[0002] Animal-derived drugs refer to the process of preparing drugs from animals or their tissues, secretions, metabolites, etc., through extraction, separation, purification, and other processes. These drugs mainly include biological products, hormones, enzyme preparations, and traditional Chinese medicines. Their production process must strictly follow the Good Manufacturing Practice (GMP) standards to ensure safety and efficacy, and they are widely used in the medical, healthcare, and scientific research fields.

[0003] Traditional mixing devices rely solely on gravity for material feeding, which can lead to material accumulating and forming clumps at the outlet, causing interruptions or uneven flow. This necessitates frequent manual cleaning of blockages, affecting production efficiency and potentially causing secondary contamination due to the device being opened during cleaning. To address these issues, a closed mixing device for animal drug production is urgently needed. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that traditional discharge pipes rely solely on gravity for material feeding, which can easily lead to the accumulation and compression of raw materials in the discharge port, resulting in interrupted discharge or uneven flow, requiring frequent manual cleaning of blockages and affecting production efficiency. Therefore, a closed mixing device for animal drug production is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A closed mixing device for animal drug production includes a mixing tank, a first electric push rod fixedly installed on one side of the lower part of the mixing tank, a second electric push rod connected to one side of the upper part of the mixing tank, a main synchronous pulley rotatably connected to the other side of the upper part of the mixing tank via a shaft, a feed pipe connected to the upper part of the mixing tank, a discharge pipe connected to the lower part of the mixing tank, a fixed frame connected to the upper part of the mixing tank, a hollow rod rotatably connected to the inside of the mixing tank via a bearing, one end of the hollow rod passing through the mixing tank and connected to a secondary synchronous pulley, a fixed rod connected to the lower part of the fixed frame, and multiple main bevel gears connected to the fixed rod; The main bevel gear is meshed with secondary bevel gears on both sides. A connecting rod is connected to the secondary bevel gears. Multiple stirring plates are connected to the connecting rod. A sealing cover is connected to the movable end of the second electric push rod. A movable cover is connected below the sealing cover. A filling port is opened on one side of the movable cover. A sliding cylinder is slidably connected to the discharge pipe. A rotating rod is rotatably connected to the discharge pipe through a bearing. Multiple disturbance plates are connected to the rotating rod. Spur gears are connected to both ends of the rotating rod through the discharge pipe.

[0006] As a further description of the above technical solution: A motor is fixedly installed above the mixing tank. The output shaft of the motor is connected to the main synchronous pulley. Toothed synchronous belts are meshed on the main synchronous pulley and the auxiliary synchronous pulley.

[0007] As a further description of the above technical solution: One end of the fixing rod passes through the hollow rod and is fixedly connected to the inner wall of the mixing tank. The fixing rod is rotatably connected to the hollow rod through a bearing. Both the main bevel gear and the secondary bevel gear are located inside the hollow rod.

[0008] As a further description of the above technical solution: The connecting rods are rotatably connected to both sides of the hollow rod via bearings, and the stirring plates on the multiple connecting rods are arranged in an alternating pattern. The mixing tank has a sloping conical design at the bottom and is connected to the discharge pipe at its lowest point. A control valve is installed on the discharge pipe.

[0009] As a further description of the above technical solution: The movable cover slides inside the feed pipe, and a sealing ring is connected to the movable cover, which is in close contact with the inner wall of the feed pipe.

[0010] As a further description of the above technical solution: The slide cylinder has racks connected to both sides inside. The racks and spur gears are both installed inside the slide cylinder and mesh with each other. The movable end of the first electric push rod is connected to the slide cylinder.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by activating the second electric push rod to push and pull the sealing cover, the movable cover slides inside the feed pipe. When the movable cover moves upward out of the feed pipe, the operator can fill the raw material through the filling port. Then, the sealing cover is pulled down to make the movable cover slide into the feed pipe, so that the sealing ring comes into contact with the wall of the feed pipe, thereby sealing and preventing foreign objects from entering. When discharging, by activating the first electric push rod to push the slide cylinder to slide downward on the discharge pipe, the meshing of the rack and spur gear drives the rotating rod to rotate inside the discharge pipe, thereby driving the disturbance plate to rotate, thereby agitating the blocked raw material, ensuring the smoothness of discharge and improving the discharge efficiency.

[0012] 2. In this utility model, by starting the motor to rotate the main synchronous pulley, the main synchronous pulley drives the auxiliary synchronous pulley through the toothed synchronous belt, causing the hollow rod to rotate inside the mixing tank. The rotating hollow rod can synchronously drive the connecting rod and the auxiliary bevel gear, causing the auxiliary bevel gear to rotate around the fixed rod and the main bevel gear. Then, by utilizing the meshing of the main bevel gear and the auxiliary bevel gear, the connecting rod drives the stirring plate to rotate, thereby realizing the compound motion of the stirring plate and improving the mixing effect and efficiency of the raw materials.

