Description
Technical field
The utility model belongs to the heater field, is specifically related to a kind of coating machine diffusion pump electromagnetic eddy current heater, and the utility model, for the manufacturing of solar vacuum heat-collecting pipe, has obvious energy-saving effect compared to traditional heater.
Technical background
Produce the key equipment of vacuum heat collection pipe---the vacuum of coating machine obtains the capital equipment oil diffusion pump and constantly heats diffusion pump oil and its repeatedly vaporize/condensation is vacuumized, and the vapourizing temperature of diffusion pump oil is greatly about 170 ℃ of left and right.Original heater is resistance heater, the heating of employing resistance wire, conduct heat to the diffusion pump chassis by cross-ventilation, the heating diffusion pump oil, this mode makes heat run off in a large number in the cross-ventilation process, and the electric energy reactive power consumption is very large, and heat runs off ambient temperature is brought to impact, the short failure rate in useful life of resistance wire is high simultaneously, affects production efficiency, and use cost is high.Simultaneously resistance furnace also exist start-up time long environment for use require high, under high-temperature condition and in wet environment serviceability very fast life-span that descends short, under actual condition, the loose warm speed of resistance furnace is slow, equipment is long cooling time of stopping transport.Therefore designing the low life-span Chang'an of the fast thermal conversion efficiency highly energy-consuming of a kind of temperature rise entirely reaches the heater that maintenance rate is low and has very large meaning.
Summary of the invention
The purpose of this utility model is to provide a kind of coating machine diffusion pump electromagnetic eddy current heater
,it is simple in structure, and the heat efficiency is high, consumes energy low.
The technical solution of the utility model is: a kind of coating machine diffusion pump electromagnetic eddy current heater, comprise electromagnetic heating plate, pallet, and described electromagnetic heating plate is located on pallet, between described electromagnetic heating plate and pallet, is provided with heat-insulation layer; Described electromagnetic heating plate is provided with temperature detection sensor.
Described heat-insulation layer is selected heat-resisting asbestos.
Described temperature detection sensor is arranged on electromagnetic heating plate center and contact position, diffusion pump bottom, accurate with what guarantee to measure.
Described tray bottom is provided with louvre; Described pallet surrounding is provided with to pinch and hooks, for being connected and fixed of pinch groove with the diffusion pump bottom.
Whole device all is coated with the insulation resin cotton except bottom.
The operation of filming equipment has certain temperature requirement, if it is obviously unreasonable in heated condition all the time to have arrived uniform temperature, any material has cooling rate, the utility model device can be according to season or temperature bonding apparatus operating mode, laser heating and gap heating time are set, this is the arranged function on the control time, the constant function that also has heating-up temperature, central processing unit passes through the collection of temperature detection sensor institute feedback temperature and the computing of variations in temperature, automatically realize the constant control of heating, simultaneously on peripheral circuit in order to prevent fault, by the equipment touch-screen, limit heating-up temperature is set, once breaking down, heater can control its overtemperature heating.
beneficial effect:the utility model is for the heating of diffusion pump, it is fast that it has a temperature rise, the heat efficiency is high, consume energy low, start-up time is short, the advantages such as the fast safe and reliable life-span of loose warm speed is long, can realize automatic temperature-adjusting control according to actual process in actual use, in conjunction with working condition requirement, realizes automatic temperature rise time and temperature rise speed adjusting.
