Description

Backwash filtering electronic water treatment facilities

Technical field

The utility model relates to a kind of electronic descaling device, especially a kind of damp-proof backwash filtering electronic water treatment facilities.

Background technology

Existing electronic descaling device only has the descaling and antiscaling function, does not possess impurity and the function of getting rid of dirt in the filtered water, and the dirt impurity in the pipeline current can not be got rid of all the time, and the result must influence water quality requirement; In addition, when this device was installed in chilled water system, the temperature difference of current and pipeline outer air was bigger in the pipeline, produced the dewfall phenomenon, the water dewdrop that occurs must make electronic devices and components make moist to get wet or short circuit, directly influence the work-ing life and the maintenance cost of this equipment.

Summary of the invention

The purpose of this utility model is to provide a kind of damp-proof backwash filtering electronic water treatment facilities, reduces maintenance cost and increases the service life by moisture preventive measure.

The technical scheme that its technical problem that solves the utility model adopts is: backwash filtering electronic water treatment facilities of the present utility model comprises housing, anode, producer, cartridge filter, water-in, water outlet, recoil mouth, sewage draining exit, thermal insulation layer, it is characterized in that, one end of housing is a water-in, the other end is a water outlet, and the central lines of water-in and water outlet; The leading portion of this housing is provided with the recoil mouth, and back segment is provided with sewage draining exit, and sewage draining exit passes housing and links to each other with cartridge filter through blow-off pipe; The front end of cartridge filter is fixed on the water-in of housing, after bring out the back segment that blow-off pipe is fixed on housing; Producer is fixed on the housing, is separated by thermal insulation layer between producer and the housing, and the output line of producer passes housing and links to each other with anode, and the anodic two ends are separately fixed on the support.

The housing of backwash filtering electronic water treatment facilities of the present utility model is for being provided with the metal cylinder of water-in, water outlet, recoil mouth and sewage draining exit simultaneously, cartridge filter is the metal cylinder that is covered with countless holes or eyelet, and thermal insulation layer is mountain paracril or terpolymer EP rubber.

Backwash filtering electronic water treatment facilities of the present utility model can be used for descaling and antiscaling and the contaminant filter and the sewage backwash of various duct type water systems, this water treatment facilities is simple in structure, compact, installing space is little, relates to the synthesis device of the scale removal of pipeline water system, antiscale, sterilization algae removal, impurity screening, eliminating dirt.

In order more to be expressly understood the present invention, below with specific embodiment and the present invention is described in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of the utility model backwash filtering electronic water treatment facilities.

Description of reference numerals:

1 water inlet, 2 water outlets

Embodiment

As shown in Figure 1, backwash filtering electronic water treatment facilities of the present utility model comprises housing 5, anode 6, cartridge filter 7, blow-off pipe 8, producer 9, output line 10 and thermal insulation layer 11; Its middle shell 5 is as negative electrode, it has water-in 1, water outlet 2, recoil mouth 3 and sewage draining exit 4, the central lines of water-in 1 and water outlet 2, recoil mouth 3 is arranged on the leading portion top of housing 5, sewage draining exit 4 is arranged on the back segment bottom of housing 5, and this sewage draining exit 4 links to each other with cartridge filter 7 through blow-off pipe 8, and the front end of cartridge filter 7 is fixed on water-in 1 place of housing 5, and the rear end of cartridge filter 7 is fixed on the back segment of housing 5 by blow-off pipe 8; Producer 9 is fixed on the housing 5, and is separated by thermal insulation layer 11 between producer 9 and housing 5, and the output line 10 of producer 9 passes housing 5 and links to each other with anode 6, and the two ends of anode 6 are separately fixed on the support 12.

The principle of design of backwash filtering electronic water treatment facilities of the present utility model comprises: the working process of electrostatic-scaling antiscale is: the energy that producer 9 produces is passed to anode 6 through output line 10, make and produce electrostatic field between housing 5 (negative electrode) and the anode 6, when water flows out water-in 1, when arriving water outlet 2 through filter cylinder 7, be subjected to the field energy effect of electrostatic field, after the water dipole is subjected to field action, be forced to arrange continuously by positive and negative ordered orientation ground, the water molecules moment of dipole increases rapidly, water mineral zwitterion (Ca ²⁺, Mg ²⁺, CO ₃ ²⁺, SO ₄ ^2-) will be surrounded by the water dipole, also be forced to by positive and negative orientations in water dipole subgroup, be difficult to be combined into CaCO ₃Deng composition of scale, thereby prevent the generation of incrustation scale.Because of the polarity effect of water, when the water molecules moment of dipole increases rapidly, the mineral ion hydratability is increased rapidly, the incrustation scale of having tied is come off gradually, reach the scale removal purpose; The working process of filtering the recoil blowdown is: when current enter water-in 1, when reaching water outlet 2 through cartridge filter 7, impurity in the water and dirt all are filtered tube 7 interceptions, this process is water filtration, when the normal blowdown of needs, open sewage draining exit 4, can realize the dirt eliminating; When needs recoil blowdown, when thoroughly eliminating impurity and washing and filtering tube, successively close water outlet 2 and water-in 1, open simultaneously recoil mouth 3 and sewage draining exit 4 rapidly, after sewage draining exit 4 was opened, all current were forced to flow to outside the housing 5 via blow-off pipe 8, this moment, cartridge filter 7 interior hydraulic pressure were reduced to negative pressure rapidly, all current oppositely pour cartridge filter 7 immediately, can wash adherent impurity and dirt on it fully, and discharge via blow-off pipe 8 with current; The altitude temperature difference effect that moisture-proof function is based on the dewfall phenomenon of producer 9 is a starting point, cut off the thermal source transmission by thermal insulation layer 11 between producer 9 and the shell 5, prevent the generation of dewfall phenomenon, producer 9 is under the drying regime all the time, can guarantee effectively that the long service life of this device, maintenance cost are low.

As known from the above, backwash filtering electronic water treatment facilities of the present utility model has the function of the pipeline current being filtered scale removal, electronic descaling and electronic devices and components protection against the tide, and the compact construction performance is stable.
