Self-cleaning filtering membrane device

Abstract

The invention discloses a self-cleaning filtering membrane device which comprises a membrane shell and a central tube, wherein the central tube passes through the membrane rotatably and horizontally, one end of the central tube is fixedly connected with a filtering membrane stack, the other end of the central tube is fixedly connected with a rotating device, the filtering membrane stack and the rotating device are both positioned in the membrane shell, a spraying device is arranged on the membrane shell and above the filtering membrane stack, and a liquid outlet is arranged at the bottom of the membrane shell; a through hole is formed on the part, corresponding to the filtering membrane stack, of the central tube; a guide hole is formed on the part, corresponding to the rotating device, of the central tube; and the rotating device is rotatably arranged by virtue of the liquid flowing out of the guide hole. In the embodiment of the invention, the rotating device drives the central tubeand the filtering membrane to rotate continuously, and the surface of the filtering membrane is flushed and cleaned all the time since liquid is continuously sprayed on the filtering membrane stack by the spraying device.

Description

technical field [0001] The invention relates to a filter, in particular to a self-cleaning filter membrane device which can be used for treating sewage and waste water. Background technique [0002] After the filter membrane has been used for a period of time, a large amount of dirt is trapped on the surface of the filter membrane. If it is not cleaned, it will not only affect the quality of the filtered water, but also reduce the service life of the filter membrane. Therefore, the filter membrane must be cleaned to restore the filter membrane. Normal filtering effect. [0003] At present, many filter membranes are cleaned manually, manually, and mechanically, which requires a lot of manpower and material resources, and the operating cost is very high. Contents of the invention [0004] The purpose of the present invention is to provide a self-cleaning filter membrane device, the rotating device drives the central tube and the filter membrane to rotate continuously, becau...
