Description

Technical Field

[0001] The utility model relates to the field of fermentation facilities, in particular to a middle and upper layer supplementary aeration mechanism and a fermentation tank. Background Art

[0002] Fermentation typically takes place within a fermentation tank / tank. During fermentation processes requiring an aerobic environment, sufficient gas must be replenished to meet fermentation requirements and ensure efficient and thorough fermentation. Currently, a common approach involves installing aeration systems at the bottom of the fermentation tank, such as tubular aeration pipes and disc aeration heads, to aerate the material at the bottom of the tank. However, due to the deep material piles in the fermentation tank, the material at the bottom is often compacted, resulting in reduced voids and making it difficult for aeration to penetrate sufficiently high. Consequently, the material in the middle and upper portions of the tank cannot receive sufficient aeration, resulting in insufficient aeration in these areas, creating a localized anaerobic environment that affects fermentation.

[0024] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0025] Example 2: A fermentation tank

[0026] This fermentation tank is equipped with the aeration mechanism of Example 1. The fermentation tank adopts a waterproof concrete trough structure, which is no different from existing fermentation tanks, and is generally square or rectangular. A groove 18 is provided on the side wall of the fermentation tank. The groove 18 includes a vertical groove and a horizontal groove. The horizontal groove corresponds to the height and position of the aeration pipe 16. The bottom end of the vertical groove is connected to one end of the horizontal groove. The top end of the vertical groove extends through the top side of the fermentation tank. The air pipe 5 is fixed in the vertical groove. The mounting plate 1 is fixed to the bottom end of the vertical groove. The aeration pipe 16 can be retracted into the horizontal groove. When the upper supplementary aeration is not in use, the aeration pipe 16 can be completely stored in the horizontal groove, and the entire aeration mechanism does not occupy space in the fermentation tank.

[0027] The horizontal trough in this example is installed at the upper part of the fermentation tank, mainly used to supplement the aeration of the material in the upper layer (below the surface layer). It is also easy to install and maintain.

[0028] Example 3: An aeration device

[0029] Compared with Example 1, this example differs in that aeration holes are provided on the upper and lower sides of the aeration pipe 16, and the air pipe 5 is connected to the air source with a hose. The following structures are also added:

[0030] It also includes a slide bar 13 and a slider 14, the slide bar 13 is vertically arranged, the slider 14 is slidably connected to the slide bar 13, the slider 14 is fixed to one side of the protection box 12 (away from the motor 10), and a support frame 15 is fixed to the bottom of the slide bar 13. The support frames 15 are two and are respectively arranged on both sides of the mounting pipe 2, and the support frames 15 are located within the projection range below the protection box 12. The spacing between the two support frames 15 is greater than the width of the aeration pipe 16 and the rotary joint 6. When the protection box 12 falls along the slide bar 13, it can pass between the two support frames 15 and let the bottom surface of the protection box 12 fall on the two support frames. The protective box 12 is supported on a support frame 15. Based on the above structure, a pull ring 17 is provided above the protective box 12, and a pull rope is connected to the pull ring 17. The protective box 12 and the aeration components such as the mounting pipe 2, gear 9, motor 10, aeration pipe 16, rotary joint 6 installed inside and outside the protective box 12 can be conveniently lifted upward and directly removed from the slide bar 13 for maintenance, such as unblocking or replacing the aeration pipe 16. Therefore, the device can be installed in the middle of the fermentation tank, which can not only realize the aeration supplement of the upper and lower areas in the middle of the material, but also solve the problem of difficult maintenance in the middle of the tank wall.

[0031] Based on the above structure, the support frame 15 and the slide bar 13 can be connected by bolts, which can achieve quick disassembly and facilitate adjustment of the height of the support frame 15, thereby adjusting the position of the aeration pipe 16 for supplementary aeration.

[0032] The present invention is not limited to this example, and a power structure may be added to realize automatic control of the lifting and lowering of the aeration pipe 16 and dynamic adjustment of the aeration position.

[0033] Example 4: A fermentation tank

[0034] The fermentation tank is a rectangular trough. Supplementary aeration of the upper and middle portions of the material is achieved primarily by adding the aeration mechanism of Example 3 to the fermentation tank. A groove 18 is provided on the wall of the fermentation tank corresponding to the location where the aeration mechanism is installed. This groove 18 provides space for installing the aeration mechanism and facilitates maintenance and use.

[0035] The groove 18 is rectangular, and its upper side passes through the top side of the fermentation tank wall and has a top side notch. The groove 18 has an inner wall notch in the fermentation tank. The slide bar 13 is fixed on the vertical groove wall on one side of the groove 18. Based on the structure of the groove 18, the height of the aeration pipe 16 can be conveniently adjusted, or the protection box 12 and the aeration pipe 16 can be raised for maintenance and replacement.

[0036] A baffle 19 is provided on the inner wall notch, and both sides of the baffle 19 are fixed to the groove walls on both sides of the inner wall notch by bolts. The top side of the baffle 19 is at the same height as the fermentation groove, and the bottom side of the baffle 19 is located above the aeration pipe 16 (when the protection box 12 falls on the support frame 15). The gap is used to facilitate the aeration pipe 16 to swing out of the groove 18 to achieve aeration supplement operation.
