Description

Technical Field

[0001] The present invention relates to the field of pharmaceutical disinfection, and more particularly to a sterilization device for preparing veterinary drugs. Background Art

[0002] In the field of veterinary drug production, many powdered or granular veterinary drugs currently require strict sterilization after preparation. Some pharmaceutical raw materials also require sterilization before processing. This is crucial for protecting veterinary drugs from microbial contamination during production and maintaining sterility during subsequent storage and use. Failure to effectively sterilize veterinary drugs or raw materials during production can result in substandard drug quality and potentially pose safety risks during use, impacting animal health, and even causing economic losses.

[0003] Sterilization tanks are commonly used in existing sterilization devices. For example, a sterilization device for pharmaceutical production disclosed in a Chinese patent (Application No. 202320835595.7) uses an aeration device to blow air through the powder inside the tank, causing it to swirl up and down, ensuring that all parts of the drug are fully exposed to the ultraviolet light. This ensures that the powder is evenly irradiated by the ultraviolet light, improving the sterilization effect. However, in actual application, this aeration method has obvious limitations.

[0004] When aerating medication, those closer to the aeration holes are effectively lifted and tumbled, while those further away struggle to receive sufficient airflow, resulting in incomplete tumbling. This uneven tumbling prevents some medications from receiving sufficient UV light, impacting the overall sterilization effect. Furthermore, if the aeration intensity is improperly controlled, particularly at low levels, medication at the aeration holes may enter the aeration pipes, causing blockage. Once the pipes are clogged, aeration will not function properly, further exacerbating the instability of the sterilization effect. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a sterilization equipment for the preparation of veterinary drugs, which can realize the up and down movement of the drug in the sterilization tank by utilizing the circulation component, and then use ultraviolet sterilization lamp 1 and ultraviolet sterilization lamp 2 to uniformly sterilize the surface of the drug, and at the same time use the high temperature generated by the electric heating wire to sterilize the inside of the drug, thereby achieving multiple sterilization.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figures 1 to 2 A sterilization device for preparing veterinary drugs comprises a sterilization tank 1, a sealing cover 2 is installed at the upper end of the sterilization tank 1, ultraviolet sterilization lamps 5 are evenly distributed on the inner wall of the sterilization tank 1, and an electric heating wire is installed in the side wall of the sterilization tank 1;

[0038] A circulation pipe 6 is installed in the sterilization tank 1. The lower end of the circulation pipe 6 is fixedly connected to a conical cover 9. A gap for the movement of medicine is left between the lower end of the conical cover 9 and the bottom wall of the sterilization tank 1. The outer wall of the circulation pipe 6 is fixedly connected to two evenly distributed ultraviolet sterilization lamps 7. A circulation component is also installed in the sterilization tank 1. The circulation component is used to drive the medicine in the sterilization tank 1 to enter from the lower end of the circulation pipe 6 and flow out from the upper end of the circulation pipe 6. A motor 3 is installed at the upper end of the sealing cover 2. The motor 3 is used to provide driving force for the circulation component. A rotating rod 4 is installed on the output shaft of the motor 3. The lower end of the rotating rod 4 movably passes through the sealing cover 2 and extends to the interior of the sterilization tank 1.

[0039] The circulation component also includes a spiral auger 10, which is arranged in the circulation pipe 6. The lower end of the rotating rod 4 is connected to the spiral auger 10. The lower end of the spiral auger 10 is rotatably connected to the inner bottom of the sterilization tank 1. The inner bottom wall of the sterilization tank 1 is designed in an arc-shaped structure. A support rod 8 is fixedly connected between the circulation pipe 6 and the inner wall of the sterilization tank 1. A frustum plate 11 is fixedly connected to the outer wall of the circulation pipe 6 near the upper end.

[0040] When performing the sterilization operation, first open the sealing cover 2 and put an appropriate amount of powdered granular medicine into the sterilization tank 1, then cover the sealing cover 2 and turn on the ultraviolet germicidal lamp 1 5, the ultraviolet germicidal lamp 2 7 and the heating wire, and at the same time turn on the motor 3. The motor 3 will drive the spiral auger 10 to rotate. The spiral auger 10 will transport the powdered granular medicine from the lower end of the circulation pipe 6 to the upper end during the rotation process. The powdered granular medicine will finally be transported out from the upper end of the circulation pipe 6, and the powdered granular medicine will fall onto the round table plate 11 and roll down along the slope of the round table plate 11. The continuously falling powdered granular medicine forms a A cylindrical powder curtain wall, ultraviolet sterilization lamp 1 5 irradiates the outside of the cylindrical powder curtain wall from the outside, and ultraviolet sterilization lamp 2 7 irradiates the inside of the cylindrical powder curtain wall from the inside, which helps the powdered granular medicine to be evenly irradiated by the ultraviolet lamp and sterilized, thereby improving the sterilization effect. In addition, the turned-on heating wire increases the temperature inside the sterilization tank 1, and the high temperature is used to sterilize the inside of the powdered granular medicine. Because the ultraviolet lamp has a good sterilization effect on the surface of the medicine, the inside is difficult to be affected by light, and the inside of the medicine is sterilized by combining with high-temperature sterilization, thereby improving the overall sterilization effect of the medicine.

