The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, bag extrusion device in the hanging bag type centrifugal machine described in the utility model, comprise: rotary drum 5, rotary drum 5 comprises again: at the bottom of rotary drum body 51 and the rotary drum 52,52 are arranged on the main shaft 7 at the bottom of the rotary drum, main shaft 7 is movably arranged on the base 14 by bearing block 15, be provided with filter bag 6 in the rotary drum 5, the inwall of rotary drum body 51 is provided with the annular air-pocket 8 of semi open model, its concrete set-up mode is: the inwall joint place of annular air-pocket 8 and rotary drum body 51 is by the trim ring screw in compression, filter opening is not offered at the position that position that rotary drum body 51 and annular air-pocket 8 fit and annular air-pocket 8 are covered on rotary drum body 51, makes annular air-pocket 8 form air cavity with the inwall of rotary drum body 51; The intake interface 53 of annular air-pocket 8 is located in the rotary drum body 51---and referring to shown in Figure 2, annular air-pocket 8 is between filter bag 6 and rotary drum body 51.Also be provided with the inlet duct 11 that matches with described intake interface 53 on the casing 2 of described centrifuge, as Fig. 2, Fig. 3 and shown in Figure 4, its concrete structure comprises: supporting base 21 and air inlet pipe 17, supporting base 21 is fixed by bolts on the casing 2, be provided with sliding cavity 212 in the supporting base 21, the bottom of sliding cavity 212 is provided with the telescopic hole that can allow air inlet pipe 17 stretch, the middle part of air inlet pipe 17 is provided with positive stop lug boss 171, positive stop lug boss 171 and stage clip 20 usefulness locking nuts 19 are fitted in the sliding cavity 212 of supporting base 21, also be provided with lock handle 18 on the described air inlet pipe 17, also be provided with the draw-in groove 211 that matches with lock handle 18 on the supporting base 21.
