在粮油和饲料工业中,易爆性粉尘和易燃性气体多,机械化和自动化的程度较高。由于气动技术具有防爆、抗震动和干扰以及便于实现自动化等突出优点,因而它更适用,且发展十分迅速。国外,早在1893年,吸送式气力输送装置正式用于车船码头吸送谷物。目前,已普遍用于粮食和饲料的贮运。七十年代,气动技术已用于粮油与饲料机械的压紧、包装、卸料、管
In the grain, oil and feed industries, there is more explosive dust and flammable gases and a higher degree of mechanization and automation. Due to its outstanding advantages of explosion-proof, vibration-proof and interference-free and easy to automate, pneumatic technology is more suitable and rapidly developed. Abroad, as early as 1893, suction-type pneumatic conveying device was formally used for sucking the grain by a motor vehicle dock. At present, it has been widely used in the storage and transportation of food and feed. Seventies, pneumatic technology has been used for grain and oil feed machinery compaction, packaging, unloading, pipe
