Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation tank technology, and more specifically, it relates to a fermentation tank for fermenting biological feed. Background Technology
[0002] In the current technology, although the biological feed fermentation tank is equipped with a certain stirring device during operation, the stirring process often fails to achieve sufficient mixing of the fermentation raw materials in some cases. Insufficient mixing of raw materials may lead to local areas being too acidic or hypoxic, affecting the activity of microorganisms and thus affecting the fermentation effect.
[0003] In the process of bio-fermentation, existing fermentation tanks often lack effective heat dissipation or heat distribution management methods. However, they have not fully considered the heat dissipation and stirring process for high temperature accumulation. Due to the lack of timely heat dissipation, stirring or turning process, the heat inside the fermentation tank cannot be released in time, and the temperature in some areas is too high, which leads to the death of microorganisms or over-fermentation, resulting in uneven fermentation.
[0004] In the process of biological feed fermentation, the particle size of the raw materials has a significant impact on the fermentation effect. Larger raw material particles not only hinder the contact and decomposition of microorganisms, but also affect the uniform distribution of oxygen and nutrients, further reducing fermentation efficiency. Existing fermentation tanks generally lack effective crushing devices, resulting in feed raw materials not being sufficiently crushed before entering the fermentation tank. Utility Model Content

[0034] A discharge pipe 13 is installed on the mixing drum 3, and a valve 14 is installed on the discharge pipe 13. A heater is installed inside the mixing drum 3.
[0035] The threaded rod 9 is threadedly connected to a scraper plate 15, which has holes 16 evenly spaced on it. The scraper plate 15 is slidably connected to the heat sink frame 7.
[0036] A shielding cover 17 is rotatably connected to one end of the heat sink frame 7, and a bolt 18 is detachably installed between the shielding cover 17 and the heat sink frame 7.
[0037] In this embodiment, during use, after the feed is injected into the mixing drum 3, the second motor 4 is started, causing the rotating rod 5 at its output end to rotate. During rotation, the rotating blade 6 and the agitator plate 10 on the motor drive the rotating rod 5 to fully mix the feed. Furthermore, a heater installed inside the mixing drum 3 is used to promote the fermentation process of the feed. After the mixing process is completed, the valve 14 is opened to discharge the feed from the discharge pipe 13, allowing it to exit along the discharge plate 12. The feed is fed into the heat dissipation frame 7. Then, through continuous forward and reverse driving, the first motor 8 drives the threaded rod 9 at the output end to rotate, which in turn drives the scraper 15 on it to slide along the heat dissipation frame 7. During the sliding movement, the scraper 15 works with the holes 16 on it to allow the feed to flow through continuously, thereby continuously agitating and dissipating the feed. After the operation is completed, the bolt 18 is removed along the cover 17, and the cover 17 is rotated and opened along the heat dissipation frame 7, so that the feed can be discharged.

During the rotation, the spiral blade 26 rotates, continuously conveying the feed and discharging it from the discharge port 28 at one end of the crushing cylinder 21. During the rotation of the conveying rod 25, the rotating blade 27 on it rotates, thereby completing the crushing process of the feed and discharging it from the discharge plate 24. The feed is then discharged into the feed inlet 11 on the mixing cylinder 3.
[0042] In summary, during the use or operation of the overall equipment: After the feed is injected into the mixing drum 3, the second motor 4 is started, causing the rotating rod 5 at the output end to rotate. During rotation, the rotating blades 6 and the agitator plates 10 on the rod drive the rotating rod to fully mix the feed. Furthermore, the heater inside the mixing drum 3 is used in conjunction with the equipment to promote the fermentation process of the feed. After the mixing process is completed, the valve 14 is opened to discharge the feed from the discharge pipe 13, allowing it to flow along the discharge plate... Feed 12 is discharged into the heat dissipation frame 7. Then, through continuous forward and reverse driving, the first motor 8 drives the threaded rod 9 at the output end to rotate, which drives the scraper 15 on it to slide along the heat dissipation frame 7. During its sliding movement, it cooperates with the holes 16 on the scraper 15 to allow the feed to flow through continuously, thereby continuously agitating and dissipating the feed. After the operation is completed, the bolt 18 is removed along the cover 17, so that the cover 17 can be rotated and opened along the heat dissipation frame 7, thereby allowing the feed to be discharged.
[0043] During use, feed is injected into the feed hopper 23 on the crushing cylinder 21. The third motor 20 on the mounting frame 19 is started, which drives the drive assembly 22 at the output end, thereby driving the conveying rod 25 to rotate. During the rotation, the spiral blade 26 rotates, continuously conveying the feed and discharging it from the discharge port 28 at one end of the crushing cylinder 21. During the rotation of the conveying rod 25, the rotating blade 27 on it rotates, thereby completing the crushing process of the feed and discharging it from the discharge plate 24.
