Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, and in particular to a mixing device for vitamin D2 production. Background Technology
[0002] In modern medicine and nutritional supplements, the production of vitamin D2 is crucial. As an essential nutrient, vitamin D2 plays a key role in the prevention and treatment of various diseases, such as rickets and osteoporosis, and is widely used in pharmaceuticals, health products, and food additives. Its production quality directly affects the efficacy and safety of downstream products; therefore, every stage of production is closely monitored. Raw material mixing, as a critical link, has a decisive impact on the quality of the final product.
[0003] In the production of vitamin D2, traditional mixing devices use a single-direction stirring shaft, which makes it difficult to achieve thorough mixing from all directions and angles. This can easily cause some raw materials to accumulate in specific areas of the tank, resulting in uneven mixing. Moreover, in the feeding stage, all raw materials are usually added to the mixing tank at once. Due to the variety and different properties of the raw materials, after being added at once, the differences in their characteristics, such as particle size, density, and flowability, make it difficult to disperse quickly and evenly in the initial stage of mixing, greatly prolonging the time required to achieve a uniform mixture. To address this technical problem, this application proposes a mixing device for vitamin D2 production. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing device for vitamin D2 production. Through the counter-rotation of the main mixing shaft and auxiliary mixing shaft, and the continuous stirring of the mixing fan blades, uniform mixing of raw materials is achieved. The batch-by-batch and stacked feeding method of the discharge plate further enhances the mixing effect and improves product quality. Simultaneously, pre-storing raw materials in proportion and discharging them in batches avoids uneven mixing, reduces mixing time, and significantly improves mixing efficiency.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A mixing device for vitamin D2 production includes a mixing tank. A stirring main shaft is rotatably connected to the middle of the bottom side of the mixing tank, and a stirring auxiliary shaft is rotatably connected to the inner wall of the bottom side of the mixing tank. The bottom ends of the stirring main shaft and the stirring auxiliary shaft are connected by a linkage assembly to control their rotation. A support frame is fixedly connected to the outer wall of the mixing tank, and a storage chamber is fixedly connected to the top of the support frame. A flow guide is fixedly connected to the bottom side of the storage chamber, and a discharge assembly is provided on the bottom side of the flow guide. The top of the stirring main shaft is connected to the discharge assembly via a gear set to control the feeding of raw materials. Baffles are provided on the inner walls of the storage chamber and the flow guide for classifying multiple raw materials.
[0007] Furthermore, the linkage assembly includes a first transmission gear fixedly connected to the bottom end of the stirring main shaft and a second transmission gear fixedly connected to the bottom end of the stirring auxiliary shaft, wherein the first transmission gear and the second transmission gear are meshed together.
[0008] Furthermore, a motor is mounted on the bottom side of the mixing tank via a fixing frame, and the drive end of the motor is fixedly connected to the bottom side of the transmission gear.
[0009] Furthermore, the discharge assembly includes a discharge plate rotatably connected to the bottom side of the flow guide, and the outer wall of the discharge plate is provided with a discharge hole.
[0010] Furthermore, the gear set includes a driven gear ring fixedly connected to the outer wall of the discharge plate and a driving gear fixedly connected to the top of the stirring main shaft, wherein the driven gear ring and the driving gear are meshed together.
[0011] Furthermore, stirring blades are fixedly connected to the outer walls of both the main stirring shaft and the auxiliary stirring shaft.
[0012] Furthermore, the top side of the storage chamber is provided with multiple conveying pipes for conveying raw materials.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this invention, the opposite rotation of the main stirring shaft and the auxiliary stirring shaft, along with the continuous stirring of the stirring blades, effectively achieves uniform mixing of different types of raw materials. Simultaneously, the rotation of the discharge plate and the batch feeding through the discharge holes allow the raw materials to enter the mixing tank in a stacked manner, further enhancing the mixing effect and ensuring the uniformity of raw material mixing during vitamin D2 production, thereby improving product quality.
