As shown in Figure 5, current enter in filter core inner cylinder through capping inner ring water inlet 3, and water is from the inside of filter core to exosmosis, and water, filtering through filter core 2, is removed the harmful substance in water, arrives filter core 2 outer surfaces, then by priming device, is drawn down together and is filtered.As the suspended material containing in running water, colloidal substance, dissolved substance (ion and molecule), organic matter and hydrone itself, if cover to filter with filter core of the prior art when by filter, although the suspended material in water, colloidal substance are removed, but soaking through long, adhesive glue more or less can decompose and bring in water, the adhesive glue that is particularly positioned at the outer region of filter core more easily enters water body, to water pollution.And used capping of the present utility model, these problems all can solve, and simple in installation and unloading process, this capping is beneficial to volume production, reuses.
According to test, 1 gram of active carbon has 500-1000m
2surface area, filtering is granular with active carbon, particle diameter is generally 1-4mm, these micropores can play suction-operated, and activated carbon dechlorination is not exclusively that it also has catalytic action due to physisorption, make chlorine residue further change into carbon compound, its reaction mechanism is
C
12+H
2O====HC1+HOCl
HOCl====HCl+[O] active carbon
C+[O]====CO
C+2[O]====CO2
Therefore, there is not absorption saturation problem in active carbon, just lose a small amount of charcoal in whole absorption dechlorination process.So activated carbon dechlorination can move considerable time.Dechlorination active carbon filter can also be removed the colloid in water, although naked eyes cannot be seen the colloid thing in water breakthrough, the in the situation that of ionization, water is assembled in a large number by the salt adhering to, and becomes the suspension that can with the naked eye see.After dechlorination, water flows into accurate active carbon filter, and more tiny organic substance in accurate charcoal absorption water is eliminated peculiar smell, again removes and remains in the colloidal substance in water; From foregoing description, can find out, running water can not directly be drunk, this just requires, and any one accessory all needs to reach its required requirement, if filter core does not go wrong, and water after filtration still measures water quality not up to standard in detecting, this will be processed from the connection aspect of capping, and capping of the prior art sticks with glue mode, and glue can contact with water, small part can be water-soluble, makes water quality not up to standard.Use on the other hand glue connected mode, can leave gap, and in prior art, be plane body during misoperation, water is easy to from gap, to flow out.Therefore, utilize water-purifying filter filter core of the present utility model capping can solve problem in this respect completely.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
