Description

Tubular membrane dredging device

Technical Field

The utility model relates to the field of membrane treatment, in particular to a tubular membrane dredging device.

Background

With the gradual increase of environmental protection requirements, the membrane separation technology has been widely used in industries such as food, medicine, environmental protection and the like. In the treatment of percolate, a tubular membrane is an important facility for constructing an MBR (Membrane bioreactor) system, and the tubular membrane faces the problem of membrane tube blockage due to the high concentration of activated sludge in the MBR system. After the tube membrane tube is blocked, the overflow area is reduced, the yield of the clear liquid of the system is reduced, the energy consumption is increased, and even the whole MBR (membrane bioreactor) system is crashed. Particularly, under the action of a circulating pump, the operating pressure is higher, once a tubular membrane tube is blocked, the sludge is gradually extruded and compacted, and great difficulty is brought to the subsequent membrane tube dredging work.

The dredging device for the tubular membrane tube disclosed in the patent CN207786355U is characterized in that when a worker operates the dredging device, the inner diameter and the length of the tubular membrane tube are small, the inner wall of the mode tube is easily touched when the downward extending inclination angle of the drill bit is small, and the drill bit is easily scratched through the inner wall of the tubular membrane tube.
