Description
Technical field
The present invention relates to a kind of stirred tank, specifically a kind of safety and environmental protection sewage disposal stirred tank.
Background technology
Either life or production can all use water resource, after these water resources are previously used, become in order to waste water,
Sewage, annual people can generate many sewage, but the overwhelming majority can be exhausted directly in this part of contaminated water, not entered into
Sewage treatment plant, but flow directly into river, therefore the source for saving water has been very urgent, it cannot be only from every but save water
It is few to be used for carrying out, and processing is also carried out to sewage and enables utilizing, even if can not practicality can not be to existing again
Environmental effects, can be related to many steps in the technology of sewage disposal, various oxidation ponds, sedimentation basin all can by with
It arrives, large-scale sewage treatment plant's floor space also can be very big, but we cannot only rely only on sewage treatment plant and carry out sewage
Processing oneself will also understand carry out sewage disposal, therefore country recommends private small factory that will build the sewage disposal device of oneself,
The sewage disposal machinery for possessing oneself, in traditional sewage disposal technology, sewage first has to by precipitation then dosing, filtering
Etc. multiple steps, the technology that most starts all be take out bigger suspended matter and sediment using physical method, but it is this from
The right sedimentation time is too slow, therefore technical staff can be added reagent in no oedema and be chemically treated, but reagent needs after being added
It is more thorough that stirring can just be such that sewage is combined with reagent, be the epoch of mechanization now, therefore mechanical agitation has become mainstream, stir
The quality for mixing effect depends on the quality of stirrer paddle, and in whipping process, sewage can generate impact to blade, and in sewage
Impurity and chemical agent blade can all be corroded, therefore general rabbling mechanism is the component for being easiest to damage, tradition
Although rabbling mechanism agitating shaft and blade be also separated structure, often paddle is all integral installation, three traditional leaves
For blade once damaging any of which one, then whole to replace and traditional blade installation is also inconvenient.And stirred tank
Itself or external capital generate prodigious vibrations when work is either mobile, this will produce stirred tank itself
Prodigious influence, and the shakiness of stirred tank can also have an impact mixing effect.
