Adjustable double-stage-rotation purifying device

Abstract

The invention discloses an adjustable double-stage-rotation purifying device. The device comprises a fixed frame, an adjusting device, a casing, a rotating drum, a filtering drum and a first motor, wherein multiple first filtering holes are formed in the circumferential wall of the rotating drum, the outer circumferential wall of the rotating drum is sleeved with a first membrane piece, a liquid outlet is formed in the bottom of the casing, an end cover is detachably connected with the right end of the rotating drum, a first rotating shaft is fixedly connected onto the end cover and connected with an output shaft of the first motor, a mounting hole is formed in the left end side wall of the rotating drum, the filtering drum is communicated with the rotating drum through the mounting hole, the side wall of the filtering drum is connected with a liquid inlet pipe, a filtering plate is inserted in the filtering drum, multiple second filtering holes are formed in the filtering plate, and second membrane pieces are fixedly mounted on upper and lower surfaces of the filtering plate. The device can better solve the problems of concentration polarization of membrane surfaces and membrane pollution, the purifying effect of the device can be significantly improved, and the flow of the liquid flowing out of the liquid outlet can be adjusted according to actual operation conditions.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an adjustable two-stage rotary purification device.
