[0002] A fermentation tank, also known as a fermentation tank device or fermenter, is a container used for microbial fermentation reactions. It is widely used in the food, beverage, pharmaceutical, and chemical industries. It is mainly used to cultivate microorganisms, enzymes, or other biological reaction processes in culture media and raw materials, thereby promoting chemical or biological reactions. Beer fermentation requires specific conditions such as temperature, pH, dissolved oxygen, and carbon dioxide concentration, thus necessitating the use of fermentation tanks for beer fermentation.

[0003] Beer fermentation tanks can be categorized into several types, including open fermentation tanks, closed fermentation tanks, and single-stage fermentation tanks. Each type has its own characteristics and applicable scenarios. Traditional fermentation tanks are typically used for small-batch production, while modern pressure fermentation tanks, cryogenic fermentation tanks, and double-layer fermentation tanks are used for large-scale production and higher-quality beer brewing. Closed fermentation tanks, in particular, prevent contact between the tank interior and outside air during fermentation, avoiding the influence of oxygen and pollutants from the outside air. Closed fermentation tanks are widely used fermentation containers in the modern beer industry.

[0004] However, existing technologies still present some inconveniences when cleaning fermenters. Traditional fermenter cleaning methods require operators to enter the tank through the cleaning port, which is cumbersome and inefficient. Especially in production environments requiring frequent cleaning and maintenance, traditional cleaning methods are not only time-consuming but also prone to human error or incomplete cleaning. Therefore, simplifying the fermenter cleaning process, improving cleaning efficiency, and ensuring that the scraper better adheres to the inner wall of the tank have become urgent problems to be solved. Utility Model Content

[0029] 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.

[0030] Reference Figures 1-3This utility model provides an embodiment of a beer fermentation tank, comprising a tank body 1. A liquid outlet pipe 2 is fixedly connected to the outer wall of the tank body 1, used to discharge fermentation liquid or waste liquid, ensuring that the liquid inside the tank body 1 can be smoothly discharged. A drive assembly is provided at the top of the tank body 1, providing power to drive a rotating shaft 4 inside the tank body 1 to rotate, thereby driving related components to work. The rotating shaft 4 is rotatably connected inside the tank body 1, supporting and driving the movement of a water injection assembly and a scraper 14, ensuring effective cleaning of the internal surface of the fermentation tank. A water injection assembly is provided on the outer wall of the rotating shaft 4, used to clean the inner wall of the tank body 1 by providing water or cleaning liquid. A bracket 7 is fixedly connected to the outer wall of the rotating shaft 4, supporting the scraper 14 and allowing it to clean the inner wall of the tank body 1 under the drive of the rotating shaft 4. The scraper 14 is provided inside the bracket 7, used to scrape off deposits or residues on the inner wall of the fermentation tank, ensuring a cleaning effect.

[0031] The water injection assembly includes a sleeve 5, the bottom of which is fixedly connected to the top of the tank 1. The sleeve 5 serves as the support for the water injection assembly, ensuring its stable operation. A rotating shaft 4 passes through the sleeve 5 and rotates within it, driving the water injection assembly to complete its work. A sealing assembly is installed inside the sleeve 5 to ensure no leakage occurs at the connection between the water injection assembly and the rotating shaft 4, preventing cleaning water from leaking from the connection point and affecting the cleaning effect. An inlet pipe 6 is fixedly connected to the outer wall of the sleeve 5, connecting to an external water source to provide cleaning fluid or water to the water injection assembly. A cavity 10 is formed inside the rotating shaft 4, which receives and guides water flow into the shaft and delivers cleaning fluid to the nozzle 9 via a cleaning pipe 8. A cleaning pipe 8 is fixedly connected to the outer wall of the rotating shaft 4, guiding the water flow or cleaning fluid to the nozzle 9, ensuring the water flow is evenly sprayed onto the inner wall of the tank 1 for cleaning. A nozzle 9 is fixedly connected to the outer wall of the cleaning pipe 8. The nozzle 9 is used to evenly spray the cleaning liquid onto the inner wall of the fermentation tank, forming a spray covering the cleaning area. The drive assembly includes a motor 3, which provides rotational power to drive the rotating shaft 4 to rotate, realizing the mechanical action during the cleaning process. The outer wall of the motor 3 is fixedly connected to the top of the tank body 1, and the fixed position of the motor 3 ensures that the motor 3 can stably drive the rotating shaft 4. The output end of the motor 3 is connected to one end of the rotating shaft 4. The rotation of the motor 3 drives the rotating shaft 4 to rotate, thereby driving the water injection assembly and scraper 14 to perform cleaning work. The sealing assembly includes a sealing ring 11, which is used to ensure that no water leakage occurs at the connection between the rotating shaft 4 and the sleeve 5, ensuring that the cleaning water can be smoothly conducted to the required position and preventing the cleaning liquid from leaking out. The outer wall of the sealing ring 11 is fixedly connected to the inside of the sleeve 5, and the inner wall of the sealing ring 11 is attached to the outer wall of the rotating shaft 4, effectively preventing the leakage of cleaning water and ensuring the efficiency of the cleaning operation and the long-term stable operation of the equipment.

