Description

Melt-blown filter core convenient to maintain Technical Field The utility model belongs to the technical field of melt-blown filter elements, and particularly relates to a melt-blown filter element convenient to maintain. Background The melt-blown filter element takes nontoxic and odorless polypropylene particles as raw materials, and is manufactured into a tubular filter element through the processes of heating and melting, spinning, traction, receiving forming and the like. If the raw material is mainly polypropylene, it can be called a PP melt-blown filter element. The filter element not only can be applied in the field of water purification in a large batch, but also has excellent chemical compatibility, and is suitable for filtering strong acid, strong alkali and organic solvents. The sewage-receiving capacity is strong, the service life is long, and the cost is low. When the melt-blown filter element is used, a filter element cover is usually arranged outside the melt-blown filter element, a top cover is arranged on the top side of the filter element cover, and a water inlet pipe and a water outlet pipe are arranged on the top cover. The sewage is conveyed into the filter element cover through the water inlet pipe, filtered by the melt-blown filter element and discharged through the water outlet pipe, so that the sewage is filtered. However, in actual use, the melt blown filter element gradually decreases in filtration after 3-6 months of continuous use. In this case, to ensure stable operation of the filter system, replacement of the melt-blown filter cartridge is recommended. However, the problem is that the filter element cover and the top cover are connected by adopting a plurality of groups of bolts and nuts. The connecting mode can play a role in fixing, but when the melt-blown filter element is maintained and replaced, the disassembly and assembly process is very complicated and time-consuming, the complicated and time-consuming processes are caused by disassembling and assembling multiple groups of bolts and nuts, the melt-blown filter element can be taken out from the filter element cover only by disassembling and assembling the bolts and the nuts in sequence, and the maintenance difficulty and the time cost are improved.
