Description

Technical Field

[0001] This utility model belongs to the field of sterilization equipment technology, specifically relating to a sterilization equipment for the production of Chinese herbal medicine injections. Background Technology

[0002] As an important dosage form in the modernization of traditional Chinese medicine, the production process of Chinese herbal injections requires extremely stringent aseptic conditions. The sterilization process directly determines product quality and medication safety, making it a core step in the production process. Currently, the sterilization equipment commonly used in the production of Chinese herbal injections mostly uses heated sterilization tanks as the core carrier, achieving high-temperature sterilization of the liquid inside the tank through external heating components.

[0003] Existing equipment typically relies on natural cooling to lower the temperature of the medicinal liquid inside the tank after high-temperature sterilization. Since most heating sterilization tanks are enclosed metal structures, heat is concentrated and has a single dissipation path, natural cooling can take several hours or even longer, significantly extending the production cycle. To reduce the cooling time required for the medicinal liquid, we propose a sterilization device for the production of traditional Chinese medicine injections. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a sterilization device for the production of Chinese herbal medicine injections, which can more efficiently remove the heat inside the heating sterilization tank and rapidly cool the medicinal liquid inside the heating sterilization tank.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sterilization device for the production of traditional Chinese medicine injection, comprising a heating sterilization tank, a drain pipe connected to the bottom of the heating sterilization tank, a drain valve connected to the end of the drain pipe, a filling pipe connected to the top of the heating sterilization tank, a temperature sensor connected to the top of the heating sterilization tank, an outer sleeve connected to the outer side of the heating sterilization tank via a connecting rod, and an internal ventilation duct running vertically through the middle of the heating sterilization tank. The heat sterilization tank is provided with a heating jacket on the outside. A fan position adjustment mechanism is installed on the top outer side of the outer jacket. A mounting bracket is slidably installed on the fan position adjustment mechanism. An exhaust hole is provided through the top and bottom of the mounting bracket. A cooling fan is installed inside the exhaust hole. An outer heat jacket is provided on the outside of the heat sterilization tank. A first heat-conducting fin is provided on the outer side of the outer heat jacket. An inner heat-conducting sleeve is provided on the inner side of the inner ventilation duct. A second heat-conducting fin is provided on the inner side of the inner heat-conducting sleeve. An expansion port is provided at the bottom of the outer jacket.

[0006] The beneficial effects of this invention are as follows: This device sterilizes the liquid medicine inside the heating sterilization tank at high temperature. After sterilization, the control device can control the drive motor to rotate the lead screw. Through the transmission between the lead screw and the mounting frame, the mounting frame moves along the guide rail, moving to the top of the outer sleeve and sealing the top of the outer sleeve. Then, the cooling fan is turned on, drawing air upwards from the bottom of the outer sleeve. Through the expansion port, a large amount of surrounding airflow enters the interior of the outer sleeve and flows upwards along the channel between the outer sleeve and the heating sterilization tank. At the same time, some airflow enters the inner ventilation duct and flows upwards along the interior of the inner ventilation duct. The heat of the liquid medicine inside the heating sterilization tank is conducted to the surface of the heating sterilization tank and to the outer side of the heating sterilization tank. The heat is transferred to the outer heat jacket and the inner heat-conducting jacket located inside the inner ventilation duct, and then to the first and second heat-conducting plates respectively. The airflow between the heating sterilizer and the outer sleeve comes into contact with the outer heat jacket and the first heat-conducting plate, and the airflow inside the inner ventilation duct comes into contact with the inner heat-conducting jacket and the second heat-conducting plate. This effectively removes heat. At the same time, because the flow area in the middle section of the inner side of the outer sleeve is narrowed due to the presence of the heating sterilizer, the flow velocity will be greatly increased when the airflow passes between the outer sleeve and the heating sterilizer and enters the inner ventilation duct under the Venturi effect. This increases the convective heat transfer coefficient and can more efficiently remove the heat inside the heating sterilizer, thus rapidly cooling the liquid medicine inside the heating sterilizer.

[0007] As a further improvement to the above technical solution: the bottom of the heating sterilization tank is provided with feet.

