Description

Technical Field

[0001] The utility model relates to a paddle with an adjustable shape in a fermentation tank. Background Art

[0002] A fermentation tank is an industrial device used for microbial fermentation. Its main body is typically a cylindrical stainless steel cylinder with a volume ranging from 1m³ to several hundred m³. Care should be taken during design and fabrication to ensure a rigorous and rational structure.

[0003] During the fermentation process, the fermentation tank needs to use fermentation blades to stir the fermented material. However, the form of the blades has a great influence on the fermentation results. During the production process, several types of blades are prepared, and then the blades are manually replaced in the tank, which is time-consuming, costly and labor-intensive. Utility Model Content

[0004] The purpose of the present utility model is to provide a paddle with adjustable shape in a fermentation tank to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a paddle with adjustable shape in a fermentation tank, comprising a paddle, a connecting part, a fixed rod and a rotating part, wherein the rotating part is horizontally arranged in the fermentation tank through a rotating axis, the connecting part is arranged at one end of the paddle close to the rotating part, the fixed rod is arranged at equal intervals around the outside of the rotating part, the fixed rod is inserted into the connecting part to realize the installation of the paddle, and a sliding component for adjusting the direction of the paddle is provided on the outside of the fixed rod.

[0006] Preferably, the sliding assembly includes a groove formed on the fixing rod and close to one end of the connecting portion, the groove is formed vertically from the surface of the fixing rod toward the center of the fixing rod, and a rotating unit is provided in the groove.

[0007] Preferably, the transmission unit includes a positioning column arranged in the groove, a long slot with open ends is transversely opened in the positioning column, and two connecting rods and rollers are arranged in the long slot.

[0008] Preferably, the two connecting rods are respectively arranged on the left and right sides of the long slot, and the roller is arranged between the two connecting rods.

[0009] Preferably, there are two grooves, which are respectively provided on the upper and lower sides of the fixing rod, and the transmission unit in each groove is arranged in reverse order of upper and lower directions.

[0010] Preferably, a socket adapted to the fixing rod is provided in the connecting portion.

[0011] Preferably, a slide rail is provided around the inner wall of the socket.

[0012] The technical effects and advantages of the utility model are as follows: the paddles in the fermentation tank are adjustable in shape. When fermentation is carried out in the fermentation tank, the rotating shaft drives the rotating part to rotate, so that the fixed rod drives the paddles to rotate. As the paddles stir the fermented material, the outer surface of the paddles will come into contact with the fermented material. At this time, with the obstruction of the fermented material, extrusion is generated, causing the roller to rotate and roll along the length direction of the slide rail, thereby driving the paddles to rotate. In this way, the angle of the paddles can be changed at any time. The same paddle can freely change the blade angle to adapt to the production of multiple strains. There is no need to frequently replace the paddles, saving cost and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] In order to save costs and time by not having to frequently replace blades 1, refer to Figure 1 、 Figure 2 and Figure 3The present invention relates to a fermentation tank comprising a paddle 1, a connecting part 2, a fixing rod 3 and a rotating part 4. The rotating part 4 is horizontally arranged in the fermentation tank through a rotating shaft. The connecting part 2 is arranged at one end of the paddle 1 close to the rotating part 4. The fixing rod 3 is arranged at equal intervals around the outside of the rotating part 4. The fixing rod 3 is inserted into the connecting part 2 to realize the installation of the paddle 1, and a sliding component for adjusting the direction of the paddle 1 is provided on the outside of the fixing rod 3. When fermentation is carried out in the fermentation tank, the rotating shaft drives the rotating part 4 to rotate, so that the fixing rod 3 drives the paddle 1 to rotate. As the paddle 1 stirs and ferments the fermented material, the outer surface of the paddle 1 will abut against the fermented material. At this time, with the obstruction of the fermented material, extrusion is generated, causing the roller 9 to rotate and roll along the length direction of the slide rail 11, thereby driving the paddle 1 to rotate. In this way, the angle of the paddle 1 can be changed at any time. The same paddle 1 can freely change the blade angle of the paddle 1 to adapt to the production of multiple strains. There is no need to frequently replace the blade 1, saving cost and time.

[0020] In order to improve the convenience of changing the angle of blade 1, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the sliding assembly includes a groove 5 formed on the fixed rod 3 and near one end of the connecting portion 2. The groove 5 is formed vertically from the surface of the fixed rod 3 to the center of the fixed rod 3. A rotating unit is provided in the groove 5. When the paddle 1 encounters resistance from the fermented material, the rotating unit slides along the length direction of the slide rail 11, thereby driving the connecting portion 2 to rotate on the outside of the fixed rod 3, driving the rotation of the paddle 1, and thus changing the angle of the paddle 1. The transmission unit includes a positioning column 6 provided in the groove 5. A long groove 7 with open ends is formed in the positioning column 6. Two connecting rods 8 and a roller 9 are provided in the long groove 7. The roller 9 can roll between the connecting rods 8 of the chain, and the setting of the roller 9 will not affect the insertion of the fixed rod 3 into the socket 10. The two connecting rods 8 are respectively provided on the left and right sides of the long groove 7, and the roller 9 is provided between the two connecting rods 8. Two grooves 5 are provided, one on the upper and one on the lower sides of the fixed rod 3. The transmission units in each groove 5 are arranged in opposite directions, with the two symmetrical rotation units better coordinating with the rotation of the propeller 1, making the propeller 1 smoother during rotation and improving the convenience of changing angles. A socket 10 is provided in the connecting portion 2, which is compatible with the fixed rod 3. The socket 10 facilitates the insertion of the fixed rod 3, allowing the connecting portion 2 to drive the propeller 1 to rotate accordingly. A slide rail 11 is provided around the inner wall of the socket 10.

[0021] During use, when fermentation is in progress in the fermentation tank, the rotating shaft drives the rotating part 4 to rotate, so that the fixed rod 3 drives the blade 1 to rotate. As the blade 1 stirs the fermented material, the outer surface of the blade 1 will come into contact with the fermented material. At this time, with the obstruction of the fermented material, extrusion occurs, causing the roller 9 to rotate and roll along the length direction of the slide rail 11, thereby driving the blade 1 to rotate. In this way, the angle of the blade 1 can be changed at any time. The same blade 1 can freely change the blade angle of the blade 1 to adapt to the production of multiple strains. There is no need to frequently replace the blade 1, saving cost and time.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
