Abstract
The utility model discloses a precise oven which comprises an oven body and a temperature control device. The temperature control device comprises a heating plate, a circulating fan, a temperature sensor, a solid-state relay and a PID precision meter. The PID precision meter is communicated with the heating plate through the solid-state relay and communicated with the circulating fan and the temperature sensor. When the precise oven is used, a to-be-dried test-piece is put into the precise oven, and the PID precision meter is started. The precision meter can automatically receive signals from the temperature sensor, processes the signals to obtain a current temperature and compares the current temperature with a preset temperature. If the current temperature is lower than the preset temperature, the PID precision meter starts the heating plate through the solid-state relay to heat up; if the current temperature in the oven is higher than the preset temperature, the PID precision meter sends shut-off signals to the sold-state relay to prevent the heating plate from working. The temperature is naturally lowered, during the whole experimental process, the PID precision meter controls the circulating fan to rotate, enables temperatures of parts of the oven to uniformly change and improves experimental accuracy.
Description
Technical field:
The utility model relates to a kind of temperature-control adjustment device, particularly relate to a kind of can automatic control stuff box in the accurate baking oven of temperature.
Background technology:
More and more higher along with people to environmental requirement, adopting miniature instrument equipment to carry out industrial experiment research has become the development inexorable trend.At present, the miniature instrument device emerges, but in process of experimental, the operations such as heating, constant temperature still adopt traditional mode of heating to carry out, and there are the shortcomings such as heat transfer is inhomogeneous, the constant temperature precision is not high, experimental data is inaccurate, service life is short in operation like this.
The utility model content:
Technical problem to be solved in the utility model is: provide a kind of and conduct heat evenly, temperature control precision is high, experimental data is accurate, the accurate baking oven of long service life.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of accurate baking oven comprises baking oven casing and attemperating unit, and described attemperating unit comprises heating plate, circulating fan, temperature sensor, solid-state relay and PID precision instrument, and described PID precision instrument is connected with heating plate by solid-state relay.
Described PID precision instrument is connected with circulating fan.
Described PID precision instrument is connected with temperature sensor.
During use, test specimen to be dried by the fire is put down gently in accurate baking oven, good seal is opened the PID precision instrument, sets assigned temperature, and the PID precision instrument will be regulated the temperature in baking oven automatically, makes its balance and stability.
Its operation principle is as follows: the PID precision instrument can receive the signal from temperature sensor automatically, Current Temperatures is obtained in processing, allows it follow the temperature of setting to compare, if lower than design temperature, the PID precision instrument is opened heating plate by solid-state relay, is used for heating up; If in current baking oven, temperature is higher than design temperature, the PID precision instrument sends cut-off signal to solid-state relay, allows heating plate quit work, naturally cooling.In whole experimentation, the PID precision instrument is being controlled circulating fan always and is being rotated, and makes the temperature even variation of each several part in baking oven, improves experimental precision.
Good effect of the present utility model is as follows:
The utility model is the accurate instrument of modified, can automatically regulate temperature in baking oven, to be used for scientific experiment and other association area, rational in infrastructure, convenient durable, temperature control is more accurate, it has adopted heating plate in baking oven, be more conducive to so the even transmission of heat, temperature in each little space is obtained as far as possible be equal to, make its control that is more conducive to the PID precision instrument, precision has largelyr than before and improves.
Use the utility model in whole process of the test, all operations is all to control by the PID precision instrument, automaticity is high, easy and simple to handle, add circulating fan, the product heat balance time is short, temperature fluctuation is little, good uniformity causes result of the test more accurate, is fit to very much and can satisfies vast demander.
The utility model conducts heat evenly, and temperature control precision is high, and compact conformation is handsome in appearance, saves the energy, and long service life etc. are to be applicable to the kinds of experiments scientific domain directly or the precision instrument of auxiliary heating.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the control principle schematic diagram of attemperating unit in Fig. 1.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
Referring to Fig. 1 and Fig. 2, a kind of accurate baking oven, comprise baking oven casing 1 and attemperating unit, described attemperating unit comprises heating plate 2, circulating fan 3, temperature sensor 4, solid-state relay 5 and PID precision instrument 6, described PID precision instrument 6 is connected with heating plate 2 by solid-state relay 5, PID precision instrument 6 is connected with circulating fan 3, and PID precision instrument 6 is connected with temperature sensor 4.
During use, object to be measured is put into accurate baking oven gently, good seal is opened instrument, sets assigned temperature, and instrument will be regulated the temperature in baking oven automatically, makes its balance and stability.
