Abstract
The utility model discloses a red mud settling device for alumina production, which comprises a plurality of stages of settling tanks and a plurality of stages of hydrostatic mixing tanks, wherein each settling tank comprises an overflow pipe and an underflow pipe, and a bottom discharge hole of each hydrostatic mixing tank is connected with a pressure pump; the overflow pipes and the underflow pipes of the settling tanks needing mixing are respectively communicated with the top feeding holes of the corresponding hydrostatic mixing tanks by pipelines, and the bottom discharge holes of the hydrostatic mixing tanks are connected with the feeding holes of the corresponding settling tanks by pressure pumps and pipelines. The utility model are provided with the hydrostatic settling tanks on the basis of an original settling device and enables overflows and underflows of the settling tanks to be fully mixed in the hydrostatic mixing tanks and then enter the settling tanks so as to be beneficial to settling, improve the production capability of the settling tanks and improve the red mud washing efficiency. Meanwhile, overflow pipes and underflow pipes in the original settling device are replaced by the pressure pumps of the hydrostatic mixing tanks to save power and reduce energy consumption.
Description
Technical field
The utility model relates to alumina producing equipment, especially a kind of alumina producing red-mud settlement device.
Background technology
In the alumina producing, need with subsider sedimentation red mud, subsider generally is provided with multistage by front and back in proper order, and return subsider again after need making the underflow of preceding what subsider and afterwards the overflow of what subsider mixing and carry out sedimentation, but in the existing sedimentation device, the underflow of each subsider and overflow are directly to inject corresponding subsider with pump, overflow and underflow can not mix equably, and every subsider all need dispose underflow pump, overflow type pump, more with pump, be prone to fault, Working environment is relatively poor, has a strong impact on the ordinary production of red-mud settlement.
The utility model content
The purpose of this utility model is to provide a kind of can make subsider overflow and the well-mixed alumina producing of underflow red-mud settlement device.
The technical solution of the utility model is: a kind of alumina producing red-mud settlement device, comprise multistage subsider, each subsider has upflow tube and underflow pipe, this device also comprises multistage hydraulic type tempering tank, the bottom discharge mouth of each hydraulic type tempering tank is connected with pressure pump, the described upflow tube of blended subsider and the underflow pipe of respectively needing all is communicated with by its top feed mouth of the pipeline hydraulic type tempering tank corresponding with each, and the discharge port of each hydraulic type tempering tank bottom is connected by the opening for feed of pressure pump and the pipeline subsider corresponding with each.
The cell body bottom of described hydraulic type tempering tank is taper.
The utility model is to install the hydraulic type subsider on the basis of initial settlement device additional, the utility model can make subsider overflow and underflow enter subsider behind the thorough mixing more in use in the hydraulic type tempering tank like this, and help sedimentation, improve the energy of giving birth to of subsider, increase the efficient of laterite washing; Replace overflow type pump and underflow pump in original device with the pressure pump of hydraulic pressure tempering tank simultaneously, can save power, reduce energy consumption.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, sedimentation device of the present utility model, comprise 1#～6# subsider 1,2,3,4,5,6,1#～4# hydraulic type tempering tank 7,8,9,10, each hydraulic type tempering tank 7,8,9,10 includes the bottom for the cell body of taper be connected in the pressure pump 11,12,13,14 of cell body bottom discharge mouth, 15 is thick liquid bath among the figure, and 16 is the washing lotion groove, and 17 is pressure filter.Respectively need the upflow tube and the underflow pipe of blended subsider all to be communicated with by its top feed mouth of the pipeline hydraulic type tempering tank corresponding with each, the pressure pump of each hydraulic pressure tempering tank is communicated with its top feed mouth of each corresponding subsider by pipeline.The utility model is when work, and subsider overflow and underflow be thorough mixing in the hydraulic type tempering tank earlier, then the material that mixes is squeezed in each corresponding hydraulic type tempering tank by pressure pump again.
Claims (2)
1, a kind of alumina producing red-mud settlement device, comprise multistage subsider, each subsider has upflow tube and underflow pipe, it is characterized in that: this device also comprises multistage hydraulic type tempering tank, the bottom discharge mouth of each hydraulic type tempering tank is connected with pressure pump, the described upflow tube of blended subsider and the underflow pipe of respectively needing all is communicated with by its top feed mouth of the pipeline hydraulic type tempering tank corresponding with each, and the discharge port of each hydraulic type tempering tank bottom is connected by the opening for feed of pressure pump and the pipeline subsider corresponding with each.
2, alumina producing according to claim 1 red-mud settlement device is characterized in that: the cell body bottom of described hydraulic type tempering tank is taper.
