Abstract
The utility model provides a tearing-resistant and thread-off-preventing aerator, which belongs to the technical field of water treatment equipment and comprises a bearing plate and a microporous rubber diaphragm wrapped and covered on the bearing plate, wherein an arched limiting device is placed above the microporous rubber diaphragm and is fixed on the side surface of the bearing plate; and a design interval is reserved between the arched limiting device and the microporous rubber diaphragm. The aerator has a simple structure and has tearing-resistant performance and thread-off-preventing performance, and if the air pressure exceeds a normal value when the aerator is used, the rubber diaphragm of the aerator cannot be expanded or stretched abnormally.
Description
Technical field
The utility model is to the improvement of water treatment with the rubber diaphragm micro-hole aerator, belongs to the water treating equipment technical field.
Background technology
Aerating system is an important integral part in the water treatment, in sewage aerobic is handled, making by aeration has an amount of oxygen in the water, can keep survival of aerobic flora and effectively work in the water treatment, so oxygen level is a very important parameter, the rubber diaphragm micro-hole aerator, can produce very fine and closely woven bubble, effectively increase the area that bubble contacts with water, greatly improve the efficient of dissolved oxygen, therefore in modern water treating equipment, be widely used.
The rubber diaphragm micro-hole aerator has gland usually, the mipor rubber diaphragm, and supporting plate, shell is formed.When aeration not, external water pressure entirely is pressed in rubber diaphragm on the supporting plate, micropore on the rubber diaphragm is owing to the elastic shrinkage of rubber is closed, prevent sewage backflow, enter aerated conduit inside, air is heaved rubber diaphragm when aeration, micropore on the rubber diaphragm is opened, make inner air by the micropore on the rubber diaphragm, be discharged in the water, realize process to Aeration in the water in fine and closely woven bubble mode.But owing to reasons such as other parts aerator obstructions in air pressure fluctuation, the sewage lagoon sometimes, when causing air pressure to surpass normal value, the aerator rubber diaphragm is expanded stretching unusually, makes rubber diaphragm tear or come off, whole aerating system cisco unity malfunction causes bigger financial loss.
Summary of the invention
The utility model provides a kind of anti-tear anticreep aerator just in order to overcome above-mentioned deficiency, and main innovation is to adopt stop means at rubber diaphragm, prevents the unusual expansion of diaphragm and damages.It specifically is to implement like this: anti-tear anticreep aerator, comprise supporting plate, the mipor rubber diaphragm of Bao Meng on supporting plate, it is characterized in that mipor rubber diaphragm top is equipped with the arch stop means, described arch stop means is fixed on the side of supporting plate, leaves design pitch between arch stop means and mipor rubber diaphragm.
This arch stop means is made of the grizzly bar/aperture plate more than one or, is parallel between grizzly bar/aperture plate or is staggered, and structure is that the arch stop means is that grizzly bar/aperture plate collection more than one meets at the cover body of any preferably.
It is good that the quantity that constitutes the grizzly bar/aperture plate plow stop means is generally the 1-6 bar.
The arch stop means also can be designed to other structure, for example mesh structure.
When aerator was not worked, external water pressure entirely was pressed in rubber diaphragm on the supporting plate, and the micropore on the rubber diaphragm prevents sewage backflow because the elastic shrinkage of rubber is closed.During the aerator works better, air is heaved rubber diaphragm, and rubber diaphragm is heaved the position and seen accompanying drawing 3, and the micropore on the rubber diaphragm is opened, and makes inner air by the micropore on the rubber diaphragm, is discharged in the water in fine and closely woven bubble mode, realizes the process to Aeration in the water.When the aerating pipelines pressure abnormity raise, air continued rubber diaphragm is heaved, and reaches the position of arch stop means, see accompanying drawing 4, under the effect of arch stop means, limited further heaving of rubber diaphragm, thereby prevented rubber diaphragm from drawing high unusually and produce the situation of tearing, coming off.Air pressure recover normal after, diaphragm is returned to the normal position under the effect of the elastic shrinkage of rubber and hydraulic pressure.
The utility model is simple in structure, when if air pressure surpasses normal value, the aerator rubber diaphragm of this device can not expanded stretching unusually, has anti tear, anticreep performance in the use.

Embodiment
When diaphragm was worked at normal barometric pressure, the arch stop means of diaphragm and diaphragm top separated, and has only when air pressure surpasses normal value, and diaphragm just contacts with the arch stop means.
Embodiment 4, reference example 1, and encircleing into stop means is mesh structure.
Embodiment 5, reference example 1, and encircleing into stop means is that 1 grizzly bar or aperture plate are formed.
Claims (5)
1. anti-tear anticreep aerator, comprise supporting plate, the mipor rubber diaphragm of Bao Meng on supporting plate is characterized in that mipor rubber diaphragm top is equipped with the arch stop means, described arch stop means is fixed on the side of supporting plate, leaves design pitch between arch stop means and mipor rubber diaphragm.
2. anti-tear anticreep aerator according to claim 1 is characterized in that the arch stop means is made of the grizzly bar/aperture plate more than one or, is parallel between grizzly bar/aperture plate or is staggered.
