摘要： A furnace for producing oxides of lead includes an enclosure defining a furnace chamber, a feed inlet for feeding particulate lead into the chamber, and a discharge outlet for discharging the particulate lead outside the chamber. An array of horizontally disposed serially communicating tubes are arranged vertically within the chamber, communicating between the feed inlet and the discharge outlet. A rotating valve is associated with the feed inlet, for continuously feeding particulate lead into the number of tubes. Variable drive chain and sprocket combinations are associated with each of the tubes to convey the particulate lead serially along the tubes. The furnace includes electric heat tapes surrounding the tubes, for heating the particulate lead within the tubes while the lead is being conveyed along the tubes. The furnace can be used to produce red lead from leady-oxide or litharge by first supplying air or pure oxygen into the tubes. Leady-oxide is supplied at feed inlet and heated in the first tube to 1250°F to initiate the exothermic conversion of leady-oxide to litharge. Heat from the exothermic reaction occurring in the remaining tubes of the array is used to pre-heat the first tube. Litharge formed from the exothermic reaction is exposed to a lower temperature of 850° in the lowermost tubes of the array for formation of red lead. The travel rate of the litharge determines the percentage of red lead in the final product exiting the discharge outlet.

摘要翻译： 用于生产铅的氧化物的炉子包括限定炉室的外壳，用于将颗粒物料引入室中的进料口和用于将颗粒物料排出到室外的排出口。 水平布置的串联连接管的阵列在腔室内垂直布置，在进料口和排出口之间连通。 旋转阀与进料入口相关联，用于将颗粒状铅连续进料到多个管中。 可变驱动链和链轮组合与每个管相关联以沿着管顺序地输送颗粒。 炉子包括围绕管子的电热带，用于在导管沿着管传送的同时加热管内的颗粒引线。 该炉可用于通过首先向管中供应空气或纯氧来从铅氧化物或锂离子生产红色铅。 在进料口处供应氧化铅，并在第一管中加热至1250°F，以引发铅氧化物放电转化为硫化。 使用在阵列的剩余管中发生的放热反应的热量来预热第一管。 由放热反应形成的Litharge在阵列的最下面的管中暴露于850℃的较低温度以形成红色铅。 铅笔的行驶速率决定了离排放口的最终产品中红铅的百分比。
