Two-stage rotating purification device

Abstract

The invention discloses a two-stage rotating purification device. The two-stage rotating purification device comprises a fixing frame, 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, a first membrane piece is mounted on the outer circumferential wall of the rotating drum in a sleeve manner, 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 via the mounting hole, the side wall of the filtering drum is connected with a liquid inlet pipe, a filtering plate is inserted and mounted in the filtering drum, multiple second filtering holes are formed in the filtering plate, second membrane pieces are fixedly mounted on the upper surface and the lower surface of the filtering plate, and a positioning groove where the head end of the filtering plate is inserted and mounted is formed in the inner side wall of the filtering drum. With the adoption of the two-stage rotating purification device, problems of concentration polarization of membrane surfaces and membrane pollution can be well solved, and the purification effect of the device is significantly improved.

Description
