Abstract
The utility model relates to the technical field of environmental protection, in particular to a blade back-bending type high-efficiency double-suction impeller; the oil-water separating device comprises a wheel hub, double suction ports, a wheel disc and blades, wherein the front end and the rear end of the wheel disc are provided with the double suction ports, the wheel hub is rotatably arranged in the wheel disc, the blades are arranged on the periphery of the wheel disc, a shaft tube is inserted into a middle shaft of the wheel hub, and a plurality of metal rods are respectively arranged at the front end and the rear end of the shaft tube and have the function of scattering oil-water layers in a water body by utilizing the metal rods on the shaft tube along with the rotation of the shaft tube, so that the uniformity of an oil-water mixture entering the wheel disc is improved, and in addition, objects such as agglomerated dust; when sewage pressed in from the outside is close to two ends of the shaft tube, if oil-water layering exists, an oil-water layer can be scattered by the metal rod, so that the sewage is uniformly sucked into the wheel disc, and if agglomerated dust or slurry exists, the agglomerated dust or slurry is smashed into turbid liquid which can be smoothly thrown out after entering the wheel disc.
Description
Technical Field
The utility model belongs to the technical field of the environmental protection technique and specifically relates to a high-efficient double suction impeller of curved formula of blade back of body.
Background
Double suction impellers are commonly used in double suction water pumps to act on the liquid. There are, of course, a few manufacturers who apply them to sewage treatment processes.
The sewage is difficult to throw out by the double-suction impeller of the double-suction pump under two conditions, one is the sewage containing more grease, and because the oil and water are seriously layered, and the water inlet of the double-suction impeller is round, water with better fluidity can enter preferentially and the grease is easy to float outside; the other is sewage containing more insoluble dust, and because the insoluble dust is easy to be adhered and agglomerated in water, if the insoluble dust is directly fed into a water inlet, the insoluble dust can cause abrasion of an internal centrifugal blade.
Disclosure of Invention
To the deficiency of the prior art, the utility model provides a be convenient for various sewage misce benes get into internal double suction impeller.
The technical scheme of the utility model is that:
a blade back-bending type efficient double-suction impeller comprises a hub, double suction ports, a wheel disc and blades, wherein the double suction ports are formed in the front end and the rear end of the wheel disc, the hub is rotatably mounted in the wheel disc, the blades are arranged on the periphery of the wheel disc, the periphery of the wheel disc is hollow in places where the blades are not arranged, and a water body can be thrown out by centrifugal force applied by the blades along the hollow positions; the method is characterized in that: the wheel hub axis department has inserted a central siphon, a plurality of metal poles are all installed to the central siphon front and back end, and its effect is along with the rotation of central siphon, utilizes the metal pole on the central siphon to break up the profit layering in the water to improve the degree of consistency that oil water mixture got into the rim plate, can also smash objects such as some conglomerations dust, mud in addition, prevent that it directly gets into in the rim plate.
Furthermore, the shaft tube is made of stainless steel, so that the waterproof and antirust capabilities are improved.
Furthermore, the metal rod is made of light aluminum alloy, stress of the shaft tube is reduced, and the outer surface of the metal rod is plated with crystals, so that the wear resistance is improved.
Furthermore, the number of the metal rods arranged at the front end and the rear end of the shaft tube is equal.
Further, the length of the metal rod is smaller than the inner diameter of the double suction port. Too long a metal rod consumes more energy.
Further, the internal diameter of two suction openings is 427 millimeters, and wheel hub outer end face diameter is 180 millimeters, and the rim plate diameter is 692 millimeters, and the blade diameter is 672 millimeters.
Furthermore, back-bending type blades are arranged on the front end face and the rear end face of the hub.
The utility model has the advantages that: when sewage pressed in from the outside is close to two ends of the shaft tube, if oil-water layering exists, an oil-water layer can be scattered by the metal rod, so that the sewage is uniformly sucked into the wheel disc, and if agglomerated dust or slurry exists, the agglomerated dust or slurry is smashed into turbid liquid which can be smoothly thrown out after entering the wheel disc.
