Description

Novel filter core and filter comprising same

Technical Field

The utility model belongs to the technical field of filter core and filter, concretely relates to novel filter core and contain filter of this filter core.

Background

The filtration is an important method in liquid-solid separation, and filters capable of automatically backwashing are mostly adopted for large-flow and large-batch liquid filtration. At present, filters for automatic back washing mainly comprise medium filters, screen filters, filter cloth filters, fiber filters, membrane filters and the like. Each filter has its applicability. The filter cloth filter is widely applied to the field of solid-liquid separation as a main cleanable filter, and is wide in filtering precision and various in filter cloth types. Common filter cloth filters in the market comprise a multi-disc filter, a rotary drum filter and the like, the filter is generally regenerated by high-pressure water washing, but in order to meet the cleaning requirement, the whole filter does not have pressure to operate, the filter cloth filling area in the system is small, the system occupies a large area, and the backwashing water consumption is also large. Collection of the filter cake is also difficult. The American Aquatech company develops a filter cloth filter disc filter, adopts a vacuum sucking mode for backwashing, greatly improves the filling area of filter cloth, but the pressure of vacuum sucking does not exceed 1 atmosphere, and is difficult to realize effective backwashing on certain sticky impurities. In addition, the filter is only suitable for water body filtration and can not collect filter cakes. In China, filter cloth is covered on a porous lining to form a candle type filter, but the back washing effect is very poor, and filter cakes cannot be well collected. Based on the present situation, the utility model discloses the people think develop a loading area big to the filter cloth filter that can high-efficient back flush and effectively collect the filter cake will have very big market prospect.
