Technical Field

The invention relates to the technical field of filters, in particular to an automatic cylinder filter for an MBR (membrane bioreactor) membrane process.

Background

Adopting MBR membrane process to treat sewage, and intercepting at the inlet of the membrane tank by using a cylindrical filter screen, a wedge-shaped steel wire mesh and the like because foreign matters are mixed to damage the membrane sheet and the hollow fiber membrane filaments; the problem of blockage can easily occur during the use process. The reason is that the direction of the water flow is from top to bottom, the intercepted garbage is accumulated on the surface of the filter screen to form a pollution layer, and once the pollution layer is fully distributed on the inner surface of the whole filter screen, the filter screen can only be stopped periodically to clean. The method for prolonging the cleaning period of the filter screen only can increase the area of the filter screen. Moreover, the cylinder filter screen is lack of an alarm device, if engineering personnel do not timely draw the filter screen, the filter screen is blocked, sewage cannot enter the membrane pool, and normal operation of the system is affected. Or sewage overflows into the membrane tank, and garbage enters the membrane tank along with the sewage, so that the water treatment effect is influenced.

As shown in fig. 1, an automatic type cylinder filter for MBR membrane process comprises a pipe body 2 with one closed end, a cylinder filter screen 6, a driving motor 4 and a stirring brush 7; the pipe body 2 is integrally provided with a water inlet 1 and an overflow port 5; the water inlet 1 is positioned in the middle of the pipe body 2; the overflow port 5 is positioned at the upper part of the pipe body 2, and the overflow port 5 is connected with an overflow alarm device; the driving motor 4 is fixedly arranged on the closed end of the tube body 2, and an output shaft of the driving motor 4 penetrates through the outer wall of the tube body 2 and extends into the tube body 2; the cylindrical filter screen 6 is detachably arranged in the pipe body 2; the stirring brush 7 is arranged in the cylindrical filter screen 6, a transmission shaft 3 is fixedly arranged on the stirring brush 7, and the transmission shaft 3 is in transmission connection with an output shaft of the driving motor 4; the driving motor 4 can drive the stirring brush 7 to rotate, and the inner part of the cylindrical filter screen 6 is washed by the stirring brush 7; the water inlet 1 is connected to a water inlet pump through a pipeline; the driving motor 4 and the overflow alarm device are connected to the control end; for more energy-conserving, can set up driving motor 4 to open regularly and close, perhaps with the intake pump interlocking, when the intake pump starts, driving motor 4 drives stirring brush 7 and rotates.

When the water purifier is used, the water inlet 1 is connected with a water inlet pipeline, water flow enters the pipe body 2 from the water inlet 1 and is discharged after being filtered by the cylindrical filter screen 6; the driving motor 4 drives the stirring brush 7 to rotate, and the inner surface of the cylindrical filter screen 6 can be cleaned while stirring; under the rotation action of the stirring brush 7, water flow rotates in the cylindrical filter screen 6, and when the water flow flows through the side wall of the cylindrical filter screen 6, the pollutant retained on the cylindrical filter screen 6 is taken away by the generated shearing force, so that the pollution layer on the surface of the cylindrical filter screen 6 is kept at a thin stable level; when rivers can't pass through drum filter screen 6, drum filter screen 6 need clear up or when changing promptly, the overflow mouth 5 outflow on 2 upper portions of body can be followed to the rivers to trigger overflow alarm device reminds the staff to change drum filter screen 6. The alarm signal can be sent to the computer control end, and the operating condition of the automatic cylinder filter can be seen by the staff in the duty room.

The design of the invention can clean the pollution layer in the cylinder filter screen in real time, effectively prevent the filter from being blocked, reduce the frequency of replacement and maintenance, prolong the service life of the cylinder filter screen and improve the sewage treatment efficiency.
