Description

Technical Field

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

[0002] Sewage refers to wastewater containing harmful substances, solid impurities and garbage generated in people's daily life or industrial production. Sewage has two paths after it is generated. The first is to be used as tap water again after multi-stage treatment, deodorization, disinfection and sterilization, while the other path is to be discharged into natural water bodies after simple treatment to remove harmful substances and impurities contained in the sewage, so as to avoid pollution of natural water bodies.

[0003] The current sewage treatment methods mainly include physical methods, chemical methods and biological methods. Among them, the physical method mainly removes impurities in sewage through filtration, precipitation and adsorption, and filtration is the most commonly used physical method. When sewage with solid impurities passes through the filter, the solid impurities can be intercepted by the filter to achieve solid-liquid separation. The sewage after the solid impurities are removed will go to the next step for deep sewage treatment. In the current sewage filtration devices, the filter nets are mostly fixed. After long-term sewage treatment, solid impurities will be blocked and accumulated on the filter net, resulting in a decrease in water flow and a decrease in sewage treatment efficiency. When cleaning the filter net, the sewage filtration device needs to be stopped, resulting in an interruption in the sewage treatment process.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0026] A plurality of groups of slag-cleaning rods 5 are fixed on the inner wall of the inner conical filter cartridge 4 along its circumferential direction, and the slag-cleaning rods 5 of each group are spaced apart along the length direction of the inner conical filter cartridge 4; a conveying mechanism is installed on the frame 1, and the conveying mechanism includes a conveyor belt 6, an active roller 10 and a driven roller 11, and the active roller 10 and the driven roller 11 are rotatably installed on the frame 1, and the conveyor belt 6 is connected with the active roller 10 and the driven roller 11, and the active roller 10 and the driven roller 11 are connected through the conveyor belt 6, and the conveyor belt 6 passes through the inner cavity of the inner conical filter cartridge 4. While the inner conical filter drum 4 rotates to discharge impurities, the slag-lifting rod 5 will scoop up some impurities, and when it rotates to the upper part of the inner conical filter drum 4, under the action of gravity, the slag-lifting rod 5 will guide the impurities to the conveyor belt 6. By driving the active roller 10 to rotate, the conveyor belt 6 can be driven to move, so that the conveyor belt 6 outputs the impurities from the inner conical filter drum 4, which can achieve rapid slag discharge and avoid impurity blockage in the inner conical filter drum 4 when there are many impurities or the impurity fluidity is poor, thereby improving the impurity discharge efficiency and the sewage treatment effect.

[0027] In a preferred embodiment, in order to prevent impurities from being stuck between adjacent slag-scraping rods 5, each group of slag-scraping rods 5 is arranged to be equidistantly distributed along the length direction of the inner conical filter cartridge 4.
