[0022] Please see Figure 1-4This utility model provides an embodiment of a vacuum device for traditional Chinese medicine manufacturing, comprising an evaporation assembly 1. One side of the evaporation assembly 1 is connected to a vacuum assembly 3, and the evaporation assembly 1 and the vacuum assembly 3 are controlled by a PLC controller 5. The PLC controller 5 communicates with a touch screen 4 via a wire 6. The vacuum assembly 3 includes a vacuum pump 32, which has an inlet 38 and an outlet 39. The outlet 39 is connected to a liquid storage tank 30 via a first pipeline 35. The evaporation assembly 1 includes a vacuum tank 13 and a condensation tower 10 installed on the vacuum tank 13. The condensation tower 10 is also provided with a second pipeline 15. The second pipeline 15 is connected to the inlet 38 via a check valve 33. The vacuum tank 13 is also provided with a level gauge 11 and a first pressure gauge 12 that communicate with the PLC controller 5. Since the evaporation assembly 1 and the vacuum assembly 3 are controlled by the PLC controller 5, the information of the evaporation assembly 1 and the vacuum assembly 3 is displayed on the touch screen 4 through the PLC controller 5. The user sets the vacuum pressure through the touch screen 4 and transmits it to the PLC controller 5. The PLC controller 5 automatically starts the vacuum pump 32 according to the set pressure. When there is no external vacuum requirement, the system automatically stops the vacuum pump 32 to save energy, reduce labor, and improve equipment production efficiency for the user.

[0023] Based on the above scheme, the cooling component 2 includes a heat exchanger 20. The cold side outlet of the heat exchanger 20 is connected to the coolant inlet 34 of the vacuum pump 32 through a third pipeline 27. Therefore, the heat exchanger 20 can be used to cool the water source, so that the impeller chamber of the vacuum pump 32 can work normally without the temperature becoming too high, thereby protecting the vacuum pump 32 and extending its service life.

[0024] Furthermore, since the cold side inlet of the heat exchanger 20 is connected to the first pump body 28, and the liquid inlet of the first pump body 28 is connected to the water outlet 31 on the storage tank 30 through the fourth pipeline 210, the first pump body 28 can be used to make the water flow to the impeller cavity of the vacuum pump 32 after passing through the heat exchanger 20, so as to provide a continuous source of low-temperature water to the impeller cavity of the vacuum pump 32, thereby alleviating the problem of the impeller cavity water temperature rising too quickly.

[0025] Meanwhile, since the storage tank 30 is also provided with a replenishment port 37, purified water from the outside can be introduced into the storage tank 30 through the replenishment port 37. Then, the purified water is circulated through the first pump body 28 to the impeller chamber of the vacuum pump 32. Through the circulation of purified water, the problem of damage to the vacuum pump 32 due to excessive temperature can be avoided. In addition, since the storage tank 30 is also provided with an exhaust port 36, the air source from the vacuum pump 32 can be discharged, so as to keep the air pressure inside the storage tank 30 balanced.

[0026] Furthermore, since the third pipeline 27 is also equipped with a second pressure gauge 25 and a temperature sensor 26 that communicate with the PLC controller 5, the water pressure inside the third pipeline 27 can be obtained through the second pressure gauge 25, and the water temperature inside the third pipeline 27 can be obtained through the temperature sensor 26. This information is then sent to the PLC controller 5, allowing the real-time data to be displayed to the user via the touchscreen 4. The threshold values ​​for the second pressure gauge 25 and the temperature sensor 26 can also be set via the touchscreen 4. When the threshold value is exceeded, the PLC controller 5 reduces the rotation speed of the first pump body 28 to slow down the flow rate of purified water, thus preventing damage to the vacuum pump 32 caused by high-temperature, high-pressure purified water. When the threshold value is not reached, the PLC controller 5 increases the rotation speed of the first pump body 28 to increase the flow rate of purified water, thereby reducing the temperature of the vacuum pump 32. Based on this, the pressure gauge and temperature sensor settings facilitate the PLC controller 5's real-time monitoring and control of the water temperature and pressure inside the third pipeline 27.

[0027] For ease of maintenance, a branch line 29 is provided on the third pipeline 27, and the branch line 29 is connected to the coolant inlet 34 through a butterfly valve 211. Therefore, when one of the vacuum pumps 32 is damaged, the branch line 29 can be closed through the butterfly valve 211 to facilitate the disassembly, replacement and maintenance of the vacuum pump 32.

[0028] In particular, the number of branch lines 29 is equal to the number of vacuum pumps 32, and there are multiple branch lines 29. Therefore, the device can be equipped with multiple vacuum pumps 32, and each vacuum pump 32 can operate independently under the action of the butterfly valve 211. Based on this, multiple vacuum pumps 32 can be used simultaneously to evacuate the vacuum tank 13 to improve the vacuum level inside the vacuum tank 13. At the same time, the butterfly valve 211 on the branch line 29 can be closed, thus enabling the repair and maintenance of damaged vacuum pumps 32 without stopping the entire system. In addition, the number of vacuum pumps 32 can be freely increased or decreased through the arrangement of the branch lines 29.

[0029] In order to ensure that the purified water can reliably remove the heat from the vacuum pump 32, the hot side outlet of the heat exchanger 20 is connected to the compressor 24 through the fifth pipeline 213, and the compressor 24 is connected to the hot side inlet of the heat exchanger 20 through the sixth pipeline 214.

[0030] Furthermore, the sixth pipeline 214 is also equipped with a radiator 23 and a second pump body 21, and the coolant in the radiator 23 is transported to the heat exchanger 20 through the second pump body 21. An electronic expansion valve 212 is installed on the sixth pipeline 214 between the second pump body 21 and the heat exchanger 20, and a fan 22 is also provided on one side of the radiator 23.

[0031] In summary, firstly, the refrigerant can circulate between the heat exchanger 20 and the compressor 24, facilitating heat exchange between the refrigerant and purified water within the heat exchanger 20; secondly, the rotational speed of the second pump body 21 can be controlled by the PLC controller 5 to increase the refrigerant flow rate, thereby regulating the temperature of the purified water. For example, when the impeller chamber temperature of the vacuum pump 32 rises, the rotational speed of the second pump body 21 increases, increasing the refrigerant flow rate and thus cooling the purified water. Conversely, when the purified water temperature is low, the rotational speed of the second pump body 21 can be reduced or the second pump body 21 can be shut down, achieving energy saving and consumption reduction of the equipment.

[0032] In addition, since a third pump body 14 is provided at the bottom of the vacuum tank 13, and the condensate in the vacuum tank 13 is extracted through the third pump body 14, the condensate in the vacuum tank 13 can be discharged in a timely manner through the third pump body 14.

[0033] In summary, when the vacuum level is input into the input options on the touchscreen 4, the touchscreen 4 transmits the digital signal to the PLC controller 5. The PLC controller 5 compares the collected data with the first pressure gauge 12 of the vacuum tank 13 to control the number of vacuum pumps 32 that are started and stopped, and records the start time of each vacuum pump 32. When starting, the running time of each vacuum pump 32 is compared, and the pump with the shorter running time is started first. When stopping, the pump with the longer running time is stopped first. The level gauge 11 on the vacuum tank 13 feeds back the level signal to the PLC controller 5, and the PLC controller 5 starts and stops the third pump 14 according to the high or low level.

[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
