[0002] The treatment of industrial wastewater is one of the important research directions in the environmental protection field, and its main purpose is to remove pollutants in wastewater through physical, chemical and biological methods, reduce the harm to the environment, and at the same time make the treated water quality meet the discharge or reuse standard. In the prior art, wastewater treatment usually involves multiple stages, such as sedimentation, filtration, oxidation and reduction, etc. However, due to the diverse types and complex composition of impurities in industrial wastewater, the traditional wastewater treatment equipment has certain limitations in the filtration and impurity removal link.

[0003] The conventional industrial wastewater filtration equipment usually adopts static filter screen or screen mesh to filter impurities. Such equipment is prone to the following problems during use:

[0004] 1. Impurity accumulation blockage: the surface of the filter screen is easily covered by particles or suspended solids in the sewage, causing water flow obstruction and reducing the filtration efficiency.

[0005] 2. Difficult to clean: the cleaning of the equipment often requires shutdown operation, which increases the maintenance difficulty of the equipment and affects the continuity of wastewater treatment.

[0006] 3. Incomplete collection of impurities: part of the impurities are easily attached to the surface of the filter screen or pass through the filter screen under the action of impact force, which cannot be effectively collected.

[0007] Based on the above problems, some improvement measures are proposed in the prior art, such as removing impurities by mechanical movement or increasing the area of the filter screen. However, these methods often increase the complexity and cost of the equipment, and there is still optimization space for the diversion and filtration effect of the sewage. SUMMARY

[0008] In view of the problems existing in the prior art, the purpose of the utility model is to provide an industrial wastewater treatment pool, which utilizes the diversion function of the water guide inclined plate and the rotating filtration characteristics of the impurity removal cage to effectively clean and collect impurities during sewage filtration, and at the same time realizes efficient filtration and recycling of sewage.

[0011] Further, a water guide inclined plate A is welded at one side of the top end of the water guide bin, and a water guide inclined plate B is welded at the other side of the top end of the water guide bin, the water guide inclined plate A and the water guide inclined plate B are used for guiding the sewage flowing out of the water inlet pipe, the sewage flowing out after being guided by the water guide inclined plate A and the water guide inclined plate B is used for driving the dedusting cage to rotate, and a water distribution tripod is welded on the surface of the water guide inclined plate A and is used for uniformly distributing the sewage, so that the sewage is prevented from excessively impacting the dedusting cage.

[0012] Further, inner frames are uniformly welded on the outer sides of the rotating shaft, and cage outer hoops are uniformly welded on the outer sides of the inner frames, and the cage outer hoops are used for filtering impurities in the sewage.

[0013] Further, scraping teeth are uniformly welded at one side of the top end of the collecting groove, one end of each scraping tooth is inserted into the gap between two adjacent cage outer hoops, and the scraping teeth are used for scraping off the impurities accumulated on the surfaces of the cage outer hoops.

[0014] Further, drain holes are uniformly arranged in the inner side of the side wall of the collecting groove, and the drain holes are used for draining the sewage adsorbed by the impurities.

[0015] Compared with the prior art, the industrial wastewater treatment tank has the following beneficial effects:

[0016] The industrial wastewater treatment tank provided by the application can effectively guide the flow of the sewage and slow down the impact force by arranging the water guide inclined plate A and the water guide inclined plate B.

[0017] The dedusting cage has a double-layer structure of the inner frame and the cage outer hoop, the dedusting cage is driven to rotate by the impact of the sewage, and the relative movement between the rotating dedusting cage and the scraping teeth can continuously remove the impurities accumulated on the surfaces of the cage outer hoops, thereby effectively avoiding the blockage problem caused by the accumulation of impurities in the traditional filtering equipment and improving the continuous operation efficiency of the equipment.
