Abstract

The utility model relates to an air valve core type aerator, which comprises a framework and a casing tube. The framework is the communicating structure of a single hollow tube, or a plurality of hollow tubes. One end of each of the hollow tube is closed. A plurality of small air outlet holes are arranged on the hollow tube. The casing tube is an elastic rubber casing tube, and is sheathed on the hollow tube to cover the small air outlet holes. One end head of the framework is an opening joint, and is provided with a thread buckle. The utility model has novel conceiving, reasonable design, simple structure, low cost and price, high oxygen filling efficiency, uniform air distribution, no blocking, good adaptability, and excellent technical performance.

Description

Valve inside formula aerator

Technical field:

The utility model relates to a kind of water treating equipment, is specifically related to a kind of valve inside formula aerator in the large-scale aeration in sewage treatment equipment.

Background technology:

In the sewage biochemical treatment system, in the particularly large-scale Sewage treatment systems, aerator current consumption accounts for the 60-70% of entire sewage treatment plant electricity consumption, so the efficient of aerator directly affects wastewater treatment efficiency and construction investment and working cost.In the eighties mid-term, China begins to develop micro-hole aerator, and as ceramic capillary aerator, rubber micro-hole aerator etc., but the eyelet of this class aerator stops up easily, very strict to dedusting, grease proofing, antirust etc. requirement, thus promoting the use of of micro-hole aerator influenced.

Summary of the invention:

Technical problem to be solved in the utility model is: solve existing micro-hole aerator eyelet stop up easily, to dedusting, grease proofing, antirust strict, problem that operational failure is many, and provide a kind of oxygenation capacity good, do not need air filtration, simple in structure, be difficult for obstruction, safe ready, cheap valve inside formula aerator.

The technical solution adopted in the utility model is: this valve inside formula aerator comprises skeleton and sleeve pipe, skeleton is single open tube or many open tube connectivity structures, the sealing of open tube one end, have some apertures of giving vent to anger on the open tube, sleeve pipe is a flexible casing, be enclosed within on the open tube, and cover the aperture of giving vent to anger, a termination of skeleton is an open joint.

In the technique scheme, the open joint of skeleton is threaded screw thread, connects in order to be screwed on the air feed main.

In the technique scheme, have outwards outstanding bulge loop on the open tube, casing pipe sleeve is on open tube and cover bulge loop.

In the technique scheme, also have on the skeleton with skeleton for being connected the nut circle of integral body, during installation, convenient wrench is clamped the nut circle and is tightened, simultaneously, this nut circle is again the positioning retainer ring of casing pipe sleeve when going into skeleton.

Valve inside formula aerator of the present utility model tightened open joint by the screw thread screw thread be fixed on the air main conduit, air enters in the valve inside formula aerator from main conduit, and flow out from the aperture of giving vent to anger of skeleton, enter the gap between skeleton and the sleeve pipe, under the air pressure effect, casing expandable, gap between skeleton and sleeve pipe flows into the water, the diameter of bubble and hydraulic pressure, air pressure and telescopic elasticity are relevant, when the difference of air pressure and hydraulic pressure sum hour, bubble is just little, otherwise bubble is just big, when the air major trunk roads stop air feed, the aperture of giving vent to anger on the skeleton enters aerator and air line just by bobbin seal to prevent sewage.

The utlity model has following outstanding feature:

(1) the aerator oxygen-transfer efficiency can meet or exceed the oxygen-transfer efficiency of existing micro-hole aerator;

(2) air does not need particular filter, no latch up phenomenon;

(3) air distribution is even, and the size of exhaust clearance changes with the variation of aeration rate;

(4) simple in structure, cost is cheap, and is easy for installation, is fit to China's national situation, and technical feature is good.
