Along with the continuous increase of population, people use more and more water sources, sewage is a general term of water discharged in production and life, and polluted water caused by human production activities contains more pollutants and complex components, is not only difficult to purify in water, but also is difficult to treat.
The biological reaction tank is an important link in a sewage treatment system, sewage primarily precipitated by the grit chamber flows into the biological reaction tank, and the biological reaction tank treats the sewage by using activated sludge. In sewage treatment, activated sludge has strong capability of adsorbing and decomposing organic matters, inorganic matters or toxicants, is fully mixed with sewage being treated in a reaction tank under stirring and well diluted, and the organic matters, the inorganic matters and the toxicants in the sewage are degraded or adsorbed by aerobic microbial groups and anaerobic microbial groups in the sludge.
The existing plug-flow stirrer is often entangled by foreign matters such as fiber impurities or hair in sewage in the sewage treatment process, and the foreign matters such as the fiber impurities or the hair are wound on the blade, so that the power consumption of equipment operation is increased, the function is attenuated and the service life of the equipment is shortened if the foreign matters such as the fiber impurities or the hair cannot be cleaned in time. When the plug flow stirrer is lifted out of the reaction tank, the blade can carry the sludge out of the water surface, the sludge can be attached to the blade, if the blade is not cleaned in time, the blade can be corroded and damaged, the existing plug flow stirrer does not have the function of automatic cleaning, and the existing plug flow stirrer is cleaned manually, consumes time and labor, and increases labor cost.

When the extension blade 502 moves towards the outer side of the blade 5, the sleeve 506 rotates under the driving of the rotating shaft 503, at this time, the sleeve 506 releases the push-pull spring 505 outwards, when the push-pull spring 505 is released, the outer ring expands outwards, so that the outer ring pushes the filling plate 504, the filling plate 504 moves towards 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 that of the blade 5; the filling plate 504 of the partial extending blade 502 fills the width missing of the extending blade 502, and one end of the filling plate 504 of the non-extending blade 502 is pressed against the inner wall of the adjusting groove for sealing between the blade 5 and the extending blade 502, preventing sewage from entering the adjusting groove.
When the extension blade 502 needs to be retracted into the blade 5, the rotating shaft 503 rotates reversely, the sleeve 506 rotates reversely and winds up the push-pull spring 505, the thrust of the push-pull spring 505 on the filling plate 504 is reduced, and when the extension blade 502 moves towards the blade 5, due to the inclined arrangement of the filling plate 504, the blade 5 generates a certain extrusion force on the filling plate 504 through the extrusion slope surface, so that the filling plate 504 is extruded into the extension blade 502 by the blade 5, and the extension blade 502 is retracted quickly.
The working principle of the invention is as follows:
the stirring seat 4 and the blades 5 are placed in the sewage, the main motor 1 works under the control of the control system, and the blades 5 stir the sewage.
When the general sewage needs to be driven to flow, the rotating disc 405 works under the control of the control system, the linkage gear 404 is driven by the rotating disc 405 to rotate, the driven wheel 407 drives the worm 403 to rotate, and the worm 403 drives the rotating shaft 503 to rotate through the worm wheel 402. Due to F 1 And F 2 Is greater than F 3 When the rotating shaft 503 rotates, the rotating shaft 503 drives the sleeve seat 501 to move first, the inclination angle of the blade 5 is adjusted first, and when the sleeve seat 501 is blocked by the baffle, the rotating shaft 503 drives the sleeve 506 and the nut 507 to move.
The nut 507 is rotatably connected to the rotating shaft 503, the extension blade 502 is restricted by the adjustment groove and cannot rotate, and when the rotating shaft 503 rotates, the nut 507 moves on the rotating shaft 503, so that the extension blade 502 moves in the adjustment groove, and the extension blade 502 extends out of the blade 5.
When the extension blade 502 moves towards the outer side of the blade 5, the sleeve 506 rotates under the driving of the rotating shaft 503, at this time, the sleeve 506 releases the push-pull spring 505 outwards, when the push-pull spring 505 is released, the outer ring expands outwards, so that the outer ring pushes the filling plate 504, the filling plate 504 moves towards 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 of the partial extending extension blade 502 fills the width lack of the extension blade 502, and one end of the filling plate 504 which does not extend out of the extension blade 502 is pressed against the inner wall of the adjusting groove for sealing between the blade 5 and the extension blade 502, and preventing sewage from entering the adjusting groove.
When micro-mixing is required, the rotating shaft 503 is driven by the worm wheel 402 to rotate reversely, the rotating shaft 503 firstly drives the sleeve seat 501 to rotate reversely, and when the sleeve seat 501 is blocked by the baffle again, the rotating shaft 503 drives the sleeve 506 and the nut 507 to move reversely again. The sleeve 506 rotates reversely and rolls up the push-pull spring 505, the thrust of the push-pull spring 505 borne by the filling plate 504 is reduced, the extension blade 502 is retracted into the adjustment under the driving of the nut 507, when the extension blade 502 moves towards the inside of the blade 5, due to the inclined arrangement of the filling plate 504, the blade 5 generates a certain extrusion force on the filling plate 504 through the extrusion slope surface, 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 rotates along with the rotating shaft, so that the sleeve seat 501 and the cleaning shaft 401 are matched with each other to pull fiber impurities, the protective layer on the outer side of the cleaning knife 509 is extruded by the fiber impurities while the fiber impurities are pulled, the protective layer is compressed, the cutting edge of the cleaning knife 509 is exposed out of the protective layer, and the fiber impurities 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 pumps clean water into the cleaning shaft 401, the clean water is sprayed out of the cleaning holes 410, the water flow is blocked by the dispersing table 409, the water flow impacts on the dispersing table 409 to form a water curtain in the air, the water flow is dispersed, and therefore the cleaning area of the blades 5 is increased.
