Abstract
An umbrella flow cutting type aerator comprises an aeration head, an air inlet pipe and an air outlet pipe, wherein the aeration head is shaped like a cone, a plurality of sawteeth are distributed on the outer wall of the aeration head, and a tooth top of each sawtooth is towards a cone-shaped apex angle. The air inlet pipe is sleeved inside the air outlet pipe and the axial direction of the air inlet pipe and the axial direction of the air outlet pipe are the same. One end of the air inlet pipe is sealed, the side wall of the air inlet pipe close to the sealed end is provided with a plurality of aeration holes, and a cavity between the air inlet pipe and the air outlet pipe is communicated with an inner cavity of the air inlet pipe through the aeration holes. The cone-shaped apex angle of the aeration head is connected with the sealed end of the air inlet pipe. One end of the air outlet pipe is sealed, the sealed end of the air outlet pipe is towards the same direction with the opening end of the air inlet pipe, and the opening end of the air outlet pipe is towards the cone-shaped apex angle of the aeration head. Compared with the prior art, the umbrella flow cutting type aerator has the advantages of being corrosion resistant, high in the oxygen utilization rate, not easy to block, convenient to install, and the like.
Description
Technical field
The utility model relates to the technical field of sewage biochemical processing process, particularly a kind of aerator that dissolved oxygen is provided.
Background technology
At petrochemical industry, printing and dyeing, weaving, food, brewage, in the industrial sewage such as pharmacy, papermaking and the city domestic sewage biochemical processing process, aerator is owing to can provide the required dissolved oxygen of biochemical water treatment and widespread use.At present, the problem that exists of common aerator mainly be easily be corroded, coefficient of oxygen utilization is low, easily blocked and inconvenience etc. is installed.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of new umbrella stream cutting type aerator, concrete technical scheme is as follows:
A kind of umbrella stream cutting type aerator comprises air distribution head, inlet pipe and escape pipe; The profile of described air distribution head is taper, and at the outer wall of taper air distribution head a plurality of sawtooth that distributing, the crown of each sawtooth is towards conical apex angle; Described inlet pipe is enclosed within the escape pipe, and the two is axially identical; One end of inlet pipe seals, and has a plurality of qi-emitting holes at the sidewall of the close blind end of inlet pipe, and inlet pipe is communicated with the inner chamber of inlet pipe by qi-emitting hole with cavity between the escape pipe; The conical apex angle part of described air distribution head is connected with the blind end of inlet pipe; One end of described escape pipe seals, and the blind end of escape pipe and the opening end of inlet pipe are towards identical; The opening end of escape pipe is towards the conical apex angle of air distribution head.
Be provided with a plurality of rotating plates in the described inlet pipe, each revolve pull axially and inlet pipe axially identical.
The blind end of described escape pipe has a plurality of mudholes.
Described each sawtooth divides multilayer, and each layer sawtooth is distributed on the outer wall of taper air distribution head from top to bottom.
Described each qi-emitting hole is arranged around the air inlet tube wall.