[0041] like Figures 1 to 2 As shown, a discharge pipe 14 is installed near the upper end of the outer wall of the sterilization tank 1, and a heat dissipation pipe 15 is installed near the lower end of the outer wall of the sterilization tank 1. The interiors of the discharge pipe 14 and the heat dissipation pipe 15 are interconnected with the interior of the sterilization tank 1, and a breathable cotton 16 is installed on the side wall of the sterilization tank 1 at the connection with the discharge pipe 14.

[0042] When heat dissipation operation is performed after sterilization is completed, the ultraviolet germicidal lamp 1 5, the ultraviolet germicidal lamp 2 7 and the electric heating wire are turned off, and the lid on the discharge pipe 14 and the heat dissipation pipe 15 is opened. Because the heat dissipation pipe 15 is equipped with breathable cotton 16, the powder can be prevented from flowing out from the heat dissipation pipe 15. External cold air can enter the inside of the sterilizing tank 1 through the discharge pipe 14 and the heat dissipation pipe 15, and the powder granular medicine in the tank body is dissipated. If you are worried that the air outside contains bacteria and enters the sterilizing tank 1 through the discharge pipe 14 and the heat dissipation pipe 15 to contaminate the powder granular medicine after sterilization, the sterilizing tank 1 can be placed in a sterile room for operation. Through the continuous rotation of the spiral auger 10, the powder granular medicine continuously falls from the round table plate 11, which helps the powder granular medicine to fully contact the cold air entering and accelerate the heat dissipation speed of the powder granular medicine.

[0043] like Figure 3As shown, a support groove 13 is provided on the inner wall of the sterilization tank 1, a limit portion 12 is provided on the upper end of the frustum plate 11, and a collecting plate 17 is provided on the support groove 13 and the limit portion 12. The collecting plate 17 is designed to be higher in the middle than the edge, and a handle 18 is installed on the upper side slope of the collecting plate 17. The center of the collecting plate 17 is sleeved on the circulation pipe 6, and the lower end of the discharge pipe 14 is close to the edge of the collecting plate 17.

[0044] The public document (a sterilization device for pharmaceutical production, application number: 202320835595.7) is to open the sealing cover 2 of the sterilization tank 1 and then tilt the sterilization tank 1 for pouring. If the position of the collecting tube or the collecting box is not accurate, the medicine will easily spill when the sterilization tank 1 is tilted. Because the bottom center position of the sterilization tank 1 of the present application needs to provide a support point for the installation position of the lower end of the spiral auger 10, it is impossible to open a discharge port at the bottom center position of the sterilization tank 1. If the discharge port is forcibly opened next to the bottom center position of the sterilization tank 1, when the drug discharge operation is performed, since the discharge port deviates from the bottom center position, the drug will be affected by the internal shape of the sterilization tank 1 and the characteristics of the material itself during the discharge process, resulting in drug residues next to the bottom center of the sterilization tank 1. According to the present invention, when it is necessary to take out the powdered granular medicine from the sterilization tank 1, the sealing cover 2 is opened, and then the handle 18 is held, and the center position of the collecting plate 17 is placed on the circulation pipe 6. The limiting part 12 and the bottom wall of the supporting groove 13 support the lower end of the collecting plate 17. Then the sealing cover 2 is covered, the motor 3 is turned on, and the spiral auger 10 rotates to transport the medicine to the collecting plate 17. The medicine flows to the edge along the slope of the collecting plate 17, and the medicine is discharged from the discharge pipe 14. After the medicine at the bottom of the tank body is transported to the collecting plate 17, the sealing cover 2 is opened, and then a brush is used to sweep the medicine at the edge of the collecting plate 17 into the discharge pipe 14 to discharge the medicine.

[0045] like Figures 11 to 12 As shown, the rotating rod 4 is fixedly connected to a polygonal column 28. The upper end surface of the auger 10 is provided with a prism groove 29, into which the polygonal column 28 is inserted. Each time the sealing cover 2 is placed on the sterilization tank 1, the polygonal column 28 is inserted into the prism groove 29. When the motor 3 drives the rotating rod 4 to rotate, the polygonal column 28 drives the auger 10 to rotate. The lower end of the polygonal column 28 has a tapered structure, which facilitates its insertion into the prism groove 29.

