Our powder materials often encounter the requirements of continuous vacuum feeding in the conveying process. The intermittent vacuum conveying of ordinary vacuum feeding cannot meet the requirements. Our company has many years of application in vacuum feeding fans Experience, combined with customer requirements, put forward the working process of continuous vacuum fan feeding.
Working conditions of continuous vacuum suction fan loading system process:
Long distance transportation
Conveying with large height drop
Conditions requiring high transmission efficiency
Material has certain adhesion to prevent blocking
Conditions that require continuous feeding: extruder, pulverizer, etc.
Process method of continuous vacuum feeding fan system:
1. Use fan to feed, forming continuous vacuum feeding system
2.Continuous feeding is formed by connecting two ordinary vacuum feeding fans in series.
The above are the more common continuous vacuum conveying methods. Our company has a lot of project cases of vacuum wind phase feeding operation. The specific process is described in detail below.
Vacuum loading and conveying fan realizes the connection and loading case
First, the use of off the fan material, to achieve continuous vacuum loading
This system adopts shut-off fan discharge, which requires stricter process requirements for shut-off fan, and needs to have a certain tightness and good shut-off performance.
Process parameters:
Equipment material: stainless steel 304 / 316L / PTFE, fan adopts aluminum alloy
Fan pressure: ≥-40KPA
Configuration: high material level, inverter, vibrator, pulse backflush
Control system: PLC + touch screen, electronic circuit control
Advantages: high conveying efficiency, adjustable blanking efficiency, high cost performance
Second, continuous feeding is formed by connecting two ordinary vacuum feeding fans in series
This system connects the vacuum loader in series, while A loader sucks material, B loader discharges, and the whole work flow is cycled in turn.
Process parameters:
Equipment material: stainless steel 304 / 316L / PTFE
Configuration: switching valve, vibrator, pulse backflush system
Control system: PLC + touch screen, electronic circuit control
Advantages: high conveying efficiency, less material residue, high cost performance
