Abstract
The utility model discloses a double thermocouple temperature measuring device which is arranged in a container and comprises a first thermocouple, a second thermocouple, a fixation frame and a PLC. The first thermocouple and the second thermocouple are fixed on the fixation frame. The length of the first thermocouple is less than the length of the second thermocouple. The first thermocouple and the second thermocouple are connected with the PLC controller. The fixation frame is fixed with the container. The double thermocouple temperature measuring device provided by the utility model has the advantages of simple structure and accurate measuring, can timely find that sediments or insoluble substances are excessive and gives an alarm prompt.
Description
Technical field
The utility model relates to temperature measuring apparatus in a kind of Chemical Manufacture, relates in particular to a kind of double-thermocouple temperature measuring apparatus.
Background technology
In Chemical Manufacture, the temperature of reaction solution generally detects by thermopair, but there iing the productive unit that sediment generates or insolubles participates in, sediment or insolubles are constantly accumulated along with the growth of production time, to a certain degree thermocouple probe can be covered afterwards, sedimentary temperature and solution temperature have certain difference, and this can cause the error of temperature detection, to production control, brings some problems; In producing at present, the accumulation of General Requirements sediment or insolubles can not be too much, and the thermopair of single is used in temperature measuring, the accumulating amount of sediment or insolubles is to be judged according to knowhow by staff, when thermopair is capped, again coverture is cleared up, but this exists certain hysteresis quality and instability, be unfavorable for the accurate control of production and the stable operation of technique.
Summary of the invention
The utility model is in order to solve when measurement has the production run temperature that sediment generates or insolubles participates in, the easy precipitated thing of thermopair or insolubles cover and affect measuring accuracy, affect the problem that production control and process stabilizing carry out simultaneously, provide a kind of simple in structure, measure accurately, can find in time that sediment or insolubles too much will affect the double-thermocouple temperature measuring apparatus of production phenomenon.
To achieve these goals, the utility model is by the following technical solutions: double-thermocouple temperature measuring apparatus, be arranged in container, comprise the first thermopair, the second thermopair, fixed mount, PLC controller, described the first thermopair, the second thermopair are fixed on fixed mount, the measuring position of described the first thermopair is higher than the second thermocouple measurement position, and described the first thermopair, the second thermopair are connected with PLC controller, and described fixed mount and container are fixed.The Chemical Manufacture of carrying out in container, sediment or insolubles generally all can accumulate in container bottom, this programme adopts double-thermocouple to measure solution temperature, one of them measuring vessel middle part temperature, another measuring vessel bottom temp, measure the thermopair of bottom temp can first precipitated thing or insolubles affect, cause and measure temperature generation deviation, the thermopair of now measuring middle part temperature is not yet affected, now PLC controller can judge according to the difference of two thermopairs the accumulation situation of sediment or insolubles, and alarm is processed sediment or insolubles.
As preferably, the length of the first described thermopair is less than the second thermopair.For convenience of installing and using, fixed mount can adopt slab construction, and the two kinds of thermopairs of selecting that one is long and the other is short are respectively as the first thermopair, the second thermopair; The concrete length of thermopair is set according to producing actual liquid level control.
Therefore, the utlity model has following beneficial effect: (1) is simple in structure; (2) measure accurately; (3) can find in time the too much also alarm of sediment or insolubles.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1, the first thermopair 2, the second thermopair 3, fixed mount 4, PLC controller
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment as shown in Figure 1, double-thermocouple temperature measuring apparatus, be arranged in container, comprise the first thermopair 1, the second thermopair 2, fixed mount 3, PLC controller 4, the first thermopair 1, the second thermopair 2 are fixed on fixed mount 3, the length of the first thermopair 1 is less than the second thermopair 2, the first thermopairs 1, the second thermopair 2 is connected with PLC controller 4, and fixed mount 3 is fixed with container.
Specific implementation process is, during work, the first shorter thermopair 1 of length remains in solution, can measure accurately the temperature of solution, for technology controlling and process provides reference, the second thermopair 2 that length is long is put compared with deep-seated at solution, when sediment or insolubles are when less, its temperature measuring result is consistent with the first thermopair 1 measured value, but when sediment or insolubles cover the probe of the second thermopair 2, its temperature measuring result and the first thermopair 1 measured value produce deviation, now by PLC controller 4, send warning, staff carries out the cleaning of sediment or insolubles, after processing, produce and continue stable operation.
Claims (2)
1. a double-thermocouple temperature measuring apparatus, be arranged in container, it is characterized in that, comprise the first thermopair, the second thermopair, fixed mount, PLC controller, described the first thermopair, the second thermopair are fixed on fixed mount, the measuring position of described the first thermopair is higher than the second thermocouple measurement position, and described the first thermopair, the second thermopair are connected with PLC controller, and described fixed mount and container are fixed.
