The drum filter that provides in the utility model adopts following technology side: drum filter, comprise cylinder, be provided with deflector in cylinder inside, correspondence is provided with the powder gathering-device below deflector, described powder gathering-device comprises housing, be provided with the filtration string bag in enclosure interior, the top of filtering the string bag is provided with and is used for the charging aperture corresponding with the deflector of drum filter, the bottom of filtering the string bag is provided with discharge gate, below filtering the string bag, be provided with the discharging channel that is communicated with discharge gate, on discharging channel, be provided with the control valve that is used to control the discharging channel conducting, be provided with liquid level detection device on filtration string bag top, liquid level detection device is by control circuit and control valve control connection.
Described control valve is a pneumatic ball valve.
The bottom of the described filtration string bag is taper.
It is simple and reliable for structure for powder gathering-device in the utility model drum filter, safe, the danger of promptly having avoided operating personnel to be hindered by the high-temperature steam spray has guaranteed the filter effect of filter to recirculated water again, has improved the automaticity of drum filter simultaneously.
