Embodiment
as shown in Figures 1 to 6, the osmosis device for dehydrating sladge waste that the present embodiment provides mainly comprises frame 1, sludge dehydration device, driving mechanism, power supply (not shown), hopper 3, material scraper 4.Below the concrete structure of sludge dehydration device and driving mechanism is elaborated.
in this example, sludge dehydration device comprises the ring-shaped guide rail 20 being fixed in frame 1, a plurality of web plate dolly 21, a plurality of mobile web plate 22, a plurality of cylinder 23, conducting plates 24 and the sewage dish 25 that is positioned at mobile web plate 22 belows.The medullary ray along continuous straight runs of ring-shaped guide rail 20 extends, and the top of ring-shaped guide rail 20 is straight path 200.Ring-shaped guide rail 20 is two of be arrangeding in parallel, and the conducting plates 24 of long strip shape is installed at least one of two ring-shaped guide rails 20.
web plate dolly 21 comprises vehicle frame 210, is arranged on the wheel 211 of vehicle frame 210 bottoms.Mobile web plate 22 levels are arranged on the top of vehicle frame 210, and wheel 211 can be arranged on ring-shaped guide rail 20 movably along the track of ring-shaped guide rail 20.Particularly, the long-width ratio of vehicle frame 210 is 3:1, and wheel 211 comprises the both sides of the length direction that lays respectively at vehicle frame 210 and two pairs of wheels of symmetrical setting, and two pairs of wheels of web plate dolly 21 are separately positioned on two ring-shaped guide rails 20.On the straight path 200 of ring-shaped guide rail 20,21 1, web plate dolly is pasting a setting, and a plurality of mobile web plate 22 on a plurality of web plate dollies 21 has been spliced to form a large mobile web plate successively.In addition, the both sides of the length direction of the mobile web plate 22 on vehicle frame 210 are also separately installed with the length that distance between baffle plate 212, two side shields 212 that are made by insulating material equals mobile web plate 22.
a plurality of cylinders 23 are arranged side by side in equally spaced mode in the consistent direction of the bearing of trend of the straight path 200 with ring-shaped guide rail 20, a plurality of cylinders 23 that these are arranged side by side and the distance between ring-shaped guide rail 20 are successively decreased successively, wherein, the cylinder 23 of the most close hopper 3 and the distance between ring-shaped guide rail 20 are maximum, the most minimum away from cylinder 23 and the distance between ring-shaped guide rail 20 of hopper 3.Cylinder 23 can be arranged in frame 1 rotationally around Pivot Point Center line, under the effect of driving mechanism, rotates.By a plurality of mobile web plate 22 of the movement on the straight path 200 of a plurality of cylinders 23 that rotate and ring-shaped guide rail 20, match mud is pushed.Meanwhile, mobile web plate 22 and cylinder 23 are made by the metallic substance of conduction, and wherein mobile web plate 22 is connected with the negative electrode of power supply by resilient connector 214, conducting plates 24 in the moving process of web plate dolly 21.
in this example, driving mechanism comprises drive part and the drive part for driving web plate dolly 21 to move rotating for head roll 23.For these drivings, there is no special requirement, all can implement with reference to known conventional means.In this example, for driving the drive part of web plate dolly 21 motions, be that motor drives, sprocket wheel chain type of drive.Specifically, by motor driving chain wheel shaft 5, band movable sprocket, then by chain wheel drive chain 6, chain 6 is connected with the vehicle frame 210 of web plate dolly 21 by dragging axle 213.Open motor, chain 6 drags web plate dolly 21 along the orbiting motion of ring-shaped guide rail 20.
the principle of work of dehydration equipment of the present invention is as follows: head roll 23 rotates, and drives web plate dolly 21 to move along the track of ring-shaped guide rail 20, switches on power.By mud from hopper 3 passes into, mud enters on the mobile web plate 22 on the straight path 200 of ring-shaped guide rail 20, and be extruded under the cooperation of the cylinder rotating 23 on top and the mobile web plate 22 moving of bottom, simultaneously, under the effect of electrophoresis, the moisture of mud will be extruded, and flow to sewage dish 25 and be discharged from dehydration equipment through mobile web plate 22.Because the both sides at mobile web plate 22 are provided with baffle plate 212, on whole mobile web plate 22, mud can keep same thickness, compares with not baffled 212 situation, can improve the efficiency of lignin-sludge and the Disposal quality of raising mud.Take dehydration equipment of the present invention, can give full play to the usefulness of osmosis, the sludge cake water content after squeezing can be reduced to below 50% or even 40%.
above the present invention is described in detail; its object is to allow the personage who is familiar with this art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; the equivalence that all spirit according to the present invention are done changes or modifies, and all should be encompassed in protection scope of the present invention.