[0015] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0016] In its specific implementation, such as Figures 1-4 This utility model provides a technical solution: a closed mixing device for animal drug production, including a mixing tank 1, a first electric push rod 2 fixedly installed on one side of the lower part of the mixing tank 1, a second electric push rod 3 connected to one side of the upper part of the mixing tank 1, a main synchronous pulley 4 rotatably connected to the other side of the upper part of the mixing tank 1 via a shaft, a motor 22 fixedly installed on the upper part of the mixing tank 1, the output shaft of the motor 22 connected to the main synchronous pulley 4, and a toothed synchronous belt 23 meshing on the main synchronous pulley 4 and the auxiliary synchronous pulley 9. Through the cooperation of the main synchronous pulley 4, the auxiliary synchronous pulley 9 and the toothed synchronous belt 23, the hollow rod 8 can drive the stirring plate 14 to rotate around the fixed rod 10, thereby causing the stirring plate 14 to stir the raw materials to achieve mixing.

[0017] A feed pipe 5 is connected to the top of the mixing tank 1, and a discharge pipe 6 is connected to the bottom of the mixing tank 1. A fixed frame 7 is connected to the top of the mixing tank 1. A hollow rod 8 is rotatably connected inside the mixing tank 1 via a bearing. One end of the hollow rod 8 passes through the mixing tank 1 and is connected to a secondary synchronous wheel 9. A fixed rod 10 is connected below the fixed frame 7. Multiple main bevel gears 11 are connected to the fixed rod 10. Secondary bevel gears 12 are meshed on both sides of the main bevel gears 11. One end of the fixed rod 10 passes through the hollow rod 8 and is fixedly connected to the inner wall of the mixing tank 1. The fixed rod 10 is rotatably connected to the hollow rod 8 via a bearing. The main bevel gears 11 and secondary bevel gears 12 are both located inside the hollow rod 8. The hollow rod 8 isolates and protects the main bevel gears 11 and secondary bevel gears 12, preventing the raw materials from directly contacting the main bevel gears 11 and secondary bevel gears 12. By utilizing the meshing of the main bevel gears 11 and secondary bevel gears 12, the stirring plate 14 can rotate around the fixed rod 10 and rotate around the connecting rod 13 as the axis, thereby achieving compound motion and improving the mixing effect.

[0018] A connecting rod 13 is connected to the secondary bevel gear 12, and multiple stirring plates 14 are connected to the connecting rod 13. The connecting rod 13 is rotatably connected to both sides of the hollow rod 8 through bearings, and the stirring plates 14 on the multiple connecting rods 13 are arranged in an alternating manner. The bottom of the mixing tank 1 is designed with a sloping cone shape, and the lowest point is connected to the discharge pipe 6. A control valve is installed on the discharge pipe 6. The multiple alternating stirring plates 14 can improve the mixing effect when rotating, and the sloping cone shape at the bottom of the mixing tank 1 can guide the raw materials to gather towards the discharge pipe 6, thereby facilitating discharge.

[0019] The movable end of the second electric push rod 3 is connected to a sealing cover 15, and a movable cover 16 is connected below the sealing cover 15. A filling port 17 is opened on one side of the movable cover 16. The movable cover 16 slides inside the feed pipe 5. A sealing ring 24 is connected to the movable cover 16. The sealing ring 24 is in close contact with the inner wall of the feed pipe 5. Through the close contact between the sealing ring 24 and the inner wall of the feed pipe 5, the sealing can be completed when the movable cover 16 enters the feed pipe 5.

[0020] A slide cylinder 18 is slidably connected to the discharge pipe 6. A rotating rod 19 is rotatably connected inside the discharge pipe 6 via a bearing. Multiple disturbance plates 20 are connected to the rotating rod 19. Both ends of the rotating rod 19 pass through the discharge pipe 6 and are connected to spur gears 21. Racks 25 are connected to both sides inside the slide cylinder 18. Both racks 25 and spur gears 21 are set inside the slide cylinder 18 and mesh with each other. The movable end of the first electric push rod 2 is connected to the slide cylinder 18. The slide cylinder 18 can protect the racks 25 and spur gears 21, reducing the adhesion and collision of impurities. The slide cylinder 18 slides on the discharge pipe 6, so that the discharge pipe 6 can assist in guiding the movement of the slide cylinder 18 and prevent it from tilting during movement.

[0021] Working principle: The second electric push rod 3 is activated to push the sealing cover 15 upwards, causing the movable cover 16 to slide inside the feed pipe 5. When the movable cover 16 moves upwards out of the feed pipe 5, the operator can fill the raw material through the filling port 17. Then, the sealing cover 15 is pulled down to make the movable cover 16 slide into the feed pipe 5, causing the sealing ring 24 to come into contact with the wall of the feed pipe 5, thereby sealing the pipe. Then, the main synchronous pulley 4 is rotated by the starting motor 22, causing the main synchronous pulley 4 to drive the auxiliary synchronous pulley 9 using the toothed synchronous belt 23, so that the hollow rod 8 moves in the mixing tank 1. The inner fixed rod 10 rotates, and during the process, the meshing of the main bevel gear 11 and the secondary bevel gear 12 enables the connecting rod 13 to drive the stirring plate 14 to rotate, thereby realizing the compound motion of the stirring plate 14 to improve the mixing effect of the raw materials. When discharging, the first electric push rod 2 is activated to push the slide cylinder 18 to slide downward on the discharge pipe 6. The meshing of the rack 25 and the spur gear 21 drives the rotating rod 19 to rotate in the discharge pipe 6, which in turn drives the disturbance plate 20 to rotate, thereby stirring the blocked raw materials and ensuring smooth discharge.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
