Description

Technical Field

[0001] This utility model relates to the field of battery negative electrode material processing technology, specifically a roller kiln conveying device. Background Technology

[0002] In the processing of battery anode materials (such as graphite-based anode materials), roller kilns are commonly used heat treatment equipment for sintering, drying, and other processes. The conveying device, as a core component of the roller kiln, is responsible for smoothly transporting the battery anode materials through the various heating zones of the roller kiln. When the existing roller kiln conveyor is in use, the conveyor rollers themselves do not have a direct heating function. During the heating process, uneven temperature distribution is likely to occur, which will affect the heat treatment effect of the battery negative electrode material. In addition, the surface of the conveyor roller is prone to material residue, which is difficult to clean. Long-term accumulation will further affect the conveying stability and material processing quality. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1-7This utility model provides a technical solution: a roller kiln conveying device, including an outer frame 1, with multiple conveying rollers 2 rotatably arranged inside the outer frame 1. The conveying rollers 2 are connected to a driving device via sprockets. Hollow shafts 201 are fixedly connected to the front and rear ends of the conveying rollers 2, and the hollow shafts 201 communicate with the interior of the conveying rollers 2. A heat exchange medium input channel 6 is fixedly installed on the front side of the outer frame 1, and a heat exchange medium output channel 7 is fixedly installed on the back side of the outer frame 1. The hollow shaft 201 at the front end of the conveying roller 2 is connected to the output end of the heat exchange medium input channel 6 via a rotary joint, and the hollow shaft 201 at the rear end of the conveying roller 2 is connected to the input end of the heat exchange medium output channel 7 via a selective joint. The heat exchange medium input channel 6 and the heat exchange medium output channel 7 are connected to the heat exchange medium circulation pipeline of the external heating equipment of the roller kiln (the heating equipment can be a guide pipe). A hot oil circulation system is provided. An auxiliary temperature control component 8 is provided below the conveying roller 2. The auxiliary temperature control component 8 provides auxiliary heating for the conveying roller 2 and cleans the surface of the conveying roller 2. A limit component 4 is provided on the top of the outer frame 1. The limit component 4 limits the negative electrode material being conveyed on the conveying roller 2. An auxiliary support component 3 is provided on the side of the outer frame 1. The high temperature heat exchange medium is introduced into the hollow shaft 201 through the heat exchange medium input channel 6, and then into the conveying roller 2 to directly heat the conveying roller 2. Thus, when the conveying roller 2 conveys the negative electrode material, the conveying roller 2 can directly heat the negative electrode material to ensure the heating effect. The auxiliary temperature control component 8 is set to adjust the temperature of a single conveying roller 2 to further ensure the heating effect of the negative electrode material and to clean the residue on the surface of the conveying roller 2. The auxiliary temperature control component 8 includes an arc-shaped seat 801, which is fixedly installed on the inner side of the outer frame 1. A heater 802 is installed on the front side of the arc-shaped seat 801. A groove is opened on the inner side of the arc-shaped seat 801, and a heating rod 803 is fixedly installed in the groove. The front end of the heating rod 803 is connected to the heating end of the heater 802. The arc-shaped seat 801 is set up to install the heater 802. The heater 802 heats the heating rod 803, so that the heating rod 803 and the conveying roller 2 are heated, thereby achieving secondary heating to adjust the temperature of a single conveying roller 2 and further ensure the heating effect on the negative electrode material. The auxiliary temperature control component 8 also includes an arc-shaped metal scraper 804 and a discharge through hole 805. An arc-shaped seat 801 is fitted over the conveyor roller 2, and there is a gap between the inner side of the arc-shaped seat 801 and the outer wall of the conveyor roller 2. The arc-shaped metal scraper 804 is fixedly installed at the top of the arc-shaped seat 801, and the end of the arc-shaped metal scraper 804 away from the arc-shaped seat 801 contacts the outer wall of the conveyor roller 2. The discharge through hole 805 is opened at the lowest point of the inner side of the arc-shaped seat 801, and the length of the discharge through hole 805 is the same as the length of the arc-shaped metal scraper 804. The arc-shaped metal scraper 804 is used to scrape off the residue on the surface of the conveyor roller 2. Since the arc-shaped metal scraper 804 is arc-shaped, most of the residue scraped off by the arc-shaped metal scraper 804 falls along the outer curved surface of the arc-shaped metal scraper 804, and some falls into the gap between the arc-shaped seat 801 and the conveyor roller 2, and then falls into the discharge through hole 805. A roller support 9 is fixedly installed on the inner wall of the conveying roller 2. The roller support 9 is cross-shaped and is used to support the internal space of the conveying roller 2 to prevent the conveying roller 2 from flattening after long-term use. The limiting component 4 includes a fixed plate 401. Two fixed plates 401 are provided and are symmetrically arranged at the front and rear relative to the center of the conveying roller 2. An internal threaded sleeve 403 is fixedly installed on the inner wall of the fixed plate 401. The internal threaded sleeve 403 is internally threaded and connected to a threaded rod 404. The end of the threaded rod 404 facing the conveying roller 2 is rotatably connected to an adjusting limiting plate 402 through a bearing. The position of the adjusting limiting plate 402 relative to the fixed plate 401 is adjusted by rotating the threaded rod 404. The negative electrode material conveyed on the conveying roller 2 is limited by the two adjusting limiting plates 402 to prevent the negative electrode material from deviating. A guide rod 11 is fixedly installed on the outer wall of the adjusting limit plate 402 facing the fixed plate 401. A guide ring 10 is slidably sleeved on the outer wall of the guide rod 11. The guide ring 10 is fixedly connected to the fixed plate 401. A handle 12 is fixedly installed on the end of the threaded rod 404 away from the adjusting limit plate 402. The guide rod 11 and the guide ring 10 are provided to increase the guiding structure of the adjusting limit plate 402 and prevent the adjusting limit plate 402 from tilting. The handle 12 is provided to facilitate the user to rotate the threaded rod 404. The auxiliary support assembly 3 includes a connecting seat 301, which is fixedly connected to the outer frame 1. An adjusting rod 302 is internally threaded onto the connecting seat 301. A support foot 303 is provided at the bottom end of the adjusting rod 302. The support foot 303 is detachably mounted to the adjusting rod 302 via a fixing nut 305. An adjusting nut 304 is fixedly installed on the adjusting rod 302. By rotating the adjusting nut 304 with a tool, the adjusting rod 302 is rotated, thereby adjusting the length of the adjusting rod 302 extending from the connecting seat 301, and thus adjusting the distance between the support foot 303 and the outer frame 1. This allows the support foot 303 to provide auxiliary support to the outer frame 1 even when the ground is uneven. Below the auxiliary temperature control component 8 is a waste collection box 5, which is located below the discharge through hole 805. The width of the waste collection box 5 is greater than the length of the discharge through hole 805. Handles 501 are provided at both the left and right ends of the waste collection box 5. The waste collection box 5 is designed to catch the residue that is scraped off by the arc-shaped metal scraper 804. The handles 501 make it convenient for users to pull the waste collection box 5.

[0017] Working principle: During use, before the negative electrode material is conveyed on the conveyor roller 2, the distance between the two adjusting limit plates 402 is adjusted according to the specifications of the negative electrode material. Then, the external heating equipment of the roller kiln is turned on, allowing the heat exchange medium to enter the heat exchange medium input channel 6. It then flows sequentially through the hollow shaft 201, the conveyor roller 2, the hollow shaft 201, and the heat exchange medium output channel 7 before returning to the heat exchange medium circulation pipeline of the external heating equipment of the roller kiln. During this process, the heat exchange medium heats the conveyor roller 2, causing it to directly heat up. The negative electrode material is then heated. At the same time, the heaters 802 corresponding to different conveyor rollers 2 can be turned on or off as needed to adjust the temperature of a single conveyor roller 2 and ensure the heat treatment effect on the negative electrode material. When the conveyor roller 2 rotates, the arc-shaped metal scraper 804 will scrape off the residue on the conveyor roller 2. Most of the residue falls along the outer curved surface of the arc-shaped metal scraper 804, some falls into the gap between the arc-shaped seat 801 and the conveyor roller 2, and then falls into the discharge through hole 805. Finally, all of them fall into the waste collection box 5.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
