Description

Technical Field

[0001] The utility model belongs to the field of medicine production equipment, and specifically relates to an automatic ethanol preparation system. Background Art

[0002] Ethanol (English: Ethanol, structural formula: CH3CH2OH) is a type of alcohol and the main component of wine, so it is also called alcohol. It is a renewable substance. Ethanol is flammable and is a commonly used fuel, solvent and disinfectant. It is also used to make other compounds. Ethanol is a very good solvent that can dissolve many inorganic and organic substances. Therefore, ethanol is often used to dissolve plant pigments or medicinal ingredients. Ethanol is also often used as a solvent for reactions, so that both organic and inorganic substances participating in the reaction can be dissolved, increasing the contact area and increasing the reaction rate.

[0003] Ethanol is widely used in the field of pharmaceutical production. It can be used as a solvent to extract, separate, and purify active substances. According to the different physical properties of the active substances and the different polarity of the ethanol concentration, different concentrations of ethanol need to be selected to treat the target substance to obtain the expected target product. In the process of pharmaceutical production and manufacturing, the manual preparation of ethanol will affect the quality stability of the prepared ethanol due to environmental factors, the concentration and temperature of the prepared ethanol, human operation factors, etc. As the main solvent, the concentration and quantity of ethanol are not stable, which often affects the quality and yield of the product. If there is a device that can automatically prepare ethanol, it will stabilize the concentration and quantity of the prepared ethanol, thereby ensuring the quality of the product.

The high-efficiency mixer 5 can adopt all equipment in the prior art that can achieve uniform mixing of solutions. The outlet of the high-efficiency mixer 5 is connected to the inlet of the finished product storage tank 4 through the finished product ethanol solution pipeline, and the finished product ethanol solution pipeline is also provided with a flow meter 61. Of course, this automatic ethanol preparation system should also be equipped with a controller, which is connected to the signals of each delivery pump 64 and control valve 63 in the system, so as to control the start and stop and working frequency of the delivery pump 64. At the same time, the controller signal is connected to each concentration meter, liquid level meter, and flow meter in this preparation system to collect parameters such as the concentration of the ethanol solution in each tank, the liquid level height, the temperature of the ethanol solution, and the flow rate of the ethanol solution through the pipeline. Ultimately, the controller can control the flow rate of the ethanol solution in each pipeline; before preparing the ethanol solution, the user must input the concentration, quantity, and preparation speed of the ethanol solution to be prepared.

[0024] Embodiment 2

[0025] like Figure 2 As shown, this embodiment is an optimized form of the automatic ethanol preparation system proposed in the present invention, including three ethanol solution storage tanks to be prepared, a high-efficiency mixer 13, a finished product storage tank 11, a concentrated ethanol solution recovery tank 7 and a shell-and-tube heat exchanger 12; in this embodiment, the three ethanol solution storage tanks to be prepared include a concentrated ethanol solution storage tank, a dilute ethanol solution storage tank and a dilute ethanol solution storage tank.

[0026] like Figure 3 As shown, a concentrated ethanol solution recovery tank 7 is provided in the ethanol preparation system. Since waste liquid or waste gas containing ethanol may be generated in some processes of pharmaceutical production. These waste liquids or waste gases can be collected and processed by a specific recovery system to recover the ethanol therein. The recovered ethanol can be effectively separated from other substances by distillation or other separation techniques, and the ethanol with higher purity is obtained and then transported to the concentrated ethanol solution recovery tank 7. The outlet of the concentrated ethanol solution recovery tank 7 is connected to the inlet of the concentrated ethanol solution storage tank through a concentrated ethanol solution delivery pipeline 71, and the concentrated ethanol solution delivery pipeline 71 is provided with a variable frequency delivery pump 72, a pneumatic control valve 73 and a diaphragm pressure gauge 74 connected to the controller signal, so that the controller can control the concentrated ethanol solution in the concentrated ethanol solution recovery tank 7 to be added to the concentrated ethanol solution storage tank.

The circulation pipeline 81 is provided with a variable frequency delivery pump 83, a diaphragm pressure gauge and a pneumatic control valve 82. The concentrated ethanol solution storage tank is provided with an ethanol concentration meter for detecting the internal ethanol concentration, a thermometer for detecting the internal ethanol solution temperature, and two tuning fork level switches respectively arranged at a high position and a low position in the ethanol solution storage tank. When the ethanol liquid level exceeds the high-position tuning fork liquid level switch and is lower than the low-position tuning fork liquid level switch, the controller can control the concentrated ethanol solution recovery tank 7 to inject concentrated ethanol solution into the concentrated ethanol solution storage tank 8 according to the switch signal, thereby ensuring that the solution level in the concentrated ethanol solution storage tank is within a set range. The concentrated ethanol solution storage tank is connected to the high-efficiency pipeline mixer 13 through the ethanol solution pipeline 86 to be prepared, and the ethanol solution pipeline 86 to be prepared is provided with a variable frequency delivery pump 87, a control valve 88, a diaphragm pressure gauge and a mass flow meter 89, so that the concentrated ethanol solution is delivered to the high-efficiency pipeline mixer 13.

The inlet and outlet ends of the high-efficiency pipeline mixer 13 are both provided with diaphragm pressure gauges to monitor the pressure of the inlet and outlet ends in real time to ensure that the mixing process is carried out under a safe and stable pressure. If the pressure rises or falls abnormally, it may mean that there is a blockage, leakage or other problems inside the mixer 13, and timely inspection and maintenance can be carried out to prevent accidents. The outlet end of the high-efficiency pipeline mixer 13 is also provided with an ethanol concentration meter, so as to monitor in real time whether the ethanol concentration after mixing reaches the set value. The outlet of the high-efficiency pipeline mixer 13 is connected to the finished ethanol solution pipeline 96 and the recovery pipeline respectively through a tee, and the recovery pipeline transports the unqualified ethanol solution after mixing to the ethanol recovery room, while the qualified finished ethanol solution pipeline 96 is connected to the import of the finished product storage tank 11, and the finished ethanol solution pipeline is provided with a turbine flowmeter to detect the ethanol flow delivered to the finished product storage tank 11.

Of course, a circulation reflux pipeline 117 is also provided between the outlet of the variable frequency delivery pump 112 and the inlet of the finished product storage tank 11. When the required finished ethanol is prepared, the finished ethanol solution can pass through the delivery pump 112 and the circulation reflux pipeline 117, and the finished ethanol is fully mixed in the finished product storage tank 11, so that the ethanol concentration is more accurate; bimetallic thermometers are provided on the inlet and outlet sides of the shell-and-tube heat exchanger 12 to detect the temperature of the ethanol solution flowing into and out of the shell-and-tube heat exchanger 12; the shell-and-tube heat exchanger 12 is introduced with industrial steam through a steam pipeline 115, and condensed water is discharged through a condensed water pipe provided with a steam trap 114. The ethanol solution discharged from the finished product storage tank 11 can be heated to a set temperature by the shell-and-tube heat exchanger 12 and then transported to a designated location.
