Four, description of drawings
Fig. 1: be the utility model red mud filter structural representation;
The vertical view of Fig. 2: Fig. 1;
Fig. 3: use filtering technique schematic flow sheet of the present utility model.
Five, the specific embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.
The red mud filter of present embodiment drags continuous operation by motor 25 through reductor by the annulus rubber cincture 3 on the frame of shaped steel welding with reference to Fig. 1-2, and synchronous operation with it on rubber strip 3 is applied in filter cloth 1 shop.Rubber strip 3 and vacuum chamber 6 sliding-contacts (annular friction tape is arranged between vacuum chamber and rubber strip and feed water and form water-stop) when vacuum chamber 6 is connected vacuum system, form the vacuum filtration district on rubber strip 3; Cloth is on filter cloth 1 equably by feed hopper 5 for slip, and under the effect of vacuum, filtrate is passed the traverse furrow groove of filter cloth 1 on rubber strip 3 and gathered and enter vacuum chamber 6 by aperture, and solid particle is trapped and forms filter cake; The liquid that enters vacuum chamber 6 is discharged through steam-water separator.Enter the filter cake scrubbing section successively along with rubber strip moves established filter cake, blot the district; Last filter cloth 1 separates with rubber strip 3, by scraper 11,12 filter cake is drawn off; The filter cloth 1 of removal filter cake obtains regeneration after cleaning; Again through reentering filtering area behind one group of tensioning apparatus 24 and the deviation correcting device 23.Whole process by each accessory system such as stay-warm case 7, elution device 10, brush roll, cleaning case 15, vacuum dehydration pipe 16, dipping by lye groove 19, supersonic wave cleaning machine 21, clean bucket 22, make it under the environment of a sealing, constant temperature, to carry out work, this has not only improved the rate of recovery of red mud greatly, and has prolonged filter cloth service life.
Technological process:
Adopt cyclone fraction level Bayer process dilution rear slurry, underflow advances red mud filter to be separated and washs, and the sedimentation separation of subsider flocculant is advanced in overflow.First-time filtrate after the filtration is mixed with the washing settling groove primary wash liquor, removes the stripping dilution trap; Two, three washing lotion filters self use; Red mud filter cake is gone into the filter cake groove, is discharged to the red mud storage tank by the filter cake pump.Red mud filter cake moisture is about 40～45%, below the dried red mud of attached alkali 7kg/t-, also can directly efflux.
The filter that present embodiment provides comprises filter cloth 1 belt being flat on the rubber strip 3, and rubber strip 3 is surrounded on drive roll 13, the driven voller 2, and motor 25 drives reductors and directly drives drive roll 13.The red mud slip on filter cloth 1, and enters stay-warm case 7 by dragging of filter cloth 1 through feed hopper 5 even cloth, and beginning is dry under the pull of vacuum of vacuum chamber 6, and the moisture of generation is drained by discharging tube 27, Drainage tank 28.Dry run can be observed by form 9, is provided with temperature controller 8 in the stay-warm case 7 to keep constant temperature at 50 ℃-60 ℃, and there is elution device 10 dry back to clean filter cake by scraper 11,12 dischargings before scraper.Unsnatch filter cloth 1 behind the material and enter cleaning case 15 and clean, have brush roll auxiliary in the cleaning case.Vacuum dehydration pipe 16 is arranged behind the cleaning case 15, and vacuum pressure 0.5Mpa is to blot the moisture in the filter cloth.Enter dipping by lye groove 19 after blotting, dipping by lye groove 19 is cell bodies of a sealing, and alkali lye circulates in groove to keep constant temperature by charging aperture 17, discharging opening 20.There is one group of ultrasonic cleaning equipment 21 at dipping by lye groove 19 rears in order to pulverize bigger particle in the filter cloth 1, have improved the effect of cleaning greatly.Last filter cloth 1 cleans residual alkali lye or particle by cleaning bucket 22.Filter cloth 1 is by deviation correcting device 23 and tensioning apparatus 24 failure-free operation continuously.Whole process comprises the automation control of wash water and eluent flow, temperature: the real fully plc of employing of wash water temperature realizes Automatic Control in conjunction with automatic valve, temperature controller, flowmeter, liquid level gauge etc., avoids the big filter cloth regeneration effect that influences of variations in temperature.
