Negative pressure conveying is to form a negative pressure air flow under the action of vacuum. Under the action of this air flow, bulk materials are transported to another container through the suction hose or pipe. Since the material is always in a vacuum state during transportation, even if the pipeline leaks, the material will not leak into the surrounding environment.

It is suitable for multi-point to one-point conveying. The transmission line is in the negative pressure pipeline state, and there is no leakage and pollution during the transmission process; The conveying state is uniform and continuous, and the conveying capacity can be adjusted; The air source device adopts dry negative pressure air source, which is simple and reliable; The separation device adopts high-efficiency filter material and pulse injection, with compact structure and high separation efficiency; The suction nozzle device can be specially designed according to different application occasions and process requirements; The equipment configuration of the conveying system is simple and the system investment is small; The system has low maintenance and convenient maintenance.

The negative pressure dilute phase pneumatic conveying system is an advanced material handling equipment, which has the characteristics of compact structure and reliable negative pressure dilute phase pneumatic conveying. It can transport loose and dry powdery or granular materials horizontally, obliquely and vertically. The negative pressure dilute phase pneumatic conveying is suitable for bulk, bulk transportation, bulk unloading, etc. in the production process.
