Description

Technical Field

[0001] This utility model relates to the field of carbon fiber battery felt manufacturing technology, specifically a double-layer drive shaft material conveying device for a carbon fiber battery felt activation furnace. Background Technology

[0002] Carbon battery felt is a porous felt-like fibrous material with a broad three-dimensional network structure and a large specific surface area. This structure enables it to provide a large number of adsorption sites, thereby improving the adsorption capacity for ions or pollutants in the battery. It also exhibits good conductivity, corrosion resistance, and electrochemical stability, making it widely applicable as an electrode material in new energy fields such as flow batteries.

[0003] Carbon battery felt, as a core electrode material in flow batteries, can improve the charge-discharge efficiency and power density of the battery. Its excellent electrochemical performance and stability make it valuable for applications in energy storage devices such as vanadium redox flow batteries. The activation process is a critical step in its manufacturing, directly affecting the product's conductivity, porosity, and other properties. Traditional activation furnaces often use single-layer drive shaft conveying devices, which have the following drawbacks:

[0004] Efficiency bottleneck: The single-layer structure has limited material handling capacity, and the carbon fiber battery felt stays in the furnace for a long time, which restricts production efficiency and makes it difficult to meet the needs of large-scale production.

[0005] Insufficient uniformity: Single-layer conveying can easily lead to material accumulation and uneven distribution of activating gas, affecting the consistency of product performance.

[0006] Stability issues: The transmission system is prone to jamming due to uneven load, requiring frequent shutdowns for maintenance and affecting production continuity.

[0007] In view of this, we propose a double-layer drive shaft transmission material conveying device for carbon fiber battery felt activation furnace. Utility Model Content

[0030] Please see Figures 1-3 As shown, this utility model provides a technical solution:

[0031] A double-layer drive shaft conveying device for a carbon fiber battery felt activation furnace includes an activation furnace body 1, which has an activation area for activating carbon fiber battery felt. A double-layer drive shaft 2 is arranged in parallel inside the activation furnace body 1. The double-layer drive shaft 2 includes an upper drive shaft 3 and a lower drive shaft 4 that rotate synchronously. Both the upper drive shaft 3 and the lower drive shaft 4 extend along the length of the activation furnace body 1. An upper material conveying device 5 is provided on the upper drive shaft 3, and a lower material conveying device 6 is provided on the lower drive shaft 4. A feed port 7 and a discharge port 8 are respectively opened at the left and right ends of the activation furnace body 1. Both the feed port 7 and the discharge port 8 are provided with sealing devices.

[0032] In this technical solution, carbon fiber battery felt is placed at the starting ends of the upper conveying device 5 and the lower conveying device 6, respectively. The double-layer drive shaft 2 rotates, driving the upper and lower conveying devices 5 and 6 to operate synchronously, conveying the carbon fiber battery felt to the activation area within the activation furnace body 1. After activation, the activated carbon fiber battery felt is conveyed to the discharge port 8, completing the entire activation process. By modifying the activation furnace to use a double-layer drive shaft for material conveying, carbon fiber battery felt can be conveyed simultaneously in both the upper and lower layers, greatly improving the furnace's conveying capacity and shortening the residence time of the carbon fiber battery felt within the furnace, thus significantly improving the production efficiency of the carbon fiber battery felt. Furthermore, the double-layer drive shaft design provides greater stability, effectively preventing problems such as accumulation and jamming of the carbon fiber battery felt during conveying, ensuring the continuity and stability of production. It is worth noting that the sealing devices installed at both the inlet 7 and the outlet 8 utilize existing technology to prevent leakage of activation gas inside the activation furnace body 1.

[0033] In this embodiment, the upper drive shaft 3 and the lower drive shaft 4 are rotatably mounted on the front and rear inner walls of the activation furnace body 1 via bearings. The front end of the upper drive shaft 3 is fitted with a first sprocket 31, and the same first chain 32 is fitted on the outer side of multiple first sprockets 31. The front end of the lower drive shaft 4 is fitted with a second sprocket 41, and the same second chain 42 is fitted on the outer side of multiple second sprockets 41. A first gear 33 and a second gear 43 are respectively fitted on a set of upper drive shafts 3 and lower drive shafts 4 arranged vertically. A third gear 34 is meshed between the first gear 33 and the second gear 43. A drive motor 11 is fixedly mounted on the outer wall of the activation furnace body 1, and the output end of the drive motor 11 passes through the outer wall of the activation furnace body 1 and is fixedly connected to the third gear 34.

