Description

One is enclosed pump-type impeller air-breathing aerator under water

Technical field:

The utility model belongs to sewage aerobic treatment facility technical field, relates to one enclosed pump-type impeller air-breathing aerator under water, can be applicable to various middle-size and small-size sewage works, realize 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 microbial cell material, another part is converted into the method for more stable chemical substance (inorganics or simple organic), bioremediation comparatively conventional at present comprises aerobic treatment and anaerobic treatment, because aerobic treatment is under the condition providing free oxygen, the biochemical action of aerobe is utilized to realize degradation treatment, there is the advantages such as speed of response is fast, required time is short, reaction process health, and widely used.In Aerobic, aeration mode has a variety of: be broadly divided into the large class of blast aeration, surface aeration, under water aeration and oxygen aeration four, blast aeration is the pressurized air provided by air pressurized equipment, sent on the air-diffuser in aeration tank by tubing system, spread in the form of bubbles; Surface aeration produces hydraulic jump by aerator when water surface rotates, and a large amount of water droplet and sheet-like water shield are thrown in the air, and water fully contacts with air, makes oxygen incorporate water body very soon; While oxygenation, under the plug-flow effect that aerator rotates, water body few for pond bottom oxygen level is promoted upwards circulation, continuous oxygenation; Aeration is filled with air at water bottom or middle level under water, mixes with water body is full and uniform, completes the transfer of oxygen 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 have influence on Treatment stations occupation of land, investment and working cost; therefore in recent decades, it is the important scientific research task that various countries are concerned about jointly always, after entering the eighties; due to energy dilemma, the development accounting for improvement and novel appts that sewage farm working cost reaches the aerator of 60-80% is more become to the problem being badly in need of solving in various countries.

At present both at home and abroad conventional aerator classification is a lot, is domesticly divided into by the mode of air feed traditionally: blast aeration oxygenation, surface aeration oxygenation and aeration aerating three major types under water, and blast aeration noise of equipment is comparatively large, easily affect surrounding enviroment, and adjustability is poor, the pump-type impeller aerator, inversed umbrella type impeller surface aeration machine, K type impeller surface aeration machine, plate impeller surface aeration machine etc. of surface aeration equipment vertical shaft type, the rotating brush type aerator, turnplate aerator etc. of horizontal axial type, in aeration process, some sewage can produce a large amount of foam, this foam can hinder aeration tank liquid level oxygen uptake, dissolved oxygen efficiency is sharply declined, causes processing efficiency greatly to reduce, 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 comparatively large, the high directivity of jet-flow aeration power consumption, sealing property is high, difficult in maintenance under water for self-priming spiral aerator and pump type aerator motor, there are the aeration turn plate of a kind of improvement disclosed in Chinese patent 03135082.8 and vertical-flow aeration oxygen increasing machine in addition, a kind of straight vane aerator disclosed in Chinese patent 200510055350.9, a kind of aerator disclosed in 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 aerator or complex structure disclosed in above-mentioned technology, be difficult to installation and maintenance, or oxidation effect is not good enough, easy alluvial blocking, or power consumption is high, noise is large, all can not well realize circulation oxygenation, therefore, a kind of novel pump-type of enclosed under water impeller air-breathing aerator of research and design, to adapt to different aeration demands, have a good application prospect and practical value.

Summary of the invention:

The purpose of this utility model is the shortcoming overcoming prior art existence, seeks design and provides one enclosed pump-type impeller air-breathing aerator under water, can coordinate the processing unit of various ways, realize the aeration effect that energy consumption is low, oxygenation is sufficient.

To achieve these goals, the pump-type of the enclosed under water impeller air-breathing aerator agent structure that the utility model relates to comprises motor, shaft coupling, support, stir shaft, bearing, air inlet disk, water gap, trash-type impeller, inlet pipe, standing bolt, first square position, guiding trestle, adjustment bolt and the second square position, the pedestal upper end of skeleton construction and centre are fixed with the first square position and the second square position respectively, first square position is fixedly installed motor by standing bolt, the lower end of motor is connected with stir shaft by shaft coupling transmission formula, air inlet disk is arranged on the below of the second square position by adjustment bolt, the side of air inlet disk has been docked and connected inlet pipe, 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 stir shaft is connected with trash-type impeller by driven type after the through air inlet disk of bearing, forms the water gap that size is adjustable between trash-type impeller and air inlet disk, motor drives stir shaft to drive trash-type impeller to rotate by bearing and forms negative pressure, under air inlet disk and trash-type impeller interact, the negative pressure formed is by the inlet pipe suction air of air inlet disk and aspirate muddy water by water gap, air and muddy water form molten gas effect and throw away trash-type impeller under trash-type impeller is uniformly mixed effect, expand in water body and form aeration.

Compared with prior art, the water gap size between air inlet disk and trash-type impeller is adjustable for the utility model, can not only adapt to the aeration degree of depth needed for different water depth, and the different vacuum tightnesss formed can adjust tolerance; Single unit system only has motor and suction opening more than water body liquid level, and noise is less, and trash-type impeller faces water body directly can not form high pressure compressing to mud, and gas-vapor mix process carries out realizing naturally cooling in water body; Inlet pipe and air inlet disk up/down perforation, can not cause the blocking into water precipitation; The processing unit of the various ways such as activated sludge process, completely mixed aeration pond can be applicable to; Its apparatus structure is simple, reasonable in design, and principle is reliable, and be convenient to maintenance and installation, tolerance is adjustable, and noise is little, low in energy consumption, and oxygenation capacity is strong, and aeration is effective, applied widely, and environment for use is friendly.
