Description

Technical Field

[0001] The utility model relates to the technical field related to cleaning devices, in particular to an inner wall cleaning device for a fermentation tank. Background Art

[0002] A fermenter is an industrial device used for microbial fermentation. Its main body is typically a cylindrical stainless steel cylinder with a volume ranging from 1m to several hundred m. Design and processing require careful attention to a rigorous and rational structure. It should be able to withstand steam sterilization, offer operational flexibility, minimize internal attachments (avoiding dead corners), possess strong material and energy transfer capabilities, and be adjustable to facilitate cleaning and minimize contamination. It is suitable for the production of a variety of products and reduces energy consumption. Fermenters require thorough cleaning after each use to remove any residual microorganisms and sterilize thoroughly before reuse.

At the same time, many cleaning structures are difficult to penetrate into it, and its inner wall cannot be better cleaned.

[0004] However, the above patent still has the disadvantage that when cleaning the inside of the fermentation tank, water flow is used for cleaning. Since stubborn stains may adhere to the inside of the fermentation tank, scraping work is required. However, the scraping work cannot be automatically adjusted according to the internal size of the fermentation tank, resulting in poor cleaning effect due to loose fit, further reducing the practicality of the cleaning device.

[0005] For this reason, we propose a fermentation tank inner wall cleaning device. Utility Model Content

[0012] Furthermore, the top of the movable seat is fixedly connected to a limit rod, and the limit rod slides on the side wall of the mounting beam.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 3The utility model provides a technical solution: a fermentation tank inner wall cleaning device, comprising a mounting crossbeam 1, a threaded rod 2 is threadedly connected to the side wall of the mounting crossbeam 1, the end of the threaded rod 2 is rotatably connected to a movable seat 3 through a bearing, the top of the movable seat 3 is fixedly connected to a driving mechanism 4, the end of the driving mechanism 4 is connected to a rotating cylinder 5, and the two sides of the rotating cylinder 5 are connected to a cleaning mechanism 6; wherein the cleaning mechanism 6 includes a hollow rod 61 connected to the side wall of the rotating cylinder 5, and an adjusting rod 62 is slidably connected to the inside of the hollow rod 61. The two ends of the section rod 62 are respectively fixedly connected with a scraper 63 and a sealing ring 64. The sealing ring 64 slides tightly inside the hollow rod 61. By sliding the adjusting rod 62 inside the hollow rod 61, the scraper 63 can be installed inside the fermentation tank, so that it can be adjusted according to the internal size of the fermentation tank. The scraper 63 can fit tightly to the inner wall of the fermentation tank for cleaning and scraping. Under the setting of the sealing ring 64, the sealing between the hollow rod 61 and the adjusting rod 62 can be guaranteed, thereby ensuring that no leakage problems will occur during the later water injection.

[0023] The scraper 63 is provided with water spraying holes on its surface to facilitate the subsequent water spraying work.

[0024] according to Figure 3 It can be seen that the inner wall of the mounting beam 1 is rotatably connected to a bidirectional screw rod 7 through a bearing. Both ends of the bidirectional screw rod 7 pass through the mounting beam 1 and are fixedly connected to a handle extending outside. The surface of the bidirectional screw rod 7 is threadedly connected to a movable clamp 8. The inner wall of the mounting beam 1 is fixedly connected to a guide rod 9. The movable clamp 8 slides on the surface of the mounting beam 1. Through the rotation of the bidirectional screw rod 7, the spacing of the movable clamp 8 can be adjusted. When the spacing of the movable clamp 8 is adjusted, it can be clamped and fixed according to different fermentation tank sizes, thereby ensuring the stability of the cleaning device during use. And under the setting of the guide rod 9, it can play a guiding and limiting role for the movable clamp 8 when it moves.

[0025] according to Figure 2 It can be seen that the driving mechanism 4 includes a hollow rotating shaft 41 that rotates on the top of the movable seat 3 through a bearing, and the bottom of the hollow rotating shaft 41 is fixedly connected to the rotating cylinder 5. Through the setting of the hollow rotating shaft 41, the rotating cylinder 5 can be rotated. At the same time, the hollow rotating shaft 41 is hollow, so that it can be connected to an external water pipe, so that water can be injected into the rotating cylinder 5 and the cleaning mechanism 6, so that the cleaning effect can be better when spraying water during cleaning.

[0026] according to Figure 2It can be seen that the driving mechanism 4 also includes a driving motor 42 fixed on the top of the movable seat 3, and the output end of the driving motor 42 is fixedly connected to the main gear 43, and the surface of the main gear 43 is meshed with a slave gear 44, and the slave gear 44 is fixed on the hollow rotating shaft 41. Driven by the driving motor 42, it can drive the main gear 43 to rotate, and the main gear 43 can drive the surface meshed slave gear 44 to rotate. Since the slave gear 44 is fixed on the hollow rotating shaft 41, it can rotate synchronously with the rotating cylinder 5, and when the rotating cylinder 5 rotates, it can perform circular rotation cleaning along the inside of the fermentation tank.

[0027] according to Figure 2 It can be seen that a return spring 65 is sleeved on the surface of the adjusting rod 62, and the two ends of the return spring 65 are respectively fixedly connected to the hollow rod 61 and the sealing ring 64. Under the action of the rebound force of the return spring 65, the sealing ring 64 can be reset, thereby pushing the sealing ring 64 fixed on the hollow rod 61 to extend outward, so that it fits tightly inside the fermentation tank.

[0028] according to Figure 1 It can be seen that the top of the movable seat 3 is fixedly connected to the limit rod 10, and the limit rod 10 slides on the side wall of the mounting beam 1. Through the setting of the limit rod 10, it can play a guiding and limiting role in the lifting of the movable seat 3.

[0029] The working principle of the present utility model is as follows: when in use, the mounting crossbeam 1 is first mounted on the top of the fermentation tank, and then the threaded rod 2 is rotated so that the movable seat 3 can be moved downward, so that the cleaning mechanism 6 fixed on the surface of the rotating cylinder 5 is located on the top of the fermentation tank. At this time, the cleaning mechanism 6 is manually retracted and installed inside the fermentation tank. When the cleaning mechanism 6 is installed inside the fermentation tank, it is then driven by the driving mechanism 4 so that the rotating cylinder 5 can drive the cleaning mechanism 6 to rotate, thereby performing circumferential cleaning and scraping work on the inside of the fermentation tank. When the threaded rod 2 is adjusted downward, it can rotate slowly downward to clean and scrape the inside of the fermentation tank.
