Description

Filter assembly and candle filter Technical Field The utility model relates to the technical field of filtering equipment, in particular to a filtering component and a candle filter. Background The candle filter belongs to a kind of widely used in industry fields of petroleum, plastics, electroplating, chemical industry, ceramics, pharmacy and sugar making, etc. the main purpose of the candle filter is to remove solid impurities such as organic melt, carbonized particles and metal oxide in the melt, the candle filter gradually replaces filter pressing type and bag type filtration, becoming the mainstream filtration mode, wherein the multiple repeated use of the filter medium saves a large amount of filtration consumables. Currently, candle filters generally employ a filter assembly as a core unit, the filter assembly primarily comprising a terminal and a plurality of cartridges. The liquid discharge ends of all the filter cores are directly connected in the connecting holes of the terminals, and concentrated discharge of liquid is realized through the terminals. However, in the drainage process, the filtered liquid is directly discharged from the connecting hole and the drainage pipe of the candle filter, and when flowing from the connecting hole to the drainage pipe, the liquid flow path is not guided, so that a local retention phenomenon is easily generated, and the drainage efficiency is affected.
