Description

Technical Field

[0001] This utility model relates to the field of sterilization tank technology, specifically a sterilization mechanism for liquid preparations. Background Technology

[0002] Liquid formulations refer to liquid dispersion systems prepared by dispersing drugs in a specific form in a liquid medium for oral or topical use. Liquid formulations undergo sterilization during reprocessing, and sterilization tanks are a common technique for sterilizing liquid formulations. Sterilization tanks are a commonly used sterilization device suitable for the sterilization of liquid formulations.

[0003] Sterilization is a crucial step in the preparation of liquid formulations to ensure the sterility and safety of the product. Existing sterilization tanks have heating elements located on the outside of the tank, making disassembly inconvenient. These heating elements, often consisting of heating resistors or heating rods, are prone to damage after prolonged operation. The lack of easy removal of these external heating elements also makes maintenance and replacement cumbersome. Therefore, we propose a sterilization mechanism for liquid formulations.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 4 This utility model provides a technical solution: a sterilization mechanism for liquid preparations, including an outer shell 1 and a tank 4. The bottom of the outer shell 1 is provided with multiple support legs 11, and four support legs 11 are sufficient to make it stand stably on the ground.

[0022] like Figure 1 and Figure 2 As shown, the tank body 4 is coaxially placed inside the outer shell 1, and the top of the tank body 4 is located outside the top of the outer shell 1. In order to make the tank body 4 more stable, mounting skirts 3 are provided on the top of the tank body 4 and the top of the outer shell 1. The mounting skirts 3 are detachably connected to each other, specifically by fixing the upper and lower mounting skirts 3 with bolts.

[0023] Next, multiple first openings 15 are provided on the side of the outer shell 1, and an insulated inner liner 14 is provided inside the outer shell 1. The insulated inner liner 14 is provided with a second opening 16 at the position corresponding to the first openings 15, and there is a step between the first openings 15 and the second openings 16.

[0024] like Figure 1 As shown, each of the first openings 15 is sealed by a detachable enclosure 10. Specifically, the edge of the enclosure 10 is fastened to the edge of the first opening 15 by bolts, which facilitates disassembly and installation. A heating element 18 is provided on the inner surface of the enclosure 10. The heating element 18 is a bent heating resistance wire or heating rod. Several heating elements 18 are located around the tank 4 and are used to heat the tank 4. The heating elements are specifically installed as follows: an insulation plate 17 is provided on the inner surface of the enclosure 10, and the heating elements 18 are disposed on the surface of the insulation plate 17.

[0025] Specifically, the insulation board 17 and the insulation liner 14 are made of materials such as furnace plate, ceramic insulation layer, and heat insulation cotton. Their function is to seal the heat generated by the heating element 18, preventing heat loss and allowing the heat generated by the heating element 18 to heat the tank for sterilization. During installation, when the surrounding plate 10 is placed at the first opening 15, the edge of the insulation board 17 is positioned within the step. This not only allows for the positioning and installation of the insulation board 17, but also, because there is a gap between the insulation board 17 and the tank 4 caused by the thickness of the insulation liner 14, and between the heating element 18 and the tank 4, direct contact between the heating element 18 and the tank 4 is avoided.

[0026] Specifically, this application places the heating element on the enclosure 10. When the enclosure 10 is removed, the heating element 18 can be exposed, allowing for inspection and replacement of the heating element 18. The operation is simple and convenient.

[0027] Furthermore, the top of the tank body 4 is detachably equipped with a sealing cover 5. The edge of the sealing cover 5 is fastened to the top of the tank body 4 by bolts. The top of the sealing cover 5 is equipped with an observation port 20, which is sealed by a detachable cover. The observation port 20 can not only be used to add materials into the tank body 4, but also to observe the internal condition of the tank body after opening the observation port 20.

[0028] The top of the sealing cap 5 is also provided with two mounting ports 8 and at least one feed port 6. The two mounting ports 8 are used to install a level gauge and a temperature detection probe, respectively. The detection ends of the level gauge and the temperature detection probe are placed in the formulation, and are used to detect the liquid level and temperature, respectively. Figure 1 As shown, a drive device 7 is coaxially mounted on the top of the sealing cover 5. The drive device 7 is a motor. A stirring shaft 2 is coaxially mounted on the rotating shaft of the drive device 7. The stirring shaft 2 is placed inside the tank body 4 and has stirring blades. In actual use, at least one stirring blade is positioned above the liquid level so that the foam generated by the preparation during high-temperature sterilization can be stirred and defoamed.

[0029] It should be noted that there are more than two installation ports 8; the remaining installation ports 8 can be used to install various detection and sensing instruments, such as pH detectors, pressure detectors, etc. Furthermore, the installation ports 8 should be located at the inner edge of the tank body 4, so that when an object is installed inside the installation port, it will not come into contact with the stirring blades.

[0030] Based on the above embodiments, this application also includes a control cabinet 13, which contains a controller connected to the heating element 18, the drive device 7, a level gauge, and a temperature detection probe. Figure 1 and Figure 2 As shown, a display screen, operation buttons and an alarm are also provided on the surface of the control cabinet 13.

[0031] Furthermore, in summary, when the can uses the high temperature generated by the heating element 18 for sterilization, the preparation needs to be discharged after the preset sterilization time, such as... Figure 3 and Figure 4 As shown, a discharge valve 19 is provided at the bottom of the tank body 4, and the discharge valve 19 is located outside the outer shell 1.

[0032] Based on the above embodiments, further optimization is possible, and a pressure balancing valve 9 is also provided on the top of the sealing cover.

[0033] Based on the above embodiments, further optimization can be achieved by mounting the control cabinet 13 on the mounting bracket 12, and then fixing the mounting bracket 12 between the support legs.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
