Description
Technical field
The utility model relates to a kind of water filtering device, relates in particular to a kind of rearmounted sterilizing filter element that is applied in the counter-infiltration system.
Background technology
In order to prevent and to reduce transmission of disease, need be to direct drinking water through water treatment modes such as purification and sterilization, filter is a kind of common water treatment facilities, existing water filter generally comprises tubular hollow housing, the shell nozzle end is combined with end cap, be respectively equipped with water inlet and delivery port on the housing other end and the end cap, be filled with filtering material in the housing, common have sponge, an activated carbon granule etc.
As the patent No. be: (Granted publication number: CN2885836Y), it includes water inlet pipe, filter core and outlet pipe this patent to the Chinese utility model patent of ZL200620078813.3 " simple water purification device ".Filter core is an elongated cylindrical, and its inside is filled with sponge, filter course and active carbon.During use, the water inlet pipe end is inserted in the water, from the suction of water outlet pipe end, water is more suitable for drinking through filtering to become with mouth.Above-mentioned patent structure is simple, purification function is comparatively single, and effects such as absorption impurity bacterium have to be strengthened.It is complicated a little to have occurred some structures in the prior art, and the filter that effect and function are strengthened as patent is: the Chinese utility model patent of ZL93322292.7 " the removable combined filter of filter material " (Granted publication number: CN2177516Y) etc.
Polyiodine resin is that treated synthetic a kind of novel disinfection material is the sterilised medium of a class contact, penetrability after being reacted under certain condition by industrial chemicals and poly-iodine solution.Sterilization mechanism: when the moment that bacterium protein directly contacts with polyiodine resin in water, immediately by attack, modification takes place, solidify, the bacterial enzyme system is destroyed, and causes microbial death such as germ, this product is compared maximum characteristics and is with other bactericide:
The first, have sterilization speed and good bactericidal effect fast, energy is kill bacteria, virus thoroughly, and sterilizing rate is at (filtration time 2～4 seconds) more than 99.99%.
Second, safe in utilization, health, health: the micro-mineralizer (I) that bactericide discharged that uses in drinking water is in the national Specification scope, to the human body beneficial, filter surplus iodine in the water of back and can kill bacterium in the secondary pollution that the membrane filtration equipment produces, can remove the green alga in filter and the scuttlebutt effectively.
Three, have and meet the function that bacterium discharges: polyiodine resin has insoluble and stable in water, if in the water when aseptic, then medium keeps stable state, then discharges sterilization fast as bacterium.
But the technology that polyiodine resin is applied in the filter is also rare at present, is necessary to do in this respect a little researchs and improvement.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of sterilization effect good at the above-mentioned state of the art, and the while is the rearmounted sterilizing filter element of compact conformation again, and this filter core is filled the polyiodine resin layer to improve disinfection effect by inside.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of rearmounted sterilizing filter element, comprise tubular shell and the end cap of being located at the rearward end opening part of housing, housing has delivery port, end cap has water inlet, be provided with active carbon layer in the housing, its spy is that the leading section of described housing is filled with active carbon layer near delivery port, and the space of the close end cap of the rearward end of described housing is filled with stenlizing layer.
As preferably, described stenlizing layer is the polyiodine resin layer.
As improvement, improve the bactericidal purifying effect, be provided with the cotton layer of a PP and first spongy layer between described delivery port and the described active carbon layer successively; Described polyiodine resin layer and between described water inlet be provided with the cotton layer of the 3rd PP, second spongy layer and the cotton layer of the 2nd PP successively; Be provided with the cotton layer of the 4th PP between described active carbon layer and the polyiodine resin layer.
Be convenient to the installation that is provided with of the cotton layer of a PP, described housing inner chamber is provided with a filter near delivery port, and this filter has the ccontaining territory of a depression, and the cotton layer of a described PP then is located in this ccontaining territory.Described inner walls is provided with projection near delivery port, and this projection annular radial is arranged on the inner walls, and described filter has the annular folding edge that is held on the aforementioned projection and moves to the delivery port direction with the restriction filter.
Described polyiodine resin layer accounts for the water stream channel of cavity pocket of outer cover 0.2, and the design price ratio is higher like this.
Described housing inner chamber is provided with in the tubular near water inlet and overlaps, should comprise outer cylinder and inner cylinder concentrically with respect to one another and be located at outer cylinder and the cover plate at inner cylinder two ends by middle cover, have the through hole that communicates with aforementioned inner core on this cover plate, described polyiodine resin layer then is filled in described inner core, such structure is convenient to the installation of polyiodine resin layer, the less again volume that takies the housing inner chamber simultaneously also is unlikely to the polyiodine resin layer and vacillates and influence bactericidal effect.
Be provided with sealing ring between described outer drum outer wall and the described inner walls, thoroughly complete to guarantee water filtration.
Compared with prior art, advantage of the present utility model is: be applied to the counter-infiltration system afterbody, can effectively rush out the bacterium that grows from pressure water storage barrel, guarantee water quality, the structural design compact and reasonable is assembled also very simply, and flow velocity, pressure and service life are all relatively more rational.
