Description

Magnetic filtering scale-proof device for boiler

The utility model relates to the device that a kind of convection cell carries out magnetic filtration and magnetic treatment, is particularly useful for the processing to domestic water or boiler feed water.

Water is well-known problem once heating very easily fouling.In order to address this problem, people study and have released the various devices that water is carried out magnetic treatment, to reduce or to prevent the harm of incrustation scale.One class is external magnetic type (being that magnet is outside pipeline), product as used American technology production, though the closed circuit magnetic field intensity of this product is more than 10000 Gausses, but the magnetic of covering owing to iron pipe, internal magnetic field can only reach about 500 Gausses, and the main magnetic line of force is parallel to water (flow) direction, so treatment effect is not good enough.Another kind of is internal magnetization (being that magnet is in pipeline), as Chinese patent CN2033401 disclosed " device for magnetic treatment for fluid " and CN87214253 disclosed " running water magnetizer ".Though this class has overcome the magnetic of covering of iron pipe, improved magnetic field intensity and magnetic treating result (CN2033401 disclosed " device for magnetic treatment for fluid ", because of its main magnetic line of force is not parallel to water (flow) direction, treatment effect is still not good enough), but it is the same with external magnetic type, all reckon without water except that Han Tan Suan Calcium and magnesium carbonate, also be mingled with some sand, soil, ferromagnetic material and other impurity, and in processing procedure, one, can cause magnet short-cut path and reduce magnetic field intensity and magnetic treating result because of ferromagnetic material deposition gradually on magnet; Two, sand, soil and other impurity one side and the ferromagnetic material effect that deposits, blocking pipe reduces flow, because of removing, has reduced the quality that makes water on the other hand.

Task of the present utility model provides a kind of magnetic the filtration and the strong magnetic filtration of the incorporate boiler simple in structure, that magnetic field intensity is high, convenience, long service life are cleaned in dismounting of magnetic treatment process scale prevention device.

In order to finish above-mentioned task, a magnetic filter is housed propping up the magnetizer front end that is configured to by pipeline, magnet, non-magnetic conduction.Magnetic filter mainly is made of magnetic screen pipe, deflector apron, filter magnet, screen pack and deposition vessel.The magnetic screen pipe is "T"-shaped, and the vertical tube opening also links to each other with deposition vessel; Filter magnet is installed in magnetic screen pipe vertical tube position; Deflector apron is positioned at the transverse tube at magnetic screen pipe transverse tube and the crossing middle part of vertical tube, will manage anyhow to intersect partly to be divided into paddle hole, and a screen pack is arranged on the apopore.

After water flows into the inlet opening of vertical tube through the water inlet of magnetic screen pipe transverse tube one end, promptly enter in the filter deposition cavity of magnetic screen pipe vertical tube and deposition vessel formation, make ferromagnetic material contained in the water be filtered magnet and hold, most sand, soil and other impurity also are deposited filtration here.From the water that the apopore that screen pack is arranged flows out, enter again in the magnetizer pipeline by the high-strength magnets of non-magnetic conduction support suspension support and be magnetized, flow out from outlet pipe then.

Because the utility model is become one with magnetized water preventing fouling and magnetic filtering technique, the feasible fouling that had both reduced and prevented water, can not cause magnet short-cut path again because of the absorption deposition of ferromagnetic material on the magnetization magnet, reduce magnetic field intensity and magnetic treating result, but also prolonged the service life of magnetizer.Secondly, deposition vessel is detachable or direct with the ball valve deslagging on it, and dismounting is cleaned convenient.Once more, because magnetizer adopts high-strength magnets, whole space field intensity can reach 3000～7000 Gausses, so magnetic treating result is fine.Use the utility model to handle domestic water and boiler feed water, but not only antiscale is energy-conservation, can also improve the quality that makes water.

The utility model also can be used for handling other fluid except that being used for handling the water.
