As shown in Figs. 1-5, a kind of rotational flow aeration device, including air inlet pipe 1, cylinder 7, deflector 2, eddy flow mechanism 3, cutting Mechanism 4, cylinder cover 5, central axis 6, the air inlet pipe 1 are located at the bottom side of cylinder 7；The deflector 2, eddy flow machine Structure 3, cutting mechanism 4 are located inside cylinder 7；The deflector 2 is hollow centrum 203 wide at the top and narrow at the bottom, and described is hollow Symmetrical vertical plate 201 is set outside centrum 203, diamond block 202 is arranged in interleaved on 203 outer surface of hollow centrum, Also diamond block can be set on hollow centrum according to the actual situation when actual setting, it can be without preliminary cutting；Institute The eddy flow mechanism 3 stated is located at 2 top of deflector, including spiral board 301 and hollow cylinder 1, the hollow cylinder 1 Size is identical as hollow centrum wide end size and is fixed together；The cutting mechanism 4 includes hollow cylinder 2 402 and cutting Block 401, the hollow cylinder 2 402 are connected and fixed with hollow cylinder 1, and the cutting cube 401 is interval-staggered In 2 402 outer surface of hollow cylinder；6 center of central axis opens up through-hole, and the central axis 6 is from hollow centrum 203 Narrow end starts to sequentially pass through deflector 2, eddy flow mechanism 3, cutting mechanism 4 and is tightened in cylinder cover 5 by round nut 504 In；The cylinder cover 5, which is tightened with cylinder 7 by screw thread, to be connect.
As advanced optimizing for the present embodiment, the air inlet pipe includes air inlet end flanges, valve, outlet side；It is described Air inlet end flanges and valve be located on the outside of cylinder, valve is arranged can control intake according to the actual situation；The outlet side In cylinder and gas outlet direction is upward, and the outlet side is taper, and narrow end upper, prolong from cylindricality by pressure-air outlet side Taper is extended to, fill-before-fire goes out after compressing pressure-air in pipe, is more likely formed injection stream.
Lower area in the injection stream region that pressure-air is formed forms negative pressure of vacuum, and the sewage of aerator lower part is strong It is sufficiently mixed after power sucking in inlet zone, subsequently into the conical flow guiding area of deflector, gas-liquid mixed is in conical flow guiding area Further release and it is preliminary air bubble is cut after, into eddy flow area.
As advanced optimizing for the present embodiment, hollow centrum bottom the going out apart from air inlet pipe of the deflector Gas end distance is 5mm, and 5mm is arranged according to the size of aerator and length, the interior sewage quantity by vacuum suck of this distance and Degree of mixing with air is best.
As advanced optimizing for the present embodiment, narrow upper width under the vertical plate of the deflector is hollow centrum Setting principle is the same, and one is the rear water conservancy diversion that is sufficiently mixed of gas-liquid mixed, and two is adapt to the compressed release stream of pressure-air, so that Release stream is preferably mixed with the sewage stream of sucking.
As advanced optimizing for the present embodiment, part of the diamond block under is triangle, and triangle can be more Good cuts to towards the bubble flowed up.
As advanced optimizing for the present embodiment, the vertical deflector of the deflector and the spiral board of eddy flow mechanism It is arranged for the even number of 4`8 block, is symmetrical arranged more favorably with the shunting of gas-liquid mixed stream and water conservancy diversion, quantity setting can be according to aeration need Aerator size of summing setting.
As advanced optimizing for the present embodiment, the cutting cube of the cutting mechanism is spaced in space from top to bottom Interlaced arrangement, and to cut the eddy flow of fast intermediate channel formation from top to bottom, the eddy flow that this eddy flow and eddy flow mechanism are formed Direction is different, i.e., the eddy flow formed in eddy flow mechanism is entering the change of cutting mechanism rear direction, into another eddy flow direction, makes Obtain mixed liquor more fully collisional mixing and cutting.
As advanced optimizing for the present embodiment, the cutting cube of the cutting mechanism is the inverted triangle structure of strip, Downward, strip setting can cut more gas-liquid mixed streams, and triangular configuration is similar to stage property at triangle row tip Be arranged more favorably with the cutting and subdivision to bubble.
As advanced optimizing for the present embodiment, the hollow cylinder two of the cutting mechanism is several pieces of compositions or is one Monolith is horizontally disposed with a circle cutting cube on every piece of hollow cylinder, when being set as several pieces of compositions, is conducive to more shield aerator Length sets the quantity of needs, and a kind of aerator of length can only be adapted to when a monolith.
After aerator is installed on aeration tank, it is passed through pressure-air, the opening degree that gas valve is set as needed is big It is small, after high pressure air flow enters air inlet pipe, ejected after taper outlet side is further compressed again, the sewage with sucking Be sufficiently mixed in inlet zone, when into guiding region when mixing water conservancy diversion and by conical flow guiding area it is preliminary cut after, enter Eddy flow area forms eddy flow, then into cutting region；In the staggeredly spaced apart inverted triangle block that cutting region is arranged to mixed Interflow carries out cutting again, and changes due to cutting another swirl channel that the space structure arranged fastly is formed from eddy flow The direction of the mixing eddy flow come in mechanism is collided so that mixing eddy flow constantly mixes again, cutting, so that bubble is increasingly It is small, and finally ejected on aerator top；Due to the negative pressure of vacuum of aerator bottom end, the mixed flow ejected may make again It recycles and carries out into aeration process, increase residence time of the micro-bubble in sewage, improve the utilization rate of oxygen, make to be charged into Pressure-air and cesspool in sludge impurity etc. reach best admixture and longest residence time so that the dirt in sewage Mud impurity aerobic treatment carries out abundant, and in the whole process without sludgd deposition, no blocking, low energy consumption, non-maintaining.
Above-mentioned specific embodiment is only the specific case of the utility model, and the scope of patent protection of the utility model includes But it is not limited to the product form and style of above-mentioned specific embodiment, it is any to meet the utility model claims book and any institute Belong to the appropriate changes or modifications that the those of ordinary skill of technical field does it, should all fall into the patent protection of the utility model Range.