[0015] 2. In this invention, raw materials are pre-stored in the space between the partition, storage chamber, and flow guide according to different proportions, and then added to the mixing tank in batches for mixing. This batch-by-batch, proportionate feeding method not only avoids the problem of uneven mixing that may be caused by adding raw materials all at once, but also reduces mixing time and improves the mixing efficiency of vitamin D2 production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figures 1-3This utility model provides an embodiment of a mixing device for vitamin D2 production, comprising a mixing tank 1, a stirring main shaft 2 rotatably connected to the middle of the bottom side of the mixing tank 1, a stirring auxiliary shaft 3 rotatably connected to the inner wall of the bottom side of the mixing tank 1, a transmission gear 8 fixedly connected to the bottom end of the stirring main shaft 2, and a transmission gear 9 fixedly connected to the bottom end of the stirring auxiliary shaft 3, the transmission gear 8 and the transmission gear 9 being meshed together, and a motor 13 mounted on the bottom side of the mixing tank 1 via a fixing frame, the drive end of the motor 13 being fixedly connected to the bottom side of the transmission gear 8 for controlling the stirring main shaft 2 and the stirring auxiliary shaft. The mixing tank 1 is rotated. A support frame 15 is fixedly connected to the outer wall of the mixing tank 1. A storage chamber 5 is fixedly connected to the top of the support frame 15. A guide hood 16 is fixedly connected to the bottom side of the storage chamber 5. A discharge plate 11 is rotatably connected to the bottom side of the guide hood 16. A discharge hole 12 is opened on the outer wall of the discharge plate 11. A driven gear ring 6 is fixedly connected to the outer wall of the discharge plate 11 and a drive gear 4 is fixedly connected to the top of the mixing main shaft 2. The driven gear ring 6 and the drive gear 4 are meshed to control the feeding of production raw materials. A partition 10 is provided on the inner wall of the storage chamber 5 and the guide hood 16 to classify multiple raw materials.
[0023] Specifically, in the vitamin D2 production process, different types of raw materials are transported to the storage chamber 5 and the flow guide shroud 16 via the conveying pipe 7. The partition 10 separates the raw materials into different spaces. Then, the motor 13 is started, driving the transmission gear 8 and transmission gear 9 to mesh, thereby controlling the stirring main shaft 2 and the stirring auxiliary shaft 3 to rotate in opposite directions, resulting in better mixing for vitamin D2 production. The driving gear 4 at the top of the stirring main shaft 2 meshes with the driven gear ring 6, driving the discharge plate 11 to rotate at the bottom of the flow guide shroud 16. By changing the position of the discharge hole 12 to correspond sequentially to the spaces separated by different partitions 10, the corresponding raw materials are added to the mixing tank 1 in batches, achieving cumulative raw material addition. During the raw material addition process, the stirring blades 14 on the stirring main shaft 2 and the stirring auxiliary shaft 3 continuously rotate, uniformly mixing the raw materials. Simultaneously, according to production needs, raw materials can be pre-stored in different proportions in the space between the partitions 10, the storage chamber 5, and the flow guide shroud 16, and then sequentially added to the mixing tank 1 for mixing. This process effectively improves the mixing efficiency of vitamin D2 production.
[0024] Reference Figures 1-3 The outer walls of the main mixing shaft 2 and the auxiliary mixing shaft 3 are both fixedly connected with mixing blades 14, and multiple conveying pipes 7 are provided on the top side of the storage chamber 5 for conveying raw materials;
[0025] Specifically, the mixing of vitamin D2 during production can be achieved by stirring the fan blades 14, thereby improving the efficiency of mixing during vitamin D2 production.
[0026] Working principle: Raw materials are conveyed to the storage chamber 5 and the guide shroud 16 through the conveying pipe 7. Different types of raw materials are separated by the partition 10. The starting motor 13 controls the meshing between the transmission gear 8 and the transmission gear 9 to control the rotation of the stirring main shaft 2 and the stirring auxiliary shaft 3 in opposite directions. The top of the rotating stirring main shaft 2 controls the rotation of the discharge plate 11 at the bottom of the guide shroud 16 through the meshing between the driving gear 4 and the driven gear ring 6, changing the space of the discharge hole 12 separated by different partitions 10, and putting the corresponding materials into the mixing tank 1. Through the transmission ratio between the driving gear 4 and the driven gear ring 6, the production materials inside the storage chamber 5 and the guide shroud 16 are fed into the mixing tank 1 in batches. Different types of raw materials are fed into the mixing tank 1 in a stacked manner. With the rotation of the stirring main shaft 2 and the stirring auxiliary shaft 3, and the stirring fan blades 14, the raw materials for vitamin D2 production are uniformly mixed. At the same time, according to different proportions, the raw materials are stored in the space between the partition 10, the storage chamber 5 and the guide shroud 16, and then put into the mixing tank 1 for mixing. This can improve the mixing efficiency of vitamin D2 production.
