Problems solved by technology

The existing filter assembly has large volume, low pressure resistance and high maintenance cost. The filter element cannot be cleaned online. After the filter screen is blocked, it must be removed from the filter for cleaning. The cleaning time is long, which affects the service life of the filter screen and is not conducive to continuous production.
In addition, because the replacement of filter elements will waste time and materials, the frequency of filter element replacement will be minimized during the production process, and some partially clogged filter elements will continue to be used. These partially clogged filter elements will cause large fluctuations in filtration effect and pressure

Abstract

The invention discloses a filter element for filtering high-viscosity fluid, comprising a supporting body with a filtration pore and a filter screen which is arranged at outer side of the supporting body and covers the filtration pore, the inner side of the supporting body is communicated with a filter element discharging port, the outer side of the supporting body is that one side of the supporting body is communicated with the filter element charging port, and the inner side of the filter element discharge port is that one side of the supporting body is communicated with the filter element discharging port; the filter element in the invention has high-pressure resistance, is hard to damage and has long service life; the filter element can be applied to the filter which carries out back flushing, when the filter element is plugged, on-line back flushing can be realized, continuous on-line work of the filter can be realized and the maintaining cost is low.

Description

technical field [0001] The invention relates to a filter element for filtering high-viscosity fluid, in particular to a backwashable filter element for filtering high-viscosity fluid. Background technique [0002] Filtrating the solution or melt to remove impurities in the solution or melt during polymer processing is one of the factors related to the processing performance and quality of the product, and in some cases the impact of the filtration process on processing performance and quality is crucial. In most cases the filtration process needs to be carried out continuously, keeping the pressure fluctuations small. The existing filter assembly has large volume, low pressure resistance and high maintenance cost. The filter element cannot be cleaned online. After the filter screen is blocked, it must be removed from the filter for cleaning. The cleaning time is long, which affects the service life of the filter screen and is not conducive to continuous production. . In a...
