Embodiment Construction
[0021] A method for dehydrating a water-containing material, comprising wrapping and extruding the water-containing material, characterized in that the wrapping of the water-containing material is to wrap the liquid-containing material by the circulation filter cloth 4 of the water-containing material dehydration device so that the cross-section is triangular or Rectangular elongated bag-type continuous inclusions; the extrusion dehydration is carried out under the rolling extrusion of the upper chain rail 6 and the lower chain rail 8 of the hydrous material dehydration device, and is unfolded by the unpacker 11 after dehydration The circulating filter cloth 4 of wrapping, the material after dehydration is unloaded, circulates
[0022] The ring filter cloth 4 runs continuously and enters the next cycle process.
[0023] The gap between the upper chain rail 6 and the lower chain rail 8 of the hydrous material dehydration device is adjusted by the adjusting screw 7, and the gap ...
