[0002] In modern industrial production and scientific research, fermenters are a key piece of equipment widely used in food, chemical, biotechnology and other fields. Their core function is to provide a suitable environment to promote the growth and metabolism of microorganisms, thereby achieving the fermentation production of specific products.

[0003] A search revealed Chinese Patent Publication No. CN221192116U, which discloses a fermentation tank with good sealing performance. The tank includes a tank body, with a limiting ring fixedly connected to the inner side of the tank body. A first sealing ring is fixedly connected to the top of the limiting ring, and a second sealing ring is movably connected to the top of the first sealing ring. The outer sides of the first and second sealing rings press against each other. A protective cover is fixedly connected to the top of the second sealing ring. Multiple connecting cylinders are fixedly connected to the outer side of the fermentation tank body. A connecting block is fixedly connected to the top of the output shaft of each connecting cylinder, and a connecting frame is fixedly connected to the top of the connecting block. Multiple connecting components are fixedly connected to the bottom of the protective cover. This fermentation tank with good sealing performance provides a more secure seal between the cap and the filling port, effectively preventing alcohol evaporation and improving the taste and quality of the finished wine.

[0004] While the aforementioned technologies improve the sealing performance of the fermenter body, multiple connecting rods need to be rotated when installing or removing the tank cover. Furthermore, the hinged connecting rods cause the mounting block to re-clamp into the connecting frame due to gravity, making installation and disassembly inconvenient and reducing the ease of use of the fermenter. Therefore, a fermenter with good sealing performance is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fermenter with good sealing performance, aiming to improve the problem in the prior art that "when installing and disassembling the tank lid, multiple operations are required and the installation block is easily reset and stuck in the connecting frame, making installation and disassembly inconvenient".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fermenter with good sealing performance, comprising a tank body, a tank cover at the top of the tank body, a cylinder fixedly installed on the outer wall of the tank body, a guide block fixedly connected to the top of the output shaft of the cylinder, a tensioning assembly between the tank body and the tank cover, the tensioning assembly comprising a fixing block, the fixing block being fixedly connected to the bottom of the tank cover, a ring slidably connected to the outer wall of the tank body, a groove being formed at the bottom of the fixing block, a slider being slidably connected to the inner wall of the groove, one end of a spring being fixedly connected to the rear surface of the slider, the other end of the spring being fixedly connected to the inner wall of the fixing block, a locking block one being fixedly connected to the bottom of the slider, a locking block two being fixedly connected to the top of the guide block, the bottom of the locking block one engaging with the inner wall of the locking block two, and an elliptical block being fixedly connected to the rear surface of the locking block one.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting a fixing block, a locking block one, and a spring in cooperation, after the bottom of the locking block one is locked into the locking block two, the fixing block can be driven by the guide block to tighten the adhesion between the can lid and the can body, thereby increasing the sealing performance.

[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 Figure 1 - Figure 3This utility model provides an embodiment of a fermenter with good sealing performance, including a tank body 1, which is the main body of the fermenter. The top of the tank body 1 is provided with a lid 2 for sealing the top of the tank body 1, forming a sealed space together with the tank body 1 to prevent external impurities and microorganisms from entering and maintain a stable fermentation environment. A cylinder 5 is fixedly installed on the outer wall of the tank body 1 to provide power. The extension and retraction of the output shaft drives the guide block 4 to move up and down, thereby realizing the operation of tightening or loosening the lid 2 and the tank body 1, controlling the degree of fit between the two, and indirectly affecting the sealing performance of the fermenter. The top of the output shaft of the cylinder 5 is fixedly connected to the output shaft of the cylinder 5 and moves under the drive of the cylinder 5. The second locking block 39 at the top of the cylinder 5 cooperates with the first locking block 31 on the fixed block 3 to transmit the force of the cylinder 5, tighten the lid 2 and the tank body 1, ensure that the two fit tightly, and enhance the sealing performance of the guide block 4.

[0031] Furthermore, a tensioning assembly is provided between the tank body 1 and the can lid 2. The tensioning assembly includes a fixed block 3 that provides support. The fixed block 3 is fixedly connected to the bottom end of the can lid 2. An extrusion elliptical block 32 is slidably connected to the outer wall of the tank body 1, which drives the locking block 31 to move outward, releasing the restriction on the can lid 2 and facilitating the opening of the ring 38 of the can lid 2. When the ring 38 is moved downward, the limiting block 61 can be inserted into the limiting groove 6 to limit the can lid 2, thereby improving the installation stability and sealing. The bottom end of the fixed block 3 is provided with a sliding track for the slider 34, allowing the slider 34 to move smoothly within the fixed block 3, ensuring the normal extension and retraction of the locking block 31, and thus realizing the connection and separation operation between the can lid 2 and the tank body 1. The inner wall of the sliding groove 35 is slidably connected to the slider 34 that supports the locking block 31.

[0032] Furthermore, one end of a spring 33 is fixedly connected to the rear surface of the slider 34, and the other end of the spring 33 is fixedly connected to the inner wall of the fixed block 3. After the spring 33 is squeezed and stretched, the reverse force of the stretched spring can make the locking block 31 quickly reset. The bottom end of the slider 34 is fixedly connected to the locking block 31, which can be engaged with the guide block 4 to tighten. The bottom end of the rear surface of the locking block 31 is set as an inclined surface. The top end of the guide block 4 is fixedly connected to the locking block 2, which pulls the locking block 31 to tighten the can lid 2 and increase the sealing. The bottom of the locking block 31 is engaged with the inner wall of the locking block 2. The rear surface of the locking block 31 is fixedly connected to the ring 38, which squeezes the elliptical block 32 and can drive the locking block 31 to move outward to release the limit of the can lid 2.

[0033] Reference Figure 1 - Figure 3The first locking block 31 is L-shaped, and its protruding bottom can be locked into the second locking block 39. The second locking block 39 can then pull the first locking block 31 to tighten the can lid 2 and the can body 1, increasing the seal. The outer wall of the can body 1 is fixedly connected to a supporting ring 38 and a positioning block 36 for stable movement. The ring 38 is slidably connected to the inner wall of the positioning block 36. The elliptical block 32 is elliptical in shape. When the ring 38 moves upward and presses the elliptical block 32, the special shape of the elliptical block 32 will cause the first locking block 31 to overcome the elastic force of the spring 33 and move outward, thereby releasing the locking between the first locking block 31 and the second locking block 39, making it easier to open the can lid 2. The ring 38 is slidably connected to the inner side of the first locking block 31, and the outer wall of the ring 38 is fixedly connected to a lever 37 that drives the ring 38 to move upward.

[0034] Reference Figure 1 - Figure 3 The rear surface of the locking block 31 is provided with a locking component, which includes a limiting block 61 that limits the locking block 31. The limiting block 61 is T-shaped, and a limiting groove 6 is opened at the bottom end of the ring 38. The limiting block 61 is movably inserted into the inner wall of the limiting groove 6. Inserting the T-shaped limiting block 61 into the limiting groove 6 can limit the locking block 31, thereby increasing the stability of the locking block 31 and the can lid 2, and thus improving the sealing performance of the connection between the can lid 2 and the can body 1.

[0035] Working principle: In use, the can lid 2 is placed on top of the can body 1. At this time, the fixing block 3 is positioned above the can body 1 along with the can lid 2. The cylinder 5 is activated, and the output shaft of the cylinder 5 extends, driving the guide block 4 to rise. This causes the second locking block 39 at the top of the guide block 4 to press against the bottom inclined surface of the first locking block 31. This causes multiple sets of first locking blocks 31 to move outward and stretch the spring 33, aligning the first locking block 31 with the inner wall of the second locking block 39. At this time, the ring 38 moves upward, and under the elastic force of the stretched spring 33, the first locking block 31 is reset. Insert the second locking block 39 into the inner wall, and then move the ring 38 downward so that the limiting block 61 is inserted into the limiting groove 6. Through the cooperation of multiple sets of locking blocks 31 and 39, the lid 2 is limited on the tank body 1. At this time, the output shaft of the cylinder 5 is moved downward, which drives the guide block 4 to pull the second locking block 39 downward, thereby driving the fixing block 3 and the lid 2 to move downward, so that the lid 2 is tightly fitted with the tank body 1, completing the installation and achieving a seal. This ensures that a closed space is formed inside the fermenter, preventing external impurities and microorganisms from entering and creating a stable environment for the fermentation process.

[0036] During fermentation, the cylinder 5 continuously provides upward pulling force, ensuring that the first locking block 31 and the second locking block 39 remain tightly connected, maintaining a good seal between the lid 2 and the tank body 1. At the same time, the limiting block 61 on the rear surface of the first locking block 31 can be inserted into the limiting groove 6 at the bottom of the ring 38 to limit the first locking block 31, preventing it from accidentally loosening due to vibration or other factors during fermentation. This further enhances the stability of the lid 2 installation, ensures the sealing of the fermentation tank, and ensures that the fermentation process is not disturbed by external factors.

[0037] When the fermentation tank needs to be opened, the output shaft of the adjusting cylinder 5 moves upward to release the tension on the locking block 31. At this time, by moving the lever 37, the ring 38 slides upward. The ring 38 moves upward along the inner wall of the positioning block 36, so that the limiting block 61 slides out of the limiting groove 6 and continues to move upward to contact the elliptical block 32 and squeeze it. Due to the special elliptical shape of the elliptical block 32, when squeezed, the locking block 31 will overcome the elastic force of the spring 33 and move outward. After the locking block 31 moves outward, the bottom of it is released from the locking block 39. At this time, the tank lid 2 can be easily removed from the tank body 1 to complete the disassembly operation.

[0038] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
