Description

Nonmetal water tank boilers heated electrically heater-type leads directly to Optical wave electric heating tube mounting structure

Technical field

This utility model relates to electric boiler, relates generally to the mounting structure of optical wavelength radiation heating electrothermal tube.

Background technology

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

Another number of patent application 201510261254.3 Optical wave electric heating tube has two kinds: one to be semi-conductor electricity heat pipe, is by semiconductor heating material, is coated in glass tubing inner wall surface, forms one layer of conducting film, and has binding post, can produce infra-red radiation and heat energy after energising; Two is luminous energy electrothermal tube, is at the built-in carbon fiber of glass tubing or metal heating wire, produces infra-red radiation and heat energy after energising; Below being all that the water around electrothermal tube is heated, also referred to as heater-type, its mounting means is to be welded with metal water tank by metal canula, it is ensured that tank seal, and by electrothermal tube by installing pad, is placed in sleeve pipe, finds following defect in practice:

1. owing to electrothermal tube is glass, long again, in long-distance transport, there is electrothermal tube glass breakage, the work and heating wire still can be energized, it is possible to make water charged by metal canula; Meanwhile, meeting scaling;

2. pad is installed long-term by, after high heat, producing carbonization, electrothermal tube off-center, produce displacement;

3. two ends seal, and expand, squeezed by installation pad, even draw bad electrothermal tube after inner air heating.

Utility model content

The purpose of this utility model is, for drawbacks described above, electric boiler is improved scheme, optical wave heating method is applied on boilers heated electrically.

Technical measures of the present utility model are:

Water tank 1 adopts plastic material, with blowing or Shooting Technique manufacture, on the straightway of water tank, it is shaped with the joint of threaded (including inside/outside screw thread) or with the joint 2 of flange, by metal or non-metallic casing 3, being contained in the endoporus of concentric joint 2, there is sealing member 4 at two ends, by nut or lid 5 compression, it is ensured that sealing member 4 makes water tank 1 water-tight;Electrothermal tube 6 has mica sheet 7 and non-metal frame 8 by two ends, is arranged in the air in metal canula 3; One layer of intermediate glass pipe is had between electrothermal tube 6 and metal canula 3; Having gap between metal canula 3 and intermediate glass pipe, high-temperature seal adhesive local in two ends is clung, and does not stop the air after being heated between two-layer to flow; The mica sheet 7 at electrothermal tube 6 two ends and non-metal frame 8 is porose or gap, communicates with outside air; With glass tubing alternative metals sleeve pipe 3, then do not need glass bushing, another feature is that electrothermal tube 6 is installed in air 11, when filling water in water tank 1, do not discharge water and can take out or install.

The beneficial effects of the utility model be heating wire be contained in glass tubing and electrothermal tube integral installation in air 11, also have one layer of glass tubing outside electrothermal tube, safety is significantly high; Simultaneously when electrothermal tube damages, also can change when filling water in water tank.

Accompanying drawing explanation

Detailed description of the invention

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

Fig. 1 Fig. 2 is non-metal water tank electric boiler structural representation, described straight-through Optical wave electric heating tube refers to and can be optionally plugged into from two ends, for this threaded joint or flanged (FLGD) joint 2, system is in water tank straightway both sides, must keep concentric, guarantee that metal or non-metallic casing 3 installation site are correct, by nut or lid 5, sealing member 4 is compressed, it is ensured that tank seal; Position and the quantity of joint set on demand.

Described metal canula or glass bushing 3 can be selected, and are all be sleeved on outside electrothermal tube 6, and when adopting metal canula 3, between metal canula 3 and electrothermal tube 6, dress intermediate glass pipe improves safety, does not fill intermediate glass pipe also within this patent is protected; If directly with glass bushing 3, it is desirable to the wall thickness > 2mm of glass bushing 3; When this mounting means electrothermal tube damages, do not discharge water, i.e. replaceable electrothermal tube.

Described mica sheet 7 can play the heat insulation and effect of centering.

Described water tank 1 includes horizontal or vertical, including single barrel or twin-tub.

Owing to electric boiler uses power, from several kilowatts to hundreds of kilowatt, electrothermal tube 6 with some, when controlling temperature, balanced can reduce the electrothermal tube quantity of the work that is energized, it is possible to use three phase mains.
