Description

Technical Field

[0001] This application relates to the field of feed fermentation technology, and more specifically, to a fermentation apparatus for feed production. Background Technology

[0002] In the feed production sector, fermentation technology plays a crucial role in improving feed quality, increasing its nutritional value, and enhancing its palatability. Stirred fermentation reactors, as a common fermentation device, are widely used in various feed production enterprises.

[0003] Chinese patent CN217895571U discloses a feed fermentation device for feed production. The fermentation device has a servo motor fixedly installed on the fermentation tank, and a stirring shaft is fixedly installed at the output end of the servo motor. The stirring shaft is driven to rotate by the servo motor to mix the feed materials and bacteria in the fermentation tank.

[0004] However, the stirring structure used in the above-mentioned feed fermentation device is relatively simple and its stirring method is singular. When stirring the feed materials and inoculum in the fermentation tank, the efficiency is relatively low. Due to the limited stirring path, the materials are difficult to form sufficient and effective convection and diffusion in the tank, which makes it impossible for the feed materials and inoculum to achieve deep mixing, thus delaying the fermentation process and affecting the overall fermentation efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a fermentation device for feed production, which can solve the technical problem that the existing feed fermentation devices have a simple stirring structure, low stirring efficiency of feed materials and bacteria in the fermentation tank, difficulty in fully mixing, and reduced fermentation efficiency.

[0006] This application provides a fermentation device for feed production, including a tank.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Specific implementation examples:

[0027] like Figure 1 and Figure 2 As shown, this application provides a fermentation device for feed production, including a tank 1. A feed hopper 2 is located at the top of the tank 1, and a discharge pipe 3 is located at the bottom of the tank 1. A discharge valve 4 is installed on the discharge pipe 3. A protective cylinder 5 is located at the top inside the tank 1. A support plate 6 is rotatably connected to the lower end of the protective cylinder 5. A first drive assembly 7 is provided on the tank 1 to drive the support plate 6 to rotate. Two stirring components 8 are symmetrically rotatably arranged on the support plate 6. A second drive assembly 9 is located on the support plate 6 inside the protective cylinder 5 to drive the two stirring components 8 to rotate simultaneously. In use, feed materials and inoculum enter the tank 1 through the feed hopper 2 at the top of the tank 1. The first drive assembly 7... The drive support plate 6 rotates, causing the stirring component 8 on the support plate 6 to move in a circular motion around the central axis of the tank 1 in the horizontal direction, expanding the stirring coverage and helping to stir materials in different positions within the tank 1. At the same time as the support plate 6 rotates, the second drive component 9 located inside the protective cylinder 5 starts to work, driving the two stirring components 8 to rotate simultaneously, stirring and mixing the feed materials and inoculum. Compared with the single stirring method in the prior art, this effectively improves the stirring efficiency and can mix the feed materials and inoculum more quickly and deeply, thereby accelerating the fermentation process and improving fermentation efficiency.

[0028] like Figure 2 As shown, the first drive assembly 7 includes a servo motor 71, a rotating shaft 72, and a connecting frame 73. The servo motor 71 is fixed to the top of the tank 1, the rotating shaft 72 is rotatably connected to the tank 1, and the connecting frame 73 is fixed to the top of the support plate 6. The upper end of the rotating shaft 72 is fixedly connected to the output shaft of the servo motor 71, and the lower end of the rotating shaft 72 is fixedly connected to the connecting frame 73. The servo motor 71 drives the rotating shaft 72 to rotate, which in turn drives the connecting frame 73 to rotate, thereby causing the support plate 6 to rotate, providing a foundation for subsequent stirring.

[0029] like Figure 2As shown, the stirring assembly 8 includes a stirring shaft 81 and multiple stirring rods 82. The upper end of the stirring shaft 81 passes through the support plate 6 and is rotatably connected to the support plate 6. The multiple stirring rods 82 are evenly fixed on the stirring shaft 81. When the stirring shaft 81 rotates, it drives the stirring rods 82 to rotate, thereby stirring and mixing the feed materials and bacteria in the tank 1.

[0030] like Figure 2 As shown, the second drive assembly 9 includes a dual-shaft motor 91, two first bevel gears 92, and two second bevel gears 92. The dual-shaft motor 91 is fixed to the top of the support plate 6. The two first bevel gears 92 are respectively fixed to the two output shafts of the dual-shaft motor 91. The second bevel gears 92 correspond one-to-one with the stirring shafts 81 of the two stirring assemblies 8. The first bevel gears 92 and the second bevel gears 92 mesh with each other. When the dual-shaft motor 91 is started, the two output shafts of the dual-shaft motor 91 will start to rotate simultaneously, thereby driving the first bevel gears 92 to rotate synchronously. When the first bevel gears 92 rotate, the power is transmitted to the second bevel gears 92 through the meshing action between the first bevel gears 92 and the second bevel gears 92, thereby driving the stirring shafts 81 to rotate. The rotation of the stirring shafts 81 causes the stirring assembly 8 to start working and stir the feed materials and bacteria in the tank 1.

[0031] like Figure 2 As shown, a first bearing 10 is provided at the connection between the rotating shaft 72 and the tank 1, and a second bearing 11 is provided at the connection between the stirring shaft 81 and the support plate 6. The first bearing 10 reduces the friction between the rotating shaft 72 and the tank 1, and the second bearing 11 reduces the friction between the stirring shaft 81 and the support plate 6, making the rotation of the rotating shaft 72 and the stirring shaft 81 smoother, reducing the wear of related parts, and extending the service life of the device.

[0032] like Figure 2 As shown, a support ring 12 is fixedly provided on the inner side of the lower end of the protective cylinder 5. Multiple balls 13 are movably embedded in the top of the support ring 12 in an annular shape at equal intervals. The balls 13 are rolledly connected to the bottom of the support disk 6. The arrangement of the balls 13 reduces the resistance that the support disk 6 needs to overcome when rotating, making the rotation more flexible and reducing the driving energy consumption.

[0033] like Figure 1 and Figure 2 As shown, the feed hopper 2 is equipped with a feed valve 14. When the feed valve 14 is closed, it can isolate the tank 1 from the outside air, dust and other impurities, so as to prevent bacteria or impurities from mixing into the fermentation raw materials and affecting the normal fermentation of microorganisms, thus ensuring normal fermentation and guaranteeing the fermentation quality.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
