Abstract
The utility model relates to a high-power radiant tube. Because heating wires are heated in a straight state and have too small exposed areas, common heating radiant tubes are poor in radiating effect, poor in strength of tube core structure and short in service life. The high-power radiant tube comprises a tube core, a heating band, a flange, connecting screw bolts, a circular insulating brick and extraction electrodes. Through holes are arranged inside the tube core and the circular insulating brick, and the flange, the circular insulating brick and the tube core are sequentially connected through the connecting screw bolts and are fixed by nuts. The tube core is composed of a tube core upper portion and a tube core lower portion, the tube core lower portion is formed by a plurality of tube core units, the outer walls of the tube core units are equipped with helical grooves, the heating band is arranged in the helical grooves and is in laminated spring shape, two sides of the tube core are respectively equipped with the extraction electrodes, and one end of each extraction electrode is equipped with a groove to be connected with the heating band to form a conducting loop. The utility model is simple, convenient and reliable, saves one-third cost, is low in error rate, high in power, fine in radiating effect, high in heat efficiency and long in service life, saves energy and reduces cost.

Technical background
Electric heating is one of principal mode of industry heating, and along with the startup of national energy-saving and emission-reduction with to the attention of efforts at environmental protection, electric heating more and more is subject to people's attention.The needs of electric heating equipment are also more and more, and it is also very big as the effect of the main element of electric heating equipment to add heat radiation tube.The heat radiation tube that adds commonly used mainly is made up of steel protective casing, heater strip, tube core and extraction electrode.This heating tube heats at linear state owing to heater strip, the heater strip negligible amounts of layout, and the power of distribution is less; Tube core is made cylindric by refractory material, the many apertures of tube core intermediate distribution, heater strip are fixed in the aperture of refractory material; Heater strip forms the loop by the welding at two ends, is given staying forming two heating electrodes two first days of a year or a month by top, and heating electrode and external power source form the loop.The problem that exists: 1. single radiant tube heating power is less, can not produce big power in limited heating region; 2. the welding point of heater strip is more, because inconvenience is keeped in repair in integral installation in the steel protection tube; 3. the heater strip radiating effect is poor, and the heat efficiency is lower; 4. because the heating tube temperature is higher, and the steel protective casing is made of special steel material, cost is than higher; 5. the tube core internal holes is too many, and the heater strip exposed area is too little, and radiating effect is poor, the tube core structure intensity difference, and useful life is short; 6. long-term use cost height.
The utility model content
The purpose of this utility model is to provide that a kind of volume is little, power big, good heat dissipation effect, high-power radiant tube that cost is low.
For achieving the above object the technical scheme that the utility model is taked:
Its special character of the utility model is: described a kind of high-power radiant tube comprises tube core, extraction electrode, heating tape, flange, connecting screw rod, circular insulating brick; Described tube core, circular insulating brick inside are provided with through hole, and flange, circular insulating brick, tube core connect by connecting screw rod successively, and fix with nut; Described tube core is made up of tube core top, tube core bottom; Described tube core bottom is made up of the tube core unit, and its outer wall is provided with helicla flute, and the heating tape is arranged on stacked spring shape in the helicla flute; The tube core both sides are provided with extraction electrode respectively, and extraction electrode one end is provided with groove, are connected with the heating tape, form the galvanic circle, and the other end of extraction electrode is connected with external power source with binding clip respectively.
Above-mentioned high-power radiant tube is fixed by flange and heating furnace body.
Above-mentioned tube core element number is 2-5.
It is 3-5 that above-mentioned tube core, circular insulating brick 3 inside are provided with number of openings.
Above-mentioned tube core adopts carborundum and clay material.
The beneficial effects of the utility model:
1, with the heating tape upright around, form the shape of folded spring, integral body is embedded in the external spiral groove of tube core, and is fixing simple and convenient reliable;
2, the protective casing of heat resisting steel making accounts for 1/3rd of integral radiation pipe cost, and the utility model need not heat-resisting steel protective casing and means cost-saved 1/3rd;
3, the heating tape is whole coiling, no too much pad, and it is low to connect reliable failure rate;
4, the big good heat dissipation effect of power, heat efficiency height;
5, energy savings reduces cost;
6, long service life, long-term use cost is little.
