Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection water treatment, and specifically refers to a high-efficiency sedimentation and filtering tower. Background Art

[0002] Sedimentation and filtration towers are devices used for sewage and wastewater treatment. Traditional sedimentation and filtration towers usually use physical methods to remove impurities from the water through filter materials of various pore sizes, using adsorption or blocking methods, and allowing impurities with larger specific gravity to settle to the bottom of the water to achieve sewage and wastewater treatment.

[0003] Existing sewage filtration devices, such as a sewage filtration device for environmentally friendly water treatment disclosed in application number CN202020267436.8, realizes multiple filtration of sewage through the setting of a first filter net, a second filter net, a filter sand bag and an activated carbon bag, greatly improving the filtration efficiency of sewage. It adopts a snap-on installation method to facilitate the cleaning of the device. At the same time, through the setting of a stirring motor, a stirring shaft and a stirring blade, the dissolution of the precipitant in the sedimentation box is accelerated, so that the sewage is quickly precipitated and the sedimentation time is shortened.

[0004] However, in actual use, sewage and wastewater will contain more solid impurities. Although filters are used to intercept them, the filtered solid impurities cannot be discharged in time, resulting in a short service life of the filter. Frequent replacement and cleaning are required, resulting in low filtration efficiency and increased cost of use. In addition, the use of motor-driven stirring has a complex overall structure and high cost. In particular, during sedimentation, as the sewage filtered from the upper end continues to flow in, the sewage in the sedimentation tank will fluctuate greatly, thereby affecting the precipitation of impurities with a larger specific gravity. For this reason, we propose a high-efficiency sedimentation filter tower to solve the above problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a high-efficiency sedimentation filter tower, which effectively solves the problem that the existing high-efficiency sedimentation filter tower cannot discharge the filtered solid impurities in time during use, thereby resulting in a short service life of the filter screen and high maintenance costs. It also solves the problem of complex stirring structure and solves the problem of large fluctuations and difficult sedimentation of sewage in the sedimentation box.
