Abstract

A high-temperature melt pipe comprises a to-be-heated steel pipe. The existing high-temperature melt pipe is improved, and the existing resistance wire is replaced by an electromagnetic induction wire which is wound on the to-be-heated steel pipe. The high-temperature melt pipe overcomes shortages that the existing high-temperature melt pipe utilizes the resistance wire to heat with heating temperature achieving about 300 DEG C, but the resistance wire is easy to be burnt out because of high temperature aging and then is relatively high in maintenance load and thermal loss. The high-temperature melt pipe utilizes the electromagnetic induction wire to replace the existing resistance wire, is high-efficient and energy-saving, has high thermal efficiency achieving 95%, and saves electricity by 60% compared with a resistance wire heating form under the same conditions. Moreover, preheating time of the high-temperature melt pipe is reduced by a half, thereby reducing production operation cost. A heating portion utilizing the induction wire can not generate more heat, and then the high-temperature melt pipe is long in service life and simultaneously avoids maintaining frequently and replacing heating rings periodically when utilizing the resistance wire to heat.

Description

The high-temperature fusant pipeline

Technical field

The utility model relates to a kind of high-temperature fusant pipeline.

Background technique

Existing high-temperature fusant pipeline adopts the resistance wire heating, heating-up temperature up to 300 ℃ about, resistance wire blows because of high temperature ageing easily, and about general conventional half a year, the workload of maintenance is relatively large, thermal loss is big, since the resistance wire coiling, the inside and outside two sides heating of circle, and the transmission of heat of its inner face (being close to steel pipe part to be heated) is to steel pipe to be heated, and the outer heat major part of face is lost in the air, causes the loss and waste of electric energy.The rising of ambient temperature, because heat scatters and disappears in a large number, ambient temperature is very big to the production environment influence in rising, especially summer, is the key location of whole production technology and operation as card room, so technological requirement constant temperature and humidity, enterprise has to take air-conditioning to reduce temperature, and this causes the secondary waste of the energy again, therefore strengthens greatly to have added enterprise's invisible waste, also strengthened the cost of production of enterprise, so enterprise urgently wishes to have a kind of appearance of new mode of heating.

The model utility content

At the deficiency that above-mentioned similar technology exists, it is even that the purpose of this utility model provides a kind of heating, the high-temperature fusant pipeline of efficient height, long service life.

The technical solution of the utility model is: comprise steel pipe to be heated, it is characterized in that: existing high-temperature fusant pipeline is improved, adopt the electromagnetic induction line to replace existing resistance wire, on steel pipe to be heated.

In order to play temperature adjustment, energy-conservation effect better, preferred version of the present utility model is: the electromagnetic induction line evenly on steel pipe to be heated, is connected the electromagnetic induction line again with electromagnetism heating control system, power supply.

Can wrap up a layer thickness on steel pipe to be heated is the thermal-protective material of 3-5cm, has following effect, 1. insulation: the scattering and disappearing of temperature of reducing the high-temperature fusant pipeline; 2. heat insulation: the electromagnetism heater wire is carried out heat insulation because heating back metal pipe-wall temperature is very high, generally at 300-500 ℃.

The preferred alumina silicate heat-preservation cotton of described thermal-protective material.

The utility model has the advantages that: the utility model is replaced existing resistance wire by the electricity consumption magnetic induction line, 1. energy-efficient, the thermal efficiency economizes on electricity more than 60% than resistive conductor mode of heating under the equal conditions up to more than 95% on the high-temperature fusant pipeline, and preheat time is more over half than original shortening; 2. reliable many closed loops intelligent control and perfect protective system guarantee system's long-term safety reliable operation; 3. reduce production run cost, heating part and adopt the line of induction self can not produce too many heat, long service life has also avoided the resistance wire heating to need often to safeguard and the periodic replacement heating collar simultaneously; 4. intelligent multi-region thermostatically control electromagnetism heating control system adopts real time temperature and temperature-control range freely to set, and the built-in intelligence chip is regulated output power automatically, regulates automatically according to time and PRODUCTION STATUS, thereby satisfies manufacturing technique requirent.Reduce enterprise's production run cost greatly, reduce the ambient temperature of manufacturing shop, operating environment is significantly improved, also save simultaneously the cost of environment temperature reduction, also improved the thermal effect of high-temperature fusant pipeline, can reach more than 95%, thereby also just enhanced productivity accordingly.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Now in conjunction with the accompanying drawings, technology contents of the present utility model is described further.

Among Fig. 1, comprise steel pipe 5 to be heated, parcel one deck 4cm thick alumina silicate heat-preservation cotton thermal-protective material 4 on steel pipe 5 to be heated at first, again with electromagnetic induction line 3 evenly on steel pipe 5 to be heated, at last electromagnetic induction line 3 is connected with electromagnetism heating control system 1, temperature point for measuring temperature 2, power supply 6.

Working principle of the present utility model:

The utility model utilizes electromagnetic induction principle, electric energy is converted into the device of heat energy, use electromagnetism heating control system 1 free setting temperature point for measuring temperature 2 simultaneously, with 220V, the AC rectification of 50HZ becomes direct current, again direct current is converted to the high frequency current that frequency is 20-40KHZ, can produce the alternating magnetic field that changes at a high speed when the high frequency current that changes flows through electromagnetic induction line 3 at a high speed, when the magnetic line of force in magnetic field during by steel pipe 5 to be heated, can in steel pipe 5 to be heated, produce a large amount of eddy current, steel pipe 5 to be heated itself is generated heat at a high speed voluntarily, and thermal efficiency is far above general heating products.
