Abstract

Adopt electric heating water boiler of non -metal casing electrothermal tube, the shell of used electrothermal tube is non -metallic material, it is in through type or blind hole non -metallic pipe (7) or (8) that its one end or two ends have the electrothermal tube of drawing stick (1), is equipped with the electrothermal tube, the electrothermal tube is carbon fiber tube or halogen tube or non -metal casing electrothermal tube or dry combustion method electrothermal tube, and draw forth stick (1) and stretch to the outside of tubes through nonmetal end cap (6).

Description

Use the electric hot water of non-metal shell electrothermal tube

Technical field

The present invention relates to electric hot water, relate generally in electric hot water, the non-metal shell electrothermal tube being immersed in water used.

Background technology

The electrothermal tube being currently used in electric hot water, 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 existing electric hot water is improved.

The technical measures of the present invention are that the water tank of electric hot water is by metal or nonmetal making, built with non-metal shell electrothermal tube 11: be built with heating wire 3 at metal tube 5, with magnesium oxide powder 4, metal tube 5 and heating wire 3 are carried out isolated insulation, the two ends of heating wire install eduction rod 1, by nonmetal plug 6 protruded tube outside；Become heater 9；Then heater 9 is contained in non-metallic pipe 7, and non-metallic pipe two ends are fixed with heater, become non-metal shell electrothermal tube 11；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, and bends to U-shaped, 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, in unlimited one end, non-metallic pipe 8 and heater 9 are fixed, become non-metal shell electrothermal tube 11；Or in blind hole non-metallic pipe 8, loading electrothermal tube, described electrothermal tube is carbon fiber pipe or halide torch or non-metal shell electrothermal tube or dry combustion method electrothermal tube, and by the eduction rod 1 in blind hole one end, bending is turned back to the other end and is made eduction rod in same one end, becomes non-metal shell electrothermal tube 11.

Described non-metallic pipe 7 or 8, either blind hole pipe or straight pipe, first-selected quartz glass tube.

The invention has the beneficial effects as follows that electric hot water uses 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, and the also electrothermal tube of non-metal shell 7；

Fig. 2 is that one end has eduction rod, outside metal tube 5, and the also electrothermal tube of blind hole non-metal shell 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 to Fig. 9 is equipped with the electric hot water structural representation of non-metal shell electrothermal tube；

Figure 10 is existing electric hot water outline drawing；

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, non-metallic insulation spacer 10, non-metal shell electrothermal tube 11, chopper 12, metal or nonmetal water tank 15, shell 16.

Fig. 1 Fig. 2 is the employing non-metal shell electrothermal tube that one end filled in electric hot water 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. 3 is in blind hole non-metallic pipe 8, in Fig. 4 is straight-through non-metallic pipe 7, loads non-metal electric heating pipe 11, and described non-metal electric heating pipe refers to carbon fiber pipe or halide torch or non-metal shell electrothermal tube；Described dry combustion method electrothermal tube has heating wire in referring to metal tube, is insulated with metal pipe-wall by heating wire with magnesia powder；This kind of structure, the eduction rod in blind hole one end to bend and to turn back to the other end.

Fig. 5 to Fig. 9 is electric hot water structural representation, electric hot water power has several kilowatts to tens kilowatts, the quantity of electrothermal tube is many, can horizontal dress or perpendicular, water tank 15, built with electrothermal tube 11, is water outside it, the shell of this electrothermal tube is made up of nonmetal, there are heating wire and the isolation of water glass, never scaling in inside, never punctures；And domestic hot-water and heating hot water can be supplied.
