Description

Technical Field

[0001] The present application relates to the technical field of powder production, and particularly relates to a material mixing device for powder production. Background Art

[0002] In the production process of powder, the uniformity of material mixing plays a crucial role in the quality and performance of the final product.

[0003] However, in the feeding process of existing powder mixing equipment, pipeline transportation or manual feeding is usually adopted, resulting in that it is often difficult to ensure the uniform distribution of materials in the feeding bin during the feeding process. Especially when dealing with powders with poor fluidity and easy caking, the phenomenon of uneven feeding is particularly prominent. Uneven feeding will lead to too high or too low local concentration of materials during the mixing process, thus affecting the mixing effect and product uniformity.

[0004] In addition, traditional feeding bins often ignore the problem of powder residue on the inner wall. During long-term use, a certain amount of powder will accumulate on the inner wall of the feeding bin. These residues will not only cause waste of materials, but also be mixed into new materials during the next feeding, further affecting the mixing effect and product purity.

[0005] In view of the above problems, a material mixing device for powder production is now designed. Utility Model Content

Specific embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0027] The embodiment of the present application provides a material mixing device for the production of powder and bulk drugs, which can solve the problem in the related art that it is often difficult to ensure the uniform distribution of powder and bulk drug materials with poor fluidity and easy caking in the feeding bin during the feeding process.

[0028] Please refer to Figures 1 - 3 , a material mixing device for the production of powder and bulk drugs includes; a mounting frame 1, a mixing mechanism 2, and a feeding mechanism 3. The mixing mechanism 2 is used for mixing powder and bulk drugs, and the feeding mechanism 3 is used for feeding materials to the mixing mechanism 2;

[0029] The feeding mechanism 3 includes a tipping frame 31, a feeding bin 32, and a delivery pipe 33. The feeding bin 32 is arranged on the mounting frame 1. The tipping frame 31 is connected to the feeding bin 32 and is used to tip the feeding bin 32. One end of the delivery pipe 33 communicates with the feeding bin 32, and the other end of the delivery pipe 33 extends above the mixing mechanism 2;

[0030] A scraping mechanism 4 is provided inside the feeding bin 32 for scraping the powdery and granular raw materials on the inner wall of the feeding bin 32;

[0031] The scraping mechanism 4 includes a driving member 41 and a scraping member 42. The driving member 41 is connected to the scraping member 42 and is used to drive the scraping member 42 to rotate.

[0032] It should be noted that the driving member 41 includes a driving motor and a speed reducer

[0033] When feeding the mixing mechanism 2, load the powdery and granular raw materials to be mixed into the feeding bin 32. The tipping frame 31 is connected to the feeding bin 32 through its connecting mechanism. When receiving the feeding instruction, the tipping frame 31 starts to act, tipping the feeding bin 32 to an appropriate angle, so that the powdery and granular materials fall into the delivery pipe 33 under the action of gravity.

[0034] During this process, the scraping mechanism 4 works synchronously. The driving member 41 drives the scraping member 42 to rotate, dispersing the internal powdery and granular raw materials to make them uniform.

[0035] As a channel connecting the feeding bin 32 and the mixing mechanism 2, the delivery pipe 33 is designed to ensure that the powdery and granular materials can be smoothly transported from the feeding bin 32 to the feed inlet above the mixing mechanism 2. Repeat the above steps to sequentially feed various powdery and granular raw materials into the mixing mechanism 2.

[0036] During or after the feeding process, the scraping mechanism 4 starts to work. The driving member 41, including a driving motor and a speed reducer, provides stable rotational power.

[0037] The scraping member 42 is connected to the driving member 41 and rotates inside the feeding bin 32 under its drive. The scraper on the scraping member 42 closely adheres to the inner wall of the feeding bin 32, gradually scraping off the powdery and granular residues adhering to the inner wall as it rotates.

[0038] The scraped powdery and granular materials fall to the bottom of the feeding bin 32 under the action of gravity, and are then taken away during the feeding process or collected and processed, thus realizing the cleaning of the inner wall of the feeding bin 32.

[0039] Through the tipping frame 31, the feeding bin 32, and the scraping mechanism 4, it can be ensured that the powdery and granular materials are evenly distributed during the feeding process, avoiding the problems of too high or too low local concentration that may occur during the feeding process, thereby improving the mixing effect and product consistency.

