Abstract
The utility model relates to dynamic aeration equipment, which is provided with a barrel body in which a small ball is arranged, and the upper part of the barrel body is matched with grid. The lower part of the barrel body is provided with an air inlet passage and an air distributing disc, the upper part of the air distributing disc is provided with a rubber cutting disc and a hard cutting disc, a spring is cushioned between two cutting discs, in addition, a wall of the barrel body is provided with 4-8 small holes. Thereby, the utility model has simple structure, high aeration efficiency, corrosion resistance, convenient installation, convenient use, low cost, etc. Particularly, the utility model can solve the problem of mud blockage fundamentally.
Description
The utility model relates to and a kind of sewage is carried out the aerator that biochemical treatment is used, need the oxygenation place that sewage is carried out the aerator that biochemical treatment is used in particular for contact-oxidation pool, active sludge aeration tank etc.
Along with the development of environmental protection cause, China environment protection as a fundamental state policy, sewage disposal is subject to people's attention day by day.Biological process is still a kind of effective ways of sewage disposal in the present sewage treatment project, biological sewage is handled the utilization aeration aerating component part that then is absolutely necessary, so the quality of aerator just directly has influence on the effect of sewage biochemical treatment but also directly has influence on treating pond occupation of land, investment and working cost.Domestic in recent years novel aerator is succeeded in developing in succession, as the fixing spiral aerator of single passage, two channels and triple channel, air diffusion aerator, middle micro-hole aerator etc.These aerators all belong to static type, though advantage is respectively arranged, what also have is individual higher, take up an area of the pond and hold greatlyyer, and what have also need dispose deficiency such as back flushing utility appliance, especially all unresolved to the sludge blockage problem.
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of dynamic aeration device that fundamentally solves the sludge blockage problem is provided.
The purpose of this utility model is finished by following technical solution, it has a cylindrical shell, in bead is housed, the top of cylindrical shell disposes grid, the bottom of cylindrical shell is provided with induction trunk and air distribution plate, and the upper unit of air distribution plate has the rubber chopping disk in cylindrical shell.
The periphery of described rubber chopping disk is the periphery of band slot shape.
The utility model is connected to the hard chopping disk of band peripheral teeth on the top of rubber chopping disk with roller, and is equipped with spring between hard chopping disk and the rubber chopping disk.
The utility model is also on the cylindrical shell, offer a uniform 4-8 aperture on the barrel of contiguous rubber chopping disk.
Accompanying drawing is a structural representation of the present utility model.
To be described in detail the utility model by accompanying drawing below: aeration cylindrical shell 1 is equipped with several beads 2 by ABC or polypropylene injection moulding in it.The top of cylindrical shell 1 disposes grid 3, and grid 3 is fixed on the cylindrical shell 1 with double-screw bolt 4 at periphery.The bottom of cylindrical shell 1 is provided with induction trunk 5 and air distribution plate 6, device has rubber chopping disk 7 in the top of air distribution plate 6, cylindrical shell 1, these rubber chopping disk 7 reason elastomeric materials are made flexible, and its periphery is set to the slot shape, thereby to playing good action of turbulent flow through its peripheral air water mixed flow.Top at rubber chopping disk 7 is socketed with the hard chopping disk 9 of band peripheral teeth with pin 8, and is equipped with spring 10 between hard chopping disk 9 and rubber chopping disk 7, makes hard chopping disk 9 can produce oscillation action after the impact that is subjected to gas-vapor mix stream.The utility model also is close to two chopping disks and offers 4-8 aperture 11 on the perisporium of cylindrical shell 1, these apertures enter in the cylindrical shell from induction trunk 5 at airflow, will flow in the cylindrical shell 1 from aperture by the external current of guide barrel, increase the mixing of air water in the cylindrical shell, thereby increase the oxygen level in the water in the cylindrical shell.Air is entered by the bottom inflow passage 5 of aeration cylindrical shell 1, divide to walk triple channel, through stopping of air distribution plate 6 top rubber chopping disks 7, be cut from its peripheral air cleft behind the air-flow extrusion chopping disk, in cutting process, because of chopping disk 7 is made certain elasticity by rubber, thereby air-flow is trembleed during chopping disk 7 and is increased the effect of the plain stream of cutting in extruding.Air-flow runs into stopping of hard chopping disk 9 again after rubber chopping disk 7 is gushed out, the chopping disk 9 of extruding once more, under the effect of spring 10, air-flow extrusion chopping disk 9 can produce vibration, increased agitaion with water, and cut for the second time from peripheral slot once more, afterwards under the turning effort of air-flow bead 2 in cylindrical shell 1, constantly increase turbulent effect, the mutual bump of bead 2 will make bubble cut apart more tinyly simultaneously, strengthened the transfer function of oxygen, improved the utilization ratio of oxygen, the oxygen level in the water is further improved.In addition, the utility model is because after being provided with 4-8 the aperture on the barrel, when inflation work, airflow can drive the outer water of cylindrical shell and flow into cylindrical shell in aperture, make aqueous vapor fully exchange contact with activation, fully gas is dissolved in the water, and has improved the content of oxygen in water once more.The utility model is in when operation, also because of motion that bead is arranged with stop, leaning on the floating formed tectum of bead 2, makes that mud is unlikely to be deposited on air distribution plate and two chopping disks, so sludge blockage can not take place.
The utility model compared with prior art, have simple in structure, the oxygen-transfer efficiency height, corrosion-resistant, install Easy to use, the characteristics such as with low cost are a kind of good dresses that can fundamentally solve this problem of sludge blockage Put.
