The specific embodiment

Shown in Fig. 1-2, filter bag vibration lower discharging centrifuge comprises support 1, and support 1 upper end is equipped with casing 20, and the top of casing 20 also is provided with cover 14; On the described support 1 bearing block 3 is installed, main shaft 2 is arranged at bearing block 3 inside; Support 1 one sides are equipped with motor 17, and described motor 17 links to each other with driving pulley 16, are connected by conveyer belt 15 between driven pulley 7 and the driving pulley 16, and described driving pulley 16, driven pulley 7 and conveyer belt 15 all are arranged on the support 1; Described driven pulley 7 is connected with main shaft 2; Described support 1 lower end is provided with under-chassis 18, also is provided with outlet pipe 19 on the support 1;

Main shaft 2 inside are provided with a up and down guide post 9, and guide post 9 upper ends connect lifting cover 8, and the lower end is provided with a flexible member 10, and described lifting cover 8 is rigidly connected with loose flange 6; The top of described main shaft 2 arranges rotary drum 4, is provided with a movable filter bag 5 in the rotary drum 4, and casing 20 is positioned at the outside of rotary drum 4;

On the described cover 14 oscillating component 11 is set, be provided with directly over the guide post 9 and can overlap 8 axles that contact 22 with guide post 9 top liftings, axle 22 is connected with oscillating component 11, described oscillating component 11 is installed on the cover 14, axle 22 lower ends also are provided with a cushion pad 23, and cover 14 1 side inside also are provided with scraper 13; On the described cover 14 charge pipe 12 is set also, the movable filter bag 5 in charge pipe 12 and the rotary drum 4 links to each other.

Also be provided with a slip cap 21 between described guide post 9 tops and the main shaft 2.

Be communicated with by the filter bores that arranges on rotary drum 4 and the movable filter bag 5 between described outlet pipe 19 and the rotary drum 4.

Described oscillating component 11 is cylinder, and its control mode is pneumatic, hydraulic pressure or electronic.

During filter bag vibration lower discharging centrifuge work of the present invention, drive driving pulley 16, driving-belt 15, driven pulley 7 drive shaft 2 and drive rotary drum 4 rotations by motor 17, when reaching the charging rotating speed, the 4 inner injecting materials from charge pipe 12 to rotary drum, when reaching a certain amount of, rotating speed is brought up to maximum speed, and the liquid in the material passes movable filter bag 5 on rotary drum 4 walls and the filter bores on the rotary drum 4 and discharges from outlet pipe 19, and solid phase is trapped within movable filter bag 5 inside.

The rotating speed that reduces rotary drum 4 reaches discharging speed, starts most of cake layer under scraper 13 scrapings, and scraper 13 resets, oscillating component 11 actions, and axle 22 stretches out fast the end opening that withstands lifting cover 8 drive loose flanges 6 and movable filter bag 5 and moves downward fast in the lump; When resetting, axle 22 shrinks, the end opening of loose flange 6 and movable filter bag 5 moves upward under the effect of flexible member 10, thereby cause movable filter bag 5 vibrations, so repeatedly reciprocation cycle is thoroughly shaken off filter cake, reaches the purpose of removing filter cake, the whole course of work does not need manual intervention by the program full automatic working.