[0032] Specifically, during the cleaning of the inside of tank 1, cleaning water flows smoothly into sleeve 5 through inlet pipe 6. Sleeve 5 provides a stable channel for guiding the cleaning water, which then enters the rotating shaft 4 through cavity 10, effectively transferring it to the area of ​​rotating shaft 4. The cleaning water is sprayed evenly and precisely onto the inner wall surface of tank 1 through nozzles 9 on cleaning pipe 8, ensuring thorough cleaning of every part. Simultaneously, the output of motor 3 drives rotating shaft 4 to rotate. Rotating shaft 4 and sleeve 5 are tightly sealed by sealing ring 11 to prevent cleaning water leakage to the outside, ensuring the efficiency and safety of the cleaning process. Support 7, through precise structural design, drives scraper 14 to clean the inner wall of tank 1. Scraper 14 slides flexibly along the inner wall of tank 1, thoroughly removing residue and dirt.

[0033] Reference Figure 3 and Figure 4 The bracket 7 has a fixed block 12 inside, which stabilizes other components inside the bracket 7 and ensures that the scraper 14 and other adjustment devices maintain a stable position during cleaning. The fixed block 12 has a threaded hole 16 inside, providing a fixed connection position for the mounting bolt 17, ensuring that the bolt 17 can be firmly fixed in the appropriate position, guaranteeing the stability and adjustment function of the scraper 14. A connecting plate 13 is fixedly connected to the outer wall of the scraper 14, which connects to the bracket 7 and other related components, allowing the scraper 14 to perform cleaning work on the inner wall of the tank 1 via the bracket 7. The connecting plate 13 has an adjustment groove 15 inside, which adjusts the position of the scraper 14, allowing it to adjust the contact angle and pressure with the inner wall of the tank 1 according to actual needs, thereby achieving more precise cleaning. The fixed block 12 has a bolt 17 inside, which adjusts the position of the scraper 14 and is fixedly connected inside the fixed block 12, serving to secure the connection between the scraper 14 and the bracket 7. Bolt 17 is threaded into threaded hole 16. By rotating bolt 17, the operator can adjust the position of scraper 14 according to actual needs, adapting it to different cleaning requirements and ensuring optimal cleaning results each time. A washer 18 is slidably connected to the outer wall of bolt 17. The washer 18 serves to buffer and prevent wear on bolt 17, reducing friction and ensuring smoother adjustment. The bottom of washer 18 fits against the outer wall of connecting plate 13. The clamping action of washer 18 stabilizes the contact surface between bolt 17 and connecting plate 13, enhancing the stability of the adjustment process and preventing loosening or instability during adjustment.

[0034] Specifically, when adjusting the distance between the scraper 14 and the tank 1, first loosen the bolt 17. The bolt 17 passes through the adjusting groove 15 on the connecting plate 13, allowing the scraper 14 to slide smoothly along the outer wall of the bolt 17 within the adjusting groove 15. Through this sliding method, the operator can precisely adjust the distance between the scraper 14 and the tank 1, ensuring a tight and uniform fit between the scraper 14 and the inner wall of the tank 1, achieving optimal cleaning results. Once the distance is adjusted to the ideal position, the operator simply needs to retighten the bolt 17 to ensure the scraper 14 is fixed in the set position. To prevent the bolt 17 from loosening due to vibration or other factors during use, a washer 18 is provided on the outside of the bolt 17. The washer 18 effectively prevents the bolt 17 from loosening, thereby maintaining the stability and adjustment accuracy of the scraper 14. Adjusting the angle and distance of the scraper 14 becomes more convenient and reliable, ensuring efficient and long-lasting cleaning results.

[0035] Working principle: When using this beer fermentation tank, the cleaning water first enters the sleeve 5 through the inlet pipe 6 to clean the inside of the tank 1. Then, the cleaning water enters the rotating shaft 4 through the cavity 10. The cleaning water is then sprayed onto the inner wall of the tank 1 through the nozzle 9 on the cleaning pipe 8. Then, the output end of the motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 and the sleeve 5 are sealed by the sealing ring 11 to prevent the cleaning water from leaking. Then, the bracket 7 drives the scraper 14 to clean the inside of the tank 1, which achieves the effect of facilitating the cleaning of the inside.

[0036] In addition, when adjusting the distance between the scraper 14 and the tank 1, first loosen the bolt 17, then the scraper 14 slides on the outer wall of the bolt 17 through the adjustment groove 15 on the connecting plate 13, thereby adjusting the distance between the scraper 14 and the tank 1. After the adjustment is in place, tighten the bolt 17. The bolt 17 is prevented from loosening by the washer 18, which achieves the effect of facilitating the adjustment of the angle of the scraper 14.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
