Utility model content
The purpose of this utility model is to provide the nonmetal glass electrothermic tube of nano electroheating film that a kind of quick heating, electric conversion efficiency are high, energy-conservation.
For realizing above-mentioned technical purpose, the electrothermal film heating pipe that this utility model provides adopts the following technical scheme that
A kind of nano electroheating pipe, its base material is quartz glass, it is characterised by, including cylindrical tube, one end open, one end is closed hemispherical, inboard wall of tube body frosting or internal outer wall frosting, being sprayed with nano electroheating film on inboard wall of tube body, body open ends is by telescopic high temperature resistant silica gel sealing shroud and high-temperature insulation plug, refractory seals glue and binding post composition.
Further, it is provided with circumferential clasp at tubular body, for the connection between wire and Electric radiant Heating Film, between Electric radiant Heating Film and circumferential clasp, scribbles ag paste electrode coating.
Further, it is provided with on circumferential clasp at tubular body and is welded with extraction wire, for connecting the connection between Electric radiant Heating Film and external power source line, draw and be welded with for convenient for wiring binding post between wire and external power connecting line.
Further, two electrodes at tubular body draw two wires respectively, overlap a glass insulated sleeve on long wire, it is prevented that the film plating layer of long conductor leading and glass tube walls or another annular steel ring and wire contacts thereof form short circuit.
Further, being provided with the telescopic resistant to elevated temperatures sealing sealing shroud for sealing and insulation plug in body open portion, the embedding refractory seals glue for sealing in the via of insulation plug and extraction wire, to seal and fixing extraction wire.
Further, described cylindrical tube is quartz glass tube, one of body is hemispherical head, other end is opening, the inwall of body or inside and outside wall frosting process, it is therefore intended that allow plated film under high temperature time, plated film body heating temperature is more stable, the nano electroheating film plated is more firm, and quality is more stable.
The beneficial effects of the utility model are:
1, because adopting heated by electrothermal film mode, heating surface is big, quick heating.2, electrothermal film electric thermal conversion efficiency is high.What 3, nano electroheating pipe adopted is nonmetallic quartz glass is base material body, owing to nonmetallic quartz glass is in the electrical heating process of water, it is not likely to produce incrustation scale, nano electroheating pipe is allowed to be always maintained at the electric conversion efficiency of a high position, thus opposing metallic electrothermal tube very easily produces incrustation scale in the electrical heating use procedure of water, electric conversion efficiency is gradually lowered, thus reaching opposing metallic electrothermal tube have bigger directly energy-conservation effect, the life-span is longer.4, adopting cylindrical tube structure, heating face is uniform.5, adopt body be quartz glass, quartz glass this as excellent insulator, use safer, further, since body adopt silica glass material, decrease metal ingredient make and, therefore more environmental protection.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this utility model is received and is added one preferred embodiment of heat pipe in fact, sill quartz glass tube, including one end open, the other end closes a hemispherical cylindrical tube 1, inboard wall of tube body is sprayed with nano electroheating film (nano electroheating film district 12), tube wall scribbles two ag paste electrode circles 3, electrode collar 3 is placed the elastic resistant to elevated temperatures steel ring snap ring 2 of band, steel ring snap ring welds an extraction wire 5, steel ring snap ring 2 and extraction wire 5 are mainly used in the power supply of nano electroheating film two electrode to be introduced, body open end device is useful in sealing shroud cartridge type high temperature resistant silicon gum cover 6, and use high temperature resistant silica gel sealing.The resistant to elevated temperatures telescopic silica gel sealing set 6 of sleeve body opening part device, resistant to elevated temperatures insulation plug 7 inlayed by silica gel sealing set, insulation plug is with two or more vias, in order to pass extraction wire 5, with the embedding of resistant to elevated temperatures fluid sealant 8 between plug 7 and wire 5, draw wire 5 with sealing with fixing, the wire 5 drawn outside plug, draw conducting wire end place welding upper connecting terminal 9, on binding post, then place pad 11 and screw 10, to facilitate the connection to external power cord.The inwall of cylindrical tube quartz ampoule or inside and outside wall do frosting and process.
This utility model is because adopting cylindrical tube structure, and heating face is uniform, and the life-span is long, spraying plating nano electroheating film in body, safety and environmental protection, and adopt heated by electrothermal film mode, heating surface is big, quick heating, electric conversion efficiency high, and nonmetal quartz glass tube body not easily scaling in the electrical heating process of water, contrast conventional metals electrothermal tube is more energy efficient, safer, the life-span is longer, the more environmental protection of nonmetal body.
Although this utility model is described as there is a degree of particularity, but current disclosure information please be understand only only with diagram.When not necessarily departing from impact spirit of the present utility model and when scope, when making and arranging the details of various parts, it is possible to take a series of change measure.
