Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment equipment technical field especially is continuous sewage treatment device. BACKGROUND

[0002] With the continuous advancement of industrialization and urbanization, its pace is increasingly accelerated, and it is accompanied by the sharp rise of sewage production. Under this background, the importance of sewage treatment is increasingly prominent, it is not only the key defense line of environmental quality, but also the key link to realize water resource recycling, maintain ecological balance and stability, and plays an irreplaceable important role for the sustainable development of society.

[0003] The patent with the publication number CN211585606U discloses a continuous sewage treatment device, which sets an interception cylinder and a collecting bucket in the sewage collection box, connects an interception ring between the upper ends of the interception cylinder and the collecting bucket, rotates a mud removal plate below the interception cylinder and sets a collection chamber, and sets the outlet of the sewage on the upper end of the side wall of the collection chamber. When the sewage enters the sewage collection box, it first passes through the interception cylinder, the interception ring and the collecting bucket. The mesh surface structure of the interception ring allows the components in the sewage except the large-volume garbage and impurities to pass through, and the large-volume garbage and impurities are intercepted by the interception net and the collecting bucket, and finally fall into the collecting bucket for unified collection and treatment. The mud removal plate below the interception cylinder can make the sludge deposited on its upper end surface, and the sewage continues to flow down along the water permeable holes of the mud removal plate and enters the collection chamber below, and then enters the sewage pressurizing pump along the pipeline and is transported to the sewage treatment box. Among them, the collection chamber can further deposit the sludge that cannot be treated by the mud removal plate, and when the sludge needs to be removed, only the mud removal plate needs to be driven to rotate by the driving motor, the sewage outlet needs to be opened, and the sludge needs to be flushed to the below under the water flow, and finally needs to be cleaned out uniformly from the sewage outlet.

[0004] However, in the existing technical system, there are some problems in the sewage filtration link that need to be solved. Specifically, the sewage filtration is mostly conducted in a single direction, such as in the horizontal direction or the vertical direction, and the filtration structure commonly used is mostly fixed. This design exposes obvious defects in actual operation. Because the filtration structure is fixed, the impurities after filtration are easily attached to its surface. With the passage of time, the impurities accumulate more and more, gradually causing the blockage of the filtration structure. Once the filtration structure is blocked, not only will the filtration efficiency be significantly reduced, the time cost and energy consumption of sewage treatment will be increased, but also the subsequent treatment process may be linked, affecting the stable operation of the entire sewage treatment system, and seriously restricting the improvement of sewage treatment effect and the further development of the sewage treatment industry.

In the horizontal direction of support frame 1, fixedly connected with an inlet pipe 2, and the lateral wall of inlet pipe 2 is distributed with a plurality of water outlets 3. Sewage enters the whole treatment system through inlet pipe 2, and the design of water outlet 3 can make sewage evenly distribute in subsequent filtration process.

[0040] On the lateral side of inlet pipe 2, a plurality of filter cartridges 4 are coaxially rotatably connected, and the filter holes 5 of these filter cartridges 4 gradually decrease in size from inside to outside. This design enables sewage to be filtered through multiple stages, gradually removing impurities of different particle sizes, thereby achieving better filtration results. For example, the innermost filter cartridge 4 can be used to filter larger particles, while the filter cartridge 4 with smaller outer diameter can be used to filter smaller particles, achieving fine filtration of impurities in the sewage.

[0041] The power assembly is used to drive the rotation of the plurality of filter cartridges 4, providing power for the rotation of the filter cartridges 4, ensuring continuous rotation of the filter cartridges 4, and ensuring the continuity of the sewage filtration process.
