Sand Separator / Hydrocyclone

Ladda ned datablad Video Sand Separator / Hydrocyclone

Application

Sand separators are used for heavy contaminant separation from suspensions. Wire and pieces of metal sheet, in particular small, grainsize particles, such as glass and grit, will be separated.

Construction

Hydrocyclone

  • Headpiece including inlet and outlet pipes provided with wear-resistant inserts
  • Separating cone with wear-resistant insert
  • Intermediate pipe

Dirt trap

  • Two pneumatically operated special gate valves
  • Flush valve

Sand classifier

  • Box
  • Spiral conveyor

Operation

The suspension entering the head-piece in tangential direction is subjected to high centrifugal acceleration based on the hydrocyclone principle. Under the effect of this, contaminants are flung to the wall of the separating cone, from where they sink into the dirt trap through an intermediate pipe, followed by the clean suspension being discharged from the headpiece of the grit separator in axial direction.

Two looking glasses have been provided in the dirt trap for checking the sinking process.

Heavy contaminants, such as adhering fibrous particles, are removed by the addition of backflow water to the dirt trap.

Adjustable operating cycles of gate valves and dirt trap guarantee high adaptability to any level of contamination in the suspension.
