Abstract
During the production process of traditional Chinese medicine lotion, steam heating is adopted in general, and heat is transferred to the top from the bottom part; in a traditional temperature monitoring method, a temperature sensor probe is directly inserted into a tank body, and process control is performed according to a temperature value, but judging whether the temperature in the large-capacity traditional Chinese medicine extracting tank meets the design requirements or not simply by a temperature gauge is not accurate. The invention provides a technical method, which is capable of accurately reflecting the change condition of the temperature in the tank and ensuring the accuracy of temperature data acquired by a computer automatic control system, thereby, the temperature rise and heat preservation processes of a medicine are controlled. Firstly, the lower part and the upper part of the tank body are respectively provided with a temperature sensor. Finally, temperature proportion integration differentiation (PID) regulation control is performed according to the temperature variation of the temperature sensor in the liquid at the lower part in the tank; during the temperature rise process, the boiling point of the liquid in the tank is judged through judging and comparing the consistency of the temperature of the liquid at the lower part of the tank body with the temperature of the liquid at the upper part of the tank body; and when the temperature reaches a set value, the temperature rise process is ended to switch to a heat preservation stage.
Description
Technical field
The present invention relates to the fluid temperature automatic control technology, specifically is traditional Chinese medicine extraction jar temperature autocontrol method.
Background technology
In recent years; Along with the development of application demand and the raising and the widespread use of automatic control technology; The Chinese medicine quality of production hierarchy of control more and more receives the attention of medicine prison departments at different levels and enterprise; Drop into great amount of manpower and material resources and financial resources and carry out the transformation of quality of production monitoring technique, to guarantee the tcm product quality of stability.
In the production run of Chinese medicine washing lotion; It generally all is Steam Heating; Heat up transmits from the bottom; Consistance how to monitor jar interior temperature can directly influence product quality, and the good heating process of boiling point correct handling how to judge pot liquid also is a problem demanding prompt solution to the switching of heat preservation method.Traditional method is directly temperature sensor probe to be inserted in the tank body; Through judging whether temperature reaches setting and carry out technology controlling and process; But be to be difficult to judge the medial temperature in this big volume extractor of traditional Chinese medicine extraction jar with a thermometer merely; To the boiling point judgement in the intensification control in traditional Chinese medicine extraction stage is quite difficult, also is inaccurate.
Summary of the invention
The purpose of this invention is to provide a kind of technical method, make it can fully reflect a jar interior variation of temperature situation, can accurately judge the boiling point of jar interior medicine simultaneously.Guarantee the accuracy of computer automatic control system collecting temperature data like this, judged the boiling point of medicine simultaneously, thereby accomplished the temperature-rise period of medicine smoothly.
The two temperature sensor temperature-controlled process of traditional Chinese medicine extraction jar proposed by the invention are:
1) temperature sensor is installed in traditional Chinese medicine extraction tank bottom, is guaranteed that in the traditional Chinese medicine extraction process, this thermometer is positioned under the pot liquid face.
2) temperature sensor is installed in the top of traditional Chinese medicine extraction tank body, is guaranteed in the traditional Chinese medicine extraction process, this thermometer is positioned on the pot liquid face and is not submerged.
3) in the traditional Chinese medicine extraction temperature-rise period, the PID that the temperature variation of the temperature sensor through the bottom carries out control system regulates, thus the consistance of medial temperature in guaranteeing jar.
4) in temperature-rise period, judge the boiling point of pot liquid through the consistance of temperature and tank body top liquid level temperature in the liquid of judgement comparison tank body bottom, thereby finish temperature-rise period, change holding stage over to.
Embodiment
Below in conjunction with embodiment the present invention is further described.
At first, according to method of the present invention, the mounting temperature sensor in the tank body bottom, mounting temperature sensor on tank body top.
At last, in traditional Chinese medicine extraction jar traditional Chinese medicine extraction process, carry out temperature PID according to temperature sensor temperature variation in the bottom liquid in the jar and regulate control; In temperature-rise period, judge the boiling point of pot liquid through the consistance of temperature and tank body top liquid level temperature in the liquid of judgement comparison tank body bottom, thereby finish temperature-rise period, change holding stage over to.
Claims (1)
1. two temperature sensor control methods of traditional Chinese medicine extraction jar is characterized in that:
1) a kind of technical method is provided, makes it fully reflect a jar interior variation of temperature situation, accurately judge jar boiling point of interior medicine simultaneously.
2) temperature sensor is installed in traditional Chinese medicine extraction tank bottom, is guaranteed that in the traditional Chinese medicine extraction process, this thermometer is positioned under the pot liquid face.
3) temperature sensor is installed in the top of traditional Chinese medicine extraction tank body, is guaranteed in the traditional Chinese medicine extraction process, this thermometer is positioned on the pot liquid face and is not submerged.
4) in the traditional Chinese medicine extraction temperature-rise period, the PID that the temperature variation of the temperature sensor through the bottom carries out control system regulates, thus the consistance of medial temperature in guaranteeing jar.
5) in temperature-rise period, judge the boiling point of pot liquid through the consistance of temperature and tank body top liquid level temperature in the liquid of judgement comparison tank body bottom, thereby finish temperature-rise period, change holding stage over to.
