Combined high-strength fatigue-resistant metal composite filtering core

Abstract

The invention discloses a combined high-strength fatigue-resistant metal composite filtering core, which comprises a plurality of filtering units connected sequentially, wherein the filtering unit comprises a filtering pipe section, both ends of the filtering pipe section are respectively connected to an outer pipe joint and an inner pipe joint, the inner pipe joint of the filtering unit on the end portion is connected to a plug, the filtering pipe section comprises a support pipe and a metal filtering cylinder sleeved on the support pipe, and the support pipe is provided with a hole. According to the present invention, the combined high-strength fatigue-resistant metal composite filtering core has characteristics of high mechanical strength and low flow resistance; under the instantaneousimpact and frequent back-blowing condition under high back-blowing pressure, the filtering core can ensure the rigidity and the integrity of the metal filtering cylinder so as to enhance the structural strength and the fatigue damage resistance of the filtering core; and the filtering core is easy to assemble so as to effectively reduce the maintenance frequency during the production operation and prolong the service life.

Description

technical field [0001] The invention belongs to the technical field of filter elements, and in particular relates to a combined high-strength, anti-fatigue metal composite filter element. Background technique [0002] The filter element made of metal porous material has ideal and uniform pore size distribution and excellent fluid permeability, high strength, can better withstand thermal stress and impact, and can be machined, welded, cleaned and regenerated, especially suitable for high cleanliness, High-safety purification systems are increasingly used in high-temperature, high-pressure filtration and separation processes. When the internal pores of the filter element are blocked by particles or a thick filter cake layer is formed on the surface, it is necessary to use a higher pressure gas to generate a strong impact force through instantaneous release, reversely blow through the filter element pores, and restore the filter ability of the filter element. [0003] Due to t...
