在以前的工作中，针对不断增加的废碳粉盒，工厂已经建造了一条物理回收生产线。然而，随着生产的进行，该生产线出现了严重的不足：(1)对收集的碳粉缺乏适当的处理技术；(2)生产线产生强烈的噪声，影响工人的健康。为了正确处理碳粉，研制了一种新的碳粉收集系统。设计了一种气流分离器，用于分离墨粉中的有机物质和无机物质。然后，分离的有机物质可以被焚烧，无机物可以被倾倒。通过理论分析和实验研究，得出了气流速度的最佳运行参数(13.5m/S)。为了控制噪声，测量了线路不同工序的噪声水平。结果表明，粉碎机(95.2分贝(A))和搅拌器/磁选机(AMS，91.9分贝(A))发出的噪声水平超过了《职业安全与健康标准》允许的噪声暴露水平(90分贝(A))。该生产线其他工序的噪声水平相对安全。开发了一种吸声罩来降低破碎机和AMS的噪音水平。噪声水平均降至67.6分贝(A)。本论文为废碳粉盒的工业化回收利用提供了重要的环境数据。
A physical recovery line had been constructed in plant for the increasing waste toner cartridges in previous work. However, with the production, severe lacks of the line emerged: (1) there was little proper technology of treating the collected toner; (2) strong noise was produced from the line and influenced the health of worker. For disposing toner properly, a new collected system of toner was developed. An air current separator (ACS) was designed to separate organic materials from inorganic materials of toner. Then, the separated organic materials can be incinerated and the inorganic materials can be dumped. Movement behaviors of toner particles in the ACS were analyzed, and the optimized operation parameter (13.5 m/s) of air current speed was obtained by theory analysis and experiments. For controlling the noise, noise levels emitted from the different process of the line were measured. The results indicated noise levels emitted from crusher (95.2 dB(A)) and agitator/magnetic separator (AMS, 91.9 dB(A)) were greater than the permissible noise exposure level of the Occupational Safety and Health Standards (90 dB(A)). The noise levels of other processes of the line were relatively safe. An acoustic hood was developed to reduce the noise levels of the crusher and the AMS. Then, the noise levels were both decreased to 67.6 dB(A). This paper provided important data for the environment on the industrialization of waste toner cartridges recovery.
