Detailed Description
The anti-overload device for the sewage tank sludge pump in the white carbon black production of the present invention is further described in detail with reference to the accompanying drawings and the specific implementation mode.
As shown in fig. 1, the overload prevention device for the sludge pump in the sewage tank in the production of white carbon black of the utility model comprises a sewage sedimentation tank 3, a movable sludge pump 4, a transition groove 6 with a stirring device 7, a pressure pump 8 and a filter pressing plate frame 14; the sewage sedimentation tank 3 comprises a water inlet channel arranged at the left side with the sewage inlet 2, a middle four-stage sedimentation tank and a water outlet channel arranged at the right side with the sewage tank outlet 11; an inlet pipe 1 of a sludge pump of the movable sludge pump 4 extends into the primary sedimentation tank, and an outlet pipe is connected to a transition tank 6; the transition groove 6 is provided with an overflow port and is connected to a secondary sedimentation tank through an overflow pipe 5, one path of the outlet at the bottom of the transition groove 6 is connected with a booster pump inlet pipe 9, and the other path is connected with a sewage discharge pipe 10; an outlet pipeline of the booster pump 8 is connected to a filter pressing plate frame 14 through a pressure gauge 13, and a filter pressing plate frame water outlet pipe 12 is connected to a final-stage sedimentation tank.
Sewage from production enters a sewage tank 3 through a sewage inlet 2, and is discharged from a sewage tank outlet 11 after reaching the standard through fractional precipitation and neutralization treatment; the settled sludge and slurry are pumped into a transition tank 6 from a movable sludge pump 4 through a sludge pump inlet pipe 1, and if excessive slurry exists, the sludge and the slurry return to a sewage pool through an overflow pipe 5; under the action of the stirring device 7, the more homogenized sludge slurry enters a booster pump 8 through a booster pump inlet pipe 9 and is pumped into a filter pressing plate frame 14 with a pressure gauge 13, the filtered clean filtrate enters a front-stage tank, namely a final-stage sedimentation tank, of a sewage tank outlet 11 from a filter pressing plate frame water outlet pipe 12 and then flows through a water outlet channel for neutralization treatment; the transition tank 6 is periodically cleaned and discharged through a sewage discharge pipe 10. Because the movable sludge pump 4 directly pumps the slurry and the block-shaped sludge which are flushed by high-pressure water into the transition slot 6, the required lift is low, the load of the motor cannot be quickly increased to exceed the limit even if the motor is blocked, the motor protection action can work in time, and the condition that the motor is damaged due to overload is avoided. The transition tank 6 can well homogenize the slurry-containing water and the block-shaped mud into a uniform liquid fluid under the action of the stirring device 7, thereby ensuring the stable operation of the pressure pump 8 and ensuring that the mud is easy to disperse and filter when entering the filter press plate frame 14.
