Compared with the prior art, the present invention has the following advantages:
1. material successively passes through precompressed zone and pressed zone, squeeze pressure suffered by sludge is gradually increased, the roller of precompressed zone
The pressure-applying unit of body quantity and pressed zone can be arranged with modularization, can adjust precompressed zone roll body and pressed zone according to sludge quality
The quantity of pressure-applying unit, the mode of equipment echelon pressurization is more rationally flexible, to the more adaptable of sludge.
2. the strainer tension of precompressed zone and the squeeze pressure of pressed zone are settable constant, pressure is easy to adjust, can avoid into
Expect that material properties fluctuates the influence to equipment, the stability of equipment is higher.
3. material water ratio has decreased, and the subsequent difficulty being further dehydrated has by the preliminary hydro-extraction of precompressed zone
Increased, the subsequent pressed zone of precompressed zone, in addition to increasing squeeze pressure, also add the upper lining band with the water storage function that absorbs water,
While mechanical expression squeezes, upper lining band is stripped of portion of water by suction-operated, reaches filter cake upper and lower surface simultaneously
The effect of dehydration, dehydration efficiency are higher.
4. the water suction water storage material of lining band also plays effect of the buffering pressure-applying unit to strainer in addition to absorbing moisture on
Power, the supporting role with lining band at present make strainer avoid strainer deflection excessive while receiving strong force squeezing, these measures
The service life of strainer can be extended well.
