Description
Technical field
The utility model relates to a kind of aerator, especially relates to a kind of self-priming deep water efflux aerator.
Background technology
Along with the progress of society and the raising of people's quality of life, people are also more and more higher to the consciousness of environment protection, environmental purification.But, at present in sewage disposal to the processing of aeration tank, major part all is to adopt to stir oxygenation or adopt oxygen increasing pump oxygenation to handle, manufacturer production compound leaf pulling flow type oxygen increasing pump, eddy current driving aerator etc. are arranged at present, the common drawback that these equipment exist is that the air feed degree of depth is not enough, the air feed deficiency, the dissolved oxygen weak effect; Because electrical equipment is placed in the water or rotating shaft is long, thereby cause short shortcoming in work-ing life.
Summary of the invention
The purpose of this utility model is at above-mentioned shortcoming, provides that a kind of oxygenation effect is good, diffusion area big, the self-priming deep water efflux aerator of long service life.
The utility model is self-priming deep water efflux aerator.For achieving the above object, the utility model has mainly adopted following technical scheme to realize.The utility model is made up of centrifugal sewage pump, and the water inlet pipe of centrifugal sewage pump connects water absorption tube, and water absorption tube is provided with guide shell outward.The rising pipe of centrifugal sewage pump connects jet-pump, and centrifugal sewage pump is provided with heavy bucket outward, and heavy bucket is placed in to be located on the outer float assembly of heavy bucket.Also be provided with case on the float.Described jet-pump is connected at the trunnion of its below, and trunnion connects diffuser tube, and diffuser tube connects the dissolved oxygen pipe, and the dissolved oxygen tube end is provided with pressure dissolved oxygen scatterer, and pressure dissolved oxygen scatterer is provided with some jet pipes, and the end of jet pipe is provided with nozzle.
The utility model compared with prior art has following obvious advantage and actively progressive.(1), the utility model is a kind of self-priming deep water efflux aerator, the sewage that sucks from water absorption tube is through the jet-pump jet, the diffuser tube dissolved oxygen, again by the jet pipe ejection, so this aerator is different with existing aerator, it is to utilize injection stream, entrainment a large amount of air, the synthetic water gas mixture makes fining air bubbles in ejector, send in the deep water again, so have higher oxygen transfer efficiency.(2), the combination of the utility model thrust-augmenting nozzle and pressure dissolved oxygen scatterer, reach the effect of abundant stirring, the thorough mixing of air water stream, collision is pulverized, molten and and radiation as required, reach the dissolved oxygen purpose.(3), long service life.The utility model does not have other moving parts except that motor, pump group, so the complete machine long service life.
The utility model is applicable to sewage disposal.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model structure cut-away view.
Embodiment
As shown in the figure, the utility model is made up of centrifugal sewage pump 4, and the water inlet pipe of centrifugal sewage pump 4 connects water absorption tube 1, the water absorption tube 1 outer guide shell 13 that is provided with.The rising pipe of centrifugal sewage pump 4 connects jet-pump 6, and centrifugal sewage pump 4 is outer to be provided with heavy bucket 2, and heavy bucket 2 is placed in to be located on the outer float assembly 3 of heavy bucket 2.Also be provided with case 5 on the float assembly 3.Described jet-pump 6 is connected at the trunnion 7 of its below, trunnion 7 connects diffuser tube 8, and diffuser tube 8 connects dissolved oxygen pipe 9, and dissolved oxygen pipe 9 ends are provided with pressure dissolved oxygen scatterer 10, pressure dissolved oxygen scatterer 10 is provided with some jet pipes 11, and the end of jet pipe 11 is provided with nozzle 12.
The utility model is applicable to sewage disposal.
