Further, in the step (3), preliminary compressing bar-shaped activated carbon carries out constant temperature baking by constant temperature baking box
It is roasting.
Further, in the step (4), the bar-shaped activated carbon after cooling is stripped by hydraulic thrust carbon tool.
A kind of application of the complex sintered active carbon filter core of antibacterial zeolite particles, the active carbon filter core are applied to water purifier.
Compared with prior art, the invention has the advantages that：Resisted by the use of silver zinc complex 4A zeolites are carried as main
Microbial inoculum, belong to silver-colored zinc system composite inorganic antibacterial zeolite particles, there is the spy such as safe, has a broad antifungal spectrum, heat-resist, service life length
Point；4A zeolites with special construction have the empty structure that can firmly load antibacterial metal ions as carrier, because it is internal,
Prepared antiseptic has certain slow-release capability, and stability is higher, is suitably applied in anti-biotic material, moreover, 4A types boil
Stone has higher exchange selectivity to silver ion, and its exchange degree can reach more than 75%, and its excellent structure make its with
When water contacts, there is great specific surface area, destroy bacterium living beings enzyme, can effectively kill multiple-microorganism in water, bacterium
Deng, there is obvious advantage as carrier, and because the superior structural of 4A zeolites causes antiseptic hardly dissolution,
Ag, Zn will not be exceeded in water, are effectively guaranteed water quality safety, and it is exceeded to solve purifier filter core, pressure pot bacterium, water outlet
Water quality is not up to standard, it is impossible to the problem drunk, substantially increases the practicality and security of water purifier；And the antibacterial filter core cost
Relatively low, appearance and size can customize, and not influence the use function and outward appearance of water purifier in itself, suitable for almost all net on the market
Water dispenser model, it is used in original purifier to ensure filter core effluent quality security, has very big market value.
