The specific embodiment
As shown in Fig. 1,2,3,4, a kind of fused salt accumulated electric heater, comprise by fore shell 1, back cover 2, top cover 10, the housing that base plate 4 assembling of castor 3 consists of is installed, whole housing is stainless steel, right-hand member at the housing top cover is provided with guidance panel 5, power switch is arranged on guidance panel, be used for controlling the unlatching of electric heater; Microcomputer controller is used for the configuration switch machine time.Be air outlet 6 in the upper end of fore shell, air outlet is the shutter form, and wind enters from the base plate gap, via being flowed out by air outlet after interior air channel 7 or outer air duct 8.Be provided with wall bracket 11 on back cover, be used for fixedly electric heater.Be provided with blower fan 12 at organism bottom, it is arranged on blower fan fixed head 13.Body center is the fused salt case 15 that is full of fused salt 14, and the fused salt case is all also stainless steel, and fused salt case center is arranged side by side with two serpentine heating pipes 16, is fixed on the top cover of fused salt case, and heating power is respectively 800W.All be filled with rock wool heat-preservation material 17 in fused salt case front side and body front side, be used for preventing excessively scattering and disappearing and reducing the temperature of housing outer surface of heat, prevent from scalding.4 places are equipped with power line 18 at the housing base plate, and the power line overcoat has the glass fiber protective sleeve, prevent that high temperature from causing power line aging.Temperature controller 19 is installed on top cover 10, is used for monitoring and controlling the heating-up temperature of whole process.Be welded with reinforcement 20 in fused salt case 15 front and back sides, 7 stainless steel stiffening pieces have been evenly arranged take the electric heater center line as symmetry axis, ability for increasing fused salt case opposing thermal stress, be staggeredly arranged up and down, prevent from hindering flowing of fused salt, described blower fan 12 is opened when large or temperature of molten salt reduces in thermic load, strengthen the heat convection of electric heater and room air, to meet the demands.Wind deflector 9 is used for regulating the flow direction of wind, and when large or temperature of molten salt was low when thermic load, wind deflector 9 pushed outer air duct 8 places, air channel 7 in opening, and when less or temperature of molten salt was higher when thermic load, wind deflector 9 pushed 7 places, interior air channel, opens outer air duct 8.Heating tube 16 is at 20:00---and open in the second day 08:00 time, be used for the heating fused salt.08:00---20:00 stops in the time by day, utilizes the heat that fused salt renews to heat.
Operation principle:
Open switch, switch on power, set the electric heater open and close time by the microcomputer controller on guidance panel, open the heating tube switch, heating tube is started working, constantly emit heat, will to be increased to preset temperature maximum heating temperature commonly used be 450 ℃ of left and right to temperature of molten salt within the default available machine time, and this moment, heating tube quit work automatically.As time goes on, fused salt is externally heat radiation constantly, when early stage, temperature of molten salt was higher, mainly the heat loss through radiation by the hull outside surface heats, if thermic load is large or when needing quick rising indoor temperature, can open blower fan, realize above purpose by the heat convection that strengthens air.when temperature is reduced to preset temperature, open blower fan, wind deflector is pushed interior air channel, outer air duct is started working, outer air duct is near hull outside, the interior air channel of temperature decreases, air enters from the space of housing bottom, after being heated, outer air duct flows out from air outlet, heat is taken to indoor, realize the purpose of heating, when temperature further reduces, wind deflector is pushed the outer air duct direction, start working in interior air channel, interior air channel is near the fused salt case outside, temperature increases to some extent than outer air duct, air enters from the space of housing bottom equally, after being heated, interior air channel flows out from air outlet, heat is taken to indoor, realize the heating purpose.The rock wool heat-preservation of filling between fused salt case and housing is cotton, has both prevented that the too fast of heat scattered and disappeared, and also the hull outside surface temperature is reduced to the temperature that human body can bear, and prevents the generation of scald accident.
