Description
The present invention relates to a kind of improved calibration cell, be used at-30 ℃ of-300 ℃ of warm areas calibratings and calibration first-class and second-class standard thermometer, semiconductor point temperature meter, thermal resistance and thermopair etc.
The present calibration cell of producing, its frid (groove drum and big panel) is to make with chromium plating steel plate, oxygen polarization aluminium sheet or corrosion resistant plate, perhaps make big panel with above material, making groove drum with glass assembles, plate forming need stretch or weld, and exists that cost height, processing difficulties are perishable, rapid heat dissipation, warm field stability is poor, serviceable life short, the problem of warm area narrow range.Its insulation material adopts shortcomings such as polyfoam, expanded perlite or glass fibre, these materials exist the cost height respectively, coefficient of heat conductivity is big, and are perishable, easy aging, overweight and harmful.It adds Thermal temperature controller a kind of power only is set, and it is slow excessively to exist firing rate, difficult control of temperature, thereby cause the electric deficiency of expense consuming time.
In CN85205068, disclosed a kind of cell body of making of copper-stainless steel composite material, with metal support as panel,, handle as muff with aluminosilicate fiber cotton, adopt " the heat pipe type glass-stem thermometer demarcation/calibrating calibration cell " of heat pipe principle design by external control desk.Can demarcate or the calibrating use at 75 ℃ of-250 ℃ of warm areas for glass-stem thermometer.Though solved the anticorrosion and pollution problem of calibration cell container, also exist difficulty in process, cost costliness, warm area is narrow, serviceable life is short and dangerous deficiency such as reliable.
The objective of the invention is to provide a kind of wide warm area, multi-usage, quick heating, insulation strong, be convenient to operate, manufacturing process is simple, cost is low, anti-rotten power is strong, long service life and safe and reliable calibration cell.
The present invention is achieved in that is equipped with the muff made with the rock wool material, is made into integration frid, stirring apparatus, well heater and thermostat with stupalith in support, handle well heater and thermostat by external control desk, and handle stirring apparatus by motor and belt.In use can be according to the calibrating and the needs of calibration, by low (30 ℃-0 ℃), in (room temperature-95 ℃), height (50 °-300 ℃) temperature in the frid container, add dry ice (alcohol), water or oily respectively as medium.By the Fast Heating of well heater, make medium reach required critical temperature, keep equilibrium temperature by controller then, start stirring apparatus, medium is sucked the plate hole from bucket in the bucket, from the hole of bucket lower plate, discharge outside the bucket again, form medium in the inside and outside rotation circulation of bucket.Thereby make the vertical temperature field error of calibration cell be not more than 0.005 ℃; Level temperature field is not more than 0.005 ℃; Temperature field stability: in △ t0.07 ℃/10 minutes.Thereby make calibration cell reach wide warm area, multi-usage, quick heating, insulation strong, be convenient to operate, manufacturing process is simple, cost is low, anti-rotten power is strong, long service life and safe and reliable purpose.
Another kind of scheme of the present invention is: by on the basis of first kind of scheme, control desk is contained on the support.Can make so not only that calibration cell reaches wide warm area, multi-usage, technology is simple, cost is low, long service life, and can avoid lead between control desk and the operator's console, under the trampling of people and Che, leakage is cut off the power supply and is caused and stop work and personal injury, reaches more safe and reliable purpose.
The present invention can also realize like this: adopt power be 1000-2000 watt well heater and power be 300-600 watt thermostat, when calibration cell starts, use earlier powerful well heater, make medium reach required critical temperature fast, keep equilibrium temperature by thermostat then.Initial firing rate is speeded more than 4 times, and make thermostat reduce the frequent number of times of opening, stop, reach the power saving that saves time, the purpose of being convenient to operate.
The present invention's technical scheme preferably is: control desk is made up of block terminal and control panel two parts.Control panel is contained in the place that rack surface is convenient to operate, block terminal is contained in internal stent, make calibration cell neat and artistic.
Best techniques scheme of the present invention is: block terminal is contained in the below of other parts of internal stent, control panel is contained in the top of support lateral surface, make calibration cell beautiful and clean, and be convenient to operation.
The present invention is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is divided into two-part cross-sectional schematic for control desk of the present invention and operator's console.
Fig. 2 is contained in half section synoptic diagram on the control stand for control desk of the present invention.
With reference to Fig. 1 first embodiment of the present invention is described: the muff made from the rock wool material 3 is housed in support 6; Being made into integration groove internal diameter * height with stupalith is foursquare frid 2 for 200 * 510 millimeters of φ, upper plate; Handle stirring apparatus 1 with external control desk 5 by motor 4 and belt 11.Stirring apparatus 1 is by small panel, the bucket upper plate, bucket, the bucket lower plate, belt pulley, axle sleeve, shaft and blade, use double-screw bolt, cover and nut assemble, outside the bucket of small panel and bucket upper plate in a week, needs by calibrating and calibration, have the jack of many different sizes, 1500 watts well heaters 7 are made " U " type, be contained in frid 2 containers, outside the bucket of stirring apparatus 1, pass a barrel upper plate, be fixed on the small panel, 500 watts of controllers 9 are made screw type, be contained in the bucket, pass a barrel upper plate round shaft, be fixed on the small panel, handle well heater 7 and controller 9 by external control desk 5.
With reference to Fig. 2, second embodiment of the present invention is described: change control desk into block terminal 8 and control panel 10 two parts.Block terminal 8 is contained in support 6 inner other parts belows, and control panel 10 is contained in the top of support 6 lateral surfaces.In addition, other parts are fully identical with first embodiment.
See figures.1.and.2, method of operating of the present invention is described: according to the needs of calibrating and calibration, in frid 2 containers, add certain medium, electric contact thermometer is inserted in the jack of small panel, the output line of electric contact thermometer and the control circuit of calibration cell are linked, energized is transferred to contact pilotage on the temperature that will control by the magnet steel of rotation electric contact thermometer.By control panel 10(control desk 5) handle well heater 7 and be rapidly heated and handle stirring vane and rotate, promote the medium circulation rotational flow in the container.With standard thermometer with inserted by the object examined and determine in the jack of small panel, when temperature will reach desired value, start thermostat 9, close well heater 7, when equitemperature is raised to desired value, can examine and determine and calibration.
Use the said Multipurpose thermostatic bath of the present invention, compare with " heating tube-type glass thermometer-calibrating/checking constant-temp. oven " with general thermostat, have following significant effect: 1. flat-temperature zone wide (30 ℃-300 ℃), it is multiplex to reach a groove. 2. heat-insulating property is strong, and programming rate speeds more than 4 times. 3. antiseptic property is strong, long service life. 4. clean and tidy, attractive in appearance, safe, reliable. 5. manufacturing process is simple, and cost is more than 80%.
