Guide shell mixing device
Technical field
The utility model relates to a kind of equipment sewage and medicament fully being contacted mixing.
Background technology
Sewage source in industry, life, plant etc., as mine drainage, animal farm wastewater, sanitary sewage, electric power plant circulating water etc.Containing the material that a large amount of heavy metal ion, suspended substance, intestinal bacteria etc. is harmful in waste water, and pollutent mainly exists in colloidal form, and waste water could discharge after treatment, therefore must ensure fully contacting of sewage and medicament in treating processes.Due to the continuous injection of sewage and discharge in dosing steel basin, make part of contaminated water and medicine have little time to react and just discharge, affect treatment effect.Therefore the task of top priority is become for sewage with the research and development of the treatment facility fully contacted of medicament.
Utility model content
The utility model object is the deficiency overcoming above-mentioned prior art, provides a kind of sewage and medicament of effectively making fully to contact the waste mixing, avoid medicament, the guide shell mixing device reducing running cost.The utility model includes tank, guide shell, stirrer, stir shaft, jackscrew, agitating vane and gusset; Sink top is respectively equipped with water-in and feeding opening, and guide shell comprises the hydraucone of straight tube and straight tube lower end, and hydraucone is welded on straight tube bottom, and guide shell straight tube is fixed on sink center position by gusset and tank wall, and the upper and lower two ends of guide shell are uncovered; Agitating vane is contained on stir shaft, stirrer is connected and fixed on sink top by ring flange, and stir shaft is connected fastening with stirrer by shaft coupling, and agitating vane is evenly fixed on stir shaft by jackscrew, stir shaft is positioned at guide shell, flushes bottom stir shaft with bottom guide shell.
Guide shell straight tube upper end distance sink top distance is 30-50mm, and hydraucone lower end, guide shell bottom distance bottom of gullet is 30-50mm, and the upper and lower two ends of guide shell are uncovered; The bell-mouthed opening angle in guide shell bottom is 60 °; Guide shell straight tube internal diameter 20mm larger than the rotating diameter of agitating vane.Water-in, feeding opening all directly stretch in guide shell, are conducive to the better fusion of medicine and sewage.
Sewage, medicament enter guide shell from water-in, feeding opening respectively simultaneously, by the stirring of stirrer, impose downward power, sewage and medicament are discharged from the below hydraucone of guide shell upon mixing, then the top water-in of guide shell is back to, continue circulation stirring, waste water is contacted fully with medicinal powder, mixes, repeatedly stir and make waste water and medicament rapid reaction.
The utility model compact construction, easy to operate; Use range is wide, is applicable to mixing of any liquid and powder; Sewage can be made fully to mix with medicament; Greatly reduce added amount of chemical, effectively reduce running cost.
