Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical powder mixing technology, specifically to a pharmaceutical powder spiral stirring and mixing device. Background Technology

[0002] In the pharmaceutical production process, it is necessary to mix various powdered drugs. Mixing drugs requires the use of mixing equipment to stir and mix them. Existing mixing equipment mostly mixes drugs by simply stirring. This mixing method is prone to uneven mixing and long mixing time.

[0003] Chinese patent CN222427826U discloses a spiral stirring and mixing device. It connects a motor to a rotating shaft via a connecting sleeve, allowing workers to easily install and remove the cover without affecting the mixing of pharmaceutical powders by the rotating shaft. During use, the rotating shaft can premix various pharmaceutical powders through the stirring rod and support rod, and can also drive the spiral blades to stir and mix the mixed pharmaceutical powders and water, achieving different levels of mixing effect for pharmaceutical powders in different states.

[0004] In the above scheme, the mixing of various drug powders is achieved by stirring shaft and support rod. However, the stirring shaft and support rod in a fixed state mainly act on the lateral mixing of drug powders during the rotation and stirring process, while the drug powders in the upper and lower layers are difficult to mix thoroughly. This results in unsatisfactory mixing effect and efficiency when mixing multiple drug powders.

[0005] Therefore, this utility model provides a spiral stirring and mixing device for pharmaceutical powder to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a spiral stirring and mixing device for pharmaceutical powders, which solves the problem that the upper and lower layers of pharmaceutical powders are difficult to mix thoroughly, resulting in unsatisfactory mixing effect and efficiency when mixing multiple pharmaceutical powders.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pharmaceutical powder spiral mixing device includes a mixing tank. A feed pipe and a second motor are respectively installed at both ends of the mixing tank, with the feed pipe connected to the mixing tank. A drive shaft is installed on the output shaft of the second motor, and a first auger and two second augers are installed on the drive shaft. A sleeve is provided inside the mixing tank, and a reinforcing rod is fixedly connected to the sleeve, with one end of the reinforcing rod fixedly connected to the mixing tank. The first auger is located inside the sleeve, and the two second augers are located on opposite sides of the sleeve. A support assembly is provided below the mixing tank, and a tilting assembly for tilting the mixing tank is provided on the support assembly. A lifting platform is provided above the support assembly, and a lifting assembly is also provided on the mixing tank to move the lifting platform up and down by tilting the mixing tank.

[0008] Preferably, an addition pipe is fixedly connected to the mixing tank, and the addition pipe is located at the end of the mixing tank closer to the second motor.

[0009] Preferably, the support assembly includes a fixed base, on which a first support seat and a second support seat are fixedly connected. A first rotating shaft is rotatably connected to the first support seat, and one end of the first rotating shaft is fixedly connected to the mixing tank.

[0010] Preferably, the flipping assembly includes a first motor mounted on a fixed base, and the output shaft of the first motor is connected to a first rotating shaft via a belt and a pulley.

[0011] Preferably, the lifting assembly includes a second rotating shaft rotatably connected to a second support base, one end of the second rotating shaft being fixedly connected to a mixing tank, and the other end of the second rotating shaft being fixedly connected to a turntable. A connecting rod is rotatably connected to the turntable, and the end of the connecting rod away from the turntable is rotatably connected to a lifting platform.

[0012] Preferably, guide blocks are fixedly connected to both sides of the lifting platform, and guide rods are slidably connected to both guide blocks, with one end of the guide rods fixedly connected to the fixed base.

[0013] The beneficial effects of this utility model are as follows: 1. When the drive shaft is rotated by the second motor, the first auger can transport the powder from the bottom of the mixing tank to the top opening of the sleeve, and then throw it out by the second augers on both sides, forming a longitudinal circulation of the powder. The first motor drives the first rotating shaft to rotate through the belt drive, so that the mixing tank can be flipped 180 degrees back and forth, directly completing the position switching between the upper and lower layers of the powder in the tank. This allows the powder to be circulated and mixed in the longitudinal dimension, and the flipping can further break the layering state, which significantly improves the mixing effect and shortens the mixing time.

[0014] 2. The rotation of the second rotating shaft synchronously drives the turntable to rotate. The turntable pulls the lifting platform through the connecting rod to achieve stable lifting. The worker can stand on the lifting platform and adjust it to the height that matches the adding tube to easily complete the powder addition. The flipping action of the mixing tank is combined with the lifting needs of the worker's operating platform. There is no need to set up an additional independent lifting drive device, which simplifies the structure and significantly improves the convenience and safety of the feeding operation.

