Description

Technical Field

[0001] This utility model relates to the field of coal powder calcination technology, specifically to a coal powder drying device. Background Technology

[0002] Globally, with increasing environmental awareness and the urgent need to address climate change, countries are actively promoting adjustments to their energy structures, reducing reliance on high-pollution, high-carbon-emission fossil fuels, and shifting towards clean energy and technologies that efficiently utilize fossil fuels. As a crucial component of coal resources, improving the combustion characteristics of fine coal powder has a direct impact on increasing overall coal utilization efficiency and reducing pollutant emissions.

[0003] The existing Chinese utility model patent with publication number CN103542705A discloses a coal powder drying device comprising: a frame; a conveying mechanism arranged on the frame; a drying chamber mounted on the frame and above the conveying mechanism, the drying chamber containing infrared heating tubes; a feeder located at the inlet end of the conveying mechanism; and a discharger located at the outlet end of the conveying mechanism. When this coal powder drying device is in operation, the feeder spreads coal powder evenly on the conveying mechanism, which then delivers the spread coal layer into the drying chamber. The infrared heating tubes inside the drying chamber activate to dry the coal layer. After the coal layer is dried, the conveying mechanism delivers the dried coal layer to the discharger for collection. Because this coal powder drying device utilizes infrared light to dry the coal layer, the infrared light directly irradiates the spread layer on the conveyor belt, making it suitable for various coal samples, ensuring uniform drying, and achieving extremely high drying efficiency. It can continuously dry coal powder, solving the problem of online coal drying during automated sample preparation.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that pulverized coal needs to be dried before use. Traditional drying devices completely dry the moisture in the pulverized coal, leading to deviations in the combustion characteristics of the subsequent combustion system, high power consumption in the coal milling and clinker calcination processes, and an inability to achieve a suitable moisture content to improve combustion performance. Furthermore, after drying the pulverized coal, it is impossible to quickly remove the pulverized coal from the device. All these problems affect the use of the device. Utility Model Content

[0009] A heating structure is installed on the upper end of the basic structural component, and a controller is installed on the upper end of the heating structure. The controller is installed on the upper end of the heating structure to facilitate subsequent control of the drying degree of the heating structure.

[0019] Compared with the prior art, the present invention provides a coal powder drying device with the following beneficial effects:

[0020] 1. This utility model, through the design of the lifting structure component, includes a drive motor that connects and rotates an internal rotating rod. A connecting groove is installed at the upper end of the rotating rod, and a lifting plate is installed at the upper end of the connecting groove. The lifting plate lifts and dries the coal powder in the drying chamber, shortening the drying chamber by 1 meter, reducing drying time, and reducing the number of lifting plates. The upper end of the lifting plate is designed with an arc shape to facilitate subsequent material scattering. This structure, combined with the basic structure component, reduces the heating and drying time of the heating structure through a controller, preventing the complete drying of moisture in the coal powder. This effectively prevents the need for pre-drying of the coal powder before use. Traditional drying devices completely dry the moisture in the coal powder, leading to deviations in the combustion characteristics of the subsequent combustion system, higher power consumption in the coal mill and clinker calcination processes, and an inability to achieve a suitable moisture content to improve combustion performance.

[0021] 2. This utility model, through the setting of the tilting moving component, has a connecting block installed in the tilting moving component, and a lifting rod installed at the lower end of the connecting block. The left side of the upper drying chamber is tilted and raised by the lifting rod. A rotating shaft is installed on the right side of the drying chamber, and a support frame is installed at the lower end of the rotating shaft. The drying chamber is raised and lowered by the lifting rod, and the drying chamber is rotated by the rotating shaft, which facilitates the subsequent pouring out of the coal powder inside the drying chamber and effectively prevents the inability to quickly discharge the coal powder inside the device after drying.
