DNT-3000 Spiral Screw Press Sludge Dewatering Equipment 80m³/H With 3000mm Belt Width

A certain amount of filtrate is produced during the operation of a sludge dewatering machine, so a supporting filtrate recovery system is required. The filtrate can be reflowed to the front end of sewage treatment for reprocessing, improving the utilization rate of water resources, reducing sewage discharge volume, meeting environmental protection requirements, and lowering the sewage treatment costs of enterprises.

This equipment consists of belt concentrator and dewaterer. The sludge is mixed and reacted sufficiently in the sludge mixer after the flocculant is added. Afterwards, the sludge flows into the gravity dewatering section. A lot of free water in the sludge flows out of the gap of filter belt under the action of gravity and the free water enters into the water collection tank. Afterwards, it is guided by wedge precompression section so that the sludge is leveled gradually and it is dewatered further after slight squeezing. Then, the sludge enters into S-shape multi-roll squeezing section and it is clamped in the middle between upper layer of filter cloth and lower layer of filter cloth. The sludge is squeezed repeatedly by several rolls in different diameters. As this time, the sludge is sheared to facilitate the sludge to dewater further to form the cake. Finally, the scraper is used to scrape down the cake and transport out the cake. The upper and lower filter belt can be reused after washing.

• Stepless regulating motor drive can regulate the running speed at any time and it has strong adaptability
• The specially-made flushing nozzle and clogging-prevention device will flush off the filter belt
• The T-shape water leakage groove is used in the dewatering head roll to squeeze off the water to flow out quickly
• The gravity dewatering section is of inclined design. The static head of sludge is enlarged to enhance the dewatering effect so that the sludge can be thickened sufficiently before squeezing
• Compact structure of whole machine, automatic deviation rectification of filter belt, low operation noise, power consumption saving, less chemicals consumption, good dewatering effect and low operation expense
