In the figure, 1 is a steam regulating valve, 2 is a pneumatic switch valve, 3 is a first heating jacket, 4 is a second heating jacket, 5 is a heating coil, and 6 is a temperature transmitter.
Detailed Description
The present invention will be described in further detail with reference to examples and embodiments.
As shown in figure 1, a heating device capable of keeping micro-boiling in a traditional Chinese medicine extraction tank in the extraction process structurally comprises a steam regulating valve 1, a pneumatic switch valve 2, a first section of heating jacket 3, a second section of heating jacket 4, a heating coil 5 and a temperature transmitter 6, wherein the steam regulating valve 1 and the pneumatic switch valve 2 are installed on a steam inlet pipeline on the side face of the tank body of the stainless traditional Chinese medicine extraction tank, the first section of heating jacket 3 and the second section of heating jacket 4 are adjacently arranged on the outer side of the tank body of the traditional Chinese medicine extraction tank up and down, the heating coil 5 is arranged at the bottom of the inner side of the tank body of the traditional Chinese medicine extraction tank, and the tank body of the traditional Chinese medicine extraction tank is also provided with the temperature transmitter 6.
The steam regulating valve 1 is positioned on a steam main pipe of the traditional Chinese medicine extracting tank body which is externally connected with the steam tank.
The steam main pipe is respectively connected with a first section of heating jacket 3, a second section of heating jacket 4 and a heating coil 5 through steam inlet branch pipes, and 3 pneumatic switch valves 2 are respectively arranged on the 3 steam inlet branch pipes.
The temperature transmitter 6 is positioned at two sides of the middle lower part of the traditional Chinese medicine extracting tank body.
According to the structure, during operation, a steam regulating valve is arranged on a steam main pipe of the traditional Chinese medicine extracting tank, and the traditional Chinese medicine extracting tank further comprises a steam inlet valve (a pneumatic switch valve) of the first section of heating jacket, a steam inlet valve of the second section of heating jacket and a steam inlet valve of the third section of heating coil.
In the temperature rising process, the first section of heating jacket, the second section of heating jacket and the third section of heating coil are opened for heating, meanwhile, the heating rate is controlled by the adjusting valve, after the temperature approaches the heat preservation temperature, the steam inlet valve of the first section of heating jacket is closed, the second section of heating jacket and the third section of heating coil are used for heating, when the heat preservation and the micro-boiling state is reached, only the heating mode of the bottom heating coil is adopted, two temperature transmitters are arranged in the extraction tank at the same time, and the error is reduced by double-point detection temperature.