[0034] The third gear 34 is controlled to rotate by the drive motor 11. The third gear 34 drives the first gear 33 and the second gear 43 that mesh with it to rotate synchronously. Through the cooperation of the first sprocket 31, the first chain 32 and the second sprocket 41 and the second chain 42, the upper drive shaft 3 and the lower drive shaft 4 rotate synchronously.

[0035] In this embodiment, an upper baffle 12 and a lower baffle 13 are provided on the front side of the interior of the activation furnace body 1. The upper baffle 12 and the lower baffle 13 are fixedly connected to the inner wall of the activation furnace body 1. The upper baffle 12 and the lower baffle 13 are located above the upper drive shaft 3 and the lower drive shaft 4, respectively. An upper moving groove 14 and a lower moving groove 15 are respectively opened on the rear side of the upper baffle 12 and the lower baffle 13. The upper moving groove 14 and the lower moving groove 15 are correspondingly opened on the rear wall of the interior of the activation furnace body 1. The upper material conveying device 5 and the lower material conveying device 6 each include multiple material conveying units 51. Slider blocks 52 are symmetrically arranged on both sides of the material conveying unit 51. The sliders 52 are slidably arranged in the upper moving groove 14 and the lower moving groove 15.

[0036] By sliding the sliders 52 of multiple material conveying units 51 within the upper moving groove 14 and the lower moving groove 15, the movement of the material conveying unit 51 is made more stable, and the upper moving groove 14 and the lower moving groove 15 also limit the movement of the material conveying unit 51. The upper baffle 12 and the lower baffle 13 can also isolate the material conveying unit 51 from the first gear 33 and the second gear 43.

[0037] Furthermore, the material conveying unit 51 has a mesh structure in the middle, which can ensure the full flow of activation gas between the carbon fiber battery felts, making the carbon fiber battery felts more uniformly heated during the activation process, thus improving the activation effect and product quality.

[0038] In this embodiment, a material platform 9 is provided on the outside of the feed inlet 7 and the discharge outlet 8 to guide the carbon fiber battery felt to smoothly enter and leave the activation furnace body 1.

[0039] In this embodiment, a stainless steel porous tube 16 is fixedly installed on the inner top wall of the activation furnace body 1 along the length direction, and the stainless steel porous tube 16 is connected to the external steam generator through a pipeline.

[0040] In this embodiment, a temperature sensor 17 and a gas flow sensor 18 are also installed inside the activation furnace body 1. The temperature sensor 17 is used to monitor the temperature inside the activation furnace in real time, and the gas flow sensor 18 is used to monitor the activation gas in real time.

[0041] In this embodiment, the device also includes a control system, which is electrically connected to the drive motor 11, temperature sensor 17, gas flow sensor 18, and steam generator, respectively. The control system controls the operating speed and running time of the drive motor 11 to achieve precise control of the residence time and activation temperature of the carbon fiber battery felt in the activation furnace. Based on feedback signals from the temperature sensor and gas flow sensor, the control system automatically adjusts the operating speed of the power drive device and the flow rate of the activation gas to ensure that the carbon fiber battery felt is activated under optimal conditions.

[0042] In this embodiment, the carbon fiber battery felt activation furnace double-layer drive shaft transmission material conveying device is used by placing the carbon fiber battery felt at the starting end of the upper material conveying device 5 and the lower material conveying device 6 respectively.

[0043] Drive motor 11 drives double-layer transmission shaft 2 to rotate, driving upper material conveying device 5 and lower material conveying device 6 to operate synchronously, conveying carbon fiber battery felt to the activation area inside activation furnace body 1.

[0044] The control system automatically adjusts the operating speed of the power drive device and the flow rate of the activation gas according to the preset activation temperature and activation time, so that the carbon fiber battery felt can be activated in the activation area.

[0045] After activation, the drive motor 11 continues to drive the double-layer transmission shaft to rotate, conveying the activated carbon fiber battery felt to the discharge port 8, thus completing the entire activation process.

[0046] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.
