The invention discloses an arc-shaped plate type electric field anode rack structure. The arc-shaped plate type electric field anode rack structure comprises a cathode rack assembly, insulators, an anode rack frame and cathode needles, wherein the cathode needles are mounted on the cathode rack assembly; grooves are formed in four sides of the anode rack frame; each groove internal sealing plate is mounted in the corresponding groove of the anode rack frame; two baffles with holes are respectively mounted at two ends of each groove internal sealing plate; each fixing baffle is mounted on the corresponding groove internal sealing plate; each insulator is fixedly mounted on the corresponding fixing baffle through a bolt; groove external sealing plates are mounted on the anode rack frame and are fastened with the groove internal sealing plates to seal the insulators; and an arc-shaped anode plate is mounted inside the anode rack frame. The problems of low lampblack treatment efficiency, complicated structure and troublesome cleaning and maintaining are solved, lampblack is attached to the arc-shaped anode plate, therefore, the lampblack treatment efficiency is improved, a cleaning and maintaining period is shortened, and the problems of later-period maintenance and troublesome change are greatly avoided. The arc-shaped plate type electric field anode rack structure has the advantages of low working energy consumption and long service life of a global device.
