The invention provides a tank bottom
sludge discharging device for an oilfield
sedimentation tank. A tank body is provided with a
sludge bearing bottom plate and a
sludge collection chamber, the sludge collection chamber is connected with a sludge discharging pump, a
sedimentation tank center
pipe is connected with a center support connected with a driven gear, the driven gear is in meshed connection with a driving gear, a shaft of the driving gear is connected with a gear motor through a
coupling, the gear motor is fixedly connected with a sleeving
pipe outside the tank top, four groups of frameworks are fixedly and radially connected around a shaft of the driven gear, bottoms of the frameworks are connected with sludge scraping plates.
Sludge is discharged through a tank bottom sludge removal
system, the problem of sludge
sedimentation at the tank bottom is solved, sludge is discharged thoroughly, no dead zone exists,
water resources are saved, the device adopts a mechanical structure and is stable in operation and reliable in performance, a mechanical part of the tank bottom of the sedimentation tank is free of
welding structures, a bolt fastening connection method is adopted, an ultrasonic interface sensor is arranged, the automatic tank bottom sludge removal
system sets parameters such as the starting frequency, the working time and the like of the device through programs, sludge collection and sludge discharging are controlled automatically and regularly through the programs, and full-automatic operation of the
system is realized.
