Description

Technical Field

[0001] The utility model relates to the technical field of recycled water sludge treatment, in particular to a sludge belt filter press device for a recycled water plant. Background Art

[0002] A filter press is a machine that applies mechanical force to one side of the filter medium to achieve filtration. It is primarily used for solid-liquid separation of sludge (water). The water-containing sludge is pumped to a sludge mixing tank by a sludge pump, where a coagulant is added for thorough mixing. The sludge then flows into a belt-type sludge press, where it is evenly distributed to the gravity dewatering zone. Under the bidirectional guidance of the sludge rake and the action of gravity, the sludge moves along the dewatering filter belt, rapidly removing free water from the sludge. The long gravity dewatering zone maximizes gravity dewatering. The flipped sludge enters the extra-long wedge-shaped pre-pressing and dewatering zone, which slowly clamps the sludge unloaded from the gravity zone, forming a sandwich-like angle layer. This is then subjected to sequential and slow pre-pressure filtration to minimize the residual free moisture in the mud layer. As the upper and lower filter belts slowly advance, the distance between the two filter belts gradually decreases, and the mud layer in the middle gradually hardens. A large amount of free water is removed by the large-diameter filter rollers of the pre-pressing and dewatering, allowing the mud cake to smoothly enter the extrusion and dewatering zone and enter the "S" press section. In the "S"-shaped press section, the sludge is sandwiched between the upper and lower layers of filter cloth and repeatedly squeezed by several press rollers. As the upper and lower filter belts pass through the wavy path formed by the staggered rollers, the alternating up and down positions of the two filter belts generate shear force on the clamped mud cake, which compresses and filters out most of the remaining water in the sludge, prompting the mud cake to be dehydrated again. Finally, the dry mud cake is scraped off by a scraper and transported to the sludge storage area by a belt conveyor or shaftless screw conveyor.

[0003] The existing sludge filter press has a complex structure, low filtration efficiency, short service life, inconvenient maintenance and unstable operation. Utility Model Content
