Durable filter element of water purification equipment and preparation method of durable filter element

Abstract

The invention belongs to the field of preparation of non-woven materials, and relates to a durable filter element of water purification equipment, a preparation method of the durable filter element and the water purification equipment comprising the durable filter element. According to the durable filter element, solid powder modified particles are adopted to modify a spun-bonded fiber web twice; first solid powder modified particles applied in the first modification are mainly distributed on the surface of the spun-bonded fiber web; and second solid powder modified particles applied in the second modification are mainly distributed in the middle of the spun-bonded fiber web, and through two times of modification treatment, the modification treatment of the whole spun-bonded fiber web is complete and sufficient; maximum performance of modification treatment is played; and by means of a fluidized bed spraying device with relatively high and uniform solid powder spraying capacity, the adhesion firmness of solid powder modified particles and fibers is improved, the solid powder modified particles are not prone to falling off, secondary pollution to a water source is avoided, the solid powder modified particles can play a role for a long time, and the frequency of replacing the filter element is effectively reduced.

Description

technical field [0001] The invention belongs to the field of nonwoven material preparation, and in particular relates to a durable filter element of water purification equipment and a preparation method thereof. Background technique [0002] As people's hygiene requirements for drinking water are getting higher and higher, water purifiers are used more and more widely in various occasions (such as homes, businesses, and some entertainment venues, etc.), and traditional reverse osmosis water purifiers need pre-assembly Install the filter element and the reverse osmosis filter element, the filter element assembly is generally a filter bottle with a filter element, or a filter bottle with multiple pre-filter elements. [0003] Chinese patent CN201911224557 discloses a large flux four-in-one filter element structure, including a filter bottle, a filter bottle cap, a water guide cylinder, a PP composite filter element, a reverse osmosis filter element, a PP upper end cap, and a P...

Problems solved by technology

In actual use, the main purification and interception functions are the second-stage filter element and the third-stage filter element, and the replacement cycle of the second-stage filter element and the third-stage filter element is short and expensive, and the second-stage and third-stage filter elements are frequently replaced. It will lead to high cost of water purification equipment, which will make water purification equipment unacceptable by consumers
