disc is multi-disc type wash engine of the present invention, its effect is Filter slurry and forms pulp layer in filter disc card, each filter disc is made up of some stainless steel fanning strips, filter screen is covered with outside fanning strip, fanning strip is screwed on main shaft, Fig. 3 is the schematic diagram of main shaft, in figure, 41 are depicted as the end face installing distributing valve, point several passages in main shaft 4, 42 are depicted as a filtrate runner, be communicated with the fanning strip often coiled respectively, 43 are depicted as filter disc runner, filter disc refers to filter disk, main shaft and fanning strip root rubber seal, 44 are depicted as fanning strip installation position, spindle end by roller bearings on the support of cell body, the 45 reductor end spindle noses being depicted as main shaft, suspension speed reducer shaft is hollow-core construction, be suspended on driving end spindle nose, the other end by roller supporting on the support of cell body, and connect with distributing valve, the operation principle of distributing valve is: each discharge opeing outlet of rotating disk main shaft is connected with distributing valve, wherein spool encloses section port, and whole circumference is divided into Liang great Qu: region of no pressure, stripping slurry and exhaust area.When filtration disk often circles, each leakage fluid dram is successively by vacuum filtration district, stripping slurry and exhaust area.Often circle processes such as just realizing suction strainer, washing, discharging.The sealing property quality of distributing valve seal box directly affects the vacuum of equipment, thus affects the production capacity of equipment.Distributing valve is primarily of seal box, and seal box comprises main shaft filtrate (liquid end face, valve chamber, valve road, sealing device etc. and regulating spool two large divisions and other relevant portion as compositions such as vacuum meter, water legs.Fig. 4 is the schematic diagram of distributing valve, and main shaft junction is provided with sealing 51, distributing valve has spool 52, valve chamber 53, vacuum meter interface 54, atmospheric region runner 55, region of no pressure runner 56.Upper cover 3 is by left and right sidesing wall plate, the parts such as intermediate beam and cover plate form, stripping sizing device, on the left and right sidesing wall plate that net washing device is supported on upper cover and intermediate beam, cover plate has window, push movable cover plate above open, the i.e. ruuning situation of observable each several part, gas hood both sides are equipped with exhaust port, connect blast pipe for user, the effect of wash mill makes pulp layer obtain uniform drip washing, and the displacement washing realizing black liquor in pulp layer filters.It is primarily of compositions such as sluicing pipe, nozzle, control valves.Having four showers is arranged on the scrubbing section of rotary drum, at a distance of 13o-16o.Require that pulp layer enters second drip washing after first drip washing is filtered dry, and pulp layer should obtain uniform drip washing.Shower hydraulic pressure flow can by respective valve regulated, sluicing pipe nozzle stainless steel manufactures, they are staggered, be convenient to wash even and can prevent washings from interfering, this disc type vacuum pulp washing machine adopts air doctor blade stripping slurry, as shown in Figure 2, the blast certain by fan with low voltage and air quantity make pulp layer peel, stripping sizing device is primarily of blower fan, air blast pipe, cutter hub, blade forms, net washing device realizes by being arranged in the multiple (operating) water nozzles washing barrier, (operating) water nozzle connects the water supply of certain pressure, drive unit is by frequency control motor, suspension type gear speed reducer forms, filtering disk filter disc main-shaft spindle head is connected directly between on reductor hollow shaft, by key connecting, reductor one end is made to hang on rotary drum axle, the other end is supported by a pull bar, filter disc rotating speed is needed to select optimum speed voluntarily in 0.7-2.5r/min according to technique by user, discharging spiral is connected under receiving hopper, discharging spiral is mainly accepted the slurry transferring peeled from filter disc and is used.
The course of work of the present invention is: when main shaft drives filtration disk filter disc to turn to below liquid level, fanning strip enters air filtering area, namely the atmospheric region shown in Fig. 1, first in natural filtration district because net inside and outside differential pressure slurry starts to form pulp layer on the net, main shaft is rotated further, fanning strip enters vacuum filtration district, namely the region of no pressure shown in Fig. 1, liquid in cell body slurry is through filter screen, main shaft enters water leg by distributing valve and forms vacuum, liquid passes filter screen in a large number and forms pulp layer filter cake and thicken gradually, after filter disc produces liquid level, vacuum action does not disappear at once, enter displacement washing district, pulp layer on filter disc is subject to the repeatedly displacement washing of spray liquid, main shaft is rotated further, dead band on distributing valve, vacuum action disappears, filter disc enters Bao Jiang district, slurry is peeled off by air doctor blade in Bao Jiang district.Main shaft is rotated further, after washing barrier nozzle spray and washing net, recovery filter capacity, enter the next filtration washing cycle.
After describing various specific embodiment of the present invention above in detail, those of ordinary skill in the art should be well understood to, according to the various common practise of this area, can carry out various equivalent variations, equivalent replacement according to thinking of the present invention or simply revise, these all should belong to the scope of technical solution of the present invention.
