AI Technical Summary
[0003]而增碳剂在生产中需要进行烘干作业，通过去除其中的水分来增加性能，目前常见的烘干方式便是通过热风的方式来进行，通过加热后的风吹拂在增碳剂上来达到除湿烘干的效果，但是这样的方式存在一定的弊端，如在烘干过程中增碳剂大多直接堆积在烘干釜内，这就导致热风大多吹拂在增碳剂堆积的外部，往往外部都以充分烘干了，但是内部尚有水分存在，只能通过长时间的加热使内部也逐渐烘干，这样的方式效率较低，或者直接将物料倒入烘干筒内，在烘干的过程中通过搅拌杆的转动来对物料进行翻动，这样的方式虽然通过搅拌杆的翻动增加物料的受热面积来提高效率，但多用于大量增碳剂烘干作业，增碳剂量多堆积在釜内，搅拌棒也难以实现无死角的翻动，如烘干釜底部的沉积以及靠近搅拌杆根部的位置，随会受到翻动，但热气依旧难以直接进入，效率依旧相对较低
[0015]本实用新型提供一种用于生产增碳剂的烘干机，在进行增碳剂的烘干作业中，通过能够持续转动的放料筒，使物料在其中会随着放料筒的转动而翻转，从而不会长时间处于堆积的状态，并且四个扬料板的设计也可以在翻转的过程中，使物料由高处掉落形成扬料的效果，进一步的增加了增碳剂的受热面积，相较于目前，通过水平方向转动放料筒并扬料的方式代替垂直转动搅拌杆来进行翻料，不仅结构更为简单，同时使得物料受热面积更加的均匀，极大的提高了物料烘干的效率。

Description
Technical Field
[0001] This utility model relates to the field of carbon raiser production technology, and in particular to a dryer for producing carbon raisers. Background Technology
[0002] Carbon raisers are used to increase the carbon content during the steelmaking process, thereby improving the quality of the finished product.
[0003] Carbon retorts require drying during production to remove moisture and improve performance. The most common drying method is hot air drying, where heated air is blown onto the carbon retort to dehumidify it. However, this method has drawbacks. For example, during drying, the carbon retort often accumulates directly in the drying chamber, meaning the hot air mostly blows onto the outside of the accumulation. Often, the outside is fully dried, but the inside still retains moisture, requiring prolonged heating to gradually dry it as well. This method is inefficient. Alternatively, the material can be poured directly into the drying drum, and the material is turned over by rotating a stirring rod during drying. While this method increases the heating surface area and improves efficiency, it's mostly used for large-scale carbon retort drying. Since the carbon retort is mostly accumulated in the chamber, the stirring rod cannot achieve thorough turning. While deposits at the bottom of the drying chamber and areas near the base of the stirring rod are turned, hot air still cannot directly penetrate, resulting in relatively low efficiency.
[0004] Therefore, it is necessary to provide a new dryer for producing carbon raisers to solve the above-mentioned technical problems. Utility Model Content

[0011] Preferably, the discharge cylinder consists of a chassis, an outer ring wall, and an inner ring wall. The outer ring wall is fixedly installed on the outer curved wall of the chassis, and the inner ring wall is fixedly installed on the inner curved wall of the chassis.

[0014] Compared with related technologies, the dryer for producing carbon raisers provided by this utility model has the following beneficial effects:
[0015] This invention provides a dryer for producing carbon raisers. During the drying process, a continuously rotating feeding drum causes the material to tumble as the drum rotates, preventing it from accumulating for extended periods. The four lifting plates also allow the material to fall from a height during the tumbling process, creating a lifting effect and further increasing the heating area of the carbon raiser. Compared to current methods, this method of horizontally rotating the feeding drum and lifting the material instead of vertically rotating the stirring rod not only simplifies the structure but also ensures a more uniform heating area, significantly improving the drying efficiency.

The two barrier nets 8 are in close contact with the corresponding breathable pads 22 and fully clamp them, thereby reducing the force of the material impacting the breathable pad 22 when it is turned over.
[0035] The working principle of the dryer for producing carbon raisers provided by this utility model is as follows:
[0036] When drying the carbon raiser, the workers can first open the sealing door 3 and remove the four fastening bolts 13 one by one. This will release the limiting effect of the discharge cylinder, making it easier for the workers to remove the discharge cylinder.
[0037] After removing the discharge cylinder, the sealing plate 21 needs to be unscrewed first. Then, the carbonizer can be poured into the discharge cylinder (the carbonizer material accumulates between the outer ring wall 17 and the inner ring wall 18). The carbonizer accumulates to the middle of the lifting plate 19 at most. After the material filling is completed, the staff can screw the sealing plate 21 back on and put the discharge cylinder back into the drying chamber 2. When putting it in, align the four positioning plates 12 with the four inner chambers 20 and put it in. After it is fully put in, fix the discharge cylinder again with the four fastening bolts 13.
[0038] After completing the above operations, the drive motor 5 and multiple heating components 6 and 7 can be started. The multiple heating components 6 and 7 gradually heat the gas in the drying chamber 2 through electric heating. The multiple heating components 6 mainly heat the air inside the inner ring wall 18, while the multiple heating components 7 mainly heat the air outside the outer ring wall 17. After being heated, the gas will gradually pass through the air vent 22 and enter the discharge cylinder. Through this air intake method, the inside and outside of the discharge cylinder are exposed to hot air, so that the inside of the discharge cylinder can be heated evenly and quickly.
[0039] Meanwhile, after the drive motor 5 starts, the output shaft of the drive motor 5 rotates, driving the rotating shaft 9 to rotate, which in turn drives the support frame 10 and the outer frame 11 to rotate. During the rotation of the outer frame 11, due to the clamping of the inner receiving chamber 20 by multiple positioning plates 12, the material discharge cylinder will also rotate. At this time, the material inside the material discharge cylinder will also turn over. Due to the change in gravity, some material will fall from the lifting plate 19 after it is raised, thus achieving the effect of automatic material lifting. The barrier net 8 is mainly set to support, place, and disperse the force of material falling on the air cushion 22, thereby preventing the air cushion 22 from being damaged.
[0040] By using the above method, the material will not accumulate in the discharge cylinder for a long time, thereby maximizing the heating area. After the drying operation is completed, the drive motor 5, heating component 1 6, and heating component 2 7 are turned off. Then, the sealing door 3 is opened to remove the discharge cylinder and recycle the carbonizer.
[0041] Compared with related technologies, the dryer for producing carbon raisers provided by this utility model has the following beneficial effects:
[0042] This utility model provides a dryer for producing carbon raisers. During the drying process, a continuously rotating feeding drum causes the material to tumble as the drum rotates, preventing it from accumulating for extended periods. The four lifting plates 19 also allow the material to fall from a height during the tumbling process, creating a lifting effect and further increasing the heating area of the carbon raiser. Compared to current methods, this method of horizontally rotating the feeding drum and lifting the material instead of vertically rotating the stirring rod not only simplifies the structure but also ensures a more uniform heating area, significantly improving the drying efficiency.
