Abstract
A kind of Novel disc-type aerator, including support plate, non-return bolt, non-return gasket and rubber diaphragm；Inlet channel is provided on the inside of the support plate, the outlet side of inlet channel is provided with venthole, the non-return bolt is provided in the outlet nose end of support plate, the non-return gasket is provided in the lateral surface of non-return bolt, the rubber diaphragm is provided in the upper surface of support plate.The beneficial effects of the utility model are：Non-return bolt is provided in the venthole of the plate-type aerator, prevent thering is a small amount of sewage to be back under the action of hydraulic pressure at fenestra in aerating system pipeline after aerator is closed, so as to avoid the occurrence of the risk that aerating system is blocked by deposition, the aeration efficiency and service life of aerator are improved.
Description
Technical field
The utility model is related to a kind of aerator more particularly to a kind of plate-type aerators for being provided with check-valves.
Background technology
Plate-type aerator is the latest model aerator developed the eighties, and the device aeration bubbles diameter is small, gas-liquid interface
Diameter is small, and gas-oil interfaces are big, and bubble diffusion is uniform, and corrosion resistance is strong, is current sewage treatment plant's two stage biological processing therefore
Stage common equipment, air blower is by air by pipeline to aeration tank bottom, and micropore on plate-type aerator diaphragm is by sky
Qi leel is cut into minute bubbles and is diffused into sewage, so that aerobic microbiological absorbs oxygen in bubble in sewage, and then treated sewage,
Reduce the organic pollution in sewage.
But for specific sewage treatment process, aerating system needs intermittent duty, some stage parts aerating system
It needs to close, there is a small amount of sewage to be back under the action of hydraulic pressure at fenestra in aerating system pipeline after shutdown, it is long
The easy deposition of aerating system blocks after phase operation, therefore, for the defect, it is necessary to effectively be innovated to existing technology.
Utility model content
For disadvantages described above, the purpose of this utility model is to provide a kind of Novel disc-type aerator, the plate-type aerators
Venthole in be provided with non-return bolt, prevent aerator close after have a small amount of sewage under the action of hydraulic pressure from fenestra
Place is back in aerating system pipeline, so as to avoid the occurrence of the risk that aerating system is blocked by deposition, improves the exposure of aerator
Gas efficiency and service life.
To achieve the above object, the utility model uses following technical scheme：
A kind of Novel disc-type aerator, including support plate, non-return bolt, non-return gasket and rubber diaphragm；The branch
Inlet channel is provided on the inside of support plate, the outlet side of inlet channel is provided with venthole, is set in the outlet nose end of support plate
There is the non-return bolt, the non-return gasket is provided in the lateral surface of non-return bolt, set in the upper surface of support plate
There is the rubber diaphragm；
It is fixed correspondingly, non-return gasket only carries out part, makes it that can be started under a gas flow and be aerated.
The beneficial effects of the utility model are：
Non-return bolt is provided in the venthole of the plate-type aerator, prevents there is a small amount of sewage after aerator is closed
It is back under the action of hydraulic pressure at fenestra in aerating system pipeline, so as to avoid the occurrence of the wind that aerating system is blocked by deposition
Danger improves the aeration efficiency and service life of aerator.
Description of the drawings
The utility model is described in further detail below according to attached drawing.
Fig. 1 is the side, sectional structure diagram of the utility model；
In figure：
1st, support plate；2nd, inlet channel；3rd, non-return bolt；4th, non-return gasket；5th, rubber diaphragm.
Specific embodiment
A kind of Novel disc-type aerator, including support plate 1, non-return bolt 3, non-return gasket 4 and rubber diaphragm 5；It is described
The inside of support plate 1 be provided with inlet channel 2, the outlet side of inlet channel 2 is provided with venthole, in the outlet of support plate 1
Nose end is provided with the non-return bolt 3, the non-return gasket 4 is provided in the lateral surface of non-return bolt 3, in support plate 1
Upper surface be provided with the rubber diaphragm 5.
Illustrate the specifically used state of the utility model below：
When aerator works normally, the air-flow in inlet channel 2 is open-top by non-return gasket 4, and air-flow is normally produced；It exposes
When gas device is stopped, non-return gasket 4 is re-attached to the surface of non-return bolt 3, prevents sewage under the action of hydraulic pressure from film
It is back at hole in aerating system pipeline.
The above-mentioned description to embodiment is it will be appreciated that and using this for the ease of those skilled in the art
Case technology, person skilled in the art obviously can easily make these examples various modifications, and described herein one
As principle be applied in other embodiments without having to go through creative labor.Therefore, this case is not limited to above example, ability
For the technical staff in domain according to the announcement of this case, the improvement made for this case and modification all should be in the protection domains of this case.
