Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical manufacturing technology, specifically to a tubular continuous mixer for pharmaceutical manufacturing. Background Technology

[0002] Biopharmaceuticals refer to products manufactured using research findings in microbiology, biology, medicine, and biochemistry, utilizing the principles and methods of microbiology, chemistry, biochemistry, biotechnology, and pharmacy to prevent, treat, and diagnose diseases from organisms, tissues, cells, organs, and body fluids. Biopharmaceutical raw materials are primarily natural biological materials, including microorganisms, human organisms, animals, plants, and marine organisms. A pharmaceutical mixer is a machine used to mix two or more drugs uniformly in a specific ratio. The main structure of this machine includes a main body, a mixing drum, a stirrer, and a sealing cap. Uniform mixing of the drugs is achieved through the rotation of the stirrer.

[0003] To better balance drug efficacy, medications are mixed. Existing drug mixers are mostly rectangular or V-shaped, occupying a large area and having hard-to-clean corners. This can easily lead to blockages at the inlet during drug delivery and mixing, requiring manual cleaning. With a wide variety of drugs and different mixing requirements, the existing mixers use fixed stirring blades, making it impossible to adjust the blade angle according to different needs, resulting in slower subsequent drug mixing efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a tubular continuous mixer for pharmaceutical use, which solves the technical problem that the inlet is easily blocked during drug delivery and mixing, requiring manual cleaning and inspection. There are many types of drugs and different mixing requirements. The original mixer uses fixed stirring blades to mix the drugs, which makes it impossible to adjust the angle of the blades according to different needs, resulting in slow drug mixing efficiency.

A through slot is opened at the rear end of the mixing cylinder, which is used to connect to the device inlet. An extension cylinder is added to the rear end of the mixing cylinder to flexibly adjust the mixing time of the medicine. The stirring blades are connected by an adjusting gear, which meshes with the transmission gear to rotate, allowing for lateral angle adjustment of the stirring blades.

[0028] like Figures 1-4 As shown, a tubular continuous mixer for pharmaceutical use is illustrated in one embodiment of the present invention, comprising: a mounting frame 1, a mixing cylinder 2 fixedly mounted on the upper end of the mounting frame 1, a rotating motor 17 fixedly mounted on the front end of the mixing cylinder 2, and a rotating rod 18 rotatably connected to the rear end of the rotating motor 17, a groove 19 fixedly opened on the upper end of the rotating rod 18, a splicing rod 20 fixedly mounted on the rear end of the rotating rod 18, a transmission gear 21 fixedly connected inside the groove 19, an adjusting gear 22 meshing with the upper end of the transmission gear 21, a stirring blade 23 rotatably connected to the upper end of the adjusting gear 22, and a connecting hole 24 fixedly opened inside the stirring blade 23;

[0029] The spiral blade 25 is fixedly connected to the rear end of the splicing rod 20, and the spiral blade 25 has a mounting groove 26 fixedly opened inside.

[0030] For example, such as Figure 2 As shown, an inlet 3 is fixedly opened at the upper end of the mixing cylinder 2, a first connecting plate 4 is fixedly connected to the rear of the upper end of the mixing cylinder 2, a through slot 5 is fixedly opened at the rear end of the interior of the mixing cylinder 2, an extension cylinder 6 is fixedly connected to the rear end of the through slot 5, a second connecting plate 7 is fixedly connected to the upper end of the extension cylinder 6, and a device port 8 is fixedly opened at the front of the interior of the extension cylinder 6.

[0031] For example, such as Figure 4 As shown, the rotating rod 18 is connected to the mixing cylinder 2 through the rotating motor 17. There are three grooves 19. The diameter of the splicing rod 20 is smaller than the diameter of the rotating rod 18, and the upper end of the splicing rod 20 is fixedly provided with a screw hole.

