Abstract
The invention provides a heater and an electrifying dry burning enamel technology for manufacturing the heater. The heater comprises an electric heating element, a flange, temperature measuring tubes, a terminal piece and a magnesium rod. The flange is arranged on one side of the electric heating element. The electric heating element internally comprises a guide rod, an electric heating wire, magnesium powder and a steel belt. The terminal piece is arranged on the flange. An enamel protecting layer is arranged on the surface of the electric heating element. The heater is optimized in the enamel technology, and only the dry burning electrifying technology is needed to be conducted on an enamel layer, so that a layer of enamel glaze slip is dipped on the surface of a tube body of the enamel layer; the enamel glaze slip is sintered on the surface of the tube body through dry burning, so that the enamel glaze slip is completely attached to the tube body and a compact and firm enamel layer is formed, and the effects of resisting corrosion, preventing incrustation, preventing cold area rusting and the like are achieved. According to the heater and the electrifying dry burning enamel technology for manufacturing the heater, the problems of incrustation forming, corrosion and the like of a cold area and the tube body when a heating tube operates in water in long term can be effectively solved, and the service life of products is prolonged.
Description
Technical field
The present invention relates to a kind of daily tubular electrothermal element, particularly relate to a kind of heater of surperficial enamel and manufacture the energising dry combustion method enamel technology of heater.
Background technology
At present, electric heater is fast with its heating, easy for installation, simple advantage is used to be commonly used in life, but the fouling of electric heater, corrosion, the problem ubiquity such as get rusty, electroplating technology traditional at present, the all inevitable scale problems of the anticorrosion material of direct use, although continuous tunnel furnace high-temperature tubring can solve a fouling difficult problem, but it is oxidized without enamel position (heating element heater cold junction part) in process of passing through tunnel high-temperature tubring process, thus very easily there is problem of rustiness in long-term work in water, have a strong impact on service life and the security of product, therefore, solve the fouling occurred in the medium-term and long-term work of heater water, corrosion, the technical barrier such as to get rusty seems particularly important.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of heater and manufacture the energising dry combustion method enamel technology of heater, the technical barrier got rusty by the fouling that uses energising dry combustion method enamel technology can avoid occurring in the medium-term and long-term work of heater water, burn into.
In order to solve the problem; the invention provides a kind of heater and manufacture the energising dry combustion method enamel technology of heater; heater includes electrical heating elements, flange, temperature tube, terminal plate, magnesium rod; the side of described electrical heating elements is provided with flange; the inside of described electrical heating elements includes draws rod, heating wire, magnesium powder and steel band; described flange is provided with terminal plate, and the surface of described electrical heating elements is provided with enamel protective layer.
Further improvement is: described flange is also provided with temperature tube and magnesium rod, described electrical heating elements, employing nickel-based brazing technology mode welding between temperature tube and flange.
Further improvement is: described electrical heating elements is bending structure, includes double-H groove weld 180 ° of bending structures or double-H groove weld 70 ° of bending structures or single U100 ° of forward and reverse bending structure.
Further improvement is: existing by electrical heating elements cleaning, drying and processing, again electrical heating elements is immersed in Enamel Slip, making its surface uniform cover the laggard electric dry combustion method that works of one deck glaze slip makes body produce heat from inside to outside, and surperficial glaze slip is attached on body.
Further improvement is: described electrical heating elements enamel thickness is 0.1mm-0.4mm.
The invention has the beneficial effects as follows: heater of the present invention is optimized in enamel technology, only need to carry out dry combustion method energising technique to enamel layer, its tube surfaces is made to soak one deck Enamel Slip, sintered at tube surfaces by dry combustion method, reach and adhere to body more completely and form a kind of fine and close, firmly enamel layer, reach anticorrosive, the effect such as get rusty in scale-deposit-preventing, anti-cold-zone, the present invention effectively can solve in the long-term water of heating tube the problem such as cold-zone, pipe shaft fouling, corrosion working and occur, improves product service life.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Wherein: 1-electrical heating elements, 2-flange, 3-temperature tube, 4-terminal plate, 5-magnesium rod, 6-draws rod, 7-heating wire, 8-magnesium powder, 9-steel band, 10-enamel protective layer.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and the present embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1; present embodiments provide a kind of heater and manufacture the energising dry combustion method enamel technology of heater; heater includes electrical heating elements 1, flange 2, temperature tube 3, terminal plate 4, magnesium rod 5; the side of described electrical heating elements 1 is provided with flange 2; the inside of described electrical heating elements 1 includes draws rod 6, heating wire 7, magnesium powder 8 and steel band 9; described flange 2 is provided with terminal plate 4, and the surface of described electrical heating elements 1 is provided with enamel protective layer 10.Described flange 2 is also provided with temperature tube 3 and magnesium rod 5, described electrical heating elements 1, employing nickel-based brazing technology mode welding between temperature tube 3 and flange 2.Described electrical heating elements 1 is bending structure, includes double-H groove weld 180 ° of bending structures or double-H groove weld 70 ° of bending structures or single U100 ° of forward and reverse bending structure.
First by electrical heating elements cleaning, drying and processing, then electrical heating elements is immersed in Enamel Slip, make its surface uniform cover the laggard electric dry combustion method that works of one deck glaze slip and make body produce heat from inside to outside, surperficial glaze slip is attached on body.Described electrical heating elements enamel thickness is 0.1mm-0.4mm.
Heater of the present invention is optimized in enamel technology, only need to carry out dry combustion method energising technique to enamel layer, its tube surfaces is made to soak one deck Enamel Slip, sintered at tube surfaces by dry combustion method, reach and adhere to body more completely and form a kind of fine and close, firmly enamel layer, the effect such as reach anticorrosive, get rusty in scale-deposit-preventing, anti-cold-zone, the present invention effectively can solve in the long-term water of heating tube the problem such as cold-zone, pipe shaft fouling, corrosion working and occur, improves product service life.
