Device drives the rotation of cathode swingle, and controls rotation speed, mixing blade is provided on cathode swingle, in electroosmotic dewatering
During can stir sludge, improve dehydration efficiency；
(7) drawer type water storage storage hopper dredger penetrates supporting network and is stored in drawer type water storage for storing water and mud cake, water in the present invention
Hopper dredger bottom is stored up, mud cake is fallen on supporting network, and the storage of drawer type water storage uses drawing and pulling type structure, is convenient for disassembly and is poured out water and mud
Cake；
(8) present invention is mounted with that atomizing spills medicine device in electro-osmosis reactor head, and it includes setting two that atomizing, which spills medicine device,
A syringe, can apply medicament by period, seal between syringe outer circle and connection inside pipe wall, and syringe is to drug storage
Inside box when injection medical fluid, there is certain pressure, medical fluid is sprayed by the spray micropore mist of medicinal box bottom, is uniformly sprinkled upon
On sludge, it can be sufficiently mixed by the stirring of cathode swingle.
(9) area minimized into mud mouth into mud mouth is arranged in electro-osmosis reactor bottom in the present invention, in this way may be used
Increase the surface area of anodal barrel as far as possible, to improve dehydration efficiency and effect, by operating dismountable hinge, in dress mud and takes
Mud cake process is also convenient and efficient out.
