我厂铸工车间气流烘砂系统自1965年建成后,经过多年的生产实践,逐步改革。通过改变管路布置、改进喉管、更新除尘器等手段,实现了节能、高产、尾气排放不超标的目的。一、概况我厂铸工车间在1965年内迁建厂时,建了两条吸入式气力输送系统:一条是气流烘砂,用它来烘干露天堆放的湿新砂;一条是气力输送,用它来把烘干后堆存在砂库中的干砂,提升到混砂机上部平台的贮砂斗中。这两条系统投产初期的主要问题有两个:1.生产能力低。原设计每条系统的生产能力为
Our factory caster workshop sand drying system since 1965, after years of production practice, and gradually reform. By changing the pipeline layout, improve the throat, dust remover and other means to achieve energy-saving, high-yield, exhaust emissions do not exceed the purpose. I. Overview Our factory foundry workshop relocated to the factory in 1965, built two suction pneumatic conveying system: one is the air sand drying sand, it is used to dry the wet sand deposited in the open air; one is pneumatic conveying, use it to After drying the pile of sand stored in the reservoir of dry sand, sand mixer upgrade to the upper platform sand bucket. There are two main problems in the initial operation of these two systems: 1. Low production capacity. The original design of each system for the production capacity of
