我们介绍一种简易加热炉,其结构如图.它既不需要专用的高压或低压喷嘴,也不需要空气压缩机.而且点火很方便,用一小块油棉丝就能在冷炉膛的情况下把炉点燃.同时将清洗零件的废油或其它脏油用50~60目的粗网过滤一下就可直接燃烧,并保证油嘴不堵塞.炉温最高可达1300℃,每小时耗油量2~4公斤.很适合加热小型零件的连续生产.结构及操作特点如下:
We introduce a simple heating furnace, the structure shown in Figure 2. It does not require a dedicated high-pressure or low-pressure nozzles, air compressors are not required. And ignition is very convenient, with a small piece of oil cotton can be cold in the case Under the furnace lit. At the same time cleaning the parts of the waste oil or other dirty oil with 50 ~ 60 mesh coarse filter can be about to direct combustion, and to ensure that the nozzle is not blocked. Furnace temperature up to 1300 ℃, fuel consumption per hour 2 ~ 4 kg. It is suitable for heating small parts of continuous production. Structural and operational characteristics are as follows:
