Circulating device for wastewater purification

The utility model discloses a circulating device for wastewater purification, which comprises a machine body, an anti-blocking component is detachably mounted on the surface of the machine body, and a movable water inlet pipe is movably mounted on the surface of the anti-blocking component. According to the scheme, the anti-blocking assembly is arranged, before a water source enters the circulating device, impurity particles contained in the water source can be blocked outside the circulating device by the filter plate installed in the communicating pipe, so that impurities can be reserved in the communicating pipe, and when the impurity particles reserved in the anti-blocking pipe need to be cleaned, the anti-blocking assembly is arranged on the communicating pipe. According to the anti-blocking device, firstly, movable grooves are moved towards the two sides of a first fixing plate correspondingly, so that the movable grooves can be far away from the surface of a sealing ring, fixing blocks can be separated
