Bag FilterWhat are the structures of the upper cover?
What are the connection methods and upper cover structure of bag filters? According to the filtering conditions and process requirements, the following characteristics of single bag filters with inlet and outlet and top cover forms need to be selected:
■ Head type (welded); Large processing capacity, small volume, simple structure, and large pollutant holding capacity; Low pressure loss, low operating costs, and significant energy-saving effects.
Flat cover type (welded); The upper cover structure is flat and equipped with M14/M16/M20 locking ring bolts. It has many advantages such as simple and reasonable structure, good sealing performance, strong circulation capacity, and easy operation.
■ Concave cover type (casting); Produced using precision castings, it has high manufacturing accuracy, few welds, stable pressure resistance, and is easy to operate and disassemble quickly and conveniently.
■ Turtle back type (casting); The top in and bottom out filtration method allows the liquid to flow from a higher position to a lower position The filter bag is not affected by turbulence, improving the filtration efficiency and service life of the filter bag.
■ Sanitary grade top in bag filter; Welding type top in structure, precision polished inner and outer surfaces, up to 1200 mesh, low outlet filtration method allows the liquid to flow from high to low, and the parts in contact with the liquid meet food grade hygiene requirements.
Polypropylene injection molding type; 100% all plastic polypropylene material can meet the filtration applications of many chemical acid and alkali liquids. The injection molded casing is seamless and has precise specifications; A high-quality, high-efficiency, economical and practical product that is resistant to high pressure, high temperature, acid and alkali.
