Abstract
The utility model relates to a kind of plug-flow aerators, impeller including being perpendicularly fixed at pool wall, discharge directions along the impeller are equipped with air inlet pipe, bubble cutting is fixed with along inboard wall of tube body in the air inlet pipe, one end of the nearly impeller in the outside of the air inlet pipe is connected by connecting tube with the air blower being set on the water surface circumferentially arranged with air inlet ring, the top of the air inlet ring.The utility model is fed gas into medium using air blower machine, realizes gas-liquid mixed by the negative pressure that impeller plug-flow generates, and cuts to form micro-bubble through multi-layer bubbles cutting bucket.Less equipment both may be implemented in this way and reached enough aeration ranges, while having increased gas-liquid contact time, be conducive to improve aeration efficiency.Open structure avoids sludge blockage, also avoids influence of the liquid level variation to aeration depth.
Description
Technical field
The utility model relates to a kind of plug-flow aerator, especially a kind of branch for minitype vertical type cryogenic liquid tank
Support structure belongs to Design of Mechanical Structure technical field.
Background technique
Aeration is one of the link in sewage treatment, plays important function to the qualified discharge of water quality.It is aerated at present
Mode has bottom micro-pore aeration, mechanical underwater aerator, mechanical surface aerator, rotary-brush type surface aerator etc..It is above-mentioned
Aeration mode has shortcoming, bottom micro-pore aeration, in order to reach aeration service range, it is necessary to be paved with most bottom zone
Domain.For aeration plate once by sludge, silt blocking maintenance is pretty troublesome simultaneously.Bottom micro-pore aeration is general and submersible water impeller cooperates
Using the aeration effect just having had, liquid vertical has been neutralized using the level stream of impeller and has been circulated, increase gas-liquid contact
Time.Mechanical underwater aerator, service range and aeration depth are limited, are aerated low efficiency.Turn brush, plate-spinning etc., is aerated at present
It acts on the depth of water and all there was only 4m or so, be more than this depth, bottom of pond can all have sludgd deposition, while service range is small.
Utility model content
The purpose of this utility model is that: in view of the above-mentioned problems of the prior art, proposing a kind of structurally reasonable, use
Plug-flow aerator that is convenient, can be improved aeration efficiency.
In order to reach the goals above, a kind of plug-flow aerator provided by the utility model, including it is perpendicularly fixed at pool wall
Impeller, the discharge directions along the impeller are equipped with air inlet pipe, and being fixed with bubble along inboard wall of tube body in the air inlet pipe cuts
It cuts, circumferentially arranged with air inlet ring, the top of the air inlet ring passes through connecting tube for one end of the nearly impeller in the outside of the air inlet pipe
It is connected with the air blower being set on the water surface.
Further, the bubble being equipped in the bubble cutting bucket for the air pocket of floating to be cut into minute bubbles is cut
Ailhead.The bubble cutting ailhead is uniformly distributed along the staving inner sidewall circumferencial direction of bubble cutting bucket.
Further, it is equipped in the bubble cutting bucket several for minute bubbles to be cut into the small-sized gas of micro-bubble
Bubble cuts bucket, is evenly equipped with bubble cutting ailhead on the inner wall of each small-sized bubble cutting bucket.
Further, air inlet is evenly arranged on the ring wall of the air inlet ring.
Further, the axis of the axis of the air inlet pipe and the impeller is in the same horizontal line.The air inlet pipe
Both ends have horn mouth.
The utility model has the following beneficial effects: the utility model is fed gas into medium using air blower machine, by pushing away
It flows the negative pressure that device plug-flow generates and realizes gas-liquid mixed, cut to form micro-bubble through multi-layer bubbles cutting bucket.This is practical new simultaneously
The impeller plug-flow distance of type is remote, and service range is wide.Bubble can be pushed to farther away place, both may be implemented so less
Equipment reach enough aeration ranges, while increasing gas-liquid contact time, be conducive to improve aeration efficiency.Open structure
Sludge blockage is avoided, influence of the liquid level variation to aeration depth is also avoided.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is that the bubble of the utility model cuts bucket A-A direction view.
Fig. 3 is the air inlet ring B-B direction view of the utility model.
Detailed description of the invention: 1- impeller, 2- air inlet pipe, 3- annular air inlet ring, 4- bubble cut bucket, and 5- connecting tube connects air blast
Machine, the small-sized bubble of 6- cut bucket, 7- air inlet.
Specific embodiment
A kind of plug-flow aerator provided in this embodiment, as shown in Figure 1 to Figure 3, a kind of plug-flow aerator, including it is vertical
It to be fixed on the impeller 1 of pool wall, is equipped with air inlet pipe 2 along the discharge directions of impeller, the both ends of the air inlet pipe have horn mouth, with
Increase push range.
And it is fixed with bubble cutting bucket 3 along inboard wall of tube body in air inlet pipe, it is equipped in bubble cutting bucket for that will float
Air pocket be cut into minute bubbles bubble cutting ailhead.And bubble cutting ailhead is along the staving inner sidewall circumference of bubble cutting bucket
Direction is uniformly distributed.Meanwhile the uniformity in order to guarantee cutting, it is uniformly equipped in bubble cutting bucket several for will be stingy
Bubble is cut into the small-sized bubble cutting bucket 6 of micro-bubble, is equally evenly equipped with bubble cutting on the inner wall of each small-sized bubble cutting bucket
Ailhead.
One end of the nearly impeller in the outside of air inlet pipe is uniformly set on the ring wall of air inlet ring circumferentially arranged with annular air inlet ring 3
It is equipped with air inlet 7.Meanwhile the top of early air inlet ring is connected by connecting tube with the air blower being set on the water surface.
It when the present embodiment works, is fed gas into medium with air blower machine, the negative pressure generated by impeller plug-flow is real
Existing gas-liquid mixed cuts to form micro-bubble through multi-layer bubbles cutting bucket.The impeller plug-flow distance of the utility model is remote simultaneously,
Service range is wide.Bubble can be pushed to farther away place, and less equipment both may be implemented in this way and reached enough aerations
Range, while increasing gas-liquid contact time, be conducive to improve aeration efficiency.Open structure avoids sludge blockage, also avoids
Influence of the liquid level variation to aeration depth.
In some technological designs, aeration and plug-flow stirring are discontinuity operations.When aerobic reaction, plug-flow and air blower
Group's standard-sized sheet.When detesting hypoxia response, impeller is only opened, guarantees that bottom of pond has certain flow velocity, sludge does not precipitate.For example, SBR technique
Middle anoxic, aerobic discontinuity operation.When hypoxia response, impeller is opened, denitrification is played.When aerobic reaction, unlatching is pushed away
Stream and blast aeration, reach nitrification.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
