Description

The straight-through Optical wave electric heating tube mounting structure of metal water tank boilers heated electrically heater-type

Technical field

The present invention relates to electric boiler, relates generally to the mounting structure that optical wavelength radiation heats electrothermal tube.

Background technology

Electric boiler is electric water heater, heating power from several kilowatts to hundreds of kilowatt, substantially with electric heater The method of heating water is similar to；The patent of invention number of Chinese Guangdong Shuande Guang Sheng electrical equipment limited company 200810091347.6 it is electric heating tube side heat type heating with patent application 2009101315082.X.

Another 201510261254.3 Optical wave electric heating tube of number of patent application has two kinds：One is semi-conductor electricity heat pipe 6-1, is by semiconductor heating material, is coated in glass tubing inner wall surface, form one layer of conducting film, and have wiring Terminal, can produce infra-red radiation and heat energy after energization；Two is luminous energy electrothermal tube 6-2, is carbon built-in in glass tubing Fiber or metal heating wire, produce infra-red radiation and heat energy after energization；Below all it is that the water around electrothermal tube is entered Row heating, also referred to as heater-type, its mounting means are to weld metal canula with metal water tank, it is ensured that water tank Sealing, and electrothermal tube is padded by installing, it is placed in sleeve pipe, in practice, finds following defect：

1. as electrothermal tube is glass, and long, in long-distance transport, there is electrothermal tube glass and broke Damage, and heating wire still can be powered work, it is possible to make water powered by metal canula；Meanwhile, can scaling；

2. pad is installed for a long time by carbonization after hyperpyrexia, is produced, electrothermal tube off-center produces displacement；

3. two ends sealing, expands after inner air heating, will install pad and squeezes, or even draws bad electrothermal tube.

Content of the invention

The purpose of the present invention is to be improved scheme for drawbacks described above to electric boiler, by optical wave heating method application To on boilers heated electrically.

The present invention technical measures be：

First, there is hole 15 on 1 top semicircular end-face of water tank, have blind flange 16 thereon, on blind flange 16 The out-of-date pouring-in utensil 17 for heating water of current is installed；The out-of-date pouring-in utensil for heating water of the current 17, it is a 18 built-in electrothermal tube 6-1 of hermetic container for having intake-outlet, when discharging water, electrothermal tube 6-1 is connected, Water is heated, is disconnected when closing water.

2nd, on the straightway of 1 casing of metal water tank, welding is threaded connecing for (including inside/outside screw thread) Head or the joint 2 with flange, metal or non-metallic casing 3 are mounted in the endoporus of concentric joint 2, There is sealing member 4 at two ends, are compressed with nut or lid 5, it is ensured that sealing member 4 makes water tank 1 water-tight；Electrothermal tube 6 There are mica sheet 7 and non-metal frame 8 by two ends, in the air in metal canula 3；Electrothermal tube 6 There is one layer of intermediate glass pipe 9 and metal canula 3 between；There is gap between metal canula 3 and intermediate glass pipe 9, Two ends high-temperature seal adhesive local is clung, and does not prevent the air flow after being heated between two-layer；6 two ends of electrothermal tube Mica sheet 7 and non-metal frame 8 have hole or gap, communicate with outside air；With glass tubing alternative metals set Pipe 3, then be not required to glass bushing 9, and another is characterized in that electrothermal tube 6 is installed in air 11, in water tank 1 When filling water, do not discharge water and can take out or install.

The invention has the beneficial effects as follows heating wire be mounted in glass tubing and electrothermal tube integral installation in air 11, electricity There is one layer of glass tubing outside heat pipe, safety is very high；Simultaneously when electrothermal tube is damaged, when filling water in water tank Can change.

Description of the drawings

Fig. 1 Fig. 2 is equipped with the electric boiler inner water tank structural representation of electrothermal tube；

Fig. 3 Fig. 4 is Fig. 1 Fig. 2 erection joint Local maps；

Specific embodiment

In accompanying drawing, water tank 1, have screw thread or flanged joint 2, metal or non-metallic casing 3, sealing member 4, Nut or lid 5, electrothermal tube 6 (semi-conductor electricity heat pipe 6-1, luminous energy electrothermal tube 6-2, metal electric heating pipe 6-3), Mica sheet 7, non-metal frame 8, intermediate glass pipe 9, air 11, hole 15, blind flange 16, current are out-of-date Heat the pouring-in utensil 17 of water, have the hermetically sealed container 18 of intake-outlet.

In Fig. 1 Fig. 2, the straight-through Optical wave electric heating tube is referred to and can be optionally plugged into from two ends, is that this threaded connects Head or flanged (FLGD) joint 2, are welded on water tank straightway both sides, it is necessary to keep with one heart, it is ensured that metal or non-gold Category sleeve pipe 3 installation site is correct, compresses sealing member 4 by nut or lid 5, as long as tank seal just can be with； The position of joint and quantity are set on demand.

The metal canula or glass bushing 3 can be selected, and be sleeved on outside electrothermal tube 6, when using gold During category sleeve pipe 3, between metal canula 3 and electrothermal tube 6, dress intermediate glass pipe 9 improves safety, does not fill Intermediate glass pipe 9 is also within this patent protection；If directly using glass bushing 3, it is desirable to the wall of glass bushing 3 Thick ＞ 2mm；When this mounting means electrothermal tube is damaged, do not discharge water, you can change electrothermal tube.

The mica sheet 7 can play the heat-insulated and effect of centering.

The water tank 1 include horizontal or vertical, including single barrel or twin-tub.

As electric boiler uses power, from several kilowatts to hundreds of kilowatt, electrothermal tube 6 can control temperature with some When spending, can the balanced electrothermal tube quantity for reducing energization work, it is possible to use three phase mains.
