The screw is divided into a threaded section and a smooth section, the threaded section is arranged at the rotating joint of the top end of the screw and the filtering component, then the smooth section is arranged on the screw, the stirring blade is fixedly connected to the smooth section, the screw and the stirring blade are integrally formed, and the stirring blade is driven to rotate and stir when the screw rotates, so that the flocculant and sewage are mixed in a filling way, and the oxidation effect is enhanced; a threaded section rotationally connected with the mud pushing assembly is arranged below the smooth section of the screw rod, and the length of the threaded section of the screw rod is required to meet the condition that the sleeve cannot mix She Pengzhuang when the mud pushing assembly moves up and down along the screw rod; when driven gear drives the screw rod and just reverses, it rotates rather than fixed connection's stirring She Tongsu, and push away mud subassembly and the filter component that is connected with the screw rod rotation along the corresponding screw thread up-and-down motion of screw rod, and then realize filter component and push away mud subassembly and improve sewage treatment's effect in step.
The stirring blade fixedly connected with the screw rod is used for stirring the suspended matters in the sewage and the flocculating agent uniformly, so that the suspended particles in the sewage are accelerated to be combined to form large particles, the precipitation is convenient, the stirring sewage can avoid solid impurity deposition and caking, further the water outlet and the pipeline are blocked, the solubility of oxygen can be increased, the metabolism of the sewage and microorganisms is promoted, and the effect of primary sewage treatment is achieved; generally, the rotation speed of stirring sewage mainly depends on the size and concentration of solid particles in the sewage, and the rotation speed needs to be adjusted according to actual conditions, and the rotation speed of stirring the sewage adopted by the application is 15-35 revolutions per minute, so that suspended particles in the sewage can be uniformly stirred with a flocculating agent, and meanwhile, the energy consumption is not wasted.
The driven gear is required to be arranged right above the water outlet, and a space is reserved between the driven gear and the water outlet, so that the water outlet cannot be covered, and the stirred sewage and impurities on the bottom surface of the pretreatment tank can be discharged from the water outlet; therefore, a bracket is arranged below the driven gear, the driven gear is placed on the bracket, the surface of the bracket is round, the round size is consistent with the size of the driven gear, the supporting legs of the bracket are respectively fixedly welded around the water outlet, the bracket is rotationally connected with the screw, the screw penetrates through the surface of the bracket, the bottom end of the screw is fixedly connected with a dredging block, the screw drives the dredging block to rotate in a pipeline which is communicated with the pretreatment tank and the sedimentation tank, the diameter of the dredging block cannot be larger than that of the pipeline, the friction force in the pipeline can be increased when the diameter of the dredging block is larger than that of the pipeline, the pipeline is damaged, meanwhile, the pipeline is blocked, and sewage is difficult to circulate normally; when the dredging block rotates in the pipeline, the dredging block can generate a vortex, the pollutants are extruded from the wall of the pipeline and are rolled into the vortex, and small particles suspended in the pipeline water can be easily rolled up by the dredging block due to the high-speed rotation of the vortex and pushed into the pipeline; however, when the diameter of the dredging block is too small, the dredging block cannot contact the inner wall of the pipeline when rotating, so that impurities on the pipeline cannot be scraped off, and the purpose of dredging the pipeline cannot be achieved. The dredging block can be a rectangular sheet, the screw drives the rectangular sheet to rotate in the pipeline, and the rectangular sheet is attached to the inner wall of the pipeline, so that impurities on the inner wall of the pipeline can be scraped to prevent blockage when the rectangular sheet rotates; the dredging block is cone, and when impurity in the sewage is too big, can't pass through the gap of pipeline and cone dredging block, consequently by the card in cone and pipeline, the cone rotates in the pipeline this moment, can grind the impurity, makes big impurity dispersion together become the little impurity that can pass through the space between cone ground and the pipeline to make the pipeline can not be blocked by impurity.
Because the power components rotate in the sewage, and various microorganisms and corrosive substances are contained in the sewage, and corrosion and damage are easily caused on the surfaces of the power components, the components such as the rotating shaft, the driving gear, the driven gear and the screw rod which work in the sewage for a long time are manufactured by materials which are not easy to rust, such as stainless steel, chrome alloy and the like; or the surface of the power assembly such as the gear can be subjected to anti-corrosion coating treatment, so that the power assembly can normally operate.
Preferably, the filter assembly comprises a screw cap, a filter plate, a sliding block and a sliding rail; the screw cap is rotationally connected with the screw rod of the power assembly in a threaded manner, so that when the driven gear drives the screw rod to rotate positively and negatively, the screw cap moves up and down along the screw rod at the thread position at the top of the screw rod, the upper end of the screw cap is conical, a sliding rail is arranged on the conical surface, the lower end of the screw cap is internally provided with a thread rotationally connected with the screw rod, the screw cap moves up and down along the screw rod, meanwhile, the screw cap is in sliding connection with the filter plate, the screw cap is provided with a sliding rail, and the sliding rail can enable the filter plate in sliding connection with the screw cap to move stably during movement and enable the filter plate to slide along the path of the sliding rail; the top of the pretreatment tank is used for carrying out preliminary filtration on sewage, a piece of filter plates are partially overlapped with each other to form a circle with the same size as the surface of the pretreatment tank and cover the pretreatment tank, the outer end of the filter plate is hinged with the upper end of the pretreatment tank, the filter plate can rotate around a hinge point at the upper end of the pretreatment tank, and the other end of the filter plate is fixedly connected with a sliding block and a screw cap in a sliding way; so that large impurities in the sewage are filtered above the filter sheet by the filter sheet; when the screw cover moves upwards, the filter disc is driven to move upwards, at the moment, the filter disc is changed into an inclined plane from the plane, when the filter disc is the plane, massive impurities are attached to the surface of the filter disc, and when the filter disc is changed into the inclined plane, the impurities can slide down from the surface of the filter disc, so that the effect of automatically cleaning the filter disc is realized.