[0008] The feet are used to support this device.

[0009] As a further improvement to the above technical solution: a sealing cap is connected to the top of the filling tube.

[0010] The sealing cap is used to seal the filling tube.

[0011] To avoid excessive pressure inside the sterilization tank during the heating process:

[0012] As a further improvement to the above technical solution: a pressure relief valve is connected to the top of the heating sterilization tank.

[0013] Pressure relief valves are used to release internal pressure in the heat sterilization tank during heat sterilization.

[0014] For the displacement control of the cooling fan:

[0015] As a further improvement to the above technical solution: the fan position adjustment mechanism includes a guide rail installed on the outer side of the top of the outer sleeve, a lead screw rotatably installed on the inner side of the guide rail, a drive motor installed at one end of the guide rail, the output end of the drive motor being connected to the lead screw, and a mounting bracket slidably provided on the inner side of the guide rail.

[0016] The drive motor drives the lead screw to rotate, and through the transmission between the lead screw and the mounting bracket, the mounting bracket moves along the guide rail, so that the mounting bracket moves to the top of the outer sleeve or moves away from the top of the outer sleeve.

[0017] For the control of this device:

[0018] As a further improvement to the above technical solution: a control device is connected to the outer side of the outer sleeve via a support arm. The front of the control device is equipped with a touch screen display, and the inside of the control device is equipped with a programmable PLC controller. The control device is electrically connected to a temperature sensor, a heating sleeve, a drive motor, and a cooling fan.

[0019] The touch screen is used to display the operating interface and to operate the device. The operation of the device can be controlled by the control device.

[0020] To serve as a reminder:

[0021] As a further improvement to the above technical solution: an indicator light is connected to the outer side of the outer sleeve via a support arm, and the indicator light is electrically connected to the control device.

[0022] Once the temperature of the heating sterilization tank reaches the set cooling temperature, the control device automatically activates the indicator light to serve as a reminder.

[0023] In summary, the beneficial effects of this case are as follows:

[0024] 1. This device sterilizes the liquid medicine inside the heating sterilization tank at high temperature. After sterilization, the control device controls the drive motor to rotate the lead screw. Through the transmission between the lead screw and the mounting frame, the mounting frame moves along the guide rail, moving to the top of the outer sleeve and sealing the top of the outer sleeve. Then, the cooling fan is turned on, drawing air upwards from the bottom of the outer sleeve. Through the expansion port, a large amount of surrounding airflow enters the interior of the outer sleeve and flows upwards along the channel between the outer sleeve and the heating sterilization tank. Simultaneously, some airflow enters the inner ventilation duct and flows upwards along its interior. The heat from the liquid medicine inside the heating sterilization tank is conducted to the surface of the tank and then to the outer heat jacket located on the outside of the tank. The heat is transferred to the inner heat-conducting sleeve located inside the inner ventilation duct, and then to the first and second heat-conducting plates through the outer heat-conducting sleeve and the inner heat-conducting sleeve respectively. The airflow between the heating sterilizer and the outer sleeve comes into contact with the outer heat-conducting sleeve and the first heat-conducting plate, and the airflow inside the inner ventilation duct comes into contact with the inner heat-conducting sleeve and the second heat-conducting plate. This effectively removes heat. At the same time, because the flow area in the middle section of the inner side of the outer sleeve is narrowed due to the presence of the heating sterilizer, the flow velocity will be greatly increased when the airflow passes between the outer sleeve and the heating sterilizer and enters the inner ventilation duct under the Venturi effect. This increases the convective heat transfer coefficient and can more efficiently remove the heat inside the heating sterilizer, thus rapidly cooling the liquid medicine inside the heating sterilizer.

