Description
Technical field:
The present invention relates to a kind of water-storage electric heater and heat-generating pipe preparation method.
Background technology:
The heat-generating pipe of existing electric heater is all install metal electric heated filament in metal tube, then with quartz sand, metal tube and metal electric heated filament is kept apart, and then uses insulating materials shutoff metal tube two ends, finally metal tube is bent to different shapes.This heat-generating pipe is when adding the water in hot water storage tank, calcium carbonate is easy to be deposited on heat-generating pipe surface, the metal of water and heat-generating pipe is kept apart, hinder the heat transmission feedwater of heat-generating pipe, cause the metal electric hot-wire temperature in heat-generating pipe too high, metal electric heated filament is oxidized too quickly, and metal electric heated filament attenuates, resistance becomes large, power diminishes.Metal heat-generating pipe is easy to get rusty, and the contact area of metal heat-generating pipe outer surface and water is too little, is not easy heat to pass.The cost of manufacture of metal heat-generating pipe is high, and the metal electric heated filament of metal heat-generating pipe is easy in use blow.In order to prevent metal heat-generating pipe from getting rusty, water storage tank is built with magnesium rod; After the corrosion of magnesium rod is complete, just start corrosion metals heat-generating pipe.
Summary of the invention:
The metal heat-generating pipe that the present invention solves existing water-storage electric heater gets rusty easily and fouling, has heated uneven defect.
Water-storage electric heater of the present invention is primarily of water storage tank, shell, heat-generating pipe, water inlet pipe, outlet pipe, safety valve, mixed water valve and temperature detect switch (TDS) or temperature sensor composition.Water storage tank divides upper and lower two parts, and the dividing plate of centre separates.Dividing plate is welded on water storage tank circular arc wall, has the gap of a fixed width between the two ends upright side walls of dividing plate and water storage tank.Heat-generating pipe is arranged in the latter half of water storage tank.Heat-generating pipe is ion concussion heat-generating pipe, recrystallized silicon carbide heat-generating pipe or carbon fibre heat-generating pipe.Water pump draws water from the latter half of water storage tank during heat-generating pipe electrified regulation water, then inner from hollow heat-generating pipe entrance press-in heat-generating pipe, then exports out from the heat-generating pipe other end, the heat that heat-generating pipe produces is taken away.Ion concussion heat-generating pipe, recrystallized silicon carbide heat-generating pipe and carbon fibre heat-generating pipe are all ceramic heating tubes, and can not get rusty, surface is non flouling behaviour also.
The preparation method of ion concussion heat-generating pipe is as follows: with ceramic clay work pipe; After the drying of ceramic mud embryo pipe, mutually isolated array metal sheet or carbon fibre film fire pole plate L pole plate and N pole plate is stained with successively, above the fiery pole plate then covering sheet metal or carbon fibre film with ceramic mud and zero pole plate outside ceramic mud embryo pipe.In groove inside the ceramic mud embryo pipe that the fiery pole plate L of sheet metal or carbon fibre film is corresponding with the clearance position between zero pole plate N, shallow embedding has graphite bar or carbon fibre wiregrating pole and earth polar.With carbon fibre as metal polar plate or carbon fibre film fire pole plate and the lead-in wire in zero pole and graphite bar or carbon fibre wiregrating pole and earth polar, then mix ceramic flange and pipe screw thread ceramic joint, then put into furnace sintering.Take out the finished product sintered, polish off the pottery that graphite bar or carbon fibre wiregrating pole and surface, earth polar are shallow.
Connect the live wire of civil power to the fiery pole plate of ion concussion heat-generating pipe, zero pole plate connects the zero line of civil power.Receive the positive pole of low tension to the grid of ion concussion heat-generating pipe, the negative pole of low tension is received in earth polar.The ion concussion grid of heat-generating pipe and earth polar connect low tension, make ion shake water power in heat-generating pipe from.The fiery pole plate of ion concussion heat-generating pipe and zero pole plate connect the alternating electric field that civil power produces, and the ion that ion shakes in heat-generating pipe is shaken, and add the water in thermion concussion heat-generating pipe.
The preparation method of recrystallized silicon carbide heat-generating pipe is as follows: with ceramic clay work pipe, after the drying of ceramic mud embryo pipe, the crystalline silicon carbide silicon thin film of one deck polyvinyl alcohol as binding agent is covered, on the inner surface and outer surface crystalline silicon carbide silicon thin film that stick to ceramic mud pipe respectively as going between with two carbon fibre lines in one end of the inner surface of ceramic mud pipe, outer surface and ceramic mud pipe.To cover one deck pottery mud outside the ceramic mud pipe of crystalline silicon carbide silicon thin film covering, then mix ceramic flange and pipe screw thread ceramic joint, then put into furnace sintering.
The preparation method of carbon fibre heat-generating pipe is as follows; With pottery clay work pipe, after the drying of ceramic mud embryo pipe, cover the carbon fibre film of one deck polyvinyl alcohol as binding agent in one end of the inner surface of ceramic mud pipe, outer surface and ceramic mud pipe, stick to respectively on the carbon fibre film of ceramic mud pipe inner surface and outer surface as lead-in wire with two carbon fibre lines.To cover one deck pottery mud outside the ceramic mud pipe of carbon fibre film covering, then mix ceramic flange and pipe screw thread ceramic joint, then put into furnace sintering.
