Abstract
Description
Technical Field
[0001] The utility model relates to a chemical production filtering system, in particular to a novel disassembly-free filtering system. Background Art
[0002] Traditional chemical filtration systems have a series of defects in production efficiency, maintenance costs and safety. They are usually restricted by the selection of filter media and structural design, which leads to relatively low efficiency. At the same time, regular replacement and cleaning of filter coal increases maintenance costs and may cause production stagnation. In addition, traditional systems are difficult to adapt to the filtering needs of high-temperature or corrosive materials, which limits their scope of application.
[0003] Plate and frame filter press is a common solid-liquid separation equipment in traditional chemical production, which has some obvious defects. First, the operation of plate and frame filter press requires relatively high energy input, resulting in high energy consumption, which increases production costs. Secondly, because it is easily eroded and worn by materials during the filtration process, plate and frame filter presses require frequent maintenance and replacement of parts, which significantly increases maintenance costs. In addition, the operation of the equipment is relatively complicated and requires professional knowledge, which may lead to operating errors. Its applicability to some special materials is limited, especially for sticky materials or small particles. Utility Model Content
