Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a stable water circulation filtering device. Background Art

[0002] A water circulation filtration device is a device that can remove, intercept and filter impurities and foreign matter in water. For example, when environmentally treating industrial wastewater or river water, a water circulation filtration device is used, which has a significant effect on environmental protection and pollution reduction.

[0003] When using a traditional water circulation filtration device, the equipment will be debugged through the control box on the filter tank. Then the water will enter the filter tank from the pipe, and then be processed by the equipment in the filter tank. The treated water will go out from the outlet pipe under the treatment tank, thereby realizing the circulation filtration of the water quality.

[0004] During the use of the existing filter tank, the process of disassembling and replacing the filter element inside it is rather cumbersome, and when the filter tank is placed on the ground, the support legs are fixedly connected to the ground with bolts to prevent the filter tank from shaking and tipping over, thereby ensuring the stable use of the filter tank. However, when fixing with bolts, bolt-connected holes will appear on the ground, causing damage to the ground, and it is not convenient to move the filter tank, affecting the convenience of using the filter tank. Based on this, the present application proposes a stable water quality circulation filtration device to solve the above problems. Utility Model Content
