The heating device comprises a transformer and a heating pipe which is electrically connected with the transformer and contacted with a to-be-heated solution. The heating device is characterized by further comprising a temperature controller and a temperature sensor, wherein the temperature controller is electrically connected with the transformer and the temperature sensor respectively, and the temperature sensor is contacted with the to-be-heated solution. Automatic constant-temperature heating can be performed through real-time temperature detection by the heating device, and the experimental accuracy is increased.
Description
Technical field
The utility model relates to a kind of use for laboratory heater.
Background technology
Heater is the conventional a kind of device in laboratory, at present, uses the most general heater to be comprised of transformer and electric heating coil, and it directly adds thermal response to oil bath pan.This type of heater is to regulate heating-up temperature by changing the voltage of transformer, uses safer.But the method is received voltage change and is usually caused the oil bath pan temperature of heating unstable, is difficult to control accurately reaction temperature, is unfavorable for carrying out smoothly of isothermal reaction, is therefore necessary this to improve.
Utility model content
The purpose of this utility model is, for above-mentioned defect of the prior art, to provide a kind of use for laboratory heater, and this heater can be realized automatic constant-temperature-heating, has increased the accuracy of experiment.
For realizing above-mentioned utility model object, the utility model has adopted following technical scheme: a kind of use for laboratory heater, described heater comprises transformer and the heating tube being mutually electrically connected with described transformer, described heating tube be heated solution phase and contact, it is characterized in that: described heater also comprises temperature controller and temperature sensor, described temperature controller is electrically connected mutually with described transformer and Temperature Detector respectively, described temperature sensor be heated solution phase and contact.
In addition, the utility model also provides following attached technical scheme:
Described temperature controller comprises power end, and described power end and civil power are electrically connected mutually.
Described transformer comprises transformer frequency response, and described transformer frequency response and described temperature controller are electrically connected mutually.
Described temperature sensor is thermocouple.
Described thermocouple comprises reference end, and described reference end and described temperature controller are electrically connected mutually.
Described thermocouple comprises measuring junction, described measuring junction with described in be heated solution phase and contact.
Than prior art, advantage of the present utility model is: a kind of use for laboratory heater is provided, it comprises transformer, heating tube, temperature controller and temperature sensor, and temperature controller is electrically connected mutually with transformer and Temperature Detector respectively, temperature sensor be heated solution phase and contact.Hence one can see that, and be heated solution and heat by heating tube, and the real time temperature that is heated solution detects by temperature sensor, finally by temperature controller, is processed, the temperature controller work of control transformer in real time simultaneously, thus control the work of heating tube.Therefore, this heater can be realized automatic constant-temperature-heating by real-time detected temperatures, has increased the accuracy of experiment.
Accompanying drawing explanation
Fig. 1 is the work schematic diagram corresponding to the use for laboratory heater of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
Figure 1 shows that the work schematic diagram of use for laboratory heater of the present utility model, as can be seen from Figure 1, this heater 2 is electrically connected mutually with mains supply 1, by mains supply 1, provide operating voltage for heater 2, therefore, the voltage of this power supply 1 is: AC220v ± 10%, or AC360v ± 10%.A wherein part for this heater 2 is inserted in oil bath pan 3, the oily (not shown) in oil bath pan 3 is heated to solution and carries out heat treated.
Particularly, this heater 2 comprises temperature controller 8, transformer 9, heating tube 10 and temperature sensor 11.Wherein, temperature controller 8 can be set upper and lower limit temperature value, and it has power end, control output end and sensor interface (not shown), transformer 9 adjustable output voltages, and it has transformer frequency response 13 and voltage output end (not shown), temperature sensor 11 is thermocouple 11, and this thermocouple 11 has measuring junction and reference end (not shown).
During connection, the power interface of temperature controller 8 and power supply 1 are electrically connected mutually, in order to operating voltage to be provided.The transformer frequency response 13 of transformer 9 is electrically connected mutually with the control output end of temperature controller 8, the voltage output end of transformer 9 and heating tube 10 are electrically connected mutually, heating tube 10 is arranged in oil bath pan 3, the oil in oil bath pan 3 is heated to solution phase and contacts and heat.The measuring junction of thermocouple 11 is arranged in oil bath pan 3, measures the oily temperature in oil bath pan 3, and reference end is electrically connected mutually with the sensor interface of temperature controller 8, and the temperature data that measuring junction is measured sends temperature controller 8 to.The all parts of this heater 2 is connected and is mutually electrically conducted by wire 15.
Operation principle of the present utility model is: due to transformer 9 adjustable output voltages (under this voltage, heating-up temperature is temperature required higher than experiment), and temperature controller 8 can be set upper and lower limit temperature value.Therefore, when the oily temperature in thermocouple 11 detects oil bath pan 3 surpasses the ceiling temperature of temperature controller 8 settings, the automatic disconnecting transformer power supply 13 of temperature controller 8, transformer 9 and heating tube 10 quit work; During lower limit temperature that the oily temperature in thermocouple 11 detects oil bath pan 3 is set lower than temperature controller 8, temperature controller 8 is connected again transformer frequency response 13 automatically, and transformer 9 and heating tube 10 are started working, and continue heating.Therefore, this use for laboratory heater 2 can be because the own voltage of extraneous voltage or transformer 9 be compared with the high temperature that causes temperature to surpass setting, realized automatic constant-temperature-heating, experiment is carried out smoothly, alleviated the artificial transformer that constantly regulates to control the complicated processes of temperature, reduced reaction temperature and controlled difficulty.
It is to be noted; above-mentioned preferred embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
