Embodiment 1

[0051] Such as Figure 1 to Figure 6 A high-efficiency multi-stage water purification filter element shown includes a housing 1, an opening 101 is provided at the lower end of the housing 1, and a threaded pipe portion 102 for connecting pipelines is provided at the upper end, and an inner pipe 2 is provided inside the housing 1 , the upper and lower ends of the inner tube 2 are injection-molded with a baffle 201, the baffle 201 fits the inner wall of the outer shell 1, and forms a seal with the outer shell 1, and the lower baffle 201 is provided with a Connected to the water inlet hole 202 of the inner pipe 2, the outer wall of the baffle plate 201 above is evenly distributed with water outlet holes 203 for upward water outlet, and the outer wall of the inner pipe 2 is evenly distributed with water outlet grooves 204. A PP cotton filter element 3 is sheathed on the outside of the inner tube 2, and activated carbon 4 is filled inside the shell 1 at the top of the upper baffle ...

Embodiment 2

[0068] Substantially the same as Example 1, the only difference is that the preparation method of the activated carbon comprises the following steps, and the parts are parts by weight:

[0069] (1) Wash pomelo peel, dry at 105° C. for 6 hours, pulverize, and pass through a 40-mesh sieve to obtain pomelo peel coarse powder;

[0070] (2) Mix pomelo peel coarse powder and activator at a solid-to-liquid ratio of 1g: 4mL, impregnate at normal pressure for 120 minutes, then immerse in 80MPa for 30 minutes, filter with 200 mesh filter cloth, and the obtained solid is impregnated pomelo peel coarse powder ;

[0071] (3) Put the impregnated pomelo peel coarse powder into a tube furnace, raise the temperature to 450° C. at 10° C. / min under nitrogen protection, and keep the temperature at 450° C. for 80 minutes to obtain a carbonized material;

[0072] (4) Take out the carbonized material, mix it with the acid solution according to the solid-to-liquid ratio of 1g: 4mL, soak it under nor...

Embodiment 3

[0076] Substantially the same as Example 1, the only difference is that the preparation method of the activated carbon 4 comprises the following steps, and the parts are parts by weight:

[0077] (1) Wash pomelo peel, dry at 105° C. for 6 hours, pulverize, and pass through a 40-mesh sieve to obtain pomelo peel coarse powder;

[0078](2) Mix pomelo peel coarse powder and activator at a solid-to-liquid ratio of 1g: 4mL, impregnate at normal pressure for 120 minutes, then immerse in 80MPa for 30 minutes, filter with 200 mesh filter cloth, and the obtained solid is impregnated pomelo peel coarse powder ;

[0079] (3) Put the impregnated pomelo peel coarse powder into a tube furnace, raise the temperature to 450° C. at 10° C. / min under nitrogen protection, and keep the temperature at 450° C. for 80 minutes to obtain a carbonized material;

[0080] (4) Take out the carbonized material, mix it with the acid solution according to the solid-to-liquid ratio of 1g: 4mL, soak it under no...

Abstract

The invention discloses a high-performance multistage water-purifying filter element, comprising a housing. The lower end of the housing is provided with an opening; the upper end of the housing is provided with a threaded pipe portion for pipeline connection; an inner pipe is arranged in the housing; a retainer is formed at each of the upper and lower ends of the inner pipe by injection molding;the retainers are attached to the inner wall of the housing and are hermetically fitted to the housing; the lower retainer is provided with a water inlet communicated with the inner pipe; the outer wall of the upper retainer is evenly provided with water outlets that discharge water upward; the outer wall of the inner pipe is evenly provided with outflow slots; the inner pipe is sleeved with a PP(polypropylene) foam filter element; the housing is filled with activated carbon at the top of the upper retainer; the housing is filled with filter sponge at the bottom of the lower retainer; the opening of the housing is fitted with a bottom shell. The high-performance multistage water-purifying filter element is easy to mount and allows a user to change a filter consumable on his or her own.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a high-efficiency multi-stage water purification filter element. Background technique [0002] The long tap water delivery pipelines in the prior art make the tap water contain a lot of harmful substances, such as soluble heavy metal ions, rust, excessive residual chlorine, and germs and viruses. Nowadays, people's safety awareness is constantly improving, and the requirements for water quality are getting higher and higher, so the use of water purification equipment is also increasing. The price of a higher water purifier is usually more than 2,000 yuan, and the filter element is a consumable, which needs to be replaced frequently, and the cost of use is higher. [0003] Based on the above problems, there is a need for a high-efficiency multi-stage water purification filter element that is easy to install and allows users to replace filter consumables by themselves. ...