[0032] For example, such as Figure 4 As shown, the adjusting gear 22 is symmetrically installed on the left and right sides of the connecting rod with the internal connecting rod as the center reference. The stirring blade 23 is fan-shaped. The adjusting gear 22 is rotatably connected to the stirring blade 23 through the connecting hole 24. The mounting groove 26 is interlocked with the splicing rod 20.

[0033] For example, such as Figure 2As shown, the through slot 5 and the device port 8 are connected by a connecting plate to form a flange connection, and the through slot 5 and the device port 8 are connected by an insertion connection. The lower ends of the extension cylinder 6 and the mixing cylinder 2 are both equipped with discharge ports.

[0034] In some examples, the mixing cylinder 2 is the main mixing chamber, with an inlet 3 at the top front and a detachable plate at the rear. The drug enters the mixing cylinder 2 through the inlet 3. The rotating motor 17 drives the rotating rod 18 to rotate, and the stirring blades 23 at the top of the rotating rod 18 are used to evenly mix the drug in the mixing cylinder 2. In order to mix drugs with different requirements, the rotating rod 18 has a built-in groove 19 to accommodate a gear set. The transmission gear 21 in the groove 19 of the rotating rod 18 meshes with the adjusting gear 22, and the angle of the stirring blades 23 is adjusted in real time through gear transmission. A splicing rod 20 is installed at the rear end of the rotating rod 18. The rotating rod 18 is connected to the spiral blade 25 through the splicing rod 20 to form two mixing areas, which are used to process different requirements in stages. The particles are mixed first and then homogenized. A through slot 5 is added to the rear end of the mixing cylinder 2. The through slot 5 is connected to the device port 8 through a flange through a connecting plate. The mixing cylinder 2 can be quickly connected to the extension cylinder 6 through the through slot 5 to extend the drug mixing time.

[0035] For example, such as Figure 3 As shown, a tubular continuous mixer for pharmaceutical use is provided in another embodiment of the present invention, comprising: an inlet 3 with a pouring trough 9 fixedly opened at the upper end; a conveying pipe 10 fixedly installed at the upper end of the pouring trough 9; a flexible hose 11 fixedly installed at the lower end of the pouring trough 9; a movable frame 12 fixedly connected to the outer side of the flexible hose 11; a fixed plate 13 fixedly installed at the rear end of the movable frame 12; a spring rod 14 fixedly connected to the rear end of the fixed plate 13; a sliding plate 15 fixedly installed at the rear end of the spring rod 14; and a vibration motor 16 fixedly installed at the rear end of the sliding plate 15.

[0036] For example, such as Figure 3 As shown, the rotating rod 18 is connected to the mixing cylinder 2 through the rotating motor 17. There are three grooves 19. The diameter of the splicing rod 20 is smaller than the diameter of the rotating rod 18, and the upper end of the splicing rod 20 is fixedly provided with a screw hole.

[0037] For example, such as Figure 3 As shown, the fixed plate 13 is L-shaped, and the spring rod 14 is slidably connected to the fixed plate 13 through the sliding plate 15. The spring rod 14 is symmetrically installed on the left and right sides of the fixed plate 13 with the fixed plate 13 as the center reference.

[0038] In some examples, the pouring tank 9 is connected to the inlet 3 of the mixing cylinder 2, serving as a transition channel for drug delivery. The delivery pipe 10 delivers the drug into the pouring tank 9. A flexible hose 11 structure is added to the middle section of the pouring tank 9. The hose 11 is made of flexible material (silicone) and can deform under vibration to prevent material adhesion. The moving frame 12 is wrapped around the outside of the hose 11 and is fixed to the hose 11 with screws. Vibration drives the hose 11 to move. A pressure sensor is added inside the pouring tank 9. The pressure sensor detects a blockage signal and starts the vibration motor 16. The pressure sensor is an MPX2010. The vibration motor 16 provides high-frequency vibration, which is transmitted to the moving frame 12 through the sliding plate 15 and the spring rod 14, causing the hose 11 to deform and breaking the blockage of the drug inside the pouring tank 9.
