Description

Technical Field

[0001] This utility model relates to the technical field of automatic flushing sight glass structure for fermentation tanks, specifically to a device for automatic flushing sight glass for fermentation. Background Technology

[0002] In the process of bio-fermentation (such as antibiotic production), the fermenter is one of the core pieces of equipment. In order to observe the fermentation status inside the fermenter in real time (such as cell growth, color change of fermentation liquid, foam height, etc.), a sight glass is usually installed on the fermenter body.

[0003] Currently, manual valve flushing of the sight glass is commonly used, requiring operators to climb to the top of the tank and use the antibiotic shut-off valve for flushing. This method is labor-intensive, inefficient, and poses safety risks associated with working at height. Frequent manual operation increases the probability of disrupting the sterile environment of the fermenter and introducing contaminants, directly affecting product quality and production safety. Contamination of the sight glass leads to unclear observation, making it impossible for operators to accurately and promptly grasp the situation inside the tank, which may delay the treatment and cause production losses.

[0004] Therefore, an automatic rinsing device for fermentation is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an automatic rinsing device for fermentation sight glasses. This solves the problem of the current common practice of manually rinsing sight glasses using valves, which requires operators to climb to the top of the tank and use an antibiotic shut-off valve for rinsing. This method is labor-intensive, inefficient, and poses safety risks due to working at height. Frequent manual operation increases the probability of disrupting the sterile environment of the fermenter and introducing contaminants, directly affecting product quality and production safety. Contaminated sight glasses also lead to unclear observation, preventing operators from accurately and promptly assessing the situation inside the tank, potentially delaying treatment and causing production losses.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1 - Figure 6This embodiment of an automatic rinsing sight glass device for fermentation includes a fermentation tank 1.

A rinsing mechanism is provided inside the fermentation tank 1. The rinsing mechanism includes a spray pipe 7, a nozzle 8, a pipe 9, a self-regulating angle valve 10, and a manual valve 11. The spray pipe 7 is fixedly connected inside the fermentation tank 1, the nozzle 8 is fixedly connected to one end of the spray pipe 7, the pipe 9 is fixedly connected to the other end of the spray pipe 7, the self-regulating angle valve 10 is fixed to the pipe 9, and the manual valve 11 is fixed to the pipe 9. A mounting base 13 is fixedly connected to the side, and a support plate 14 is fixedly connected to the top of the mounting base 13. A camera 15 is provided at one end of the support plate 14. An adjustment mechanism is provided at the connection between the support plate 14 and the camera 15. The mounting mechanism includes a flange 3, a groove 4, a lens 5, and a sealing ring 6. The flange 3 is located on the top of the connecting plate 2. The groove 4 is opened inside the flange 3 and the connecting plate 2. The lens 5 is located inside the groove 4. The sealing ring 6 is located inside the groove 4. The manual valve 11 is an antibiotic valve and is normally open. The pipeline 9 is connected to an external sterile water supply device.

[0020] Flange 3 is installed and fixed to connecting plate 2 with bolts, thereby fixing lens 5. After lens 5 is installed and fixed, the opening and closing of self-controlled angle valve 10 is controlled to allow sterile water inside pipe 9 to enter spray pipe 7. Spraying and washing the inner surface of lens 5 is done through nozzle 8. The nozzle 8 is set at an angle of 15 to 30 degrees with lens 5. When water is sprayed with the inclined spray hole on nozzle 8, a fan-shaped water curtain is formed, which can form a tangential scouring force to efficiently remove stains and avoid the spray pipe body from obstructing the observation field. The opening and closing gap of self-controlled angle valve 10 is controlled by an external timer control terminal, thereby achieving the effect of timed cleaning of lens 5, which makes it convenient for observers to observe the situation inside fermenter 1 through camera 15. The self-controlled angle valve 10 is connected to the controller, and the signal input terminal of the controller is connected to the upper-level DCS (distributed control system) to receive flushing commands from the DCS.

[0021] Please see Figure 1 - Figure 6 The spray pipe 7 has an L-shaped structure and is located at the bottom of the connecting plate 2. There are two sealing rings 6, and the lens 5 is tightly fitted to the inner wall of the groove 4 through the two sealing rings 6.

[0022] To facilitate adjustment of the camera 15, the adjustment mechanism includes a connecting seat 16, a toothed groove 17, a fixed shaft 18, a toothed ring 19, a slide 20, a through groove 21, a first fixed post 22, a second fixed post 23, and a plug plate 24. The connecting seat 16 is fixedly connected to the bottom of the camera 15. The toothed groove 17 is opened on one side of the connecting seat 16. The fixed shaft 18 is fixedly connected to one end of the support plate 14. The toothed ring 19 is slidably connected to the outside of the fixed shaft 18. The slide 20 is fixedly connected to one side of the toothed ring 19. The through groove 21 is opened on the top of the slide 20.

The plug plate 24 is slidably connected to the outside of the second fixed post 23.

[0023] After installing the camera 15, its illumination angle needs to be adjusted to ensure better observation of the inside of the fermentation tank 1. Simply pull the slide 20, and the toothed ring 19 will disengage from the toothed groove 17, thereby rotating the downward viewing angle of the camera 15 to ensure that it can illuminate the lens 5 and observe the inside of the fermentation tank 1 through the lens 5. Then, reset the slide 20, limit the angle of the camera 15 through the toothed ring 19, and then slide the insert plate 24 to engage with the first fixing post 22 to achieve a locking and fixing effect. The sliding slide 20 facilitates quick adjustment of the camera 15 angle, and the insert plate 24 enables quick locking.

[0024] Please see Figure 1 - Figure 6 The insert plate 24 is slidably engaged with the outside of the first fixed post 22, the connecting seat 16 is rotatably connected to the outside of the fixed shaft 18, the outer wall of the toothed ring 19 fits against the outer wall of the toothed groove 17, and the toothed ring 19 is slidably inserted into the inside of the toothed groove 17.

[0026] The spray pipe 7 can be arranged in a ring on the inner wall of the connecting plate 2, and the nozzle 8 is at an angle of 15 to 30 degrees to the bottom surface of the lens 5. When water is sprayed in conjunction with the inclined spray hole on the nozzle 8, a fan-shaped water curtain is formed. When cleaning the lens 5, it can form a tangential scouring force, effectively remove stains, and avoid the spray pipe body from obstructing the field of view.
