Abstract
The invention discloses a self anti-scale corrosion-resisting electrical heated tube, relates to the technical field of electrical heated tubes, in particular to a self anti-scale corrosion-resisting electrical heated tube. The electrical heated tube is characterized by consisting of an external metal pipe casing and an internal metal pipe casing which are made of two different types of metallic materials, wherein an air layer is arranged between the external metal pipe casing and the internal metal pipe casing; and the middle section of the electrical heated tube is provided with a casing merge point pressed by the external metal pipe casing and the internal metal pipe casing. The electrical heated tube has the advantages of effectively solving the scaling problem on the surface of the electrical heated tube so that the electrical heated tube can keep normal heat conduction, improving the corrosion resistance of the electrical heated tube, prolonging the service life of the electrical heated tube, and greatly improving the safety performance and service cycle of the whole machine.
Description
Affiliated technical field
The present invention relates to the electric heating tube technical field, relate in particular to a kind of self anti-scale corrosion-resisting electrical heated tube.
Background technology
The structure and the manufacturing of existing water heating electrothermal tube all are by eduction rod, heating wire, and magnesia powder, processing such as metal outer pipe combine.The electrothermal tube that this traditional structure and production technology produce is in adding the process of hot water, because calcium ion in the water and carbonic acid ion are easily attached to the electric heating tube surface, form lime scale, the regional water quality basicity that has is very high, heating time one is long, the electrothermal tube surface can form serious incrustation scale, thereby the heat that causes electrothermal tube is difficult to conduction to come out, cause the heat efficiency to reduce greatly on the one hand, conducting heat on the other hand causes the electrothermal tube internal temperature to raise slowly, makes heating end the fusing of the heating wire in the electrothermal tube, or causes the electrothermal tube internal temperature to raise slowly owing to conduct heat, make insulation descend the magnesia powder sintering, directly influence the security performance of complete machine.For removing incrustation scale, the technology of removing the electrothermal tube incrustation scale with timer control with hot water or cold water's exchange is arranged again, but complex structure, many accessories have not only been increased, also influenced firing rate, therefore how effectively to solve electric heating tube incrusted problem in water heating process just becomes the target that whole electrothermal tube manufacturing is pursued always.
Summary of the invention
Defective at above-mentioned technology, in order to overcome the deficiency that this traditional handicraft is brought, the present invention is through research and development and a large amount of tests, a kind of new technical scheme is proposed, can effectively solve electric heating tube surface scale problem, thereby make electrothermal tube keep normal heat conduction and improve electrothermal tube resistance to corrosion, prolong operating period of electrothermal tube, can improve security performance and the life cycle of using complete machine of the present invention greatly.
The present invention is achieved by the following technical solutions: the present invention includes outer metal pipe box, interior metal pipe box, high temperature oxidation resisting magnesium powder, feature of the present invention is: outer metal pipe box and interior metal pipe box that electrothermal tube is made by two kinds of different metal materials are formed, establish an air layer between outer metal pipe box and the interior metal pipe box, at the interlude of electrothermal tube the merging point of metal pipe box and the compacting of interior metal tube cover outside is arranged, the two ends of electrothermal tube respectively have a high-frequency welding name a person for a particular job outside the metal pipe box be connected with interior metal tube cover, be built-in with resistant to elevated temperatures magnesia powder at interior metal pipe box, the eduction rod one end coiling heating wire at electrothermal tube two ends.Because the difference of outer metal pipe box and two kinds of different metal material thermal coefficient of expansions of interior metal pipe box, add that the warm-up movement of air in heating process in the two metal tube inner room air layers forms little vibration of electrothermal tube, thereby resisted the formation of electrothermal tube surface incrustation scale.
Effective result of the present invention is: the electric heating tube of electric heating tube that this technology produces and traditional handicraft manufacturing has been done a large amount of contrast verifications, also there is the high area of imitation water quality basicity to make and heats two weeks in the more a high proportion of buck continuously, no matter the result is under normal conditions or in buck, this electric heating tube all will be far superior to look into the electric heating tube that technology is made from the ability of anti-incrustation scale, add the compound resistance to corrosion that has also improved electric heating tube greatly that utilizes metal outer pipe in two, can effectively solve electric heating tube surface scale problem, thereby make electrothermal tube keep normal heat conduction and improve the resistance to corrosion of electrothermal tube, prolong the operating period of electrothermal tube, can improve security performance and the life cycle of using complete machine of the present invention greatly.
Description of drawings:
Accompanying drawing 1 is the generalized section of patent structure of the present invention.
Wherein (1) is eduction rod, and (2) are heating wire, and (3) are outer metal pipe box, and (4) are high temperature oxidation resisting magnesium powder, and (5) are the ratio-frequency welding contact, and (6) are interior metal pipe box, and (7) merge point for pipe box, and (8) are air layer, and (9) are electrothermal tube.
Embodiment:
Below specify a kind of embodiment of patent of the present invention with reference to the accompanying drawings.
As shown in Figure 1, the present invention includes for eduction rod be eduction rod (1), be heating wire (2), outer metal pipe box (3), interior metal pipe box (6), high temperature oxidation resisting magnesium powder (4), outer metal pipe box (2) and interior metal pipe box (6) that electrothermal tube of the present invention (9) is made by two kinds of different metal materials are formed, establish an air layer (8) between outer metal pipe box (3) and the interior metal pipe box (6), have at the interlude of electrothermal tube (9) that the sleeve pipe (6) of metal pipe box (3) and the compacting of interior metal tube cover merges point (7) outside one, respectively there is a ratio-frequency welding contact (5) that outer metal pipe box (3) is connected with interior metal pipe box (6) at the two ends of electrothermal tube (9), be built-in with resistant to elevated temperatures magnesia powder (4) at interior metal pipe box (6), eduction rod (1) the one end coiling heating wire (2) at electrothermal tube (9) two ends.
Heating wire (2) is wound on eduction rod (1) two ends; again high temperature oxidation resisting magnesium powder is presented in the interior metal pipe box (6); then with interior metal pipe box (6) die casting to the outer metal pipe box (3); two ends are at argon; carrying out ratio-frequency welding contact (5) (guaranteeing pore-free) under the compound gas shiled of hydrogen connects; by high precision apparatus and detecting instrument the outer metal pipe box (3) of two kinds of different metal materials and the gap of interior metal pipe box (6) are made between 0.02mm-0.03mm, be in of outer metal pipe box (3) and interior metal pipe box (6) the flattening compacting of the mode of punching press at this electrothermal tube (9) interlude then two kinds of materials.Because the outer metal pipe box (3) of two kinds of different metal materials and the difference of interior metal pipe box (6) thermal coefficient of expansion, add little vibration of the warm-up movement formation electrothermal tube (9) of the air in the air layer (8) in heating process between outer metal pipe box (3) and interior metal pipe box (6), thereby resisted the formation of the surperficial incrustation scale of electrothermal tube (9), according to the needs of match appliance complete machine, the present invention can make different geometries.
