Abstract
The invention provides an automatic plugging eliminating dissolved gas releaser. The automatic plugging eliminating dissolved gas releaser is composed of a nozzle, a sprayer, a pull rod, a spring, a sleeve, an electromagnetic controller and a pulse control instrument. The pull rod is arranged in the sleeve, the nozzle is connected with the lower end of the sleeve, the sprayer is arranged in the nozzle to be connected with the pull rod, the contact portions of the sprayer and the nozzle have certain pressure through the spring, the electromagnetic controller is arranged at the top end of the sleeve, the outer portion of the electromagnetic controller is provided with the pulse control instrument, and the electromagnetic controller and the pulse control instrument are connected through a wire. During operation, high-pressure gas dissolved water flows into the sleeve from a liquid inflow pipe and flows out of a jet to generate micro-nano bubbles, when the jet is blocked, the pulse control instrument supplies power to the electromagnetic controller to push the sprayer of the pull rod to move downwards to increase the distance of the jet, blocked impurities are rapidly discharged out of the nozzle under push of the high-pressure gas dissolved water in the pipe, then power supply is stopped, and the sprayer of the pull rod is kept in a constant-pressure working state, so that the purpose of automatic plugging eliminating is achieved.
Description
Technical field
The present invention relates to the dissolved air release in a kind of sewage-treatment plant, during sewage disposal, pressure air-dissolving water is only
Have and just can discharge substantial amounts of micro air bubble by after this device blood pressure lowering energy dissipating.
Background technology
Dissolved air release device is in operation process, and the foreign material blocking taken by sewage is normal phenomenon,
After blocked, how to solve automatically to get rid of the problem of the foreign material that are blocked, molten gas release the most used
Device does not solves.
For with the most more advanced TV type third generation dissolved air release, it, after release blocking, is used
Artificial breather valve of opening outside flotation tank, connection compressed air gas source, with pressure air-dissolving water by release
Stifled thing is rinsed well, this only by manually just finding when to be blocked and use manually to close down breather valve
The method of unimpeded considerably increases the workload of operative employee, and this is the shortcoming existing for existing dissolved air release.
Summary of the invention
Present disclosure is: solving existing dissolved air release needs the shortcoming of artificial unimpeded, makes molten gas discharge
Device is when being blocked, it is possible to the periodically automatically tackling blockage dissolved air release of automatically tackling blockage, and its technical scheme is: it by
Nozzle, shower nozzle, pull bar, spring, sleeve pipe, electromagnetic controller, pulse control instrument form, and arrange in sleeve pipe
Having pull bar, nozzle to be connected with its lower end, shower nozzle is arranged in nozzle, and its center is connected with stay-bolt,
Being provided with spring in sleeve upper end, be provided with pull bar in spring, electromagnetic controller is arranged on cannula tip, electricity
Magnetic controller power lead is connected with the pulse control instrument being arranged on outside this dissolved-gas release.During operation, enter
High pressure dissolved air water in sleeve pipe toward the spout between lower end shower nozzle and nozzle from pipe inner high voltage district suddenly to pipe often
Nip discharge, sewage produces a large amount of micro-nano bubble, the pressure of spout by pull bar upper end spring to
Upper elasticity is shower nozzle and sealed nozzle, and electromagnetic controller is by the Infinite Cyclic set in pulse control instrument
The control program that time opening is closed with timing is operated, when spout is blocked by sewage foreign material, and pulse control
Instrument processed instruction electromagnetic controller enters unlatching energising work and pull bar is down pushed away certain distance, at this moment tight with nozzle
The shower nozzle that contiguity is touched also moves down certain distance under the promotion of pull bar, but the spray in the middle of nozzle and shower nozzle
Mouthful distance becomes big at once, the stifled foreign material of institute under the promotion of sleeve pipe inner high voltage dissolved air water rapidly outside discharge nozzle, when
After the stifled foreign material of institute are drained, pulse control instrument at once instructs electromagnetic controller entrance closedown power-off and quits work, this
Time by spring elastic reset up, pull bar and shower nozzle are up retracted original state and continue normal operation,
So Infinite Cyclic, thus reach automatically tackling blockage purpose.When waiting as shower nozzle unimpeded opening time and closedown
Between how much to come actual to determine according to the content of sewage foreign material, the instruction being arranged in pulse control instrument come
Become.
