Abstract

The utility model relates to a filtering apparatus for drinking water, which is composed of a top cover, a casing body which has the cylindrical upper part and the conical lower part and a filtering element. The utility model uses diatomite as a filtering agent which is applied on the filtering element to form a filter membrane, so as to remove suspended substances, colloid and microparticles in the water. After the water is filtered, the water turbidity can achieve zero degree, and therefore, the utility model can achieve very high transparency. The utility model has the advantages of simple equipment, convenient operation, installation and maintenance, and low cost of preparing the water.

Description

A kind of filtering apparatus for drinking water

A kind of filtering apparatus for drinking water relates to the water treatment device manufacturing technology.

Because pollution of waterhead, the waterworks conventional water treatment process is difficult to remove the middle dissolubility pollutant that anhydrates, organism particularly, brought harm to HUMAN HEALTH, so deep purification for tap water just has been subjected to extensive attention, multiple deep purifying water has been arranged in the market, as: pure water, ultrapure water, space water, distilled water or the like.Produce pure water, ultrapure water, one of major equipment of space water are a kind of very meticulous membrane filtration-reverse osmosis.Often HUMAN HEALTH useful mineral substance and trace element have also been removed, this type of water of people's long-term drinking is equally to healthy unfavorable except removing objectionable impurities in the water for it, and produce pure water, ultrapure water, the equipment of space water etc. and technology are complicated, and water producing cost is higher.

At the deficiency of producing deep purifying water at present, through studying for a long period of time, the utility model provides a kind of can effectively remove material harmful in the water in to the deep purification for tap water process, can keep main equipment-kieselguhr filter again to the advanced water purifying technology of human body beneficial's mineral substance and trace elements, and purification process equipment is simple, water producing cost is low, the filtering apparatus for drinking water that not only can use separately but also can connect with other purifiers and use.

The utility model is made of housing and filter element, adopt diatomite as flocculating aids, in advance it is coated on the filter element in the filtration unit during work and forms filter membrane, hang thing and colloid in order to remove floating in the water during filtered water, filter back water turbidity reaches the 0--0.1 degree, the transparency height of water, the removal of bacteria rate is also high.Filtration unit can rinse out the filter membrane that lost efficacy with the function of device itself easily after working after a while, recoats one deck diatomite filter membrane then on filter element, to guarantee the drainage quality.

The advantage of this device is: simple in equipment, and volume is little, convenient operation and management, wherein the structure of filter element not only makes things convenient for precoating but also be easy to back flushing, makes that this device also can be according to raw water quality and filter back water quality requirement, precoating or replacing flocculating aids kind, specification and quantity, easy to use flexible.

Accompanying drawing is the utility model embodiment, wherein:

Fig. 1 the utility model structural representation;

Fig. 2 filter element structural representation;

Now in conjunction with the accompanying drawings the utility model is further described.

The utility model is by top cover 1, and top is cylindrical, and the bottom is conical housing 2 and is installed in its inner filter element 3 formations.Top cover 1 is connected with housing 2 usefulness flanges.Porose dividing plate 4 is arranged between top cover 1 and the housing 2, and filter element 3 is fixedly mounted on the porose dividing plate 4.Filter element is by annular top board 5, post 6, and woven wire 7, base plate 8, steel loop 9 firmly is formed by connecting, and filter element center pillar 6 is the sexangle setting, coated outside woven wire 7.Post 6 is earlier by steel loop 9 tensioning from inside to outside, thereby woven wire 7 also is tensioned and is sexangle, the distortion of woven wire 7 under filter pressure is restricted, and then post 6 is fixedlyed connected with base plate 8 with top board 5 respectively.Device is elder generation's precoating diatomite slurries on the woven wire 7 of filter element 3 in the running, as filter membrane, begin water filtration subsequently, behind drainage after a while, the filter membrane on the counterflush filter element 3 rinses out filter membrane, and filter element also rinsed well, and then begin new precoating-filtration.

Claims

A kind of filtering apparatus for drinking water comprises top cover (1), housing (2), and filter element (3), porose dividing plate (4) is characterized in that: filter element (3) is by top board (5), post (6), woven wire (7), base plate (8), steel loop (9) firmly connects and composes.