[0046] Example 2

[0047] like Figures 4 to 6As shown, the circulation component also includes a fan blade 19, which is fixedly connected to the side wall of the rotating rod 4. An air collecting hood 20 with an open upper end and a sealed lower end is installed on the outside of the fan blade 19. The lower end of the rotating rod 4 moves through the air collecting hood 20. A gap for air flow is left between the upper end of the air collecting hood 20 and the sealing cover 2. The side wall of the air collecting hood 20 is installed with an exhaust hood 21. An air duct 23 is installed at one end of the exhaust hood 21 away from the air collecting hood 20. The end of the air duct 23 away from the exhaust hood 21 contacts the inner wall of the sterilization tank 1. An air duct 24 is installed on the outer wall of the sterilization tank 1. One end of the air duct 24 passes through the side wall of the sterilization tank 1 and is docked with the opening of the air duct 24. A circular tube 25 is fixedly connected to the inner wall of the conical cover 9. A circular opening is provided at the upper end of the circular tube 25. A breathable net 26 is installed at the circular opening of the circular tube 25. The end of the air duct 24 away from the air duct 23 passes through the side wall of the sterilization tank 1 and is connected to the circular tube 25. The air flow in the air collecting hood 20 is introduced into the circular tube 25 through the air duct 24. The upper end of the exhaust hood 21 is fixedly connected to a connecting column 22, and the upper end of the connecting column 22 is fixedly connected to the sealing cover 2.

[0048] During sterilization, the motor 3 is turned on, and the motor 3 drives the fan blades 19 to rotate through the rotating rod 4. The fan blades 19 will transport the air into the wind collecting cover 20 when rotating. The air enters the exhaust cover 21 and is discharged from the air guide pipe 23. Finally, the air enters the annular tube 25 along the air duct 24 and is discharged from the annular opening of the annular tube 25 and blown into the circulation tube 6, so that the air flow in the circulation tube 6 flows out to the upper end. The medicine at the lower end of the circulation tube 6 can be blown to the upper end by the air flow. It is ejected and falls from the upper end of the circulation tube 6. The air flow rate of the lower end opening of the circulation tube 6 is greater than the air flow rate around the lower end of the circulation tube 6. According to the fact that the greater the flow rate, the smaller the air pressure value, it means that the lower end opening of the circulation tube 6 also has a certain suction force, which is convenient for the surrounding convenient medicines to come to the lower end opening and be blown into the circulation tube 6 by the air flow, and finally fall from the upper end opening. They are evenly sterilized by the irradiation of the ultraviolet germicidal lamp 1 5 and the ultraviolet germicidal lamp 2 7, and the high-temperature sterilization operation is carried out in conjunction with the heating of the electric heating wire.

[0049] During heat dissipation, the caps on the discharge pipe 14 and the heat dissipation pipe 15 are opened, and the opening of the discharge pipe 14 is covered with a breathable mesh to prevent the medicine from being sprayed out from the opening of the discharge pipe 14. Cold air enters the sterilization tank 1 through the discharge pipe 14 and the heat dissipation pipe 15. When the medicine circulates up and down, it can fully contact with the cold air, which is convenient for heat dissipation of the medicine.

[0050] When the medicine needs to be discharged, open the sealing cover 2, place the collection plate 17 into the sterilization tank 1, cover the opening of the discharge pipe 14 with a layer of air-permeable mesh, turn on the motor 3, and through the action of the airflow, the medicine is transported to the collection plate 17, then open the sealing cover 2, and use a brush to sweep the medicine into the discharge pipe 14 for discharge.

[0051] like Figures 9 and 10 As shown, a limiting groove 27 is provided on the inner wall of the sterilization tank 1 at the contact position of the air duct 23 , and the limiting groove 27 is used to facilitate the docking of the opening of the air duct 23 and the air induced duct 24 .

[0052] like Figure 10 As shown, the open ends of the air duct 23 and the air duct 24 where they are connected are designed with permanent magnetic materials, and the two are magnetically attracted to each other. A rubber ring is fixedly connected to the opening where the air duct 23 and the air duct 24 are connected. This design can ensure the sealing of the connection between the air duct 23 and the air duct 24, and prevent air from escaping when transporting air.

[0053] Example 3

[0054] Combining Example 1 and Example 2, when performing a sterilization operation, the airflow creates suction at the lower end of the circulation tube 6, facilitating the movement of the drug to the spiral auger 10 and the delivery of the drug by the spiral auger 10. The airflow flowing in the circulation tube 6 also facilitates the upward delivery of the drug by the spiral auger 10.

[0055] During the heat dissipation operation, the opening of the discharge pipe 14 is covered with a breathable mesh, and the airflow in the circulation pipe 6 facilitates the cold air entering the sterilization tank 1 to reduce the temperature inside the sterilization tank 1, thereby reducing the overall temperature. The flow of air also facilitates the cold air to enter the sterilization tank 1. The up and down circulation of the medicine facilitates the contact between the medicine and the air, thereby facilitating the heat dissipation operation of the medicine.

[0056] When discharging the medicine, the collection plate 17 is placed in the sterilization tank 1, the opening of the discharge pipe 14 is covered with a layer of air-permeable mesh, the motor 3 is turned on, and the medicine is transported by the airflow and the spiral auger 10 so that the medicine is transported to the collection plate 17. The suction force at the lower end of the circulation pipe 6 can avoid drug residue at the lower end of the circulation pipe 6. Then, the sealing cover 2 is opened, and a brush is used to sweep the medicine into the discharge pipe 14 for discharge.

[0057] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
