An air conveying chute is a device that uses air flow to transport granular materials along pipelines. It comes in three types: suction, pressure, and mixed. Its working principle is to utilize the kinetic energy of the air flow to suspend the granular materials and transport them along the pipeline with the air flow.
① Suction and delivery type. Once the exhaust fan is activated, the entire system reaches a certain vacuum level. Under the action of pressure difference, the airflow draws the material into the nozzle and transports it along the conveying pipe to the separator at the unloading point. After the material is separated from the airflow, it is discharged from the bottom of the separator. The airflow is purified through a dust collector and then discharged into the atmosphere through a silencer. Advantages include simple feeding and the ability to simultaneously吸取 material from several locations. However, the conveying distance is short, and the production rate is low. High sealing requirements are necessary.
② Forced Conveyance. The blower compresses air into the conveying pipe, where the material is introduced from the feeder. The mixture of air and material is conveyed to the discharge point along the conveying pipe. After separation by the separator, the material is discharged, and the air, after being purified by the dust collector, is released into the atmosphere. The characteristics are opposite to those of the suction type, allowing the material to be conveyed to multiple locations simultaneously, with a longer conveying distance and higher production rate. However, the structure is more complex.
③ Hybrid. A combination of the two aforementioned forms.
Reminder
You: This device is not suitable for materials with large particle size, high moisture content, and poor fluidization.
