1, introduction
Belt filter dewatering machine is provided in accordance with the layout of the roller is divided into horizontal layout (PSN), vertical layout (PLN) series two kinds, can continuous production, low energy consumption, mud cake moisture content is low, large capacity, high degree of automation, stable performance, low maintenance rate, easy operation, easy maintenance, easy maintenance, is the ideal equipment of sludge dewatering treatment;
2, Function
Mainly used in sewage treatment process sewage, textile printing and dyeing, electroplating, paper, leather, brewing, food processing, coal, petrochemical, chemical, metallurgy, pharmaceuticals, ceramics and other industries in the sludge dewatering process is a plate and frame pressure filter dryer replacement products;
3, working principle
Belt filter press dewatering work process can be divided into the sludge dewatering machine flocculation, gravity dehydration, transition dehydration, filter press dewatering four basic processes.
Flocculation sludge: sludge before dewatering process must go through flocculation, flocculation refers flocculant (polyacrylamide ammonium common solvent) of sludge pretreatment, flocculants and sludge into the line mixer at the same time, were uniformly mixed and adequate response, flocculant sludge solid phase particle adhesion occurs, resulting in agglomeration, the solid phase and liquid phase separation to enter the gravitational dewatering section.
Gravity dewatering process: After the flocculation of sludge, is distributed to the filter press filter belt, randomly run, in the case without external force, gravity and the remaining free water prolapse, so that the sludge in the dewatering zone before entering the transition aqueous lower rates. Gravity sludge dewatering segment dwell time of 20 seconds or more, ensure that free water as much as possible prolapse.
Transition dewatering process: gravity sludge dewatering, with the movement of the belts into the wedge-shaped area between the upper and lower filter belt, in the role of upper and lower filter belt slowly, so that the sludge is also free water clearance gradually being squeezed out of the sludge can smoothly into the filter press dewatering zone. This area is a key part of the decision dehydration capacity size.
Filter press dewatering process: filter press dewatering zone is progressively decreasing diameter of the pressure roller of the composition, pressure roller arrangement conducive to the smooth water flowing out of the filter press sludge in the filter press dewatering zone repeatedly been progressively increasing squeeze effects of pressure and shear forces, making sludge free water clearance water are squeezed out as much as possible.
YIMEI belt type filter press is a new-style high-efficiency sludge treatment equipment developed by our company based on the digestion and absorption advanced foreign technology , which has the advantages of high efficiency, low energy consumption, better dehydration effect, simple structure, easy maintenance, low noise, steady operation, safe and reliable, continuous automatic production etc. now have widely used in solid-liquid separation,such as the project of petroleum, chemical, coal, metallurgy, building materials, light textile, food and water supply and drain environmental protection etc.
Sludge belt filter press increased concentration based on original belt filter press , sludge inspissation machines including condensed section, dehydration section, sludge mixed reaction system, which can put the second pond sludge (water ratio 99.2-99.6%) concentrated dehydration directly, thus eliminating the traditional enrichment pool, saving a lot of investment.
Belt filter is an efficiency equipment by further dehydrating process of concentrated (water ratio 95-98%) material into filter cake dehydration ,with the feature of continuous automatic production, low production cost and installation, can change different mesh filters, continuous stepless speed regulation, adapting to different kinds of material solid-liquid separation. Whole equipment structure is reasonable, prevent water splashed outside, high inatalltion accuracy of roller serial, few times adjust deviation, extended the life of filters, bearings, and pneumatic component, main transmission adopts motor stepless speed regulation, increases the speed range, operation stable, the front of rinse water add cleaning brush, improved filters washing effect, reduce wash water yield,increase the rate of sludge dewatering.
