Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and in particular to a carbon source fermentation tank. Background Technology

[0002] Carbon source fermentation tanks are used to convert raw materials into high-quality carbon source products through the fermentation of microorganisms. They have wide applications in ecological environment improvement, such as aquaculture and sewage treatment.

[0003] During the fermentation process in the carbon source fermentation tank, the raw materials are mixed and fermented by stirring. When the raw materials are stirred, some of them will stick to the inner wall of the fermentation tank, making it difficult to mix with the raw materials inside the fermentation tank and difficult to clean. Existing stirring mechanisms have uneven mixing and low mixing efficiency because the stirring blades on the stirring shaft mostly rotate in the same direction. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a carbon source fermentation tank that can scrape off the fermentation material adhering to the inner wall of the fermentation tank during the stirring process, so that it can be fully mixed into the fermentation tank and improve the mixing efficiency.

[0005] The technical solution of this utility model is as follows: It includes a cylinder, a discharge pipe at the bottom of the cylinder, a rotating drum driven by a motor inside the cylinder, crossbars fixedly connected to the upper and lower parts of the left and right side walls of the rotating drum, and scrapers connected between the free ends of the two crossbars on the same side, with the scrapers sliding in contact with the inner wall of the cylinder; the rotating drum is provided with multiple stirring mechanisms, and a round rod is provided inside the rotating drum, one end of which is rotatably connected to the top surface of the rotating drum, and the other end of which movably passes through the rotating drum and is fixedly connected to the bottom of the cylinder; each stirring mechanism includes a bevel gear and two rotating rods, the bevel gear being larger at the top and smaller at the bottom, and is fitted and fixed on the round rod inside the rotating drum, the two rotating rods being opposite each other and movably passing through the rotating drum, and bevel gears meshing with the bevel gears being fixedly connected to the opposite ends of the two rotating rods, and multiple sets of stirring rods spaced apart on each of the two rotating rods.

[0006] This invention has a simple structure and can achieve multiple stirring effects, greatly improving mixing efficiency;

[0007] While the rotating drum of this invention is rotating, the crossbar can also drive the scraper to rotate, so that the scraper can scrape off the fermentation material adhering to the drum body, avoiding waste of raw materials and achieving a high utilization rate of raw materials. It can also eliminate the need for cleaning the inner wall after fermentation, thus improving work efficiency. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0013] like Figures 1-3 As shown, a carbon source fermentation tank includes a cylindrical body 1, which is a hollow cylinder with an open top. The top surface of the cylindrical body 1 is sealed by a cover plate 11, and the cover plate 11 is provided with a feed door 12. A discharge pipe 13 is provided on the lower side wall of the cylindrical body 1. A rotating drum 3 driven by a motor 2 is provided inside the cylindrical body 1. The lower opening of the rotating drum is sealed by a bottom plate 14. Crossbars 7 are fixedly connected to the upper and lower parts of the left and right side walls of the rotating drum 3, respectively. The crossbars 7 are round rods. Scrapers 8 are connected between the free ends of the two crossbars on the same side. The scrapers 8 slide in contact with the inner wall of the cylindrical body 1. Multiple stirring rods are provided on the rotating drum 3 along the height direction. The mixing mechanism 1 has a circular rod 4 inside the rotating drum 3. One end of the circular rod 4 is rotatably connected to the top surface inside the rotating drum 3, and the other end is movably connected through the rotating drum 3 and fixedly connected to the bottom of the drum body 1. Each mixing mechanism 1 includes a bevel gear 5 and two rotating rods 9. The bevel gear 5 is larger at the top and smaller at the bottom, and is sleeved and fixed on the circular rod 4 inside the rotating drum. The two rotating rods 9 are opposite each other and movably connected through the rotating drum 3. The opposite ends of the two rotating rods 9 are fixedly connected to bevel gears 6 that mesh with bevel gears 5. Each of the two rotating rods 9 has multiple sets of mixing rods 1 spaced apart along the length direction of the rotating rod 9.

[0014] The two rotating rods 9 on the same stirring mechanism are rotatably connected to the scrapers 8 on both sides at opposite ends.

[0015] A second stirring mechanism is provided between every two stirring mechanisms 1. The second stirring mechanism includes a bevel gear 3 15 and two rotating rods 2 17. The bevel gear 3 15 is smaller at the top and larger at the bottom, and is sleeved and fixed on a round rod 4 inside the rotating drum. The bevel gear 3 15 is located between two bevel gears 1 5. The two rotating rods 2 17 are opposite each other and move through the rotating drum 3. The opposite ends of the two rotating rods 2 17 are fixedly connected to bevel gears 4 16 that mesh with bevel gears 3 15. Both rotating rods 2 17 have multiple sets of stirring rods 2 that are spaced apart from each other along the length direction of the rotating rod 2.

[0016] The two rotating rods 17 on the same stirring mechanism 2 are rotatably connected to the scrapers 8 on both sides at opposite ends.

[0017] The multiple stirring rods 18 on each set of stirring rods 2 are arranged in a ring array along the rotating rod 2 17; the multiple stirring rods 10 on each set of stirring rods 1 are arranged in a ring array along the rotating rod 1 9; the multiple sets of stirring rods 1 on the rotating rod 1 9 on the same side are staggered with the multiple sets of stirring rods 2 on the rotating rod 2 17, the distance from the rotating rod 2 17 to the upper and lower rotating rods 1 9 are equal, and the length of stirring rod 10 is greater than half the distance between the rotating rod 2 17 and any rotating rod 1 9.

[0018] The motor 2 is fixedly connected to the top surface of the cover plate 11, and the output shaft of the motor 2 moves through the cover plate 11.

[0019] The scraper 8 is triangular prism-shaped, with its flat end fixedly connected to the free end of the crossbar 7, and its tip sliding in contact with the inner wall of the cylinder 1.

[0020] In use, raw materials are fed in through the feed gate 12, and then the motor 2 is started. The motor 2 drives the rotating drum 3 to rotate. When the rotating drum 3 rotates, it drives the rotating rod 1 9 to rotate around the round rod 4. When the rotating rod 1 9 rotates around the round rod 4, the two bevel gears 2 6 rotate around the bevel gear 5 under the drive of the two rotating rods 1 9. Through the meshing of the bevel gears 1 5 and 2 6, the rotating rod 1 9 can rotate along its own central axis while rotating around the round rod 4, and the stirring rod 1 1 stirs the raw materials. When the rotating rod 2 17 rotates around the round rod 4, the two bevel gears 4 16 rotate around the round rod 4. Driven by rod 2 17, it rotates around bevel gear 3 15. Through the meshing of bevel gear 3 15 and bevel gear 4 16, rod 2 17 can rotate in the opposite direction to rod 1 along its own central axis while rotating around rod 4. Stirring rod 2 stirs the raw materials in the opposite direction, making the raw materials more thoroughly mixed and shortening the stirring time. When the drum 3 rotates, it can also drive scraper 8 through the crossbar 7 connected to the side wall. During the rotation, scraper 8 can scrape off the fermented material adhering to the inner wall of the drum 1 and mix the fermented material into the fermentation tank, improving the stirring efficiency and making the raw materials more evenly mixed.

[0021] This invention uses a motor to drive a rotating drum, which in turn causes stirring mechanism one and stirring mechanism two to rotate around a circular rod. Then, through the action of bevel gear one and bevel gear three set on the circular rod, rotating rod one and rotating rod two rotate on their own axis while rotating, thereby achieving a multi-stage stirring effect.
