Durable filter element for water purification equipment and preparation method thereof

Abstract

The invention belongs to the field of non-woven material preparation, and relates to a water purification equipment durable filter element and a preparation method thereof, and a water purification equipment including the filter element. The invention adopts solid powder modified particles to modify the spunbonded fiber web twice, The first solid powder modified particles applied in the first modification are mainly distributed on the surface of the spunbonded fiber web, and the second solid powder modified particles applied in the second modification are mainly distributed in the middle of the spunbonded fiber web , after two modification treatments, the modification treatment of the entire spunbond fiber web is complete and sufficient, and the effectiveness of the modification treatment is maximized. With the help of a fluidized bed injection device with a strong and uniform solid powder injection ability , improve the adhesion firmness of solid powder modified particles and fibers, solid powder modified particles are not easy to fall off, will not pollute the water source again, and can work for a long time, effectively reducing the frequency of replacing filter elements.

Description

technical field [0001] The invention belongs to the field of non-woven material preparation, and in particular relates to a durable filter element for 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.), traditional reverse osmosis water purifiers need to be assembled before 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 high-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 PP lower end cap. There are raw water inlet, booster pump wate...

AI Technical Summary

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
