Description
Technical field
The utility model relates to a kind of gas-liquid mixed equipment, particularly a kind of self-suction gas-liquid mixing impeller.
Background technology
The Self inhaling type gas-liquid mixing impeller is the negative pressure of utilizing impeller to produce in the High Rotation Speed process under liquid, and gas is caused impeller from the hollow shaft of drives impeller or the sleeve outside the axle, and by impeller the form of gas with microbubble is scattered in the liquid.It can be used for chemical reaction field between gas-liquid, improves mass-transfer efficiency, simplified apparatus structure; Can also be used for the fields that are separated such as the separation of liquid liquid and liquid-solid separation, as removing the pollutants such as solids, oil and fiber in the sewage, pollutant is adhered on the microbubble, and rise to the water surface with microbubble, realize that separated from contaminants and water purify purpose.Because gas-liquid mixing impeller has the functions such as bleed, gas-liquid mixed simultaneously, can the simplified apparatus structure, various auxiliary devices in the cancellation legacy equipment, no matter economically, still all has technically obvious advantage, can be widely used in the fields such as water treatment, exhaust-gas treatment, chemical industry, metallurgy, papermaking, and form multiple special equipment, such as waste water biochemical treatment equipment, air floatation machine, off-gas cleaning equipment, and the gas-liquid reaction equipment in the field such as chemical industry, pharmacy, metallurgy, food, papermaking etc.
The key of self-suction gas-liquid mixing impeller is blade wheel structure, answers not only that inspiratory capacity is large, gas-liquid mixed is effective, and should prevent from stopping up.The disclosed impellers such as US5091083, US5242600, US3414245 comprise a plurality of hollow blades, qi-emitting hole is arranged on the rear side of blade tip, the vacuum vortex that produces at the blade rear side when it utilizes vane rotary is introduced impeller with air and is released in the water through qi-emitting hole; This impeller low vacuum, inspiratory capacity are little, and without the discharging water ability, only depend on the stirring action of impeller to disperse bubble, and gas-liquid mixed and dispersion effect are poor; Qi-emitting hole on the blade easily stops up, and reason is that water pollutant easily enters the vacuum vortex, and accumulation covers on the steam vent.The disclosed impellers such as US6270061, US4297214, US2246560, US2238139 are comprised of upper and lower cover plate and middle guide vane, and upper cover plate is provided with water inlet, and air intake is positioned at the impeller center; It utilizes the negative pressuren zone air amount that the impeller center produces in the impeller discharging water process, and discharges from periphery after mix with water impeller inside; The problem of this impeller is that inspiratory capacity and the suction water yield exist the contradiction that can not increase simultaneously, the air capacity of impeller rotation or suction can not be excessive, reason is that impeller intake and air inlet all are positioned at the impeller central area, what the impeller center sucked is air-water mixture, along with revolution increases or the air imbibed quantity increasing, air-water mixture density sharply descends, and at center generation air pocket, the vacuum of negative pressuren zone decreases even disappears, and occur fluctuating widely, air imbibed quantity and the suction water yield also reduce thereupon and big ups and downs occur, and equipment is therefore vibration-generating and be in the irregular operation state also.The disclosed impeller such as US1526596, US1374445 is comprised of upper and lower cover plate and middle guide vane, and lower cover is provided with water inlet, and the disclosed impellers such as its air-breathing mechanism and US6270061 are similar, and the air capacity of impeller rotation or suction can not be excessive.The disclosed impellers such as US5358671, US4959183, US4551285, US4668382, US4425232, US2217231 are comprised of upper cover plate and lower blade, this open type impeller also is that the negative pressuren zone that utilizes the impeller center to produce is introduced air, and all there are certain deficiency in air imbibed quantity and mixing wastewater with air effect.US1413723, US1413724, US3917763, US3650513, US3066921, US2996287, US1345596, US1726125, US5160459 etc. are disclosed to be hollow plate-like impeller, its qi-emitting hole (or air duct) is positioned on the periphery or upper and lower cover plate of hollow disc, the main faint centrifugal force of air generation itself and the shear action of impeller surface or periphery and water body of relying on introduced air, gettering ability is little, need under higher revolution, move, and without the liquid sucking-discharging ability, the gas-liquid mixed weak effect.The disclosed impellers such as US5318360, US3070229, US4193949, US382702, formed by upper and lower cover plate and guide vane etc., its qi-emitting hole (or exhaust passage) is positioned on the upper cover plate and lower cover in impeller periphery or the guide vane outside, although impeller has possessed good discharging water ability, but the low vacuum of qi-emitting hole region, the bleed effect is relatively poor.
CN200410050799.1 and CN200610134150.7 disclose several novel air feeding type impellers, at the upper cover plate at hollow disk top and/or the lower cover of bottom guide vane is installed, qi-emitting hole is arranged on the cover plate at place, and be positioned at the rear side of guide vane direction of rotation, its impeller amount of air entrainment is large, and gas-liquid mixed is effective.But because lower cover and upper cover plate limited space, qi-emitting hole quantity and arrangement mode all are restricted, the negative pressure that the current modified line produces between the negative pressure that the guide vane rear side produces in the time of can not taking full advantage of vane rotary and guide vane further improves its amount of air entrainment, to improve its bleed performance.
CN201010514315.X discloses a kind of self-suction gas-liquid mixing impeller, and this impeller is comprised of hollow connecting shaft joint, hollow disc, hollow guide vane, ring diversion plate; The duct of hollow connecting shaft joint communicates with the inner space of hollow disc; Hollow disc is comprised of upper cover plate, lower cover and cylindrical shell; The hollow disc lower cover downside hollow guide vane that is tightly connected, offer the passage that is communicated with hollow guide vane inner space with the lower cover of hollow guide vane correspondence position, hollow guide vane lower end arranges ring diversion plate, and the rear one lateral lobe sheet of hollow guide vane direction of rotation arranges qi-emitting hole.This impeller is owing to adopting by the structure of top hollow disc to hollow guide vane gas distribution, and gas enters hollow guide vane by hollow connecting shaft joint must pass through hollow disc, and the path is longer, is unfavorable for reducing air resistance and strengthens the gas-liquid mixed effect.And the existence of hollow disc has increased the integral thickness of impeller, and impeller liquid when High Rotation Speed is increased its drag, and the energy consumption when being unfavorable for reducing wheel rotation also makes the bad stability under the High Rotation Speed of impeller simultaneously.