[0025] 2. When the temperature of the heating sterilization tank reaches the set cooling temperature, the control device will automatically turn on the indicator light, automatically shut off the cooling fan, and control the drive motor to reverse the drive screw to move the mounting bracket away from the top of the outer sleeve, which serves as a reminder to the staff so that they can come in time to drain the cooled medicine.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0035] like Figure 1-6 As shown, a sterilization device for producing traditional Chinese medicine injection includes a heating sterilization tank 1. A drain pipe 3 is connected to the bottom of the heating sterilization tank 1, and a drain valve 23 is connected to the end of the drain pipe 3. A filling pipe 4 is connected to the top of the heating sterilization tank 1, and a temperature sensor 7 is connected to the top of the heating sterilization tank 1. An outer sleeve 8 is connected to the outside of the heating sterilization tank 1 via a connecting rod. An internal ventilation duct 9 runs vertically through the middle of the heating sterilization tank 1, and a heating sleeve 10 is provided on the outside of the heating sterilization tank 1. A fan position adjustment mechanism is installed on the top outer side of the outer sleeve 8. A mounting bracket 14 is slidably installed on the fan position adjustment mechanism. An exhaust hole 15 is provided between the top and bottom of the mounting bracket 14. A cooling fan 16 is installed on the inner side of the exhaust hole 15. An outer heat jacket 17 is fitted on the outer side of the heating sterilization tank 1. A first heat-conducting plate 18 is provided on the outer side of the outer heat jacket 17. An inner heat-conducting sleeve 19 is provided on the inner side of the inner ventilation duct 9. A second heat-conducting plate 20 is provided on the inner side of the inner heat-conducting sleeve 19. An expansion port 22 is provided at the bottom of the outer sleeve 8.

[0036] This device sterilizes the liquid medicine inside the heating sterilization tank 1 at high temperature. After sterilization, the control device 21 controls the drive motor 13 to drive the lead screw 12 to rotate. Through the transmission between the lead screw 12 and the mounting frame 14, the mounting frame 14 moves along the guide rail 11, moving to the top of the outer sleeve 8 and sealing the top of the outer sleeve 8. Then, the cooling fan 16 is turned on, drawing air upward from the bottom of the outer sleeve 8. Through the expansion port 22, a large amount of surrounding airflow enters the interior of the outer sleeve 8 and flows upward along the channel between the outer sleeve 8 and the heating sterilization tank 1. At the same time, some airflow enters the inner ventilation duct 9 and flows upward along the interior of the inner ventilation duct 9. The heat of the liquid medicine inside the heating sterilization tank 1 is conducted to the surface of the heating sterilization tank 1 and to the outer jacket located on the outside of the heating sterilization tank 1. The heat is conducted to the outer heat jacket 17 and the inner heat-conducting jacket 19 located inside the inner ventilation duct 9, and then to the first heat-conducting plate 18 and the second heat-conducting plate 20 through the outer heat jacket 17 and the inner heat-conducting jacket 19, respectively. The heat can be effectively carried away by the airflow flowing between the heating sterilizer 1 and the outer sleeve 8 and the contact between the outer heat jacket 17 and the first heat-conducting plate 18, as well as the contact between the airflow inside the inner ventilation duct 9 and the inner heat-conducting jacket 19 and the second heat-conducting plate 20. At the same time, since the flow area in the middle section of the inner side of the outer sleeve 8 is narrowed due to the presence of the heating sterilizer 1, the flow velocity will be greatly accelerated under the action of Venturi effect when the airflow flows between the outer sleeve 8 and the heating sterilizer 1 and enters the inner ventilation duct 9, thereby increasing the convective heat transfer coefficient and more efficiently carrying away the heat inside the heating sterilizer 1, thus rapidly cooling the medicine liquid inside the heating sterilizer 1.

[0037] The bottom of the heating sterilization tank 1 is provided with feet 2.

[0038] Foot 2 is used to support this device.

[0039] The top of the filling tube 4 is connected to a sealing cap 5.

[0040] The sealing cap 5 is used to seal the filling tube 4.

[0041] The top of the heating sterilization tank 1 is connected to a pressure relief valve 6.

[0042] The pressure relief valve 6 is used to release the internal pressure of the heating sterilization tank 1 during heating sterilization.

[0043] The fan position adjustment mechanism includes a guide rail 11 installed on the outer side of the top of the outer sleeve 8, a lead screw 12 rotatably installed on the inner side of the guide rail 11, a drive motor 13 installed at one end of the guide rail 11, the output end of the drive motor 13 being connected to the lead screw 12, and a mounting bracket 14 slidably provided on the inner side of the guide rail 11.