[0040] At the same time, the introduction of the scraping mechanism 4 effectively solves the problem of powder residue on the inner wall of the feeding bin 32, reduces material waste, and improves the utilization rate of raw materials.

[0041] Regularly removing the residues on the inner wall of the feeding bin 32 helps to keep the equipment clean and sanitary, reduces wear and corrosion on the equipment, and prolongs the service life of the equipment.

[0042] In another embodiment, the delivery pipe 33 includes a feeding pipe and a feeding box which are interconnected, and a plurality of through holes are formed at the bottom of the feeding box.

[0043] The feeding pipe is a part of the conveying pipe 33, and is mainly responsible for guiding the powder from the feeding bin 32 to the feeding box.

[0044] The feeding box is located below the feeding pipe and is connected to the feeding port above the mixing mechanism 2.

[0045] The number, size and distribution of the through holes at the bottom of the feeding box are carefully calculated and designed to ensure that the powder can evenly and stably fall into the mixing mechanism 2 through the through holes. This decentralized feeding method helps to reduce the agglomeration and agglomeration of materials during the feeding process and improve the mixing effect.

[0046] Specifically, the flip frame 31 in this embodiment includes a support frame 311 arranged on the mounting frame 1, the feeding bin 32 is rotatably arranged on the support frame 311, and a cylinder 312 is hingedly arranged on the mounting frame 1, and the output shaft of the cylinder 312 is hinged to one end of the feeding bin 32.

[0047] Initial state: before feeding, the feeding bin 32 is in an initial position, usually horizontal or inclined at a certain angle, and the cylinder 312 is in an inoperative state. At this time, the feeding bin 32 is filled with the powder to be mixed.

[0048] Turning action: When feeding is required, the control system sends a command to the cylinder 312, and the cylinder 312 starts to work. Its output shaft extends or retracts, and is connected to the feeding bin 32 through the hinge point, thereby driving the feeding bin 32 to turn around the rotation point on the support frame 311. The turning angle and speed can be adjusted according to actual needs.

[0049] Feeding process: As the feeding bin 32 turns over, the powder gradually falls into the conveying pipe 33 under the action of gravity, and is transported to the feeding port above the mixing mechanism 2 through the conveying pipe 33. During the feeding process, the working state of the cylinder 312 can be adjusted as needed to control the feeding speed and feeding amount.

[0050] Reset action: After the feeding is completed, the cylinder 312 receives the control signal again, and its output shaft moves in the reverse direction, driving the feeding bin 32 to reset to the initial position, preparing for the next feeding.

[0051] Specifically, the scraping member 42 in this implementation scheme includes a rotating shaft rotatably arranged inside the feeding bin 32. A scraping plate is arranged on the rotating shaft, and the other end of the scraping plate is attached to the inner wall of the feeding bin 32.

[0052] When the rotating shaft rotates under the drive of the driving member 41, the scraping plate rotates accordingly and closely adheres to the inner wall of the feeding bin 32. During the rotation process, the scraping plate continuously scrapes the inner wall surface, scraping off the powder residue adhering to the inner wall.

[0053] The scraped powder residue falls to the bottom of the feeding bin 32 under the action of gravity, and then can be taken away through the next feeding process or collected and processed through a dust collection device.

[0054] The scraping member 42 can continuously work during the entire feeding and mixing process to ensure that the inner wall of the feeding bin 32 always remains clean. This helps to improve the mixing effect, reduce material waste, and extend the service life of the equipment.

[0055] In one embodiment, the mixing mechanism 2 includes a rotating member 21, a mixing box 22, and a stirrer 23. The mixing box 22 is arranged on the mounting frame 1. The rotating member 21 is connected to the mixing box 22 and is used to drive the mixing box 22 to rotate. The stirrer 23 is arranged inside the mixing box 22 and is used to stir the materials.

[0056] Before the feeding starts, the stirrer 23 rotates or reciprocates inside the mixing box 22 to stir and mix the materials. The stirring action of the stirrer 23 can break the agglomeration and caking phenomena among the materials and promote the uniform mixing of the materials. The stirring speed and time can also be adjusted as needed.

[0057] When necessary, the rotating member 21 starts to work, driving the mixing box 22 to perform a reciprocating rotation motion to promote the dispersion and mixing of the materials in the horizontal direction. The rotation speed and time can be adjusted according to the characteristics of the materials and the mixing requirements.

[0058] Mixing completed: After a period of rotation and stirring and mixing, the materials reach the expected mixing effect in the mixing box 22.

