Description

Backwash filter type electric water treatment device

1, technical field

The utility model belongs to water technology, specifically a kind of backwash filter type electric water treatment device.

2, background technology

Problems such as the incrustation scale of industrial and civilian water system, burn into pollution are seriously perplexing the mankind always.Traditional antiscaling method is to add the generation that chemical agent stops incrustation scale in water mostly, though this kind method has certain antiscaling effect, but antiscale is not thorough, can not scale removal, and environment there is pollution, can cause again when adding Phosphorus Scale inhibitors and grow fungus algae in the water, a large amount of fungus algae microorganisms can cause line clogging.The electric water treatment device of prior art can antiscale again can scale removal, it is all multi-functional to have sterilization algae removal, rust cleaning inhibition, sterilizing and purifying water quality etc. again, but electric water treatment device is in operational process, because electrode can adsorb a large amount of metal sundries and will have influence on its result of use, and the electric water treatment device of prior art has drawbacks such as being not easy to cleaning and difficult replacing electrode, and life-time service will have a strong impact on its serviceability or inefficacy.

3, utility model content

In view of the deficiency that above-mentioned prior art exists, the utility model provides a kind of backwash filter type electric water treatment device that cleans and change electrode simple in structure, convenient.

The technical scheme that its technical problem that solves the utility model adopts is: backwash filter type electric water treatment device is by housing, cartridge filter, water-in, valve plate, electrode bar, producer, water outlet and sewage draining exit are formed, housing is pipe-like, its entrance end is connected with water-in by end plate, exit end is by shell flange and water outlet preparation, middle by connecting with holding bolt after the gasket sealing, be connected with cartridge filter with water-in in the housing, the other end at cartridge filter is connected with shrouding with screw, be laid with filter pore on cartridge filter and the shrouding, in cartridge filter, be equiped with valve plate near feed-water end, valve plate is fixed on the valve shaft by fixing slightly, valve shaft passes cartridge filter and is installed on the housing, and handle is housed outside housing, be equiped with electrode bar in the cartridge filter behind valve plate, the two ends of electrode bar are installed in the cartridge filter by removable anchor, and sewage draining exit passes housing and links to each other with cartridge filter through blow-off pipe, and sewage draining exit is located at cartridge filter near the shrouding place; Producer is fixed on the housing, and is communicated with by high frequency cable between producer and electrode bar.

During normal the operation, valve plate is for opening shape, sewage draining exit is closed, and current enter cartridge filter, also filter the back by the water outlet outflow through filter pore from water-in, and the impurity of tackling in cartridge filter should carry out the back flushing processing more for a long time, at this moment, close valve plate and water outlet, open sewage draining exit, current are forced to flow to housing by the filter pore before the valve plate after water-in enters cartridge filter, the current that enter housing are again by the filter pore backwash filter tube behind the valve plate, and are discharged by sewage draining exit.

When changing electrode bar, only need pull down water outlet and shrouding just can conveniently take out electrode bar, the replacing electrode bar is more convenient, makes the utility model work more stable, and result of use is better, and has prolonged work-ing life.

The action principle of backwash filter type electric water treatment device of the present utility model is: after the producer energising, make between electrode bar and the housing by high frequency cable and to form high-frequency electric field, high-frequency electric field is to the water excitation activation treatment by cartridge filter, and the glassware for drinking water after the activation treatment has the function of descaling and antiscaling, sterilization algae removal, rust cleaning inhibition, sterilizing and purifying water quality.

The beneficial effects of the utility model are, being directly installed in the various duct type water systems can descaling and antiscaling, sterilization algae removal, impurity screening, blowdown etc. effectively, have simple in structure, easy for installation, take up an area of little, the convenient characteristics such as electrode bar and result of use are good of cleaning and change.
