Working principle and structure
The series sand suction machine, as shown in Figure 1 and Figure 2, consists of a main beam, a driving device, a submersible sewage pump, a skimming device, a track, and a control box.
The sand suction machine automatically runs back and forth on the steel rail placed on the top of the pool according to the set cycle, lifting and discharging the sand water mixture at the bottom of the pool to the collection channel at the edge of the pool. When traveling along the water flow, the skimming plate descends to scrape off the floating slag and sends it to the slag tank at the end of the pool. When traveling in the opposite direction, the skimming plate lifts and leaves the liquid surface to prevent the floating slag from reversing (reverse skimming can also be carried out according to process requirements).

characteristic
Adopting a submersible non clogging pump to lift and transport sand water mixture is simpler than an air lift pump and can avoid the noise generated during the operation of the air compressor, while also consuming less energy.

purpose
The sand suction machine is used in the sedimentation tank and aeration sedimentation tank of sewage treatment plants to lift and transport the mixture of heavy particles such as sand and coal slag settled on the bottom of the tank and sewage to the channel connected to the sand water separator.
