The technical solution of the utility model: a kind of density, pH value and chlorine ion concentration pick-up unit of desulfurated plaster slurries, outside is provided with Density Detection mouth, pH value detects mouth and the outlet of desulfurated plaster slurries; The above and below of housing is respectively equipped with upper sealing plate and lower shrouding, and lower shrouding is provided with desulfurated plaster slurries entrance; Enclosure interior is provided with center mozzle and mozzle support, and center mozzle is fixed on mozzle support; The outlet of desulfurated plaster slurries is connected with desulfurated plaster slurries vent pipe, on housing, be also provided with chlorine ion concentration and detect mouth, chlorine ion concentration detects mouth and is provided with chlorine ion concentration pick-up unit, can detect the chlorine ion concentration of the desulfurated plaster slurries in housing by chlorine ion concentration pick-up unit.Center mozzle is provided with mounting hole.Mounting hole is wherein set on the mozzle of center and makes to enter the desulfurated plaster slurries maintenance boiling shape in housing, avoided the appearance of deposition, fundamentally solved equipment lower end because precipitating the problem of the obstruction causing.
In density, pH value and the chlorine ion concentration pick-up unit of aforesaid this desulfurated plaster slurries, housing is also provided with underflow discharge pipe, and the other end of underflow discharge pipe and desulfurated plaster slurries vent pipe are connected.Make to be desulfurized sediment that gypsum slurries breaks up by flowing into desulfurated plaster slurries vent pipe in underflow discharge pipe.
In density, pH value and the chlorine ion concentration pick-up unit of aforesaid this desulfurated plaster slurries, Density Detection mouth is provided with device for detecting density, and pH value detects mouth and is provided with pH value detection device.
In density, pH value and the chlorine ion concentration pick-up unit of aforesaid this desulfurated plaster slurries, mounting hole is 30～45mm apart from mozzle one end, center, and 2～8 mounting holes are distributed on the same sagittal plane of center mozzle.
Compared with prior art, this utility model can detect desulfurated plaster serum density and pH value more exactly, especially can also accurately detect the chlorine ion concentration in desulfurated plaster slurries, can effectively solve desulfurated plaster slurries porch the problem of stopping up easily occurs by be provided with mounting hole on the mozzle of center simultaneously, guarantee pick-up unit can be steadily, continuous working.Staff or equipment have comprehensively, monitor accurately and control the various factors of the quality that affects desulfurated plaster slurries, better produce the gypsum of high-quality.
