Abstract

The utility model discloses a triad filter, which mainly comprises an end cover 1, a shell body 2, a PP fiber filter core 3, an activated carbon filter core 4 and a hollow ultrafiltration membrane filter core 5, the key points of the structure are that: the PP fiber filter core 3, the activated carbon filter core 4 and the hollow ultrafiltration membrane filter core 5 are all positioned in the shell body 2, and the heads and tails of the activated carbon filter core 4 and the hollow ultrafiltration membrane filter core 5 are connected with each other for being arranged in the PP fiber filter core 3; the water inlet end of the shell body 2 is provided with the end cover 1, the lug boss on the inner side of the end cover 1 is connected with the PP fiber filter core 3 and the activated carbon filter core 4. the filter combines three-level filtration in the cylinder body, which occupies a small area, and the utility model has a compact structure and concise appearance, and can reduce the secondary pollution, the making cost is low, and the changing is easy.

Description

Three-in-one filter

The utility model relates to the purification mechanism of a kind of life, industrial use, especially three-in-one filter.

Though the water purifier of Chu Xianing is a lot of in the market, the filter in the water purifier all is cylindrical shell of a filter core, and these filters not only area occupied are big, and increased unnecessary cost, as increased several pairs of die costs.

The purpose of this utility model provides a kind of three-in-one filter, and three kinds of cartridge combination in a cylindrical shell, had both been reduced area occupied, saves manufacturing cost again.

Concrete scheme of the present utility model is: comprise housing, PP fabric filter element, activated carbon cartridge, hollow filter membrane filter core, it is characterized in that: PP fabric filter element, activated carbon cartridge, hollow filter membrane filter core all are positioned at housing, and activated carbon cartridge and hollow filter membrane filter core is end to end is contained in the PP fabric filter element; Water inlet end at housing is provided with end cap.

Adopt the such scheme three-stage filtration to be incorporated in the cylindrical shell, area occupied is little, compact conformation, and outward appearance is succinct, can reduce secondary pollution, low cost of manufacture, it is convenient to change.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a whole schematic configuration diagram of the present utility model.

Fig. 2 is the front view of end cap 1 among Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 2.

As shown in Figure 1: the utility model mainly is made up of end cap 1, housing 2, PP fabric filter element 3, activated carbon cartridge 4, hollow filter membrane filter core 5, connection cover 6.Structural feature of the present utility model is: PP fabric filter element 3, activated carbon cartridge 4, hollow filter membrane filter core 5 all are positioned at housing 2, and activated carbon cartridge 4 and hollow filter membrane filter core 5 end to end being contained in the PP fabric filter element 3; Water inlet end at housing 2 is provided with end cap 1, and the boss of this end cap 1 inboard connects PP fabric filter element 3 and activated carbon cartridge 4.

Also can see from Fig. 1: the afterbody of activated carbon cartridge 4 joins through end cap 1 inboard boss and PP fabric filter element 3 afterbodys, the stem of activated carbon cartridge 4 is connected with hollow fiber ultrafiltration membrane cartridge 5 afterbodys, and the delivery port of activated carbon cartridge 4 inserts in the afterbody water inlet of hollow fiber ultrafiltration membrane cartridge 5, the delivery port of hollow fiber ultrafiltration membrane cartridge 5 inserts in the apopore of housing 2, and the pin on the head end of PP fabric filter element 3 and the housing 2 water side inwalls joins.

As Fig. 2, shown in Figure 3: there is inlet opening 6 in the outside of end cap 1, has apopore 7 on the inboard boss, and the middle part of end cap 1 is provided with cannelure 8, and inlet opening 6 and apopore 7 are communicated with cannelure 8 by four-way 9.

The utility model is performed such work: source water enters from the water inlet of end cap 1, and the first order of flowing through earlier filtration _ PP fabric filter element 3 is removed the solids of water fast, as materials such as iron rust, silt, algae; Enter second level filtration _ activated carbon cartridge 4 again, can effectively remove the material that causes offensive odour and mouthfeel in the water fast; Enter third level filtration _ hollow fiber ultrafiltration membrane cartridge 5 then, can effectively remove bacterium, colloid, protein in the water; Apopore from housing 2 flows out at last.
