Description

Use the electrothermal water heater of non-metal shell electrothermal tube

Technical field

The present invention relates to water source or connected space heater without water source, having related generally to use the electrothermal water heater of non-metal shell electrothermal tube.

Background technology

The electrothermal tube being currently used in electrothermal water heater, 100% is the tubular electrothermal element produced by technical standard JB/T4088-1999 " daily tubular electrothermal element " or JB/T2379-1993 " tubular metal electric heating element ", be " with metal tube as shell, heating alloy make heater; at one end or two ends have eduction rod; load closely knit magnesium oxide powder dielectric in metal tube, with the element of fixing heater；" it is the existing heating commonly used；This metal shell heating, is completely sunk in the water, after long-time use, meeting scaling, reduces heating efficiency, and corrosion punctures, and makes water charged, is world-famous puzzle.

Summary of the invention

It is an object of the invention to improve for drawbacks described above.

The technical measures of the present invention are that water tank uses metal or nonmetallic materials to make, water tank can be connected with water source or not be connected with water source, when connecting without water source, the water within water tank is artificially to install inlet water tank additional, the electrothermal tube used be have the electrothermal tube of heating wire or non-metal shell in non-metal shell in have two kinds of structures of electrothermal tube:

One is built with heating wire 3 or magnesium oxide powder or air 4 at straight-through non-metallic pipe 7, installs eduction rod 1 at the two ends of heating wire, by nonmetal plug 6, outside protruded tube, has the electrothermal tube 11 of heating wire in becoming non-metal shell；Or at one end close and become blind hole non-metallic pipe 8 built with heating wire 3 and magnesium oxide powder or air 4, eduction rod 1 is installed at the two ends of heating wire 3, and heating wire 3 is bent to U-shaped, make two eduction rods 1 at one end, outside by nonmetal plug 6 protruded tube, in becoming non-metal shell, there is the electrothermal tube 11 (Fig. 5 to Fig. 8) of heating wire；Dry combustion method in described heating wire air in non-metallic pipe.

Two is to have electrothermal tube in non-metal shell: at metal tube 5 built with heating wire 3, with magnesium oxide powder 4, metal tube 5 and heating wire 3 are carried out isolated insulation, installs eduction rod 1 at the two ends of heating wire, by nonmetal plug 6 protruded tube outside, become heater 9；Then heater 9 is contained in non-metallic pipe 7, becomes non-metal shell electrothermal tube 11 (Fig. 1)；Or at metal tube 5 built with heating wire 3, with magnesium oxide powder 4, metal tube 5 and heating wire 3 are carried out isolated insulation, eduction rod 1 is installed at the two ends of heating wire 3, bend to U-shaped after sealing, make two eduction rods at one end, become heater 9, then heater 9 is contained in one end closing and becomes in blind hole non-metallic pipe 8, between the heating wire of bending, have magnesium oxide powder or air 4 or insulant 10；In unlimited one end, non-metallic pipe 8 and heater 9 are fixed, become non-metal shell electrothermal tube 11 (Fig. 2)；Or in straight-through non-metallic pipe 7 or in blind hole non-metallic pipe 8, load electrothermal tube, and by the eduction rod 1 in blind hole one end, bending is turned back to the other end, makes eduction rod in same one end；Described non-metal electric heating pipe is carbon fiber pipe or halide torch, or other can the electrothermal tube (Fig. 3 Fig. 4) of dry combustion method.

Described non-metallic pipe 7 or 8, first-selected quartz glass tube.

The invention has the beneficial effects as follows employing non-metal electric heating pipe, be immersed in water not scaling, heating corrodes never and punctures, and will not leak electricity.

Accompanying drawing explanation

Fig. 1 is that two ends have eduction rod, outside metal tube 5, also has the electrothermal tube of straight-through non-metallic pipe 7；

Fig. 2 is that one end has eduction rod, outside metal tube 5, and the also electrothermal tube of blind hole non-metallic pipe 8；

Fig. 3 is blind hole non-metallic pipe built with electrothermal tube, Fig. 4 is the straight-through non-metallic pipe structure chart built with electrothermal tube；

Fig. 5 is the straight-through built-in heating wire of non-metallic pipe, and Fig. 6 to Fig. 8 is the structure chart of the built-in heating wire of blind hole non-metallic pipe；

Detailed description of the invention

In accompanying drawing, eduction rod or title terminal 1, sealing ring or high-temp glue 2, heating wire 3, magnesia powder or non-metallic insulation thing or air 4, metal tube 5, nonmetal plug 6, straight-through non-metallic pipe 7, blind hole non-metallic pipe 8, heater or electrothermal tube 9, water 10, non-metal shell electrothermal tube 11, metal or nonmetal water tank 15, shell 16, blind flange 17, mounting seat 18, friction top 19.

Fig. 1 to Fig. 8 is the employing non-metal shell electrothermal tube that one end filled in electrothermal water heater or two ends have eduction rod, and there is nonmetal plug 6 termination, and eduction rod 1 is by outside plug 6 protruded tube；Fig. 5 to Fig. 8 is straight-through or has heating wire 3 in blind hole non-metal shell, also magnesia powder or non-metallic insulation thing or air 4, due to heating wire 3 can dry combustion method in atmosphere, therefore can be directly installed in non-metal shell.

Fig. 1 to Fig. 4 is straight-through or in blind hole non-metallic pipe, loads non-metal electric heating pipe, and described non-metal electric heating pipe refers to carbon fiber pipe or halide torch, or non-metal shell electrothermal tube.

Fig. 9 is electrothermal water heater structural representation, and water tank 15, built with electrothermal tube 11, is water outside it, and the shell of this electrothermal tube is made up of nonmetal, and there is heating wire inside, isolates with water glass, never scaling, never punctures.
