Description
slow pressure on the sludge, and the sludge gradually thickens and decreases in fluidity, and then transfers to the pressing zone.In the pressing zone, the sludge was affected by the shear force generated by the increasing extrusion pressure and the alternating upper and lower positions of the two filter belts. Most of the free water and interstitial water remaining in the sludge were filtered out, and the sludge became the flaky filter cake with low moisture content.The upper and lower filter belts are separated by the unloading roller, and the filter cake is scraped off by the scraper according to the change of the curvature of the filter belt, so as to realize the solid-liquid separation of the material, and the upper and lower filter belts are reused after being washed to carry out the concentrated pressure filtration in the next cycle.
Advantages:
1. Automatic control and continuous operation
2. Low energy consumption and long service life
3. High dehydration efficiency and high solids content of mud cake
4. Easy to manage and maintain
5. Low noise, less chemicals
6. Economic and reliable, wide application range
Principle
Owing to the high mobility of liquid sludge, free water, no compressive capacity, so the first entered the gravity dehydration, remove the water of the free, reduce the liquidity of the sludge, and make the floccules and produce larger binding force between particles, and then enter the wedge preloading dehydration stage, the sludge after slight pressure dehydration, liquidity is almost completely lost, to prepare for the cyclotron dehydration and shear dehydration, the gravity sludge dewatering and wedge after dehydration, basic will free water and moisture removal within the floccules, enter the cyclotron dehydration zone, through swing roller diameter changes, gradually increase the mesh belt tension and dehydration gradually formed,When the mud of the mesh belt enters the roller body with small diameter, the squeezing force generated by the stretching force of the filter belt and the dehydration cake are sandwiched between the upper and lower layers of the filter belt, and the shearing force generated by the different rotation direction of the filter belt is used for dehydration treatment.

Features
1. Gravity dehydration zone
After the sewage is pumped into the sludge mixing tank and mixed with the polymer flocculant, the fine suspended matter in the sludge is acted on by the polymer flocculant to form larger colloidal pinnate particles, and then flows into the sludge distributing device of the filter press in the direction of gravity flow, so that the colloidal pinnate sludge is evenly distributed on the filter cloth.
The filter cloth in the gravity dewatering zone moves horizontally, and the capillary water turns into free water through the modulating sludge. Under the action of gravity, the filter cloth is separated from the mud. The function of the gravity dewatering zone is to increase the sludge concentration and stabilize the ruby-feathered sludge, so as to facilitate subsequent pressing and dehydration.
2. Pressure dehydration area
In this area, the upper and lower press cloth gradually converge, sludge is gradually squeezed, sludge concentration continues to increase.
3. Pressurized dehydration area
After entering pressure dehydration, caught in the filter cloth up and down between the squeezing roller interplanting of sludge in the ordering of the S shaped S move up and down, and gradually increase the pressure and shear force of capillary bound water glue pinnate sludge squeezed out, producing a dry sludge cake, by scraping mud unit discharge outside, at this point, to complete the dehydration process.
