Description

Technical Field

[0001] This utility model belongs to the technical field of riboflavin production equipment, specifically relating to an oxygen carrier-enhanced riboflavin fermentation raw material pretreatment mixing device. Background Technology

[0002] In the process of oxygen-carrier-enhanced riboflavin fermentation, raw materials need to be added to a mixing device for stirring and mixing. Since riboflavin production raw materials are mostly powders, they tend to clump during long-term storage. Directly adding them to the mixing device results in poor mixing effect and low mixing efficiency. Furthermore, the powder easily adheres to the inner wall of the mixing device, causing contamination, which can negatively impact the quality of riboflavin over time. Therefore, there is an urgent need for an oxygen-carrier-enhanced riboflavin fermentation raw material pretreatment and mixing device to solve these technical problems. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an oxygen carrier-enhanced riboflavin fermentation raw material pretreatment mixing device, comprising a horizontal mixing cylinder, a feed hopper at one end of the top of the mixing cylinder, a discharge pipe at one end of the bottom of the mixing cylinder, and a switch valve on the discharge pipe; a feed pipe is provided on the feed hopper, a stirring assembly one is provided inside the feed hopper, and a stirring assembly two is provided inside the mixing cylinder; The stirring assembly includes a vertical rotating shaft, the upper end of which passes through the feed hopper and is connected to a motor. A stirring rod is fixed on the vertical rotating shaft located inside the feed hopper. The second stirring assembly includes a horizontal rotating shaft. One end of the horizontal rotating shaft passes through the mixing cylinder and is connected to a second motor. A second stirring rod is fixed on the horizontal rotating shaft inside the mixing cylinder. A scraper is fixed on the second stirring rod. The scraper contacts the inner wall of the mixing cylinder to prevent material from sticking to the inner wall of the mixing cylinder.

[0004] The raw materials to be mixed are poured into the feed hopper, where they are broken up by the first stirring rod and then sent into the mixing cylinder. After being mixed by the second stirring rod, they are discharged from the discharge pipe.

[0005] Preferably, the lower end of the feed hopper is fixed with a discharge pipe, which extends into the mixing cylinder. A matching feeding screw is provided inside the discharge pipe, and the upper end of the feeding screw is fixedly connected to a vertical rotating shaft. The feeding screw and the discharge pipe cooperate to form a feeding auger, which can send the material in the feed hopper into the mixing cylinder and avoid blockage of the discharge pipe.

[0006] Preferably, the mixing cylinder has an elongated feed inlet at its top. The feed hopper is movably positioned above the feed inlet via a movable assembly, which includes a horizontal screw and a guide rod. The guide rod and the horizontal screw are parallel to the length direction of the feed inlet. Connecting plates are fixedly connected to both ends of the guide rod, and the two connecting plates are fixed to the mixing cylinder. Both ends of the horizontal screw are rotatably connected to the corresponding connecting plates via bearings. One end of the horizontal screw passes through the connecting plate and is connected to a reversible motor. A slider is slidably mounted on the guide rod, and a slider is threaded onto the horizontal screw. Both sliders are fixedly connected to the outer wall of the feed hopper. The reversible rotation of the motor drives the horizontal screw to rotate in both directions, causing the feed hopper to move reciprocally along the horizontal screw. This ensures that the raw material in the feed hopper is more evenly distributed into the mixing cylinder, preventing the material from settling in a fixed position within the mixing cylinder during feeding, which would affect the mixing effect and efficiency.

[0007] Preferably, the feed inlet is provided with a matching dustproof cloth or a detachable cover plate, one end of which is connected to one end of the feed inlet, and the other end of which is connected to the feed hopper. The dustproof cloth and cover plate can provide some protection to the feed inlet, reducing material spillage during mixing and minimizing air pollution.

[0008] Preferably, the mixing cylinder has arc-shaped frames fixedly connected to its left and right ends, respectively. Each of the two arc-shaped frames is connected to a support bracket (first bracket) and a support bracket (second bracket). Support bracket first is positioned near the discharge pipe, and its top is hinged to the corresponding arc-shaped frame. Support bracket second is telescopic, and is a hydraulic or pneumatic cylinder. The telescopic end of support bracket second is vertically upward and hinged to the corresponding arc-shaped frame. When the mixing cylinder discharges material, support bracket second extends, lowering the end of the mixing cylinder near the discharge pipe and raising the end away from the discharge pipe, facilitating material discharge from the discharge pipe.

[0009] This invention also includes other components that enable the normal operation of a pretreatment mixing device for oxygen carrier-enhanced riboflavin fermentation feedstock, such as control components for motor one and motor two, which are all conventional technologies and equipment in the field. Furthermore, devices or components not specified in this invention, such as switching valves, horizontal screws, scrapers, feeding screws, hydraulic cylinders, or pneumatic cylinders, all employ conventional technologies and equipment in the field.

