,r. Extra long gravity dehydration zone
,r>
,r>After chemical The sludge after purple condensation treatment is evenly distributed on the mesh belt through the distributor. A large amount of free water will be removed at this stage. Due to the design of sufficient length, it has a greater ability to withstand fluctuations in the feed sludge. , due to the appropriate tilt angle designed in this area, the free water in the upper part of the mud layer is promoted to flow back, which prolongs the residence time of the treatment medium in the gravity area. The gravity dewatering area is equipped with a multi-stage rake to sequentially remove the mud layer on the filter belt. Stir and plow into multiple water filtration paths to speed up the filtration speed of free water in the mud layer and ensure that as much free water as possible is filtered out. The multi-stage rake provided in the gravity dehydration section of this machine can be used to adjust the sludge properties according to different sludge properties. and characteristics, adjust the configuration randomly.

,r, inclined ultra-long wedge-shaped area
,r>
,r>The ultra-long inclined wedge-shaped area is the Another feature of the company's latest design is that the sludge passing through the gravity dewatering zone must be fully pre-pressed and dehydrated before entering the extrusion zone. Otherwise, the viscous sludge will be suddenly pressurized in the extrusion zone. The mud is extruded from both sides of the filter belt and leaks out. The wedge-shaped area slowly clamps the sludge unloaded in the gravity area to form an interlayer in the wedge-shaped area. The pre-pressure is gradually and slowly increased to remove the residual free water in the mud layer. As the upper and lower mesh belts advance slowly, the distance between the upper and lower mesh belts gradually decreases, the mud layer in the middle gradually hardens, and the ability to withstand external pressure gradually increases. The wedge-shaped area must ensure that the preload increases. The large speed is coordinated with the speed of filter cake formation to ensure that the pre-pressed filter cake can be well filtered into the high-pressure zone. The newly designed inclined wedge-shaped zone can adapt to sewage with different moisture contents, and the effect is particularly significant.< br/> ,r>
,r. Sludge extrusion and dehydration area
,r>
,r>This area is equipped with many squeeze rollers with decreasing roller diameters. The first The porous and ultra-large roller diameter pre-pressed filter roller improves the smooth transition of the filter cake from the low-pressure area into the decreasing high-pressure area of the roller diameter. When the upper and lower mesh belts pass through the shaped path formed by the interlacing of multiple rollers, due to the two The upper and lower positions of the filter belt alternate sequentially, generating shear force on the clamped mud cake, squeezing and filtering out most of the water remaining in the sludge. The squeeze rollers in this area are compactly arranged, and the roller distance is minimized to ensure The two filter belts will not pleat due to uneven stress.

,r. Correction and tightening of the filter belt
,r>
, r>The operation of the filter belt must be kept as symmetrical as possible in the middle of each roller. This machine adopts sensitive pneumatic component sensor detection and control. When the filter belt is laterally deflected, the deflection-correcting cylinder drives one end of the deflection-correcting roller forward or backward, thereby ensuring The maximum offset of the upper and lower mesh belts does not exceed. Sensitive pneumatic component sensors are used for detection and control. The detection angle and buffering are large, so that the two mesh belts and the running process are always monitored, and the control position is accurate. It completely solves the problem of the conventional correction switch slipping off the sliding arm or chute of the travel switch when it suddenly comes into contact with the mesh belt or the pressure is too high.
