Abstract

The utility model discloses a plate-type micropore aerator, which comprises a base plate, a support body and a diaphragm. The support body is equipped on the base plate and the space between the support body bottom and the base plate forms an air intake chamber. The support body part which is corresponding to the air intake chamber is provided with a plurality of vent holes. The top of the support body is attached with the diaphragm whose end is fixed on the support body. A plurality of micropores are densely distributed on the diaphragm. The utility model has the beneficial effects of effectively preventing blockage and backflow; ensuring the micropores in the silicone rubber diaphragm to be open when aeration is on and be automatically closed when aeration is stopped due to the adopted laser knife mold drilling technology in the diaphragm; and having a good sealing effect owing to the design without a screw between the diaphragm and the support body. The two ends of a hollow sealing tube equipped in the diaphragm are fixed on the support body through the metal wire of the hollow sealing tube. The other two ends of the diaphragm are fixed on the support body through a clamping band.

Description

A kind of board-like micro-hole aerator

Technical field

The utility model relates to a kind of aerating apparatus of disposing of sewage, and particularly relates to a kind of board-like micro-hole aerator that is used for sanitary sewage and biochemical treatment of industrial wastewater.

Background technology

Can at present, when biochemical treatment sewage, provide the dissolved oxygen of foot, be the key that improves biochemical treatment effect and economic benefit.Existing aerator structure is a lot, in using, engineering saved a large amount of energy, and the technical problem that they solve is also dangerous the same, but, existing board-like aerator adopts aeration board to carry out aeration more, as application number is 02267460.8 utility model patent, it discloses a kind of flat micro-hole aerator, comprise that chassis and micro-pore aeration plate two portions constitute, it is characterized in that described aeration board is circular (or rectangle) slab construction, aeration board places on the step on chassis, and and the chassis between the space form inlet chamber, the problem that the aerator of this structure exists is: when stopping aeration, the sewage in the treating pond can take place to flow backwards under the effect of hydraulic pressure and enter aeration board, thus the micropore on the meeting blocking aeration plate.

The utility model content

The purpose of this utility model is to solve the problems of the prior art, but a kind of anti-clogging plug, Visible Counterflow are provided, and the good board-like micro-hole aerator of airtight performance.

The technical solution of the utility model is: a kind of board-like micro-hole aerator, it comprises: chassis, supporter and diaphragm, described supporter is arranged on the described chassis, space between supporter bottom and the chassis forms inlet chamber, the supporter relative with described inlet chamber is provided with a plurality of ventilating pits, described supporter top is covered with described diaphragm, and this diaphragm-operated end is fixed on the described supporter, is densely covered with a plurality of micropores on the described diaphragm.

Preferably, described supporter is the slab structure that vertical section has certain radian, and the lateral length of described supporter is greater than the longitudinal length of supporter.

The two ends that are positioned on the end face of described supporter transversely are respectively equipped with a transverse concave groove, be installed with the hollow sealing pipe on the diaphragm relative with described transverse concave groove, the two ends of described diaphragm arrangement hollow sealing pipe are fixed on the supporter by wire, and the other two ends of described diaphragm-operated are fixed on the supporter by clip.

Preferably, described clip is the clip of stainless steel.

The beneficial effects of the utility model are: effectively anti-clogging plug, Visible Counterflow: diaphragm adopts laser cutting die punching technology, guarantees that the micropore on the silicon rubber diaphragm opens when aeration, auto-closing when stopping aeration; Adopt no screw design between diaphragm and the supporter, obturation effect is good: the two ends that the hollow sealing pipe is set on the diaphragm are fixed by the wire and the supporter that pass the hollow sealing pipe, and the other two ends on the diaphragm are fixed on the supporter by clip.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that A-A among Fig. 1 is to sectional view.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a kind of board-like micro-hole aerator of the utility model, it comprises: chassis 10, supporter 20 and diaphragm 30, described supporter 20 is arranged on the described chassis 10, space between supporter bottom and the chassis forms inlet chamber 40, and the supporter relative with described inlet chamber is provided with a plurality of ventilating pits 21, and described supporter 20 tops are covered with described diaphragm 30, this diaphragm-operated end is fixed on the described supporter, is densely covered with a plurality of micropore (not shown) on the described diaphragm.

The two ends that are positioned on the end face of described supporter 20 transversely are respectively equipped with a transverse concave groove 22, be installed with hollow sealing pipe 31 on the diaphragm 30 relative with described transverse concave groove, the two ends of described diaphragm arrangement hollow sealing pipe are fixed on the supporter by wire, and the other two ends of described diaphragm-operated are fixed on the supporter 20 by clip 50.

Preferably, described clip is the clip of stainless steel.

The chassis linked to each other with the ventage of aeration tube by the folder mouth is installed when the utility model used, and both seal with gasket seal the junction, guarantee the stopping property of ventage, and use novel aerator to be fixed on the aeration tube this with U type anchor ear; During aeration, air is entered in the inlet chamber of aerator by ventage, air is in ventilating pit enters space between supporter and the diaphragm, under gas pressure, diaphragm is heaved slightly, and the micropore that is laid on the diaphragm opens, and air diffuses to the water from micropore, form trickle bubble, thereby realize the function of oxygenation in water; When stopping aeration, air pressure disappears, and diaphragm makes the micropore closure under self elastic effect, and under the hydraulic pressure effect, diaphragm is close on the supporter simultaneously, and the sewage in the aeration tank can not blow back in the supporter, avoids the generation of micropore latch up phenomenon.