[0010] This invention has the following advantages: it can break up the raw materials before mixing, making the feeding more uniform, improving the mixing effect and efficiency, reducing material stickiness, and making the discharge more complete and efficient. Attached Figure Description

[0014] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0015] Example 1 like Figure 1-2 As shown, this utility model provides a pretreatment mixing device for oxygen carrier-enhanced riboflavin fermentation raw materials, including a horizontal mixing cylinder 1, a feeding hopper 5 at one end of the top of the mixing cylinder 1, a discharge pipe 7 at one end of the bottom of the mixing cylinder 1, and a switch valve on the discharge pipe 7; a feeding pipe 6 is provided on the feeding hopper 5, a stirring assembly 1 is provided inside the feeding hopper 5, and a stirring assembly 2 is provided inside the mixing cylinder 1; The stirring assembly includes a vertical rotating shaft 14, the upper end of which passes through the feed hopper 5 and is connected to a motor 13. A stirring rod 15 is fixed on the vertical rotating shaft 14 located inside the feed hopper 5. The second stirring assembly includes a horizontal rotating shaft 17. One end of the horizontal rotating shaft 17 passes through the mixing cylinder 1 and is connected to a second motor 4. A second stirring rod 19 is fixed on the horizontal rotating shaft 17 located inside the mixing cylinder 1. A scraper 18 is fixed on the second stirring rod 19. The scraper 18 contacts the inner wall of the mixing cylinder 1 to prevent materials from sticking to the inner wall of the mixing cylinder 1.

[0016] The lower end of the feed hopper 5 is fixed with a discharge pipe, which extends into the mixing cylinder 1. A matching feeding screw 16 is provided inside the discharge pipe. The upper end of the feeding screw 16 is fixedly connected to the vertical rotating shaft 14. The feeding screw 16 and the discharge pipe cooperate to form a feeding auger, which can send the material in the feed hopper 5 into the mixing cylinder 1 and avoid clogging of the discharge pipe.

[0017] During operation, the raw materials to be mixed are poured into the feed hopper 5, and after being broken up by the stirring rod 15 in the feed hopper 5, they are sent into the mixing cylinder 1, and after being mixed by the stirring rod 19, they are discharged from the discharge pipe 7.

[0018] Example 2 like Figure 3-5 As shown, the difference between this embodiment and Embodiment 1 is that the top of the mixing cylinder 1 is provided with a long strip-shaped feed inlet 21, and the feed hopper 5 is movably arranged above the feed inlet 21 by a moving component. The moving component includes a horizontal screw 8 and a guide rod 20. The guide rod 20 and the horizontal screw 8 are parallel to the length direction of the feed inlet. The two ends of the guide rod 20 are respectively fixedly connected to connecting plates 9, and the two connecting plates 9 are fixed on the mixing cylinder 1. The two ends of the horizontal screw 8 are respectively rotatably connected to the corresponding connecting plates 9 through bearings. One end of the horizontal screw 8 passes through the connecting plate 9 and is connected to a reversible motor 10. A slider 1 is slidably sleeved on the guide rod 20, and a slider 2 11 is threadedly fitted on the horizontal screw 8. Both slider 1 and slider 2 11 are fixedly connected to the outer wall of the feed hopper 5.

[0019] During operation, the raw materials to be mixed are poured into the feed hopper 5, where they are broken up by the stirring rod 15 and fed into the mixing cylinder 1. After being mixed by the stirring rod 19, they are discharged from the discharge pipe 7. During the above operation, when feeding, the forward and reverse rotation of the motor 10 drives the horizontal screw 8 to rotate in both directions, thereby causing the feed hopper 5 to move back and forth along the horizontal screw 8. This ensures that the raw materials in the feed hopper 5 are more evenly distributed into the mixing cylinder 1, preventing the raw materials from falling into a fixed position in the mixing cylinder 1 during feeding, which would affect the mixing effect and efficiency.

[0020] Example 3 like Figure 3 , 4As shown in Figure 6, the difference between this embodiment and Embodiment 2 is that a matching detachable cover plate 22 is provided at the feed inlet 21. The cover plate 22 can provide a certain degree of shielding for the feed inlet 21, reducing material overflow during mixing and minimizing air pollution. After feeding is completed, the feed hopper is moved to one end of the feed inlet, the cover plate is closed, and mixing can then commence.

[0021] Example 4 like Figure 3 , 4 As shown, the difference between this embodiment and Embodiment 2 is that a matching dustproof cloth is provided at the feed inlet 21. One end of the dustproof cloth is connected to one end of the feed inlet 21, and the other end of the dustproof cloth is connected to the feed hopper 5. The dustproof cloth can provide a certain degree of shielding for the feed inlet 21. It does not need to be disassembled when the feed hopper moves, does not affect the movement of the feed hopper, reduces the spillage of materials during mixing, and reduces air pollution.

[0022] Example 5 like Figure 1-2 As shown, the difference between this embodiment and Embodiment 2 is that the mixing cylinder 1 has arc-shaped frames 12 connected to its left and right ends respectively. Each of the two arc-shaped frames 12 is connected to a first support 2 and a second support 3. The first support 2 is positioned close to the discharge pipe 7, and its top is hinged to the corresponding arc-shaped frame 12. The second support 3 is telescopic and is a hydraulic or pneumatic cylinder. The telescopic end of the second support 3 is vertically upward and hinged to the corresponding arc-shaped frame 12. When the mixing cylinder 1 discharges material, the second support 3 extends, lowering the end of the mixing cylinder 1 closest to the discharge pipe 7 and raising the end of the mixing cylinder 1 furthest from the discharge pipe 7, facilitating material discharge from the discharge pipe 7.

[0023] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
