly generally include a wheel disc be connected on axle sleeve from stirring wheel construction, circumferential paddle is set on the surface in wheel disc side.Have though this certain certainly stir effect from stirring wheel construction, its run in fibrous media be easily wound around, axial force is upwards increased, and air horsepower increases, the decrease in efficiency of pump.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of stirring apparatus on pollution discharge pump, can reduce running resistance, improves stirring efficiency.
The utility model is achieved through the following technical solutions:
A kind of stirring apparatus on pollution discharge pump, comprise stirring shaft, the excircle of described stirring shaft is evenly distributed with several paddles, paddle is triangular in shape on the cross section vertical with radius, namely the thickness to front side on rear side of paddle reduces gradually, and a cutting edge towards paddle sense of rotation is formed in front side, the end of described stirring shaft is provided with the first baffle plate, be provided with second baffle at the certain position place away from the first baffle plate, the stirring rod that many are positioned at distance baffle center different distance is installed between the first baffle plate and second baffle.
As optimal technical scheme of the present utility model, described cutting edge is curved.
As optimal technical scheme of the present utility model, the central position of described first baffle plate and second baffle offers mounting hole.
As optimal technical scheme of the present utility model, described stirring rod is cylindricality or square.
Compared with prior art, the beneficial effects of the utility model are: the stirring apparatus that the utility model provides, and can prevent Filament-wound Machine in fibre body medium, surface trimming Filament-wound Machine body, reduce running resistance, improve stirring efficiency; By arranging stirring rod, make to stir more even, stirring wheel more easy cleaning.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: 1-stirring shaft; 2-paddle; 3-cutting edge; 4-first baffle plate; 5-second baffle; 6-stirring rod; 7-mounting hole.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is plan view of the present utility model, and Fig. 2 is left view of the present utility model.
Described a kind of stirring apparatus on pollution discharge pump, comprise stirring shaft 1, the excircle of described stirring shaft 1 is evenly distributed with several paddles 2, paddle 2 is triangular in shape on the cross section vertical with radius, namely the thickness to front side on rear side of paddle 2 reduces gradually, and a cutting edge 3 towards paddle sense of rotation is formed in front side, described cutting edge 3 is curved.Can prevent Filament-wound Machine in fibre body medium, surface trimming Filament-wound Machine body, the paddle of the triangular-section current that are in operation can produce axially upwardly power, and medium is by certainly stirring paddle effect, pump inlet speed increases, medium entrance drag reduction, and hydraulic efficiency improves.In addition, the cutting edge of circular arc, when contacting fibre body, due to the effect of peripheral force, makes fibre body rub on blade, reaches preferably cutting effect; Crystalline particle clashes into by nose angle, reaches crushing effect, reduces pump impeller flow passage resistance force of waterproof.
The end of described stirring shaft 1 is provided with the first baffle plate 4, second baffle 5 is provided with at the certain position place away from the first baffle plate 4, the stirring rod 6 that many are positioned at distance baffle center different distance is installed between the first baffle plate 4 and second baffle 5, the central position of described first baffle plate 4 and second baffle 5 offers mounting hole 7, and described stirring rod 6 is in cylindricality or square.By arranging stirring rod, make to stir more even, stirring wheel more easy cleaning.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
