Abstract

The invention discloses a plate-and-frame pressure filtering device for sludge dewatering and drying, and relates to the technical field of sludge treatment equipment. The plate-and-frame pressure filtering device specifically comprises a machine frame, a top frame movably mounted above the machine frame, filter cloth fixedly connected to the bottom of the machine frame, a pressing device fixedlymounted on the outer side of the machine frame, a filter plate movably mounted on the inner side of the machine frame, and material stripping devices movably mounted on the upper surface of the machine frame, wherein the machine frame comprises a base. Through cooperative arrangement of the material stripping devices, servo motors and buffer springs, the servo motors work, turntables can be turned, connecting bulges periodically lift the top frame along limiting rings, the buffer springs reduce the vibrating pressure, a mud cake adhered to the outer surface of the filter cloth is shaken off, the material stripping effect is improved in cooperation with water washing operation, the problems that partial blockage of the filter cloth due to incomplete flushing causes unqualified moisture content of the mud cake and affects sludge treatment are avoided, at the same time, the water source consumption is lowered and the sludge treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a plate and frame filter press device for sludge dehydration and drying. Background technique [0002] The plate and frame filter press is a kind of intermittent solid-liquid separation equipment. It is composed of filter plates and filter frames to form a filter chamber. Separation of solid and liquid, this equipment is widely used in chemical industry, dyestuff, petroleum, ceramics, pharmaceutical, sugar, starch, paint, metallurgy and sewage treatment, etc. It has the advantages of good separation effect, wide application range, simple operation and low investment. Especially for the separation of viscous and fine materials, it has incomparable advantages. [0003] After the plate and frame filter press dehydrates the sludge into a mud cake, the filter plate and filter frame are washed by water washing. After the sludge solidifies and condenses into a mud ca...
