Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a filtering device for sewage treatment. Background Art

[0002] The filtration device for sewage treatment has multiple uses. It effectively removes suspended matter, particulate matter, oil and other impurities in sewage through physical methods, significantly improving water quality. It can also remove harmful substances in sewage, such as heavy metals, organic matter, ammonia nitrogen, etc., reducing pollution to the environment.

[0003] According to a sewage treatment filter device disclosed on the patent website (authorization announcement CN 219399176U), "A sewage treatment filter device comprises: a sedimentation tank, wherein a quadrangular pyramid-shaped filter tank is disposed within the sedimentation tank, a rotating shaft assembly is connected to the top of the sedimentation tank near the side wall, an L-shaped plate is connected to the rotating shaft assembly, and the rotating shaft assembly is connected to the quadrangular pyramid-shaped filter tank via the L-shaped plate."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use of the utility model, the device filters particulate impurities in sewage through a quadrangular pyramid filter box, and when the quadrangular pyramid filter box needs to be cleaned, the motor drives the rotating shaft to rotate, so that the opening of the quadrangular pyramid filter box points to the inner cavity of the impurity storage cart outside the sedimentation box, so that the internal particulate impurities flow into the impurity storage cart under the action of gravity. However, in actual use, the device uses gravity to flow the internal particulate impurities into the impurity storage cart, so that some solid impurities are easily stuck in the filter holes of the filter box, making it impossible for them to flow into the storage cart with gravity, and then easily cause the filter holes of the filter box to be blocked, thereby affecting the filtering effect. Therefore, it is necessary to improve a filtering device for sewage treatment. Utility Model Content
