Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is not subject in any way
Limitation, any changes and modifications made based on the utility model training centre, belongs to the scope of protection of the utility model.
As shown in figure 1, the utility model includes feeds of alumina pipe 1, tank body, discharge nozzle 13, chute 14 and slagging-off pipe 17,
The tank body includes cylinder 6, cone 12 and cover plate 3, and cone 12 is arranged between cylinder 6 and discharge nozzle 13, cover plate 3 and cylinder 6
Upper flanges 5 are connected, and the cartridge filter concentric with cylinder 6 is provided with the inside of tank body, and cartridge filter includes support 8 and is coated on support 8
Tank body is separated into inner chamber 21 and exocoel 20 by the filter screen 7 in outside, cartridge filter, and inner chamber 21 connects with discharge nozzle 13, and exocoel 20 is distinguished
Connected with feeds of alumina pipe 1 and slagging-off pipe 17.
More convenient in order to overhaul and change filter screen 7, the inwall of cone 12 is installed with support ring 11, the installation of the lower end of support 8
