Description

Technical Field

[0001] This utility model relates to the field of FDY oil reaction vessel technology, specifically to a fluid mixing structure for FDY oil reaction vessels. Background Technology

[0002] FDY ink is mainly composed of surfactants, which can form a directional adsorption layer on the surface of chemical fibers, i.e., ink.

[0003] According to the patent titled "An FDY Oil Mixing and Stirring Device" (Patent Publication No.: CN222724163U, Patent Publication Date: 2025-04-08), it includes: a stirring mechanism and a stirring tank. The stirring mechanism includes a fixed base, and the upper surface of the fixed base is provided with a U-shaped limiting groove, a stirring assembly, and a vibration assembly. The vibration assembly includes a vibration motor, a vibration shaft, and an elastic vibration rod. The vibration motor is fixedly mounted on the upper end of the fixed base, and the vibration shaft is drivenly connected to the output end of the vibration motor. The elastic vibration rod is fixedly mounted on the upper end of the vibration shaft. A plurality of vibration blocks are arranged in a circular array on the outer wall of the stirring tank. During use, the vibration assembly strikes and vibrates the stirring tank, causing uniform vibration inside the tank. This shakes off the raw materials adhering to the inner wall of the stirring tank evenly, resulting in more thorough mixing inside the tank and preventing waste caused by FDY oil raw materials adhering to the inner wall of the stirring tank.

[0004] Based on the aforementioned existing technology, current fluid mixing structures for FDY oil reactors still have the following problems: the stirring rods in existing fluid mixing structures for FDY oil reactors are usually fixed baffles. Although fixed baffles can effectively prevent vortices, dead zones or shadow zones of the fluid can easily form behind them, at the connection with the reactor wall, and on the baffle itself. Especially for viscous FDY oils, the material is more likely to adhere to the surface and back of the fixed baffle, and long-term accumulation will lead to a decrease in mixing uniformity. Therefore, this utility model provides a fluid mixing structure for FDY oil reactors. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a fluid mixing structure for FDY oil reactors. This structure solves the following problems associated with existing fluid mixing structures for FDY oil reactors: The stirring rods in existing fluid mixing structures for FDY oil reactors are typically fixed baffles. While fixed baffles effectively prevent vortices, dead zones or shadowed areas can easily form behind them, at the connection point with the reactor wall, and on the baffle itself. Especially for viscous FDY oils, the material is more likely to adhere to the surface and back of the fixed baffle, leading to a decrease in mixing uniformity over time.

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.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] The fluid mixing structure of the FDY oil reaction vessel includes a barrel body 1, and a mixing mechanism 2 is provided inside the barrel body 1 to improve the mixing uniformity. The mixing mechanism 2 includes:

[0025] The oscillating unit 21 is located inside the barrel mechanism 1 and includes a rotating drum 211. Several rotating shafts 212 are rotatably mounted on both the left and right sides of the rotating drum 211. A stirring rod 213 is fixedly mounted on the outer end of the rotating shaft 212, and a linkage disk 214 is fixedly mounted on the inner end of the rotating shaft 212. A linkage column 215 is fixedly mounted on the inner side of the linkage disk 214. The oscillation of the stirring rod 213 is achieved by the reciprocating rotation of the linkage disk 214, thereby improving the mixing uniformity.

[0026] The drive unit 22 is located above the rotating drum 211 and is used to drive the rotating drum 211.

[0027] In this embodiment, the drive unit 22 further includes several linkage rods 216. The linkage rods 216 are fixedly connected to each other by connecting posts 217. The linkage posts 215 slide inside the linkage rods 216. The linkage posts 215 slide back and forth inside the linkage rods 216 by moving the connecting posts 217 and the linkage rods 216 up and down, thereby realizing the reciprocating rotation of the linkage disk 214.

[0028] The drive unit 22 includes several linkage rods 216, which are fixedly connected to each other by connecting columns 217. The linkage column 215 slides inside the linkage rod 216. The linkage column 215 is driven to slide back and forth by the up and down movement of the connecting column 217 and the linkage rod 216, thereby realizing the reciprocating rotation of the linkage disk 214, making the swing of the stirring rod 213 more coordinated and uniform.

[0029] In this embodiment, a fixing plate 2110 is fixedly installed at the bottom of the inner cavity of the top box of the rotating drum 211, and a micro motor 2111 is fixedly installed on one side of the fixing plate 2110. The output end of the micro motor 2111 passes through the fixing plate 2110 and is fixedly installed on a rotating disk 2112. A connecting rod 219 is rotatably installed on one side of the rotating disk 2112 near the edge, and a connecting seat 218 is rotatably installed at the bottom end of the connecting rod 219. The connecting seat 218 is fixedly installed on the top of the uppermost linkage rod 216 inside the rotating drum 211.

[0030] The micro motor 2111, model KV3SF-8521F-WR, is electrically connected to an external power source and can be turned on and off via a human-operated control panel. The micro motor 2111 drives the rotating disk 2112 to rotate, which in turn pushes the uppermost linkage rod 216 up and down through the connecting rod 219 and the connecting seat 218, thus achieving effective control over the oscillation frequency and amplitude of the stirring rod 213, enhancing the flexibility of operation and the adaptability of stirring.

[0031] In this embodiment, the barrel mechanism 1 includes a support 11, a fixing ring 12 is fixedly installed on the crossbar of the support 11, and a mixing barrel 13 is fixedly installed inside the fixing ring 12, and a rotating drum 211 is rotatably installed inside the mixing barrel 13.

[0032] The mixing tank 13 is securely mounted on the bracket 11 by the fixing ring 12, while the rotating drum 211 is rotatably mounted inside the mixing tank 13. The structure is stable and reasonable, providing a reliable support environment for the stable operation of the mixing mechanism 2.

[0033] In this embodiment, a feed pipe 15 is fixedly installed on the top of the mixing tank 13, and a discharge pipe 14 is fixedly installed on the lower front side of the mixing tank 13.

[0034] The mixing tank 13 is equipped with a feed pipe 15 at the top and a discharge pipe 14 at the lower front side, which facilitates the addition and discharge of materials.

[0035] In this embodiment, the drive unit 22 includes a large conical tooth 221 fixedly installed on the upper surface of the rotating drum 211, a stirring motor 222 fixedly installed on the top of the mixing tank 13, and a small conical tooth 223 fixedly installed at the output end of the stirring motor 222, and the small conical tooth 223 and the large conical tooth 221 are meshed together.

[0036] The stirring motor 222 is model OMV800. It is electrically connected to an external power source and can be started and stopped by a human-operated control panel. It drives the rotating drum 211 to rotate through the meshing transmission of the small bevel gear 223 and the large bevel gear 221. It has a compact structure and high transmission efficiency, providing stable and reliable rotational power for the mixing mechanism 2.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, the material is first fed into the mixing tank 13 through the feed pipe 15. The stirring motor 222 drives the small conical teeth 223 to rotate, which in turn drives the stirring motor 222 to rotate. The rotation of the stirring motor 222 drives the large conical teeth 221 to rotate, thus mixing the material inside the mixing tank 13.

[0039] Then, when the rotating drum 211 rotates, the micro motor 2111 runs and drives the rotating disk 2112 to rotate. The rotating disk 2112 drives the linkage rod 216 and the connecting column 217 to move up and down reciprocally through the connecting rod 219. When the linkage rod 216 moves up and down reciprocally, the linkage column 215 slides inside the linkage rod 216. The linkage column 215 drives the linkage disk 214 to rotate reciprocally. The linkage disk 214 drives the stirring rod 213 to rotate reciprocally through the rotating shaft 212.
