Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A high-efficiency anti-floating slag device for a sedimentation tank is arranged in the sedimentation tank 1, as shown in figure 1, the sedimentation tank 1 is communicated with a water inlet pipe 7 and a water outlet pipe 9, wherein the water inlet pipe 7 is used for introducing sewage, the water inlet pipe 7 extends into the sedimentation tank 1 and is communicated with a water distribution central barrel 6, and the water distribution central barrel 6 enables the sewage to uniformly flow into the sedimentation tank; a sludge discharge pipe 8 is arranged at the bottom of the sedimentation tank 1, and a valve is arranged on the sludge discharge pipe 8 for facilitating the control of the opening or closing state of the sludge discharge pipe 8; sludge in the sewage can be deposited to the bottom of the sedimentation tank 1 under the action of gravity, and the valve on the sludge discharge pipe 8 is opened, so that the sludge can be discharged. The water level of the water outlet pipe 9 is higher than the water level of the water inlet pipe 7, and the upper layer of clear water is discharged through the water outlet pipe 9 when reaching the height of the water outlet pipe 9. However, scum generated by various reasons can float upwards during sedimentation treatment, and in order to solve the floating problem of the scum, two stages of scum blocking mechanisms, namely a first-stage scum blocking mechanism and a second-stage scum blocking mechanism, are designed in the sedimentation tank.
One-level pushing off the slag mechanism in the top of inlet tube 7, realizes that first-level pushing off the slag is handled, still as shown in fig. 1, one-level pushing off the slag mechanism includes guide plate 5, row's sediment cover 4 and row's sediment pipe 3, and wherein, guide plate 5 uses with row's sediment cover 4 cooperation, intercepts the dross and collects, has: the guide plate 5 is arranged around the inner wall of the sedimentation tank 1 and inclines upwards, the slag discharge cover 4 is positioned above the guide plate 5, the plate body of the slag discharge cover 4 inclines downwards, the plate body of the slag discharge cover 4 is superposed with the projection part of the guide plate 5, so that the scum guided by the guide plate 5 is collected at the slag discharge cover 4, the slag discharge cover 3 is communicated with the scum pipe 3, the scum pipe 3 extends out of the sedimentation tank 1, and finally the collected scum is discharged through the scum pipe 3; usually, the deflector 5 is parallel to the plate body of the slag discharge cover 4, so that the scum moves upwards along an inclined plane, and clear water is allowed to flow out of the gap between the deflector 5 and the slag discharge cover 3 and continuously floats upwards. In addition, in order to facilitate the control of the opening or closing state of the slag discharging pipe 3, a valve is also installed on the slag discharging pipe 3.
