Description

Technical Field

[0001] The present application relates to the field of flocculation sedimentation tanks, and more particularly to a filtering device for a flocculation sedimentation tank. Background Art

[0002] A flocculation sedimentation tank is an efficient combined sedimentation tank designed based on the theory of shallow tank sedimentation, also known as an inclined tube sedimentation tank. The main principle of this type of tank is to set many dense inclined tubes or inclined plates in the sedimentation area, so that the suspended impurities in the water precipitate in the inclined plates or inclined tubes. The water flows upward along the inclined plates or inclined tubes, and the separated sludge slides down along the inclined tubes to the bottom of the tank under the action of gravity and is then discharged centrally.

[0003] Regarding the above related technologies, the inventor believes that after a conventional flocculation sedimentation tank is used for a period of time, due to the fact that the water flow contains more impurities, when discharging, the situation of impurity blockage in the external discharge pipeline often occurs, which requires the staff to spend time cleaning and affects the use of the flocculation sedimentation tank.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

The bottom end of the fixing frame is fixedly installed on the top of the shielding plate. The size specification of the surface of the shielding net is adapted to the size specification of the surface of the shielding plate. The two rotating rods are symmetrically distributed with the shielding net as the axis of symmetry, and the rotating rod and the fixing frame are perpendicular to each other.