Detailed Implementation

[0020] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0021] A pharmaceutical powder spiral mixing device includes a mixing tank 1, which is a cylindrical structure with conical ends. A feed pipe 3 and a second motor 9 are respectively installed at both ends of the mixing tank 1, and the feed pipe 3 is connected to the mixing tank 1. The feed pipe 3 and the second motor 9 are respectively located at the narrow ends of the two cones. An addition pipe 2 is fixedly connected to the mixing tank 1, and the addition pipe 2 is located at the end of the mixing tank 1 near the second motor 9.

[0022] When the feed pipe 3 is at the bottom, the material can be discharged from the mixing tank 1 as a whole. The addition pipe 2 can pour multiple powders into the mixing tank 1 before the powder is mixed.

[0023] In this embodiment, the output shaft of the second motor 9 is equipped with a drive shaft 18, on which a first auger 19 and two second augers 20 are mounted. A sleeve 16 is provided inside the mixing tank 1, and a reinforcing rod 17 is fixedly connected to the sleeve 16. One end of the reinforcing rod 17 is fixedly connected to the mixing tank 1. The first auger 19 is located inside the sleeve 16, and the two second augers 20 are located on both sides of the sleeve 16.

[0024] The output shaft of the second motor 9 drives the drive shaft 18 to rotate, and the drive shaft 18 drives the first auger 19 to move inside the sleeve 16. Since the sleeve 16 is a tubular structure with open ends, the powder in the mixing tank 1 can be transported from the bottom opening of the sleeve 16 to the top opening under the action of the first auger 19, and then thrown out by the second auger 20, thereby completing the efficient mixing of the upper and lower layers of powder in the mixing tank 1.

[0025] The mixing tank 1 is provided with a support assembly below it. The support assembly includes a fixed base 8, on which a first support seat 4 and a second support seat 5 are fixedly connected. A first rotating shaft 6 is rotatably connected to the first support seat 4, and one end of the first rotating shaft 6 is fixedly connected to the mixing tank 1.

[0026] The first support base 4 supports the mixing tank 1 through the first rotating shaft 6, which enables the mixing tank 1 to be suspended above the fixed base 8, and there is enough space between the fixed base 8 and the mixing tank 1 to meet the rotation requirements of the mixing tank 1.

[0027] In this embodiment, the support assembly is provided with a flipping assembly for flipping the mixing tank 1. The flipping assembly includes a first motor 7 mounted on a fixed base 8. The output shaft of the first motor 7 is connected to the first rotating shaft 6 via a belt and a pulley.

[0028] The output shaft of the first motor 7 rotates, and the first rotating shaft 6 is driven to rotate by the belt and pulley, so that the first rotating shaft 6 can drive the mixing tank 1 to rotate back and forth 180 degrees.

[0029] After flipping, the powder deposited on the reinforcing rod 17 can be dropped off, and the powder in the mixing tank 1 can also switch between the upper and lower layers, improving the mixing effect of the powder.

[0030] In this embodiment, a lifting platform 13 is provided above the support assembly, and a lifting assembly is also provided on the mixing tank 1 to drive the lifting platform 13 to move up and down by flipping the mixing tank 1. The lifting assembly includes a second rotating shaft 10 rotatably connected to the second support base 5. One end of the second rotating shaft 10 is fixedly connected to the mixing tank 1, and the other end of the second rotating shaft 10 is fixedly connected to a turntable 11. A connecting rod 12 is rotatably connected to the turntable 11, and the end of the connecting rod 12 away from the turntable 11 is rotatably connected to the lifting platform 13.

[0031] When the mixing tank 1 rotates, the mixing tank 1 can drive the turntable 11 to rotate through the second rotating shaft 10, and drive the lifting platform 13 to move up and down with the help of the connecting rod 12. This allows the lifting platform 13 to lift the worker when the worker needs to pour the powder into the mixing tank 1, so that the worker can pour the powder into the mixing tank 1 through the adding pipe 2.

[0032] In this embodiment, guide blocks 14 are fixedly connected to both sides of the lifting platform 13, and guide rods 15 are slidably connected to both guide blocks 14, with one end of the guide rods 15 fixedly connected to the fixed base 8.

[0033] When the lifting platform 13 moves up and down, it can drive the guide block 14 to move up and down on the guide rod 15, guide the movement of the lifting platform 13, and improve the stability of the movement of the lifting platform 13.