[0044] The drive motor 13 drives the lead screw 12 to rotate, and through the transmission between the lead screw 12 and the mounting bracket 14, the mounting bracket 14 moves along the guide rail 11, so that the mounting bracket 14 moves to the top of the outer sleeve 8 or moves away from the top of the outer sleeve 8.

[0045] The outer sleeve 8 is connected to a control device 21 via a support arm. The front of the control device 21 is equipped with a touch screen display. The control device 21 is equipped with a programmable PLC controller. The control device 21 is electrically connected to the temperature sensor 7, the heating sleeve 10, the drive motor 13, and the cooling fan 16.

[0046] The touch screen is used to display the operating interface and to operate the device. The operation of the device can be controlled by the control device 21.

[0047] An indicator light 24 is connected to the outer side of the outer sleeve 8 via a support arm, and the indicator light 24 is electrically connected to the control device 21.

[0048] When the temperature of the heating sterilizer 1 reaches the set cooling temperature, the control device 21 automatically controls the indicator light 24 to light up, serving as a reminder.

[0049] The working principle and usage process of this utility model are as follows: When using this device, the medicine to be sterilized is injected into the heating sterilization tank 1 through the injection pipe 4. After that, the sealing cap 5 is closed to maintain the seal of the heating sterilization tank 1. Then, the heating jacket 10 can be controlled by the control device 21 to electrically heat the medicine inside the heating sterilization tank 1. The medicine inside the heating sterilization tank 1 is sterilized by high temperature. After sterilization is completed, the drive motor 13 can be controlled by the control device 21 to drive the lead screw 12 to rotate. Through the transmission between the lead screw 12 and the mounting frame 14, the mounting frame 14 is moved along the guide rail 11, so that the mounting frame 14 is moved to the top of the outer sleeve 8. The top of the outer sleeve 8 is sealed, and then the cooling fan 16 is turned on. Airflow is drawn upward from the bottom of the outer sleeve 8 through the cooling fan 16. Through the expansion port 22, a large amount of surrounding airflow enters the interior of the outer sleeve 8 and flows upward along the channel between the outer sleeve 8 and the heating sterilizer 1. At the same time, some airflow enters the inner ventilation duct 9 and flows upward along the interior of the inner ventilation duct 9. The heat of the liquid inside the heating sterilizer 1 is conducted to the surface of the heating sterilizer 1, and then to the outer heat jacket 17 located on the outside of the heating sterilizer 1 and the inner heat-conducting jacket 19 located inside the inner ventilation duct 9. Heat is conducted to the first heat-conducting plate 18 and the second heat-conducting plate 20 respectively. Through the contact between the airflow flowing between the heating sterilizer 1 and the outer sleeve 8 and the outer heat-conducting sleeve 17 and the first heat-conducting plate 18, and through the contact between the airflow inside the inner ventilation duct 9 and the inner heat-conducting sleeve 19 and the second heat-conducting plate 20, heat can be effectively carried away. Simultaneously, because the flow area in the middle section of the inner side of the outer sleeve 8 is narrowed due to the presence of the heating sterilizer 1, under the Venturi effect, the airflow velocity is greatly increased after passing between the outer sleeve 8 and the heating sterilizer 1 and entering the inner ventilation duct 9, thus improving the convective heat transfer coefficient and enabling more efficient heat removal. The heat inside the sterilization tank 1 rapidly cools the liquid medicine inside. At the same time, the airflow that has absorbed the heat flows upward rapidly and is blown upward by the cooling fan 16. The temperature of the sterilization tank 1 can be monitored in real time by the temperature sensor 7 and the data is transmitted to the control device 21 in real time. When the temperature of the sterilization tank 1 reaches the set cooling temperature, the control device 21 automatically controls the indicator light 24 to light up and automatically shuts off the cooling fan 16. It also controls the drive motor 13 to drive the lead screw 12 to reverse and move the mounting bracket 14 away from the outer sleeve 8. The operator can then open the drain valve 23 to drain the liquid medicine from the sterilization tank 1.
