As shown in fig. 5, a first comparative example, in which another embodiment of the present invention is: a detection light curtain 29 is fixed inside the sedimentation tank 1, a sliding rail 30 is arranged outside the detection light curtain 29, a lifting block 31 is connected outside the sliding rail 30 in a sliding manner, a fastening frame 32 is fixed on one side, away from the sedimentation tank 1, of the lifting block 31, an opening plate 33 is fixed inside the fastening frame 32, and a drain pipe 28 is connected to the bottom end of the sedimentation tank 1 in a penetrating manner; the during operation, after sewage flocculation accomplishes, solid precipitate can deposit in the bottom of gunbarrel 1, start to detect light curtain 29 this moment and make its operation, shelter from through the precipitate to detecting light curtain 29, can effectually judge the parting line of precipitate and supernatant, detect light curtain 29 this moment and just can be to system's signals, thereby drive elevator block 31 slides on sliding rail 30, thereby elevator block 31 slides and drives fastening frame 32 and slides, thereby fastening frame 32 slides and drives the motion of open-close plate 33, lower surface and this parting line until open-close plate 33 are the coplanar, open-close plate 33 afterwards makes supernatant and precipitate separation, open blow off pipe 28 afterwards and discharge the precipitate, and the supernatant alright can pass through the water pump and take out, so just reached the effect that can accurately separate supernatant and precipitate.
According to the working principle, before use, the flocculating agent is required to be added into clear water according to a ratio of ten to be mixed, the mixed liquefied flocculating agent flows into the material supplementing pipe 17 through the storage bin and then is injected into the liquid storage column 4 through the material supplementing nozzle 18, so that the flocculating agent is supplemented for the liquid storage column 4; under normal conditions, the extrusion plug 5 can seal and block the liquid storage column 4 to prevent the flocculating agent from entering one side of the protective shell 11, and once the extrusion plug 5 is damaged, the flocculating agent enters one side of the protective shell 11, the protective shell 11 can effectively protect the servo driving assembly 13 to prevent the flocculating agent from entering water and being damaged, and the sealing ring 12 further improves the sealing effect; after sewage is completely injected into the settling tank 1, the power supply of the servo driving assembly 13 is started to operate so as to drive the coupler 10 to rotate, the coupler 10 rotates to drive the rotating screw 8 to rotate, the sliding ring 7 can slide along the rotating screw 8 towards the direction far away from the servo driving assembly 13 in the rotating process of the rotating screw 8, the sliding ring 7 moves to push the connecting rod 6 to move, the connecting rod 6 moves to push the extrusion plug 5 to slide in the liquid storage column 4, so that the flocculant in the liquid storage column 4 is extruded, the pressure on the flocculant is increased, the flocculant can be sprayed out finally, the sprayed flocculant is injected into the sewage, a thrust can be simultaneously applied to the liquid storage column 4 in the process, the thrust acts on the extension frame 3 through the liquid storage column 4, the support rod 2 is driven to rotate through the extension frame 3, and the sewage can be stirred while the flocculant is sprayed, meanwhile, the flocculating agent is sprayed in such a way, so that the flocculating agent can be uniformly dispersed in the settling tank 1, the mixing degree of the flocculating agent and the sewage is improved, the sewage can be stirred in the rotating process of the liquid storage column 4, the using effect of the flocculating agent is further improved, the effect that the flocculating agent can be rotatably sprayed without stirring the sewage from the outside is achieved, meanwhile, the number of rotating turns of the rotating screw 8 can be accurately controlled through controlling the servo driving assembly 13, the spraying amount of the flocculating agent is further controlled, and the effect that the flocculating agent can be quantitatively sprayed is achieved;
in the process, when the connecting rod 6 slides along with the rotating screw 8, the connecting rod 6 can reach the maximum stroke and cannot move continuously after sliding to be in contact with the limiting ring 9, the connecting rod 6 is limited by the limiting ring 9, the extrusion plug 5 can be in contact with the limiting ring 9 in the process of resetting the equipment, and the abrasion of the extrusion plug 5 in contact with the limiting ring 9 can be effectively reduced through the rubber pad outside the limiting ring 9; in the process of spraying the flocculating agent in the liquid storage column 4, the flocculating agent is firstly injected into the contraction ring 14 so as to pressurize the flocculating agent for the first time, then the flocculating agent is sprayed out through the feeding spray head 15 so as to pressurize the flocculating agent for the second time, and the pressure valve 16 in the feeding spray head 15 is not opened before the flocculating agent reaches the set pressure, so that the kinetic energy generated when the flocculating agent is sprayed out is effectively ensured to be enough to support the equipment to rotate; in the process of spraying the flocculating agent by rotating the equipment, the liquid storage column 4 can simultaneously drive the mounting frame 20 to rotate, and the mounting frame 20 rotates to drive the balancing weight 21 to rotate, so that after the flocculating agent spraying is stopped, the inertial force borne by the balancing weight 21 can still drive the equipment to continuously rotate for a period of time to stir the sewage and the flocculating agent, and the effect of flocculating the sewage is improved; in the process of rotation of the equipment, the power supply of the electric heating shell 19 is synchronously started to start heating, so that the temperature outside the electric heating shell 19 rises, and flocculated sediments are not easy to adhere to the outer surface of the equipment, thereby causing unsmooth operation of the equipment;
in the rotating process of the equipment, the mounting frame 20 can simultaneously drive the rotating magnet 22 to rotate, in the rotating process of the rotating magnet 22, an attractive force can be applied to the sliding magnet 26, the attractive force can enable the sliding magnet 26 to stretch the reset spring 24 and then push the scraper knife 27 to move, the scraper knife 27 slides on the inner wall of the sedimentation tank 1, the scraper knife 27 can clean sediments attached to the inner wall of the sedimentation tank 1 in the sliding process, and therefore the effect of automatically cleaning the sediments on the inner wall is achieved; the sliding magnet 26 can simultaneously stretch the telescopic shell 25 to extend and retract in the sliding process, the telescopic shell 25 can effectively block external sewage and protect the internal structure of the telescopic shell, and meanwhile, the telescopic shell 25 can separate sediments attached to the outside of the telescopic shell 25 in the extending and retracting process;
after sewage flocculation accomplishes, the solid precipitate can deposit in the bottom of gunbarrel 1, start to detect light curtain 29 this moment and make its operation, shelter from through the precipitate to detecting light curtain 29, can effectually judge the parting line of precipitate and supernatant, detect light curtain 29 this moment and just can be to system's signals, thereby drive elevator block 31 slides on sliding rail 30, thereby elevator block 31 slides and drives fastening frame 32 and slide, thereby fastening frame 32 slides and drives the motion of split plate 33, lower surface and this parting line of split plate 33 are the coplanar, split plate 33 is closed afterwards makes supernatant and precipitate separation, open blow off pipe 28 afterwards and discharge the precipitate, and the supernatant alright is taken out through the water pump, so just reached the effect that can accurately separate supernatant and precipitate.
