Description
Technical field:
The invention belongs to sewage aerobic and process equipment technical field, relate to one enclosed pump-type impeller air-breathing aerator under water, it is possible to suitable in various middle-size and small-size Sewage Disposals, it is achieved oxygenic aeration, and play mix and blend effect.
Background technology:
The biological treatment of waste water, refer to the metabolism by microorganism, an organic part in waste water is converted into the cellular material of microorganism, another part is converted into the method for more stable chemical substance (inorganic matter or simple organic), bioremediation more common at present includes Aerobic Process for Treatment and anaerobic treatment, owing to Aerobic Process for Treatment is when providing free oxygen, the biochemical action utilizing aerobe realizes degradation treatment, there is the advantages such as response speed is fast, required time is short, course of reaction health, and widely used.In Aerobic, aeration mode has a variety of: be broadly divided into blast aeration, surface aeration, under water aeration and the big class of oxygen aeration four, blast aeration is the compression air provided by air pressurized equipment, sent on the air-diffuser in Aeration tank by tubing, spread in the form of bubbles；Surface aeration is to produce hydraulic jump when water surface rotates by aerator, and a large amount of water droplets and sheet-like water shield are thrown in the air, and water and air are fully contacted, and make oxygen quickly incorporate water body；While oxygenation, under the plug-flow effect that aerator rotates, water body few for pond bottom oxygen content is promoted upwards circulation, continuous oxygenation；Aeration is to be filled with air at water bottom or middle level under water, full and uniform with water body mixes, and completes oxygen transfer from gas phase to liquid phase；The aerator used is also of a great variety; and the quality of aerator; not only affect biochemical wastewater treatment effect; and directly influence Treatment stations and take up an area, invest and operating cost; therefore in recent decades, it is always up an important scientific research task of various countries' common concern, after entering the eighties; due to energy crisis, reach the improvement of aerator of 60-80% and the development of novel device more becomes the problem that various countries are badly in need of solving to accounting for sewage farm operating cost.
At present both at home and abroad conventional aerator classification is a lot, domestic is divided into by the mode of supply traditionally: blast aeration oxygenation, surface aeration oxygenation and aeration aerating three major types under water, blast aeration noise of equipment is relatively big, easily affects surrounding enviroment, and adjustability is poor；The pump-type impeller aerator of surface aeration equipment vertical shaft type, inversed umbrella type impeller surface aeration machine, K type impeller surface aeration machine, plate impeller surface aeration machine etc., the rotating brush type aerator of horizontal axial type, turnplate aerator etc., in aeration process, some sewage can produce a large amount of foam, this foam can hinder Aeration tank liquid level oxygen uptake, make dissolved oxygen efficiency sharply decline, cause treatment effeciency to be substantially reduced；Failure of underwater aeration equipment has Self-priming jet aeration machine, Gas feeding jet aerator, self-priming spiral aerator and pump type aerator etc., wherein jet-flow aeration power consumption is relatively big, high directivity, and self-priming spiral aerator and pump type aerator motor sealing property under water are high, difficult in maintenance；nullAdditionally there are the aeration turn plate of a kind of improvement disclosed in Chinese patent 03135082.8 and vertical-flow aeration oxygen increasing machine，The disclosed a kind of straight vane aerator of Chinese patent 200510055350.9，The disclosed a kind of aerator of Chinese patent 2010102087232，The disclosed a kind of diving of Chinese patent 201410227178.X advances aerator，And one stirs aerator etc. under water disclosed in Chinese patent 2014102271065，All kinds of aerators or structure disclosed in above-mentioned technology are complicated、It is difficult to installation and maintenance，Or oxidation effect is not good enough、Easily deposit blocking，Or power consumption is high、Noise is big，All can not well realize circulation oxygenation，Therefore，A kind of novel pump-type impeller air-breathing aerator of enclosed under water of research design，To adapt to different aeration demands，Have a good application prospect and practical value.
Summary of the invention:
It is an object of the invention to the shortcoming overcoming prior art to exist, seeking design provides one enclosed pump-type impeller air-breathing aerator under water, it is possible to coordinate the processing unit of various ways, it is achieved the aeration effect that energy consumption is low, oxygenation is sufficient.
To achieve these goals, the pump-type impeller air-breathing aerator agent structure of enclosed under water that the present invention relates to includes motor, shaft coupling, support, shaft, bearing, air inlet disk, water gap, double shrouded wheel, air inlet pipe, fixing bolt, first square position, guiding trestle, adjust bolt and the second square position, the pedestal upper end of frame structure and centre are fixed with the first square position and the second square position respectively, first square position is fixedly installed motor by fixing bolt, the lower end of motor is connected to shaft by shaft coupling transmission formula, air inlet disk is arranged on the lower section of the second square position by adjusting bolt, the side of air inlet disk has been docked and connected air inlet pipe, air inlet pipe is by being embedded the through installation of guiding trestle on the first square position and the second square position；Bearing is through to be embedded in the second square position central authorities, and the lower end of shaft is connected to double shrouded wheel by driven type after the through air inlet disk of bearing, forms the adjustable water gap of size between double shrouded wheel and air inlet disk；Motor drives shaft to drive double shrouded wheel to rotate by bearing and forms negative pressure, under air inlet disk and double shrouded wheel interact, the negative pressure formed is aspirated air by the air inlet pipe of air inlet disk and aspirates muddy water by water gap, air and muddy water stir at double shrouded wheel and form molten gas effect and throw away double shrouded wheel under immixture, expand to formation aeration in water body.
Compared with prior art, the water gap size between air inlet disk and double shrouded wheel is adjustable for the present invention, can not only adapt to the aeration degree of depth needed for different water depth, and the different vacuums formed can adjust tolerance；Single unit system only has motor and air entry more than water body liquid level, and noise is less, and double shrouded wheel faces water body directly will not form high pressure compressing to mud, and gas-vapor mix process carries out being capable of natural cooling in water body；Air inlet pipe and air inlet disk up/down perforation, do not result in the blocking into water precipitation；Activated sludge process can be applicable to, be thoroughly mixed the processing unit of the various ways such as Aeration tank；Its apparatus structure is simple, and reasonable in design, principle is reliable, it is simple to maintenance and installation, and tolerance is adjustable, and noise is little, low in energy consumption, and oxygenation capacity is strong, and aeration effect is good, applied widely, uses environmental friendliness.
