The infall process of nanometer powder in nano powder slurry settling tank: see Fig. 3, the nanometer powder slurry that the machine of being centrifuged is separated directly pours into charging feed bin; Slurry passage A from charging feed bin through feeding warehouse overflow plate top enters sedimentation feed bin, by sedimentation feed bin infall process, by the nanometer powder of sedimentation, through slurry passage D front portion, entered nanometer powder and collect feed bin, remaining nanometer powder slurry is from sedimentation feed bin after on sedimentation feed bin, turn back in short swash plate bottom, then the slurry channel B on long swash plate top enters baffling feed bin on sedimentation feed bin; At baffling feed bin, pass through baffling feed bin infall process, by the nanometer powder of sedimentation, through slurry passage D middle part, entered nanometer powder and collect feed bin, remaining nanometer powder slurry is first after on baffling feed bin, turn back in short swash plate bottom, on baffling feed bin, the slurry passage D of long swash plate bottom middle part enters nanometer powder and collects feed bin again, then through slurry passage D rear portion, enters overflow feed bin by nanometer powder collection feed bin; At overflow feed bin, through overflow feed bin infall process, entered nanometer powder collect feed bin by the nanometer powder of sedimentation through slurry passage D rear portion, remaining nanometer powder slurry enters discharging feed bin through the slurry channel C on overflow plate top; Finally at discharging feed bin, nanometer powder slurry, after last infall process, becomes the liquid that meets discharge standard, through the outlet valve of right plate, to delivery pump B output, send sewage disposal device to process.The nanometer powder that nanometer powder is collected feed bin reclaims by nanometer powder collecting pipe.
Nanometer powder infall process mechanism: in Fig. 3, nanometer powder slurry enters charging feed bin, until fill charging feed bin, start the overflow through slurry passage A, overflow is to sedimentation feed bin, after whole jetsam feed bin is filled, the liquid level of sedimentation feed bin is higher than the height of charging feed bin overflow plate spreading mass passage A, so when liquid enters sedimentation feed bin from charging feed bin, that extruding enters sedimentation feed bin, to guarantee the smoothness of sedimentation feed bin liquid; Sedimentation liquid, from the entering at the middle and upper levels sedimentation feed bin of charging feed bin liquid layer, is more conducive to the sedimentation of nanometer powder like this, less to the impact of sedimentation feed bin sedimentation.Same reason, nanometer powder slurry, after the overflow of slurry channel B, has also played the smoothness that guarantees baffling feed bin liquid, also less to the impact of baffling feed bin sedimentation.When charging feed bin liquid level fill with to spout hole be slurry passage A, overflow is to sedimentation feed bin, sedimentation feed bin liquid level increases thereupon, surpasses feeding warehouse spout hole; When sedimentation feed bin liquid level fill with to spout hole be slurry channel B, overflow is to baffling feed bin, baffling feed bin liquid level increases thereupon, surpass charging feed bin and sedimentation feed bin spout hole, again through overflow feed bin, discharging feed bin, overflow feed bin, discharging feed bin liquid level are increased thereupon, surpass charging feed bin and sedimentation feed bin spout hole, sedimentation forms.The liquid that enters so again charging feed bin will start sedimentation work, how much liquid of having come in, overflow feed bin will how much liquid of overflow to discharging feed bin.
Compared with prior art, the invention has the beneficial effects as follows:
(1) nanometer powder slurry sinking speed of the present invention is fast, yield is high: at centrifuge, carry out continuously under the state of Separation of Solid and Liquid, what produce contains useful nanometer powder liquid material from centrifuge flows out continuously, can reclaim fast and efficiently and process, its design has continuity and high efficiency, realized two-forty and high effect, can useful nanometer powder reclaimed quite thoroughly.
(2) reasonable in design, occupies little space, and equipment is small: the design of declined board and nanometer powder collecting pipe has solved the difficult problem that nanometer powder difficulty is received in square precipitation apparatus bottom; In continuity infall process, the flow velocity of 3 cubes per hour, the equipment profile that the unpowered design without auxiliary material of tradition need to be made is quite large; The in the situation that of limited space, the present invention has reduced and has taken up room, and practicality is high, and equipment is easily transformed and safeguarded.
(3) meet environmental requirement: without any power facility, cell body material is pollution-free, settling efficiency is high, be simple and easy to maintainability has become environmental protection main points of the present invention; Useful heavy metal nanometer powder in heavy metal slurry is recycled to country and below row internal standard value, and meets continuity work, without any power and supplementary product onsumption, do not produce any pollution;
