Along with the continuous growth of population, people use more and more water sources, sewage is a generic term for water discharged in production and life, and polluted water caused by human production activities contains more pollutants and has complex components, so that the water is not easy to purify and difficult to treat.
The biological reaction tank is an important link in a sewage treatment system, sewage which is preliminarily precipitated by the grit chamber flows into the biological reaction tank, and the biological reaction tank utilizes activated sludge to treat the sewage. In sewage treatment, the activated sludge has strong capability of adsorbing and decomposing organic matters, inorganic matters or poison, is fully mixed with sewage being treated in a reaction tank under stirring and is well diluted, and the organic matters, inorganic matters and poison in the sewage are degraded or adsorbed by aerobic microorganism groups and anaerobic microorganism groups in the sludge.
The existing plug flow stirrer is often entangled by foreign matters such as fiber sundries or hair in sewage in the sewage treatment process, and if the foreign matters such as the fiber sundries or the hair are entangled on the blades, the running power consumption of the equipment is increased, the functions are attenuated and the service life of the equipment is reduced because the foreign matters such as the fiber sundries or the hair cannot be cleaned timely. When putting forward plug flow agitator out the reaction tank, can bring the mud out the surface of water on its blade, mud also can adhere to on the blade, if not in time clear up, can cause the corruption and the damage of blade, and current plug flow agitator does not possess the function of automatic clearance, when the clearance, all is manual cleaning, and consuming time and consuming power increases the cost of labor.

The nut 507 is rotatably connected with the rotating shaft 503, the extension blade 502 is limited by the adjusting groove and cannot rotate, when the rotating shaft 503 rotates, the nut 507 moves on the rotating shaft 503, and then the extension blade 502 moves in the adjusting groove, so that the extension blade 502 extends out of the blade 5.
When the extension blade 502 moves to the outer side of the blade 5, the sleeve 506 rotates under the drive of the rotating shaft 503, at this time, the sleeve 506 outwards releases the push-pull spring 505, and when the push-pull spring 505 is released, the outer ring outwards expands, so that the outer ring pushes the filling plate 504, the filling plate 504 moves to the outer side of the extension blade 502, the filling plate 504 fills the missing width of the extension blade 502, and the width of the extension blade 502 is the same as the width of the blade 5; the filling plate 504 which partially extends out of the extending blade 502 fills the width defect of the extending blade 502, and one end of the filling plate 504 which does not extend out of the extending blade 502 abuts against the inner wall of the regulating tank for sealing between the blade 5 and the extending blade 502, so that sewage is prevented from entering the regulating tank.
When micro-mixing is needed, the rotating shaft 503 is reversely rotated under the driving of the worm wheel 402, the rotating shaft 503 drives the sleeve seat 501 to reversely rotate, and after the sleeve seat 501 is blocked by the baffle plate again, the rotating shaft 503 drives the sleeve 506 and the nut 507 to reversely move again. The sleeve 506 is reversed and the push-pull spring 505 is wound, the push force of the push-pull spring 505 received by the filling plate 504 is reduced, the extension blade 502 is retracted into the adjustment under the drive of the nut 507, when the extension blade 502 moves towards the inside of the blade 5, the blade 5 generates a certain extrusion force to the filling plate 504 by extruding the sloping surface due to the inclined arrangement of the filling plate 504, so that the filling plate 504 is extruded into the extension blade 502 by the blade 5, and the extension blade 502 is rapidly retracted.
When the rotating shaft 503 drives the blade 5 to rotate, the sleeve seat 501 also rotates along with the blade 5, so that the sleeve seat 501 and the cleaning shaft 401 are matched with each other to pull the fiber sundries, the protective layer on the outer side of the cleaning knife 509 is extruded by the fiber sundries while the fiber sundries are pulled, the protective layer is compressed, the cutting edge of the cleaning knife 509 exposes out of the protective layer, and the fiber sundries are cut off by the cutting edge in the rotating process of the sleeve seat 501.
When the blades 5 and the stirring seat 4 need to be cleaned, the water supply system infuses clean water into the cleaning shaft 401, the clean water is sprayed out from the cleaning holes 410, water flow is blocked by the dispersing table 409, and the water flow is impacted on the dispersing table 409 to form a water curtain in the air, so that the water flow is dispersed, and the cleaning area of the blades 5 is increased.
