Abstract
The utility model discloses a compound filter cartridge with a ceramic membrane. The compound filter cartridge comprises a shell and a central tube, wherein the inside of the shell is divided into an upper space and a lower space; the central tube penetrates through the upper space and the lower space of the shell and is fixed in the center; a water pressure regulating valve of the central tube is arranged in a partition part between the upper space and the lower space; the ceramic membrane is arranged on the inner surface of the central tube in the upper space; a filtration layer is arranged on the outer surface of the central tube in the lower space. The compound filter cartridge with the ceramic membrane is reasonable in structure and good in filtration effect; with the adoption of the ceramic membrane, the purposes of separating, concentrating, purifying and removing impurities and bacteria are achieved; by virtue of the compound filter cartridge, the molecular-scale filtration is achieved, and the quality of drinking water is improved.
Description
Technical field
The utility model relates to water purification field, particularly a kind of ceramic membrane composite filter element.
Background technology
Water resource is the most critical resource of human being's production life, and nowadays, ecological environment is seriously damaged, and water pollution is serious, and the improvement that the protection of water resource and water pollute becomes the problem that modern society pays close attention to most.China is a country that drought and water shortage is serious.Freshwater resources total amount is 28000 billion cubic meters, accounts for 6% of global water resources, is only second to Brazil, Russia and Canadian, occupy the 4th, the world, but only have per capita 2200 cubic metres, be only world average level 1/4, the U.S. 1/5, be the whole world one of 13 countries that water resource is the poorest per capita.According to detection, national most urban groundwaters are subject to point-like and facial contamination to a certain extent at present, and have the trend increasing the weight of year by year.The water being on the rise pollutes the use function that has not only reduced water body, further aggravate the contradiction of shortage of water resources, the strategy of sustainable development that China is being implemented has been brought and has been had a strong impact on, but also serious threat is to city dweller's safe drinking water and the people's health.
Along with the raising of people's living standard, the quality requirement of resident living water is more and more higher, drinking mineral water has the shortcoming that cost is high, and nearest mineral water manufacturer produce mineral water also there are quality problems, make resident to mineral water hope but halt.And running water generally all needs just to use as drinking water through filtering, at present, the filtration of running water mainly realizes by filtering hydrophone, and to be that people are healthy play certain positive role with water filter.But the problems such as unreasonable structure, filter course are few, poor filtration effect, follow-up maintenance trouble that the filter core in existing water filter exists.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the purpose of this utility model is to provide rational in infrastructure, a kind of ceramic membrane composite filter element of good filtration effect.
The utility model solves the technical scheme that its technical problem adopts: a kind of ceramic membrane composite filter element, comprise shell, central tube, wherein: in described shell, be divided into He Xia space, space, described central tube runs through the space up and down of shell and is fixed on center, described central tube is provided with hydraulic-pressure regulating valve at upper and lower spatial separation place, described central tube is provided with ceramic membrane at the inner surface in upper space, and described central tube is provided with filter course at the outer surface in lower space.
As further improvement of the utility model: described ceramic membrane is divided into carrier layer, intermediate layer and separating layer.
As further improvement of the utility model: described filter course is provided with fibrage and active carbon layer.
As further improvement of the utility model: described shell water inlet and delivery port and hydraulic-pressure regulating valve are provided with potted component.
As further improvement of the utility model: described central tube is loose structure, and surfaces externally and internally is equipped with rough texture.
Compared with prior art, the beneficial effects of the utility model are: the utility model integrates external-compression type and inner pressed filter core, be provided with active carbon layer absorb absorption fine particle after by fabric filtration, regulate hydraulic pressure through hydraulic-pressure regulating valve, filtered by ceramic membrane, thereby the object that reaches separation, concentrated, purifying, impurity elimination, degerming, realizes molecular level and filters, and improves the quality of drinking-water.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Existing accompanying drawings and embodiment further illustrate the utility model:
With reference to figure 1, a kind of ceramic membrane composite filter element, comprise shell 1, central tube 2, wherein: in described shell 1, be divided into 101He Xia space, space 102, described central tube 2 runs through the space up and down 102 of shell and is fixed on center, described central tube 2 is provided with hydraulic-pressure regulating valve 3 in 102 separated places, upper and lower space, and described 102Nei water source, lower space is filtered into external-compression type and filters, and described 101Nei water source, upper space is filtered into inner pressed and filters.
Described central tube 2 is provided with ceramic membrane 4 at the inner surface in upper space 101, and described ceramic membrane 4 is divided into carrier layer, intermediate layer and separating layer.Described carrier layer contacts with central tube 2 outer surfaces.Described carrier layer increases the mechanical strength of ceramic membrane 4, aperture is 1-20 μ m, voidage is 30%-65%, the aperture of the aperture ratio carrier layer in described intermediate layer is little, prevent in separating layer preparation process that particle is to the infiltration of carrier layer, thickness is 20-60 μ m, porosity is 30%-40%, described separating layer has separation function, aperture is 0.8 μ m-1 μ m, and thickness is 3-10 μ m, and porosity is 40%-50%, the pore-size distribution of described ceramic membrane 4 is reduced to separating layer gradually by carrier layer, forms asymmetric structure distribution.Water source under external force, small-molecule substance permeation ceramic membrane 4, macromolecular substances is held back by ceramic membrane 4, thereby reaches the object of separation, concentrated, purifying, impurity elimination and degerming.
Described central tube 2 is provided with filter course 5 at the outer surface in lower space 102.Described filter course is provided with fibrage and active carbon layer.Described fibrage and central tube 2 outer surfaces are affixed, and described active carbon layer is wrapped in fibrage, and water under pressure ecto-entad enters central tube 2, active carbon layer absorb absorption fine particle after by fabric filtration.
The water inlet 6 of described shell 1 and delivery port 7 and hydraulic-pressure regulating valve 3 are provided with potted component.The water inlet 6 of described shell 1 is located at lower space 102, and described delivery port 7 is located at space 101.
Described central tube 2 is loose structure, and surfaces externally and internally is equipped with rough texture.
In sum; those of ordinary skill in the art reads after the utility model file; make other various corresponding conversion scheme according to the technical solution of the utility model and technical conceive without creative mental labour, all belong to the scope that the utility model is protected.
