Utility model content
The purpose of this utility model is to provide inside and outside rotary drum (cone-element) Combined double-stage centrifugal filtration centrifugal discharge device, this device has increased an interior rotary drum of installing with one heart, not only played the effect of pre-separation, also played from scarifying process, be conducive to further reduce the final water capacity after feed separation, the setting of twin-stage rotary drum (cone-element) not only can be carried out double-stage filtering to material, improves quality and the efficiency of filtering, and has also played the effect of Automatic continuous discharging.
The technical solution adopted in the utility model is: inside and outside rotary drum (cone-element) Combined double-stage centrifugal filtration centrifugal discharge device, it is characterized in that, and this device comprises outer drum mechanism (1), interior rotary drum mechanism (2) and bearing chamber mechanism (4); Described interior rotary drum mechanism (2) is arranged on outer drum mechanism (1) inside, and interior rotary drum mechanism (2) is connected with bearing chamber mechanism (4) by (3) at the bottom of outer drum with outer drum mechanism (1); (3), outer drum body (12) and outer leaching net (11) at the bottom of described outer drum mechanism (1) comprises outer drum, at the bottom of outer drum body (12) is back taper and is installed on outer drum, (3) are upper, and outer leaching net (11) is installed in outer drum body (12); Described outer leaching net (11) small end is by press strip A(5) to be pressed in outer drum body (12) upper, outer leaching net (11) is held by trim ring A(6 greatly) be fixed on outer drum body (12) upper end; Described interior rotary drum mechanism (2) comprises interior rotary drum body (22) and Inner filter net (21), at the bottom of interior rotary drum body (22) is back taper and is installed on outer drum on (3), interior rotary drum body (22) upper end is provided with cloth tray (13), and Inner filter net (21) is installed in interior rotary drum body (22); Described Inner filter net (21) small end is by press strip B(9) to be pressed in interior rotary drum body (22) upper, Inner filter net (21) is held by trim ring B(10 greatly) be fixed on interior rotary drum body (22) upper end.
The beneficial effects of the utility model are: (1) this device has increased an interior rotary drum of installing with one heart, and because interior rotary drum cone angle is less, the speed of centrifugal discharge is slower, and material is relatively long at the disengaging time of interior rotary drum, has played good pre-separation effect.Meanwhile, material draws off by interior rotary drum automatic centrifugation the process that is distributed to outer drum, be one from scarifying process, be conducive to further reduce the final water capacity after feed separation.
(2) design of taper twin-stage rotary drum, not only can play to material the effect of twin-stage continuous filtration, improve quality and the efficiency of filtering, can also reach the effect of automatic centrifugation discharging, manpower and cost had both been saved in automatic centrifugation discharging, can not destroy product quality again.
