Description

Technical Field

[0001] The invention relates to the technical field of halogen heating tubes, in particular to a halogen heating tube with a protective function. Background Art

[0002] Halogen tube is a sealed light-emitting heating tube filled with halogen inert gas, with tungsten filament in the middle, which is divided into white and black (because the cost of white tungsten filament is much higher than that of black tungsten filament, it is not popular in the market). Halogen tube has the advantages of high thermal efficiency, no oxidation during heating, long service life, and some models also have additional functions such as timing, rotation, and humidification. Halogen heating tube uses 3400℃ tungsten filament and high temperature resistant quartz glass tube with halogen mixed gas as protective gas, and is processed into various shapes (ring, pear, U, C, straight tube) of far-infrared halogen heating lamp.

[0003] Halogen heating tubes have the following characteristics: radiation heating, high power, high thermal efficiency, fast heating, no degradation of far-infrared radiation performance after long-term use, working temperature ≤800℃; service life ≥5000 hours, low cost, easy installation, environmental protection, no pollution, etc.

[0004] Advantages of halogen heating tubes: no need for far-infrared coating, good spectral radiation matching absorption characteristics, no degradation of radiation performance after long-term use, and high electrothermal conversion efficiency. It saves about 30% energy compared to general heating elements, has a high working temperature and a wide range of choices. Among them, the ceramic cap encapsulation type has a maximum temperature resistance of 800°C, fast heating, small thermal inertia, high temperature resistance, corrosion resistance, good thermochemical performance stability, long service life, insulation strength, and no pollution. It is a clean heater that meets the requirements of high-paced and high-quality modern production, and is suitable for household appliances with high sanitation requirements. It is very convenient to design, manufacture, and install, and is economical and safe; halogen heating tubes are widely used in various types of heaters, heaters, bathroom heaters, disinfection cabinets, dishwashers, ovens, ovens, food processors (baking), fireplaces, heating lamps, heating treatment, surface heating, vegetable greenhouse insulation planting, automobiles (aircraft), paint booths, pharmaceutical industry, stadiums, open restaurants, workshops, hospitals, railway junction heating, light wave rooms, saunas, drying and drying and paint baking equipment, etc.

[0005] At present, as the heating time increases, the temperature of the porcelain seat will continue to rise with the temperature of the lamp tube, which will lead to a decrease in the service life of the equipment where the lamp tube is installed and the connection structure of the porcelain seat. The temperature of the equipment continues to increase due to long-term light exposure, which accelerates the aging of the equipment and causes many safety accidents. At the same time, since most heating tubes use tungsten filaments to directly connect with the connecting rods, when the tungsten filaments are burned out and damaged, it will affect the entire heating tube, resulting in waste. In addition, many heating tubes have high heat consumption and waste heat energy. Therefore, we have made improvements to this and proposed a halogen heating tube with a protective function. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The present invention provides a halogen heating tube with a protective function, comprising a heating tube body, one side of the heating tube body is fixedly connected to an outer shell, the outer side of the outer shell is fixedly connected to a first heat-insulating collar, a fixing groove is provided inside the outer shell, a connecting head is fixedly connected inside the fixing groove, one end of the connecting head is fixedly connected to a wiring rod, the outer side of the wiring rod is threadedly connected to two wiring nuts, a washer is provided between the two wiring nuts, the washer is sleeved on the outer side of the wiring rod, one end of the heating tube body is fixedly connected to an insulating ceramic head, the outer side of the insulating ceramic head is fixedly connected to a second heat-insulating collar, and one side of the insulating ceramic head is fixedly connected to a wire.

[0008] As a preferred technical solution of the present invention, a tungsten wire is arranged inside the heating tube body, one end of the tungsten wire is fixedly connected to one side of the connecting head, the other end of the tungsten wire is fixedly connected to a stainless steel terminal, and the other end of the stainless steel terminal is fixedly connected to one side of the wire.

[0009] As a preferred technical solution of the present invention, the stainless steel terminal and one end of the wire are arranged inside the insulating ceramic head.

[0010] As a preferred technical solution of the present invention, insulators are arranged at both ends of the interior of the heating tube body, a sealing layer is fixedly connected to one side of the insulator, and a heat insulating gasket is arranged on one side of the sealing layer.

[0011] As a preferred technical solution of the present invention, the thermal insulation gasket is sleeved on the outside of the tungsten wire, and the tungsten wire passes through the sealing layer and the insulator in sequence.

[0012] As a preferred technical solution of the present invention, the interior of the heating tube body is filled with halogen.

[0013] As a preferred technical solution of the present invention, the outer side of the heating tube body is coated with a heat insulating coating.

[0014] The beneficial effects of the present invention are:

[0015] 1. This kind of halogen heating tube with protective function can effectively block the heat caused by the internal tungsten wire from being transferred to the insulating ceramic head through the set insulation gasket. Due to the material characteristics of the ceramic head, even if a small amount of heat is transferred out, it will be dispersed, thereby directly reducing the heat when using the heating tube, greatly improving the service life of the equipment, reducing the aging speed of the equipment, and reducing the occurrence of safety accidents.

[0016] Second, this kind of halogen heating tube with protective function has a connector at one end of the tungsten wire and a stainless steel terminal at the other end. When the connecting rod is connected to an external power supply, the tungsten wire will be heated through the connector, so that the heating tube body will generate heat energy. If the tungsten wire is damaged, the tungsten wire can be directly replaced and the heating tube body can be retained, thereby saving costs. In addition, the outer side of the heating tube body is coated with a heat-insulating coating, so that the heat energy generated by the tungsten wire can be preserved for a longer time, thereby improving the heating effect of the heating tube body and preventing the loss of heat energy.
