Description
Technical field
The present invention relates to wet dressing sewage treatment equipment field, in particular to a kind of continuous subsider.
Background technique
In wet dressing, often needs a large amount of water and broken mineral to enter wet magnetic separator together and carries out magnetic separation,
After magnetic separation, remaining waste water is in the mixture contained compared with high suspended matter for obtaining similar mud after filtering, by National Industrial
Wastewater discharge standard regulation, waste water at this time need after purified treatment can direct emission, therefore, it is necessary to use continuous subsider
Natural subsidence is carried out to it, but since the time consumption of natural subsidence is longer, the small granular suspended matters in waste water are not easily settled,
In the case where not using sedimentation agent, a sedimentation time generally requires to expend several days, and enterprise is caused not connected on a large scale
National emission standard can not be fully achieved in it to the waste water for continuing and producing, and be discharged, and effect of settling is poor.
Summary of the invention
Goal of the invention of the invention is: in view of the above problems, providing a kind of the case where not using sedimentation agent
Under, the continuous subsider of energy rapid subsidence, to solve the problems, such as that existing subsider faces inefficient.
The technical solution adopted by the invention is as follows: a kind of continuous subsider, including round groove body, it is intracorporal to be set to circular trough
Agitating device, the purified liquor outlet set on round groove body top, the round tapered formation plasma discharge bottom plate in groove body lower part, plasma discharge bottom plate
Bottom end opening forms thick slurry outlet, and the top of agitating device is equipped with material well, expects that the upper opening of well is connect with feed pipe, stir
Mixing device includes agitating shaft and the stirring wheel disc set on agitating shaft lower part, and the top of agitating shaft passes through material well and power device connects
It connects, expects that the upper end of round groove body is fixed on the top of well by more locating rods, expect that circle is fixed on by mud retaining plate in the lower part of well
The middle and upper part of shape groove body, the space between locating rod and mud retaining plate form supernatant layer, and the opening of purified liquor outlet is set in supernatant layer.
Due to the setting of above structure, the slurry of mineral containing high concentration is through feed pipe and by expecting that well enters continuous sedimentation
In slot, the agitating shaft of agitating device drives stirring wheel disc light to slurry of mineral with the speed of 0.1-1rad/min by power device
Micro- stirring, so that the thick slurry energy quick collecting for being deposited in the plasma discharge bottom plate of round groove body lower part is exported in thick slurry, then through thick slurry
Outlet discharge, in the process, agitating device is shaken in impact caused by slurry of mineral in order to prevent, expects the top of well by more
Locating rod is fixed on the upper end of round groove body.Meanwhile in order to quickly obtain clear liquid, to improve the rapid subsidence of continuous subsider
