Abstract
The invention discloses an infrared ray lamp tube, relating to the technical field of industrial heating, drying or heating devices. The infrared ray lamp tube comprises a transparent glass tube with two ends closed, the glass tube is filled with the inert gas, and the two ends of the glass tube are respectively provided with ceramic insulation installation holders, and through holes are respectively arranged on each insulation installation holder. A tungsten wire is arranged in the glass tube, and at least two support rings are arranged on the tungsten wire at interval. The two ends of the tungsten wire are respectively connected with molybdenum pieces, the other end of each molybdenum piece is connected with a stainless steel terminal through a molybdenum rod, and the other end of each stainless steel terminal is arranged in the through holes and connected with a connecting lead. At least two sets of radial raised sets are fixed on the inner surface of the glass tube, and each set of radial raised set is arranged at the outside of the corresponding support ring. Through the design of the invention, the tungsten wire can not burn the glass tube due to the fact that the support rings are fixed by the radial raised sets, and the tungsten wire can not droop when the glass tube is placed in vertical.
Description
Technical field
The present invention relates to the technical field of industrial heating, oven dry or heating system.
Background technology
Common infrared lamp comprises transparent, sealed at both ends glass tube, and inert gas is set in the glass tube, and the two ends of glass tube are provided with insulating mounting porcelain seat respectively, on each insulating mounting porcelain seat through hole is set respectively; In the described glass tube tungsten filament is set, connects at least two bracket loops on the tungsten filament at interval; The two ends of described tungsten filament connect molybdenum sheet respectively, and the other end of each molybdenum sheet connects tainless terminal by molybdenum rod respectively, and the other end of each tainless terminal is separately positioned in the described through hole, and the other end of each tainless terminal connects lead respectively.The infrared lamp of this structure is when vertically placing, and bracket loop can be sagging, thereby tungsten filament rocks in glass tube, can scorch glass tube, influences the useful life of infrared lamp.
Summary of the invention
The objective of the invention is provides a kind of infrared lamp in order to overcome the deficiencies in the prior art, and tungsten filament can not scorch glass tube when it was vertically placed.
The object of the present invention is achieved like this: a kind of infrared lamp, comprise transparent, sealed at both ends glass tube, and inert gas is set in the glass tube, the two ends of glass tube are provided with insulating mounting porcelain seat respectively, on each insulating mounting porcelain seat through hole are set respectively; In the described glass tube tungsten filament is set, connects at least two bracket loops on the tungsten filament at interval; The two ends of described tungsten filament connect molybdenum sheet respectively, the other end of each molybdenum sheet connects tainless terminal by molybdenum rod respectively, the other end of each tainless terminal is separately positioned in the described through hole, the other end of each tainless terminal connects lead respectively, in the fixedly connected at least two group radial protrusion groups of the inner surface of described glass tube, every group of radial protrusion group is arranged on the outside of corresponding bracket loop.
The present invention is by above design, because radial protrusion group fixing to bracket loop, when glass tube was vertically placed, tungsten filament can be not sagging, thereby tungsten filament just can not scorch glass tube.
As improvement of the present invention, described every group of radial protrusion group comprises two radial protrusions, and two radial protrusions are arranged symmetrically on the same cross section of described glass tube.
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 be among Fig. 1 A-A to view.
Fig. 3 is a B portion enlarged drawing among Fig. 1.
As shown in Figure 1, 2, 3, be a kind of infrared lamp, comprise transparent, sealed at both ends glass tube 1, inert gas 9 is set in the glass tube 1, the two ends of glass tube 1 are provided with insulating mounting porcelain seat 4 respectively, on each insulating mounting porcelain seat 4 through hole 10 are set respectively.Tungsten filament 2 is set in the glass tube 1, connects at least two bracket loops 3 on the tungsten filament 2 at interval.In the fixedly connected at least two group radial protrusion groups of the inner surface of glass tube 1, every group of radial protrusion group is arranged on the outside of corresponding bracket loop 3.Every group of radial protrusion group comprises two radial protrusion 1-1, and two radial protrusion 1-1 are arranged symmetrically on the same cross section of glass tube 1.
The two ends of tungsten filament 2 respectively with molybdenum sheet 5 spot welding, the other end of each molybdenum sheet 5 respectively with molybdenum rod 6 spot welding, the other end of each molybdenum rod 6 and tainless terminal 7 spot welding, the other end of each tainless terminal 7 is separately positioned in the through hole 10, the other end of each tainless terminal 7 respectively with lead 8 punching presses.
Claims (2)