[0059] At this time, the work of the rotating member 21 and the stirrer 23 can be stopped, and the mixing box 22 is tilted to one end through the rotating member 21, and the mixed materials are discharged from the mixing box 22 through the discharge valve.

[0060] Specifically, a feeding hopper 5 located below the conveying pipe 33 is arranged at the top of the mixing box 22. A plurality of partition bars 6 are arranged inside the feeding hopper 5, and a discharge valve is arranged on the mixing box 22.

[0061] The feed hopper 5 serves as a transition structure for the material to enter the mixing tank 22 from the conveying pipe 33, and its shape and size need to be designed according to the outlet size of the conveying pipe 33 and the inlet requirements of the mixing tank 22.

[0062] The partition bars 6 can divide the internal space of the feed hopper 5 into multiple small areas. When the material enters the feed hopper 5 from the conveying pipe 33, these partition bars 6 will force the material to disperse and recombine in multiple directions. The advantages of doing so are: promoting the uniform distribution of the material,

[0063] Furthermore, it should be noted that the rotating member 21 in this embodiment includes support seats oppositely arranged on the mounting frame 1. A second rotating shaft is rotatably arranged on the support seats. The mixing tank 22 is arranged between the two second rotating shafts. A second driving member is arranged on any one of the support seats. The second driving member is connected to any one of the output shafts and is used to drive the second rotating shaft to rotate.

[0064] The second driving member includes a driving motor and a speed reducer.

[0065] When mixing materials is required, first start the driving motor. The driving motor starts to operate and adjusts the rotational speed to a suitable range through the speed reducer. The speed reducer transmits the adjusted power to the second rotating shaft connected thereto. As the second rotating shaft rotates reciprocally, the mixing tank 22 also rotates on the horizontal plane. The materials in the mixing tank 22 are thrown towards the tank wall and collide and rub against each other, thereby achieving mixing.

[0066] During the mixing process, the rotational speed of the driving motor can be adjusted according to the characteristics of the materials and the mixing requirements. By changing the rotational speed, the rotational speed and direction of the mixing tank 22 can be controlled, thereby affecting the mixing effect and mixing time of the materials.

[0067] In addition, by rotating the mixing tank 22 to a certain inclination angle, it is beneficial for the materials inside the mixing tank 22 to flow out.

[0068] As Figure 4 shown, in a preferred embodiment, the stirrer 23 includes a third driving member 231, a rotating rod 232, and four groups of stirring paddles 233. The third driving member 231 is connected to the rotating rod 232 and is used to drive the rotating rod 232 to rotate. The rotating rod 232 is rotatably arranged inside the mixing tank 22. The four groups of stirring paddles 233 are arranged in a ring on the rotating rod 232, and the four groups of stirring paddles 233 are staggered along the length direction of the rotating rod 232; the stirring paddles 233 are connected to the rotating rod 232 by bolts, and the installation angle of each group of the stirring paddles 233 is different. The third driving member 231 includes a driving motor and a speed reducer.

[0069] The four groups of stirring paddles 233 are staggered along the length direction of the rotating rod 232, which helps to form a complex flow pattern during the stirring process and improve the mixing effect.

[0070] Each set of stirring paddles 233 is bolted to the rotating rod 232 for easy installation, disassembly and replacement.

[0071] In addition, the installation angles of each set of stirring paddles 233 are different, which further enhances the complexity of stirring and the mixing effect.

[0072] When it is necessary to stir the material, the drive motor is started first. The drive motor adjusts the rotational speed to a suitable range through a reducer and transmits the power to the rotating rod 232. As the drive motor operates, the rotating rod 232 begins to rotate. Since the stirring paddles 233 are fixed to the rotating rod 232, they also rotate together. During the rotation process, the stirring paddles 233 stir the material in the mixing tank 22. Due to the fact that the number, layout and installation angles of the stirring paddles 233 are carefully designed, they can form a complex flow pattern in the mixing tank 22 to promote the uniform mixing of the material. At the same time, the rotation of the stirring paddles 233 will also generate a certain shear force and impact force, which helps to break the agglomeration and caking phenomena between the materials.

[0073] During the stirring process, the rotational speed of the drive motor can be adjusted according to the characteristics of the material and the mixing requirements. By changing the rotational speed, the stirring speed and intensity of the stirring paddles 233 can be controlled, thereby affecting the mixing effect and mixing time of the material.
